Randomly collect evenly distributed points on the tested surface of the wearing parts, and polish them to make the surface material accuracy reach 2um. The polishing area is larger than the carbon test punch. The wearing parts are randomly fixed on a carrier with a certain rigidity, and the average precision is not limited to the IHRC. The average value of the three points is the hardness of the wearing parts. For the determination of the hardness difference of the lifting plate, the dividing wheel, the directional sleeve, and the protective electrode, one point should be selected from each surface to be determined. After the measurement, the maximum and minimum values and the half-mean value of the three-point hardness are determined according to the measurement results. 4.2 Determination according to JBS/T536.1. 4.3 Test items according to JB2670 4.4 Determination of the shooting belt area
Paint a black paint on a suitable wooden board or lay a thick paper and mark the required area. Place the left side on a workpiece carrier of the same weight as the workpiece to be shot. Start the equipment. Add a small amount of projectiles into the bucket of the throwing belt and shoot for a few seconds. Turn off the equipment. Remove the wooden board and check the position, shape and area of the shooting belt. 5
4.5 Determination of pellet efficiency
IB/T 8355--96
Automatic equipment, make and adjust the pellet supply door so that the total pellet supply reaches the total power within the range of the motor power of the pelletizer. The inlet pipe should not overflow with pellets. After 1min, it should still be filled and overflow. Then close the pellet supply door, stop supplying pellets, remove the pellet inlet bucket, and replace a container under the pellet supply door for positive measurement. Open the pellet supply door and the stopwatch at the same time. When the pellet supply door is closed to 1mm, close the pellet door. When there is no obvious pellet out of the pellet discharge, close the pelletizer, weigh the pellets in the pelletizer, and use the same method to calculate the pellet quantity (unit: k/kg). While measuring the pellet filling, measure the motor efficiency corresponding to the measured pellet quantity, and take the arithmetic mean value as the load power of the motor (unit: k).
The ratio of the shot volume of the shot blasting machine to the negative power of the motor is the shot blasting rate [measured in kg/(min-kw)]. 4. Determination of the hardness of the core nozzle
Three points on the outer diameter of the nozzle are randomly and evenly distributed according to the provisions of 1. 4. To measure the shot blasting rate
Put a spherical gold bottom blasting machine on the workpiece support of the equipment, so that the spray gun is facing the blasting machine mouth, and the nozzle and the container mouth should be deep. Take a small amount of anti-flying air to prevent the ejection of the ejection from the nozzle and all the ejection from the nozzle flows into the container. Adjust the working pressure of the blasting machine to 0.55MPa. When the workpiece support is not running, the blasting machine is operated and the scale is used to select the time. When the blasting machine is closed at 1m, the net weight of the projectile in the blood container is weighed, and the average value is the shot blasting rate (measured in kS/nin). While measuring the reduction, the blasting is carried out corresponding to the measured blasting volume! The compressed air elimination disk is set, and the arithmetic mean is the nozzle compressed air consumption (the unit of measurement is /i. The compressed air consumption of the spraying with the shot number is the shot rate. 4. Determination of the maximum micro-recording force of the linear vibrating screen During the idling process, a rejection meter is used with a light indicator to record the linear vibrating screen excitation rate. The mass of the deflection block and the maximum eccentricity (the average of the calculated and measured values can be taken) are calculated as the vibration force according to formula (1). The excitation force of the deflection is the maximum excitation force of the linear vibrating screen. Force:

4.9 Self-reporting screen, wave simple screen end in accordance with the public secret of the projectile base determination n
out of the straight line according to the principle of dynamic, the front row of the fall of the division of the fall device, so that the number of people on the screen all the frequency of the boarding device, the outside hand I body The specified workpiece is loaded with the maximum load capacity, and the equipment is started to make the projectiles enter the normal cycle. The waste material is 1mn away from the screen outlet of the simple screen. After shutting down, the angle in the container is reduced to a large speed, and the waste material is screened according to the classification specified in GB61.~G1. The mass of the projectiles that meet the nominal size is weighed, and the mass of the projectiles is calculated according to the ratio of the mass of the projectiles to the actual production of the linear vibrating screen and the simple screen.
4.10 The impurities in the pellets and the pellets that meet the nominal size are Determination of qualified pellet content in pellet tray and pet Under the condition that the equipment is running under load and has formed a staggered cycle, open the pellet gate for 3 minutes, and sample evenly over the entire length of the sand separator (the sampling lever should be below the first puzzle plate). Each sample is 5 mg, and a total of three samples are taken. After each sample is weighed with an accuracy of 0.91g, the pellets and impurities are separated and the impurities are weighed. The mass content is calculated according to the percentage of the taken amount. The average of the three calculations is the impurity content in the pellets. The pellets after each separation are weighed in the same way. After the pellets are weighed, the pellets are screened or counted according to the tolerance of the pellet size and the test method specified in GB34GB87 or related technical documents. The pellets are weighed to determine the percentage of pellets with the nominal size in the pellets. When the equipment is under normal load and the cycle has been formed, take a sample at the waste outlet of the separator. Each sample is 1g+ and a total of three samples are taken. After each sample is weighed with an accuracy of 0.01, the pellets and impurities are separated. At the same time, the broken pellets that cannot be recycled in the E
JB/T8355--96
shot are removed, and the pellets that can be recycled are weighed. The qualified pellet content is calculated by weight percentage, and the arithmetic average of three calculations is the qualified pellet content in the material. 4. The dust emission concentration is determined according to the relevant regulations of the national environmental protection department: 4.12 Determination of the productivity of the pellet circulation system: 1.1 times the maximum allowable addition of the equipment + 1.1 times the allowable addition of the workpiece carrier The maximum bearing capacity of the detailed description is loaded on the workpiece, and the equipment is started to carry out the round-tripping and filling processing. During the working process, the shot circulation system should not be blocked or stopped, and the plan is coordinated. It is determined that the yield does not meet the requirements. At the same time, the following measurements are no longer carried out. It is assumed that each pair of workpieces has completed a cycle of round-tripping and the convex machine is shut down. A container is placed at the discharge 1.1 of the elevator to collect the mixture of shots, sand, etc. from the elevator. When the machine is started again, all the shots, sand, etc. can flow into the container. The equipment is started again according to the above conditions for 1m, and the machine is closed. After the machine is finished, the mixture of shot, sand, etc. in the ship is weighed (the unit of measurement is k/min). This information is the production rate of the shot ring system. 4.13 Machine productivity
The maximum load allowed by the workpiece carrier is splashed on the workpiece. The equipment is started to use appropriate shot to blast the workpiece. The workpiece is subjected to shot blasting. The time is measured by a scale until the shot blasting effect meets the requirements of the workpiece. The ratio is calculated according to the weight or equivalent value of the workpiece and the processing time. The ratio is the whole machine productivity. 4.14 When the parts are running idly, the noise is measured according to the provisions of JB/6331.2. 4.15 The method for measuring the surface roughness of the workpiece after oil shot blasting is to remove all the attachments and debris on the surface of the workpiece to be tested after oil shot blasting, and observe the surface of the workpiece under scattered sunlight or artificial lighting conditions.The surface of the workpiece should be inspected with normal vision, and the results of the daily measurement should be made in combination with the situation of the shot coverage.
4.16 Determination of the surface roughness of the workpiece after shot peening 4.1. Remove all dust and debris on the surface of the workpiece to be tested during the shot peening process. 4.16.2 Use a surface roughness comparison sample block with a similar material and roughness to the workpiece to compare with the surface of the workpiece to be tested. When comparing, the comparison sample block should be placed close to a certain area of the workpiece to be tested, and the scratched surface should be compared with four different parts of the comparison sample. The roughness of the workpiece surface can be determined by visual perception. 4.16.3 During the determination process, the comparison sample block should be placed under the same conditions as the workpiece (such as composition, light, etc.). 4.1i.4 For workpieces with high surface requirements (such as R of 0.2m, 0.44m, 0.8m), a comparison test can be performed by placing the magnifying glass in the space between the test surface and the comparison sample surface: the magnifying glass should not exceed the scope of the magnifying glass.
4, 1.5 If the surface roughness and fineness cannot be measured by comparison sample due to the influence of the surface coverage of the workpiece, a surface roughness test should be performed, and a half-plate of the same specification processed under the same conditions as the test surface should be used for measurement according to the specified conditions. 4.16.6 When there is a dispute over the measurement result, a method with higher accuracy than the above method can be used. The method of determining the high quality shall be as follows. 4.17 For the determination of the shot peening strength of the workpiece after shot peening, see Appendix A (Standard Appendix). 4.18, for the surface of the workpiece after shot peening. Determination of yield 4.18.1 Definition of surface coverage
The ratio between the area occupied by the bullet marks and the area required to be shot peened at a specified position on the surface of the workpiece to be shot peened is called the surface coverage ratio
The surface coverage ratio is expressed as a percentage. When the surface of the workpiece is equal to or less than 2% of the initial surface, the measured surface yield ratio is defined as 100.
4.18.2 On the surface of the workpiece after shot peening, select the measured points and magnify them. A large mirror with a magnification of at least 50 times is used for daily measurement and the original surface area on the sprayed surface is counted: 102cm×102mum or 1C4cm surface! The percentage of the surface area occupied by all interception marks in the model is calculated, and the result is the surface coverage rate. 4.1, 3 If the agreement stipulates a surface coverage rate of more than 100%, the model spraying time is used for calculation. Example: 200 surface coverage rate means that the upper source is sprayed (spraying> time is twice the 10C% surface coverage rate. 7

Determination of shot peening intensity
(Standard time record)
The surface layer of the test piece undergoes plastic deformation under the impact of the projectile, which causes the test piece to bend toward the pool in a ball-shaped shape (to A1). The distance between the reference point and the ball is measured, which is called the arc height. The reference plane with a diameter of &tt|| is used as the height proof!
Figure A1 After the test piece is thrown, the shape of the hyperbolic spherical surface and the height of the test piece are measured. When the technical parameters (including projectile diameter, projectile speed, ground shot peening amount, ground shot peening time, angle, etc.) remain unchanged, the initial arc height increases with the time (or the number of shot peening times). But as the piece changes gradually, the amount reaches the range and "or" standard, and the height changes linearly with the time of peening. This process forms a curve, the "height time curve" (Figure A2). The point of deviation from the line is called the point A, B), and its ordinate is called the mean height.

Figure 42 High line
A2 shot peening nine strong Definition and expression method of shot peening intensity
The sub-height value at the saturation point on the "height·time" curve is called the shot peening intensity. The shot peening intensity is expressed by the tensile height value (in units of degrees) measured by the standard test piece. Example: The test height measured by the A-type standard tensile test piece is C.36mm, which is expressed as 0.36A. A3 shot peening intensity detection equipment
Other shot peening intensity detection equipment includes C5616T gauge, C6616-1 standard double height test piece and C6616-■ tension module. A3.1C: B616-I standard height test piece is divided into three types: N, A, and C. Type A test piece is a commonly used test piece. When the ground shot peening intensity (saturation height) measured by the A-type test piece is less than 0.15mm (time 0.15A), it should be adopted Use N-type trial production to determine the shot peening strength: When the ground strength measured by the JB/T8355-96
type test piece is greater than 0.6rm (i.e. 0 center A>, the type test piece should be used to measure the shot peening strength. 3.2 In some special cases where standard height test pieces are not suitable, non-standard size test pieces can be used. Before the comparison, a height comparison test should be conducted between the non-standard size test piece and the standard height test piece, and the shot strength (i.e. gun strength) of the non-standard size test piece when the standard height test piece is used is determined according to the drawing. A4 Determination of shot peening visibility
A4.1 Fasten the standard double height test piece to the clamping die. 4.2 Install the clamping block with the installed test piece on the workpiece carrier, and its position and direction should be consistent with the workpiece being peened. The low position and direction of the light parts of the shot peening workpiece are similar to those of the shot peening workpiece, and they are in the same motion state as the workpiece being shot peened. A4.3 The automatic equipment is used for suction and testing. A4.4 After the specified time (or number of cycles), the batch shot peening is stopped and the test piece is removed. A4.5 Check the extension height of the non-shot peened surface of the test piece on the gauge. The non-shot peened surface of the test piece should face the single head of the gauge. The distance between the center point of the non-shot peening surface of the test piece and the specific basic plane formed by the four ball heads of the gauge is the tension height. A4.6 According to the regulations of A4.1 to A4.5, select a shot peening process and test six or more test pieces according to different extraction times (or times) to obtain a set of data and draw a "strength height-time\ (or number> curve on the coordinate paper. In the case of fully adjusting the equipment within the allowable range of the equipment and updating other process parameters, a series of different "real height-time or number" curves will be obtained in this way,
A4. In order to select the most ideal curve from the obtained "real height-time or number" curves, re-shot peen a test piece with the shot peening process parameters corresponding to the commercial line and the degree, and measure it according to the provisions of A4.1 to A4.5. The fixed result is called gloss loss intensity.16 Determination of the surface roughness of the workpiece after shot peening 4.1. Remove all dust and debris from the surface of the workpiece to be tested during the shot peening process. 4.1.2 Use a shot peening surface roughness comparison sample block with a similar material and roughness to the workpiece to compare with the surface of the workpiece to be tested. When comparing, the comparison sample block should be placed close to a certain area of the workpiece to be tested, and the scratched surface should be compared with four different sections of the comparison sample. The roughness of the workpiece surface can be determined by the actual feeling. 4.1.6.3 During the determination process, the comparison sample block should be placed under the same conditions as the workpiece (such as composition, light, etc.). 4.1i.4 For workpieces with high surface requirements (such as R of 0.2m, 0.44m, 0.8m), a comparison test can be performed by placing the magnifying glass in the space between the test surface and the comparison sample surface: the magnifying glass should not exceed the scope of the magnifying glass.
4, 1.5 If the surface roughness and fineness cannot be measured by comparison sample due to the influence of the surface coverage of the workpiece, a surface roughness test should be performed, and a half-plate of the same specification processed under the same conditions as the test surface should be used for measurement according to the specified conditions. 4.16.6 When there is a dispute over the measurement result, a method with higher accuracy than the above method can be used. The method of determining the high quality shall be as follows. 4.17 For the determination of the shot peening strength of the workpiece after shot peening, see Appendix A (Standard Appendix). 4.18, for the surface of the workpiece after shot peening. Determination of yield 4.18.1 Definition of surface coverage
The ratio between the area occupied by the bullet marks and the area required to be shot peened at a specified position on the surface of the workpiece to be shot peened is called the surface coverage ratio
The surface coverage ratio is expressed as a percentage. When the surface of the workpiece is equal to or less than 2% of the initial surface, the measured surface yield ratio is defined as 100.
4.18.2 On the surface of the workpiece after shot peening, select the measured points and magnify them. A large mirror with a magnification of at least 50 times is used for daily measurement and the original surface area on the sprayed surface is counted: 102cm×102mum or 1C4cm surface! The percentage of the surface area occupied by all interception marks in the model is calculated, and the result is the surface coverage rate. 4.1, 3 If the agreement stipulates a surface coverage rate of more than 100%, the model spraying time is used for calculation. Example: 200 surface coverage rate means that the upper source is sprayed (spraying> time is twice the 10C% surface coverage rate. 7
