When accepting machine tools according to this standard, it is necessary to meet the requirements of At the same time, the rest of the products that have not been standardized in the CB9061.7.BlT50008.1.ZBn.50008.3 and other standards shall be inspected. 4 Accessories and tools
Should be supplied with the following items:
s) Make a pressure seal:
? Knife-type slide plate brake cover wrench,
) Tool holder rotation and ear wrench
d) - Move the upper piece with a push-f:
F Adjust the stroke block with a push-hand:
More) Check the bed guide rails for special inspection: ) Install the machine tool with adjustment pads, foot guns, washers, explosion drivers; Lubrication for newness:
5 Safety and Health
5! The edge correction of the material should be as follows: the following safety protection devices and electrical connection devices are required (National Machinery Industry Standard 1998-12-01 Implementation JB/T 8770.2—1998) When the calendering is completed, the main drive box should stop working; b) When the lubrication system fails, the gearbox should be turned to check the stopping performance;) The limit travel switch should work properly: l》When the travel switch fails, the main transmission box disengages the gear and slides, and the buffer should play a role in level impact safety protection: e) Before cutting, the main transmission box moves to the farthest, and the left and right frames should be pushed together. When it returns to the left (right) before the stroke, the gears should be picked up. Before the stroke starts, the knife should be lowered and the feeding should be completed: f) The electrical equipment of the machine tool should comply with the relevant provisions of GB/T5226.1, and the line should use a safe contact line 5.2 Noise
5.21 There should be no abnormal sound and impact sound during the operation of the machine tool. 5.2.2 When the machine tool is running idle, measure the noise level of the machine tool according to the method specified in GB/T16769. Under the condition of safe use, the measurement result of the machine tool belt machine should not exceed BA.
5.3 Within the working range, the operating force of the hand wheel and the hand wheel shall not exceed the requirements of Table 1. Table 1
Speed ​​change flat wheel, hand wheel
Tingqi small hand wheel
6 Processing and matching kitchen plate
6.1 The body must be aged after processing. 2 The guide rail pair of the main transmission box and the bed guide rail is an important guide rail, and wear-resistant materials should be adopted. 3 The following joint surfaces should meet the requirements of "fixed joint surface": a) Joint surface of the combined body:
b Joint surface of the gear and the bed
c! The joint surface between the bed and the bed body, the joint surface between the crossbar and the column, and the joint surface between the crossbar and the column should be tightly fitted. When checking with a 1.4 mm feeler gauge within the 1 mm range near the fastening screw, the feeler gauge should not be inserted; when checking with a 0.8 mm feeler gauge outside the 100 mm range, the feeler gauge should not be inserted. 6.4 The contact length of the positioning pin of the spliced ​​bed teeth shall not be less than 60% of the length of the positioning pin, and shall be on both sides of the key. 6.5 Check the degree of clearance according to the provisions of ZBJ5HI3. 6.5.1 The internal activity of the main transmission box and the tool holder feed range shall be sampled and inspected by the single-disc method. The impurity and dirt content shall not exceed O:E (unique).
6.5.2 The cleanliness of the oil in the pressure system shall be sampled and inspected by the repetition method. The impurity and dirt content shall not exceed 4CLg/L (extracted). Machine tool idle operation test
7.1 The main transmission box of the machine shall be tested for low and high speed air operation in the full stroke, and the running time shall not be less than i1.7.2 The accuracy test of the vertical feed plate of the tool holder shall comply with the provisions of the design documents. 8. Load test of machine tools
8. Load test of machine tools should be carried out:
) Maximum cutting test of machine tools:
6, the machine does not have excessive cutting force in a short time. The machine is allowed to keep 2% of the maximum cutting force before the knife is under the condition of positive belt. The maximum cutting force and short time 1B/T8770.2-1998
excessive cutting force should be tested regularly. 8.3 Load test should be carried out according to the provisions of the production documents. During the load test, the mechanism of the machine tool should work positively: Machine condition inspection
Machine tool accuracy inspection should be carried out according to IB/TB770.1 reverse 3
