Vulcanizers should meet the requirements specified in this standard and be manufactured in accordance with the drawings and technical documents approved by the prescribed procedures. 4.1 The vulcanizer should have manual and automatic control systems, and can complete the process of loading, vulcanizing, unloading products, etc. 4.2 The vulcanizer should have a device to indicate and adjust the clamping force. 31500
4.3 The vulcanizer should have instruments that indicate or record the external temperature, internal temperature and can adjust the external temperature. All instruments should work sensitively, safely and reliably. 4.4 When the clamping force of the vulcanizer reaches the maximum value, the oil pump stops working and maintains the pressure for 1 hour. The pressure drop of the hydraulic system shall not exceed 10% of the nominal pressure.
4.5 When the pressure drop of the hydraulic system exceeds 10% of the nominal pressure, the hydraulic pump shall be able to automatically start to replenish the pressure until the nominal pressure is reached.
The working fluid pressure of the hydraulic system shall be adjustable within the range of 60% to 100% of the nominal pressure. 4.6
4.7 The hydraulic cylinder must be subjected to a pressure resistance test of 1.5 times the nominal pressure, and the pressure shall be maintained for 5 minutes without leakage. 4.8 The surface roughness of the working surface of the hydraulic cylinder, piston (plunger) and piston rod shall be Ra≤1.6μm. 4.9 There should be a heat insulation layer between the bowl-shaped capsule mold and the upper and lower workbenches, and between the upper and lower workbenches and the upper crossbeam and the bottom plate of the workbench. 4.10 The flatness of the working surface of the upper and lower workbenches should comply with the provisions of the 9th grade tolerance value in Appendix 1 of GB1184; the flatness should comply with the provisions of the 8th grade tolerance value in Appendix 3 of GB1184: 4.11

4.13 The appearance quality of the vulcanizer shall comply with the provisions of HG5--1541. 4.14 The painting quality of the vulcanizer shall comply with the provisions of ZBG95010. 5 Safety Requirements
5.1 The vulcanizer must be equipped with an emergency switch. 5.2 The hydraulic system should have a reliable pressure limiting device, 5.3 The vulcanizer should have a safety control device that automatically cuts off the power supply of the oil pump motor when the clamping force exceeds the maximum value, 5.4 The noise sound pressure level of the vulcanizer during operation shall not be greater than 85dB (A), 5.5 The whole vulcanizer or heavy parts should be easy to hoist. 6 Test method
6.1 Idle operation test
6.1.1 Before the idle operation test, the following items should be checked: a.
The measurement of the workbench size and spacing should comply with the provisions of Table 1; the detection of the surface roughness of the hydraulic piston, piston (plunger) and piston rod should comply with the provisions of Article 4.8; b.
The detection of the flatness and parallelism of the workbench should comply with the provisions of Article 4.10; c
d. Check the coaxiality of the upper and lower core mold positioning flanges as follows: The upper and lower core mold piston rods extend to the limit position, and the power cylinder piston (plunger) rises, so that the distance between the lower core mold flange and the upper core mold flange is 10mm. Measure the offset of the outer circle of the center of the upper core mold flange to the outer circle of the center of the lower core mold flange, and the maximum value of the offset. That is, the coaxiality error value, should comply with the provisions of Table 2. The number of opening and closing of the mold in the dry operation test shall not be less than 5 times, and check the following items: 6.1.2
Check the accuracy and reliability of the control system according to the requirements of Article 4.1; check the emergency switch according to the requirements of Article 5.1. It should be sensitive and reliable; b.
Measure the piston (plunger) stroke and the upper and lower core mold piston stroke. It should comply with the provisions of Table 1: c
Detect the piston (plunger) running speed, the method is as follows: d
After the mold opening (piston descending) or mold closing (piston rising) action is normal, measure the full stroke distance of the lower workbench and the time required, repeat the measurement and calculation three times, and take the average value, which should comply with the provisions of Table 1, and count the distance The initial and terminal sections of the movement should be discarded (both are about 1/10 of the movement distance); determine the clamping force as follows:
Use an electric contact pressure gauge with an accuracy of not less than grade 1.5 to measure the pressure of the working fluid and multiply it by the pressure-bearing area of ​​the piston. The resulting value shall not be less than 98% of the value specified in Table 1;
Check that the pressure holding performance of the hydraulic system complies with the provisions of Article 4.4; f
Check that the working reliability of the hydraulic pump complies with the provisions of Article 4.5; The pressure adjustment range of the hydraulic system complies with the provisions of Article 4.6; h.
The pressure performance of the hydraulic cylinder shall comply with the provisions of Article 4.7. 6.2 Load operation test
6.2.1 The load operation test can only be carried out after the idling test is passed. 6.2.2
Load operation test Check the following items:
Check that the mold closing pressurization time (i.e. the time required for the pressure to rise to the maximum pressure after the mold closing) should comply with the provisions of Table 1; Check that each instrument should comply with the provisions of Articles 4.2 and 4.3; The sound pressure level of noise during operation should comply with the provisions of Article 5.4.
