How to test the performance of precision punching machine?

1. Tonnage test of precision punching machine
This test needs to be tested with a punch tonnage tester, which can accurately measure the actual pressure of the punch.

2. Test of precision punch precision
The accuracy test of the precision punching machine needs to detect the parallelism between the bottom surface of the slider and the lower table, the parallelism, the verticality, the total gap between the upper and lower sides of the motion mechanism, and the noise value of the machine. The accuracy detection value should conform to J.I.S (Japanese Industrial Standard) first-class precision standard.

3. Dynamic balance test of flywheel
The dynamic balance test of the flywheel of the precision precision punching machine is determined by the two-point method, that is, a test method in which the vibration amplitude of the punching machine is reduced to a specified range by means of balance correction at the working speed. The amplitude of the precision punching machine is required to be controlled at around 0.02mm, usually the test value is around 0.015-0.02ram so as to fully meet the needs of customers.

4. Coordination test of clutch and brake
This test is carried out after the assembly of the precision press clutch and brake is completed. The inspection method is very simple, that is, to check whether the brake is fully opened when the clutch is connected; whether the clutch is disengaged when the brake is applied. Although the inspection is simple, it is indispensable. It directly affects the accuracy of the start and stop of the slider, and directly affects the safety of stamping production.

5. Test of rigidity of precision punching machine

The rigidity test of the precision punching machine is usually carried out after the installation and commissioning stage of the customer's site is completed, mainly to test the two aspects of the workbench and the slider. Combined with the method, the obtained measurement data is listed and the curve is drawn, and compared with the standard value to see if it is consistent.
