What should be paid attention to in mold debugging of precision metal stamping-hardware

Precision metal stamping will be tested and debugged before production, especially for new molds. Be careful when trying out molds. The performance of the mold is still unknown at this time, and it is also unknown where there will be a problem. So what should be paid attention to when testing and adjusting the mold? Xiaoshuo shares a few points with you. After the punch workbench is cleaned up, the mold to be tested in the clamping state is placed in a suitable position on the workbench. The stroke of the press slider selected according to the process documents and the design requirements of the die is adjusted to the bottom dead center before the die is moved onto the stage, and is 10-15mm greater than the closed height of the die; adjust the slider connecting rod, move the die, and ensure the die The handle is aligned with the hole of the mold handle and reaches the proper height of the mold. Generally, the blanking die first fixes the lower die (not tightened) and then fixes the upper die (tighten). T-bolts of the pressure plate should be tightened with a suitable torque wrench (lower die) to ensure that the same bolts have a consistent and ideal pre-clamping Tightening force can effectively prevent the pre-tightening force caused by physical strength, gender, and feel errors caused by manual tightening of the thread from being too large or too small, and the same thread pre-tightening force is unequal, which will cause the upper and lower molds to move, gap changes, and Failures such as gnawing and peeling edges occurred. Before the mold test, fully lubricate the mold and prepare the normal production materials. Start the punching mold 3 to 5 times in the idle stroke, and then try the punching after confirming that the mold is operating normally. Adjust and control the depth of the punch into the die, check and verify the performance and operational flexibility of mechanisms and devices such as die guide, feeding, pushing and unloading, side pressure and elastic pressure, and then make appropriate adjustments to achieve the best technical state. Test 3, 5, and 10 pieces of large, medium and small dies respectively, and conduct preliminary inspections for suspension of production, and then try to punch 10, 15, and 30 pieces for re-inspection after passing the test. After scribing inspection, punching surface and burr inspection, all dimensions and shape and position accuracy meet the requirements of the drawings, before they can be delivered to production.
