——“Samhoor nicety machine”it began in 2000 year,focus on Precision punching, high-speed presses production stamping equipment R & D .
Dedicated, professional, quality !
The main reason for C-type high-speed presses punch wear too fast
1, punch temperature is too high, mainly due to the same cause mold continuous long high-speed stamping punch overheating.
2, high-speed presses mold improper sharpening, resulting in mold annealing, increased wear.
3, punch and die neutral bad, including mold base and mold guide assembly and inadequate turret casement precision mold and other causes on neutral bad.
4, mold gap is too small, the general recommendation 20% to 25% of the total thickness of the die gap of the material.
5, partial unilateral punching, such as nibbling, when the angle of attack, or shear, lateral forces will punch one side, the side of the gap is reduced, resulting in mold wear serious, if high-speed presses mold mounting accuracy is not high severe migraine will punch through the die, resulting in damage to the punch and die.
