Precision equipment load noise really annoying

Precision equipment load noise really annoying The causes of load operation noise are caused by tool and workpiece or stripper plate and blank impact hole punch, stamping process of twisting and punching. One punch stamping process of punching and torsional noise is the biggest noise.

1. Punching shear noise. Stamping process different, very different noise. Sheet blanking than bending, deep drawing noise. The punch press, pressure wave, flanging, bending, drawing and other forming process noise is small.

2. Punch noise. Torsional noise of the same punch press and punch parts thickness punch 360a2, hardness, geometry, hammering speed, die clearance and other factors, noise increases with increasing the amount of these values. Punch work, the punch and the plate and the discharge plate and blank impact impact greatly enhanced, with the impact of the impact speed also increased. The collision noise of the punch and the subsequent fracture sound of the material can be measured separately, and this measurement method has been implemented punch update. In the same punch, punching thick, hard material than the punching thin, soft material noise. For thick ductile sheets, the impact noise is the same as the fracture sound.
