Punch and dies product height NG problem and causes

 Punch and dies product height NG reasons:

– The closing height of the die is less than the closing height of the punch;
– The height of the limited height of the mold is greater than the height of the product;
– Hold time setting is too short;
– Hydraulic press tonnage selection is too small, punch stroke is small;
– The stroke switch position of the hydraulic press is set too high, and the pressure is set too small;
– Hydraulic system failure, the pressure is not up to enough strength.
Recommended handling method:
– Thickening the die pad, the die closing height is greater than the closing height of the punch, and then adjust the stroke switch position;
– Reduce the mold height limit pad to the required height of the product;
– Adjust the holding time according to product plasticity requirements;
– Choose hydraulic presses with larger tonnage and stroke;
– Adjust the switch and pressure of the fast stroke of the hydraulic press as required;
– Clean the filter screen of the hydraulic pump inlet, add hydraulic oil to the standard level, repair or replace the hydraulic pump.
