Electrical appliances stamping parts blanking deformation is why?
Appliances stamping forming bending in many applications need to be, but at the time of production will be easy to deformation, today small authors and everyone together to analyze the causes of: electrical appliances stamping parts in clearance action and reaction is not a level to produce torque, (
Intensive clearance is too large and the blade with the concave mould taper, or ejection device and stamping deformation contact area is too small)
When we are in the production of how to solve?
At first, we promise to reasonable appliances stamping parts blanking clearance, should increase the pressure on the mould structure plate (
Or retainer plate)
Contact with the pressure plate surface has a certain pressure, check mold edge reverse taper die must be found to nap, such as stamping parts are too many complicated shape and inner hole, the punching sheet needs to be before leveling, and at the same time with high precision blanking press, remove dirt from the mould cavity regularly, tong oil and gas hole is set on the die structure.
