Technology Repair measures

Technology Repair measures 

 The main technological measures to adjust the gap between two kinds of the mould method:

 1. Size method 

 Processing of the punch, will the punch front-end appropriate lengthen, extended period of section size and sunken model hole processing to the same size. Assembly, Precision stamping parts make the punch into female model hole, natural form the cutting clearance, and then to the punch with fixed together with the punch mould seat on board with the pin for fixed and will last longer period of the punch front can remove form even clearance. 

2. Positioning hole method

  Process positioning hole method and the inside of the progressive die principle about. Processing, the punch in fixed board and concave die on the same position processing two positioning hole, can will locate hole and the mold cavity a cut out. Assembly, in the positioning hole insert pins to ensure that gap.

Standard model method  

According to the drawing wedm in advance in processing a standard model or the qualified stamping parts, to adjust the assembly put it in between convex,Precision stamping partsconcave die, upper and lower die relative motion can be reasonable degree when appropriate.  

 Measurement method  

Measuring method of the measuring tool have feeler. A feeler method after the adjustment convex, concave die clearance good uniformity, it is the commonly used method. Assembly, the punch in the concave die in the hole, convex, concave die according to the size of the clearance choose different specifications of the feeler insert convex, concave die clearance, Precision stamping partsinspection concave die around the blade gap everywhere, and according to the measured results adjustment. If the adjustment of the punch fixed board knock until adjust good so far.
