Drawings and specification for the punching die

These drawings show a die-cutting stamp. 

The stamp includes:

1. Standard unit. The application allows you to achieve prompt installation and optimal pairing of parts. It includes: plates (upper and lower); tang; guide columns. 

2. Matrix. The lower part of the product, which is fixed motionlessly on the press table. To influence the workpiece, a sharp cutting edge is provided in it.

 3. Die. A moving part that is fixed by a shank in the slider of the press. The diameter of the cutting edge is some amount smaller than the matrix edge. This value is called the gap, and its value should tend to zero or be strictly symmetrical on both protruding sides.

 4. Catcher. It is an emphasis for the advancement of the strip after impact, ensures the uniformity of the process and reliable fixation of the workpiece. 

5. Puller. Removes waste from the punch as it moves upwards. 

6. Guide rulers, fixing bolts and studs.

Principle of operation:

The principle of operation is to feed the sheet rolling billet into the working area of the machine. After that, the rolled product is affected by the punching die due to the pressure exerted on the punch. To separate the part, the cutting edges of the punch and die act on the sheet. At the same time, they deform the surface of the workpiece, compressing it. The punch pushes the cut part into the lower part of the matrix, which has an extension.
