What do you think are the importance of proper designing of punch plates?

Punch plates range from small simple blocks for holding single piercing punches to large, precision- machined plates for holding hundreds of perforators. Important design considerations include: Adequate thickness for proper punch support. Good doweling practice to insure accurate location.

What is a punch plate?

Punch plate, also known as punched plate and additionally perforated metal, is sheet metal that has been stamped or punched to create a pattern of holes, slots, or decorative shapes. In addition, punch plate is known as perforated metal or perforated screen.

What is the use of punch plate?

Punch Plate are manufactured using solid steel sheets which are than perforated using CNC machinery to create perforate sheets of metal which are than fabricated into a finished product. Punch Plate or perforated screens are fitted into machines used in both the quarrying and recycling sector.

How are punch plates made for one punch?

A punch plate for holding a single punch (Figure 10.1) is made square and with sufficient thickness for good punch support. Two socket cap screws, applied at the corners, resist stripping pressure, while dowels at the other two corners provide accurate location.

How is a punch fitted into a hole?

In the fixed stripper structure, the position and the verticality of the punch is provided by the punch plate. In this method, the punch is lightly press-fitted into a hole in the punch plate. Light press-fitting is driving the punch inside the hole by hitting it lightly.

What kind of forces are involved in punching?

During the punching process, the punch encounters both compressive and tensile forces. As the punch contacts the surface of the material being punched, the punch tip applies pressure to the workpiece until it overcomes the material’s tensile strength.

What are cutting clearances between Punch and die?

Cutting clearances between the punch and die are closely defined and specified in the die design stage, based on the requirement of the part. This stamping process produces a very predictable edge condition on the finished part.
