Punch Press Classification with Slider Drive Mechanism in the Punching Process

The design principle of the punch press is to change the circular motion to a linear motion. Punching by pressing the ingredients, causes them to change shape. Therefore, a set of molds must be used to achieve the desired shape and precision. The material is placed between them and deformed by the pressure exerted by the punch press machine.

In the punching process, there are several classifications of punch press. The following is a slider drive mechanism that is often used, including:

1. Rack Press
   The use of a rack and pinion mechanism on the slide drive mechanism is called a rack-and-pinion press. Screw presses have almost the same characteristics as rack and pinion presses, and more or less the same characteristics as hydraulic presses. Previously, it was used for extrusion of pressed liners, scrap and other articles. However, rack press has now been replaced by hydraulic presses and is no longer used except in very special circumstances.

2. Knuckle Press
   The use of the elbow joint mechanism in the sliding drive is called a knuckle press. This type of punch press has a unique slider motion curve where the speed of the slider gets very slow near the bottom die centre. Therefore, this press is suitable for compression processing such as stamping and finishing and is therefore most often used in cold forging processes.

3. Link Press
   Punch presses that use multiple linkage mechanisms on a sliding drive mechanism are called linkage presses. The purpose of using the linkage mechanism is to shorten the cycle time while keeping the drawing speed within limits during the drawing process

4. Cam Press
   Punching machines that use a slide drive mechanism are called cam presses. This type of press is characterized by making a suitable cam shape so that the desired slide drive profile can be easily obtained. However, due to the nature of this mechanism it is difficult to transmit a large force, so this type of press has a very small capacity.
