(1) the crankshaft organization is often used the most, because the production and manufacturing is very easy, high-speed precision punch manufacturers can properly clear the lower part of the travel arrangement, the theme of the slide activity diagram for a variety of production and processing is most useful.

(2) No crankshaft opening. Non-crankshaft punch is also called shaft force drive gear punch. For the action measurement of crankshaft punch and shaft force transmission gear punch, the shaft bending stiffness, wetting, appearance and maintenance of the shaft force transmission gear punch are better than the crankshaft punch, the defect is that the price is higher.

(3) rotating punch. In the gantry press manufacturer's slider driver, the application of rotary tissue is called a rotary punch, which has a distinctive slider theme movement curve, near the BDC the slide speed will be very slow (compared to the crankshaft punch). And the appropriate arrangement of the bottom dead center position, so the punch is suitable for stamping parts processing, deep processing and other narrowing production processing, cold forging is now the most used number.

(4) friction punch. Selection of friction drive system and rail drive system screw type organization of automatic punching machine called friction automatic punching machine. It has the function of intelligence, and because of its high quality and low price, it has gained widespread use.

(5) before, it is used to extrude the bushing, extrude the debris and other objects, extrude the oil, bind and extrude the casing (to carry out the thinning solution in the hot chamber), etc. , but now has long been changed to the hydraulic press, except for the very unique situation, has long been not needed.

(6) The purpose of the application of mechanical structure is to reduce the production and processing cycle time, and to maintain the drawdown rate within a limited scope during the drawdown production process. According to the speed change of the pull-out production and processing, the speed of the close stroke arrangement from the upper dead point to the starting point of the production and processing and the rate of the round trip from the bottom dead point to the dead point are accelerated, which makes the cycle time shorter than that of the crankshaft punch press and improves the production efficiency.

(7) this kind of automatic punch is characterized by exquisite camshaft appearance, and it is very easy to get the required slider theme activity curve. However, because of the nature of the CAM mechanism, it is difficult to deliver very high compressive strength, so the volume of this type of press is not large.
