What is punching machine

The purpose of using the link mechanism is to reduce the cycle of the processing while maintaining the stretching speed within the limit during the extension processing and use the reduction of the speed change of the extension processing to speed up the approaching stroke and from the top dead center to the processing start point. The speed of the return stroke from the bottom dead center to the top dead center makes it have a shorter cycle than the crank press to improve productivity.

This type of punch has been used for the deep extension of cylindrical containers since ancient times. The bed surface is narrow, but it is used for the processing of automobile body panels and the bed surface is wide. The characteristic of this kind of punching machine is the cam shape which is made properly, so as to obtain the desired slider moving curve easily. However, due to the nature of the cam mechanism, it is difficult to convey greater force, so the punching capacity is very small.

The stamping process can make these advantages that cannot be achieved by mechanical processing through various mold applications, so its use is becoming more and more widespread. Today I will introduce you to the definition and characteristics of the punch press.

Published: May 11, What is a punch A punch press is a stamping press. Uses and characteristics Punching machines are widely used in the stamping and forming of hardware parts such as electronics, communications, computers, household appliances, furniture, and transportation, such as automobiles, motorcycles, and bicycles.

It has the following characteristics: High-rigidity, high-precision frame, welded with steel plates, and after heat treatment, the internal stress of the fuselage is eliminated, so that the equipment can work stably without deformation for a long time.

A load of structural parts is even and the rigidity is balanced. Stable high precision The main parts of the equipment, such as crankshaft, gear, transmission shaft, etc. Reliable and safe operation performance Because the combined device which is different from the traditional brake has a high sensitivity, coupled with the double electromagnetic control valve and overload protection device commonly used in international high-end equipment, it ensures the accuracy and safety of the high-speed movement and stops of the punch sliders.

Production automation, labor-saving, and high efficiency The punch can be matched with the corresponding automatic feeding device, with feeding error detection, pre-cutting and pre-breaking devices, which can fully realize automatic production, low cost and high efficiency.

Slider adjustment mechanism The quick adjustment is divided into manual adjustment and electric adjustment, which is convenient, reliable, safe and fast, and the accuracy can reach 0. Novel design and environmental protection Using advanced technology and design concepts from Japan, it has the advantages of low noise, low energy consumption and no pollution. Classification of Punch According to the driving power, it can be divided into: 1 Mechanical Power Press 2 Hydraulic Press For ordinary sheet metal stamping, most of them use mechanical punching machines.

According to the slider drive structure, it can be divided into: 1 Crank Press Presses using crankshaft mechanisms are called crankshaft presses. Published: May 11, Source : kknews.

Hydraulic presses have different hydraulic fluids, hydraulic presses, and hydraulic presses. Currently, hydraulic presses are the majority, and hydraulic presses are mostly used for large machinery or special machines. Sort by slider motion:. According to the slider movement mode, there are single-action, double-action, three-action punches, etc.

The double-action and three-action punch are mainly used in the car body and large-scale machining parts. Processing, the number is very small. Classified by body shape. According to the type of fuselage, there are two types: 1 open-back type C 2 straight-column H-type fuselage. At present, the punches used by general stampers are mostly C-type, especially small punches tons. The following is the most, and the mainframe is the mostly straight type H type.

Because the fuselage is not symmetrical, the reaction force during punching will cause deformation of the front and rear openings of the fuselage, resulting in deterioration of the parallelism of the mold, which is the biggest disadvantage. The mold is close to the good, easy to change the mold and other favorable factors, and is still widely loved, and the price of the machine is relatively cheap, which is the mainstream of the current stamping machinery.

The straight-column machine tool is symmetrical because it is symmetrical, and it can withstand the eccentric load during operation. However, the proximity of the mold during operation is poor. Generally, the main machine uses more than tons of punches and has an integrated body and three.

Two types of segmental body. These machines are usually equipped with a linear matrix carrier tool holders and quick change tools. The numerical computerized punching CNC is a manufacturing process of sheet metal that is made by CNC punching machines.

These machines can be a single head design and tool rail or turret design of multiple tools. A punching machine works like a paper drill.

The punch presses the paper against the drilling stand and finally into a round opening.
