The smooth implementation of the stamping process can not be separated from the support of various types of specialized equipment, these equipment according to the different processing needs, there are two main categories.

a. Shearing machine

Shearing machine is a shearing method to make the plate separation of stamping equipment.

Material with equipment, the plate will be cut into a certain width of the strip for stamping according to the form of transmission is divided into mechanical shears and hydraulic shears.

b. Presses

Press is a slide can make reciprocating motion, and according to the required direction to the mold pressure machine, is the basic equipment for stamping. According to its bed structure has different open and closed two kinds of presses.

Press to use millions and thousands to pay attention to safety! Mechanical presses: crank presses, linkage presses, cam presses, thread presses and so on. Hydraulic presses use oil pressure, and pneumatic presses use air pressure. The use of human power to complete the foot stamping machine (commonly known as: a foot kick), manual stamping machine and other types.

The following is a detailed description of the various types of stamping equipment

1. Mechanical press

This is the most widely used stamping equipment, through the crank linkage mechanism will be the rotary motion of the motor into the linear reciprocating motion of the slide. According to the tonnage can be divided into small (≤ 1,000kN), medium (1,000 – 3,000kN) and large (≥ 3,000kN), small machine is suitable for electronic components, small hardware stamping, large machine is used for automotive coverings and other large workpiece processing. It is characterized by stable operation and high efficiency, and the number of stamping times per minute can reach 10 – 200 times, which can meet the demand of mass production.

2. Hydraulic press

relies on hydraulic transmission to drive the movement of the ram, which has the advantages of large pressure and wide speed range, and the tonnage can be as high as tens of thousands of tons, which is suitable for the processing of thick plates, large and complex parts and materials with poor plasticity (such as high-strength steel plates). Hydraulic press pressure can be kept constant, in the tensile, bending and other molding processes, outstanding performance, especially for precision stamping and multi-station composite processing, but its operating speed relative to the mechanical press is slower.

3. pneumatic press

with compressed air as the power source, simple structure, convenient operation, tonnage is generally small (≤ 500kN), mostly used for small parts punching, drop, bending and other simple stamping processes. Because of its low cost and easy maintenance, it is often used for small batch production or laboratory prototyping, and with low noise, it is suitable for scenarios with high requirements on the working environment.

4. High-speed press

is specially designed for high-efficiency and high-precision stamping, with the number of stampings per minute reaching 300 – 2000, mainly used for processing of miniature parts in electronics and instrumentation industries, such as cell phone connectors and IC lead frames, etc. The machine is equipped with a high-precision guiding mechanism and an integrated circuit lead frame. The equipment adopts high-precision guiding mechanism and dynamic balance design, which can ensure the stability of high-speed operation and ensure the consistency of product size.

5. Multi-station press

integrates several stamping processes into one production line, and transfers workpieces between different stations through an automatic feeding mechanism to realize continuous processing of drop, punching, bending, stretching and other processes. This kind of equipment has a high degree of automation, reduces the workpiece handling time, and increases the production efficiency by more than 50% compared with the single station equipment, which is widely used in mass production scenarios such as automotive parts and household appliance shells.

6. CNC Stamping Press

Combined with computer numerical control (CNC) technology, it can be programmed to realize automatic die change, positioning and stamping, with high flexibility to quickly switch the production of different products, which is suitable for small batch and multi-species stamping needs. It is equipped with a turret tool magazine can be loaded with a variety of molds, can complete the punching, molding and other complex processing, widely used in the sheet metal processing industry.

In addition, stamping production requires the assistance of supporting equipment, such as uncoiler (for unrolling and leveling the coil and feeding the material), leveler (for correcting material deformation), feeder (for accurately controlling the material feeding speed and distance), and die storage racks (for storing and managing the stamping dies), etc. Together, these equipments form a complete stamping production system, ensuring the process to be efficiently and stably operated.
