Stamping is a forming method that releases external force on the plate, strip, pipe fittings and profiles by the bed and die to cause plastic deformation or separation, and then obtain the required appearance and specification of the product workpiece. It is commonly used in the stamping and forming of mechanical, computer, electrical appliances, furniture and other hardware parts. The stamping drawing process should be selected and designed according to the actual situation of equipment and personnel, which is advanced in technology, effective in economic development, safe and reliable in application. What are the features of the punch press：

1、 Characteristics of new punch press equipment

(1) The high rigidity and high precision frame of punching machine is welded with thick steel plate, and the load and rigidity of structural parts are balanced. After heat treatment, the technetium thermal stress of the shell is removed to make the equipment stable and stable for a long time.

(2) The key components of punch machine, such as crankshaft, gear and transmission shaft, are hardened and heat treated, which has high wear resistance and stable long-term performance, which ensures high precision and stability.

(3) Due to the selection of different from the traditional brake, the combination of clutch and brake has high sensitivity. In addition, the overload protection device ensures the accuracy and safety of the high-speed movement and termination of the press slider.

(4) Punch equipment can be matched with relative automatic feeding equipment, with feeding error inspection, pre cutting, pre breaking equipment, can completely complete automation.

(5) The advanced technology and design concept of punch press equipment have the advantages of low noise, energy saving and pollution-free, and are convenient, safe and accurate.

2、 Common problems of punch press equipment

(1) The hot crankshaft bearing is caused by poor scraping of the shaft sleeve and poor lubrication. It is necessary to scrape and grind the copper bush again to check the lubrication condition of the crankshaft.

(2) The main reason for bearing debris is the lack of lubricating oil or the lubricating oil is not cleaned. The lubrication condition should be checked immediately and the bearing should be disassembled for cleaning.

(3) The causes of rail burning include too small clearance, poor lubrication and poor contact. It is necessary to scrape the guide rail again, adjust the clearance and pay attention to the lubrication condition.

(4) When the clutch is not engaged or cannot be disengaged after the clutch is engaged, it is necessary to park and replace the spring, replace the brake and grind the clearance of the key.

(5) The reason for the rotation or impact of connecting rod screw is that the ball cage and the ball cushion cover are not in good contact. Check and scrape the ball cage, ball cushion and tighten the gland screw.

(6) Press the button, the reason why the press does not start is short circuit of power supply, power failure of thermal breaker, etc.

3、 Selection of fine stamping oil

(1) Because silicon steel plate is easy to be sheared and pressed, low viscosity stamping oil can be selected for easy cleaning of finished products and avoiding shearing and pressing burr.

(2) The viscosity of drawing oil should be paid attention to when selecting stamping oil when carbon steel sheet stamping. The optimal viscosity is determined according to the process difficulty, oil feeding mode and deoiling standard.

(3) Due to the chemical reaction with chlorine additives, it is necessary to pay attention to the problem that chlorine type stamping oil may produce white rust when selecting stamping oil for galvanized steel sheet.

(4) Stainless steel is easy to cause stamping hardening material. It is required to use drawing oil with high floating oil strength and good sintering resistance. Generally, stamping oil with sulfur and chlorine compound additive is used to ensure extreme pressure processing performance and prevent product parts from burring and cracking.

The above is the technical advantages of punch equipment and solutions to common problems. Reasonable process arrangement, application of special stamping oil and selection of reliable raw materials can reasonably improve product quality.
