There are many stamped parts in various instruments, household appliances, bicycles, office machinery, domestic utensils, and other products. Parts that are stamped play a significant role in our daily lives. For example, stamping parts include automobile bodies, chassis, radiator plates, boiler drums, container shells, iron cores, silicon steel sheets for motors, and electric appliances. The production and processing of precision stamping parts requires attention to a number of factors. Metal stamping parts have different operating requirements, including images, sizes, and stamping dies.
What is the purpose of stamping parts?
By using the press and die, the stamped part is formed and processed by applying external force to the plate, strip, pipe, and profile. This produces plastic deformation to obtain the work piece with the desired shape and size. As a plastic processing (or pressure processing) process, stamping is also referred to as forging. Blanks are generally made of hot-rolled and cold-rolled steel.
Stamping parts: critical points
1. To improve the safety and reliability of production, improve the processing equipment for Sheet Metal Fabrication. Old hardware stamping equipment has many safety risks. To ensure the safety and reliability of stamping equipment, the stamping equipment manufacturer must improve its product design. If we use them continuously, we have to reform them technically.
2. The processing technology, mold, and operation mode of metal stamping parts realize manual operation outside the mold. We can start with reforming the process and mold for mass production to realize mechanization and automation.
3. Install the guard. Due to the small production volume, safety protection devices must be installed in the stamping operation. It cannot automate the process nor use safe stamping tools to prevent injury accidents caused by errors in operation. There are different characteristics and applications of different kinds of protective devices, so injuries may still occur if they are not used properly. In order to ensure correct use and safe operation while processing metal stamping parts, it is necessary to understand the role of protection devices.
Controlling stamping accuracy
Blanking clearance, die manufacturing accuracy, material properties, thickness, shape, and size of stamping parts are all factors that influence accuracy. Blanking clearance is the main factor. The material will be subjected to a significant drawing effect during blanking if the gap between the male and female dies is too large. The drawing deformation will be very significant.
A metal stamping part's surface quality should not exceed its raw material surface quality in principle. The cost of stamping parts will also increase if further processes need to be added during processing. Dimensional accuracy can be classified into precision and ordinary levels, based on the dimensional error and surface quality.
The precision achieved by stamping metal parts in various grades is the precision achieved by stamping technology. In contrast, ordinary grade metal stamping parts are the more economically feasible form of precision. When the mold manufacturing accuracy is high, the overall dimension accuracy of the metal stamping parts can reach itl0 level, and the inner hole size can reach it9 level. A stamped part's dimensional accuracy depends heavily on the manufacturing accuracy of the mold.
Stamping method for forming parts
The metal stamping parts are the forming and processing method of the work piece (metal stamping parts) with the required shape and size by applying an external force to the plate, strip, pipe, and profile by using a press and die to produce plastic deformation or separation. Press and die apply external forces to plates, strips, pipes, and profiles in metal stamping.
The forming process of the work piece (metal stamping part) with the required shape and size is done by plastic deformation or separation. Stamping and forging belong to plastic processing (or pressure processing) and are collectively referred to as forging. Stamping blanks are mainly hot-rolled and cold-rolled steel plates and strips. Stamping is primarily classified by process and can be divided into separation and forming. Get more info about Aluminium Custom Fabrications.
From the above introduction, we can see the precautions for stamping parts processing. Of course, maintenance and repair of stamping parts are also essential to work. The primary intention to ensure the quality of precision stamping parts is to pay attention to the maintenance and repair of stamping lathes and stamping dies to produce qualified precision stamping parts.
