There are many stamping parts in various instruments, household appliances, bicycles, office machinery, domestic utensils, and other products. Stamping parts plays a vital role in our life. The stamping parts include the automobile body, chassis, oil tank, radiator plate, boiler drum, container shell, iron core, silicon steel sheet of motor, and electric appliance. There are many things to pay attention to for the production and processing of precision stamping parts. There are different operating requirements, from producing metal stamping parts to the product image, size, and stamping dies.
What is a stamping part?
The stamping part is a forming and processing method that applies external force to the plate, strip, pipe, and profile by the press and die to produce plastic deformation to obtain the workpiece with the required shape and size. Stamping belongs to plastic processing (or pressure processing), referred to as forging. The stamping blanks are mainly hot-rolled and cold-rolled steel plates and strips.
Critical points of the stamping parts process
1. To improve the safety and reliability of production, improve the processing equipment of metal stamping parts. Many unsafe factors exist in old hardware stamping equipment. If we are continuously using them, we have to reform them technically. The stamping equipment manufacturer will have to improve the product design to ensure the safety and reliability of the stamping equipment.
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, install safety protection devices in the stamping operation. It can neither realize automation nor use safe stamping tools to prevent injury accidents caused by operation errors. All kinds of protective devices have different characteristics and use ranges. Injury accidents will still occur if they are not used properly. Therefore, it’s necessary to understand the role of protection devices to ensure correct use and safe operation while processing metal stamping parts.
How to control the stamping accuracy of stamping parts
Many factors influence accuracy, such as blanking clearance, die manufacturing accuracy, material properties, thickness, shape, and size of stamping parts. The main factor is blanking clearance. When the gap between male and female dies is too large, the material will be subjected to a significant drawing effect during blanking so that the drawing deformation will be enormous.
In principle, the surface quality of metal stamping parts should not be higher than the surface quality of its raw materials. Otherwise, subsequent processes must be added during processing, which will also increase the production cost of stamping parts. It’s judged from the dimensional error and surface quality. The dimensional accuracy of metal stamping parts can be divided into precision and ordinary levels.
Precision stamping of metal parts in different grades is the precision achieved by stamping technology. While ordinary grade metal stamping parts are the precision that can be achieved more economically. 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. It can be seen that the manufacturing accuracy of the mold is the decisive factor in the dimensional accuracy of the stamping parts.
Forming method of stamping parts
The metal stamping parts are the forming and processing method of the workpiece (metal stamping parts) with the required shape and size by applying an external force to the plate, strip, pipe, and profile by the press and die to produce a plastic deformation or separation. The metal stamping parts are the external force applied to the plate, strip, pipe, and profile by the press and die.
The forming process of the workpiece (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. The 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.
The Bottom Line
From the above introduction, we can see the precautions for stamping parts processing. Of course, the 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.
