Sheet metal parts are metal parts that have been processed or machined. Metal raw materials are usually used, which are plastically deformed by process or stamping, and the shape formed usually meets the requirements of our rules. Molding can be divided into manual molding and mechanical molding. Process molding is usually used to make up for processing or trimming areas, rarely used. But in the processing of some of the shape of the messy or easy deformation of the material, or can not be separated from the process of molding.

So far, sheet metal processing is mainly used to manufacture the shell of some packaging equipment, such as cabinets, car bodies, stainless steel cases, computer cases, etc. Because sheet metal includes stamping, bending, shearing and cutting, most of the sheet metal is processed by sheet metal, and a small amount of sheet metal is used for manufacturing.

Classification and processing of sheet metal parts

Sheet metal parts can usually be divided into three categories:

1. Flat plate: refers to ordinary flat stamping shear parts.

2. zigzag type: according to the planning drawing with CAD after opening, bending and welding.

3. Forming type: regular curved surface or free-standing curved surface parts processed by stretching and other forming methods. These parts are made of flat blank stamping and deformation, which is very different from the parts processed by the usual machining method. In the stamping processing method, the tortuous deformation is the main processing method to make the sheet metal parts have disordered spatial position relationship.

II. The scope of application of sheet metal processing:

Sheet metal parts are widely used in electromechanical, light industry, automotive and other fields. Specifically include the following aspects:

1. Automotive field

With the progress of Chinese people's living standards, cars will enter thousands of households, which will promote the rapid development of the domestic automobile field. Automobile manufacturers will outsource non-base business while expanding their production plans, so they will outsource some automobile parts to Hefei sheet metal processing plant, which will supply, distribute and process automobile fields.

2. The field of electronic communications

The electronic field is a field that has developed rapidly in recent years, and it is also a field where sheet metal was widely used at that time. Due to the characteristics of fast technology update, product diversity and timely production in this field, this field is facing a greater risk impact from shopping malls. Most of the well-known companies at home and abroad have outsourced the sheet metal business and used limited funds for technology development. These companies include: Lucent, Bell, ABB, Nokia, Siemens, Alstom, Philips and Huawei, among others., And their outsourced sheet metal processing business is worth tens of billions of dollars a year.

3. Elevator field

The elevator parts in the field are mostly sheet metal parts, and the types of elevator parts are complex. Each large elevator manufacturer has dozens of suppliers to distribute and process them. For example, famous elevator companies such as Otis, Schindler, Mitsubishi, Hyundai and Hitachi all have their own stable suppliers, and their outsourced sheet metal business in Guangzhou is about several billion yuan.
