Sheet metal parts refer to metal parts that have been processed by technology or machinery. Metal materials are usually used to produce plastic deformation through technology or stamping, and the formed shape usually meets the requirements of our regulations. Forming can be divided into two types: manual forming and machine forming. Manual forming is usually used as a supplementary processing or trimming field, and is rarely used. However, when processing some materials with complex shapes or prone to deformation, manual forming is still inseparable.
Sheet metal processing has developed to the point where it is mainly used to manufacture some packaging equipment shells, such as Chassiscabinet, car body, stainless steel Chassis, computer Chassis and other products, because Sheet metal processing includes stamping, bending, shearing, and cutting processes, so large Most Sheet metal processing deals with sheet metal, and a small amount of Sheet metal processing is used to manufacture some small components, such as screwdrivers, screws, small motor boxes, etc.
1. Sheet metal parts can usually be divided into three categories:
1. Flat type: refers to the usual flat punching and shearing parts.
2. Bending type: CAD is used to open according to the planned graphics before bending and welding.
3. Forming: regular surface or free surface parts processed by stretching and other forming methods. These parts are all processed from flat blanks by stamping methods such as punching and deformation, and they are very different from parts processed by usual machining methods. In the stamping processing method, bending deformation is the main processing method for causing complex spatial positional relationships of sheet metal parts.
2. Application scope of Sheet metal processing:
Sheet metal parts are widely used in electromechanical, light industry, automobile and other fields. Details include the following aspects:
1. Car field
With the improvement of domestic people's living standards, cars will enter thousands of households, which will promote the rapid development of the domestic car industry. While expanding the production scale, car manufacturers must outsource non-base businesses, so some car parts will be It is outsourced to Hefei Sheet metal processing field, which provides distribution and processing for the car field.
2. Electronic communication field
The field of communication electronics is a field that has developed rapidly in recent years, and it was also a field that used Sheet metal processing more at that time. Because of the characteristics of rapid technological updates, product diversification, and timely production in this field, this field is facing a relatively large market risk impact , the vast majority of well-known companies at home and abroad have outsourced their sheet metal business and used their limited capital for technology development; such companies include: Lucent, Bell, ABB, Nokia, Siemens, Alstom, Philips and Huawei, etc. The sheet metal processing business volume outsourced by them is tens of billions of yuan every year.
3. Elevator field
Most parts in the elevator field are sheet metal parts, and there are many types of elevator parts. Every large elevator manufacturer has dozens of suppliers for distribution and processing, such as: Xizi OTIS, Schindler, Mitsubishi Well-known elevator companies such as , Hyundai and Hitachi all have their own stable suppliers, and their outsourcing Guangzhou sheet metal business is about several billion yuan.
4. The field of precision instruments
The demand for Sheet metal processing in the field of precision instrument manufacturing is very severe. It is almost a standard to measure the technology, production and management level of Sheet metal processing companies. Some precision parts are imported from abroad and cannot be produced by Sheet metal processing companies. For example, an electronic company is a manufacturer of electronic equipment. Its outsourced sheet metal parts have not found a satisfactory supplier in Anhui. Some of its sheet metal parts are processed in Shenzhen, and some are imported from abroad; like this Sheet metal processing If the business can be processed, the profit is of course very considerable.
