Basic principles of sheet metal product design

Sheet metal parts refer to sheet metal parts, which can be processed by stamping, bending, stretching and other means. A general definition is the parts with constant thickness in the processing process. For any sheet metal part, it has a certain processing process, which is the so-called process flow. The following describes the basic process flow of sheet metal design and processing:

Sheet metal processing is also called sheet metal processing. Specifically, for example, the use of sheet metal to make chimneys, iron barrels, oil tanks, oil pots, ventilation pipes, large and small ends of elbows, round places, funnel shapes, etc. the main processes of chassis sheet metal process include cutting, bending, edge buckle, bending forming, welding, riveting, etc. However, the process flow of sheet metal parts and chassis sheet metal with different structures may also be different. The following is a basic process flow of sheet metal processing industry. Sheet metal processing process: sheet metal design → technical drawing → drawing unfolded drawing (NC programming) → blanking (Digital punching) → bending → riveting → welding → surface treatment (spraying or electroplating) → silk screen printing → assembly → packaging and shipment.

The processing steps of parts processed in the sheet metal workshop are: preliminary product test, product processing trial production and batch production. In the process of product processing and trial production, it is necessary to communicate with customers in a timely manner, and then carry out mass production of products after obtaining the evaluation of corresponding processing. Sheet metal processing is the key technology that sheet metal technicians need to grasp, and sheet metal processing is also an important process of sheet metal product forming. Sheet metal processing includes traditional cutting and blanking, blanking, bending forming and other methods and process parameters, as well as various cold stamping die structures and process parameters, various equipment working principles and operation methods, as well as new stamping technology and new process. These are the requirements for sheet metal designers to be familiar with the support and grip, and be able to flexibly apply them to practical work to do a good job in the design and processing of sheet metal parts.
