In addition to the automotive industry, which industries are sheet metal processing used in?
2022-05-10 16:59:07

Sheet metal craftsmen are also called sheet metal processing. Specifically, for example, sheet metal is used to make iron drums, oil tanks, oil pots, ventilation pipes, elbow heads, Tianyuan places, funnel shapes, etc. the main processes of automobile sheet metal parts are cutting, bending, edge buckle, bending forming and welding, which requires certain geometric knowledge. Sheet metal parts are 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.

Selection of materials: the materials commonly used in sheet metal processing include cold-rolled plate, hot-rolled plate, galvanized plate, copper brass, red copper, aluminum plate, aluminum profile and stainless steel. According to different functions of products and different materials, it is generally necessary to consider the use and cost of products. For example, cold rolled sheet SPCC is mainly used for electroplating and paint baking parts, with low cost and easy forming; Aluminum plate, generally with surface oxidation, high cost and silver plating; Stainless steel is mainly used without any surface treatment and has high cost.

Drawing review, to write the process flow of parts, we must first know the various technical requirements of part drawings, and drawing review is an important link in the preparation of part process flow. Check whether the drawings are complete, the relationship between drawings and views, whether the labels are clear and complete, and mark the size unit; Assembly relationship, assembly requirements, key dimensions, etc.

Precautions for expansion: the expansion drawing is a plan view (2D) expanded according to the part drawing (3D); The deployment method should be consistent, convenient and save materials and processability.


Automobile sheet metal parts


Sheet metal refers to sheet metal with uniform thickness. Sheet metal processing refers to the process of processing a certain size of metal plate into finished products according to the set processing technology through special sheet metal processing equipment according to the product shape and structure. Sheet metal processing products are widely used in communication, electric power, industrial control, industrial equipment, medical devices, radio and television, finance, intelligent transportation, computer network, data storage, automobile and motorcycle parts and other mechanical parts manufacturing industries.

The processing technology of sheet metal products is arranged according to the product shape, product quality requirements and product functionality. The performance and type of processing equipment will be considered in the production process of auto parts. It is the main blueprint basis for product processing.

Cold rolled ordinary steel sheet is the abbreviation of ordinary carbon structural steel cold rolled plate, which is called lining plate for short. It is a steel plate with a thickness of less than 4mm made of hot-rolled steel plate of ordinary carbon structural steel after further cold rolling. Because it is rolled at room temperature, it does not produce oxide scale. Therefore, it has good surface quality and high dimensional accuracy. Combined with annealing treatment, it has good mechanical and technological properties. It is a common metal material for sheet metal processing.
