Sheet metal mechanic is also called sheet metal fabrication. Specifically, for example, the use of sheet metal to make iron barrels, fuel tanks, ventilation pipes, elbows and sizes, Tianyuan places, funnel-shaped, etc. The main process of automobile sheet metal parts is cutting, bending and buckle. Edges, bending and welding require a certain knowledge of geometry. Sheet metal parts are thin-plate hardware parts, that is, parts that can be processed by means of stamping, bending, stretching, etc. A general definition is a part with a constant thickness during fabrication.
The selection of materials, the materials generally used in sheet metal fabrication are cold-rolled sheet, hot-rolled sheet, galvanized sheet, copper brass, red copper, aluminum plate, aluminum profile, stainless steel. According to the different functions of the product, the materials used are different, and the use and cost of the product generally need to be considered. Such as: cold-rolled sheet SPCC, mainly used for electroplating and baking paint, low cost and easy to form; aluminum plate, generally used for surface oxidation, high cost, with silver plating; stainless steel, mainly used without any surface treatment, high cost.
Drawing review, to write the process flow of the part, you must first know the various technical requirements of the part drawing, then the drawing review is an important link in the compilation of the part process flow. Check whether the drawings are complete, the relationship between drawings and views, whether the markings are clear and complete, and whether the dimension units are marked; assembly relationships, key dimensions of assembly requirements, etc.
Precautions for unfolding, the unfolding drawing is a plan view (2D) based on the part drawing (3D); the unfolding method should be suitable to save materials and processability.
Sheet metal refers to a thin sheet of metal with uniform thickness. Sheet metal fabrication refers to the process of fabrication a certain size of metal plate into a finished product according to the set fabrication technology through special sheet metal fabrication equipment according to the product shape and structure. Sheet metal fabrication products are widely used in communications, electric power, industrial control, industrial equipment, medical equipment, radio and television, finance, intelligent transportation, computer networks, data storage, automobile and motorcycle parts and other mechanical parts manufacturing industries.
Sheet metal product fabrication technology is scheduled according to product shape, product quality requirements, and product functionality. In the production process of auto parts, the performance of the fabrication equipment and the type of equipment will be considered. It is the main blueprint basis for product fabrication.
Cold-rolled ordinary thin steel plate is the abbreviation of ordinary carbon structural steel cold-rolled plate, referred to as lining plate. It is made of ordinary carbon structural steel hot-rolled steel plate and further cold-rolled into a steel plate with a thickness of less than 4MM. Because it is rolled at room temperature, no oxide scale is produced. Therefore, the surface quality is good, and the dimensional accuracy is high. In addition, annealing treatment, Its mechanical properties and process properties are good, and it is a metal material commonly used in sheet metal fabrication.
