Processing Technology Of Auto Parts

Processing technology of auto parts: 1. Casting; 2. Forging; 3. Welding; 4. Cold stamping; 5. Metal cutting; 6. Heat treatment; 7. Assembly.

Forging is a manufacturing method in which molten metal materials are poured into the mold cavity, cooled and solidified to obtain goods. In the automotive industry, many parts are made of pig iron in pig iron, accounting for about 10% of the net weight of vehicles, such as cylinder liner, gearbox housing, steering system housing, automobile rear axle housing, brake system drum, various supports, etc. sand mold is generally used in the production of cast iron parts.

Cold die or sheet metal stamping die is a production method in which sheet metal is cut or formed by force in the stamping die. Daily necessities, such as brine pot, lunch box and washbasin, are made by cold stamping. The auto parts produced and processed by cold stamping die include: automobile engine oil pan, brake system bottom plate, automobile window frame and most body parts.

Electric welding is a production method of locally heating or simultaneously heating and stamping two metal materials. Generally, the welding process of holding the mask in one hand and holding the electrode holder and welding wire connected with the cable in the other hand is called manual arc welding, but manual arc welding is rarely used in the automotive industry, and welding is the most used in body production. Welding is applicable to the welding of electric welding cold-rolled steel plate. During actual operation, two electrodes are used to pressurize the two thick steel plates to make them fit together. At the same time, the feeding point is energized, heated and melted, and then firmly and tightly connected.

Turning of metal materials is to drill the metal material blank step by step with a milling cutter; Make the product obtain the required product appearance, specification and roughness. such as oil pipe quick connector parts. Turning of metal materials includes milling and machining. Milling worker is a production mode in which workers use hand-made special tools to carry out cutting. The actual operation is sensitive and convenient. It is widely used for installation and maintenance. Processing and manufacturing rely on CNC lathe to realize drilling, including turning, planing, milling, drilling, grinding and other methods.

Heat treatment process is a way to reheat, insulate or cool solid steel to change its organizational structure to meet the application standards or technical standards of parts. The number of heating ambient temperature, the length of holding time and the speed of cooling efficiency will lead to different structural changes of steel.

Then connect various components (bolts, nuts, oil pipe clamp, pins or buckles, etc.) to form a complete vehicle according to certain regulations. Whether the components or the components of the whole vehicle need to cooperate and correlate with each other according to the requirements of the design drawings, so that the components or the whole vehicle can realize the set characteristics.
