Casting is a casting cavity that poured melting metal into the metal mold. It is common in car parts after the production and processing of the product. In the process of automobile manufacturing, the rough parts made of cast iron are selected, accounting for about 10%of the vehicle weight, such as cylinders, gearboxes, steeringrs shells, rear axle shells, brake drums, various brackets. Sand molds are generally used for use in sand molds. Automobile parts processing and manufacturing cast iron. The raw materials of sand are mainly sand, and are mixed with adhesives and water. The sand material needs to be strong enough to shape the required shape and resist the erosion of the thermal iron without collapse. In order to create a type of cavity in line with the shape of the casting in the sand mold, the physical model of the wood is first made, which is called a wooden mold. The volume will shrink after the iron water is cooled. Therefore, the shape size of the wooden model needs to be increased based on the shrinkage rate on the basis of the original shape of the casting, and the surface of the turning on the surface is also thickened.
Automobile accessories processing nut forging car parts processing technology.
Forging is widely used in automotive parts processing and manufacturing. Forging is divided into free forging and physical mold forging. Freedom forging is the process of putting metal blank on the iron anvil (referred to as "forging"). The rough of the car gear and shaft is free to forge. Automotive component processing solid model forging is a processing method for forming metal blank into the forging model, and under the action of impact or pressure. The physical model forging is a bit like pressing the dough into a biscuit shape in the mold. Compared with freedom forging, steel produced steel has more complex shapes and more accurate sizes. Typical examples of car parts processing mold forging are: engine connecting rods and crankshafts, car front bridges, steering knots, etc. Precision parts processing
Processing technology of cold stamping car parts.
The processing of cold stamping machining of the car parts of the precision part machine processing manufacturers is: engine oil bottom shell, brake system bottom plate, frame and most body parts. These parts are generally formed by breeding, punching, depth, bending, edging, trimming and other processes. In order to create cold stamping parts, the mold is required. The pressure machine is generally divided into two pieces. One is installed above the pressure machine to slide up and down, and the other is installed under the pressure machine and fixed. During the processing of car parts, the blanks are placed between two stamping molds. When the upper and lower molds are combined, the stamping process is completed. The productivity of stamping processing is very high and can create parts with complex shapes and high accuracy.
