The invention discloses an automobile clutch cylinder manufacturing method and device by the aid of casting and forging techniques. The method comprises a primary casting step and a secondary forging step. In the primary casting step, a preliminary forming body is manufactured, and molten liquid is poured into a casting die composed of an upper portion casting die body and a lower portion casting die body for manufacturing. In the secondary forging step, a forged forming body is manufactured, the preliminary forming body manufactured through casting is located in a forging die assembly composed of a second upper portion die body and a second lower portion die body, the preliminary forming body is manufactured through a press machine by means of pressurization. The forged forming body comprises a lower portion main body part provided with an asymmetrical curve-shaped outer profile, a cylinder forming part, a fluid in-out hole forming part formed on the outer side of the lower portion main body part and provided with a flat part, and at least three fixing parts protruding towards the outer side of the lower portion main body part, wherein the cylinder forming part is in an upward vertical hollow cylindrical shape in the center of the lower portion main body part.
Description
technical field [0001] The invention relates to a manufacturing method and device for a cylinder for an automobile clutch by means of a casting and forging process. Background technique [0002] In an automobile, many parts of various sizes and shapes are combined in the engine, transmission, steering device, and air-conditioning device. This kind of automobile parts is mainly composed of It is made of aluminum and, in contrast to the casting process, is mainly manufactured by means of the forging process. [0003] If aluminum parts for vehicles are manufactured by cutting, etc., the processing time will take a long time, not only the productivity will be greatly reduced, but also the recycling rate of raw materials will be very low, so the production cost will be high. Therefore, when manufacturing aluminum parts for vehicles, it is manufactured by means of a casting process, which is more cost-effective than the forging process, to make the structure denser and to manufac...
