Description

technical field [0001] The invention belongs to the technical field of auto parts manufacturing, in particular to a clutch cold extrusion die, in particular to a clutch cold extrusion die and a use method. Background technique [0002] With the continuous development of science and technology and industrial technology, people's living standards have been greatly improved. As a means of transportation, automobiles are used more and more widely. Clutches are a common shafting component of automobiles. The function is to combine or separate the two shafts at any time when the machine is working according to the needs, so as to ensure the smooth start of the car or prevent the overload of the transmission system. The clutch is located in the flywheel housing between the engine and the gearbox, and the clutch assembly is fixed on the flywheel with screws. On the rear plane, the output shaft of the clutch is the input shaft of the gearbox. When the car is running, the driver can s...

Problems solved by technology

The tooth shape needs to be milled one by one, the production efficiency is low, the cost is high, and the overall performance of the part cannot be optimized at the same time. In addition, the traditional processing method has many processes, and each process needs to be re-clamped and installed and positioned. Errors occur. With the progress of society, low energy consumption, low cost, high efficiency and improving the internal and appearance quality of products have become the development trend of advanced manufacturing technology in the 21st century. Therefore, a new production method is proposed for the clutch to overcome the traditional cutting process. Therefore, it is necessary to design a machine with reasonable design, simple structure, convenient installation and operation, flexibility and reliability, low processing cost, stable operation, good manufacturability, time saving and labor intensity reduction. , high production efficiency, good parts forming quality, high economic benefits, safety and reliability, and long service life clutch forging dies are very necessary. It is of great significance to improve the production efficiency of clutches, reduce production costs, and improve economic benefits. Practical value
