Cold extrusion processing equipment of high-precision automobile clutch

Abstract

The invention discloses cold extrusion processing equipment of a high-precision automobile clutch. The cold extrusion processing equipment comprises a controller, a base and a top seat, wherein a control system is arranged in the controller, the base is used for fixing the controller, the top seat is arranged above the base, a servo hydraulic system is used for supplying oil to a hydraulic cylinder so as to drive a movable die to move to a fixed die by the hydraulic cylinder, a containing disc which is used for containing a rivet is arranged on one side of the fixed die, an ejection mechanismwhich is used for ejecting the rivet is arranged in the containing disc, a riveting mechanism which is located on one side of the containing disc is arranged on the base, and the rivet on the containing disc can be sucked and moved to the upper part of the fixed die by the riveting mechanism. Compared with the prior art, the cold extrusion processing equipment has the advantages that the flow of hydraulic oil which flows into the hydraulic cylinder is controlled by using the servo hydraulic system, so that the displacement, the moving speed and the pressure of the movable die are accurately controlled, the rivet is prevented from being excessively pressed, additionally, the rivet is mechanically installed, the installation accuracy is increased, the installation mode that the rivet extendsinto the die manually is avoided, and the product quality is increased.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of automobile clutch processing equipment, in particular to a high-precision automobile clutch cold extrusion processing equipment. [0003] 【Background technique】 [0004] The automobile clutch is controlled by the air conditioner switch, thermostat, air conditioner amplifier, pressure switch, etc., and turns on or off the power transmission between the engine and the compressor when needed. In addition, when the compressor is overloaded, it can also play a certain protective role. Among them, the electromagnetic coil is fixed on the shell of the compressor, the suction cup of the automobile clutch is connected with the main shaft of the compressor, and the pulley is installed on the head cover of the compressor through a bearing, and can rotate freely. When the air conditioner switch is turned on, the current passes through the electromagnetic coil of the electromagnetic clutch, and the electromag...

AI Technical Summary

Problems solved by technology

[0005] Among them, the automobile clutch suction cup assembly mainly includes a suction cup, a wheel hub, and a fixed plate. The fixed plate with the wheel hub and the suction cup are installed on the periphery of the fixed plate. The two are fixed together by rivets, and riveting processing requires cold extrusion processing equipment for pressing. During the press-fitting process, since the stroke and pressure of the hydraulic cylinder in the prior art are generally set at the factory, and the temperature of the hydraulic oil has a great influence on the hydraulic pressure, excessive press-fitting often occurs, resulting in scrapping The rate is high; and before the rivet is pressed, it needs to be manually penetrated into the riveting hole of the fixing plate and the suction cup, the number of which is large, and the deviation of the installation angle will directly affect the follow-up pressing effect, which is extremely difficult to use. inconvenient
