Description

Technical Field

[0001] The utility model belongs to the field related to automotive clutches, and relates to a forging device for processing automotive clutches that facilitates die replacement. Background Art

[0002] An automotive clutch is a component installed between an engine and a transmission. Its main function is to control the power transmission between the engine and the transmission. During the production and processing of automotive clutches, a forging device is required. A forging device is a mechanical equipment used for metal processing. It is a forming processing method that uses the hammer head, anvil block, punch of a forging machine or applies pressure to a blank through a die to make it undergo plastic deformation, thereby obtaining a workpiece with the required shape and size.

[0003] Currently, a Chinese patent with the publication number CN218361846U discloses a forging device in the market. The forging device includes a frame, a template, a hydraulic cylinder and a cleaning mechanism arranged on the frame. A pressure column is provided at the output end of the hydraulic cylinder, and the pressure column cooperates with the template to achieve forging. The cleaning mechanism includes: a sliding rod that is horizontally slidably arranged on the frame, an inclined groove is opened on the sliding rod, and a second connecting rod is fixed at one end of the sliding rod; a collecting hopper is arranged at the other end of the sliding rod and above the template; a push rod is connected to the pressure column to achieve synchronous up and down movement; the bottom of the push rod is an inclined surface for cooperating with the inclined groove, so that when the pressure column descends, the collecting hopper moves away from above the template to avoid the working position of the pressure column; a tension spring has one end connected to the second connecting rod and the other end connected to the frame, and is used to make the collecting hopper return above the template when the pressure column ascends; a blower is connected to the collecting hopper through a first connecting pipe to suck off the oxidized skin slag. The utility model can timely clean the oxidized skin peeled off during forging, ensure the accuracy and performance of the forging, and preferably solve the above problems. However, in the actual use process, due to the heavy weight of the die required for forging itself, multiple workers are needed to jointly lift and carry the die when replacing the die. Moreover, such a replacement method is not only cumbersome and laborious, but also delays the processing time of the overall automotive clutch. In addition, the above comparative case also lacks means for facilitating the replacement of the die required for forging, which is not suitable for batch forging processing of automotive clutches and increases the labor intensity of workers. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a forging device for processing automotive clutches that facilitates die replacement, aiming to solve the problems.

[0005] To solve the above technical problems, the utility model provides a forging device for processing automotive clutches that facilitates die replacement, including a support base for placing the die and the workpiece for forging.

[0006] The front push frame is arranged in front of the support seat and is used to assist workers in pushing the mold. An I-shaped platen is fixedly installed above the support seat. A lower mold is arranged above the I-shaped platen. A fixed block is arranged on one side of the lower mold. A pressing rod is movably connected inside the fixed block. A telescopic cylinder is arranged at the bottom of the pressing rod.

[0007] The upper mold is arranged above the lower mold and is used to close with the lower mold to complete forging. A fixing bolt passes through the upper part of the upper mold.

[0014] The present utility model is further configured as an auxiliary tool for an automotive clutch plate that facilitates hole installation. Compared with the prior art, the present utility model provides a forging device for automotive clutch processing that facilitates mold replacement:

[0015] 1. There are a front push frame, an I-shaped platen, a lower die, an upper die, a docking plate, a docking groove and a docking block. According to the different types of automotive clutches that need to be forged currently, the matching lower die and upper die can be selected. The lower die and the upper die are pushed onto the I-shaped platen by the front push frame. Then, the telescopic cylinder inside the fixing block is opened, and the telescopic cylinder jacks up the pressing rod upwards. The other end of the pressing rod touches down on the lower die, so that the replaced lower die can be fixed. Then, the upper die and the docking plate are connected by fixing bolts. The forging head is controlled to descend, so that the docking block is inserted into the docking groove and then fixed by fixing screws. In this way, the replacement of the upper and lower dies is completed, avoiding the cumbersome operation of the heavy mold itself and the need for multiple workers to lift it together when replacing the mold. At the same time, this method of replacing the mold is fast and rapid, which not only facilitates the forging of a large number of automotive clutches by this automotive clutch forging device, but also reduces the labor intensity of workers;

[0016] 2. There are connecting diagonal rods, a servo motor, a fixing rod, a bottom groove plate, a driving motor, a threaded lead screw and a threaded nut sleeve.
