technical field

The utility model belongs to the technical field of clutch processing.

Background technique

The driven disc in the automobile clutch is the key component in the entire clutch, which directly affects the performance of the clutch. The driven disc is a thin-walled and large-sized part. In the production process, it is produced by carbonitriding, quenching and high temperature leveling. However, the conditions of use are very harsh, and it can only be used after heat treatment. When the driven disc is subjected to a large amount of deformation of the parts under the combined effect of tissue stress and thermal stress after heat treatment, it needs to be leveled to be practical. The traditional leveling uses heating The flat plate mold of the high temperature and high pressure is used to level the parts.

When using traditional production, the leveling process has the following defects: it requires a high temperature of 350 degrees, and the processing cycle of each heating and cooling takes 12 hours, which is a waste of time. When the deformation of the parts in the previous process (carbonitriding-quenching) is large, it is difficult to level, and the flatness of the finished product becomes poor. In the case of high temperature and high pressure, the position of parts is prone to deviation.

The hydraulic cylinder block 1 of the hydraulic press is fixed on the upper fixing plate 3 through the upper connecting plate 13 , the hydraulic cylinder plug 14 of the hydraulic press is fixedly connected to the fixed connecting body 12 through the upper fixing plate 3 , and the fixed connecting body 12 is fastened to the slide rail seat 11 by bolts. On one side of the slide rail seat 11, a slide rail sleeve 10 is fixedly installed, the slide rail sleeve 10 and the slide rail 9 form a track fit, the slide rail 9 is fixed on the column 4, and the slide rail sleeve 10 and the slide rail 9 are matched with each other , play a guiding role.

An upper die holder 15 is fixedly installed under the slide rail base 11 , an upper die holder installation groove 30 is opened in the middle of the upper die holder 15 , and the upper die holder 17 is installed in the upper die holder installation groove 30 . The side wall is provided with a card slot 24, and the upper mold stable frame 15 corresponding to the card slot 24 is provided with a mold locking pin groove 31. The return spring 25, the rear end of the return spring 25 is clamped on the clamping table 33 in the clamping pin groove 31, the front end is clamped on the clamping block 32 at the end of the clamping pin 27, and the end of the extension part of the clamping pin 27 has a handle 26. The clamping mechanism is a mechanism for installing the upper die base. For convenience, a manual moving mechanism is used. Hold the handle by hand and pull it outward to drive the clamping pin to pull out and leave the clamping pin hole (slot 24). Therefore, the locking of the upper die seat is released, and the return spring at this time is in a compressed state. If released, the locking pin will be pushed into the vacant upper die seat mounting groove. After installing the new upper die holder with the upper die, pull out the clamping pin, put the upper die holder into the installation groove of the upper die holder completely, and ensure that the clamping pin hole corresponds to the clamping pin groove. Release the handle, and the clamping pin will be inserted directly into the clamping pin hole, thereby locking the upper die holder.
