Embodiment 1

[0042] Embodiment 1: When working, firstly, the controller controls the action of the double-axis cylinder 14, and the two piston rods of the double-headed cylinder 14 respectively drive the two lower mold bases 12 to move through the connecting rod 15, so that the two lower mold bases 12 move toward each other. The close side moves, so that the mold cavities 121 on the two lower mold bases 12 are closed, and the metal blank obtained by the powder metallurgy process is put into the mold cavity 121, and the two fourth telescopic rods 16 pass through the connecting frame 17 drives the movement of the limiting plate 18 to limit the metal blank. The first telescopic rod 2 drives the positioning plate 19 to move to limit the movement distance of the upper mold base 20. The sixth telescopic rod 23 drives the lower mold base 12 and the mold core 21 to move downward for the first stamping, the upper die base 20 moves to the positioning plate 19 and is blocked, and the metal blank is st...

Abstract

The invention belongs to the field of stamping dies, and particularly relates to a powder metallurgy guider forming die. The powder metallurgy guider forming die aims at the solving problems that thelocal stress is excessively large when an existing guider is subjected to primary stamping, so that the situation that parts are damaged is caused, and in the case of punching at multiple stations, the parts need to be repeatedly transferred among the stations, so that the machining efficiency is low. According to the scheme, the powder metallurgy guider forming die comprises a base and fixing frames fixed on the two sides of the top end of the base, a mounting cavity is formed in the middle of the base, a double-head air cylinder is arranged in the mounting cavity, two piston rods of the double-head air cylinder are connected with connecting rods which are perpendicularly arranged, connecting holes are formed in the two sides of the top end of the mounting cavity, the connecting rods penetrates through the connecting holes and are connected with lower die seats which are connected to the top end of the base in a sliding mode, and die grooves are correspondingly formed in the side walls of one sides, close to each other, of the two lower die seats. The powder metallurgy guider forming die has the beneficial effects that the stamping effect is good, the situation that the parts aredamaged due to overlarge local stress during primary stamping is avoided, drilling can be conveniently carried out after stamping is successfully completed, and meanwhile demolding can be convenientlycarried out.

Description

technical field [0001] The invention relates to the technical field of stamping dies, in particular to a molding die for a powder metallurgy guider. Background technique [0002] With the improvement of people's living standards, vehicles have been used in various fields of people's lives. Vehicles such as battery cars, motorcycles, and cars have become necessary transportation equipment for families. The shock absorber and the shock absorber are equipped with guides. The existing guides are preliminarily processed by powder metallurgy technology, and then formed by punching and drilling; [0003] When the existing guide is punched and drilled, it is mostly formed by one-time punching or punching at multiple stations. During one-time punching, local stress is prone to be too large, resulting in damage to the parts. Stamping molding requires repeated fixing, disassembly and movement, and the processing efficiency is low; and it is not easy to demould after stamping is comple...
