Stamping die of shock-absorbing liner bushing inner sleeve and machining method of stamping die

Abstract

The invention relates to the technical field of shock-absorbing liner bushing inner sleeve machining, and discloses a stamping die of a shock-absorbing liner bushing inner sleeve and a machining method of the stamping die. The stamping die of the shock-absorbing liner bushing inner sleeve comprises an upper plate, a baseplate and a positioning core; the outer edge of the upper plate is movably connected with the outer edge of the baseplate through at least two guide rollers; an upper die is connected with the bottom side of the upper plate; a first through hole is formed in the center of the upper die; an upper die convex cutting edge is formed in the circumference of the bottom end of the first through hole; a lower die is mounted on the baseplate; a protective block is mounted on the lower die; a second through hole is formed in the center of the lower die; a lower die cutting edge is formed in the circumference of the top end of the second through hole; a third through hole is formed in the center of the protective block. The stamping die is simple in structure; cutting edges matched with saw teeth of the shock-absorbing liner bushing inner sleeve are formed in the upper die and the lower die; the die cutting edges are long in service life; fracture, corner collapse, folding and uneven surface cannot occur during the machining process.

Description

technical field [0001] The invention relates to the technical field of processing an inner sleeve of a shock-absorbing bush, in particular to a stamping die for an inner sleeve of a shock-absorbing bush and a processing method thereof. Background technique [0002] With the continuous development of science and technology, people put forward higher and higher requirements for the ride comfort and operation stability of the car. The vehicle suspension system directly affects the dynamic performance of the system, and the spring is almost the core of the dynamic performance of all suspension systems. Because the rubber material itself has the advantages of light weight, impact resistance and high-frequency vibration absorption, coupled with the improvement of rubber and metal bonding technology, metal rubber springs formed by combining metal and rubber, that is, rubber bushings, are widely used in automobile suspension. in the support device in the rack. The shock-absorbing ...

Problems solved by technology

[0003] The traditional processing technology of the inner sleeve of the shock-absorbing bushing is to process both ends of the inner sleeve of the shock-absorbing bushing on the instrument lathe, which is slow in benefit and fast in tool wear, and high in cost. 2,000 pieces are produced in a single shift, and the tool can only be used 1,000 times.

It is necessary to change the tool frequently, resulting in low production efficiency and high labor intensity
