Problems solved by technology

[0003] In order to solve the above-mentioned deficiencies in the prior art, the present invention provides a processing method of the rubber shock absorbing sleeve, which solves the problem that the torsional durability of the product decreases due to the tensile force of the rubber itself due to the shrinkage of the rubber after the rubber is vulcanized and cooled.

Embodiment Construction

[0019] The invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] Such as figure 1 , a method for processing a rubber shock absorber, comprising the steps of:

[0021] S1 vulcanizes the object into a semi-finished shock absorber;

[0022] S2 extrudes the outer circle of the shock absorber;

[0023] S3 performs cylindrical grinding on the shock absorber;

[0024] S4 produces finished shock absorbers.

[0025] The object includes an inner cover 3, an outer cover 1, a vulcanization mold and a semi-finished rubber 2, and the semi-finished rubber 2 is located between the inner cover 3 and the outer cover 1; in step S1, the inner cover 3, the outer cover 1 and the rubber 2 are bonded by heat vulcanization A semi-finished rubber shock-absorbing sleeve is formed; the rubber layer 2 of the semi-finished shock-absorbing sleeve is located between the inner sleeve 3 and the outer sleeve 1 .

[0026] In the step S2, a...

Abstract

The invention relates to the processing field of rubber shock-absorbing sleeves, and discloses a processing method of a rubber shock-absorbing sleeve, comprising the steps of vulcanizing and molding an article to form a half-finished shock-absorbing sleeve, extruding the excircle of the shock-absorbing sleeve, and grinding and processing the excircle of the shock-absorbing sleeve to obtain the finished product shock-absorbing sleeve. The invention has the advantages that the invention removes the drawing forces of the rubber layer between an internal sleeve and an external sleeve through adding an excircle extruding procedure so that the rubber is in a free state, improves the torsion-resistant performance of the product, and improves the service life of the product.

Description

【Technical field】 [0001] The invention relates to the field of processing rubber shock absorbing sleeves, in particular to a processing method for rubber shock absorbing sleeves. 【Background technique】 [0002] At present, the processing method of rubber shock absorber generally adopts the steps of vulcanization molding, cylindrical grinding processing and production of finished products, but the defect of the existing processing method is that it cannot eliminate the damage to the rubber itself due to the shrinkage of the rubber after the product is thermally vulcanized and cooled. Tensile force, in the case of not eliminating the tensile force on the rubber, the rubber is subjected to a certain frequency of circumferential torsional force during the use of the product. The combined force of the two forces intensifies the fatigue and aging of the rubber and reduces the torsional performance of the product. At present, the torsional performance of rubber shock absorbers for ...
