Embodiment 1

[0033] A method for manufacturing a lightweight rubber shock absorber for automobiles, wherein the rubber shock absorber is composed of a rubber main spring, a plastic bracket and a metal insert, and the manufacturing method includes the following steps:

[0034] (1) Vulcanization: Put the rubber main spring 2 into a vulcanization mold for vulcanization treatment, apply a vulcanization pressure of 10 MPa to the vulcanization mold, control the vulcanization treatment temperature to 140°C, and set the vulcanization treatment time to 20 minutes.

[0035] In this step, the material of the main rubber spring is selected from natural rubber, butadiene rubber, styrene-butadiene rubber or a mixture of several in any proportion.

[0036]In this step, the mixed rubber material used in the rubber main spring 2 is prepared by using the traditional mixing process, and the components of the mixed rubber are weighed: 100g natural rubber SVR3L, 5g zinc oxide ZnO, 1.5g stearic acid, 1g micro C...

Embodiment 2

[0046] Embodiment 2: Other parts are the same as Embodiment 1, the difference is that a vulcanization pressure of 20 MPa is applied to the vulcanization mold during vulcanization in step (1).

Embodiment 3

[0047] Embodiment 3: Other parts are the same as Embodiment 1, the difference is that a vulcanization pressure of 30 MPa is applied to the vulcanization mold during vulcanization in step (1).

Abstract

The invention discloses a making method of a lightweight rubber shock absorption member for an automobile. The rubber shock absorption member is characterized in that the rubber shock absorption member is composed of a rubber mainspring, a plastic support and a metal insert, and the making method comprises the steps of vulcanization, gluing, drying, assembling, injection molding, cooling and moisture absorption. The method has the advantages of simple technology and low cost, and the lightweight rubber shock absorption member made through the method has a good performance and a long service life.

Description

technical field [0001] The invention relates to the field of automobile parts manufacturing, in particular to a method for manufacturing a lightweight rubber shock absorber for automobiles. Background technique [0002] The current energy shortage and environmental pressure are increasing, and the sustainable development of the automobile industry is facing challenges. As an effective means of energy saving, automobile lightweight technology has become one of the important research topics in the development of the automobile industry. At present, there are three main ways to realize the lightweight of automobiles: one is to optimize the structure of automobile chassis, engine and other parts, and the structural design mainly adopts methods such as front-wheel drive, high rigidity structure and ultra-light suspension structure; the other is to use In terms of materials, the weight of automobiles can be reduced through material substitution. In terms of alternative materials, ...
