Abstract

The invention discloses a production process of a rubber diaphragm of an automobile brake chamber, and aims to solve the defects that in the prior art, a product has low yield and easiness in exposed and deflected arrangement, so that the service life and the service performance of the product are influenced, and the production cost is high. The production process has the main steps of die preparation, rubber material formation, framework formation, production formation, and three times of vulcanization, so as to obtain the product. Under the premise of not influencing the production efficiency of the product, the product yield and the product properties are improved and the production cost is low, so that the deflection and the exposed arrangement of the diaphragm cloth can be radically solved.

Description

technical field [0001] The invention relates to the technical field of production of rubber diaphragms of automobile brake air chambers, in particular to a production process of rubber diaphragms of automobile brake air chambers. Background technique [0002] Automobile brake air chamber rubber diaphragm is a key component widely used in various types of heavy-duty vehicles (trucks, trailers, passenger cars, military vehicles, etc.) braking systems and air brakes for sealing and transmitting pressure braking. Rubber products related to machine crashes, also known as safety components. With the increasing requirements of high speed, comfort and reliability (safety) of automobiles, higher requirements are placed on rubber diaphragms, one of the key components of automobile brake chambers. [0003] At present, the production process of the diaphragm is mainly divided into two types: [0004] 1. The most common production process is the one-time vulcanization process dominated...
