Problems solved by technology

However, because the fluidity of the internal rubber material is too good, the air is easy to accumulate in the trough during molding, resulting in a high scrap rate of the product, so it is necessary to improve the process

Abstract

The invention discloses a production process of an air inlet rubber tube of an automobile turbocharger. The production process comprises the following steps: raw material preparation; mixing; rolling; fabric cutting; coiling; sleeving; sizing; and vulcanization. A prevulcanization step is additionally arranged between rolling and fabric cutting, wherein the prevulcanization temperature is 190+ / -5 DEG C, and the time is 8-10min. The production process disclosed by the invention improves the percent of pass of production while improving the product performance, thereby reducing the production cost of a product.

Description

technical field [0001] The invention relates to a production method of automobile parts, in particular to a production process of an automobile turbocharger air intake hose. Background technique [0002] A turbocharger is a device that uses the exhaust energy of the engine to drive the turbine and drive the compressor to increase the intake pressure of the engine. It compresses more air into the cylinder to increase the amount of fuel, thereby improving the combustion performance. In order to improve fuel economy and reduce exhaust emissions. [0003] The biggest advantage of the turbocharger is that it can greatly increase the power and torque of the engine without increasing the engine displacement. Generally speaking, the maximum output power and torque of the engine after the turbocharger is installed will increase. More than 40%, so many automobile manufacturing companies use this supercharging technology to improve the output power of the engine, so as to realize the ...
