Turbo-charging exhaust pipe and manufacturing method of turbo-charging exhaust pipe

Abstract

The invention discloses a turbo-charging exhaust pipe and a manufacturing method of the turbo-charging exhaust pipe. The exhaust pipe comprises a rubber pipe body; the rubber pipe body comprises a rubber layer made of AEM ethylene acrylate rubber and containing a vulcanizing agent; the rubber pipe body is provided with an initial straight line section, an arc transition section, an intermediate connection section, a reducer transition section and a bottom aperture section, which are sequentially communicated with one another; and a tilt angle of 120-130 degrees is formed between the central axes of the initial straight line section and the intermediate connection section. The manufacturing method comprises the following steps of: weighing the rubber components according to a prescription,mixing the rubber components, quickly detecting the rubber components, extruding a rubber pipe, cutting and vulcanizing the rubber pipe, rinsing, detecting the rubber pipe, and transferring and printing a mark. The turbo-charging exhaust pipe provided by the invention is good in high-temperature diesel resistance, high in compression stress response, low in volume change rate after resisting high-temperature diesel, small in permanent deformation of compression, and advanced in manufacturing technique, so that the vehicle assembling requirements are met.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an exhaust pipe for an automobile engine, in particular to a turbocharged exhaust pipe and a manufacturing method thereof. Background technique [0002] With the continuous exploitation, application and scarcity of global oil resources, as well as the long-term threat caused by the global oil supply chain, international oil prices are constantly fluctuating and rising, and the contradiction between supply and demand is becoming increasingly tense. In order to reduce the fuel consumption of automobiles, protect the atmosphere from being destroyed, benefit mankind, and maintain ecological balance, major automobile factories at home and abroad have been researching and developing engines with turbocharging systems. Turbocharging system includes turbocharger, intercooler, intake bypass valve, exhaust bypass valve and supporting intake and exhaust pipes. A turbocharger is an air pump that u...

Problems solved by technology

Since the working environment temperature of the engine can reach more than 200 degrees, the rubber hose material is required to have high temperature resistance, diesel resistance, and no cracks, no swelling, no leakage, etc. when used in a long-term high-temperature hot oil state, while ordinary rubber hoses Materials cannot meet such harsh conditions and special rubber materials are required

If an ordinary rubber hose is used, it will not only easily cause air leakage and deformation of the hose, which will make the system unable to operate normally, but also may cause a fire due to high temperature fuel injection, causing greater harm
