Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a manufacturing and forming method for the stainless steel intercooled intake pipe, which solves the problem that the traditional intercooled intake pipe often needs to have sufficient tolerance to high-temperature air when it is used, and must ensure that it is It will not break when encountering low-temperature air during the interval of continuously receiving high-temperature air, but the existing intercooler intake pipe can only withstand high-temperature air for a short period of time. When used for a long time, the intercooler intake pipe is easy to rust and crack, which affects the use safety issue

Abstract

The invention discloses a stainless steel intercooling air inlet pipe manufacturing forming method. The method specifically comprises the following steps of, first, a common mechanical equipment preparation stage; second, heating forming and testing of an intercooling air inlet pipe; third, testing operation of the intercooling air inlet pipe; fourth, high-temperature heat treatment of the intercooling air inlet pipe; and fifth, surface polishing treatment of the intercooling air inlet pipe. The invention relates to the technical field of air inlet pipes. According to the stainless steel intercooling air inlet pipe manufacturing forming method, comprehensive air leakage detection is conducted on the intercooling air inlet pipe in the blank state, air-leaking products are effectively prevented from going out of a production line, the percent of pass of later-period products is increased, and cracks of the products are prevented from being enlarged due to long-term high temperature whenthe products are in use; and because of the heat treatment on the intercooling air inlet pipe in the blank state, the operation efficiency of the intercooling air inlet pipe is effectively improved, and the stability of the intercooling air inlet pipe in the working process is further improved through repeated operation of heat treatment.

Description

technical field [0001] The invention relates to the technical field of intake pipes, in particular to a method for manufacturing a stainless steel intercooled intake pipe. Background technique [0002] A turbocharger is actually an air compressor that compresses air to increase intake air. It uses the inertial momentum of the exhaust gas discharged from the engine to drive the turbine in the turbine chamber, and the turbine drives the coaxial impeller, which presses the air sent by the air filter pipe to pressurize it into the cylinder. When the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase synchronously, and the impeller compresses more air into the cylinder. The pressure and density of the air increase to burn more fuel. Increase the amount of fuel and adjust the engine speed accordingly. The output power of the engine can be increased. The hot air compressed in the turbocharger is sent directly to the intercooler. [0003] ...
