Abstract

The invention belongs to the field of diesel engine equipment and particularly relates to an air inlet tube for an air cleaner and a manufacturing technology for the air inlet tube. The air inlet tube comprises an air inlet elbow and a casing tube. The casing tube is arranged at an air inlet elbow and air cleaner connection end, the casing tube is integrated with the air inlet elbow, and the casing tube is a stamping tension portion of the air inlet elbow. The air inlet tube is smooth and flat in surface, smooth in arc, attractive and elegant, simple in production technology, capable of reducing the production cost and improving the work efficiency, convenient to mount and beneficial to environmental protection.

Description

technical field [0001] The invention belongs to the field of diesel engine equipment, in particular to a manufacturing process of an air filter intake pipe. Background technique [0002] In the diesel engine cooling system, the air filter plays the role of air filtration, which filters the impurities and dust in the air, and then sends clean air into the engine through the intake pipe. The intake pipe is a component connecting the engine air inlet and the air filter, and one end of the air intake pipe is fixedly connected with the air filter through a sleeve, and the intake pipe and the sleeve pipe are independent components. [0003] The following problems exist in the production of the existing air intake pipe: the air intake pipe and the casing are welded by acetylene gas, the process is complicated, the surface of the workpiece is rough, the sweat tumor is serious, and it is very easy to leak and break, and there are many processes. Complex and long production cycle. T...
