Manufacturing equipment of exhaust pipe for heavy-duty vehicle

Abstract

The invention relates to the technical field of pipe processing, in particular to manufacturing equipment of exhaust pipe for heavy-duty vehicle. The manufacturing equipment comprises a frame, a sandbox, a wedge and a disc die and is characterized in that the sand box is slidably connected with the frame and provided with a sand feed inlet and a sand discharge outlet, and a tension spring is fixedly connected between the sand box and the frame; a piston is slidably connected in the sand box, a fixed rod is fixedly connected between the piston and the frame, and the piston is provided with a sand outlet with a one-way valve; the frame is provided with a sand collecting tank, the sand collecting tank is communicated with the sand box through a soft tube with a one-way valve, and the sand feed inlet and the sand discharge outlet are respectively located on two sides of the piston; the wedge is slidably connected with the frame, a pressure spring is fixedly connected between the wedge andthe frame, and an openable door for opening or closing the sand discharge outlet is slidably connected to the wedge; the disc die is rotatably connected with the frame, a torsional spring is connected between the disc die and the frame, and a fixed groove which can push the wedge to slide is fixedly connected to the circumference of the disc die. By the manufacturing equipment, the bending processing quality of the exhaust pipe can be increased effectively.

Description

technical field [0001] The invention relates to the technical field of pipe processing, in particular to a manufacturing equipment for exhaust pipes for heavy-duty vehicles. Background technique [0002] Heavy-duty vehicles refer to M-type and N-type vehicles with a maximum total mass greater than 3500Kg, and are generally used to carry large cargoes whose size and weight exceed the limits stipulated by road traffic regulations. For cars, because the exhaust gas of the car leaves the engine under great pressure, the noise it produces may make people feel crazy. At this time, the main role of noise reduction is the exhaust pipe of the car, and a muffler is installed inside it. Greatly reduces the noise of the car. The main working principle is to divert the airflow through multiple channels, and the friction and impact between these diversions will gradually reduce the flow velocity of the airflow. This repeated cycle will eventually make the exhaust gas flow out through the...

AI Technical Summary

Problems solved by technology

Since the material of the exhaust pipe is mostly stainless steel, which has a certain degree of ductility, and the structure of the exhaust pipe is hollow, the quality problem of the flattening of the exhaust pipe often occurs when the pipe is bent, which reduces the product quality of the exhaust pipe.
