Structures for Exhaust Pipe Bending

Abstract

The invention discloses a bending structure for an exhaust pipe. The bending structure for the exhaust pipe comprises a supporting frame. A stand column is installed on the supporting frame. An annular groove is formed in the stand column. A hydraulic cylinder is installed on the supporting frame. The output end of the hydraulic cylinder is connected with a stop block which is just opposite to the arc top of the annular groove. A semi-circular groove is formed in the stop block. Roller wheels are installed on the inner walls of the two ends of the semi-circular groove and the bottom of the semi-circular groove, and the roller wheels are connected with the semi-circular groove through a rotating shaft. With the arc top of the side, just opposite to the stop block, of the annular groove being the supporting point, the two ends of the semi-circular groove respectively apply action force on a straight pipe fitting so that the straight pipe fitting can start to bend and deform; the annular groove and the semi-circular groove are in cooperation so that the straight pipe fitting can gradually deform in a bent sealed space; as all parts of the straight pipe fitting in the bent sealed space are evenly stressed, the situation that the bent part of the straight pipe fitting protrudes locally is avoided, and the service life of the exhaust pipe is prolonged.

Description

technical field [0001] The invention relates to a pipe bending device, in particular to a structure for bending an exhaust pipe. Background technique [0002] The loader is mainly used for shoveling, loading, unloading, transporting bulk materials such as soil and stone, and can also perform light shoveling operations on rocks and hard soil. If you change to a different working device, it can also complete the work of bulldozing, lifting, loading and unloading other materials. In highway construction, it is mainly used for filling and excavation of roadbed engineering, aggregate and loading of asphalt and cement concrete yards. Because it has the advantages of fast operating speed, good maneuverability and light operation, it has become the main machine in earth and stone construction. [0003] When the loader is working, due to its heavy workload, compared with the angle direction of the exhaust pipe of cars and light family cars, it is generally backward and parallel to ...

AI Technical Summary

Problems solved by technology

In the production process of the exhaust pipe, simple pipe bending equipment is usually used for bending the exhaust pipe, and the pipe fittings are bent manually. Although this method is simple and easy, it not only increases the work intensity of the staff , There will be obvious wrinkles on the exhaust pipe after the bend, that is, the pipe fittings are partially bulged due to uneven force, and the local bulges of the pipe fittings are prone to metal fatigue. Corrosion, so that the tail gas emission of the loader is not up to standard, causing environmental pollution
