Problems solved by technology

[0003] When the existing steel pipe bending device is in use, the fixed rings on both sides and a certain point on the side and the side of the bending plate will wear more seriously, while other positions will wear lightly. Long-term use will cause partial position of the bending device Due to wear and tear, frequent replacement of parts is required, but the wear and tear on other positions is relatively small. Such frequent replacement greatly increases the cost of device use and also increases the work burden of workers.

Abstract

The invention discloses a steel pipe bending device and its bending process, comprising a machine body, a jacking mechanism, a driving mechanism and a linkage mechanism. The body is provided with two bending mechanisms, and the two bending mechanisms are used for Fix the two ends of the steel pipe to bend the steel pipe. The two bending mechanisms are equipped with a fixed ring. radian, the driving mechanism is installed on the machine body to drive the pipe bending mechanism to run, and the linkage mechanism is installed on the body to drive the fixed ring to rotate at a certain angle when the pipe bending mechanism is running. The device solves the problem that when the existing steel pipe bending device is used, the fixed ring and the bending plate are subjected to a certain surface for a long time to wear and tear, resulting in uneven wear and frequent replacement and maintenance. It saves the cost of later use, and the operation is simple and fast, which is convenient for people use.

Description

technical field [0001] The invention relates to the technical field of a steel pipe bending device and a pipe bending process, in particular to a steel pipe bending device and a pipe bending process. Background technique [0002] Bending is a processing technology for bending steel pipes. It is divided into two types: cold simmering and hot pushing. It is mainly used for pipeline construction and engineering bridge construction for oil, gas, and liquid infusion. The strength of the steel pipe itself is high, and the bending of the steel pipe requires a large amount of force. It is very difficult to bend the steel pipe by hand. Generally, a certain device is required to realize the bending of the steel pipe. From the existing bending equipment in the field, the pipe bending device can be roughly divided into two categories. For electric pipe bending machine, hydraulic pipe bending machine and manual pipe bending machine, the bending of steel pipe is realized by relying on ele...
