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 a pipe bending process thereof. The steel pipe bending device comprises a machine body, an ejection block mechanism, a driving mechanism and a linkage mechanism; the machine body is provided with two pipe bending mechanisms, the two pipe bending mechanisms are used for fixing the two ends of a steel pipe to bend the steel pipe, and fixing rings are arranged in the two pipe bending mechanisms; the ejection block mechanism is installed on the machine body and used for cooperating with the pipe bending mechanism to bend the middle of the steel pipe to a certain radian; the driving mechanism is installed on the machine body and used for driving the pipe bending mechanism to operate; and the linkage mechanism is installed on the machine body and used for driving the fixing rings to rotate by a certain angle when the pipe bending mechanism operates. According to the steel pipe bending device, the problems that when an existing steel pipe bending device is used, due to the fact that the fixing rings and a bending disc are stressed and abraded for a long time, abrasion is uneven, and frequent replacement and maintenance are needed are solved, the later use cost is saved, operation is easy and fast, and use by people is convenient.

Description

technical field [0001] The invention relates to the technical field of a steel pipe bending device and a pipe bending process thereof, in particular to a steel pipe bending device and a pipe bending process thereof. Background technique [0002] Pipe 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 oil, gas, liquid pipeline construction and engineering bridge construction. The steel pipe itself is strong, bending the steel pipe requires a lot of force, and 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 perspective of the existing bending equipment in this field, the pipe bending device can be roughly divided into It is an electric pipe bender, a hydraulic pipe bender and a manual pipe bender, respectively relying on electric devices and hydraulic or oil pressure devices as auxiliary pow...
