Abstract

The invention relates to a steel pipe bending device, which comprises a working platform rotationally supported on a platform upright post. The steel pipe bending device is characterized in that the platform upright post is sleeved with a pipe bending wheel of which the circumferential surface is provided with a groove; the pipe bending wheel is fixedly connected with the working platform; one side of the pipe bending wheel is provided with a clamping die holder with a clamping groove; the clamping die holder is driven to clamp a workpiece in cooperation with the pipe bending wheel through a lead screw; the lead screw is in threaded fit with a nut fixed on the working platform; a guide rod is arranged in the groove close to the pipe bending wheel; the guide rod is fixedly connected with a guide rod upright post; the guide rod upright post and the platform upright post are fixed in parallel on an anchoring part. The steel pipe bending device has the advantages of simple structure, low manufacturing cost, effective prevention of harmful deformation of steel pipes, high efficiency and easiness in controlling the molding angle.

Description

technical field [0001] The present invention relates to the bending of pipes, in particular to a pipe bending device. Background technique [0002] The existing bent pipe generally adopts the method of heating and bending, that is, the steel pipe is heated to a certain temperature, and the bent pipe is formed by applying force to one end of the steel pipe. This method requires manual control of strength, which is not only inefficient, but also easily causes harmful deformation of the steel pipe during the bending process, and it is difficult to accurately control the forming angle. For this reason, the majority of technicians have invented "pipe benders", for example, "a kind of pipe bender" disclosed in the CN102950180A Chinese Invention Patent Application Specification published on March 6, 2013. This pipe bender is powered by electric power. Pipe bending machine; "a pipe bending machine" disclosed in CN103817182A Chinese Invention Patent Application Specification publish...
