Description

Technical Field

[0001] The utility model relates to the technical field of straightening machines, in particular to a full-automatic special-shaped steel pipe straightening machine. Background Art

[0002] During the storage process after processing, the outer wall of the steel pipe will be slightly bent due to extrusion, resulting in a special-shaped steel pipe that cannot be effectively used. Before use, it will be straightened by a straightening machine. The existing technology uses extrusion to straighten the bent parts, and the concave steel pipe cannot be effectively straightened.

[0003] A Chinese patent discloses a fully automatic straightening machine for special-shaped steel pipes (authorization announcement number CN203991776U). The patented technology includes a frame, a clamping mechanism, a rotating mechanism and a straightening mechanism. The clamping mechanism is used to clamp one end of the steel pipe, and the rotating mechanism can drive the steel pipe to rotate while clamping the other end of the steel pipe. The straightening mechanism is installed between the clamping mechanism and the rotating mechanism to straighten the bent part of the steel pipe. The clamping mechanism, the rotating mechanism and the straightening mechanism are all installed on the frame. The utility model is a fully automatic straightening device that can straighten multiple bending points on the steel pipe. The whole process is automated. The traditional method of dealing with multiple bending points on the steel pipe is to break them one by one, which is cumbersome to operate. The utility model solves this problem and improves the efficiency of straightening.

[0004] This patented technology has the function of effectively straightening multiple bending points when used, but it can only straighten bent steel pipes. During the storage and transportation of steel pipes, some sections will be concave due to squeezing, and the straightener cannot effectively straighten the concave and convex parts. Therefore, those skilled in the art provide a fully automatic special-shaped steel pipe straightening machine to solve the problems raised in the above background technology. Utility Model Content
