Description

Technical Field

[0001] The utility model relates to the technical field of seamless steel pipe processing equipment, in particular to a straightening mechanism for seamless steel pipe production. Background Art

[0002] A steel pipe is a tubular component made of metal steel, while a seamless steel pipe is made by punching a whole round steel bar. It is named because there is no exposed weld on its surface. There are many ways to produce seamless steel pipes. According to the different production methods, the prepared seamless steel pipes are divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, extruded seamless steel pipes, jacking pipes, etc.

[0003] Seamless steel pipes are used in various fields in life. They can be used as petroleum geological drilling pipes, cracking pipes for petrochemical industry, boiler pipes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors, and aviation. They have high structural strength and strong durability.

[0004] Seamless steel pipes cannot be put into use directly after they are produced. They need to be straightened to make the originally slightly curved seamless steel pipes straight so that they can be truly put into use. However, the current devices for straightening seamless steel pipes have a simple structure, and the straightening effect on seamless steel pipes is not ideal. They are also prone to deformation and collapse of some structures of seamless steel pipes. The operation process is relatively complicated, and the processing efficiency is low, which affects the production progress. Utility Model Content

[0026] In this embodiment: the second motor 902 is started to drive the second threaded rod 901 to rotate, thereby driving the moving plate 903 to move in the left and right directions.

[0027] See also Figure 2 A cylinder 11 is fixedly installed at the bottom of the movable plate 903, and the movable end of the cylinder 11 is fixedly installed on the hanging plate 4.

[0028] In this embodiment, when the movable plate 903 moves, the hanging plate 4 is driven to move left and right by the cylinder 11. At the same time, the cylinder 11 can control the height of the hanging plate 4 to facilitate the straightening work.

[0029] See also Figure 3 A fixing rod 12 is fixedly installed on the lower side of the right end of the left support plate 2, a positioning plate 13 is fixedly installed on the right end of the fixing rod 12, and the left end of the positioning rod 7 is fixedly installed on the positioning plate 13.
