[0002] A straightening machine is a device used to straighten metal profiles, bars, pipes, wires, etc. The straightening machine uses straightening rollers to squeeze bars and other materials to change their straightness. Generally, there are two rows of straightening rollers with varying numbers. There are also two-roller straightening machines, which rely on the angle changes of the two rollers (concave in the middle, hyperbolic rollers) to straighten materials of different diameters. The main types include pressure straightening machines, balanced roller straightening machines, shoe roller straightening machines, rotary reverse bending straightening machines, etc.

[0003] When the existing straightening machine is straightening the seamless steel pipe, after straightening one end of the seamless steel pipe is completed, it will move out of the straightening machine. At this time, the other end of the seamless steel pipe is still inside the straightening machine and is in a semi-suspended state. Since the straightening machine will generate vibration when working, it is easy to cause the seamless steel pipe to fail the straightening, which reduces the straightening effect of the straightening machine on the seamless steel pipe. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that when the existing equipment is in use, the other end of the seamless steel pipe is still inside the straightener, and the straightener will generate vibration when working, which easily leads to unqualified straightening of the seamless steel pipe. A seamless steel pipe straightener is proposed.

At this time, the two electric push rods 106 are started. Since the output ends of the two electric push rods 106 are fixedly connected to one side of the outer wall of the movable support frame 107, and the slider 103 installed at the bottom of the movable support frame 107 is embedded in the strip groove 102, the stability of the movement of the movable support frame 107 is improved. Secondly, the moving speed of the movable support frame 107 is kept consistent with the speed of the seamless steel pipe out of the straightening machine, and the straightened seamless steel pipe will not be in a semi-suspended state. After all straightening is completed, it will be collected, which improves the qualified rate of seamless steel pipe straightening, thereby improving the straightening effect of the straightening machine on seamless steel pipes.
