Background
The straightening machine is equipment for straightening metal sections, bars, pipes, wires and the like. The straightener extrudes the bar material and the like through the straightening roller to change the straightness. Generally, two rows of straightening rollers are provided, and the number of the straightening rollers is different. There are also two-roll straightening machines, which straighten materials of different diameters by means of the angular change of two rolls (concave in the middle, hyperbolic roll). The main types are a pressure straightener, a balance roll straightener, a shoe roll straightener, a rotary reverse bend straightener and the like.
The working principle of the straightening machine is as follows: the rollers are positioned at an angle to the direction of movement of the article being straightened, two or three of the larger rollers being driven pressure rollers which are driven by motor belts to rotate in the same direction, and the other of the smaller rollers being driven pressure rollers which are caused to rotate by friction against the rotating round bar or tube. The small rollers can be adjusted in position simultaneously or separately in a forward or backward direction in order to achieve the desired compression of the product by the rollers, and generally the greater the number of rollers, the greater the precision of the straightened product. After the product is bitten by the roller, the product is continuously moved linearly or rotationally, so that the product is subjected to deformation such as compression, bending, flattening and the like in all aspects, and finally the aim of straightening is fulfilled.
After the main rolling process of the seamless steel pipe is finished, straightening the straightness of the axis of the steel pipe is needed, and when the steel pipe enters a straightening roller for straightening, the tail end of the steel pipe which does not enter the straightening roller can generate radial swing due to the effect of certain bending and the straightening force of the steel pipe; at the moment, an inlet guide sleeve is required to be added at the inlet end of the straightening machine; the guide sleeve has the guiding function and overcomes the radial swing of the steel pipe. In the prior art, an inlet guide sleeve is a baffle similar to a double-opening door according to the size of a steel pipe, the opening of the baffle is adjusted through a speed reducer and a screw rod, and the baffle is driven to open and close through an oil cylinder. However, the adjusting and driving mechanism is found to have insufficient design strength, often structural damage occurs, and the tendency of the steel pipe to swing upwards cannot be limited in use.

The straightener extrudes the bar material and the like through the straightening roller to change the straightness. Generally, two rows of straightening rollers are provided, and the number of the straightening rollers is different. There are also two-roll straightening machines, which straighten materials of different diameters by means of the angular change of two rolls (concave in the middle, hyperbolic roll). The main types are a pressure straightener, a balance roll straightener, a shoe roll straightener, a rotary reverse bend straightener and the like. The working principle of the straightening machine is as follows: the rollers are positioned at an angle to the direction of movement of the article being straightened, two or three of the larger rollers being driven pressure rollers which are driven by motor belts to rotate in the same direction, and the other of the smaller rollers being driven pressure rollers which are caused to rotate by friction against the rotating round bar or tube. The small rollers can be adjusted in position simultaneously or separately in a forward or backward direction in order to achieve the desired compression of the product by the rollers, and generally the greater the number of rollers, the greater the precision of the straightened product. After the product is bitten by the roller, the product is continuously moved linearly or rotationally, so that the product is subjected to deformation such as compression, bending, flattening and the like in all aspects, and finally the aim of straightening is fulfilled.
After the main rolling process of the seamless steel pipe is finished, straightening the straightness of the axis of the steel pipe is needed, and when the steel pipe enters a straightening roller for straightening, the tail end of the steel pipe which does not enter the straightening roller can generate radial swing due to the effect of certain bending and the straightening force of the steel pipe; at the moment, an inlet guide sleeve is required to be added at the inlet end of the straightening machine; the guide sleeve has the guiding function and overcomes the radial swing of the steel pipe. In the prior art, an inlet guide sleeve is a baffle similar to a double-opening door according to the size of a steel pipe, the opening of the baffle is adjusted through a speed reducer and a screw rod, and the baffle is driven to open and close through an oil cylinder. However, the adjusting and driving mechanism is found to have insufficient design strength, often structural damage occurs, and the tendency of the steel pipe to swing upwards cannot be limited in use.
