The purpose of heat treatment is to improve the material mechanical properties of steel pipes and precision steel pipes. However, after high-temperature heat treatment, the steel pipes will have bending deformation problems in the length direction. They must undergo a straightening preparation process to meet the straightness requirements of the finished product or subsequent processed products.

[0003] The patent with the patent announcement number CN216911617U discloses a high-efficiency heat treatment equipment for seamless steel pipe processing, including a heat treatment base, characterized in that the upper end of the support leg frame is welded and installed at the bottom of the heat treatment base, and there are two support leg frames installed in total.

A steel pipe heat treatment furnace is provided on one side of the steel pipe impurity remover, and a mounting support plate is provided on one side of the steel pipe heat treatment furnace. There are two mounting support plates in total. The setting of the steel pipe impurity remover in the patent is driven to rotate by belt transmission. The steel pipe straightener removes the metal impurities attached to the surface of the steel pipe, and can be cleaned more conveniently by rotating friction to avoid affecting subsequent operations.

[0004] However, the current preparation device has the following problems: the preparation device is not convenient for all-round straightening of the steel pipe during the straightening process, and the steel pipe is only subjected to the up and down straightening force, which will cause the straightening force on the steel pipe to be uneven and cause the quality of the steel pipe product to decline. Therefore, we propose a preparation device and a preparation process for seamless stainless steel pipes. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a preparation device and a preparation process for a seamless stainless steel pipe, which solves the problem proposed in the above background technology that the preparation device is not convenient for all-round straightening of the steel pipe during the straightening process, and the steel pipe is only subjected to the upward and downward straightening forces, which causes the straightening force on the steel pipe to be uneven, resulting in a decrease in the quality of the steel pipe product.

The telescopic end of the first electric push rod pushes the fork-shaped slide plate to drive the movable roller to move downward, and the movable roller presses against the steel pipe for straightening. At the same time, the telescopic end of the second electric push rod pulls the fork-shaped pressure rod to move downward, and the fork-shaped pressure rod pushes the hinged rod to drive the clamping plate to move toward the center of the movable roller, and the clamping plate drives the fixed plate to move synchronously, and the fixed plate presses and straightens both sides of the steel pipe, thereby ensuring that the straightening force on the steel pipe is uniform, thereby improving the quality of the steel pipe product.

The two transmission rollers are rotatably installed on the left and right sides of the fixed plate respectively. The rough belt is transmission-connected to the outside of the two transmission rollers. At the same time, the fixed plate drives the rough belt to contact the outer wall of the steel pipe. When the steel pipe moves, the rough belt will be driven to rotate outside the two transmission rollers. The setting of the rough belt reduces the friction between the steel pipe and the fixed plate, thereby avoiding the problem of the fixed plate scratching the surface of the steel pipe when the steel pipe moves.

[0009] According to the above technical solution, the impurity removal device includes a round-mouth frame, a pulley motor, a rotating ring, two spring rods, two inclined plates, and two arc-shaped shovel plates. The round-mouth frame is slidably installed on the left side of the two through-slot plates, and springs are arranged between the top and bottom of the round-mouth frame and the outer wall of the through-slot plates. The pulley motor is fixed on the outer wall of one side of the round-mouth frame. The rotating ring is rotatably installed in the middle part of the round-mouth frame.

The steel pipe will resist the inclined surface of the inclined plate to drive the arc shovel plate to push the spring rod to move away from the center of the swivel. When the steel pipe passes over the inclined surface of the inclined plate, under the action of the spring elastic force corresponding to the spring rod, the spring rod drives the arc shovel plate to stick to the outside of the steel pipe, and then the pulley motor drives the swivel to rotate through the belt, and the swivel drives the spring rod and the arc shovel plate to rotate, and the arc shovel plate scrapes off the metal impurities on the surface of the steel pipe, thereby avoiding the problem of metal impurities adhering to the surface of the steel pipe and affecting the steel pipe straightening operation.

A recess is provided on the top of the arc-shaped shovel plate. The two sticking plates are respectively hinged inside the recess of the arc-shaped shovel plate, and a torsion spring is provided between the sticking plates and the inner walls of the recess of the arc-shaped shovel plate. The two telescopic push rods are respectively fixed on the front and back sides of the inner wall of the swivel, and one end of the telescopic push rod away from the inner wall of the swivel contacts the outer wall of the sticking plates. At the same time, when the arc-shaped shovel plate drives the sticking plates to move away from the center of the swivel, the telescopic push rod pushes the sticking plates to be close to the outer wall of the steel pipe, thereby ensuring that the sticking plates can effectively scrape off the metal impurities on the surface of the steel pipe.

The plurality of triangular blocks are evenly and equidistantly fixed at the middle edge of the right side of the circular mouth frame, the fixed end of the telescopic rod is fixed at the inner wall of the swivel, the arc panel is fixed at the right side of the telescopic end of the telescopic rod, and the triangular block is located on the movement trajectory of the arc panel, and the cleaning brush is fixed on the side of the arc panel close to the center of the circular mouth frame. When the swivel rotates, the telescopic rod will be driven to rotate, and the telescopic rod will drive the arc panel and the cleaning brush to brush off the metal impurities adhered to the surface of the steel pipe, thereby avoiding the secondary adhesion of the metal impurities scraped off by the arc shovel plate and the sticking plate to the surface of the steel pipe, resulting in the problem of embossing defects on the surface of the steel pipe when the movable roller and the fixed plate straighten the steel pipe. At the same time, the inclined surface of the triangular block pushes the arc panel to drive the cleaning brush to dynamically brush off the metal impurities on the surface of the steel pipe, thereby improving the cleaning effect of the cleaning brush on the steel pipe.

The round block pushes the L-shaped rod to drive the knocking rod to knock on the arc panel. The arc panel drives the cleaning brush to vibrate, and the cleaning brush shakes off the metal impurities attached to the surface of the cleaning brush, thereby indirectly improving the cleaning effect of the cleaning brush on the steel pipe.

[0013] According to the above technical solution, the anti-adhesion device includes a plurality of push strips, a U-shaped frame, a swing rod, and a fan plate. The push strips are evenly and equidistantly fixed on the outer wall of the rotating ring, the U-shaped frame is fixed on the top of the round-mouth frame, the swing rod is hinged on the top of the inner wall of the U-shaped frame, and a torsion spring is provided between the swing rod and the U-shaped frame.

During the rotation of the rotating ring, the push strips are driven to rotate, and the push strips push the swing rod and the fan plate to swing. The swing rod drives the fan plate to fan downward, thereby avoiding the problem of metal impurities under the cleaning brush floating and adhering to the outside of the steel pipe.
