Tool steel has high hardness and can maintain high hardness and red hardness at high temperatures, as well as high wear resistance and appropriate toughness. Tool steel is generally divided into carbon tool steel, alloy tool steel and high-speed tool steel. During the processing of tool steel, it needs to be drawn and shaped by a drawing device.

[0003] During the use of the existing drawing device for tool steel processing, since the tool steel is prone to cracks during the drawing process, the existence of cracks affects the use value of the tool steel after drawing. In order to ensure that the tool steel after drawing is intact in all aspects of performance, it is necessary to repair the cracks during the drawing process to ensure its use value. However, the existing drawing device cannot complete this repair during operation, resulting in the lack of use value of the drawing device. Summary of the invention

In order to ensure that the tool steel after drawing is intact in various properties, it is necessary to repair the cracks during the drawing process to ensure its use value. However, the existing drawing device cannot complete this repair during operation.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] By providing an extrusion repair component, when the tool steel is pulled out of the die during the drawing operation, some cracks are prone to appear due to the hard extrusion between the tool steel and the die.

Since cracks are prone to appear in tool steel during the drawing process, the existence of cracks affects the use value of the tool steel after drawing. In order to ensure that the tool steel after drawing is intact in various properties, it is necessary to repair the cracks during the drawing process to ensure its use value. However, the existing drawing device cannot complete this repair scenario during operation.

[0036] In a specific application scenario, during the drawing operation of the tool steel, after it is pulled out of the die, some cracks are prone to appear due to the hard extrusion between the tool steel and the die. The presence of cracks will cause safety hazards to the drawn tool steel during use. In the present invention, after the drawing is completed, during the process of introducing the tool steel into the outer cylinder 501, the drive motor 2 515 is started, and the drive motor 2 515 drives the three extrusion balls inside the adapter ring frame 510 to rotate and extrude the tool steel, so that three spiral grooves are formed on the surface of the tool steel. The formation of the grooves presses the cracks, so that the cracks are gradually eliminated. As the tool steel moves forward, the repair cylinder 502 rotates and repairs the tool steel, and the protruding part of the outer side of the tool steel due to the extrusion of the grooves is gradually squeezed and filled into the grooves, thereby completing the repair of the cracks on the outer side of the tool steel.

[0040] Specifically, common drawing dies are integral structures. During the drawing process, vibrations are generated during the operation of the traction equipment and other equipment.

In the present invention, when two assembly frames 101 are docked, the shock-absorbing spring rod 113 is in a compressed state while the embedded column 110 is inserted into the docking tube 111.

[0045] Working principle: when in use, the tool steel is introduced between the two assembly frames 101. During the drawing process, the drive motor 205 is started. The drive motor 205 drives the inner ring plate 203 to rotate, thereby driving each pressing arc ring 204 to rotate and press different positions of the tool steel, thereby accelerating the movement of the tool steel toward the die hole with the smallest diameter.

After moving to the specified length, the electric telescopic rod 1 105 is reset first, and then the electric telescopic rod 2 1108 is reset. Then, the electric telescopic rod 1 1105 drives the dynamic clamping frame 1102 to clamp the tool steel again. After the fixed-length drawing component 11 reciprocates, the drawn tool steel is gradually introduced into the outer cylinder 501, and the drive motor 2 515 is started. The drive motor 2 515 drives the three extrusion balls inside the adapter ring frame 510 to rotate and extrude the tool steel, so that three spiral grooves are formed on the surface of the tool steel. The formation of the grooves presses the cracks, so that the cracks are gradually eliminated. As the tool steel moves forward, the repair cylinder 502 rotates and repairs the tool steel, and the protruding part of the outer side of the tool steel due to the extrusion of the grooves is gradually squeezed and filled into the grooves. During the repair process, the oscillation ball 504 knocks on the repair cylinder 502, so that the tool steel inside the repair cylinder 502 has an oscillation effect, which accelerates the repair process.
