Description

Technical Field

[0001] This invention relates to the field of martensitic valve steel technology, and more specifically to a bar processing equipment for hot extrusion of martensitic valve steel. Background Technology

[0002] The microstructure of martensitic steel is almost entirely martensite. It is mainly transformed from austenitic to lath martensite through rapid quenching at high temperatures, which can be achieved through hot rolling and cold rolling. Martensitic steel has high tensile strength and requires tempering to improve its plasticity, ensuring sufficient formability even at such high strength. It is the highest strength grade of commercially available high-strength steel. Hot extrusion involves heating the metal material to the hot forging temperature and then extruding it; that is, extrusion is performed by heating the billet to a temperature above the recrystallization temperature of the metal before extrusion.

[0003] In the prior art, after martensitic valve steel bars are produced by hot extrusion equipment, they are usually transported on conveying equipment. However, most of the conveying equipment is a rotating cylinder. When the martensitic valve steel bar moves on the cylinder, since it is also round, the bar may shift its position during the movement. This makes it difficult to correct the conveying position of the martensitic valve steel bar, which may cause it to fall off the conveying equipment. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a processing equipment for hot extrusion bars of martensitic valve steel. This solves the problem that, typically, after martensitic valve steel bars are produced by hot extrusion equipment, they are transported on a conveying device. However, most conveying devices are rotating cylinders. When the martensitic valve steel bars move on the cylinder, because they are also circular, their position may shift during movement. This makes it difficult to correct the conveying position of the martensitic valve steel bars, potentially causing them to fall off the conveying device.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] A processing equipment for hot extrusion bars of martensitic valve steel includes: a conveyor table with two limiting grooves on its top surface and several conveying columns arranged inside the limiting grooves; and a processing correction assembly disposed on both sides of the conveyor table for position correction during the processing and conveying of the hot martensitic valve steel bars. The processing correction assembly includes: several movable holes, which are respectively opened on both sides of the conveyor table; a mounting column is fixedly installed at one end of each conveying column, and the mounting column is movably sleeved with the movable hole; every two conveying columns form a group, and a connecting column is fixedly installed between each group of conveying columns; several connecting holes are opened on one side of the limiting grooves, and the connecting columns are movably sleeved with the connecting holes; a pulley is fixedly installed at one end of each mounting column, and the outer circular wall of the pulley is provided with a transmission... A conveyor belt is used. A mounting plate is fixedly installed on one side of the conveyor platform. A first fixing hole is opened on one side of the mounting plate. A stepper motor is fixedly sleeved on the inner circular wall of the first fixing hole. The stepper motor is fixedly installed to one end of the pulley located on the left side. A PLC controller is provided on one side of the mounting plate. The PLC controller is electrically connected to the stepper motor. A mounting platform is fixedly installed on one side of the conveyor platform. An auxiliary column is provided inside the mounting platform. A fixing groove is opened on the top surface of the conveyor platform. A second drive motor is fixedly installed on the inner circular wall of the fixing groove. A rotating column is fixedly installed on the top surface of the drive shaft of the second drive motor. Two correction plates are fixedly installed on the outer circular wall of the rotating column. The PLC controller is electrically connected to the second drive motor. A limit groove is opened on the outer circular wall of the conveyor column.

The first drive motor is electrically connected to the PLC controller.

[0009] By adopting the above technical solution, after the martensitic valve steel hot bar is removed from the hot extrusion equipment, it will fall onto the surface of the auxiliary column. Then, the operator starts the first drive motor, and the rotation of the drive shaft of the first drive motor will drive the auxiliary column to rotate, thereby moving the martensitic valve steel hot bar, which facilitates the forward movement of the martensitic valve steel hot bar.

[0010] Preferably, the top surface of the conveyor is provided with an auxiliary groove, and the two sides of the interior of the auxiliary groove are respectively provided with rotating grooves.

[0015] By adopting the above technical solution, the two forming wheels are positioned close to each other. When the hot martensitic valve steel bar moves to the middle of the two forming wheels, it will drive the forming wheels to rotate. Through the rotation of the forming wheels on the surface of the hot martensitic valve steel bar, it is convenient to shape the hot martensitic valve steel bar at high temperature and make it more round.

[0040] Example 4

[0041] Based on the above embodiments 1, 2 or 3, and referring to Figure 1 , Figure 2 and Figure 7 The top and bottom surfaces of the fixed block 28 are respectively fixedly installed with sliders 29.

The surface of the conveying column 3 is coated with wear-resistant coating 39.

[0042] Working principle: Please refer to Figures 1-7 As shown, through the setting of the correction plate 22, when the martensitic valve steel hot bar is produced by the hot extrusion equipment, since the martensitic valve steel hot bar is cylindrical, it is caused to fall onto the top surface of the conveyor table 1 after being extruded by the hot extrusion equipment. Specifically, the martensitic valve steel hot bar is placed at the center position of the conveyor table 1. Before being completely extruded from the hot extrusion equipment, the martensitic valve steel hot bar will continue to move forward. After moving continuously on the top surface of the conveyor table 1, the martensitic valve steel hot bar will approach the correction plate 22. Inside, the operator uses the PLC controller 13 to control the second drive motor 20, which rotates the drive shaft of the second drive motor 20, causing the rotating column 21 and the correcting plate 22 to rotate. When the hot martensitic valve steel bar contacts the correcting plate 22, the rotation of the correcting plate 22 pushes the hot martensitic valve steel bar from one side, thereby changing the direction of movement of the hot martensitic valve steel bar. The position of the hot martensitic valve steel bar will then tilt to the right or left, thus changing the direction of movement of the hot martensitic valve steel bar. As the hot bar continues to move, it falls into the confinement groove 2. Then, the operator starts the stepper motor 12. The drive shaft of the stepper motor 12 rotates, driving the first pulley 8 to rotate, which in turn drives multiple pulleys 8 via the transmission belt 9. This causes the conveyor column 3 to rotate. The rotation of the conveyor column 3 moves the martensitic valve steel hot bar that has fallen into the confinement groove 2, facilitating its transfer. Because the martensitic valve steel hot bar is cylindrical, it will... The hot martensitic valve steel bar is moved and falls into the limiting groove 23. The limiting groove 23 limits the hot martensitic valve steel bar, preventing displacement during transmission. The correcting plate 22 pushes the hot martensitic valve steel bar into the limiting groove 2, and then it is conveyed by the conveying column 3 to enter the limiting groove 23 for restriction. This facilitates the position correction of the moving hot martensitic valve steel bar, ensuring a uniform transmission position and preventing positional deviation during movement.

[0043] After the hot martensitic valve steel bar is removed from the hot extrusion equipment via the auxiliary column 17, it will fall onto the surface of the auxiliary column 17. Then, the operator starts the first drive motor 16. The drive shaft of the first drive motor 16 rotates, which drives the auxiliary column 17 to rotate, thereby moving the hot martensitic valve steel bar and facilitating the forward movement of the hot martensitic valve steel bar.

[0044] With the auxiliary groove 24 provided, when the hot martensitic valve steel bar falls into the center of the conveyor table 1, it will drive the rotating column 26 to rotate during the movement, thereby reducing the planar contact between the hot martensitic valve steel bar and the conveyor table 1.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
