Description

Technical Field

[0001] The invention relates to the technical field of roller heat treatment, in particular to a roller heat treatment device and a treatment method. Background Art

[0002] Rollers are the main working parts and tools on the rolling mill that cause continuous plastic deformation of metal. Rollers are mainly composed of three parts: roll body, roll neck and shaft head. Heat treatment is often required during the roll processing.

[0003] A traditional roller heat treatment device places the roller on a sliding seat and then transports the roller to a processing box for heat treatment. However, the hot air in the processing box is not easy to flow, and the roller is stationary, which causes uneven heating during the roller heat treatment process. To solve this problem, in the prior art, a Chinese patent with announcement number CN219972396U discloses a roller heat treatment device. The device can rotate the roller through the arrangement of a sleeve, a sleeve rod and a three-grip chuck, so that the roller surface can be evenly heated inside the processing box. The box door and the placement plate can be linked to facilitate the placement plate to be moved out of the processing box when the box door is opened, which is convenient for placing or removing the roller, thereby improving the use effect of the equipment.

[0004] However, the device has the following shortcomings in actual use: due to the different diameters of the rolls, when the roll support plate actually supports the roll and transports it to the three-claw chuck, the center of the roll and the three-claw chuck may not be in the same straight line, making it difficult to fix the roll. In addition, after the roll is fixed and heat treated, the roll needs to be lifted and cooled by a lifting device, but this fixing method makes it difficult to lift both ends of the roll, the operation time is long, and the work efficiency is reduced. In view of this, the present invention proposes a roll heat treatment device and a treatment method. Summary of the invention

[0021] S1. First, according to the length of the roller, turn the rotating handle of the bidirectional screw to adjust the position of the positioning mechanism, and then place the roller on the positioning mechanism.

[0023] S3, start the motor, the output shaft of the motor drives the toothed rod to rotate, and then the toothed rod drives the bidirectional screw to rotate. As the plug rod is separated from the plug hole, the threaded sleeve rotates accordingly, and then drives the sprocket wheel 1 to rotate. Under the transmission action of the chain, the sprocket wheel 2 drives the supporting wheel to rotate. Under the action of static friction, the roller rotates in the opposite direction, and the positioning wheel rotates accordingly, so that the roller is evenly heated;

[0024] S4. During the rotation of the positioning wheel, the circular shaft drives the eccentric wheel to rotate, and then the connecting rod 1 and the connecting rod 2 move, the swing plate swings to disturb the flow, and accelerates the flow of hot air. The swing of the swing plate drives the hinged rod 2 to move, and then the piston rod reciprocates up and down in the air cylinder, so that the hot air can enter the air cylinder through the one-way air inlet, and then be ejected through the one-way air jet, accelerating the flow of hot air at the bottom of the roller;

[0025] S5. After the rollers are heated, turn off the motor and start the cylinder. The output end of the cylinder drives the baffle to rise and open, and then start the multi-stage electric push rod to push the sliding seat out of the processing box.

[0026] The present invention provides a roller heat treatment device, which has the following beneficial effects:

[0027] (1) Through the use of the positioning mechanism, the motor and the toothed rod, the device can automatically position the rollers of different diameters when in use. After the positioning is completed, the insertion rod rises and disengages from the insertion hole. When the toothed rod is inserted into the toothed rod, the output shaft of the motor rotates, and the supporting wheel can rotate. Under the action of static friction, the roller rotates in the opposite direction, and the positioning wheel follows the rotation, so that the roller is evenly heated. After the heat treatment of the roller is completed, the roller can be easily lifted by moving the sliding seat out, which shortens the operation time and improves the work efficiency.

[0028] (2) By using the positioning mechanism, when the roller is removed after heat treatment, the telescopic end of the elastic telescopic rod drives the connecting frame to reset. Under the action of the hinged rod 1, the positioning wheel is away from the roller and will not block the removal of the roller. At the same time, the insertion rod can be reset. After the insertion rod is inserted into the insertion hole, when the rotating handle of the bidirectional screw is turned, the threaded sleeve will not rotate with the bidirectional screw, so that the sliding block can drive the connecting frame to adjust the position, which is convenient for adapting to rollers of different lengths and improving the use effect of the device.

[0029] (3) Through the use of the positioning mechanism and the disturbance component, the positioning wheel rotates, and then the circular shaft drives the eccentric wheel to rotate, so that the connecting rod 1 and the connecting rod 2 move, so that the swing plate swings to disturb the flow, accelerate the flow of hot air, and further improve the heat treatment effect of the roller.

[0030] (4) Through the use of auxiliary heat treatment components, the swinging plate drives the second hinged rod to move, and then the piston rod moves up and down in the air cylinder, so that the hot air can enter the air cylinder through the one-way air inlet and then be ejected through the one-way air outlet, thereby accelerating the flow of hot air at the bottom of the roller and further improving the heat treatment effect of the roller.

[0047] In the embodiment of the present invention, in order to automatically position the rolling roller, the positioning mechanism 6 includes a bidirectional screw rod 61, a threaded sleeve 63, a positioning assembly 66 and a limit assembly 67. The bidirectional screw rod 61 is rotatably connected to the groove of the sliding seat 5.

The positioning assembly 66 includes an elastic telescopic rod 661, and the bottom of the elastic telescopic rod 661 is fixedly connected to the connecting frame 65. On the inner wall, the top of the telescopic end of the elastic telescopic rod 661 is fixedly connected with a bracket 662, and the bracket 662 is rotatably connected with a supporting wheel 663, and the threaded sleeve 63 is fixedly connected with a sprocket 1 632, and the middle part of the shaft of the supporting wheel 663 is fixedly connected with a sprocket 2 634, and the sprocket 1 632 and the sprocket 2 634 are connected by a chain 633. The outer wall of the bracket 662 is hinged with a hinge rod 1 664, and the end of the hinge rod 1 664 away from the bracket 662 is hinged with an L plate 665, and the end of the L plate 665 away from the hinge rod 1 664 is rotatably connected with a positioning wheel 667, and the L plate 665 is penetrated by a positioning shaft 666 and is rotatably connected with the positioning shaft 666, and the positioning shaft 666 is fixedly connected to the inner wall of the connecting frame 65, and the limiting component 67 includes a round rod 1 664. 71, round rod 1 671 is fixedly connected to the outer wall of the telescopic end of the elastic telescopic rod 661, round rod 1 671 is slidably connected to the straight groove of straight rod 672, straight rod 672 is penetrated by fixed shaft 673 and is rotatably connected to fixed shaft 673, fixed shaft 673 is fixedly connected to the inner wall of connecting frame 65, straight rod 672 is slidably connected to round rod 2 674 in the straight groove at one end away from round rod 1 671, round rod 2 674 is fixed to plug rod 675, limiting sleeve 676 is fixedly connected to the upper side of sliding block 64, plug rod 675 penetrates the outer wall of sliding block 64 and is slidably connected to the outer wall of sliding block 64, plug rod 675 penetrates the limiting sleeve 676 and is slidably connected to the limiting sleeve 676, multiple groups of jacks 631 are provided on the outer wall of threaded sleeve 63, and jacks 63 1 matches with the insertion rod 675.
