Description

Technical Field

[0001] This utility model relates to the field of rolling mill technology, and in particular to a high-speed steel rolling mill roll. Background Technology

[0002] High-speed steel is a high-quality alloy steel with excellent wear resistance, hardness and heat resistance. It is often used in the manufacture of high-quality rolls. High-speed steel undergoes a series of heat treatment processes to improve its hardness, wear resistance and heat resistance. Through appropriate heat treatment, high-speed steel can better withstand the high temperature and pressure encountered during the use of rolls.

[0003] Different types of high-speed steel rolls can produce different textures, patterns, or shapes on the product surface during the rolling process, thereby meeting customers' requirements for product appearance quality. However, when adjusting the rolling pattern on the outer wall of different high-speed steels, it is very inconvenient to replace the rolls. Therefore, we propose a high-speed steel roll to solve the existing problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a high-speed steel roll.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-speed steel rolling roll, comprising a roll sleeve, a first motor, a base, a second motor, and a rolling roll. Two sets of symmetrically distributed supports are arranged on the upper end of the base. A second motor is installed at one end of each support. A rolling roll rotatably mounted inside the support is installed at the output end of the second motor. A third symmetrically distributed support is arranged on the upper end of the base. A first support is positioned above the third support. The second support is connected to both the first and third supports. A roll sleeve is fitted onto the outer wall of the rolling roll. Rotary seats are rotatably fitted onto the outer sides of both sides of the roll sleeve. A first motor is installed on one inner wall of both the third and first supports. A screw rotatably mounted inside the third and first supports is installed at the output end of the first motor. A nut threaded onto the screw is rotatably fitted onto the outer wall of the screw.

[0006] When using a high-speed steel roll in this solution, the hydraulic rod drives the first support to move longitudinally, and the second support, which is fixed to the first support, moves longitudinally, thereby driving the rolling roll inside the second support to adjust its height. When the second motor operates, it drives the rolling roll to rotate. Because the rolling roll is slidably sleeved on the outer wall of the slider through the guide rails distributed in a ring array, the rotational force is applied to the roll sleeve, and the roll sleeve rotates relative to each other, thus rolling the high-speed steel that passes through.

[0007] When the motor operates, it drives the screw to rotate. The nut, which is threaded onto the screw, slides on the outer wall of the guide rod through a sliding sleeve. This guides the nut to move, causing the rotating seat to move laterally. This adjusts the position of the roller sleeve on the outer wall of the rolling roll. Because the rotating seat is mounted on the roller sleeve, the rotational force of the roller sleeve does not act on the nut. The nut pushes the rotating seat to move stably, thereby adjusting the position of the roller sleeve. The outer wall of the roller sleeve has multiple sets of different rolling patterns, corresponding to the high-speed steel passing through it. The rolling pattern on the outer wall is adjusted during the high-speed steel rolling process.

[0008] Preferably, the outer wall of the rolling roll is provided with guide rails arranged in a circular array, and the inner wall of the roll sleeve is provided with sliders arranged in a circular array. The guide rails are slidably sleeved on the outer wall of the sliders. The rolling roll slides on the outer wall of the sliders via the guide rails, providing lateral sliding support to the roll sleeve. At the same time, the rotational force is effectively applied to the roll sleeve, driving the roll sleeve to rotate.

[0009] Preferably, one end of the support bracket is provided with a hydraulic rod, and the telescopic end of the hydraulic rod is provided with a connecting plate connected to the support bracket. When the hydraulic rod operates, it drives the connecting plate to move longitudinally, thereby adjusting the height of the support bracket.

[0010] Preferably, the hydraulic rod is connected to the support frame three via a mounting block. A guide plate is provided on the inner wall of the support frame one, and a slide block is provided at one end of the support frame three. The guide plate is slidably installed inside the slide block. The mounting block fixes the hydraulic rod and connects it to the support frame three. When the support frame one moves longitudinally, it slides within the slide block via the guide plate, thus achieving longitudinal sliding guidance.

[0011] Preferably, the outer wall of the nut is provided with a sliding sleeve, and a guide rod fixed inside the first bracket and the second bracket is slidably inserted into the sliding sleeve. The nut slides laterally on the outer wall of the guide rod through the sliding sleeve, thereby obtaining lateral sliding guidance.

[0012] Preferably, a reinforcing rib is provided at the connection between the second bracket and the first and third brackets, and a reinforcing rib is provided between the third bracket and the base. The connection between the first and second brackets is reinforced by the reinforcing rib, and the connection between the third bracket and the base is reinforced by the reinforcing rib.

[0013] Preferably, the roller sleeve has a first type of ball bearing arranged in a circular array rotatably mounted on both ends of the roller sleeve, and a second type of ball bearing rotatably mounted on both outer walls of the roller sleeve. The rotating seat reduces the resistance of the roller sleeve to the rotating seat when it supports the rotation of the roller sleeve through the first and second types of ball bearings.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. The pressing structure of this utility model for high-speed steel includes a rolling roll that rotates relative to the rolling roll and a roll sleeve that drives the rolling roll to rotate. The length of the roll sleeve is three times that of the rolling roll. During use, by adjusting the position of the roll sleeve, the texture of different sections of the outer wall of the roll sleeve corresponds to the high-speed steel during rolling. This allows for the pre-installation of textures that are not commonly processed but are required for special applications. When the rolling texture of the high-speed steel changes, the rolling equipment can be easily adjusted, avoiding tedious and time-consuming adjustment time. The rolling equipment for high-speed steel is flexible in use. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-Figure 5As shown, the present invention proposes a high-speed steel rolling mill roll, including a roll sleeve 2, a motor 7, a base 10, a motor 15, and a rolling mill roll 17. The upper end of the base 10 is provided with two sets of symmetrically distributed supports 11. Each support 11 is provided with a motor 15 at one end. The output end of the motor 15 is provided with a rolling mill roll 17 rotatably installed inside the support 11. The upper end of the base 10 is provided with symmetrically distributed supports 13. Support 1 is provided above the support 13. Support 1 is connected to support 11 and support 13. The outer wall of the rolling mill roll 17 is sleeved with a roll sleeve 2. Rotating seats 12 are rotatably sleeved on both sides of the outer side of the roll sleeve 2. Motor 7 is provided on one side of the inner wall of support 13 and support 11. The output end of motor 17 is provided with a screw 3 rotatably installed inside support 13 and support 11. The outer wall of the screw 3 is rotatably sleeved with a nut 8 threadedly installed on the screw 3.

[0024] The outer wall of the rolling roll 17 is provided with guide rails 16 arranged in a ring array, and the inner wall of the roll sleeve 2 is provided with sliders 14 arranged in a ring array. The guide rails 16 are slidably sleeved on the outer wall of the sliders 14.

[0025] The outer wall of the nut 8 is provided with a sliding sleeve 9, and a guide rod 4 fixed inside the bracket 1 and bracket 2 11 is slidably inserted into the sliding sleeve 9.

[0026] A reinforcing rib 18 is provided at the connection between bracket 2 11 and bracket 11 and bracket 3 13, and a reinforcing rib 18 is provided between bracket 3 13 and base 10.

[0027] Roller sleeve 2 has ball bearings 21 arranged in a ring array on both ends of the roller sleeve 2 and ball bearings 22 rotatably installed on both outer walls of the roller sleeve 2.

[0028] Based on the implementation steps of Example 1: the cooperation of structures such as motor 7 and screw 3 enables the adjustment of the outer wall texture of the high-speed steel roll. Through flexible device design and mechanical operation, the position and outer wall texture of the rolling roll 17 can be adjusted quickly and accurately, thereby meeting the customer's requirements for product appearance quality, improving production efficiency, and completing the process adjustment without replacing the rolling roll 17, reducing the inconvenience caused by replacing the roll and making the operation process more convenient.

[0029] like Figure 1-Figure 5 As shown, compared with Embodiment 1, the high-speed steel roll proposed in this utility model further includes: a hydraulic rod 6 is provided at one end of the support 3 13, and a connecting plate 5 connected to the support 1 is provided at the telescopic end of the hydraulic rod 6;

[0030] The hydraulic rod 6 is connected to the bracket 13 via a mounting block. The inner wall of the bracket 1 is provided with a guide plate 20, and one end of the bracket 13 is provided with a slide block 19. The guide plate 20 is slidably installed inside the slide block 19.

[0031] In this embodiment, the hydraulic rod 6 drives the connecting plate 5 to adjust its height, and the bracket 1 links the bracket 2 11, thereby driving the rolling roll 17 and the roll sleeve 2 to adjust their height. The heat-treated high-speed steel is subjected to pressure rolling through the relatively rotating roll sleeve 2. However, the thickness of the high-speed steel is different in the processing technology. Different thicknesses of metal materials require different rolling gaps. Therefore, by adjusting the gap of the roll sleeve 2, the equipment can adapt to different requirements and meet the processing needs of high-speed steel of different thicknesses.
