A flame spraying device for a cast roll

Abstract

This utility model discloses a flame spraying device for anti-sticking rollers of casting and rolling mills, relating to the field of aluminum-titanium alloys. It includes a support and stabilizing frame and a movable flame nozzle. A first rotating frame is mounted on the side of the support and stabilizing frame, and an engaging sliding mechanism for moving the movable flame nozzle back and forth is installed inside the first rotating frame. The engaging sliding mechanism includes a contact transmission plate, which is fixedly installed inside the support and stabilizing frame. When heating both ends of the self-driven roller is required, this flame spraying device for anti-sticking rollers of casting and rolling mills directly starts a reciprocating motor, causing the extended fixing rod to drive the meshing rack through a fixed integrated gear. This allows the two sets of movable flame nozzles to reciprocate and heat the ends of the self-driven roller. This design prevents the edges of the cast plate from sticking to the roller during the production of high-alloy products from aluminum alloy casting and rolling, improving product quality. Furthermore, the edge heating operation is more uniform, preventing the edges of the cast plate from sticking together.

Description

Technical Field

[0001] This utility model relates to the field of aluminum-titanium alloy technology, specifically to a flame spraying device for anti-sticking rollers of casting and rolling mills. Background Technology

[0002] Hot pressing is a process of heating and pressing a pre-formed fiberboard blank to produce fiberboard with certain mechanical strength and water resistance. Whether it is wet-process production of rigid or semi-rigid boards, or dry-process production of rigid or medium-density fiberboard, hot pressing is necessary to produce the final product.

[0003] The existing flame spraying method cannot meet the needs of accelerated production because the total amount of carbon black adhering to the surface of the casting roll is relatively small. It will cause serious sticking to the roll and plate due to the difficulty in demolding the casting plate. This can lead to material scrap and loss or even damage to the production equipment. In addition, it is inconvenient to adjust.

[0004] To overcome the above defects, the prior art (publication number: CN219772220U, Chinese patent application date: 2023-09-29) discloses a flame spraying device for preventing edge sticking of the roller in a casting and rolling mill. The roller shaft is provided with rotating grooves on both sides, and the rotating grooves are fixed on the frame. A support frame is fixed on the outer wall of the left side of the frame, and a motor is fixed on the support frame. One end of the output shaft of the motor is connected to a rotating shaft, and the other end of the rotating shaft is inserted into the rotating groove and connected to the roller shaft. A first nozzle is provided in the middle of the connecting rod. The flame spraying device for preventing edge sticking of the casting and rolling mill uses a Y-shaped diverter to evenly distribute natural gas into two sets of second nozzles. The first nozzle is a long plate shape. By using two different nozzles to perform all-round thermal spraying on the roller shaft, the overall lubrication of the roller shaft is improved, thus preventing the casting and rolling plate from sticking to the roller. The second nozzle of this device forms a movable rotating structure through a rotating head and a connecting head, which facilitates the adjustment of the angle of the second nozzle. In addition, there are spiral rings on the second nozzle, which makes the flame spraying range of the second nozzle more precise.

[0005] While the existing design can solve the above problems, it is prone to sticking to the rollers at the edges of the cast and rolled plates when producing high-alloy products from aluminum alloy casting and rolling, which affects product quality. Furthermore, the edge heating operation is not uniform enough, resulting in insufficient anti-sticking effect. At the same time, during the conveying of aluminum alloy plates, impurities generated during metal processing can cause slippage between aluminum alloy plates, affecting processing efficiency. In addition, impurities can affect manual processing operations. Utility Model Content

[0006] The purpose of this utility model is to provide a flame spraying device for anti-sticking rollers of casting and rolling mills, so as to solve the problems mentioned in the background art, such as the easy sticking of the edges of the cast and rolled plate when producing high alloy products from aluminum alloy casting and rolling, which affects product quality, and the uneven heating of the edge operation, resulting in insufficient anti-sticking effect. At the same time, during the conveying of aluminum alloy plates, impurities generated during metal processing will detach, causing slippage between aluminum alloy plates and affecting processing efficiency. Furthermore, impurities will affect manual processing operations.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a flame spraying device for anti-sticking rollers of a casting and rolling mill, comprising a support and stabilizing frame and a movable flame nozzle. A first rotating frame is installed on the side of the support and stabilizing frame, and an engaging sliding mechanism for moving the movable flame nozzle back and forth is installed inside the first rotating frame. The engaging sliding mechanism includes a contact transmission plate, which is fixedly installed inside the support and stabilizing frame. A processed alloy plate is installed on the upper surface of the contact transmission plate, and a reciprocating motor is installed on the top of the first rotating frame. A transverse rotating frame is installed on the upper surface of the contact transmission plate, and an abutment transmission mechanism for rotating a cleaning anti-sticking brush is installed inside the transverse rotating frame.

[0008] Furthermore, the abutment transmission mechanism includes an auxiliary rolling frame, which is fixedly installed on the left and right sides of the support and stabilizing frame. The lower surface of the auxiliary rolling frame is in contact with the upper surface of the processed alloy plate, and a lifting support frame is installed inside the support and stabilizing frame.

[0009] Furthermore, the top of the lifting support frame abuts against the lower surface of the processed alloy plate, and the cleaning and anti-stick brush is rotatably installed inside the transverse rotating frame. The rotation trajectory of the cleaning and anti-stick brush is in contact with the movement trajectory of the processed alloy plate, and a connecting transmission belt is installed on the outer surface of the extension fixing rod.

[0010] Furthermore, an extension fixing rod is installed on the outer surface of the output end of the reciprocating motor, and a fixed integral gear is installed on the outer surface of the center position of the extension fixing rod. Sliding limit frames are installed on the left and right sides of the support and stabilizing frame, and a movable flame nozzle is installed inside the sliding limit frame.

[0011] Furthermore, a meshing rack is installed on the top of the movable flame nozzle, and a fixed integral gear meshes with the meshing rack. The movable flame nozzle slides laterally along the inside of the sliding limit frame, and a self-driving roller is installed inside the first rotating frame.

[0012] Furthermore, the outer surface of the self-driving roller is in contact with the upper surface of the processed alloy plate, and the processing position of the moving flame nozzle corresponds to the left and right ends of the self-driving roller. The outer surface of the fixed integral gear contacts the upper surface of the meshing rack to form a meshing structure, and the interior of the sliding limit frame contacts the outer surface of the moving flame nozzle to form a sliding structure.

[0013] Furthermore, the other end of the inner surface of the connecting transmission belt is fitted to the outer surfaces of both ends of the cleaning anti-stick brush, and the inner surface of the transverse rotating frame contacts the outer surface of the cleaning anti-stick brush to form a sliding structure. Moreover, the extension fixing rod contacts the outside of the cleaning anti-stick brush through the inside of the connecting transmission belt to form a transmission structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When the flame spraying device for the anti-sticking roller of the casting and rolling mill needs to heat both ends of the self-driven roller, the reciprocating motor is directly started so that the extended fixing rod drives the meshing rack through the fixed integrated gear, so that the two sets of moving flame nozzles at the front and rear will reciprocate the heating operation at the end of the self-driven roller. This design prevents the edge of the casting plate from sticking to the roller when producing high alloy products from aluminum alloy casting and rolling, thus improving product quality. In addition, the edge heating operation is more uniform, resulting in a better anti-sticking effect.

[0015] Furthermore, after the extension fixing rod is activated, the externally attached connecting transmission belt is driven synchronously. At this time, the connecting transmission belt will drive the cleaning anti-stick brush synchronously, and the rotation of the cleaning anti-stick brush will rotate and clean the processed alloy plate. This design ensures that the transmission effect between aluminum alloy plates will not slip and affect the processing efficiency, and impurities will be cleaned in time.

[0016] Furthermore, the internal fixed lifting support frame of the support and stabilizing frame lifts the lower part of the processed alloy plate upward, and the auxiliary rolling frame on the outside of the support and stabilizing frame makes the conveying operation more stable.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Example 1: Please refer to Figures 1-6 The present invention provides the following technical solution: a flame spraying device for anti-sticking rollers of a casting and rolling mill, comprising a support and stabilizing frame 1 and a movable flame nozzle 11. A first rotating frame 2 is installed on the side of the support and stabilizing frame 1, and a meshing sliding mechanism for moving the movable flame nozzle 11 back and forth is installed inside the first rotating frame 2. The meshing sliding mechanism includes a contact transmission plate 9, and the contact transmission plate 9 is fixedly installed inside the support and stabilizing frame 1. A processing alloy plate 13 is installed on the upper surface of the contact transmission plate 9, and a reciprocating motor 4 is installed on the top of the first rotating frame 2. A transverse rotating frame 10 is installed on the upper surface of the contact transmission plate 9, and a contact transmission mechanism for rotating a cleaning anti-sticking brush 16 is installed inside the transverse rotating frame 10.

[0026] like Figure 1 , Figure 2 , Figure 3The technical solution shown addresses the problems of edge sticking during the production of high-alloy products from aluminum alloy casting and rolling, which affects product quality, and uneven heating during edge heating, resulting in insufficient anti-sticking effect. The solution discloses: an extension fixing rod 5 is mounted on the outer surface of the output end of the reciprocating motor 4, and a fixed integrated gear 6 is mounted on the outer surface of the center position of the extension fixing rod 5; sliding limit frames 8 are mounted on the left and right sides of the support and stabilizing frame 1, and a movable flame nozzle 11 is installed inside the sliding limit frame 8; the top of the movable flame nozzle 11 is equipped with a meshing... The rack 7 and the fixed integrated gear 6 mesh with each other. The movable flame nozzle 11 slides laterally along the inside of the sliding limit frame 8. The first rotating frame 2 is equipped with a self-driving roller 3. The outside of the self-driving roller 3 is in contact with the upper surface of the processed alloy plate 13. The processing position of the movable flame nozzle 11 corresponds to the left and right ends of the self-driving roller 3. The outer surface of the fixed integrated gear 6 contacts the upper surface of the meshing rack 7 to form a meshing structure. The inside of the sliding limit frame 8 contacts the outer surface of the movable flame nozzle 11 to form a sliding structure.

[0027] When it is necessary to perform anti-sticking processing on both ends of the self-driven roller 3, firstly, the self-driven roller 3, which is fixedly installed inside the first rotating frame 2, is started to rotate. This causes the self-driven roller 3 to synchronously drive the processing alloy plate 13 in contact with its lower end. As it is driven, the processing alloy plate 13 will slide along the upper surface of the bonding transmission plate 9, which is fixedly installed inside the support and stabilizing frame 1. At this time, the reciprocating motor 4, which is fixedly installed on the top of the first rotating frame 2, is started again. This causes the reciprocating motor 4 to synchronously rotate the extension fixing rod 5, which is fixedly installed on the outer surface of its output end, and the fixed integrated gear 6. The rotation of the fixed integrated gear 6... The moving part engages with the meshing rack 7, which is mounted against the lower surface, and drives it. As the meshing rack 7 is driven, it synchronously drives the movable flame nozzle 11, which is fixedly mounted on the lower surface. The movable flame nozzle 11 slides laterally along the sliding limit frame 8, which is fixedly mounted on both sides of the support and stabilizing frame 1. During the movement, the movable flame nozzle 11 continuously heats the two ends of the self-driving roller 3, preventing the processed alloy plate 13 from sticking. The reciprocating motor 4 drives the extension fixing rod 5 to reciprocate in both directions, making the heating work more uniform.

[0028] Example 2: Figure 4 , Figure 5 , Figure 6The technical solution shown addresses the problem that during the conveying of aluminum alloy sheets, impurities generated during metal processing cause slippage and affect processing efficiency, and these impurities also interfere with manual processing. The solution discloses an abutment transmission mechanism including an auxiliary rolling frame 12, which is fixedly installed on the left and right sides of a support and stabilizing frame 1. The lower surface of the auxiliary rolling frame 12 is in contact with the upper surface of the processed alloy sheet 13. Furthermore, a lifting support frame 14 is installed inside the support and stabilizing frame 1, with its top touching the processed alloy sheet 13. The lower surfaces of the two parts 3 abut against each other, and the cleaning anti-stick brush 16 is rotatably installed inside the transverse rotating frame 10. The rotation trajectory of the cleaning anti-stick brush 16 is in contact with the movement trajectory of the processing alloy plate 13. The outer surface of the extension fixing rod 5 is equipped with a connecting transmission belt 15. The other end of the inner surface of the connecting transmission belt 15 is in contact with the outer surfaces of the two ends of the cleaning anti-stick brush 16. The inner surface of the transverse rotating frame 10 and the outer surface of the cleaning anti-stick brush 16 are in contact to form a sliding structure. The extension fixing rod 5 is in contact with the outside of the cleaning anti-stick brush 16 through the inside of the connecting transmission belt 15 to form a transmission structure.

[0029] When the reciprocating motor 4 drives the extension fixing rod 5 to rotate, the connecting transmission belt 15, which is attached to the outer surface of the extension fixing rod 5, will be driven to roll synchronously. Since the other side of the inner surface of the connecting transmission belt 15 is also attached to the outer surfaces of the left and right sides of the cleaning anti-stick brush 16, the cleaning anti-stick brush 16 will be driven to rotate continuously and stably in a circular motion along the inside of the transverse rotating frame 10. Since the transverse rotating frame 10 is fixedly installed on the left and right sides of the support and stabilizing frame 1, the rotation of the cleaning anti-stick brush 16 is more stable. At the same time, as the cleaning anti-stick brush 16 enters... During rotation, the cleaning and anti-stick brush 16 continuously contacts the upper surface of the processed alloy plate 13, causing impurities generated by the processed alloy plate 13 to be swept outward, improving the transmission efficiency between the self-driven roller 3 and the processed alloy plate 13. At the same time, after the processed alloy plate 13 is transmitted forward, the lower end of the processed alloy plate 13 is lifted upward by the lifting support frame 14 fixedly installed inside the support and stabilizing frame 1. Meanwhile, the upper surface of the processed alloy plate 13 is subjected to downward limiting auxiliary transmission through the auxiliary rolling frames 12 fixedly installed on both sides of the support and stabilizing frame 1, which improves the stability of the equipment.
