Description

Technical Field

[0001] This utility model relates to the field of rolling mill processing, specifically a heat treatment device for rolling mill processing. Background Technology

[0002] Rolls are core components in the metallurgical rolling production field. They are mainly used to apply pressure to metal billets during the rolling process, causing the billets to undergo plastic deformation and ultimately be rolled into various metal profiles such as steel plates, steel sections, and steel pipes. They are usually cylindrical in shape and consist of three parts: the roll body, the roll neck, and the shaft head.

[0003] The overall production process of rolling mill rolls involves several key steps, including raw material smelting, forging, rough machining, heat treatment, and finish machining. Among these, the quenching process in the heat treatment stage is particularly important. Currently, the industry commonly uses high-frequency induction heating equipment for the surface quenching of rolling mill rolls. Before quenching the rolling mill rolls, workers typically use a metal composite frame to cover the outside of the roll body. Utilizing the structural stability of the frame, the rolling mill rolls are smoothly lifted to the designated working area of ​​the high-frequency induction heating equipment using a lifting device. After the rolling mill rolls are lifted to the high-frequency induction heating equipment, they need to be accurately placed on the pre-set fixed columns of the equipment. At this time, workers need to support and adjust the position of both ends of the rolling mill rolls to ensure that the pre-set positioning grooves on both ends of the rolling mill rolls are aligned with the fixed columns on the heating equipment. Only after precise alignment can the fixed columns be inserted into the grooves from the upper and lower ends of the rolling mill rolls, forming a stable clamping and fixing of the rolling mill rolls, ensuring that the rolling mill rolls will not shift during rotation.

[0004] However, for some medium and small hollow rolls that are longer, there are obvious inconveniences in aligning the top groove with the fixed column. Because the roll is relatively high, the staff cannot directly observe the corresponding angle between the top groove and the fixed column. They need to use ladders or other auxiliary tools to climb up and observe, and then adjust the position of the roll. This operation method is not only inefficient, but also makes it difficult to achieve a precise alignment between the roll and the fixed column, which can easily lead to the fixed column not being able to be successfully embedded in the groove. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a heat treatment device for rolling mill processing to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat treatment device for processing rolls, comprising a fixed plate, a sliding plate on one side of the fixed plate, fixed columns installed at the bottom of the sliding plate and on one side of the bottom of the fixed plate, a fixed block fixed at one end of the fixed plate, a frame connected inside the fixed block, first clamping plates fixed at the top and bottom of one end of the frame, a connecting column installed on one side of the frame, with both ends of the connecting column penetrating the frame, a connecting plate fixed at the top and bottom of the connecting column, a second clamping plate installed at one end of the connecting plate, a heating coil on one side of the fixed plate, a roll placed above the heating coil, and grooves formed at both ends of the roll.

[0007] By adopting the above technical solution, the problem of aligning the grooves at both ends of the roll with the fixed columns on the heat treatment device is solved. First, the frame is flipped to the front position of the fixed plate, and the frame is fixed in position using a fixing rod. Then, the second clamping plate is moved away from the first clamping plate, so that the lifting device can lift the roll and the lifting plate to the position above the heating ring. Then, the second clamping plate is moved towards the first clamping plate, so that the second clamping plate pushes the roll, making the roll contact the inner wall of the first clamping plate. After the second clamping plate has finished pushing, the personnel can control the lifting device to move the roll towards the frame, so that the roll is tightly fitted with the inner walls of the first and second clamping plates, thereby completing the positioning of the roll and the fixed column.

[0008] The present invention is further configured such that a lifting plate is sleeved on the outer wall of the roller, a fixed frame plate is installed on the top of the lifting plate and the fixed frame plate is fixedly connected by bolts, a rotating column is fixed at the bottom of the lifting plate, a support rod is connected to the end of the rotating column, and a pin is installed at the end of the support rod.

[0009] Preferably, when one end of the support rod is fixed to one side of the lifting plate by a pin, the support rod supports the top part of the roll, and the fixing frame plate limits and fixes one end of the roll, so that personnel can lift the roll by using a lifting tool.

[0010] The present invention is further configured such that the top of the fixing block is provided with an insertion hole, the outer wall of the frame is provided with a fixing hole, the inside of the insertion hole is provided with a fixing rod, and the outer wall of the frame is provided with a handle.

[0011] Preferably, when the frame is flipped to the front of the fixing plate, the operator inserts the fixing rod into the fixing block. The fixing rod passes through the connection part of the frame, thereby fixing the frame.

[0012] The present invention is further provided that a baffle is provided on one side of the inside of the fixing block.

[0013] Preferably, when the frame is flipped so that the frame wall contacts the baffle, the frame is flipped to the front position of the fixed plate.

[0014] The present invention is further configured such that a slide rail is provided on one side of the fixed plate, a motor is installed on the top of the fixed plate, one end of the motor is connected to a lead screw, and the lead screw passes through the slide plate.

[0015] Preferably, the operator can control the operation of the motor through the control box on the control device. The motor can drive the slide plate to rise and fall vertically through the lead screw, so that the fixing column at the bottom of the slide plate is inserted into the groove at one end of the roller.

[0016] The present invention is further configured such that limit blocks are fixed at both ends of the connecting column, and the inner wall diameters of the first clamping plate and the second clamping plate are equal to the outer diameter of the roll.

[0017] Preferably, when a person pulls the connecting column away from the first clamping plate, the connecting column cannot be pulled when the limiting block contacts the frame wall.

[0018] The present invention is further configured such that a handle is fitted on the outer wall of the connecting column, a limiting post is fixed on the outer wall of the handle, a connecting rod is connected inside the limiting post, inserts are installed at both ends of the connecting rod, and through holes are opened at both ends of the connecting column.

[0019] Preferably, when the connecting plate on one side of the second clamping plate presses the lifting plate on the outer wall of the roll against one end of the first clamping plate, the operator can manually adjust the connecting rod so that the insert is inserted into the through hole at the end of the connecting column, thereby completing the fixing of the second clamping plate.

[0020] The present invention is further configured such that a support plate is fixed to the outer wall of the connecting column, and the support plate is located below the handle.

[0021] Preferably, when the insert is inserted into the through hole, the handle will descend to the top of the support plate due to its own weight, and the support plate will support and limit the handle.

[0022] In summary, the present invention has the following main advantages: 1. This utility model solves the problem of the difficulty in aligning the grooves at both ends of the roll with the fixed columns on the heat treatment device by setting up a frame, a first clamping plate, a second clamping plate, a fixing rod, and a connecting plate. First, the frame is flipped to the front position of the fixing plate, and the frame is fixed in position using the fixing rod. Then, the second clamping plate is moved away from the first clamping plate, so that the lifting device can lift the roll and the lifting plate to the position above the heating coil. Then, the second clamping plate is moved towards the first clamping plate, so that the second clamping plate pushes the roll, making the roll contact the inner wall of the first clamping plate. After the second clamping plate has finished pushing, the operator can control the lifting device to move the roll towards the frame, so that the roll is tightly fitted with the inner walls of the first and second clamping plates, thereby completing the positioning of the roll and the fixed column.

[0023] 2. This utility model solves the problem of the second clamping plate moving due to the extrusion of the roller by setting a handle, a limiting post, a connecting rod, an insert, and a through hole. When the connecting plate on one side of the second clamping plate presses the lifting plate on the outer wall of the roller against one end of the first clamping plate, the first and second clamping plates complete the adjustment of the extrusion position of the roller. Then, the connecting rod is manually adjusted so that the insert is inserted into the through hole at the end of the connecting post, thereby completing the fixation of the second clamping plate. This ensures that the second clamping plate can always limit the movement direction of the roller during the downward movement of the roller by the lifting device. Attached Figure Description

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The embodiments of this utility model will be described below based on its overall structure.

[0028] Please see Figure 1 — Figure 7 The system includes a fixed plate 1, a sliding plate 103 on one side of the fixed plate 1, fixed posts 104 on the bottom of the sliding plate 103 and on one side of the bottom of the fixed plate 1, a fixed block 107 fixed to one end of the fixed plate 1, a frame 2 connected inside the fixed block 107, a first clamping plate 201 fixed to the top and bottom of one end of the frame 2, a connecting post 204 installed on one side of the frame 2, with both ends of the connecting post 204 penetrating the frame 2, a connecting plate 203 fixed to the top and bottom of the connecting post 204, a second clamping plate 202 installed at one end of the connecting plate 203, a heating coil 101 on one side of the fixed plate 1, a roller 4 placed above the heating coil 101, and grooves 401 formed at both ends of the roller 4, solving the problem that the grooves at both ends of the roller are difficult to fit together. To address the issue of aligning the fixed columns on the heat treatment device, first, flip the frame 2 to the front position of the fixed plate 1, and use the fixing rod 6 to fix the frame 2 in position. Then, move the second clamping plate 202 away from the first clamping plate 201, so that the lifting device can lift the roller 4 and the lifting plate 5 to a position above the heating coil 101. Then, move the second clamping plate 202 towards the first clamping plate 201, so that the second clamping plate 202 pushes the roller 4, making the roller 4 contact the inner wall of the first clamping plate 201. After the second clamping plate 202 has finished pushing, the personnel can control the lifting device to move the roller 4 towards the frame 2, so that the roller 4 is tightly fitted with the inner walls of the first clamping plate 201 and the second clamping plate 202, thereby completing the positioning of the roller 4 and the fixed column 104.

[0029] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 The outer wall of the roll 4 is fitted with a lifting plate 5. A fixed frame plate 501 is installed on the top of the lifting plate 5 and the fixed frame plate 501 is fixedly connected by bolts. A rotating column 502 is fixed at the bottom of the lifting plate 5. A support rod 503 is connected to the end of the rotating column 502. A pin 504 is installed at the end of the support rod 503. When one end of the support rod 503 is fixed to one side of the lifting plate 5 through the pin 504, the support rod 503 supports the top part of the roll 4, and the fixed frame plate 501 limits and fixes one end of the roll 4, so that personnel can lift the roll 4 using a lifting tool.

[0030] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 and Figure 7 The top of the fixing block 107 is provided with an insertion hole 108, the outer wall of the frame 2 is provided with a fixing hole 208, the inside of the insertion hole 108 is provided with a fixing rod 6, and the outer wall of the frame 2 is installed with a handle 207. When the frame 2 is flipped to the front of the fixing plate 1, the person inserts the fixing rod 6 into the fixing block 107. The fixing rod 6 passes through the connection part of the frame 2, thereby fixing the frame 2.

[0031] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 and Figure 2 A baffle 109 is provided on one side of the inside of the fixing block 107. When the frame 2 is flipped so that the wall of the frame 2 contacts the baffle 109, the frame 2 is flipped to the front position of the fixing plate 1.

[0032] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 A slide rail 102 is provided on one side of the fixed plate 1, and a motor 106 is installed on the top of the fixed plate 1. One end of the motor 106 is connected to a lead screw 105, and the lead screw 105 passes through the slide plate 103. Personnel can control the operation of the motor 106 through the control box on the control device. The motor 106 can drive the slide plate 103 to rise and fall vertically through the lead screw 105, so that the fixing post 104 at the bottom of the slide plate 103 is inserted into the groove 401 at one end of the roller 4.

[0033] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 and Figure 6 Both ends of the connecting column 204 are fixed with limit blocks 205. The inner diameter of the first clamping plate 201 and the second clamping plate 202 is equal to the outer diameter of the roller 4. When the personnel pull the connecting column 204 away from the first clamping plate 201, the connecting column 204 cannot be pulled when the limit block 205 contacts the wall of the frame 2.

[0034] For details regarding the above embodiments, please refer to [link / reference]. Figure 6A handle 3 is fitted on the outer wall of the connecting column 204. A limit post 301 is fixed on the outer wall of the handle 3. A connecting rod 302 is connected inside the limit post 301. Insert strips 303 are installed at both ends of the connecting rod 302. Through holes 206 are opened at both ends of the connecting column 204. When the connecting plate 203 on one side of the second clamping plate 202 presses the lifting plate 5 on the outer wall of the roll 4 against one end of the first clamping plate 201, the operator can manually adjust the connecting rod 302 so that the insert strips 303 are inserted into the through holes 206 at the end of the connecting column 204, thereby completing the fixation of the second clamping plate 202.

[0035] For details regarding the above embodiments, please refer to [link / reference]. Figure 6 A support plate 304 is fixed to the outer wall of the connecting post 204, and the support plate 304 is located below the handle 3. When the insert 303 is inserted into the through hole 206, the handle 3 will descend to the top of the support plate 304 due to its own weight, and the support plate 304 will support and limit the handle 3.

[0036] In practical operation, before placing the roller 4 onto the fixing post 104 at the bottom of the fixing plate 1, the frame 2 is first flipped until its outer wall contacts the baffle 109 inside the fixing block 107. The fixing rod 6 is then inserted through the insertion hole 108 at the top of the fixing block 107 into the fixing hole 208 on the frame 2, thus fixing the position of the frame 2. Then, the handle 3 on the outer wall of the connecting post 204 is moved upwards. The handle 3, through the limiting post 301 fixed on its outer wall, drives the connecting rod 302 upwards, thus connecting the connecting rod 302. 2. The inserts 303 at both ends are removed from the through holes 206 on the ends of the connecting column 204. Then, the connecting column 204 is pulled to the outside of the frame 2, causing the second clamping plate 202 to move away from the first clamping plate 201. Subsequently, the position of the roller 4 is simply adjusted by controlling the lifting device, and the roller 4 is brought into contact with the inner wall of the first clamping plate 201. After the roller 4 and the first clamping plate 201 are properly aligned, the connecting column 204 is pushed towards the first clamping plate 201, causing the second clamping plate 202 to move closer to the first clamping plate 201. As the roller 4 approaches the first clamping plate 201, the second clamping plate 202 pushes it towards the first clamping plate 201, making the roller 4 fit tightly against the inner wall of the first clamping plate 201. When the connecting plate 203 on one side of the second clamping plate 202 presses the lifting plate 5 on the outer wall of the roller 4 against one end of the first clamping plate 201, the first clamping plate 201 and the second clamping plate 202 complete the adjustment of the pressing position of the roller 4. Then, the connecting rod 302 is manually adjusted so that the insert 303 is inserted into the through hole 206 at the end of the connecting post 204, thereby completing the fixation of the second clamping plate 202. Then, the personnel control the lifting device to adjust and move the roller 4 to one side of the frame 2, so that the outer wall of the roller 4 fits tightly against the inner wall of the first clamping plate 201 and the second clamping plate 202. Then, the roller 4 is moved downward so that the groove 401 at the bottom of the roller 4 is accurately fitted onto the fixing post 104 at the bottom of the fixing plate 1. Finally, the personnel control the motor 106 through the control box of the device, so that the motor 106 drives the slide plate 103 to rise and fall through the lead screw 105 installed at its end, so that the fixing post 104 on the slide plate 103 is inserted into the groove 401 at the top of the roller 4. Finally, the personnel disassemble the fixed frame plate 501 located on top of the roll 4, and then remove the pin 504 from the lifting plate 5, so that the lifting device can lift and remove the lifting plate 5. After the lifting plate 5 is removed, the personnel remove the fixing rod 108 from the insertion hole 108 inside the fixing block 107, and then flip the frame 2 to provide moving space for the lifting of the heating coil 101.
