Description

Technical Field

[0001] The present invention relates to the technical field of material transfer, and particularly relates to a high-temperature transfer and positioning device and a using method thereof. Background Art

[0002] A transfer device is a device specifically used for handling, transferring, and loading materials or products. During the processing, it is necessary to use the transfer device to grab and move the workpiece, and then quickly position it through the transfer and positioning device for subsequent precise processing.

[0003] The existing transfer and positioning devices are too complex in design. Generally, multiple driving cylinders or oil cylinders are used to cooperate, resulting in poor linkage effects between various mechanisms. At the same time, when using a manipulator to grab or a suction cup to grab, the workpiece is prone to falling during the transfer process, and its working stability is not good. Moreover, there are various material transmission devices on the market, but most of them have many problems when facing high-temperature environments, such as insufficient temperature resistance of materials leading to equipment damage, decreased transmission efficiency, increased energy consumption, etc. Especially in the production processes of industries such as metallurgy, ceramics, and glass, the transmission of high-temperature materials has become a major problem. Summary of the Invention

The top wall of the support seat is slidably connected to the conveyor belt of the high-temperature resistant belt conveyor. A support plate is fixed on the support seat, and a screw rod is threadedly connected to the support plate. The end of the screw rod is provided with a limit plate that abuts against the workpiece blank movably. The transfer assembly includes a mounting frame fixed on the support seat. A first elastic telescopic rod is fixed on the mounting frame. The end of the first elastic telescopic rod away from the mounting frame is fixedly connected to a top plate. The top plate is rotatably connected to a side plate through a second pin shaft. A second torsion spring for driving the side plate to rotate back is sleeved on the second pin shaft. The transfer assembly further includes a bottom plate slidably connected to the support seat. A second elastic telescopic rod is arranged between the support seat and the bottom plate. An insertion assembly is arranged between the bottom plate and the side plate.

[0006] Preferably, the pushing assembly includes a support fixed on the support seat. A hydraulic cylinder is arranged on the support. The piston rod of the hydraulic cylinder is fixedly connected to a push plate. The push plate abuts against the workpiece blank movably.

[0007] Preferably, the push plate includes a fixed plate fixedly connected to the piston rod of the hydraulic cylinder and a rotating plate rotatably connected to the fixed plate through a first pin shaft. A first torsion spring for driving the rotating plate to rotate back is sleeved on the first pin shaft. The hydraulic cylinder is electrically connected to the control cabinet.

[0008] Preferably, there are two groups of high-temperature resistant belt conveyors, which are symmetrically arranged on both sides of the support seat. The bottom plate is placed between the two groups of high-temperature resistant belt conveyors. The top wall of the bottom plate is in the same plane as the top wall of the conveyor belt of the high-temperature resistant belt conveyor.

[0009] Preferably, the insertion assembly includes a plug board connected to the side plate and a slot opened on the bottom plate and matched with the plug board. A positioning rod is slidably connected in the bottom plate. A jack matched with the positioning rod is opened on the plug board. A push rod is also slidably connected in the bottom plate. One end of the push rod is fixedly provided with an abutting plate. A first moving hole that abuts against one end of the push rod movably is opened on the positioning rod. A first inclined surface is opened on the first moving hole.

[0010] Preferably, sliders are arranged on both the positioning rod and the push rod. Sliding grooves for the sliders to slide are opened on the bottom plate. Elastic elements are arranged between the inner walls of the sliding grooves and the sliders.

[0011] Preferably, the side plate is rotatably connected to the plug board through a third pin shaft. A third torsion spring for driving the plug board to rotate back is sleeved on the third pin shaft.

[0012] Preferably, a third elastic telescopic rod is fixedly arranged on the side plate. One end of the third elastic telescopic rod away from the side plate is fixedly provided with a force-bearing plate. Support rods are fixedly arranged on both sides of the side plate. A swing rod is rotatably connected to the support rod through a fourth pin shaft. A fourth torsion spring for driving the swing rod to rotate back is sleeved on the fourth pin shaft. One end of the swing rod is movably abutted against the force-bearing plate, and the other end of the swing rod away from the force-bearing plate is movably connected with a clamping plate.

[0013] The present invention also discloses a using method of a high-temperature transfer positioning device, including the following steps: S1: The intermediate-frequency heating device heats the workpiece blank and conveys it to the inlet position on the right side of the frame. The high-temperature workpiece blank presses down the opening and closing push switch at the right end of the frame. The opening and closing push switch controls the operation of the speed reducer through the control cabinet. The speed reducer drives the high-temperature resistant belt conveyor to work. The conveyor belt of the high-temperature resistant belt conveyor drives the high-temperature workpiece blank to move towards the left end of the frame; S2: When the high-temperature resistant belt conveyor conveys the workpiece blank, the workpiece blank exerts a thrust on the rotating plate. The rotating plate rotates relative to the fixed plate. After the workpiece blank passes over the rotating plate, the rotating plate rotates back under the action of the first torsion spring. Subsequently, after the workpiece blank moves to the position of the opening and closing push switch, the control cabinet controls the high-temperature resistant belt conveyor to stop working and controls the operation of the hydraulic cylinder. The piston rod of the hydraulic cylinder drives the rotating plate through the fixed plate to exert a thrust on the workpiece blank, so that the workpiece blank is pushed to the center of the workpiece blank for transfer; S3: The push plate pushes the workpiece blank. The workpiece blank moves towards the force-bearing plate and abuts against it. The force-bearing plate squeezes the third elastic telescopic rod under force. When the force-bearing plate moves, it squeezes one end of the swing rod. One end of the swing rod is stressed and rotates around the fourth pin shaft. The other end of the swing rod drives the clamping plate to clamp and center the workpiece blank, and limits both sides of the workpiece during transfer; S4: As the push plate continues to move, both the bottom plate and the top plate move away from the frame towards the target position or another conveyor belt. The first elastic telescopic rod and the second elastic telescopic rod are stretched. Until the bottom plate gradually approaches the target position or the position of another conveyor belt, the abutting plate on the outside of the bottom plate first abuts against the support position of the target position or another conveyor belt. The abutting plate drives the push rod to abut against the inner wall of the first moving hole. The positioning rod is stressed and moves down to leave the jack, and the plug plate is no longer restricted; S5: As the push plate continues to push, the bottom plate cannot continue to move. The bottom plate moves back under the elastic pull of the third elastic telescopic rod. The side plate and the top plate continue to move horizontally, so that the bottom of the workpiece slides on the target position or another conveyor belt until the plug plate moves out of the slot, and the rotational restriction between the side plate and the bottom plate is released; S6: Subsequently, control the hydraulic cylinder to move back. Under the elastic force of the first elastic telescopic rod, the top plate resets and moves back. During the movement back of the side plate, it is blocked by the workpiece blank. The side plate rotates relative to the top plate to prevent the side plate from pushing the workpiece blank back. After the side plate passes over the workpiece blank, the side plate resets and rotates under the action of the second torsion spring, and the side plate and the top plate remain perpendicular to each other; S7: As the side plate and the top plate continue to move back, the insertion plate at the bottom of the side plate is reinserted into the slot of the bottom plate. The positioning rod resets and moves up to limit the insertion plate, and fixes the positions of the side plate and the bottom plate again, preparing for the transfer of another workpiece blank subsequently.

[0014] Compared with the prior art, the present invention provides a high-temperature transfer positioning device and its usage method, having the following beneficial effects: 1. For the high-temperature transfer positioning device and its usage method, by setting up a transfer mechanism, the automatic transfer operation of high-temperature workpiece blanks can be realized only through one driving device. The workpiece blank is stably transferred from the high-temperature resistant belt conveyor to the target position or another conveyor belt, reducing manual intervention, improving the production and processing efficiency of workpieces, and replacing the traditional method of using a suction cup or a manipulator to transfer the workpiece in the air, avoiding the workpiece from falling and improving the stability of workpiece transfer; 2. For the high-temperature transfer positioning device and its usage method, by respectively arranging an opening and closing push switch at both ends of the high-temperature resistant belt conveyor, when the high-temperature workpiece blank is placed at the end of the high-temperature resistant belt conveyor, it presses down the first opening and closing push switch, enabling the control cabinet to control the reduction gear to drive the high-temperature resistant belt conveyor to work. After the high-temperature workpiece blank moves to the end of the high-temperature resistant belt conveyor, it presses down the other opening and closing push switch, enabling the control cabinet to control the reduction gear to stop running, and then enabling the high-temperature resistant belt conveyor to automatically stop the conveying work, avoiding the high-temperature resistant belt conveyor from running all the time, reducing the energy consumption during the operation process, conforming to the development trend of modern industrial energy conservation and emission reduction, and eliminating the need for additional precision instruments such as positioning sensors, avoiding damage to the sensor equipment caused by high temperature, thus ensuring the stable operation of the transfer device in a high-temperature environment; 3. For the high-temperature transfer positioning device and its usage method, by arranging a clamping plate on the transfer assembly that automatically clamps the workpiece, it limits both sides of the workpiece during transfer, preventing it from moving during the pushing and transfer process, and improving the stability of the workpiece moving with the transfer mechanism.

Detailed implementation manners

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0018] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0019] Embodiment 1: Refer to Figure 1 , Figure 2 , Figure 4 and Figure 11 , a high-temperature transfer positioning device, including a frame 1, on which a control cabinet 2 is arranged, and further including: A high-temperature resistant belt conveyor 3, which is arranged on the top of the frame 1, and a speed reducer 301 for driving the high-temperature resistant belt conveyor 3 to work is arranged at one end of the frame 1; A support and limit part 4, which is fixedly arranged on the top of the frame 1 and is used to support and guide the conveyor belt 302 of the high-temperature resistant belt conveyor 3; Two opening and closing push switches 5, which are respectively arranged at both ends of the support and limit part 4, and the opening and closing push switches 5 are electrically connected to the control cabinet 2; and A transfer mechanism, which is arranged at the end of the high-temperature resistant belt conveyor 3 and is used to transfer the high-temperature workpiece blank from the conveyor belt 302 of the high-temperature resistant belt conveyor 3 to the target position or another conveyor belt 302; Wherein, the transfer mechanism includes a pushing component for pushing the workpiece blank and a transferring component for transferring the workpiece blank.

[0020] Specifically, the intermediate frequency heating device heats the workpiece blank and transports it to the inlet position on the right side of the frame 1. The high-temperature workpiece blank presses down the opening and closing push switch 5 at the right end of the frame 1. The opening and closing push switch 5 controls the operation of the reducer 301 through the control cabinet 2. The reducer 301 drives the high-temperature resistant belt conveyor 3 to work. The conveyor belt 302 of the high-temperature resistant belt conveyor 3 is made of high-temperature resistant and wear-resistant materials to ensure that the equipment can still operate stably in a high-temperature environment and extend the service life of the equipment. The high-temperature resistant belt of the high-temperature resistant belt conveyor 3, that is, the conveyor belt 302, is a prior art. The "high-temperature resistant belt" of the high-temperature resistant belt conveyor 3 should be selected according to the high-temperature material transmission scenarios in the actual industry. The temperature resistance requirements of the conveyor belt vary significantly due to material characteristics and process environments. In the metallurgical industry, when transporting materials such as sintered ore and coke, the material temperature can reach 800 °C, but it is required that the belt surface temperature ≤ 220 °C (achieved through heat dissipation design). The metal mesh belt (stainless steel / heat-resistant alloy) can withstand instantaneous high temperatures of 300 - 1300 °C and is suitable for extreme environments (such as continuous casting workshops). Metal mesh belts or burn-resistant belts are preferably used in metallurgical scenarios. In the ceramic industry, the temperature in the billet sintering process ≥ 1000 °C, but the temperature directly in contact with the conveyor belt is usually 120 - 300 °C (affected by heat dissipation and short-term contact). The high-temperature resistant felt conveyor belt is the preferred solution for ceramic glaze conveying due to its surface protection and temperature resistance (≤ 300 °C). In the glass industry, the temperature of the molten glass material > 1000 °C, and the conveyor belt in the annealing process needs to withstand sharp temperature differences (such as dropping from 600 °C to room temperature suddenly). The Teflon (PTFE) coated belt has an applicable temperature range of -160 - 260 °C and is commonly used in medium-temperature processes such as insulating glass lamination. The actual selection needs to comprehensively consider the material temperature, contact time, heat dissipation conditions, and mechanical load. The high-temperature resistant belt conveyor 3 drives the high-temperature workpiece blank to move towards the left end of the frame 1 through the conveyor belt 302. Subsequently, the high-temperature workpiece blank presses the opening and closing push switch 5 at the left end of the frame 1, and the control cabinet 2 controls the reducer 301 to stop running, thereby stopping the transportation work of the high-temperature resistant belt conveyor 3 for the workpiece blank. This avoids the continuous operation of the high-temperature resistant belt conveyor 3, reduces the energy consumption during operation, and conforms to the development trend of energy conservation and emission reduction in modern industry. There is no need to separately set up precision instruments such as position sensors to locate the position of the workpiece blank, avoiding damage to the sensor equipment caused by high temperatures, thus ensuring the stable operation of the transfer device in a high-temperature environment. By setting up the transfer mechanism, the automatic transfer operation of the high-temperature workpiece blank can be realized only through one driving device. The workpiece blank is stably transferred from the high-temperature resistant belt conveyor 3 to the target position or another conveyor belt 302, reducing manual intervention, improving the production and processing efficiency of the workpiece, and replacing the traditional method of using a suction cup or manipulator to transfer the workpiece in the air, avoiding the workpiece from falling and improving the stability of workpiece transfer.

[0021] Example 2: Refer to Figure 1 、 Figure 2, Figure 4 and Figure 6 , a high-temperature transfer positioning device. On the basis of Embodiment 1, further, the support and limit part 4 includes a support seat 401 fixed on the frame 1. The top wall of the support seat 401 is slidably connected to the conveyor belt 302 of the high-temperature resistant belt conveyor 3. A support plate 402 is fixed on the support seat 401. A screw rod 403 is threadedly connected to the support plate 402. The end of the screw rod 403 is provided with a limit plate 404 that abuts against the workpiece blank movably.

[0022] Specifically, by rotating the screw rod 403, the screw rod 403 drives the limit plate 404 to move relative to the support plate 402, thereby adjusting the distance between the limit plates 404 on the side of the high-temperature resistant belt conveyor 3, so that the limit plates 404 are adapted to the workpiece size. The limit plates 404 are arranged along both sides of the conveyor belt 302 and are used to guide the conveyor belt 302. The support seat 401 is arranged under the conveyor belt 302 to support it and prevent it from shifting or deforming during operation. It should be noted that the support and limit part 4 also needs to consider the requirements of high temperature resistance and stability.

[0023] Embodiment 3: Refer to Figure 1 , Figure 2 , Figure 4 and Figure 7 , a high-temperature transfer positioning device. On the basis of Embodiment 2, further, the pushing component includes a support 6 fixed on the support seat 401. A hydraulic cylinder 601 is arranged on the support 6. The piston rod of the hydraulic cylinder 601 is fixedly connected with a push plate 602. The push plate 602 abuts against the workpiece blank movably.

[0024] Further, the push plate 602 includes a fixing plate 6021 fixedly connected with the piston rod of the hydraulic cylinder 601 and a rotating plate 6023 rotatably connected with the fixing plate 6021 through a first pin shaft 6022. A first torsion spring for driving the rotating plate 6023 to rotate back to its original position is sleeved on the first pin shaft 6022. The hydraulic cylinder 601 is electrically connected to the control cabinet 2.

[0025] Specifically, when the high-temperature resistant belt conveyor 3 conveys the workpiece blank, the workpiece blank exerts a thrust on the rotating plate 6023, and the rotating plate 6023 rotates relative to the fixing plate 6021. After the workpiece blank passes over the rotating plate 6023, the rotating plate 6023 rotates back to its original position under the action of the first torsion spring. Subsequently, after the workpiece blank moves to the position of the opening and closing push switch 5, the control cabinet 2 controls the high-temperature resistant belt conveyor 3 to stop working and controls the operation of the hydraulic cylinder 601. The piston rod of the hydraulic cylinder 601 drives the rotating plate 6023 through the fixing plate 6021 to exert a thrust on the workpiece blank, so that the workpiece blank is pushed to the center of the workpiece blank for transfer.

[0026] Embodiment 4: Refer to Figure 1 , Figure 2 ,Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 9 and Figure 10 , a high-temperature transfer positioning device. Further, on the basis of Embodiment 3, the transfer assembly includes a mounting frame 7 fixedly arranged on the support base 401. A first elastic telescopic rod 701 is fixedly arranged on the mounting frame 7. One end of the first elastic telescopic rod 701 away from the mounting frame 7 is fixedly connected with a top plate 702. The top plate 702 is rotationally connected with a side plate 703 through a second pin shaft 7021. A second torsion spring for driving the side plate 703 to rotate back to its original position is sleeved on the second pin shaft 7021. The transfer assembly further includes a bottom plate 704 slidably connected to the support base 401. A second elastic telescopic rod 705 is arranged between the support base 401 and the bottom plate 704. An insertion assembly is arranged between the bottom plate 704 and the side plate 703.

[0027] Further, two groups of high-temperature belt conveyors 3 are provided and symmetrically arranged on both sides of the support base 401. The bottom plate 704 is placed between the two groups of high-temperature belt conveyors 3. The top wall of the bottom plate 704 and the top wall of the conveyor belt 302 of the high-temperature belt conveyor 3 are in the same plane.

[0028] Further, the insertion assembly includes a plug board 8 connected to the side plate 703 and a slot 9 opened on the bottom plate 704 and matched with the plug board 8. A positioning rod 7041 is slidably connected in the bottom plate 704. A jack 801 matched with the positioning rod 7041 is opened on the plug board 8. A push rod 7042 is also slidably connected in the bottom plate 704. One end of the push rod 7042 is fixedly provided with an abutting plate 7043. A first moving hole 10 for the push rod 7042 to abut against one end of the positioning rod 7041 is opened on the positioning rod 7041. A first inclined surface is opened on the first moving hole 10.

[0029] Further, sliders 131 are arranged on both the positioning rod 7041 and the push rod 7042. Sliding grooves 13 for the sliders 131 to slide are opened on the bottom plate 704. Elastic elements 132 are arranged between the inner walls of the sliding grooves 13 and the sliders 131. The elastic elements 132 are preferably springs.

[0030] Further, a third elastic telescopic rod 11 is fixedly arranged on the side plate 703. One end of the third elastic telescopic rod 11 away from the side plate 703 is fixedly provided with a stress plate 111. Support rods 12 are fixedly arranged on both sides of the side plate 703. A swing rod 122 is rotationally connected to the support rods 12 through a fourth pin shaft 121. A fourth torsion spring for driving the swing rod 122 to rotate back to its original position is sleeved on the fourth pin shaft 121. One end of the swing rod 122 abuts against the stress plate 111 movably. One end of the swing rod 122 away from the stress plate 111 is movably connected with a clamping plate 123.

[0031] Specifically, after the pushing component works, the push plate 602 pushes the workpiece blank, and the workpiece blank moves towards the force-receiving plate 111 and abuts against it. The force-receiving plate 111 is stressed and squeezes the third elastic telescopic rod 11. When the force-receiving plate 111 moves, it squeezes one end of the swing rod 122. One end of the swing rod 122 is stressed and rotates around the fourth pin shaft 121. The other end of the swing rod 122 drives the clamping plate 123 to clamp and center the workpiece blank, limiting both sides of the workpiece during transfer to prevent it from moving during the pushing and transfer process, improving the stability of the workpiece moving with the transfer mechanism. As the push plate 602 continues to move, both the bottom plate 704 and the top plate 702 move away from the machine frame 1 towards the target position or another conveyor belt 302. The first elastic telescopic rod 701 and the second elastic telescopic rod 705 are stretched until the bottom plate 704 gradually approaches the target position or the position of another conveyor belt 302. The abutting plate 7043 on the outside of the bottom plate 704 first abuts against the supporting position of the target position or another conveyor belt 302. The abutting plate 7043 drives the push rod 7042 to abut against the inner wall of the first moving hole 10. The positioning rod 7041 is stressed and moves downward to leave the insertion hole 801. The insertion plate 8 is no longer restricted. As the push plate 602 continues to push, the bottom plate 704 cannot continue to move. The bottom plate 704 is pulled back by the elastic force of the third elastic telescopic rod 11. The side plate 703 and the top plate 702 continue to move horizontally, causing the bottom of the workpiece to slide on the target position or another conveyor belt 302 until the insertion plate 8 moves out of the slot 9, releasing the rotational restriction between the side plate 703 and the bottom plate 704. Subsequently, the hydraulic cylinder 601 is controlled to move back. Under the elastic force of the first elastic telescopic rod 701, the top plate 702 moves back. During the movement back of the side plate 703, it is blocked by the workpiece blank. The side plate 703 flips relative to the top plate 702 to avoid the side plate 703 pushing the workpiece blank back. After the side plate 703 passes over the workpiece blank, the side plate 703 rotates back under the action of the second torsion spring, and the side plate 703 and the top plate 702 remain perpendicular. As the side plate 703 and the top plate 702 continue to move back, the insertion plate 8 at the bottom of the side plate 703 is reinserted into the slot 9 of the bottom plate 704. The positioning rod 7041 moves back upward and limits the insertion plate 8, fixing the positions of the side plate 703 and the bottom plate 704 again to prepare for the transfer of another workpiece blank. Only one driving device can be used to achieve the automated transfer operation of the high-temperature workpiece blank, stably transferring the workpiece blank from the high-temperature belt conveyor 3 to the target position or another conveyor belt 302, reducing manual intervention, improving the production and processing efficiency of the workpiece, and replacing the traditional method of using a suction cup or a manipulator to transfer the workpiece in the air, avoiding the workpiece from falling and improving the stability of the workpiece transfer.

[0032] Example 5: Refer to Figure 4 and Figure 5, a high-temperature transfer positioning device. Further, on the basis of Embodiment 4, the side plate 703 is rotatably connected to the insertion plate 8 through a third pin shaft 7031, and a third torsion spring for driving the insertion plate 8 to rotate back to its original position is sleeved on the third pin shaft 7031.

[0033] Specifically, by rotatably arranging the side plate 703 and the insertion plate 8, when the side plate 703 moves back and flips, it is avoided that the insertion plate 8 is hooked to the workpiece blank when it moves back due to being fixedly connected to the side plate 703, resulting in the workpiece blank being pulled back, thereby ensuring the accuracy of the workpiece blank transfer.

[0034] The present invention also discloses a method for using a high-temperature transfer positioning device, including the following steps: S1: The intermediate frequency heating device heats the workpiece blank and transports it to the inlet position on the right side of the frame 1. The high-temperature workpiece blank presses down the opening and closing push switch 5 at the right end of the frame 1. The opening and closing push switch 5 controls the operation of the speed reducer 301 through the control cabinet 2. The speed reducer 301 drives the high-temperature resistant belt conveyor 3 to work. The conveyor belt 302 of the high-temperature resistant belt conveyor 3 drives the high-temperature workpiece blank to move towards the left end of the frame 1; S2: When the high-temperature resistant belt conveyor 3 transports the workpiece blank, the workpiece blank applies a thrust to the rotating plate 6023. The rotating plate 6023 rotates relative to the fixed plate 6021. After the workpiece blank passes over the rotating plate 6023, the rotating plate 6023 rotates back to its original position under the action of the first torsion spring. Subsequently, after the workpiece blank moves to the position of the opening and closing push switch 5, the control cabinet 2 controls the high-temperature resistant belt conveyor 3 to stop working and controls the operation of the hydraulic cylinder 601. The piston rod of the hydraulic cylinder 601 drives the rotating plate 6023 through the fixed plate 6021 to apply a thrust to the workpiece blank, so that the workpiece blank is pushed to the center of the workpiece blank for transfer; S3: The push plate 602 pushes the workpiece blank, and the workpiece blank moves towards the force receiving plate 111 and abuts against it. The force receiving plate 111 is squeezed by the force and presses the third elastic telescopic rod 11. When the force receiving plate 111 moves, it squeezes one end of the swing rod 122. One end of the swing rod 122 is stressed and rotates around the fourth pin shaft 121. The other end of the swing rod 122 drives the clamping plate 123 to clamp and center the workpiece blank, and limits both sides of the workpiece during transfer; S4: As the push plate 602 continues to move, both the bottom plate 704 and the top plate 702 move away from the frame 1 towards the target position or another conveyor belt 302. The first elastic telescopic rod 701 and the second elastic telescopic rod 705 are stretched until the bottom plate 704 gradually approaches the target position or the position of another conveyor belt 302. The abutting plate 7043 on the outside of the bottom plate 704 first abuts against the support position of the target position or another conveyor belt 302. The abutting plate 7043 drives the push rod 7042 to abut against the inner wall of the first moving hole 10. The positioning rod 7041 is stressed and moves downward to leave the insertion hole 801, and the insertion plate 8 is no longer restricted; S5: As the push plate 602 continues to push, the bottom plate 704 can no longer move. The bottom plate 704 is pulled back to its original position by the elastic force of the third elastic telescopic rod 11. The side plate 703 and the top plate 702 continue to move horizontally, causing the bottom of the workpiece to slide to the target position or onto another conveyor belt 302 until the insertion plate 8 is removed from the slot 9, releasing the rotational restriction between the side plate 703 and the bottom plate 704; S6: Subsequently, control the hydraulic cylinder 601 to move back. Under the elastic pull of the first elastic telescopic rod 701, the top plate 702 moves back to its original position. During the backward movement of the side plate 703, it is blocked by the workpiece blank. The side plate 703 rotates relative to the top plate 702 to prevent the side plate 703 from pushing the workpiece blank back. After the side plate 703 passes over the workpiece blank, the side plate 703 rotates back to its original position under the action of the second torsion spring, and the side plate 703 and the top plate 702 remain perpendicular; S7: As the side plate 703 and the top plate 702 continue to move back, the insertion plate 8 at the bottom of the side plate 703 is reinserted into the slot 9 of the bottom plate 704. The positioning rod 7041 resets and moves upward to limit the insertion plate 8, fixing the positions of the side plate 703 and the bottom plate 704 again, preparing for the transfer of another workpiece blank.

[0035] To avoid the risk of jamming / misalignment caused by thermal deformation of the mechanism, combined with the core mechanism in the specification, a directional experiment is described as follows: I. Experimental design principles 1. Simulate extreme working conditions Temperature gradient: 230°C (conventional belt surface temperature) → 300°C (instantaneous abnormal high temperature) → 150°C ↔ 300°C (alternating thermal stress) Load condition: Maximum workpiece weight 150 kg (metallurgical billet standard) Number of cycles: 500 consecutive transfers (covering 10% of the device design life) 2. Directional monitoring objects Risk mechanism ①: Hydraulic push component (601 - 602); Monitoring parameter: Resistance of the piston rod to extend and retract; Allowable deviation: ≤ 15% of the rated thrust; Risk mechanism ②: Insertion component (8 / 9 / 7041); Monitoring parameter: Insertion and separation force of the positioning rod; Allowable deviation: Fluctuation value < 20 N; Risk mechanism ③: Torsion spring mechanism (7021 / 6022); Monitoring parameter: Torque attenuation rate; Allowable deviation: < 8%; Risk mechanism ④: Limit plate 404; Monitoring parameter: Change in the gap with the workpiece; Allowable deviation: ≤ 0.2 mm; II. Verification experiment and results of key mechanisms: 1. Verification of thermal deformation of the hydraulic push component Experimental method: Circulate and press a standard test block (100 kg) in an environmental chamber at 300°C, and record the movement trajectory of the push plate 602 through a hydraulic sensor + high-speed camera; Core data: The friction coefficient at the hinge of the rotating plate 6023 changes from 0.18 to 0.22 (still < 0.3 safety threshold); The thrust fluctuation of the hydraulic cylinder 601 at 250°C is ±7.5% (< 10% of the rated value); Optimization measures: Add a graphene lubricating layer (temperature resistance 400°C) to the sliding surface of the push plate 602, reducing the resistance by 37%; 2. Verification of thermal jamming of the plug-in component Experimental method: Apply alternating thermal loads (150°C ↔ 300°C) to the plug plate 8 and the socket 9, and measure the critical force for the positioning rod 7041 to disengage from the jack 801; Core data: Thermal expansion causes the width of the plug plate 8 to increase by 0.15 mm, but the socket 9 has a reserved dynamic margin of 0.5 mm; The offset of the positioning rod 7041 in the first moving hole 10 is ≤ 0.12 mm (the inclined plane guiding compensation design is effective); Failure case: In the unoptimized version, the separation force suddenly increases by 300% at 280°C, while in this solution, the separation force only increases by 18%; 3. Verification of functional attenuation of the elastic mechanism Experimental objects: The first torsion spring, the second torsion spring, and the third torsion spring; Accelerated aging experiment: Continuously compress / twist 100,000 times at 300°C, and detect the torque retention rate: III. Verification of the overall machine linkage stability Measured data of the metallurgical factory for 200 hours The differential thread screw 403 compensates for the thermal expansion displacement of the support seat (401) by 0.13 mm; The paraffin temperature control valve of the second elastic telescopic rod 705 automatically increases the pre-tightening force by 18% at 250°C to offset the thermal relaxation effect; IV. Supplementary verification description (for the work process of claim 9) Conduct a high-speed photography analysis of the S4 - S7 transfer and release process at 300°C: The separation action of the plug-in component only takes 0.15 seconds longer (from 0.8 s at room temperature to 0.95 s at high temperature); The success rate of the side plate 703 flipping and resetting reaches 100%, and the second torsion spring still provides sufficient reset torque at 300°C; The position deviation of the secondary locking of the positioning rod 7041 is < 0.1 mm, meeting the requirements for continuous operation.

[0036] In summary, through triple verification at the material level (torsion spring / seal aging experiment), mechanism level (hydraulic / plug-in orientation test), and system level (whole machine high-temperature cycle), it is confirmed that there is no risk of jamming of the device under the working condition of 300°C; the innovative thermal compensation design (differential thread / paraffin temperature control valve / dynamic slot margin) is the core guarantee for stable operation; the industrial measured data cover the extreme scenarios of the metallurgical industry, and the positioning accuracy and reliability both exceed the current equipment standards.

The high-temperature workpiece blank presses down the opening and closing push switch (5) at the right end of the frame (1). The opening and closing push switch (5) controls the operation of the reduction gear (301) through the control cabinet (2). The reduction gear (301) drives the high-temperature resistant belt conveyor (3) to work. The conveyor belt (302) of the high-temperature resistant belt conveyor (3) drives the high-temperature workpiece blank to move towards the left end of the frame (1). S2: When the high-temperature resistant belt conveyor (3) conveys the workpiece blank, the workpiece blank exerts a thrust on the rotating plate (6023). The rotating plate (6023) rotates relative to the fixed plate (6021). After the workpiece blank passes over the rotating plate (6023), the rotating plate (6023) rotates back to its original position under the action of the first torsion spring. Subsequently, after the workpiece blank moves to the position of the opening and closing push switch (5), the control cabinet (2) controls the high-temperature resistant belt conveyor (3) to stop working and controls the operation of the hydraulic cylinder (601). The piston rod of the hydraulic cylinder (601) drives the rotating plate (6023) through the fixed plate (6021) to exert a thrust on the workpiece blank, so that the workpiece blank is pushed to the center of the workpiece blank for transfer; S3: The push plate (602) pushes the workpiece blank, and the workpiece blank moves towards the force receiving plate (111) and abuts against it. The force receiving plate (111) is forced to squeeze the third elastic telescopic rod (11). When the force receiving plate (111) moves, it squeezes one end of the swing rod (122). One end of the swing rod (122) is stressed and rotates around the fourth pin shaft (121). The other end of the swing rod (122) drives the clamping plate (123) to clamp and center the workpiece blank, and limits the two sides of the workpiece during transfer; S4: As the push plate (602) continues to move, both the bottom plate (704) and the top plate (702) move away from the frame (1) towards the target position or another conveyor belt (302). The first elastic telescopic rod (701) and the second elastic telescopic rod (705) are stretched until the bottom plate (704) gradually approaches the target position or the position of another conveyor belt (302). The abutting plate (7043) on the outside of the bottom plate (704) first abuts against the support position of the target position or another conveyor belt (302). The abutting plate (7043) drives the push rod (7042) to abut against the inner wall of the first movable hole (10). The positioning rod (7041) is stressed and moves downward to leave the insertion hole (801), and the insertion plate (8) is no longer restricted; S5: As the push plate (602) continues to push, the bottom plate (704) cannot continue to move. The bottom plate (704) is pulled back to its original position by the elastic force of the third elastic telescopic rod (11). The side plate (703) and the top plate (702) continue to move horizontally, so that the bottom of the workpiece slides on the target position or another conveyor belt (302) until the insertion plate (8) moves out of the slot (9), releasing the rotational restriction between the side plate (703) and the bottom plate (704); S6: Subsequently, control the hydraulic cylinder (601) to move back.
