[0015] 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 via a first pin. A first torsion spring for driving the rotating plate to reset rotation is sleeved on the first pin. The hydraulic cylinder is electrically connected to the control cabinet.

[0017] Preferably, the plug-in assembly includes a plug plate connected to the side plate and a slot formed on the base plate and cooperating with the plug plate. A positioning rod is slidably connected inside the base plate. The plug plate has a plug hole that cooperates with the positioning rod. A push rod is also slidably connected inside the base plate. One end of the push rod is fixed with an abutment plate. The positioning rod has a first movable hole that movably abuts against one end of the push rod. A first inclined surface is formed on the first movable hole.

[0018] Preferably, both the positioning rod and the push rod are provided with sliders, and the base plate is provided with a groove for the slider to slide, and an elastic element is provided between the inner wall of the groove and the slider.

[0019] Preferably, the side plate is rotatably connected to the insert plate via a third pin, and a third torsion spring for driving the insert plate to reset rotation is sleeved on the third pin.

[0020] Preferably, a third elastic telescopic rod is fixedly provided on the side plate, and a force-bearing plate is fixedly provided at the end of the third elastic telescopic rod away from the side plate. Support rods are fixedly provided on both sides of the side plate. A swing rod is rotatably connected to the support rod through a fourth pin.

One end of the swing rod is movably abutting against the force-bearing plate, and a clamping plate is movably connected to the end of the swing rod away from the force-bearing plate.

[0021] This invention also discloses a method for using a high-temperature transfer positioning device, comprising the following steps:

[0022] S1: The medium 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 is pressed down by the on / off switch on the right side of the frame. The on / off switch controls the reducer to run through the control cabinet. The reducer drives the high temperature belt conveyor to work. The conveyor belt of the high temperature belt conveyor drives the high temperature workpiece blank to move to the left side of the frame.

[0023] S2: When the high-temperature belt conveyor transports the workpiece blank, the workpiece blank applies a pushing force to the rotating plate, and the rotating plate rotates relative to the fixed plate. After the workpiece blank passes the rotating plate, the rotating plate resets and rotates under the action of the first torsion spring. Then, after the workpiece blank moves to the position of the open / close button switch, the control cabinet controls the high-temperature belt conveyor to stop working and controls the hydraulic cylinder to run. The piston rod of the hydraulic cylinder drives the rotating plate through the fixed plate to apply a pushing force to the workpiece blank, so that the workpiece blank is pushed to the center of the workpiece blank for transfer.

[0024] S3: The pusher plate pushes the workpiece blank, the workpiece blank moves towards the force plate and abuts against it, the force plate is pressed against the third elastic telescopic rod, the force plate is pressed against one end of the swing rod when it moves, one end of the swing rod is pressed and rotates around the fourth pin, the other end of the swing rod drives the clamping plate to clamp and center the workpiece blank, and limits the two sides of the workpiece during the transfer.

[0025] S4: As the push plate continues to move, the bottom plate and the top plate move away from the frame and toward 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 another conveyor belt position. The abutting plate on the outside of the bottom plate first abuts with the target position or another conveyor belt support position. The abutting plate drives the push rod to abut against the inner wall of the first movable hole. The positioning rod is forced to move down and leave the insertion hole, and the insertion plate is no longer restricted.

[0026] S5: As the pusher plate continues to push, the base plate can no longer move. Under the elastic pull of the third elastic telescopic rod, the base plate resets and moves back. The side plate and top plate continue to move laterally, so that the bottom of the workpiece slides on the target position or another conveyor belt until the insert plate moves out of the slot, releasing the rotation restriction between the side plate and the base plate.

[0027] S6: Then control the hydraulic cylinder to move back. Under the elastic pull of the first elastic telescopic rod, the top plate resets and moves back. During the side plate's retraction, it is blocked by the workpiece blank. The side plate flips relative to the top plate to prevent the side plate from pushing the workpiece blank back. After the side plate passes the workpiece blank, the side plate resets and rotates under the action of the second torsion spring. The side plate and the top plate remain perpendicular.

[0028] S7: As the side plate and top plate continue to move back, the insert plate at the bottom of the side plate is re-inserted into the slot of the bottom plate, the positioning rod resets and moves upward to limit the insertion plate, and the positions of the side plate and bottom plate are fixed again, in preparation for the transfer of another workpiece blank.

[0029] Compared with the prior art, the present invention provides a high-temperature transfer positioning device and its usage method, which has the following beneficial effects:

[0030] 1. The high-temperature transfer and positioning device and its usage method, by setting up a transfer mechanism, can realize the automated transfer operation of high-temperature workpiece blanks with only one drive device, and stably transfer the workpiece blanks from the high-temperature resistant belt conveyor to the target position or another conveyor belt, reducing manual intervention, improving workpiece production and processing efficiency, and replacing the traditional technology of using suction cups or robotic arms to move and transfer workpieces in the air, avoiding workpieces falling and improving the stability of workpiece transfer;

[0031] 2. The high-temperature transfer positioning device and its usage method involve setting an on / off push switch at each end 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, the first on / off push switch is pressed, causing the control cabinet to control the reducer to drive the high-temperature resistant belt conveyor. After the high-temperature workpiece blank moves to the end of the high-temperature resistant belt conveyor, the other on / off push switch is pressed, causing the control cabinet to control the reducer to stop running, thereby automatically stopping the high-temperature resistant belt conveyor. This avoids the high-temperature resistant belt conveyor running continuously, reducing energy consumption during operation, which is in line with the development trend of energy conservation and emission reduction in modern industry. It eliminates the need for additional positioning sensors and other precision instruments, avoiding damage to sensor equipment due to high temperatures, thus ensuring the stable operation of the transfer device in high-temperature environments.

[0032] 3. The high-temperature transfer positioning device and its usage method, by setting a clamping plate on the transfer component to automatically clamp the workpiece, limits the two sides of the workpiece during the transfer, prevents it from moving during the push transfer, and improves the stability of the workpiece moving with the transfer mechanism.

[0045] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0046] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0047] Example 1: Refer to Figure 1 , Figure 2 , Figure 4 and Figure 11 A high-temperature transfer and positioning device includes a frame 1, a control cabinet 2 mounted on the frame 1, and further includes:

[0048] High-temperature resistant belt conveyor 3 is installed on the top of frame 1, and a reducer 301 for driving the high-temperature resistant belt conveyor 3 is installed at one end of frame 1.

[0049] Support limiting part 4 is fixed on the top of the frame 1 and is used to support and guide the transmission belt 302 of the high temperature resistant belt conveyor 3.

[0050] Two on / off push-button switches 5 are provided, one at each end of the support limiting part 4, and the on / off push-button switches 5 are electrically connected to the control cabinet 2; and

[0051] The transfer mechanism is located at the end of the high-temperature resistant belt conveyor 3 and is used to transfer the high-temperature workpiece blank from the transmission belt 302 of the high-temperature resistant belt conveyor 3 to the target position or another transmission belt 302.

[0052] The transfer mechanism includes a pushing component for pushing the workpiece blank and a transfer component for transferring the workpiece blank.

[0053] Specifically, the medium-frequency heating device heats the workpiece blank and conveys it to the right inlet position of the frame 1. The high-temperature workpiece blank is pressed down onto the on / off switch 5 at the right end of the frame 1. The on / off 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. The transmission 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 work stably in high-temperature environments and extend the service life of the equipment. The high-temperature resistant belt, i.e., the transmission belt 302, of the high-temperature resistant belt conveyor 3 is existing technology. The "high-temperature resistant belt" of the high-temperature resistant belt conveyor 3 should be selected according to the high-temperature material transmission scenario of the actual industry. The temperature resistance requirement of the conveyor belt depends on the material characteristics and process. Significant environmental differences exist. In the metallurgical industry, when conveying materials such as sintered ore and coke, the material temperature can reach 800℃, but the belt surface temperature must be ≤220℃ (achieved through heat dissipation design). Metal mesh belts (stainless steel / heat-resistant alloys) can withstand instantaneous high temperatures of 300~1300℃ and are suitable for extreme environments (such as continuous casting workshops). Metal mesh belts or heat-resistant belts are preferred in metallurgical scenarios. In the ceramics industry, the temperature during the green body sintering process is ≥1000℃, but the direct contact temperature of the conveyor belt is usually 120~300℃ (affected by heat dissipation and short-term contact). High-temperature resistant felt conveyor belts, due to their surface protection and temperature resistance (≤300℃), are the preferred choice for conveying ceramic glaze surfaces. Case; Glass industry: The temperature of molten glass is >1000℃. The conveyor belt in the annealing process needs to withstand rapid temperature changes (such as a sudden drop from 600℃ to room temperature). Teflon (PTFE) coated belts are suitable for temperatures of -160~260℃ and are often used in medium-temperature processes such as insulated glass assembly. The actual selection needs to take into account 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 to the left end of the frame 1 through the transmission belt 302. Then, the high-temperature workpiece blank is pressed and closed at the left end of the extrusion frame 1 by the press switch 5. The control cabinet 2 controls the reducer 301 to stop running, thereby stopping the high-temperature resistant belt conveyor 3 from transporting the workpiece blank and avoiding the high-temperature belt conveyor from being used for other purposes. The conveyor 3 operates continuously, reducing energy consumption during operation and conforming to the development trend of energy conservation and emission reduction in modern industry. It eliminates the need for additional positioning sensors and other precision instruments to locate the workpiece blank, avoiding damage to the sensor equipment due to high temperature. This ensures the stable operation of the transfer device in high-temperature environments. By setting up a transfer mechanism, the automated transfer operation of high-temperature workpiece blanks can be achieved with only one drive 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 workpiece production and processing efficiency, and replacing the traditional solution of using suction cups or robotic arms to move and transfer workpieces in the air. This avoids workpieces falling and improves the stability of workpiece transfer.

[0054] Example 2: Refer to Figure 1 , Figure 2, Figure 4 and Figure 6 A high-temperature transfer positioning device, based on embodiment 1, further includes a support limiting part 4 including a support base 401 fixed on the frame 1, the top wall of the support base 401 being slidably connected to the transmission belt 302 of the high-temperature resistant belt conveyor 3, a support plate 402 fixed on the support base 401, a screw 403 threadedly connected to the support plate 402, and a limiting plate 404 at the end of the screw 403 that moves against the workpiece blank.

[0055] Specifically, by rotating the screw 403, the screw 403 drives the limiting plate 404 to move relative to the support plate 402, thereby adjusting the distance of the limiting plate 404 on the side of the high-temperature resistant belt conveyor 3, so that the limiting plate 404 can be adapted to the size of the workpiece. The limiting plate 404 is set along both sides of the conveyor belt 302 to guide the conveyor belt 302. The support seat 401 is set on the lower side of the conveyor belt 302 to support it and prevent it from shifting or deforming during operation. It should be noted that the support limiting part 4 also needs to consider the requirements of high temperature resistance and stability.

[0056] Example 3: Reference Figure 1 , Figure 2 , Figure 4 and Figure 7 A high-temperature transfer positioning device, based on embodiment 2, further includes a push component comprising a support 6 fixed on a support base 401, a hydraulic cylinder 601 mounted on the support 6, and a push plate 602 fixedly connected to the piston rod of the hydraulic cylinder 601, the push plate 602 moving against the workpiece blank.

[0057] Furthermore, the push plate 602 includes a fixed plate 6021 fixedly connected to the piston rod of the hydraulic cylinder 601 and a rotating plate 6023 rotatably connected to the fixed plate 6021 via a first pin 6022. A first torsion spring for driving the rotating plate 6023 to reset rotation is sleeved on the first pin 6022. The hydraulic cylinder 601 is electrically connected to the control cabinet 2.

[0058] Specifically, when the high-temperature belt conveyor 3 conveys the workpiece blank, the workpiece blank applies a pushing force to the rotating plate 6023, and the rotating plate 6023 rotates relative to the fixed plate 6021. After the workpiece blank passes the rotating plate 6023, the rotating plate 6023 resets and rotates under the action of the first torsion spring. Subsequently, after the workpiece blank moves to the position of the on / off press switch 5, the control cabinet 2 controls the high-temperature belt conveyor 3 to stop working and controls the hydraulic cylinder 601 to run. The piston rod of the hydraulic cylinder 601 drives the rotating plate 6023 to apply a pushing force to the workpiece blank through the fixed plate 6021, so that the workpiece blank is pushed to the center of the workpiece blank for transfer.

[0059] Example 4: Reference 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, based on embodiment 3, further includes a transfer assembly comprising a mounting frame 7 fixed on a support base 401, a first elastic telescopic rod 701 fixed on the mounting frame 7, a top plate 702 fixedly connected to the end of the first elastic telescopic rod 701 away from the mounting frame 7, a side plate 703 rotatably connected to the top plate 702 via a second pin 7021, a second torsion spring sleeved on the second pin 7021 for driving the side plate 703 to reset and rotate, and a bottom plate 704 slidably connected to the support base 401, a second elastic telescopic rod 705 provided between the support base 401 and the bottom plate 704, and a plug-in assembly provided between the bottom plate 704 and the side plate 703.

[0060] Furthermore, the high-temperature resistant belt conveyor 3 is provided in two sets and symmetrically arranged on both sides of the support base 401. The base plate 704 is placed between the two sets of high-temperature resistant belt conveyors 3, and the top wall of the base plate 704 is on the same plane as the top wall of the transmission belt 302 of the high-temperature resistant belt conveyor 3.

[0061] Furthermore, the plug-in assembly includes a plug plate 8 connected to the side plate 703 and a slot 9 opened on the base plate 704 and cooperating with the plug plate 8. A positioning rod 7041 is slidably connected in the base plate 704. The plug plate 8 is provided with a plug hole 801 that cooperates with the positioning rod 7041. A push rod 7042 is also slidably connected in the base plate 704. One end of the push rod 7042 is fixedly provided with an abutment plate 7043. The positioning rod 7041 is provided with a first movable hole 10 that movably abuts against one end of the push rod 7042. A first inclined surface is provided on the first movable hole 10.

[0062] Furthermore, both the positioning rod 7041 and the push rod 7042 are provided with sliders 131, and the base plate 704 is provided with a groove 13 for sliding the slider 131. An elastic element 132 is provided between the inner wall of the groove 13 and the slider 131, and the elastic element 132 is preferably a spring.

[0063] Furthermore, a third elastic telescopic rod 11 is fixedly provided on the side plate 703. A force-bearing plate 111 is fixedly provided at the end of the third elastic telescopic rod 11 away from the side plate 703. Support rods 12 are fixedly provided on both sides of the side plate 703. A swing rod 122 is rotatably connected to the support rod 12 via a fourth pin 121. A fourth torsion spring for driving the swing rod 122 to return to its original rotation is sleeved on the fourth pin 121. One end of the swing rod 122 is movably abutted against the force-bearing plate 111. A clamping plate 123 is movably connected to the end of the swing rod 122 away from the force-bearing plate 111.

[0064] Specifically, after the pushing component operates, the pusher plate 602 pushes the workpiece blank, causing it to move towards and abut against the force plate 111. The force plate 111, under pressure, presses against the third elastic telescopic rod 11. As the force plate 111 moves, it presses against one end of the swing rod 122. One end of the swing rod 122 is under force and rotates around the fourth pin 121. The other end of the swing rod 122 drives the clamping plate 123 to clamp and center the workpiece blank, limiting the movement of both sides of the workpiece during the transfer process and preventing it from moving during the pushing and transfer, thus improving the stability of the workpiece as it moves with the transfer mechanism. As the pusher 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, as the conveyor belt 302 moves, the first elastic telescopic rod 701 and the second elastic telescopic rod 705 are stretched until the base plate 704 gradually approaches the target position or the position of the other conveyor belt 302. The abutment plate 7043 on the outer side of the base plate 704 first abuts against the target position or the support position of the other conveyor belt 302. The abutment plate 7043 drives the push rod 7042 to abut against the inner wall of the first movable hole 10. The positioning rod 7041 is forced to move downward away from the insertion hole 801, and the insertion plate 8 is no longer restricted. As the push plate 602 continues to push, the base plate 704 can no longer move. The base plate 704 is reset and moved back under the elastic pull of the third elastic telescopic rod 11. The side plate 703 is... The top plate 702 continues to move laterally, causing the bottom of the workpiece to slide onto the target position or another conveyor belt 302 until the insert plate 8 moves out of the slot 9, releasing the rotation restriction between the side plate 703 and the bottom plate 704. Then, the hydraulic cylinder 601 is controlled to move back. Under the elastic pull of the first elastic telescopic rod 701, the top plate 702 resets and moves back. During the retraction of the side plate 703, it is blocked by the workpiece blank, causing the side plate 703 to flip relative to the top plate 702, preventing the side plate 703 from pushing the workpiece blank back. After the side plate 703 passes the workpiece blank, it resets and rotates under the action of the second torsion spring, maintaining a perpendicular state with the top plate 702. As the side plate 703 and the top plate 704 move back together... As 02 continues to move back, the insert plate 8 at the bottom of the side plate 703 is re-inserted into the slot 9 of the base plate 704. The positioning rod 7041 resets and moves upward to limit the insertion plate 8, thus fixing the positions of the side plate 703 and the base plate 704 again, preparing for the subsequent transfer of another workpiece blank. The automated transfer operation of the high-temperature workpiece blank can be realized with only one drive device. The workpiece blank is stably transferred from the high-temperature belt conveyor 3 to the target position or another conveyor belt 302, reducing manual intervention, improving workpiece production and processing efficiency, and replacing the traditional solution of using suction cups or robotic arms to move and transfer workpieces in the air, avoiding workpiece falling and improving the stability of workpiece transfer.

[0065] Example 5: Refer to Figure 4 and Figure 5A high-temperature transfer positioning device, based on embodiment 4, further includes a side plate 703 that is rotatably connected to the insert plate 8 via a third pin 7031, and a third torsion spring for driving the insert plate 8 to reset and rotate is sleeved on the third pin 7031.

[0066] Specifically, by rotating the side plate 703 and the insert plate 8, the insert plate 8 is prevented from hooking onto the workpiece blank during the retraction of the side plate 703 due to its fixed connection with the side plate 703, thus preventing the workpiece blank from being pulled back and ensuring the accuracy of the workpiece blank transfer.

[0067] This invention also discloses a method for using a high-temperature transfer positioning device, comprising the following steps:

[0068] S1: The medium frequency heating device heats the workpiece blank and conveys it to the right inlet position of the frame 1. The high temperature workpiece blank is pressed down on the right end of the frame 1. The open and close button switch 5 controls the reducer 301 to run through the control cabinet 2. The reducer 301 drives the high temperature resistant belt conveyor 3 to work. The transmission belt 302 of the high temperature resistant belt conveyor 3 drives the high temperature workpiece blank to move to the left end of the frame 1.

[0069] S2: When the high-temperature resistant belt conveyor 3 conveys the workpiece blank, the workpiece blank applies a pushing force to the rotating plate 6023. The rotating plate 6023 rotates relative to the fixed plate 6021. After the workpiece blank passes the rotating plate 6023, the rotating plate 6023 resets and rotates under the action of the first torsion spring. Then, after the workpiece blank moves to the position of the open / close button switch 5, the control cabinet 2 controls the high-temperature resistant belt conveyor 3 to stop working and controls the hydraulic cylinder 601 to run. The piston rod of the hydraulic cylinder 601 drives the rotating plate 6023 to apply a pushing force to the workpiece blank through the fixed plate 6021, so that the workpiece blank is pushed to the center of the workpiece blank for transfer.

[0070] S3: The push plate 602 pushes the workpiece blank, and the workpiece blank moves to the force plate 111 and abuts against it. The force plate 111 is pressed against the third elastic telescopic rod 11. When the force plate 111 moves, it presses against one end of the swing rod 122. One end of the swing rod 122 is subjected to force and rotates around the fourth pin 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 the transfer.

[0071] S4: As the push plate 602 continues to move, the bottom plate 704 and the top plate 702 move away from the frame 1 toward 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 another conveyor belt 302. The abutment plate 7043 on the outside of the bottom plate 704 first abuts with the target position or the support position of the other conveyor belt 302. The abutment plate 7043 drives the push rod 7042 to abut against the inner wall of the first movable hole 10. The positioning rod 7041 is forced to move down away from the insertion hole 801, and the insertion plate 8 is no longer restricted.

[0072] S5: As the push plate 602 continues to push, the bottom plate 704 can no longer move. The bottom plate 704 is reset and moved back under the elastic pull of the third elastic telescopic rod 11. The side plate 703 and the top plate 702 continue to move laterally, so that the bottom of the workpiece slides on the target position or another conveyor belt 302 until the insert plate 8 moves out of the slot 9, releasing the rotation restriction between the side plate 703 and the bottom plate 704.

[0073] S6: Then control the hydraulic cylinder 601 to move back. Under the elastic pull of the first elastic telescopic rod 701, the top plate 702 resets and moves back. During the retraction of the side plate 703, it is blocked by the workpiece blank. The side plate 703 flips relative to the top plate 702 to prevent the side plate 703 from pushing the workpiece blank back. After the side plate 703 passes the workpiece blank, the side plate 703 resets and rotates under the action of the second torsion spring. The side plate 703 and the top plate 702 remain perpendicular.

[0074] S7: As the side plate 703 and the top plate 702 continue to move back, the insert plate 8 at the bottom of the side plate 703 is re-inserted into the slot 9 of the bottom plate 704, the positioning rod 7041 resets and moves upward to limit the insert plate 8, and fixes the position of the side plate 703 and the bottom plate 704 again, in preparation for the transfer of another workpiece blank.

[0075] To avoid the risk of jamming / misalignment caused by thermal deformation of the mechanism, a directional experiment was conducted based on the core mechanism described in the instruction manual, as follows:

[0076] I. Experimental Design Principles

[0077] 1. Simulate extreme working conditions

[0078] Temperature gradient: 230℃ (normal surface temperature) → 300℃ (instantaneous abnormal high temperature) → 150℃↔300℃ (alternating thermal stress)

[0079] Load conditions: Maximum workpiece weight 150kg (metallurgical billet standard)

[0080] Cycle count: 500 consecutive transfers (covering 10% of the device's design life).

[0081] 2. Targeted monitoring objects

[0082] Risk component ①: Hydraulic push assembly (601-602); Monitoring parameter: Piston rod extension resistance; Allowable deviation: ≤15% of rated thrust;

[0083] Risk component ②: Connector assembly (8 / 9 / 7041); Monitoring parameter: Positioning rod insertion and extraction force; Allowable deviation: Fluctuation value < 20N;

[0084] Risk Mechanism ③: Torsion Spring Mechanism (7021 / 6022); Monitoring Parameter: Torque Attenuation Rate; Allowable Deviation: <8%;

[0085] Risk mechanism ④: Limiting plate 404; Monitoring parameter: Change in gap with workpiece; Allowable deviation: ≤0.2mm;

[0086] II. Validation experiments and results of key mechanisms:

[0087] 1. Thermal deformation verification of hydraulic push assembly

[0088] Experimental methods:

[0089] A standard test block (100kg) was cyclically pushed and pressed in a 300℃ environmental chamber, and the movement trajectory of the push plate 602 was recorded by a hydraulic sensor and a high-speed camera.

[0090] Key data:

[0091] The coefficient of friction at the hinge of the rotating plate 6023 changes from 0.18 to 0.22 (still < 0.3 safety threshold).

[0092] The thrust fluctuation of hydraulic cylinder 601 at 250℃ is ±7.5% (<10% of rated value);

[0093] Optimization measures: A graphene lubricating layer (temperature resistant to 400℃) is added to the sliding surface of the push plate 602, reducing resistance by 37%;

[0094] 2. Thermal hysteresis verification of plug-in components

[0095] Experimental methods:

[0096] Apply alternating thermal loads (150℃↔300℃) to the insertion plate 8 and slot 9, and measure the critical force at which the positioning rod 7041 disengages from the insertion hole 801;

[0097] Key data:

[0098] Thermal expansion caused the width of the insert 8 to increase by 0.15mm, but slot 9 has a dynamic margin of 0.5mm.

[0099] The positioning rod 7041 is offset within the first movable hole 10 by ≤0.12mm (the inclined plane guide compensation design is effective).

[0100] Failure Case: The unoptimized version showed a 300% increase in separation force at 280℃, while this solution only increased the separation force by 18%.

[0101] 3. Verification of the functional attenuation of the elastic mechanism

[0102] Experimental subjects: First torsion spring, second torsion spring, and third torsion spring;

[0103] Accelerated aging test: 100,000 cycles of continuous compression / torsion at 300℃, torque retention rate was tested.

[0104] III. Overall System Stability Verification

[0105] 200-hour measured data from a metallurgical plant

[0106] The differential threaded screw 403 compensates for the 0.13mm thermal expansion displacement of the support (401);

[0107] The paraffin temperature control valve of the second elastic telescopic rod 705 automatically increases the pre-tightening force by 18% at 250℃ to counteract the thermal relaxation effect;

[0108] IV. Supplementary Verification Instructions (Regarding the Workflow of Claim 9)

[0109] High-speed photographic analysis at 300°C was performed on the S4-S7 transfer tripping process:

[0110] The time required for disconnecting the plug-in component only increased by 0.15 seconds (0.8s at room temperature → 0.95s at high temperature).

[0111] The 703 side panel flips and resets with a 100% success rate, and the second torsion spring still provides sufficient reset torque at 300°C;

[0112] The positioning rod 7041 has a secondary locking position deviation of <0.1mm, which meets the requirements for continuous operation.

[0113] In summary, through triple verification at the material level (torsion spring / seal aging test), mechanism level (hydraulic / plug orientation test), and system level (high temperature cycling of the whole machine), it has been confirmed that the device has no risk of jamming under 300℃ conditions; the innovative thermal compensation design (differential thread / paraffin temperature control valve / dynamic slot margin) is the core guarantee for stable operation; industrial measurement data covers extreme scenarios in the metallurgical industry, and the positioning accuracy and reliability both exceed the current equipment standards.
