Technical Field

[0001] This invention relates to the field of hydraulic forming equipment technology, specifically to a high-efficiency hydraulic press for producing heat insulation covers. Background Technology

[0002] The hydraulic press for producing heat insulation covers is a specialized hydraulic forming equipment. It uses a hydraulic system as a power source to drive matching molds to process metal sheets or composite materials through stamping, stretching, molding, and pressure holding curing, making them into heat insulation cover shells required for automobile exhaust pipes, industrial equipment, etc. It features precise and controllable pressure, stable forming, and a high degree of automation, which can ensure the dimensional accuracy, shape consistency, and structural strength of the heat insulation cover.

[0003] However, in existing technologies, material loading is generally done manually. Since the workstations on the turntable rotate as well, manual loading is impossible, thus increasing the efficiency of manual loading. Furthermore, workers need to stack and align the materials to the workstations and perform initial leveling, further contributing to the low production efficiency of the hydraulic press. Moreover, to prevent the aluminum alloy sheets on the outer surface of the heat insulation cover from warping as the turntable rotates, the turntable's rotation speed is typically set low, further limiting the hydraulic press's production efficiency. Summary of the Invention

[0004] (a) Technical problems to be solved: To address the shortcomings of existing technologies, this invention provides a high-efficiency hydraulic press for producing heat insulation covers, which solves the problems mentioned in the background art, such as low efficiency of manual feeding, inability to feed materials when the turntable is rotating, and the tendency of the heat insulation cover sheet to warp, which limits the rotation speed and leads to low production efficiency.

[0005] (II) Technical Solution: To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency hydraulic press for producing heat insulation covers, comprising: Hydraulic pressure plate, used to press down to press together the multi-layer heat insulation material placed at the bottom; The turntable is equipped with several workstations, which are rotated to move different workstations sequentially to the pressing working area of ​​the hydraulic pressure plate; The preset mechanism includes a preset frame that runs vertically through the bottom for placing multi-layer heat insulation cover raw materials, and two opening and closing rotating plates located at the bottom of the preset frame to seal the bottom of the preset frame. The preset mechanism is located on the top of the turntable and is configured together with the hydraulic pressure plate and the turntable to be positioned such that when the turntable rotates to a certain working position and is located in the downward pressing working area of ​​the hydraulic pressure plate, the preset frame is simultaneously located diagonally above another working position of the turntable. When the hydraulic pressure plate is pressed and the turntable rotates, the two opening and closing rotating plates rotate to open the bottom of the preset frame, allowing the multi-layer heat insulation cover raw materials to automatically fall into the working position of the rotating turntable, thus automatically completing the feeding during the rotation of the turntable.

Under the transmission of the transmission gear, it moves in the opposite direction to the driving rack. The upper lever plate is fixedly connected to the bottom of the driven gear; The lower lever plate is fixedly connected to the bottom of the upper lever plate and is spaced apart from the upper lever plate. The lower lever plate is coaxial with the turntable in an arc shape. A guide ramp is formed at the bottom of the lower lever plate on the side near the preset mechanism; The protective frame encloses the meshing parts of the driving rack, the transmission gear, and the driven rack within itself, isolating them from external interference, and the protective frame is slidably connected to the driven rack.

[0008] Preferably, the preset frame includes: The second guide rod is vertically set at the center of the inner side of the preset frame and is fixedly connected to the preset frame extending thereto, providing a sliding guide function; Two second outer rotating shafts are respectively fixed to the outer sides of the bottom two side walls of the preset frame, and are rotatably connected to the opening and closing rotating plates on the same side.

[0009] Preferably, the preset mechanism further includes: The upper pressure member is disposed inside the preset frame, and its top is sleeved on the outside of the second guide rod and slides up and down along the second guide rod; Four abutment rods are fixedly connected to the four corners of the bottom of the upper pressure member, and are all located above the four corners of the inner side of the preset frame and converge inward. An elastic element is disposed between the second guide rod and the upper pressure member, and its two ends are fixedly connected to the second guide rod and the upper pressure member respectively, for providing force to the upper pressure member; Two drive belts are respectively connected to the rotating shafts of the two opening and closing rotating plates; Two meshing gears are both disposed on the back of the preset frame and rotatably connected to the preset frame. The two meshing gears mesh with each other and are connected to the transmission belt on the same side, so that the opening and closing rotating plate and the meshing gears rotate synchronously under the transmission of the transmission belt. A lever is disposed on the opening and closing rotating plate near the drive mechanism, and is located on the side of the opening and closing rotating plate near the drive mechanism and is integrally formed with the opening and closing rotating plate.

[0010] Preferably, the lever is always located between the upper lever plate and the lower lever plate, so as to rotate around the second outer axis under the drive of the upper lever plate and the lower lever plate.

[0011] Preferably, the opening and closing rotating plate includes: A magnetic strip is fixedly connected to one end of the opening and closing rotating plate away from the corresponding second outer rotating shaft on the same side, and is used to generate an attractive force with the magnetic strip on the opposite side to assist the two opening and closing rotating plates in closing horizontally at the bottom of the preset frame.

[0012] Preferably, it further includes an anti-tilting mechanism, the anti-tilting mechanism comprising a plurality of anti-tilting units evenly disposed on the turntable, the anti-tilting unit comprising: A pressing station, located at the bottom of the turntable, is used to provide a place for stacked multi-layer heat insulation cover raw materials; An arc-shaped groove is formed on the turntable and its top is connected to the outside. The arc-shaped groove is located in front of the pressing station in the direction of rotation. The first outer rotating shaft is fixedly connected to the top of the turntable and is located on the top side of the arc groove near the pressing station; A rotating pressure plate is rotatably connected to the first outer rotating shaft, with one end located outside the arc-shaped groove and the other end located inside the arc-shaped groove; A reset torsion spring is disposed on the outside of the rotating shaft that is rotatably connected to the first outer rotating shaft and the rotating pressure plate, and is used to provide a reset force for the rotating pressure plate.

[0013] Preferably, it further includes: The fastener is fixedly connected to the fixed top plate and located above the center of the turntable. It is also fixedly connected to the protective frame and the preset frame to fix the positions of the protective frame and the preset frame.

[0014] Preferably, the rotating pressure plate is configured such that, as it moves toward the hydraulic pressure plate along with the turntable, the side of the plate closest to the hydraulic pressure plate contacts the guide slope, and rotates away from the hydraulic pressure plate under the guidance of the guide slope, so that one end of the rotating pressure plate located outside the arc groove presses against the end of the stacked multi-layer heat insulation cover material facing the rotation direction of the turntable, thus preventing this end from tilting up.

[0015] (III) Beneficial Effects: The high-efficiency hydraulic press for producing heat insulation covers provided by this invention has the following beneficial effects: 1. This high-efficiency hydraulic press for producing heat insulation covers uses a multi-station turntable and an automatic feeding preset mechanism to work together to replace manual feeding with automatic material dropping during the turntable rotation. The multi-layer heat insulation cover raw materials in the preset frame can fall accurately into the corresponding station when the turntable rotates. It is only necessary to manually place the stacked heat insulation cover raw materials in the preset frame during the hydraulic pressing process, without affecting the overall workflow. There is no need for manual alignment, stacking and pre-pressing, thus solving the problem of manual feeding when the turntable of the traditional hydraulic press is rotating. It significantly shortens the feeding waiting time, improves the continuous operation capability of the equipment, and greatly improves the production efficiency of heat insulation cover pressing.

[0016] 2. This high-efficiency hydraulic press for producing heat insulation covers forms a pure mechanical linkage between the movement of the hydraulic pressure plate, the drive mechanism, and the preset mechanism. The up-and-down displacement of the hydraulic pressure plate serves as the power source, and the power is transmitted through the active rack, transmission gear, and driven rack to directly control the opening and closing of the bottom rotating plate of the preset frame. There is no need to add additional drive components such as motors and cylinders, which simplifies the overall structure, reduces the failure rate and energy consumption, and at the same time makes the pressing action and the feeding action highly synchronized and precise in timing, ensuring a stable and reliable production process.

[0017] 3. This high-efficiency hydraulic press for producing heat insulation covers, through the cooperation of an anti-warping mechanism, a guide ramp, and a rotating pressure plate, automatically presses the end of the heat insulation cover raw material facing the direction of rotation when the turntable starts rotating. This prevents the surface aluminum alloy sheet from warping or shifting due to centrifugal force and airflow, thereby improving product forming quality and pass rate, and safely increasing the turntable rotation speed. This breaks through the speed limit set by the anti-warping mechanism in existing equipment, further improving the overall production efficiency of the hydraulic press. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 refer to Figures 1 to 8 A high-efficiency hydraulic press for producing heat shields according to a preferred embodiment of the present invention will be described in detail below: The hydraulic pressure plate 11 is used to press down to press the multi-layer heat insulation cover material placed at the bottom, so that the multi-layer heat insulation cover material is tightly bonded and formed.

[0022] The turntable 21 is equipped with several workstations, which are rotated to move different workstations sequentially to the pressing working area of ​​the hydraulic pressure plate 11. The multiple and continuous rotations of the turntable 21 replace the intermittent operation of a single workstation, improving processing efficiency. The workstations on the turntable 21 are moved in an orderly and cyclical manner to the working area of ​​the hydraulic pressure plate 11. With the help of the preset mechanism, drive mechanism and anti-tilting mechanism, the loading, pressing and unloading are carried out simultaneously, realizing continuous processing.

[0023] The preset mechanism includes a preset frame 40 that runs vertically through the bottom for placing multi-layer heat insulation cover material, and two opening and closing rotating plates 43 located at the bottom of the preset frame 40 to seal the bottom of the preset frame 40. The preset mechanism is located on the top of the turntable 21, and together with the hydraulic pressure plate 11 and the turntable 21, it is configured such that when the turntable 21 rotates to a certain position and is located in the downward pressing working area of ​​the hydraulic pressure plate 11, the preset frame 40 is simultaneously located diagonally above another position of the turntable 21. When the hydraulic pressure plate 11 is pressed and the turntable 21 rotates, the two opening and closing rotating plates 43 rotate to open the bottom of the preset frame 40, allowing the multi-layer heat insulation cover material to automatically fall into the working position of the rotating turntable 21 (the multi-layer heat insulation cover material in the preset frame 40 is placed manually). The material is loaded while the turntable 21 is rotating, eliminating the manual operation of aligning and pre-pressing the multi-layer heat insulation cover material, and avoiding the problem of not being able to load the material when the turntable 21 is rotating, which makes it difficult to improve work efficiency. The material loading is completed automatically while the turntable 21 is rotating.

[0024] Also includes: The base 10 is used to support its own top structure and provide stable support.

[0025] Several first guide rods 12 are vertically arranged, with one end fixedly connected to the top of the base 10, and all pass through the hydraulic pressure plate 11. They are used to guide the hydraulic pressure plate 11 to move vertically, ensuring that the hydraulic pressure plate 11 only moves vertically up and down, preventing deviation or tilting, and ensuring that the pressing pressure is evenly applied to the multi-layer heat insulation cover material, thereby improving the pressing quality.

[0026] The fixed top plate 13 is fixedly connected to one end of several first guide rods 12 away from the base 10, providing a mounting carrier for the hydraulic rod 14 and several first guide rods 12. Together with the base 10, the first guide rods 12 become a fixed structure to ensure the stability of the movement of the hydraulic pressure plate 11.

[0027] The hydraulic rod 14 is fixedly connected to the fixed top plate 13 on the side near the base 10. Its output end is located at its bottom and fixedly connected to the hydraulic pressure plate 11. It is used to drive the hydraulic pressure plate 11 to move along several hydraulic pressure plates 11, providing stable downward pressure to the hydraulic pressure plate 11. The power of the hydraulic rod 14 is adjustable, so as to adapt to the pressing requirements of heat insulation covers of different thicknesses and layers.

[0028] The control box 15 is fixedly connected to the top of the fixed top plate 13 and electrically connected to the hydraulic rod 14 to control the start and stop, pressure, and stroke distance of the hydraulic rod 14, so as to ensure the accuracy and stability of the pressing parameters.

[0029] The drive motor 20 is located at the bottom of the turntable 21 and its output end is fixedly connected to the turntable 21. It is used to drive the turntable 21 to work and control the rotation speed, angle and pause time of the turntable 21 during the process, so that different pressing stations 211 can accurately stop at the bottom of the hydraulic pressure plate 11 and the preset frame 40. It can also work in conjunction with the pressing and feeding rhythm to improve the pressing efficiency.

[0030] Also includes: The drive mechanism, located between the hydraulic pressure plate 11 and the preset mechanism, includes: The active rack 30 is fixedly connected to the hydraulic pressure plate 11 and moves synchronously with the hydraulic pressure plate 11, converting the vertical linear motion of the hydraulic pressure plate 11 into the power source of the entire drive mechanism, thus eliminating the need for additional power components and achieving mechanical linkage between the pressing action and the unloading action.

[0031] The transmission gear 31 meshes with the drive rack 30 and rotates under the movement of the drive rack 30, transmitting the power of the drive rack 30 to the driven rack 32, causing the driven rack 32 to move vertically in the opposite direction to the drive rack 30.

[0032] The driven rack 32 is located on the side of the transmission gear 31 away from the driving rack 30 and meshes with the transmission gear 31. Under the transmission of the transmission gear 31, it moves in the opposite direction to the driving rack 30, thereby driving the upper deflector plate 33 and the lower deflector plate 34 connected at the bottom to move synchronously.

[0033] The upper lever plate 33 is fixedly connected to the bottom of the driven gear 32; The lower deflector plate 34 is fixedly connected to the bottom of the upper deflector plate 33 and has a gap between them. The lower deflector plate 34 is coaxial with the turntable 21 in an arc shape, so as to adapt to the movement trajectory of the rotating pressure plate 23 that follows the rotation of the turntable 21. This ensures that when the rotating pressure plate 23 contacts the lower deflector plate 34 and the guide slope 341, it is stably guided by the lower deflector plate 34 and the guide slope 341 to rotate towards the multi-layer heat insulation material, thereby pressing the windward side of the multi-layer heat insulation material together and preventing the thin aluminum alloy sheet on the outer surface of the multi-layer heat insulation material from lifting when the turntable 21 rotates.

[0034] The guide slope 341 is located at the bottom of the lower plate 34 near the preset mechanism, providing an inclined guiding function for the rotating pressure plate 23. The rotation angle of the rotating pressure plate 23 is controlled by the bottom of the lower plate 34, thereby achieving the pressing of the windward side of the multi-layer heat insulation material.

[0035] The protective frame 35 encloses the meshing parts of the driving rack 30, transmission gear 31 and driven rack 32 inside itself, isolating them from external interference and preventing external dust and debris from entering the protective frame 35 and causing jamming and wear on the meshing parts of the driving rack 30, transmission gear 31 and driven rack 32. The protective frame 35 is slidably connected to the driven rack 32.

[0036] Preset box 40 includes: The second guide rod 401 is vertically set at the center of the inner side of the preset frame 40 and is fixedly connected to the preset frame 40 extending thereto. It provides a sliding guide function and provides a sliding guide function for the upper pressing member 41, ensuring that the upper pressing member 41 presses down smoothly, pressing the four corners of the multi-layer heat insulation cover and the multi-layer heat insulation cover material to move downward synchronously (under the elastic force when the elastic member 42 extends) and pressing the multi-layer heat insulation cover material onto the corresponding pressing station 211, thereby completing the feeding.

[0037] Two second outer rotating shafts 402 are respectively fixed to the outer sides of the bottom two side walls of the preset frame 40, and are rotatably connected to the corresponding opening and closing rotating plates 43 on the same side. These shafts serve as the rotation axes of the opening and closing rotating plates 43, ensuring the rotation of the plates around these axes while also increasing the rotation angle of the plates, so that when the plates are closed, they are perpendicular to the side walls of the preset frame 40 (e.g., ...). Figure 8 As shown, when opened, it can form an obtuse angle with the side wall on the same side as the preset frame 40, which makes it easy for the multiple heat insulation material originally placed in the preset frame 40 to fall vertically downward into the corresponding pressing station 211, completing automatic and precise feeding.

[0038] The preset mechanism also includes: The upper pressure member 41 is located inside the preset frame 40, and its top is sleeved on the outside of the second guide rod 401 and slides up and down along the second guide rod 401. Under the elastic force of the elastic member 42, the upper pressure member 41 is always subjected to a downward force, and the force is applied downward to the stacked multi-layer heat insulation cover placed in the preset frame 40 through the four abutment rods 411. The specific positions of the upper pressure member 41, abutment rods 411 and opening and closing rotating plate 43 are as follows: Figure 8 As shown.

[0039] Four abutment rods 411 are fixedly connected to the four corners of the bottom of the upper pressing component 41, and are all located above the four corners of the inner side of the preset frame 40 and converge inwards. The four abutment rods 411 make even contact with the multi-layer heat insulation material stacked at the bottom, keeping the multi-layer material neat within the preset frame 40, preventing the material from loosening before falling, and continuously pressing the multi-layer heat insulation material stacked at the bottom downwards until it fits against the opening and closing rotating plates 43 as the angle of the two opening and closing rotating plates 43 changes, thus ensuring the stability of the two opening and closing rotating plates 43 during rotation. After the rotation angle of the two opening and closing rotating plates 43 is greater than 90°, the multi-layer heat insulation material stacked at the bottom is immediately moved downwards, thus accurately falling into the preset pressing station 211, ensuring accuracy throughout the process. The convergence of the four abutment rods 411 inwards facilitates the subsequent return of the two opening and closing rotating plates 43 to their original position. Figure 8 In the state shown, the retracted opening and closing rotating plate 43 applies an upward force to the entire upper pressure member 41 along with the inwardly retracting abutment rod 411, thereby driving the entire upper pressure member 41 to move upward and return to the state shown. Figure 8 The initial position shown facilitates the workers' manual placement of the stacked multi-layer heat insulation cover material between the support rod 411 and the opening and closing rotating plate 43 for the next operation.

[0040] The elastic element 42 is disposed between the second guide rod 401 and the upper pressure element 41, and its two ends are fixedly connected to the second guide rod 401 and the upper pressure element 41 respectively, and is used to continuously provide a downward force to the upper pressure element 41.

[0041] Two drive belts 44 are respectively connected to the rotating shafts of the two opening and closing rotating plates 43. Specifically, the rotational power of the opening and closing rotating plate 43 equipped with the lever 46 is transmitted to the meshing gear 45 on the same side. This meshing gear 45 transmits the power to the meshing gear 45 on the other side through meshing connection. This meshing gear 45 then transmits the rotational power to the opening and closing rotating plate 43 on the same side, thereby realizing that both opening and closing rotating plates 43 open and close simultaneously. The drive belts 44 can be directly selected from existing technologies such as synchronous belts. Synchronous belts can ensure the accuracy of power transmission through their internal teeth, ensuring that the two opening and closing rotating plates 43 open and close synchronously.

[0042] Two meshing gears 45 are both set on the back of the preset frame 40 and rotatably connected to the preset frame 40. The two meshing gears 45 mesh with each other to ensure the transmission between the two meshing gears 45, and are also connected to the corresponding transmission belt 44 on the same side so that the opening and closing rotating plate 43 and the meshing gears 45 rotate synchronously under the transmission of the transmission belt 44. A lever 46 is disposed on the opening / closing rotating plate 43 near the drive mechanism, and is integrally formed with the opening / closing rotating plate 43 to ensure the structural strength of the lever 46 and the opening / closing rotating plate 43. Through contact with the upper lever 33 above and the lower lever 34 below, the lever 46 is driven to rotate, thereby driving the opening / closing rotating plate 43 to rotate through its integral formation with the plate, thus controlling the opening and closing of the two opening / closing rotating plates 43.

[0043] The lever 46 is always positioned between the upper lever plate 33 and the lower lever plate 34, so that it rotates around the second outer rotating shaft 402 under the drive of the upper lever plate 33 and the lower lever plate 34. This causes the drive mechanism to drive the lever 46 to rotate around the second outer rotating shaft 402, thereby driving the two opening and closing rotating plates 43 to rotate simultaneously, and thus driving the entire preset mechanism to work.

[0044] The opening and closing rotating plate 43 includes: Magnetic strip 431 is fixedly connected to one end of the opening and closing rotating plate 43 away from the corresponding second outer rotating shaft 402 on the same side. It is used to generate an attractive force with the magnetic strip 431 on the opposite side to assist the two opening and closing rotating plates 43 in closing horizontally at the bottom of the preset frame 40, ensuring that the two opening and closing rotating plates 43 are in a position as shown in the image. Figures 6 to 8 The closure shown is tight.

[0045] The following is the complete working process and working principle of the above embodiments: The drive motor 20 drives the turntable 21 to rotate, causing each pressing station 211 to move sequentially to the bottom and pressing area of ​​the preset frame 40 and the hydraulic pressure plate 11. The multi-layer heat insulation cover material is manually placed into the preset frame 40, supported by the two opening and closing rotating plates 43 at the bottom of the preset frame 40. Under the action of the elastic member 42, the upper pressing member 41 presses and positions the material through the abutment rod 411 to prevent it from deviating within the preset frame 40. When the hydraulic rod 14 drives the hydraulic pressure plate 11 to press downwards, the active gear 30 fixed to it moves downwards synchronously. Through the transmission gear 31, it drives the driven gear 32 to move upwards, causing the upper deflector plate 33 and the lower deflector plate 34 to rise synchronously. This causes the deflector block 46 located between them to rotate. Then, through the transmission belt 44 and another meshing gear 45, the two opening and closing rotating plates 43 are driven to open outwards synchronously around the second outer rotating shaft 402. The multi-layer heat insulation cover material in the preset frame 40 falls into the lower turntable 21 station under the force of gravity and the thrust of the abutment rod 411 (the error caused when falling to the station is within the allowable range), completing the synchronous rotational feeding. After pressing, the hydraulic pressure plate 11 moves upwards, the active gear 30 moves upwards and drives the driven gear 32 to move downwards, the upper deflector plate 33 and the lower deflector plate 34 descend, the deflector block 46 reverses, and drives the opening and closing rotating plates 43 to close and reset. The upper pressing component 41 then moves upwards and resets, waiting for the next round of feeding.

[0046] Example 2 refer to Figures 1 to 5 and Figure 9 It also includes an anti-tilting mechanism, which comprises a plurality of anti-tilting units evenly distributed on the turntable 21. The anti-tilting unit includes: The pressing station 211 is located at the bottom of the turntable 21 and is used to provide a place for stacked multi-layer heat insulation cover raw materials. Its specific structure is specially designed to adapt to the shape and pressing requirements of the stacked multi-layer heat insulation cover.

[0047] The arc-shaped groove 212 is opened on the turntable 21 and its top is connected to the outside. The arc-shaped groove 212 is located in front of the rotation direction of the pressing station 211, ensuring that the subsequent rotating pressure plate 23 can effectively contact the stacked multi-layer heat insulation cover material when it rotates in the direction of the pressing station 211, thereby achieving the technical effect of pressing down the forward side of the stacked multi-layer heat insulation cover material and preventing it from tilting up due to the rotation of the turntable 21.

[0048] The first outer rotating shaft 22 is fixedly connected to the top of the turntable 21 and is located on the top side of the arc groove 212 near the pressing station 211. This ensures that when the rotating pressing plate 23 rotates around the connecting shaft with the first outer rotating shaft 22, the end of the rotating pressing plate 23 near the pressing station 211 is always located above the turntable 21 to accommodate the height difference between the stacked multi-layer heat insulation material and the top of the turntable 21. This prevents the multi-layer heat insulation material from being pressed too deeply due to the excessive rotation angle of the rotating pressing plate 23, which would cause deformation of the stacked multi-layer heat insulation material and affect the quality of the finished product produced by subsequent pressing.

[0049] The rotating pressure plate 23 is rotatably connected to the first outer rotating shaft 22, with one end located outside the arc groove 212 and the other end located inside the arc groove 212. When the rotating pressure plate 23 moves forward with the turntable 21, the end of the rotating pressure plate 23 located outside the arc groove 212 will contact the fixed guide slope 341, and then be driven by the guide slope 341 to rotate towards the pressing station 211 until the end of the rotating pressure plate 23 close to the pressing station 211 directly contacts and presses the multi-layer heat insulation cover raw material placed on the pressing station 211, preventing the aluminum alloy sheet at the top from lifting due to movement, thereby avoiding the situation where the rotation speed of the turntable 21 is too low due to the easy lifting of the aluminum alloy sheet, resulting in difficulty in improving production efficiency and low finished product quality qualification rate.

[0050] The reset torsion spring 24 is located on the outside of the rotating shaft that rotatably connects the first outer rotating shaft 22 and the rotating pressure plate 23, and is used to provide a reset force for the rotating pressure plate 23, i.e. Figure 9 The initial position shown ensures that the next pressing operation of the stacked multi-layer heat insulation material is not affected, thus achieving automatic circulation.

[0051] Also includes: The fixing component 50 is fixedly connected to the fixed top plate 13 and located above the center of the turntable 21. It is also fixedly connected to the protective frame 35 and the preset frame 40 to fix the position of the protective frame 35 and the preset frame 40, ensuring the relative position of the drive mechanism, the preset mechanism, the turntable 21, and the anti-tilting mechanism, and ensuring that their linkage actions are performed accurately.

[0052] The rotating pressure plate 23 is configured such that when it moves with the turntable 21 toward the hydraulic pressure plate 11, the side of the rotating pressure plate 23 that is close to the hydraulic pressure plate 11 contacts the guide slope 341, and rotates away from the hydraulic pressure plate 11 under the guidance of the guide slope 341, so that one end of the rotating pressure plate 23 located outside the arc groove 212 presses against the end of the stacked multi-layer heat insulation cover material facing the rotation direction of the turntable 21, preventing this end from tilting up.

[0053] The following is the complete working process and working principle of the above embodiments: The drive motor 20 drives the turntable 21 to rotate at a uniform speed. Each pressing station 211 moves sequentially to the working position. The preset mechanism completes the automatic feeding of the heat insulation cover material, and the multi-layer heat insulation cover material is transported into the pressing station 211. The rotating pressure plate 23, which rotates together with the turntable 21, contacts the guide slope 341 of the lower plate 34 on the side near the hydraulic pressure plate 11. Under the guidance of the slope, it rotates around the first outer rotating shaft 22 toward the pressing station 211. When the multi-layer heat insulation cover material begins to move, it firmly presses the end of the heat insulation cover material facing the rotation direction of the turntable 21, thereby preventing the surface aluminum alloy sheet from warping during high-speed rotation. After the rotating pressure plate 23 rotates past the guide slope 341 and the entire lower plate 34 with the turntable 21, the rotating pressure plate 23 no longer contacts the lower plate 34. At this time, the multi-layer heat insulation material moves to the bottom of the hydraulic pressure plate 11 under the drive of the turntable 21. The reset torsion spring 24 also drives the rotating pressure plate 23 to rotate and reset, located outside the working area of ​​the hydraulic pressure plate 11, preparing for the anti-warping pressing of the next pressing station 211.
