Description

Technical Field

[0001] This application relates to the field of automotive underbody protection plate manufacturing equipment, and in particular to an automotive underbody protection plate cooling and shaping device. Background Technology

[0002] The cooling and shaping device for automotive underbody panels is an indispensable part of the automobile manufacturing process, primarily used to ensure the dimensional stability and surface quality of the vehicle body's underside after high-temperature molding. With the rapid development of the automotive industry, higher demands are being placed on the production efficiency and product quality of automotive underbody panels. Efficient cooling and shaping technology can not only shorten the production cycle but also significantly enhance the product's market competitiveness.

[0003] Currently, common methods for cooling and shaping automotive underbody panels mainly include natural cooling and air cooling. Natural cooling is the simplest method, requiring only the shaped underbody panel to be placed in a well-ventilated environment to gradually cool down. While this method is inexpensive, the cooling time is long, making it difficult to meet the time-sensitive requirements of large-scale production. Another commonly used method is air cooling, which uses airflow generated by a fan to accelerate heat dissipation.

[0004] Existing cooling and shaping devices have significant shortcomings in practical applications, especially during batch processing, exhibiting low cooling efficiency and unstable cooling effects. Specifically, the cooling process easily leads to deformation of the vehicle's underbody protection plate, a problem particularly pronounced during continuous multi-batch production. These issues not only prolong the production cycle but also reduce product yield, severely restricting the company's production efficiency and economic benefits. Therefore, developing a new technological solution that effectively addresses these problems is of paramount importance. Summary of the Invention

[0005] To improve cooling efficiency and production efficiency, this application provides a cooling and shaping device for automotive underbody protection plates.

[0006] This application provides a cooling and shaping device for automotive underbody protection plates, which adopts the following technical solution: A cooling and shaping device for automotive underbody protection plates includes a cooling box and a shaping template. A first conveyor belt for conveying the shaping template into the cooling box is provided on one side of the cooling box. Two symmetrically arranged discharge gates are rotatably connected to the upper end of the cooling box along a conveying direction perpendicular to the first conveyor belt. A feed gate is hinged to the side wall of the cooling box near the first conveyor belt. Several cooling devices are evenly arranged horizontally and vertically on two inner walls of the cooling box parallel to the conveying direction of the first conveyor belt. Four second conveyor belts, arranged symmetrically in pairs, are provided inside the cooling box for lifting the shaping template. Two troughs are provided on each side of the cooling box parallel to the conveying direction of the first conveyor belt, and the four second conveyor belts are located within their respective troughs. The side of each second conveyor belt near the shaping template is flush with the side wall of the cooling box, and several lifting plates are evenly arranged along the circumference of each second conveyor belt.

[0007] By adopting the above technical solution, placing the car underbody protection plate on a matching shaping template can avoid material deformation during transportation and cooling. The first conveyor belt transports the car underbody protection plate placed on the shaping template into the cooling box for cooling, improving the automation level of the equipment, reducing manual intervention, and increasing production efficiency. The lifting plates on the four second conveyor belts jointly abut against the four corners of the lower end face of the shaping template, driving multiple shaping templates to rise simultaneously in the cooling box, increasing the cooling box's capacity for batch cooling of car underbody protection plates. The uniformly distributed cooling devices inside the cooling box ensure the uniformity and efficiency of cooling during the rising of multiple shaping templates. The setting of the discharge door and the inlet door increases the sealing of the cooling box, reduces heat exchange with the outside, reduces energy consumption, and improves cooling efficiency.

[0008] Optionally, the cooling box is fixed with two horizontally arranged fixed rods, and the fixed rods are rotatably connected to several rotating wheels. The several rotating wheels are evenly arranged along the conveying direction of the first conveyor belt, and the axis of the rotating wheels extends perpendicular to the conveying direction of the first conveyor belt. The outer wall of the rotating wheel abuts against the lower end face of the shaping template. The rotating wheel near the feed gate is coaxially fixed with a conveying motor, and the conveying motor is fixedly connected to the fixed rods.

[0009] By adopting the above technical solution, when the first conveyor belt conveys the shaping template into the cooling box, since the first conveyor belt is located outside the cooling box, part of the shaping template cannot be conveyed into the cooling box by the first conveyor belt. The conveyor motor drives the rotating wheel to rotate and completely convey the shaping template on the first conveyor belt into the cooling box, thereby improving the stability and smoothness of the shaping template conveying.

[0010] Optionally, a first conveyor plate that moves perpendicular to the conveying direction of the first conveyor belt is provided above the cooling box. A first lifting frame that slides vertically and is connected to the first conveyor plate is provided between the first conveyor plate and the cooling box. Two first guide rods are fixedly provided on the upper end of the first lifting rod. The upper end of the first guide rod extends upward through the first conveyor plate. A first lifting cylinder is fixedly provided on the upper end of the first conveyor plate. The telescopic end of the first lifting cylinder passes through the first conveyor plate and is fixedly connected to the upper end of the first lifting frame. Several first suction cups for adsorbing the shaping template are provided on the lower end of the first lifting frame. A first bracket is provided on the outside of the cooling box. A first screw with an axis perpendicular to the conveying direction of the first conveyor belt is rotatably connected to the first bracket. The first conveyor plate is threadedly connected to the first screw. A first motor for driving the first screw to rotate is fixedly connected to the first bracket. A first slide rod parallel to the axis of the first screw is fixedly connected to the first bracket. The first conveyor plate is slidably connected to the first slide rod. A third conveyor belt that conveys the shaping template to the end of the first conveyor belt away from the cooling box is provided on one side of the cooling box. The third conveyor belt is located between the two ends of the first screw.

[0011] By adopting the above technical solution, the first conveyor plate can move in a direction perpendicular to the first conveyor belt. In conjunction with the first lifting cylinder and the first suction cup, it can quickly and accurately remove the shaped template containing the cooled car underbody protection plate from the cooling box and place it on the third conveyor belt. At the same time, the third conveyor belt can transport the shaped template to the designated position. The whole process is highly automated and improves production efficiency. The sliding connection between the first conveyor plate and the first slide rod and the precise control of the first lead screw ensure the positional accuracy of the first conveyor plate and further reduce the risk of deformation.

[0012] Optionally, a rotating rod is fixedly provided on the upper surface of the discharge gate. The rotating rod is located on the side of the two discharge gates that are far apart from each other. The rotating rod is rotatably connected to the cooling box. The end of the rotating rod near the third conveyor belt passes through the cooling box and is coaxially fixedly connected to a turbine. A worm gear meshing with the turbine is rotatably connected to the outer wall of the cooling box. A gear is fixedly connected to one end of the worm gear. A rack meshing with the gear is fixedly connected to the lower end of the first conveyor plate. The rack extends along the moving direction of the third conveyor belt.

[0013] By adopting the above technical solution, the automatic opening and closing of the discharge gates is achieved, improving the automation level of the device. When the first conveyor plate moves along the third conveyor belt, the rack moves accordingly and drives the gear to rotate, which in turn drives the worm gear to rotate synchronously, ultimately causing the worm and its rotating rod to rotate, thereby realizing the opening and closing of the two discharge gates. This design not only reduces manual operation but also ensures the continuity and stability of the cooling and shaping process, further improving production efficiency.

[0014] Optionally, a second conveyor plate that moves along the conveying direction of the first conveyor belt is provided above the third conveyor belt. A second lifting frame that is slidably connected to the second conveyor plate in the vertical direction is provided between the second conveyor plate and the third conveyor belt. Two second guide rods are fixedly provided on the upper end face of the first lifting rod. The upper ends of the second guide rods extend upward through the second conveyor plate. A second lifting cylinder is fixedly provided on the upper end face of the second conveyor plate. The telescopic end of the second lifting cylinder passes through the second conveyor plate and is fixedly connected to the upper end face of the second lifting frame. Several buffer plates are provided on the lower end face of the second lifting frame. Two third guide rods that are slidably connected to the second lifting frame in the vertical direction are fixedly provided on the upper end face of each buffer plate. A buffer spring is sleeved on the guide rod. The buffer spring is located between the buffer plate and the second lifting frame. The upper ends of the third guide rods pass through the second lifting frame and are fixedly connected. A limiting plate is provided above the second lifting frame. A ball head is rotatably connected to the buffer plate along the vertical axis. A second suction cup for adsorbing the car underbody protection plate is provided below the buffer plate. A ball socket that mates with the ball head is fixed on the upper end face of the second suction cup. A second bracket is provided on the outside of the cooling box. A second screw with an axis parallel to the conveying direction of the first conveyor belt is rotatably connected to the second bracket. A second conveyor plate is threadedly connected to the second screw. A second motor for driving the second screw to rotate is fixedly connected to the second bracket. A second slide rod parallel to the axis of the second screw is fixedly connected to the second bracket. The second conveyor plate is slidably connected to the second slide rod. A fourth conveyor belt for conveying the car underbody protection plate to the side opposite to the conveying direction of the first conveyor belt is provided on one side of the cooling box. The end of the fourth conveyor belt near the third conveyor belt is located inside the second bracket.

[0015] By adopting the above technical solution, the second lifting frame between the second conveyor plate and the third conveyor belt can move vertically. The up-and-down movement of the second lifting frame is controlled by the second lifting cylinder, enabling the buffer plate and the second suction cup to accurately adsorb and release the car underbody protection plate. Simultaneously, the second lead screw and second slide bar on the second bracket ensure the precise movement of the second conveyor plate, thereby achieving rapid and continuous transmission of the car underbody protection plate and improving production efficiency. The buffer plate is designed to rotate along the vertical axis and is equipped with a buffer spring. When the second suction cup contacts the car underbody protection plate, the buffer plate can adjust its position within a certain range, reducing impact force and preventing material deformation caused by hard collisions. The ball head and ball socket design further enhances the flexibility of the buffer plate, ensuring uniform force on the car underbody protection plate during adsorption and placement, effectively protecting the shape integrity of the material, and adapting to the adsorption of car underbody protection plates of different shapes, improving the adaptability of the equipment.

[0016] Optionally, a rotary cylinder is fixedly installed on the side of the third conveyor belt away from the cooling box and on the side of the conveyor belt closer to the cooling box, and a pressure plate for pressing down the shaping template is fixedly connected to the telescopic end of the rotary cylinder.

[0017] By adopting the above technical solution, the design of the rotary cylinder and its pressure plate enables the pressure plate to prevent the shaping template from rising along with the car underbody protection plate when the second suction cup adsorbs the car underbody protection plate and the second lifting cylinder drives the car underbody protection plate to rise, thus realizing the separation of the car underbody protection plate and the shaping template.

[0018] Optionally, the lower end of the feed gate is hinged to the cooling box, the lower end of the feed gate is lower than the upper conveying surface of the first conveyor belt, and a feed cylinder is rotatably connected inside the cooling box. The telescopic end of the feed cylinder is rotatably connected to the side of the feed gate located inside the cooling box, and the feed cylinder is located below the feed gate.

[0019] By adopting the above technical solution, the lower end of the feed gate is hinged to the cooling box, allowing the feed gate to open and close flexibly and ensuring that the shaping template smoothly enters the cooling box. Simultaneously, the lower end of the feed gate is lower than the upper conveying surface of the first conveyor belt, effectively preventing jamming of the shaping template during entry and ensuring a continuous and stable production process. Furthermore, the feed cylinder rotatably connected inside the cooling box can precisely control the opening and closing of the feed gate, improving the automation level and operational safety of the equipment.

[0020] Optionally, the cooling device is a cooling fan or a cold air nozzle.

[0021] By adopting the above technical solutions, the cooling device uses cooling fans or cold air nozzles, which can effectively improve cooling efficiency and ensure that the automotive underbody protection plate is rapidly cooled in a short time, thereby achieving high-efficiency batch processing capabilities. At the same time, the evenly distributed cooling device can avoid local overcooling that could lead to material deformation, ensuring the quality stability of the product.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Placing the car underbody protection plate on a matching shaping template avoids material deformation during conveying and cooling. The first conveyor belt transports the car underbody protection plate placed on the shaping template into a cooling box for cooling, improving the automation level of the equipment, reducing manual intervention, and increasing production efficiency. The lifting plates on the four second conveyor belts jointly abut against the four corners of the lower end face of the shaping template, driving multiple shaping templates to rise simultaneously in the cooling box, increasing the cooling box's capacity for batch cooling of car underbody protection plates. The evenly distributed cooling devices inside the cooling box ensure uniform and efficient cooling during the rising of multiple shaping templates. The installation of discharge and inlet doors increases the sealing of the cooling box, reduces heat exchange with the outside environment, reduces energy consumption, and improves cooling efficiency. 2. When the first conveyor belt transports the shaping template into the cooling box, since the first conveyor belt is located outside the cooling box, part of the shaping template cannot be transported into the cooling box by the first conveyor belt. The conveyor motor drives the wheel to rotate and completely transport the shaping template on the first conveyor belt into the cooling box, thereby improving the stability and smoothness of the shaping template transport. 3. The first conveyor plate can move in a direction perpendicular to the first conveyor belt. In conjunction with the first lifting cylinder and the first suction cup, it can quickly and accurately remove the shaped template containing the cooled car underbody protection plate from the cooling box and place it on the third conveyor belt. At the same time, the third conveyor belt can transport the shaped template to the designated position. The whole process is highly automated and improves production efficiency. The sliding connection between the first conveyor plate and the first slide rod and the precise control of the first lead screw ensure the positional accuracy of the first conveyor plate and further reduce the risk of deformation.

[0031] The present application will be further described in detail below with reference to all the accompanying drawings.

[0032] This application discloses a cooling and shaping device for automotive underbody protection plates.

[0033] Reference Figure 1 A cooling and shaping device for an automotive underbody protection plate includes a cooling box 1 and a shaping template 2. Placing the automotive underbody protection plate on the shaping template 2 that is compatible with it can avoid material deformation during transportation and cooling. A first conveyor belt 3 is provided on one side of the cooling box 1. The first conveyor belt 3 is used to transport the shaping template 2, on which the uncooled automotive underbody protection plate is placed, into the cooling box 1.

[0034] Reference Figure 2 A feed inlet is provided on the side wall of the cooling box 1 near the first conveyor belt 3. A feed gate 12 is hinged to the feed inlet, and the lower end of the feed gate 12 is hinged to the cooling box 1. The lower end of the feed gate 12 is lower than the upper conveying surface of the first conveyor belt 3. A feed cylinder 16 is rotatably connected inside the cooling box 1. The telescopic end of the feed cylinder 16 is rotatably connected to the side of the feed gate 12 located inside the cooling box 1, and the feed cylinder 16 is located below the feed gate 12. When the feed cylinder 16 rotates to open the feed gate 12, it will not obstruct the shaping template 2 from entering the cooling box 1, and the upper surface of the feed inlet will not touch the shaping template 2 or the car underbody protection plate. The feed cylinder 16 can precisely control the opening and closing of the feed gate 12, improving the automation level and operational safety of the equipment.

[0035] Reference Figure 2Two horizontally arranged fixed rods 15 are fixed inside the cooling box 1. Two crossbeams are fixed inside the cooling box 1, and the fixed rods 15 are bolted to or welded to the crossbeams. Several rotating wheels 151 are rotatably connected to the fixed rods 15. These rotating wheels 151 are evenly arranged along the conveying direction of the first conveyor belt 3, with their axes extending perpendicular to the conveying direction of the first conveyor belt 3. The outer wall of each rotating wheel 151 abuts against the lower end face of the shaping template 2. A conveyor motor 152 is coaxially fixed to the rotating wheel 151 near the feed gate 12, and the conveyor motor 152 is fixedly connected to the fixed rods 15. When the first conveyor belt 3 conveys the shaping template 2 into the cooling box 1, since the first conveyor belt 3 is located outside the cooling box 1, part of the shaping template 2 cannot be conveyed into the cooling box via the first conveyor belt 3. The conveyor motor 152 drives the rotating wheels 151 to rotate, completely conveying the shaping template 2 from the first conveyor belt 3 into the cooling box 1, improving the stability and smoothness of the shaping template 2's conveying. A sensor can be installed on the side wall of the cooling box 1. When the shaping template 2 is fully inside the cooling box 1 and the distance between it and the closed feed door 12 reaches the required distance, the conveyor motor 152 stops rotating the turntable 151.

[0036] Reference Figure 2 The fixing rod 15 and crossbeam are typically made of high-strength steel to ensure the structural stability and durability. The choice of rotating wheels 151 is also important; polyurethane wheels 151 can be selected because polyurethane has good wear resistance and shock absorption properties, effectively reducing wear and vibration. The number and spacing of the rotating wheels 151 can be adjusted according to actual needs to ensure that the shaping template 2 enters the cooling box 1 smoothly and steadily. The conveyor motor 152 is generally a stepper motor or servo motor. These motors have high precision and fast response speed, enabling precise control of the rotation speed of the rotating wheels 151 to ensure stable conveying of the shaping template 2.

[0037] Reference Figure 2 The cooling box 1 has several cooling devices 13 evenly arranged on its two inner walls, parallel to the conveying direction of the first conveyor belt 3, in both horizontal and vertical directions. These cooling devices 13 can take various forms, such as cooling fans or cooling air nozzles. The cooling fans can be common axial fans or centrifugal fans, which have high airflow and low noise, making them suitable for long-term operation. The cooling air nozzles can use compressed air or liquid nitrogen for cooling, providing a faster cooling effect. The shaping template 2 has clearance grooves to avoid the cooling devices 13.

[0038] Reference Figure 2The cooling box 1 contains four symmetrically arranged second conveyor belts 4 for lifting the shaping templates 2. Each second conveyor belt 4 has a number of lifting plates 41 evenly distributed along its circumference. Two troughs 14 are located on each side of the cooling box 1 parallel to the conveying direction of the first conveyor belt 3. The four second conveyor belts 4 are located within their respective troughs 14. The side of the second conveyor belt 4 closest to the shaping template 2 is flush with the side wall of the cooling box 1, reducing the distance between the shaping template 2 and the side wall of the cooling box 1, thereby reducing the size of the cooling box 1. The width of the shaping template 2 is greater than the distance between the two fixing rods 15, allowing the lifting plates 41 on the four second conveyor belts 4 to abut against the four corners of the lower end face of the shaping template 2, causing multiple shaping templates 2 to rise simultaneously within the cooling box 1. When the lifting plates 41 abut against the shaping mold placed on the rotating wheel 151, the uppermost car underbody protection plate inside the cooling box 1 has just finished cooling.

[0039] Reference Figure 1 The upper end of the cooling box 1 is rotatably connected to two symmetrically arranged discharge gates 11 along the conveying direction perpendicular to the first conveyor belt 3. A rotating rod 111 is fixed on the upper surface of the discharge gate 11. The rotating rod 111 is located on the side of the two discharge gates 11 that are far apart from each other. The rotating rod 111 is rotatably connected to the cooling box 1. The two discharge gates 11 rotate in opposite directions, thereby opening the discharge gates 11 and taking out the cooled shaping mold and the car underbody protection plate.

[0040] Reference Figure 1 and Figure 3 Above the cooling box 1 is a first conveyor plate 5 that moves perpendicular to the conveying direction of the first conveyor belt 3. Between the first conveyor plate 5 and the cooling box 1 is a first lifting frame 51 that slides vertically with the first conveyor plate 5. Two guide rods are fixedly mounted on the upper end of the first lifting rod, with the upper ends of the guide rods extending upward through the first conveyor plate 5. A first lifting cylinder 53 is fixedly mounted on the upper end of the first conveyor plate 5. The telescopic end of the first lifting cylinder 53 passes through the first conveyor plate 5 and is fixedly connected to the upper end of the first lifting frame 51. The lower end of the first lifting frame 51 is provided with several first suction cups 54 for adsorbing the shaping mold 2. The first lifting cylinder 53 pushes the first lifting frame 51 downward, thereby causing the first suction cups 54 to abut against the upper end of the shaping mold. The first suction cups 54 work to hold the shaping mold, and the first lifting cylinder 53 drives the shaping mold and the car underbody protection plate to rise and detach from the cooling box 1.

[0041] Reference Figure 3A first support 55 is provided on the outside of the cooling box 1. The first support 55 has four legs, two of which are fixed to the upper end of the trough 14, and the other two are located on one side of the cooling box 1. The first support 55 is rotatably connected to a first lead screw 551 with its axis perpendicular to the conveying direction of the first conveyor belt 3. The first conveyor plate 5 is threadedly connected to the first lead screw 551. The first motor 553 for driving the first lead screw 551 to rotate is fixedly connected to the first support 55. The first slide rod 552 parallel to the axis of the first lead screw 551 is fixedly connected to the first support 55. The first conveyor plate 5 is slidably connected to the first slide rod 552. A third conveyor belt 31 is provided on one side of the cooling box 1 to convey the shaping template 2 to the end of the first conveyor belt 3 away from the cooling box 1. The third conveyor belt 31 is located between the two ends of the first lead screw 551. The first motor 553 starts, driving the first lead screw 551 to rotate, which in turn moves the first conveyor plate 5, causing the shaping mold and the car underbody protection plate to move horizontally above the third conveyor belt 31. The first lifting cylinder 53 extends downward until the shaping template 2 is placed on the third conveyor belt 31, the first suction cup 54 disengages from the shaping mold, and the first lifting cylinder 53 retracts. This series of designs ensures that the shaping template 2 can be quickly and accurately removed from the cooling box 1 and transported to the designated position. The entire process is highly automated, improving production efficiency. The shaping template 2 can be made of ABS plastic sheet, reducing overall weight and energy consumption, facilitating adsorption by the first suction cup 54, and reducing the suction force required for adsorption by the first suction cup 54.

[0042] Reference Figure 3 and Figure 4 One end of the rotating rod 111 near the third conveyor belt 31 extends out of the cooling box 1 and is coaxially fixedly connected to a turbine 112. The outer wall of the cooling box 1 is rotatably connected to a worm gear 113 that meshes with the turbine 112. One end of the worm gear 113 is fixedly connected to a gear 114. The lower end of the first conveyor plate 5 is fixedly connected to a rack 56 that meshes with the gear 114. The rack 56 extends along the moving direction of the third conveyor belt 31. As the first conveyor plate 5 moves from the third conveyor belt 31 towards the cooling box 1, the rack 56 meshes with the gear 114, thereby driving the worm gear 113 to rotate, which in turn drives the worm wheel to rotate, thus opening the discharge gate 11. Subsequently, the first conveyor plate 5 continues to move towards the cooling box 1, and the rack 56 disengages from the gear 114. Due to the self-locking capability of the worm gear 113, the discharge gate 11 will not close. After the shaping mold and the car underbody protection plate are removed, as the plate moves towards the third conveyor belt 31, the rack 56 drives the gear 114 to rotate in the opposite direction, thereby causing the worm wheel to rotate in the opposite direction and closing the discharge gate 11. This linkage mechanism ensures the automatic opening and closing of the discharge gate 11, improving the automation level of the device.

[0043] Reference Figure 5 and Figure 6Above the third conveyor belt 31, a second conveyor plate 6 is provided that moves along the conveying direction of the first conveyor belt 3. Between the second conveyor plate 6 and the third conveyor belt 31, a second lifting frame 61 is provided that slides vertically with the second conveyor plate 6. Two second guide rods 62 are fixedly mounted on the upper end face of the first lifting rod. The upper ends of the second guide rods 62 extend upward through the second conveyor plate 6. A second lifting cylinder 63 is fixedly mounted on the upper end face of the second conveyor plate 6. The telescopic end of the second lifting cylinder 63 passes through the second conveyor plate 6 and is fixedly connected to the upper end face of the second lifting frame 61. The lower end of the second lifting frame 61... The surface is provided with several buffer plates 66. Each buffer plate 66 has two third guide rods 661 fixedly mounted on its upper surface, which are slidably connected to the second lifting frame 61 in a vertical direction. A buffer spring 662 is sleeved on each guide rod, located between the buffer plate 66 and the second lifting frame 61. The upper end of each third guide rod 661 passes through the second lifting frame 61 and is fixedly fitted with a limiting piece 663. The limiting piece 663 is located above the second lifting frame 61 and prevents the third guide rod 661 from detaching from the second lifting frame 61 under the weight of the car underbody protection plate. A ball head 664 is rotatably connected to each buffer plate 66 along its vertical axis. A second suction cup 64 for adsorbing the car underbody protection plate is located below the buffer plate 66. A ball socket 641 that mates with the ball head 664 is fixedly mounted on the upper surface of the second suction cup 64. The second lifting frame 61 is moved up and down by a second lifting cylinder 63, allowing the buffer plate 66 and the second suction cup 64 to accurately adsorb and release the car underbody protection plate. The buffer plate 66 is designed to rotate along the vertical axis and is equipped with a buffer spring 662. When the second suction cup 64 contacts the car underbody protection plate, the buffer plate 66 can adjust its position within a certain range to reduce impact force and avoid material deformation caused by hard collision. The design of the ball head 664 and the ball socket 641 further enhances the flexibility of the buffer plate 66, ensuring that the car underbody protection plate is subjected to uniform force during adsorption and placement, effectively protecting the shape integrity of the material, and can adapt to the adsorption of car underbody protection plates of different shapes, improving the adaptability of the equipment.

[0044] Reference Figure 5A second support 65 is provided on the outside of the cooling box 1. The second support 65 is rotatably connected to a second lead screw with an axis parallel to the conveying direction of the first conveyor belt 3. The second conveying plate 6 is threadedly connected to the second lead screw 651. A second motor 653 for driving the second lead screw to rotate is fixedly connected to the second support 65. A second slide rod 652 parallel to the axis of the second lead screw is fixedly connected to the second support 65. The second conveying plate 6 is slidably connected to the second slide rod 652. A fourth conveyor belt 32 is provided on one side of the cooling box 1 for conveying the car underbody protection plate to the side opposite to the conveying direction of the first conveyor belt 3. The end of the fourth conveyor belt 32 near the third conveyor belt 31 is located inside the second support 65. A second suction cup 64 picks up the car underbody protection plate, and a second lifting cylinder 63 retracts to detach the car underbody protection plate from the shaping mold. The third conveyor belt 31 transports the shaping mold to the starting point of the first conveyor belt 3 to receive new uncooled car underbody protection plates. The second motor 653 drives the second lead screw to rotate, thereby moving the car underbody protection plate towards the fourth conveyor belt 32. Then, the second lifting cylinder 63 extends and places the car underbody protection plate onto the fourth conveyor belt 32. The second lifting cylinder 63 retracts, the second suction cup 64 disengages from the car underbody protection plate, and the fourth conveyor belt 32 delivers the car underbody protection plate to the next process.

[0045] Reference Figure 7 A rotary cylinder 311 is fixedly installed on both the side of the third conveyor belt away from the cooling box 1 and the side closer to the cooling box 1. A pressure plate 312 for pressing down the shaping template 2 is fixedly connected to the telescopic end of the rotary cylinder 311. The design of the rotary cylinder 311 and its pressure plate 312 ensures that after the second suction cup 64 adsorbs the car underbody protection plate, when the second lifting cylinder 63 lifts the car underbody protection plate, the pressure plate 312 prevents the shaping template 2 from rising along with the car underbody protection plate, thus achieving separation between the car underbody protection plate and the shaping template 2.

[0046] The implementation principle of this embodiment is as follows: through a reasonable arrangement of the cooling device 13 and an advanced conveying system design, efficient cooling and shaping of the automotive underbody protection plate are achieved. The cooling device 13 inside the cooling box 1 ensures uniform and efficient cooling. The design of the second conveyor belt 4 and the lifting plate 41 improves the batch processing capacity of the cooling box 1. The automated control of the inlet gate 12 and the outlet gate 11 reduces manual intervention and improves production efficiency. The overall design not only solves the problems existing in traditional cooling methods, but also greatly improves product quality and production efficiency.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
