Description

[0002] As the world today places increasing demands on lightweight structural materials, weight reduction and energy saving, environmental protection and sustainable development, magnesium-lithium alloy sheets have shown broad application prospects in the transportation, electronics, medical, military, aerospace, and 3C industries (such as mobile phones, notebooks, and aviation device casings) that require lightweight structural materials.

[0003] At present, after the traditional extrusion molding device extrudes the magnesium-lithium alloy plate, it is necessary to manually pry out the plate in the lower mold to separate it, and then unload the plate through the unloading equipment.

DETAILED DESCRIPTION

[0035] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0036] The embodiment of the present invention provides a magnesium-lithium alloy extrusion molding device and method, such as Figure 1-13As shown, the magnesium-lithium alloy extrusion molding device includes: a workbench 1 and a hydraulic cylinder 3 arranged on the workbench 1 for magnesium-lithium alloy extrusion molding, and a group of molds 4 arranged on the workbench 1 and the output rod of the hydraulic cylinder 3, wherein the group of molds 4 consists of an upper mold and a lower mold; a push plate 7 arranged at the bottom of the lower mold for separating the plate; a threaded rod 5 arranged at the bottom of the workbench 1 is rotated to drive the push plate 7 to slide up and down, and a threaded barrel 6 threadedly sleeved on the threaded rod 5, the top of the threaded barrel 6 is detachably connected to the bottom of the push plate 7; a driving mechanism arranged on the hydraulic cylinder 3 and the threaded rod 5 for driving the threaded rod 5 to rotate; and a heat dissipation mechanism arranged on the workbench 1 for heat dissipation of the plate.

[0037] In this embodiment, when the hydraulic cylinder 3 on the workbench 1 performs extrusion molding on the magnesium-lithium alloy, the output rod of the hydraulic cylinder 3 is firstly used to drive the upper mold to press down, and cooperate with the lower mold to complete the molding of the plate. After the molding is completed, the upper mold first slides up and leaves the plate, and the threaded rod 5 is driven to rotate by the driving mechanism. The rotation of the threaded rod 5 drives the threaded barrel 6 with the thread sleeve thereon to move up and down. Since the top of the threaded barrel 6 is detachably connected to the bottom of the push plate 7, the movement of the threaded barrel 6 will drive the push plate 7 to slide up. When the push plate 7 slides up, the plate in the lower mold is lifted up to realize the separation of the plate and the lower mold. The separated plate is unloaded by the unloading mechanism. At the same time, a heat dissipation mechanism is provided on the workbench 1 for dissipating the heat of the plate and reducing the temperature of the processing area. Through the coordinated use of the threaded rod 5, the threaded barrel 6 and the push plate 7, the automatic separation of the plate is realized, the laborious operation of manually prying the plate is avoided, and the production efficiency is improved. The temperature of the processing area is reduced by the use of the heat dissipation mechanism, and the influence of workers being in a high temperature environment for a long time on their health is reduced.

[0038] In a further preferred embodiment of the present invention, a support frame 2 is fixedly installed on the top of the workbench 1, and the support frame 2 is fixedly connected to the hydraulic cylinder 3. A mounting plate is fixedly installed on the output rod of the hydraulic cylinder 3. The mounting plate and the workbench 1 are respectively detachably connected to a group of the molds 4. A support rod for guiding the upper mold is slidably provided on the support frame 2, and the bottom end of the support rod is fixedly connected to the mounting plate.

[0039] In this embodiment, the support rod slides on the support frame 2 to provide guidance for the up and down movement of the hydraulic cylinder 3 and the upper mold, thereby ensuring the stability and accuracy of the extrusion molding process.

[0040] In a further preferred embodiment of the present invention, the driving mechanism includes: a first L-shaped block 8 fixedly mounted on the top of the support frame 2; a rotating rod 9 rotatably mounted on the first L-shaped block 8; a rack 10 fixedly mounted on the top of the mounting plate, and the rack 10 slides through the support frame 2; a connecting gear 11 rotatably mounted on the first L-shaped block 8, and the connecting gear 11 is meshed with the rack 10; a group of first bevel gears 12 fixedly mounted on the rotating rod 9 and the output rod of the connecting gear 11, respectively, and the group of first bevel gears 12 are meshed; a connecting mechanism provided on the rotating rod 9 and the threaded rod 5.

[0041] In this embodiment, after the molding is completed, the output rod of the hydraulic cylinder 3 retracts, and the upper mold slides up and leaves the plate. At this time, the upper mold drives the rack 10 fixedly installed on the top of the mounting plate to slide up. When the rack 10 slides up and meshes with the connecting gear 11, the connecting gear 11 is driven to rotate. A first bevel gear 12 is fixedly sleeved on the output rod of the connecting gear 11. The first bevel gear 12 is meshed with another first bevel gear 12 on the rotating rod 9 rotatably installed on the first L-shaped block 8. The rotating rod 9 is connected to the threaded rod 5 through a connecting mechanism. Therefore, when the bevel gear 12 on the rotating rod 9 rotates, the rotational power is transmitted to the threaded rod 5 through the connecting mechanism.

[0042] After receiving the rotational power, the threaded rod 5 starts to rotate, driving the threaded tube 6 threaded thereon to move upward, lifting the plate in the lower mold, and realizing the separation of the plate from the lower mold. Through the coordinated use of the rack 10, the connecting gear 11 and the first bevel gear 12, the automatic linkage of the upper mold sliding up and the push plate 7 sliding up is realized. When the upper mold slides up and leaves the plate, the push plate 7 is driven to slide up at the same time to perform the plate separation operation, thereby improving production efficiency.

[0043] In a further preferred embodiment of the present invention, the connecting mechanism includes: a connecting rod 14 rotatably installed at the bottom of the workbench 1; a second bevel gear 15 fixedly mounted on the connecting rod 14 and the threaded rod 5, respectively, and the two second bevel gears 15 are meshed with each other; a group of differential sprockets 16 fixedly mounted on the connecting rod 14 and the rotating rod 9, respectively; a connecting chain 17 mounted on a group of the differential sprockets 16, and the connecting chain 17 passes through the workbench 1.

[0044] In this embodiment, a differential sprocket 16 is fixedly sleeved on the rotating rod 9, and the sprocket is connected to another differential sprocket 16 fixedly sleeved on the connecting rod 14 through a connecting chain 17. The second bevel gear 15 on the connecting rod 14 is meshed with the second bevel gear 15 on the threaded rod 5. Therefore, the rotation of the rotating rod 9 is transmitted through the differential sprocket 16, the connecting chain 17 and the second bevel gear 15 on the connecting rod 14, and finally drives the threaded rod 5 to rotate.

[0045] Since the upper part of the rack 10 is not provided with teeth (such as Figure 1 As shown), therefore, when the push plate 7 slides down into the groove of the lower mold, the teeth of the rack 10 have slid down and away from the connecting gear 11. At this time, the rack 10 and the connecting gear 11 do not have the meshing function. Since the teeth of the rack 10 are away from the connecting gear 11, the push plate 7 slides close to the lower mold. Therefore, even if the upper mold continues to slide down, the rack 10 cannot drive the rotating rod 9 to rotate, thereby ensuring that the threaded rod 5 does not rotate. Through the coordinated use of the rack 10, the connecting gear 11, the second bevel gear 15, the differential sprocket 16 and the connecting chain 17, the automatic linkage from sliding up the upper mold to sliding up the push plate 7 is realized.

[0046] In a further preferred embodiment of the present invention, a connection port is opened on the top of the support frame 2, and the connection port is used for the rack 10 to slide, and a guide block 13 is fixedly installed in the connection port, and the guide block 13 is used to guide the rack 10 to move smoothly. The guide block 13 is slidably connected to the rack 10.

[0047] In this embodiment, by opening a connection port at the top of the support frame 2 and fixing the guide block 13 in the connection port, smooth guidance of the rack 10 is achieved, ensuring that the rack 10 can remain stable during the sliding process, thereby ensuring the smoothness and accuracy of the entire drive transmission process.

[0048] In a further preferred embodiment of the present invention, an operating port is opened on the top of the workbench 1, and the operating port is located directly below the lower mold for the threaded barrel 6 to slide up and down. A connecting block 18 is fixedly installed on one side of the operating port, and a guide rod 19 is installed on the threaded barrel 6. The guide rod 19 slides through the connecting block 18, and the guide rod 19 is used to guide the threaded barrel 6 to move smoothly.

[0049] In this embodiment, in order to ensure the stability of the threaded barrel 6 during the up and down sliding process, a connecting block 18 is fixedly installed on one side of the operating port, and a guide rod 19 is installed on the threaded barrel 6. The guide rod 19 slides through the connecting block 18 to play a guiding role, ensuring the smooth movement of the threaded barrel 6.

[0050] In a further preferred embodiment of the present invention, the heat dissipation mechanism includes: a roller conveyor 20 installed on the workbench 1 for conveying plates; a box body 21 installed on the outer shell of the roller conveyor 20; a plurality of heat dissipation blades 22 rotatably installed on the top of the inner wall of the box body 21 for dissipating heat from the plates; a first sprocket 23 fixedly mounted on the plurality of heat dissipation blades 22 respectively; a first chain 24 mounted on the plurality of the first sprockets 23; and a transmission mechanism arranged on the rotating shaft of the roller conveyor 20 and the heat dissipation blades 22 for driving the heat dissipation blades 22 to rotate.

[0051] In this embodiment, after the plate is extruded, it is moved to the roller conveyor 20 by the unloading mechanism, and then it is conveyed to the box 21 by the roller conveyor 20, and the plate is supported by the supporting mechanism so that it is suspended in the box 21. Since the heat dissipation blades 22 rotate synchronously with the rollers on the roller conveyor 20, the roller conveyor 20 will not stop while the plate is suspended. Then, the rotational power of the roller is transmitted to the heat dissipation blades 22 through the transmission mechanism, and through the setting of the first sprocket 23 and the first chain 24, multiple heat dissipation blades 22 are synchronously rotated at high speed to dissipate heat for the plate. The high-speed rotation and synchronous operation of the heat dissipation blades 22 effectively improve the heat dissipation efficiency, ensure that the plate can be quickly cooled after extrusion, and avoid deformation or quality degradation of the plate caused by high temperature. By utilizing the rotational power of the roller conveyor 20 to drive the heat dissipation blades 22 to rotate, no additional power source is required, energy consumption is reduced, and it is in line with the concept of energy saving and environmental protection.

[0052] In a further preferred embodiment of the present invention, the transmission mechanism includes: a round rod 25 rotatably mounted on the top of the box body 21; two differential wheels 26 respectively fixedly mounted on the round rod 25 and any rotating shaft of the roller conveyor 20; a belt 27 mounted on the two differential wheels 26; and a third bevel gear 28 respectively fixedly mounted on the other end of the round rod 25 and the rotating shaft of any cooling fan blade 22, and the two third bevel gears 28 are meshed with each other.

[0053] In this embodiment, when the roller on the roller conveyor 20 rotates, its rotational force is transmitted to the heat dissipation blades 22 through the differential wheel 26 , the belt 27 and the third bevel gear 28 .

[0054] Specifically, the rotational force of the roller is first transmitted to the round rod 25 through the belt 27 and the differential wheel 26. The design of the differential wheel 26 allows the two rotating parts to rotate at different speeds while transmitting torque, which is used here to adapt to the possible speed difference between the roller conveyor 20 and the heat dissipation fan blades 22. The rotational force of the round rod 25 is then transmitted to the rotating shaft of the heat dissipation fan blades 22 through two meshing third bevel gears 28, driving the heat dissipation fan blades 22 to rotate. The heat dissipation fan blades 22 rotate at a high speed in the box body 21, generating airflow to dissipate heat to the suspended plates. At the same time, through the arrangement of the first sprocket 23 and the first chain 24, it is ensured that multiple heat dissipation fan blades 22 can rotate synchronously to improve the heat dissipation efficiency. By utilizing the rotational power of the roller conveyor 20 to drive the heat dissipation fan blades 22 to rotate, no additional power source is required, thereby reducing energy consumption.

[0055] In a further preferred embodiment of the present invention, a connecting frame 29 is fixedly installed on the top of the support frame 2, and the connecting frame 29 is rotatably connected to the rotating rod 9. A plurality of photoelectric detection devices 30 for monitoring the position of the plate are installed on the support frame 2.

[0056] In this embodiment, the introduction of the photoelectric detection device 30 enables the position of the sheet during the extrusion molding process to be accurately monitored, which helps to ensure that the sheet is extruded at the correct position and improve product quality. At the same time, the photoelectric detection device 30 can also be used to detect whether the sheet has completed extrusion molding, thereby triggering subsequent conveying and heat dissipation steps.

[0057] The present invention also provides a method for extrusion molding of a magnesium-lithium alloy, comprising the following steps:

[0058] Step 1: First, place the heated sheet in the groove of the lower mold, then the output rod of the hydraulic cylinder 3 drives the upper mold to press down, and cooperates with the lower mold to complete the molding of the sheet. After the molding is completed, the upper mold first slides up, and when the upper mold rises away from the sheet, it synchronously drives the rack 10 to slide up. When the rack 10 slides up and meshes with the connecting gear 11, it drives the connecting gear 11 to rotate and the first bevel gear 12 to rotate, so that the first bevel gear 12 drives the rotating rod 9 to rotate. Since the rotating rod 9 is connected to the threaded rod 5 through a connecting mechanism, when the bevel gear 12 on the rotating rod 9 rotates, the rotational power is transmitted to the threaded rod 5 through the connecting mechanism, so that the threaded rod 5 rotates, and the rotation of the threaded rod 5 drives the threaded barrel 6 threaded thereon to move up and down. Since the top of the threaded barrel 6 is detachably connected to the bottom of the push plate 7, the movement of the threaded barrel 6 will drive the push plate 7 to slide up. When the push plate 7 slides up, the sheet in the lower mold is lifted up to realize the separation of the sheet and the lower mold. The separated sheet can be unloaded.

[0059] Step 2: After the plate is extruded, it is moved to the roller conveyor 20, and then it is conveyed to the box 21 by the roller conveyor 20, and the plate is suspended in the box 21, and then the rotational power of the roller is transmitted to the heat dissipation fan blades 22 through the transmission mechanism, and through the setting of the first sprocket 23 and the first chain 24, multiple heat dissipation fan blades 22 are synchronously rotated at high speed to dissipate heat for the plate. After the plate is cooled, it is conveyed to the next processing area by the roller conveyor 20 for further processing. In order to further improve the use effect of the device, in addition to the above-mentioned scheme, this scheme also has the following embodiments:

[0060] In another embodiment of the present invention, an electric push rod 31 is fixedly installed on the top of the workbench 1, the electric push rod 31 is located on the right side of the support frame 2, and a placement plate 32 for placing a plate is installed on the electric push rod 31.

[0061] In this embodiment, the worker first places the plate heated to an appropriate temperature on the placement plate 32 to prepare for subsequent extrusion molding.

[0062] When the plate is ready, the unloading mechanism starts to work, and its clamping mechanism 37 clamps the plate. At the same time, the electric push rod 31 starts to slide down, so that the bottom of the plate on the placement plate 32 is suspended in the air, so that the clamping mechanism 37 can more easily clamp the plate and lift it up. After the clamping mechanism 37 clamps the plate, it is transported to the extrusion molding area under the support frame 2, so that the plate is placed on the lower mold for subsequent processing.

[0063] In another embodiment of the present invention, the unloading mechanism includes: a connecting plate 33 fixedly mounted on both sides of the support frame 2; a group of driving wheels 34 rotatably mounted on the two connecting plates 33; a conveying chain 35 sleeved on a group of the driving wheels 34, and the conveying chain 35 is equipped with a first electric telescopic rod 36 for clamping the plate for movement, and a clamping mechanism 37 provided on the first electric telescopic rod 36; a motor 44 fixedly mounted on one side of the connecting plate 33, and the output shaft of the motor 44 is fixedly connected to the output rod of any one of the driving wheels 34.

[0064] In this embodiment, since the unloading mechanism is composed of two sets of driving wheels 34 and a clamping mechanism 37, and the two sets of driving wheels 34 are provided with a chain transmission assembly 45, the chain transmission assembly 45 is composed of a cross bar, four sprockets and two chains, the cross bar is rotatably mounted on the connecting plate 33, the four sprockets are respectively fixedly sleeved on the rotating shaft of each driving wheel 34 of the two sets of driving wheels 34 and the two ends of the cross bar, and the two chains are respectively sleeved on the four sprockets, so that the motor 44 can simultaneously drive the two sets of driving wheels 34 to rotate, so that the two sets of clamping mechanisms 37 can realize synchronous rotation operation;

[0065] When the plate on the placement plate 32 is moved to the lower mold, the driving wheel 34 and the conveying chain 35 first move the clamping mechanism 37 to one side of the placement plate 32. The position of the clamping mechanism 37 can be detected by the photoelectric detection device 30, thereby ensuring that the clamping mechanism 37 is automatically started when it is located at a fixed position, so that the clamping mechanism 37 clamps the plate. At the same time, the electric push rod 31 drives the placement plate 32 to slide down. When the plate moves to the top of the lower mold, it is also detected by the photoelectric detection device 30 located in the support frame 2, so that the clamping mechanism 37 releases the plate. At the same time, the first electric telescopic rod 36 retracts to keep the clamping mechanism 37 away from the plate, so that the plate falls onto the lower mold by its own gravity, which is convenient for subsequent extrusion molding processing;

[0066] Since the conveying chain 35 rotates in a closed circular shape, the height at which the clamping mechanism 37 slides above the driving wheel 34 and below the driving wheel 34 is different. When unloading the formed sheet, the clamping mechanism 37 needs to slide above the driving wheel 34 to ensure that the sheet is away from the lower mold when unloading. When loading the sheet to be processed, the clamping mechanism 37 needs to slide below the driving wheel 34 to ensure that the sheet is close to the lower mold, which is conducive to placing the sheet into the groove of the lower mold. During the whole process, the photoelectric detection equipment 30 continuously monitors the position and state of the sheet to ensure that the sheet is clamped, conveyed, extruded and unloaded at the correct position.

[0067] In another embodiment of the present invention, the clamping mechanism 37 includes: a connecting box fixedly installed on the output end of the first electric telescopic rod 36: a fixed block 40 fixedly installed on one side of the connecting box for limiting the plate; a clamping plate 41 rotatably installed on the connecting box for cooperating with the fixed block 40 to clamp the plate; a second electric telescopic rod 42 fixedly installed in the connecting box, and a push block 43 for pushing the clamping plate 41 to rotate is installed on the output rod of the second electric telescopic rod 42; a magnet bar installed at the bottom of the clamping plate 41 for fixing the clamping plate 41 on the push block 43, and the magnet bar is adsorbed on the push block 43.

[0068] In this embodiment, when it is necessary to clamp the plate, the clamping mechanism 37 of the unloading mechanism starts to work. First, the first electric telescopic rod 36 is started to drive the clamping mechanism 37 to move so that the fixed block 40 is located below the plate. Then, the second electric telescopic rod 42 is started to drive the push block 43 to slide upward. At this time, since a magnet bar is installed at the bottom of the clamping plate 41 and the magnet bar is adsorbed on the push block 43, the upward sliding of the push block 43 will drive the left end of the clamping plate 41 to rotate upward, while the right end rotates downward, thereby clamping the plate between the clamping plate 41 and the fixed block 40.

[0069] After the clamping mechanism 37 clamps the plate, it conveys the plate to the top of the lower mold as the conveying chain 35 moves. The adsorption design of the magnet bar and the push block 43 makes the clamping plate 41 more stable during the rotation process, ensuring that the clamping plate 41 will not separate from the push block 43.

[0070] In another embodiment of the present invention, a ring frame 38 is fixedly installed on one side of the connecting plate 33 , a connecting member 39 is slidably provided on the ring frame 38 , and the connecting member 39 is fixedly connected to the first electric telescopic rod 36 .

[0071] In this embodiment, when the conveying chain 35 drives the clamping mechanism 37 to move, the first electric telescopic rod 36 drives the connecting piece 39 to rotate along the annular frame 38, so that the connecting piece 39 supports the first electric telescopic rod 36, ensuring that the first electric telescopic rod 36 does not affect the conveying chain 35 when moving. By introducing the design of the annular frame 38 and the connecting piece 39, a stable sliding track and support structure are provided for the first electric telescopic rod 36, which not only enhances the stability and durability of the first electric telescopic rod 36, but also ensures that it does not affect the normal operation of the conveying chain 35 when moving.

[0072] In another embodiment of the present invention, a plate adjustment mechanism is provided on the workbench 1, and the plate adjustment mechanism includes: a group of connecting boxes 46 installed on the top of the workbench 1, the number of the connecting boxes 46 in a group of four, and distributed on the four sides of the lower mold; an adjustment plate 50 slidably arranged above the connecting box 46, for adjusting the plate to the groove body of the lower mold; two discs 47 rotatably arranged in the connecting box 46; protrusions 48 respectively installed on one side of the two discs 47; connecting frames 49 respectively mounted on the two protrusions 48 for driving the adjustment plate 50 to reciprocate left and right; a linkage mechanism arranged on the connecting box 46 and the support frame 2 for driving the disc 47 and the rotating rod 9 to rotate synchronously.

[0073] In this embodiment, when the sheet is placed on the lower die, the hydraulic cylinder 3 drives the lower die to slide down, and at the same time, the rotating rod 9 starts to rotate through the rack 10 and the connecting gear 11, and the rotating force of the rotating rod 9 is transmitted to the disc 47 through the linkage mechanism, so that the disc 47 starts to rotate. Since the disc 47 is arranged vertically and the protrusion 48 is far away from the center of the disc, when the disc 47 rotates, the protrusion 48 will drive the connecting frame 49 to move left and right. At the same time, the protrusion 48 slides up and down in the connecting frame 49, so that the connecting frame 49 drives the adjustment plate 50 to slide close to the lower die, and the adjustment plate 50 pushes the sheet part outside the notch into the notch, ensuring that the sheet is completely located in the groove body of the lower die, which is convenient for the subsequent extrusion molding operation of the sheet. Through the design of the sheet adjustment mechanism, including the connecting box 46, the disc 47, the protrusion 48, the connecting frame 49 and the adjustment plate 50 and other components, the precise adjustment of the sheet is achieved, ensuring that the sheet is completely located in the groove body of the lower die, and improving the quality and accuracy of the extrusion molding.

[0074] In another embodiment of the present invention, a connecting rod 51 is fixedly installed in the connecting box 46, and a connecting block 52 is slidably sleeved on the connecting rod 51. The connecting block 52 is fixedly connected to the connecting frame 49, and the connecting block 52 extends out of the connecting box 46 and is detachably connected to the adjustment plate 50.

[0075] In this embodiment, the smooth movement of the adjustment plate 50 is achieved by fixedly installing the connecting rod 51 in the connecting box 46 and slidingly sleeved the connecting block 52 on the connecting rod 51. The connecting block 52 is fixedly connected to the connecting frame 49, ensuring that the movement of the connecting frame 49 can be smoothly transmitted to the adjustment plate 50. The design of the plate adjustment mechanism enables the adjustment plate 50 to accurately push the plate into the groove body of the lower mold, ensuring the correct positioning of the plate before extrusion molding.

[0076] In another embodiment of the present invention, the linkage mechanism includes: a plurality of second L-shaped blocks 53 fixedly mounted on the workbench 1; a plurality of first fixing rods 54 rotatably mounted on the plurality of second L-shaped blocks 53, the plurality of first fixing rods 54 are respectively rotatably connected to a group of the connecting boxes 46, and the plurality of first fixing rods 54 are respectively fixedly connected to the disc 47; a fourth bevel gear 58 fixedly sleeved on the other end of the plurality of first fixing rods 54, the plurality of fourth bevel gears 58 are divided into four groups, and the four groups of fourth bevel gears 58 are meshed; a second fixing rod 55 rotatably mounted in the connecting box 46, the second fixing rod 54 is rotatably mounted on the second L-shaped blocks 53, the plurality of first fixing rods 54 are respectively rotatably connected to a group of the connecting boxes 46, and the plurality of first fixing rods 54 are respectively fixedly connected to the disc 47; The rod 55 is located on one side of the disc 47; the third sprocket 56 is fixedly mounted on the first fixed rod 54 and the second fixed rod 55 respectively, and the two third sprockets 56 are mounted with a third chain 57; a connecting rod 59 is rotatably mounted on one side of the support frame 2, and one end of the connecting rod 59 is fixedly mounted with a connecting sprocket 61, and the connecting sprocket 61 is meshed with the connecting chain 17; a fifth bevel gear 60 is fixedly mounted on the other end of the connecting rod 59 and the second fixed rod 55 respectively, and the two fifth bevel gears 60 are meshed; a group of limiting wheels 62 is rotatably mounted on one side of the support frame 2 for limiting the connecting chain 17.

[0077] In this embodiment, when the rotating rod 9 rotates, the connecting chain 17 thereon will synchronously drive the connecting sprocket 61 on the connecting rod 59 on one side of the support frame 2 to rotate synchronously. The other end of the connecting rod 59 is fixedly sleeved with a fifth bevel gear 60, which meshes with the fifth bevel gear 60 on the second fixed rod 55. Therefore, when the connecting rod 59 rotates, the second fixed rod 55 will be driven to rotate through the meshing action of the fifth bevel gear 60. Since the second fixed rod 55 is connected to the first fixed rod 54 through the third sprocket 56 and the third chain 57, the rotation of the second fixed rod 55 will drive the first fixed rod 54 to rotate synchronously. The rotation of the first fixed rod 54 will then drive the disk 47 to rotate. The protrusion 48 on the disk 47 will drive the connecting frame 49 to reciprocate left and right. The movement of the connecting frame 49 is transmitted to the adjustment plate 50 through the connecting block 52, so that the adjustment plate 50 slides smoothly close to the lower mold and pushes the plate into the slot.

[0078] In another embodiment of the present invention, a third electric telescopic rod 63 is fixedly installed on the top of the box body 21, a guide wheel 64 for guiding the plate is arranged below the third electric telescopic rod 63, a spring 65 for buffering the guide wheel 64 is installed on the third electric telescopic rod 63, and the bottom end of the spring 65 is connected to the guide wheel 64.

[0079] In this embodiment, when the plate is transported to the box body 21 through the roller conveyor 20 for heat dissipation treatment, it will encounter the third electric telescopic rod 63 and the guide wheel 64 below it. The third electric telescopic rod 63 can be extended and retracted as needed to adjust the height of the guide wheel 64 to adapt to plates of different heights after forming. The guide wheel 64 is designed to guide the plate to smoothly enter the box body 21 to ensure that the plate will not be offset or collided during the transportation process. At the same time, when the heat dissipation fan blades 22 dissipate heat to it, it can ensure that the plate will not be displaced.

[0080] In another embodiment of the present invention, a supporting mechanism for supporting the plate and suspending it is provided in the box body 21, and the supporting mechanism includes: a supporting plate 66 rotatably installed in the operating port of the box body 21; a connecting cylinder 67 fixedly installed on the top of the box body 21; a pressure rod 68 installed on the connecting cylinder 67 for pushing the supporting plate 66 to rotate; a limit block 69 installed on one side of the box body 21 for guiding the pressure rod 68, and the limit block 69 is slidably sleeved on the pressure rod 68.

[0081] In this embodiment, when it is necessary to support the plate, the connecting cylinder 67 is started, causing it to drive the pressure rod 68 to slide down. The pressure rod 68 transmits power to the support plate through its connection with the support plate 66, causing one side of the pressure rod to rotate upward and lift the clamped plate upward so that the plate is suspended in the air, after which the heat dissipation operation can be carried out. After the operation is completed, the connecting cylinder 67 is extended and retracted, driving the pressure rod 68 to move upward, and the support plate rotates downward and returns to its original position, preparing for the next operation.

[0082] In another embodiment of the present invention, protective covers 70 are installed on the box 21, the workbench 1 and the support frame 2, and multiple protective covers 70 are respectively covered on the connecting chain 17, the connecting rod 14, the belt 27 and the pressure rod 68.

[0083] In this embodiment, the introduction of the protective cover 70 significantly improves the safety of the entire device. By preventing operators or other personnel from accidentally contacting the moving parts, the risk of injury accidents can be greatly reduced. The protective cover 70 can also prevent debris or dust from entering the interior of the moving parts, thereby extending the service life of these parts and reducing maintenance costs.
