Description

Technical Field

[0001] The present invention relates to the technical field of punching equipment, and specifically relates to an aluminum pole piece punching device. Background Art

[0002] In the aluminum pole piece punching process in a lithium battery production workshop, the defects of traditional punching devices significantly restrict production efficiency and product quality. The specific problems are as follows: 1. High manual operation intensity and prominent safety hazards Traditional devices rely on manual operation of fixtures to fix the aluminum substrate. In high-speed punching scenarios, operators need to frequently bend down to adjust the fixtures, with frequent repetitive movements and high work intensity, which may lead to occupational health problems such as lumbar muscle strain. In addition, it is difficult to accurately control the pressing force manually. If it is too loose, the substrate may slide, and if it is too tight, the surface of the substrate may be damaged, affecting the adhesion of the subsequent electrode coating. 2. High electrical control cost and frequent failures Some traditional devices use electrical control to clamp and press the fixtures, and need to be equipped with electronic components such as sensors and controllers, increasing the initial procurement cost. Moreover, in the lithium battery production environment with high dust and high humidity, electrical components are prone to moisture absorption or dust accumulation, which may lead to control failures.

[0003] Considering the above problems, in large-scale production of power batteries, traditional punching devices have poor production capacity and product quality due to problems such as manual dependence and electrical failures. These problems are particularly prominent in the lithium battery industry that pursues high production capacity and high precision, and it is urgent to improve the reliability of the equipment through mechanical linkage and automation design. Summary of the Invention

[0004] To solve the technical problems in the background art, the present invention proposes an aluminum pole piece punching device.

[0005] An aluminum pole piece punching device proposed by the present invention includes a frame. An activity seat driven by a lift is installed at the upper end of the inner cavity of the frame. A punching die located directly above the bearing table is installed at the bottom of the activity seat. A bearing plate for placing the aluminum substrate is installed at the upper end of the bearing table. At least a pair of pressing components are installed on the upper end surface of the bearing plate for pressing at least one set of opposite sides of the aluminum substrate. A plug board is installed at the bottom of the activity seat for inserting into the bearing plate to drive the pressing components to press the aluminum substrate before punching.

[0006] As a further optimized solution of the present invention, the pressing assembly includes a support frame installed on the upper end surface of the bearing plate. The support frame is U-shaped with an opening facing downwards and is erected above the edge of the aluminum substrate. A pressing plate for pressing the edge of the aluminum substrate is installed on the U-shaped bottom surface of the support frame. The interior of the support frame has a U-shaped cavity and is equipped with a lifting mechanism. The upper end of the pressing plate extends into the U-shaped cavity and is connected to the output end of the lifting mechanism. The input end of the lifting mechanism is matched with the lower end of the insertion plate.

[0007] As a further optimized solution of the present invention, the pressing plate includes a bottom plate arranged parallel above the edge of the aluminum substrate. An extension plate is installed at the upper end of the bottom plate. The upper end of the extension plate slides and extends into the support frame and is equipped with a movable plate. The movable plate is connected to the output end of the lifting mechanism.

[0008] As a further optimized solution of the present invention, the lifting mechanism includes a threaded rod, a transmission gear, and a transmission rack. The threaded rod is rotatably installed on the side of the U-shaped cavity of the support frame. One end of the pressing plate located inside the U-shaped cavity extends horizontally and is threadedly sleeved on the upper end of the threaded rod. The interior of the upper end of the bearing plate has a transmission cavity arranged horizontally and communicating with the lower end of the side of the U-shaped cavity. The lower end of the threaded rod extends into the transmission cavity and is equipped with a transmission gear. The transmission rack is slidably arranged in the transmission cavity and one end thereof is meshed and connected with the transmission gear. The other end of the transmission rack is in transmission cooperation with the lower end of the insertion plate through a transmission component arranged in the transmission cavity.

[0009] As a further optimized solution of the present invention, the transmission component includes a fixed ring fixed in the transmission cavity. A driving rod is slidably sleeved in the inner circle of the fixed ring. One end of the driving rod extends towards the transmission gear and is fixed to the transmission rack. The other end of the driving rod extends in the opposite direction and is equipped with a movable block. The movable block is connected to the fixed ring through a return spring. The free end of the movable block is spherical and is in transmission cooperation with the lower end of the insertion plate.

[0010] As a further optimized solution of the present invention, a jack is opened on the upper end surface of the bearing plate opposite to the lower end of the insertion plate, and the side part of the jack is connected to the end of the transmission cavity far from the transmission gear. The spherical end of the movable block extends into the jack. When the lower end of the insertion plate slides and inserts into the jack, the movable block will be pushed into the transmission cavity, causing the driving rod to drive the transmission rack to move and drive the transmission gear and the threaded rod to rotate, thereby adjusting the height of the pressing plate.

[0011] As a further optimized solution of the present invention, the bearing platform is a hollow box body with an open top and an inner diameter adapted to the outer diameter of the bearing plate. The lower end of the bearing plate slides and extends into the bearing platform and is connected to the inner cavity bottom surface of the bearing platform through a buffer mechanism.

[0012] As a further optimized solution of the present invention, the buffer mechanism includes at least two buffer units, and the at least two buffer units are symmetrically distributed at the lower end of the inner cavity of the carrier table. The buffer unit includes a guide plate, a guide rod, and a first spring. The lower end of the guide rod is fixed to the bottom surface of the inner cavity of the carrier table, the upper end of the guide rod slidably penetrates the carrier plate and is slidably sleeved with the lower end of the inner cavity of the guide post. One end of the guide plate is installed at the bottom of the carrier plate and is slidably sleeved on the guide rod, and the other end of the guide plate is slidably assembled with the guide groove on the inner wall of the carrier table. The first spring is sleeved on the guide rod and is fixedly connected between the guide plate and the bottom surface of the inner cavity of the carrier table.

[0013] As a further optimized solution of the present invention, a buffer assembly is installed on the side of the frame. The guide groove is vertically arranged and penetrates left and right. One end of the guide plate away from the guide rod passes through the guide groove and extends to the side of the carrier table and is connected to the input end of the buffer assembly.

[0014] As a further optimized solution of the present invention, the buffer assembly includes a movable rod, a wedge block, a stop block, and a second spring. The movable rod is slidably sleeved on the two side columns of the frame. One end of the movable rod extends horizontally towards the carrier table and is installed with a wedge block, and the inclined surface of the wedge block is arranged below the guide plate. The other end of the movable rod extends reversely to the outside of the frame and is installed with a stop block. The second spring is sleeved on the movable rod and is fixedly connected between the frame and the stop block.

[0015] As a further optimized solution of the present invention, a base is installed at the bottom of the inner cavity of the frame. A waste collection box that can be taken outwards is arranged in the base. The carrier table is installed on the upper end surface of the base and the two are communicated through a waste falling port. The middle of the carrier plate has a punching hole so that the punching waste can flow into the waste collection box through the punching hole and the waste falling port for collection.

[0016] As a further optimized solution of the present invention, fixing blocks are installed on the upper end surface of the base on both sides of the carrier table. Horizontal sliding grooves adapted to the wedge blocks are opened on the upper end surfaces of the fixing blocks, and the lower end of the wedge block is slidably assembled with the horizontal sliding grooves.

[0017] As a further optimized solution of the present invention, a card slot adapted to the free end of the guide plate is opened at the upper end of the fixing block, and the side of the card slot is communicated with the lower end of the guide groove so that after secondary buffering, the guide plate can continue the third-stage stroke for the final punching.

[0018] As a further optimized solution of the present invention, a cooling circuit is provided inside the punching die. The inlet end and the outlet end of the cooling circuit are respectively connected to a circulating liquid cooling device, and a valve is installed at the inlet end. A control console is also installed on the side of the column of the frame. The control knob of the valve is arranged on the control console and is fixedly connected to the end of the control gear shaft on the control console. A control rack meshingly connected to the control gear is installed at the bottom of the stop block.

[0019] The aluminum pole piece punching device proposed by the present invention has the following beneficial effects: (1) Through the insertion of the plug board at the bottom of the movable seat into the bearing plate, the pressing component is driven to automatically press the opposite sides of the aluminum substrate. Before punching, the plug board descends with the movable seat and inserts into the jack, pushing the movable block to drive the transmission rack and the threaded rod to rotate, so that the pressing plate presses down to fix the aluminum substrate. The whole process does not require manual intervention or complex electrical components, and realizes automatic pressing through mechanical linkage, reducing the operation intensity, eliminating the safety hazards of manual operation, and at the same time avoiding the downtime maintenance caused by electrical faults, improving the product quality and production efficiency; (2) The bearing plate is connected to the bearing table through a buffer mechanism. During punching, the buffer mechanism absorbs the impact force, reducing the damage to the aluminum substrate and the mold caused by vibration. And buffer components are arranged on both sides of the bearing table. The wedge-shaped blocks of the buffer components cooperate with the guide plates, and the second spring provides secondary buffering, further reducing the punching noise and equipment loss. This multi-stage buffer design prolongs the service life of the mold and the bearing table, and at the same time improves the stability of the punching process, ensuring the punching accuracy of the aluminum pole piece; (3) The punching holes of the bearing plate are communicated with the waste falling ports of the bearing table and the base, and the punching waste directly falls into the waste collection box. This design avoids the accumulation of waste affecting the punching operation, keeps the working area clean, reduces the frequency of manual cleaning, optimizes the production process, and is especially suitable for large-scale continuous punching scenarios, improving the workshop management efficiency; (4) The punching die is internally provided with a cooling circuit, which is cooled by a circulating liquid cooling device to control the punching temperature, avoiding the deformation of the aluminum substrate due to high temperature, improving the punching accuracy and surface quality. At the same time, the cooling circuit reduces the temperature of the mold, reduces thermal wear, prolongs the mold replacement cycle, reduces the production cost. The control gear of the control console is linked with the control rack of the stop block, and automatically adjusts the cooling flow during the buffering process, so as to cool down the punching die before punching, reducing the influence of heat on the pole piece punching, and further optimizing the punching process.

Detailed implementation manners

[0023] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar symbols represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

Moreover, the first feature being "above", "over" and "on" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature.

[0025] Such as Figure 1 and Figure 2As shown in the figure, an aluminum pole piece punching device includes a frame 1. An activity seat 2 driven by a lift is installed at the upper end of the inner cavity of the frame 1. A punching die 3 located directly above the bearing table 4 is installed at the bottom of the activity seat 2. It is characterized in that a bearing plate 5 for placing an aluminum substrate 6 is installed at the upper end of the bearing table 4. At least a pair of pressing components 8 are installed on the upper end surface of the bearing plate 5 for pressing at least a set of opposite sides of the aluminum substrate 6. A plug board 9 is installed at the bottom of the activity seat 2 for inserting into the bearing plate 5 to drive the pressing components 8 to press the aluminum substrate 6 before punching; Aiming at the problems of high labor intensity of manually fixing the aluminum substrate and high failure rate of electrical control in the traditional punching device, this design realizes automatic pressing through mechanical linkage. When the activity seat 2 descends, the plug board 9 is inserted into the jack 20 of the bearing plate 5, driving the pressing components 8 to automatically press the opposite sides of the aluminum substrate 6; Before punching, the plug board 9 descends with the activity seat 2. Without manual operation or electrical components, the pressing components 8 can be pressed down to fix the aluminum substrate through the mechanical structure, eliminating the safety hazards of manual operation, and at the same time avoiding shutdown caused by electrical failures, improving production efficiency and safety.

[0026] Specifically, as Figure 6 shown, the pressing component 8 includes a support frame 81 installed on the upper end surface of the bearing plate 5. The support frame 81 is U-shaped with the opening facing downwards and is erected above the edge of the aluminum substrate 6. A pressing plate 82 for pressing the edge of the aluminum substrate 6 is installed on the U-shaped bottom surface of the support frame 81. The inside of the support frame 81 has a U-shaped cavity and a lifting mechanism is installed. The upper end of the pressing plate 82 extends into the U-shaped cavity and is connected to the output end of the lifting mechanism. The input end of the lifting group mechanism cooperates with the lower end of the plug board 9; The U-shaped support frame 81 has a stable structure, which is convenient for accurately pressing the edge of the aluminum substrate 6. The lifting mechanism is linked with the plug board 9. When the plug board 9 is inserted into the jack 20, it pushes the lifting mechanism to act, driving the pressing plate 82 to descend and press the edge of the aluminum substrate. The pressing plate 82 can be made of elastic material, adapting to the surface flatness of the aluminum substrate during pressing, avoiding hard pressing damage, and at the same time ensuring that the aluminum substrate is firmly fixed during the punching process to prevent displacement from affecting the punching accuracy.

[0027] Further, the pressing plate 82 includes a bottom plate 821 arranged in parallel above the edge of the aluminum substrate 6. An extension plate 822 is installed at the upper end of the bottom plate 821. The upper end of the extension plate 822 slides and extends into the support frame 81 and an activity plate 823 is installed. The activity plate 823 is connected to the output end of the lifting mechanism. By driving the lifting of 823 through the lifting mechanism, the height of 821 is adjusted to press and position the edge of the aluminum substrate 6 below; Further, as Figure 7As shown in the figure, the lifting mechanism includes a threaded rod 83, a transmission gear 84, and a transmission rack 85. The threaded rod 83 is rotatably installed on the side of the U-shaped cavity of the support frame 81. One end of the pressing plate 82 located inside the U-shaped cavity extends horizontally and is threadedly sleeved with the upper end of the threaded rod 83. Inside the upper end of the bearing plate 5, there is a transmission cavity 21 arranged horizontally and communicating with the lower end of the side of the U-shaped cavity. The lower end of the threaded rod 83 extends into the transmission cavity 21 and is installed with the transmission gear 84. The transmission rack 85 is slidably arranged in the transmission cavity 21, and one end is meshed and connected with the transmission gear 84. The other end of the transmission rack 85 is in transmission cooperation with the lower end of the plug plate 9 through a transmission component arranged in the transmission cavity 21; When the plug plate 9 descends, it pushes the transmission rack 85 to move horizontally through the transmission component, drives the transmission gear 84 and the threaded rod 83 to rotate, so that the pressing plate 82 moves downward. The threaded design of the threaded rod 83 can convert the horizontal movement of the transmission rack 85 into the vertical movement of the pressing plate 82, and amplify the driving force through the gear-rack transmission, ensuring that even when the size of the aluminum substrate is large, the pressing plate 82 can provide sufficient pressing force to prevent the substrate from sliding during punching.

[0028] Furthermore, as Figure 6 shown, the transmission component includes a fixed ring 86 fixed in the transmission cavity 21. A driving rod 87 is slidably sleeved in the inner circle of the fixed ring 86. One end of the driving rod 87 extends towards the transmission gear 84 and is fixed to the transmission rack 85. The other end of the driving rod 87 extends in the opposite direction and is installed with a movable block 88. The movable block 88 is connected with the fixed ring 86 through a return spring 89. The free end of the movable block 88 is spherical and is in transmission cooperation with the lower end of the plug plate 9; The spherical design of the movable block 88 forms a sliding fit with the lower end of the plug plate 9. When the plug plate 9 moves downward and contacts the movable block 88, the spherical surface is pressed and pushes the driving rod 87 to move into the transmission cavity 21, compressing the return spring 89, and at the same time driving the transmission rack 85 to move, so as to realize the rotation of the threaded rod 83. After punching is completed, the movable seat 2 drives the plug plate 9 to move upward and reset. The return spring 89 loses the external force and pushes the movable block 88 to reset, so that the pressing plate 82 releases the aluminum substrate. This elastic transmission design can buffer the impact force at the moment of punching, avoid rigid collision and damage to components, and at the same time ensure the smooth and reliable transmission process.

[0029] Furthermore, as Figure 6 shown, a jack 20 opposite to the lower end of the plug plate 9 is opened on the upper end surface of the bearing plate 5, and the side part of the jack 20 is connected to the end of the transmission cavity 21 far from the transmission gear 84. The spherical end of the movable block 88 extends into the jack 20. When the lower end of the plug plate 9 slides and inserts into the jack 20, it will push the movable block 88 into the transmission cavity 21, so that the driving rod 87 drives the transmission rack 85 to move and drives the transmission gear 84 and the threaded rod 83 to rotate, thereby adjusting the height of the pressing plate 82; The communication design between the jack 20 and the transmission cavity 21 ensures the precise linkage between the plug board 9 and the transmission component. When the plug board 9 is inserted, the movable block 88 is pushed into the transmission cavity 21. Through the transmission of the driving rod 87 and the transmission rack 85, the threaded rod 83 rotates by a certain angle, precisely controlling the descending height of the pressing plate 82, thereby precisely adjusting the pressing force. This not only ensures the firm fixation of the aluminum substrate but also avoids substrate deformation caused by excessive pressure. It should be noted that the bottom end of the jack 20 extends beyond the bottom surface of the transmission cavity 21 and continues to extend into the inside of the carrier plate 5, and the extension length is greater than the thickness of the aluminum substrate 6. When the lower end of the plug board 9 is inserted into the jack 20 and the movable block 88 is completely pushed into the transmission cavity 21, the pressing plate 82 moves completely downward to complete the pressing of the aluminum substrate. Then, the movable seat 2 drives the punching die 3 to continue moving downward, and the plug board 9 also moves downward synchronously. The punching die 3 performs punching on the aluminum substrate 6, and the extended section of the jack 20 provides space for the plug board 9 to continue moving downward.

[0030] As Figure 2 shown, the carrier table 4 is a hollow box body with an open top, and its inner diameter is adapted to the outer diameter of the carrier plate 5. The lower end of the carrier plate 5 slides and extends into the carrier table 4 and is connected to the inner cavity bottom surface of the carrier table 4 through a buffer mechanism. The sliding fit design between the hollow carrier table 4 and the carrier plate 5, combined with the buffer mechanism, can effectively absorb the impact force during punching. When the punching die 3 contacts the aluminum substrate, the carrier plate 5 compresses the buffer mechanism downward, reducing the vibration transmitted to the frame 1, reducing equipment wear and noise. At the same time, it avoids displacement or deformation of the aluminum substrate due to impact, improving the punching accuracy and equipment life.

[0031] Specifically, as Figure 2 and Figure 4 shown, the buffer mechanism includes at least two buffer units. At least two buffer units are symmetrically distributed at the lower end of the inner cavity of the carrier table 4. The buffer unit includes a guide plate 11, a guide rod 14, and a first spring 15. The lower end of the guide rod 14 is fixed to the inner cavity bottom surface of the carrier table 4. The upper end of the guide rod 14 slides through the carrier plate 5 and is slidably sleeved with the inner cavity lower end of the guide post 7. One end of the guide plate 11 is installed at the bottom of the carrier plate 5 and slidably sleeved on the guide rod 14. The other end of the guide plate 11 is slidably assembled with the guide groove 16 on the inner wall of the carrier table 4. The first spring 15 is sleeved on the guide rod 14 and fixedly connected between the guide plate 11 and the inner cavity bottom surface of the carrier table 4. The symmetrically distributed buffer units provide uniform buffer force through the guide rod 14 and the first spring 15. The guide plate 11 slides in the guide groove 16 to ensure the vertical lifting of the carrier plate 5 and avoid tilting. During punching, the first spring 15 compresses to absorb the impact energy, and the guide rod 14 restricts the lateral movement of the carrier plate 5 to ensure that the aluminum substrate remains horizontal during punching, improving the flatness and accuracy of the punching surface.

[0032] Further, as Figure 1 and Figure 2 shown, a buffer assembly 10 is installed on the side of the frame 1. The guide groove 16 is vertically arranged and penetrates through left and right. One end of the guide plate 11 away from the guide rod 14 passes through the guide groove 16 and extends to the side of the carrier table 4 and is connected to the input end of the buffer assembly 10; The buffer assembly 10 is linked with the guide plate 11 to form a secondary buffer. When the carrier plate 5 descends, the guide plate 11 drives the buffer assembly 10 to act through the guide groove 16, further absorbing the impact energy. For example, in the scenario of large-tonnage punching, the multi-stage buffer design can significantly reduce the vibration amplitude of the frame 1, protect the mold and the aluminum substrate, and at the same time extend the service life of the buffer mechanism and reduce the maintenance frequency.

[0033] Further, the buffer assembly 10 includes a movable rod 101, a wedge block 102, a stop block 103 and a second spring 104. The movable rod 101 is slidably sleeved on the two side columns of the frame 1. One end of the movable rod 101 extends horizontally towards the carrier table 4 and is provided with the wedge block 102, and the inclined surface of the wedge block 102 is arranged below the guide plate 11. The other end of the movable rod 101 extends reversely to the outside of the frame 1 and is provided with the stop block 103. The second spring 104 is sleeved on the movable rod 101 and is fixedly connected between the frame 1 and the stop block 103; The inclined surface of the wedge block 102 cooperates with the guide plate 11 to convert the vertical displacement of the carrier plate 5 into the horizontal displacement of the movable rod 101, and absorbs energy through the elastic deformation of the second spring 104. When the guide plate 11 descends, it pushes the wedge block 102 to move outwards, compressing the second spring 104 to form a buffer in the horizontal direction, further reducing the punching noise and vibration, which is especially suitable for the workshop environment with high requirements for noise and precision.

[0034] Specifically, as Figure 2 shown, a base 12 is installed at the bottom of the inner cavity of the frame 1. A waste collection box 13 that can be taken outwards is arranged in the base 12. The carrier table 4 is installed on the upper end surface of the base 12 and the two are communicated through a waste falling port 19. The middle part of the carrier plate 5 has a punching hole so that the punching waste can flow into the waste collection box 13 through the punching hole and the waste falling port 19 for collection; The punching waste directly falls into the waste collection box 13 through the punching hole and the waste falling port 19 of the carrier plate 5, avoiding the accumulation of waste in the punching area and affecting the operation. The removable waste collection box 13 is convenient for regular cleaning. For example, in continuous punching operations, the full waste collection box can be quickly replaced to maintain the continuity of the production process, and at the same time keep the workshop clean and reduce potential safety hazards.

[0035] Specifically, as Figure 2As shown in the figure, fixing blocks 17 are installed on the upper end surface of the base 12 on both sides of the bearing platform 4. Horizontal chutes adapted to the wedge blocks 102 are provided on the upper end surfaces of the fixing blocks 17, and the lower ends of the wedge blocks 102 are slidably assembled with the horizontal chutes; The horizontal chutes provide sliding guidance for the wedge blocks 102 to ensure the stability of their horizontal movement. The connection between the fixing blocks 17 and the base 12 enhances the structural strength of the buffer assembly 10 and prevents displacement under large impact forces. During high-frequency punching operations, the chute design of the fixing blocks 17 can guide the wedge blocks 102 to move smoothly, ensuring the long-term reliable operation of the buffer assembly 10 and maintaining the stability of the equipment's buffer performance.

[0036] Furthermore, as Figure 2 shown, a clamping groove 18 adapted to the free end of the guide plate 11 is provided at the upper end of the fixing block 17, and the side of the clamping groove 18 is connected to the lower end of the guide groove 16, so that the guide plate 11 can continue the third-stage stroke for the final punching after secondary buffering; The cooperation between the clamping groove 18 and the guide plate 11 realizes three-stage buffering. When the guide plate 11 completes the first two stages of buffering, its free end enters the clamping groove 18, and the final punching is performed through the rigid limit of the clamping groove, ensuring the accuracy of the punching depth. In scenarios where precise control of the punching depth is required, the clamping groove 18 can limit the maximum descending distance of the bearing plate 5 to avoid damage to the aluminum electrode sheet caused by excessive punching. At the same time, the impact force is gradually reduced through multi-stage buffering to ensure the punching quality.

[0037] Specifically, a cooling circuit is provided inside the punching die 3. The inlet end and the outlet end of the cooling circuit are respectively connected to a circulating liquid cooling device, and a valve is installed at the inlet end. As Figure 2 and Figure 3 shown, a control console 22 is also installed on the side of the column of the frame 1. The control knob of the valve is arranged on the control console 22 and is fixedly connected to the shaft end of the control gear 23 on the control console 22. A control rack 24 meshing with the control gear 23 is installed at the bottom of the stopper 103; The cooling circuit cools the punching die 3 through the circulating liquid cooling device to prevent the aluminum substrate from deforming due to high temperature. The control gear 23 and the control rack 24 are linked to automatically adjust the valve opening during the buffering process. When the stopper 103 moves with the movable rod 101, the control rack 24 drives the control gear 23 to rotate, adjusting the flow rate of the cooling circuit. The cooling flow rate is increased before punching to reduce the die temperature, and the flow rate is reduced after punching to save energy, realizing intelligent temperature control and improving punching accuracy and production efficiency.

[0038] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, making equivalent replacements or changes, should be covered by the protection scope of the present invention.
