Description

Technical Field

[0001] This application belongs to the technical field of busbar production equipment and specifically relates to a busbar punching and shearing machine. Background Art

[0002] The busbar punching and shearing machine is an automated equipment specially used for processing busbars. It integrates functions such as automatic feeding, automatic positioning, automatic clamping, automatic punching, automatic shearing, automatic embossing and automatic splicing, which greatly improves the production efficiency of busbars.

[0003] At present, the molds of common busbar punching and shearing machines all adopt a double-row type, which leads to a larger body structure of the busbar punching and shearing machine, which is relatively bulky as a whole and has high manufacturing and installation costs. In addition, the clamping force of the busbar by the clamping device of the busbar punching and shearing machine cannot be adjusted, which makes it easy for clamping marks to appear on the busbar, causing the busbar to be easily clamped and easily tipped over, making it impossible to automatically produce the busbar, thereby affecting the production efficiency of the busbar. Utility Model Content

[0004] The present application provides a busbar punching and shearing machine to reduce the overall volume of the busbar punching and shearing machine, reduce the production cost of the busbar punching and shearing machine, and improve the production efficiency of the busbar.

[0005] The technical solutions adopted in this application are:

[0006] A busbar punching and shearing machine comprises a frame, a punching and shearing assembly arranged on the frame, and a clamping assembly arranged on the frame, the punching and shearing assembly having a plurality of punching dies, which are arranged in sequence and in a single row along the width direction of the frame, two groups of clamping assemblies are provided and are respectively located on both sides of the punching and shearing assembly, each group of clamping assemblies comprises a clamping frame, a transmission structure arranged on the clamping frame, a servo motor arranged on the clamping frame, and a first clamping jaw and a second clamping jaw arranged on the clamping frame, the first clamping jaw and the second clamping jaw are connected to the transmission structure, and the servo motor is used to drive the transmission structure to move so that the transmission structure drives the first clamping jaw and the second clamping jaw to move toward or away from each other.

[0007] By adopting the above technical solution, since the multiple punching dies are arranged in sequence along the width direction of the frame and in a single row, compared with the multiple punching dies arranged in multiple rows in the prior art, the overall volume of the busbar punching and shearing machine is reduced, and the production cost of the busbar punching and shearing machine is reduced; since the clamping assembly has a servo motor and a transmission structure, the clamping assembly drives the first clamping jaw and the second clamping jaw through the servo motor, so that the clamping force of the first clamping jaw and the second clamping jaw on the busbar can be easily adjusted. On the one hand, it can avoid the occurrence of clamping marks and clamping injuries on the busbar to ensure the production quality of the busbar. On the other hand, it can avoid the situation where the first clamping jaw and the second clamping jaw have a large clamping force on the busbar, which makes the busbar easy to tip over, so as to improve the production efficiency of the busbar.

[0008] Optionally, the punching and shearing assembly includes a mounting frame, an upper mold frame and a lower mold frame arranged on the mounting frame, a driving structure for driving the upper mold frame and the upper mold frame to move along the width direction of the frame, and a lower pressure piece. The upper mold frame and the lower mold frame are arranged opposite to each other and a space for the busbar to pass through is formed therebetween. A plurality of punching dies are arranged on the upper mold frame, and the lower mold frame is provided with die holes corresponding to the punching dies. The lower pressure piece can drive the corresponding punching die head downward so that the punching die head and the upper mold frame slide relative to each other and extend into the corresponding die hole.

[0009] By adopting the above technical solution, after the position where the busbar needs to be punched moves to the punching and shearing assembly, the driving structure drives the upper mold frame and the lower mold frame, and then the corresponding punching die head moves to the position where the busbar needs to be punched. At this time, the punching die head to be worked is opposite to the lower pressing piece, and then the lower pressing piece is started, so that the lower pressing piece drives the punching die head, and the punching die head passes through the busbar and extends into the die hole to complete the punching of the busbar.

[0010] Optionally, a connecting block is provided between the upper mold frame and the lower mold frame, so that the upper mold frame and the lower mold frame are fixedly connected via the connecting block, and the driving structure is connected to the lower mold frame.

[0011] By adopting the above technical solution, since a connecting block is provided between the upper mold frame and the lower mold frame, the upper mold frame and the lower mold frame are fixedly connected together through the connecting block, so that the upper mold frame and the lower mold frame can move synchronously, thereby simplifying the structure of the drive structure and reducing the production cost of the busbar punching and shearing machine.

[0012] Optionally, the driving structure includes a driving rod, a driving block threadedly connected to the driving rod, and a servo drive motor for driving the driving rod to rotate, and the driving block is connected to the lower mold frame.

[0013] By adopting the above technical solution, when adjusting the punching die head, the servo drive motor is started, and then the servo drive motor drives the drive rod, and the drive rod and the drive block rotate relative to each other, so that the drive block moves along the axial direction of the drive rod, and the drive block drives the lower mold frame to move, so as to achieve the adjustment of the position of the punching die head.

[0014] Optionally, the punching and shearing assembly also includes a punching die head and an embossing upper die head provided on the upper mold frame, and the punching die head and the embossing upper die head are respectively located on both sides of the punching die head, and the lower mold frame is provided with an embossing lower die head opposite to the embossing upper die head and a punching hole opposite to the punching die head.

[0015] By adopting the above technical solution, since the punching die head and the embossing upper die head are respectively located on both sides of the punching die head, the structure of the punching and shearing assembly is made more compact, thereby further reducing the overall volume of the busbar punching and shearing machine. At the same time, the busbar punching and shearing machine can also realize embossing and shearing functions, thereby increasing the flexibility of the busbar punching and shearing machine.

[0016] Optionally, a sealing plate and an elastic member acting on the sealing plate are slidably connected in the punching hole. When the punching die moves into the punching hole under the action of the pressing member, the sealing plate moves downward under the action of the punching die head, and the elastic member is deformed and applies an upward elastic force to the sealing plate.

[0017] By adopting the above technical solution, when the busbar is punched, the lower pressure part drives the punching die head, and then the punching die head moves downward, so that the punching die head punches the busbar and moves the sealing plate downward, so that the sealing plate squeezes the elastic part, and the elastic part is deformed, so that the punching die head can move into the punching hole. After the busbar is punched, the elastic part recovers its deformation, so that the sealing plate moves to the opening of the punching hole under the action of the elastic part, so as to achieve the blocking of the punching hole opening, thereby avoiding the situation that the end of the busbar hits the opening of the punching hole during the transportation of the busbar and affects the transportation of the busbar.

[0018] Optionally, the punching die includes a die body and a reset guide member provided on the upper mold frame and acting on the die body. When the die body moves downward under the action of the lower pressure member, the reset guide member is in a deformed state and applies an upward elastic force to the die body.

[0019] By adopting the above technical solution, when the lower pressure piece applies downward pressure to the punching die, the die body moves downward under the action of the lower pressure piece. At this time, the reset guide is compressed and applies an upward elastic force to the die body, and then after the downward pressure applied by the lower pressure piece to the die body disappears, the die body can move upward under the action of the reset guide to separate from the busbar, so that the clamping assembly can continue to transport the busbar. At the same time, the reset guide can also guide the movement of the die body to increase the movement stability of the die body.

[0020] Optionally, the reset guide includes a guide tube sleeved on the die body, a first elastic reset portion provided on the top of the guide tube and acting on the die body, and a second elastic reset portion provided on the upper mold frame and acting on the guide tube, and the guide tube is passed through the upper mold frame.

[0021] By adopting the above technical solution, when the lower pressure piece drives the punching die downward, the lower pressure piece acts on the die body, thereby causing the die body to apply downward pressure to the first elastic reset part, the first elastic reset piece applies a downward elastic force to the guide tube, and the guide tube applies downward pressure to the second elastic reset part, thereby causing the guide tube and the die body to move downward at the same time to complete the punching of the busbar; however, through the provision of the guide tube, the guiding effect of the upper mold frame on the die body can be increased, thereby increasing the punching effect of the die body on the busbar.

[0022] Optionally, the transmission structure includes a transmission shaft and a first transmission block and a second transmission block threadedly connected to the transmission shaft, and the servo motor is used to drive the transmission shaft to rotate. When the transmission shaft rotates, the first transmission block and the second transmission block move in a direction approaching or moving away from each other, the first clamp is connected to the first transmission block, and the second clamp is connected to the second transmission block.

[0023] By adopting the above technical solution, when clamping the busbar, the servo motor is started to drive the transmission shaft to rotate, and then the transmission shaft and the first transmission block and the second transmission block are rotated relative to each other, so that the first transmission block and the second transmission block move in a direction approaching each other, so that the first clamp and the second clamp clamp the busbar. Through the arrangement of the transmission shaft, the first transmission block and the second transmission block, the accuracy of the movement position of the first clamp and the second clamp can be increased to ensure the clamping effect of the busbar and at the same time increase the production efficiency of the busbar.

[0024] Optionally, the clamping frame is provided with slide rails located on both sides of the transmission shaft, and the first clamping jaw and the second clamping jaw are both provided with sliders that slide with the slide rails.

[0025] By adopting the above technical solution, when the first jaw and the second jaw move, the first jaw drives its own slider to move, and the second jaw drives its own slider to move, so that the slider and the slide rail slide relative to each other, so that the sliding cooperation between the slider and the slide rail guides the movement of the first jaw and the second jaw, thereby increasing the movement stability of the first jaw and the second jaw.

[0026] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0027] 1. The busbar punching and shearing machine in the present application includes a frame, a punching and shearing assembly arranged on the frame, and a clamping assembly arranged on the frame. The punching and shearing assembly has a plurality of punching dies, which are arranged in sequence and in a single row along the width direction of the frame. The clamping assembly is provided with two groups and is respectively located on both sides of the punching and shearing assembly. Each group of clamping assemblies includes a clamping frame, a transmission structure arranged on the clamping frame, a servo motor arranged on the clamping frame, and a first clamping jaw and a second clamping jaw arranged on the clamping frame. The first clamping jaw and the second clamping jaw are connected to the transmission structure. The servo motor is used to drive the transmission structure to move so that the transmission structure drives the first clamping jaw and the second clamping jaw to move in a direction close to or away from each other. Since the plurality of punching dies are arranged along the width of the frame, the first clamping jaw and the second clamping jaw are respectively arranged in a direction close to or away from each other. The directions are arranged in sequence and in a single row, and then compared with the multi-row arrangement of multiple punching die heads in the prior art, the overall volume of the busbar punching and shearing machine is reduced, and the production cost of the busbar punching and shearing machine is reduced; because the clamping assembly has a servo motor and a transmission structure, the clamping assembly drives the first clamping jaw and the second clamping jaw through the servo motor, so that the clamping force of the first clamping jaw and the second clamping jaw on the busbar can be easily adjusted. On the one hand, it can avoid the occurrence of clamping marks and clamping injuries on the busbar to ensure the production quality of the busbar, and on the other hand, it can avoid the situation where the first clamping jaw and the second clamping jaw have a large clamping force on the busbar, which causes the busbar to easily tip over, so as to improve the production efficiency of the busbar.

[0028] 2. The punching and shearing assembly in the present application includes an installation frame, an upper mold frame and a lower mold frame arranged on the installation frame, a driving structure for driving the upper mold frame and the lower mold frame to move along the width direction of the frame, and a lower pressure piece. The upper mold frame and the lower mold frame are arranged opposite to each other and a space for the busbar to pass through is formed between the two. A plurality of punching dies are arranged on the upper mold frame, and the lower mold frame is provided with die holes corresponding to the punching dies. The lower pressure piece can drive the corresponding die head downward so that the punching die head and the upper mold frame slide relative to each other and extend into the corresponding die hole. After the position where the busbar needs to be punched moves to the punching and shearing assembly, the driving structure drives the upper mold frame and the lower mold frame, and then the corresponding punching die head moves to the position where the busbar needs to be punched. At this time, the punching die head to be worked is opposite to the lower pressure piece, and then the lower pressure piece is started, so that the lower pressure piece drives the punching die head, and the punching die head passes through the busbar and extends into the die hole to complete the punching of the busbar.

[0029] 3. A connecting block is provided between the upper mold frame and the lower mold frame in the present application, so that the upper mold frame and the lower mold frame are fixedly connected through the connecting block, and the driving structure is connected to the lower mold frame, and then the upper mold frame and the lower mold frame are fixedly connected together through the connecting block, so that the upper mold frame and the lower mold frame can move synchronously, so as to simplify the structure of the driving structure and reduce the production cost of the busbar punching and shearing machine.

[0044] Reference Figures 1 to 6, discloses a busbar punching and shearing machine, which includes a frame 1, a punching and shearing assembly 2 arranged on the frame 1, and a clamping assembly 3 arranged on the frame 1, the punching and shearing assembly 2 has a plurality of punching dies 21, and the plurality of punching dies 21 are arranged in sequence and in a single row along the width direction of the frame 1, the clamping assembly 3 is provided with two groups and is respectively located on both sides of the punching and shearing assembly 2, each group of the clamping assembly 3 includes a clamping frame 31, a transmission structure 32 arranged on the clamping frame 31, a servo motor 33 arranged on the clamping frame 31, and a first clamping jaw 34 and a second clamping jaw 35 provided on the clamping frame 31, the first clamping jaw 34 and the second clamping jaw 35 are connected to the transmission structure 32, and the servo motor 33 is used to drive the transmission structure 32 to move, so that the transmission structure 32 drives the first clamping jaw 34 and the second clamping jaw 35 to move in a direction close to or away from each other.

[0045] Since the multiple punching dies 21 are arranged in sequence along the width direction of the frame 1 and in a single row, compared with the multiple rows of multiple punching dies 21 in the prior art, the overall volume of the busbar punching and shearing machine is reduced, and the production cost of the busbar punching and shearing machine is reduced; since the clamping assembly 3 has a servo motor 33 and a transmission structure 32, the clamping assembly 3 drives the first clamping jaw 34 and the second clamping jaw 35 through the servo motor 33, so that the clamping force of the first clamping jaw 34 and the second clamping jaw 35 on the busbar can be easily adjusted. On the one hand, it can avoid the occurrence of clamping marks and clamping injuries on the busbar to ensure the production quality of the busbar. On the other hand, it can avoid the situation where the first clamping jaw 34 and the second clamping jaw 35 have a large clamping force on the busbar, which causes the busbar to easily tip over, so as to improve the production efficiency of the busbar.

[0046] In a preferred embodiment, referring to Figure 3 and Figure 4 The punching and shearing assembly 2 includes a mounting frame 22, an upper mold frame 23 and a lower mold frame 24 arranged on the mounting frame 22, a driving structure 25 for driving the upper mold frame 23 and the upper mold frame 23 to move along the width direction of the frame 1, and a lower pressing member 26. The upper mold frame 23 and the lower mold frame 24 are arranged opposite to each other and a space for the busbar to pass through is formed between the two. A plurality of punching dies 21 are arranged on the upper mold frame 23, and the lower mold frame 24 is provided with die holes corresponding to the punching dies 21. The lower pressing member 26 can drive the corresponding punching die head 21 downward so that the punching die head 21 slides relative to the upper mold frame 23 and extends into the corresponding die hole.

[0047] Specifically, after the position where the busbar needs to be punched moves to the punching and shearing assembly 2, the driving structure 25 drives the upper mold frame 23 and the lower mold frame 24, and then the corresponding punching die 21 moves to the position where the busbar needs to be punched. At this time, the punching die 21 to be worked is opposite to the lower pressure piece 26, and then the lower pressure piece 26 is started, so that the lower pressure piece 26 drives the punching die 21, and the punching die 21 passes through the busbar and extends into the die hole to complete the punching of the busbar.

[0048] The present application does not make any specific limitation on the structure of the lower pressing member 26. Preferably, refer to Figure 3 and Figure 4 The pressing member 26 is a cylinder, the cylinder body of which is fixedly connected to the mounting frame 22, and the piston rod of the cylinder can act on the opposite punching die 21 to apply downward pressure to the opposite punching die 21. In other embodiments, the pressing member 26 can also be a hydraulic cylinder, an electric push rod, or other structures that can drive the punching die 21 to move downward.

[0049] The present application does not make any specific limitation on the connection method between the upper mold frame 23 and the lower mold frame 24. Preferably, refer to Figure 3 and Figure 4 A connecting block 231 is provided between the upper mold frame 23 and the lower mold frame 24 so that the upper mold frame 23 and the lower mold frame 24 are fixedly connected through the connecting block 231 , and the driving structure 25 is connected to the lower mold frame 24 .

[0050] Since a connecting block 231 is provided between the upper mold frame 23 and the lower mold frame 24, the upper mold frame 23 and the lower mold frame 24 are fixedly connected together through the connecting block 231, so that the upper mold frame 23 and the lower mold frame 24 can move synchronously, thereby simplifying the structure of the driving structure 25 and reducing the production cost of the busbar punching and shearing machine.

[0051] In other embodiments, the upper mold frame 23 and the lower mold frame 24 may not have a direct connection relationship, and the two are only arranged relative to each other, but the driving structure 25 needs to be connected to the upper mold frame 23 and the lower mold frame 24 to drive the upper mold and the lower mold frame 24 to move in a direction parallel to the width of the frame 1.

[0052] The present application does not make any specific limitation on the structure of the driving structure 25. Preferably, refer to Figure 3 and Figure 4 The driving structure 25 includes a driving rod 251 , a driving block 252 threadedly connected to the driving rod 251 , and a servo driving motor 253 for driving the driving rod 251 to rotate. The driving block 252 is connected to the lower mold frame 24 .

[0053] It can be understood that the servo drive motor 253 is fixedly connected to the rack 1 or the mounting frame 22 , and the drive rod 251 is rotationally connected to the mounting frame 22 or the rack 1 .

[0054] When adjusting the punching die 21, the servo drive motor 253 is started, which in turn drives the drive rod 251. The drive rod 251 and the drive block 252 rotate relative to each other, thereby causing the drive block 252 to move along the axial direction of the drive rod 251. The drive block 252 drives the lower mold frame 24 to move, thereby adjusting the position of the punching die 21. At the same time, the accuracy of the drive structure 25 in driving the upper mold frame 23 and the lower mold frame 24 can be increased, thereby ensuring the production quality of the busbar.

[0055] In other embodiments, the driving structure 25 can also be a hydraulic cylinder, a pneumatic cylinder, an electric push cylinder, or other structures provided on the mounting frame 22 or the frame 1 that can drive the upper mold frame 23 and the lower mold frame 24 to move along the width direction of the frame 1.

[0056] In a preferred embodiment, referring to Figure 3 and Figure 4 The punching and shearing assembly 2 also includes a punching die head 27 and an embossing upper die head 28 provided on the upper mold frame 23. The punching die head 27 and the embossing upper die head 28 are respectively located on both sides of the punching die head 21. The lower mold frame 24 is provided with an embossing lower die head 281 opposite to the embossing upper die head 28 and a punching hole opposite to the punching die head 27.

[0057] Specifically, since the punching die 27 and the embossing upper die 28 are respectively located on both sides of the punching die 21, the structure of the punching and shearing assembly 2 is made more compact, thereby further reducing the overall volume of the busbar punching and shearing machine. At the same time, the busbar punching and shearing machine can also realize embossing and shearing functions to increase the flexibility of the busbar punching and shearing machine.

[0058] Further, refer to Figure 3 and Figure 4 A sealing plate 242 and an elastic member acting on the sealing plate 242 are slidably connected in the punching hole 241. When the punching die 27 moves into the punching hole 241 under the action of the pressing member 26, the sealing plate 242 moves downward under the action of the punching die 27, and the elastic member is deformed and applies an upward elastic force to the sealing plate 242.

[0059] It is understandable that when the blocking plate 242 is not under downward pressure, the top end surface of the blocking plate 242 is flush with the top end surface of the lower mold frame 24 .

[0060] Specifically, when the busbar is punched, the pressing member 26 drives the punching die 27, and then the punching die 27 moves downward, so that the punching die 27 punches the busbar and moves the sealing plate 242 downward, so that the sealing plate 242 squeezes the elastic member, and the elastic member is deformed, so that the punching die 27 can move into the punching hole 241. After the busbar is punched, the elastic member recovers its deformation, so that the sealing plate 242 moves to the orifice of the punching hole 241 under the action of the elastic member, so as to achieve the blocking of the orifice of the punching hole 241, and avoid the situation in which the end of the busbar hits the orifice of the punching hole 241 during the transportation of the busbar and affects the transportation of the busbar.

[0061] The present application does not specifically limit the structure of the elastic member. Preferably, the elastic member is a spring to ensure the elastic driving effect on the blocking plate 242. In other embodiments, the elastic member can also be an elastic sheet, an elastic column, or other structures that can apply elastic force to the blocking plate 242.

[0062] In a preferred embodiment, referring to Figure 5 The punching die 21 includes a die body 211 and a reset guide 212 provided on the upper mold frame 23 and acting on the die body 211. When the die body 211 moves downward under the action of the lower pressure member 26, the reset guide 212 is in a deformed state and applies an upward elastic force to the die body 211.

[0063] Specifically, when the lower pressure piece 26 applies downward pressure to the punching die 21, the die body 211 moves downward under the action of the lower pressure piece 26. At this time, the reset guide 212 is compressed and applies an upward elastic force to the die body 211, and then the downward pressure applied by the lower pressure piece 26 to the die body 211 disappears. The die body 211 can move upward under the action of the reset guide 212 to separate from the busbar, so that the clamping assembly 3 can continue to transport the busbar. At the same time, the reset guide can also guide the movement of the die body 211 to increase the movement stability of the die body 211.

[0064] The present application does not make any specific limitation on the structure of the reset guide 212. Preferably, refer to Figure 5 The reset guide 212 includes a guide tube 213 sleeved on the die body 211, a first elastic reset portion 214 provided on the top of the guide tube 213 and acting on the die body 211, and a second elastic reset portion 215 provided on the upper mold frame 23 and acting on the guide tube 213. The guide tube 213 is passed through the upper mold frame 23.

[0065] Specifically, when the lower pressure piece 26 drives the punching die 21 downward, the lower pressure piece 26 acts on the die body 211, thereby causing the die body 211 to apply downward pressure to the first elastic reset portion 214, and the first elastic reset piece applies a downward elastic force to the guide tube 213, and the guide tube 213 applies downward pressure to the second elastic reset portion 215, so that the guide tube 213 and the die body 211 move downward at the same time to complete the punching of the busbar; however, through the provision of the guide tube 213, the guiding effect of the upper mold frame 23 on the die body 211 can be increased, so as to increase the punching effect of the die body 211 on the busbar.
