Description

Technical Field

[0001] This invention relates to the technical field of a battery terminal production device for new energy vehicles, and in particular to a forming mold for battery terminal blanking and forming without flipping. Background Technology

[0002] Battery terminals are crucial components in new energy vehicle batteries. However, with the development of new energy vehicles, the use of new energy batteries has increased dramatically, necessitating high-speed production methods for these components. Therefore, a progressive continuous punching method using a strip material to form battery terminals has been developed. This method typically involves placing the strip material into a progressive die for step-by-step punching to form the battery terminals. However, this method renders the portion of the strip material already punched into battery terminals scrap, resulting in significant material waste and high production costs. Therefore, improvement is urgently needed. Furthermore, after the punching die delivers the finished product, it falls onto the conveyor belt in the material drop channel. However, the distance between the conveyor belt surface and the lower end of the drop channel is considerable, making it prone to flipping during fall. This requires significant manual handling during material collection (requiring the battery terminals to be face up in subsequent production), impacting production efficiency and resulting in a relatively high error rate. Summary of the Invention

[0003] The purpose of this invention is to design a non-flipping molding die for blanking and forming battery terminals in order to overcome the shortcomings of the above-mentioned technologies.

[0004] The present invention discloses a non-tilting molding die for blanking and forming battery terminals. The battery terminal consists of a terminal body, a protrusion formed on the top surface of the terminal body, and a recess formed on the bottom surface of the terminal body. The molding die consists of an upper die and a lower die, including: The preforming station includes at least one first forming group, which includes a protrusion forming structure and a concave forming punch. The protrusion forming structure and the concave forming punch are distributed vertically on the upper and lower dies and are arranged correspondingly to each other for punching and forming protrusions and concave holes of battery terminals. The blanking and forming station is connected to the preforming station, and the blanking and forming station includes a blanking punch and a blanking channel, which are distributed vertically and coaxially. A material discharge conveyor belt is horizontally positioned below the material discharge channel. The distance between the conveying surface of the material discharge conveyor belt and the horizontal plane at the lower end of the material discharge channel is less than the width and length, or diameter, of the pole body.

[0005] According to the above-described non-flipping molding die for blanking and forming battery terminals, the concave hole forming punch includes a first movable block, a forming punch, a first concave template, and a concave template pad. The first concave template and the concave template pad are stacked vertically and installed in the first concave groove of the lower die. The lower end of the forming punch is fixed to the concave template pad, and the forming part of its upper end is located in the first concave hole of the first concave template. The first movable block is placed in the first concave hole of the first concave template and sleeved on the forming part of the forming punch. A first support spring and a first push rod are provided in the lower die. The lower end of the first push rod abuts against the upper end of the first support spring, and the upper end of the first push rod abuts against the bottom surface of the first movable block after passing through the concave template pad. The height of the first movable block is less than the depth of the first concave hole of the first concave template.

[0006] According to the above-described non-flipping molding die for blanking and forming battery terminals, the protrusion forming structure includes a first push rod, a first mounting base, a top pressure rod, two first top pressure columns, and three first springs. The first mounting base is installed in the first mounting groove of the upper die. The protrusion forming structure and the first top pressure columns are both T-shaped structures, so that the protrusion forming structure fits into the T-shaped hole of the first mounting base, and the protrusion forming structure extends from the bottom surface of the upper die. The top pressure rod, the upper ends of the two first top pressure columns, and the three first springs are respectively inserted into corresponding holes in the upper die. The lower end of the top pressure rod abuts against the upper end of the protrusion forming structure. The lower ends of the two first top pressure columns extend out after passing through the first mounting base. A first recess is formed on the inner side of the lower end of the two first top pressure columns. The three first springs abut against the upper ends of the top pressure rod and the two first top pressure columns, respectively. The forming protrusion is coaxially arranged with the protrusion forming hole on the T-shaped hole of the first mounting base.

[0007] According to the above-described battery terminal blanking forming non-flipping forming mold, the pre-forming station also includes at least one second forming group belonging to the previous forming group of the first forming group. The second forming group includes a top pressing structure and a forming die. The top pressing structure and the forming die are distributed vertically and installed on the upper mold and the lower mold respectively.

[0008] According to the above-described non-flipping molding die for blanking and forming of battery terminals, the forming die includes a second movable block and a second concave template. The second concave template is installed in the second concave groove of the lower die. The second movable block is placed in the second concave hole of the second concave template. A second support spring and a second push rod are provided in the lower die. The lower end of the second push rod abuts against the upper end of the second support spring, and the upper end of the second push rod abuts against the bottom surface of the second movable block. The height of the second movable block is less than the depth of the second concave hole of the second concave template.

[0009] According to the above-described forming mold for non-flipping of battery terminal blanks, the top pressing structure includes a second mounting base, a second push rod, and two second top pressing columns. The second mounting base is installed in the mounting groove of the upper mold, and the lower end of the second mounting base extends out of the bottom surface of the upper mold. The second push rod is installed in the mounting hole of the second mounting base, and the top pressing spring installed in the mounting hole of the second mounting base abuts against the top end of the second push rod. The upper ends of the two second top pressing columns pass through the upper mold, and the two second springs in the upper mold abut against the upper ends of each of the second top pressing columns. The lower ends of the two second top pressing columns pass through the second mounting base and extend out, and a second recess is formed on the inner side of the lower ends of the two second top pressing columns.

[0010] According to the above-described forming mold for blanking and forming battery terminals without flipping, the blanking and forming station further includes an upper pad, an upper clamping plate, a stop plate, and an upper stripping plate arranged sequentially from top to bottom. There is a gap between the upper clamping plate and the stop plate. The upper section of the blanking punch is fixed to the upper clamping plate, and the lower section of the blanking punch passes through the punching holes of the stop plate and the upper stripping plate. The punching holes of the stop plate and the upper stripping plate are coaxially arranged with the blanking channel.

[0011] According to the above-described non-flipping molding die for blanking and forming of battery terminals, the blanking and forming station further includes a third spring and a third push rod. The third push rod passes through the blanking punch, the third spring passes through the upper die, and the third spring abuts against the upper end of the third push rod.

[0012] According to the above-described molding die for non-flipping forming of battery terminals, the blanking channel and the battery terminals are preferably square, so the distance between any two opposite corners of the blanking channel is equal to the distance between any two opposite corners of the battery terminals.

[0013] The battery terminal blanking and forming mold described in this invention has the following advantages: 1. It utilizes a progressive continuous conveying and punching method to form the block blanks that need to be shaped, which reduces waste and material waste.

[0014] 2. The distance between the conveying surface of the discharge conveyor belt and the horizontal plane at the lower end of the discharge channel is less than the width and length or diameter of the battery terminal body. This makes it less likely for the battery terminal to flip when it falls onto the discharge conveyor belt, ensuring that the battery terminal always faces upwards when it falls onto the discharge conveyor belt. This eliminates the need for manual material handling and reduces the error rate in material handling. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0027] Example: Example: like Figure 1-10 As shown in this embodiment, a non-flipping molding die for blanking and forming battery terminals is described. The battery terminal 300 consists of a terminal body, a protrusion formed on the top surface of the terminal body, and a recess formed on the bottom surface of the terminal body. The molding die consists of an upper die 1 and a lower die 2, and there are three sets of first forming groups 30, three sets of second forming groups 40, three sets of blanking groups 50, and a translational feeding drive device between the upper die 1 and the lower die 2. The translational feeding drive device is installed on the top surface of the lower die 2. The forming group 40, the first forming group 30 and the blanking module 50 are arranged sequentially from the feeding to the blanking direction. The three first forming groups 30 and the three second forming groups 40 are combined to form the preforming station 3, and the three blanking modules 50 are combined to form the blanking forming station 5. During the blanking process, the translational feeding drive device conveys the block blank 100 to the first forming group 30, the second forming group 40 and the blanking module 50 in a progressive manner, so as to form the battery terminal 300 by blanking through the forming mold.

[0028] In this embodiment, the first forming group 30 includes a protrusion forming structure 31 and a concave hole forming punch 32. The protrusion forming structure 31 and the concave hole forming punch 32 are arranged vertically on the upper die 1 and the lower die 2 and are arranged corresponding to each other to punch and form the protrusions and concave holes of the battery terminal post 300.

[0029] Specifically, the concave hole forming punch 32 includes a first movable block 322, a forming punch 323, a first concave template 321, and a concave template plate 324. The first concave template plate 321 and the concave template plate 324 are stacked vertically and installed in the first concave groove of the lower die 2. The lower end of the forming punch 323 is fixed to the concave template plate 324, and the forming part of its upper end is located in the first concave hole 328 of the first concave template plate 321. The first movable block 322 is placed in the first concave hole 328 of the first concave template plate 321 and sleeved on the forming part of the forming punch 323. A first support spring 326 and a first push rod 325 are provided in the lower die 2, that is, the first support spring 326 is composed of multiple stacked... The first support spring 326 is formed into a butterfly spring and installed in the spring mounting hole of the lower mold 2. A T-shaped post 327 passes through the first support spring 326. The lateral part of the T-shaped post 327 abuts against the upper end of the first support spring 326. Therefore, the lower end of the first push rod 325 abuts against the lateral part of the T-shaped post 327 on the first support spring 326. A plug 200 is installed at the lower end of the spring mounting hole of the lower mold 2 and abuts against the lower end of the first support spring 326 to prevent the first support spring 326 from falling out. The upper end of the first push rod 325 passes through the die pad 324 and abuts against the bottom surface of the first movable block 322. The height of the first movable block 322 is less than the depth of the first die hole 328 of the first die plate 321.

[0030] The protrusion forming structure 31 includes a first push rod 311, a first mounting base 313, a top pressure rod 315, two first top pressure columns 312, and three first springs 317. The first mounting base 313 is installed in the first mounting groove 314 of the upper mold 1. The protrusion forming structure 31 and the first top pressure columns 312 are both T-shaped structures, so that the protrusion forming structure 31 fits into the T-shaped hole of the first mounting base 313, and the protrusion forming structure 31 extends from the bottom surface of the upper mold 1. The top pressure rod 315, the upper ends of the two first top pressure columns 312, and the three first springs 317 are respectively inserted into the first mounting groove 314 of the upper mold 1. In the corresponding hole in the upper mold 1, the upper end of the corresponding hole in the upper mold 1 is blocked by the plug 200 and abuts against the upper end of the first spring 317. The lower end of the top pressure rod 315 abuts against the upper end of the protrusion forming structure 31. The lower ends of the two first top pressure columns 312 extend out after passing through the first mounting base 313. The inner side of the lower end of the two first top pressure columns 312 forms a first recess 316. The three first springs 317 abut against the upper ends of the top pressure rod 315 and the two first top pressure columns 312 respectively. The forming protrusion 323 is coaxially arranged with the protrusion forming hole on the T-shaped hole of the first mounting base 313.

[0031] During the forming process of the first forming assembly 30, the upper mold 1 and the lower mold 2 close together, causing the two first pressing pillars 312 to press against the opposite sides of the upper end surface of the block blank 100. The opposite sides of the upper end of the block blank 100 are then embedded in the first recesses 316 of the two first pressing pillars 312, thereby positioning the block blank 100. At this time, the pressing rod 315 presses against the center of the top surface of the block blank 100, and the lower end of the block blank 100 partially embeds into the first cavity 328 of the first cavity mold 321, causing the first movable block 322 to sink. The first support spring 326 is compressed, and then the forming protrusion 323 protrudes and pushes into the lower end of the block blank 100, thus positioning the lower end of the block blank 100. A concave hole is formed in the part, at which time the upper end face of the block blank 100 is pushed out and protruded, and the protrusion causes the top pressure rod 315 to move upward. The first spring 317, which is located in the middle relative to the top pressure rod 315, is in a compressed state. The lower end of the block blank 100 is partially embedded in the first cavity hole 328 of the first cavity template 321, so that the lower end of the block blank 100 is punched into a large annular step 102 based on the small annular step 101 on the outer periphery of the outer periphery. The formation of this step makes the material on the outer periphery of the block blank 100 thinner, so that the material on the outer periphery of the block blank 100 and the part in the middle that needs to be formed into the battery terminal 300 can be separated from each other after being punched during subsequent blanking and forming. After the mold is opened, the above parts are reset under the action of the corresponding springs.

[0032] Furthermore, the second molding assembly 40 includes a top pressing structure 41 and a molding die 42, which are distributed vertically and installed on the upper die 1 and the lower die 2 respectively.

[0033] The forming die 42 includes a second movable block 422 and a second die template 421. The second die template 421 is installed in the second die groove of the lower die 2. The second movable block 422 is placed in the second die hole 426 of the second die template 421. A second support spring 425 and a second push rod 423 are provided in the lower die 2. That is, an auxiliary block 424 is provided on the upper end of the second support spring 425. Both the auxiliary block and the second support spring 425 are installed in the spring mounting hole of the lower die 2. A plug 200 is installed at the lower end of the spring mounting hole and abuts against the lower end of the second support spring 425. The lower end of the second push rod 423 abuts against the auxiliary block 424 at the upper end of the second support spring 425. The upper end of the second push rod 423 abuts against the bottom surface of the second movable block 422. The height of the second movable block 422 is less than the depth of the second die hole 426 of the second die template 421.

[0034] The top-pressing structure 41 includes a second mounting base 411, a second push rod 412, and two second top-pressing columns 413. The second mounting base 411 is installed in the mounting groove of the upper mold 1, and the lower end of the second mounting base 411 extends out of the bottom surface of the upper mold 1. The second push rod 412 is installed in the mounting hole of the second mounting base 411, and the top-pressing spring 415 installed in the mounting hole of the second mounting base 411 abuts against the top end of the second push rod 412. The two second top-pressing columns 413... The upper end of the column 413 passes through the upper mold 1, and the two second springs 414 in the upper mold 1 abut against the upper ends of each of the second pressing columns 413. The lower ends of the two second pressing columns 413 extend out after passing through the second mounting base 411. A second recess 416 is formed on the inner side of the lower ends of the two second pressing columns 413. The second spring 414 is installed in the hole in the upper mold 1 that is coaxially arranged with the second pressing column 413. A plug 200 is installed at the upper end of the hole and abuts against the upper end of the second spring 414.

[0035] During the forming process of the second forming assembly 40, the upper mold 1 and the lower mold 2 close together, causing the two second pressing pillars 413 to press against the opposite sides of the upper end surface of the block blank 100. The opposite sides of the upper end of the block blank 100 are also submerged in the second recesses 416 of the two second pressing pillars 413, thereby positioning the block blank 100. At this time, the second push rod 412 presses against the center of the top surface of the block blank 100, and the lower end of the block blank 100 is partially submerged in the second recess of the second concave mold plate 421. Within the die hole 426, the second movable block 422 sinks, and the second support spring 425 is compressed, and is in a compressed state with the top pressure spring 415 of the second push rod 412. Since the lower end of the block blank 100 is partially embedded in the second die hole 426 of the second concave template 421, a small annular step 101 is formed on the outer periphery of the lower end of the block blank 100. The formation of the small annular step 101 prepares for the subsequent forming of the large annular step 102. After the mold is opened, the above parts are reset under the action of the corresponding springs.

[0036] In this embodiment, the blanking and forming station 5 is connected to the preforming station 3, and each blanking module 50 of the blanking and forming station 5 includes a blanking punch 51 and a blanking channel 52. The blanking punch 51 and the blanking channel 52 are distributed vertically and coaxially. The blanking and forming station 5 also includes an upper pad 56, an upper clamping plate 57, a stop plate 58, and an upper ejector plate 59 arranged from top to bottom. There is a gap between the upper clamping plate 57 and the stop plate 58. The upper section of the blanking punch 51 is fixed to the upper clamping plate 57 by means of screws on the bottom surface of the upper clamping plate 57. Bolt 61 fixes the limiting block 53, which is at least partially placed in the locking groove 511 to fix the blanking punch 51 on the upper clamping plate 57. The top surface of the stop plate 58 is provided with a relief groove 62 to avoid the head of the bolt 61 used to fix the limiting block 53, so that the distance between the clamping plate and the stop plate 58 can be reduced when the mold is closed. After the distance is reduced, the head of the bolt 61 is inserted into the relief groove 62. The lower section of the blanking punch 51 passes through the punching holes of the stop plate 58 and the upper ejector plate 59. The punching holes of the stop plate 58 and the upper ejector plate 59 are coaxially arranged with the blanking channel 52.

[0037] Preferably, each blanking module 50 of the blanking forming station 5 further includes a third spring 55 and a third push rod 54. The third push rod 54 passes through the blanking punch 51, and the third spring 55 passes through the upper die 1. The third spring 55 abuts against the upper end of the third push rod 54.

[0038] Preferably, the upper mold 1 is also provided with a push spring and a T-shaped push rod. The lateral part of the T-shaped push rod is limited to the top surface of the upper pad 56, and its longitudinal part passes through the upper pad 56 and the upper clamping plate 57 in sequence and then abuts against the top surface of the stop plate 58. A limiting plate is fixed to the side of the clamping plate, and a stroke groove is formed on the inner side of the limiting plate. The peripheral part of the stop plate 58 is located in the stroke groove. When the limiting plate abuts against the lower limit surface of the stroke groove, the distance between the stop plate 58 and the clamping plate increases. When the limiting plate moves away from the lower limit surface of the stroke groove, the distance 78 between the stop plate 58 and the clamping plate decreases. Thus, after the blanking and punching are completed, the stop plate 58 is reset by the action of the push spring and the T-shaped push rod, and the distance between the stop plate 58 and the clamping plate increases. Generally, there are multiple limiting plates, push springs and T-shaped push rods to make the mold structure run stably.

[0039] Preferably, the material discharge channel 52 and the battery terminal 300 are square, so the distance between any two opposite corners of the material discharge channel is equal to the distance between any two opposite corners of the battery terminal 300, thereby locking the discharged battery terminal 300 to prevent it from falling off instantly, so that the battery terminal 300 is stacked in the material discharge channel 52 after being formed and output one by one from the lower port of the material discharge channel 52.

[0040] When each blanking die group 50 of the blanking forming station 5 described above is punching, after the upper die 1 and the lower die 2 are closed, the block blank 100 is clamped between the lower die 2 and the upper ejector plate 59. The lower end of the third push rod 54 abuts against the top surface of the block blank 100 and moves upward, causing the third spring 55 to be in a compressed state. At the same time, the upper die 1 continues to move downward, driving the upper pad plate 56 and the upper clamping plate 57 to move downward, so that the distance between the upper clamping plate 57 and the stop plate 58 becomes smaller, prompting the blanking process to proceed smoothly. The upper end of the blanking punch 51 and the blanking channel 52 punch and blank the middle part of the block blank, thereby forming the battery terminal 300 and entering the blanking channel 52. After the punching is completed, the upper die 1 and the lower die 2 open the die, the third push rod 54 resets, and under the action of the fourth spring and the fourth push rod in the upper die 1, the distance between the upper clamping plate 57 and the stop plate 58 increases and resets, and the lower limit surface supports the position of the upper ejector plate 59.

[0041] In this embodiment, the discharge conveyor belt 6 is horizontally positioned below the discharge channel 52. The distance between the conveying surface 60 of the discharge conveyor belt 6 and the horizontal plane at the lower end of the discharge channel 52 is less than the width and length, or diameter, of the electrode body. The discharge conveyor belt 6 is a belt conveyor, which makes it difficult for the electrode falling onto the conveying surface 60 of the belt conveyor to flip over. Because the battery electrodes 300 in the discharge channel 52 are stacked and locked in the discharge channel, and when a battery electrode 300 is punched and enters the upper end of the discharge channel 52, the battery electrode 300 at the lower end of the discharge channel 52 is squeezed out and falls onto the belt conveyor. At the same time, the lowest battery electrode 300 in the discharge channel 52 moves down to the lower end of the discharge channel 52.

[0042] In this embodiment, the translational feeding drive device includes two moving strips 8 arranged along the feeding direction of the forming mold, and a drive mechanism 400 that drives the two moving strips 8 to move synchronously in a straight line along the feeding direction of the forming mold while moving relatively closer or further away. The two moving strips 8 are both mounted on the drive part of the drive mechanism 400. The gripper structure 9 on one side of the positioning area for positioning the block blank in the second forming group, the first forming group, and the blanking module is mounted on one moving strip 8, and the gripper structure 9 on the other side is mounted on the other moving strip 8. That is, the gripper seats 91 of all the gripper structures 9 on opposite sides are fixedly mounted on the two moving strips 8. The two moving strips 8 are located on both sides of the width direction of the module 201 of the lower mold 2. The inner end clamping groove 90 of each gripper structure 9 is a triangular structure.

[0043] Furthermore, the drive mechanism 400 includes a first motor 402, a second motor 409, a first lead screw 403 arranged along the feeding direction, two first crossbeams 404 and two first linear guides 405, and a second lead screw 406, a second crossbeam 407 and two second linear guides 408 arranged along the width direction of the battery terminal 500 forming mold. The first lead screw 403 and the second lead screw 406 are arranged in a cross shape, with the first lead screw 403 located above the second lead screw 406. The two threaded sections on the second lead screw 406 have opposite helical directions, and ball bearing sleeves 410 are screwed onto each of the two threaded sections. Crossbeams 404 are respectively mounted on each ball sleeve 410. Each first linear guide 405 is fixedly mounted on two first crossbeams 404. Two moving bars 8 are respectively fixedly mounted on the sliders of each first linear guide 405. A second crossbeam 407 is fixedly mounted on the ball sleeve 410 of the first lead screw 403. Two second linear guides 408 are fixedly mounted on the second crossbeam 407. The sliders on each second linear guide 408 are respectively fixedly connected to the ends of the two moving bars 8. The shaft of the first motor 402 is connected to the end of the first lead screw 403 via a transmission mechanism. The shaft of the second motor 409 is connected via a transmission mechanism. The end of the second lead screw 406 is connected to a transmission mechanism, which is generally a chain drive. All fixed installations are secured with bolts. The first motor 402 controls the first lead screw 403 to rotate forward or backward in a forward / reverse drive manner. This causes the first lead screw 403 to drive its ball sleeve 410 to reciprocate linearly along the feeding direction, causing the two moving bars 8 to reciprocate linearly along the feeding direction. The second motor 409 controls the second lead screw 406 to rotate forward or backward in a forward / reverse drive manner, causing the two ball sleeves 410 on the second lead screw 406 to reciprocate linearly relative to each other, causing the two moving bars 8 to move closer together or... The process moves away from each other, further enabling the clamping structures 9 on opposite sides of each positioning area to clamp the block blank 100 at the corresponding position and then transport it to the rear positioning area. That is, the block blank 100 in the positioning area of ​​the second forming group is transported to the positioning area of ​​the first forming group, and the block blank 100 originally located in the positioning area of ​​the first forming group is transported to the positioning area of ​​the blanking module. After one transport is completed, the clamping structures 9 on the two moving strips 8 move away from each other and move in a straight line in the opposite direction of feeding, and then return to the original position. Thus, the battery terminal 500 forming mold performs progressive translation feeding in a cycle according to the above steps during punching.

[0044] Preferably, both first crossbeams 404 are fixed on the frame 401, and the first lead screw 403 and the second lead screw 406 are rotatably mounted on the frame 401 through bearing seats.

[0045] During blanking, the PLC controller controls the second motor 409 to move, causing the gripper structures 9 of the two moving strips 8 to close together and clamp the block blank 100 in the corresponding positioning area. The block blank 100 is clamped in two opposing clamping slots 90, with the outer peripheral wall of the block blank 100 abutting against the inner wall of the clamping slot 90. At this time, the pressing member 94 on the gripper structure 9 in each positioning area abuts against the block blank 100 and is displaced, causing the sensing rod on the pressing member 94 to abut against the contact sensor. At the same time, the return spring 93 and the extension spring 95 are both in a compressed state, and the translation gripper 910 is also in a retracted state. At this time, the contact sensor transmits the contact signal to the PLC controller, and the PLC controller controls the first motor 402 to move, causing the gripper structures 9 of the two moving strips 8 to translate along the feeding direction, so as to clamp the block blank 100 in the positioning area of ​​the second forming group. The blank 100 is conveyed to the positioning area of ​​the first forming group, and the block blank 100 originally located in the positioning area of ​​the first forming group is conveyed to the positioning area of ​​the blanking module. When the first motor 402 controlled by the PLC controller runs for a preset time, the first motor 402 stops working. Then the PLC controller controls the stamping machine to work, causing the upper die 1 and the lower die 2 to close. Thus, each of the top pressing rods of the upper die 1 presses against the corresponding block blank 100, so that the block blank 100 in each positioning area is punched to form the corresponding features. Thus, the second forming group forms a small annular step on the lower outer periphery of the block blank, the first forming group punches the small annular step on the lower outer periphery of the block blank to form a large annular step, and the blanking module punches and blanks the middle part of the block blank to separate the large annular step from the middle part, thereby forming the battery terminal and blanking it into the blanking channel. At the same time, the PLC controller controls the first motor 402 and the second motor 409 to move, thereby causing the gripper structures 9 on the two moving bars 8 to move away from each other and move in a straight line in the opposite direction of feeding, and then return to their original positions in preparation for the next feeding and punching.
