Generally, three loading channels 12 and loading rods 11 are provided, and the loading rods 11 are fixedly installed on the upper... Mold 100, the upper port of each feeding channel 12 is connected to three guides on the belt feeder, so that the block blanks continuously conveyed by the belt feeder enter the feeding channel 12 for storage, so that multiple block blanks 300 are stored in a stacked manner in each feeding channel 12. When the upper mold 100 and the lower mold 200 are closed, the feeding rod 11 is inserted into the feeding channel 12 to discharge the material, causing the block blank 300 located at the lower port of the feeding channel 12 to be pressed out and fall onto the placement table 13. When the upper mold 100 and the lower mold 200 are opened, the feeding rod 11 is moved out of the feeding channel 12, and one block blank 300 is added under the action of continuous conveying by the belt feeder, in preparation for the next mold closing and feeding, and then the above steps are repeated for continuous feeding.

[0034] The leveling station 3 includes at least one leveling module, which includes a leveling punch 31, a leveling positioning area, and a first ejector pin 32. The leveling punch 31 is located above the leveling positioning area and is coaxially arranged with it. The first ejector pin 32 is movably inserted into the upper mold 100 of the battery terminal forming mold. A first spring 33 is also inserted into the upper mold 100 of the battery terminal forming mold. The first spring 33 abuts against the upper end of the first ejector pin 32. The lower end of the first ejector pin 32 passes through the leveling punch 31. When the upper die 100 and the lower die 200 are closed for punching, the lower end of the leveling punch 31 protrudes from the bottom surface of the upper die 100. The first ejector pin 32 presses against the top surface of the block blank 300 to position it. Thus, the lower end of the leveling punch 31 applies punching force to the top surface of the block blank 300. Under the support of the top surface of the lower die 200, the top and bottom surfaces of the block blank 300 are made flat.

[0035] The first step and center hole forming station 4 includes at least one first forming module. The first forming module includes a first punch 41, a second punch 42, a step and center hole forming positioning area 45, and a second ejector pin 43. The first punch 41 is embedded in the upper mold 100 of the battery terminal forming mold. The bottom surface of the first punch 41 has an annular protrusion 411 for forming the first step. The second punch 42 is embedded in the first punch 41, and the forming end 421 of the second punch 42 extends beyond the height of the annular protrusion 411, so that the forming end of the second punch 42... 421 is at least partially exposed; the first punch 41 and the second punch 42 are both located above the step and center hole forming positioning area 45 and are coaxially arranged with each other; the second push rod 43 is movably inserted into the upper mold 100 of the battery terminal forming mold, and the upper mold 100 of the battery terminal forming mold is also provided with a second spring 44, the second spring 44 abuts against the upper end of the second push rod, and the lower end of the second push rod 43 passes through the first punch 41, the second punch 42 is located at the center of the first punch 41, and the second push rod 43 is offset from the center of the first punch 41. When the upper die 100 and the lower die 200 are closed for punching, the forming end 421 of the second punch 42 and the annular protrusion 411 of the first punch 41 both protrude from the bottom surface of the upper die 100. The second ejector pin 43 presses against the top surface of the block blank 300 to position it. Then the forming end 421 and the annular protrusion 411 punch the block blank 300 to form the center hole and the first step on the block blank 300.

[0036] The second step forming station 5 includes at least one second forming module. The second forming module includes a step forming punch 51, a step forming positioning area 54, and a third push rod 52. The step forming punch 51 is located above the step forming positioning area 54 and is coaxially arranged with each other. A forming punch ring 511 is formed on the bottom surface of the step forming punch 51. The third push rod 52 is movably inserted into the upper mold 100 of the battery terminal forming mold. A third spring 53 is also inserted into the upper mold 100 of the battery terminal forming mold. The third spring 53 abuts against the upper end of the third push rod 52, and the lower end of the third push rod 52 passes through the step forming punch 51. When the upper die 100 and the lower die 200 are closed for punching, the forming ring 511 of the step forming punch 51 protrudes from the bottom surface of the upper die 100, and the third ejector pin 52 is inserted into the center hole of the block blank 300 to position it. Then the forming ring 511 of the step forming punch 51 punches the block blank 300 so that the second step located below the first step is formed on the block blank 300.

[0037] The engraving station 6 includes at least one engraving module, which includes an engraving punch 61, an engraving positioning area 64, and a central push rod 62. The engraving punch 61 is located above the engraving positioning area 64 and is coaxially arranged with the engraving punch 61. The bottom surface of the engraving punch 61 forms a raised character 611, which is offset from the center of the engraving punch 61. The central push rod 62 is movably inserted into the upper mold 100 of the battery terminal forming mold. A central spring 63 is also inserted into the upper mold 100 of the battery terminal forming mold. The central spring 63 abuts against the upper end of the central push rod 62, and the lower end of the central push rod 62 passes through the engraving punch 61. When the upper die 100 and the lower die 200 are closed for punching, the lower end of the engraving punch 61 protrudes from the bottom surface of the upper die 100, and the central ejector pin 62 is inserted into the central hole of the block blank 300 to position it. Then, the character 611 of the engraving punch 61 punches the top surface of the block blank 300 so that the character 611 mark is formed on the top surface of the block blank 300.

[0038] The blanking station 7 includes at least one blanking module, which includes a blanking punch 71, a blanking positioning area 82, a fourth ejector pin 72, and a blanking channel 81 located below the blanking positioning area 82. The blanking punch 71 is located above the blanking positioning area 82 and is coaxially arranged with each other. A blanking ring 711 is formed on the bottom surface of the blanking punch 71. The blanking channel 81 is formed in the lower mold 200 of the battery terminal forming mold. The fourth ejector pin 72 is movably inserted into the upper mold 100 of the battery terminal forming mold. A fourth spring 73 is also inserted into the upper mold 100 of the battery terminal forming mold. The fourth spring 73 abuts against the upper end of the fourth ejector pin 72, and the lower end of the fourth ejector pin 72 passes through the blanking punch 71.

[0039] Preferably, the blanking module further includes an upper pad 74, a clamping plate 75, a stop plate 76, and a stripping plate 77 arranged sequentially from top to bottom. The upper pad 74 and clamping plate 75 are both fixed to the upper mold 100 of the battery terminal forming mold. A gap 78 exists between the stop plate 76 and the clamping plate 75. The stop plate 76 and the stripping plate 77 are fixedly arranged together. A top-pressure spring and a return T-rod are inserted into the upper mold 100 of the battery terminal forming mold. The longitudinal part of the return T-rod passes through the upper pad 74 and clamping plate 75 and abuts against the top surface of the stop plate 76. Its transverse part remains within the mounting hole of the upper mold 100 of the battery terminal forming mold. The two ends of the top-pressure spring abut against the transverse part of the return T-rod and the upper end plug of the mounting hole, respectively. The upper end of the blanking punch 71 passes through the clamping plate 75, and its lower section passes through the stop plate 76 and the clamping plate 75. The outer periphery of its middle section forms a locking groove 70. The bottom surface of the clamping plate 75 is fixed with a limiting block 79 by bolts. The limiting block 79 is at least partially placed in the locking groove 70 to fix the blanking punch 71 on the clamping plate. The upper end of the blanking channel 81 is fixed with a lower die 80. The die hole 801 of the lower die 80 is coaxially arranged with the blanking channel 81. The top surface of the stop plate 76 is provided with a clearance groove 601 to avoid the head of the bolt 600 used to fix the limiting block. This makes the distance between the clamping plate 75 and the stop plate 76 smaller when the mold is closed. After the distance 78 becomes smaller, the head of the bolt 600 is inserted into the clearance groove 601.

[0040] Therefore, during blanking and punching, the upper die 100 and the lower die 200 close, the stripper plate 77 abuts against the top surface of the block blank 300, the fourth ejector pin 72 is inserted into the already formed center hole on the block blank 300, and then the upper die 100 continues to move downward, causing the distance 78 between the stop plate 76 and the clamping plate 75 to decrease, causing the blanking punch 71 to move downward and its lower end to extend, so that the lower end of the blanking punch 71 and the die hole 801 cooperate to punch the block blank 300 with the first step, the second step and the center hole, thereby forming the battery terminal 500 finished product and falling into the blanking channel 81. After punching, an annular scrap is formed on the top surface of the lower die 200.

[0041] Based on the upper mold having a push spring 702 and a T-shaped push rod 703, the lateral portion of the T-shaped push rod is limited to the top surface of the upper pad 74, and its longitudinal portion passes through the upper pad 74 and the clamping plate 75 in sequence before contacting the top surface of the stop plate 76. A limiting plate 700 is fixed to the side of the clamping plate 75, and a stroke groove 701 is formed on the inner side of the limiting plate 700. The peripheral portion of the stop plate 76 is located in the stroke groove 701. When the limiting plate 700 contacts the lower limiting surface 704 of the stroke groove 701, the stop plate 76... When the gap 78 between the clamping plates 75 increases, and the lower limit surface 704 of the limiting plate 700 and the stroke groove 701 moves away from each other, the gap 78 between the stop plate 76 and the clamping plates 75 decreases. Thus, after blanking and punching are completed, the stop plate 76 is reset by the action of the push spring 702 and the T-shaped push rod 703, and the gap 78 between the stop plate 76 and the clamping plates 75 increases. Generally, there are multiple limiting plates, push springs and T-shaped push rods to ensure stable operation of the mold structure.

[0042] In this embodiment, a material preparation station 2 located in front of the leveling station 3 is also included. The material preparation station 2 includes at least one material preparation module. The material preparation module includes a pressure rod 21, a pressure spring 22, and a material preparation area 23. The pressure rod 21 is located above the material preparation area 23 and is coaxially arranged with each other. The pressure rod 21 and the pressure spring 22 are both inserted into the upper mold 100 of the battery terminal forming mold. The pressure spring 22 abuts against the upper end of the pressure rod 21, and the lower end of the pressure rod 21 passes through the upper mold 100 of the battery terminal forming mold and extends to the outside.

The two moving strips 8 are both installed on the drive part of the drive mechanism 400. All the gripper structures 9 on one side of the positioning area of ​​the loading station 1, leveling station 3, first step and center hole forming station 4, second step forming station 5, engraving station 6 and unloading station 7 are installed on one moving strip 8, and all the gripper structures 9 on the other side are installed on the other moving strip 8. That is, the gripper seats 91 of all the gripper structures 9 on opposite sides are fixedly installed on the two moving strips 8 respectively. The two moving strips 8 are located on both sides of the width direction of the module 201 of the lower mold 200.

[0049] Further, 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 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. The two first crossbeams 404 are respectively mounted on each ball bearing sleeve 410. Linear guide rails 405 are fixedly mounted on two first crossbeams 404, and two moving bars 8 are fixedly mounted on the sliders of each first linear guide rail 405.

The transmission mechanism is generally a chain drive. All fixed installations are secured with bolts. Motor 402 controls the first lead screw 403 to rotate forward or reverse in a forward and reverse drive manner, thereby driving its ball sleeve 410 to perform linear reciprocating motion along the feeding direction, causing the two moving strips 8 to perform linear reciprocating motion along the feeding direction. The second motor 409 controls the second lead screw 406 to rotate forward or reverse in a forward and reverse drive manner, thereby driving the two ball sleeves 410 on the second lead screw 406 to perform relative reciprocating linear motion, causing the two moving strips 8 to move closer or further apart. This further enables the clamping structures 9 located on opposite sides of each positioning area to close together to clamp the block blank 300 at the corresponding position, and then transport it to the rear positioning area, that is: the block blank 300 in the preparation area 23... The blank 300 is conveyed to the leveling and positioning area. The block blank 300 originally located in the leveling and positioning area is conveyed to the step and center hole forming positioning area 45. The block blank 300 originally located in the step and center hole forming positioning area 45 is conveyed to the step forming positioning area 54. The block blank 300 originally located in the step forming positioning area 54 is conveyed to the lettering positioning area 64. The block blank 300 originally located in the lettering positioning area 64 is conveyed to the blanking positioning area 82. After one conveying is completed, the gripper structure 9 on the two moving bars 8 moves away from each other and moves in a straight line in the opposite direction of feeding, and then returns to its original position. Thus, the battery terminal forming die performs progressive translation feeding in a cycle according to the above steps during punching.

[0050] 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.

[0051] During punching, the PLC controller controls the second motor 409 to move, causing the gripper structures 9 of the two moving bars 8 to close together and clamp the block blank 300 in the corresponding positioning area. The block blank 300 is clamped in two opposing clamping slots 90, with the outer peripheral wall of the block blank 300 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 300 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 controls the... The device controls the first motor 402 to move, which in turn causes the gripper structure 9 of the two moving bars 8 to move along the feeding direction, so as to transport the block blank 300 in the preparation area 23 to the leveling and positioning area, transport the block blank 300 originally located in the leveling and positioning area to the step and center hole forming positioning area 45, transport the block blank 300 originally located in the step and center hole forming positioning area 45 to the step forming positioning area 54, transport the block blank 300 originally located in the step forming positioning area 54 to the engraving positioning area 64, transport the block blank 300 originally located in the engraving positioning area 64 to the unloading positioning area 82, and push the waste material in the unloading positioning area 82 away from the unloading positioning area 82. When the PLC controller controls the first motor 402 to move, the device moves the gripper structure 9 of the two moving bars 8 to move along the feeding direction, so as to transport the block blank 300 in the preparation area 23 to the leveling and positioning area, transport the block blank 300 originally located in the leveling and positioning area to the step and center hole forming positioning area 45, transport the block blank 300 originally located in the step and center hole forming positioning area 45 to the step forming positioning area 54, transport the block blank 300 originally located in the step forming positioning area 54 to the engraving positioning area 64, transport the block blank 300 originally located in the engraving positioning area 64 to the unloading positioning area 82, and push the waste material in the unloading positioning area 82 away from the unloading positioning area 82. After the machine 402 has been running for a preset time, the first motor 402 stops working. Then, the PLC controller controls the stamping machine to work, causing the upper die 100 and the lower die 200 to close. This causes the ejector pins of the upper die 100 to press against the top surface of the corresponding block blank 300 and into the center hole of the block blank 300. At this time, the punches in each positioning area punch the corresponding block blank 300, thus achieving the center positioning and adjustment of the block blank 300 in the preparation area 23, leveling the block blank 300 in the leveling positioning area, and punching to form the first step and center hole on the block blank 300 in the step forming positioning area 45. The block blank 300 in the step forming positioning area 54... The upper blank 300 has a second step in the punching process. The block blank 300 in the engraving positioning area 64 has the character 611 marked in the punching process. The block blank 300 in the blanking positioning area 82 is punched to form a battery terminal 500 with a first step, a second step and a center hole. It falls into the blanking channel 81. At the same time, the PLC controller controls the first motor 402 and the second motor 409 to move, thereby causing the gripper structure 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 the original position. At this time, the top pressing part 94 and the translation gripper 910 return to the original position under the restoring force of the return spring 93 and the extension spring 95, in preparation for the next feeding and punching.
