Description

Technical Field

[0001] This invention relates to the field of stamping equipment technology, specifically to a stamping device and a stamping method for battery steel casings. Background Technology

[0002] Stamping equipment is a core piece of equipment used in industrial production for processing metal sheets. It applies pressure to metal through molds to achieve forming, separation and other processes, and is widely used in manufacturing industries such as automobiles, home appliances and electronics. As an important component of new energy batteries, battery steel shells protect battery modules and promote safe battery use. Most existing battery steel shells are formed by stamping using stamping equipment.

[0003] Chinese patent CN202421352687.0 discloses a stamping device for processing steel shells of new energy batteries. After stamping, as the stamping module rises, the stamped steel shell can be taken out of the mold, which effectively solves the problem that it is inconvenient to remove the steel shell from the mold once it is stuck in the mold, and helps to improve work efficiency.

[0004] However, the above technical solutions still have certain drawbacks. For example, although they can demold the stamped steel shell, manual removal is still required after demolding, which is time-consuming and labor-intensive. Furthermore, after demolding the steel plate, the U-shaped bracket needs to be manually pried open to reset it. This increases the number of operation steps, which greatly increases the workload of workers when stamping steel plates in batches and also affects the stamping efficiency. In addition, when using existing stamping equipment, workers complete both loading and unloading operations below the stamping machine. This means that if there is a malfunction in the stamping equipment or worker misoperation, the stamping equipment may directly injure the workers below, thus posing a certain safety hazard. Summary of the Invention

[0017] A stamping method for a battery steel casing, using the aforementioned stamping device.

[0018] Compared with the prior art, the present invention provides a stamping device and a stamping method for battery steel casings, which have the following advantages:

[0019] 1. In this invention, during the stamping of a steel plate, the steel plate is placed on a conveyor plate with one end in contact with the inside of a right-angle plate for positioning. Then, a drive mechanism moves the conveyor plate below the stamping mechanism, which stamps the steel plate. After stamping, the drive mechanism returns the conveyor plate and the stamped steel plate to their original positions. During this process, the movement of the conveyor plate drives the transmission assembly. When the transmission assembly reaches the position of the unloading rack, the unloading rack drives the transmission assembly to rotate, which in turn drives the reciprocating screw to rotate. The reciprocating screw then drives the right-angle plate to move, pushing the stamped steel plate from the conveyor plate towards the unloading port. As the conveyor plate moves, the right-angle plate further pushes the stamped steel plate into the unloading port. At this point, the stamped steel plate falls through the unloading port, completing the unloading process. Since the conveyor plate has not yet returned to its original position, the unloading rack continues to drive the transmission assembly after the right-angle plate has unloaded the stamped steel plate. The transmission assembly then drives the reciprocating screw to rotate continuously. The reciprocating screw then drives the right-angle plate, after unloading, back to its original position. Once the right-angle plate reaches its original position, the conveyor plate also reaches its original position, and the drive mechanism stops operating. The user can then perform the stamping action again, thus achieving automatic unloading of the stamped steel plate. This avoids the time-consuming, labor-intensive, and potentially dangerous problem of manual unloading. Furthermore, the right-angle plate's return to its original position after unloading facilitates the subsequent positioning of other steel plates, improving ease of use.

[0020] 2. In this invention, when the drive mechanism drives the conveyor plate to move toward the stamping mechanism, the pressure plate and the lowering component move along with the conveyor plate. After the lowering component moves to the position of the fixed rack, the fixed rack can drive the lowering component to operate. The operation of the lowering component drives the pressure plate to move down. After the pressure plate moves down, it presses down and fixes the steel plate on the conveyor plate, thereby fixing the steel plate on the conveyor plate, thus improving the stability of the subsequent stamping of the steel plate. When the drive component drives the conveyor plate back to its original position and passes the fixed rack, the fixed rack drives the pressure plate back to its original position through the lowering component, thereby releasing the fixation of the steel plate and facilitating the subsequent unloading of the steel plate.

[0021] 3. In this invention, when the driving mechanism drives the conveyor plate and steel plate below the stamping mechanism, the stamping mechanism stamps the steel plate on the conveyor plate. During stamping, since the demolding springs are located below the driving mechanism and the conveyor plate is connected to the driving mechanism, the driving mechanism moves down synchronously as the stamping mechanism moves the steel plate down, squeezing the demolding springs. After the stamping mechanism completes the stamping, the driving mechanism, conveyor plate, and steel plate return to their original positions under the action of the demolding springs, thus completing the demolding of the steel plate. After demolding, the conveyor plate can be directly returned to its original position by the driving mechanism without any further operations, thereby improving ease of use.

[0022] 4. The present invention, through the arrangement of the feeding port, unloading mechanism, conveying plate and driving mechanism, ensures that the worker is not under the stamping mechanism during feeding and unloading, thereby completely avoiding the problem of physical injury to the worker caused by the stamping mechanism due to malfunction or misoperation after stamping, greatly improving the safety of equipment use and thus providing safety protection for the worker.

[0036] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a stamping device and a stamping method for battery steel casing.

[0038] Example 1: Please refer to Figures 1-12 A stamping device includes a main body 1, a stamping mechanism 3 and a sponge roller for applying lubricating oil to a steel plate on the main body 1, a base 8 on the main body 1, a drive mechanism 2 and a conveyor plate 4 on the base 8, a feeding port 9 on one side of the main body 1, during feeding, the steel plate can pass through the feeding port 9 and be placed on the conveyor plate 4, the drive mechanism 2 and the conveyor plate 4 are distributed on both sides of the main body 1, a demolding spring 5 is arranged horizontally below the drive mechanism 2, the demolding spring 5 is used to demold the stamped steel plate, the conveyor plate 4 is used to support the steel plate, during stamping, the drive mechanism 2 can drive the conveyor plate 4 to move below the stamping mechanism 3;

[0039] The conveyor plate 4 is provided with a fixing mechanism 6 and a unloading mechanism 7. The fixing mechanism 6 includes a fixing rack 61, a pressure plate 63 and a downward moving component 64. The fixing rack 61 is used to drive the downward moving component 64 to operate. When the downward moving component 64 operates, it can drive the pressure plate 63 to move downward.

[0040] The unloading mechanism 7 includes a right-angle plate 71, a reciprocating screw 72, a transmission assembly 73, an unloading rack 738, and an unloading port 74. The unloading rack 738 is used to drive the transmission assembly 73 to operate, and the transmission assembly 73 is used to drive the reciprocating screw 72 to operate. When the reciprocating screw 72 operates, the right-angle plate 71 can push the stamped steel plate to the unloading port 74.

[0041] In use, the steel plate to be stamped is placed on the conveyor plate 4 through the feeding port 9, with one end of the steel plate in contact with the right-angle plate 71. Then, the drive mechanism 2 drives the conveyor plate 4 to move towards the stamping mechanism 3. The movement of the conveyor plate 4 moves the steel plate. When the conveyor plate 4 moves to the position of the fixed rack 61, the fixed rack 61 drives the downward moving component 64 to operate. The downward moving component 64 drives the pressure plate 63 to move downward. After the pressure plate 63 moves downward, it presses down and fixes the steel plate on the conveyor plate 4, thus pressing and fixing the steel plate onto the conveyor plate 4. Then, the conveyor plate 4 moves the steel plate through the sponge roller, which applies lubricating oil to the bottom surface of the steel plate. After that, the drive mechanism 2 drives the conveyor plate 4 to move towards the stamping mechanism 3. Below the stamping mechanism 3, the stamping mechanism 3 stamps the steel plate on the conveyor plate 4. During this process, the stamping mechanism 3 squeezes the conveyor plate 4 and the steel plate. Since the demolding spring 5 is distributed below the drive mechanism 2 and the conveyor plate 4 is connected to the drive mechanism 2, when the stamping mechanism 3 squeezes the steel plate downward, the drive mechanism 2 also moves downward synchronously and squeezes the demolding spring 5. After the stamping mechanism 3 completes the stamping, the conveyor plate 4 and the steel plate return to their original positions under the action of the demolding spring 5. At this time, the demolding of the steel plate is completed. Then, the drive mechanism 2 drives the conveyor plate 4 and the stamped steel plate back to their original positions. During this process, when the downward moving component 64 passes the fixed rack 61 again, the fixed rack 61 drives... The downward component 64 rotates in reverse, thereby driving the pressure plate 63 to move upward. At this time, the pressure plate 63 releases its fixation to the steel plate. Then, when the conveyor plate 4 moves to the position of the unloading rack 738, the unloading rack 738 drives the transmission component 73 to rotate. The rotation of the transmission component 73 drives the reciprocating screw 72 to rotate. The rotation of the reciprocating screw 72 drives the right-angle plate 71 to move towards the feeding port 9. The movement of the right-angle plate 71 pushes the stamped steel plate on the conveyor plate 4 towards the unloading port 74. Then, the steel plate is pushed off the conveyor plate 4 by the right-angle plate 71 and falls through the unloading port 74, thus completing the unloading. Afterward, because the conveyor plate 4 has not yet returned to its original position, after the right-angle plate 71 completes the unloading of the steel plate, the conveyor plate 4 will still... As the machine continues to move, the unloading rack 738 continues to drive the transmission assembly 73 and the reciprocating screw 72 to operate continuously. The reciprocating screw 72 drives the right-angle plate 71, which has completed unloading, back to its original position. After the right-angle plate 71 reaches its original position, the conveyor plate 4 also reaches its original position. Then, the steel plate is placed for the next stamping, thus achieving the effect of automatically unloading the stamped steel plate, avoiding the time-consuming and labor-intensive problem of manual unloading. It can also automatically fix the steel plate, and automatically demold the steel plate after stamping. No additional operation is required after demolding. Finally, the worker will not work under the stamping equipment, thus greatly improving the safety of the worker.

[0042] Example 2: See Figures 1-12Unlike Embodiment 1 described above, the driving mechanism 2 includes a driving screw 21, which is rotatably connected to the inner side of the base 51, with both ends of the driving screw 21 extending out of the base 51. A driving block 22 is threaded onto the driving screw 21, and a limiting slide rail 23 is slidably connected to one side of the driving block 22. The limiting slide rail 23 is distributed at the upper and lower ends of the driving block 22 and is fixedly connected to the inner side of the base 51. A driving motor 24 is fixedly connected to one end of the driving screw 21 and is fixedly connected to the base 51. The lowering assembly 64 includes a mounting hole 641, a limiting hole 642, and a gear hole 643. The mounting hole 641 is formed on the conveyor plate 4, and a self-locking screw 646 is rotatably connected within the mounting hole 641. A movable block 648 is threaded onto the rod 646. The movable block 648 is fixedly connected to the pressure plate 63. A limiting hole 642 is opened on the conveyor plate 4 and is distributed on both sides of the conveyor plate 4. A limiting rod 644 is fixedly connected to the inner side of the limiting hole 642. The pressure plate 63 is slidably connected to the limiting rod 644. A fixed gear 645 is provided inside the gear hole 643. One end of the self-locking screw 646 away from the mounting hole 641 passes through the mounting hole 641 and is fixedly connected to the fixed gear 645 inside the gear hole 643. A horizontal plate 647 is fixedly connected to the outer side of the fixed rack 61. The horizontal plate 647 is fixedly connected to the main body 1 of the equipment. When the fixed gear 645 moves to the fixed rack 61, the fixed rack 61 can mesh with the fixed gear 645.

[0043] In use, the drive motor 24 drives the drive screw 21 to rotate. The rotation of the drive screw 21 causes the drive block 22 to move along the limit slide rail 23. The movement of the drive block 22 causes the conveyor plate 4 to move. The movement of the conveyor plate 4 causes the steel plate, the self-locking screw 646, the fixed gear 645, and the pressure plate 63 to move towards the stamping mechanism 3. After the fixed gear 645 moves to the position of the fixed rack 61, the fixed gear 645 meshes with the fixed rack 61. As the conveyor plate 4 moves, the fixed rack 61 drives the fixed gear 645 to rotate. The rotation of the fixed gear 645 drives the self-locking screw 646 to rotate. The rotation of the self-locking screw 646 drives the moving block 648 to move. The movement of the moving block 648 causes the pressure plate 63 to move down along the limit rod 644. Then the pressure plate 63 presses down and fixes the steel plate on the conveyor plate 4. After that, the fixed gear 645 moves along the conveyor plate... When the movement of plate 4 separates from the fixed rack 61, the pressure plate 63, in cooperation with the self-locking screw 646, can maintain the downward pressure and fixation of the steel plate. After the stamping is completed, the drive motor 24 drives the drive screw 21 to rotate in the opposite direction, thereby driving the conveyor plate 4 to return to its position through the drive block 22. At this time, the fixed gear 645 passes through the fixed rack 61 again, and the fixed rack 61 drives the fixed gear 645 to rotate in the opposite direction. The fixed gear 645 drives the pressure plate 63 to move upward through the self-locking screw 646. At this time, the pressure plate 63 releases the fixation of the steel plate, thereby achieving the effect of automatic fixation and release of the steel plate. While improving the stamping effect, it also facilitates the subsequent unloading of the steel plate. Furthermore, the setting of the horizontal plate 647 can enclose both sides of the main body 1 of the equipment, thereby protecting the stamping equipment and preventing outsiders from contacting the stamping mechanism 3.

[0044] Example 3, see Figures 1-12 Unlike the second embodiment described above, the stamping mechanism 3 includes a hydraulic cylinder 31 and a lower die 32. The hydraulic cylinder 31 is located on the top surface of the equipment body 1. The output shaft of the hydraulic cylinder 31 passes through the equipment body 1 and is fixedly connected to a stamping head 33. An upper die 34 is located at the bottom of the stamping head 33. Upper slide rails 35 are slidably connected to both sides of the stamping head 33 and are fixedly connected to the equipment body 1. The lower die 32 is fixedly connected to the base platform 8. The top surface of the lower die 32 is at the same level as the top surface of the conveyor plate 4. Rubber rollers 36 are located on both sides of the lower die 32. A base 51 is fixedly connected to the top of the demolding spring 5. A lower slide rail 52 is slidably connected to the outer side of the base 51. The lower slide rail 52 is distributed at both ends of the base 51 and is fixedly connected to the equipment body 1. A bearing plate 53 is fixedly connected to the bottom of the demolding spring 5 and is fixedly connected to the equipment body 1. The bearing plate 53 is distributed below the base 51.

[0045] During stamping, the hydraulic cylinder 31 drives the stamping head 33 to move down along the upper slide rail 35. The downward movement of the stamping head 33 causes the upper mold 34 to move down. After the upper mold 34 moves down, it contacts the steel plate on the conveyor plate 4 and causes the steel plate to move down. The downward movement of the steel plate causes the conveyor plate 4 and the base 51 to move down. The downward movement of the base 51 compresses the demolding spring 5. Then, with the cooperation of the hydraulic cylinder 31, the upper mold 34 and the lower mold 32, the steel plate is demolded. After stamping is completed, the hydraulic cylinder 31 drives the stamping head 33 and the upper mold 34 to return to their original positions. At this time, the pressure on the demolding spring 5 gradually decreases, and the demolding spring 5 gradually returns to its original state. During the process of the demolding spring 5 returning to its original state, the demolding spring 5 lifts the base 51 and the steel plate, thereby pushing the stamped steel plate out of the lower mold 32, thus completing the demolding of the steel plate.

[0046] Example 4, see Figures 1-12 Unlike Embodiment 3 described above, the transmission assembly 73 includes a rectangular hole 731 and a driving bevel gear 732. The rectangular hole 731 is formed on the conveyor plate 4. The reciprocating screw 72 is rotatably connected to the inside of the rectangular hole 731, and both ends of the reciprocating screw 72 extend out of the rectangular hole 731. A slider 733 is slidably connected to the inside of the rectangular hole 731. The slider 733 is slidably connected to the reciprocating screw 72 and is fixedly connected to the bottom of the right-angle plate 71. The driving bevel gear 732 is fixedly connected to one end of the reciprocating screw 72. A driven bevel gear 734 meshes with the outside of the driving bevel gear 732. The outside of the driven bevel gear 734 is fixedly connected to... There is a rotating shaft 735, and a housing 736 is provided on the outside of the rotating shaft 735. The housing 736 is fixedly connected to one side of the conveyor plate 4. The driving bevel gear 732 and the driven bevel gear 734 are both distributed inside the housing 736. The rotating shaft 735 is installed on the outside of the housing 736 through a bearing seat. The end of the rotating shaft 735 away from the driven bevel gear 734 passes through the housing 736 and is fixedly connected to a ratchet structure 739. A discharge gear 737 is provided on the outside of the ratchet structure 739. The discharge gear 737 meshes with a discharge rack 738. The discharge rack 738 is fixedly connected to the main body 1 of the equipment. The discharge rack 738 and the discharge gear 737 are kept on the same horizontal plane.

[0047] After the steel plate is stamped, the conveyor plate 4 is driven to return to its original position by the drive mechanism 2. During this process, the unloading gear 737 contacts the unloading rack 738. As the conveyor plate 4 returns to its original position, the unloading rack 738 drives the unloading gear 737 to rotate. The rotation of the unloading gear 737 drives the ratchet structure 739 to rotate. The rotation of the ratchet structure 739 drives the rotating shaft 735 to rotate. The rotation of the rotating shaft 735 drives the driven bevel gear 734 to rotate. The rotation of the driven bevel gear 734 drives the driving bevel gear 732 to rotate. The rotation of the driving bevel gear 732 drives the reciprocating screw 72 to rotate. The rotation of the reciprocating screw 72 drives the slider 733 to move along the rectangular hole 731. The movement of the slider 733 drives the right-angle plate 71 to move. The movement of the right-angle plate 71 moves the conveyor plate 4 onto the conveyor plate. The stamped steel plate is pushed towards the unloading port 74. Then, under the push of the right-angle plate 71, the steel plate falls from the conveyor plate 4 to the unloading port 74 and is discharged through the unloading port 74. Since the conveyor plate 4 has not yet returned to its original position, it will continue to move after the right-angle plate 71 finishes unloading the steel plate. At this time, the unloading rack 738 continues to drive the transmission assembly 73 and the reciprocating screw 72 to continue to operate. The reciprocating screw 72 drives the right-angle plate 71, which has completed unloading, back to its original position. After the right-angle plate 71 returns to its original position, the conveyor plate 4 also returns to its original position, thus achieving the effect of automatic unloading. Furthermore, the ratchet structure 739 ensures that the right-angle plate 71 will not operate when the conveyor plate 4 is feeding unstamped steel plates.
