Description

Technical Field

[0001] The present invention relates to the technical field of stamping equipment, and in particular to a stamping device and a stamping method for a battery steel shell. Background Art

[0002] Stamping equipment is the core equipment used for metal sheet processing in industrial production. It applies pressure to the metal through molds to achieve forming, separation and other processes. It is widely used in manufacturing fields such as automobiles, home appliances, and electronics. Battery steel shells are important components of new energy batteries. Installing the battery module in the battery steel shell can protect it, which is conducive to the safe use of the battery. Most of the existing battery steel shells are stamped by stamping equipment.

[0003] Chinese patent CN202421352687.0 discloses a stamping device for processing steel shells for new energy batteries. After stamping, as the stamping module rises, the stamped steel shell can be taken out of the mold, effectively solving the problem of the steel shell being inconvenient to remove from the mold once it is stuck in the mold, helping to improve work efficiency. However, the above technical solution still has certain defects. For example, although it can demould the stamped steel shell, manual material removal is still required after demoulding, which is time-consuming and labor-intensive. In addition, after the steel plate is demoulded, the above technical solution still needs to manually open the handle to reset the U-shaped bracket. This method increases the operation steps, resulting in a significant increase in the workload of workers when stamping steel plates in batches, and also affects the stamping efficiency of the steel plates. At the same time, when the existing stamping equipment is in use, whether it is loading or retrieving materials, the workers are all under the stamping machine.

[0014] A method for punching a battery steel shell uses the above-mentioned punching device.

[0015] Compared with the prior art, the present invention provides a stamping device and a stamping method for a battery steel shell, which have the following beneficial effects: 1. In the present invention, when stamping the steel plate, the steel plate is placed on the conveying plate, and one end of the steel plate is in contact with the inside of the right-angle plate to position the steel plate. The conveying plate is then driven by the driving mechanism to move to the bottom of the stamping mechanism, and then the steel plate on the conveying plate is stamped by the stamping mechanism. After the stamping is completed, the conveying plate and the stamped steel plate are driven back to their original positions by the driving mechanism. In this process, the conveying plate drives the transmission assembly to move when it moves. After the transmission assembly moves to the position of the unloading rack, the unloading rack drives the transmission assembly to operate, and the operation of the transmission assembly drives the reciprocating screw to rotate, and the rotation of the reciprocating screw drives the right-angle plate to move. The right-angle plate moves to push the stamped steel plate on the conveying plate to the unloading port. Then, as the conveying plate moves, the right-angle plate pushes the stamped steel plate to the unloading port. At this time, the stamped steel plate falls through the discharge port, thus completing the unloading. Afterwards, since the conveying plate has not yet reached its original position, after the right-angle plate unloads the stamped steel plate, the unloading rack is still driving the transmission assembly to operate. At this time, the transmission assembly drives the reciprocating screw to rotate continuously. At this time, the reciprocating screw drives the right-angle plate after unloading to return to its original position. After the right-angle plate reaches its original position, the conveying plate also reaches its original position. At this time, the driving mechanism is no longer running, and the user can then perform the stamping action of the steel plate again, thereby achieving the effect of automatically unloading the stamped steel plate, thereby avoiding the time-consuming and labor-intensive manual unloading and the problem of certain safety hazards. After the right-angle plate completes unloading, it can also return to its original position, which is convenient for subsequent positioning of other steel plates, thereby improving ease of use.

[0016] 2. In the present invention, when the driving mechanism drives the conveying plate to move toward the stamping mechanism, the pressure plate and the downward moving assembly move with the conveying plate. After the downward moving assembly moves to the position of the fixed rack, the fixed rack can drive the downward moving assembly to operate, and the operation of the downward moving assembly drives the pressure plate to move downward. After the pressure plate moves downward, it presses down and fixes the steel plate on the conveying plate, thereby fixing the steel plate on the conveying plate, thereby improving the stability of the subsequent stamping of the steel plate, and when the driving assembly drives the conveying plate to return to its original position and passes through the fixed rack, the fixed rack drives the pressure plate to return to its original position through the downward moving assembly, thereby releasing the fixation of the steel plate, thereby facilitating the subsequent unloading of the steel plate.

[0017] 3. The present invention uses a demoulding spring. When the driving mechanism drives the conveying plate and the steel plate to be under the stamping mechanism, the steel plate on the conveying plate is stamped by the stamping mechanism. During stamping, since the demoulding springs are respectively under the driving mechanism and the conveying plate is connected to the driving mechanism, when the stamping mechanism drives the steel plate to move downward, the driving mechanism also moves downward synchronously and squeezes the demoulding spring. After the stamping mechanism completes the stamping, the driving mechanism, the conveying plate and the steel plate return to their original positions under the action of the demoulding spring. At this time, the demoulding of the steel plate is completed, and after demoulding, the conveying plate can be directly returned to its original position by the driving mechanism without the need for other operations, thereby improving the convenience of use.

[0018] 4. The present invention, through the arrangement of the feeding port, unloading mechanism, conveying plate and driving mechanism, ensures that workers will not be under the stamping mechanism during feeding and unloading, thereby completely avoiding the problem of the stamping mechanism causing physical harm to workers due to failure or misoperation of the stamping mechanism during stamping or after stamping is completed, greatly improving the safety of the equipment during use, and thus providing safety protection for the workers.

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] As introduced in the background technology, there are deficiencies in the existing technology. In order to solve the above technical problems, this application proposes a stamping device and a stamping method for battery steel shells.

[0023] Example 1: Please refer to Figures 1-12 A stamping device includes an equipment body 1, on which a stamping mechanism 3 and a sponge roller for applying lubricating oil to a steel plate are provided. A base 8 is provided on the equipment body 1, on which a driving mechanism 2 and a conveying plate 4 are provided. A feeding port 9 is also provided on one side of the equipment body 1. When loading, the steel plate can pass through the feeding port 9 and be placed on the conveying plate 4. The driving mechanism 2 and the conveying plate 4 are distributed on both sides of the equipment body 1. A demoulding spring 5 is provided in a horizontal array below the driving mechanism 2. The demoulding spring 5 is used to demould the steel plate after stamping. The conveying plate 4 is used to carry the steel plate. When stamping, the driving mechanism 2 can drive the conveying plate 4 to move below the stamping mechanism 3. The conveying plate 4 is provided with a fixing mechanism 6 and a discharge mechanism 7. The fixing mechanism 6 includes a fixed rack 61, a pressure plate 63 and a lowering assembly 64. The fixed rack 61 is used to drive the lowering assembly 64 to operate. When the lowering assembly 64 operates, it can drive the pressure plate 63 to move downward. The unloading mechanism 7 includes a right-angle plate 71, a reciprocating screw 72, a transmission assembly 73, a unloading rack 738 and a 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 is operating, the right-angle plate 71 can push the stamped steel plate to the unloading port 74.

[0024] During use, the steel plate to be punched is placed on the conveying plate 4 through the feeding port 9, and one end of the steel plate is in contact with the right-angle plate 71. The conveying plate 4 is then driven by the driving mechanism 2 to move toward the punching mechanism 3. The movement of the conveying plate 4 drives the steel plate to move. When the conveying plate 4 moves to the position of the fixed rack 61, the fixed rack 61 drives the lowering assembly 64 to operate, and the lowering assembly 64 drives the pressing plate 63 to move downward. After the pressing plate 63 moves downward, it presses down and fixes the steel plate on the conveying plate 4, thereby pressing and fixing the steel plate on the conveying plate 4. After that, the conveying plate 4 drives the steel plate to pass through the sponge roller, and the sponge roller rubs lubricating oil on the bottom surface of the steel plate. After that, the driving mechanism 2 drives the conveying plate 4 to move to The punching mechanism 3 is below the punching mechanism 3, and then the punching mechanism 3 punches the steel plate on the conveying plate 4. During this process, the punching mechanism 3 squeezes the conveying plate 4 and the steel plate. Since the demoulding spring 5 is distributed below the driving mechanism 2, and the conveying plate 4 is connected to the driving mechanism 2, when the punching mechanism 3 squeezes the steel plate and moves downward, the driving mechanism 2 also moves downward synchronously and squeezes the demoulding spring 5. After the punching mechanism 3 completes the punching, the conveying plate 4 and the steel plate return to their original positions under the action of the demoulding spring 5. At this time, the demoulding of the steel plate is completed, and then the conveying plate 4 and the stamped steel plate are driven by the driving mechanism 2 to return 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 movement component 64 operates in the reverse direction, thereby driving the pressure plate 63 to move up. At this time, the pressure plate 63 releases the fixation on the steel plate. Then, when the conveying plate 4 moves to the position of the discharge rack 738, the discharge rack 738 drives the transmission component 73 to operate, and the transmission component 73 operates to drive the reciprocating screw rod 72 to rotate. The reciprocating screw rod 72 rotates to drive the right-angle plate 71 to move toward the feeding port 9. The right-angle plate 71 moves to push the steel plate stamped on the conveying plate 4 to the discharge port 74. Then, the steel plate is pushed out from the conveying plate 4 by the right-angle plate 71 and falls through the discharge port 74, thereby completing the unloading. Afterwards, since the conveying plate 4 has not yet reached its original position, after the right-angle plate 71 completes the unloading of the steel plate, the conveying plate 4 will also Continue to move, at this time the unloading rack 738 continues to drive the transmission assembly 73 and the reciprocating screw 72 to continue to operate, at this time the reciprocating screw 72 drives the right-angle plate 71 to return to its original position after unloading, and after the right-angle plate 71 reaches its original position, the conveying plate 4 also reaches its original position, and then the steel plate is placed for the next stamping, thereby achieving the effect of automatically unloading the steel plate after stamping, thereby avoiding the time-consuming and labor-intensive problem of manual unloading, and can also achieve automatic fixing of the steel plate, and can also automatically demold the steel plate after stamping, and no additional operation is required after demolding, finally, the workers will not work under the stamping equipment, thereby greatly improving the safety of the workers at work.

The downward moving component 64 includes a mounting hole 641, a limiting hole 642 and a gear hole 643. The mounting hole 641 is opened on the conveying plate 4, and a self-locking screw 646 is rotatably connected in the mounting hole 641. The self-locking screw A moving block 648 is threadedly connected to the rod 646, and the moving block 648 is fixedly connected to the pressure plate 63.

After the fixed gear 645 moves to the position of the fixed rack 61, the fixed gear 645 engages with the fixed rack 61, and as the conveying plate 4 moves, the fixed rack 61 drives the fixed gear 645 to rotate, and the fixed gear 645 rotates to drive the self-locking screw 646 to rotate, and the self-locking screw 646 rotates to drive the moving block 648 to move, and the moving block 648 moves to drive the pressing plate 63 to move down along the limiting rod 644, and then the pressing plate 63 presses down and fixes the steel plate on the conveying plate 4, and then the fixed gear 645 moves along with the conveying plate 4's movement is separated from the fixed rack 61. At this time, with the cooperation of the self-locking screw 646, the pressure plate 63 can keep pressing down and fixing the steel plate. After the stamping is completed, the driving motor 24 drives the driving screw 21 to rotate in the opposite direction, thereby driving the conveying plate 4 to return to its position through the driving block 22. At this time, the fixed gear 645 passes through the fixed rack 61 again. At this time, the fixed rack 61 drives the fixed gear 645 to rotate in the opposite direction. At this time, the fixed gear 645 drives the pressure plate 63 to move up through the self-locking screw 646. At this time, the pressure plate 63 releases the fixation of the steel plate, thereby realizing the effect of automatically fixing and releasing the fixation of the steel plate. While improving the stamping effect, it also facilitates the subsequent unloading of the steel plate. In addition, the setting of the cross plate 647 can close both sides of the equipment body 1, thereby protecting the stamping equipment while preventing outsiders from contacting the stamping mechanism 3.

After the upper mold 34 moves downward, it contacts the steel plate on the conveying plate 4 and drives the steel plate to move downward. The downward movement of the steel plate drives the conveying plate 4 and the base 51 to move downward. The base 51 moves downward to extrude the demoulding spring 5, and then the steel plate is demoulded with the cooperation of the hydraulic cylinder 31, the upper mold 34 and the lower mold 32.

During this process, the unloading gear 737 contacts the unloading rack 738. At this time, as the conveying plate 4 returns to its position, the unloading rack 738 drives the unloading gear 737 to rotate.
