Technical Field

[0001] The utility model belongs to the technical field of molds, and in particular relates to a punching mold for reinforcing side panels of a new energy battery pack. Background Art

[0002] The structure of the battery consists of components such as the outer shell, the upper cover, the plates, the partitions, the busbars, the poles, the bridge protection plates, and the terminals. At present, in the processing of the battery shell, it is often necessary to use stamping equipment to stamp and form raw materials such as metal iron to prepare the battery shell. When the stamping equipment works, it relies on the hydraulic cylinder and the mold to apply external force to the plates, strips, pipes and profiles to cause plastic deformation or separation, so as to obtain the workpiece of the required shape and size. When the stamping device processes the battery shell, the material needs to be fixed in advance, and the materials required for different battery shells are of different sizes. Different materials are prone to movement during processing, thereby causing damage to the material.

[0003] To this end, a battery shell stamping device with the announcement number "CN219746058U" includes a support base, a workbench is arranged at the central position of the top of the support base, accessory slots are opened at both ends of the inside of the workbench, a support rod is arranged inside the accessory slot, a movable block is slidably arranged outside the support rod, a fixed plate is arranged at the end of the movable block close to the center point of the inside of the workbench, a limited insertion rod is arranged through the top of the movable block, support columns are arranged around the top of the support base, a top plate is arranged at the top of the support column, a hydraulic cylinder is arranged at the central position of the bottom of the top plate, a fixed seat is arranged at the output end of the hydraulic cylinder, and a stamping die is arranged through the inside of the fixed seat.

[0023] See also Figure 1-3 The utility model provides a technical solution: a new energy battery pack reinforcement side plate stamping die, comprising:

[0024] A mold base 1, wherein the end of the mold base 1 is provided with a lower mold 2 for supporting and stamping the plate, and the lower mold 2 is fixed to the mold base 1 by bolts, so as to facilitate the disassembly, assembly and replacement of the lower mold 2 in the later stage. A movable upper mold 4 for stamping and clamping with the lower mold 2 is installed at the end of the mold base 1 through a frame 3, and the movable upper mold 4 is pneumatically reciprocated downward to realize continuous clamping with the lower mold 2 to stamp the plate of the reinforced side plate, and positioning slide plates 5 for positioning the movable upper mold 4 for active stamping are provided at both ends of the inner side of the frame 3, so that the movable upper mold 4 can be positioned and reciprocated on the positioning slide plates 5 while moving downward, so as to ensure the stability of the reciprocating stamping movement of the movable upper mold 4 and improve the accuracy of clamping between the movable upper mold 4 and the lower mold 2;

[0025] The lifting and conveying material plate 6 has an elastic telescopic part 7 at the bottom that is conducive to the lifting and resetting of the lifting and conveying material plate 6. The elastic telescopic part 7 is a socket-jointed composite component of a sleeve seat and a movable telescopic rod, and a spring part is socketed on the movable telescopic rod, which is conducive to the lifting and conveying material plate 6 to rebound and reset after being pressed and pressed with the lower mold 2, and is conducive to demolding the formed reinforced side panel. There is no need for personnel to manually perform demolding operations, and excess scraps can be removed by using the trimming equipment. Pneumatic frames 8 for stamping and pressing the side panel materials are provided on both sides of the upper end surface of the lifting and conveying material plate 6, which can position the reinforced side panel during transportation to avoid deviation, and conveying rollers 9 for conveying the side panel coils are longitudinally installed on both sides of the surface of the lifting and conveying material plate 6, so as to achieve the effect of continuous transportation of the reinforced side panel materials.

[0026] The interior of the pneumatic frame 8 is provided with a downward pressing cylinder 10, which is used to push the positioning pressure plate 11 downward to press down and position the two ends of the reinforced side plate during the stamping process to avoid the phenomenon of unstable vibration. The bottom of the piston rod of the downward pressing cylinder 10 is provided with a positioning pressure plate 11 for pressing the conveyed side plate coil. The positioning pressure plate 11 can press down and position the plate of the reinforced side plate to ensure the stability of the plate during the stamping process. A servo motor 12 is provided on one side of the outside of the lifting and conveying material plate 6. The servo motor 12 drives the conveying roller 9 to rotate to achieve the effect of staged continuous conveying of the plate. The rotating shaft of the servo motor 12 is connected to the rotating shaft at one end of the conveying roller 9 through a transmission connection. A stamping through-hole groove 13 is provided on the surface of the lifting and conveying material plate 6, which can make the lifting and conveying material plate 6 move downward and be integrated with the lower mold 2 through the stamping through-hole groove 13, and the two sides of the lifting and conveying material plate 6 are provided with upwardly extending material blocking strips 14 to avoid the phenomenon of position displacement during plate stamping and reduce the phenomenon of scrapping of the plate.

[0027] The lower die 2 and the movable upper die 4 are both provided with a disassembly die bottom plate 15 on one side, which is conducive to the disassembly and replacement of the die, and reduces the use cost of the die. The disassembly die bottom plate 15 is locked and fixed with the lower die 2 and the movable upper die 4 by screws, so that the lower die 2 and the movable upper die 4 can be replaced with new die after serious wear in the later stage. The bottom of the crossbeam of the frame 3 is symmetrically provided with a stamping cylinder 16 to realize the reciprocating stamping movement of the movable upper die 4 and perform continuous stamping and forming actions. The stamping cylinder 16 is connected to one side of the disassembly die bottom plate 15 on the movable upper die 4 to realize the continuous stamping and clamping of the movable upper die 4 and the lower die 2. The positioning slide plate 5 is symmetrically fixed on the bottom side of the crossbeam of the frame 3, and a supporting side rod 17 is provided on one side of the positioning slide plate 5 for supporting one side of the positioning slide plate 5. The other end of the supporting side rod 17 is fixed on the vertical rods on both sides of the inside of the frame 3 to improve the stability of the positioning slide plate 5 during use and avoid bending and deformation.

[0028] Specifically, when in use, first install the mold at the specified position through the mold base 1, then pull the rolled sheet through the pneumatic frame 8 on the left side of the lifting and conveying plate 6 to the upper end of the lower mold 2, and make the sheet cover the punching through-hole groove 13. At this time, the punching cylinder 16 pushes the movable upper mold 4 downward through the disassembling mold bottom plate 15. While the movable upper mold 4 moves downward, it pushes the lifting and conveying plate 6 to move downward, and the elastic telescopic member 7 shrinks accordingly, so that the lifting and conveying plate 6 is pressed against the surface of the lower mold 2, and the downward pressing cylinder 10 pushes the positioning pressing plate 11 downward to position and press the sheet, so that the sheet can remain stable and not deviate during the punching process. Then the movable upper mold 4 and the lower mold 2 are combined to punch the pressed sheet. After the punching is completed, the punching cylinder 16 drives the disassembling mold bottom plate 15 to The movable upper mold 4 moves up and away from the lower mold 2. As the movable upper mold 4 moves up, the lifting and conveying plate 6 automatically moves up by utilizing the elasticity of the compressed elastic telescopic member 7, and the formed reinforcing side plate is separated from the lower mold 2 and moves up, so that the molded part can be demoulded. Then the pressing cylinder 10 retracts to drive the positioning plate 11 to move back, and the servo motor 12 starts and drives the conveying rollers 9 at both ends of the lifting and conveying plate 6 to rotate through the rotating shaft. The rotating shell of the conveying roller 9 drives the lifted plate to be output to the discharge end of the mold. At this time, the stamped plate is transported to the surface of the stamping through-hole groove 13 and stops. During the stamping process of the above-mentioned mold, the plate is phasedly conveyed to the vertical upper end of the lower mold 2 for continuous stamping, thereby eliminating the need for staff to manually take and place the molded parts, further improving the stamping efficiency.
