Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of battery boxes, and in particular to a CNC stamping forming equipment for battery boxes. Background Technology
[0002] The stamping forming equipment used in battery box production involves feeding aluminum sheets or strips into a stamping forming machine where they are pressed and squeezed into the shape within a mold under immense pressure. Chinese utility model patent CN219648542U discloses a stamping forming equipment for battery box production. This equipment uses a continuously moving lubricated guide mechanism to press spring rods and limiting posts, extruding aluminum profiles into the shape of a battery box shell. Simultaneously, the guide mechanism is lubricated during its up-and-down movement, extending the machine's lifespan and reducing the negative impact of resistance.
[0003] However, after the stamping device stamps the sheet metal, the formed sheet metal will get stuck in the lower mold and cannot be automatically discharged. The battery box needs to be manually removed by the staff, which is labor-intensive. Since the staff's hands have to be inserted under the upper mold, it is dangerous and the work efficiency is low. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a CNC stamping forming equipment for battery boxes that achieves automatic feeding and unloading through an ejection structure and a robotic arm, thereby reducing labor intensity and danger and improving work efficiency.
[0005] This utility model discloses a CNC stamping forming equipment for battery boxes, comprising a worktable, a lower die, a hydraulic cylinder, an upper platform, and an upper die. The lower die is mounted on the worktable, and a forming cavity is provided in the middle of the lower die. The fixed end of the hydraulic cylinder is mounted on the worktable, and the upper platform is mounted on the top of the piston rod of the hydraulic cylinder. The upper die is mounted on the lower end face of the upper platform, and the upper die is located above the lower die. It also includes a connecting plate, a push rod, and a robotic arm mechanism. An opening is provided at the bottom of the forming cavity of the lower die, and the upper part of the push rod is slidably inserted into the opening of the lower die. The upper end of the push rod is connected to the lower die. The bottom of the forming cavity of the mold is flush with the surface. The lower part of the push rod extends under the worktable. The upper end of the connecting plate is connected to the upper platform, and the lower end of the connecting plate is slidably connected to the lower part of the push rod. A limiting plate for the connecting plate is set in the middle of the push rod. The robotic arm mechanism is installed on the side of the upper platform. The robotic arm is used to clamp the sheet metal and transfer it between the lower and upper molds. During operation, the robotic arm mechanism clamps the sheet metal, and the piston rods of the two hydraulic cylinders extend, raising the upper platform so that the upper mold rises above the lower mold. At this time, the lower end of the connecting plate and the push rod are connected. The limit plate of the rod does not contact, and the upper end of the push rod is flush with the bottom of the forming cavity of the lower mold. The robotic arm transfers the sheet metal between the upper and lower molds. The piston rod of the hydraulic cylinder retracts, making the sheet metal slightly higher than the upper mold. The robotic arm releases the sheet metal, placing it on the lower mold. The robotic arm resets and moves out of the outer side of the upper platform. The piston rod of the hydraulic cylinder retracts, pressing the upper mold into the lower mold to stamp the sheet metal. The piston rod of the hydraulic cylinder extends, raising the upper platform, upper mold, and connecting plate, so that the upper mold is above the lower mold. When the lower end of the connecting plate... After contacting the limiting plate of the push rod, the piston rod of the hydraulic cylinder continues to extend, causing the connecting plate to raise the push rod through the limiting plate. This causes the upper end of the push rod to extend out of the forming cavity of the lower mold, thereby pushing the formed battery box out of the forming cavity of the lower mold. After the robotic arm clamps the plate, it is transferred to the lower part of the upper mold. During the transfer process of the robotic arm, the formed battery box is pushed out between the lower mold and the upper mold, realizing automatic feeding and unloading of the plate, reducing labor intensity. Since it is not necessary for a person to reach under the upper mold, the danger is reduced and the work efficiency is improved.
[0006] Preferably, the robotic arm mechanism includes a motor, a first arm, a second arm, two inner clamping plates, and a push cylinder. The motor is mounted on the side wall of the upper platform via a bracket, and the motor's output shaft is mounted on a sleeve. The inner ends of the first and second arms are rotatably mounted on the sleeve. The two inner clamping plates are respectively mounted on the inner side walls of the outer ends of the first and second arms. One end of the push cylinder is rotatably connected to the first arm, and the other end of the push cylinder is rotatably connected to the second arm. When the piston rod of the push cylinder retracts, it pulls the first and second arms inward toward each other, causing the two inner clamping plates to come closer together to clamp the material. When the output shaft of the motor rotates, it drives the first and second arms to rotate, transferring the material between the upper and lower molds. When the piston rod of the push cylinder extends, it causes the first and second arms to open, thereby releasing the material and achieving automatic feeding.
[0007] Preferably, it also includes multiple springs, and the two inner clamping plates are elastically mounted on the first arm and the second arm respectively by the multiple springs; the multiple springs elastically support the two inner clamping plates, making the two inner clamping plates more stable and reliable when clamping the plate.
[0008] Preferably, it also includes a lever, a torsion spring, and a buffer block. One end of the lever is rotatably mounted on the outer end of the second arm. The two ends of the torsion spring are respectively connected to the lever and the second arm. The other end of the lever is equipped with a buffer block. When the motor drives the first and second arms to rotate, the second arm drives the lever to rotate between the upper and lower molds, so that the torsion spring pushes out the formed battery box through the buffer block, which facilitates fast and safe unloading.
[0009] Preferably, it also includes a material support plate, which is installed on the side of the workbench and located below the first and second arms; the material is placed on the material support plate, so that the first and second arms can hold the material through the two inner clamping plates.
[0010] Preferably, it also includes a positioning pin and a positioning seat. The positioning pin is installed on the material support plate, and the positioning seat is installed on the second arm. The positioning seat matches the positioning pin. When the upper platform drives the motor and the first and second arms descend, the positioning pin is inserted into the positioning seat to position the first and second arms, thereby improving the clamping accuracy of the material.
[0011] Preferably, it also includes multiple sliding rods and multiple springs. The lower ends of the multiple sliding rods are mounted on the side of the workbench via a horizontal plate. The material support plate is slidably mounted on the multiple sliding rods. The lower ends of the multiple springs are connected to the horizontal plates of the multiple sliding rods, and the upper ends of the multiple springs are connected to the material support plate. The multiple springs elastically support the material support plate, and the multiple sliding rods slide and guide the material support plate, so that the material support plate elastically supports multiple plates, making the overall height of the multiple stacked plates basically stable. This facilitates the use of the first and second arms to drive the two inner clamping plates to clamp the uppermost plate, improving practicality.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: During operation, the robotic arm clamps the sheet metal, the piston rods of the two hydraulic cylinders extend, raising the upper platform so that the upper mold rises above the lower mold. At this time, the lower end of the connecting plate does not contact the limiting plate of the push rod, and the upper end of the push rod is flush with the bottom of the forming cavity of the lower mold. The robotic arm transfers the sheet metal between the upper and lower molds. The piston rods of the hydraulic cylinders retract, making the sheet metal slightly higher than the upper mold. The robotic arm releases the sheet metal, placing it on the lower mold. The robotic arm resets and moves out of the outer side of the upper platform. The piston rods of the hydraulic cylinders retract, pressing the upper mold into the lower mold to stamp the sheet metal. The piston rod of the cylinder extends, raising the upper platform, upper mold, and connecting plate, so that the upper mold is above the lower mold. When the lower end of the connecting plate contacts the limiting plate of the push rod, the piston rod of the hydraulic cylinder continues to extend, causing the connecting plate to raise the push rod through the limiting plate, so that the upper end of the push rod extends out of the forming cavity of the lower mold, thereby pushing the formed battery box out of the forming cavity of the lower mold. After the robotic arm clamps the plate, it is transferred to the lower part of the upper mold. During the transfer process of the robotic arm, the formed battery box is pushed out between the lower mold and the upper mold, realizing automatic feeding and unloading of the plate, reducing labor intensity. Since it is not necessary to reach under the upper mold, the danger is reduced and the work efficiency is improved. Attached Figure Description

[0019] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1
[0020] like Figures 1 to 4 As shown, a CNC stamping forming equipment for battery boxes includes a worktable 1, a lower mold 2, a hydraulic cylinder 3, an upper platform 4, and an upper mold 5. The lower mold 2 is mounted on the worktable 1, and a forming cavity is provided in the middle of the lower mold 2. The fixed end of the hydraulic cylinder 3 is mounted on the worktable 1. The upper platform 4 is mounted on the top of the piston rod of the hydraulic cylinder 3. The upper mold 5 is mounted on the lower end surface of the upper platform 4 and is located above the lower mold 2. The equipment also includes a connecting plate 6, a push rod 7, and a robotic arm mechanism. An opening is provided at the bottom of the forming cavity of the lower mold 2. The upper part of the push rod 7 is slidably inserted into the opening of the lower mold 2, and the upper end of the push rod 7 is flush with the bottom of the forming cavity of the lower mold 2. The lower part of the push rod 7 extends into the lower part of the worktable 1. The upper end of the connecting plate 6 is connected to the upper platform 4, and the lower end of the connecting plate 6 is slidably connected to the lower part of the push rod 7. A limiting plate of the connecting plate 6 is provided in the middle of the push rod 7. The robotic arm mechanism is mounted on the side of the upper platform 4 and is used to clamp the sheet metal and transfer it between the lower mold 2 and the upper mold 5.
[0021] During operation, the robotic arm clamps the sheet metal, and the piston rods of the two hydraulic cylinders 3 extend, raising the upper platform 4 so that the upper mold 5 rises above the lower mold 2. At this time, the lower end of the connecting plate 6 does not contact the limiting plate of the push rod 7, and the upper end of the push rod 7 is flush with the bottom of the forming cavity of the lower mold 2. The robotic arm transfers the sheet metal between the upper mold 5 and the lower mold 2. The piston rods of the hydraulic cylinders 3 retract, making the sheet metal slightly higher than the upper mold 5. The robotic arm releases the sheet metal, placing it on the lower mold 2. The robotic arm then resets and moves out of the outer side of the upper platform 4. The piston rods of the hydraulic cylinders 3 retract, pressing the upper mold 5 into the lower mold 2 to stamp the sheet metal. The piston rods of the hydraulic cylinders 3 extend... The upper platform 4, upper mold 5, and connecting plate 6 are raised so that the upper mold 5 is above the lower mold 2. When the lower end of the connecting plate 6 contacts the limiting plate of the push rod 7, the piston rod of the hydraulic cylinder 3 continues to extend, causing the connecting plate 6 to raise the push rod 7 through the limiting plate. This causes the upper end of the push rod 7 to extend out of the forming cavity of the lower mold 2, thereby pushing the formed battery box out of the forming cavity of the lower mold 2. After the robotic arm clamps the plate, it is transferred to the lower part of the upper mold 5. During the transfer process of the robotic arm, the formed battery box is pushed out between the lower mold 2 and the upper mold 5, realizing automatic feeding and unloading of the plate, reducing labor intensity. Since it is not necessary for a person to reach under the upper mold, the danger is reduced and the work efficiency is improved. Example 2
[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, based on Embodiment 1, the robotic arm mechanism includes a motor 8, a first arm 9, a second arm 10, two inner clamping plates 11, and a push cylinder 12. The motor 8 is mounted on the side wall of the upper platform 4 via a bracket. The output shaft of the motor 8 is mounted on a sleeve. The inner ends of the first arm 9 and the second arm 10 are rotatably mounted on the sleeve. The two inner clamping plates 11 are respectively mounted on the inner side walls of the outer ends of the first arm 9 and the second arm 10. One end of the push cylinder 12 is rotatably connected to the first arm 9, and the other end of the push cylinder 12 is rotatably connected to the second arm 10. It also includes multiple springs 13, with the two inner clamping plates 11 elastically mounted on the first arm 9 and the second arm 10 via the multiple springs 13. Furthermore, it includes a lever 14, a torsion spring 15, and a buffer block 16. One end of the lever 14 is rotatably mounted on the second arm 10. At the outer end of 10, the two ends of the torsion spring 15 are respectively connected to the lever 14 and the second arm 10, and the other end of the lever 14 is equipped with a buffer block 16; it also includes a material support plate 21, which is installed on the side of the workbench 1 and is located below the first arm 9 and the second arm 10; it also includes a positioning pin 17 and a positioning seat 18, with the positioning pin 17 installed on the material support plate 21 and the positioning seat 18 installed on the second arm 10, and the positioning seat 18 matching the positioning pin 17; it also includes multiple slide rods 19 and multiple second springs 20, with the lower ends of the multiple slide rods 19 installed on the side of the workbench 1 through a horizontal plate, the material support plate 21 slidingly installed on the multiple slide rods 19, the lower ends of the multiple second springs 20 connected to the horizontal plate of the multiple slide rods 19, and the upper ends of the multiple second springs 20 connected to the material support plate 21.
[0023] The sheet metal is placed on the support plate 21, and multiple springs 20 elastically support the support plate 21. Multiple sliding rods 19 guide the support plate 21 to slide, so that the support plate 21 elastically supports multiple sheet metals, keeping the overall height of the stacked sheet metals basically stable. When the upper platform 4 drives the motor 8, arm 1 9, and arm 2 10 to descend, the positioning pin 17 is inserted into the positioning seat 18 to position arm 1 9 and arm 2 10, improving the clamping accuracy of the sheet metal. The piston rod of the push cylinder 12 retracts, pulling arm 1 9 and arm 2 10 inwards relative to each other, so that the two inner clamping plates 11 are close together for clamping. The uppermost plate is supported by multiple springs 13, which elastically support two inner clamping plates 11, making the clamping of the plate more stable and reliable. The output shaft of the motor 8 rotates, driving the first arm 9 and the second arm 10 to rotate, transferring the plate between the upper mold 5 and the lower mold 2. The second arm 10 drives the lever 14 to rotate between the upper mold 5 and the lower mold 2, so that the torsion spring 15 pushes out the formed battery box through the buffer block 16, facilitating fast and safe unloading. The piston rod of the push cylinder 12 extends, causing the first arm 9 and the second arm 10 to open, thereby releasing the plate onto the lower mold 2, realizing automatic feeding.
[0024] like Figures 1 to 5 As shown, this utility model discloses a CNC stamping forming equipment for battery boxes. During operation, the material support plate 21 elastically supports multiple plates. The piston rod of the push cylinder 12 retracts, pulling the first arm 9 and the second arm 10 inwards towards each other, causing the two inner clamping plates 11 to clamp the plates. The piston rods of the two hydraulic cylinders 3 extend, raising the upper platform 4, causing the upper mold 5 to rise above the lower mold 2. At this time, the lower end of the connecting plate 6 does not contact the limiting plate of the push rod 7, and the upper end of the push rod 7 is flush with the bottom of the forming cavity of the lower mold 2. Then, the motor 8 drives the first arm 9 and the second arm 10 to rotate between the upper mold 5 and the lower mold 2. The piston rod of the hydraulic cylinder 3 retracts, causing the plates to be slightly higher than the upper mold 5. The push cylinder 12 extends, releasing the plates and placing them on the lower mold 2. Then, the motor 8 drives the first arm 9 and the second arm 10 to reset and move out of the outer side of the upper platform 4. The piston rod of the hydraulic cylinder 3 retracts, causing the upper mold 5 to press into the lower mold 2. In mold 2, the sheet metal is stamped and formed. At this time, the push cylinder 12 retracts, causing the first arm 9 and the second arm 10 to drive the two inner clamping plates 11 to clamp another sheet metal. The piston rod of the hydraulic cylinder 3 extends, raising the upper platform 4, the upper mold 5, and the connecting plate 6, so that the upper mold 5 is above the lower mold 2. When the lower end of the connecting plate 6 contacts the limiting plate of the push rod 7, the piston rod of the hydraulic cylinder 3 continues to extend, causing the connecting plate 6 to raise the push rod 7 through the limiting plate, so that the upper end of the push rod 7 extends out of the forming cavity of the lower mold 2, thereby pushing the formed battery box out of the forming cavity of the lower mold 2. Finally, the motor 8 drives the first arm 9 and the second arm 10 to move again between the upper mold 5 and the lower mold 2, so that the second arm 10 drives the lever 14 to rotate between the upper mold 5 and the lower mold 2, so that the torsion spring 15 pushes the formed battery box out between the lower mold 2 and the upper mold 5 through the buffer block 16, thus realizing the automatic feeding and unloading of the sheet metal.
