Description

Technical Field

[0001] This utility model relates to stamping equipment, specifically to a high-precision stamping equipment. Background Technology

[0002] Stamping equipment is mainly used for stamping and forming of stamping substrates. One type of stamping equipment has different stamping punches and corresponding stamping dies arranged on the upper and lower dies. With this stamping structure, only one set of upper and lower dies is needed. By controlling the gradual movement of the stamping substrate to cooperate with the stamping, multiple different stamping processes can be completed to obtain the desired stamped product. Traditional stamping equipment generally uses a gripper structure to clamp the stamping substrate and move it, thereby achieving step-by-step feeding of the stamping substrate. With this feeding method, the gripper structure needs to keep the stamping substrate clamped, which requires the upper and lower dies to be at the same clamping height of the stamping substrate for stamping. However, in actual operation, because both the upper and lower dies move and the stroke of the hydraulic cylinder changes slightly during long-term operation, the stamping height of the upper and lower dies often cannot be kept consistent with the clamping height of the stamping substrate. This causes the stamping substrate to undergo a certain degree of tensile deformation during stamping, affecting the stamping accuracy and forming quality. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a high-precision stamping device for solving the above-mentioned problems.

[0004] Therefore, this utility model is implemented using the following solution:

[0005] A high-precision stamping device includes an upper die and a lower die set at a stamping station. The upper die and the lower die are connected to corresponding lifting drive components. Different stamping punches are arranged at the bottom of the upper die, and stamping dies that cooperate with the stamping punches are arranged at the top of the lower die. The device is characterized by further including a material support plate, which is set on both sides of the upper and lower dies. The material support plate has light-transmitting holes, a light source is set below the material support plate, and a monitoring camera is set above the material support plate. The stamping substrate can be placed against the material support plate with both ends extending out of the material support plate. The device also includes a pushing component, which includes a pushing element set on a lifting frame. The lifting frame is movably set on a movable frame and connected to the lifting drive component. The movable frame is movably set on a base and connected to the movable drive component. The monitoring camera can control the movement of the movable drive component.

[0006] The lifting drive assembly includes a first hydraulic cylinder and a second hydraulic cylinder. The piston rod of the first hydraulic cylinder is connected to the upper mold, and the piston rod of the second hydraulic cylinder is connected to the lower mold.

[0007] The lifting drive assembly includes a first cylinder, the cylinder body of which is mounted on a movable frame, the piston rod of which is connected to the lifting frame, and a guide column passing through the lifting frame is provided on the movable frame.

[0008] The pusher is positioned at four corners and is attached to both sides of the corner of the stamping substrate.

[0009] The mobile drive assembly includes a drive motor, the output end of which is connected to a drive screw, the drive screw is screwed to a mobile frame, a slide block is provided on the mobile frame, and a slide rail that cooperates with the slide block is provided on the base.

[0010] The high-precision stamping equipment described above, by setting up a support plate and a pusher, allows the stamping substrate to rest against the support plate and be moved by the pusher. A light-transmitting hole is provided on the support plate, and under the influence of a light source, a monitoring camera can image the position of the stamping substrate, thereby controlling the stroke of the pusher to ensure that the stamping substrate is pushed into place and guaranteeing stamping accuracy. During the stamping process, as the lower die rises, it first lifts the stamping substrate upwards and separates it from the support plate, and then cooperates with the upper die to perform the stamping operation. This prevents the stamping substrate from being stretched or deformed during the stamping process, ensuring stamping accuracy and forming quality. Attached Figure Description

[0015] As shown in the figure, the present invention discloses a high-precision stamping equipment, including an upper die 11 and a lower die 9 set in the stamping station. The upper die 11 and the lower die 9 are connected to corresponding lifting drive components. Specifically, the lifting drive components include a first oil cylinder 12 and a second oil cylinder 8. The piston rod of the first oil cylinder 12 is connected to the upper die 11, and the piston rod of the second oil cylinder 8 is connected to the lower die 9. The upper die 11 has different stamping punches 19 arranged at its bottom, and the lower die 9 has stamping dies 18 arranged at its top to cooperate with the stamping punches 19. It also includes a material support plate 10, which is located on both sides of the upper and lower dies. The material support plate 10 has light-transmitting holes 16 arranged on it. A light source is located below the material support plate 10, and a monitoring camera 17 is located above it. The stamping substrate 14 can rest on the material support plate 10 and its two ends extend out of the material support plate 10. It also includes a pusher assembly, which includes a pusher 13. The pusher 13 is located on a lifting frame 15. The lifting frame 15 is movably located on a movable frame 5 and connected to a lifting drive assembly. Specifically, the lifting drive assembly includes a first cylinder 6. The cylinder body of the first cylinder 6 is located on the movable frame 5. The piston rod of the first cylinder 6 is connected to the lifting frame 15. The movable frame 5 has a guide post that passes through the lifting frame 15. By controlling the action of the first cylinder 6, the lifting frame 15 and the pusher 13 can be driven to move up and down. The movable frame 5 is movably mounted on the base 2 and connected to the movable drive assembly. Specifically, the movable drive assembly includes a drive motor 1, the output end of which is connected to a drive screw 7. The drive screw 7 is screwed to the movable frame 5. A slide block 3 is provided on the movable frame 5, and a slide rail 4 that cooperates with the slide block 3 is provided on the base 2. By controlling the drive motor 1 to drive the drive screw 7 to rotate, the movable frame 5 can be driven to move horizontally along the slide rail 4. The monitoring camera 17 can control the action of the movable drive assembly. Furthermore, the pusher 13 is arranged at four corners and is attached to both sides of the corners of the stamping substrate 14. In this embodiment, the pusher 13 is L-shaped, so that it can be attached to both sides of the four corners of the rectangular stamping substrate 14. With this structure, the four corners of the stamping substrate 14 can be positioned to ensure the stability of the pushing process. During the lifting and lowering of the lower die 9, the pusher 13 can guide the lifting and lowering of the stamping substrate 14 to ensure that its horizontal position does not shift, thereby improving the stamping accuracy.

[0016] The working principle of this utility model is as follows: First, the stamping substrate 14 is placed on the support plate 10. Then, the lifting seat 15 is controlled to drive the pusher 13 to rise above the stamping substrate 14, and the moving frame 5 is controlled to move, so that the pusher 13 pushes the stamping substrate 14 to the stamping station. The light source passes through the light-transmitting hole 16. As the stamping substrate 14 moves, it will block the light-transmitting hole 16, so that the monitoring camera 17 can accurately monitor the position of the stamping substrate 14. When the stamping substrate 14 moves into place, the moving frame 5 stops moving. Cylinder 8 drives the lower die 9 to rise and lift the stamping substrate 14 away from the support plate 10. The first oil cylinder 12 also drives the upper die 11 to fall, so that the upper die 11 and the lower die 9 can cooperate to stamp the stamping substrate 14. After that, the upper and lower dies are reset, and the stamping substrate 14 is placed back on the support plate 10. The moving frame 5 drives the pusher 13 to push the stamping substrate 14 to continue moving until the monitoring camera 17 feeds back the positioning information. Then the lower die 9 and the upper die 11 work together again to stamp the stamping substrate. This cycle is repeated until the entire stamping operation is completed.

[0017] This invention features a structure with a support plate and a pusher. The stamping substrate can be placed on the support plate and moved by the pusher. The support plate has light-transmitting holes, and a monitoring camera can image the position of the stamping substrate under the influence of a light source, thereby controlling the stroke of the pusher to ensure that the stamping substrate is pushed into place and to guarantee stamping accuracy. During the stamping process, as the lower die rises, it first lifts the stamping substrate upwards and separates it from the support plate before cooperating with the upper die to perform the stamping operation. This prevents the stamping substrate from being stretched or deformed during the stamping process, ensuring stamping accuracy and forming quality.
