[0022] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The role of the drawings is to supplement the description in the text part of the specification, enabling people to visually and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.

[0023] Refer to Figures 1-4, in an embodiment of the utility model, a stamping die for precision sheet metal parts includes a workbench 1, a template 2 disposed inside the workbench 1, a stamping plate 3 disposed above the template 2, and two conveyor belts 4 disposed on both sides of the workbench 1. Two support plates 9 both configured in a U-shaped structure are symmetrically and movably connected to the bottom of the workbench 1. A control component for driving the support plates 9 to move up and down is disposed below the support plates 9 at the bottom of the workbench 1. The two support plates 9 move up and down through the control component, thereby driving the frame 11 and the rollers 12 to perform corresponding lifting and lowering. A plurality of fixing rods 10 are evenly and fixedly connected to the top of the support plates 9. The top of each two opposite fixing rods 10 is fixedly connected with a frame 11 configured in a U-shaped structure, and rollers 12 are rotatably connected to the inner sides of the frames 11. A through groove 13 is formed inside the workbench 1 above the frame 11, and the frames 11 can move up and down inside the corresponding through grooves 13;

[0024] To realize the rotation of the rollers 12, a driving component is disposed on the top of one of the support plates 9 and on one side of the frame 11. The driving component is used to drive the rollers 12 at both ends and in the middle to rotate.

[0025] The conveyor belts 4 are used to respectively feed the sheet metal parts to be processed into the die and send out the processed sheet metal parts. When the sheet metal parts are fed in, the control component drives the frame 11 and the rollers 12 to move upward, and drives the rollers 12 to rotate through the driving component. At this time, under the action of the rotating rollers 12, the sheet metal parts can be fed above the template 2. While the rollers 12 move downward into the through groove 13 through the control component, the sheet metal parts are located on the template 2 and can be stamped by the stamping plate 3. After stamping, the control component drives the rollers 12 to move upward and lift the sheet metal parts, and the driving component drives the rollers 12 to rotate to convey the processed sheet metal parts to the right conveyor belt 4, completing the entire processing process, ensuring the smooth feeding and sending out of the sheet metal parts by the die. The automated operation mode can greatly reduce the time and labor intensity of manual operation, thereby improving the processing efficiency.

[0026] The control component includes two fixing frames 5 symmetrically and fixedly connected to the bottom of the workbench 1 and both configured in a U-shaped structure, two cylinders 6 fixedly connected to the tops of the corresponding fixing frames 5, and two connecting plates 8 fixedly connected to the piston rods of the corresponding cylinders 6. Both ends of the two support plates 9 are fixedly connected to the adjacent connecting plates 8. By controlling the expansion and contraction of the cylinders 6 to drive the connecting plates 8 to move up and down, the lifting height of the support plates 9 can be accurately controlled, thereby driving the frame 11 and the rollers 12 to perform corresponding lifting and lowering.

[0027] The driving assembly includes three transmission components arranged at equal intervals, a coupling shaft 20 rotatably connected to the inner side of the support plate 9, and a motor 21 fixedly connected to one side of the support plate 9. When the motor 21 operates, it drives the coupling shaft 20 to rotate, and the power can be transmitted through the transmission components to drive the roller 12 to rotate. The transmission components include two meshing bevel gears 15, a fixing plate 16 fixedly connected to the outside of the frame 11, a connecting rod 17 rotatably connected to the inside of the fixing plate 16 and rotatably connected to the support plate 9 at the bottom, a worm gear 18 fixedly connected to the outside of the connecting rod 17 and near the bottom, and a worm 19 meshing with the worm gear 18. The two bevel gears 15 are respectively fixedly connected to the top of the connecting rod 17 and one end of the central axis of the roller 12. The worm 19 is fixedly connected to the outside of the coupling shaft 20, and one end of the coupling shaft 20 close to the motor 21 penetrates through the inside of the support plate 9 and is fixedly connected to the output shaft of the motor 21.

[0028] Driven by the motor 21, the coupling shaft 20 drives the worm 19 to rotate, thereby driving the worm gear 18 and the connecting rod 17 to rotate, realizing the rotation of the roller 12.

[0029] To facilitate the control of the operation of the entire mold, a controller 14 is provided on one side of the top of the workbench 1 and near the edge. Both the motor 21 and the cylinder 6 are electrically connected to the controller 14. The start and stop of the motor 21 and the telescoping of the cylinder 6 can be conveniently controlled through the controller 14.

[0030] To ensure the stable lifting of the support plate 9, guide rods 7 are slidably connected to the inside of the two fixing frames 5 and on both sides of the cylinder 6. The tops of every two adjacent guide rods 7 are fixedly connected to the bottom of the adjacent connecting plate 8. When the cylinder 6 expands and contracts, the guide rods 7 can provide stable support and guidance for the connecting plate 8 and the support plate 9.

[0031] To ensure the smooth cooperation between the conveyor belt 4 and the workbench 1, the top of the conveyor belt 4 is slightly higher than the workbench 1, and the rising height of the roller 12 is flush with the top of the conveyor belt 4, so that the sheet metal parts can be smoothly transferred onto the workbench 1.

[0032] Working principle: When the sheet metal parts are fed in, control the cylinder 6 to operate to drive the frame 11 and the roller 12 to move upward, and drive the coupling shaft 20 to drive the worm 19 to rotate through the motor 21, so as to drive the worm gear 18 and the connecting rod 17 to rotate, realizing the rotation of the roller 12. At this time, under the action of the rotating roller 12, the sheet metal parts can be fed above the template 2. When the roller 12 moves downward into the through groove 13 through the operation of the cylinder 6, the sheet metal parts are located above the template 2. Through the assistance of the operator for precise positioning, the stamping work can be carried out through the stamping plate 3;

[0033] After stamping, the cylinder 6 operates to drive the roller 12 to move upward and lift the sheet metal part. The motor 21 operates to drive the roller 12 to rotate and convey the processed sheet metal part to the right conveyor belt 4, completing the entire processing process, ensuring the smooth feeding and discharging of the sheet metal part by the mold. The automated operation mode can greatly reduce the manual operation time and labor intensity, thereby improving the processing efficiency.

[0034] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art in the said technical field, various changes can also be made without departing from the gist of the present invention.
