Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, and more particularly to a stamping die for an automobile reinforcement plate. Background Art

[0002] Auto parts are the components that make up a car and are products that serve the car. There are many different types of auto parts, and with the increasing number of car brands and types, stamping dies are required when stamping automotive reinforcement plates and partitions to facilitate punching or shaping the surface of the reinforcement plates.

[0003] For example, a stamping die for automobile reinforcement plates, with announcement number CN216911802U, includes a lower die, with guide rods fixedly mounted at the four corners of the top of the lower die, and guide posts provided at the tops of the guide rods, the guide posts being slidably connected to the guide rods. The utility model provides a placement platform, a stamping platform, a knob, and a connecting ring. When stamping the reinforcement plate, the reinforcement plate needs to be placed on the placement platform, and then a pneumatic mechanism pushes the upper die downward, pushing the bottom stamping platform downward. The bottom stamping rod is then used to stamp the reinforcement plate on the placement platform. When the reinforcement plate is changed, only the stamping platform and the placement platform need to be replaced.

[0004] The automotive reinforcement plate stamping die proposed in the aforementioned patent document, like most existing stamping dies, requires a positioning mechanism with bolts to limit and secure the workpiece surface. However, when continuously stamping different positions on the workpiece surface, the positioning mechanism must be manually released and then fixed, which is cumbersome and inconvenient for continuous workpiece feeding and positioning. Therefore, there is a need to improve this problem of existing stamping dies. Utility Model Content

[0026] Through the above technical solution, the left and right sides of the base 1 are fixedly connected with a transmission box 7, the inner wall of the transmission box 7 is fixedly connected with a partition, the surface of the partition is rotatably connected with a transmission rod 8, the top end of the transmission rod 8 is fixedly connected with a first transmission gear 9, and the bottom end of the transmission rod 8 is fixedly connected with a second transmission gear 10.

[0027] A power chamber is opened inside the base 1, and a dual-axis motor 12 is fixedly installed on the inner bottom wall of the power chamber. The two output ends of the dual-axis motor 12 are fixedly connected to the driving rod 13, and the ends of the two driving rods 13 away from each other extend to the interior of the transmission box 7 and are fixedly connected to the driving gear 14. The position of the driving gear 14 corresponds to the second transmission gear 10, and the driving gear 14 is engaged with the second transmission gear 10.

[0028] Through the above technical solution, the limiting guide mechanism 6 includes a fixed seat 601 fixedly connected to the side of the moving block 5, and a rectangular adjustment groove 602 is opened on the surface of the fixed seat 601. The inner bottom wall of the rectangular adjustment groove 602 is rotatably connected with a lifting screw 603. The top of the lifting screw 603 extends to the outside of the rectangular adjustment groove 602, and the top of the lifting screw 603 is fixedly connected with an adjusting nut 612. The surface of the lifting screw 603 is threadedly connected with an adjusting block 604. The adjusting block 604 is slidably connected to the inner wall of the rectangular adjustment groove 602. The side of the adjusting block 604 is fixedly connected to a limiting frame 605. The limiting frame 605 has an L-shaped structure, and a plurality of guide wheels 606 are rotatably provided on the surface of the limiting frame 605.

[0029] Through the above technical solution, the guide wheel 606 can be used to limit and guide the surface of the reinforcement plate, thereby facilitating the movement and feeding of the reinforcement plate on the base 1.

[0030] It is worth noting that by providing the linkage screw rod 4, the dual-axis motor 12 can be used to drive the linkage screw rod 4 to adjust and position the distance between the two limiting frames 605, thereby being suitable for limiting workpieces of different widths.

[0031] Through the above technical solution, a limiting motor 607 is fixedly installed on the surface of the limiting frame 605, and the output shaft of the limiting motor 607 extends to the top of the limiting frame 605 and is fixedly connected to the limiting screw rod 608. The top of the limiting screw rod 608 is fixedly connected to an anti-disengagement block 613.

[0032] It is worth noting that by setting up the lifting screw 603, the lifting screw 603 can be driven to rotate by adjusting the nut 612, and then the height of the limit frame 605 can be adjusted, which is suitable for limiting plates of different thicknesses and improves the practicality of the limit guide mechanism 6.

[0033] The surface of the limiting screw 608 is threadedly connected to a lifting plate 609, and the lower surface of the lifting plate 609 is fixedly connected to a number of positioning columns 610. The several positioning columns 610 and the several guide wheels 606 are staggered and distributed on the surface of the limiting frame 605. By setting an anti-slip block 613, the lifting plate 609 on the surface of the limiting screw 608 can be prevented from slipping and limited.

[0034] By arranging the positioning posts 610 and the guide wheels 606 that are staggered with each other, the positioning posts 610 can be moved up and down in the gap between two adjacent guide wheels 606 , thereby facilitating the positioning of the reinforcement plate using the positioning posts 610 .

[0035] It is worth noting that by arranging a limiting guide mechanism 6 on the surface of the mold base 1, when the automobile reinforcement plate is stamped, the surface of the reinforcement plate can be pressed and limited by a number of guide wheels 606 on the surface of the two limiting frames 605, and the guide wheels 606 are in sliding contact with the surface of the workpiece, so that the staff can move the workpiece horizontally on the surface of the base 1, thereby facilitating continuous stamping of the plate. At the same time, when performing the stamping operation, the limiting motor 607 can be used to drive the positioning column 610 on the surface of the limiting frame 605 downward to press and limit the surface of the workpiece, thereby improving the stability of the workpiece during the stamping process and achieving the effect of convenient operation.

[0036] Through the above technical solution, a plurality of limiting guide holes 611 are opened on the surface of the limiting frame 605 . The size of the limiting guide holes 611 matches the positioning posts 610 , and the positioning posts 610 are slidably connected to the inner walls of the limiting guide holes 611 .

[0037] Working principle: First, place the automobile reinforcement plate on the surface of the base 1, and then use the dual-axis motor 12 to drive the driving rod 13 to rotate, and the driving rod 13 drives the driving gear 14 to rotate, and then drives the second transmission gear 10 and the transmission rod 8 to rotate, and at the same time drives the first transmission gear 9 and the driven gear 11 to rotate, and the driven gear 11 drives the linkage screw 4 to rotate, and then drives the two moving blocks 5 to move in the strip guide groove 3. The distance between the two limit frames 605 can be adjusted according to the width of the reinforcement plate, and then the lifting screw 603 is driven to rotate by rotating the adjusting nut 612, and then drives the adjusting block 60 4 moves downward in the rectangular adjustment slot 602, and at the same time drives the guide wheel 606 on the surface of the limit frame 605 to contact the surface of the reinforcing plate, thereby limiting and guiding the reinforcing plate, making it easier for the staff to move and feed the plate on the surface of the base 1. When the reinforcing plate is stamped, the limit motor 607 drives the limit screw 608 to rotate, and the limit screw 608 drives the lifting plate 609 to move downward, thereby driving a number of positioning columns 610 to move in the limit guide holes 611 on the surface of the limit frame 605. The positioning columns 610 are used to press against the surface of the reinforcing plate to limit the position, thereby improving the stability of the plate.
