Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, specifically to a tooling and fixture for metal stamping. Background Technology

[0002] In the metal stamping process, tooling fixtures play a crucial role. They are used to fix and position metal parts to ensure the accuracy and quality of stamping. Traditional tooling fixtures for metal stamping usually adopt simple mechanical structures, such as bolt fastening and pressure plate clamping, to fix the metal parts.

[0003] A search revealed a patent, CN212216861U, which discloses a tooling fixture for stamping metal parts. The fixture includes a support base plate and a bearing plate. A clamping platform is rotatably mounted on the support base plate. The bearing plate is fixed above the clamping platform by multiple support rods. Four externally threaded posts are symmetrically mounted on the clamping platform. Movable seats are threaded between two symmetrically positioned externally threaded posts. Two clamping assemblies are located between the two movable seats. Multiple telescopic rods are equidistantly arranged from front to back on the opposite end faces of the two movable seats. The ends of the telescopic rods furthest from the movable seats are fixedly connected to the adjacent clamping assemblies. This fixture has an adjustable structure, allowing for flexible adjustment according to the actual size of the metal parts. It is suitable for irregular metal parts, can quickly and stably clamp metal parts, is simple to operate, convenient to use, and highly practical.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-6 A tooling fixture for stamping metal parts includes a stamping main unit 1, and a matching lower stamping carrier 2 and an upper stamping carrier 3. The lower stamping carrier 2 is fixedly installed on the upper part of the stamping platform of the stamping main unit 1, and the upper stamping carrier 3 is fixedly installed at the lower end of the stamping telescopic device on the stamping main unit 1. The upper part of the lower stamping carrier 2 is provided with a placement platform 4 that matches the upper stamping carrier 3. The bottom of the placement platform 4 is provided with a forming groove 5 that matches the lower part of the upper stamping carrier 3. The placement platform 4 is provided with a plurality of positioning plates 6 that match the number of sides of the lower stamping carrier 2. A plurality of through-holes are fixedly installed on one side of the positioning plates 6. The moving column 7 passes through the lower stamping carrier 2. Several moving columns 7 extend one end to the outside of the lower stamping carrier 2 and are fixedly installed with a first extrusion block 8 between the ends. The side of the moving column 7 is fitted with an elastic element 9 located between the first extrusion block 8 and the lower stamping carrier 2. The first extrusion block 8 is provided with a first extrusion angle 10 on one side. The upper stamping carrier 3 is provided with a second extrusion block 11 on multiple sides that is adapted to the first extrusion block 8. The second extrusion block 11 is provided with a second extrusion angle 12 on one side that is adapted to the first extrusion angle 10. The positioning plate 6 is adapted to the number of edges, side shape and thickness of the workpiece to be stamped.

[0028] Specifically, when stamping a metal part, a lower stamping carrier 2, with dimensions matching the metal part, is fixedly installed on the stamping table of the stamping host 1. An upper stamping carrier 3 is fixedly installed at the lower end of the stamping telescopic device on the stamping host 1. The positions of the lower stamping carrier 2 and the upper stamping carrier 3 are calibrated and fixed. During stamping, the metal part is placed on the placement table 4, positioned between several positioning plates 6. The stamping telescopic device on the stamping host 1 is activated, causing the upper stamping carrier 3 to move downwards. As the upper stamping carrier 3 moves downwards, several second extrusion blocks 11 are moved downwards. Before the upper stamping carrier 3 contacts the metal part, the second extrusion angle 12 on the second extrusion block 11 contacts the first extrusion angle 10 on the first extrusion block 8. The upper stamping carrier 3 continues to move downwards, and the second extrusion angle 12 presses against the first extrusion angle 10, pushing the moving column 7 to move. At this time, the elastic element 9 is compressed. The elastic element 9 is a spring. The moving column 7 drives the positioning plate 6 to move. Several positioning plates 6 move towards each other, and the positioning plates 6 are clamped at the side of the metal part. Furthermore, the metal part is centered and positioned. After the second extrusion angle 12 passes the position of the first extrusion angle 10, the second extrusion block 11 can no longer extrude the first extrusion block 8. The upper stamping carrier 3 continues to move downwards, and through the cooperation of its lower protrusion position with the forming groove 5, the stamping of the metal part is completed. After the stamping is completed, the upper stamping carrier 3 moves upwards. At this time, the tension of the elastic element 9 pushes the first extrusion block 8 away from the stamping host 1. Several positioning plates 6 release the metal part, and the stamped metal part can be taken out. Among them, the lower stamping carrier 2 contains The shape of the placement platform 4 is adapted to the shape of the metal part, the number of positioning plates 6 is equal to the number of edges of the metal part, the shape of the positioning plates 6 is adapted to the edge shape of the metal part, and the thickness of the positioning plates 6 is adapted to the metal part. In specific operation, it is only necessary that the positioning plates 6 do not affect the stamping of the metal part. By moving the upper stamping carrier 3 downward, and through the cooperation of the second extrusion block 11 and the first extrusion block 8, several positioning plates 6 are pushed to move towards each other, so as to center and position the metal part and clamp and fix it, thereby improving the stamping accuracy of the stamping device.

[0029] As a technical optimization of this utility model, the upper stamping carrier 3 has fixed seats 13 adapted to the second extrusion block 11 fixedly installed on multiple sides. Adjusting blocks 14 for adjusting the horizontal position of the first extrusion block 8 are slidably connected to the fixed seats 13. Adjusting grooves 15 adapted to the adjusting blocks 14 are opened through the upper and lower sides of the fixed seats 13. A threaded post 16 is fixedly installed on the upper part of the adjusting block 14. A first limiting nut 17 for fixing the position of the adjusting block 14 is threadedly connected to the side of the threaded post 16. The adjustment block 14 is provided with an adjusting threaded rod 18 that passes through the threaded post 16 and is threadedly connected to the adjusting block 14. The lower end of the adjusting threaded rod 18 is rotatably connected to the upper part of the second extrusion block 11. The side of the adjusting threaded rod 18 is threadedly connected with a second limiting nut 19 for limiting the adjusting threaded rod 18. The fixed base 13 is fixedly installed with side plates 20 that are adapted to it on opposite sides. The upper part of the second extrusion block 11 is fixedly installed with two limiting rods 21 that pass through the side plates 20. The side plates 20 are provided with limiting grooves 22 that are adapted to the limiting rods 21.

[0030] Specifically, the horizontal position of the second extrusion block 11 can be adjusted by sliding the adjusting block 14 within the adjusting groove 15. After the position of the second extrusion block 11 is adjusted, the first limiting nut 17, which is threaded onto the side of the threaded post 16, is tightened to limit the position of the adjusting block 14. When adjusting the horizontal position of the second extrusion block 11, the limiting rod 21 moves within the upper limiting groove 22 of the side plate 20, thus limiting the position of the second extrusion block 11. When the height of the second extrusion block 11 needs to be adjusted, the adjusting threaded rod 1 is rotated. 8. When the adjusting threaded rod 18 rotates, it drives the second extrusion block 11 to move. After the height position of the second extrusion block 11 is adjusted, the second limiting nut 19, which is threaded to the side of the adjusting threaded rod 18, is locked. The second limiting nut 19 abuts against the upper part of the threaded post 16 to limit and fix the position of the adjusting threaded rod 18. This allows for adjustment of the horizontal and height positions of the second extrusion block 11, thereby adjusting the magnitude of the extrusion movement of the first extrusion block 8. It can adjust different sizes and clamping tightness, thus improving the applicability of this tooling fixture.

[0031] As a technical optimization of this utility model, guide angles 23 are provided on the upper part of the facing sides of several positioning plates 6. The guide angles 23 are adapted to the lower part of the upper stamping carrier 3 and are used to guide the upper stamping carrier 3 as it moves downward. Mounting plates 24 are fixedly installed on multiple sides of the stamping host 1. The mounting plates 24 are fixedly installed on the stamping table of the stamping host 1 with bolts, which facilitates the installation or replacement of the lower stamping carrier 2. At the same time, the upper stamping carrier 3 can also be replaced.

[0032] Among them, the above-mentioned stamping host 1 is existing technology, which is a mature technology and has been fully disclosed. Therefore, it will not be repeated in the specification. All the electrical products mentioned above are equipped with power connection cords, and they are electrically connected to the external main controller and 220V phase voltage (or 380V line voltage) through the power cords. The main controller can be a conventional known device such as a computer that plays a control role.
