Description

Technical Field

[0001] This utility model relates to the field of mold assembly technology, and in particular to a multi-directional positioning device for stamping dies. Background Technology

[0002] Stamping dies utilize a press to apply external force, causing sheet metal to separate or plastically deform within the die, thereby obtaining workpieces of the desired shape and size. They are widely used in the mass production of parts in industries such as automobiles, home appliances, and electronics.

[0003] Currently, commonly used stamping dies typically consist of an upper die, a lower die, guide components, and positioning devices. During the stamping process, the die is mounted on the press table, and the upper die moves downwards to press the sheet metal into the lower die cavity to achieve shearing, stretching, or forming. However, existing stamping die systems mostly adopt a fixed assembly structure, which is mainly suitable for standard-shaped or highly repetitive parts. When dealing with dies with significantly different external structures, existing positioning devices are difficult to be compatible, requiring frequent manual adjustments or replacements of positioning references during assembly. This not only affects positioning accuracy but also severely restricts the rapid changeover of dies and diversified production capabilities. Furthermore, differences in diameter, mounting hole positions, or guide structures between different dies limit the adaptability of existing tooling, making it difficult to achieve universal and efficient assembly and positioning requirements. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology is difficult to achieve rapid and accurate positioning and assembly of stamping dies of different diameters and sizes.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a multi-directional positioning device for stamping dies, including a machine base, a first stamping motor is fixedly installed on the sealing plate at the top of the machine base, a stamping plate is fixedly installed at the output end of the first stamping motor, a second stamping motor is fixedly installed at the bottom of the bottom layer of the machine base, a receiving plate is fixedly connected to its output end, and a protrusion is fixedly installed at the top of the receiving plate.

[0006] The top of the receiving plate is fastened with a cylindrical assembly cylinder, and the top and bottom of the assembly cylinder are connected through. An annular groove is opened on the top side of the assembly cylinder, and multiple moving blocks are slidably arranged in the annular groove. The moving blocks are fastened to the outside of the assembly cylinder. One end of the moving block is provided with a rib, and multiple assembly screw holes are provided through the rib. One end of the rib is fastened to the boss by bolts.

[0007] As a further improvement of this utility model, a horizontal plate is provided at the center of the machine platform, and a working square groove for the receiving plate and the stamping plate to fit together is opened at the center of the horizontal plate. Guide columns are fixedly provided on both sides of the horizontal plate, and the guide columns pass through both sides of the receiving plate and the stamping plate.

[0008] As a further improvement of this utility model, the top of the boss is provided with several screw holes, which are distributed around the top side of the boss along the axis, and the ends of the ribs are fastened to the boss by bolts.

[0009] As a further improvement of this utility model, the tail end of the moving block is threadedly connected to a limit bolt, and an assembly ring with a screw hole is fixedly provided on the outside of the assembly cylinder. The moving block is fastened to the assembly cylinder through the limit bolt and the assembly ring.

[0010] As a further improvement of this utility model, the bottom of the moving block is provided with a sliding groove that matches the annular groove.

[0011] As a further improvement of this utility model, a receiving seat is fixedly provided at the top of the receiving plate, and the receiving seat is fitted and connected to the bottom end of the assembly cylinder.

[0012] The beneficial effects of this invention are as follows: A stamping die with a screw hole at the bottom is placed on the ribs of the assembly cylinder. The pre-set array of screw holes on the ribs allows for quick matching of the installation requirements of dies with different diameters. Initial fixing is achieved by screwing in bolts from the bottom. To address the poor adaptability of existing technologies to dies of different sizes, this device features a specially designed movable block that can slide freely along the annular groove and slide rail. By adjusting the position of the movable block to precisely align it with the screw hole at the bottom of the die, flexible radial position adjustment is achieved, ensuring accurate positioning of dies of various specifications. To further enhance assembly stability, a limiting bolt is provided at the tail end of the movable block. Through threaded engagement with the assembly ring, a lateral constraint is formed, effectively preventing die displacement during operation. After the ribs and the boss are fastened with bolts, a radial multi-locking structure is formed. Attached Figure Description

Guide posts 11 are fixedly installed on both sides of the horizontal plate, and the guide posts 11 pass through both sides of the receiving plate 3 and the stamping plate 2 to provide guidance for the receiving plate 3 and the stamping plate 2.

[0023] As attached Figure 3 , 4 As shown, a cylindrical assembly cylinder 5 is fastened and fitted to the top of the receiving plate 3. The assembly cylinder 5 is used to fasten mold plates of different diameters. A receiving seat 15 is fixedly installed at the top of the receiving plate 3, and the receiving seat 15 is fitted and connected to the bottom of the assembly cylinder 5 to ensure a reliable connection between the assembly cylinder 5 and the receiving seat 15. The top and bottom of the assembly cylinder 5 are connected through each other. An annular groove 6 is opened on the top side of the assembly cylinder 5, and multiple moving blocks 7 are slidably arranged in the annular groove 6. The bottom of the moving block 7 is provided with a sliding groove 14 that matches the annular groove 6 to facilitate sliding guidance. The moving block 7 is fastened and connected to the outside of the assembly cylinder 5. A rib 8 is provided at one end of the moving block 7, and multiple assembly screw holes are provided through the rib 8. One end of the rib is fastened and assembled to the boss 9 by bolts.

[0024] As attached Figure 3 , 4 As shown, the top of the boss 4 has several screw holes distributed around the top side of the boss 4 along the axis, and the ends of the ribs 8 are fastened to the boss 4 by bolts. At the other end, the tail end of the moving block 7 is threadedly connected to a limit bolt 12, and an assembly ring 13 with screw holes is fixedly provided on the outside of the assembly cylinder 5.
