Background Art

A stamping die is a process equipment used for cold stamping. It can process metal or non-metal materials into parts or semi-finished products. At room temperature, a die installed on a press is used to apply pressure to the material to separate or plastically deform it, thereby obtaining the desired parts. A stamping die is a special process equipment and an important part of industrial production. During the use of the stamping die, the die needs to be fixed in an appropriate position to ensure the accuracy and stability of the processing.

However, the existing stamping die clamping devices often cannot meet the clamping requirements of dies of different sizes and shapes, and are complicated to operate and inefficient, making it difficult to meet the needs of modern industrial production. For this reason, we propose an adjustable clamping device on the stamping die.

Please refer to Figures 1-4, an adjustable clamping and fixing device on a stamping die includes a die base 1, a fixing device 2 is provided on the side of the die base 1, an annular groove is provided on the upper surface of the die base 1, a plurality of rolling steel balls 10 are movably clamped in the annular groove, a mounting circular plate 3 is attached to the top of the plurality of rolling steel balls 10, a rotating column 9 is fixedly connected to the lower surface of the mounting circular plate 3, the rotating column 9 is movably plugged into the upper surface of the die base 1, eight square slide grooves 4 arranged equidistantly in a ring are provided on the upper surface of the mounting circular plate 3, and a clamping and fixing device 5 is provided above the eight square slide grooves 4.

Furthermore, the fixing device 2 includes a mounting box 6 and a plug 7. The mounting box 6 is fixedly connected to the lower part between the two square slide grooves 4 corresponding to the top of the side surface of the mold base 1. The mounting box 6 is provided with a plug slot, and a plug 7 is movably connected in the plug slot. A spring is fixedly connected between the bottom of the plug 7 and the inner wall of the bottom of the plug slot. A fixed socket 8 is provided on the lower surface of the mounting circular plate 3 corresponding to the top of the plug 7.

Furthermore, the side surface of the mounting circular plate 3 is threadedly connected with eight circularly equidistantly arranged threaded push-pull rods 18, which extend into the inner cavity of the square slide groove 4 and are movably inserted into the inner wall of the square slide groove 4 on the side away from the outer ring of the mounting circular plate 3. The inner cavity of the square slide groove 4 on the threaded push-pull rod 18 is threadedly connected with a movable sleeve 11, and the movable sleeve 11 is movably clamped in the square slide groove 4.

Furthermore, the clamping and fixing device 5 includes a movable base plate 12, a mounting seat 13, a clamping plate 14 and a threaded telescopic rod 15. The top of the movable sleeve 11 is fixedly connected to the movable base plate 12, the upper surface of the movable base plate 12 is fixedly connected to the mounting seat 13, the side of the mounting seat 13 close to the threaded push-pull rod 18 is threadedly connected to the threaded telescopic rod 15, the threaded telescopic rod 15 extends to the other end of the mounting seat 13 and is fixedly connected to the clamping plate 14. The movable base plate 12 is used to conduct the pulling force brought by the movable sleeve 11, driving the upper device to approach the workpiece, and the workpiece can be clamped by rotating the threaded telescopic rod 15 to push 14.

Furthermore, the clamping and fixing device 5 also includes a support member 16, a support member 2 17 and a connecting block 19. Two symmetrically distributed connecting blocks 19 are fixedly connected to both ends of the side of the mounting seat 13 close to the clamping plate 14. A support member 16 is rotatably connected between two adjacent connecting blocks 19. The other ends of the two support members 16 are rotatably connected to two support members 2 17 at the upper and lower ends. The end of the support member 2 17 away from the support member 16 is hinged on the side of the clamping plate 14 close to the mounting seat 13. The support members 16 and the support members 2 17 can ensure that the clamping plate 14 will not shake left and right when the threaded telescopic rod 15 rotates, thereby ensuring the stability of the clamping.

Furthermore, the side of the clamping plate 14 away from the second support member 17 is a rough surface. The rough surface allows the clamping plate 14 to have greater friction when clamping the workpiece, thereby ensuring the stability of the clamping.

Working principle: When the device is required to clamp the workpiece during stamping, one or more clamping and fixing devices 5 are selected according to the shape of the workpiece, and the threaded push-pull rod 18 below is rotated. The movable sleeve 11 is pushed toward the center in the square slide groove 4 through threaded transmission by rotating the threaded push-pull rod 18. When the movable sleeve 11 moves, it drives the clamping and fixing device 5 above to move toward the center. When it moves to a position close to the workpiece, the threaded telescopic rod 15 at one end of the rotating mounting seat 13 is rotated. The threaded telescopic rod 15 is rotated in the mounting seat 13 so that the other end of the threaded telescopic rod 15 pushes the clamping plate 14 to clamp the workpiece. The support members 16 and 17 on both sides of the threaded telescopic rod 15 can ensure that the clamping plate 14 will not be when the threaded telescopic rod 15 rotates. The workpiece can be processed by the plurality of clamping and fixing devices 5 selected according to the shape of the workpiece after completing the clamping of the workpiece through the above operation. During the processing, if the workpiece needs to be rotated, the plug 7 in the fixing device 2 can be pulled out from the fixing socket 8, and the bottom of the plug 7 can be clamped in the plug slot provided in the mounting box 6. Then, by rotating the mounting circular plate 3, the workpiece at the center of the upper surface of the mounting circular plate 3 can be driven to rotate, which can meet different processing requirements. The rolling steel balls 10 in the annular groove on the upper surface of the mold base 1 can not only provide support for the mounting circular plate 3, but also reduce the friction force when the mounting circular plate 3 rotates, reduce the wear of the mounting circular plate 3, and extend the service life of the equipment.

Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
