Description

Technical Field

[0001] This utility model relates to the field of stamping, specifically to a novel multi-position stamping punch. Background Technology

[0002] Stamping is a processing method that uses pressure applied to metal sheets, strips, or tubes to induce plastic deformation or separation, thereby obtaining parts of the desired shape and size. Stamping is widely used in various fields such as automobiles, aerospace, home appliances, and instrumentation, and is an indispensable process in metal forming.

[0003] Existing punches, as disclosed in patent number 202420216918.9, are punches and stamping equipment that are easy to position. This punch has a channel in the middle of its base, and a mounting plate is installed inside the channel via a rotating shaft, allowing the user to quickly switch stamping blades by rotating the turntable. It is also fixed to the positioning assembly by a locking block on the outside of the base. However, its rotating shaft structure is easily deformed and damaged by impact forces during stamping. Furthermore, the locking block and positioning assembly protrude from both sides of the base, making them susceptible to interference from external environmental factors (such as dust and moisture), thus affecting their normal operation. Therefore, this invention proposes a novel multi-position stamping punch. Summary of the Invention

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] In this embodiment, refer to Figures 1-7The present invention relates to a novel multi-position stamping punch, comprising a base 1 and a cutter head assembly. The cutter head assembly includes a mounting plate 2 and several stamping cutters 4 arranged around the outside of the mounting plate 2, so that multiple stamping cutters 4 of different specifications can be integrated on one mounting plate 2, which facilitates quick switching between users and improves the versatility and flexibility of the equipment.

[0023] The mounting plate 2 has outwardly extending rotating shafts 6 on both sides, which are installed in the rails 7 inside the base 1. The lower end of the rails 7 is arc-shaped, and the rotating shafts 6 cooperate with the rails 7 to rotate, allowing the mounting plate 2 to rotate smoothly within the base 1.

[0024] Furthermore, the stamping cutter 4 is connected to the mounting plate 2 via threads. This threaded connection design makes the installation and removal of the stamping cutter 4 more convenient and efficient. Users can complete the installation or removal simply by rotating the stamping cutter 4, without the need for other tools, thus significantly improving the efficiency of replacing the stamping cutter 4. In addition, the stamping cutter 4 has a handle 5 in the middle. The handle 5 is rectangular or designed to provide a force-bearing surface for the operator, making it easy for the operator to rotate the stamping cutter 4, further improving the portability of assembly and disassembly.

[0025] Furthermore, a plurality of retractable ball bearings 10 are mounted on one side of the mounting plate 2 via a second spring 8. When the mounting plate 2 is rotated, the ball bearings 10 will automatically retract inward if they encounter any obstruction, ensuring that the normal operation of the mounting plate 2 is not hindered. The ball bearings 10 cooperate with the grooves 11 provided on the inner side of the base 1, and the position of the grooves 11 corresponds to the position where the cutter is fixed. Alternatively, the ball bearings 10 can be provided inside the base 1, and a plurality of grooves 11 can be provided on one side of the mounting plate 2. Whenever the stamping cutter 4 rotates to the predetermined position, the ball bearings 10 are ejected under the drive of the second spring 8 and precisely embedded in the grooves 11, realizing the pre-positioning function, thereby clearly indicating to the operator that the rotation has reached the predetermined position.

[0026] Furthermore, both ends of the rotating shaft 6 are provided with sliders 12. By setting a first spring 3 inside the rotating shaft 6 to abut against the sliders 12 on both sides, the sliders 12 on both sides can retract inward. The design of the first spring 3 ensures that the sliders 12 always maintain an outward pushing force, ensuring that the sliders 12 and the limiting grooves 13 are tightly fitted, and the sliders 12 can retract inward into the rotating shaft 6 by pressing.

[0027] Furthermore, the slider 12 is designed to be rectangular or have a shape that provides a limiting effect for the mounting plate 2. A limiting groove 13 is provided within the base 1 corresponding to the position of the slider 12, and the limiting groove 13 is set according to the shape and size of the slider 12. The mounting plate 2 is fixed under the limiting effect of the slider 12 and the limiting groove 13. The rectangular design significantly improves stability, effectively preventing the mounting plate 2 from rotating during the stamping process, and has excellent impact resistance. In addition, the opening edge of the limiting groove 13 adopts a chamfered design, which not only provides good guidance for the slider 12 but also facilitates the smooth entry of the slider 12 into the limiting groove 13.

[0028] Furthermore, knobs 14 are provided through both sides of the base 1. One end of each knob 14 is decorated with anti-slip texture, and the other end abuts against the slider 12. By pressing the knob 14 inward, it pushes the slider 12 inward, thereby releasing the limiting effect of the limiting groove 13 on the slider 12 and allowing the mounting plate 2 to rotate. In addition, the anti-slip texture design makes it easier for the operator to turn the knob 14.

[0029] Furthermore, the base 1 has L-shaped grooves 15 on both sides, and the knob 1414 has a locking pin 9 on the outside that engages with the L-shaped groove 15. By rotating the knob 14 and aligning the locking pin 9 with the opening of the L-shaped groove 15, the knob 14 can be pressed down. If the locking pin 9 is not aligned with the opening of the L-shaped groove 15, the knob 14 cannot be pressed down, thereby effectively preventing the mounting plate 2 from rotating accidentally due to accidental contact with the knob 14 during the stamping process, and further improving the stability and safety of the stamping process.

[0030] Furthermore, after pressing knob 14 to the bottom of L-shaped groove 15 and rotating it to one side, the locking pin 9 is fixed by the action of L-shaped groove 15, and knob 14 cannot spring back, ensuring that slider 12 is always in a compressed state. When both knobs 14 are pressed, knob 14 pushes slider 12 inward to retract and release slider 12 from fixing mounting plate 2, allowing mounting plate 2 to rotate smoothly. After mounting plate 2 rotates to the desired position, the operator only needs to rotate knob 14 in the opposite direction, and locking pin 9 will disengage from the limiting action of L-shaped groove 15. Under the action of spring force, slider 12 extends outward again, pushing knob 14 out and re-engaging with limiting groove 13, fixing mounting plate 2 and preventing it from rotating again, ensuring the stability and accuracy of the stamping process.

[0031] Furthermore, to facilitate operators in observing whether the knob 14 has been rotated to the correct position, the base 1 is provided with a mark that corresponds to the mark on the knob 14. Operators can determine whether the mounting plate 2 has been rotated to the correct position by observing whether the mark on the mounting plate 2 is aligned with the scale mark on the base 1.

[0032] The beneficial effects of this utility model are as follows: The mounting plate 2 is rotatably mounted on the base 1 via the rotating shaft 6, and several stamping blades 4 are arranged around the outer side of the mounting plate 2, allowing multiple different stamping blades 4 to be mounted simultaneously. Rotating the turntable allows for quick replacement of the stamping blades 4, significantly reducing blade change time. Furthermore, the mounting plate 2 is engaged with the limiting groove 13 via the slider 12, thus fixing the mounting plate 2 and preventing it from shifting during stamping, which could lead to a decrease in stamping accuracy. The limiting groove 13 is located inside the base 1, making the overall locking structure safer and more compact, reducing interference from external environmental factors.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
