Technical Field

[0001] This utility model mainly relates to the field of quick-release lock pin processing technology, specifically to a stamping device for quick-release lock pin processing. Background Technology

[0002] Quick-release fasteners are widely used in aerospace, automotive, and machinery industries, characterized by their ease of installation and rapid disassembly. The nut portion of a quick-release fastener typically needs to be stamped into a flared shape to ensure good locking performance and resistance to loosening during use. However, there are currently few specialized stamping tools available on the market for forming quick-release fastener nuts, and existing equipment is generally expensive and complex to operate, making it difficult to meet the needs of small and medium-sized enterprises and individual users.

[0003] Most existing stamping devices rely on electric or pneumatic drives. Although they have a high degree of automation, they are not very suitable for situations where there is no power supply or where flexible operation is required, such as field operations or small-batch production. Therefore, there is an urgent need for a quick-release locking pin processing device that is simple in structure, low in cost, easy to operate manually, and provides stable stamping results to overcome the shortcomings of existing technologies.

[0025] See attached document Figure 1-7A stamping device for processing quick-release lock studs includes a stamping base 1, with a stamping table 2 vertically connected to the rear end of the stamping base 1. A lifting sliding part 3 is slidably connected to the stamping table 2. A receiving groove is provided at the bottom of the lifting sliding part 3, and a hollow stamping head 4 is detachably installed at the bottom of the receiving groove. A positioning groove 5 is provided on the side of the hollow stamping head 4, and a locking screw 6 is threadedly connected to the side wall of the receiving groove. The locking screw 6 passes through the side wall of the lifting sliding part 3 and is engaged in the positioning groove 5 to fix the hollow stamping head 4. The top of the stamping base 1 is used to place the quick-release lock stud, and the top of the quick-release lock stud abuts against a stamping template 7. The bottom of the stamping template 7 is supported at the nut of the quick-release lock stud, and a trumpet-shaped stamping groove is provided at the top. The hollow stamping head 4 is aligned with the stamping template 7 by pressing down, and the outer side of the nut of the quick-release lock stud is stamped into a trumpet-shaped structure. In this embodiment, the worker first places the quick-release lock stud to be stamped. Place the quick-release screw at the preset position on top of the stamping base 1, then fit the stamping template 7 onto the top of the quick-release screw, ensuring that the central axis of the quick-release screw is collinear with the central axis of the hollow stamping head 4. Select a matching hollow stamping head 4 according to the specifications of the quick-release screw, and embed it into the receiving groove at the bottom of the lifting sliding part 3. Tighten the locking screw 6 on the side wall of the receiving groove so that the end of the screw is engaged in the positioning groove 5 on the side of the hollow stamping head 4, thereby achieving radial limiting of the hollow stamping head 4. Move the handle of the stamping table 2 downward to drive the lifting sliding part 3 to press down in the vertical direction, so that the hollow stamping head 4 and the stamping template 7 work together to cold forge the head of the quick-release screw into a trumpet-shaped structure, completing the stamping operation. This device has a simple structure, and the detachable hollow stamping head 4 can be used for stamping operations of quick-release screws of different specifications. The stamping table 2 adopts a manual stamping device, which is existing technology and will not be described in detail here. The overall structure is simple, easy to carry, and suitable for small batch workpiece processing operations.

[0026] An annular rubber pad is provided in the contact area between the end of the locking screw 6 and the side wall of the positioning groove 5. The annular rubber pad is vulcanized and covered on the end of the locking screw 6 to increase the static friction coefficient between the hollow punch head 4 and the locking screw 6, thereby improving the stability of the hollow punch head 4 during operation.

[0027] Please refer to this carefully. Figure 2 The stamping base 1 has multiple threaded holes 12 on its top. A detachable positioning plate 11 is fixed to the threaded holes 12 by bolts. The top of the positioning plate 11 has a limiting groove adapted to the shape of the quick-release screw to limit the horizontal displacement of the quick-release screw. In this embodiment, a detachable positioning plate 11 is provided. During installation, it is fixed to the limiting groove by bolts to quickly position the quick-release screw and ensure the accuracy of subsequent stamping. The limiting groove limits the bottom of the quick-release screw, and the positioning plate 11 can also be replaced according to the specifications of the quick-release screw.

[0028] The stamping base 1 has three threaded holes 12 arranged in a triangle on its top. This embodiment provides a specific design for the threaded holes 12. The triangular structure has stability and can better position the stamping base 1.

[0029] Please refer to this carefully. Figure 2 and Figure 3 The bottom four corners of the lifting sliding part 3 are fixedly connected to guide sleeves 31. The upper ends of the four vertical telescopic columns 32 are slidably inserted into the guide sleeves 31 by springs, and the lower ends are detachably connected to the stamping template 7. In this embodiment, the initial height of the stamping template 7 is higher than the quick-release lock pin placement position. After being pressed, it drives the telescopic columns 32 to retract into the guide sleeve. In order to facilitate the rapid stamping of the stamping template 7, the stepped guide groove at the bottom of the stamping template 7 automatically fits into the head of the quick-release lock pin to achieve center alignment. The lifting force of the quick-release lock pin causes the telescopic columns 32 to retract, compressing the spring to store energy and continue to press down the lifting sliding part 3. The hollow stamping head 4 contacts the stamping template 7. The spring pressure maintains the tight fit between the template and the workpiece, and together they complete the trumpet-shaped stamping. After releasing the handle, the spring pushes the telescopic columns 32 to extend, and the stamping template 7 automatically returns to the initial height. There is no need to manually place the stamping template 7 each time, which improves the stamping efficiency.

[0030] The hollow punch head has four parts made of mold steel. Mold steel has the advantages of high hardness, wear resistance and compressive strength, which ensures that the punch has a long service life. It should be noted that the integral punch can also be made of other materials.

[0031] The positioning groove 5 can be a cuboid groove or a cylindrical groove. The appropriate positioning groove 5 can be opened according to the situation to accurately position the punch when it is installed. The cylindrical groove is easy to cooperate with the locking screw 6 to improve the stability of the punch during installation. The cuboid groove is easy to manufacture and reduces costs.

[0032] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
