Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, specifically to a high-strength improved punch. Background Technology

[0002] Stamping, an indispensable process in modern manufacturing, is widely used in the forming and punching of metal and structural parts. As a core component of stamping dies, the punch's performance directly affects processing efficiency, part accuracy, and die lifespan. Under harsh conditions such as continuous stamping and processing of high-strength materials, higher requirements are placed on the punch's strength, wear resistance, and reliability.

[0003] The punch of a stamping machine usually adopts an integral structure and is rigidly installed on the die base or upper die fixing plate through interference fit, threaded connection or pressure plate fixing. When performing stamping operation, the operator needs to remove the elastic stripper plate and other components of the die first, and use a special wrench to loosen the fixing bolts.

[0004] The existing punch replacement process is cumbersome and time-consuming, which seriously affects the speed of equipment mold changing when changing materials on the production line. Furthermore, the single fixed punch structure limits the process flexibility of the mold, making it difficult to quickly switch between different hole diameters and shapes, which affects the utilization rate of the equipment. At the same time, frequent disassembly and assembly operations can easily lead to thread damage or decreased fitting accuracy of the punch fixing parts, resulting in a shortened service life of the mold. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a high-strength improved punch that can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a high-strength improved punch, including a connecting seat, with connecting plates fixed on both sides of the bottom of the connecting seat, and a connecting shaft fixed on the bottom of the two connecting plates on opposite sides. A rotating ring is rotatably connected to the outside of the connecting shaft, and a connecting block is fixed on the outer wall of the rotating ring. A threaded rod is fixed on the side of the connecting block away from the rotating ring, and a support ring is fixed on the outer wall of the threaded rod near the connecting block. A punch mechanism is provided on the outer wall of the threaded rod, and a limit mechanism is provided on one side of the outer wall of one of the connecting plates.

[0008] Furthermore, the punch mechanism includes a threaded section, which is threadedly connected to the threaded rod and abuts against the support ring.

[0009] Furthermore, a connecting section is fixed to one end of the threaded section, an impact section is fixed to one end of the connecting section, and an arc-shaped groove is provided at the connection between the connecting section and the impact section.

[0010] Furthermore, four connecting blocks are provided, and the four connecting blocks are arranged in a circumferentially equidistant manner.

[0011] Furthermore, the limiting mechanism includes a limiting shaft, which is fixed to one side of the outer wall of the connecting plate. The limiting shaft is T-shaped, and a spring is movably sleeved on the outside of the limiting shaft. A movable collar is movably sleeved on the outer wall of the limiting shaft, and one side of the movable collar is fixed to one end of the spring.

[0012] Furthermore, a connecting ring is fixed to the outer wall of the movable collar, and a limiting rod is fixed to the side of the connecting ring near the connecting plate. Multiple limiting rods are provided, and the multiple limiting rods are arranged in a circumferentially equidistant manner. The limiting rods are movably connected to the connecting plate.

[0013] Furthermore, a limit hole is provided through one side of the rotating ring, and multiple limit holes are provided. The multiple limit holes are used in conjunction with multiple limit rods, and a protective sleeve is fixed on the other side of the connecting ring.

[0014] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0015] 1. This application pre-installs four commonly used punch mechanisms. When different punch mechanisms need to be replaced for stamping, the protective sleeve is pinched and stretched outwards, the spring is compressed, and the limit rod slides out of the limit hole. Then, the position of the punch mechanism can be adjusted by rotating the rotating ring outside the connecting shaft. After adjustment, the protective sleeve is released, and multiple limit rods pass through the connecting plate and are inserted into the limit hole to limit the rotating ring, which effectively improves the equipment utilization rate and production efficiency.

[0016] 2. This application features an arc-shaped groove between the impact section and the connecting section of the punch mechanism. The depth of the groove is adapted to the material thickness, which can effectively reduce the material pulling force after stamping, reduce the risk of jamming and chip jumping. The structure of the support ring and the threaded rod provides reliable support for the punch mechanism during the stamping process, disperses the impact stress, and prevents the threaded connection from loosening or being damaged, thereby reducing production interruptions and mold maintenance frequency, and extending the service life of the punch.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0026] This application discloses a high-strength improved punch, including a connecting seat 1, connecting plates 2 fixed on both sides of the bottom of the connecting seat 1, a connecting shaft 3 fixed on the bottom of the opposite side of the two connecting plates 2, a rotating ring 4 rotatably connected to the outside of the connecting shaft 3, a connecting block 6 fixed on the outer wall of the rotating ring 4, a threaded rod 7 fixed on the side of the connecting block 6 away from the rotating ring 4, a support ring 8 fixed on the outer wall of the threaded rod 7 near the connecting block 6, a punch mechanism 10 provided on the outer wall of the threaded rod 7, and a limit mechanism 90 provided on one side of the outer wall of one of the connecting plates 2.

[0027] Reference Appendix Figure 4The punch mechanism 10 includes a threaded section 101, which is threadedly connected to the threaded rod 7 and abuts against the support ring 8. The punch mechanism 10 is connected to the threaded rod 7 through the threaded section 101, enabling the rapid replacement of the impact section 103. The support ring 8 supports the threaded section 101 to prevent the threaded section 101 and the threaded rod 7 from being damaged during subsequent impacts.

[0028] Reference Appendix Figure 4 One end of the threaded section 101 is fixed with a connecting section 102, and the other end of the connecting section 102 is fixed with an impact section 103. An arc-shaped groove 104 is provided at the connection between the connecting section 102 and the impact section 103. The top of the impact section 103, which is arc-shaped, reduces the material pulling force after impact and reduces the occurrence of material jamming. The corresponding punch mechanism 10 is selected according to the thickness of the material. The arc-shaped groove 104 needs to be greater than two-thirds of the material thickness to reduce the risk of chip jumping.

[0029] Reference Appendix Figure 2 There are four connecting blocks 6, which are arranged in a circumferentially equidistant manner. With four connecting blocks 6, four commonly used punch mechanisms 10 can be pre-installed. When it is necessary to change to different punch mechanisms 10 for stamping, the position of the punch mechanism 10 can be adjusted by rotating the rotating ring 4 outside the connecting shaft 3. When the punch mechanism 10 is stamping, the support ring 8 provides support, and at the same time, the rotating ring 4 presses the connecting shaft 3 for synchronous support.

[0030] Reference Appendix Figure 2 The limiting mechanism 90 includes a limiting shaft 91, which is fixed to one side of the outer wall of the connecting plate 2. The limiting shaft 91 is T-shaped. A spring 92 is movably sleeved on the outside of the limiting shaft 91. A movable collar 93 is movably sleeved on the outer wall of the limiting shaft 91. One side of the movable collar 93 is fixed to one end of the spring 92. The movable collar 93 can move on the limiting shaft 91. When there is no external force, the spring 92 pushes the movable collar 93 to fit against the connecting plate 2.

[0031] Reference Appendix Figure 1 , 2 In section 3, a connecting ring 94 is fixed to the outer wall of the movable collar 93. A limit rod 96 is fixed to the side of the connecting ring 94 near the connecting plate 2. Multiple limit rods 96 are provided, and the multiple limit rods 96 are arranged in a circumferentially equidistant manner. The limit rods 96 are movably connected to the connecting plate 2. A limit hole 5 is provided through one side of the rotating ring 4. Multiple limit holes 5 are provided and are used in conjunction with multiple limit rods 96. A protective sleeve 95 is fixed to the other side of the connecting ring 94. By having multiple limit rods 96 pass through the connecting plate 2 and insert into the limit holes 5, the rotating ring 4 is limited to prevent it from rotating arbitrarily during stamping. The use of multiple limit rods 96 and limit holes 5 makes the limiting of the rotating ring 4 more tight, preventing excessive stamping pressure from causing deformation of a single limit rod 96.

[0032] The workflow of this utility model is as follows:

[0033] First, connect the connecting seat 1 to the stamping machine. When using, select the appropriate punch mechanism 10 according to the material to be stamped. The arc groove 104 must be greater than two-thirds of the material thickness. Pre-install the four commonly used punch mechanisms 10. Connect the punch mechanism 10 to the threaded rod 7 via the threaded section 101 to achieve quick replacement of the impact section 103. Support ring 8 supports the threaded section 101 to prevent damage to the threaded section 101 and threaded rod 7 during subsequent impacts. When it is necessary to change to a different punch mechanism 10 for stamping, pinch the protective sleeve 95 with your fingers and pull it outwards. The spring 92 will compress, and the limiting rod 96 will exit from the limiting hole 5. Slide out, and then rotate the rotating ring 4 outside the connecting shaft 3 to adjust the position of the punch mechanism 10. After adjustment, loosen the protective sleeve 95. When there is no external force, the spring 92 pushes the moving collar 93 to fit with the connecting plate 2. Multiple limit rods 96 pass through the connecting plate 2 and are inserted into the limit hole 5 to limit the rotating ring 4, preventing the rotating ring 4 from rotating randomly during stamping. The use of multiple limit rods 96 and limit holes 5 makes the limiting of the rotating ring 4 more tight, preventing excessive stamping pressure from causing deformation of a single limit rod 96. Then, stamping can be carried out directly. The top of the arc-shaped impact section 103 reduces the material pulling force after the impact and reduces the occurrence of material jamming.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
