Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically to a micro-punching mechanism. Background Technology

[0002] Stamping dies are equipment used in cold stamping processes to shape materials. When processing products with stamping dies, a small number of the same product may require side holes. Currently, this is addressed by developing a new stamping die, which increases the cost of die development. Therefore, there is an urgent need to design a micro-punching mechanism to solve this problem. Utility Model Content

[0003] The purpose of this invention is to provide a micro-punching mechanism to address the aforementioned shortcomings in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A miniature punching mechanism includes a main body block with a mating opening inside the main body block. A punching block is inserted into the mating opening. One end of the punching block is provided with a bevel. An insertion interface is provided on the top outer wall of the main body block. A drive block is inserted into the insertion interface. A stop block is integrally formed on the top outer wall of the punching block. A spring is provided on one side of the stop block.

[0006] Furthermore, the top inner wall of the mating port is provided with a placement groove, and the stop block and the spring are both located inside the placement groove.

[0007] Furthermore, a second inclined surface is provided on one side of the bottom of the drive block, which is adapted to the first inclined surface.

[0008] Furthermore, a baffle is fixed inside the main block, and the baffle is located on the side of the block away from the spring.

[0009] Furthermore, a mating groove is formed on one side of the outer wall of the main body block, the baffle is located inside the mating groove, and evenly distributed countersunk holes are formed on one side of the outer wall of the main body block.

[0010] In the above technical solution, the micro punching mechanism provided by this utility model has the following advantages: by extruding the driving block, the driving block can extrude the punching block and make it extend out of the mating opening, thereby achieving the effect of punching holes on the side of the formed product. This eliminates the need to redevelop the mold when punching the product, thus saving the cost of mold development. Attached Figure Description

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] like Figure 1-4 As shown, the miniature punching mechanism provided in this embodiment of the present invention includes a main body block 1, a mating opening 2 inside the main body block 1, a punching block 3 inserted into the mating opening 2, a bevel 6 at one end of the punching block 3, an insertion interface 12 on the top outer wall of the main body block 1, a driving block 7 inserted into the insertion interface 12, a stop block 11 integrally formed on the top outer wall of the punching block 3, and a spring 5 on one side of the stop block 11.

[0020] Specifically, in this embodiment, a main body block 1 is included. In use, only slight modifications are needed to the existing mold to provide a position for the main body block 1. The main body block 1 is then installed on the existing stamping die. The main body block 1 has a mating opening 2, into which a punching block 3 is inserted. The punching block 3 is made of high-hardness metal material and serves to perform side punching on the product. A punching opening matching the punching block 3 needs to be machined into the existing mold. One end of the punching block 3 has a bevel 6. The top of the main body block 1... The outer wall of the part has an insertion interface 12, and a drive block 7 is inserted into the inside of the insertion interface 12. The insertion interface 12 is connected to the mating port 2. When in use, the drive block 7 is driven by a hydraulic device. A second inclined surface 8 is provided on one side of the bottom of the drive block 7. The second inclined surface 8 is adapted to the first inclined surface 6 to squeeze the drive block 7, so that the punching block 3 can extend out from the mating port 2, thereby completing the side hole punching of the product. A stop block 11 is integrally formed on the top outer wall of the punching block 3. A spring 5 is provided on one side of the stop block 11. The spring 5 has the effect of resetting the punching block 3.

[0021] The micro punching mechanism provided by this utility model installs the main body block 1 on the original stamping die. After the product is formed, the driving block 7 is squeezed, and the driving block 7 can squeeze the punching block 3 and make it extend out of the mating port 2, thereby achieving the effect of punching holes on the side of the formed product. This eliminates the need to redevelop the mold when punching the product, thus saving the cost of mold development.

[0022] In another embodiment of this utility model, a placement groove 4 is provided on the top inner wall of the mating port 2. The stop block 11 and the spring 5 are both located inside the placement groove 4. When the driving block 7 does not press the punching block 3, the spring 5 can push the stop block 11 and the punching block 3 to reset, so that the punching block 3 retracts into the mating port 2.

[0023] In another embodiment of this utility model, a baffle 10 is fixed inside the main body block 1. The baffle 10 is located on the side of the stop block 11 away from the spring 5. The baffle 10 seals the other side of the mating port 2 to prevent dust from entering. A mating groove 9 is opened on one side of the outer wall of the main body block 1. The baffle 10 is located inside the mating groove 9. The baffle 10 is fixed inside the mating groove 9, making the overall appearance structure more regular and avoiding interference with the original mold operation. A countersunk hole 13 is evenly distributed on one side of the outer wall of the main body block 1. The countersunk hole 13 is the process hole for the installation of the main body block 1 and the original mold.

[0024] Working principle: When in use, the main body block 1 is installed on the stamping die. When the side hole needs to be punched after the product is stamped, the drive block 7 is squeezed, so that the drive block 7 squeezes the inclined surface 6 of the punching block 3 through the inclined surface 8. This causes the punching block 3 to extend out of the main body block 1 and punch the side hole of the product. After the side hole is punched, the pressure on the drive block 7 is released, and the elastic force of the spring 5 pushes the stop block 11, so that the stop block 11 drives the punching block 3 to retract into the mating opening 2.

[0025] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
