Abstract
Description
Technical Field
[0001] This utility model belongs to the field of positioning structure technology, specifically a positioning structure for a punching die tool. Background Technology
[0002] Traditional punching die positioning methods typically involve using positioning screws for fixing. Threaded holes are made in the base plate, and the positioning screws are installed in the threaded holes to fix the cutter. However, during long-term punching, the threaded holes may deform and expand due to punching pressure or vibration. This can lead to unstable connection between the positioning screws and the threaded holes, potentially causing slight wobbling within the threaded holes. This results in unstable cutter installation and severely affects the die's lifespan.
[0003] When the threaded hole deforms, the traditional approach is to replace the base, which requires disassembling the entire punching die from the die set, removing the base plate, replacing the base plate, and then reinstalling it. This method is time-consuming, labor-intensive, inefficient, costly, and affects production. Therefore, a punching die tool positioning structure is proposed to address the above problems. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a punching die tool positioning structure.
[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The punching die tool positioning structure of this utility model includes a mounting base plate and a punching die tool body; a mounting block is engaged inside the mounting base plate, a threaded ramp is provided on the inner side of the mounting block, a positioning screw is threadedly connected to the inner side of the threaded ramp, the punching die tool body is fixedly connected to the mounting block by the positioning screw, a base plate mounting hole is opened on the inner wall of the mounting base plate, an outer ring stud is threadedly connected to the inner wall of the base plate mounting hole, an inner ring threaded hole is opened on the inner wall of the outer ring stud, and an inner ring stud is threadedly connected to the inner ring threaded hole.
[0006] Preferably, the bottom of the mounting block is provided with an inner ring screw hole, and the upper end of the inner ring stud is connected and fixed to the mounting block through the inner ring screw hole.
[0007] Preferably, the lower surface of the punching die tool body is in close contact with the upper surface of the mounting base plate, and a positioning post is fixedly connected to the lower end of the punching die tool body.
[0008] Preferably, the inner end of the punching die cutter body is provided with a positioning groove, the positioning post is slidably installed on the inner side of the positioning groove, and a buffer rubber layer is fixedly connected to the outer wall of the positioning post, the buffer rubber layer being located inside the positioning groove.
[0009] Preferably, the mounting block and the positioning screw are provided in two sets, and the positioning screw is threadedly connected to the inside of the punching die cutter body.
[0010] The beneficial effects of this utility model are: 1. This utility model provides a positioning structure for punching die tools. Through the setting of a mounting block, positioning screws and threaded ramps, the threaded hole is opened in the mounting block. When the positioning screw is tightened downwards, the setting of the threaded ramps makes the positioning screw more and more secure, realizing the stable installation of the mounting block. When the threaded hole is deformed, only the mounting block needs to be replaced, without the need to remove the mounting base plate, which greatly improves efficiency and reduces costs by eliminating the need to replace the mounting base plate.
[0011] 2. This utility model provides a positioning structure for punching die tools. With the setting of an outer ring stud and an inner ring screw hole, the outer ring stud is installed inside the mounting base plate without disassembly. When disassembling and replacing the mounting block, it is only necessary to screw the inner ring stud into the inner ring screw hole to make the inner ring stud lose its reinforcement of the mounting block, and the mounting block can be pulled out. This facilitates the reinforcement of the mounting block without disassembling parts, making the operation convenient.
[0012] 3. This utility model provides a positioning structure for punching die cutters. By aligning the positioning post with the positioning groove, positioning post and buffer rubber layer, the installation position of the mounting base plate and the punching die cutter body can be quickly positioned, which facilitates the subsequent fastening installation work. The buffer rubber layer can buffer and offset the pressure during the use of the equipment. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0017] Specific implementation examples are given below.
[0018] Please see Figures 1-4 This utility model provides a positioning structure for a punching die tool, including a mounting base plate 1 and a punching die tool body 2; a mounting block 3 is fitted inside the mounting base plate 1, and a threaded ramp 8 is provided on the inner side of the mounting block 3. A positioning screw 7 is threadedly connected to the inner side of the threaded ramp 8. The punching die tool body 2 is fixedly connected to the mounting block 3 by the positioning screw 7. A base plate mounting hole 9 is opened on the inner wall of the mounting base plate 1, and an outer ring stud 10 is threadedly connected inside the base plate mounting hole 9. An inner ring screw hole 11 is opened on the inner wall of the outer ring stud 10, and an inner ring stud 12 is threadedly connected inside the inner ring screw hole 11.
[0019] Furthermore, such as Figure 1 and Figure 4 As shown, the bottom of the mounting block 3 is provided with an inner ring screw hole 11. The upper end of the inner ring stud 12 is connected and fixed to the mounting block 3 through the inner ring screw hole 11. There are two sets of mounting blocks 3 and positioning screws 7. The positioning screws 7 are threadedly connected to the inside of the punching die cutter body 2. The original threaded connection position of the positioning screws 7 and the mounting base plate 1 is changed to the mounting block 3. That is, a square groove is opened at the original threaded connection position of the mounting base plate 1, and the mounting block 3 is embedded in the square groove. The positioning screws 7 are threadedly connected to the mounting block 3 to position the punching die.
[0020] Furthermore, such as Figure 2 , Figure 3 and Figure 4As shown, the lower surface of the punching die cutter body 2 is tightly fitted with the upper surface of the mounting base plate 1. A positioning post 5 is fixedly connected to the lower end of the punching die cutter body 2. A positioning groove 4 is opened at the inner end of the punching die cutter body 2. The positioning post 5 is slidably installed on the inner side of the positioning groove 4. A buffer rubber layer 6 is fixedly connected to the outer wall of the positioning post 5. The buffer rubber layer 6 is located inside the positioning groove 4. The positions of the positioning post 5 and the positioning groove 4 correspond to each other. After aligning the two, the mounting base plate 1 and the mounting block 3 are also quickly aligned. It can be quickly positioned, which is fast, efficient and highly accurate.
[0021] Working principle: Align the mounting block 3 with the square hole on the die-cutting tool body 2, insert the mounting block 3 into the die-cutting tool body 2, and then use a tool to screw the inner ring stud 12 inside the outer ring stud 10 upwards. The inner ring stud 12 rotates upwards into the mounting block 3, thus reinforcing the mounting block 3. Align the positioning pin 5 installed at the lower part of the die-cutting tool body 2 with the positioning groove 4 opened on the mounting base plate 1, and then insert the positioning pin 5 into the positioning groove 4. This achieves quick positioning of the mounting base plate 1 and the die-cutting tool body 2. Then, remove the positioning screw 7 and align the positioning screw 7 with the die-cutting tool body 2. The threaded holes of the body 2 and the mounting block 3 are used for connection. The positioning screw 7 is screwed into the interior of the punching die cutter body 2 and the mounting block 3 using a tool. When the lower end of the positioning screw 7 is rotated to the position of the threaded ramp 8, since the threaded ramp 8 is narrow at the bottom, the more the positioning screw 7 rotates downward, the more it pushes the mounting block 3 outward, making the mounting block 3 more securely close to the punching die cutter body 2, thus achieving a stable installation. When removing the mounting block 3, the positioning screw 7 is unscrewed upward, and the inner ring stud 12 is screwed downward into the inner ring threaded hole 11 opened inside the outer ring stud 10, so that the mounting block 3 can be pulled out for replacement.
[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
