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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-6 A replaceable stamping die for sheet metal punching and shearing includes a stamping machine 1. A base 2 is fixedly mounted in the middle of the stamping machine 1. A movable groove 15 is opened in the middle of the base 2. A sliding groove 3 and a sliding groove 9 are respectively opened on the outer wall of the base 2. A slide 8 is slidably connected to the top of the base 2. A limit block 13 is fixedly mounted at the bottom of the slide 8. A screw 4 is rotatably connected to the outer wall of the limit block 13. A screw 10 is fixedly mounted on the outer wall of the slide 8. A fastening nut 5 is threadedly connected to the outer walls of both screw 4 and screw 10. A screw 3 11 is fixedly mounted on the top of the slide 8. A fastening nut 12 is threadedly connected to the outer wall of screw 3 11. A pressure plate 7 is tightly fitted to the bottom of the fastening nut 12. A body 6 is tightly fitted to the bottom of the pressure plate 7. A clamping plate 14 is fixedly mounted on the outer wall of the slide 8. A round hole 16 is opened on the outer wall of the base 2.
[0023] In the above structure, the punch press 1, base 2, slide groove 1 3, screw 1 4, fastening nut 1 5, body 6, pressure plate 7, slide block 8, slide groove 2 9, and screw 2 10 allow the operator to adjust the state of slide block 8 and pressure plate 7 by rotating fastening nut 1 5 and fastening nut 2 12 during use. This allows for adjustment of the distance between the two slide blocks 8, and pressure plate 7 can also be detached from body 6, making it convenient for users to replace body 6 with different models and sizes, thereby improving the application range of the punch press.
[0024] In a preferred embodiment: the inner wall of the circular hole 16 is threadedly connected to the outer wall of the screw 4, and the slide 8 is fixedly connected to the base 2 by the fastening nut 5.
[0025] In the above structure, through the set circular hole 16 and screw 4, during operation, the user can unscrew the fastening nut 5 to make the fastening nut 5 disengage from the base 2, so that the screw 4 can rotate smoothly, thereby making it easy for the user to adjust the distance between the two slides 8, and thus ensuring that the use of the mold is not affected.
[0026] In a preferred embodiment, the outer wall of the clamping plate 14 is tightly fitted to the outer wall of the body 6, and the body 6 is fixedly connected to the base 2 by the pressure plate 7.
[0027] In the above structure, with the body 6 and pressure plate 7, after the user places the body 6, the pressure plate 7 can press the body 6 by tightening the fastening nut 12, thereby preventing the body 6 and the workpiece from shifting during the stamping process, thus ensuring the stability of the mold and the stamping accuracy of the workpiece during the stamping process.
[0028] In a preferred embodiment: the top of the inner wall of the movable groove 15 is slidably connected to the outer wall of the limiting block 13, and the outer wall of the limiting block 13 is also slidably connected to the inner wall of the sliding groove 9.
[0029] In the above structure, the limiting block 13 and the slide groove 9 are provided. The slide groove 9 can cooperate with the limiting block 13 to limit the slide 8, so that the slide 8 cannot be separated from the base 2 during the movement. Therefore, the user does not need to adjust the connection between the slide 8 and the base 2, thereby improving the user's operation and installation efficiency of the stamping die.
[0030] In a preferred embodiment: the outer wall of the screw 10 is slidably connected to the inner wall of the groove 3, and the bottom of the clamping plate 14 is slidably connected to the top of the base 2.
[0031] In the above structure, the clamping plate 14 is used to clamp the two sides of the body 6 after the pressure plate 7 is attached to the body 6, thereby assisting the pressure plate 7 in limiting the body 6 and further improving the stability of the stamping die during operation.
[0032] In a preferred embodiment, the number of limiting blocks 13 is three, and the three limiting blocks 13 are evenly distributed along the bottom of the slide block 8.
[0033] In the above structure, the three limiting blocks 13 are set to limit the sliding block 8 during the sliding process, preventing it from tilting or even shifting position, thus ensuring that the sliding block 8 moves horizontally and improving the stability of the sliding block 8 during the movement.
[0034] Working principle: First, during installation, the user can tighten the fastening nut 15 and fastening nut 22 to adjust the position of the slide block 8. Then, rotate the screw 14 to allow the slide block 8 to slide along the top of the base 2. With the cooperation of the limiting block 13 and the sliding groove 29, the slide block 8 is limited to prevent the slide block 8 from shifting position. This achieves the effect of clamping the body 6 of different sizes and models, thereby improving the application range of the stamping die and making it easier for the user to replace the stamping die. After replacement, the body 6 is clamped and limited by the pressure plate 7 and the clamping plate 14 respectively, preventing tilting or even positional shift. This ensures that the body 6 and the workpiece can be accurately aligned during the stamping process of the stamping machine 1, thereby improving the stability of the stamping die and the stamping accuracy of the workpiece.
