Abstract
Description
Technical Field
[0001] This application relates to the field of steel processing technology, and more specifically, to a high-strength steel stamping die device with adjustable clearance. Background Technology
[0002] High-strength steel stamping dies are key tools for stamping high-strength steel. They mainly consist of an upper die and a lower die. The upper die is mounted on the slide of the stamping equipment, and the lower die is placed on the worktable. During the stamping operation, the upper die moves downward with the slide to press the high-strength steel material, causing the material to undergo plastic deformation within the specific space of the upper and lower dies, thereby obtaining stamped parts of the required shape and size. Typically, the die material is selected from alloy steels with high hardness, high strength, and good wear resistance to withstand the enormous pressure and friction during the stamping process and ensure a long service life. At the same time, the structural design of the die must ensure the stability, precision, and reliability of the stamping process, thereby meeting the high-quality requirements of high-strength steel stamped parts.
[0003] Existing high-strength steel stamping dies generate gaps during stamping. If the gap is too large, the high-strength steel material is prone to wrinkling during stamping, resulting in uneven surfaces and uneven deformation of the stamped parts, reducing dimensional and shape accuracy. If the gap is too small, the material is subjected to excessive extrusion pressure, which can easily cause cracks or even fractures, seriously affecting the strength and reliability of the stamped parts. Inappropriate gaps can also exacerbate die wear, increase friction between the die and the material, and intensify frictional heat generation when the gap is small, leading to problems such as adhesive wear and abrasive wear, shortening die life, and requiring frequent die replacements, which increases costs and affects production schedules, thereby increasing cost expenditures and reducing production efficiency.

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0027] Reference Figures 1-5 An adjustable gap high-strength steel stamping die device includes an upper die base 1 and a lower die base 2. The bottom of the upper die base 1 is provided with a stamping seat 3, the bottom of the stamping seat 3 is provided with a stamping head 4, the top of the lower die base 2 is provided with a die cavity 9, and the outer side of the stamping head 4 is provided with a filling component.
[0028] The filling assembly includes an adjustment unit and an installation unit. The adjustment unit includes a filling block 5. The outer wall of the mold cavity 9 is provided with multiple fixing strips 10. The structure of the filling block 5 is adapted to the structure of the fixing strips 10. The filling block 5 is used to fill the gap between the stamping head 4 and the mold cavity 9.
[0029] Reference Figures 1-5 A mounting base 6 is provided on one side of the stamping head 4. The top of the filling block 5 is slidably connected to the inner wall of the mounting base 6. A telescopic rod 7 is provided between the filling block 5 and the mounting base 6. A spring 8 is sleeved on the outer wall of the telescopic rod 7. One side of the filling block 5 is inclined. One side of the multiple fixing strips 10 is also inclined. A cylinder 17 is provided between the upper die base 1 and the lower die base 2. The number of cylinders 17 is set to multiple.
[0030] The gap between the punch head 4 and the mold cavity 9 can be adjusted by filling the component. Specifically, during the punching process, if significant deformation of the material in the length direction is observed, requiring adjustment of the gap in that direction, the filling component is first installed in the direction where the gap needs adjustment. Then, cylinder 17 is activated. Multiple cylinders 17 provide relatively stable power. The function of cylinder 17 is to move the upper mold base 1, thereby changing the relative position between the punch head 4 and the mold cavity 9. Since a mounting base 6 is provided on one side of the punch head 4, the top of the filling block 5 is connected to the mounting base 6. The inner wall of the seat 6 is slidably connected, and a telescopic rod 7 and a spring 8 are provided between the filling block 5 and the mounting seat 6. When the cylinder 17 drives the upper mold seat 1 to move, it will drive the punch head 4 and the mounting seat 6 to move together. The movement of the mounting seat 6 will cause the filling block 5 to be squeezed by the fixing strip 10 on the outer wall of the mold cavity 9. During this process, the filling block 5 will gradually move towards the gap between the punch head 4 and the mold cavity 9 under the squeezing of the fixing strip 10, so that the filling block 5 can fill the gap between the punch head 4 and the mold cavity 9, thereby realizing the adjustment of the gap between the punch head 4 and the mold cavity 9.
[0031] The filling component can dynamically adjust the gap between the stamping head 4 and the mold cavity 9 according to the actual situation, ensuring that the appropriate gap size is maintained in different stamping stages, thereby improving the dimensional and shape accuracy of the stamped parts. The gap can be adjusted in real time to avoid the accumulation of errors and ensure the stable quality of each stamped part. Moreover, the filling component can ensure that the gap is always kept within a reasonable range, reducing wear and scratches on the mold surface. No machine downtime is required, which greatly improves production efficiency and extends the service life of the mold.
[0032] Reference Figures 1-5The mounting unit includes multiple mounting slots 11, which are respectively opened around the stamping head 4. Each mounting slot 11 has a connecting slot 12 at its bottom, and the mounting slot 11 and the connecting slot 12 are connected. A connecting block 14 is fixedly connected to one side of the mounting base 6, and a locking block 13 is fixedly connected to one side of the connecting block 14. The structure of the mounting slot 11 is adapted to the structure of the locking block 13, and the structure of the connecting block 14 is adapted to the structure of the connecting slot 12. A blocking block 16 is inserted into one side of each mounting slot 11 and the connecting slot 12. Multiple bolts 15 are provided at the bottom of the stamping head 4, and each locking block 13 is connected to the corresponding locking block 13 by two corresponding bolts 15.
[0033] The installation unit allows for the installation of a filler block 5 on a designated side of the stamping head 4 as needed. The specific operation involves first determining the side of the stamping head 4 where the filler block 5 needs to be installed, based on the material deformation during stamping and the requirements for gap adjustment. Then, the connecting block 14 of the mounting base 6 is aligned with the mounting groove 11 of the stamping head 4. The locking block 13 on one side of the connecting block 14 is aligned with the mounting groove 11. Since the structure of the mounting groove 11 is compatible with the structure of the locking block 13, and the structure of the connecting block 14 is compatible with the structure of the connecting groove 12, the connecting block 14 is first inserted into the connecting groove 12, then moved downwards to allow it to slide along the connecting groove 12. Finally, the locking block 13 is fixed from the bottom using two bolts 15, thus achieving the installation of the filler block 5.
[0034] The installation unit allows for adjustments based on specific material deformation and clearance requirements. A filling block 5 is installed on a designated side of the stamping head 4, enabling flexible handling of various deformation conditions and improving the mold's adaptability. Different installation positions can be selected according to actual needs. This flexibility allows the mold to adapt to different stamping tasks, enhancing its versatility. Furthermore, it is simple and quick to operate, saving manpower and material costs.
[0035] By setting a shielding block 16 inside the mounting slot 11 when not in use, debris can be prevented from entering the mounting slot 11, keeping the mounting area clean, facilitating subsequent installation operations, and extending the service life of the mounting unit.
[0036] Working principle: During the stamping process, if the material is found to have large deformation in the length direction and it is necessary to adjust the gap in the length direction, firstly, a filling component is installed in the direction where the gap needs to be adjusted, and then cylinder 17 is activated. The setting of multiple cylinders 17 can provide relatively stable power. The function of cylinder 17 is to drive the upper die base 1 to move, thereby changing the relative position between the stamping head 4 and the die cavity 9. Since there is a mounting seat 6 on one side of the stamping head 4, the top of the filling block 5 is slidably connected to the inner wall of the mounting seat 6, and there is a telescopic rod 7 and a spring 8 between the filling block 5 and the mounting seat 6. When the cylinder 17 drives the upper die base 1 to move, it will drive the stamping head 4 and the mounting seat 6 to move together. The movement of the mounting seat 6 will cause the filling block 5 to be squeezed by the fixing strip 10 on the outer wall of the die cavity 9. In this process, the filling block 5 will gradually move towards the gap between the stamping head 4 and the die cavity 9 under the squeezing of the fixing strip 10, so that the filling block 5 can fill the gap between the stamping head 4 and the die cavity 9, thereby realizing the adjustment of the gap between the stamping head 4 and the die cavity 9.
[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
