Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, and in particular to a stamping device. Background Technology

[0002] Large stamping equipment typically has multiple consecutive stamping stations, and each stamping station is equipped with stamping dies for the corresponding process. However, the stamping dies of existing large stamping equipment are generally directly mounted on the base. The position adjustment of the stamping die is generally for horizontal adjustment, with little consideration for vertical height adjustment. When a certain height difference is formed between the stamping die of a certain stamping station and the adjacent stamping die, it may affect the forming accuracy of the stamped workpiece, resulting in problems such as stamping position deviation and workpiece dimensional deviation.

[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a stamping device that adjusts the longitudinal height of the stamping die according to actual usage requirements to ensure that the working surface height of the stamping die at each station remains consistent.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A stamping device includes a base bed, on which a plurality of stamping bodies are distributed along its length. A worktable is provided on the stamping body, and a lower die mounting base is provided on the worktable. A plurality of through holes are provided on the lower die mounting base, and a plurality of positioning posts are provided on the worktable corresponding to each of the through holes. The positioning posts are engaged with the through holes. A gasket assembly is provided at the bottom of the lower die mounting base at the position of the positioning posts, and the gasket assembly is detachably connected to the positioning posts.

[0007] In the stamping device, the shim assembly includes multiple height adjustment shims stacked sequentially from bottom to top. The height adjustment shims are detachably connected to the positioning post, and the topmost height adjustment shim abuts against the bottom of the lower die mounting base.

[0008] In the aforementioned stamping device, the height adjustment shim is provided with a slot that opens to one side, and the slot is adapted to the column body of the positioning post.

[0009] In the stamping device, one side of the height adjustment shim extends outward from the edge of the lower die mounting base.

[0010] In the stamping device, a pull-out hole is provided on the extended end of the height adjustment shim.

[0011] In the stamping device, the upper part of the positioning post is at least partially provided with external threads, and the upper part of the positioning post is threadedly connected with a clamping nut, the bottom of the clamping nut abutting against the top of the lower die mounting base.

[0012] In the aforementioned stamping device, at least one lower die mounting groove is provided on each of the top two sides of the lower die mounting base.

[0013] In the aforementioned stamping device, the stamping body includes a frame, a hydraulic assembly is provided on the top of the frame, an upper die mounting base is provided at the output end of the hydraulic assembly, and a worktable is provided on the frame, with the worktable located below the upper die mounting base.

[0014] In the aforementioned stamping device, the top and bottom surfaces of the height adjustment shim are each provided with multiple grooves.

[0015] Beneficial effects:

[0016] This utility model provides a stamping device. To ensure precise and efficient positioning of the lower die mounting base and the worktable, this solution adopts a quick positioning structure combining through holes and positioning pins. During installation, the through holes on the lower die mounting base are first precisely aligned with the positioning pins on the worktable to ensure accurate positioning of the lower die mounting base. Next, the height difference between the lower die mounting base and the worktable is finely adjusted using shim assemblies to achieve flatness of the working surfaces of each lower die mounting base. By replacing shim assemblies with different thicknesses, the working plane of each lower die mounting base can be precisely adjusted, avoiding differences in the processing quality of stamped workpieces due to differences in the height of the lower die.

Detailed Implementation

[0023] This utility model provides a stamping device. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0024] In the description of this utility model, it should be understood that the terms "middle," "inner side," "outer side," etc., indicate the orientation or positional relationship of this utility model based on the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

[0025] Please see Figures 1 to 5This utility model provides a stamping device, including a base bed 1, on which multiple stamping bodies 2 are distributed along their length. The stamping bodies 2 are adaptively configured according to the stamping process. Through the multiple stamping bodies 2, different blanking actions are performed on the stamping workpiece to continuously stamp out finished stamped workpieces. A worktable 21 is provided on each stamping body 2, and a lower die mounting base 3 is provided on the worktable 21. By providing the lower die mounting base 3 on the worktable 21, it is convenient for workers to install different stamping dies, reducing costs. The installation of the stamping die is complex. The lower die mounting base 3 has multiple through holes 31, and the worktable 21 has multiple positioning posts 4 corresponding to each through hole 31. The positioning posts 4 are connected to the through holes 31. A shim assembly 5 is located at the bottom of the lower die mounting base 3, at the position of the positioning posts 4. The shim assembly 5 is detachably connected to the positioning posts 4. To achieve efficient positioning between the lower die mounting base 3 and the worktable 21, this design employs a quick positioning structure that uses the through holes 31 to engage with the positioning posts 4. During installation, the through holes 31 on the lower die mounting base 3 must first be aligned with the positioning posts 4 on the worktable 21 to ensure correct installation of the lower die mounting base 3. Subsequently, the height between the lower die mounting base 3 and the worktable 21 is finely adjusted using the shim assembly 5 to ensure the flatness of the working surfaces of each lower die mounting base 3. By replacing the shim assembly 5 with shims of different thicknesses, the working planes of each lower die mounting base 3 can be precisely adjusted, thereby avoiding the impact of height differences between lower dies on the processing quality of the stamped workpiece. This design not only improves installation efficiency but also ensures the accuracy and consistency of workpiece processing.

[0026] In actual use, the stamping dies are pre-installed on the corresponding lower die mounting base 3. Then, the staff checks the working height of each stamping die. If it is found that the working height of any stamping die is different from the working height of other stamping dies, the working height of all stamping dies is leveled by replacing the shim assembly 5 of different thicknesses.

[0027] like Figures 1 to 5 As shown, the pad assembly 5 further includes multiple height adjustment pads 51 stacked sequentially from bottom to top; by stacking different numbers of height adjustment pads 51, the overall height of the pad assembly 5 can be adjusted, allowing the operator to more flexibly adjust the working height of the lower mold mounting base 3.

[0028] In one embodiment, all height adjustment shims 51 maintain a consistent height. By strictly standardizing the height of all height adjustment shims 51, it is ensured that the height of each shim conforms to a uniform standard, thereby achieving height standardization for the overall height of the shim assembly 5. This not only makes the installation and use of the shim assembly 5 more convenient but also effectively reduces the difficulty of adjusting the mold height during stamping, improving work efficiency and product quality.

[0029] Specifically, the height adjustment shim 51 is detachably connected to the positioning post 4, and the topmost height adjustment shim 51 abuts against the bottom of the lower mold mounting base 3; the height adjustment shim 51 can be detachably connected to the positioning post 4, making the installation of the height adjustment shim 51 more secure and relatively stable during operation, and when it needs to be replaced, it can be quickly removed from the positioning post 4.

[0030] like Figures 1 to 5 As shown, the height adjustment shim 51 is further provided with a slot 52 opening to one side, which is adapted to the column of the positioning post 4. By designing a slot 52 with an opening on the height adjustment shim 51, the height adjustment shim 51 can be easily inserted into the reserved gap between the lower mold mounting base 3 and the worktable 21 in a lateral insertion manner, and achieve a precise and stable engagement with the positioning post 4. In this way, when the operator needs to replace the height adjustment shim 51, it is not necessary to completely remove the entire lower mold mounting base 3 from the positioning post 4. The height adjustment shim 51 can be simply inserted or pulled out from the side of the gap to efficiently complete the replacement of the shim assembly 5. At the same time, this slot 52 design with an opening not only greatly simplifies the operation process, but also significantly enhances the connection between the height adjustment shim 51 and the positioning post 4, effectively avoiding the displacement of the height adjustment shim 51 during use, thereby ensuring the stability and safety of the entire device.

[0031] like Figures 1 to 5 As shown, furthermore, one side of the height adjustment shim 51 extends outward from the edge of the lower mold mounting base 3; by adding an extension to the height adjustment shim 51, the purpose is to facilitate convenient disassembly and replacement of the height adjustment shim 51 by the operator when needed. This extension ensures that it will not be interfered with or affected by the lower mold mounting base 3 during actual use, thereby ensuring the smoothness and efficiency of the entire disassembly and replacement process.

[0032] like Figures 1 to 5As shown, the height adjustment shim 51 is further provided with a pull-out hole 53 on its extended end; the design of the pull-out hole 53 not only takes into account the convenience of actual operation, but also conforms to the ergonomic design principle, so that the staff can operate more easily and naturally, and facilitate the staff to pull out the height adjustment shim 51.

[0033] like Figures 1 to 5 As shown, the upper part of the positioning post 4 is at least partially provided with external threads, and a clamping nut 6 is threadedly connected to the upper part of the positioning post 4. The bottom of the clamping nut 6 abuts against the top of the lower die mounting base 3. By configuring the clamping nut 6 at the top of the positioning post 4, the fixing stability of the lower die mounting base 3 can be significantly improved. Specifically, with the help of the clamping nut 6, the raised lower die mounting base 3 can be firmly locked and fixed in a predetermined position, effectively avoiding the unstable phenomenon of up-and-down vibration caused by external forces during the stamping process. This design not only enhances the overall stability of the equipment, but also significantly reduces the processing errors and production risks caused by vibration, ensuring the smooth progress of the stamping operation and the stable guarantee of product quality.

[0034] like Figures 1 to 5 As shown, further, at least one lower die mounting groove 32 is provided on each of the top two sides of the lower die mounting base 3; by providing the lower die mounting groove 32, the connection between the stamping lower die and the lower die mounting base 3 can be facilitated, and the stamping lower die can be quickly positioned by using the lower die mounting groove 32. The stamping lower die is provided with a connecting slot hole that cooperates with the lower die mounting groove 32, and then the connecting slot hole and the lower die mounting groove 32 are connected by a bolt assembly.

[0035] like Figures 1 to 5 As shown, the stamping body 2 further includes a frame 22, a hydraulic component 23 is provided on the top of the frame 22, an upper die mounting base 24 is provided at the output end of the hydraulic component 23, and a worktable 21 is provided on the frame 22 and is located below the upper die mounting base 24. During operation, the hydraulic component 23 uses its retractable output end to drive the upper die mounting base 24 to move the upper stamping die toward the lower stamping die on the lower die mounting base 3 to perform stamping processing, so as to complete the stamping processing of the stamped workpiece on the lower stamping die.

[0036] It should be noted that this stamping device is equipped with a traction device, specifically including a traction shaft and a traction motor, at its input or output end. This traction device effectively moves various sheet metal or plates. The traction device enables precise and stable movement of the base material of the stamped part, ensuring that the base material can smoothly pass through each stamping body 2 for stamping. In this process, the base material undergoes continuous and orderly stamping processing, ultimately forming a structurally complete and reliable stamped workpiece, thus meeting production requirements.

[0037] like Figures 1 to 5 As shown, the height adjustment shim 51 further has multiple grooves 54 distributed on both its top and bottom surfaces; to enhance the stability and reliability of the height adjustment shim 51, multiple groove structures 54 are provided on the surface of the height adjustment shim 51. The purpose is to significantly enhance the contact friction between the height adjustment shims 51 by increasing the surface roughness. In practical applications, this enhanced friction effectively prevents misalignment or displacement of the height adjustment shims 51 during use, ensuring the normal operation of the equipment and production efficiency.

[0038] Furthermore, the multi-groove structure 54 simultaneously increases the friction between the height adjustment shim 51, the lower mold mounting base 3, and the worktable 21. This increased friction greatly improves the stability of the height adjustment shim 51 installation, ensuring its stability under pressure and impact, and preventing loosening or detachment.

[0039] In summary, to ensure precise and efficient positioning between the lower die mounting base 3 and the worktable 21, this solution employs a quick-positioning structure combining through holes 31 and positioning pins 4. During the installation process, it is crucial to first ensure precise alignment between the through holes 31 on the lower die mounting base 3 and the positioning pins 4 on the worktable 21 to guarantee accurate positioning of the lower die mounting base 3. Next, the height difference between the lower die mounting base 3 and the worktable 21 is finely adjusted using shim assemblies 5 to achieve flatness of the working surfaces of each lower die mounting base 3. By replacing shim assemblies 5 with different thicknesses, precise control of the working planes of each lower die mounting base 3 can be achieved, effectively avoiding differences in stamping workpiece processing quality caused by height differences between the lower dies.
