Description

Technical Field

[0001] This utility model relates to the field of stamping technology for parts processing, specifically a stamping device for preventing misalignment in parts processing. Background Technology

[0002] Stamping is a process for processing metal sheets, strips, or profiles using a punch and dies. A punch applies pressure to the material placed in the lower die, causing it to deform or separate, thus achieving operations such as punching, blanking, bending, and deep drawing. Stamping offers advantages such as high production efficiency, high processing precision, high material utilization, and the ability to process complex shapes. It is widely used in industries such as automotive, electronics, home appliances, and machinery. In the stamping process, the design and manufacture of the dies are crucial, directly affecting the shape, size, and quality of the parts.

[0003] During the stamping process, if the stamping device lacks effective measures to fix and correct the parts, the parts are prone to misalignment due to external forces. Once misalignment occurs during the stamping process, the dimensional and shape accuracy of the stamped parts cannot meet the design requirements, resulting in scrapped parts or the need for secondary processing, which increases production costs and processing time. Misaligned parts can also impact or squeeze the stamping die, causing die damage, shortening the die's service life, and increasing the cost of die maintenance and replacement. Due to the need for frequent inspection and adjustment of part positions, as well as the handling of scrap caused by misalignment, stamping production efficiency is greatly reduced.

[0004] Therefore, this utility model provides an anti-misalignment stamping device for parts processing to solve the above problems. Utility Model Content

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0031] This utility model provides a stamping device for preventing misalignment during parts processing, such as... Figures 1-6 As shown, the technical solution includes a workbench 1, a cylinder 4 is fixedly installed on the top of the inner cavity of the workbench 1, an upper abutment plate 5 is fixedly connected to the output shaft of the cylinder 4, an upper mold 6 is fixedly connected to one side of the upper abutment plate 5 by several bolts, a number of guide sleeves 9 are fixedly connected to the bottom of the upper mold 6, a guide post 10 is slidably connected to the inner cavity of the guide sleeve 9, a lower mold 7 is provided below the upper mold 6, a punch 12 is fixedly connected to the top of the upper mold 6, a discharge port 31 is opened on the top of the lower mold 7, a structural groove 11 is opened on the top of the lower mold 7, and a base plate 8 is provided below the lower mold 7.

[0032] The top of the base plate 8 is provided with a placement groove 20, the inner cavity of the placement groove 20 is provided with a bidirectional lead screw 21, the outer ring of the bidirectional lead screw 21 is provided with two threaded sleeves 23, the top of the threaded sleeves 23 is fixedly connected to the housing 22 by a connecting block, and a clamping plate 25 is fixedly connected to one side of the housing 22. The bottom of the upper mold 6 is provided with two embedding grooves 13.

[0033] The bottom of the guide post 10 is fixedly connected to the top of the lower die 7, and one side of the base plate 8 is fixedly connected to one side of the adjacent lower die 7 by several bolts. The bottom of the base plate 8 is fixedly connected to the bottom of the inner cavity of the worktable 1. The guide post 10 can guide the precise movement of the upper die 6, ensuring the accuracy and stability of the stamping process. At the same time, the firm connection between the base plate 8 and the worktable 1 enhances the load-bearing capacity and structural strength of the entire device, and can effectively withstand the large pressure generated during the stamping process, thereby improving the service life and reliability of the device.

[0034] One end of the bidirectional lead screw 21 is rotatably connected to the inner wall of the adjacent placement slot 20 via a rotating shaft, and the other end of the bidirectional lead screw 21 extends through the inner wall of the adjacent placement slot 20 to one side of the base plate 8. Driven by the motor 19, the bidirectional lead screw 21 can rotate smoothly and drive the screw sleeve 23 to move, ensuring the stable rotation and precise transmission of the bidirectional lead screw 21, thereby accurately controlling the two housings 22 to move closer or further apart, and thus achieving a stable clamping of the parts.

[0035] A motor 19 is fixedly installed on one side of the base plate 8. The output end of the motor 19 is fixedly connected to the extension end of the bidirectional lead screw 21. The precise control of the motor 19 can realize the rotation of the bidirectional lead screw 21.

[0036] A slider 24 is fixedly connected to the bottom of the outer surface of the threaded sleeve 23. A groove is provided at the bottom of the inner cavity of the placement groove 20. The bottom end of the slider 24 is slidably connected to the inner cavity of the groove. When the bidirectional lead screw 21 rotates to drive the threaded sleeve 23 to move, the slider 24 slides smoothly in the groove. This sliding connection method can effectively prevent the threaded sleeve 23 from deflecting or shaking during the movement, thereby ensuring the smooth movement of the housing 22 and the stable clamping of the parts by the clamping plate 25.

[0037] A through hole 26 is provided at the bottom of the inner cavity of the housing 22. A movable rod 29 is provided in the inner cavity of the housing 22. The bottom end of the movable rod 29 is inserted into the inner cavity of the through hole 26. Through the insertion structure between the through hole 26 at the bottom of the inner cavity of the housing 22 and the bottom end of the movable rod 29, the movable rod 29 can move up and down in the through hole 26. This structure allows the movable rod 29 to flexibly adjust its position, thereby driving the abutment block 32 to firmly fix parts of different thicknesses within a certain range, enhancing the stability of the parts during the stamping process, and further improving the stamping quality and production efficiency.

[0038] A spring 30 is fitted around the outer ring of the moving rod 29, and a baffle 33 is fitted around the outer ring of the moving rod 29. One end of the spring 30 is fixedly connected to the top of the inner cavity of the adjacent housing 22, and the other end of the spring 30 is fixedly connected to one side of the corresponding baffle 33. When the moving rod 29 moves up and down under the action of external force, the spring 30 can generate elastic deformation and provide restoring force. This elastic connection method allows the abutment 32 to automatically adjust the pressure according to the thickness of the part, so as to better adapt to the fixing requirements of parts of different thicknesses within a certain range.

[0039] The top of the moving rod 29 is fixedly connected to a block 27 through the top of the corresponding inner cavity of the housing 22. Anti-slip pads 28 are fixedly connected to both sides of the block 27, and a stop block 32 is fixedly connected to one side of the block 27. The operator can easily move the block 27 up and down by holding the anti-slip pads 28, thereby moving the moving rod 29 and the stop block 32. The anti-slip pads 28 improve the comfort and safety of operation, while the stop block 32 can firmly fix the upper part of the part.

[0040] A through groove 16 is provided on one side of the lower mold 7. A collection frame 14 is slidably connected to the inner cavity of the through groove 16. A handle 15 is fixedly connected to one side of the collection frame 14. Two positioning rods 18 are fixedly connected to one side of the collection frame 14. Two positioning holes 17 are provided on the inner wall of one side of the discharge port 31. The outer surface of the positioning rod 18 is inserted into the inner cavity of the corresponding positioning hole 17. The insertion structure of the positioning rod 18 and the positioning hole 17 ensures the stable placement and accurate positioning of the collection frame 14. The handle 15 makes it convenient for the operator to remove the collection frame 14 from the through groove 16, realizing the unified treatment of waste materials, improving the efficiency and convenience of waste material collection, maintaining the cleanliness of the working environment, and reducing the safety hazards caused by waste material accumulation.

[0041] Two reinforcing plates 2 are fixedly connected to both sides of the workbench 1, and two support legs 3 are fixedly connected to the bottom of the reinforcing plates 2. The reinforcing plates 2 can enhance the structural strength and stability of the workbench 1, while the support legs 3 provide a solid support for the entire device. This structural arrangement makes the stamping device more stable and reliable during operation.

[0042] Specifically: When stamping is required, the operator first places the part to be stamped on the upper part of the lower die 7, then starts the motor 19. The motor 19 drives the bidirectional lead screw 21 to rotate, and the slider 24 slides in the inner cavity of the slide groove. This causes the bidirectional lead screw 21 to drive the two threaded sleeves 23 to move closer to each other along their surfaces. The movement of the threaded sleeves 23 further pushes the housing 22 inward, thereby driving the clamping plate 25 to move inward synchronously, ultimately achieving stable clamping of both sides of the part. After the clamping plate 25 completes the clamping action, the operator holds the block 27 set at the top of the moving rod 29 and applies an upward pulling force. At this time, the anti-slip pad 28 can effectively improve the grip stability. As the block 27 moves upward, the moving rod 29 slides upward inside the through hole 26, and the spring 30 is compressed and stores energy. The abutment 3 connected to the top of the moving rod 29... 2. The spring 30 then rises above the part. When the block 27 is released, the spring 30 releases its elastic potential energy to push the moving rod 29 downward to reset, so that the abutment 32 is pressed tightly against the upper surface of the part, thereby achieving adaptive fixing of parts of different thicknesses within a certain range. After the part is positioned and clamped, the cylinder 4 starts and pushes the upper abutment 5 downward. The upper abutment 5 drives the upper mold 6 and the punch 12 set below it to move downward synchronously. At the same time, the guide post 10 slides smoothly along the inside of the guide sleeve 9 to ensure vertical accuracy and running stability during the stamping process. The punch 12 finally performs precise stamping operation on the part. The waste generated during the stamping process falls into the collection frame 14 through the discharge port 31. When it is necessary to clean up the waste, the operator can pull the collection frame 14 out of the through slot 16 through the handle 15 for centralized waste disposal and to keep the working environment clean.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
