Abstract
Description
Technical Field
[0001] This utility model relates to the field of stamping die technology, specifically a dual-station switching stamping die. Background Technology
[0002] In the field of metal stamping, traditional single-station stamping dies have long faced the technical challenge of balancing production efficiency and operational safety. Existing stamping equipment generally adopts a single-cavity structure. After one stamping cycle is completed, the equipment must be stopped, and the operator must manually open the die, remove the formed workpiece, and place the blank to be processed.
[0003] During this process, workers' hands need to frequently enter the mold working area. Even if the equipment is equipped with safety light curtains or emergency stop buttons, under high-intensity repetitive work, operators may still be injured by the closing mold due to fatigue, negligence, or equipment malfunction. Moreover, after each processing is completed, the workers need to remove the workpiece from the lower mold before the material can be loaded again, making it inconvenient to carry out continuous processing production in actual processing.
[0004] Based on this, a dual-station switching stamping die is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0026] In one embodiment, such as Figures 1-6As shown, a dual-station switching stamping die includes a lower die 11 and an upper die 16. A connecting sleeve 12 is fixedly provided on one side of the lower die 11. Two connecting sleeves 12 are respectively installed at both ends of a mounting plate 13. A rotating shaft is fixedly provided at the bottom end of the mounting plate 13. The rotating shaft is rotatably mounted in a mounting hole at the upper end of an operating table 15. The upper die 16 is fixedly mounted on the output end of a hydraulic cylinder 17. The hydraulic cylinder 17 is fixedly mounted in a mounting hole at the upper end of a support frame. The support frame is fixedly mounted at the upper end of the operating table 15. The upper die 16 is positioned above a lower die 11. The lower die 11 has a positioning mechanism inside for positioning the workpiece. The operating table 15 has an automatic unloading mechanism at its upper end. The positioning mechanism facilitates the positioning and fixing of the workpiece, while the unloading mechanism facilitates the automatic removal of the processed workpiece.
[0027] A fixed plate is fixedly mounted on the rotating shaft. Several reinforcing rods are provided between the upper end of the fixed plate and the bottom end of the mounting plate 13. One end of the rotating shaft is fixedly connected to the output end of the motor 14. The motor 14 is fixedly mounted on the bottom end of the operating table 15. The motor 14 is electrically connected to the control component. The control component is fixedly mounted on one side of the support frame. In use, when it is necessary to switch between the two lower molds 11, the output end of the motor 14 is controlled by the control component to drive the mounting plate 13 to rotate 180 degrees, thereby enabling the switching between the two lower molds 11.
[0028] The positioning mechanism includes a positioning frame 20. The lower mold 11 has storage slots around its perimeter, and each storage slot contains a positioning frame 20. A sliding rod 21 is fixedly mounted on each positioning frame 20. One end of each sliding rod 21 has a ball bearing, and a mounting plate is fixedly mounted on each sliding rod 21. One side of each mounting plate is fixedly connected to one end of a second return spring 22, and the other end of each second return spring 22 is fixedly connected to the lower mold 11. A guide frame 23 is fitted to one end of each sliding rod 21. Several guide frames 23 are fixedly mounted at the end of the upper mold 16. During use, when punching the workpiece... During pressing, the worker places the workpiece inside a lower mold 11. Then, the motor 14 drives the mounting plate 13 to rotate, causing the working positions of the two lower molds 11 to switch, so that the workpiece rotates to the lower part of the upper mold 16. Then, the control component controls the hydraulic cylinder 17 to start. The output end of the hydraulic cylinder 17 drives the upper mold 16 and the guide frame 23 to move. One end of the guide frame 23 is first in close contact with one end of the sliding rod 21. The end of the guide frame 23 guides the sliding rod 21. The sliding rod 21 pushes the positioning frame 20 to slide, so that the four positioning frames 20 clamp and position the workpiece around its perimeter. Then, the upper mold 16 punches the workpiece.
[0029] A support tube 24 is provided at the upper end of the operating table 15 corresponding to the position below the upper mold 16. Several support columns 25 are fixedly provided at the upper end of the support tube 24. A collection box 26 is provided at the bottom end of the operating table 15 corresponding to the position of the support tube 24. In use, after the lower mold 11 is rotated to the position below the upper mold 16, the bottom end of the lower mold 11 is in close contact with one end of the support column 25. When the upper mold 16 stamps the workpiece, the support column 25 can support the lower mold 11, thereby preventing the mounting plate 13 from bending. At the same time, the waste material after stamping by the upper mold 16 falls into the collection box 26.
[0030] A sliding plate 18 is slidably provided on the upper mold 16. A first return spring 19 is provided between the upper end of the sliding plate 18 and the end of the upper mold 16. In use, when the upper mold 16 finishes stamping and rises, the sliding plate 18 returns to the initial position under the action of the first return spring 19, thereby preventing the workpiece from moving with the upper mold 16.
[0031] The feeding mechanism includes a pusher plate 27. The lower mold 11 has symmetrically arranged limiting grooves, and each pusher plate 27 slides within one of these grooves. A tension spring 29 is fixedly attached to the bottom end of each pusher plate 27, with the other end of the tension spring 29 fixedly connected to the end of a fixed groove inside the lower mold 11. A pusher frame 28 is fixedly attached between the two sides of each pusher plate 27, and the pusher frame 28 slides within a mounting groove inside the lower mold 11. Two guide plates 30 are provided on the upper end of the operating table 15, each guide plate 30 positioned at a corresponding position on one end of each pusher plate 27. A bearing plate 31 is fixedly attached between the two guide plates 30. A limiting frame 32 is provided above the bearing plate 31 and is fixedly attached to one side of a fixed plate. Fixed on the upper end of the operating table 15, the bottom end of the limiting frame 32 is in close contact with the upper end of the lower mold 11. In use, after the workpiece is processed, the mounting plate 13 switches the lower mold 11. During the switching process, one end of the push plate 27 is in close contact with the guide plate 30. Since one end of the guide plate 30 is inclined, the guide plate 30 guides the push plate 27. The push plate 27 drives the push frame 28 to slide. The push plate 27 and the push frame 28 push the workpiece to rise. When one end of the push plate 27 is in close contact with the upper end of the guide plate 30, the upper ends of the push plate 27 and the push frame 28 are on the same plane as the upper end of the lower mold 11. As the mounting plate 13 continues to rotate, the limiting frame 32 intercepts the workpiece, so that the workpiece falls onto the upper end of the bearing plate 31, thereby completing the automatic unloading.
[0032] Each side of the lower mold 11 is symmetrically provided with a reinforcing frame 34, and a limiting block is inserted into one end of each reinforcing frame 34. The limiting block is fixedly installed at the end of the mounting plate 13, which facilitates the increase of the stability of the lower mold 11 during use.
[0033] Both ends of the mounting plate 13 are fixedly provided with auxiliary support legs 33, and one end of each auxiliary support leg 33 is provided with a ball bearing. The ball bearing is rolled on the upper end of the operating table 15, so as to facilitate auxiliary support for both ends of the mounting plate 13 during use.
[0034] The above embodiment discloses a dual-station switching stamping die. When a workpiece needs to be stamped, the operator places the workpiece inside a lower die 11. Then, the motor 14 drives the mounting plate 13 to rotate, switching the working positions of the two lower dies 11. This causes the workpiece to rotate to a position below the upper die 16. Subsequently, the control unit controls the hydraulic cylinder 17 to start. The output end of the hydraulic cylinder 17 drives the upper die 16 and the guide frame 23 to move. One end of the guide frame 23 is initially in close contact with one end of the sliding rod 21, and the end of the guide frame 23 guides the sliding rod 21. The sliding rod 21 pushes the positioning frame 20 to slide, so that the four positioning frames 20 clamp and position the workpiece from all sides. Then, the upper die 16 stamps the workpiece. The support column 25 can support the lower mold 11. After the workpiece is processed, the mounting plate 13 switches the lower mold 11. During the switching process, one end of the push plate 27 is in close contact with the guide plate 30. Since one end of the guide plate 30 is inclined, the guide plate 30 guides the push plate 27. The push plate 27 drives the push frame 28 to slide. The push plate 27 and the push frame 28 push the workpiece to rise. When one end of the push plate 27 is in close contact with the upper end of the guide plate 30, the upper ends of the push plate 27 and the push frame 28 are on the same plane as the upper end of the lower mold 11. As the mounting plate 13 continues to rotate, the limit frame 32 intercepts the workpiece, so that the workpiece falls onto the upper end of the bearing plate 31, thereby completing the automatic unloading.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
