Detailed Implementation

[0016] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0017] Reference Figure 1-5 This utility model provides a vertical cutting and trimming device for a punching die, which includes a workbench 2. A support frame 1 is fixedly connected to the upper end of the workbench 2. An electric telescopic column 6 is fixedly connected to the lower end of the support frame 1. An upper die 5 is arranged below the electric telescopic column 6. A cutter 11 is fixedly connected to one side of the upper die 5. Multiple telescopic rods 14 are fixedly connected to the lower end of the upper die 5. A sleeve 16 is movably fitted at the lower end of each telescopic rod 14. A No. 1 spring 15 is movably fitted on the outside of each sleeve 16. A pressure plate 9 is fixedly connected to the lower end of each sleeve 16.

[0018] Specifically, the workbench 2 serves as the basic support platform for the device. The support frame 1 suspends the electric telescopic column 6 above the workbench 2, aligning it with the processing area below. The electric telescopic column 6 drives the upper mold 5 to move by extending and retracting up and down, providing vertical power for punching and trimming. The lower end of the upper mold 5 is equipped with a cutter 11 and a pressing structure, which move up and down with the electric telescopic column 6. The cutter 11 is fixed to one side of the upper mold 5 and cuts off the waste material at the edge of the material when the upper mold 5 moves down. The telescopic rod 14 slides in the sleeve 16 to ensure that the pressure plate 9 does not shift when it moves up and down. The first spring 15 is compressed and generates a reaction force, allowing the pressure plate 9 to press the material tightly. The pressure plate 9 contacts the material and presses it before the cutter 11 trims it, preventing the material from shifting during the punching process.

[0019] A lower mold 4 is provided below the upper mold 5, and a limit block 7 is fixedly connected to the outside of the lower mold 4.

[0020] Specifically, the lower mold 4 corresponds to the upper mold 5. The material is placed on its upper end, and when the upper mold 5 presses down, it cooperates with the lower mold 4 to complete the punching.

[0021] The upper mold 5 is fixedly connected to a fixed seat 10. Multiple bolts 13 are threadedly connected to one side of the fixed seat 10. The lower end of the electric telescopic column 6 is provided with a threaded groove 12. One end of the bolt 13 is threadedly connected to the inside of the threaded groove 12.

[0022] Specifically, the fixed seat 10 provides a connection interface for the electric telescopic column 6. The bolt 13 passes through the fixed seat 10 and is screwed into the threaded groove 12 of the electric telescopic column 6 to lock and fix the upper mold 5 to the electric telescopic column 6. The threaded groove 12 and the bolt 13 cooperate to form a threaded connection. The upper mold 5 can be disassembled or installed by loosening or tightening the bolt 13.

[0023] A limit rod 17 is fixedly connected to the upper end of the pressure plate 9, and the limit rod 17 is internally slidably connected to the upper mold 5.

[0024] Specifically, the limiting rod 17 is fixed to the upper end of the pressure plate 9 and slidably connected inside the upper mold 5, forcing the pressure plate 9 to move only in the vertical direction of the limiting rod 17, preventing deviation or tilting.

[0025] A fixed plate 22 is fixedly connected to the upper end of the workbench 2. A placement groove 18 is opened inside the fixed plate 22. A pull rod 3 is movably fitted inside the placement groove 18. A pin 19 is fixedly connected to one end of the pull rod 3. A second spring 21 is provided between the pin 19 and the placement groove 18. A limit groove 8 is opened on one side of the fixed plate 22.

[0026] Specifically, the fixing plate 22 provides installation space for components such as the pull rod 3 and the pin 19. The placement groove 18 serves as a movement channel for the pull rod 3 and the pin 19, limiting their range of movement. The pull rod 3 is manually pulled to control the extension and retraction of the pin 19, facilitating the insertion or removal of the lower mold 4. The pin 19 is inserted into the lower mold 4 to fix it in a designated position. The second spring 21 is sleeved on the outside of the pin 19. When the pull rod 3 is pulled, the second spring 21 is compressed. After the pull rod 3 is released, the second spring 21 rebounds, causing the pin 19 to automatically reset and lock. The limiting groove 8 is opened on one side of the fixing plate 22 to restrict the movement of the lower mold 4.

[0027] The lower mold 4 has a fitting hole 20 at its lower end, and a pin 19 is fitted inside the fitting hole 20.

[0028] Specifically, the shape of the fitting hole 20 matches that of the pin 19. After the pin 19 is inserted into the fitting hole 20, it can fix the lower mold 4 on the worktable 2.

[0029] The limiting block 7 has a cutting groove inside, and the cutter 11 is fitted into the cutting groove of the limiting block 7.

[0030] Specifically, the shape and position of the groove and the cutter 11 correspond. When the cutter 11 moves down with the upper mold 5, it will be embedded in the groove, which can completely cut off the waste material and prevent the cutter 11 from directly hitting the limit block 7.

[0031] Working principle: The material to be processed is placed on the upper end of the lower mold 4. The electric telescopic column 6 is activated, and the electric telescopic column 6 extends and retracts downward. Through the fixed seat 10 and bolts 13, it drives the upper mold 5 to move downward. When the upper mold 5 moves downward, the pressure plate 9, which is movably fitted inside the sleeve 16 via the telescopic rod 14, first contacts the material. As the upper mold 5 continues to move downward, the first spring 15 outside the sleeve 16 is compressed, generating a reaction force that makes the pressure plate 9 press tightly against the material. The limiting rod 17 at the upper end of the pressure plate 9 slides inside the upper mold 5 to prevent the pressure plate 9 from shifting and avoid material displacement. Subsequently, the cutter 11 on one side of the upper mold 5 moves downward. When the cutter 11 is embedded in the groove of the limiting block 7, the waste material at the edge is completely cut off. The groove also prevents the cutter 11 from hitting the limiting block 7. After punching is completed, the electric telescopic column 6 retracts upward. The upper mold 5 is reset, and the pressure plate 9 is released from the material under the action of the first spring 15. The workpiece can be removed to complete one work process. When changing the mold, the upper mold 5 can be replaced by loosening the bolt 13 on one side of the fixed seat 10, so that the bolt 13 is released from the threaded groove 12 at the lower end of the electric telescopic column 6, and the old upper mold 5 can be directly removed and replaced with the new upper mold 5. When changing the lower mold 4, pull the pull rod 3. The pull rod 3 drives the pin 19 to slide in the placement groove 18 of the fixed plate 22 and compress the second spring 21, placing the lower mold 4 on the worktable 2, so that the fitting hole 20 at the lower end of the lower mold 4 is aligned with the pin 19. After releasing the pull rod 3, the second spring 21 rebounds and pushes the pin 19 into the fitting hole 20. At the same time, the lower mold 4 cooperates with the limiting groove 8 of the fixed plate 22 to achieve the positioning and fixation of the lower mold 4.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
