Description

Technical Field

[0001] This utility model relates to the field of punching device technology, specifically a sheet metal bending and punching device. Background Technology

[0002] Sheet metal parts are products manufactured using radius processing techniques and are widely used in daily life. They are characterized by their light weight, high strength, electrical conductivity, and low cost, which influences many manufacturers to carry out large-scale production. They are widely used in the electrical and communication industries. There are many processes involved in processing sheet metal parts, one of which is bending. After bending, the sheet metal parts need to be punched.

[0003] Currently, sheet metal processing requires bending and punching to be done separately, which cannot be done simultaneously, reducing the efficiency of bending and punching. Furthermore, after punching, the sheet metal parts need to be disassembled, which is very time-consuming and will reduce the efficiency of sheet metal punching operations. Therefore, we propose a sheet metal bending and punching device. Utility Model Content

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] Example: Figures 1-6 As shown, this utility model discloses a sheet metal bending and punching device, including an operating table 1, a workbench 2 fixedly connected to the top of the operating table 1, a fixed platform 3 fixedly connected to the surface of the workbench 2, mounting blocks 4 fixedly connected to both sides of the lower end of the workbench 2, a lead screw 5 and a lead screw 6 rotatably connected between the two mounting blocks 4, slide rails 7 are provided on both sides of the surface of the workbench 2, a movable frame 8 is slidably connected inside the slide rails 7, and the lower end of the movable frame 8 is threadedly connected to the lead screw 5, a movable frame 9 is slidably connected inside the other end of the slide rails 7, and the lower end of the movable frame 9 is threadedly connected to the outer circumference of the lead screw 6, a through groove 10 is provided at the lower end of the movable frame 8, and the through groove 10 is slidably connected to the lead screw 6, and a through groove 21 is provided at the lower end of the movable frame 9, and the through groove 21 is slidably connected to the lead screw 5.

[0026] The movable frame 8 has a sliding connection to a lifting block 12, and a telescopic rod 13 is fixedly connected to the upper end of the lifting block 12. The upper end of the telescopic rod 13 is fixedly connected to the top of the movable frame 8, and a bending blade 14 is fixedly installed at the bottom of the lifting block 12.

[0027] The lifting block 12 is fixedly mounted with a bidirectional motor 15 on one side. The two ends of the bidirectional motor 15 are connected to rotating columns 16. One end of each rotating column 16 is fixedly connected to a spur gear 17. The moving frame 8 is fixedly connected with a rack 18, which meshes with the spur gear 17. By setting the rotating columns 16 and cooperating with the spur gear 17 and rack 18, the height of the lifting block 12 can be adjusted, which can be used to bend sheet metal parts of different thicknesses, greatly improving the bending efficiency of sheet metal parts.

[0028] The movable frame 9 has two hydraulic rods 19 fixedly installed at its upper internal fixed position. The output ends of the hydraulic rods 19 are fixedly connected to the slide plate 20, and the two ends of the slide plate 20 are slidably connected to the movable frame 9. A punching machine 21 is fixedly embedded inside the slide plate 20. By setting the punching machine 21, the bent sheet metal parts can be punched without the need for manual punching operations. This not only reduces the workload of workers, but also improves the punching efficiency of sheet metal parts.

[0029] The fixed platform 3 has a bidirectional threaded rod 22 rotatably connected inside its surface. The two ends of the bidirectional threaded rod 22 are threaded with two moving blocks 23. The top of the moving blocks 23 is fixedly connected with a clamping block 24. By setting the moving blocks 23, the sheet metal parts that need to be drilled or bent can be fixed and limited to prevent the sheet metal parts from shifting during bending or drilling, thereby improving the quality of processing.

[0030] The upper end of the fixed platform 3 is fixedly connected to a slider 25, and the surface of the slider 25 is slidably connected to a lower mold 26. A dust suction port 27 is fixedly installed on one side of the fixed platform 3. By setting the lower mold 26, the lower mold 26 can be replaced according to the bending requirements, thereby expanding the bending range and meeting people's needs.

[0031] The operating table 1 is equipped with a vacuum cleaner 28, and the output end of the vacuum cleaner 28 is fixedly connected to a filter chamber 29. The filter chamber 29 is equipped with a filter screen 30, and one side of the filter chamber 29 is connected to the suction port 27 through a conveying pipe 31. By setting up the filter chamber 29, debris or dust will be generated during the drilling process. The vacuum cleaner 28 will clean the debris and dust on the surface of the fixed table 3, improving the environmental cleanliness during the drilling process. In addition, the filter chamber 29 can also be used to collect and store debris and dust for centralized treatment.

[0032] Working principle: In use, the sheet metal part is placed between two clamping blocks 24. By rotating the bidirectional threaded rod 22, the moving blocks 23 at both ends move relative to each other, so that the clamping blocks 24 clamp and fix the two ends of the sheet metal part. The lower mold 26 is slidably installed, and then the screw 15 is rotated to move the moving frame 8, so that the bending blade 14 moves above the lower mold 26. By starting the bidirectional motor 15, the output end of the bidirectional motor 15 drives the spur gear 17 to rotate, which meshes with the rack 18, so that the lifting block 12 moves down, so that the bending blade 14 bends the sheet metal part. After bending is completed, the screw 15 is rotated again to move the moving frame 8 to the top of the lower mold 26. Frame 8 is moved back to its initial position, then mold 26 is slid off and removed. Screw 26 is rotated to move the moving frame 9 directly above the sheet metal part. Hydraulic rod 19 is activated, causing the output end of hydraulic rod 19 to drive slide plate 20 downward. Drilling machine 21 is activated to drill holes in the sheet metal part. At the same time, vacuum cleaner 28 is activated. During the drilling process, debris or dust will be generated. The debris or dust on the surface of fixed table 3 is absorbed and cleaned through vacuum port 27 and transported to filter chamber 29 through conveying pipe 31, improving the environmental cleanliness during the drilling process. In addition, filter chamber 29 also facilitates the collection and storage of debris and dust for centralized treatment.
