Description

Technical Field

[0001] This utility model relates to the field of punching die technology, and in particular to a punching and blanking die for a connecting plate. Background Technology

[0002] Connecting plates are key connecting components widely used in fields such as machinery manufacturing, construction engineering, and automotive industry. They are usually metal sheets that have been processed and formed to achieve rigid connections between equipment parts, steel structural components, or pipelines. Their structural accuracy directly affects the overall assembly stability and operational safety. These plates need to be processed with bolt holes, positioning holes, and other installation structures through a punching process, and their shape contours that meet the design dimensions are obtained through a blanking process.

[0003] Current blanking and punching dies cannot be used continuously. After each punching operation, the processed workpiece must be manually removed and a new workpiece placed for the next operation. This increases labor intensity, reduces production efficiency, and poses certain safety hazards to operators. Therefore, this application proposes a blanking and punching die for connecting plates. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a punching and blanking die for connecting plates.

[0020] 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.

[0021] This utility model provides a technical solution: such as Figure 1-4 As shown, a punching and blanking die for a connecting plate includes a base plate 1. Multiple feet 2 are symmetrically mounted on the bottom surface of the base plate 1. A top plate 3 is fixedly mounted on the top surface of the base plate 1. A first hydraulic cylinder 4 is mounted on the top surface of the top plate 3. A bearing plate 5 is mounted at the bottom end of the first hydraulic cylinder 4. A punching assembly is mounted on the bottom surface of the bearing plate 5. A lower die base 10 is fixedly mounted on the top surface of the base plate 1. A collecting assembly is mounted on the bottom surface of the base plate 1 and is connected to the lower die base 10. Conveyor seats 13 are fixedly mounted on both sides of the top surface of the base plate 1. A positioning assembly is mounted on the outer side of each conveyor seat 13. Multiple first electric push rods 17 are symmetrically installed on the top wall of the seat 13. The bottom ends of the multiple first electric push rods 17 located on the same side are all equipped with a first U-shaped frame 18. A pressure roller 19 is rotatably connected between the two inner sides of each first U-shaped frame 18. A conveying roller 21 is rotatably connected between the two inner sides of each first electric push rod 17. A drive motor 20 is fixedly installed on the outer side of each conveying seat 13. The output shaft of each drive motor 20 is coaxially connected with the corresponding conveying roller 21. A plate 6 is placed on the top of the base plate 1. The plate 6 is placed on the top surface of the two conveying rollers 21.

[0022] The friction between the plate 6 and the conveying roller 21 is increased by pressing the plate 6 with the first electric push rod 17, so that the conveying roller 21 can be driven to rotate intermittently by the drive motor 20, and the plate 6 can be automatically conveyed.

[0023] Furthermore, each positioning component includes two second U-shaped frames 25, and the two second U-shaped frames 25 are symmetrically slidably connected to the outside of the corresponding conveyor seat 13. Each side of the second U-shaped frame 25 is rotatably connected to a plurality of side rollers 26. Each side of the conveyor seat 13 is symmetrically installed with two side plates 23. Each side plate 23 is fixedly installed with a second electric push rod 24 on its outside, and the other end of each second electric push rod 24 is fixedly connected to the outside of the corresponding second U-shaped frame 25.

[0024] The two outer sides of the plate 6 can be positioned by the second electric push rod 24, the side plate 23 and the side roller 26 to ensure that the plate 6 will not shift.

[0025] Furthermore, the stamping assembly includes multiple second hydraulic cylinders 7, which are symmetrically mounted on the bottom surface of the first hydraulic cylinder 4. The bottom ends of the multiple first hydraulic cylinders 4 are jointly equipped with a punch head 8 and a cutting blade 9. Punching is achieved through the punch head 8, and the cutting blade 9 cuts the formed part of the sheet metal 6.

[0026] Furthermore, the collecting component includes a punching hole 14 and a blanking groove 15, and the punching hole 14 and the blanking groove 15 are opened on the top surface of the lower die base 10. The shapes of the punching hole 14 and the blanking groove 15 are respectively adapted to the shapes of the punching head 8 and the cutting blade 9. A collecting seat 11 is fixedly installed on the bottom surface of the base plate 1. A drawer box 12 is slidably connected inside the collecting seat 11, and the drawer box 12 is connected to the lower die base 10.

[0027] Waste materials and formed plates can be collected in drawer 12 through the punching hole 14 and the blanking groove 15.

[0028] Furthermore, the collection assembly also includes two partition plates 16, which are respectively installed in the lower mold base 10 and the drawer box 12. The stamping hole 14 and the blanking groove 15 are respectively arranged on both sides of the partition plate 16. The waste material and the formed plate can be separated by the partition plate 16, which facilitates subsequent processing.

[0029] Furthermore, each conveyor seat 13 has two symmetrically formed grooves 22 on its outer side, and each second U-shaped frame 25 is slidably connected to the corresponding groove 22.

[0030] This utility model provides a connecting plate punching and blanking die. The specific working principle is as follows: First, the plate 6 is placed on the top surface of the two conveying rollers 21. Then, the second electric push rod 24 in the positioning assembly is activated. The second electric push rod 24 pushes the second U-shaped frame 25 to slide in the slide groove 22 on the outside of the conveying seat 13, so that the side rollers 26 contact the two outer sides of the plate 6 to position the plate 6 and ensure that it will not shift.

[0031] Then, the first electric push rod 17 is activated, which drives the first U-shaped frame 18 and the pressure roller 19 to move downward until the pressure roller 19 squeezes the plate 6, increasing the friction between the plate 6 and the conveying roller 21.

[0032] Afterwards, the drive motor 20 intermittently drives the conveyor roller 21 to rotate, and under the action of friction, it drives the plate 6 to move, realizing the automatic conveying of the plate 6. When the plate 6 is conveyed to the processing position above the lower mold base 10, the drive motor 20 stops working.

[0033] At this time, the first hydraulic cylinder 4 drives the bearing plate 5 to move downward, while the second hydraulic cylinder 7 drives the punch head 8 and the cutting blade 9 to move downward; the punch head 8 punches the plate 6, and the generated waste material falls into one side of the drawer box 12 through the punching hole 14. The cutting blade 9 cuts off the formed part of the plate 6, and the formed plate falls into the other side of the drawer box 12 through the material drop groove 15. The partition plate 16 separates the waste material and the formed plate.

[0034] After processing is completed, the first hydraulic cylinder 4 and the second hydraulic cylinder 7 drive the stamping assembly to reset upwards, and the drive motor 20 works again to continue to transport the processed sheet metal 6 forward. At the same time, the unstamped part of the sheet metal 6 is continued to be transported to the processing position to start the next round of processing.

[0035] 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.
