Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, specifically to a positioning device for a bending machine used in metal product processing. Background Technology

[0002] Nowadays, with the development of technology and the continuous improvement of people's living standards, the use of metal products has also increased. The metal products industry includes the manufacturing of structural metal products, metal tools, containers and metal packaging containers, and stainless steel and similar daily-use metal products. With social progress and technological development, metal products are increasingly widely used in industry, agriculture, and all aspects of people's lives, creating greater and greater value for society. Steel sheet is one type of metal product. When processing products using metal sheet, bending is sometimes required, and this bending process requires specialized bending equipment.

[0003] A search revealed that Chinese Patent Publication (Announcement) No. CN216937815U discloses a positioning device for a bending machine used in metal product processing. The device is broadly described as including a bending machine body, on which are fitted upper and lower molds. The lower mold has fitted slides 1 and 2 on both sides, and stops 1 and 2 at the ends of slides 1 and 2. In use, clamping plates 1 and 2, along with a hydraulic cylinder, can clamp and position one end of the workpiece. Clamping blocks 1 and 2, and bolts... In combination, the other end of the workpiece can be clamped and positioned. The hydraulic cylinder one and the slider one, and the hydraulic cylinder two and the slider two work together to push the workpiece towards the center during processing, preventing the workpiece from shifting. However, the above device still has some shortcomings. For example, the distance between the two clamping plates one and the distance between the two clamping blocks two are not easy to adjust. Therefore, the above device is not suitable for clamping steel plates of different widths, and its practicality and applicability are somewhat lacking. To this end, we propose a positioning device for a bending machine for metal product processing. Utility Model Content

The bidirectional screw 4 drives the two sliders 3 to move closer together, and the sliders 3 move the fixed seats 5, fixed frame 6, etc., to facilitate clamping the steel plate between the two fixed seats 5. Then, start motor 10, which drives the bidirectional screw... When the screw 12 rotates, the two sliders 11 move closer together. The sliders 11 clamp the steel plate, making it suitable for clamping steel plates of different specifications. Then, the hydraulic cylinder 7 is activated, which lowers the lifting frame 8 and the pressure roller 9 to press the steel plate. Then, the hydraulic cylinder 15 moves, which lowers the upper mold 17 to cooperate with the lower mold 14 to bend the steel plate. At this time, the motor 2 can be activated to move the two fixed seats 5 closer together to cooperate with the bent steel plate. The pressure roller 9 will also rotate to cooperate with the bent steel plate, which facilitates better bending of the steel plate and improves the bending effect.
