Description

Technical Field

[0001] The utility model relates to the technical field of hinge processing equipment, in particular to a hinge stamping and curling forming device. Background Art

[0002] A hinge, also known as a hinge, is a mechanical device used to connect two solid objects and allow them to rotate relative to each other. Hinges are made of movable components or foldable materials. They are primarily installed on doors, windows, and cabinets. Hinges may be powder-coated, zinc alloy-plated, galvanized steel, sandblasted, chrome-plated zinc alloy, nickel-plated steel, brushed, or polished. They are categorized by material into stainless steel, iron, and hydraulic hinges.

[0003] At present, when hinges are stamped and curled, two stamping mechanisms are often required. One of the stamping mechanisms first stamps the hinge sheet once or twice to give it a certain curvature, and then the sheet needs to be moved to another stamping mechanism, which is used to curl the stamped curvature on the sheet. During the stamping and curling process of the hinge, workers need to constantly move the stamped hinge sheet, which is inconvenient. Although some stamping devices use a driving source to drive several stamping dies to perform different stamping processes of multiple sheets to enable continuous forming, although the operation is simplified, workers still need to constantly adjust the position of the stamped sheet during the stamping process and move its position to the bottom of the corresponding stamping mechanism, so that the workers' labor workload is still high, which greatly affects the efficiency of hinge stamping and curling.

[0004] Therefore, it is necessary to provide a hinge stamping and curling forming device to solve the above technical problems. Utility Model Content

It not only reduces the workload of workers, but also improves the efficiency of hinge stamping and curling.

[0032] A limiting groove 12 is provided on the front of the support plate 3, and a limiting plate 13 is slidably connected to the inside of the limiting groove 12. The limiting plate 13 is fixedly connected to the stamping plate 5. An avoidance groove 14 is provided on the top of the workbench 1, and U-shaped plates 15 are fixedly connected on both sides of the workbench 1.

[0033] The driving assembly includes a motor 16 and two conveyor rollers 17. The motor 16 is fixedly mounted on the front side of one of the U-shaped plates 15. The two conveyor rollers 17 are rotatably connected between the front and back sides of the inner walls of the two U-shaped plates 15. A conveyor belt 18 is transmission-connected between the outer surfaces of the two conveyor rollers 17. The bottoms of the two telescopic rods 7 are fixedly connected to the conveyor belt 18. The output end of the motor 16 is fixedly connected to one end of one of the conveyor rollers 17.

[0034] The clamping assembly includes two telescopic rods 19 fixedly connected to the top of the placement plate 9. The placement plate 9 is L-shaped. The outer surface of the telescopic rod 19 is provided with a spring 20. The top of the two telescopic rods 19 is fixedly connected to a clamping plate 21.

[0035] Working principle: During operation, by manually pulling the clamping plate 21, the corresponding rubber plate 22 is driven to move upward, and the telescopic end of the corresponding telescopic rod 2 19 is extended. After the spring 20 is stretched, the hinge sheet to be stamped and curled can be placed on the placement plate 9. After the pulled clamping plate 21 is released, it is clamped and fixed by the reset rubber plate 22. Then, the motor 16 is started by the controller 11, so that its output end drives one of the conveying rollers 17 to rotate.

It is sent to another stamping die base 2 on one side so that the raised end is punched again to produce an arc. At the same time, the other sheet metal on the side of the sheet metal close to the motor 16 is repeated so that one end is initially punched and raised to produce an arc. Then the sheet metal that has been punched twice can be transported to the last stamping die base 2. Under the support of the corresponding fixed plate 10 on the placement plate 9 and the cooperation with the corresponding stamping die 6, the sheet metal that has been punched twice to produce an arc can be punched and curled at the raised part to complete the stamping work of the sheet metal.
