Description

Technical Field

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

[0002] Metalworking, or metal processing for short, refers to the production activities of humans processing materials composed primarily of metallic elements or those with metallic properties. It is a technological process that transforms metal materials into items, parts, and components, encompassing large parts for bridges and ships, as well as small components for engines, jewelry, and watches. It is widely used in various fields such as science, industry, art, and handicrafts. Bending devices, also known as bending machines, come in many varieties. Different types of bending machines are needed for different materials and bending requirements. For example, sheet metal bending machines are used to bend thin sheets, while pipe bending machines are used to bend round pipes.

[0003] As disclosed in CN219724206U, a bending device for processing metal products includes a base; a central shaft is fixedly connected to the upper end of the base, a turntable is rotatably connected to the upper end of the base, a vertical plate is fixedly connected to the upper end of a connecting block, a threaded rod is threadedly connected to the right side of the vertical plate, and a baffle is fixedly connected to the right side of the threaded rod. The beneficial effects of this invention are as follows: the turntable has multiple sets of positioning holes at its upper end, and a pressing shaft is slidably connected to the upper end of each positioning hole. The distance between the pressing shaft and the central shaft can be changed by inserting it into different positioning holes, facilitating the bending of metals of different specifications.

[0004] While the aforementioned patent facilitates bending metals of different specifications, each adjustment can only be made in multiples of the diameter of the positioning hole. For example, if the spacing needs to be increased, it can be adjusted from the first positioning hole to the second positioning hole. This means that the spacing of each adjustment is limited by the inner diameter of the positioning hole, thus the adjustment method of the aforementioned device has significant limitations.
