Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, in particular to a bending device for processing household appliance accessories. Background Art

[0002] With the continuous development of society, the continuous popularization of household appliances, and the increasing demand for household appliances, the intelligent production of household appliances is constantly promoted to speed up production efficiency and meet supply needs. In the process of household appliances production and processing, pipes with different curvatures often appear. Pipes with different curvatures can be adapted to different positions of household appliances, and then in the production process, a bending machine is required to bend the pipes into a fixed shape. The bending device generally clamps the pipes through the central axis of the working disk and the surrounding iron shafts. When working, the pipes are squared between the central axis of the working disk and the corresponding forming axis, on the inner side of the iron shaft, according to the bending shape of the pipes. When the working disk rotates, one end of the pipe is prevented from rotating by the iron shaft, the position of the central axis remains unchanged, and the forming axis rotates in an arc around the central axis to bend the pipes. In the bending process, since the pipe fittings are not fixed, the position will shift under the strong bending force of the bending machine when the bending device is bending, thereby reducing the bending accuracy of the pipe fittings, thereby affecting the quality of the pipe bending. At the same time, general pipe fittings need to be bent after arrangement, and the pipe bending machine is not convenient to move, and it is impossible to bend the pipe fittings at different angles. Therefore, the pipe fittings need to be constantly adjusted to complete the bending of the pipe fittings at different angles, which reduces the efficiency of pipe bending. For this reason, we propose a bending device for processing household appliance accessories. Utility Model Content
