Description

Technical Field

[0001] The utility model relates to the field of processing equipment, in particular to a bending and riveting integrated machine. Background Technique

[0002] Riveting, namely rivet connection, is a mechanical term, which is a method of connecting multiple parts by using axial force to upset the nail rod in the rivet hole of the part and form a nail head.

[0003] Bending means that under the pressure of the upper die or lower die of a bending machine, a metal sheet first undergoes elastic deformation and then enters plastic deformation. In the initial stage of plastic bending, the sheet is freely bent. As the upper die or lower die presses on the sheet, the sheet gradually fits closely with the inner surface of the V-shaped groove of the lower die. At the same time, the radius of curvature and the bending force arm also gradually become smaller. Continue to apply pressure until the stroke ends, so that the upper and lower dies and the sheet are in full contact at three points. At this time, a V-shaped bend is completed, which is commonly known as bending.

[0004] When performing bending and riveting processing on a product, it is necessary to perform separate bending and riveting operations on the product. This step is rather cumbersome. After a product completes one processing, it is also necessary to collect it and then transfer its position, which will waste a lot of processing time and affect the overall efficiency.

[0005] Therefore, it is very necessary to propose a bending and riveting integrated machine to solve the above problems. Content of the Utility Model

[0006] The main purpose of the utility model is to provide a bending and riveting integrated machine, which can effectively solve the problems in the background technique.

[0007] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0008] The bending and riveting integrated machine includes a frame, and a double-stroke cylinder, an upper die assembly, a product rough limit assembly and a lower die assembly are installed in the inner cavity of the frame.

Limit pins are symmetrically installed on the sides of the two blanking cylinders. Bending cylinders are symmetrically installed on both sides of the top of the upper die assembly. Bending heads are symmetrically installed at the bottoms of the two bending cylinders.

On both sides of the back of the top of the lower die assembly, riveting cylinders are symmetrically installed. On the front of the two riveting cylinders, riveting heads are symmetrically installed.
