Description

Technical Field

[0001] The utility model relates to the technical field of rivet pressing, in particular to a combined rivet pressing device. Background Art

[0002] The combined rivet pressing device is a device used for riveting operations. It is mainly composed of a rivet pressing head part, a pressure applying system and a workbench part. When it is working, after the rivet is placed and positioned, the pressure applying system drives the rivet pressing head to rivet the rivet, causing the rivet to deform to firmly connect the workpiece. This device has the advantages of multi-function, high precision and improved efficiency, and can meet the riveting needs of various types of rivets and workpieces.

[0003] However, in the prior art, the rivet pressing head part of the combined rivet pressing device is mostly of a single specification and shape. When facing different types of rivets, such as round, flat, and special-shaped rivets, a rivet pressing head of a single shape cannot be effectively adapted, which may cause uneven deformation of the rivets during the riveting process, affecting the riveting quality and greatly reducing the firmness of the connection. At the same time, for rivets of different sizes, a rivet pressing head of a single specification may not be able to fully cover or accurately act on the rivets, and insufficient riveting or excessive riveting may easily occur. The former will cause the connection to become loose, and the latter may damage the rivet or the workpiece. Furthermore, in diversified production scenarios, such as the riveting of different automotive parts or multiple electronic product casings, the rivet pressing head of a single specification and shape greatly limits the scope of application of the device, and requires frequent replacement of equipment or the use of other auxiliary means to complete the riveting, which reduces production efficiency and increases production costs.
