초록 ▼

A method and apparatus for riveting two workpieces (20, 22) together by simultaneously upsetting both ends of a slug rivet (12). The present apparatus includes a frame portion (44) which may deflect during the rivet upsetting operation and a frame compensation booster assembly (164) which is provided to ensure that movement of the upper riveting ram relative to the frame portion (44) is increased an amount equal to the frame deflection so that the workpieces will be maintained in a substantially fixed work plane during the upsetting operation. Before the slug rivet is upset and after the slug rivet has been snugly engaged by the riveting rams (50, 60) the pressure behind the riveting rams is equalized by introducing fluid into the cylinder (48) until the pressure within the cylinder (48) equals the pressure within the cylinder (56). This is to prevent movement of the workpiece at the commencement of the upsetting operation.

대표청구항 ▼

A method for riveting two or more side-by-side workpieces together with opposed upper and lower riveting ram assemblies, the workpieces being provided with aligned apertures in which a slug rivet has been inserted; comprising the following steps: positioning the upper riveting ram assembly against an upward movement limiting stop to establish an upper die cavity; applying an upward force to move the lower riveting ram assembly upwardly towards the upper riveting ram assembly until both ends of the slug rivet are snugly engaged between adjacent ends of the upper and the lower riveting ram assemblies; applying a downward force to the upper riveting ram assembly after both ends of the slug rivet are snugly engaged until the after both ends of the slug rivet are snugly engaged until the downward force of the upper riveting ram assembly equals the upward force applied to the lower riveting ram assembly, without any deformation of the rivet occuring due to the equal forces; and then; simultaneously moving the upper and lower ram assemblies towards each other to simultaneously form upset heads on both ends of the rivet, thereby compensating for deflection of a frame carrying said upper and lower ram assemblies.
