ABSTRACT:
An apparatus and method for assembling articles such as clips, comprising first and second components formed from metallic sheet stock, said apparatus including an outer annular member and second and third dial members mounted within the annular member, the annular and dial members being rotatably mounted in a synchronized manner associated with the cycling of a die press. A pair of article components are punched from a sheet of metallic stock during each press cycle and are pushed through an opening in a die block to be received and held at a receiving station in a horizontal orientation in respective ones of a plurality of clamping assemblies formed in each of the outer annular member and second inner dial member, respectively. A pair of article components are punched on a continuous basis with each press cycle with the successively formed pairs of components being received in successive pairs of clamping assemblies which rotatably index under the die block opening.
As the annular and second dial member rotatably index, the respective clamping assemblies pivot until the first and second article components are held in a vertical orientation.
Apparatus is provided at a transfer station for transferring each second article component held in a second dial member clamping assembly to one of a plurality of clamping assemblies provided in the third inner dial member thereby reversing the article component with respect to its outwardly facing surface.
Successive pairs of first and second article components now held in the clamping assemblies of the outer annular member and third inner dial member respectively are indexed into confronting relationship at an assembly station wherein means are provided for assembling the article. The assembled article is then ejected from the apparatus subsequent to various finishing operations, such as burr removal.
