Abstract
563,105. Making articles from strip. CARR FASTENER CO., Ltd., PARKIN, L., and SIMPSON, J. April 19, 1943, No. 6242. [Classes 83 (ii) and 83 (iv)] Articles, such as contact pins for thermionic valves &c. are made from strip fed step-bystep through a die to form a tube and in the intervals between feeding upset to form a collar at or near one end, the article being cut off at a predetermined distance from the collars. Strip a is fed through an opening 5 in a plunger 3 to a rough forming die 4 and finish forming die 4a. Gripping-dies 19, 20 mounted in a frame 17 close by the action of a resiliently mounted cam pin 21 mounted in a punch head 28 to hold the strips with the required length of tube projecting. A die 26 domes the upper end of the tube and upsets it to form a collar and the plunger 3 then descends forming a fresh length of tube. Cams 16 on the plunger 3 engage adjustable abutments 14 in levers 10 and close cutters 7, sliding in grooves in the frame 1 underneath the frame 17, on the tube cutting off the finished article. The head 28 then ascends and the gripping dies release the tube which is fed upwards by the plunger 3, ejecting the cut-off article.
