Abstract
471,719. Stamping; punching. DECKEL, F., (trading as DECKEL PRAZISIONSMECHANIK UND MASCHINENBAU, F.). Feb. 2, 1937, No. 3099. Convention date, Feb. 3, 1936. [Class 83 (iv)] Relates to punching or stamping machines of the type shown in Fig. 1, with pillar guides 5, punch 2, stripper 4, die plate 8, and ejector 11 through which fine punches 10 pass, and consists in a construction in which the ejector plate 20, Fig. 2, which transmits pressure to the ejector 18, is rigidly but detachably connected thereto, and guided accurately by a long bearing surface 21 in the die plate 22. The ejector is provided with an eccentric projection 27 engaging the ejector plate 20, through which a thick positioning pin 26 also passes. In a modification the bearing surface of the ejector plate is made still more elongated, and in another modification a sleeve is interposed in the bearing. Lubricating grooves 23 are provided.
