Title: Casting for impact clutch hammer frame and its production
Inventor: JIYON EMU KURATSUPU
IPC: B22D25/02
Filed: 1993-04-02
Abstract: PURPOSE: To promote the directional solidification of a casting in a driven end and to improve physical propertie in the whole casting by forming a tapered shape in at least one direction for achieving the directional solidification toward a non-drawn shaft. CONSTITUTION: A casting for impact clutch hammer frame is provided with a means for facilitating the boring from the one end part to the other end part in the closed wall. Solid webs 103, 103' are provided with inner surfaces 106, 106' with only a slight flattened section. The tip part of a cone is directed toward the driven end, i.e., the masses of the webs 103, 103' are reduced toward the driven end. Structurally unnecessary thickness is removed from the cover parts and the ridge parts 107 in the casting. Since this improved casting 110 is formed as small cross section in the supporting part of the inside web, the metal quantity to be machined is small. This casting is obtd. by pouring molten metal into the vertically downward position via a sprue.
