Abstract

PURPOSE: To eliminate a necessity of a secondary process for removing a flush of a barrel and the like by a method wherein a surface of a cutting edge is formed so that a flush produced upon a press cutting may not be protruded out of a thickness of a work to be cut.
CONSTITUTION: Molds for a press producing a flush is constituted with a top force 9, a bottom tool 10, an effective cutting surface 11 which is a left side face of the bottom tool 10 and a protuberance 12 protruded upwardly and flush with the surface 11. An upper surface 14 of the protuberance 12 is a part of the cutting edge provided so that a flush 8 of a work 6 to be cut, which is a material for a contact metal, may not be protruded out of a thickness l of the material while a damage of the protuberance 12 may be prevented. A slope 15 lowered toward right end thereof and a contoured portion 16 are a part of a portion for forming a sloped portion 17. In case a material for contact is cut by using the press molds of this constitution in order to use the product as a contact piece, a secondary process for removing a flush is not necessitated, therefore, an economical and high-qualitied contact point may be obtained.
