有する。Structure of the conventional example and its problems In the conventional process for manufacturing a malleable metal cylindrical case, as shown in FIGS. The billet 1 is placed in the stopper hole B, and then the extrusion punch 3 having the forming part A is used to push the billet 1 at a predetermined pressure in the direction of the arrow X. Next, the extrusion punch 3 moves in the Y direction, and the cylindrical case 4 moves to the stripper 5.
It will be removed from the extrusion punch 3. In this case, the cylindrical case 4 has a waving phenomenon at the case opening C, and the height of the case becomes non-uniform in the circumferential direction, and if this continues, it cannot be used as a product as a cylindrical case. For this purpose, edge cutting is performed in the post-process.

。However, the above configuration requires three steps: billet production, extrusion processing, and edge cutting processing, resulting in poor productivity.
In order to obtain the cylindrical case 7 in the edge cutting process, scrap 6 is generated and the material yield is also poor.

ストを低減して生産性を高めるという効果を有する。Structure of the Invention The present invention provides a punch having a tapered part for suppressing undulations that occur at the mouth of a cylindrical case after molding, and a punch that can receive the entire side of the case to stabilize the shape of the cylindrical case after extrusion. Consists of a die with a deep hole, a knockout for ejecting the product from the deep hole, and a stripper for removing the product from the punch.By suppressing the ripples that occur at the mouth of the cylindrical case, it is possible to cut edges in the subsequent process. It is possible to obtain a cylindrical case with a stable height dimension without cutting, and since there is no edge cutting, there is no scrap and the material yield can be 100%, reducing the number of processes and material costs. It has the effect of increasing productivity.

れ、これによって円筒ケース１２の高さは一定となる。DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 4 to 6. In the figure, 8 is a punch for forming, 9 is a die that receives it, 10 is a knockout bin for ejecting the product, and 11 is a stripper. The punch 8 moves the sent billet 1 in the direction of the arrow Y as the press device is driven, pinches it between the billet 10 (knocker) 10, and, together with the guide of the tapered part F, falls into the round hole G drilled in the die 9. The cylindrical case 12 is formed by applying a predetermined pressure to the cylindrical case 12. At this time, the mouth of the case is pressed against the tapered part of the punch 8, and thereby the height of the cylindrical case 12 is kept constant.

品を得るものである。When the forming is completed, the punch 8 moves in the Y direction, but at this time, a gap is provided to prevent the material of the cylindrical case 12 from flowing between the punch 8 and the die 9, making it difficult for the punch 8 to move. be. As the punch 8 moves, the cylindrical case 12
After the knockout 1° has completely moved in the Y direction, the material stuck to the punch 8 is removed by a stripper 11 to obtain a product.
