摘要: A method of producing seamless cans wherein a blank holder 2 is inserted in a metal cup 5 coated with an organic film 12, a punch 1 is advanced into a cavity 7 in a die 3 while pushing the bottom 5a of the metal cup onto the flat surface portion 3a of the die by the blank holder 2, so that the side wall 5b of the metal cup 5 is brought into intimate contact with the flat surface portion 3a of the die and with the working corner 3b having a small radius of curvature, thereby to reduce the thickness of the side wall 5b by bend-elongation. Moreover, the portion to be subjected to the necking is ironed at an ironing ratio of not smaller than 5% by the punch 1 in cooperation with the front end 3b.sub.1, of the working corner 3b, or by the front end 3b.sub.1, and an ironing portion of a short cylindrical portion in front thereof, or by the punch 1 in cooperation with the ironing portion 3g of the die 3 by advancing the side wall 5b slightly toward the inside in the cavity 7, thereby to obtain a seamless can 20 having a reduced thickness in the side wall 5b. This method makes it possible to control the thickness distribution in the side wall and, hence, to produce seamless cans having reduced thickness in the side wall permitting the organic film to be least whitened during the necking working.

摘要: In a method for forming a barrel for a two-piece can, before the step of draw-forming the bottom, a taper portion having an inner diameter gradually decreasing toward the bottom surface is formed on a lower part of the side wall of a flat-bottom barrel, corresponding to the outer circumferential frustoconical portion of the bottom of the final barrel or an upper portion contiguous to the outer circumferential portion, and at the step of draw-forming the bottom, at least an upper part of the taper portion is outwardly expanded by insertion of the cylindrical punch. According to this method, a two-piece can having a bottom having a good appearance, a high pressure-resistant strength and an excellent corrosion resistance can be prepared at a high productivity and with a good operation adaptability.

摘要: A draw-forming method in which a disc-like metal sheet having an organic film or a cup made of a metal sheet having an organic film is held by an annular holder member and a drawing die, and a drawing punch and the drawing die are moved in mesh with each other and relative to each other, the drawing punch being so provided as to move into or cut of the holder member in concentric with the holder member and the drawing die, wherein at least either one of the annular holder member or the drawing die that had been pushing a residual flange portion is so moved as to discontinue the pushing just before the draw forming is finished in said drawing step, and the flange portion is drawn while liberating the rear end of the flange portion. This makes it possible to eliminate the defects inherent in the conventional draw-forming method or the draw/redraw-forming method, and to draw-form a metal sheet having an organic film into a flangeless cup without developing pinching, film hair or enamel hair at the upper portion of the cup, without causing the can barrel or the organic film to be broken during the drawing, and without permitting the tools that are used to be worn out or damaged, but maintaining excellent operation efficiency.

摘要: A vibration damping bushing including: an inner axial member; an outer cylindrical member through which the inner axial member is inserted; a main rubber elastic body elastically connecting the two members; and a stopper member that is fitted onto the inner axial member as a component of a first stopper mechanism that limits relative displacement of the inner axial member against the outer cylindrical member to one side in an axial direction. The inner axial member is formed with a latching depression that opens toward an outer periphery thereof, and the stopper member is provided with a latching piece that protrudes outward in the axial direction. The latching piece is engaged with the latching depression so as to provide a slipping out prevention mechanism for preventing the stopper member from slipping out from the inner axial member.
