    • The present invention provides a redrawing method which comprises holding a preliminarily drawn cup of a covered metal sheet by an annular holding member inserted in the cup and a redrawing die, and relatively moving the redrawing die and a redrawing punch arranged coaxially with the holding member and redrawing cup, the drawing punch being capable of going into the holding member and coming out from the holding member, so that the redrawing die and redrawing punch are engaged with each other, to form a deep-drawn cup having a diameter smaller than that of the preliminarily drawn cup. This redrawing method is prominently characterized in that the radius of curvature of the operating corner portion of the redrawing die is 1 to 2.9 times as large as the bare sheet thickness of the metal sheet. According to this redrawing method, the thickness is effectively reduced by bending anad elongating of the side wall, and the variation of the thickness between the upper and lower portions of the side wall is eliminated and the thickness is uniformly reduced as a whole.
    • 本发明提供一种重画方法,其包括通过插入杯中的环形保持构件和重画模具来保持被覆盖的金属片的预先拉拔的杯,并且使重画模具和与保持构件同轴设置的重画冲头相对移动, 重画杯,拉拔冲头能够进入保持构件并从保持构件中脱出,使得重画模具和重新拉伸冲头彼此接合,以形成直径小于 初榨杯。 该重画方法的特征在于,重画模具的操作角部的曲率半径为金属片的裸片厚度的1〜2.9倍。 根据这种重画方法,通过弯曲侧壁的伸长来有效地减小厚度,并且消除了侧壁的上部和下部之间的厚度的变化,并且整体上均匀地减小了厚度。

    • 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.
    • 一种拉伸成形方法,其中具有有机膜或由具有有机膜的金属片制成的杯状的盘状金属片由环形夹持构件和拉伸模具保持,并且拉拔冲头和拉拔模具 彼此相对移动并且相对于彼此移动,所述拉伸冲头被设置成与保持器构件和拉伸模具同心地移动进入或切割保持器构件,其中环形保持器构件中的至少一个或 推动残留凸缘部分的拉伸模具被移动,以在拉拔步骤结束之前中止推动,并且在释放凸缘部分的后端的同时拉出凸缘部分。 这使得可以消除传统的拉伸成形方法或拉伸/再拉伸成形方法中固有的缺陷,并且可以将无机膜的金属板拉伸成无凸缘的杯状物,而不会产生夹持,薄膜毛发或搪瓷毛发 在杯子的上部,不会在拉拔期间导致罐筒或有机膜破裂,并且不允许使用过的工具被磨损或损坏,而是保持优异的操作效率。
