    • A can manufacturing device in which a tool supporting base has: a plurality of working tool units that support a plurality of working tools; a supporting member that supports a plurality of working tool units; and a linear driving mechanism that reciprocates the working tool units with respect to the supporting member in the axial direction of a workpiece. The linear driving mechanism has: a guide section fixed on the supporting member with a base plate therebetween; a slide rail that is fixed on the working tool unit and slides along the guide section; an electromagnetic coil provided on the base plate; a magnet plate that is provided on the working tool unit and generates, between the electromagnetic coil and itself, a thrust force for the guide section; and a supply pipe that is provided at the electromagnetic coil and supplies coolant to the inside of the electromagnetic coil.

    • A manufacturing apparatus for manufacturing a can having a can body including a dome section and an annular projection. The dome section is formed on a bottom of the can and is recessed inwardly of the can body. The annular projection is formed around a peripheral edge of the dome section so as to project outwardly in a direction of an axis of the can. A plurality of inner recesses are formed on an inner wall of the annular projection. The apparatus includes: an apparatus main body; a mandrel disposed on the apparatus main body for supporting the can body; a can bottom processing unit disposed on the apparatus main body so as to be relatively movable in the direction of the can axis with respect to the can bottom. The can bottom processing unit includes: a plurality of punch pawls having extreme ends which are disposed in a circumferential direction, which are movable in a radial direction, and which project toward the mandrel; a punch pawl expanding member which moves the extreme ends outwardly in the radial direction; and a dome support member which abuts the dome section from the inside of the punch pawls in the radial direction and supports the dome section. The apparatus produces a can having a reduced can bottom thickness, but still has a sufficient can strength without deformation of the can bottom and in which the phenomenon of bottom growth is suppressed.
    • 一种用于制造罐的制造装置,其具有包括圆顶部分和环形突起的罐体。 圆顶部分形成在罐的底部上,并且在罐体的内部凹入。 环形突起围绕圆顶部分的周边边缘形成,以便沿罐的轴线的方向向外突出。 多个内凹部形成在环形突起的内壁上。 该装置包括:装置主体; 设置在设备主体上用于支撑罐体的心轴; 罐底处理单元,其设置在设备主体上,以便相对于罐底可在罐轴线方向上相对移动。 罐底处理单元包括:具有沿圆周方向设置的端部沿着径向可移动并朝向心轴突出的多个冲头棘爪; 冲头棘爪扩张构件,其使前端沿径向方向向外移动; 以及圆顶支撑构件,其在径向方向上从冲压爪的内部抵接圆顶部分并支撑圆顶部分。 该装置产生具有减小的罐底厚度的罐,但仍具有足够的罐强度而不会使罐底变形,并且其中抑制了底部生长现象。
