    • Apparatus and method for trimming away a portion of the open end of an untrimmed can body to form a trimmed can body and a trimmed away portion using a plurality of can trimming apparatuses which are mounted on a turret which is secured to a main drive shaft for rotation therewith. Each of the can trimming apparatus has mechanisms for cutting the untrimmed can body to form a trimmed can body and a trimmed away portion; for separating the trimmed can body from the trimmed away portion by moving both in one axial direction and then only the trimmed can body in the opposite axial direction; for loading untrimmed can bodies onto each can processing apparatus and for unloading trimmed can bodies therefrom and for cutting, knurling and disposing of the trimmed away portions. A collapsibe mandrel is provided and comprises a hollow support member having a plurality of axially and radially outwardly extending resilient fingers integral therewith and a bearing surface mounted on an adjustable elongated hollow member in contact with the resilient fingers to control the radially outward extent thereof. Also, an annular spacer is located between a first knife and a first knurling roller to provide a space for the portion to be trimmed away prior to the knurling operation. A positive can body loading and unloading system is also provided.
    • 用于修剪未修剪的罐体的开口端的一部分的装置和方法,以使用多个可修剪装置形成修剪后的罐体和修剪部分,所述多个可修剪装置安装在转动架上,该转台固定到主驱动轴上 与其旋转。 每个可修剪装置具有用于切割未修剪的罐体以形成修剪的罐体和修剪掉的部分的机构; 用于通过在一个轴向方向上移动,然后仅在相对的轴向方向上仅修剪的罐体来将修剪后的罐体与修剪后的部分分离; 用于将未修整的罐体装载到每个罐加工装置上并用于从其中卸载修剪的罐体,以及用于切割,滚花和处理已修剪的部分。 提供了折叠式心轴,并且包括具有与其成一体的多个轴向和径向向外延伸的弹性指状件的中空支撑构件和安装在与弹性指接触的可调节细长中空构件上以控制其径向向外范围的支承表面。 此外,环形间隔件位于第一刀和第一滚花辊之间,以在滚花操作之前为要修剪的部分提供空间。 还提供了正罐体装卸系统。

    • A collapsible mandrel for use in holding a can body in a process wherein a portion of the can body having uneven edges on the open end thereof is trimmed away is provided and comprises a hollow support member having a longitudinal axis and mounted at a relatively fixed location and having a plurality of axially and radially outwardly extending resilient fingers integral therewith and an elongated hollow member mounted on the hollow support member to provide for linear movement therebetween. The elongated hollow member has a bearing surface in contact with the resilient fingers so that movement of the elongated hollow member varies the radially outwardly extent of the resilient fingers so that can bodies having inner peripheral surfaces of differing inner diameters may be readily moved over the resilient fingers but wherein the resilient fingers will exert a sufficient force thereon so that the can body will rotate with the resilient fingers. A movement limiting member is mounted within the resilient fingers so as to limit the radially inward movement of the resilient fingers. A locking device is provided to prevent the rotation of the elongated hollow member.
    • 一种用于保持罐体的可折叠芯棒,其中在其开口端具有不平坦边缘的罐体的一部分被修剪掉,并且包括具有纵向轴线并安装在相对固定位置的中空支撑构件 并且具有与其成一体的多个轴向和径向向外延伸的弹性指状物,以及安装在中空支撑构件上以提供它们之间线性运动的细长型中空构件。 细长的中空构件具有与弹性指状物接触的支承表面,使得细长的中空构件的运动改变弹性指状物的径向向外的范围,使得具有不同内径的内周表面的罐体可以容易地移动到弹性 手指,但是其中弹性指状物将在其上施加足够的力,使得罐体将随着弹性指状物旋转。 移动限制构件安装在弹性指状件内,以限制弹性指的径向向内移动。 提供锁定装置以防止细长的中空构件的旋转。

    • A redraw apparatus is provided for a can body making apparatus wherein the redraw carriage of the redraw apparatus is mounted for substantially friction-free sliding reciprocating movement over a pair of spaced apart support posts which are fixed mounted on the housing holding the can forming and ironing dies. Also, the counterbalancing system is provided for applying a force to counterbalance the weight of a portion of structures used to reciprocate the redraw carriage. Additionally, a ram assembly is provided for supporting a ram for movement through the redraw apparatus and the can forming and ironing dies wherein a pair of spaced apart elongated shafts are fixedly mounted and a ram carriage having the ram attached thereto is provided with liquid bearings using liquid coolant comprising water having solubles contained therein for mounting the ram carriage on the elongated shafts for substantially friction free movement thereover. A guide liquid bearing is also used to ensure proper alignment of the ram. Also disclosed is a reciprocating ram which is supported solely by a liquid bearing wherein the liquid bearing using liquid coolant comprising water having solubles contained therein has a sufficient length to ensure the proper alignment of the leading portion of the elongated ram as it engages a can blank in a redraw assembly and moves it through the forming and ironing dies to form an elongated can body.
