摘要： A flat die thread rolling machine provides a cam drive for the reciprocating slide (18) which operates through a linkage to cause reciprocation of the slide. The cam provides a dwell which holds the reciprocating die (78) stationary before the commencement of the working stroke to allow insertion of a workpiece into the dies (73,78) while the dies are stationary relative to each other. The cam produces slow acceleration of the reciprocating die (73) during the initial portion of the rolling operation to prevent workpiece slippage. The working stroke exceeds one-half of the machine cycle. Die match can be adjusted while the machine is running. Separate adjustment means are provided to adjust the tilt, parallelism, and pitch of the dies, with the pitch adjustment permitting pitch adjustment while the machine is running and without affecting tilt and parallelism adjustment. A hydraulic drive is provided to power the machine and provide high torque during jog operations and speed control during normal running operation.
摘要翻译： 平模切丝机提供用于往复运动滑动件的凸轮驱动器，其通过连杆操作以引起滑块的往复运动。 凸轮提供驻留，其在工作行程开始之前保持往复式模具固定，以允许模具相对于彼此固定而将工件插入模具中。 在滚动操作的初始部分期间，凸轮产生往复式模具的缓慢加速以防止工件滑动。 工作冲程超过机器周期的一半。 模具匹配可以在机器运行时进行调整。 提供分离的调节装置来调节模具的倾斜度，平行度和间距，在机器运行时，俯仰调节允许俯仰调节，并且不影响倾斜和平行度调节。 提供液压驱动器为机器供电并在点动操作期间提供高扭矩，并在正常运行操作期间提供速度控制。

摘要： A progressive former having quick-change tooling provides tooling supports (36) with means for adjusting the tools. The tooling is mounted so that the tooling and the structure for adjusting the tooling (36) can be removed as units without loss of the fine-tuning of the adjustments and so that reinstallation does not require readjustment of the tooling. A transfer (102) also provides adjustable cams (132, 133) for opening and closing gripper fingers (107) which transport workpieces from one work station to the next. The adjustable cams (132, 133) are removable with the dies as units and can be reinstalled without further fine-tune adjustment. With the invention, entire tool sets (36) can be changed in a very short time to eliminate loss of production capacity of the machine. Similar sized machines are provided with a fixed spacing between the locating surfaces (49, 48) (86, 84) for the stationary dies and the reciprocating tools so that tool sets having adjustments fine-tuned in one machine can be installed in a similar machine without further retuning of the readjustments.

摘要： A progressive former and method of producing progressive formers is disclosed in which the bed frame (10) is formed of two side frame members (11, 12) and a spacer member (13). The two side frame members (11, 12) and the spacer member (13) are substantially fully machined before the side frame members (11, 12) are assembled on opposite sides of the spacer member (13). Within a given machine size, the side frame members (11, 12) are identical and the width of the spacer member (13) is adjusted to provide the proper spacing between the side frame members (11, 12) for the particular number of work stations in a given machine. By utilizing component parts to produce the machine bed frame (10) rather than a one-piece casting, substantial cost savings are achieved. Further, since the side frame members (11, 12) are identical in machines of a given size having different numbers of work stations, it is economically feasible to produce side frame members (11, 12) for inventory and then assemble them with an appropriate spacer member (13) to provide the desired number of work stations. Similar economies are achieved by utilizing similar kickout drives (81) in timed knockout drives at each work station. The slide (68) and the die breast (73) are laterally located with respect to one of the side members (11, 12) so that tolerance and thermally-induced variations in the spacing between side frame members (11, 12) do not adversely affect the alignment of the slide (68) and the die breast (73).
摘要翻译： 公开了一种生产渐进式成型机的渐进式成型机和方法，其中床架（10）由两个侧框架构件（11,12）和间隔构件（13）形成。 在侧框架构件（11,12）组装在间隔构件（13）的相对侧上之前，两个侧框架构件（11,12）和间隔构件（13）基本上完全加工。 在给定的机器尺寸内，侧框架构件（11,12）是相同的，并且间隔构件（13）的宽度被调节以在侧框架构件（11,12）之间为特定数量的工件提供适当的间隔 给定机器的站。 通过利用组件来生产机床架（10），而不是一体式铸件，实现了大量的成本节约。 此外，由于在具有不同数量的工位的给定尺寸的机器中侧框架构件（11,12）相同，因此生产用于盘存的侧框架构件（11,12）在经济上是可行的，然后以适当的方式组装它们 间隔构件（13）以提供所需数量的工作站。 通过在每个工作站的定时击倒驱动器中使用类似的脱扣驱动器（81）来实现类似的经济。 滑动件（68）和模具乳房（73）相对于侧部构件（11,12）中的一个侧向定位，使得侧框架构件（11,12）之间的间隔的公差和热诱导变化不 不利地影响滑块（68）和模具乳房（73）的对准。
