摘要： A punching apparatus is provided with a tool holder that has integral upper and lower arms. The upper and lower arms are provided with punches and dies, respectively. In one form, a smaller punch and die set is spaced longitudinally behind a larger punch and die set and laterally offset in a direction toward the work sheet clamps. In another form, the smaller punch and die set is spaced longitudinally forward in a direction toward the work sheet clamps and laterally offset from the larger punch and die set. The tool holder is extendable longitudinally and laterally to accurately align either the large punch and die set or the smaller punch and die set beneath a striker. In one form, the upper arm is recessed closely adjacent the smaller punch to reduce interference with the work sheet clamps. In both forms, the tool holder can also be extended further to a tool changing position.
摘要翻译： 冲孔装置设有具有整体的上臂和下臂的工具架。 上臂和下臂分别设有冲头和模具。 在一种形式中，较小的冲头和模具组在较大的冲头和模具组之间纵向间隔开，并在朝向工件夹具的方向上横向偏移。 在另一种形式中，较小的冲头和模具组件在朝向工件夹具的方向上纵向前进地间隔开并且横向偏离较大的冲头和模具组。 工具架可以纵向和横向延伸，以精确地对准大冲头和模具组，或将较小的冲头和模具组合在冲头下方。 在一种形式中，上臂与较小的冲头紧邻地凹入，以减少对工作夹具的干扰。 在这两种形式中，工具夹具还可以进一步延伸到换刀位置。

摘要： A punch press is provided with turrets having radially spaced tools and a radially shiftable striker for selectively engaging the tools. The striker is carried by a transport mechanism which is shifted by powered means and is vertically slideable relative to the powered means. The powered means include two radially spaced cylinders each containing a piston. A fixed piston rod is connected to the radially inner piston and a moveable piston rod is connected to the radially outer piston and to the transport means. Accurate positioning of the striker is obtained by controlling the relative positions of the pistons and cylinders. The transport means holds the striker for free relative upward movement. A shear plate is positioned over the striker and a backup plate is positioned over the shear plate. The backup plate contains openings for receiving a slug cut from the shear plate by the striker to relieve the striker when overloaded.

摘要： A side feeding shearing apparatus is provided with an upper frame having a side opening to allow sheets to be swung between the shear punch and die to position the sheet for feeding past the shear punch. The shear punch is positioned below the sheet supporting surface of the shearing apparatus and is raised for shearing the sheets. Sheets are delivered to the shearing apparatus by a transfer mechanism that includes a base secured to an adjacent N.C. punch press. An arm which clamps the sheet is pivotally mounted on the base and the arm is accurately aligned on the base by a shot pin and corresponding aperture. Movement of the sheet through the shearing apparatus is provided by the sheet positioning means of the N.C. punch press.

摘要： A punch drive converts rotary motion from a power source in one embodiment into one-speed reciprocation or in another embodiment into selective two-speed reciprocation of a punch. In the latter embodiment the slower speed of reciprocation is provided by rolling a plurality of primary thrust balls between a rotating gear and a reciprocating primary wave thrust ring. The wave thrust ring has three cam waves which cause the thrust ring to be reciprocated downwardly as the balls roll thereover. The thrust ring is coupled through a clutch mechanism to the punch. The second speed is provided by a rotatable nibbling drive collar and a reciprocating nibbling wave thrust ring having a plurality of nibbling thrust balls therebetween. The nibbling wave thrust ring is provided with nine cam waves which cause reciprocation of the nibbling wave thrust ring as the thrust balls are rolled thereover. The nibbling wave thrust ring is also coupled to the punch. The rate of downward movement of the thrust rings is determined by the slope angles of the forward surfaces of the cam waves.
摘要翻译： 打孔机将一个实施例中的动力源的旋转运动转换为一速往复运动，或者在另一个实施例中转换为冲头的选择性两速往复运动。 在后一个实施例中，较慢的往复运动速度是通过在旋转齿轮和往复式主波推力环之间滚动多个主推力球而提供的。 波浪推力环具有三个凸轮波，当滚珠滚动时，该凸轮波使得推力环向下往复运动。 推力环通过离合器机构联接到冲头。 第二速度由可旋转的啃咬驱动轴环和往复式啃咬波推力环提供，该推力环在它们之间具有多个啃咬推力球。 冲击波推力环设有九个凸轮波，当这些推力球在其上滚动时，它们会引起冲击波推力环的往复运动。 冲击波推力环也与冲头相连。 推力环的向下运动速度由凸轮波前表面的倾斜角决定。

摘要： A pneumatic-hydraulic control is coupled with either a manually or numerically controlled punch press to rotate the turrets of the press to the proper positions. Pneumatic pressure is directed selectively to one of two fluid accumulators to force fluid from that accumulator through an open deceleration valve to drive a piston which in turn is coupled to a rack and pinion drive for rotating the turrets. The other side of the piston is exhausted through an open deceleration valve to the other fluid accumulator. A slider switch having a central stop contactor and two deceleration contactors is secured to the rack and moves with the rack across a linear multi-contact slidebar. One of the contactors on the slidebar corresponding with the desired station on the turret is energized. A deceleration contactor engaging the energized contact closes the deceleration valve of the driving fluid accumulator forcing the fluid to go through a restricted passage thus decelerating the turret drive. The stop contactor engaging the energized contact exhausts both fluid accumulators to stop the turret drive.
摘要翻译： 气动液压控制与手动或数字控制的冲压机相结合，以将压机的转塔旋转到正确的位置。 气压被选择性地引导到两个流体蓄积器中的一个，以迫使来自该蓄能器的流体通过打开的减速阀来驱动活塞，活塞又连接到用于旋转塔架的齿条和小齿轮驱动器。 活塞的另一侧通过打开的减速阀排放到另一个液体蓄能器。 具有中央停止接触器和两个减速接触器的滑动开关固定到机架上，并与机架一起移动穿过线性多接触滑动杆。 与刀架上的所需工位相对应的滑块上的接触器中的一个被通电。 接合通电接触器的减速接触器关闭驱动液体蓄能器的减速阀，迫使流体通过限制通道，从而使转塔驱动器减速。 接合通电接触器的停止接触器排出两个流体蓄积器以停止转塔驱动。

摘要： A folding apparatus is provided with a pivotal folding punch that moves past a work sheet supporting surface and an anvil. Hydraulically powered piston and cylinder mechanisms pull the anvil against the work sheet supporting surface while simultaneously pulling the punch about the anvil. Second hydraulic cylinder and piston mechanisms provide a variable resistance force against the movement of the punch.
