摘要： A handheld punch tool includes a housing defining a first axis, a motor contained within the housing, the motor having a motor shaft defining a second axis, and a head coupled to the housing. The head including a drive member reciprocable along a third axis in response to rotation of the motor shaft about the second axis, and a punch coupled to the drive member and reciprocable in response to reciprocation of the drive member along the third axis. The handheld punch tool further includes a debris collection container removably coupled to the head. The debris collection container is configured to receive chips generated during operation of the handheld punch tool.

摘要： A cable cutter includes stationary and moveable clamps, each comprising a respective pivot opening and a cutting edge spaced from the pivot opening. A pivot joint connects the clamps to allow the movable clamp to pivot about a pivot axis relative to the stationary clamp. The pivot joint includes a threaded connector having a head and a shank extending from the head along the pivot axis through the pivot openings in the clamps. A collar has opposing faces and an opening extending through the collar. A nut is threaded on the shank and the clamps are sandwiched between the head and the collar with the head adjacent one of the clamps. The collar is engaged to rotate with the shank the about the pivot axis.

摘要： A cutting device capable of obtaining high speeds, approximately three times faster than known cutting devices by using a structure employing an internal positive cam. A rotary slider rotates upon rotation of a spline shaft via a gearbox, and the operation is such that a track of a wedge-shaped blade tip of a male cutter lies along a workpiece via cam followers slidably rotating over a sliding surface of an internal positive cam, cutting the workpiece.

摘要： A manually-operated rule bending and notching press producing a ram output mechanical advantage that is substantially than prior art manual rule bending and notching presses. This is accomplished by providing a toggle linkage that drives a crank-and-pivot mechanism. The input handle is able to travel through at least about 100 to 180 degrees of rotation as the ram moves through its full travel, however, the handle still moves through the most usable 90 degrees of rotation while the ram is moving through the most highly loaded final 1/2 to 3/4 inch of its stroke. The crank and pivot mechanism provides a substantially linear force multiplication during this last part of the press ram stroke because the crank does not pass or near the top dead center of either the input or the output linkage. Accordingly, variations in output mechanical advantage may be effected simply by altering the radii of the input and output crank pivots.
摘要翻译：一种手动操作的规则弯曲和开槽冲压机，其产生了比现有技术的手动规则弯曲和切口压力机大得多的压头输出机械优点。这是通过提供一种驱动曲轴和枢转机构的肘节连杆来实现的。输入手柄能够通过至少大约100至180度的旋转，因为柱塞移动通过其全部行程，但是手柄仍然移动通过最可用的90度旋转，同时压头移动通过最高负载最终+ E，fra 1/2 + EE至+ E，其中风3/4 + EE英寸。曲柄和枢转机构在压力机冲程冲程的最后部分提供基本上线性的力倍增，因为曲柄不通过或接近输入或输出连杆的上止点。因此，可以简单地通过改变输入和输出曲柄枢轴的半径来实现输出机械优点的变化。

摘要： The vertically reciprocal upper blade assembly of a sheet metal squaring shear is activated in a substantially vertical path past a fixed lower blade by means of one or more reciprocal rotary hydraulic actuators. The output drive shaft of the hydraulic actuator(s) is connected to one or more drive straps by an eccentric cam which is keyed to the drive shaft and rotatably received within the straps. The horizontal gap between the upper blade and the lower blade is precisely controlled by suspending the blade supporting gib bracket from pins on the side walls of the apparatus housing and adjustably connecting the gib plate to the pins by eccentric cams. The gib mounting system also provides for adjusting the angle of the upper blade with respect to the lower blade. An improved hold down assembly limits the stroke of the hold down pins to maintain a slight clearance between the hold down pins and the bed surface at all times. A unique hydraulic actuator mounting bracket facilitates alignment of the actuator with the drive shaft by permitting adjustment of the actuator relative to the shaft after the shaft is properly mounted and aligned in the machine frame.

摘要： The invention relates to a pair of shears for shearing sheet metal. Known shears, for example power shears, require relatively great forces, which cannot be produced except by special gear means. For rendering it possible to manually shear even relatively thick sheets, according to the invention it is proposed that the movable blade (22) of the shears is connected to a drive mechanism (13,15,17) and is located above the stationary blade (6) of the shears in its starting position for shearing, and that the drive mechanism is supported in the stand (1) of the shears for vertical movement, whereby the dead load of the drive mechanism and of the movable blade is utilized by gravity action for the shearing work.
