摘要:
The object of the present invention is to provide a turret punch press capable of discharging easily the small article work sheet cut off from the material work sheet, without employing a subhead separately from the punch driving mechanism. The punch press comprises a work sheet outlet 12 for discharging small article work sheet cut off from the material work sheet in the punch processing, employed in the lower turret 4. Moreover, a chute 13 connected to the work sheet outlet 12 is employed in a main body frame 1.

An automatic cutting and stacking device for arcuately shaped blanks is disclosed. The device contains a feeding table followed by a cutting unit and a stacking device. The cutting unit is movable in relation to the feeding table to thus allow a cutting perpendicular to the contour of the shaped film. The stacking unit comprises a slide plate and a movable base plate upon which the cut blanks are stacked. The height of the base plate can be adjusted/lowered in relation to the accumulating thickness of the stacking height of the cut blanks.

Web or sheet-fed segment processing apparatus (30, 300) is provided for high speed, extremely accurate operations such as die cutting or lamination. The apparatus (30, 300) includes a processing station (32, 300) adapted to receive a segment (38) forming a part of a continuous web (100, 102) or as a discrete sheet. The station (32, 300) includes a vacuum hold-down plate (142, 306) for holding initially fed segments (38); the hold-down plate (32, 308) is shiftable as necessary along orthogonal X-Y axes in the plane of the segment (38), and/or null rotation about a rotational axis transverse to the segment plane, such movement being effected by a series of aligned, translatable eccentric drive units (178-182, 346-350) coupled with plate (142, 306). Preferably, the segments (38) carry positioning fiducials (44) and which are compared with fixed reference indicia (250, 252) in the station (32, 300). Such comparison data is used by a controller (254) to generate the necessary movement information used in simultaneous operation of the associated plate drive units (178-182, 346-350).

An adjustable angular shearing device (10) in accordance with the invention is adapted to transversely shear sheet material from a continuous strip in a punch press. The device (10) has an upper punch (24) which coacts wtih a lower die (28) to shear sheet material passing between them. The punch (24) comprises a pair of members (32, 34) which coact with a pair of corresponding members (74, 76) on a lower die (28). The members rotate about aligned posts (26, 30) at the vertex of an angle. The rotation of the members about each respective post is selectively adjustable. A chevron-shaped part can be stamped from a continuous strip of sheet material by two successive stamps of the punch press.

A programmable controlled turnblanking machine comprising a blanking apparatus having a pair of blank dies each provided with a cutting edge and disposed in a strip feed direction on a bed to cut out blanks of predetermined shape and size from a strip by means of the cutting edges of the blank dies, one of the blank dies being disposed in front in the strip feed direction and preventing from sliding in the strip feed direction, and the other blank disposed in the rear in the strip feed direction so as to be slidable on the bed in the same direction, both blanked dies being rotatably supported on the bed; a teaching unit for inputting a slide distance X of the rear blank die as well as rotational angles .theta..sub.1 and .theta..sub.2 of both front and rear blank dies and setting positioning data for the blank dies as program data; and a control box for automatically setting initial positions of the paired blank dies in accordance with a program based on the said program data set by the teaching unit and controlling blank cutting operations of the blanking apparatus automatically.
摘要:
A punch press has a ram assembly with a lower portion which is rotatable and reciprocatable about a vertical axis and, a die holder which is rotatable about the same axis. A gear mechanism is coupled between a drive motor and the lower portion of the ram assembly and the die holder to effect simultaneous rotation thereof, which effects reorientation of the tooling relative to the X and Y axes of the punch press. In this fashion, rotation of the tooling will enable a single set of tooling to effect cutouts of different orientation in a workpiece relative to the X and Y axes, and movement of the sheet material along the X and Y axes together with such rotation of the tooling enables complex configurations to be nibbled or cutout with a limited number of sets of tools.

In a notching machine using a blade assembly of upper and lower knives mounted respectively on a vertically moving ram and a machine table and each comprising two individual blades forming with their cutting edges a coinciding vertex angle which may be changed by turning the blades relative to each other around a vertical axis of rotation that extends in parallel with the ram near the noses of the knives, a third blade component is provided at least for the upper knife for forming its nose portion with a unitary cutting edge that complements the cutting edges of the two other blades of the upper knife for confining its vertex angle.
摘要:
A blanking shear machine has a rotatable upper turret having a holder for an upper blade. The upper blade has two contiguous sides which form a right angle therebetween. A rotatably mounted lower turret has a holder for a lower blade which corresponds to the upper blade. Means for clamping and positioning a workpiece are provided between the upper and lower turrets. The turrets are rotated to position the blades to provide the desired cut. A plurality of strikers are provided above the upper turret at four positions above the upper blade at which the contiguous sides of the blade are aligned with the X-axis and Y-axis coordinates. Means for actuating the strikers are provided to lower the upper blade to engage the lower blade, shearing the workpiece between the two blades.
