The machine bed includes left and right sidewalls. The driving unit is disposed at an inner side of the left sidewall. The sliding seat unit is disposed at an outer side of the right sidewalls, and includes a sliding plate unit that can reciprocate forwardly and rearwardly to activate a cutting unit and a holding unit. The sliding plate unit is guided by a guiding roller mechanism such that the sliding plate unit moves smoothly.

Abstract: A pneumatic or manual impact operated nailer requires fasteners in a clip, typically of about 100 fasteners. The invention provides uniform well-bonded fasteners in a clip for use in a pneumatic or manual nailer, the clips being adhesive-free. In addition, this invention provides a method and apparatus for manufacturing such adhesive-free clips by press-forming the fasteners, placing them in proper orientation in a fixture on a rotatable turret rotating the turret to a spot welding location, spot welding the fasteners, and rotating the turret to a clip unloading station. The clip product is also disclosed.

Abstract: A handling apparatus for forging machines, especially for advancing a wire intended for the manufacture of screws, rivets and the like includes a first cam, keyed on a first motor-driven rotary shaft, cooperating with a first angularly orientable lever, associated with a roller and formed by a branch having a rectilinear portion, oriented parallel with respect to a screw, guided by a support and caused to rotate alternatively clockwise and counter-clockwise either by an electric motor or by hand; a sliding carriage, associated with the screw, provided with a transversal tying pin for an oscillating bar having on its free end a needle that strikes the rectilinear portion of the first lever; a second angularly orientable lever, cooperating with a carriage that is movable in a direction parallel to the direction of advance of the wire; wire grasping means for grasping the wire; a second cam, alternatively mounted on a second shaft or a rotary side shaft of the forging machine, which cooperates with a needle fixe

Abstract: A reciprocating mechanism includes a seat body, a longitudinal first slide member, and a second slide member. The seat body has therein a longitudinal first guiding groove, a second guiding groove intersecting the first guiding groove, and a crossing space at the intersection of the first and second guiding grooves. The first slide member is disposed slidably and reciprocatingly in the first guiding groove across the crossing space, and has a longitudinal cam member extending longitudinally of the first slide member. The second slide member is mounted slidably on the seat body along the direction of the second guiding groove, and incorporates a cam follower which extends into the crossing space to contact the cam member. The cam follower is movable to-and-fro along the second guiding groove when the cam member reciprocates along the first guiding groove, thereby moving reciprocatingly the second slide member along the second guiding groove.

Abstract: A transfer apparatus for use in a press in which successive workpieces are sequentially transferred from one to the next of a plurality of working stages arranged along a line. The transfer apparatus has a transfer bar having a plurality of workpiece holding devices such as air chucks each being capable of holding and releasing the workpiece, and a driving unit provided at the rear side of the press.

Abstract: A machine makes nails having a star-shaped transverse cross-section by sequentially feeding conventional nails into a form roller station defined by a plurality of form rollers that are radially arrayed with respect to a centerline of the nails. Circumferentially spaced notches formed about the periphery of each form roller engage the heads of the conventional nails as the form rollers rotate and pull the nails into forming relation with the form rollers. The notches also prevent formation of the nail heads. A plurality of circumferentially spaced concavities formed in the form rollers prevents forming of the work-hardened points of the nails. The nails are sequentially delivered from a bowl feeder to an indexer that inverts the nails. A pair of rotatably mounted augers transfer the nails from the indexer to a nail-gripping device that holds each nail until its head is engaged by the nail-engaging notch in each of the form rollers.

Abstract: A transfer arrangement for a multistation press has two parallel gripper rails on a carrier and can be moved, together with the carrier, along a transfer curve. The gripper rails carry gripper fingers which are assigned to one another in pairs and which can be moved toward and away from one another by an oppositely directed movement of the gripper rails. The application movement is generated by parallelogram transmissions which are used for the bearing and for the drive of the gripper rails. The parallelogram transmissions are driven from a single drive source by a cardan shaft which permits the implementation of the transfer movement without any change of the relative position of the gripper fingers with respect to one another. Such a transfer arrangement is arranged on one side of the row formed by the tools and permits good access to the workpieces from the respective other side. As required, the entire transfer arrangement can be removed from the tool area, preferably in a swivel movement.

Abstract: A progressive forging machine having automatically adjustable cam timing for transfer finger opening and closing movement and for knockout pin action. The cams can be adjusted without manual effort to thereby reduce changeover time and the level of skill required to effect a changeover. For each of the transfer finger and knockout actions, a separate cam assembly is provided with a series of cam sections that are selectively repositionable on a common shaft by appropriate operation of a corresponding series of cam stop actuators and a common clutch actuator.

Abstract: A transfer mechanism for a progressive forging machine in which the fingers for transporting workpieces from station to station are arranged to pick the workpieces axially out of dies from which they are being discharged, transfer the workpieces laterally from the discharging stations to receiving stations, place the workpieces axially into the receiving stations, and then open wide enough to clear tooling on the slide and return to the original delivery stations. Included in the mechanism is an adjustment for the axial stroke of the fingers and a cassette mounting for the fingers enabling them to be readily replaced with another cassette for a changeover in the workpieces being forged.

Abstract: The turning device has a guideway (13) which is formed integrally on the tong carrier (3) and in which is guided the roller (16) of an oscillating lever (15). The reciprocating movement of the guideway (13) is transmitted via the oscillating lever (15) to a pivot pin (14). The latter turns the portion (A) in conjunction with a counter-holder (22). The turning device is used on horizontal cross-transfer presses having a high production rate for metal forming starting from portions of wire.
