Abstract: A punching tool for attaching adjacent steel deck panels along a side-lapped seam positions first and second jaws on one side of the seam, and positions third, fourth and fifth jaws on the other side. An actuator compresses the two sets of jaws; blades on the ends of such jaws shear the seam to create two louvers extending in one direction separated by a third louver extending in the other direction. The first jaw blade passes between the third and fourth jaw blades, and the second jaw blade passes between the fourth and fifth jaw blades. The blades are tapered to prevent binding upon release. The blades may include semi-cylindrical punching portions, and can be formed as detachable inserts coupled to the jaws, as by dovetail joints. The jaws may be made of a metal having a hardness rating less than that of the detachable blade inserts.

Abstract: The invention relates to a compression tool (2) for the permanent connection of workpieces (14, 16, 18, 30, 34) having two pivot elements (4), which each have a compression jaw (10), and having at least one rotational axis (6), on which the pivot elements (4) are hinged, wherein the inner contours of the opposing compression jaws (10) form a receiving area (12). The present invention is based on the technical problem of disclosing an alternative compression tool (2), with which a permanent connection can be provided between workpieces (14, 16, 18, 30, 34) by axial compression. The technical problem is solved in that the inner contours have at least one sliding face (22), which is inclined relative to the receiving area axis (20). A compression tool (2) can thus be provided which, starting from a radial inward movement, performs a compression in the axial direction, nonetheless requires little installation space, and offers weight advantages due to a smaller axial extension, for example.

Abstract: A method and a device for bending a metal hollow thick walled member to a predetermined angle without deviation of the bending center position and without separation from a half die when presser die moves up. With a pair of guide plates (GP1 and GP2) turnably attached to a center pin CP kept horizontal and the axis center of the center pin intersecting with the axis center of the metal hollow thick walled member PM, the member PM is mounted on a half die (82a). When die holding members (80a and 80b) fixedly connected to the above guide plates and kept horizontal are inclined and separated from each other as the center pin lowers, the member PM is bent to the predetermined angle and held on the half die (82b). When the center pin that can be moved vertically by a guide member moves down to a predetermined position, a contact portion (96b) contacts the inclined surface of a stopper (92b) to allow a base plate (16) to receive a pressing force from an upper die via the stopper.

Abstract: A tool for cutting a live electrical wire and applying a connector thereto in a safe and convenient manner has a housing with a pistol grip and actuating means on a first end and wire preparing and connector application means at the opposite second end. At least the housing is made of electrical insulating material.

Abstract: A power assisted combination shear used for forming structural louvers in the crimped seam of structural steel decking comprises a frame supporting a pair of jaws which are opened and closed by means of an operator-controlled pneumatic cylinder. One jaw terminates in a blade and the other jaw has a corresponding die member.

The louver comprises a sheared portion in the form of a bowed tab bridging a corresponding window formed in the seam by the shearing of the tab. The interference between the louver and window provides a substantial increase in the lateral resistance (shear strength) of the crimped seam, thereby obviating the need to additionally weld or screw the seam to provide the necessary shear strength for even the highest stress applications.
