Abstract: A plate rolling mill includes a pair of work rolls that hold and press down a plate material therebetween, a plurality of backup rolls that prevent the work rolls from being deformed, and intermediate rolls each of which is disposed between the work roll and the backup roll so as to be shiftable. Each of the intermediate rolls has a contact roll portion that contacts with the backup roll, and an extension barrel portion that is connected to an end of the contact roll portion and does not contact the backup roll at any shifted position. The contact roll is formed to have a convex shape such that a convex center of the contact roll is positioned at a side of the extension barrel portion.

Abstract: When an actuator is operated, an upper die is displaced downwardly, pressing a lower surface of a workpiece against a forming surface. After the upper die is displaced upwardly, an ejecting member is displaced upwardly to push the workpiece upwardly by a lower die. As the workpiece is displaced upwardly, an outer circumferential surface of the workpiece is squeezed by a squeezer projecting radially inwardly from an inner circumferential surface of an outer ring.

Abstract: A core bar for bending of a pipe and a method of bending of a pipe are provided whereby collapse of the pipe can be prevented and bending can be automated at low cost. Ends of the respective core bar portions are formed such that, when the ends of the two cylindrical core bar portions are engaged telescopically, and one core bar portion is bent at a desired angle with respect to the other core bar portion, the outside circumferential surface of the bending region that is formed by these core bar portions becomes a curved surface along the generating line.

Abstract: Linesman type pliers (10) that have provisions for splicing wires together. The pliers (10) have a right body (20) with a first jaw (22) on one end, and a handle (24) on the other end, and a pivotal bore (26) in-between. The first jaw (22) includes a truncated, tapered recess half (28) that is configured to receive an outward-extending stop and the provisions for gripping wire. A left body (32) has a similar jaw, handle, bore and truncated tapered recess half, except with an outward-extending stop (38) on the inner end. A pivot pin (42) is jointly disposed within bores (26) and (36), thus forming a solid-joint that arcuately swivels the right body (20) and left body (32) together into parallel and adjacent alignment. When the jaws are closed a complete, annular, truncated tapered recess (44) is formed that allows insertion of a number of stripped wires that form a twisted splice when the pliers are manually rotated around the stationary wires.

Abstract: A tie wrench for bending mounting clips to secure a fence wire to a fence post is disclosed. The tie wrench utilizes a hook that is positioned beneath the fence wire but above an outer portion of the mounting clip. The tie wrench is pulled toward the user to twist and secure the outer portion of the clip and the fence wire to the fence post. The other side of the clip is engaged and deformed in a similar manner by a flared finger that protrudes from the blade body of the tool. The large bend in the blade coupled with the small recess adjacent the exterior corner of the device seats the fence wire and produces a fencing tool that is easier and quicker to use compared to prior art devices.

Abstract: A method for manufacturing a seamless wheel rim includes the steps of deeply drawing a pre-cut circular aluminum alloy plate into a cup-shaped embryo body, punching out the bottom surface thereof to form a hollow cylinder, then putting it into an expanding-pressing female die with an expanding die cavity at both ends thereof respectively, and finally pressing and expanding both ends of the embryo body by two sets of expanding-pressing male dies to form a seamless aluminum wheel rim in sequence.

Abstract: A hydraulic rescue tool (20) that utilizes a hydraulic cylinder (22) having a piston rod (24) that is movably disposed within the housing of the cylinder to provide linear driving means for the rescue tool. A cylinder yoke (32) is rotatably attached to the hydraulic cylinder housing and includes a front handle bar (34) for manipulating the tool. Rotation of the cylinder yoke (32) relative to the cylinder (22) prevents injury to an operator in the event that the tool binds and torques. An implement unit (50), which is either a cutter (54) or a spreader (74), is detachably disposed onto the piston rod (24). Pivotal links (36) connect the unit (50) to the cylinder yoke (32), with the unit used for cutting or spreading metal during a rescue. A plurality of quick release pins (72) attach the implement unit (50) to the piston rod (24) and pivotal links, thus providing a rapid release of the implement unit (50) from the piston rod (24) and links (36) for replacement or repair.

Abstract: Wire-untwisting tools and tool bits are disclosed. The wire-untwisting tool comprises a tool body, a movable member, and a spring. The tool body has a first channel extending inwardly from a first surface and a second channel extending inwardly from a second surface. The movable member includes a third channel, and is positioned within the second channel to move therein between an open position, in which the first and third channels are substantially aligned and contiguous, and a gripping position, in which they are not. The spring bears between the tool body and the movable member so and biases the movable member toward the gripping position. A pair of twisted wires inserted into the aligned channels of the tool body and the movable member when the movable member is pushed into the open position will be gripped for untwisting when the movable member moves back to the gripping position.

In the lower die assembly in which a lower die is received and securely held in a die holder, the improvement comprises: a clamp means whereby the lower die when unclamped is received in the die holder so that the lower die can be extracted from the die holder upwards and then when clamped is securely held therein; and a lift means disposed below the lower die and whereby the lower die when unclamped is raised above an upper end of the die holder.

Abstract: An apparatus for manufacturing a band plate has a rolling mill that includes a pair of upper and lower work rolls that roll a slab material having edge drop portions at both ends thereof, and a pair of backup rolls that contact non-rolling side surfaces of the pair of upper and lower work rolls, respectively to prevent the work rolls from being deformed. The work roll includes a reverse taper portion where a roll diameter gradually increases towards a barrel end portion thereof corresponding to the edge drop portion. The upper and lower work rolls are configured to be shiftable individually in the axial direction thereof. The backup roll includes an escape portion whose diameter gradually decreases towards an axial end thereof so as not to contact the reverse taper portion of the work roll, within a shifting range of the work roll.
