A continuous strip of T-Nuts formed on a common strip of metal. Each T-Nut of the strip of T-Nuts is integrally connected to the next adjacent T-Nut by carry tabs. The carry tabs can be frangible themselves or contain a frangible portion. Each T-Nut includes a cylindrical bore therein and a threaded interior. A mechanism feeds and severs the endmost T-Nut in endwise fashion. The mechanism to feed and sever the endmost T-Nut includes a cutting blade positioned vertically below the frangible portion of the carry tab. A shearing ram having a guide positioned axially in line with the cylindrical bore in the endmost T-Nut is adapted to move vertically from an upper to a lower position to engage the cutting blade with the frangible portion and sever the endmost T-Nut.

The invention relates to a cable shearing apparatus and method for effectively cutting a cable from a rotatable drum, such as drilling line, boring line, electrical line, fiber optic line or the like. The cable shearing apparatus includes a cable management assembly having a track assembly and a clamp assembly, and a cable cutting assembly used in conjunction with the cable management assembly to manage, retain and sever a spent portion of the cable upon the drum.

A cutter includes an arc main body having a clamping groove in which a steel pipe may be putted, a plurality of bearings are mounted on the inner side of the main body, a fixed platform is arranged at the back end of the main body, a fixed block is fixed on the fixed platform, a lead-screw drive group penetrates the fixed block, the lead-screw drive group comprises a slide bar and a lead screw, the slide bar penetrates the fixed block, the lead screw is arranged on the slide bar and matches with the slide bar, a blade is mounted at the front end of the slide bar, the back end of the lead screw is connected with a gear drive group, the gear drive group is connected with a handle, and the fixed block is provided with a toothed fastener matching with a groove on the lead screw.

There is provided a cutting method for cutting a workpiece using a cutting tool comprising a die and a punch, including: arranging the workpiece between the die and the punch, and in a state in which a wedge-shaped first cutting part of the die and a wedge-shaped second cutting part of the punch are opposed, pushing the punch relatively to the die side to cut the workpiece; wherein: a front end angle 1 of the first cutting part and a front end angle 2 of the second cutting part are each 10 or more and 120 or less, and a front end radius R.sub.1 of the first cutting part and a front end radius R.sub.2 of the second cutting part are each 0.5% or more and 35.0% or less of a sheet thickness.

An auxiliary support device for a rolling-cut shear, including: a lower cutting table; a plurality of first hydraulic support cylinders, a plurality of support plates, a plurality of second hydraulic support cylinders shorter than the first hydraulic support cylinders, a slide plate, and a plurality of horizontal hydraulic cylinders. The lower cutting table includes a first front end including a first mounting groove, and a second mounting groove, and an inner plate. The bottom wall of the second mounting groove includes a plurality of first bolt holes and a plurality of first recesses. The inner plate is embedded in the second mounting groove through a plurality of bolts passing through the plurality of first bolt holes. The inner plate includes a plurality of second bolt holes and a plurality of second recesses. The plurality of support plates lean against the inner plate.
