摘要： A motor-operated shears which includes two blades that can move towards each other to perform a shearing movement is provided. In order to advantageously improve functional safety, towards the end of the movement, the blades are acted upon in a direction running transversely to the movement so as to keep the blades at a distance from one another in said direction.

摘要： The invention discloses an automatic cooling and steel cutting device, which includes a casing, wherein the right end of the casing is provided with a conveying cavity, a connecting cavity and a driving cavity, the conveying cavity is provided with a conveying mechanism for pushing steel for cutting and the opening is upward, the connecting cavity is provided with a lifting mechanism for lifting the cutting part, the lower side of the connecting cavity is provided with a cutting mechanism for cutting steel. The device can cut off the steel evenly by itself when it is in use. During the cutting process, it will automatically spray water to cool down the steel and the cutter, so as to reduce the damage. After each section is cut, the cutter will automatically lift up to prepare the next section of steel cutting of wood.

摘要： A pair of single-blade-double-edged steel wire rope shears, includes: a first cutting member and a second cutting member pivotally connected to each other. The first cutting member includes a first grip and a first blade, the first blade includes a first lateral cutting edge and a first bottom cutting edge; the second cutting member includes a second grip and a second blade, the second blade includes a second lateral cutting edge and a second bottom cutting edge; when the first and second grips pivot toward each other, the first and second lateral cutting edges cut a to-be-cut object inserted therebeween, meanwhile, the first and second bottom cutting edges also cut the to-be-cut object, so as to form at least three cutting points on the to-be-cut object, and as a result, the pair of single-blade-double-edged steel wire rope shears can improve cutting efficiency.

摘要： A workpiece cutting method basically includes providing a workpiece proximate to a first blade including a first cutting edge. The method further comprises moving a second blade including a second cutting edge in contact with the first blade such that the first and second cutting edges of the first and second blades cooperatively engage to cut the workpiece while maintaining the first and second cutting edges parallel to each other.

摘要： A rotary cutting device comprising an anvil and roll having at least one knife affixed thereon, the roll being rotatably mounted to the machine by bearings disposed on opposing ends of the roll and supported by bearing mounts connected to the machine frame. A thermal isolating mounting arrangement orients the bearing mounts so that thermal growth occurs along an axis generally perpendicular to a plane in which the knife and anvil interface. A thermal isolator may also be disposed between the bearing mounts and the machine frame to further inhibit heat transfer into the frame and the resultant effect on knife position.

摘要： First and second dies can be coupled to a pair of arms on a threaded rod cutting machine. The first die has a body with a front face, a rear face, a side face extending between the front face and the rear face, and a first threaded recess in the first side face and configured to receive a threaded rod to be cut. Crests and troughs of the first thread are aligned with troughs and crests of the threaded rod when the first die engages the rod. The second die has a body with a front face, a side face extending between the front face and the rear face, and a second threaded recess in the side face and configured to receive the threaded rod. Crests and troughs of the second thread are axially offset from troughs and crests of the threaded rod when the second die engages the rod.

摘要： A one piece four-sided hardened steel boot tip is mounted to a distal end upper jaw tang of a heavy duty demolition. The boot tip has a front wall seated on the tang front edge and a right side wall seated on the shear side tang face and radiused or curved rear seat. A top wall has a radiused inside top wall that sits on the radiused tang top seat. A bottom wall of the boot tip has a radiused inside top wall that is seated on the tang radiused bottom seat forming a shear punching edge between the front wall and the bottom wall. The boot tip has a shear side shearing edge that is between the sidewall and the bottom wall of the boot tip. An access or side plate is seated on the guide side tang face, a portion of the radiused boot bottom wall and the radiused rear seat. The side plate is flush with the bottom and front walls. The boot tip right side and access plate have matching apertures therethrough and alignable with the tang apertures to secure the boot and access plate to the tang for encapsulating protection thereof from the lower jaw shear side, the guide side and the tie plate as the upper jaw moves into and out of the recess therebetween. One or more shims may be provided that are insertable inside the boot against the tang faces and clampable thereto after the faces have become worn or otherwise requires adjustment for maximum clamping force.

摘要： The present invention provides a method and apparatus of reducing current requirements by increasing resistance of the blade structure by reducing the cross sectional area of at least one section of the blade so that the electrical current requirements for heating of the blade to cutting temperature are reduced wherein the power supply and substantially entire unit may be mounted within a hand held unit. Methods of shaping blades to perform various heat distributions for specialty blades for custom cutting are disclosed. Further, an improved blade mounting structure is provided which includes structure for maintaining the legs of the blade parallel to the direction of cut and provides for easy insertion of new blades by maintaining a slotted blade cradle stable and in alignment with the blades and a clamp member away from the blade when the clamp mounting structure is loosened.
