摘要:
A piercing tip for a demolition shear, the piercing tip including a blade-side sidewall and a guide-side sidewall, a front wall, and a bottom wall. An intersection of a front outer wear surface of the front wall and a bottom wear surface of the bottom wall defines a front piercing edge. An intersection of a planar outer wear surface of the blade-side sidewall and the bottom wear surface of the bottom wall defines a shearing edge. A blade set may include the piercing tip and at least one shear blade. The piercing tip and at least one shear blade may be mounted to the blade-side of an upper jaw of the demolition shear.

A cutting head for a power tool. The cutting head includes a first jaw having a first blade mounting surface and a second jaw having a second blade mounting surface. The second jaw is rotatably coupled to the first jaw. The cutting head also includes a first blade removably coupled to the first blade mounting surface of the first jaw and a second blade removably coupled to the second blade mounting surface of the second jaw. A first cutting edge of the first blade is substantially co-planar with a second cutting edge of the second blade. During a cutting action, the first jaw and the second jaw rotate with respect to one another to bring the first cutting edge closer to the second cutting edge.

A shear blade is for a portable hydraulic cutting device having a blade body. The blade body has assembly and cutting regions, with a cutting edge in the cutting region. A contact surface is on one side of the cutting edge for an additional shear blade. An outer surface on the other side of the cutting edge acts on the object to be cut. A first surface portion of the outer surface extends away from the cutting edge along an orthogonal, which meets the contact surface at the cutting edge, or at an acute angle α relative to the orthogonal. A second surface portion connects to the first surface portion at an acute angle β to the orthogonal. A third surface portion connects to the second surface portion at an acute angle γ to the orthogonal. Angle α is smaller than angle β, which is smaller than angle γ.

A demolition shear and a piercing tip insert and nose configuration for a demolition shear which resists nose wear and resists retract forces exerted on the piercing tip insert in jamming situations and in the event of snagging of the piercing tip insert. The piercing tip insert includes first and second piercing tip halves, each half having an outer planar sidewall, a curved front wall extending laterally inward, and a bottom leg extending laterally inward defining a shearing edge and a piercing edge.

The invention concerns a cutting device (1) for reducing the width of a ready-made roller blind blank (28) comprising a roller tube onto which a fabric has been wound. The cutting device (1) comprises a mandrel (13), which is adapted to be inserted into and hold an end to be cut of the roller tube, and a knife arrangement, which is adapted to circumferentially cut first the fabric wound on the roller tube and then the roller tube on the mandrel (13) such that the width of the ready-made roller blind blank (28) is reduced. The invention also concerns a ready-made roller blind blank (28), which comprises a roller tube, onto which a fabric has been wound and which is adapted to be cut by means of a cutting device (1) according to the invention. For this the roller blind blank (28) comprises a disposable wrapping, which bears a visible measurement scale along at least one end portion of the roller blind blank (28).

A one piece three-sided hardened steel boot tip for a distal end upper jaw tang of a heavy duty demolition shear having a upper movable shear jaw with a shear tip or tang. The boot tip has a front wall seated on the tang front edge and a right sidewall. A bottom wall of the boot tip is seated on the tang bottom seat forming a shear punching edge between the front wall and the bottom wall. A sidewall is connected to the tang bottom and front walls with a shearing edge between the side and bottom walls. A side plate with an indexing hub is seated on the guide side tang face, the top seat and the rear seat.

The present disclosure describes various embodiments, as well as features and aspects thereof, of a system, for a shear, of fully indexable cutting portions comprises at least one blade and a plurality of substantially identical indexable cutting portions. The at least one blade is configured to mechanically receive a plurality of indexable cutting portions. The plurality of substantially identical indexable cutting portions are arranged on the at least one blade to form a composite angled cutting edge. The composite angled cutting edge comprises at least one angle. Each indexable cutting portion comprises a coupling portion and eight edges. The coupling portion of each indexable cutting portion is configured to mechanically engage the indexable cutting portion to the at least one blade.
