An in-line portable, hand held hydraulic cutting tool having a handle assembly and a working head assembly is provided. The handle assembly has a tool frame portion and a neck portion. The working head assembly has a pair of jaw members joined so that they are movable relative to each other and held in place by a locking pin. Each jaw member has a cutting blade secured to or directly formed into the jaw member. A stabilizer can be secured to or directly formed into one or both jaw members. The one or more stabilizers are aligned with a respective cutting blade such that during a cutting operation at least an edge of the stabilizer engages an object being cut to limit rotation of the object during the cutting operation.

A cutting head for a hydraulic power tool includes a first jaw that includes a first ear configured with a slot for receiving a corresponding ear. The second jaw includes a second ear with a third ear bore that aligns in between a first ear bore and to a second ear bore of the first ear when the second ear is coupled in the slot of the first ear. The cutting head further includes a spring-biased flange coupled to a blade mounted to the first jaw and a retained coupled at a fixed position to a blade mounted to the second jaw. The retainer is configured to receive the flange during a cutting action such that the flange prevents the blades from shifting out of alignment during the cutting action.

A can cutting device that has a main body and a can support assembly coupled to the main body. The can support assembly has a shaft that extends along a longitudinal shaft axis, an eccentrically mounted mandrel that extends along a longitudinal mandrel axis parallel to the longitudinal shaft axis, and a cutter coupled to the main body having a cutting surface. The can is positionable in a mounted position such that the can is rotatable about a can axis of rotation, the cutting surface is positional to contact the portion of the can body supported by the mandrel at the cutting location, and when the cutting surface is in contact with the portion of the can body supported by the mandrel at the cutting location and the can is rotated about the can axis of rotation, the cutter cuts the portion of the can body at the cutting location.

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 θ.sub.1 of the first cutting part and a front end angle θ.sub.2 of the second cutting part are each 100 or more and 1200 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.

A method is for cutting a tubular structure in the petrochemical industry, using a cutting tool having a non-rotatable cutting element and a reaction member opposite to the non-rotatable cutting element. The cutting tool is further configured for carrying out a translational cutting movement through the tubular structure. The method comprises: a) positioning the cutting tool in a first position exterior to the tubular structure; b) squeezing the tubular structure at the first position by activating a partial translational cutting movement of the non-rotatable cutting element to obtain a dented region in the tubular structure; c) positioning the cutting tool in a second position exterior to the tubular structure, wherein the second position is displaced over a predefined distance compared to the first position, and d) cutting the tubular structure at the second position (P2) by activating a full translational cutting movement of the non-rotatable cutting element through the tubular structure.

The present invention has as its technical problem to provide a punching method able to stably secure a stretch-flangeability equal to or greater than the case of using a punch having a flat blade at its bottom surface. The punching method of the present invention is a method of punching a metal sheet using a punching and shearing device provided with a punch having an upper blade having a horizontal part with respect to the cutting line in part and having parts other than the horizontal part comprised of inclined parts and a die having a lower blade wherein the upper blade used for the punching process has a shape where the inclined parts first contact the metal sheet at the time of a punching process.

A blade is configured for use in cutting metal studs, the blade including a cutting edge, the cutting edge configured to engage a metal stud such that the metal stud and debris from a cut of the metal stud are pushed in different directions. Cutting machines including the blade are also disclosed, as methods of cutting metal studs using the blade.

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 device with the capability of cutting hard materials, such as steels, stainless steels and other similar and exotic alloys. The cutting device includes a cutter head having a central aperture and a stationary body having a channel extending therethrough. The stationary body extends through the central aperture of the cutter head. The cutter head is rotatable between a first configuration and a second configuration relative to the stationary body. The cutting device also includes first and second substantially parallel blades fixed to the stationary body. In the first configuration, the first blade is a first distance from the second blade. In the second configuration, the first blade is a second distance from the second blade. The cutting assembly is connected to a drive mechanism with a driver and an actuator. The actuator connects the cutter head to the driver. Engagement of the driver rotates the actuator, which rotates the cutter head.

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.
