A machine configured to form at least one whip from a length of cable according to some embodiments of the disclosure includes an input and an output defining a cable travel space being therebetween; a clamping assembly including a pad, and a first driving assembly configured to move the pad into the cable travel space and out of the cable travel space; and a cutting assembly including a cutting tool having at least one cutting edge, and a second driving assembly configured to move the cutting tool into the cable travel space and out of the cable travel space. In some embodiments, the machine further includes a saw assembly including a notching saw having a cutting edge configured to intersect the cable travel space, and a third driving assembly configured to drive the notching saw.

A control device according to some embodiments of the disclosure includes one or more motors directed by the control device to form whip(s) from a length of a cable by causing the cutting of the cable in accordance with specifications based at least in part on whip information. An interface communicates the whip information between the control device and a user device.

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 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.

A tool head includes a first frame having first and second arms extending from a base to a distal end. The tool head may also include a first blade in the frame between the first and second arms. The first blade is movable from the base toward the distal end. The tool head includes a second frame hingedly coupled to the first arm. The second frame may include a second blade. The second frame is configured to rotate between a closed-frame position and an open-frame position. The tool head includes a trip lever hingedly coupled to the first arm and configured to rotate between an open-lever position and a closed-lever position.

A cutting device for cutting a number of structural steels in series is disclosed. The cutting device may include a cutting mechanism coupled to an actuating mechanism, both mounted on a support frame. The cutting mechanism may include a stationary cutting member having a plurality of openings and a movable cutting member mounted in side-by-side abutment with the stationary cutting member. Each lateral opening on the stationary cutting member is aligned with the corresponding opening on the movable cutting member, thereby forming a single extended opening, which is capable of receiving a workpiece therein. The movable cutting member is movable relative to the stationary cutting member from a first position to a second position. As the movable cutting member moves, it moves the aligned openings of the individual cutting members out of alignment one after another thereby shearing the workpieces in the process.
