A portable cutting line may include a frame and a lazy susan. The portable cutting line may also include a cutting line main table, the cutting line main table operatively connected to the lazy susan and one or more tubs, the tubs operatively connected to the cutting line main table. The lazy susan, the cutting line main table, and the one or more tubs may be positioned within the frame when in transport position.

The untethered remote wire cutting system includes a control unit with a unit housing carrying a user input interface coupled to control circuitry, a unit battery, an associated control transceiver, and a unit antenna, and configured to transmit wireless cutting control signals. One or more wire cutting devices each include a device housing carrying device circuitry, a device battery, an associated device transceiver, and a device antenna, and configured to receive wireless cutting control signals from the control unit. The wire cutting device includes a blade guide, having wire retaining slots, and coupled to the device housing. Also, a blade is configured for linear movement within the blade guide, and a linear actuator is carried within the device housing, coupled to the blade, and controlled by the device circuitry to move the blade linearly within the blade guide and passed the wire retaining slots.

Disclosed is a method for manufacturing a spring for a spring brake, including a shaping and cutting step f) including the following sub-steps: —f1) shaping a raw wire into a coil with a plurality of raw turns, the raw wire having: raw portions that extend from the end of the raw wire over at least one raw turn, and an intermediate portion between the raw portions, —f2) separating the first raw portion and the second raw portion of the raw wire by cutting, after implementing sub-step f1), and —f3) shaping a first tab (5), at a first end of the intermediate portion, after sub-step f1), and —f4) shaping a second tab (7), at a second end of the intermediate portion opposite the first end, after sub-step f1).

A multistage press for the bulk deformation of a piece of wire includes a wire feed with associated apparatus for cutting to length, and a transfer device—having grippers—for receiving a piece of wire that has been cut to length and transferring the latter to subsequent forming stages, there being arranged, on that side of the cutting-to-length apparatus opposite from the wire feed, a device for partially heating a length of wire. A method produces a formed part with a multistage press of this type.

A coiling machine includes feed rollers for moving a wire, a wire guide, a first forming roller, a second forming roller, a pitch tool, a cutting mechanism, and a support mechanism for supporting the wire. The cutting mechanism includes a cutting rotor. The wire coming out of the wire guide is formed into a helical shape by the first forming roller, the second forming roller and the pitch tool. After one coil spring of a predetermined length is formed, the wire is cut by moving the cutting rotor in the radial direction of the wire. The cutting rotor cuts the wire supported by the support mechanism in the radial direction of the wire between the second forming roller and the pitch tool.

A table shear may include a clamp and a shearing mechanism, the shearing mechanism supported by the clamp. The shearing mechanism may include a fixed lower shear blade, a lower shear blade backup plate supporting the fixed lower shear blade, a moveable upper shear blade and a shear compression cylinder. The shear compression cylinder abuts the movable upper shear blade.

The invention relates to a method for burr-free cutting-off of a wire, an apparatus for burr-free cutting-off of a wire, a wire piece and a hairpin.
