The steel cord cut end preparation device comprises a set of clamps for clamping a length of steel cord, a rotating driving unit for driving the clamped length of steel cord to be over-twisted and at least one cutter for cutting the steel cord at the over-twisted portion to make a cut end of steel cord, the steel cord cut end preparation device further comprises a heating unit for heating the clamped length of steel cord and a controller for controlling the heating unit and the rotating driving unit, so that the clamped length of steel cord is heated during, before or after it is over-twisted. By using this device, the steel cord welding success ratio is increased.

A straightening apparatus for straightening cables includes a first roller group having several rollers and a second roller group having several rollers opposite the first roller group. The cable alternates in a transport direction between the rollers of the first roller group and the rollers of the second roller group. The straightening apparatus further includes an infeed device with which the first roller group can be displaced in a closing direction against the second roller group. In order to secure the position of the first roller group displaced in the closing direction by the infeed device, the straightening apparatus includes a backstop which blocks a backward movement of the first roller group against the closing direction. The backstop has a clamping roller which is received in a wedge gap.

A method of producing shaped parts includes drawing wire from a wire stock and feeding the wire to a processing machine; straightening the wire in the wire processing machine; and separating shaped parts of a predefinable wire length from the straightened wire, wherein, to separate a shaped part from the fed wire, at a separating position provided for separation, the wire is first notched in at least one notching operation from two opposite sides by notching tools such that a tapered wire cross section remains between opposing notches at the separating position, and in a dividing operation, the notched wire is separated at the separating position in a region of the tapered wire cross section by engagement of two dividing tools on opposite sides of the wire and their synchronous feed in opposite feed directions perpendicularly to the wire axis until the wire material is severed at the separating position.

Disclosed is a device for repairing deep-water cage nets. The device includes an open-frame underwater robot and a repairing mechanism of deep-water cage nets, where the repairing mechanism of deep-water cage nets includes a hole penetrating mechanism, a wire feeding mechanism, a rotary knotting mechanism, a steel wire cutting mechanism and steel wire clamping mechanisms. The hole penetrating mechanism comprises mechanical claws and a control box for controlling the mechanical claws. The wire feeding mechanism and the steel wire cutting mechanism are both fixedly arranged in the control box, and the steel wire clamping mechanisms and the rotary knotting mechanism are both arranged between two mechanical claws. The open-frame underwater robot is detachably connected with the repairing mechanism of deep-water cage nets through a connecting shaft.

A binding machine includes a wire feeding unit, a curl forming unit, a cutting unit, and a binding unit. The binding unit includes a locking member that includes a first hook and a second hook and that locks the wire by moving the first hook toward the second hook. The locking member includes a locking part that locks the wire in a state in which the first hook has been moved toward the second hook, and an unlocking part that makes it possible for the first hook to be movable away from the second hook with such an amount of movement that the locked wire does not come off between the first hook and the second hook.

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.

A method of manufacturing blind rivets is revealed. First cutting a steel wire rod to get a rod with required length and forming a head portion at one end of the rod. Then performing threading on an outer surface of the rod to form outer threads and carrying out heat treatment including quenching and tempering at 380° C.±50° C. to get a threaded rod. Next cutting a steel wire rod according to a length required to get a tube and forming a through hole axially penetrating the tube and corresponding to the threaded rod. Then forming a mounting portion at an outer edge of one end of the tube, carrying out optical heat treatment at 1100° C.±100° C., and performing electroplating to get an outer tube. Lastly the threaded rod is inserted into the through hole of the outer tube and the assembly is completed.
