A method for adjusting a roll segment of a strand guide of a slab-casting installation against a strand, wherein the roll segment has an upper and a lower roll support that each have an adjusting element for adjusting the two roll supports relative to each other. The method includes individual control of the individual adjusting elements, wherein the actual profile of the strand, including the heights of the right and left lateral edges of the strand, is detected and compared with a set profile that includes a predetermined set height, which is the same for the right and left lateral edges, and the individual adjusting elements of the roll segment are individually controlled based on the control deviation that results from the comparison so that the actual profile is adapted to the set profile, including equalization of the heights of the right and left lateral edges of the strand.

The invention discloses a cable stranding machine. The cable stranding machine comprises at least one wire-releasing and wire-stranding apparatus and a rolling-up apparatus, wherein when the number of the wire-releasing and wire-stranding apparatus is one, the wire-releasing and wire-stranding apparatus comprises a rotary wire-releasing apparatus A, a wire-dividing apparatus A and a wire-stranding apparatus A; when a wire on a wire-releasing reel on the rotary wire-releasing apparatus A passes through the rotary wire-releasing apparatus A, the wire-dividing apparatus A and the wire-stranding apparatus A, the wire is stranded into a cable core; the cable core is connected with the rolling-up apparatus; a driving motor A supplies the driving power to the rolling-up apparatus; and the driving motor A drives the rolling-up apparatus to roll up the stranded wire of the wire-releasing reel. According to the structure of the cable stranding machine, the wires are stranded or stranded in a multilayered manner to form the cable core, so that cables of different specifications can be produced, and the applicability of the equipment is improved.

The invention discloses a pitch control mechanism of a stranding machine. The pitch control mechanism comprises a bobbin, a left disc and a right disc. A right pinch roller, an A group of belt pulley and a B group of belt pulley are arranged on the right disc; a left pinch roller, a C group of belt pulley and a D group of belt pulley are arranged on the left disc. The pitch control mechanism has the advantages that the pitch control mechanism is ingenious and reasonable in design, and belt-pulley transmission is substituted for conventional gear transmission, so that structure is simplified effectively, and simplicity and convenience in operation are achieved; when stranding pitch adjustment is needed, the belt pulleys, with the corresponding tooth numbers, in the A, B, C and D groups of belt pulleys are selected according to stranding pitches as needed, and then left and right belts are tensioned by the left pinch roller and the right pinch roller to complete adjustment, so that adjustment speed is high, flexible matching is achieved, stranding pitch adjustment range is wide, time and labor are saved, a large amount of time and manpower are saved effectively, working efficiency is high, the whole production cycle is shortened, stranding quality is improved, and production cost is reduced; in addition, the pitch control mechanism is simple and compact in overall structure, easy to produce, low in cost, high in working stability and beneficial to wide popularization and application, and has few used parts.

A device for improving the roundness of conductor stranding, including a twist bow, on which several magnetic eyes are arranged; the radial distance between the magnetic eyes at the two ends of the twist bow and the twist bow is the largest, and in the middle, the magnetic eyes and the twist bow The radial distance of the bow is gradually reduced, and the distance between the magnetic eyes is gradually reduced. In the device of the present invention, the hollow state of the copper wire is kept very well, and the quality of the twisted wire is the highest.
