The conductor stranding is that a plurality of single wires with the same diameter or different diameters are stranded together according to a certain direction and a certain rule to form an integral stranded wire core. According to the twisting form, the wire twisting is subdivided into regular twisting and irregular twisting; the regular stranding means that the single wires are stranded around the stranded wire central layer single wire as an axis in a layered and orderly manner, the relative positions of the single wires are fixed, and the twisting directions of adjacent layers are opposite. The central layer can be composed of one or more single wires, but usually one, the second layer is six, and then each layer is six more than the previous layer; for example: 1+6, 1+6+12+18, etc. In the existing normal twisting die, all single wires are directly converged at one end of a die stranded wire hole and then penetrate into the stranded wire hole, so that all the single wires are in the same wire inlet channel for a long time before being twisted.

Detailed Description
For ease of understanding, the specific structure and operation of the present invention is further described herein with reference to FIGS. 1-3:
in the regular twisting process, due to the shaking of the wire body during the advancing process, the position of the central layer single wire a and the position of the outer layer single wire b are disordered sometimes, so that the staggering and poor twisting are caused, the sudden change of the twisting outer diameter is further caused, and the extrusion molding breakdown is easily caused; this occurs very frequently when the filaments are thick and are produced using beamline equipment. In view of the above, the present invention employs the cooperation of the daughter mold 20 and the mother mold 30 as shown in FIGS. 1-3. In one aspect, the present invention uses a mold having a special shape, i.e., a tube cavity having a two-step stepped hole and an outer wall of a two-step stepped shaft, as the sub-mold 20, and fixes it to the second mold base 40. The second die holder 40 is fixed to the first die holder 10 by a screw. Meanwhile, the master mold 30 is fixed to the first mold base 10 in a conventional mold size. On the other hand, the sub-mold 20, the main mold 30 and the corresponding mold bases are concentric; and then the outer ring 43 of the second die holder 40 is matched with the thread of the through cavity 11 of the first die holder 10, so that the function of adjusting the distance between the second die holder 40 and the first die holder 10 is realized, and the purpose of controlling the distance between the secondary die 20 and the female die 30 on line is further realized. During actual production, the central layer single wire a passes through the central positioning hole 21 of the sub die 20 and then enters the stranded wire hole 31 of the female die 30, while the outer layer single wire b enters the passing cavity 11 from the empty position of the sub die 20 and the second die holder 40 and then is converged at the stranded wire hole 31 of the female die 30, and finally the central layer single wire a and the outer layer single wire b are jointly subjected to normal stranding operation at the female die 30. The strand hole 31 may employ a neck-shaped hole pattern as shown in fig. 1 so that the individual wires can smoothly enter and be twisted.
In addition, since copper powder falls off in the production process, in order to avoid copper powder accumulation between the sub die 20 and the female die 30, the copper powder suction assembly is designed by opening a hole on the first die holder 10. During the specific use, the copper powder absorption and collection assembly can be a pure negative pressure absorption hole, so that the copper powder is forcibly absorbed by using external negative pressure equipment to realize the collection effect of the copper powder. Of course, it is also possible to adopt the structure shown in fig. 1 and 3, that is, the bushing 60 is fixed and the annular channel 61 is formed by the cooperation of the bushing 60 and the radial hole, and then the purpose of collecting the copper powder on line is achieved by the gas drainage hole 62 existing at the bushing 60 and the compressed air inlet hole 12 preset at the first die holder 10. After the compressed air enters the compressed air inlet hole 12, the compressed air is ejected from the gas drainage hole 62 through the annular hole 61, so that a negative pressure environment is formed in the tube cavity of the bushing 60, namely at the negative pressure suction hole, and the copper powder originally located in the through cavity 11 is sucked out to the external copper powder collecting device 50 such as a collecting box due to the negative pressure effect of the negative pressure suction hole. Therefore, the copper powder suction and collection assembly can avoid the problem of line silting caused by the accumulation of copper powder at the female die 30, achieves the functions of online recovery and reuse of the copper powder, improves the environment, generates certain economic benefit and has extremely remarkable effect.
