Description
Technical Field
The invention relates to a power wire manufacturing mechanism, in particular to a wire single-wire drawing machine.
Background
Electric power is an important energy source essential for national economy development, and the demand for electric power is greatly increased along with the continuous high-speed development of national economy in China. Transmission lines are an important component in the supply of electricity, being a tie that delivers the electrical energy of a power plant to thousands of households. By 2020, 9.68 km of transmission lines are built in China, and 3.2 km of transmission lines are newly added in China to 2035. The conducting wire is a core component of the power transmission line, the mechanical strength of the conducting wire is related to the safety of the power transmission line, the conductivity of the conducting wire is directly related to the loss of electric energy, and the conducting wire with high strength and good conductivity is the development direction of the safety and low consumption of the power transmission line.
The transmission conductor is mainly manufactured by stranded wires of the single conductor wires according to a specific structural form, so that the physical properties of the single conductor wires directly determine the overall mechanical and electrical properties of the transmission conductor. The production of the single wire of the wire is a complex thermodynamic coupling process, relates to a plurality of subjects such as physics, materials, mechanics, heat and the like, is difficult to accurately control each key technical parameter (plastic deformation amount, deformation temperature, deformation rate and the like) in the production process of the single wire of the wire, and particularly applies and regulates the large plastic deformation of the single wire of the wire, and if the accurate regulation and control of the parameters are realized, the research and development of a novel wire can be guided, and then the high-strength and high-conductivity power transmission wire is prepared.
The constraint extrusion in the field of machining and manufacturing is a heavy plastic deformation technology integrating large deformation, high strain rate and high temperature, and the plastic deformation, the deformation rate and the deformation temperature can be accurately controlled by adjusting and controlling the extrusion thickness ratio, the extrusion speed and the external environment temperature.
The fourth chapter of "overhead wire manufacturing process and equipment" by Wan Ji et al, "overhead wire application technology," discloses a wire single wire manufacturing technology commonly used in the industry as shown in FIG. 1 (Wan Ji et al, beijing, chinese electric Press, 2015.6). The key area of the single wire of the drawn wire is divided into four sections, namely an inlet section, a working section, a sizing section and an outlet section. The initial single wire enters from the inlet area and gradually enters the working area, and plastic deformation is carried out in the working area; after the initial single wire passes through the working area, the diameter of the single wire reaches the set diameter of the single wire in the sizing area, and finally, the single wire with the set diameter is formed from the outlet area. Because the single wire diameter can only be reduced by about 5% in one drawing process, the single wire diameter can be changed from d by a multi-pass drawing process 0 Reduced to the desired diameter d n 。
The existing single wire preparation technique shown in fig. 1 has the following technical disadvantages: 1) The initial single wire diameter can be reduced to the required specific diameter only by a multi-pass drawing process, and the single wire preparation process is complex; 2) The temperature field and the speed field of the single wire manufacturing process of the lead cannot be effectively and accurately controlled. The main reason of the technical disadvantage 1) is that the large drawing plastic deformation amount easily causes the breakage of the single wire in the drawing process, and particularly when the single wire diameter is reduced by more than 30% in one drawing process, the breakage of the single wire is extremely easy to occur. Therefore, in one drawing process, the plastic deformation amount is small, that is, the diameter reduction amount is as small as 5% as possible. This determines that the fabrication technique of fig. 1 requires a multi-pass drawing process, and therefore, the single wire fabrication process is complex. The main reason of the technical defect 2) is that the single-wire sample moves among a plurality of drawing dies in the multi-pass drawing process, and the single-wire sample is difficult to be clamped for a plurality of times, so that the single and stable preparation environment is very difficult to be ensured. After one-time drawing forming is finished, a single wire sample is required to be taken out, and then the taken single wire sample is moved to a next-time drawing device to serve as an initial sample of the next-time drawing forming, so that the single wire sample is inevitably caused to undergo the processes of cooling in air and zero drawing speed by multi-time reciprocating movement and clamping of the single wire sample, the temperature and drawing speed in the single wire preparation process cannot be maintained at a specific value at any moment, and therefore, the temperature field and the speed field in the wire single wire preparation process cannot be accurately controlled.
CN 103335907A chinese patent application discloses a quasi-static constraint cutting experimental device based on loading technology of material testing machine, wherein the technical principle of constraint extrusion cutting deformation field control is introduced in detail. Fig. 2 shows an experiment in which a cutting specimen is subjected to constraint cutting based on a loading technique of a material testing machine. As shown in fig. 2, after the left and right spatial positions between the limiting block and the cutter are determined, namely, the cutting thickness is kept unchanged; when the adjusting pad is thinner, the upper and lower space positions between the limiting block and the cutter are smaller, namely the chip thickness is smaller, and the deformation field of the cutting process is larger. Therefore, the cutting of the controllable deformation field of the cutting sample is realized by adjusting the relative positions among the limiting block, the limiting pin, the adjusting gasket and the cutting tool.
The quasi-static constraint cutting experimental device based on the loading technology of the material testing machine shown in fig. 2 of the prior art has the following disadvantages: 1) The constraint cutting travel is short, about 20mm, and a wire single line with the length of hundreds of meters cannot be prepared; 2) The chip moves in the limited space, and when the adjusting pad is thin, the chip is very easy to block the space and stop moving, so that the whole constraint cutting action is stopped. The main reason of the technical defect 1) is that the invention is positioned in experimental study of scientific mechanism, and based on the loading technology of the material mechanical testing machine, the loading stroke of the material mechanical testing machine is small, so that the technical scheme cannot be applied to practical engineering of single wire preparation of a wire. The main reason of the technical disadvantage 2) is that the existence of the limiting block limits the movement space of the chip, when the adjusting pad is thinner, the larger the extrusion force between the chip and the limiting block as well as between the chip and the cutting tool is, the larger the resistance of the chip movement is caused, so that the movement behavior of the chip is stopped, and the preparation of a single wire of the lead is also not facilitated.

In one embodiment of the invention, when the single wire of the wire is drawn:
as shown in fig. 3, after the wire is input through the rotation of the clockwise rotating mechanism paying-off wheel 1 in the upper left corner shown in fig. 3, the wire is sequentially subjected to wire input guiding wheel set 2, wire radial constraint mechanism 10 and wire output guiding wheel 4 under the drawing of the anticlockwise rotating wire output mechanism coiling wheel 5 in the lower right corner shown in fig. 3, and then is output through the anticlockwise rotating coiling wheel 5, so that the drawn wire is obtained.
