Abstract
The present utility model relates to a conductor twisting and drawing die cooled by circulating alcohol. The die comprises a die shell and a die core, and is characterized in that a cooling liquid circulating cavity and a die core installing hole are arranged on the die shell, a liquid-entering joint and a liquid-returning joint which are communicated with the cooling liquid circulating cavity are arranged on the die shell along the radial direction, the die core is arranged inside the die core installing hole and connected with the die shell through screw threads, and sealing rings are uniformly arranged on the contact surface of the module core and the die shell. By adopting the die, the phenomenon that irregular and nonuniform black spots are generated on the surface of a conductor can be avoided; the cable quality can be enhanced, production costs can be reduced, service life of the die can be prolonged, and the die is simple in structure, convenient to manufacture and good in cooling effects.
Description
Technical field
The utility model belongs to electric wire manufacturing technology field, particularly relates to a kind of stranded drawing mould of conductor that utilizes the cooling of circulation alcohol.
Background technology
At present, known drawing mould is that shell is a solid, when conductor and mould friction generates high temperature, drips to transformer oil or industrial alcohol on the conductor of mould leading portion and cools off.This type of cooling has following some deficiency: 1. transformer oil has adhesiveness and contains impurity, and industrial alcohol contains moisture, and under the condition of high temperature, transformer oil and impurity, moisture make conductive surface produce irregular inhomogeneous blackspot film phenomenon easily; 2. in extrusion process, remaining oil, moisture produce gas and cause the insulation protrusion, influence cable quality; 3. transformer oil or industrial alcohol can not reclaim, and can only disposablely use, and have increased production cost virtually; 4. even with transformer oil or industrial alcohol inhomogeneous cooling, cooling that can only locality causes die surface injured easily.The employing water-cooled drawing mould that also has only a few, when conductor and mould friction generates high temperature, water is in the mould inside cooling that circulates.This type of cooling has following some deficiency: 1. the specific heat of water appearance is bigger, is that intensification or cooling are all slow, so cooling effect is not good especially; 2. mould inside when mould is idle, makes mould inside get rusty through after the boiler water circulation easily, thus the useful life of reducing mould greatly.
Summary of the invention
The utility model provides a kind of trouble and worry that can solve the conductor blackening for solving the technical problem that exists in the known technology; Improve the quality of products; Reduce production costs, prolong die life, reach the stranded drawing mould of conductor of the utilization circulation alcohol cooling of fine cooling effect.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of stranded drawing mould of conductor that utilizes the cooling of circulation alcohol; Comprise mold shell and core rod; It is characterized in that: said mold shell is provided with liquid circulation chamber, core rod installing hole, and radially mold shell is provided with the liquid inlet joint and time liquid joint that is communicated with the liquid circulation chamber, and said core rod is installed in the core rod installing hole; And be connected with mold shell through screw thread, be equipped with sealing ring between said core rod and the mold shell contact-making surface.
Advantage and the good effect that the utlity model has are: the utility model provides a kind of stranded drawing mould of conductor that utilizes the cooling of circulation alcohol, and this mould can not only reach good cooling effect, and can solve the technical problem that prior art exists:
1. solved transformer oil and had adhesiveness and contain impurity, industrial alcohol contains moisture, and under the condition of high temperature, transformer oil and impurity, moisture make conductive surface produce the phenomenon of irregular inhomogeneous blackspot film easily;
2. solved in extrusion process, remaining oil, moisture produce gas and cause the insulation protrusion, influence the problem of cable quality;
3. having solved transformer oil or industrial alcohol can not reclaim, and can only disposablely use, and has increased the problem of production cost virtually;
4. solved with transformer oil or industrial alcohol inhomogeneous cooling evenly, cooling that can only locality causes the injured problem of die surface easily;
5. solved specific heat of water hold bigger, be heat up or cooling all slow, the bad problem of the cooling effect that causes;
6. solved mould inside through after the boiler water circulation, when mould is idle, mould inside has been got rusty, thereby reduce the problem of die life greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the utility model fundamental diagram.
Among the figure: 1, mold shell; 1-1, liquid circulation chamber; 1-2, core rod installing hole; 1-3, screw thread; 2, core rod; 3, liquid inlet joint; 4, return the liquid joint; 5, sealing ring; 6, water pump; 7, water tank; 8, water inlet pipe; 9, return pipe.
Embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1; A kind of stranded drawing mould of conductor that utilizes the cooling of circulation alcohol comprises mold shell 1 and core rod 2, and said mold shell 1 is provided with liquid circulation chamber 1-1, core rod installing hole 1-2; Radially mold shell 1 is provided with the liquid inlet joint 3 and time liquid joint 4 that is communicated with liquid circulation chamber 1-1; Said core rod 2 is installed in the core rod installing hole 1-2, and is connected with mold shell 1 through screw thread 1-3, is equipped with sealing ring 5 between said core rod 2 and mold shell 1 contact-making surface.
See also Fig. 2, water pump 6 immerses in the spirituous water tank 7, and the water inlet pipe 8 that comes out from water pump is connected with liquid inlet joint 3, and return pipe 9 is connected with water tank 7 with time liquid joint 4 respectively.When pump working, alcohol will flow into liquid circulation chamber 1-1 along water inlet pipe 2 and evenly cool off, and the alcohol that has heat after the cooling flows into water tank 7 along return pipe 9, forms a cooling circuit like this.
The utility model can improve cable quality in sum, reduces production costs, and prolongs die life, and the utility model also has advantages such as simple in structure, easily manufactured, good cooling results in addition.
