Description

Technical Field

[0001] The utility model belongs to the technical field of wire stranding moulds, and in particular relates to a wire stranding mould with a cooling capability. Background Art

[0002] A stranding die is a tool or equipment used to make stranded wires. Stranded wires are a structure formed by twisting multiple wires or ropes together, and have greater strength and durability. In the traditional cable conductor stranding process, the stranding equipment used is used. The single wire is twisted by the rotation of the stranding cage and the tension of the wire reel. The conventional drawing or rolling die is made of iron or steel. The die mouth and its inner surface are treated with tungsten steel or nano, diamond and other coatings. When used for a long time, a large amount of heat is generated due to the physical forces such as drawing and extrusion during the single-wire stranding process. This heat is concentrated on the die. The long-term high temperature condition greatly reduces the life of the die. The inner coating or treatment layer is easy to make the copper powder or aluminum powder in the stranding process adhere to the die mouth due to the high temperature. First, the bonded dust is easy to be twisted out with the gap between the strands, which may cause the conductor burr to break in the subsequent insulation production process. Second, due to the long-term bonding of copper and aluminum powder, the conductor is easily broken during the stranding process. In the industry, other factories mostly use dripping on the die to cool down.

[0003] The prior art discloses a wire twisting die, with the announcement number CN212380204U, an upper die and a lower die, wherein the upper die has an upper contact surface, and the lower die has a lower contact surface, both of which are curved surfaces, and the upper contact surface and the lower contact surface are tightly attached together; the upper contact surface is provided with an upper groove, and the lower contact surface is provided with a lower groove; when the upper contact surface and the lower contact surface are tightly attached together, the upper groove and the lower groove constitute a cable twisting channel, and when the conductor monofilament passes through the cable twisting channel of the utility model, since the joint seams on both sides of the cable twisting channel are curved, the straight conductor monofilament will not enter the joint seams on both sides of the cable twisting channel, thereby ensuring the quality of the product and improving the production efficiency. The problem existing in the above technology is that the wire twisting die will generate heat during use. Although it can produce twisted wires, it cannot cool the wire twisting die. Utility Model Content

[0004] In view of the problems existing in the prior art, the utility model provides a stranding die with a cooling capability, which can overcome the above problems or at least partially solve the above problems.

[0005] The utility model is implemented as follows: a stranded wire mold with a cooling ability comprises a stranded wire mold and two cooling devices, the stranded wire mold comprises an upper mold sleeve, a lower mold sleeve, an upper mold and a lower mold, the upper mold is installed inside the upper mold sleeve, the lower mold is installed inside the lower mold sleeve, the two cooling devices are respectively located inside the upper mold sleeve and the lower mold sleeve, the bottom cooling device comprises a cooling pipe, a micro booster pump, a shell and a cover plate, the cooling pipe is fixed inside the lower mold sleeve, the rear side of the shell is fixedly connected to the left side of the front side of the lower mold sleeve, the rear side of the micro booster pump is fixedly connected to the rear side of the shell, the four corners of the cover plate are fixedly connected to the front side of the shell by bolts, and the two ends of the cooling pipe are respectively fixedly connected to the water inlet and the water outlet of the micro booster pump;

[0006] The stranded wire mould is used for manufacturing stranded wire;

[0007] The two cooling devices are used to cool the interior of the upper die sleeve and the lower die sleeve.

Through the multiple heat-conducting blocks, the cooling device can discharge the heat from the upper mold sleeve and the lower mold sleeve, and the upper mold sleeve and the lower mold sleeve can be quickly fixed or separated through the four positioning components.

[0009] In order to quickly fix or separate the plug-in block and the fixed block, preferably, the positioning assembly includes a positioning block, two round rods, a pull rod and a return spring. The surfaces of the two round rods and the positioning block can be movably connected to the interior of the cavity. The rear sides of the two round rods are respectively fixedly connected to the top and bottom of the front side of the positioning block, the rear side of the return spring is respectively fixedly connected to the front side of the positioning block, the front side of the return spring is fixedly connected to the front side of the inner wall of the cavity, and the front sides of the two round rods are respectively fixedly connected to the top and bottom of the rear side of the pull rod.

[0010] In order to facilitate the discharge of heat from the inside of the shell, preferably, multiple heat dissipation holes are opened on the left and right sides of the shell and are evenly distributed for ventilating the inside of the shell. Through the multiple heat dissipation holes, the micro booster pump will generate heat during operation and when the temperature is reduced by the cooling pipe. The multiple heat dissipation holes can discharge the heat, and cooling water or cooling oil can flow inside the cooling pipe.

[0011] In order to further improve the heat dissipation effect of the micro booster pump, preferably, a through hole is opened inside the cover plate, and a radiator is fixedly connected to the rear side of the four corners of the through hole by bolts. By using the radiator inside the through hole, the heat generated by the micro booster pump can be drawn forward, thereby improving the heat dissipation effect of the micro booster pump.

Through the positioning block, the rear side of the positioning block is moved to the interior of the plug-in block or out of the interior of the plug-in block, so that the fixed block and the plug-in block can be fixed or separated, thereby achieving the fixing or separation of the upper mold sleeve and the lower mold sleeve.

By making the surface of the positioning block in close contact with the interior of the fixed block and the plug-in block, loosening of the fixed block and the plug-in block after being fixed is avoided, thereby preventing loosening of the connection between the upper mold sleeve and the lower mold sleeve.

[0026] The working principle of this utility model:

[0027] When the stranding die 1 is in use, the two micro booster pumps 2b are operated to circulate the cooling water or cooling oil in the two cooling pipes 2a, thereby cooling the interior of the upper die sleeve 1a and the lower die sleeve 1b. The two radiators 10 are operated to discharge the heat generated by the two micro booster pumps 2b in the two shells 2c. When it is necessary to separate the upper die sleeve 1a from the lower die sleeve 1b, the pull rod 703 is pulled forward by manpower to move the two round rods 702 forward. The two round rods 702 The positioning block 701 will move forward and move out from the inside of the plug-in block 4. At this time, the upper mold sleeve 1a can drive the plug-in block 4 to move upward, so that the upper mold sleeve 1a is out of contact with the lower mold sleeve 1b, and the plug-in block 4 is out of contact with the fixed block 5. When it is necessary to connect and fix the upper mold sleeve 1a with the lower mold sleeve 1b, the positioning block 701 moves forward to deform the reset spring 704. After the pull rod 703 is released, the elastic action of the reset spring 704 will cause the rear side of the positioning block 701 to rebound to the inside of the plug-in block 4, thereby connecting and fixing the upper mold sleeve 1a with the lower mold sleeve 1b.
