Description

Technical Field

[0001] This utility model relates to the field of aluminum-clad steel wire production technology, specifically to a multi-segment temperature-controlled composite forming device for high heat-resistant aluminum-clad steel strand. Background Technology

[0002] Aluminum-clad steel wire is a bimetallic conductor in which a layer of aluminum is uniformly, continuously, and tightly wrapped around a round steel wire. During the production process, the steel wire is hot-dip galvanized, making it suitable for use as a catenary, reinforcing core, or overhead transmission cable. The galvanized wire is then twisted and stabilized at a specific temperature to obtain the finished aluminum-clad steel cable. Existing flexible aluminum-clad steel wire production lines include a conveying device, drawing rollers, a heating device, and an extrusion device. The steel wire is conveyed sequentially through the first drawing roller, the second drawing roller, the heating device, the extrusion roller, and the winding machine. The produced aluminum-clad steel wire has high strength and good corrosion resistance, but aluminum layer peeling still occurs.

[0003] The relevant reference CN210995855U discloses a continuous aluminum-clad steel coating production line. The steel wire sequentially passes through a buffer frame, a wire guiding mechanism, a first wire straightening device, and a second wire straightening device. It is then heated to a certain temperature by an induction heating device and fed into an extruder for aluminum-clad steel coating. The processed aluminum-clad steel wire is then sequentially cooled by a cooling device, measured by a diameter gauge, pulled by a wheel-type traction mechanism, buffered by a shock absorber, and finally taken up by a take-up machine, improving the yield rate. However, the bonding effect between the steel core surface and the aluminum layer is relatively poor. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a high heat-resistant aluminum-clad steel strand multi-segment temperature-controlled composite molding device for improving the composite effect of aluminum layer in aluminum-clad steel strand.

[0005] To address the above technical problems, this utility model provides a multi-segment temperature-controlled composite forming device for high heat-resistant aluminum-clad steel strand, including a preheating mold cavity, a heating mold cavity, an extrusion mold cavity, and a cooling section. The preheating mold cavity is equipped with a removal ring and an induction heating device I. The removal ring is located on one side of the induction heating device I, and an infrared thermometer probe is located on the other side of the induction heating device I. The infrared thermometer probe is fixed to the inner wall of the preheating mold cavity and faces the steel wire. The heating mold cavity is equipped with a plating tank and an induction heating device II. A temperature sensor is located on one side of the induction heating device II and is fixed to the inner wall of the heating mold cavity. The cooling section provides room temperature cooling.

[0006] By adopting the above technical solution, when processing aluminum-clad steel strands, the mold cavity is first preheated, then heated, and finally cooled. Impurities are removed by a removal ring, and a plating tank is coated with a flux. An infrared thermometer probe and a temperature sensor monitor the temperature. Through precise segmented temperature control and auxiliary components, the aluminum layer composite effect of the aluminum-clad steel strands is improved, and the high efficiency, stability, and quality of aluminum-steel composite production are achieved.

[0007] Preferably, the induction heating device I is equipped with a water cooling circulation device I.

[0010] By adopting the above technical solution, the guide wheels I at the inlet and outlet of the induction heating device I guide the steel wire to pass smoothly through the induction heating device I, avoiding deviation that could lead to uneven heating.

[0011] Preferably, guide wheels II are provided at both the inlet and outlet of the induction heating device II.

[0012] By adopting the above technical solution, the guide wheels II at the inlet and outlet of the induction heating device II guide the steel wire to smoothly enter and leave the heating mold cavity, preventing the steel wire from deviating or tangling.

[0013] Preferably, the induction heating device II is equipped with a water cooling circulation device II.

[0014] By adopting the above technical solution, the water-cooled circulation device II cools down the induction heating device II, preventing the equipment from overheating and being damaged, and improving the service life of the device.

[0015] Preferably, the cooling section is equipped with a positive traction wheel and a negative traction wheel. The positive traction wheel and the negative traction wheel have the same structure, their wheel edges are in contact, and they are installed on the same plane.

[0016] By adopting the above technical solution, the positive traction wheel and the auxiliary traction wheel pull synchronously, which reduces the relative slippage between the steel wire and the traction wheel and reduces the risk of scratches on the surface of the steel wire.

[0017] Preferably, the traction motor is mounted on the positive traction wheel via a rotating shaft.

[0018] By adopting the above technical solution, the traction motor directly drives the positive traction wheel through the rotating shaft, eliminating the need for traditional intermediate transmission structures such as belts, gears, or chains, and significantly improving power transmission efficiency.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. In the processing of aluminum-clad steel strands, this utility model first preheats the mold cavity, then heats the mold cavity, and finally cools it in the cooling section. It is supplemented by a cleanup ring to remove impurities, a plating tank to coat with a flux, and an infrared thermometer probe and a temperature sensor to monitor the temperature. Through precise segmented temperature control and auxiliary components, the composite effect of the aluminum layer of the aluminum-clad steel strands is improved, and the high efficiency, stability and quality of aluminum-steel composite production are achieved.

Detailed Implementation

[0024] like Figure 1 , 2As shown, a multi-segment temperature-controlled composite forming device for high heat-resistant aluminum-clad steel strand includes a preheating mold cavity 1, a heating mold cavity 2, an extrusion mold cavity 3, and a cooling section 4. An aluminum rod storage device 20 is fixedly installed on the inner wall of the heating mold cavity 2. An extrusion roller 19 is installed in the extrusion mold cavity 3, and the extrusion roller 19 has an extrusion groove. The aluminum rod storage device 20 and the extrusion mold cavity 3 are existing technologies. A removal ring 5 and an induction heating device I 6 are installed in the preheating mold cavity 1. The removal ring 5 removes impurities from the surface of the steel wire, ensuring surface cleanliness during heating. The removal ring 5 is located to the left of the induction heating device I 6, and an infrared thermometer probe 7 is installed to the right of the induction heating device I 6; the infrared thermometer probe 7 is fixed to the inner wall of the preheating mold cavity 1 and faces the steel wire. A plating tank 8 and an induction heating device II 9 are installed in the heating mold cavity 2. The flux in the plating tank 8 can form a protective layer on the surface of the steel wire, isolating it from air, while increasing surface activity and promoting aluminum-steel composite bonding. A temperature sensor 10 is installed on one side of the induction heating device II9. The temperature sensor 10 is fixed to the inner wall of the heating mold cavity 2 to ensure that the heating temperature is controlled within a suitable range. The cooling section 4 is room temperature cooling. In the processing of aluminum-clad steel strands, this application first preheats the mold cavity 1, then heats the mold cavity 2, and finally cools it in the cooling section. Impurities are removed by the impurity removal ring 5, and the plating tank 8 is coated with a flux. The infrared thermometer probe 7 and the temperature sensor 10 monitor the temperature. Through precise segmented temperature control and auxiliary components, the aluminum layer composite effect of the aluminum-clad steel strands is improved, and the high efficiency, stability, and quality of aluminum-steel composite production are achieved.

[0025] A water-cooling circulation device I11 is installed on the induction heating device I6. The water-cooling circulation device I11 cools the induction heating device I6, preventing overheating damage and extending the service life of the device.

[0026] Guide wheels I12 are installed at both the inlet and outlet of the induction heating device I6. These guide the steel wire to pass smoothly through the induction heating device I6, preventing deviation and uneven heating.

[0027] Guide wheels II13 are provided at the inlet and outlet of the induction heating device II9 to guide the steel wire smoothly into and out of the heating mold cavity 2, preventing the steel wire from deviating or tangling.

[0028] A water-cooling circulation device II14 is installed on the induction heating device II9. The water-cooling circulation device II14 cools the induction heating device II9, preventing overheating damage and extending the device's lifespan. The water-cooling circulation device I11 and the water-cooling circulation device II14 have the same structure.

[0029] Cooling section 4 is equipped with a positive traction wheel 15 and a negative traction wheel 16. The positive traction wheel 15 and the negative traction wheel 16 have the same structure, with their wheel edges fitting together and mounted on the same plane. The positive traction wheel 15 and the negative traction wheel 16 provide synchronous traction, reducing the relative slippage between the steel wire and the traction wheel and lowering the risk of scratches on the steel wire surface.

[0030] The positive traction wheel 15 is mounted with a traction motor 18 via a shaft 17, and the traction motor 18 is installed on the inner wall of the cooling section 4. The traction motor 18 directly drives the positive traction wheel 15 via the shaft 17, eliminating the need for traditional intermediate transmission structures such as belts, gears, or chains. Traditional intermediate transmission structures suffer energy loss due to friction, elastic deformation, and other factors, while direct drive almost eliminates such losses, significantly improving power transmission efficiency.

[0031] During operation, the steel wire passes through the impurity removal ring 5, is preheated by the induction heating device I 6, and then coated with a flux in the plating tank 8, which facilitates better aluminum-steel bonding. The flux-coated steel wire and aluminum rod are heated together by the induction heating device II 9, and then extruded through the extrusion groove in the extrusion die cavity 3 to form aluminum-clad steel wire. The aluminum-clad steel wire is then pulled to the next production section by the positive traction wheel 15 and the auxiliary traction wheel 16.
