Description

Technical Field

[0001] This utility model relates to the technical field of wire tube annealing machines, specifically a wire tube annealing machine. Background Technology

[0002] In traditional annealing processes, high-temperature copper wires readily react with oxygen to form an oxide layer, leading to increased resistivity and decreased mechanical properties. While existing technologies suppress oxidation through nitrogen filling, the direct emission of high-temperature exhaust gases results in energy waste. This solution optimizes the gas circulation system to achieve the dual goals of oxidation protection and energy reduction. Utility Model Content

[0003] To solve the above problems, namely the problems mentioned in the background art, this utility model proposes a wire tube type annealing machine, including a main body and a wire rack. The wire rack is installed at the entrance of the main body. A heating mechanism is installed inside the main body. Stainless steel pipes are symmetrically installed on both sides of the heating mechanism. A connector for connecting a gas pipe is installed in the middle part of the stainless steel pipe installed on the outlet side of the heating mechanism. A gas supply mechanism for conveying nitrogen is installed on the main body, and the gas supply mechanism is connected to the stainless steel pipe through the gas pipe and the connector.

[0004] The gas supply mechanism includes a gas storage tank for storing compressed nitrogen, and the gas storage tank is equipped with a pressure reducing valve, which is connected to a stainless steel pipe through a gas pipe and a connector.

[0005] A lip seal ring is installed on the side of the stainless steel tube away from the heating mechanism.

[0006] A further feature of this invention is that an air pump is installed on one side of the air storage tank, and two valves are installed on the outlet of the air pump via a tee. The air storage tank is connected to one of the valves via an air pipe, and the inlet of the air pump is connected to a stainless steel pipe installed at the inlet of the heat dissipation mechanism via an air pipe and a connector.

[0007] A further feature of this invention is that the heating mechanism includes a flip-open box, a ceramic sleeve, and an electromagnetic induction coil. The box is installed in the main body, the ceramic sleeve is snapped into the box, two stainless steel tubes are inserted into both ends of the ceramic sleeve, and the stainless steel tubes are installed on the box through connecting flanges. The electromagnetic induction coil is wound around the outer wall of the ceramic sleeve.

[0008] A further feature of this invention is that the lip sealing ring includes a rubber ring, a lip, and a metal skeleton. The rubber ring is snapped onto the inner wall of the stainless steel tube on the side away from the heating mechanism. The lip is disposed on the inner wall of the rubber ring. A hollow cylindrical metal skeleton is embedded inside the rubber ring, and the end of the metal skeleton is bent inward and extends into the lip.

[0009] A further feature of this invention is that the cable tray is configured as a multi-roller cable tray with adjustable conductor tension.

[0010] The beneficial technical effects of this utility model are as follows: by supplying nitrogen through the gas supply mechanism, a slightly positive pressure environment of nitrogen in the heating space is ensured, so as to prevent the wire from being oxidized during the annealing process and ensure the quality of the product. At the same time, most of the nitrogen can be recycled, reducing nitrogen consumption and lowering operating costs. Through gas heat exchange, not only is the cooling time improved and the wire preheated to a certain extent, shortening the wire annealing time and enabling the equipment to increase the wire supply speed, but it can also improve the speed of equipment state transition during the initial operation and improve work efficiency.

[0015] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0016] This utility model proposes a wire tube type annealing machine. After the wire passes through the wire guide 4 to adjust its input position and tension, it enters the heating mechanism 2 of the main body 1 for the annealing process. The heating mechanism 2 consists of a box 201, a ceramic sleeve 202, and an electromagnetic induction coil 203. The box 201 is installed in the main body 1 and can be flipped open. Annular slots are opened on both sides. The two ends of the ceramic sleeve 202 are locked in the annular slots. The ceramic sleeve 202 can be replaced by flipping open the box 201. The electromagnetic induction coil 203 is wound in the ceramic sleeve 202 and is used to heat the wire passing through the ceramic sleeve 202.

[0017] The wires entering and exiting the heating mechanism 2 must pass through the stainless steel pipes 3 at both ends of the heating mechanism 2. The end of the stainless steel pipe 3 is inserted into the end of the ceramic sleeve 202 and fixed to the housing 201 through the connecting flange. All gaps at the joints are sealed by filling with sealing strips. The other end of the stainless steel pipe 3 is connected to the inlet and outlet of the main body 1 through the connecting flange.

[0018] A gas supply mechanism is installed on the main body 1, and nitrogen is supplied through a stainless steel pipe located on the outlet side of the heating mechanism 2. A lip seal ring 8 is installed on the side of the stainless steel pipe 3 connected to the main body 1 to fill the gap between the wire and the stainless steel pipe 3, preventing a large amount of nitrogen leakage. This allows the gas to fill the two stainless steel pipes 3 and the heating chamber of the heating mechanism 2 and maintain a slightly positive pressure state, preventing the surface of the wire from oxidizing after heating, which would affect product quality. At the same time, after the nitrogen passes through the heating mechanism 2 and its temperature is increased, it enters the stainless steel pipe located on the inlet side to preheat the wire at the inlet of the heating mechanism 2, shortening the wire heating time and increasing the wire supply speed.

[0019] The gas supply mechanism consists of a gas storage tank 6 and a pressure reducing valve 5. After the high-pressure nitrogen gas is reduced in pressure by the pressure reducing valve 5, it enters the stainless steel pipe at the outlet through the gas pipe and connector to help cool the heated wire. The temperature of the gas after heat exchange rises and enters the heating mechanism 2 to avoid insufficient heating of the wire affecting the annealing effect. Finally, it enters the stainless steel pipe 3 on the other side to preheat the unheated wire.

[0020] An air pump is installed on the main body 1 and connected to the stainless steel pipe 3 on the inlet side via an air pipe and connector. Gas is drawn at a rate lower than the gas supply rate to maintain a positive pressure in the heating mechanism 2 and the stainless steel pipe 4, preventing outside air from entering. At the same time, the drawn gas can be pressurized and transported back to the gas storage tank 6 through a tee and air pipe, which can recover most of the nitrogen and reduce nitrogen consumption. Valves are installed on both sides of the tee, one connected to the gas storage tank 6 and the other connected to the outside. When the equipment is initially started, the valve on the gas storage tank 6 is closed, the valve connected to the outside is opened, and the air pump is run. This can accelerate the discharge of air from the heating mechanism 2 and the stainless steel pipe 3, and maintain the nitrogen filling level in the equipment by supplying nitrogen, which greatly increases the speed at which the equipment can transition from the initial start-up state to the processing state.

[0021] A lip sealing ring 8 is installed at the end of the stainless steel pipe 3. A rubber ring 801 is snapped onto the inner wall of the stainless steel pipe 3. A metal skeleton 803 is used to support the rubber ring 801. The end of the metal skeleton 803 is bent and inserted into the lip 802 for support, so as to avoid excessive deformation of the lip 802 and affect the sealing effect.

In particular, the technical features mentioned in the various embodiments can be combined in any manner as long as there is no structural conflict.
