Description

Technical Field

[0001] This utility model relates to the field of annealing equipment technology, and in particular to an anti-oxidation annealing equipment for metal guide wires. Background Technology

[0002] Currently, the conductive materials used in wire and cable production are mainly copper alloy wire and copper wire. As conductor materials for installation wires and low, medium and high voltage cables, copper wire and copper alloy wire must undergo an annealing process, thus requiring the use of annealing equipment.

[0003] In the prior art, the metal guide wire generates considerable heat during the heating and annealing stages because the metal guide wire needs to be heated before annealing. However, since the heat generated during the heating stage can only serve as a heating source for the metal guide wire, it results in the loss and waste of thermal energy.

[0004] To address this issue, an anti-oxidation annealing device for metal guide wires was proposed, which possesses the advantages of anti-oxidation and heat reuse, thereby solving the problems mentioned in the background technology. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a metal guide wire anti-oxidation annealing device.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a metal guide wire anti-oxidation annealing device, comprising a frame, wherein a preheating box, a heating box, and an annealing box are welded sequentially from left to right inside the frame, and both ends of the frame are respectively provided with passage openings. Two guide wheels are rotatably installed in the passage openings. The preheating box, heating box, and annealing box are interconnected, and exhaust pipes are respectively connected to the top of the preheating box, heating box, and annealing box. A high-temperature fan is installed on the surface of the exhaust pipe of the heating box, and the exhaust pipe of the heating box extends to the inside of the preheating box. A cylinder is connected to the tail end of the exhaust pipe of the heating box. Two ceramic heaters are symmetrically installed inside the heating chamber, and two annealing assemblies are symmetrically installed inside the annealing chamber. Each of the two annealing assemblies has a cooling fan fixed inside. Cooling pipes are arranged between the two annealing assemblies, and the surface of the cooling pipes has two serpentine sections corresponding to the annealing assemblies. The two serpentine sections of the cooling pipes are attached to the facing surfaces of the two annealing assemblies. An inert gas storage tank is fixed at the bottom of the frame, and the outlet of the inert gas storage tank is connected to a gas guide pipe. One end of the gas guide pipe is connected to two branch pipes through a tee, and the two branch pipes are respectively connected to the heating chamber and the annealing chamber.

[0007] As a further description of the above technical solution: the preheating box, heating box and annealing box are all provided with side openings, and the outer surface of the side openings is fitted with sealing caps. A set of fixing blocks are welded to each side of the preheating box, heating box and annealing box in pairs, and bolts connected to the sealing caps are inserted through the top surface of the fixing blocks. The side openings are connected to both ends of the preheating box, heating box and annealing box, and the connecting ports are interconnected with the side openings. The side of the cylinder facing the side openings is provided with a strip-shaped notch.

[0008] As a further description of the above technical solution: both ends of the cooling pipe pass through the annealing box and are connected to an external circulating water tank, and a water pump is installed on the surface of the cooling pipe, and cold water circulates inside the cooling pipe.

[0009] As a further description of the above technical solution: the top of the cylinder is welded with several support rods, and the tops of the support rods are all connected to the inner wall of the preheating box.

[0010] As a further description of the above technical solution: metal wire mesh is welded to the opposite ends of the two annealing components, and the metal wire mesh is in contact with the serpentine part of the cooling pipe.

[0011] As a further description of the above technical solution: the preheating box, heating box, annealing box and the passage are arranged linearly, and metal guide wires are transversely inserted in the preheating box, heating box, annealing box and the passage.

[0012] This utility model has the following beneficial effects:

[0013] In this invention, a preheating box, a heating box, and an annealing box are arranged linearly within a frame. As the metal guide wire continuously passes through the preheating box, the heating box, and the annealing box, a high-temperature fan on the surface of the exhaust pipe at the heating box is activated, causing the hot gas inside the heating box to transfer to the cylinder of the preheating box. This provides targeted preheating for the metal guide wire passing through the cylinder, allowing the metal guide wire to undergo preheating, heating, and annealing treatments in sequence. At this time, inert gas from the inert gas storage tank is introduced into the heating box and the annealing box through a gas guide pipe and two branch pipes, causing the inert gas to drive away the air and fill the heating box and the annealing box. This satisfies the oxidation resistance requirements of the metal guide wire during the heating and annealing stages while also enabling the reuse of heat from the heating box.

[0014] In this invention, a set of side openings, sealing covers, and fixing blocks are respectively provided on the sides of the preheating box, heating box, and annealing box. Bolts connected to the side of the sealing cover are inserted through the fixing blocks. A strip-shaped notch is opened on the cylinder of the preheating box corresponding to the side opening. By unlocking the bolts inserted through the fixing blocks, the sealing cover can be released from the state of obstruction of the side opening, so that the metal guide wire can be placed in the cylinder of the preheating box, between the two ceramic heaters of the heating box, and between the two sets of annealing components of the annealing box. While ensuring the sealing of the preheating box, heating box, and annealing box, it is easy to load the metal guide wire in the initial stage, making it convenient to use.

Figure 1-3As shown, the metal guide wire anti-oxidation annealing device according to an embodiment of the present invention includes a frame 1.

Cooling pipes 18 are arranged between the two annealing components 17, and the surface of the cooling pipes 18 corresponds to the annealing... The fire assembly 17 is provided with two serpentine sections 20, and the two serpentine sections 20 of the cooling pipe 18 are attached to the opposing surfaces of the two annealing assemblies 17. An inert gas storage tank 12 is fixed at the bottom of the frame 1, and the outlet end of the inert gas storage tank 12 is connected to a gas guide pipe 13. One end of the gas guide pipe 13 is connected to two branch pipes 14 through a tee, and the two branch pipes 14 are respectively connected to the heating box 3 and the annealing box 4.

The wiring diagram of the power components and the power supply are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail. The function of the exhaust pipe 5 in this device to extract hot gas can also be used to avoid the situation where the gas pressure in the heating box 3 is too high due to the continuous introduction of inert gas.

[0023] In one embodiment, the preheating box 2, heating box 3, and annealing box 4 each have a side opening 9, and a sealing cover 10 is attached to the outer surface of the side opening 9. A set of fixing blocks 11 are welded to each side of the preheating box 2, heating box 3, and annealing box 4 in pairs, and bolts connected to the sealing cover 10 are inserted through the top surface of the fixing blocks 11. The side opening 9 and both ends of the preheating box 2, heating box 3, and annealing box 4 have connecting ports, and the connecting ports are interconnected with the side opening 9. A strip-shaped notch 21 is opened on the side of the cylinder 15 facing the side opening 9. By unlocking the bolts inserted on the fixing blocks 11, the sealing cover 10 can be released from the obstruction state of the side opening 9, so that the metal guide wire can be placed in the cylinder 15 of the preheating box 2, between the two ceramic heaters 16 of the heating box 3, between the two sets of annealing components 17 of the annealing box 4, and between the two guide wheels 8 in the through port 7, which facilitates the loading and installation of the metal guide wire.

[0024] In one embodiment, both ends of the cooling pipe 18 pass through the annealing chamber 4 and are connected to an external circulating water tank. A water pump is installed on the surface of the cooling pipe 18, and cold water circulates inside the cooling pipe 18. In this way, it is easy for cold water to circulate inside the cooling pipe 18.

[0026] In one embodiment, metal wire mesh is welded to the opposing ends of the two annealing components 17, and the metal wire mesh is in contact with the serpentine portion 20 of the cooling pipe 18.

[0028] Working principle:

[0029] In use, firstly, by unlocking the bolts inserted on the fixing block 11, the sealing cover 10 is released from its obstruction of the side opening 9, allowing the metal guide wire to be placed inside the cylinder 15 of the preheating box 2, between the two ceramic heaters 16 of the heating box 3, between the two sets of annealing components 17 of the annealing box 4, and between the two guide wheels 8 inside the passage 7. Then, the two ends of the cooling pipe 18 inside the annealing box 4 are connected to the external circulating water tank pipeline, allowing cold water to circulate within the cooling pipe 18. The cooling fan 19 of the annealing component 17 is then activated to blow cold air to the metal guide wire conveying area for annealing cooling. As the metal guide wire continuously passes through the preheating box 2... The heating chamber 3 and annealing chamber 4 are connected by a high-temperature fan 6 on the surface of the exhaust pipe 5 at the heating chamber 3. This transfers the hot gas inside the heating chamber 3 to the cylinder 15 of the preheating chamber 2, where the metal guide wire passing through the cylinder 15 is preheated. The metal guide wire is then subjected to preheating, heating, and annealing treatment in sequence. At this time, the inert gas discharged from the inert gas storage tank 12 is introduced into the heating chamber 3 and annealing chamber 4 through the gas guide pipe 13 and two branch pipes 14. This allows the inert gas to drive out the air and fill the heating chamber 3 and annealing chamber 4, thus satisfying the oxidation resistance of the metal guide wire during the heating and annealing stages while also enabling the reuse of heat in the heating chamber 3.
