Description

Technical Field

[0001] The utility model relates to the field of metal annealing devices, in particular to an online bright annealing device for copper alloy wires. Background Art

[0002] Bright annealing, commonly known as bright annealing, is mainly done by heating and annealing in a closed space, then slowly cooling the temperature to below 500 degrees Celsius in the closed space and then cooling naturally to achieve brightness without causing decarburization. During ordinary annealing, oxidation and decarburization occur during heating and cooling. Online bright annealing equipment for copper alloy wire is mostly used for eliminating deformation, hardening and recrystallization annealing during the copper tube processing process (drawing or rolling). After the drawing process, the diameter, roundness, internal metallographic structure, surface finish and straightness of the wire or bar meet the raw material processing requirements for the production of standard parts and other metal products.

[0003] However, most of the current copper alloy wire annealing devices are large in size, and a winding structure needs to be added at the end of the device during processing, which makes it inconvenient to use. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides an online bright annealing device for copper alloy wires, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solution: an online bright annealing device for copper alloy wire, comprising an annealing furnace, an inclined bracket being installed at one end of the annealing furnace, a wire taking-up mechanism being provided on the inner side of the inclined bracket, a wire feed pipe being installed at one side end of the annealing furnace close to the inclined bracket, a wire taking-up roller being provided at one side end of the wire taking-up mechanism, a transmission roller being connected to the outer end of the wire taking-up roller via a rotating shaft, a driving motor being installed at one side of the wire taking-up mechanism, a transmission belt being connected between the driving motor and the transmission roller, a heating chamber being installed inside the annealing furnace, a first reversing roller being installed on one side of the heating chamber located inside the annealing furnace, and a second reversing roller being provided directly below the first reversing roller.

[0006] As a further solution of the present invention: a storage compartment is installed inside the annealing furnace below the heating compartment, a closing pad is installed on the inner side of the storage compartment, and a card slot is provided in an array on one side end of the closing pad located close to the first reversing roller.

[0007] As a further solution of the present invention: a fan is installed below the second reversing roller on one side of the annealing furnace, and an air supply pipe is installed on the upper surface of the annealing furnace.

[0008] As a further solution of the present invention: the wire-taking mechanism is provided with a movable bayonet at one side end close to the wire-taking roller, and a positioning bolt is installed between the wire-taking mechanism and the oblique bracket.

[0009] As a further solution of the present invention: the first reversing roller and the second reversing roller are both movably connected to the annealing furnace.

[0010] As a further solution of the present invention: a heating wire is installed inside the heating chamber, and the closing pad is movably connected to the storage compartment.

[0011] As a further solution of the present invention: the air supply pipe is connected to the annealing furnace.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] An upper wire-winding mechanism is added to the wire inlet end of the annealing furnace, which can cooperate with the first reversing roller and the second reversing roller inside the annealing furnace to realize the operations of heating, cooling, rapid cooling and winding of the wire, thereby reducing the footprint of the entire device.

[0014] After the take-up roller is wound as a whole, the take-up mechanism is removed from the inside of the inclined bracket, and the take-up roller can be freely removed from the end of the take-up mechanism, and a new take-up roller can be quickly replaced to carry out the subsequent wire winding process.

[0015] Push the entire closing pad inside the storage compartment, buckle the slot at the end of the closing pad onto the outside of the wire, seal the top of the storage compartment, and inject protective atmosphere into the interior through the air supply pipe to prevent a large amount of atmosphere from leaking out and affecting annealing.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-5 As shown, this embodiment provides an online bright annealing device for copper alloy wire, including an annealing furnace 1, an oblique bracket 4 is installed at one end of the annealing furnace 1, a wire take-up mechanism 5 is provided on the inner side of the oblique bracket 4, a wire feed pipe 2 is installed at one end of the annealing furnace 1 near the oblique bracket 4, a wire take-up roller 501 is provided at one end of the wire take-up mechanism 5, a positioning bolt is installed between the wire take-up mechanism 5 and the oblique bracket 4, a movable bayonet is provided at one end of the wire take-up mechanism 5 near the wire take-up roller 501, and the wire take-up roller 501 is provided with a movable bayonet. The outer end of the take-up mechanism 5 is connected to a transmission roller 502 through a rotating shaft, a drive motor 503 is installed on one side of the take-up mechanism 5, and a transmission belt 504 is connected between the drive motor 503 and the transmission roller 502. A heating chamber 102 is installed inside the annealing furnace 1, and a first reversing roller 103 is installed on one side of the heating chamber 102 inside the annealing furnace 1. A second reversing roller 104 is provided directly below the first reversing roller 103. The first reversing roller 103 and the second reversing roller 104 are both movably connected to the annealing furnace 1.

[0024] like Figure 2-3 As shown, in this embodiment, a storage compartment 101 is installed inside the annealing furnace 1 below the heating compartment 102, a heating wire is installed inside the heating compartment 102, a closing pad 6 is installed on the inner side of the storage compartment 101, the closing pad 6 is movably connected to the storage compartment 101, and the closing pad 6 is located at one end of the side array close to the first reversing roller 103 and is provided with a card slot 601, a fan 7 is installed on one side of the annealing furnace 1 below the second reversing roller 104, and an air supply pipe 3 is installed on the upper surface of the annealing furnace 1, and the air supply pipe 3 is connected to the annealing furnace 1.

[0025] The working principle of the present invention is as follows: when in use, the wire to be processed is extended from the inside of the wire inlet pipe 2 into the inside of the annealing furnace 1, and the wire passes through the inside of the heating chamber 102 as a whole. Then, the wire is passed around the first reversing roller 103 and the second reversing roller 104 as a whole, and then the end of the wire is wound around the outside of the take-up roller 501, and then the driving motor 503 is started to drive the transmission belt 504 to rotate. The rotating transmission belt 504 drives the take-up roller 501 to rotate by driving the transmission roller 502, so that the take-up roller 501 can rewind the wire, and the closing pad 6 is pushed as a whole inside the storage compartment 101, and the slot 601 at the end of the closing pad 6 is buckled as a whole on the outside of the wire, and the storage compartment 101 is positioned above the storage compartment 101. The annealing furnace 1 is closed, the heating wire in the heating chamber 102 heats the wire and injects a protective atmosphere into the interior through the air supply pipe 3, so that the temperature of the wire is slowly cooled in the closed space. When the wire is guided by the first reversing roller 103 and the second reversing roller 104, the wire after heating is pulled to the position below the storage compartment 101, and the fan 7 outside the annealing furnace 1 can blow air to cool the wire again, which can ensure that the wire will have brightness and will not cause decarburization. After the take-up roller 501 is completely wound, the take-up mechanism 5 is removed from the inside of the inclined bracket 4 as a whole, and the take-up roller 501 can be freely disassembled from the end of the take-up mechanism 5 as a whole, and the new take-up roller 501 can be quickly replaced for the subsequent winding of the wire.
