Description

Technical Field

[0001] The utility model relates to the field of annealing equipment, in particular to a double-wire annealing furnace. Background Art

[0002] Wire annealing equipment is primarily used for softening, stress relief, and structural improvement of metal wires. Existing wire annealing equipment can generally only perform single-wire annealing. When multiple strands of wire need to be annealed, the strands are typically wound onto reels and placed in an annealing furnace. This furnace annealing process has numerous drawbacks: Because the strands are wound overlappingly on the reels, the strands are heated unevenly inside and outside, cooling at inconsistent rates. This results in inconsistent quality across the various layers of the strands after annealing. After furnace annealing, the strands can only cool naturally, which takes a long time and results in low production efficiency. Utility Model Content

[0031] Next, a double-wire annealing furnace in this exemplary embodiment will be further described.

[0032] In one embodiment of the present application, the fixing frame 21 is a hollow box structure, one side of which is a stepped surface, and the two pay-off groups are located on different planes of the stepped surface. The stepped surface of the fixing frame 21 is horizontally stepped, that is, the two pay-off groups are respectively arranged on two adjacent stepped surfaces, with one pay-off group protruding outward relative to the other pay-off group, so that the two pay-off groups do not interfere with each other when paying out the line.

[0033] In one embodiment of the present application, the pay-off assembly includes a pay-off motor 22, a pay-off drum 23, and a pay-off guide wheel 24. The pay-off motor 22 is installed inside the fixed frame 21, that is, inside the hollow box structure, to protect it. The pay-off drum 23 is rotatably connected to the output end of the pay-off motor 22 and is located outside the fixed frame 21; the pay-off guide wheel 24 is rotatably connected to the side wall of the fixed frame 21 and is located above the pay-off drum 23; wherein, the pay-off guide wheels 24 on different planes are respectively on the same plane as their corresponding traction wheels 41. The pay-off is performed via the pay-off drum 23, and the pay-off guide wheel 24 plays a guiding and tensioning role.

[0034] As an example, there are two pay-off guide wheels 24, which are located above the pay-off drum 23 and are spaced apart from each other on the same axis as the pay-off drum 23. The two pay-off guide wheels 24 can increase the tension of the wire and adjust the pay-off height of the wire.

[0035] In one embodiment of the present application, a traction frame 42 is provided between the annealing furnace 3 and the fixed frame 21. The traction frame 42 is fixed to the furnace frame 1. Two traction wheels 41 are rotatably mounted on the top of the traction frame 42, and the two traction wheels 41 are arranged in parallel. The traction wheels 41 are fixedly supported by the traction frame 42, and the height of the traction wheels 41 is set to be consistent with the height of the annealing tube 31 in the annealing furnace 3. This allows the wire to enter the annealing tube 31 at a similar height after being wound on the traction wheel 41, avoiding the height difference causing large friction between the wire and the annealing tube 31, which may lead to wire wear or breakage.

[0036] As an example, two traction wheels 41 are provided to guide the wires. The two traction wheels 41 are provided in parallel and opposite to the two pay-off groups respectively, so that the wires of the two pay-off groups do not interfere with each other when passing through the traction wheels 41.

[0037] In one embodiment of the present application, a first wire rack 52 is provided on the inner wall of the cooling box 5, a first fixed shaft 53 is passed through the first wire rack 52, and two first wire wheels 51 are rotatably set on the first fixed shaft 53; a second wire rack 55 is provided on the outer wall of the cooling box 5 on one side close to the annealing furnace 3, a second fixed shaft 56 is passed through the second wire rack 55, and two second wire wheels 54 are rotatably set on the second fixed shaft 56.

[0038] The first wire rack 52 fixes and supports the two first wire wheels 51, fixing the two first wire wheels 51 in the middle position of the cooling box 5, and the fixing surface of the first wire rack 52 is inclined to the side wall of the cooling box 5, so that the two first wire wheels 51 are slightly tilted, which facilitates guiding the wire to the second wire wheel 54.

[0039] The second wire pulley 54 is arranged at the top corner of the cooling box 5 on the side close to the annealing furnace 3, and is supported and fixed by the second wire rack 55. It is also arranged to be slightly inclined and opposite to the two first wire pulleys 51 so that the wires do not interfere with each other when being led out. The second wire pulley 54 can lead the wires out of the cooling box 5 and pull the wires back to the side wall of the grate 1 for winding, which can make the entire mechanism compact and small in size.

[0040] As an example, the cooling box 5 is provided with a water inlet and a water outlet. Cooling water is introduced through the water inlet, and the used cooling water is discharged through the water outlet, so that low-temperature cooling water is always maintained in the cooling box 5 to cool the annealed wire in time.

[0041] As an example, a positioning plate 57 is provided within the cooling box 5 between the first wire pulley 51 and the second wire pulley 54. The positioning plate 57 is mounted to the inner wall of the cooling box 5 via a fixing plate. A U-shaped hole is defined at the top of the positioning plate 57 for the wire to pass through. Providing the positioning plate 57 between the first wire pulley 51 and the second wire pulley 54 provides positioning and guidance for the wire as it is drawn out of the cooling box 5, while also facilitating operation.

[0042] In one embodiment of the present application, the wire take-up assembly includes a wire take-up motor 61, a wire take-up drum 62, and a wire take-up guide wheel 63. The wire take-up motor 61 is installed inside the grate 1. The wire take-up drum 62 is rotatably connected to the output end of the wire take-up motor 61 and is located outside the grate 1. The wire take-up guide wheel 63 is rotatably arranged on the side wall of the grate 1 and is located between the wire take-up drum 62 and the second wire pulley 54. The wire take-up motor 61 drives the wire take-up drum 62 to rotate, thereby driving the wire to be wound. The wire is wound around the wire take-up guide wheel 63, which supports and guides the wire, allowing the wire to be stably wound on the wire take-up drum 62.

[0043] As an example, two take-up groups are disposed one above the other on the sidewall of the grate 1, and have different protrusion lengths relative to the sidewall of the grate 1, so that two wires can be taken up simultaneously without interfering with each other. Each take-up group is equipped with multiple take-up guide wheels 63 that are staggered and arranged in parallel in the same plane. Specifically, each group can be equipped with three take-up guide wheels 63. The three take-up guide wheels 63 are located in the same vertical plane and are staggered within the vertical plane. After the wire is tensioned, it is quickly reeled up by the take-up drum 62.

[0044] In one embodiment of the present application, two sets of moving mechanisms are further provided in the grate 1, and the moving mechanisms include a moving motor 71, a threaded rod 72 and a moving block 73. The moving motor 71 is fixed in the grate 1, the threaded rod 72 is transmission-connected to the moving motor 71, the moving block 73 is threadedly connected to the threaded rod 72, and the wire-taking motor 61 is installed on the top of the moving block 73; wherein, the axial direction of the threaded rod 72 is parallel to the axial direction of the wire-taking motor 61.

[0045] As an example, two sets of movable mechanisms are arranged one above the other, corresponding to the two wire take-up groups. A movable motor 71 drives the threaded rod 72 to rotate, thereby driving a movable block 73 to move axially along the threaded rod 72. The movable block 73 then drives the wire take-up motor 61 on top of it to move axially, thereby adjusting the extension of the wire take-up drum 62 from the side wall of the grate 1. This not only adjusts the wire take-up tension, but also ensures that the wire take-up drum 62 fully covers the wire, preventing the wire from being wound around the same position on the take-up drum 62 during winding.

[0046] In one embodiment of the present application, an ammonia decomposition box 8 is further provided within the furnace frame 1. The ammonia decomposition box 8 is located below the cooling box 5 and is connected to the annealing tube 31 via an air pipe. Specifically, a through hole 58 is provided in the side wall of the cooling box 5, and the annealing tube 31 is provided with an air pipe connector 311. One end of the air pipe is connected to the ammonia decomposition box 8, and the other end passes through the through hole 58 and is connected to the air pipe connector 311. The ammonia decomposition box 8 can decompose the protective gas. Passing the protective gas into the outlet end of the annealing tube 31 effectively prevents oxidation of the wire after annealing, thereby improving the quality of the annealed metal wire.

[0047] In one embodiment of the present application, an electric control box 9 and a temperature control panel are provided in the furnace rack 1, and a touch screen display 11 is provided on the side wall of the furnace rack 1. The temperature control panel is electrically connected to the electric control box 9 and the annealing furnace 3 respectively; the electric control box 9 is also electrically connected to the touch screen display 11, the pay-off group and the take-up group respectively. By setting up an electric control box 9 to control the automation of each structure, automatic pay-off, annealing, cooling and take-up of wires are realized, manual operation is reduced, and production efficiency and product quality are improved. By setting up a temperature control panel and connecting it to the electric control box 9, a temperature sensor is set in the annealing furnace 3 to monitor the temperature in real time, the annealing temperature can be accurately controlled to ensure the stability of product quality. By setting up a touch screen display 11 and adopting a human-machine interface operating system, the operation is simple, convenient and easy to master.

[0048] Finally, it should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or terminal device.
