Description

Technical Field

[0001] This utility model relates to the field of iron wire production technology, and more specifically, to an iron wire annealing and softening device. Background Technology

[0002] Iron wire is a basic metal product characterized by high strength, low cost, and ease of processing, and is widely used in various fields such as industry, agriculture, construction, and daily life. Annealing and softening is a key heat treatment step in iron wire production, mainly used to eliminate work hardening caused by cold working such as drawing, and to restore the material's plasticity and flexibility for subsequent processing or to meet the performance requirements of the final product. Currently, pit-type annealing furnaces are commonly used for heat treatment of small batches and multiple specifications of iron wire. The inner wall of the pit-type annealing furnace is lined with heating components such as electric heating wires to ensure uniform heating within the furnace. Typically, the iron wire is collected by winding it onto a wire rack, and then the wire rack and the entire wire are hoisted into the annealing furnace, covered with a sealed lid, and then heated for heat treatment. However, proper alignment is crucial during hoisting. If the alignment is inaccurate or the wire rack shakes, it can easily collide with the inner wall of the annealing furnace, damaging the heating components and affecting the heating effect. Therefore, it is necessary to improve the existing annealing and softening equipment. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an iron wire annealing and softening device. During the process of lowering the wire frame, the bottom surface of the wire frame or the side of the iron wire comes into contact with one or more side baffles and slides down along the side baffles, thereby restricting the downward direction of the wire frame and effectively solving the problem of the wire frame shaking and impacting the furnace wall.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A wire annealing and softening device includes a spheroidizing annealing furnace and an auxiliary positioning component. The auxiliary positioning component is disposed on the furnace opening of the spheroidizing annealing furnace and includes a positioning frame and side baffles. The positioning frame is placed above the furnace opening of the spheroidizing annealing furnace. A passage opening for the wire frame to pass through is provided in the middle of the positioning frame. The passage opening is square. Side baffles are respectively provided on the four sides of the passage opening. The side baffles are inclined and the angle between the side baffles and the horizontal plane is α, 70°≤α≤90°. The four side baffles form a trumpet-shaped guide opening at the passage opening.

[0006] In one embodiment, two positioning rings are symmetrically arranged on the top surface of the positioning frame, and a steel wire rope is arranged between the two positioning rings. One end of the steel wire rope is fixedly connected to one of the positioning rings, and the other end of the steel wire rope is provided with a hook. The steel wire rope is detachably connected to the other positioning ring through the hook.

[0007] In one embodiment, the side baffle is hinged to the positioning frame, and the rotation angle of the side baffle is ≤20°.

[0008] In one embodiment, a torsion spring is provided at the hinge point between the side baffle and the positioning frame.

[0009] In one embodiment, the auxiliary positioning component further includes a guide base plate, which is detachably connected to the bottom surface of the wire frame. The guide base plate is larger than the bottom surface of the wire frame and contacts the side baffle.

[0010] In one embodiment, the guide base plate is disc-shaped, and the side of the guide base plate is curved to reduce the frictional force when in contact with the side baffle.

[0011] In one embodiment, a plurality of balls are evenly arranged on the circumferential side of the guide base plate.

[0012] In summary, this utility model has the following beneficial effects:

[0013] In the process of lowering the wire frame, the bottom surface of the wire frame or the side of the wire comes into contact with one or more side baffles and slides down along the side baffles, thereby restricting the downward direction of the wire frame and effectively solving the problem of the wire frame shaking and impacting the furnace wall.

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] It is worth noting that the directional terms such as "up" and "down" used in this article are all relative to the perspective of the attached figures and are only for the purpose of description. They should not be interpreted as limitations on the technical solutions.

[0018] like Figure 1 As shown, this utility model proposes an annealing and softening device for iron wire, including a spheroidizing annealing furnace 1 and an auxiliary positioning component. The auxiliary positioning component is set on the furnace mouth of the spheroidizing annealing furnace 1. The auxiliary positioning component includes a positioning frame 2 and side baffles 3. The positioning frame 2 is placed above the furnace mouth of the spheroidizing annealing furnace 1. A passage opening is provided in the middle of the positioning frame 2 to facilitate the passage of the wire frame 7. The passage opening is square. Side baffles 3 are respectively set on the four sides of the passage opening. The side baffles 3 are inclined and the angle between the side baffles 3 and the horizontal plane is α, 70°≤α≤90°. The four side baffles 3 form a trumpet-shaped guide opening at the passage opening.

[0019] The spheroidizing annealing furnace 1 of this invention is an existing device. This invention improves upon the existing spheroidizing annealing furnace 1 to solve the problem of the wire frame 7 impacting the inner wall of the furnace 1 during the lifting process. The method of use is as follows: When the wire frame 7 with iron wire needs to be lifted into the spheroidizing annealing furnace 1, first open the furnace cover, place the positioning frame 2 at the furnace opening, ensuring the guide opening formed by the four side baffles 3 is in the middle of the furnace opening. Then, lift the wire frame 7 above the guide opening. During the lowering process, the bottom surface of the wire frame 7 or the side of the iron wire may contact one or more side baffles 3 and slide down along them, thus limiting the descent direction of the wire frame 7 and effectively solving the problem of the wire frame 7 swaying and impacting the furnace wall. After the wire frame 7 is completely placed into the furnace, remove the positioning frame 2, reseal the furnace cover, and the spheroidizing annealing furnace 1 can then perform heat treatment on the iron wire. It is easy to understand that after the heat treatment is completed, the wire frame 7 and the wire will not easily shake during the process of suspending them. The positioning frame 2 is not at the furnace opening and will not obstruct the suspending of the wire frame 7.

[0020] Preferably, to facilitate hoisting the positioning frame 2, two positioning rings 6 are symmetrically arranged on the top surface of the positioning frame 2, and a steel wire rope is installed between the two positioning rings 6. Figure 1 The wire rope is not shown. One end of the wire rope is fixedly connected to one of the positioning rings 6, and the other end of the wire rope is equipped with a hook. The wire rope is detachably connected to the other positioning ring 6 via the hook. It is easy to understand that during the hoisting of the positioning frame 2, the wire rope is positioned between the two positioning rings 6. The hook of the hoisting device, such as an overhead crane, is connected to the wire rope to smoothly lift the positioning frame 2. However, during the hoisting and lowering of the wire frame 7, the end of the wire rope with the hook needs to be separated from the positioning ring 6 to avoid affecting the descent of the wire frame 7.

[0021] In some embodiments, the side baffle 3 is hinged to the positioning frame 2, and the rotation angle of the side baffle 3 is ≤20°. The angle between the side baffle 3 and the horizontal plane is between 70° and 90°. When the side baffle 3 can rotate, the limit position of the side baffle 3 rotating towards the center of the furnace is when the side baffle 3 is perpendicular to the horizontal plane. Therefore, the rotation angle of the side baffle 3 is ≤20°, and the rotation angle is based on the minimum angle between the side baffle 3 and the horizontal plane when the side baffle 3 is tilted.

[0022] During the process of hanging the wire frame 7, the side of the wire frame 7 or the wire comes into contact with the side baffle 3. The side baffle 3 itself can rotate at a certain angle to reduce the impact from the wire frame 7 or the wire.

[0023] Preferably, a torsion spring is provided at the hinge point between the side baffle 3 and the positioning frame 2, so that the side baffle 3 can be reset after being impacted.

[0024] In some embodiments, the auxiliary positioning assembly further includes a guide base plate 4, which is detachably connected to the bottom surface of the wire frame 7. The guide base plate 4 is larger than the bottom surface of the wire frame 7 and contacts the side baffle 3. The guide base plate 4 is installed on the bottom surface of the wire frame 7 and follows the wire frame 7 into and out of the furnace. During the hoisting and lowering of the wire frame 7, the edge of the guide base plate 4 protrudes from the side of the wire frame 7 and the wire. The guide base surface first contacts the side baffle 3, which serves as a limit and prevents the wire from directly impacting the side baffle 3.

[0025] Preferably, the guide base plate 4 is disc-shaped, and its sides are curved to reduce friction with the side baffles 3. The disc-shaped guide base plate 4 reduces the contact area and thus lowers friction regardless of which side baffle 3 it contacts. More preferably, a plurality of ball bearings 5 ​​are evenly distributed on the circumferential side of the guide base plate 4. When the guide base plate 4 contacts the side baffle 3, the corresponding ball bearings 5 ​​rotate, reducing friction.

[0026] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
