Description
TECHNICAL FIELD
[0001] The utility model relates to hot rolling technical field, concretely is a kind of φ12.3mm wire rod finished product pass. BACKGROUND
[0002] Wire rod products have wide applications in industrial manufacturing and daily life, with various specifications and sizes to meet the needs of different fields. Common wire rod product specifications include diameters ranging from 5.0mm, 5.5mm, 6.5mm, 7.0mm, 7.5mm, up to 12.0mm, 12.5mm and 13.0mm. These specifications of wire rod products are usually processed and formed through specific passes to ensure their dimensional accuracy and surface quality.
[0003] However, in existing wire rod processing technology, there is a significant problem: although wire rod products have various specifications and sizes, not all possible sizes have corresponding dedicated finished product passes. In particular, for φ12.3mm wire rod products, there is no dedicated finished product pass available on the market. Due to the lack of a dedicated pass, manufacturers often face many challenges when producing φ12.3mm wire rod. They may need to use a pass of similar size for processing, which not only affects the dimensional accuracy of the wire rod, but also may adversely affect its surface quality and overall performance. In addition, the lack of a dedicated pass may also lead to low production efficiency and increased costs. Therefore, we propose a φ12.3mm wire rod finished product pass to solve the above problems.

[0006] (II) Technical solution

[0008] A kind of φ12.3mm wire finished product pass, including base circle 1, the base circle 1 has 6.22mm radius, as the starting shape of pass, the base circle 1 is expanded outward to form outer expansion angle 2 region, the angle of outer expansion angle 2 is 22 °, outer diameter 3 is equipped on the extension of base circle 1, the radius of outer diameter 3 is 12.44mm, and it is smoothly transitioned with outer expansion angle 2 region, the outlet end of base circle 1 is equipped with roll gap 4, the width of roll gap 4 is 1.14mm, for accurately control the outflow gap of wire, the entrance of base circle 1 is equipped with notch 5, the width of notch 5 is 12.66mm, for guiding wire to enter pass smoothly.
[0009] Further, the transition between the outer expansion angle 2 region and the base circle 1 is gradual to reduce stress concentration of the wire during rolling.
[0010] Further, the end edge of the outer diameter 3 is chamfered to reduce friction and wear of the wire during rolling.
[0011] Further, the shape and size of the notch 5 are optimized to reduce jamming and deformation of the wire during introduction.

[0013] (Three) beneficial effects
[0014] Compared with the prior art, the φ12.3mm wire finished product pass provided by the utility model has the following beneficial effects:
[0015] In the utility model, the wire first enters the pass through the notch, the width of the notch matches the cross-sectional size of the wire to ensure that the wire is accurately and stably positioned at the starting position of the pass. Once the wire enters the pass, it starts to gradually expand along the outer expansion angle. The outer expansion angle is designed to gradually and uniformly deform the wire during rolling to avoid stress concentration and possible material rupture. As the wire continues to pass through the pass, it eventually reaches the outer diameter, which defines the final outer diameter of the wire after rolling. The smooth transition and polishing of the outer diameter region help to reduce scratches on the surface of the wire and improve the smoothness of the product. At the outlet position of the pass, the roll gap region ensures that the wire passes through with the required gap. This design helps to maintain the diameter accuracy of the wire, improves the quality and consistency of the product, and helps to improve production efficiency and reduce costs.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Example
[0020] like Figure 1 As shown in the figure, an embodiment of this utility model provides a finished die for a φ12.3mm wire, including a base circle 1 with a radius of 6.22mm, serving as the initial shape of the die. The base circle 1 extends outward to form an expansion angle 2 region with an angle of 22°. An outer diameter 3 with a radius of 12.44mm is provided on the extended portion of the base circle 1, and it smoothly transitions with the expansion angle 2 region. A roller gap 4 with a width of 1.14mm is provided at the exit end of the base circle 1 to precisely control the wire's outflow gap. A groove 5 with a width of 12.66mm is provided at the entrance of the base circle 1 to guide the wire smoothly into the die. The wire first enters the die through the groove 5. The width of the groove 5 matches the cross-sectional dimensions of the wire, ensuring that the wire can be accurately and stably positioned at the starting position of the die. Once the wire enters the die, it begins to gradually expand along the outer expansion angle 2. This angle 2 is designed to allow the wire to deform gradually and evenly during rolling, avoiding stress concentration and potential material fracture. As the wire continues through the die, it eventually reaches the outer diameter 3, a region with a radius of 12.44 mm that defines the final outer diameter of the rolled wire. The smooth transition and polishing of the outer diameter 3 region help reduce scratches on the wire surface and improve the product's finish. At the die exit, the roll gap 4 region, with a precisely controlled width of 1.14 mm, ensures the wire passes through with the required clearance. This design helps maintain the wire's diameter accuracy and prevents excessive deformation or jamming during rolling. The entire rolling process is continuous; the wire passes through the die at a controlled speed while being subjected to continuous pressure from the rolls. This continuous production mode helps improve production efficiency and product consistency, achieving precise control, gradual expansion, and final shaping of the wire during rolling. This design not only improves product quality and consistency but also contributes to increased production efficiency and reduced costs.
[0021] In some embodiments, the transition between the outer expansion angle 2 region and the base circle 1 is gradual to reduce stress concentration in the wire during the rolling process.
[0022] In some embodiments, the end edge of the outer caliber 3 is chamfered to reduce friction and wear of the wire during rolling.
[0023] In some embodiments, the shape and size of the notch 5 are optimized to reduce jamming and deformation of the wire during the lead-in process. The optimized design of the notch 5 ensures smooth entry of the wire into the rolling mill, reducing downtime and production interruptions due to jamming. This helps to improve overall production efficiency and smooth production flow.
[0024] In some embodiments, the width of the roll gap 4 is adjustable to accommodate different specifications or material requirements for wire production. The adjustable roll gap 4 allows the same set of rolling mill equipment to produce multiple different specifications of wire without frequent replacement of rollers or adjustment of equipment, thereby improving production flexibility and adaptability.
[0025] In operation or structural principle, the wire first enters the pass through the notch 5, the width of the notch 5 matches the cross-sectional size of the wire, ensuring that the wire can be accurately and stably positioned at the starting position of the pass. Once the wire enters the pass, it begins to gradually expand along the outer expansion angle 2, which is designed to gradually and uniformly deform the wire during rolling, avoiding stress concentration and possible material rupture. As the wire continues to pass through the pass, it eventually reaches the outer caliber 3, which has a radius of 12.44 mm, defining the final outer diameter of the rolled wire. The smooth transition and polishing of the outer caliber 3 area help to reduce scratches on the surface of the wire and improve the finish of the product. At the exit position of the pass, the roll gap 4 area is controlled to a width of 1.14 mm to ensure that the wire passes through with the required gap. This design helps to maintain the diameter accuracy of the wire and prevent excessive deformation or jamming during rolling. The entire rolling process is continuous, with the wire passing through the pass at a certain speed while being subjected to continuous pressure from the rollers. This continuous production mode helps to improve production efficiency and product consistency, achieving accurate control, gradual expansion, and final shaping of the wire during rolling. This design not only improves product quality and consistency, but also helps to improve production efficiency and reduce costs.
[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some technical features.
