[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. 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 scope of protection of the present utility model.
[0022] Hot-rolled wire rod is the current name for a metal bar processing technology, referring to the process of producing metal products through hot rolling. The production process of hot-rolled wire rod includes: pretreatment, preheating, rolling, and cooling. This process is mostly used to produce small-diameter round steel. During hot rolling, in order to roll the steel billet into steel of the target diameter, multiple rolling processes are required, which not only increases the hot rolling process space but also reduces the efficiency of hot rolling, resulting in limited practicality.
[0023] In view of this, the present invention proposes a hot-rolled wire rod mill to solve the technical problem of insufficient practicality of equipment for producing round steel using the hot-rolled wire rod process in the aforementioned background art. The present invention will be described in detail below with reference to the accompanying drawings.
[0024] A hot-rolled wire rod mill includes a first hot-rolling assembly 1, a second hot-rolling assembly 2, a wire separator 3, and a wire feeding assembly 4. The feed inlets of the two wire feeding assemblies 4 are respectively connected to the wire separator 3, and the wire outlet of the wire separator 3 is connected to the first hot-rolling assembly 1 and / or the second hot-rolling assembly 2. The first hot-rolling assembly 1 includes a first upper roll and a first lower roll, and each of the first upper roll and the first lower roll includes two parallel rolls 11 and a bearing 12 disposed between the two rolls 11. The bearing 12 is nested in a positioning block, and a driving device is driven connected to the central shaft of the two rolls 11 respectively. The second hot-rolling assembly 2 includes the first upper roll, the first lower roll, and a second left roll. Roller 21, second right roll 22, second left roll 21 and second right roll 22 are coplanar and perpendicular to the plane containing the first lower roll and the first upper roll; wherein, the wire separator 3 includes a base plate 31, a wire separator ball 32, and two sets of baffles arranged opposite to each other on the base plate 31, the two sets of baffles forming a first guide groove 33 and a second guide groove 34, the wire separator ball 32 being fixed in the middle of the end sides of the first guide groove 33 and the second guide groove 34; two wire feeding assemblies 4 are arranged side by side, the first guide groove 33 and the second guide groove 34 are respectively connected to the feed inlets of the two wire feeding assemblies 4, and the discharge outlets of the two wire feeding assemblies 4 are respectively connected to the wiring conveyor belt 5.
[0025] As described above, the hot-rolled wire rod mill provided by this utility model includes a first hot-rolling assembly 1, a second hot-rolling assembly 2, a wire separator 3, and a wire-spinning assembly 4. The first hot-rolling assembly 1 and the second hot-rolling assembly 2 have different structures and both include two hot-rolling channels, which enables the simultaneous hot rolling of two steel bars. After being hot-rolled by the first hot-rolling assembly 1 and the second hot-rolling assembly 2, the wire separator 3 guides the two round steel bars into different wire-spinning assemblies 4, so that the round steel bars fall onto two connecting conveyor belts 5 in a winding manner. This enables the processing of two round steel bars at the same time, increases the speed of hot-rolled wire rod, and thus improves the practicality of the hot-rolled wire rod mill.
[0026] Specifically, the logic for simultaneously hot-rolling two round steel bars lies in:
[0027] like Figure 1 As shown, the first hot rolling assembly 1 includes an upper first roll and a lower first roll aligned with it. Each assembly includes two parallel rolls 11, with a positioning block between them. A bearing 12 connected to the roll 11 is nested on the outer wall of the positioning block. A drive device is independently driven and connected to its central shaft to control the rolls 11 to roll the steel bars during rolling. The two rolls 11 of the upper first roll and the two rolls 11 of the lower first roll are aligned vertically to form two rolling channels with a first target shape. After the two steel bars enter, they are rolled into two steel pieces with the first target shape.
[0028] In addition, the second hot rolling assembly 2, besides the first upper roll and the first lower roll arranged vertically and horizontally similarly to those in the first hot rolling assembly 1, also includes a second left roll 21 and a second right roll 22 arranged perpendicular to the plane where the first upper roll and the first lower roll are located, i.e., two rolls 11 located to the left and right of the first upper roll, respectively. The rolling structure composed of the first upper roll, the first lower roll, the second left roll 21, and the second right roll 22 rolls the steel material into two steel pieces with a second target shape after it enters the rolling assembly.
[0029] The rolling cross-section of the first target shape and the rolling cross-section of the second target shape are complementary. For example... Figure 3As shown, the rolling cross-section of the first target shape is a flat strip with flat top and bottom surfaces and naturally formed arc-shaped left and right sides after extrusion. The rolling cross-section of the second target shape is arc-shaped on both the top and bottom surfaces and on both the left and right sides, which means that the previously extruded flat strip cross-section can be rolled into a near-circular shape. When rolling continues, the circular cross-section steel is extended and rolled into a flat strip steel again, and the flat strip steel is rolled into a circle again until the preset diameter specification of the round steel is met. Rolling stops when this is stopped, and the coiled round steel is released through the wire feeding assembly 4. That is, as mentioned above, there are multiple first hot rolling assemblies 1 and multiple second hot rolling assemblies 2, and multiple first hot rolling assemblies 1 and multiple second hot rolling assemblies 2 are alternately arranged on the hot rolling process line.
[0030] Furthermore, the outlet of the aforementioned splitter 3 is connected to the first hot-rolled assembly 1 and / or the second hot-rolled assembly 2. Here, "or" means that if the final required steel section structure may match the cross-section of the steel section rolled by the first hot-rolled assembly 1 or the second hot-rolled assembly 2, then the corresponding first hot-rolled assembly 1 or second hot-rolled assembly 2 is connected to the splitter 3. Here, "and" means that if the final required two steel sections have different cross-sections, each matching the cross-section of the steel section rolled by the first hot-rolled assembly 1 or the second hot-rolled assembly 2, then...
[0031] The structure of splitter 3 is as follows: Figure 2 As shown, the baffles form two guide grooves for the steel parts to pass through, namely the first guide groove 33 and the second guide groove 34. In addition, the dividing ball 32 is used to guide the steel parts that come out of the first hot rolling assembly 1 or the second hot rolling assembly 2 into the first guide groove 33 and the second guide groove 34 respectively.
[0032] It should be noted that the first hot-rolling assembly 1 also includes a frame, which is detachably connected to the first upper roll and the first lower roll. The first guide groove 33 and the second guide groove 34 are curved structures. The curved structure allows the steel to be pre-bent before entering the feed inlet of the wire-spinning assembly 4. Because the steel wire channel in the wire-spinning assembly 4 is curved, the pre-bending facilitates the entry of the steel wire into the steel wire channel in the wire-spinning assembly 4. In addition, this embodiment does not impose specific limitations on the driving equipment in the wire-spinning assembly 4 and the roller structure for fixing the steel wire channel; existing structures can be referred to. The aforementioned wire-connecting conveyor belt 5 is a conveying mechanism made of high-temperature resistant metal sheets. It is not only used to transport the hot-rolled round steel but also to cool the round steel during the conveying process. Air holes can be set on the conveyor belt, and a fan can be set below the conveyor belt to quickly cool the round steel. After cooling, the steel falls onto the cone on the end side of the wire-connecting conveyor belt 5, thus completing the hot-rolling of the round steel wire rod.
[0033] In some embodiments, a support plate 7 is further included between adjacent first hot-rolled assembly 1 and second hot-rolled assembly 2, the support surface of the support plate 7 including a plane or an arc surface. The support plate 7 is disposed on a mounting frame 8 and nested with a connecting block on the top surface of the mounting frame 8; a cylinder is provided inside the mounting frame 8, and the piston of the cylinder is connected to the connecting block in the vertical direction.
[0034] In this embodiment, considering that the steel is at a high temperature and its structure is unstable during hot rolling, it may be prone to bending downwards under its own weight between adjacent first hot rolling assembly 1 and second hot rolling assembly 2. Therefore, a support plate 7 is provided between them to support the transition and prevent the steel, which is easily deformed at high temperatures, from bending downwards and affecting subsequent rolling. For example, Figure 4 As shown, the supporting surface of the supporting plate 7 can be a flat surface or a curved surface. Specifically, the supporting plate 7 is mounted on the mounting frame 8 and nested with the connecting block on the top surface of the mounting frame 8. Alternatively, a cylinder can be installed inside the mounting frame 8, with the piston of the cylinder connected vertically to the connecting block to adjust the height of the supporting plate 7, further accommodating rolling processes for steel parts of different heights.
[0035] Finally, this utility model provides a hot-rolled wire rod mill, including a first hot-rolling assembly 1, a second hot-rolling assembly 2, a wire separator 3, and a wire feeding assembly 4. The feed inlets of the two wire feeding assemblies 4 are respectively connected to the wire separator 3, and the wire outlet of the wire separator 3 is connected to the first hot-rolling assembly 1 and / or the second hot-rolling assembly 2. The first hot-rolling assembly 1 includes: a first upper roll and a first lower roll, and both the first upper roll and the first lower roll include two parallel rolls 11. A driving device is respectively driven connected to the central shaft of the two rolls 11. The second hot-rolling assembly 2 includes a first upper roll... The device comprises a first lower roll, a second left roll 21, and a second right roll 22. The second left roll 21 and the second right roll 22 are coplanar and perpendicular to the plane containing the first lower roll and the first upper roll. A wire separator 3 includes a base plate 31, a wire separator ball 32, and two sets of baffles arranged opposite each other on the base plate 31 to form a first guide groove 33 and a second guide groove 34. Two wire feeding assemblies 4 are arranged side-by-side. The first guide groove 33 and the second guide groove 34 are respectively connected to the feed inlets of the two wire feeding assemblies 4, and the discharge outlets of the two wire feeding assemblies 4 are respectively connected to the connecting conveyor belt 5. This invention improves the speed of hot-rolled wire rod production and enhances the practicality of the hot-rolled wire rod mill.
[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
