Description

Technical Field

[0001] This utility model relates to the field of wire production technology, and in particular to a high-speed wire outlet guide structure. Background Technology

[0002] In the production process of wire rod used in steel rolling, it needs to be rolled on a rolling mill. The guide structure installed before and after the roll pass can help the workpiece enter and exit the roll forming accurately and stably in a predetermined direction and state.

[0003] In existing technology, guide structures are used at the inlet and outlet of all rolls. Their function is to guide the workpiece into and out of the roll pass in the required manner, ensuring that the workpiece is rolled according to predetermined deformation conditions. Due to high-temperature heating, the surface of the workpiece develops iron oxide scale and residual peeling at the beginning and end. The guide structure at the roll outlet consists of two arc-shaped structures joined together to form a circle. Peeling frequently occurs in the gap between these sections, and peeling scale and iron oxide scale easily accumulate at the bottom of the guide structure, causing scratches on the wire surface and creating serious defects, posing a significant risk to product quality.

[0004] Therefore, the inventors have provided an outlet guide structure for high-speed wires to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to propose a high-speed wire exit guide structure, which solves the technical problems in the prior art, such as peeling in the joint gap of the guide structure, and the easy accumulation of peeling and iron oxide scale at the bottom of the guide structure, which scratches the wire surface, forms serious defects, and brings great risks to product quality.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] This utility model provides a high-speed wire rod outlet guide structure, which is installed at the outlet of a rolling mill. The high-speed wire rod outlet guide structure includes a guide tube and a locking assembly for fixing the guide tube. The side wall of the inlet end of the guide tube is inclinedly provided with a flushing port that communicates with the interior of the guide tube. The flushing port is connected to a water supply device. The flushing port extends obliquely from the outer wall of the guide tube toward the inner wall of the guide tube and from the inlet end of the guide tube toward the outlet end of the guide tube, so as to supply water into the guide tube and flush the guide tube.

[0008] This high-speed wire rod outlet guide structure includes a conduit and a locking assembly for fixing the conduit. The conduit replaces the original two-piece outlet guide structure, which can prevent the accumulation of iron oxide scale and the problem of scale sticking in gaps during normal production. Moreover, the side wall of the conduit inlet end is inclinedly provided with a flushing port that communicates with the inside of the conduit. The flushing port is connected to a water supply device. The flushing port extends obliquely from the outer wall of the conduit towards the inner wall of the conduit, and from the inlet end of the conduit towards the outlet end of the conduit, to supply water into the conduit and flush the conduit, ensuring that there is no residual scale and iron oxide scale inside the conduit, eliminating potential quality problems, and reducing the labor intensity of on-site workers.

[0009] As a preferred embodiment of the aforementioned high-speed wire rod outlet guide structure, flushing ports are provided on both opposite sides of the guide tube.

[0010] Flushing inlets are provided on both sides of the conduit, which increases the flushing flow rate and the flushing coverage, thereby improving the flushing effect on the conduit.

[0011] As a preferred embodiment of the above-mentioned high-speed wire outlet guide structure, the included angle between the flushing port and the axis of the guide tube is 30°-60°.

[0012] The angle between the flushing outlet and the axis of the conduit is 30°-60°, which allows the water entering the conduit to have a component force flowing towards the outlet end of the conduit, so as to flush out the peeling skin and iron oxide scale from the conduit.

[0013] As a preferred embodiment of the above-mentioned high-speed wire outlet guide structure, the included angle between the flushing port and the axis of the guide tube is 45°.

[0014] The above setup provides good rinsing results and is also convenient for preparation.

[0015] As a preferred embodiment of the aforementioned high-speed wire outlet guide structure, the bottom of the guide tube is provided with an outlet that communicates with the interior of the guide tube.

[0016] The water outlet design prevents residual water in the conduit and avoids lowering the temperature of the head of the cable to be discharged.

[0017] As a preferred embodiment of the above-mentioned high-speed wire outlet guide structure, the bottom of the guide tube is provided with a plurality of water outlets, which are spaced apart along the length of the guide tube.

[0018] The installation of multiple outlets can improve drainage efficiency and make drainage more thorough.

[0019] As a preferred embodiment of the above-mentioned high-speed wire rod outlet guide structure, a control valve is provided on the water supply pipeline connected to the flushing port and the water supply device. The control valve is used to control the opening and closing of the flushing port and the water supply device. A detection component is provided at the outlet of the rolling mill to detect whether the wire rod to be discharged has detached from the rolling mill. The control valve is communicatively connected to the detection component.

[0020] The detection component detects whether the wire to be exported has detached from the rolling mill, so that water can be supplied into the conduit through the flushing port before the wire to be exported enters the conduit to clean the iron oxide scale inside the conduit and avoid affecting the product quality of the wire to be exported.

[0021] As a preferred embodiment of the above-mentioned high-speed wire outlet guide structure, the top, bottom, and left and right sides of the guide tube are provided with fixing blocks, and the fixing block at the bottom of the guide tube supports and fits against the base; the locking component is used to hold the fixing blocks at the top and left and right sides of the guide tube.

[0022] The fixing block at the bottom of the catheter is used to support it on the base, and the fixing blocks at the top and sides of the catheter facilitate the holding of the locking components, making it easy to fix the catheter.

[0023] As a preferred embodiment of the aforementioned high-speed wire rod outlet guide structure, the locking component includes:

[0024] A top locking member is pressed against the fixing block at the top of the conduit and is detachably connected to the base;

[0025] Side locking components are provided on both sides of the conduit. A retaining component is movably provided on the side locking component. The retaining components on both sides of the conduit can approach or move away from the fixing block on the side of the conduit to clamp or release the conduit.

[0026] The top locking member is pressed onto the fixing block at the top of the conduit and is detachably connected to the base to fix the conduit in the vertical direction; the side locking member is movably provided with abutment members, and the abutment members on both sides of the conduit can approach or move away from the fixing block on the side of the conduit to clamp or release the conduit. The side locking member can fix the conduit in the horizontal direction, thereby firmly fixing the conduit.

[0027] As a preferred embodiment of the aforementioned high-speed wire exit guide structure, the top locking member is provided with a fixing hole, through which a bolt passes and is threadedly connected to the base; the side locking member is provided with a threaded hole, and the abutment member is threadedly connected to the threaded hole.

[0028] The above configuration allows for adjustment of the position of the retaining members on the top locking member and the side locking member, so as to facilitate the fixation of different types of conduits.

[0029] The beneficial effects of this utility model are:

[0030] The high-speed wire rod outlet guide structure proposed in this utility model includes a guide tube and a locking component for fixing the guide tube. The guide tube replaces the original two-piece outlet guide structure, which can prevent the accumulation of iron oxide scale and the problem of scale sticking in gaps during normal production. Moreover, the side wall of the inlet end of the guide tube is inclinedly provided with a flushing port that communicates with the inside of the guide tube. The flushing port is connected to a water supply device and extends obliquely from the outer wall of the guide tube towards the inner wall of the guide tube, and from the inlet end of the guide tube towards the outlet end of the guide tube, so as to supply water into the guide tube and flush the guide tube, ensuring that there is no residual scale and iron oxide scale inside the guide tube, eliminating potential quality problems, and reducing the labor intensity of on-site workers.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0040] like Figures 1-4 As shown, this embodiment provides a high-speed wire rod outlet guide structure, which is installed at the outlet of the rolling mill. The high-speed wire rod outlet guide structure includes a guide tube 1 and a locking component 2 for fixing the guide tube 1. The side wall of the inlet end 11 of the guide tube 1 is inclinedly provided with a flushing port 13 that communicates with the interior of the guide tube 1. The flushing port 13 is connected to a water supply device. The flushing port 13 extends obliquely from the outer wall of the guide tube 1 toward the inner wall of the guide tube 1 and from the inlet end 11 of the guide tube 1 toward the outlet end 12 of the guide tube 1, so as to supply water into the guide tube 1 and flush the guide tube 1.

[0041] The high-speed wire rod outlet guide structure includes a conduit 1 and a locking assembly 2 for fixing the conduit 1. The conduit 1 replaces the original two-piece outlet guide structure, which can prevent the accumulation of iron oxide scale and the problem of peeling scale stuck in gaps during normal production. Moreover, the side wall of the inlet end 11 of the conduit 1 is inclinedly provided with a flushing port 13 that communicates with the interior of the conduit 1. The flushing port 13 is connected to a water supply device. The flushing port 13 extends obliquely from the outer wall of the conduit 1 toward the inner wall of the conduit 1 and from the inlet end 11 of the conduit 1 toward the outlet end 12 of the conduit 1 to supply water into the conduit 1 and flush the conduit 1, ensuring that there is no residual peeling scale and iron oxide scale inside the conduit 1, eliminating potential quality problems, and reducing the labor intensity of on-site workers.

[0042] Based on the bore diameter data of different vertical mill stands, the high-speed wire rod outlet guide structure fixes the deformed wire rod dimensions (taking the No. 6 roughing mill as an example, its bore diameter is 65.8mm, and the wire rod dimension requirement is 64.5mm). Then, a thick-walled guide tube 1 with an inner diameter of 100mm is selected as the outlet guide, leaving a 17.75mm allowance on one side of the wire rod to prevent it from rubbing against the inner wall of guide tube 1 due to unstable tension. Simultaneously, considering wear and installation length, the wall thickness of guide tube 1 is designed to be 30mm and its length 800mm.

[0043] Optionally, flushing ports 13 are provided on both sides of the conduit 1. The flushing ports 13 on both sides of the conduit 1 are symmetrically arranged, thereby increasing the flushing flow rate and flushing coverage, and improving the flushing effect on the conduit 1.

[0044] Optionally, the angle between the flushing port 13 and the axis of the conduit 1 is 30°-60°, which allows the water entering the conduit 1 to have a component force flowing towards the outlet end 12 of the conduit 1, so as to flush out the scale and iron oxide scale from the conduit 1. In this embodiment, the angle between the flushing port 13 and the axis of the conduit 1 is 45°, which provides a better flushing effect and is also easier to prepare. In other embodiments, the angle between the flushing port 13 and the axis of the conduit 1 can also be 30°, 35°, 40°, 50°, 55°, 60°, etc.

[0045] Optionally, the bottom of the conduit 1 is provided with a water outlet 14 that communicates with the interior of the conduit 1. The water outlet 14 can prevent water from remaining in the conduit 1 and prevent the temperature of the head of the wire to be discharged from dropping.

[0046] Preferably, the bottom of the conduit 1 is provided with multiple water outlets 14, which are spaced apart along the length of the conduit 1. The multiple water outlets 14 improve drainage efficiency and make drainage more thorough. The number of water outlets 14 can be set according to the length of the conduit 1; three, four, five, or more can be provided.

[0047] Optionally, a control valve (not shown in the figure) is installed on the water supply pipeline connected to the flushing port 13 and the water supply device. The control valve is used to control the opening and closing of the flushing port 13 and the water supply device. A detection component is installed at the outlet of the rolling mill to detect whether the wire to be exported has detached from the rolling mill. The control valve is communicatively connected to the detection component. By detecting whether the wire to be exported has detached from the rolling mill, water is supplied to the conduit 1 through the flushing port 13 before the wire to be exported enters the conduit 1 to clean the peeling and iron oxide scale inside the conduit 1, so as to avoid affecting the product quality of the wire to be exported.

[0048] In this embodiment, when the detection component detects that the tail of the wire to be exported has left the rolling mill, a rinsing time of 2 to 3 seconds is set to ensure that no peeling skin or iron oxide scale remains in the exit guide structure.

[0049] During normal production, the outlet guide structure is put into use and can guarantee 24-hour self-cleaning of peeling and iron oxide scale, completely eliminating the problem of peeling stuck in gaps, eliminating potential quality hazards, eliminating the need to stop the machine for cleaning, and reducing the labor intensity of on-site personnel.

[0050] Optionally, fixing blocks 15 are provided at the top, bottom, and left and right sides of the conduit 1. The fixing block 15 at the bottom of the conduit 1 supports and fits against the base 20. The locking component 2 is used to hold the fixing blocks 15 at the top and left and right sides of the conduit 1. The fixing block 15 at the bottom of the conduit 1 is used to support the base 20, and the fixing blocks 15 at the top and sides of the conduit 1 are easy to hold against by the locking component 2, making it easy to fix the conduit 1. In this embodiment, the fixing block 15 is integrally formed with the conduit 1, and the fixing block 15 fits against the circumferential surface of the conduit 1. The side of the fixing block 15 facing away from the conduit 1 is flat, which makes it easy for the fixing block 15 at the top of the conduit 1 to support the base 20, and also makes it easy for the other fixing blocks 15 to lock the conduit 1 by the locking component 2.

[0051] like Figure 1 As shown, the locking assembly 2 includes a top locking member 21 and a side locking member 22. The top locking member 21 is pressed against the fixing block 15 at the top of the conduit 1 and is detachably connected to the base 20. Side locking members 22 are provided on both sides of the conduit 1, and abutment members 221 are movably provided on the side locking members 22. The abutment members 221 on both sides of the conduit 1 can approach or move away from the fixing block 15 on the side of the conduit 1 to clamp or release the conduit 1. The top locking member 21 is pressed against the fixing block 15 at the top of the conduit 1 and is detachably connected to the base 20 to fix the conduit 1 in the vertical direction. The side locking members 22 are movably provided with abutment members 221. The abutment members 221 on both sides of the conduit 1 can approach or move away from the fixing block 15 on the side of the conduit 1 to clamp or release the conduit 1. The side locking members 22 can fix the conduit 1 in the horizontal direction, thereby firmly fixing the conduit 1.

[0052] Furthermore, the top locking member 21 is provided with a fixing hole, through which a bolt 211 passes and is threadedly connected to the base 20; the side locking member 22 is provided with a threaded hole, to which a retaining member 221 is threadedly connected. The above arrangement enables the adjustment of the position of the top locking member 21 and the retaining member 221 on the side locking member 22, so as to fix different types of conduits 1.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
