Technical Field

[0001] This utility model relates to the field of rolling mill technology, specifically to a low-manganese coiled steel processing rolling mill. Background Technology

[0002] The low-manganese coiled rebar processing mill is a piece of equipment specifically designed for producing low-manganese coiled rebar. By optimizing the chemical composition and rolling process, it reduces production costs while ensuring product quality.

[0003] Existing low-manganese coiled rebar rolling mills require cooling the rebar after rolling to control the phase transformation process and obtain ideal microstructure and properties. However, most existing mills use flowing water curtains to cool the rebar, which consumes a lot of water resources. Moreover, during cooling, the rebar needs to move rapidly during the rolling process, which prevents the water flow from contacting the rebar for a long time, reducing the cooling efficiency.

[0004] Therefore, there is an urgent need for a low-manganese coiled rebar processing mill to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a low-manganese coiled rebar processing mill to solve the problem mentioned in the background art. In existing low-manganese coiled rebar processing mills, after the coiled rebar is rolled, it is necessary to cool the rebar to control the phase transformation process of the steel and obtain ideal microstructure and properties. However, most existing mills use flowing water curtains to cool the rebar, which consumes a lot of water resources. Moreover, during cooling, because the rebar needs to move rapidly during the rolling process, the water flow cannot be in contact with the rebar for a long time, which reduces the cooling efficiency of the rebar.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a low-manganese coiled steel processing mill, comprising a mill body, a guide frame fixed to the bottom surface of the mill body, a support frame provided in the guide frame, and the support frame being movably connected to the guide frame; a liquid storage tank fixed to the top surface of the mill body, a liquid pump provided in the liquid storage tank, a replenishment pipe provided at the output end of the liquid pump, and one end of the replenishment pipe penetrating the top surface of the support frame, and a telescopic pipe provided on the surface of the replenishment pipe; further comprising a conveying assembly, which is disposed in the support frame for the recycling of coolant; and a cooling assembly, which is located between the conveying assemblies for regulating the flow rate of coolant.

[0007] Furthermore, the conveying assembly includes a drive pulley, which is axially symmetrical about the support frame. Conveying motors are fixed on both sides of the support frame, and the output end of the conveying motors is fixedly connected to the drive pulley.

[0008] Furthermore, the inner wall of the support frame is arrayed with driven pulleys, and the driven pulleys are rotatably connected to the support frame. The surfaces of the driving pulley and the driven pulley located in the same vertical plane are nested with transmission belts.

[0009] Furthermore, support rods are fixed between the driving pulleys and between the driven pulleys, and the support rods are parallel to each other. Limiting blocks are fixed on the surface of the support rods, and the limiting blocks are axially symmetrical about the support rods.

[0010] Furthermore, the cooling assembly includes a conveying frame, a liquid storage tank is provided on the top surface of the conveying frame, an adjusting shaft is provided inside the conveying frame, the adjusting shaft passes through the bottom surface of the conveying frame, and the adjusting shaft is rotatably connected to the conveying frame.

[0011] Furthermore, an adjusting motor is fixed in the conveying frame, and the output end of the adjusting motor is fixedly connected to one end of the adjusting shaft. A cooling groove is formed on the surface of the adjusting shaft, and the cooling groove penetrates the adjusting shaft.

[0012] Furthermore, the top of the conveying frame is provided with a movable sleeve, and the movable sleeve has an axisymmetric structure about the conveying frame. The movable sleeve is movably connected to the support rod, and a connecting rod is fixed between the movable sleeve and the conveying frame.

[0013] Furthermore, adjustable hydraulic rods are fixed on both sides of the guide frame, and the adjustable hydraulic rods are axially symmetrical about the guide frame. The adjustable hydraulic rods pass through the side of the guide frame, and the output end of the adjustable hydraulic rods is fixedly connected to the support frame. The bottom surface of the support frame is uniformly provided with balls, and the balls are movably connected to the bottom surface of the support frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model discloses a low-manganese coiled rebar processing mill, which includes a conveying component in the support frame. During the rebar cooling process, the support frame can collect the coolant that escapes from the device, while the conveying component can separate the cooling system in the device and then carry out independent circulation conveying. This allows the other coolants to cool down naturally while the rebar is being cooled. Moreover, during the conveying process, the liquid collected in the support frame can cool the high-temperature coolant. This design not only saves water resources but also improves the cooling efficiency of the rebar.

[0016] 2. This utility model discloses a low-manganese coiled rebar processing mill, in which cooling components are arranged in an array between the conveying components. In the cooling components, due to gravity, the bottom surface of the conveying frame remains parallel to the horizontal plane during the circulating conveying process. When the conveying frame rotates directly above the rebar, the adjusting shaft rotates in the conveying frame under the drive of the adjusting motor. Then, the coolant in the storage tank falls from the cooling tank and pours onto the surface of the rebar. This design allows the falling coolant to be adjusted in size to cool rebar of different diameters. Moreover, since the cooling tank is parallel to the rebar, the coolant can contact the rebar over a large area, improving the cooling effect of the rebar and enhancing the practicality of the device.

[0025] 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.

[0026] Please see Figures 1-7 This utility model provides a low-manganese coiled steel processing mill, including a mill body 4, a guide frame 3 fixed to the bottom surface of the mill body 4, a support frame 9 provided in the guide frame 3, and the support frame 9 being movably connected to the guide frame 3, a liquid storage tank 5 fixed to the top surface of the mill body 4, a liquid pump 6 provided in the liquid storage tank 5, a replenishment pipe 7 provided at the output end of the liquid pump 6, and one end of the replenishment pipe 7 penetrating the top surface of the support frame 9, and a telescopic pipe 8 provided on the surface of the replenishment pipe 7; it also includes a conveying assembly 1, which is set in the support frame 9 for the recycling of coolant; a cooling assembly 2, which is located between the conveying assembly 1 for the flow rate adjustment of coolant; adjusting hydraulic rods 11 fixed on both sides of the guide frame 3, and the adjusting hydraulic rods 11 having an axisymmetric structure about the guide frame 3, and penetrating the side of the guide frame 3, and the output end of the adjusting hydraulic rods 11 being fixedly connected to the support frame 9; and ball bearings 10 evenly provided on the bottom surface of the support frame 9, and the ball bearings 10 being movably connected to the bottom surface of the support frame 9.

[0027] Specifically, during operation of the low-manganese coiled rebar mill, the main body 4 of the mill guides the rolled rebar to the support frame 9. Then, the conveying component 1 circulates the cooling component 2 within the support frame 9. When one of the cooling components 2 moves above the rebar, the coolant in the cooling component 2 is poured downwards onto the surface of the rebar. Simultaneously, the symmetrical cooling component 2 catches the coolant after contact with the rebar. The coolant in the other cooling components 2 cools naturally during the conveying process, while the coolant in the support frame 9 cools the cooling components 2. The function of the liquid storage tank 5 is to replenish the coolant lost due to evaporation in the support frame 9 through the liquid replenishment pipe 7. The function of the adjusting hydraulic rods 11 on both sides of the guide frame 3 is to ensure that the central axis of the rebar coincides with the central axis of the support frame 9. The ball bearings 10 facilitate the movement of the support frame 9.

[0028] The conveying assembly 1 includes a drive pulley 103, which is axially symmetrical about the support frame 9. Conveying motors 101 are fixed on both sides of the support frame 9, and the output end of the conveying motors 101 is fixedly connected to the drive pulley 103. Driven pulleys 104 are arrayed on the inner wall of the support frame 9, and the driven pulleys 104 are rotatably connected to the support frame 9. A transmission belt 105 is nested on the surface of the drive pulley 103 and the driven pulleys 104 located in the same vertical plane. Support rods 102 are fixed between the drive pulleys 103 and between the driven pulleys 104, and the support rods 102 are parallel to each other. Limiting blocks 106 are fixed on the surface of the support rods 102, and the limiting blocks 106 are axially symmetrical about the support rods 102.

[0029] Specifically, the support frame 9 can collect the coolant that escapes from the device during the cooling process of the rebar, while the conveying component 1 can separate the cooling system in the device and then carry out independent circulation and conveying, so that while the rebar is being cooled, other coolants can be cooled naturally. Moreover, during the conveying process, the liquid collected in the support frame 9 can cool the high-temperature coolant. This design not only saves water resources, but also improves the cooling efficiency of the rebar.

[0030] The cooling assembly 2 includes a conveying frame 204, a liquid storage tank 202 on the top surface of the conveying frame 204, an adjusting shaft 203 inside the conveying frame 204, the adjusting shaft 203 passing through the bottom surface of the conveying frame 204 and rotatably connected to the conveying frame 204, an adjusting motor 201 fixed in the conveying frame 204, the output end of the adjusting motor 201 fixedly connected to one end of the adjusting shaft 203, a cooling groove 205 on the surface of the adjusting shaft 203, the cooling groove 205 passing through the adjusting shaft 203, a movable sleeve 207 on the top of the conveying frame 204, the movable sleeve 207 having an axisymmetric structure about the conveying frame 204, and the movable sleeve 207 being movably connected to the support rod 102, and a connecting rod 206 fixed between the movable sleeve 207 and the conveying frame 204.

[0031] Specifically, in the cooling assembly 2, due to gravity, the bottom surface of the conveying frame 204 remains parallel to the horizontal plane during the circulating conveying process. When the conveying frame 204 rotates directly above the rebar, the adjusting shaft 203 rotates within the conveying frame 204 under the drive of the adjusting motor 201. Then, the coolant in the storage tank 202 falls from the cooling tank 205 and pours onto the surface of the rebar. This design allows the falling coolant to be adjusted in size to cool rebars of different diameters. Furthermore, since the cooling tank 205 is parallel to the rebar, the coolant can contact the rebar over a large area, improving the cooling effect and enhancing the practicality of the device.

[0032] Working principle: In the conveying assembly 1, driven by the conveying motor 101, the driving pulley 103 drives all the driven pulleys 104 to rotate through the transmission belt 105. Then, the support rod 102 rotates cyclically in the support frame 9. In the cooling assembly 2, due to gravity, the bottom surface of the conveying frame 204 remains parallel to the horizontal plane during the cyclic conveying process. When the conveying frame 204 rotates directly above the rebar, driven by the adjusting motor 201, the adjusting shaft 203 rotates in the conveying frame 204. Then, the coolant in the storage tank 202 falls from the cooling tank 205 and pours onto the surface of the rebar. This design allows the falling coolant to be adjusted in size to cool rebars of different diameters. Moreover, since the cooling tank 205 is parallel to the rebar, the coolant can contact the rebar over a large area.

[0033] When the low-manganese coiled rebar mill is working, the main body 4 of the mill guides the rolled rebar to the support frame 9. Then, the conveying component 1 circulates the cooling component 2 within the support frame 9. When one of the cooling components 2 moves above the rebar, the coolant in the cooling component 2 is poured downwards onto the surface of the rebar. At the same time, the symmetrical cooling component 2 catches the coolant after contact with the rebar. The coolant in the other cooling components 2 cools naturally during the conveying process. The coolant in the support frame 9 can cool the cooling components 2. The function of the liquid storage tank 5 is to replenish the coolant lost due to evaporation in the support frame 9 through the liquid replenishment pipe 7. The function of the adjusting hydraulic rods 11 on both sides of the guide frame 3 is to make the central axis of the rebar coincide with the central axis of the support frame 9. The ball bearings 10 facilitate the movement of the support frame 9.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
