Description

Technical Field

[0001] The utility model relates to the field of aluminum ingot production, in particular to a device for preventing billet ingots from being bent by rolling shearing. Background Art

[0002] The aluminum ingot casting process includes: smelting and standing → online refining → filtering → casting → continuous casting → shearing → cooling → stacking → weighing → packaging. After the hot aluminum billet comes out of the crystallizer, it is first straightened by a straightening machine, and then it is marked by a marking roller and enters a rolling shearing machine, and is cut under the action of a rolling shearing machine. However, the billet after rolling shearing will bend and warp to varying degrees due to the shear force. The existing technology mainly uses manual force to pry and press to assist in flattening the billet, which is not only time-consuming and labor-intensive, but also often workers rely on experience to judge whether the billet flattening operation is completed. The flattening quality is difficult to guarantee, and this method often leads to stacking problems due to the inability to keep up with the speed of the production line.

[0003] In addition, during the casting process of aluminum ingots, it is necessary to detect the temperature of the billet in real time to ensure the casting quality, which also includes the above-mentioned flattening process. Because the hardness of the billet under different temperature conditions is different, the required flattening pressure will also be different. However, the temperature measurement of the billet in the prior art is mainly continuous contact temperature measurement. For example, the patent CN215984924U discloses a billet contact continuous temperature measurement device, which has several temperature sensors in the continuous casting roller. The temperature sensor is connected to the electric slip ring and outputs the temperature signal through the electric slip ring, and the continuous casting roller contacts the billet to realize continuous contact temperature measurement. However, during the above-mentioned billet flattening process, since it is necessary to apply force to the billet to flatten it, it is difficult to measure the temperature of the billet using the above-mentioned continuous contact temperature measurement method.

DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] like Figures 1-2 As shown, the utility model includes a flattening mechanism 1 and an infrared temperature sensor 7 arranged above the transmission line 4, wherein the flattening mechanism 1 includes a pressure roller 102 and two pressure regulating devices 101, and the lower end of the pressure regulating device 101 is connected to the corresponding end of the pressure roller 102, and the aluminum billet 6 that has completed rolling shearing is driven through the transmission line 4 to enter under the flattening mechanism 1 and completes the flattening operation through the pressure roller 102. At the same time, the infrared temperature sensor 7 detects the temperature of the aluminum billet 6 in real time and transmits the detection value to the equipment control system. The equipment control system controls the flattening pressure value applied by the pressure regulating device 101 according to the temperature data of the infrared temperature sensor 7, thereby achieving effective flattening of the aluminum billet 6.

[0025] The infrared temperature sensor 7 is a commercially available product. In this embodiment, the infrared temperature sensor 7 can be purchased from Suzhou Simai Instrument Technology Co., Ltd. Before the operation of the utility model, the required flattening pressure of the aluminum billet 6 under different temperature conditions will be determined through experiments. Then, when the utility model is officially operated, as the aluminum billet 6 moves on the transmission line 4, the infrared temperature sensor 7 will continuously measure the temperature of the surface of the aluminum billet 6 and transmit it to the operation panel of the equipment control system to form a continuous temperature curve, and finally achieve the purpose of controlling the billet temperature during the flattening process of the aluminum billet 6. At the same time, the equipment control system determines the corresponding flattening pressure value obtained through the previous test according to the detected temperature conditions, and then the equipment control system controls the pressure regulating device 101 to adjust the pressure to the flattening pressure to achieve effective flattening of the aluminum billet 6.

[0026] like Figures 1-2 As shown, in this embodiment, the transmission line 4 is provided with a bracket 2, and the flattening mechanism 1 and the infrared temperature sensor 7 are both provided on the bracket 2, wherein Figure 2 As shown, bracket connection seats 401 are provided on both sides of the frame of the transmission line 4, and the lower ends of the bracket 2 on both sides are connected to the bracket connection seats 401 on the corresponding side by connecting bolts and connecting nuts, respectively. The bracket connection seats 401 are provided with connecting through holes with a diameter larger than the connecting bolts, and the connecting bolts are threadedly connected with the connecting nuts after passing through the connecting through holes, so that the lower end of the bracket 2 is fixedly connected to the bracket connection seat 401 through the clamping action of the nut of the connecting bolt and the connecting nut. When the utility model is working, the bracket 2 can be flipped to any side of the transmission line 4 according to actual needs to meet production needs. At this time, it is only necessary to remove the connecting bolts and connecting nuts on one side of the bracket connection seat 401, and loosen the connecting bolts and connecting nuts on the other side of the bracket connection seat 401, and the bracket 2 can be flipped to one side of the transmission line 4 with the loosened connecting bolts as the rotation axis. When the aluminum billet 6 needs to be flattened, the bracket 2 is restored to its original position.

[0027] The bracket 2 can be fixed on the frame of the transmission line 4, or can be adjustably arranged on the frame of the transmission line 4.

[0028] In one embodiment of the utility model, a plurality of bracket connecting seats 401 can be provided on the frames on both sides of the transmission line 4 according to actual needs, and the lower sides of both ends of the bracket 2 are respectively fixed on the corresponding bracket connecting seats 401, so that the position of the bracket 2 can be adjusted according to actual needs, such as adjusting the position of the bracket 2 according to different shear lengths of the aluminum billet 6, and then adjusting the positions of the pressure roller 102 and the infrared temperature sensor 7, which improves the flexibility of use of the utility model.

[0029] In another embodiment of the utility model, the frame of the transmission line 4 is provided with a plurality of groups of adjustment screw holes, and the bracket connection seat 401 is installed on a corresponding group of adjustment screw holes through a bolt and nut assembly. This embodiment can also meet the position adjustment needs of the bracket 2. When adjusting, the bracket 2 is first disassembled, and then the bracket connection seat 401 is installed on a suitable group of adjustment screw holes, and then the bracket 2 is reinstalled. The advantage of this embodiment is that it is convenient to carry out technical transformation of existing equipment. When transforming, it is only necessary to open threaded holes at the corresponding positions of the frame of the transmission line 4, and it is not necessary to weld and fix multiple bracket connection seats 401, which has little impact on the existing equipment structure.

[0030] The transmission line 4 is a well-known technology in the art and a commercially available product, for example, a transmission line of Dalian Jialin brand can be used.

[0031] like Figures 1-2 As shown, in this embodiment, the pressure regulating device 101 in the flattening mechanism 1 is a gas spring, which realizes pressure regulation by supplying air through the air pipe 103 at the rear end. This is a well-known technology in the art, for example, see patents such as CN216691979U and CN207161594U.

[0032] like Figures 1-2 As shown, in this embodiment, a connecting plate 104 is provided at the lower end of the pressure regulating device 101, roller shafts are provided at both ends of the pressing roller 102, and the connecting plate 104 is connected to the roller shafts at the corresponding ends of the pressing roller 102 through a fastening nut 105. The pressing roller 102 can flatten the aluminum billet 6 to ensure its straightness, and can also eliminate the peeling, sharp and uneven defects of part of the surface of the aluminum billet 6.

[0033] like Figures 1-2 As shown, in this embodiment, a photoelectric sensor 5 is provided on one side of the bracket 2, and a reflector 3 is provided on the other side. The photoelectric sensor 5 and the reflector 3 are used to detect the length of the aluminum billet 6 after rolling shearing in real time. Specifically, when the aluminum billet 6 does not enter the detection range of the photoelectric sensor 5, the reflector 3 can receive the signal sent by the photoelectric sensor 5. When the head end of the aluminum billet 6 enters the detection range of the photoelectric sensor 5, the reflector 3 is blocked by the aluminum billet 6 and the signal reception is interrupted. At this time, the reflector 3 starts to transmit the signal to the equipment control system, and the equipment control system starts timing and converts and determines the length value of the aluminum billet 6 according to the casting speed of the current production line, thereby maximally avoiding the geometric material loss caused by the different lengths of the aluminum billet 6, and further improving the controllability of the product production process. The photoelectric sensor 5 and the reflector 3 are both commercially available products, such as Keyence brand products.

[0034] The working principle of the utility model is:

[0035] In the prior art, after the aluminum billet 6 passes through rolling shearing, at least one operator is required to flatten the sheared billet. This is not only time-consuming and labor-intensive, but also often results in material stacking problems due to reasons such as operator errors that cannot keep up with the speed of the production line. At the same time, manual flattening mainly relies on the workers' experience and judgment, and the flattening stability and quality of the aluminum billet 6 need to be improved.

[0036] When the utility model is working, the aluminum billet 6 that has completed rolling shearing is driven by the transmission line 4 to enter the flattening mechanism 1 and automatically completes the flattening operation through the pressure roller 102, which can meet the production speed requirements of the production line. At the same time, the infrared temperature sensor 7 detects the temperature of the aluminum billet 6 in real time and transmits the detection value to the equipment control system. The equipment control system controls the flattening pressure value applied by the pressure regulating device 101 according to the temperature data of the infrared temperature sensor 7, thereby realizing effective flattening of the aluminum billet 6 and ensuring the stability and quality of the flattening of the aluminum billet 6.

[0037] The flattening mechanism 1 and the infrared temperature sensor 7 are both arranged on the bracket 2 on the transmission line 4, and bracket connecting seats 401 are provided on both sides of the frame of the transmission line 4, and the lower ends of the two sides of the bracket 2 are respectively connected to the bracket connecting seats 401 on the corresponding side by connecting bolts and connecting nuts. In this way, the utility model can flip the bracket 2 to any side of the transmission line 4 according to actual needs to meet production needs. When flipping, it is only necessary to remove the connecting bolts and connecting nuts on the bracket connecting seat 401 on one side, and loosen the connecting bolts and connecting nuts on the bracket connecting seat 401 on the other side. Then, the bracket 2 can be flipped to one side of the transmission line 4 with the loosened connecting bolts as the rotating axis, and when the aluminum billet 6 needs to be flattened, the bracket 2 is restored to its original position.

[0038] In addition, the bracket 2 can be fixed on the transmission line 4, and can also be adjustably arranged on the transmission line 4, so as to meet the flattening needs of aluminum billets 6 with different shear lengths.
