Description

Technical Field

[0001] The utility model relates to the technical field of casting and rolling, in particular to a reciprocating roll baking device for a casting and rolling mill. Background Technique

[0002] Casting and rolling is a forming technology developed in the 1970s. The molten metal is fed into a rotating roll, and the two processes of solidification and hot rolling are completed simultaneously in the roll gap, directly becoming a semi-finished strip blank or a finished sheet. In the process of producing aluminum sheet and strip by casting and rolling method in the aluminum smelting industry, in order to prevent the aluminum sheet and strip from sticking to the casting and rolling roll, the casting and rolling roll needs to be flame-baked. By using the insufficient combustion of the flame, a thin carbon layer is formed on the surface of the casting and rolling roll, so that the aluminum sheet and strip are not easily adhered to the outer surface of the casting and rolling roll.

[0003] For example, the patent document with the publication number of CN217964681U discloses a reciprocating roll baking device for a casting and rolling mill. The roll baking device drives a reciprocating lead screw to rotate through a driving member, and then the reciprocating lead screw drives a slider to perform a reciprocating motion through rotation. At the same time, the slider drives a spray pipe to bake the casting and rolling roll back and forth. However, the lateral movement distance of the spray pipe in this roll baking device is constant. If the aluminum sheet is narrow, the width of the contact part between the casting and rolling roll and the aluminum sheet also becomes narrow. If the spray pipe moves to the part where the casting and rolling roll and the aluminum sheet do not contact, the baking of the casting and rolling roll by the spray pipe is ineffective baking, which will cause waste of resources. Content of the Utility Model

[0004] The purpose of the utility model is to provide a reciprocating roll baking device for a casting and rolling mill in order to solve the above problems.

[0005] The utility model realizes the above purpose through the following technical solutions:

[0006] A reciprocating roll baking device for a casting and rolling mill includes a casting and rolling mill body. Two baking roll mechanisms are symmetrically distributed up and down on the front side of the casting and rolling mill body. The baking roll mechanism includes a rectangular frame, which is fixed on the front side of the casting and rolling mill body. Transverse chutes are provided on both the front inner wall and the rear inner wall of the rectangular frame. Two sliders are slidably connected in the rectangular frame through the transverse chutes. The two sliders are symmetric left and right. The opposite surfaces of the two sliders are concave arc surfaces. First magnets are provided inside the front end and the rear end of the rectangular frame. Second magnets are provided inside the sliders and close to the arc surfaces. A traveling component that moves along the inner side wall of the rectangular frame and the arc surface of the slider is provided in the rectangular frame. A flame spraying component is provided on the traveling component. A guiding component for guiding the traveling component and the flame spraying component is provided on the rectangular frame. An adjusting component for adjusting the distance between the two sliders is provided on the front side of the rectangular frame.

[0007] Preferably, the traveling assembly includes a motor. A rolling wheel is fixedly connected to the output shaft of the motor. The rolling wheel is made of a magnetic material. A first guiding block is fixedly connected to the side of the motor away from the rolling wheel. The first guiding block is slidably mounted on the guiding assembly.

[0008] Preferably, the flame spraying assembly includes a rotating shaft. The rotating shaft is fixedly connected to the side of the rolling wheel away from the motor. The other end of the rotating shaft is rotatably connected to a second guiding block. A clamping bracket is fixedly connected to the other side of the second guiding block.

[0012] The beneficial effects are as follows: By using the first magnetic block in the rectangular frame and the second magnetic block in the slider, the traveling assembly can always roll along the inner side of the rectangular frame and the inner side of the slider. The traveling assembly drives the flame spraying assembly to move along an elliptical trajectory, forming a reciprocating movement, so as to realize the reciprocating baking of the casting roll.

[0024] The present utility model will be further described below in conjunction with the accompanying drawings:

[0025] As Figures 1-6As shown in the figure, a reciprocating roller baking device for a casting-rolling mill includes a casting-rolling mill body 1. There are two baking roller mechanisms symmetrically distributed up and down on the front side of the casting-rolling mill body 1. The baking roller mechanism includes a rectangular frame 2, and the rectangular frame 2 is fixed on the front side of the casting-rolling mill body 1. Transverse chutes 201 are provided on the inner walls of the front side and the rear side of the rectangular frame 2. Two sliders 3 are slidably connected in the rectangular frame 2 through the transverse chutes 201. The two sliders 3 are symmetrically arranged left and right, and the opposite surfaces of the two sliders 3 are concave arc surfaces. First magnets 202 are provided inside the front end and the rear end of the rectangular frame 2. Second magnets 301 are provided inside the sliders 3 and near the arc surfaces. A traveling component that moves along the inner side wall of the rectangular frame 2 and the arc surface of the slider 3 is provided in the rectangular frame 2. A flame spraying component is provided on the traveling component. A guiding component for guiding the traveling component and the flame spraying component is provided on the rectangular frame 2. An adjusting component for adjusting the distance between the two sliders 3 is provided on the front side of the rectangular frame 2.

[0026] The traveling component includes a motor 401. The output shaft of the motor 401 is fixedly connected with a rolling wheel 403. The rolling wheel 403 is made of magnetic material. Therefore, the rolling wheel 403 will be adsorbed by the first magnet 202 or the second magnet 301, so that the rolling wheel 403 can closely adhere to the inner side surface of the rectangular frame 2 or the arc surface of the slider 3. When the motor 401 drives the rolling wheel 403 to rotate, the rolling wheel 403 moves along the inner side surface of the rectangular frame 2 and the arc surface of the slider 3. The movement trajectory of the rolling wheel 403 is an ellipse, so that the rolling wheel 403 realizes left and right reciprocating movement. A first guiding block 402 is fixedly connected to the side of the motor 401 away from the rolling wheel 403, and the first guiding block 402 is slidably installed on the guiding component.

[0027] The flame spraying component includes a rotating shaft 501. The rotating shaft 501 is fixedly connected to the side of the rolling wheel 403 away from the motor 401. The other end of the rotating shaft 501 is rotatably connected with a second guiding block 502. A clamping bracket 503 is fixedly connected to the other side of the second guiding block 502. A flame nozzle 504 is clamped on the clamping bracket 503. The second guiding block 502 is slidably installed on the guiding component. The movement of the flame nozzle 504 is driven by the rolling of the rolling wheel 403.

[0028] The guiding assembly includes two guiding plates 601 symmetrically distributed left and right. Longitudinal through grooves 203 are formed at both ends of the rectangular frame 2. The guiding plates 601 are slidably connected in the longitudinal through grooves 203. A first guiding rod 602 and a second guiding rod 603 are fixedly connected between the two guiding plates 601. The first guiding block 402 is slidably connected to the first guiding rod 602, and the second guiding block 502 is slidably connected to the second guiding rod 603. By the guiding and limiting effect of the first guiding block 402 and the first guiding rod 602, the motor 401 itself does not rotate when the motor 401 drives the rolling wheel 403 to rotate. By the guiding and limiting effect of the second guiding block 502 and the second guiding rod 603, the flame nozzle 504 does not rotate following the rolling wheel 403, thus ensuring that the flame nozzle 504 always faces the casting roll.

[0029] Anti-slip patterns are provided on the circumferential surface of the rolling wheel 403, the front and rear inner walls of the rectangular frame 2, and the arc surface of the slider 3. The anti-slip patterns can increase friction, making the rolling process of the rolling wheel 403 smoother and more stable.

[0030] The adjusting assembly includes a bidirectional lead screw 701. The bidirectional lead screw 701 is installed on the front side of the rectangular frame 2 through a bearing seat. Two symmetrically distributed left and right translation blocks 702 are threadedly connected to the bidirectional lead screw 701. A connecting rod 703 is fixedly connected to the rear side of the translation block 702, and the connecting rod 703 is fixedly connected to the slider 3. One end of the bidirectional lead screw 701 is fixedly connected to a hand wheel 704. By rotating the bidirectional lead screw 701, the two translation blocks 702 are driven to approach or move away from each other, thereby adjusting the distance between the two sliders 3, and thus adjusting the moving range of the rolling wheel 403 in the left and right directions, so that the moving distance of the flame nozzle 504 in the left and right directions is adapted to the width of the aluminum plate. In this way, unnecessary areas on the casting roll can be avoided from being baked, reducing waste of resources.

[0031] Working principle: When in use, adjust the distance between the two sliders 3 according to the width of the aluminum plate. Rotate the bidirectional lead screw 701 through the handwheel 704. The bidirectional lead screw 701 drives the two translation blocks 702 to approach or move away from each other. The translation block 702 drives the slider 3 to move through the connecting rod 703, so as to adjust the distance between the two sliders 3 and make the distance between the two sliders 3 adapt to the width of the aluminum plate. Then, drive the rolling wheel 403 to rotate through the motor 401. Since the first magnetic block 202 and the second magnetic block 301 will generate magnetic attraction on the rolling wheel 403, the rolling wheel 403 will roll closely against the inner side wall of the rectangular frame 2 and the arc surface of the slider 3, so that the movement track of the rolling wheel 403 forms an ellipse, realizing the left and right reciprocating movement of the rolling wheel 403. The rolling wheel 403 drives the flame spray head 504 to move through the rotating shaft 501, the second guide block 502 and the clamping frame 503. The flame spray head 504 bakes the casting roll. With the cooperation of the first guide block 402 and the first guide rod 602, the motor 401 can be prevented from rotating. With the cooperation of the second guide block 502 and the second guide rod 603, the flame spray head 504 can be prevented from rotating. When the rolling wheel 403 moves to the arc surface of the slider 3, the rolling wheel 403 has a front-back movement. At this time, the guide plate 601 will move back and forth along the longitudinal through groove 203 to adapt to the movement of the rolling wheel 403.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
