[0040] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some well-known technical features in the art are not described.

[0041] It should be understood that the present invention can be implemented in different forms and should not be construed as limited to the embodiments presented here. On the contrary, providing these embodiments will make the disclosure thorough and complete, and will fully convey the scope of the present invention to those skilled in the art. In the drawings, the same reference numerals represent the same components throughout. Terms such as "upper", "lower", "left", "right", "middle", and "one" cited in this specification are only for the convenience of description and are not used to limit the scope in which the present invention can be implemented. The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope in which the present invention can be implemented.

[0042] The specific structure of a hot-rolled steel plate double-stream forming guide device in the present invention is described in combination with reference to Figures 1 to 9, the device includes an outer frame 100, an upper guide installation platform 210, a lower guide installation platform 220, an upper roll system unit and a lower roll system unit. The upper guide installation platform 210 is arranged on the outer frame 100 so as to be adjustable up and down along the outer frame 100 and locked at a designated position. Two upper roll system units are arranged side by side. Each upper roll system unit includes a first left roll system 510 and a first right roll system 520. The first left roll system 510 and the first right roll system 520 are both arranged on the upper guide installation platform 210 so as to be adjustable left and right. The lower guide installation platform 220 is arranged on the outer frame 100 so as to be adjustable up and down along the outer frame and locked at a designated position. Two lower roll system units are correspondingly arranged with the two upper roll system units. Each lower roll system unit includes a second left roll system 610 and a second right roll system 620. The second left roll system 610 and the second right roll system 620 are both arranged on the lower guide installation platform 220 so as to be adjustable left and right. The two lower roll system units and the corresponding two upper roll system units form a double-flow guide structure. The first left roll system 510, the first right roll system 520, the second left roll system 610 and the second right roll system 620 of each flow guide structure form a threading channel for the hot steel plate. The threading channel is located between the upper guide installation platform 210 and the lower guide installation platform 220. Among them, the up-down, left-right, and front-back positional relationships can Figure 1 be understood with reference.

[0043] In the specific implementation process, both the upper guide installation platform 210 and the lower guide installation platform 220 are slidably connected to the outer frame 100 up and down. The upper guide installation platform 210 is directly above the lower guide installation platform 220. Figure 1 The sliding directions of the upper guide installation platform 210 and the lower guide installation platform 220 in the middle are in the vertical direction. The two upper roll system units and the two lower roll system units are both located between the upper guide installation platform 210 and the lower guide installation platform 220. Furthermore, a double-flow guide structure is formed between the upper guide installation platform 210 and the lower guide installation platform 220, that is, the two formed threading channels are both located between the upper guide installation platform 210 and the lower guide installation platform 220.

[0044] In this embodiment, the first left roll system 510 and the first right roll system 520 are inclined roll systems, and the second left roll system 610 and the second right roll system 620 are horizontal roll systems, so that both sides of the threading channel form a downwardly inclined shape. In the actual implementation process, according to the needs of the steel plate shape, horizontal or multi-structured roll systems can be adopted to make the threading channel form the shape of the required steel plate cross-section. Among them, the outer frame 100 is as Figure 6As shown, it is a rectangular outer frame 100, which has four columns 110. The front side and the rear side of the upper guide installation platform 210 and the lower guide installation platform 220 are respectively in tight contact and slide with two columns 110.

[0045] During use, the upper guide installation platform 210 and the lower guide installation platform 220 can be vertically slid, and the two double-flow guide structures can be adjusted up and down correspondingly according to the needs of hot-rolled steel plate forming, that is, the thickness and position of the two strip-passing channels are adjusted. Then, the positions of the first left roll system 510, the first right roll system 520, the second left roll system 610, and the second right roll system 620 in the horizontal direction are adjusted left and right, and the widths of the two strip-passing channels and the positions of the two sides inclined downward are respectively adjusted. Then, the two hot-rolled steel plates are simultaneously passed through the two strip-passing channels for forming guide. When the hot-rolled steel plates pass through the strip-passing channels, the upper roll system unit and the lower roll system unit play a role in forming and guiding the hot-rolled steel plates. After passing through the strip-passing channels, steel plates of the required size can be obtained. The two hot-rolled steel plates are formed at one time, realizing the forming and guiding work of the hot-rolled steel plates, and doubling and increasing the efficiency of steel plate forming.

[0046] In some embodiments, a pressing-up adjusting unit 300 and a pressing-down adjusting unit 400 are provided on the outer frame 100. The pressing-up adjusting unit 300 is used to adjust and lock the upper guide installation platform 210 up and down, and the pressing-down adjusting unit 400 is used to adjust and lock the lower guide installation platform 220 up and down.

[0047] For example, Figure 1 、 Figure 8 、 Figure 9 In [specific examples], the pressing-up adjusting unit 300 is installed above the outer frame 100 and is used to adjust the position of the upper guide installation platform 210, and the pressing-down adjusting unit 400 is installed at the lower end of the outer frame 100 and is used to adjust the position of the lower guide installation platform 220.

[0048] In some embodiments, a driving mechanism is provided on the outer frame 100 for driving the upper guide installation platform 210 and / or the lower guide installation platform 220 to pitch and adjust in the front-rear direction.

[0049] In the specific implementation process, a driving mechanism is designed to make the upper guide installation platform 210 and the lower guide installation platform 220 pitch and adjust in the front-rear direction. This driving mechanism can be independent of the pressing-up adjusting unit 300 and the pressing-down adjusting unit 400, so that the pitch adjustment of the upper guide installation platform 210 and the lower guide installation platform 220 can be controlled separately, which is more convenient for operation.

[0050] In some embodiments, the upward pressing adjustment unit 300 includes a first lifting adjustment component 310 acting on the rear part of the upper guide guard mounting platform 210, and a second lifting adjustment component 320 acting on the front part of the upper guide guard mounting platform 210. The adjustment heights of the first lifting adjustment component 310 and the second lifting adjustment component 320 are the same or different; the downward pressing adjustment unit 400 includes a third lifting adjustment component 410 acting on the rear part of the lower guide guard mounting platform 220, and a fourth lifting adjustment component 420 acting on the front part of the lower guide guard mounting platform 220. The adjustment heights of the third lifting adjustment component 410 and the fourth lifting adjustment component 420 are the same or different.

[0051] In the specific implementation process, Figure 1 in, the first lifting adjustment component 310 and the second lifting adjustment component 320 can respectively adjust the height positions of the rear part and the front part of the upper guide guard mounting platform 210, so that the rear part and the front part of the upper guide guard mounting platform 210 are at the same height or different heights. When the rear part and the front part of the upper guide guard mounting platform 210 are at different heights, the upper guide guard mounting platform 210 is in a tilted state of pitching forward or backward in the front-rear direction. The third lifting adjustment component 410 and the fourth lifting adjustment component 420 can respectively adjust the positions of the rear part and the front part of the lower guide guard mounting platform 220, and can make the rear part and the front part of the lower guide guard mounting platform 220 be at the same height or different heights. When the rear part and the front part of the lower guide guard mounting platform 220 are at different heights, the lower guide guard mounting platform 220 is in a tilted state of pitching forward or backward in the front-rear direction. The front-rear angle of the threading channel can be adjusted through the pitching states of the upper guide guard mounting platform 210 and the lower guide guard mounting platform 220, so that the formed hot-rolled steel plate meets the required angle requirements.

[0052] In some embodiments, both the first lifting adjustment component 310 and the second lifting adjustment component 320 include an upward pressing power member 331 and an upward pressing lifting member 332. The upward pressing lifting member 332 is connected to the upper guide guard mounting platform 210, and the upward pressing power member 331 adjusts the upper guide guard mounting platform 210 up and down through the upward pressing lifting member 332; the third lifting adjustment component 410 and the fourth lifting adjustment component 420 include a downward pressing power member 431 and a downward pressing lifting member 432. The downward pressing lifting member 432 is connected to the lower guide guard mounting platform 220, and the downward pressing power member 431 adjusts the lower guide guard mounting platform 220 up and down through the downward pressing lifting member 432.

[0053] For example, Figure 1 、 Figure 8 、 Figure 9As shown, the upward pressing power member 331 and the downward pressing power member 431 can be selected as motors, and the upward pressing lifting member 332 and the downward pressing lifting member 432 can be selected as screw jacks. The motor and the screw jack are connected by a transmission rod. By rotating the motor, driving the transmission rod, and driving the screw jack to move up and down, the position adjustment of the upper guide installation platform 210 and the lower guide installation platform 220 is realized. In the specific implementation process, the first lifting adjustment assembly 310, the second lifting adjustment assembly 320, the third lifting adjustment assembly 410, and the fourth lifting adjustment assembly 420 are adjusted separately. During adjustment, only the motor needs to be powered on and rotated, driving the transmission rod to rotate, acting on the screw jack, and adjusting the height position of the front side or the rear side of the upper guide installation platform 210 or the lower guide installation platform 220.

[0054] In some embodiments, a pressing upper ear plate 333 is rotatably connected to the lower end of the upward pressing lifting member 332, and the pressing upper ear plate 333 is fixedly connected to the upper guide installation platform 210; a pressing lower ear plate 433 is rotatably connected to the lower end of the downward pressing lifting member 432, and the pressing lower ear plate 433 is fixedly connected to the lower guide installation platform 220.

[0055] In the specific implementation process, as Figure 1 、 Figure 8 、 Figure 9 shown, the upward pressing lifting member 332 is connected to the upper guide installation platform 210 through the pressing upper ear plate 333, which can make the connection between the upward pressing lifting member 332 and the upper guide installation platform 210 firm, and the upward pressing lifting member 332 can rotate along the upper guide installation platform 210, which is more conducive to the adjustment of the upper guide installation platform 210 by the upward pressing lifting member 332; similarly, the downward pressing lifting member 432 is connected to the lower guide installation platform 220 through the pressing lower ear plate 433, which can make the connection between the downward pressing lifting member 432 and the lower guide installation platform 220 firm, and the downward pressing lifting member 432 can rotate along the lower guide installation platform 220, which is more conducive to the adjustment of the lower guide installation platform 220 by the downward pressing lifting member 432.

[0056] In some embodiments, first sliders 120 are provided on both the front and rear sides of the upper guide mounting platform 210. Each of the first sliders 120 is slidably mounted on a column 110 of the outer frame 100. The front and rear sides of the upper guide mounting platform 210 are respectively in arc surface fit with the corresponding first sliders 120 and can relatively rotate in the vertical direction with respect to the first sliders 120. Second sliders 130 are provided on both the front and rear sides of the lower guide mounting platform 220. Each of the second sliders 130 is slidably mounted on a column 110 of the outer frame 100. The front and rear sides of the lower guide mounting platform 220 are respectively in arc surface fit with the corresponding second sliders 130 and can relatively rotate in the vertical direction with respect to the second sliders 130.

[0057] During the actual implementation process, as Figure 6 shown, on the columns 110 on the rear side of the outer frame 100 and the columns 110 on the front side of the outer frame 100, the side surface of the column 110 is a slide plate 111. Locking plates 112 are provided on both sides of the slide plate 111. The slide plate 111 and the locking plates 112 form a structure similar to a chute. Both the first sliders 120 and the second sliders 130 are slidably connected in the chute. The front and rear sides of the upper guide mounting platform 210 are respectively in arc surface fit with the corresponding first sliders 120 and can relatively rotate in the vertical direction with respect to the first sliders 120, so that the upper guide mounting platform 210 is slidably connected to the outer frame 100. When the front and rear sides of the upper guide mounting platform 210 are respectively adjusted in height, after the upper guide mounting platform 210 is in a pitching state, its front and rear sides can still maintain a slidable connection with the outer frame 100 in the vertical direction. The front and rear sides of the lower guide mounting platform 220 are respectively in arc surface fit with the corresponding second sliders 130 and can relatively rotate in the vertical direction with respect to the second sliders 130, so that when the front and rear sides of the lower guide mounting platform 220 are respectively adjusted in height, after the lower guide mounting platform 220 is in a pitching state, its front and rear sides can still maintain a slidable connection with the outer frame 100 in the vertical direction.

[0058] In some embodiments, the first sliders 120 and the second sliders 130 are both provided with concave circular arc cavities 131, and the front and rear sides of the upper guide mounting platform 210 and the lower guide mounting platform 220 are both provided with circular arc portions 231 that are in rotational fit with the circular arc cavities 131.

[0059] For example, Figure 5As shown, the arc cavity 131 and the arc portion 231 cooperate to enable relative rotation and tight abutment between the side portions of the upper guide mounting platform 210 and the lower guide mounting platform 220 and the first slider 120 and the second slider 130. When the upper guide mounting platform 210 or the lower guide mounting platform 220 slides up and down, the two sides can be at different heights, that is, the upper guide mounting platform 210 and the lower guide mounting platform 220 can be in a front-back inclined position. The arc cavity 131 and the arc portion 231 can ensure that in this case, the two sides of the upper guide mounting platform 210 and the lower guide mounting platform 220 are tightly abutted and will not fall off. In this case, the hot-rolled steel plate formed from the threading channel can also be in an inclined structure, thereby adjusting the forming angle of the hot-rolled steel plate.

[0060] In some embodiments, two of the first sliders 120 are provided on the front and rear sides of the upper guide mounting platform 210, and two of the press-up lifting members 332 are correspondingly provided for one of the press-up power members 331. The press-up lifting members 332 are connected to the upper guide mounting platform 210 at the first sliders 120. Two of the second sliders 130 are provided on the front and rear sides of the lower guide mounting platform 220, and two of the press-down lifting members 432 are correspondingly provided for the press-down power member 431. The press-up lifting members 332 are connected to the upper guide mounting platform 210 at the second sliders 130.

[0061] For example, Figure 1 、 Figure 6 As shown, the outer frame 100 is a rectangular body and has four columns 110. The chutes are provided on the two columns 110 at the rear side and the front side. Two sliders are provided at both the front and rear sides of the upper guide mounting platform 210 and the front and rear sides of the lower guide mounting platform 220, and are slidably connected to the chutes on the columns 110 through the sliders, making the up-and-down sliding of the upper guide mounting platform 210 and the lower guide mounting platform 220 in the vertical direction smoother. As Figure 8 、 Figure 9 As shown, two of the press-up lifting members 332 are correspondingly provided for one of the power members. Then, the first lifting adjustment assembly 310 and the second lifting adjustment assembly 320 have a total of four press-up lifting members 332. The four press-up lifting members 332 are respectively connected to the upper guide mounting platform 210 at the four first sliders 120 to adjust the upper guide mounting platform 210. Similarly, four of the press-down power members 431 are respectively connected to the lower guide mounting platform 220 at the four second sliders 130 to adjust the lower guide mounting platform 220.

[0062] In some embodiments, a first driving member 511 for driving the first left roller system 510 and a second driving member 521 for driving the first right roller system 520 are provided on the upper guide mounting platform 210, and a third driving member 611 for driving the second left roller system 610 and a fourth driving member 621 for driving the second right roller system 620 are provided on the lower guide mounting platform 220.

[0063] In the specific implementation process, as Figure 1 , Figure 7 shown, the first driving member 511, the second driving member 521, the third driving member 611, and the fourth driving member 621 can all be selected as hydraulic cylinders. Through hydraulic action, the positions of the first left roller system 510, the first right roller system 520, the second left roller system 610, and the second right roller system 620 can be adjusted left and right, so as to adjust the width and position angle of the threading channel to adapt to the dimensions required for hot-rolled steel plate forming.

[0064] In some embodiments, the two upper roller system units are symmetrically arranged along the central plane of the upper guide mounting platform, the two lower roller system units are symmetrically arranged along the central plane of the lower guide mounting platform, and the double-flow guide structure is symmetrically arranged along the central plane of the upper guide mounting platform and / or the central plane of the lower guide mounting platform; the first left roller system and the first right roller system are symmetrically arranged, and the second left roller system and the second right roller system are symmetrically arranged.

[0065] For example Figures 1 to 5 , and Figure 7 in, the double-flow guide structure is symmetrically arranged along the central plane of the upper guide mounting platform 210 and / or the central plane of the lower guide mounting platform 220. Then, when adjusting the dimensions of the two threading channels, the width and position can be symmetrically adjusted, so that the dimensions of the two threading channels can be quickly adjusted to be consistent, further improving the efficiency of steel plate forming. The first left roller system 510 and the first right roller system 520 are symmetric, and the second left roller system 610 and the second right roller system 620 are symmetric, so that the formed threading channels are symmetric; the first left roller system 510, the first right roller system 520, the second left roller system 610, and the second right roller system 620 all move left and right in the horizontal direction to adjust the width and position angle of the threading channel.
