DETAILED DESCRIPTION
[0014] The present application will be further described in detail below in combination with the drawings and specific embodiments.
[0015] As Figure 1 shown, a steel plate pre-bending treatment device for tower manufacturing comprises, from bottom to top, a base 1, a supporting plate 2, a pressing plate 3 and a top plate 4 arranged in parallel; the base 1 and the supporting plate 2 are connected by a plurality of first support columns 5; the supporting plate 2 and the top plate 4 are connected by a plurality of second support columns 6; the top plate 4 and the pressing plate 3 are connected by an oil cylinder 7 for driving the pressing plate 3 to move vertically up and down; the pressing plate 3 is provided with a lower pressing assembly; a supporting assembly is arranged between the supporting plate 2 and the base 1; As Figure 2 shown, the lower pressing assembly comprises a first sliding groove 8 opened on the lower side of the pressing plate 3 along the left-right direction; two support bars 9 are slidably connected in the first sliding groove 8; the support bars 9 are arranged along the front-rear direction and distributed left and right in the first sliding groove 8; an arc-shaped elastic steel sheet 10 is arranged below the pressing plate 3; the elastic steel sheet 10 can be made of high-elastic spring steel material, which can adapt to changes in a large range of bending amplitude and can withstand repeated bending and recovery; the width direction of the elastic steel sheet 10 is arranged along the front-rear direction; the left and right ends of the elastic steel sheet 10 are respectively connected with the support bars 9 correspondingly; the pressing plate 3 is provided with a first adjusting mechanism for driving the two support bars 9 to move relatively close to or relatively far away from each other; As Figure 1As shown, the supporting assembly comprises a through slot 11 opened on the supporting plate 2 along the left-right direction; the arc-shaped protruding end of the elastic steel sheet 10 is used to pass through the through slot 11; the upper end of the supporting plate 2 is provided with two limiting blocks 12; the two limiting blocks 12 are symmetrically distributed on the outer side of the elastic steel sheet 10, one on the left and one on the right; the end faces of the two limiting blocks 12 close to each other are provided as supporting faces 13; the supporting faces 13 are inclined surface structures; the spacing between the lower ends of the supporting faces 13 on the two sides is smaller than the spacing between the upper ends; the lower end of the limiting block 12 is fixed with a lifting frame 14; the upper side of the base 1 is provided with a second sliding groove 15 opened along the left-right direction; the lower end of the lifting frame 14 is in sliding connection with the second sliding groove 15 in correspondence; the base 1 is provided with a second adjusting mechanism for driving the two lifting frames 14 to relatively close to or relatively away from each other.
[0016] In the scheme, the first adjusting mechanism is used to drive the two supporting strips 9 to relatively close to or relatively away from each other, to change the bending degree of the elastic steel sheet 10, so that the bending curvature of the arc-shaped protruding end of the elastic steel sheet 10 corresponds to the required bending curvature of the steel plate to be bent. Then, the second adjusting mechanism is used to drive the two lifting frames 14 to relatively close to or relatively away from each other, to change the spacing between the two limiting blocks 12 and the elastic steel sheet 10, so that the spacing between the two limiting blocks 12 adapts to the requirement of the spacing between the two sides under different bending curvatures of the steel plate. Then, the oil cylinder 7 is used to drive the pressing plate 3 to press down, and the elastic steel sheet 10 can press and bend the steel plate into a corresponding bending curvature.
[0017] The bending elastic steel sheet 10 has a smaller area compared with the steel plate to be bent, is supported by the two supporting strips 9, and the steel plate required by the tower is usually thin, and in addition, is limited by the two limiting blocks 12. Therefore, the pressure required for pressing and bending the steel plate is not too large, the elastic steel sheet 10 can maintain a stable bending state to press and bend the steel plate, and the problem of excessive deformation of the elastic steel sheet 10 under pressure is avoided, and a large error in the bending curvature of the steel plate during pressing and bending can be avoided.
[0018] In the above process, the bending curvature of the arc-shaped protruding end of the elastic steel sheet 10 can be flexibly changed by adjusting the spacing between the two supporting strips 9, so that the device can bend the steel plate into various required curvatures, greatly reducing the equipment cost required for tower manufacturing.
[0019] As shown in the figure, Figure 2 The first adjusting mechanism comprises a first speed reducer motor 16 fixed on the right end of the pressing plate 3, a first lead screw 17 connected in the first sliding groove 8 along the left-right direction; the first lead screw 17 is in rotational connection with the pressing plate 3; the first lead screw 17 is driven to rotate by the first speed reducer motor 16; the threads on the left and right sides of the first lead screw 17 are in opposite directions; the two supporting strips 9 are in corresponding threaded connection with the left and right sides of the first lead screw 17 respectively.
[0020] The first screw rod 17 is driven to rotate by the first speed reducer 16. Since the threads on the left and right sides of the first screw rod 17 are opposite in rotation direction, the support bars 9 on the left and right sides can be simultaneously close or far away.
[0021] As shown in Figure 1 The second adjusting mechanism includes a second speed reducer 18 fixed at the right end of the base 1, a second screw rod 19 connected in the left-right direction in the second sliding groove 15, the second screw rod 19 is rotationally connected with the base 1, the second screw rod 19 is driven to rotate by the second speed reducer 18, the threads on the left and right sides of the second screw rod 19 are opposite in rotation direction, and the two lifting frames 14 are respectively connected with the corresponding threads on the left and right sides of the second screw rod 19.
[0022] The second screw rod 19 is driven to rotate by the second speed reducer 18. Since the threads on the left and right sides of the second screw rod 19 are opposite in rotation direction, the lifting frames 14 on the left and right sides can be simultaneously close or far away, so as to realize the close or far away of the limiting block 12.
[0023] As shown in Figures 1-2 The first sliding groove 8 and the second sliding groove 15 are respectively fixed with a slide rod 20 in the left-right direction, the support bars 9 are slidingly connected with the slide rod 20 in the first sliding groove 8, and the lifting frames 14 are slidingly connected with the slide rod 20 in the second sliding groove 15.
[0024] The arrangement of the slide rod 20 can make the sliding of the support bars 9 or the lifting frames 14 more smooth, and respectively reduce the excess friction due to unstable movement between the first sliding groove 8 and the second sliding groove 15.
[0025] As shown in Figure 2 The bracket 21 is fixed at the middle of the lower end of the pressing plate 3, the telescopic device 22 is connected at the lower end of the bracket 21, the support rod 23 is vertically downward and connected at the lower end of the telescopic device 22, the support rod 23 is arranged in the front-back direction, and the support rod 23 is in abutment with the inner side of the arc-shaped protruding end of the elastic steel sheet 10.
[0026] The abutment of the support rod 23 with the inner side of the arc-shaped protruding end of the elastic steel sheet 10 is controlled by the telescopic device 22, which can reinforce the shape of the curved elastic steel sheet 10, further improve the shape stability of the elastic steel sheet 10 when the steel plate is pressed, and further reduce the error of the bending curvature of the steel plate when the steel plate is bent.
