[0052] As Figure 1 , the present embodiment provides a U-shaped groove plate 4 bending and forming equipment, which is provided with an import mechanism 2, a roll bending mechanism 1, a cutting mechanism 3 and a central control system in sequence along the direction of U-shaped groove plate 4 transportation. The central control system is used for automatic program control of each mechanism, and a series of automatic equipment is used to realize transverse bending of a vertical U-shaped groove plate 4 to form a curved U-shaped groove plate 4 with a certain arc.

[0053] As Figure 2 , the import mechanism 2 includes a roller transportation group 21 composed of a series of rollers and realizes transportation of the U-shaped groove plate 4 through rolling of the rollers. The roller transportation group 21 includes two groups of press roller assemblies 22 arranged on the left and right sides, each group of press roller assemblies 22 includes an upper press roller 23 and a lower press roller 24, and the upper press rollers 23 and the lower press rollers 24 on the two sides are symmetrically arranged. Through pressing of the upper press rollers 23 and the lower press rollers 24 of the two groups of press roller assemblies and continuous rotation of the rollers, the rollers transport the U-shaped groove plate 4 under corresponding pressure and speed.

[0054] As Figure 3A cutting mechanism 3 is arranged at the rear side of the roll bending mechanism 1, which includes a cutting window 31 and a cutter set 32 arranged in the cutting window 31. When the arc-shaped U-shaped groove plate 4 passes through the window, the cutter set 32 performs shearing of the arc-shaped U-shaped groove plate 4.

[0055] As Figure 4 The roll bending mechanism 1 includes a support frame 11, two sets of fixed pressure roller groups 12 and one set of dynamic pressure roller groups 13 arranged on the support frame 11. The two sets of fixed pressure roller groups 12 are symmetrically arranged on both sides of the set of dynamic pressure roller groups 13, and the two sets of fixed pressure roller groups 12 are arranged on the same side. Through the transverse movement of the intermediate dynamic pressure roller group 13, the positioning of the two side fixed pressure roller groups 12 is matched to bend the vertical U-shaped groove plate 4 transversely to generate a certain arc. The rollers in the fixed pressure roller group 12 and the dynamic pressure roller group 13 are all unpowered rollers, which roll with the transportation of the U-shaped groove plate 4.

[0056] The fixed pressure roller group 12 includes a mounting seat 121 and a fixed roller 122 assembled on the mounting seat 121. The upper end of the fixed roller 122 is provided with a convex ring 123. The U-shaped groove plate 4 is inwardly folded at the U-shaped groove 41 to form a folded edge 42. When the U-shaped groove plate 4 passes through the fixed roller 122, the folded edge 42 cooperates with the convex ring 123. When the U-shaped groove plate 4 is bent transversely, the fixed roller 122 is located at the outer side edge 43 of the U-shaped groove plate 4, and the side surface of the fixed roller 122 abuts against the outer side surface of the U-shaped groove plate 4 to limit the transverse position of the outer side edge 43 of the U-shaped groove plate 4, ensuring that the transverse stress in the middle can form an arc-shaped deformation. The lower edge surface of the convex ring 123 abuts against the folded edge 42, and the convex ring 123 cooperates with the fixed roller 122 to fix the folded edge 42 and the side edge 43 of the U-shaped groove plate 4, avoiding deformation or lifting of the folded edge 42 of the U-shaped groove plate 4 during stress.

[0057] As Figure 10The fixed roller wheel 122 is installed on the mounting seat 121 through a rotating shaft 124, the rotating shaft 124 can be sleeved with a plurality of first gaskets 125, the installation height of the fixed roller wheel 122 can be changed by changing the position distribution of the first gaskets 125, the height position of the convex ring 123 is adjusted to meet the pressing needs of the U-shaped groove plate 4 with different depths. The depth of the U-shaped groove plate 4 is different, the height of the side edge 43 and the folded edge 42 is also different, in order to enable the U-shaped groove plate 4 to pass through and form the pressing and shaping of the folded edge 42, the height of the convex ring 123 is changed through the position adjustment of the first gaskets 125, so that it can adapt to the folded edge 42 with different heights, and the smooth passing of the U-shaped groove plate 4 is ensured. The rotating shaft 124 is locked on the mounting seat 121 through a nut 126, the rotating shaft 124 can be disassembled through the nut 126, then the first gaskets 125 can be disassembled relative to the rotating shaft 124, after the appropriate number of first gaskets 125 are sleeved on the rotating shaft 124, the rotating shaft 124 is relocked on the mounting seat 121, and the nut 126 is tightened until the first gaskets 125 abut against the mounting seat 121.

[0058] The mounting seat 121 is provided with mounting holes in the upper and lower positions, the upper and lower ends of the rotating shaft are locked through the nut 126, when the height of the fixed roller wheel 122 is adjusted, the rotating shaft is disassembled, the appropriate number of first gaskets 125 are selected and installed above the fixed roller wheel 122, and the remaining first gaskets 125 are installed below the fixed roller wheel 122, the adjustment of the position and number of the upper and lower first gaskets 125 is used to adjust the installation height of the fixed roller wheel 122.

[0059] The dynamic pressure roller group 13 includes a first pressure roller group 131 for transverse pressing, a second pressure roller group 133, and a moving seat 135 for mounting the two groups of pressure roller assemblies 22, the bottom of the moving seat 135 is provided with sliding seats 136, and two tracks 111 are correspondingly arranged on the support frame 11, and the sliding seats 136 and the tracks 111 are in sliding fit (as Figure 5 ) The side edge 43 of the support frame 11 is provided with a driving mechanism 14, the driving mechanism 14 adopts air rod driving (as Figure 4 ), the driving end of the driving mechanism 14 is connected with the moving seat 135, the moving seat 135 moves back and forth along the transverse direction under the cooperation of the sliding seats 136 and the tracks 111 through the driving of the air rod. The driving mechanism 14 is arranged on the opposite side of the fixed pressure roller group 12, when the moving seat 135 moves towards the fixed pressure roller group 12, the transverse pressing of the U-shaped groove plate 4 is realized through the first pressure roller group 131 and the second pressure roller group 133, so that the U-shaped groove plate 4 is transversely bent.

[0060] As Figures 6-7, the first compression roller group 131 is arranged on the opposite side of the two sets of fixed compression roller groups 12, the second compression roller group 133 is arranged on the opposite side of the first compression roller group 131, the first compression roller group 131 is a fixed component relative to the second compression roller group 133 on the moving seat 135, the second compression roller group 133 is a movable component, the first compression roller group 131 is fixed on the moving seat 135 and moves with the moving seat 135, the second compression roller group 133 is movably arranged on the moving seat 135, the first compression roller group 131 is located on the outer side 43 of the U-shaped groove plate 4, and the second compression roller group 133 is located in the groove of the U-shaped groove plate 4.

[0061] When a section of the U-shaped groove plate 4 is conveyed into the roller bending mechanism 1, the two sets of fixed compression roller groups 12 limit the two ends of the section of the U-shaped groove plate 4 in the transverse direction, and the side surface of the fixed roller 122 abuts against the outer side surface of the left side of the end of the U-shaped groove plate 4. The first compression roller group 131 and the second compression roller group 133 apply transverse bending to the middle part of the section of the U-shaped groove plate 4 through the movement of the moving seat 135, the side surface of the roller in the first compression roller group 131 abuts against the outer side surface of the right side of the middle part of the U-shaped groove plate 4, and the two sides of the U-shaped groove plate 4 are pressed by the first compression roller group 131 and the two sets of fixed compression roller groups 12, so that the middle part of the U-shaped groove plate 4 can be transversely bent and deformed, the second compression roller group 133 is arranged in the groove of the U-shaped groove plate 4, and the side surface of the roller in the second compression roller group 133 abuts against the inner side surface of the left side of the middle part of the U-shaped groove plate 4, when the driving mechanism 14 starts to drive the moving seat 135 to move towards the fixed compression roller groups 12, the first compression roller group 131 and the second compression roller group 133 simultaneously press the middle part of the U-shaped groove plate 4 in the transverse direction under the drive of the moving seat 135, and the U-shaped shape of the U-shaped groove plate 4 can be kept from being deformed and only transversely bent through the simultaneous pressing of the two sides of the middle part of the U-shaped groove plate 4 by the first compression roller group 131 and the second compression roller group 133. With the movement of the moving seat 135, the middle part of the U-shaped groove plate 4 starts to deform gradually and forms a transverse bend, and the pressing of the U-shaped groove plate 4 with different radii can be realized by setting the movement of the moving seat 135.

[0062] In order to meet the transverse bending deformation of U-shaped groove plates 4 with different widths, Figure 6 The second compression roller group 133 includes a compression roller group 132 and a second compression roller group 133, and a driving module 134 is arranged at the upper end of the moving seat 135, which is used to drive the compression roller group 132 and the second compression roller group 133 to move in the transverse direction, Figure 11 When pressing in the transverse direction, the appropriate compression roller group 132 or the second compression roller group 133 is selected according to the width of the U-shaped groove plate 4 to press and cooperate, and the side surface of the roller of the compression roller group abuts against the inner side 43 of the U-shaped groove plate 4 through the transverse movement adjustment of the driving module 134.

[0063] The diameter of the compression roller of the compression roller group 132 is smaller than that of the second compression roller group 133, Figure 9The cooperation of the first roller group 131 and the smaller-width U-shaped groove plate 4. As shown in Figure 14 The first roller group 132 includes a first roller 1321, a first rotating shaft 1322, and a plurality of second spacers 1323. The first rotating shaft 1322 is installed on the driving module 134. The bottom of the first roller 1321 is provided with a groove 1324. A screw 1325 is screwed in the groove 1324. The bottom of the first rotating shaft 1322 is provided with a screw hole 1316. The first roller 1321 is locked on the first rotating shaft 1322 by cooperating with the screw 1325. The detachable connection of the first roller 1321, the second spacers 1323, and the first rotating shaft 1322 is realized by the cooperation of the screw hole 1316 and the screw 1325. Figure 15 An annular plate 1326 is fixed on the first rotating shaft 1322 to form an installation position for the second spacers 1323. The second spacers 1323 are arranged between the first roller 1321 and the annular plate 1326. The number of the second spacers 1323 assembled between the annular plate 1326 and the first roller 1321 can be adjusted. The height of the first roller 1321 can be adjusted by adjusting the number of the second spacers 1323, so as to adapt to U-shaped groove plates 4 of different depths. The diameter of the second spacer 1323 is smaller than that of the first roller 1321. During the pressing process of the U-shaped groove plate 4, the folded edge 42 of the U-shaped groove plate 4 abuts against the upper edge surface of the first roller 1321 to shape the folded edge 42. Figure 9 As shown in Figure 14 An annular spacer 1327 is arranged on the upper end surface of the first roller 1321. The diameter of the annular spacer 1327 is adapted to the diameter of the first roller 1321. The folded edge 42 abuts against the upper edge surface of the annular spacer 1327.

[0064] As shown in Figure 8, the second roller 1331 and the third roller 1332 are used for the shaping of the edge 42 of the U-shaped groove plate 4. The third roller 1332 is connected with the driving module 134 through a second rotating shaft, and the third roller 1332 is sleeved with the third gasket 1333 on the second rotating shaft. The third roller 1332 and the third gasket 1333 are detachable relative to the second rotating shaft. The installation height of the third roller 1332 is adjusted by adjusting the number of the third gasket 1333, so as to adapt to the depth of the U-shaped groove plate 4. The adjustment and dismounting structure of the installation height of the third roller 1332 and the third gasket 1333 is consistent with the adjustment and dismounting structure of the installation height of the first roller 1321 in the first roller group 132. The dismounting structure is realized by locking the screw 1325 through the screw hole 1316 and the screw 1325, and will not be described here.

[0065] As shown in Figure 16 , the driving module 134 includes a horizontal movement module 1341 and a lifting mechanism 1342. The horizontal movement module 1341 is a linear driving module 134, which realizes the horizontal movement of the first roller 1321, the second roller 1331 and the third roller 1332 by cooperating with the slide rail 1344 and the slide block 1343. The first roller 1321, the second roller 1331 and the third roller 1332 move horizontally and synchronously. The lifting mechanism 1342 adopts a gas rod, and the second roller 1331 is connected with the lifting mechanism 1342. The second roller 1331 can be lifted up and down.

[0066] As shown in Figure 8 , when the pressing of the U-shaped groove plate 4 with a larger width is performed, the second roller group 133 is selected for pressing cooperation. The side edge 43 of the U-shaped groove plate 4 passes through the space between the second roller 1331 and the third roller 1332 in the second roller group 133. The second roller 1331 and the third roller 1332 are horizontally moved to the appropriate width position under the driving of the horizontal movement module 1341. The second roller 1331 is adjusted in height position up and down under the driving of the lifting mechanism 1342. The third roller 1332 is adjusted in height position under the number setting of the third gasket 1333. After adjustment, there is a gap between the lower edge surface of the second roller 1331 and the upper edge surface of the third roller 1332, which is used for the edge 42 of the U-shaped groove plate 4 to pass through, so as to realize the shaping of the edge 42. Through the setting of the lifting mechanism 1342 and the third gasket 1333, the U-shaped groove plate 4 with different depths can smoothly pass through.

The fourth roller 1311, the fourth gasket 1312 and the positioning ring 1317 are sequentially assembled on the third rotating shaft 1314 in the axial direction, and the pressing block 1313 is arranged above the third rotating shaft 1314, and the axial fixation of the positioning ring 1317 and the fourth gasket 1312 is realized by pressing the positioning ring 1317 through the pressing block 1313.

[0070] As Figure 12Specifically, the pressing block 1313 is driven by a lifting screw 1315 to move up and down along the axial direction of the third rotating shaft 1314, and a hole 1316 is formed in one end of the pressing block 1313 towards the third rotating shaft 1314, the diameter of the hole 1316 is matched with the diameter of the third rotating shaft 1314, when the third rotating shaft 1314 is assembled with the proper number of fourth gaskets 1312, the pressing block 1313 is driven by the lifting screw 1315 to move downwards, the third rotating shaft 1314 is inserted into the hole 1316 of the pressing block 1313, and the pressing block 1313 is lowered to abut against the positioning ring 1317, so that the axial fixation of the positioning ring 1317 is realized.

[0071] As Figure 8 When being pressed in the U-shaped groove plate 4, the lower edge surface of the positioning ring 1317 abuts against the upper end surface of the folded edge 42 of the U-shaped groove plate 4 to form the shaping of the folded edge 42, and the installation height of the positioning ring 1317 is adjusted by adjusting the height of the fourth gasket 1312 to meet the shaping of the folded edge 42 with different heights.
