[0051] In the description of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be a direct connection or an indirect connection through an intermediate medium. It can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] like Figure 1 The present embodiment provides a bending and arc forming device for a U-shaped trough plate 4, wherein an introduction mechanism 2, a roller bending mechanism 1, a cutting mechanism 3 and a central control system are sequentially arranged along the transportation direction of the U-shaped trough plate 4. The central control system is used for the automatic program control of each mechanism. Through this series of automatic equipment, a vertical U-shaped trough plate 4 can be bent horizontally to form a curved U-shaped trough plate 4 with a certain curvature.

[0053] like Figure 2 The introduction mechanism 2 includes a roller transport group 21, which is composed of a series of rollers, and the U-shaped trough plate 4 is transported by the rolling of the rollers. The roller transport group 21 includes two groups of roller assemblies 22 arranged on the left and right sides, each group of roller assemblies 22 includes an upper roller 23 and a lower roller 24, and the upper rollers 23 and the lower rollers 24 on both sides are symmetrically arranged. Through the pressing of the upper rollers 23 and the lower rollers 24 of the roller groups on both sides and the continuous rotation of the rollers, the rollers transport the U-shaped trough plate 4 at the corresponding pressure and speed.

[0054] like Figure 3A cutting mechanism 3 is arranged at the rear side of the roller bending mechanism 1. The cutting mechanism 3 includes a cutting window 31 and a cutting knife group 32 arranged in the cutting window 31. When the arc-shaped U-shaped groove plate 4 passes through the window, the arc-shaped U-shaped groove plate 4 is sheared by the cutting knife group 32.

[0055] like Figure 4 The roller bending mechanism 1 includes a support frame 11 and two groups of fixed pressure roller groups 12 and one group of dynamic pressure roller groups 13 arranged on the support frame 11; the two groups of fixed pressure roller groups 12 are symmetrically arranged on both sides of one group of dynamic pressure roller groups 13, and the two groups of fixed pressure roller groups 12 are arranged on the same side. Through the lateral movement of the middle dynamic pressure roller group 13 and the positioning of the fixed pressure roller groups 12 on both sides, the vertical U-shaped groove plate 4 is transversely bent to produce a certain curvature. The rollers in the fixed pressure roller group 12 and the dynamic pressure roller group 13 are both unpowered rollers, and are rolled and transported along 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. A convex ring 123 is provided at the upper end of the fixed roller 122. The U-shaped groove plate 4 is folded inward at its U-shaped groove opening 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 transversely bent, the fixed roller 122 is located on the outer side edge 43 of the U-shaped groove plate 4, and the side surface of the fixed roller 122 is against the outer side surface of the U-shaped groove plate 4, and the outer side edge 43 of the U-shaped groove plate 4 is laterally limited to ensure that the middle lateral force can form an arc deformation. The lower edge of the convex ring 123 abuts against the folded edge 42 , and the convex ring 123 cooperates with the fixed roller 122 to shape the folded edge 42 and the side edge 43 of the U-shaped groove plate 4 to prevent the folded edge 42 of the U-shaped groove plate 4 from deforming or warping during the force application process.

[0057] like Fig.10The fixed roller 122 is mounted on the mounting seat 121 through a rotating shaft 124. A plurality of first gaskets 125 can be mounted on the rotating shaft 124. The installation height of the fixed roller 122 can be changed by changing the position distribution of the first gaskets 125, so as to adjust the height position of the convex ring 123 to meet the pressing requirements of U-shaped groove plates 4 of different depths. The U-shaped groove plates 4 have different depths, and the heights of the side edges 43 and the folded edges 42 are also different. In order to enable the U-shaped groove plates 4 to pass through and form the pressing and shaping of the folded edges 42, the height of the convex ring 123 is changed by adjusting the position of the first gaskets 125, so that it can adapt to the folded edges 42 of different heights, ensuring the smooth passage of the U-shaped groove plates 4. The rotating shaft 124 is locked on the mounting seat 121 by a nut 126. The rotating shaft 124 can be removed by the nut 126, and then the first gasket 125 can be removed relative to the rotating shaft 124. After a suitable number of first gaskets 125 are mounted on the rotating shaft 124, the rotating shaft 124 is locked on the mounting seat 121 again and tightened by the nut 126 until the first gasket 125 is against the mounting seat 121.

[0058] Mounting openings are provided at the upper and lower ends of the mounting seat 121, and the upper and lower ends of the rotating shaft are locked by nuts 126. When adjusting the height of the fixed roller 122, after the rotating shaft is disassembled, a suitable number of first gaskets 125 are selected and installed above the fixed roller 122, and the remaining first gaskets 125 are installed below the fixed roller 122. The installation height of the fixed roller 122 can be adjusted by adjusting the position and number of the upper and lower first gaskets 125.

[0059] The dynamic pressure roller group 13 includes a first pressure roller group 131 for lateral pressing, a second pressure roller group 133 and a movable seat 135 for mounting the two pressure roller assemblies 22. Slide seats 136 are arranged on both sides of the bottom of the movable seat 135. Two rails 111 are arranged on the support frame 11 accordingly. The slide seats 136 are slidably matched with the rails 111 (such as Figure 5 The side edge 43 of the support frame 11 is provided with a driving mechanism 14, which is driven by a gas rod (such as Figure 4 ), whose driving end is connected to the moving seat 135. Driven by the gas rod, the moving seat 135 can move back and forth in the horizontal direction under the cooperation of the slide seat 136 and the track 111. The driving mechanism 14 is arranged on the opposite side of the fixed pressure roller group 12. When the moving seat 135 moves in the direction toward the fixed pressure roller group 12, the first pressure roller group 131 and the second pressure roller group 133 realize the horizontal pressing of the U-shaped groove plate 4, so that it is bent in the horizontal direction.

[0060] like Figure 6-7The first pressure roller group 131 is arranged on the opposite side of the two fixed pressure roller groups 12, and the second pressure roller group 133 is arranged on the opposite side of the first pressure roller group 131. On the movable seat 135, the first pressure roller group 131 is a fixed component relative to the second pressure roller group 133, and the second pressure roller group 133 is a movable group. The first pressure roller group 131 is fixed on the movable seat 135 and moves with the movement of the movable seat 135. The second pressure roller group 133 is movably arranged on the movable seat 135. The first pressure roller group 131 is located at the outer side 43 of the U-shaped groove plate 4, and the second pressure roller group 133 is located in the notch of the U-shaped groove plate 4.

[0061] When a section of U-shaped groove plate 4 is conveyed into the roller bending mechanism 1, two groups of fixed pressure roller groups 12 limit the two ends of the section of U-shaped groove plate 4 laterally, and the side of the fixed roller wheel 122 abuts against the outer side of the left side of the end of the U-shaped groove plate 4. The first pressure roller group 131 and the second pressure roller group 133 apply transverse bending to the middle part of the section of U-shaped groove plate 4 through the movement of the movable seat 135. The side of the roller in the first pressure roller group 131 abuts against the outer side of the right side of the middle part of the U-shaped groove plate 4. The first pressure roller group 131 and the two groups of fixed pressure roller groups 12 press the two sides of the U-shaped groove plate 4, so that the middle part of the U-shaped groove plate 4 can produce transverse bending deformation. The second pressure roller group 133 is placed in the notch of the U-shaped groove plate 4, and the rollers in the second pressure roller group 133 The side surface abuts against the inner side surface of the left side of the middle of the U-shaped groove plate 4. When the driving mechanism 14 starts to drive the movable seat 135 to move toward the fixed pressure roller group 12, the first pressure roller group 131 and the second pressure roller group 133 simultaneously press the middle of the U-shaped groove plate 4 laterally under the drive of the movable seat 135. By simultaneously pressing the two sides of the middle of the U-shaped groove plate 4 by the first pressure roller group 131 and the second pressure roller group 133, the U-shaped shape of the U-shaped groove plate 4 can be kept from being deformed during transverse bending, and only transverse bending occurs. With the movement of the movable seat 135, the middle of the U-shaped groove plate 4 begins to gradually deform, forming a transverse bend. The pressing of U-shaped groove plates 4 with different curvatures can be achieved by setting the movement of the movable seat 135.

[0062] In order to meet the lateral bending deformation of the U-shaped groove plate 4 with different widths, such as Figure 6 The second pressing roller group 133 includes a first pressing roller group 132 and a second pressing roller group 133. A driving module 134 is disposed at the upper end of the moving seat 135. Fig.11 The driving module 134 is used to drive the first pressing roller group 132 and the second pressing roller group 133 to move horizontally. When performing horizontal pressing, a suitable first pressing roller group 132 or second pressing roller group 133 is selected for pressing cooperation according to the width of the U-shaped groove plate 4. The driving module 134 is adjusted by horizontal movement so that the roller side of the pressing roller group is against the inner side edge 43 of the U-shaped groove plate 4.

[0063] The diameter of the roller of the first roller group 132 is smaller than the diameter of the roller of the second roller group 133. Fig. 9, the first pressing roller group 132, the first pressing roller group 131 and the U-shaped groove plate 4 with a smaller width. Fig.14 A roller assembly 132 includes a first roller 1321, a first rotating shaft 1322 and a plurality of second gaskets 1323. The first rotating shaft 1322 is mounted on a driving module 134. A groove 1324 is provided at the bottom of the first roller 1321. A screw 1325 is screwed into the groove 1324. A screw 1325 hole 1316 is provided at the bottom of the first rotating shaft 1322. The first roller 1321 is locked on the first rotating shaft 1322 by cooperating with the screw 1325. The first roller 1321, the second gasket 1323 and the first rotating shaft 1322 are detachably connected by cooperating with the screw 1325 hole 1316. Fig.15 An annular plate 1326 is fixed on the first rotating shaft 1322 to form an installation position for the second gasket 1323. The second gasket 1323 is arranged between the first roller 1321 and the annular plate 1326. The number of second gaskets 1323 installed between the annular plate 1326 and the first roller 1321 is adjustable. By adjusting the number of second gaskets 1323, the interval between the annular plate 1326 and the first roller 1321 can be adjusted, so that the height of the first roller 1321 can be adjusted to adapt to U-shaped groove plates 4 of different depths. The diameter of the second gasket 1323 is smaller than the diameter of the first roller 1321. When the U-shaped groove plate 4 is pressed, the folded edge 42 of the U-shaped groove plate 4 is against the upper edge of the first roller 1321 to shape the folded edge 42 (such as Fig. 9 ).like Fig.14 An annular gasket 1327 is provided on the upper end surface of the first roller 1321 . The diameter of the annular gasket 1327 matches the diameter of the first roller 1321 , and the folded edge 42 abuts against the upper edge surface of the annular gasket 1327 .

[0064] like Figure 8The second pressure roller group 133 includes a second roller 1331, a third roller 1332 and a plurality of third gaskets 1333. The second roller 1331 is placed on the outer edge 43 of one side of the U-shaped groove plate 4, and the third roller 1332 is placed on the inner edge 43 of the corresponding side of the U-shaped groove plate 4. The second roller 1331 and the third roller 1332 cooperate to shape the folded edge 42 of the U-shaped groove plate 4. The third roller 1332 is connected to the driving module 134 through the second rotating shaft, and the third gasket 1333 is mounted on the second rotating shaft. The third roller 1332 and the third gasket 1333 are disassembled relative to the second rotating shaft, and the installation height of the third roller 1332 is adjusted by adjusting the assembly quantity of the third gasket 1333 to adapt to the depth of the U-shaped groove plate 4. The installation height adjustment and disassembly structure of the third gasket 1333 and the third roller 1332 are consistent with the installation height adjustment and disassembly structure of the first roller 1321 in a pressure roller group 132. The disassembly structure is made removable by locking the screw 1325 hole 1316 with the screw 1325, which will not be described in detail here.

[0065] like Fig.16 The driving module 134 includes a transverse module 1341 and a lifting mechanism 1342. The transverse module 1341 is a linear driving module 134. The transverse movement of the first roller 1321, the second roller 1331 and the third roller 1332 is achieved by cooperating with the slide rail 1344 and the slider 1343. The first roller 1321, the second roller 1331 and the third roller 1332 move laterally synchronously. The lifting mechanism 1342 adopts a gas rod. The second roller 1331 is connected to the lifting mechanism 1342, and the second roller 1331 can be lifted up and down.

[0066] like Figure 8 When pressing a U-shaped groove plate 4 with a larger width, the second pressing roller group 133 is selected for pressing cooperation. The side edge 43 of the U-shaped groove plate 4 passes through the gap between the second roller 1331 and the third roller 1332 in the second pressing roller group 133. The second roller 1331 and the third roller 1332 are moved horizontally to a suitable width position under the drive of the transverse movement module 1341. The second roller 1331 is driven by the lifting mechanism 1342 to adjust the height position up and down. The third roller 1332 is adjusted according to the number of the third gaskets 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. The gap allows the folded edge 42 of the U-shaped groove plate 4 to pass through, thereby achieving the shaping of the folded edge 42. By setting the lifting mechanism 1342 and the third gasket 1333, it can be achieved that U-shaped groove plates 4 of different depths can pass smoothly. Figure 8During the transportation and pressing process of the U-shaped groove plate 4, the third roller 1332 and the second roller 1331 are respectively arranged on the inside and outside of one side 43 of the U-shaped groove plate 4 under the drive of the transverse module 1341, and the side surface of the third roller 1332 is abutted against the inner side surface of the side 43. Under the height adjustment of the gasket, the upper edge surface of the third roller 1332 abuts against the lower end surface of the folded edge 42, and the lower edge surface of the second roller 1331 abuts against the upper end surface of the folded edge 42 under the drive of the lifting mechanism 1342, thereby realizing the shaping of the folded edge 42.

[0067] The second roller 1331 is provided with a step surface, and the upper end surface of the step surface is used as the lower edge surface of the upper end surface of the folded edge 42. When the U-shaped groove plate 4 is transported and pressed, the side surface of the step surface is against the outer side surface of the U-shaped groove plate 4, and forms an inner and outer shaping of the side edge 43 of the U-shaped groove plate 4 with the side surface of the third roller 1332 (such as Figure 8 ).

[0068] like Fig. 9 When pressing a U-shaped groove plate 4 with a smaller width, a pressing roller group 132 is selected for pressing cooperation. The first roller 1321 is driven by the transverse module 1341 to move transversely to a position of suitable width. The first roller 1321 adjusts the height position according to the number of second gaskets 1323 to facilitate the smooth passage of the folded edge 42 of the U-shaped groove plate 4. During the transportation and pressing process of the U-shaped groove plate 4, the side of the first roller 1321 is driven by the transverse module 1341 to abut against the inner side of one side of the U-shaped groove plate 4, and the folded edge 42 of the U-shaped groove plate 4 abuts against the upper edge of the first roller 1321, thereby achieving the shaping of the folded edge 42.

[0069] In order to meet the requirements of different depths of the U-shaped groove plate 4, the first pressing roller group 131 includes a fourth roller 1311, a fourth gasket 1312, a positioning ring 1317 and a pressing block 1313 (such as Fig.13 ), a third rotating shaft 1314 is arranged on the movable seat 135, a fourth roller 1311 is rotatably mounted on the third rotating shaft 1314, and a fourth gasket 1312 and a positioning ring 1317 are detachably mounted on the third rotating shaft 1314. The fourth roller 1311, the fourth gasket 1312 and the positioning ring 1317 are sequentially assembled on the third rotating shaft 1314 along the axial direction, a pressing block 1313 is arranged above the third rotating shaft 1314, and the positioning ring 1317 is pressed by the pressing block 1313 to realize the axial fixation of the positioning ring 1317 and the fourth gasket 1312.

[0070] like Fig.12Specifically, the pressing block 1313 is driven by a lifting screw 1315 and can move up and down along the axial direction of the third rotating shaft 1314. The pressing block 1313 has a hole 1316 at one end facing the third rotating shaft 1314, and the diameter of the hole 1316 is adapted to the diameter of the third rotating shaft 1314. When an appropriate number of fourth gaskets 1312 are assembled on the third rotating shaft 1314, the pressing block 1313 is driven downward by the lifting screw 1315, and the third rotating shaft 1314 is inserted into the hole 1316 of the pressing block 1313. The pressing block 1313 descends until it rests on the positioning ring 1317, thereby realizing axial fixation of the positioning ring 1317.

[0071] like Figure 8 When pressed on the U-shaped groove plate 4, the lower edge surface of the positioning ring 1317 rests 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. The installation height of the positioning ring 1317 is adjusted by adjusting the height of the fourth gasket 1312 to meet the shaping of folded edges 42 of different heights.

[0072] The above is only a preferred specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the present invention within the technical scope disclosed by the present invention shall be deemed to infringe the protection scope of the present invention.
