In the following description, details are listed for the purpose of explanation. It should be understood that one of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other instances, known structures and processes are not described in detail to avoid obscuring the description of the present application with unnecessary detail. Therefore, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles disclosed herein.

[0020] See Figure 8 The embodiment of the present application provides an anti-deformation welding mold for producing an arc-shaped plate unit 81, comprising: The support platform 1 is provided with at least one set of first connection holes along the length direction of the support platform 1; The support assembly 2 includes a support plate 21, which is connected to a group of the first connection hole positions. At least one group of second connection hole positions 22 is correspondingly provided at both ends of the support plate 21. The side of the support plate 21 away from the support platform 1 is a concave arc. The fastening mechanism 3 is correspondingly connected to a group of the second connection hole positions 22; The rotating mechanism is located at the bottom of the supporting platform 1 .

[0021] It can be understood that the curvature of the arc of the side of the support plate 21 away from the support platform 1 is based on the curvature radius of the arc-shaped plate unit 81 it supports.

[0022] It can be understood that the setting of at least one set of second connection hole positions 22 can be applied to arc-shaped plate units 81 of different sizes, and the position of the fastening mechanism 3 can be adjusted to adapt to the fastening size of the arc-shaped plate unit 81.

[0023] In the present application, the arc-shaped surface of the support plate 21 fits the structural design of the curved surface of the arc-shaped plate unit 81, which can play a good supporting role during the welding process of the arc-shaped plate unit 81. At the same time, because the support plate 21 fits the outer diameter size design of the arc-shaped plate unit 81, by observing the gap size between the arc-shaped plate unit 81 and the support plate 21 during the welding process, the influence of welding deformation on the curvature change of the arc-shaped plate unit 81 can be monitored at any time; during the welding process of the arc-shaped plate unit 81, the arc-shaped plate unit 81 is fixed to the clamping mechanism 3 to form a structural external constraint to reduce the deformation influence of the welding heat output on the plate unit; through the setting of the rotating mechanism, the support platform 1 can have multiple parking gears, and during use, the parking gear at this location can be adjusted according to the different positions of the plate rib a of the arc-shaped plate unit 81 to be welded, so that the welding plate rib a is in the best welding state as much as possible, thereby ensuring the weld forming quality and weld size and improving the welding quality.

[0024] During use, the arc plate unit 81 to be welded is hoisted onto the supporting platform 1, and the longitudinal baseline of the arc plate unit 81 is aligned with the two ends of the longitudinal baseline 13 of the supporting platform 1, or the baseline spacing is strictly controlled, the position of the fixing mechanism 3 is adjusted, and the screw 34 is screwed to press the pressure plate 32 to press the arc plate unit 81 to ensure that the arc plate unit 81 is placed and fixed in place; by adjusting the hydraulic structure, the supporting platform 1 is at the required angle to ensure that the multiple plate ribs a of the arc plate unit 81 are in a relatively ideal welding state, and the welding operation on one side of the plate rib a is carried out; through the hydraulic structure, the angle of the supporting platform 1 is adjusted to weld the weld on the other side of the arc plate unit 81; after the welding is completed, the supporting platform 1 is adjusted to a horizontal state by adjusting the hydraulic structure, the lifting screw 34 is loosened, the arc plate unit 81 is hoisted, and it is transferred to the next process.

[0025] It can be understood that the hydraulic structure controls the output direction of the bidirectional power pump by the forward and reverse rotation of the motor, and then delivers the hydraulic oil to the cylinder through the control valve group to realize the reciprocating motion and up and down extension of the piston rod. This structure is well known in the art and will not be repeated here.

[0026] See Figure 1 In some embodiments, the support platform 1 includes a plurality of longitudinal beams 12 and a plurality of transverse beams 11 perpendicular to the longitudinal beams 12 , and a longitudinal base line 13 located in the middle of the support platform 1 is provided along the length direction of the longitudinal beams 12 .

[0027] It can be understood that the longitudinal beams 12 are fixed to the transverse beams 11 by welding.

[0028] For example, H-shaped steel is used in the transverse direction, and channel steel is used in the longitudinal beam 12 .

[0029] It can be understood that the longitudinal base line 13 is provided to assist in the alignment and positioning of the welded plate units.

[0030] It can be understood that the width and length of the support platform 1 are given in consideration of the track width and longitudinal formation of the welding robot.

[0031] In some embodiments, each of the crossbeams 11 is provided with at least one group of first connection holes along its length direction, and each of the crossbeams 11 is correspondingly provided with the support assembly 2 and the fastening mechanism 3 .

[0032] It can be understood that a corresponding support plate 21 can be provided on each crossbeam 11 , and a corresponding fastening mechanism 3 is provided on each support plate 21 .

[0033] In some embodiments, support plates 21 may be provided on some beams 11 , while not provided on other beams 11 , that is, support plates 21 are provided at intervals on the beams 11 , and each support plate 21 is provided with a corresponding fixing mechanism 3 .

[0034] It can be understood that a plurality of support plates 21 are sequentially arranged along the length direction of the arc-shaped plate unit 81 , which can play a good supporting role during the welding process of the arc-shaped plate unit 81 .

[0035] See Figure 2 In some embodiments, the side of the support plate 21 close to the support platform 1 is flat, and first connecting plates 23 are respectively provided at both ends of the support plate 21 close to the support platform 1. The first connecting plates 23 are connected to the support platform 1 through first bolts.

[0036] In some embodiments, the first connecting plate 23 is connected to the flange plate on the beam 11 through a first bolt.

[0037] It can be understood that the anti-deformation welding profile of the present application mainly relies on the direct contact between the support plate 21 and the arc-shaped plate unit 81 to play a supporting role.

[0038] Exemplarily, the support plate 21 is a thin steel plate, and the thickness of the support plate 21 is 16 mm to 22 mm, for example, it can be 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, 21 mm, 22 mm, etc. Within the thickness range, the weight of the support plate 21 is also considered on the basis of fully considering the stiffness of the support plate 21 itself, so as to facilitate disassembly.

[0039] See Figure 3In some embodiments, each of the fixing mechanisms 3 includes a second connecting plate 35, and a third connecting hole position corresponding to the second connecting hole position 22 is provided on the second connecting plate 35. The upper part of the second connecting plate 35 is connected to a pressing plate 32 through a first rotating shaft 31. The pressing plate 32 has a first end and a second end that are relatively arranged. The first end is close to the vertical center line of the support plate 21, and a protrusion 36 is provided on the second connecting plate 35 at the lower part of the second end. A nut 33 is fixed on the outer periphery of the protrusion 36, and a screw 34 is connected to the internal thread of the nut 33, and the screw 34 extends to the top of the protrusion 36.

[0040] It can be understood that the protrusion 36 and the second connecting plate 35 are formed as one piece, which is convenient for processing and the overall structure is stable and firm.

[0041] Exemplarily, the nut 33 and the protrusion 36 are welded into a whole by a fillet weld, so that the nut 33 is relatively fixed in the entire fastening mechanism 3 .

[0042] It can be understood that the second end is arranged opposite to the protrusion 36. When in use, the second end can be lifted by screwing the screw 34 upward. Since the pressure plate 32 is rotatably connected to the second connecting plate 35, when the second end is lifted, the first end rotates downward to press the arc plate unit 81.

[0043] In some embodiments, multiple fastening mechanisms 3 are provided along the length direction of the arc-shaped plate unit 81 to ensure that at least the arc-shaped plate unit 81 near the end and the middle portion is constrained by the fastening mechanisms 3 .

[0044] In some embodiments, the first end is sloped downward.

[0045] It is understandable that the first end is tilted downward so that when the second end is lifted up, the first end can better fasten the arc-shaped plate unit 81 and save more effort.

[0046] In some embodiments, the rotating mechanism includes a first rotating mechanism 4 located in the middle of the bottom of the supporting platform 1 , and at least one liftable second rotating mechanism 5 is provided on each side of the first rotating mechanism.

[0047] See Figure 4In some embodiments, the first rotating mechanism 4 includes a first rotating component and a second rotating component, the first rotating component and the second rotating component are connected by a second rotating shaft 49, the first rotating component includes a first ear plate 44, and a first intermediate plate 43 and a first bottom plate 42 located sequentially above the first ear plate 44, the first ear plate 44, the first intermediate plate 43 and the first bottom plate 42 are connected by a second bolt 41, and the first bottom plate 42 is fixed on the supporting platform 1; the second rotating component includes a second ear plate 45, and a second intermediate plate 46 and a second bottom plate 47 located sequentially below the second ear plate 45, the second ear plate 45, the second intermediate plate 46 and the second bottom plate 47 are connected by a third bolt 48, and the first ear plate 44 and the second ear plate 45 are connected by a second rotating shaft 49.

[0048] It can be understood that the first bottom plate 42 and the bottom side of the cross beam 11 of the support platform 1 are welded by circumferential fillet welds.

[0049] For example, a second rotating mechanism 5 is provided on both sides of the first rotating mechanism 4 .

[0050] See Figure 6 and Figure 7 In some embodiments, a first support 6 is provided at the bottom of the second bottom plate 47 , and a base plate 7 is provided at the lower portion of the first support 6 .

[0051] In some embodiments, the first support 6 includes a left-right symmetrical column 63, a third connecting plate 61 is provided on the top of the column 63, the bottom of the column 63 is fixed to the base plate 7, and a plurality of stiffening rods 64 are provided between the column 63 between the base plate 7 and the third connecting plate 61, and a stiffening rib 62 is also provided on the column 63 at the bottom of the third connecting plate 61.

[0052] Exemplarily, the upright column 63 and the base plate 7 are fixed by welding.

[0053] See Figure 5 and Figure 8 In some embodiments, the second rotating mechanism 5 includes a third ear plate 53, and a third intermediate plate 52 and a third bottom plate 51 located on the upper part of the third ear plate 53 in sequence, the third ear plate 53, the third intermediate plate 52 and the third bottom plate 51 are connected by a fourth bolt 56, and the third bottom plate 51 is fixed on the support platform 1; the second rotating mechanism 5 also includes a connecting rod 55, and the connecting rod 55 is connected to the third ear plate 53 through a third rotating shaft 54; a hydraulic structure is provided at the bottom of the connecting rod 55, and a second support is provided at the bottom of the hydraulic structure, and the second support is fixed on the base plate 7.

[0054] See also Figure 9 , the embodiment of the present application provides an arc-shaped plate unit 81, including: The plate is arc-shaped and has an inner side surface; Plate ribs a82, arranged sequentially on the inner side surface of the plate along the length direction of the plate; The plate connecting member has a first side and a second side, wherein the first side is provided with a first groove that matches the plate rib a82.

[0055] It can be understood that due to the existence of the arc shape of the plate, there is an angular relationship between the plate ribs a82, and the spacing between the plate ribs a82 tends to decrease from the root to the free end, and the reduction value is directly proportional to the radius of the arc plate.

[0056] In some embodiments, the plate rib a82 and the first groove are fixed by welding.

[0057] Furthermore, the plate rib a82 and the first groove are connected by single-sided welding.

[0058] The embodiment of the present application further provides a method for manufacturing the arc-shaped plate unit 81 , which can be used to manufacture the arc-shaped plate unit 81 of the aforementioned embodiment.

[0059] See also Figure 9 , Figure 10 and Figure 11 In some embodiments, the manufacturing method includes: S01, provide panels; S02. Draw a horizontal baseline 84, a vertical baseline 85, a plate rib position line 87, a plate joint position line, and an arc bending guide line 83 on the plate; S03, pressing the plate into a curved plate along the curved bending guide line 83; S04. Weld the plate rib a82 according to the plate rib position line 87.

[0060] In order to ensure the size and accuracy of the bevel around the arc plate, the present application adopts the method of cutting the plate with the net size + process quantity when cutting the plate, and changes the post-cutting process of the plate unit production; when marking the plate, a high-precision laser marking machine is used to replace manual marking to improve the marking accuracy; the marking type is based on the horizontal baseline 84, the vertical baseline 85, the plate rib position line 87 and the plate joint position line, and the arc bending guide line 83 is added to assist the arc plate profiling and profiling position inspection; in order to improve the assembly accuracy of the plate rib a82, the original plate rib position line 87 is marked according to the plate thickness center line of the plate rib a82 , adjusted to mark the plate skin line on one side or both sides of the plate rib a82, reducing the assembly alignment deviation of the plate rib a82, and realizing one-side reference control or two-way control; the traditional plate unit can measure the vertical relationship between the plate rib a82 and the panel by a protractor, and the present application adopts a single-sided limit assembly device for the arc plate design to control the angle of the plate rib a82, so as to realize the centripetal (center of the circle) assembly of each plate rib a82; the flatness of the traditional plate unit panel can be detected and controlled by a long plate ruler, and the present invention adopts internal and external double-sided templates for the arc surface design to assist in checking the curvature effect, providing an intuitive basis for the correction of the plate unit. The present application mainly realizes the production precision control of the multi-curvature combined arc plate unit 81 from the aspects of curvature control, plate rib a82 spacing and angle, and welding deformation.

[0061] In the S01: In some embodiments, the plate is a rectangular parallelepiped structure.

[0062] Furthermore, the plate is a steel plate.

[0063] In some embodiments, the flatness of the plate surface is ≤1 mm / m.

[0064] In some embodiments, the straightness of the plate edge is ≤1 mm / m.

[0065] In some embodiments, the plate is first milled straight around its periphery, and then grooves are machined around the periphery of the plate.

[0066] It can be understood that the plate is milled straight all around to ensure that the straightness of all sides of the plate is ≤1mm / m. At a distance of 50mm from the edge of the plate, the groove processing alignment line is drawn to accurately locate the position of the processing head or cutting nozzle. According to the processing groove size, such as 45° single V groove or 40° single V groove, the corresponding groove size is processed by adjusting the cutting head angle, thereby realizing groove processing accuracy control and avoiding grooves of different depths and sizes that affect welding quality.

[0067] In the S02: See Figure 2 In some embodiments, a high-precision laser marking machine is used to mark the horizontal baseline 84, the vertical baseline 85, the plate rib position line 87, the plate joint position line and the arc bending guide line 83 on the plate.

[0068] It can be understood that the horizontal baseline 84 and the vertical baseline 85 will be preserved as the benchmark of the unit element until the overall assembly of the steel box girder segment. The vertical and horizontal control of the plate unit manufacturing process is based on the horizontal baseline 84 and the vertical baseline 85. When the steel box girder segment is assembled, the spacing between the horizontal baseline 84 and the vertical baseline 85 of the adjacent plate elements is used to control the plate assembly position, assist in the positioning of the plate unit, and realize the assembly size accuracy control of the steel box girder at the same time.

[0069] In some embodiments, the longitudinal base line 85 is located at the center of the panel along the length of the panel.

[0070] In some embodiments, along the width direction of the plate, the transverse base line 84 is located at the center of the plate or at one side of the center of the plate.

[0071] In some embodiments, a plurality of the plate rib position lines 87 are sequentially spaced apart along the length direction of the plate.

[0072] In some embodiments, a plurality of the plate connecting position lines are sequentially spaced apart along the width direction of the plate.

[0073] In some embodiments, the arc-shaped bending guide lines 83 are arranged at equal intervals along the length of the plate, and the distance between adjacent arc-shaped bending guide lines 83 is less than 100 mm, for example, 10 mm, 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, 90 mm, 99 mm, etc. This distance range is conducive to increasing the indentation density.

[0074] It can be understood that the plate is first bent through the arc-shaped bending guide line 83 and then the plate rib a82 is installed through the plate rib position line 87.

[0075] In said S03: See Figure 1 、 Figure 3 and Figure 4 In some embodiments, a press is used to press the plate along the arc bending guide line 83 into an arc-shaped plate.

[0076] Furthermore, the press includes an upper die and a lower die, the upper die adopts an R150 die head, and the upper die and the lower die cooperate to complete the pressing.

[0077] It can be understood that during the pressing process, the indentation density is increased by encrypting the arc guide lines, and the pressure areas of the plate are cross-propelled to avoid hard bends or obvious straight sections on the plate surface during the bending process.

[0078] Furthermore, during the pressing process, a positioning inspection template is used to track and inspect the arc size after each pressing. If the arc size does not meet the requirements, the press is used to re-press until the arc size meets the requirements.

[0079] It can be understood that each embossing is the arc formed by each plate pressed down by the press.

[0080] It can be understood that the inspection reference edge of the arc inspection template is designed according to the radius size of the arc plate to be inspected. During the inspection process, the inspection reference edge is placed close to the inner skin of the arc plate to check the gap between the template reference edge and the inner skin of the arc plate. When the gap is ≤1mm, it can be determined that the arc pressing size at that location meets the requirements. When the gap is greater than 1mm, it can be determined to be unqualified. During the inspection process, the template position is moved and the arc size of any position of the arc plate is checked multiple times. If it does not meet the requirements, re-pressing is performed. Generally, each position is pressed at least twice.

[0081] In some embodiments, when the curved plate is pressed, a reverse deformation amount is preset.

[0082] It can be understood that the amount of reverse deformation is set according to the chord length of the arc plate + 1mm~2mm, and the production process is adjusted in time according to the actual measurement situation.

[0083] It can be understood that after the arc plate is pressed and formed, the plate rib a82 will continue to be assembled and welded. At the same time, flame correction is required to reduce the influence of welding deformation on the dimensional accuracy of the arc plate unit 81. Therefore, when the arc plate is pressed, it is necessary to preset the reverse deformation amount according to the arc radius of the pressed arc plate and the thickness of the plate. Since the plate ribs a82 are evenly arranged on the inner side of the arc plate, the arc plate will tend to retract due to the heat on the inner side during welding, that is, the arc opening will shrink. Therefore, during the pressing process of the arc plate, the opening size of the arc plate should be appropriately relaxed to compensate for the rebound amount of the steel plate pressing and the welding shrinkage. Here, the reverse deformation amount should be remeasured and tracked during the production process and adjusted when necessary.

[0084] It can also be understood that during the arc-shaped plate pressing process, the arc-pressing and pushing operation of the arc-shaped plate is completed by the CNC front pushing shaft and CNC rear stop frame of the press, realizing the forward pushing and backward feeding (CNC) operation, ensuring that each line is accurate, ensuring that the inner and outer arcs of the arc-shaped plate are smooth, and using a non-indentation lower die to press to ensure that there is no obvious indentation on the outer arc.

[0085] In said S04: See Figure 5 In some embodiments, the plate skin line on one side or both sides of the plate rib a82 is extended into the curved plate to form a plate rib position line 87.

[0086] It can be understood that along the length direction of the arc-shaped plate, plate rib position lines 87 are drawn, and each plate rib position line 87 is connected to the plate skin line on one side or both sides of the corresponding plate rib a82.

[0087] Furthermore, the plate skin of the plate rib a82 is in contact with the plate rib position line 87, and the plate thickness surface of the plate rib a82 is in contact with the inner side surface of the arc-shaped plate.

[0088] It can be understood that the plate skin is the plate thickness surface of the plate rib a82.

[0089] Furthermore, after welding, a positioning inspection template is used to inspect the assembly effect of the plate rib a82.

[0090] It can be understood that spot welding is used for welding, and the positions of the plate rib a82 port and the connecting plate parts are avoided during spot welding, because patch welding is required later.

[0091] Furthermore, the positioning inspection template includes a first side and a second side that are relatively arranged. The first side is provided with a second groove that matches the cross-section of the plate rib a82. The opening of the second groove is located on the first side, and the second groove extends along one side toward the second side. The number of second grooves is the same as the number of plate ribs a82. One side of the second groove is the plate rib reference edge 810, and the first side is the inner arc reference edge 89 and is arc-shaped. The inner arc reference edge 89 matches the inner curved surface of the arc plate; at least one oblong hand hole 812 is provided on the side close to the second side, and a weight reduction hole 811 is also provided on the positioning inspection template between the second grooves.

[0092] Furthermore, the inclination of each plate rib reference edge 810 is different, and the other side of the second groove is inclined away from the side corresponding to the plate rib reference edge 810 so as to fit with the corresponding plate rib a82.

[0093] The inclination of each plate rib reference edge 810 in the present application is different, the purpose of which is to facilitate the fit with the corresponding plate rib a82, and to judge whether the assembly angle of the plate rib a82 is in place by whether there is a gap between the plate rib reference edge 810 and the plate rib a82; the other side of the second groove is inclined away from the side corresponding to the plate rib reference edge 810, the purpose of which is to facilitate the placement of the positioning inspection template in place (to facilitate the fit with the corresponding plate rib a82), and also reduce the net area of ​​the positioning inspection template, which can reduce the weight of the positioning inspection template and facilitate the holding operation during use.

[0094] The arc-shaped plate of the present application is a multi-curvature arc-shaped plate, and its curvature can be changed freely; the plate rib a82 is a plate-shaped structure.

[0095] In some embodiments, the inclination direction of each plate rib a82 is different.

[0096] Exemplarily, the curved plate is a circular arc plate.

[0097] It can be understood that the weight-reducing holes 811 can be of regular shape or irregular shape.

[0098] Furthermore, the second groove of the positioning inspection template is matched with the corresponding plate rib a82, and the inner arc reference edge 89 is matched with the inner curved surface of the arc plate. Then, multiple plate rib reference edges 810 are simultaneously pressed against the plate skin of the plate rib a82 to check the degree of fit between each plate rib a82 surface and the plate rib reference edge 810. If it is not perfectly fitted, adjust it to be perfectly fitted and then perform spot welding to fix it, and release the initial spot welding position at the same time; after the plate rib a82 is spot welded, the plate rib assembly effect of the arc plate along the length direction is checked by moving the positioning inspection template, and the focus should be on controlling the root position of the plate rib a82, the angle of the plate rib a82 and the free end spacing of the plate rib a82. The inspection process must always ensure that the inner arc reference edge 89 and the plate rib reference edge 810 are perfectly fitted to complete the plate rib a82 welding operation.

[0099] It can be understood that the plate surface of the plate rib a82 is the surface on both sides of the width direction of the plate rib a82.

[0100] It can be understood that the focus should be on controlling the root position of the plate rib a82, that is, the outer skin lines on both sides of the plate rib a82 are accurately aligned with the position line of the plate rib a82, where the root position of the plate rib a82 is the position where the outer skin line of the plate rib a82 contacts the inner arc surface of the arc plate, and the welding is to weld both sides of the thickness surface of the plate rib a82.

[0101] It can also be understood that the angle of plate rib a82 and the distance between the free ends of plate rib a82 are because plate rib a82 is welded to the inner side of the curved panel and the plate ribs a82 are arranged centripetally, so a natural angle is formed between the plate ribs a82, that is, the angle of plate rib a82. At the free end of plate rib a82, that is, the width side that is not welded, there will be a size between plate ribs a82 and plate ribs a82, that is, the distance between the free ends of plate ribs a82.

[0102] It can be understood that with the help of positioning inspection template auxiliary control, the centripetal (arc plate center) arrangement of the plate rib a82 is achieved.

[0103] It can be understood that the plate-jointing component position line is used for the later installation of the plate-jointing component.
