The adjustable profiling tire composed of the transverse ribs realizes the bending and twisting shape of the bottom of the main plate of the plate unit;

[0021] Step 6. Finally, carry out manual bending and twisting wall panel welding and pre-assembly of tower segments.

[0022] Compared with the prior art, the present invention has at least the following beneficial effects:

[0023] In the above scheme, the steel plate is flattened by the flattening machine and the pretreatment production line, and then enters the pretreatment production line after the pretreatment is completed. The second flattening operation is carried out after the pretreatment is completed, and the steel plate is put into production after flattening. The two flattening operations can accurately control the flatness of the steel plate to ±0.7mm. Subsequently, AutoPOL and RootExpand software are used to simulate the expansion of bending and torsion parts, set the program, and use a flame CNC cutting machine for cutting. At the same time, the horizontal and vertical ribs are precisely cut and then flattened. Some of the cutting needs to be carried out separately by CNC flame cutting machine and air plasma cutting machine. The time cost of opening the operation is high. By using CNC flame and air plasma cutting components, the two cutting machines can be operated simultaneously or used separately in the same position. The operation control of the plasma cutting pen and the CNC flame cutting pen is connected to the CNC flame and air plasma controller, and the operation control of the marking pen is connected to the marking controller.

[0053] like Figures 1 to 17 As shown, the process steps for manufacturing the cable tower bending and twisting wall panel are:

[0054] Step 1: Steel plate bending and twisting. In view of the characteristics of large number of bent and twisted steel plates, large thickness, and inconsistent shapes, a mobile rotary pressure head frame hydraulic press was specially developed. The machine has an independent power mechanism and electrical system, and adopts centralized button control, which can realize two operation modes: inching and single operation. The CNC system is controlled by the industrial computer PLC, and the screen can dynamically display equipment operation data such as pressure, displacement, valve action, motor forward and reverse rotation, and the working process. It can also perform fault analysis and alarm for pressure, displacement, hydraulic pressure, temperature, etc., and can automatically calculate and store data according to needs;

[0055] Step 2: The steps of making the profiling tire frame are as follows: the adjustable profiling tire is composed of transverse ribs and longitudinal ribs. The transverse ribs are set at the bending line and the two end heads of the plate unit. The top elevation value of the two end heads of each transverse rib is calculated through the corresponding coordinate data in the construction drawing. The adjustable profiling tire composed of transverse ribs realizes the bending and torsion shape of the bottom of the main board of the plate unit; in order to maintain the stability of the tire shape, longitudinal ribs can be set for connection and reinforcement, and the wall panel shape can be flame-corrected. According to the finite element principle, as long as the wall panel and the tire frame ribs are tightly fitted, it can be confirmed The correctness of the wall panel shape, the transverse ribs can be adjusted according to the coordinates, and after disassembly, they can be reused on the plate unit frame of other coordinates, assembled on the profiling tire, so that the wall panel and the frame ribs are closely fitted. The transverse and longitudinal ribs are positioned and assembled on the profiling tire by the transverse and longitudinal rib lines, and then assembled, welded and trimmed. The arc template is used to check the forming condition, and the inspection is carried out at the same time as the pressing. The wall panel shape is flame-corrected to ensure that the wall panel and the frame ribs are closely fitted. The total station is used to measure 6 observation points at different heights, and the deviation of the calibration point is controlled to be ≤5mm;

[0056] Step 3: Assembly and welding of wall panel units, assembly and welding of curved wall panels: Place the outer wall panels on the frame, and the brief process flow is as follows: 1) Position the center outer wall panel unit, starting from the reference segment of each round, place the center bottom plate unit on the frame, and accurately align the horizontal and vertical baselines with the ground sample marking lines. 2) Position the other outer wall panel units on both sides in turn, and symmetrically weld the bottom plate panels on both sides in turn. During assembly, the width is accurately reserved for welding shrinkage. 3) Position the center side inner wall panel unit, set temporary support on the inner side of the inner wall panel during positioning, and set positioning tires on the outside to ensure the curvature of the inner wall panel. After positioning is completed, assemble horizontal and vertical angle steels and tie steel bars. 4) Position the inner wall panel units on both sides in turn, and use the outer tire to detect the curvature of the wall panel during positioning. After passing the test, weld the angle steels and tie 9 steel bars in turn.

[0057] In this embodiment, the key technological points of the straight section wall panels, steel beam webs and top and bottom panels of the shell are: a secondary cutting allowance of 25 mm is reserved in length, precision cutting is performed, and a groove is cut out at the same time, the grooves are on the same surface, marking is performed, and the slope is milled with the groove end as the reference (when available), the slope and the groove are not on the same surface, and the quality requirements are: the width allows a deviation of ±2.0 and the length requires a positive tolerance. The key technological points of the curved wall panels of the shell are: CNC precise cutting, welding shrinkage is reserved according to the thickness in different length directions, and the periphery, manholes, pipeline holes and slot grooves are flame cut (when available). The quality requirements are: the width allows a deviation of ±2.0 (leaving a secondary cutting allowance for the plate unit connected to the curved wall panel) and the length requires a positive tolerance.

[0058] A method for manufacturing and high-precision controlling a steel-concrete composite cable tower bending-torsion wall plate comprises the following steps when used:

[0059] Step 1: Flattening of the steel plate. The steel plate enters the pretreatment production line after being flattened by the flattening machine. After the pretreatment is completed, the second flattening operation is carried out and the steel plate is put into production after flattening. The two flattening operations can accurately control the flatness of the steel plate to ±0.7mm.

[0060] Step 2: Cutting of steel plates: Use AutoPOL and RootExpand software to simulate the expansion of bending and torsion parts, set the program, and use a flame CNC cutting machine to cut and mark at the same time. After the transverse and longitudinal ribs are cut and leveled,

[0061] Step 3: The horizontal and vertical rib positioning lines are marked on the side of the stiffening ribs using the automatic marking reference head of the flame CNC cutting machine as the reference for steel plate forming control and horizontal and vertical stiffening rib assembly;

[0062] Step 4: Steel plate bending and twisting. In view of the characteristics of large number of bent and twisted steel plates, large thickness, and inconsistent shapes, a mobile rotary pressure head frame hydraulic press is used. The machine has an independent power mechanism and electrical system, and adopts button centralized control, which can realize two operation modes: inching and single operation.

[0063] Step 5: Make a profiling tire frame. The adjustable profiling tire is composed of transverse ribs and longitudinal ribs. The transverse ribs are set at the bending line and the two end heads of the plate unit. The top surface elevation value of the two end heads of each transverse rib is calculated according to the corresponding coordinate data in the construction drawing. The adjustable profiling tire composed of the transverse ribs realizes the bending and twisting shape of the bottom of the main plate of the plate unit;

[0064] Step 6. Finally, carry out manual bending and twisting wall panel welding and pre-assembly of tower segments.

[0065] The working principle provided by the present invention is that first, the steel plate is leveled by the leveling machine and the pretreatment production line, and then enters the pretreatment production line. After the pretreatment is completed, a second leveling operation is performed, and the steel plate is put into production after leveling. The two leveling operations can accurately control the flatness of the steel plate to ±0.7mm. Subsequently, AutoPOL and RootExpand software are used to simulate the expansion of bending and torsion parts, set the program, and use a flame CNC cutting machine for cutting and marking at the same time. After the horizontal and vertical ribs are precisely cut and blanked, leveling is performed. Some of the cutting needs to be performed separately by a CNC flame cutting machine and an air plasma cutting machine. The time cost of separate operations is high. The CNC flame and air plasma cutting assembly 6 can be used to operate the two cutting machines simultaneously or separately at the same position, wherein the operation control of the plasma cutting pen 607 and the CNC flame cutting pen 612 It is connected to the CNC flame and air plasma controller 409, and the operation control of the marking pen 610 is connected to the marking controller 410. Combining the CNC flame cutting machine and the air plasma cutting machine can reduce a lot of operation time and diversify the operation. The horizontal and vertical rib positioning lines are marked on the side of the stiffening rib based on the automatic marking reference head of the flame CNC cutting machine, so as to facilitate the steel plate forming control and the assembly of the horizontal and vertical stiffening ribs. Then, some steel plate rust inhibitors are placed inside the liquid medicine tank 303 in the steel plate pretreatment production line component 2, and clean water is placed inside the water tank 306. Water pumps are used on both sides to draw water upward at the same time, and sprayed on the left and right sides of the nozzle 309 respectively to rinse the surface of the steel plate passing through the bottom. After rinsing, the water stains on the surface are wiped off by the drying roller 311, and then subsequent strong light drying is carried out. Two processes are required to complete the cleaning of the upper and lower surfaces of the steel plate.
