Detailed Implementation

[0018] The attached figure illustrates a specific embodiment of the present invention. This embodiment includes an upper working roller system 5, a lower working roller system 6, an upper movable beam 9, a lower movable beam 11, an upper hydraulic cylinder 10, a lower hydraulic cylinder 12, a column 1, and a tie rod 4. The upper working roller system 5 and the lower working roller system 6 are components that directly apply deformation force to the profile 37 to achieve leveling of the profile 37. The upper working roller system 5 consists of five sets of upper monotonic rollers, and the lower working roller system 6 consists of five sets of lower monotonic rollers. The five sets of upper monotonic rollers are respectively connected to the five upper movable beams 9 above them, and the five sets of lower monotonic rollers are respectively connected to the five lower movable beams 11 below them. The five upper movable beams 9 are individually adjusted up and down by the upper hydraulic cylinders 10 above them, thereby adjusting the position of the upper monotonic rollers mounted on them; the five lower movable beams 11 are individually adjusted up and down by the lower hydraulic cylinders 12 below them, thereby adjusting the position of the lower monotonic rollers mounted on them.

[0019] Each upper monotonic roller has four sets of upper rollers 7, and each lower monotonic roller has four sets of lower rollers 8. Each set of upper rollers 7 and each set of lower rollers 8 is equipped with two sets of AC servo motors 23, which can be arbitrarily adjusted along the working roller shaft 13 to adapt to different profile 37 cross-sectional shapes. Six of the ten monotonic rollers are arranged in three pairs vertically coplanarly to improve the lateral (cross-section, perpendicular to the feeding direction) deformation of the profile 37 (see...). Figure 5The upper monotonic roller 1, the upper monotonic roller 2, the upper monotonic roller 3 and the lower monotonic roller 6, the lower monotonic roller 7, the lower monotonic roller 8 are arranged vertically and coplanarly respectively. When the profile is transversely corrected, the profile 37 is transversely corrected by controlling the reduction of the upper monotonic roller 1, the upper monotonic roller 2, the upper monotonic roller 3 relative to the lower monotonic roller 6, the lower monotonic roller 7, the lower monotonic roller 8 respectively, and the number of rollers participating in the correction. Figure 6 The four monotonic rollers are arranged vertically and staggered in the vertical plane (see Figure 5 The upper monotonic roller 4, the upper monotonic roller 5 and the lower monotonic roller 9, the lower monotonic roller 10 are arranged vertically and staggered in the vertical plane, forming a certain roll gap shape, and the profile 37 is longitudinally (along the material running direction) bent to gradually straighten the degree of bending in the roll gap by continuous rotation of the working roller, for improving the longitudinal deformation of the profile 37.

[0020] Each upper monotonic roller is mounted on a separate upper movable beam 9, and each upper movable beam 9 is moved up and down by two (1 set) upper oil cylinders 10 mounted on the upper part of both ends thereof; five upper movable beams 9 are moved up and down individually by five sets of upper oil cylinders 10 respectively. Each lower monotonic roller is mounted on a separate lower movable beam 11, and each lower movable beam 11 is moved up and down by two (1 set) lower oil cylinders 12 mounted on the lower part of both ends thereof; five lower movable beams 11 are moved up and down individually by five sets of lower oil cylinders 12 respectively. The five sets of upper oil cylinders 10 are mounted on the two upper cross beams 2, and the five sets of lower oil cylinders 12 are mounted on the two lower cross beams 3. The upper cross beam 2 and the lower cross beam 3 on the same side of the equipment are connected by two vertical columns 1 to form a closed frame on one side; the two upper cross beams 2, the two lower cross beams 3 and the four vertical columns 1 form two closed frames on the left and right sides. The two closed frames are connected by a pull rod 4 to form a complete equipment frame. The 10 working roller systems adopt single roller driving technology, and each working roller shaft 13 has independent power driving to rotate the working roller shaft 13 and the upper roller 7 or the lower roller 8 mounted on the working roller shaft 13 along the axis thereof, ensuring continuous rolling of the profile 37 during the correction process.

[0021] The upper single roller is composed of a speed reduction motor 16, a speed reduction machine base 17, a working roller shaft 13, a guide key 28, a bearing base 15, a balance base 18, a self-aligning bearing 14, a bearing gland 38 and an upper roller 7. The working roller shaft 13 is installed on the bearing base 15 through the self-aligning bearing 14, and the bearing base 15 is connected to the upper movable beam 9 through screws. The speed reduction motor 16 is installed on the balance base 18 through the speed reduction machine base 17, and the speed reduction motor 16 is connected to the working roller shaft 13 through a spline to drive the working roller shaft 13 to rotate. The working roller shaft 13 is connected to the balance base 18 through the self-aligning bearing 14, and the balance base 18 is connected to the upper movable beam 9 through screws. During the replacement of the upper roller 7, the bearing base 15 away from the balance base 18 is removed, and then the four upper rollers 7 are removed in sequence. At this time, the balance base 18 and the bearing base 15 close to the balance base 18 cooperate to provide support for the working roller shaft 13, so as to ensure that the position of the working roller shaft 13 does not change, so as to facilitate the reinstallation of the upper roller 7 after the later trimming. The bearing gland 38 is used to position the self-aligning bearing 14, and the guide key 28 is installed in the key groove processed on the working roller shaft 13.

[0022] The lower single roller is installed on the lower movable beam 11, and has the same structure and working principle as the above-mentioned upper single roller.

[0023] The driving wheel sleeve 19 is installed on the working roller shaft 13, and a key groove 27 is formed in the inner hole of the driving wheel sleeve 19, which is matched with the guide key 28 installed on the working roller shaft 13, so that the driving wheel sleeve 19 can slide along the working roller shaft 13 in the axial direction. An outer spline is formed on the outer circle of the driving wheel sleeve 19, which is matched with the inner spline on the upper roller 7 or the lower roller 8, so that the upper roller 7 or the lower roller 8 rotates around the axis of the working roller shaft 13 following the driving wheel sleeve 19. Each group of upper rollers 7 or lower rollers 8 and driving wheel sleeves 19 are connected by annular connecting plates 30 distributed uniformly along the circumference, so as to avoid the upper rollers 7 or the lower rollers 8 from moving out of the driving wheel sleeves 19. The material of the upper rollers 7 and the lower rollers 8 is nylon, which can avoid scratching the profiled material 37 during the correction process. The wheels are consumable parts, and the replacement process does not need to disassemble the rollers. The annular connecting plates 30 are connected to the upper rollers 7 or the lower rollers 8 and the driving wheel sleeves 19 respectively through screws. The driving wheel sleeve 19 is installed on the sliding bearing seat 20 through the bearing 29, and the upper part (or the bottom part) of the sliding bearing seat 20 is processed with a guide block 21, which is installed in the guide groove 22 on the bottom (or the top) of the upper movable beam 9 (or the lower movable beam 11). The sliding bearing seat 20 is adjusted in position along the axis of the working roller shaft 13 through the guide groove 22. The top surface (or the bottom surface) of the sliding bearing seat 20 is in contact with the working surface of the upper movable beam 9 (or the lower movable beam 11), and the correction force borne by the upper roller 7 or the lower roller 8 is transmitted to the upper movable beam 9 (or the lower movable beam 11) through the sliding bearing seat 20, so as to avoid the deformation of the working roller shaft 13 due to stress. The AC servo motor 23 is installed on the sliding bearing seat 20, and the sliding gear 24 is installed on the output shaft of the AC servo motor 23, which is engaged with the rack 25 fixed on the upper movable beam 9 (or the lower movable beam 11). The sliding gear 24 is driven to rotate by the AC servo motor 23, which drives the sliding bearing seat 20 to move along the axial direction of the working roller shaft 13, so as to realize the position adjustment of the upper roller 7 or the lower roller 8 along the axial direction of the working roller shaft 13. In order to ensure the smooth movement of the sliding bearing seat 20, two AC servo motors 23 are installed at both ends of each sliding bearing seat 20, which drive two sliding gears 24 to move in engagement with the two racks 25 on the two end surfaces of the upper movable beam 9 (or the lower movable beam 11). The sliding bearing seat 20 is installed on the upper movable beam 9 (or the lower movable beam 11) through the screws of the pressing plate 26. The sliding pads 31 (self-lubricating pads) are installed between the pressing plate 26 and the guide groove 22, between the guide groove 22 and the guide block 21, and between the working surface of the sliding bearing seat 20 and the upper movable beam 9 (or the lower movable beam 11), which are used to reduce the frictional force of the sliding bearing seat 20 and reduce energy consumption.

[0024] The middle position of the upper working surface of the upper movable beam 9 is machined with a guide groove 22 along the axis of the work roll shaft 13 to guide the movement of the upper roll 7. The two sides of the lower working surface are installed with a rack 25 to cooperate with a sliding gear 24 to realize the movement of the upper roll 7. The upper part of the two ends of the upper movable beam 9 is machined with a shoulder 32 for installing the upper oil cylinder 10, and the shoulder 32 has two. The vertical direction between the two upper movable beams 9 and the vertical direction between the upper movable beam 9 and the column 1 are both installed with a guide rail plate 36 to guide the up and down movement of the upper movable beam 9.

[0025] The upper oil cylinder 10 is five groups, installed on the two upper cross beams 2, each group of the upper oil cylinder 10 is two, the piston rod (the head is machined with a clamping groove) of the same group of the upper oil cylinder 10 is connected with the two shoulders 32 of the upper movable beam 9 through the clamping sleeve 33 installed in the clamping groove, and the spherical pad 34 is placed between the piston rod of the upper oil cylinder 10 and the shoulder 32. The connection between the clamping sleeve 33 and the shoulder 32 is realized by screws. The extension and retraction of the piston rod of each group of the upper oil cylinder 10 is synchronously controlled to realize the independent adjustment of the position of each upper movable beam 9, thereby realizing the position adjustment of the upper work roll system 5.

[0026] The upper cross beam 2 is machined with a circular stop for installing the upper oil cylinder 10, and the cavity of the upper oil cylinder 10 is placed into the upper cross beam 2. The lower movable beam 11 has the same structure as the upper movable beam 9, which is an inverted structure of the upper movable beam 9, the working surface is located at the upper part, and the shoulder 32 is located at the lower part.

[0027] In order to realize that six of the ten single rolls are arranged in three pairs of vertical coplanar, and four single rolls are arranged in vertical plane up and down staggered, a lower fixed beam 35 is installed between the third lower movable beam 11 and the fourth lower movable beam 11, and the bottom surface of the lower fixed beam 35 is screwed to the two lower cross beams 3. The position of the lower fixed beam 35 is fixed, and it is only used to realize the position staggering of the two lower single rolls and the upper single rolls.

[0028] The vertical direction between the two lower movable beams 11, the vertical direction between the lower movable beam 11 and the column 1, and the vertical direction between the lower movable beam 11 and the lower fixed beam 35 are all installed with a guide rail plate 36 to guide the up and down movement of the lower movable beam 11.

[0029] The lower oil cylinder 12 is five groups, installed on the two lower cross beams 3, each group of the lower oil cylinder 12 is two, the piston rod (the head is machined with a clamping groove) of the same group of the lower oil cylinder 12 is connected with the two shoulders 32 of the lower movable beam 11 through the clamping sleeve 33 installed in the clamping groove, and the spherical pad 34 is placed between the piston rod of the lower oil cylinder 12 and the shoulder 32. The connection between the clamping sleeve 33 and the shoulder 32 is realized by screws. The extension and retraction of the piston rod of each group of the lower oil cylinder 12 is synchronously controlled to realize the independent adjustment of the position of each lower movable beam 11, thereby realizing the position adjustment of the lower work roll system 6.

[0030] The wide long plate type complex section profile multi-point flexible straightening machine uses 10 parallel roller shafts (5 upper rollers and 5 lower rollers) which can be separately adjusted in height position and arranged in up-down opposite top and staggered mode to drive four groups of roller wheels arranged on each roller shaft to continuously rotate, the position of the roller wheels can be automatically adjusted along the axis, longitudinal and transverse two direction reverse bending deformation forces are applied to different section shape profiles, the straightening of the different section shape profiles in longitudinal and transverse two directions is realized, the straightening precision is high, the efficiency is high, and the application range is wide.
