The conveying mechanism may mainly include a first roller 21 and a second roller 22. The straightening mechanism 3 mainly comprises a support plate 31, a web straightening roller 32, two flange straightening plates 33 and two web straightening plates 34. A horizontal plate 311 is fixed to the stay plate 31, and a vertical plate 312 is fixed to the horizontal plate 311. Both end faces of the web straightening roll 32 are inclined, and the projection of the web straightening roll 32 on a vertical plane is trapezoidal.

The flange straightening plate 33 is connected vertically to the end of the web straightening plate 34 remote from the web straightening roll 32. Straightening mechanisms 3 are arranged on the upper side and the lower side of a web plate 71 of the H-shaped steel 7. The straightening mechanisms 3 located on the lower side of the web 71 of the H-shaped steel 7 are connected to the base 11 through corresponding stays 31, and the straightening mechanisms 3 located on the upper side of the web 71 of the H-shaped steel 7 are connected to the top plate 13 through corresponding stays 31.
As shown in fig. 4 and 5, in order to secure the straightening effect to the web 71, the upper side of the web straightening plate 34 is flush with the top of the side surface of the web straightening roller 32, so that there is no vertical drop at the joint of the upper side of the web straightening plate 34 and the web straightening roller 32 during the rotation of the web straightening roller 32, that is, both the web straightening plate 34 and the web straightening roller 32 can maintain the state of contacting with the web 71 of the H-beam 7 during the rotation of the web straightening roller 32.
The working principle of the H-shaped steel straightening device is as follows:
the H-shaped steel 7 is placed between the first rotating roller 21 and the second rotating roller 22, because two end faces of the web straightening roller 32 are inclined, the web straightening plate 34 is inclined close to the end face of the web straightening roller 32 and is attached to the end face of the web straightening roller 32, and the two web straightening plates 34 can move in opposite directions under the driving of the reset assembly 35, when the web straightening roller 32 continuously rotates in a certain direction, the two web straightening plates 34 can transversely move in a reciprocating manner, so that the two web straightening plates 34 drive the two flange straightening plates 33 to be close to and away from each other, the distance between the two flange straightening plates 33 can be adjusted according to the distance between the two flange straightening plates 72 of the H-shaped steel 7, one side of the flange straightening plate 33 is attached to the flange straightening plates 72, and the straightening effect on the H-shaped steel 7 is guaranteed. After one side of the flange straightening plate 33 is attached to the flange plate 72, the first rotating roller 21 and/or the second rotating roller 22 can be rotated while the rotation of the web straightening roller 32 is restricted, so that the H-section steel 7 can be moved to achieve continuous straightening of the web 71 and the flange plate 72 of the H-section steel 7.
The main components and the working principle of the H-shaped steel straightening device are described above, and the H-shaped steel straightening device is explained in more detail below.
In the present embodiment, the return assembly 35 may mainly include a connection post 351, a first link 352, a second link 353, and a return spring 354. The attachment post 351 is attached to the plate 31. First connecting rod 352 is connected with the spliced pole 351 rotation, and the both ends of first connecting rod 352 all articulate there is first slider 355, and first slider 355 sliding connection is in one side of edge of a wing board 33. Second connecting rod 353 rotates with the spliced pole 351 and is connected, and the both ends of second connecting rod 353 all articulate there is second slider 356, and second slider 356 sliding connection is in one side of edge of a wing board 33. One end of the return spring 354 is connected to the first link 352, and the other end is connected to the second link 353. As the web-straightening roller 32 is continuously rotated in a certain direction, the first link 352 and the second link 353 are moved accordingly. Through the arrangement of the connecting column 351, the first connecting rod 352, the second connecting rod 353 and the return spring 354, the flange straightening plates 33 can be better supported, and the two web straightening plates 34 can be moved oppositely under the action of the return spring 354 after the distance between the two web straightening plates 34 reaches the maximum.
Referring to fig. 4, 6 and 7, since the joint between the flange plate 72 and the web 71 of the H-section steel 7 may have a certain curvature, if it is desired to straighten the joint, it is necessary to improve the structure of the joint between the web straightening plate 34 and the flange straightening plate 33. Specifically, a groove 331 is formed at the joint of the web straightening plate 34 and the flange straightening plate 33, and an adapting block 332 is connected to the groove 331 through a third rotating shaft 336. The side surface of the adapter block 332 is composed of a first adapting surface 333, a second adapting surface 334 and a third adapting surface 335 which are sequentially connected along the clockwise direction. The first fitting surface 333 and the second fitting surface 334 are both flat surfaces and perpendicular to each other, and the third fitting surface 335 is arc-shaped. The third shaft 336 is coaxial with the recess 331. The junctions among the first adapting surface 333, the second adapting surface 334 and the third adapting surface 335 can be abutted against the inner wall of the groove 331. When the connection position of the flange plate 72 and the web plate 71 of the H-shaped steel 7 has a certain radian, the adapter block 332 is rotated first before the H-shaped steel 7 is placed into the H-shaped steel straightening device, so that the first adapter surface 333 and the second adapter surface 334 of the adapter block 332 are positioned in the groove 331, and then the H-shaped steel 7 is placed into the H-shaped steel straightening device, at this time, the third adapter surface 335 can be attached to the connection position of the flange plate 72 and the web plate 71 of the H-shaped steel 7, because the connection position of the flange plate 72 and the web plate 71 of the H-shaped steel 7 is attached to the third adapter surface 335, the adapter block 332 cannot rotate any more under the limitation of the connection position of the flange plate 72 and the web plate 71 of the H-shaped steel 7, and the adapter block 332 can be kept in the above state, so as to straighten the connection position of the flange plate 72 and the web plate 71 of the H-shaped steel 7; when the joint of the flange plate 72 and the web plate 71 of the H-beam 7 is a right angle, before the H-beam 7 is placed into the H-beam straightening device, the adapter block 332 is rotated first to enable the third adapter surface 335 of the adapter block 332 to be located in the groove 331, and then the H-beam 7 is placed into the H-beam straightening device, at this time, the first adapter surface 333 can be attached to the web plate 71 of the H-beam 7, the second adapter surface 334 can be attached to the flange plate 72, under the limitation of the flange plate 72 and the web plate 71 of the H-beam 7, the adapter block 332 cannot rotate any more, and the adapter block 332 can be kept in the above state, so as to better straighten the flange plate 72 and the web plate 71 of the H-beam 7.
The first rotary roller 21 is mounted on the base 11 through a first roller frame 211, and the second rotary roller 22 is mounted on the base 11 through a second roller frame 221. The first roller 21 is connected with a driving motor 212 in a transmission way. The second roller 22 is connected with an adjusting seat 222, the adjusting seat 222 is connected with a screw 223 in a threaded manner, and the screw 223 is connected with an adjusting motor 224 in a transmission manner. When the adjusting motor 224 works, the adjusting base 222 can drive the second rotating roller 22 to move transversely, so that the distance between the first rotating roller 21 and the second rotating roller 22 can be adjusted according to the size of the H-shaped steel 7, and the purpose of better straightening the H-shaped steel 7 is achieved.
The vertical plate 12 is inserted with the top plate 13. A lifting cylinder 14 is arranged on the vertical plate 12, and the movable end of the lifting cylinder 14 is connected with the top plate 13. Under the action of the lifting cylinder 14, the top plate 13 can drive the straightening mechanism 3 located on the upper side of the web 71 of the H-shaped steel 7 to move upwards or downwards, so that the distance between the top plate 13 and the base 11 can be adjusted according to the size of the H-shaped steel 7, and the purpose of better straightening the H-shaped steel 7 is achieved.
To facilitate rotating the web straightening rolls 32, the H-section straightener may also include a drive assembly 36. The drive assembly 36 may generally include a drive shaft 361, a drive bevel gear 362, and a driven bevel gear 363. A driving shaft 361 is mounted on the vertical plate 312 through a mounting plate 364, a driving bevel gear 362 is mounted on the driving shaft 361, and a driven bevel gear 363 is mounted on the first rotation shaft 321. By rotating the drive shaft 361, the web straightening rollers 32 can be rotated.
The drive assembly 36 may also include a first rotary motor 365 drivingly connected to the drive shaft 361. The drive shaft 361 is coupled to the mounting plate 364 by a one-way bearing 366. Since the drive shaft 361 can only rotate in one direction and the web straightening roll 32 can only rotate in one direction, the H-section steel 7 can be moved in a direction in which the web straightening roll 32 cannot rotate after the distance between the two flange straightening plates 33 is adjusted, so that the purpose of limiting the rotation of the web straightening roll 32 is achieved without using other equipment.
Example 2
The present embodiment is a further improvement made on the basis of embodiment 1.
Referring to fig. 1-9, the driving assembly 36 may further include a limit pin 461. The limiting pin 461 is inserted into the mounting plate 364. The first shaft 321 has a plurality of pin holes 462 formed along the circumferential direction thereof for matching with the limit pins 461. After moving the stopper pin 461 downward and disengaging the stopper pin 461 from the pin hole 462, the web straightening roller 32 can be rotated so as to adjust the distance between the two flange straightening plates 33. Due to the presence of the stopper pin 461, it is not necessary to restrict the moving direction of the H-section 7 when straightening the H-section 7, and the H-section 7 can be moved left or right (left-right direction shown in FIG. 2).
Example 3

When the plug 571 moves upward, the oil reservoir passage 561, the first conduit 562, the circulation pump 563 and the second conduit 564 form a circulation path. Drive assembly 36 may further include a first toothed plate 575, a reversing gear 576, and a second toothed plate 577, which are in sequential driving communication. The first toothed plate 575 is connected at the upper end of the movable rod 572, the second toothed plate 577 is connected at the lower end of the limit pin 461, and the reversing gear 576 is located between the first toothed plate 575 and the second toothed plate 577.
When the circulating pump 563 works, the hydraulic oil 567 in the oil storage channel 561 flushes the plug 571, so that the plug 571 drives the movable rod 572 to move upwards, when the movable rod 572 moves upwards, the first toothed plate 575 is driven to move upwards, under the reversing action of the reversing gear 576, the second toothed plate 577 drives the limit pin 461 to move downwards, so that the limit pin 461 is separated from the pin hole 462, and after the limit pin 461 is separated from the pin hole 462, the first rotating shaft 321 can rotate, so that the distance between the two flange straightening plates 33 can be adjusted. After the plug 571 is flushed by the hydraulic oil 567, the hydraulic oil enters the first conduit 562, the driving blade 574 in the first conduit 562 drives the driving shaft 361 to rotate under the action of the hydraulic oil 567, and the driving shaft 361 further drives the first rotating shaft 321 to rotate. When the circulating pump 563 stops working, the flow rate of the hydraulic oil 567 is reduced to be completely static, in this process, the plug 571 drives the movable rod 572 to move down and reset to block the communicating hole 569 again, and when the movable rod 572 moves down and resets, the limit pin 461 moves up and is inserted into the pin hole 462 to limit the rotation of the first rotating shaft 321, so as to conveniently straighten the H-shaped steel 7.
