Description

Technical Field

[0001] This invention relates to the technical field of steel structure processing, and in particular to a steel structure processing and straightening machine. Background Technology

[0002] In the field of steel structure manufacturing and engineering applications, shaft-type steel structural components (such as steel columns, long tie rods, struts, etc.) widely undertake axial force functions. During processing, due to factors such as residual stress of raw materials, welding, transportation and installation, these components often undergo bending or local deformation, causing their straightness to exceed the design allowable deviation. Therefore, they need to be straightened.

[0003] Currently, the commonly used straightening method is roller pressing. This method utilizes rollers perpendicular to the conveying direction of the steel structure. During continuous conveying of the steel structure, the rollers apply static rolling pressure to the surface of the component to correct local plastic bending. However, due to the fixed position of the rollers and the single direction of force application, this method can only straighten the deformation area of ​​the steel structure in a specific orientation. For bending deformation at other angles in the circumferential direction of the component, it is difficult to achieve effective correction because the rollers cannot dynamically adjust the direction of force application. This results in significant blind spots in the straightening range. To complete all-round straightening, operators need to adjust the orientation angle of the steel structure multiple times and make it pass through the straightening station repeatedly. Each component usually needs to be straightened multiple times to meet the specified straightness requirements. In addition, the traditional contact between the rollers and shaft-type steel structures is mostly point contact, with a small contact area and concentrated straightening force, which easily forms indentations on the surface of the component, affecting the surface quality. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a steel structure processing and straightening machine, the specific technical solution of which is as follows: The present invention provides a steel structure processing and straightening machine, comprising: barrel; A plurality of rolling units are arranged in a ring on the inner wall of the barrel. A steel component passes through the gap between the rolling units. Each rolling unit includes two drive wheels arranged opposite each other along the conveying direction of the steel component and a drive chain driven on the two drive wheels. A plurality of pressure rollers are arranged on the drive chain. During the operation of the drive wheels and the drive chain, the side of the drive chain near the steel component pushes the pressure rollers along the conveying direction of the steel component, so that the pressure rollers and the steel component are relatively stationary along the conveying direction of the steel component. The axis of the pressure rollers is arranged parallel to the axis of the steel component. During the rotation of the barrel, the pressure roller rolls on the outer wall of the steel component.

[0005] Furthermore, the rolling unit also includes a guide body; When the transmission chain pushes the pressure roller on the side closest to the steel component, the guide body guides the pressure roller, causing the pressure roller to move closer to or away from the steel component.

[0006] Furthermore, the guide body includes a support plate one and a support plate two arranged opposite to each other. Both the support plate one and the support plate two are fixedly arranged relative to the barrel. A closed annular guide groove is provided on the surface of the support plate one facing the support plate two and on the surface of the support plate two facing the support plate one. The directions of the two guide grooves are arranged opposite to each other. The guide groove includes a rotary section, a translational section, and an extrusion section. The translational section is located at one end of the rotary section. The other end of the rotary section and the end of the translational section away from the rotary section are both provided with inclined guide sections. The extrusion section is located between the two guide sections. Both the translational section and the extrusion section are arranged parallel to the steel component conveying direction. In the radial direction of the steel component, the translational section and the extrusion section are staggered. The translation sections on the two guide grooves are positioned opposite each other, and several movable columns are slidably arranged in each guide groove. The two corresponding movable columns on the two guide grooves are connected by a connecting plate, and the connecting plate is connected to the corresponding pressure roller by a connecting arm. The pressure roller is rotatably arranged on the connecting arm.

[0007] Furthermore, the transmission chain is connected to the connecting plate via a push arm, and the end of the push arm passes through the connecting plate and slides into the connecting arm.

[0008] Furthermore, the pressure rollers on the several rolling units are correspondingly arranged, and there are two machine barrels, with the gaps between adjacent pressure rollers on the rolling units in the two machine barrels being staggered. Alternatively, the pressure rollers on several of the rolling units may be staggered.

[0009] Furthermore, the pressure roller includes a core column rotatably mounted on the connecting arm and a rolling cylinder sleeved on the outside of the core column. A plurality of spring plates are provided on the outer wall of the core column. The spring plates slide in contact with the inner wall of the rolling cylinder and provide elastic thrust to the rolling cylinder. A boss is provided on the outer wall of the core column away from the spring plates. The surface of the boss facing the inner wall of the rolling cylinder consists of a shaping arc surface that slides in contact with the inner wall of the rolling cylinder and a guiding arc surface that is eccentrically positioned relative to the axis of the core column. When the guiding arc surface is located between the core column and the steel component, the deformation position on the steel component can push the rolling cylinder away from the core column. When the shaping arc surface is located between the core column and the steel component, the shaping arc surface supports the rolling cylinder, making the rolling cylinder coaxial with the core column.

[0010] Furthermore, a lever is provided at the end of the core column, and the lever is connected to the connecting arm by a spring piece 2, and a limiting protrusion is provided on the connecting arm to limit the lever; The support plate one or the support plate two is provided with a side plate, and the side plate is provided with a slope surface that cooperates with the lever.

[0011] Furthermore, rollers are rotatably provided at the ends of the movable columns on the first support plate away from the first support plate and at the ends of the movable columns on the second support plate away from the second support plate. Guide edges are provided on both the first support plate and the second support plate. The guide edge on the first support plate guides the rollers on the second support plate, and the shape of the guide edge on the first support plate is consistent with the shape of the guide groove on the second support plate. The guide edge on the second support plate guides the rollers on the first support plate, and the shape of the guide edge on the second support plate is consistent with the shape of the guide groove on the first support plate. The guide edge has two notches, allowing the movable column to pass through the notches and move.

[0012] The beneficial effects of this invention are as follows: By utilizing several rolling units that move around the circumference of a steel component, the bending deformation at any position along the circumference of the steel component can be straightened by the pressure rollers on the rolling units. This achieves one-time straightening and forming of the steel component, eliminating the need for repeated straightening. Furthermore, this straightening method is a rolling mode, which reduces the friction between the rolling units and the steel component, increases the force application area on the steel component, and avoids stress concentration and indentation on the surface of the steel component. Since the rolling units can drive several pressure rollers for cyclic conveying and allow the pressure rollers to remain relatively stationary with respect to the steel component along the axial direction of the steel component, relatively static straightening of the steel component can be achieved while ensuring stable and continuous conveying, thus improving work efficiency.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0017] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0018] like Figures 1 to 9 As shown, a steel structure processing and straightening machine of the present invention includes: barrel 1; A plurality of rolling units 2 are arranged in a ring on the inner wall of the barrel 1. The steel component 30 passes through the gap between the plurality of rolling units 2. The rolling unit 2 includes two drive wheels 3 arranged opposite to each other along the conveying direction of the steel component 30 and a drive chain 4 driven on the two drive wheels 3. A plurality of pressure rollers 5 are arranged on the drive chain 4. During the operation of the drive wheels 3 and the drive chain 4, the side of the drive chain 4 close to the steel component 30 pushes the pressure rollers 5 along the conveying direction of the steel component 30, so that the pressure rollers 5 and the steel component 30 are relatively stationary along the conveying direction of the steel component 30. The axis of the pressure rollers 5 is arranged parallel to the axis of the steel component 30. During the rotation of the barrel 1, the pressure roller 5 rolls on the outer wall of the steel component 30.

[0019] Specifically, the axis of the barrel 1 is aligned with the conveying direction of the steel component 30. That is, when the steel component 30 is conveyed laterally, the axis of the barrel 1 is set laterally. When the steel component 30 is conveyed vertically or at an incline, the axis of the barrel 1 is adjusted accordingly. This allows the barrel 1 and its internal structure to meet various processing requirements. Several rolling units 2 are distributed along the circumference of the steel component 30 inside the barrel 1. This allows the rolling units 2 to cooperate with each other to squeeze the steel component 30. When the barrel 1 moves in a circular motion, the rolling units 2 can squeeze and straighten the steel component 30 around its circumference. The operation of the drive wheels 3 on the barrel 1 and rolling units 2 can be powered by an external motor.

[0020] Taking two rolling units 2 inside the barrel 1 as an example, such as Figure 2 As shown, two rolling units 2 are distributed opposite each other on both sides of the axis of the steel component 30. The two rolling units 2 work together to squeeze the steel component 30. The two transmission wheels 3 on the rolling unit 2 can drive the transmission chain 4 to run. When the pressure roller 5 on the transmission chain 4 is close to the steel component 30, the pressure roller 5 moves linearly along the conveying direction of the steel component 30 and the pressure roller 5 and the steel component 30 are relatively stationary along the conveying direction of the steel component 30. On the side away from the steel component 30, the pressure roller 5 moves linearly in the opposite direction to the conveying direction of the steel component 30.

[0021] In use, the drive cylinder 1 and the drive wheel 3 on the rolling unit 2 operate. The cylinder 1 drives several rolling units 2 to move in a circular motion around the steel component 30, and the pressure roller 5 rolls on the outer wall of the steel component 30. Thus, the pressure roller 5 is used to squeeze and straighten the bent position of the steel component 30 in the circumferential direction. At the same time, the drive wheel 3 can drive the drive chain 4 and several pressure rollers 5 on it to move synchronously. The pressure roller 5 on the side of the drive chain 4 closest to the steel component 30 can move synchronously with the steel component 30. At this time, along the conveying direction of the steel component 30, the pressure roller 5 is relatively stationary with the steel component 30. That is, at this time, the pressure roller 5 can roll and straighten the outer circumferential wall of the relatively stationary steel component 30. The linear movement of the pressure roller 5 can keep the steel component 30 in the conveying state, thereby realizing the dynamic straightening function.

[0022] By utilizing several rolling units 2 moving around the circumference of the steel component 30, the bending deformation at any position on the circumference of the steel component 30 can be straightened by the pressure rollers 5 on the rolling units 2, achieving one-time straightening and forming of the steel component 30 without repeated straightening. Moreover, this straightening method is a rolling mode, thereby reducing the friction between the rolling units 2 and the steel component 30, increasing the force application area on the steel component 30, avoiding stress concentration and the formation of indentations on the surface of the steel component 30. Since the rolling units 2 can circulate and transport multiple pressure rollers 5, and the pressure rollers 5 can be relatively stationary with respect to the steel component 30 along the axial direction of the steel component 30, relatively static straightening of the steel component 30 can be achieved while ensuring stable and continuous transport of the steel component 30, thus improving work efficiency.

[0023] Furthermore, the rolling unit 2 also includes a guide body; When the transmission chain 4 pushes the pressure roller 5 on the side closest to the steel component 30, the guide body guides the pressure roller 5, causing the pressure roller 5 to move closer to or away from the steel component 30.

[0024] When the pressure roller 5 moves with the transmission chain 4, at the position on the transmission chain 4 where it coincides with the two transmission wheels 3, the movement trajectory of the pressure roller 5 is arc-shaped. If the pressure roller 5 moves directly in an arc shape at this time, the two ends of the pressure roller 5 are likely to jam with the steel component 30. By using the guide body to guide the pressure roller 5, the pressure roller 5 can have three positions in the relatively stationary range with the steel component 30: the position where the pressure roller 5 is in contact with the steel component 30 and two positions where the pressure roller 5 is away from the steel component 30 but still parallel to each other. The two positions that are away from each other are located on both sides of the contact position, which facilitates the provision of space for the arc-shaped movement of the pressure roller 5.

[0025] Using the above-described structure, when the pressure roller 5 approaches the steel component 30, the pressure roller 5 and the steel component 30 remain parallel to each other. That is, the pressure roller 5 contacts the steel component 30 by moving closer, so that the pressure roller 5 and the steel component 30 can directly form a line contact mode.

[0026] Furthermore, the guide body includes a support plate 6 and a support plate 7 arranged opposite to each other. Both the support plate 6 and the support plate 7 are fixedly arranged relative to the barrel 1. A closed annular guide groove is provided on the surface of the support plate 6 facing the support plate 7 and on the surface of the support plate 7 facing the support plate 6, and the two guide grooves are arranged in opposite directions. The guide channel includes a rotary section 8, a translational section 9, and an extrusion section 10. The translational section 9 is located at one end of the rotary section 8. The other end of the rotary section 8 and the end of the translational section 9 away from the rotary section 8 are both provided with inclined guide sections 11. The extrusion section 10 is located between the two guide sections 11. The translational section 9 and the extrusion section 10 are both arranged parallel to the conveying direction of the steel component 30, and in the radial direction of the steel component 30, the translational section 9 and the extrusion section 10 are staggered. Among them, the translation sections 9 on the two guide grooves are positioned opposite each other, and several movable columns 12 are slidably arranged in each guide groove. The two corresponding movable columns 12 on the two guide grooves are connected by a connecting plate 13, and the connecting plate 13 is connected to the corresponding pressure roller 5 by a connecting arm 14. The pressure roller 5 is rotatably arranged on the connecting arm 14.

[0027] Support plate 6 and support plate 7 are arranged parallel to each other, and both support plate 6 and support plate 7 are fixed to the inner wall of the same cylinder 1. Since the pressure roller 5 moves closer to or further away from the steel component 30 by translation, the structure of the guide groove needs to be specifically limited. Specifically, the relative orientation of the two guide grooves is as follows: Figures 3 to 4 As shown, the translation segment 9 on support plate 16 is located on the right side, and the translation segment 9 on support plate 27 is located on the left side. Part of the extrusion segment 10 on support plate 16 corresponds to the translation segment 9 on support plate 27, and another part corresponds to part of the extrusion segment 10 on support plate 27. Of course, the translation segment 9 on support plate 16 can also be located on the left side, and the translation segment 9 on support plate 27 can be located on the right side, as long as the directions of the two guide grooves are opposite.

[0028] The guide inclined section 11 is mainly used to guide the moving column 12 to transition between the translation section 9, the extrusion section 10 and the rotation section 8. The rotation section 8 is mainly used to guide the moving column 12 to rotate. The extrusion section 10 is closer to the steel component 30 than the translation section 9. The two moving columns 12 at both ends of the connecting plate 13 are respectively set in the two guide grooves, and the transmission chain 4 can drive the pressure roller 5 to move by moving the connecting plate 13.

[0029] When the transmission chain 4 is running, the two moving columns 12 on the connecting plate 13 move in the two guide grooves respectively. When the two moving columns 12 are simultaneously located in the two extrusion sections 10, the pressure roller 5 contacts the steel component 30 and rolls and straightens it. When one moving column 12 moves to the guide inclined section 11 between the corresponding rotary section 8 and the extrusion section 10, the other moving column 12 moves to the guide inclined section 11 between the corresponding extrusion section 10 and the translation section 9. At this time, the two moving columns 12 move synchronously in the direction away from the steel component 30, and the pressure roller 5 remains parallel to the steel component 30. When the two moving columns 12 rotate through the two rotary sections 8 to the two guide inclined sections 11 on the corresponding side of the support plate 1 6 and the support plate 2 7, the pressure roller 5 translates again and approaches the steel component 30, thereby realizing the translational movement mode of the pressure roller 5.

[0030] The above-described structure allows the two moving columns 12 on both sides of the connecting plate 13 to move independently, thereby achieving translational movement of the two moving columns 12, the connecting plate 13, and the pressure roller 5. The structure is simple and requires no manual operation.

[0031] The shape of the rotary section 8 is the same as that of the transmission chain 4.

[0032] Furthermore, the transmission chain 4 is connected to the connecting plate 13 via a push arm 15, and the end of the push arm 15 passes through the connecting plate 13 and slides into the connecting arm 14.

[0033] Since the pressure roller 5 will actively move closer to or further away from the steel component 30 in the radial direction, the distance between the connecting arm 14 and the transmission chain 4 needs to be adjustable. The pushing arm 15 can transmit the pushing force of the transmission chain 4 to the connecting arm 14 and the pressure roller 5. At the same time, the mutual sliding and interlocking mode of the pushing arm 15 and the connecting arm 14 can meet the normal movement requirements of the pressure roller 5.

[0034] Furthermore, the pressure rollers 5 on several rolling units 2 are correspondingly arranged, and there are two cylinders 1, and the gaps between two adjacent pressure rollers 5 on the rolling units 2 in the two cylinders 1 are staggered. Alternatively, the pressure rollers 5 on several rolling units 2 may be staggered.

[0035] When the pressure rollers 5 on the several rolling units 2 inside the barrel 1 are set up in a corresponding manner, the gap between two adjacent pressure rollers 5 on one rolling unit 2 will also appear on other rolling units 2. That is, when several rolling units 2 roll the steel component 30, the area of ​​the steel component 30 corresponding to the gap will have a straightening blind zone. However, by using the arrangement of two barrels 1 and setting the gaps in a staggered manner, the blind zone of the steel component 30 processed by several rolling units 2 in one barrel 1 can be straightened by several rolling units 2 in another barrel 1, thereby eliminating the blind zone.

[0036] When only one cylinder 1 is used, several rolling units 2 inside it can be staggered, that is, the gap on one rolling unit 2 corresponds to the pressure roller 5 on another rolling unit 2. Thus, when several rolling units 2 move around the circumference of the steel component 30, the outer wall of the steel component 30 can be fully rolled and straightened by several pressure rollers 5.

[0037] Furthermore, the pressure roller 5 includes a core column 16 rotatably mounted on the connecting arm 14 and a rolling cylinder 17 sleeved on the outside of the core column 16. A plurality of spring plates 18 are provided on the outer wall of the core column 16. The spring plates 18 slide in contact with the inner wall of the rolling cylinder 17 and provide elastic thrust to the rolling cylinder 17. A boss 19 is provided on the outer wall of the core column 16 away from the spring plates 18. The surface of the boss 19 facing the inner wall of the rolling cylinder 17 is composed of a shaping arc surface 21 that slides in contact with the inner wall of the rolling cylinder 17 and a guide arc surface 20 that is eccentrically arranged with the axis of the core column 16. When the guide arc surface 20 is located between the core column 16 and the steel member 30, the deformation position on the steel member 30 can push the rolling cylinder 17 away from the core column 16. When the shaping arc surface 21 is located between the core column 16 and the steel member 30, the shaping arc surface 21 supports the rolling cylinder 17, so that the rolling cylinder 17 and the core column 16 are coaxially arranged.

[0038] Since the rolling cylinder 17 needs to roll around the outer wall of the steel component 30, the spring piece 18 and the boss 19 only need to slide in contact with the rolling cylinder 17. Of course, in order to improve the connection strength, a slider can be set on the inner wall of the rolling cylinder 17 so that the slider can slide along the circumference of the rolling cylinder 17. The spring piece 18 is connected to the slider. The core column 16 is mainly used to support the rolling cylinder 17 and adjust the position of the boss 19 relative to the rolling cylinder 17.

[0039] The spring plate 18 and the boss 19 are located on both sides of the core column 16. In the natural state, the elastic force provided by the spring plate 18 to the rolling cylinder 17 causes the shaping arc surface 21 on the boss 19 to fit against the inner wall of the rolling cylinder 17. At this time, the rolling cylinder 17 and the core column 16 are coaxial. When the pressure roller 5 rolls the steel component 30, the initial guiding arc surface 20 is located between the core column 16 and the steel component 30. At this time, the protruding area on the steel component 30 can overcome the elastic force of the spring plate 18 and push the axis of the rolling cylinder 17 to move away from the steel component 30 until the inner wall of the rolling cylinder 17 contacts a certain position on the guiding arc surface 20. As the core column 16 rotates, the rolling cylinder 17... As the distance between the contact position of the guide arc surface 20 and the axis of the core column 16 gradually increases, the range of motion of the rolling cylinder 17 gradually decreases, thereby achieving gradual rolling and straightening of the protruding position on the steel component 30. When the rolling cylinder 17 moves relative to the axis of the core column 16, the inner wall of the rolling cylinder 17 separates from the shaping arc surface 21, and the spring piece 18 undergoes elastic deformation. When the shaping arc surface 21 is located between the core column 16 and the steel component 30, the rolling cylinder 17 returns to the state of being coaxial with the core column 16. At this time, the movement trajectory of the rolling cylinder 17 coincides with the outer wall of the steel component 30, and the rolling cylinder 17 maintains a specified pressure on the steel component 30, achieving the pressure holding effect on the steel component 30.

[0040] By utilizing the aforementioned gradual rolling straightening and pressure holding effects, the straightening amount per revolution of the pressure roller 5 can be reduced, thus lowering the difficulty of the work. It also makes it easier to maintain the straightened steel component 30 under rolling pressure for a certain period of time, thereby preventing its springback.

[0041] Furthermore, a lever 22 is provided at the end of the core post 16. The lever 22 is connected to the connecting arm 14 by a spring piece 23, and a limiting protrusion 24 is provided on the connecting arm 14 to limit the lever 22. A side plate 25 is provided on the support plate 6 or the support plate 7, and a slope 26 is provided on the side plate 25 to cooperate with the lever 22.

[0042] When the pressure roller 5 moves, it will drive the lever 22 to move synchronously. When the lever 22 moves to the position of the slope 26 on the side plate 25, the slope 26 guides the lever 22 and pushes the core column 16 to rotate through the lever 22, thereby adjusting the position of the boss 19. When the lever 22 moves to the side wall of the side plate 25 away from the support plate 6 or the support plate 7, the position of the lever 22 relative to the connecting arm 14 is fixed. At this time, the pressure roller 5 performs pressure-holding and rolling treatment on the steel component 30. When the lever 22 separates from the side plate 25, the elastic force provided by the spring plate 23 to the lever 22 will cause the lever 22 to re-fit with the limiting protrusion 24, and the lever 22 will reset.

[0043] Furthermore, rollers 27 are rotatably provided at the ends of the movable column 12 on the first support plate 6 and the ends of the movable column 12 on the second support plate 7. Guide edges 28 are provided on both the first support plate 6 and the second support plate 7. The guide edges 28 on the first support plate 6 guide the rollers 27 on the second support plate 7. The shape of the guide edges 28 on the first support plate 6 is consistent with the shape of the guide groove on the second support plate 7. The guide edges 28 on the second support plate 7 guide the rollers 27 on the first support plate 6. The shape of the guide edges 28 on the second support plate 7 is consistent with the shape of the guide groove on the first support plate 6. Two notches 29 are provided on the guide rail 28 so that the movable column 12 can pass through the notches 29 and move.

[0044] The two ends of the movable column 12 can be further supported by guide grooves, guide edges 28, and rollers 27, thereby improving the overall strength of the movable column 12 and the stability of the pressure roller 5 pressing the steel component 30. To achieve the above purpose, the shape of the guide edge 28 on the second support plate 7 needs to be consistent with the shape of the guide groove on the first support plate 6.

[0045] Since the two guide grooves are arranged opposite each other, taking the guide groove and guide edge 28 on the support plate 27 as an example, Figure 4 As shown, the area where the translation section 9 is located will intersect with the guide edge 28. That is, when the moving column 12 moves into or out of the translation section 9, the guide edge 28 will block the moving column 12, preventing the structure from moving forward. To solve this problem, two notches 29 can be set on the guide edge 28 to ensure the normal movement of the moving column 12. When the roller 27 on the guide edge 28 moves to the position of the notch 29, the guide edge 28 cannot provide support for the roller 27. Therefore, the pressure roller 5 at this position cannot effectively squeeze the steel component 30. Since the stroke at this position is short and its position is relatively off-center, it will not affect the straightening work.

[0046] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
