Description

Technical Field

[0001] This invention relates to the technical field of I-beam wheel shaping, and in particular to a straightening machine for I-beam wheel shaping. Background Technology

[0002] H-beam reels, as a common winding tool, are widely used in continuous production fields such as metal wire, cable, and steel wire rope. Their typical structure includes a central cylinder and circular side plates fixed at both ends of the cylinder. The side plates are usually made of steel plates by stamping or welding, and play a role in supporting and protecting the wire and maintaining the winding shape. In actual use, H-beam reels frequently undergo hoisting, transportation, and winding processes. The side plates are very prone to problems such as local warping and wave deformation due to mutual collisions, falling impacts, or heavy pressure. The unevenness of the side plates will not only interfere with the neat arrangement of the wire during the winding process, leading to disordered wire laying, wire jamming, or misalignment, but will also affect the stability of subsequent wire laying operations.

[0003] Currently, the correction of deformation of the side plate of the I-beam is generally carried out by manual hammering or extrusion using simple molds. Specifically, the operator uses a hammer to repeatedly hammer the protruding parts of the side plate, or places the I-beam in a simple opening and closing mold composed of upper and lower templates and uses a press to apply static pressure to achieve local shaping. However, the above methods can only clamp, position and process the I-beam one by one, and cannot form continuous or batch operations. The overall correction efficiency is low and the operation is cumbersome. Summary of the Invention

The auxiliary structures are used to drive the extrusion disks to move closer to or away from the intermediate disk when the inner ring rotates relative to the outer ring.

[0008] Furthermore, several auxiliary structures on the inner ring end face are arranged in a ring around the axis of the extrusion disk. Each auxiliary structure includes a first inclined platform and a second inclined platform that are slidably disposed relative to each other. The first inclined platform and the second inclined platform are respectively fixed to the inner ring and the extrusion disk. The projection of the sliding trajectory between the first inclined platform and the second inclined platform on the horizontal plane is an arc coaxial with the extrusion disk, and the sliding trajectory is inclined on the vertical plane.

[0009] Furthermore, the extrusion unit also includes a main sleeve and an inner shaft. The end of the main sleeve extends between the two extrusion discs. The inner ring is rotatably mounted on the main sleeve. The inner shaft is rotatably located inside the main sleeve. The main sleeve and the outer ring are connected by a connecting frame one. The inner shaft and the outer ring are connected by a connecting frame two.

[0010] Furthermore, several slide blocks are slidably disposed on both ends of the outer ring. The sliding direction of the slide blocks is along the radial direction of the outer ring.

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 9As shown, a straightening machine for shaping I-beams according to the present invention includes a rotary table 1 for conveying a plurality of I-beams 10 and an extrusion unit 2 for extruding and shaping the I-beams 10 on the rotary table 1. The rotary table 1 includes a horizontally arranged rotating ring 3 capable of rotating on its own axis, several support arms 4 arranged on the rotating ring 3, and support columns 5 arranged on each support arm 4. One end of the support column 5 is provided with a clamping structure for fixing the I-beam wheel 10, and the other end of the support column 5 is provided with a gear 6. A gear ring 7 is provided on the outer side of several gears 6, and the gears 6 and the gear ring 7 are meshed and connected. The extrusion unit 2 includes a core disk 8 and two side disks 9 located on the upper and lower sides of the core disk 8. The core disk 8 and the side disks 9 are coaxially arranged. The outer circumferential wall of the core disk 8 is used to contact the outer wall of the central cylinder of the I-beam wheel 10, and the end face of the core disk 8 cooperates with the side disks 9 to extrude and shape the side plate of the I-beam wheel 10.

[0019] In this invention, the extrusion unit 2 is located in the middle of the rotary table 1, and the extrusion unit 2 can be driven to rotate by an external motor. The rotary table 1 can transport multiple I-beams 10 around the extrusion unit 2, so that the extrusion unit 2 can continuously correct the I-beams 10 on the rotary table 1. The rotating ring 3 on the rotary table 1 can provide support for several support arms 4, several support columns 5 and several clamping structures. The clamping structures can clamp and fix the I-beams 10, and make the axis of the I-beams 10 parallel to the axis of the extrusion unit 2. The clamping structures can use multiple clamping rollers to clamp the I-beams 10 from the outside, or to support and fix the I-beams 10 from the inside of the central cylinder of the I-beams 10. As long as the I-beams 10 can be fixed on the support columns 5, it is sufficient.

[0020] The core disk 8 on the extrusion unit 2 is used in conjunction with the space between the two side plates of the I-beam wheel 10. The outer circumferential wall of the core disk 8 can contact the outer wall of the central cylinder of the I-beam wheel 10. When the core disk 8 rotates, it can drive the I-beam wheel 10 to rotate. The two side disks 9 on the core disk 8 can be located on the upper and lower sides of the I-beam wheel 10. In this way, the end faces of the side disks 9 and the core disk 8 can clamp and extrude the side plates of the I-beam wheel 10, thereby realizing the shaping work of the I-beam wheel 10.

[0021] In use, the I-beam wheel 10 is fixed to the clamping structure on the support column 5, and the two side plates of the I-beam wheel 10 extend into the two gaps between the two side discs 9 and the two end faces of the core disc 8, respectively. When the core disc 8 rotates, the friction between the outer circumference of the core disc 8 and the outer wall of the central cylinder of the I-beam wheel 10 drives the I-beam wheel 10 to rotate. This causes different positions on the side plates of the I-beam wheel 10 to slide into the gaps between the end faces of the side discs 9 and the core disc 8 in sequence. These gaps can be used to compress and shape the side plates, gradually restoring the deformed side plates to a flat shape. At the same time, as the I-beam wheel 10 rotates... The rotation of the gap allows for comprehensive shaping of the side plates, thus enabling the shaping of both side plates using two gaps. When the I-beam 10 rotates, it drives the support column 5 and gear 6 to move synchronously. Since gear 6 meshes with the gear ring 7, gear 6 rolls on the gear ring 7, thereby driving the rotating ring 3 to rotate. When the next support column 5 moves to the loading / unloading position, it can fix the next I-beam 10 on the clamping structure on the support column 5. Thus, with the rotation of the rotating ring 3, continuous shaping and correction of several I-beams 10 can be achieved.

[0022] It should be noted that the rotational power of the rotating ring 3 is mainly provided by the core disk 8, and when the gear 6 on a support arm 4 rolls, it can drive other gears 6 to move synchronously through the rotating ring 3, thereby causing several I-beam wheels 10 to rotate synchronously. Since the core disk 8 and the I-beam wheels 10 rotate synchronously relative to each other, any position on the side plates on both sides of the I-beam wheels 10 can enter the gap between the end face of the core disk 8 and the side disk 9 multiple times, thereby realizing repeated correction processing of the side plates on the I-beam wheels 10.

[0023] By rotating and conveying several I-beams 10 around the extrusion unit 2, the extrusion unit 2 can perform synchronous and continuous straightening processing on several I-beams 10, which facilitates the rapid processing of a large number of I-beams 10 and effectively improves work efficiency. At the same time, by using the core disk 8 and side disk 9 on the extrusion unit 2 to rotate and extrude the side plates of the I-beams 10, the I-beams 10 can achieve a comprehensive and automatic straightening function of the side plates during rotation, which effectively simplifies the operation. The rotational motion power and circumferential conveying motion power of the I-beams 10 can be directly provided by the core disk 8, which effectively simplifies the structure and reduces equipment costs.

[0024] Furthermore, the rotary table 1 also includes a fixed disk 11, on which an annular groove is formed. The annular groove is composed of an arc groove 12 and an arc groove 13. The arc groove 12 is coaxially arranged with the rotating ring 3, and the arc groove 13 is offset from the axis of the rotating ring 3. Several sliding columns 14 are slidably arranged in the annular groove, and the sliding columns 14 are connected to the gear 6. The rotating ring 3 is rotatably mounted on the fixed disk 11, the support arm 4 is slidably mounted along the radial direction of the rotating ring 3, and the shape of the toothed ring 7 is consistent with the shape of the ring groove.

[0025] The fixed plate 11 can be directly fixed to the external base. The fixed plate 11 provides support for the rotating ring 3. When the support column 5 moves, it will drive the sliding column 14 to slide in the ring groove through the gear 6. When the sliding column 14 moves in the arc groove 12, the I-beam wheel 10 is in the correction position. At this time, the extrusion unit 2 corrects the I-beam wheel 10. When the sliding column 14 moves in the arc groove 23, the sliding column 14 moves away from the axis of the core plate 8. At this time, the support column 5 and the I-beam wheel 10 on it also move away from the extrusion unit 2. Thus, the support column 5 is moved to the loading and unloading position, which makes it easy to remove the I-beam wheel 10 on the support column 5 and replace the next I-beam wheel 10. Since the support column 5 is deviated from the axis of the core plate 8 at this time, the support arm 4 will slide on the rotating ring 3, and the gear 6 remains engaged with the gear ring 7.

[0026] Furthermore, the core disk 8 consists of two extrusion disks 15 arranged opposite to each other and a number of side posts 16 located between the two extrusion disks 15. The two extrusion disks 15 are respectively arranged corresponding to the two side disks 9. The number of side posts 16 are distributed in a ring around the axis of the extrusion disks 15. The adjacent side posts 16 are slidably connected to each other, and the adjacent side posts 16 are respectively fixed on the two extrusion disks 15. The distance between the two extrusion disks 15 can be adjusted by the number of side posts 16.

[0027] Since the adjacent two side columns 16 are slidably connected to each other, the distance between the two extrusion discs 15 is adjustable, and the thickness of the core disc 8 along the axial direction is adjustable. This facilitates the correction of I-beam wheels 10 of different specifications. At the same time, when the two extrusion discs 15 approach each other, the distance between the extrusion disc 15 and the side disc 9 will increase. This makes it easier for a part of the side plate of the I-beam wheel 10 to be smoothly inserted into the gap between the extrusion disc 15 and the side disc 9. When the two extrusion discs 15 move away from each other and reset, the extrusion disc 15 and the side disc 9 cooperate to extrude and correct the part of the side plate between them. This makes it easier for the extrusion unit 2 and the I-beam wheel 10 to complete the initial assembly.

[0028] Furthermore, the extrusion unit 2 also includes an intermediate disk 17 located between the two extrusion disks 15. The intermediate disk 17 is composed of an inner ring 19 located on the inner side and an outer ring 18 located on the outer side. The inner ring 19 can rotate on the outer ring 18. The side column 16 is slidably connected to the outer ring 18. Several auxiliary structures are respectively provided on the two end faces of the inner ring 19. The auxiliary structures are used to drive the extrusion disks 15 to move closer to or away from the intermediate disk 17 when the inner ring 19 rotates relative to the outer ring 18.

[0029] The outer ring 18 can support the extrusion plate 15 through the side column 16, and the inner ring 19 can provide support for the two extrusion plates 15 through the auxiliary structure. That is, when the inner ring 19 is relatively stationary with respect to the outer ring 18, the two extrusion plates 15 are relatively stationary. At this time, the two extrusion plates 15 cooperate with the two side plates 9 to correct the two side plates on the H-beam wheel 10. When the inner ring 19 rotates relative to the outer ring 18, the inner ring 19 will drive the two extrusion plates 15 to move closer or further away from each other through the auxiliary structure, thereby adjusting the distance between the two extrusion plates 15.

[0030] Furthermore, several auxiliary structures on the end face of the inner ring 19 are arranged in a ring around the axis of the extrusion plate 15. The auxiliary structures include a first inclined platform 20 and a second inclined platform 21 that are slidably arranged relative to each other. The first inclined platform 20 and the second inclined platform 21 are respectively fixed on the inner ring 19 and the extrusion plate 15. The projection of the sliding trajectory between the first inclined platform 20 and the second inclined platform 21 on the horizontal plane is an arc coaxial with the extrusion plate 15, and the sliding trajectory is inclined on the vertical plane.

[0031] like Figure 7 As shown, the relative motion trajectory between inclined platform 1 20 and inclined platform 21 is an inclined arc. When the inner ring 19 rotates relative to the outer ring 18, the outer ring 18 restricts the extrusion plate 15 through the side column 16, preventing the extrusion plate 15 from rotating relative to the outer ring 18. Therefore, inclined platform 1 20 on the inner ring 19 will slide relative to inclined platform 21 on the extrusion plate 15. The sliding trajectory is an inclined arc. At this time, the extrusion plate 15 will move closer to or away from the inner ring 19, thereby adjusting the position between the two extrusion plates 15.

[0032] It should be noted that the intermediate plate 17 can locate the center point between the two extrusion plates 15. The two extrusion plates 15 will move synchronously relative to each other. By utilizing the special motion trajectory between the inclined platform 1 20 and the inclined platform 21, the rotation of the inner ring 19 can be converted into the vertical movement of the extrusion plate 15.

[0033] Furthermore, the extrusion unit 2 also includes a main sleeve 22 and an inner shaft 23. The end of the main sleeve 22 extends between the two extrusion discs 15. The inner ring 19 is rotatably mounted on the main sleeve 22. The inner shaft 23 is rotatably located inside the main sleeve 22. The main sleeve 22 is connected to the outer ring 18 by a connecting bracket 1 24. The inner shaft 23 is connected to the outer ring 18 by a connecting bracket 25.

[0034] The main sleeve 22 provides support for the intermediate disc 17. The outer ring 18 is located outside the inner ring 19, the inner ring 19 is located outside the main sleeve 22, and the main sleeve 22 is located outside the inner shaft 23. Therefore, the outer ring 18 and the main sleeve 22 are separated by the inner ring 19, and the inner ring 19 and the inner shaft 23 are separated by the main sleeve 22. To achieve the connection between the outer ring 18 and the main sleeve 22, and the connection between the inner ring 19 and the inner shaft 23, the following can be used: Figure 7The connecting frame 1 24 and connecting frame 25 shown are as follows: Connecting frame 1 24 consists of a central ring and several extension arms 1 located on the outer side of the ring. The ring is connected to the main sleeve 22, and the extension arms 1 are connected to the outer ring 18. Connecting frame 25 consists of a central disk and several extension arms 2 located on the disk. The disk is connected to the top of the inner shaft 23, and the extension arms 2 are connected to the inner ring 19. The extension arms 1 and extension arms 2 are staggered, thereby realizing the connection between the outer ring 18 and the main sleeve 22, and the connection between the inner ring 19 and the inner shaft 23. When the inner shaft 23 rotates at a certain angle, the inner shaft 23 can drive the inner ring 19 to rotate through connecting frame 2 25, thereby controlling the two extrusion discs 15 to move closer or further apart. The main sleeve 22 can provide support to the outer ring 18 through connecting frame 1 24, which facilitates operation.

[0035] It should be noted that the external motor can directly drive the main sleeve 22 to rotate, thereby causing the extrusion unit 2 to rotate.

[0036] Furthermore, several slide blocks 26 are slidably arranged on both ends of the outer ring 18. The sliding direction of the slide blocks 26 is along the radial direction of the outer ring 18. A drive arm 1 27 and a drive arm 28 are rotatably arranged on the slide blocks 26. The drive arm 1 27 and the drive arm 28 are inclined relative to each other. The drive arm 1 27 is rotatably connected to the extrusion plate 15. A drive arm 3 29 is rotatably arranged on the drive arm 28. The drive arm 3 29 slides vertically through the extrusion plate 15 and is connected to the corresponding side plate 9.

[0037] When the extrusion plate 15 moves toward the middle plate 17, the extrusion plate 15 will push the slide 26 to move through the drive arm 1 27. At this time, the slide 26 can push the drive arm 3 29 away from the middle plate 17 through the drive arm 2 28. The drive arm 3 29 then pushes the side plate 9 away from the middle plate 17, thereby making the side plate 9 and the extrusion plate 15 move away from each other synchronously, increasing the gap between the side plate 9 and the extrusion plate 15. This makes it easier for the side plate on the H-beam wheel 10 to be inserted between the side plate 9 and the extrusion plate 15. This avoids the situation where, when only the extrusion plate 15 moves, there is a deformed position on the side plate toward the side plate 9, the side plate cannot be smoothly inserted between the extrusion plate 15 and the side plate 9.

[0038] Several slide blocks 26 on the end face of the outer ring 18 are arranged in a ring. When the extrusion plate 15 moves, the slide blocks 26 will drive the side plate 9 to move synchronously, thereby improving the stability and structural strength of the movement of the side plate 9 and the extrusion plate 15.

[0039] Furthermore, the bottom of the inner shaft 23 extends beyond the main sleeve 22, a spiral groove 30 is provided on the outer wall of the inner shaft 23, a drive ring 31 is slidably sleeved on the inner shaft 23, a protrusion is provided on the inner wall of the drive ring 31 to cooperate with the spiral groove 30, a movable ring 32 is provided on the outer wall of the main sleeve 22 to slide along the axis of the main sleeve 22, and the movable ring 32 and the drive ring 31 are connected by a connecting rod 33. The drive ring 31 is connected to the main sleeve 22 by a spring 34. A fixed cylinder 35 is sleeved on the outside of the movable ring 32. The fixed cylinder 35 is fixedly set relative to the fixed disk 11. Several bosses 36 are provided at the end of the fixed cylinder 35 around the axis of the extrusion disk 15. A sliding column 37 that cooperates with the bosses 36 is provided on the movable ring 32.

[0040] When the main sleeve 22 rotates, it drives the inner shaft 23, drive ring 31, movable ring 32, connecting rod 33, spring 34, and slide column 37 to move synchronously. When slide column 37 moves between two adjacent bosses 36 on the fixed cylinder 35, the extrusion disc 15 and the side disc 9 separate. When slide column 37 moves onto the boss 36, it drives the movable ring 32 to slide on the main sleeve 22. The movable ring 32 pushes the drive ring 31 to move synchronously through the connecting rod 33, and the spring 34 is compressed. Since the drive ring 31 and the inner shaft 23 are engaged by the spiral groove 30 and the protrusion, the movement of the drive ring 31 drives the inner shaft 23 to rotate, thereby bringing the extrusion disc 15 and the side disc 9 closer together, that is, the slide column 37 moves on the boss 36. During the process, the extrusion plate 15 and the side plate 9 approach each other and maintain the working state of correcting the upper side plate of the I-beam 10. When the second slide column 37 moves again between the two adjacent bosses 36, the spring 34 extends and provides a reset force to the drive ring 31. The extrusion plate 15 and the side plate 9 separate from each other again. At this time, a part of the upper side plate of the next I-beam 10 can be smoothly inserted between the extrusion plate 15 and the side plate 9, realizing the smooth assembly and combination of the next I-beam 10 and the extrusion unit 2. As the second slide column 37 moves continuously on several bosses 36, the extrusion plate 15 and the side plate 9 can be separated from each other after maintaining the extrusion state for a specified time, and then maintain the extrusion state again, thereby realizing the repeated extrusion operation on the upper side plate of the I-beam 10.

[0041] 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.
