Description

Technical Field

[0001] This invention belongs to the field of parts straightening technology, specifically referring to an automatic straightening device for forging shaping. Background Technology

[0002] After heat treatment, shaft parts may naturally bend slightly due to stress release and their own weight during the resting stage. Before use, these parts need to be straightened. This process is usually accomplished using multiple sets of rollers arranged in an array. As the diameter of the rollers gradually increases, the constraint gap of the workpiece also gradually decreases, thereby achieving a gradual straightening effect. Currently, the workpiece is usually straightened by two symmetrically arranged rollers, which is inefficient, has a single pressure direction, and there is room for improvement in the effect. Summary of the Invention

[0003] In response to the above situation, in order to improve the efficiency of rolling and the uniformity of the pressure direction, this solution proposes a rolling method with multiple sets of annularly arranged rolling components. Compared with the prior art, increasing the number of straightening rolling shafts can not only increase the number of straightening rolling rollers and rolling efficiency, but also increase the density of the pressure direction and improve the uniformity of rolling straightening. To achieve synchronous movement of the uniformly distributed straightening and rolling shafts in annular arrangement, the simplest and most reliable drive solution is to use an external gear ring meshing with annular planetary gears. However, adjusting the position of the straightening and rolling shafts to accommodate workpieces of different diameters is a problem that must be solved.

[0004] To solve this problem, this invention creatively proposes a hemispherical external gear and a hemispherical internal gear. Since the upper and lower circumferences of the hemispherical external gear are different but the number of teeth remains the same, the module of the teeth on the hemispherical external gear gradually increases from top to bottom. The same applies to the teeth on the hemispherical internal gear. As the meshing position moves, the modules of the hemispherical external gear and the hemispherical internal gear at the meshing point can remain equal, thereby ensuring that the power transmission of the arc-shaped transmission component can still be maintained during the position adjustment of the straightening rolling shaft.

[0005] The technical solution adopted by this invention is as follows: This invention proposes an automatic straightening device for forging forming, including an arc-shaped transmission assembly, an annular rolling assembly, an axial guide assembly, an axial adjustment assembly, a straightening drive assembly, a spacing synchronization locking assembly, and a traction assembly. The arc-shaped transmission assembly is disposed on the annular rolling assembly and the axial guide assembly. Several groups of annular rolling assemblies are evenly distributed in a ring. The two ends of the annular rolling assembly are slidably disposed on the spacing synchronization locking assembly. The axial guide assembly is disposed between the spacing synchronization locking assemblies. The axial adjustment assembly is disposed on the axial guide assembly. The straightening drive assembly is disposed on the spacing synchronization locking assembly. The straightening drive assembly is located outside the axial guide assembly. The traction assembly is located at the center of the annular rolling assembly.

[0006] During the slow rotation of the circumferential rolling assembly, the workpiece is slowly pulled through the center gap of the circumferential rolling assembly by the traction assembly. The workpiece with a small degree of bending can be squeezed and straightened by the straightening rolling roller, so that the bending amplitude is reduced and the axial deviation is reduced to the target range.

[0007] Furthermore, the arc-shaped transmission assembly includes a hemispherical external gear and a hemispherical internal gear, which mesh and transmit power. When the hemispherical internal gear slides axially, the hemispherical external gear slides radially under the push of the hemispherical internal gear.

[0008] Both the external and internal hemispherical gears have variable module teeth at their meshing points, which allows the number of teeth to remain constant even when the diameter changes. Furthermore, due to the change in meshing position, when the internal hemispherical gear slides axially, the external hemispherical gear will slide radially under the push of the internal hemispherical gear.

[0009] Furthermore, the circumferential rolling assembly includes a straightening rolling shaft and straightening rolling rollers. The two ends of the straightening rolling shaft are slidably mounted on the spacing synchronization locking assembly. The straightening rolling rollers are fixedly connected to the straightening rolling shaft. The straightening rolling rollers are not overlapped in the axial distribution. From one end to the other, the diameter of the straightening rolling rollers gradually increases.

[0010] The straightening rollers are staggered in the axial direction to avoid interference between them. The diameter of the straightening rollers changes sequentially, which allows the diameter of the middle area of ​​the straightening rollers to gradually decrease. Thus, through multiple small-amplitude straightening operations, the workpiece is gradually shaped.

[0011] Furthermore, the axial guide assembly includes a central guide rod, a sliding sleeve rod, and a rotating base plate. The two ends of the central guide rod are fixed to the spacing synchronization locking assembly. The sliding sleeve rod is engaged and slidably disposed on the central guide rod. The rotating base plate is disposed at both ends of the sliding sleeve rod. The hemispherical internal gear is rotatably disposed on the rotating base plate.

[0012] Furthermore, the axial adjustment assembly includes a connecting ring, a push rod seat, and an axial push rod. The connecting ring is fixed to the sliding sleeve rod, and the connecting ring is symmetrically provided with ears. The push rod seat is fixed to the spacing synchronization locking assembly, and the axial push rod is fixed to the push rod seat. The telescopic rod of the axial push rod is provided on the ears.

[0013] The extension and retraction of the axial push rod can push the connecting circlip and the axial guide assembly to slide axially, thereby changing the axial position of the hemispherical internal gear, and thus realizing the radial position adjustment of the hemispherical external gear, so that the center clearance of the ring rolling assembly can match workpieces of different diameters.

[0014] Furthermore, the correction drive assembly includes a drive shaft and a drive spur gear. The drive shaft is rotatably disposed in the spacing synchronization locking assembly. The drive spur gear is fixedly connected to the drive shaft. The hemispherical internal gear is provided with an external spur tooth portion. The drive spur gear and the external spur tooth portion mesh and transmit power. One end of the drive shaft is provided with a drive part connected to an external drive source.

[0015] The width of the driving spur gear is smaller than the width of the external spur gear, so the driving spur gear and the external spur gear can still maintain meshing when the hemispherical internal gear is axially displaced.

[0016] Furthermore, the spacing synchronization locking assembly includes an end plate and a synchronization disk. The synchronization disk is rotatably mounted on the end plate, and the end plate is provided with a straight slide groove. The straightening rolling shaft is slidably mounted in the straight slide groove. The synchronization disk is provided with an oblique slide groove, and the straightening rolling shaft is slidably mounted in the oblique slide groove.

[0017] The synchronous disc can limit the synchronous sliding of each group of annular rolling components, and the position of the straightening rolling shaft can also be locked by locking the synchronous disc.

[0018] Preferably, the two ends of the central guide rod are fixed to the end plate, the push rod seat is fixed to the end plate, and the end plate has a central hole at its center.

[0019] Furthermore, the traction assembly includes a workpiece, a connector, and a traction rope. The connector is located at both ends of the workpiece, and the traction rope is connected to an external traction mechanism.

[0020] The beneficial effects achieved by the present invention using the above structure are as follows: (1) During the slow rotation of the circumferential rolling assembly, the workpiece is slowly pulled through the center gap of the circumferential rolling assembly by the traction assembly. The workpiece with a small bending can be squeezed and straightened by the straightening rolling wheel, so that the bending amplitude is reduced and the axial deviation is reduced to the target range.

[0021] (2) Both the external hemispherical gear and the internal hemispherical gear have variable module teeth at the meshing point, so that the number of teeth can remain unchanged when the diameter changes. Also, due to the change in meshing position, when the internal hemispherical gear slides axially, the external hemispherical gear will slide radially under the push of the internal hemispherical gear.

[0022] (3) The straightening rollers are staggered in the axial direction to avoid mutual interference between the straightening rollers. The diameter of the straightening rollers changes in sequence, which can make the diameter of the middle area of ​​the straightening rollers gradually shrink. Thus, the workpiece is gradually shaped through multiple small-amplitude straightening.

[0023] (4) The extension and retraction of the axial push rod can push the connecting ring and the axial guide assembly to slide axially, thereby changing the axial position of the hemispherical internal gear, and thus realizing the radial position adjustment of the hemispherical external gear, so that the center gap of the ring rolling assembly can match the workpieces of different diameter specifications.

[0024] (5) The width of the driving spur gear is smaller than the width of the outer spur tooth. Therefore, when the hemispherical internal gear is axially displaced, the driving spur gear and the outer spur tooth can still maintain meshing.

[0025] (6) The synchronous sliding of each group of ring rolling components can be restricted by the synchronous disc, and the position of the straightening rolling shaft can be locked at the same time by locking the synchronous disc. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. 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 limitations on this invention.

[0031] like Figures 1-9 As shown, this invention proposes an automatic straightening device for forging forming, including an arc-shaped transmission assembly 1, an annular rolling assembly 2, an axial guide assembly 3, an axial adjustment assembly 4, a straightening drive assembly 5, a spacing synchronization locking assembly 6, and a traction assembly 7. The arc-shaped transmission assembly 1 is disposed on the annular rolling assembly 2 and the axial guide assembly 3. The annular rolling assembly 2 is evenly distributed in several groups in a ring. The two ends of the annular rolling assembly 2 are slidably disposed on the spacing synchronization locking assembly 6. The axial guide assembly 3 is disposed between the spacing synchronization locking assemblies 6. The axial adjustment assembly 4 is disposed on the axial guide assembly 3. The straightening drive assembly 5 is disposed on the spacing synchronization locking assembly 6 and is located outside the axial guide assembly 3. The traction assembly 7 is located at the center of the annular rolling assembly 2.

[0032] During the slow rotation of the circumferential rolling assembly 2, the workpiece 71 is slowly pulled through the center gap of the circumferential rolling assembly 2 by the traction assembly 7. The workpiece 71 with a small degree of bending can be squeezed and straightened by the straightening rolling roller 22, so that the bending amplitude is reduced and the axial deviation is reduced to the target range.

[0033] The arc-shaped transmission assembly 1 includes a hemispherical external gear 11 and a hemispherical internal gear 12. The hemispherical external gear 11 and the hemispherical internal gear 12 mesh and transmit power. When the hemispherical internal gear 12 slides axially, the hemispherical external gear 11 will slide radially under the push of the hemispherical internal gear 12.

[0034] The hemispherical external gear 11 and hemispherical internal gear 12 are both variable-module teeth at their meshing points, so that the number of teeth can remain constant when the diameter changes. Furthermore, due to the change in meshing position, when the hemispherical internal gear 12 slides axially, the hemispherical external gear 11 will slide radially under the push of the hemispherical internal gear 12.

[0035] The circumferential rolling assembly 2 includes a straightening rolling shaft 21 and straightening rolling rollers 22. The two ends of the straightening rolling shaft 21 are slidably mounted on the spacing synchronization locking assembly 6. The straightening rolling rollers 22 are fixedly connected to the straightening rolling shaft 21. The straightening rolling rollers 22 are not overlapping in the axial distribution. From one end to the other end, the diameter of the straightening rolling rollers 22 gradually increases.

[0036] The straightening rollers 22 are staggered in the axial direction to avoid mutual interference between them. The diameter of the straightening rollers 22 changes sequentially, which makes the diameter of the middle area of ​​the straightening rollers 22 gradually decrease. Thus, through multiple small-amplitude straightening, the workpiece 71 is gradually shaped.

[0037] The axial guide assembly 3 includes a central guide rod 31, a sliding sleeve rod 32, and a rotating base plate 33. The two ends of the central guide rod 31 are fixed to the spacing synchronization locking assembly 6. The sliding sleeve rod 32 is engaged and slidably disposed on the central guide rod 31. The rotating base plate 33 is disposed at both ends of the sliding sleeve rod 32. The hemispherical internal gear 12 is rotatably disposed on the rotating base plate 33.

[0038] The axial adjustment assembly 4 includes a connecting ring 41, a push rod seat 42, and an axial push rod 43. The connecting ring 41 is fixed to the sliding sleeve 32, and the connecting ring 41 is symmetrically provided with ears 411. The push rod seat 42 is fixed to the spacing synchronization locking assembly 6, and the axial push rod 43 is fixed to the push rod seat 42. The telescopic rod of the axial push rod 43 is provided on the ears 411.

[0039] The extension and retraction of the axial push rod 43 can push the connecting ring 41 and the axial guide assembly 3 to slide axially, thereby changing the axial position of the hemispherical internal gear 12, and thus realizing the radial position adjustment of the hemispherical external gear 11, so that the center gap of the ring rolling assembly 2 can match the workpiece 71 with different diameter specifications.

[0040] The correction drive assembly 5 includes a drive shaft 51 and a drive spur gear 52. The drive shaft 51 is rotatably mounted in the pitch synchronization locking assembly 6. The drive spur gear 52 is fixedly connected to the drive shaft 51. The hemispherical internal gear 12 is provided with an external spur tooth 121. The drive spur gear 52 and the external spur tooth 121 mesh and transmit power. One end of the drive shaft 51 is provided with a drive part 511 connected to an external drive source.

[0041] The width of the drive spur gear 52 is smaller than the width of the outer spur tooth portion 121, so the drive spur gear 52 and the outer spur tooth portion 121 can still maintain meshing when the hemispherical internal gear 12 is axially displaced.

[0042] The spacing synchronization locking assembly 6 includes an end plate 61 and a synchronization disk 62. The synchronization disk 62 is rotatably mounted on the end plate 61. The end plate 61 is provided with a straight slide groove 612, and the straightening rolling shaft 21 is slidably mounted in the straight slide groove 612. The synchronization disk 62 is provided with an oblique slide groove 621, and the straightening rolling shaft 21 is slidably mounted in the oblique slide groove 621.

[0043] The synchronous sliding of each group of annular rolling components 2 can be restricted by the synchronous disc 62, and the position of the straightening rolling shaft 21 can also be locked by locking the synchronous disc 62.

[0044] The two ends of the central guide rod 31 are fixed to the end plate 61, the push rod seat 42 is fixed to the end plate 61, and the end plate 61 has a central hole 611 at the center.

[0045] The traction assembly 7 includes a workpiece 71, a connector 72, and a traction rope 73. The connector 72 is located at both ends of the workpiece 71, and the traction rope 73 is connected to an external traction mechanism.

[0046] like Figure 10 As shown, the section line area represents the cross-section of the hemispherical internal gear 12, the intersection of the sector area and the dotted line represents the meshing position of the hemispherical external gear 11 and the hemispherical internal gear 12, and the two sector areas with solid and dashed lines represent the positions of the hemispherical external gear 11 at different meshing points. When the axial position (longitudinal direction in the figure) of the hemispherical internal gear 12 relative to the hemispherical external gear 11 changes, it will push the hemispherical external gear 11 to move radially (transverse direction in the figure) with an amplitude of d. Teeth are provided on the outer side of the hemispherical external gear 11 and the inner side of the hemispherical internal gear 12. Since the upper and lower circumferences of the hemispherical external gear 11 are different but the number of teeth remains the same, the module of the teeth on the hemispherical external gear 11 gradually increases from top to bottom. The same applies to the teeth on the hemispherical internal gear 12. As the meshing position moves, the module of the hemispherical external gear 11 and the hemispherical internal gear 12 at the meshing point remains equal.

[0047] In practical use, the user first needs to drive the drive shaft 51 to rotate through an external drive device, and at the same time drive the internal hemispherical gear 12 to rotate through the drive spur gear 52. When the internal hemispherical gear 12 rotates, it drives the straightening rolling shaft 21 and the straightening rolling wheel 22 to rotate through meshing with the external hemispherical gear 11. The straightening rolling wheels 22 do not overlap in the axial direction and rotate in the same direction.

[0048] Then, by means of external mechanism or manual pulling, the workpiece 71 is pulled through the center gap of the straightening roller 22. As the diameter of the straightening roller 22 gradually increases, the center gap of the straightening roller 22 gradually decreases. Therefore, during the axial displacement of the workpiece 71, the circumferential rolling assembly 2 can gradually straighten the workpiece 71 in a small amount.

[0049] When workpiece 71 extends from the other end, it has completed its own straightening.

[0050] When the diameter of the workpiece 71 changes, the spacing of the circumferential rolling assembly 2 needs to be adjusted accordingly to change the size of the center gap of the straightening rolling roller 22.

[0051] At this time, the synchronization disk 62 is first unlocked, and then the extension and retraction of the axial push rod 43 can push the connecting ring 41 and the axial guide assembly 3 to slide axially, while the hemispherical internal gears 12 at both ends slide axially synchronously. When the hemispherical internal gears 12 move axially, they will push the hemispherical external gears 11 to move radially, thereby pushing the straightening rolling shaft 21 to slide along the straight slide groove 612. Teeth are provided on the outer side of the hemispherical external gear 11 and the inner side of the hemispherical internal gear 12. Since the upper and lower circumferences of the hemispherical external gear 11 are different but the number of teeth remains the same, the module of the teeth on the hemispherical external gear 11 gradually increases from top to bottom. The same applies to the teeth on the hemispherical internal gear 12. As the meshing position moves, the module of the hemispherical external gear 11 and the hemispherical internal gear 12 at the meshing point remains equal.

[0052] Since the straightening rolling shafts 21 are also located in the inclined slide grooves 621, under the action of the synchronizing disc 62, each straightening rolling shaft 21 can move closer or further away synchronously; after the adjustment is completed, the synchronizing disc 62 can be locked again.

[0053] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0054] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
