In the description of the present invention, "multiple" and "several" mean two or more, unless otherwise clearly and specifically defined.

[0028] Please also refer to Figures 1 to 8The present invention now provides a guide device for a high-speed wire rod rolling mill. The guide device comprises a guide body 1, an adjustment seat 2, and a mounting seat 3. The guide body 1 is slidably connected to the adjustment seat 2 via a first adjustment assembly 4. The guide body 1 slides perpendicularly to the direction of travel of the workpiece 10. The adjustment seat 2 is provided with a first locking assembly 6 for locking the first adjustment assembly 4. The adjustment seat 2 is slidably connected to the mounting seat 3 along the direction of travel of the workpiece 10 via a second adjustment assembly 5. The mounting seat 3 is provided with a second locking assembly 7 for locking the second adjustment assembly 5.

[0029] The present embodiment provides a guide device for a high-speed wire rolling mill. Compared with the prior art, the guide body 1 is connected to the adjustment seat 2, and the first adjustment component 4 drives the guide body 1 to move laterally perpendicular to the running direction of the rolled piece 10, and the second adjustment component 5 drives the adjustment seat 2 and the guide body 1 to move longitudinally along the running direction of the rolled piece 10, thereby realizing all-round adjustment of the centering position of the guide body 1. On this basis, the first locking component 6 and the second locking component 7 are respectively braked by the first adjusting component 4 and the second adjusting component 5, thereby locking the centering position of the adjustment seat 2 and the guide body 1. When the guide body 1 is disassembled and replaced, it is only necessary to connect the calibrated guide body 1 to the adjustment seat 2, and there is no need to readjust the online position of the guide body 1, which reduces the alignment time of the guide body 1, effectively improves the installation efficiency of the guide body 1, helps to ensure product quality, and improves production efficiency and economic benefits.

[0030] It should be noted that the guide body 1 primarily comprises a guide housing, a guide wheel arm, a guide wheel 13, and a nose cone 14. The wire rod 10 passes through the gap between the two guide wheels 13 and, after being guided by the nose cone 14, enters the rolling mill between the rollers for rolling. Adjustment of the gap between the two guide wheels 13 of the guide body 1 and alignment of the gap between the guide wheels 13 and the nose cone 14 are performed offline using an alignment instrument. In this embodiment, the calibrated guide body 1 is mounted on the adjustment base 2. The first adjustment assembly 4 and the second adjustment assembly 5 respectively adjust the lateral and longitudinal positions of the guide body 1 online to adjust the offset distance between the nose cone 14 of the guide body 1 and the rolling mill rollers. After the position is adjusted, the first locking assembly 6 and the second locking assembly 7 lock the alignment position. The next time the guide body 1 is replaced, only the calibrated guide body 1 needs to be connected to the adjustment base 2, eliminating the need for online adjustment of the guide body 1. This significantly shortens the installation time of the guide device and improves installation efficiency. During actual use, the positions of the adjustment seat 2 and the guide body 1 can be regularly fine-tuned by the first adjustment component 4 and the second adjustment component 5 to ensure the installation accuracy of the guide device and the product quality.

[0031] As a specific embodiment of the guide device for high-speed wire rolling mill provided by the utility model, see Figures 1 to 7 The first adjusting component 4 includes an adjusting plate 41 connected to the bottom of the guide body 1 and an adjusting bolt 42 rotatably connected to the adjusting seat 2. The top surface of the adjusting seat 2 is provided with a slide groove 21 perpendicular to the running direction of the rolled piece 10. The adjusting plate 41 slides with the slide groove 21. The adjusting bolt 42 passes through the adjusting plate 41 and is threadedly connected to the adjusting plate 41 to drive the adjusting plate 41 to move. The bottom of the guide body 1 is provided with a positioning groove 11 extending through the running direction of the rolled piece 10, and the top wall of the adjusting plate 41 is provided with an upper positioning boss 411 that is plugged into the positioning groove 11.

[0032] In this embodiment, the positioning connection between the guide body 1 and the adjustment plate 41 is achieved by plugging and fitting the positioning groove 11 at the bottom of the guide body 1 with the upper positioning boss 411 on the top wall of the adjustment plate 41. At the same time, the sliding fit between the adjustment plate 41 and the slide groove 21 enables the guide body 1 to move laterally along the running direction perpendicular to the rolled piece 10.

[0033] Specifically, a threaded hole is provided on the adjustment plate 41, and the adjusting bolt 42 is threadedly connected to the threaded hole of the adjustment plate 41. At the same time, the adjustment plate 41 is constrained by the slide groove 21. When the adjusting bolt 42 is rotated, the adjustment plate 41 can make a translational motion along the slide groove 21, thereby driving the upper guide body 1 to move, thereby realizing the adjustment of the lateral position of the guide body 1.

[0034] As a specific embodiment of the guide device for high-speed wire rolling mill provided by the utility model, see Figure 3 and Figure 5 A fixing plate 23 is connected to the outer wall of the adjustment seat 2, and the adjusting bolt 42 is set through the fixing plate 23 and rotates with the fixing plate 23. The outer periphery of the adjusting bolt 42 is provided with a concave limiting ring 421, which is engaged with the fixing plate 23 to limit the axial movement of the adjusting bolt 42.

[0035] In this embodiment, a through hole is provided on the fixing plate 23, and the width of the limiting concave ring 421 is consistent with the length of the through hole. The ring bottom of the limiting concave ring 421 is rotatably engaged with the through hole, and the two side bosses of the limiting concave ring 421 are snap-fitted with the two side walls of the fixing plate 23 to limit the axial movement of the adjusting bolt 42, so that the adjusting bolt 42 can only rotate in the through hole of the fixing plate 23, and then the adjusting plate 41 is driven to move laterally through the threaded engagement of the adjusting bolt 42 and the adjusting plate 41.

[0036] As a specific embodiment of the guide device for high-speed wire rolling mill provided by the utility model, see Figures 3 to 7The bottom wall of the slide 21 is provided with a receiving groove 211 extending along the direction of the slide 21, and the bottom wall of the adjustment plate 41 is provided with a lower positioning boss 412 slidingly matched with the receiving groove 211. The adjusting bolt 42 is threadedly connected to the lower positioning boss 412, and the end wall of the adjustment seat 2 is threadedly connected with a locking bolt 24. The extending end of the locking bolt 24 extends into the receiving groove 211 to abut against the side wall of the lower positioning boss 412.

[0037] In this embodiment, the combination of the receiving groove 211 and the slide groove 21 allows for more precise positioning of the adjustment plate 41 and a smoother sliding process. Furthermore, the provision of the lower positioning boss 412 facilitates the threaded connection between the adjustment plate 41 and the adjustment bolt 42, thereby helping to reduce the thickness of the adjustment plate 41. Furthermore, when the adjustment plate 41 is moved to the desired centered position by rotating the adjustment bolt 42, the locking bolt 24 can be tightened so that the extended end of the locking bolt 24 passes through the wall of the receiving groove 211 and abuts against the side wall of the lower positioning boss 412, thereby locking the adjustment plate 41 within the slide groove 21.

[0038] Specifically, the locking bolt 24 extends along the running direction of the rolled product 10 and is disposed perpendicular to the central axis of the adjusting bolt 42. The end surface of the extended end of the locking bolt 24 can press against the side wall of the lower positioning boss 412, thereby pressing the lower positioning boss 412 into the receiving groove 211, thereby fixing the position of the adjustment plate 41. The locking bolt 24 cooperates with the first locking assembly 6 and is used to lock the locking bolt 24, ensuring the position of the adjustment plate 41 and, in turn, the centering position of the guide body 1.

[0039] As a specific embodiment of the guide device for high-speed wire rolling mill provided by the utility model, see Figures 1 to 3 The bottom of the guide body 1 is provided with a first dovetail platform 12 extending perpendicular to the running direction of the rolled piece 10, and the end of the adjustment seat 2 is provided with a dovetail half groove 25 that slides with one side of the first dovetail platform 12, and the other end of the adjustment seat 2 is connected to a clamping plate 8 that abuts against the other side of the first dovetail platform 12.

[0040] In this embodiment, while the adjustment plate 41 drives the guide body 1 to move laterally, one side of the first dovetail platform 12 at the bottom of the guide body 1 slides along the dovetail half groove 25 on the adjustment seat 2 to increase the stability of the guide body 1 during movement, and when the guide body 1 moves to the required centering position, the clamping plate 8 is used to press the other side of the first dovetail platform 12 to fix the guide body 1 on the adjustment seat 2 to prevent the guide body 1 from being offset during the steel passing process and causing product quality problems.

[0041] Specifically, the dovetail half groove 25 is located on the side of the adjustment seat 2 close to the nose cone 14 of the guide body 1, and the dovetail half groove 25 is provided with an avoidance opening running through the front and back to avoid the nose cone 14 on the guide body 1, avoiding position interference when installing the guide body 1, and helping to reduce the overall height of the guide device.

[0042] As a specific embodiment of the guide device for high-speed wire rolling mill provided by the utility model, see Figure 1 or Figure 3 The adjustment seat 2 is provided with an inverted T-shaped groove 27 extending along the direction of the first dovetail platform 12. A clamping bolt 28 that passes through the clamping plate 8 is slidably connected in the inverted T-shaped groove 27. The outer peripheral thread of the clamping bolt 28 is sleeved with a locking nut 29. The locking nut 29 is used to push the clamping plate 8 to clamp the first dovetail platform 12.

[0043] In this embodiment, one end wall of the adjustment base 2 (the end wall opposite to the end wall connected to the locking bolt 24) is inclined and coplanar or parallel to the inclined surface of the first dovetail platform 12. The pressure plate 8 has two pressing end surfaces, respectively configured to abut the inclined surface of the first dovetail platform 12 and the inclined end wall of the adjustment base 2. By tightening the locking nut 29, the pressure plate 8 is pushed toward the side of the adjustment base 2, thereby simultaneously pressing the first dovetail platform 12 and the adjustment base 2, thereby achieving the installation and fixation of the guide body 1.

[0044] Specifically, the clamping bolt 28 slides in conjunction with the inverted T-shaped slot 27, enabling the clamping bolt 28 to drive the clamping plate 8 to move along the direction of the first dovetail platform 12. When installing the guide body 1, the clamping plate 8 is first brought into contact with the first dovetail platform 12 by rotating the locking nut 29, but not into contact. At this point, the clamping end surface of the clamping plate 8 cooperates with the dovetail half-slot 25 on the adjustment seat 2 to form a full dovetail slot, which is used to stabilize the movement of the guide body 1. When the guide body 1 is adjusted, the clamping bolt 28 is used to drive the clamping plate 8 and the locking nut 29 to move until the contact area between the clamping plate 8 and the first dovetail platform 12 is maximized. The locking nut 29 is then tightened to secure the clamping plate 8 against the first dovetail platform 12, achieving a secure connection between the guide body 1 and the adjustment seat 2.

[0045] As a specific embodiment of the guide device for high-speed wire rolling mill provided by the utility model, see Figure 1 and Figure 8 The second adjustment component 5 includes a rack 22, a driving gear 51 and an adjusting handwheel 52. The rack 22 is connected to the bottom of the adjustment seat 2 and extends along the running direction of the rolled piece 10. The driving gear 51 is rotatably connected to the mounting seat 3 and meshes with the rack 22. The adjusting handwheel 52 is connected to the driving gear 51 and is located on the outside of the mounting seat 3.

[0046] After the lateral position adjustment of the guide body 1 is completed, the longitudinal position of the guide body 1 needs to be adjusted, that is, the distance between the nose cone 14 of the guide body 1 and the roller inlet along the running direction of the rolled workpiece 10 needs to be adjusted. At this time, the guide body 1 needs to be moved longitudinally along the running direction of the rolled workpiece 10. In this embodiment, the driving gear 51 is rotated by turning the adjustment handwheel 52, and the driving gear 51 drives the rack 22 to translate along the running direction of the rolled workpiece 10, thereby achieving the longitudinal movement of the adjustment base 2 and the upper guide body 1.

[0047] As a specific embodiment of the guide device for high-speed wire rolling mill provided by the utility model, see Figure 8 The adjusting hand wheel 52 is connected to the driving gear 51 through a transmission gear set. The transmission gear set includes a driven gear 54 coaxially arranged with the driving gear 51 and a driving gear 53 meshing with the driven gear 54. The driving gear 53 is rotatably connected to the mounting base 3 through a gear shaft 55, and the adjusting hand wheel 52 is connected to the outer end of the gear shaft 55.

[0048] In this embodiment, the adjusting hand wheel 52 drives the driving gear 53 to rotate, which in turn drives the driven gear 54 and the drive gear 51 to rotate synchronously, and the drive gear 51 in turn drives the rack 22 to translate. Furthermore, by rationally setting the transmission ratios between the driving gear 53, the driven gear 54, and the drive gear 51, a labor-saving adjustment method is achieved, allowing the operator to easily rotate the adjusting hand wheel 52 to achieve stable longitudinal translation of the guide body 1, thereby improving the practicality of the guide device.

[0049] As a specific embodiment of the guide device for high-speed wire rolling mill provided by the utility model, see Figure 3 、 Figure 4 and Figure 8 The first locking assembly 6 and the second locking assembly 7 both include a locking block 61 and a locking handle 62. The locking block 61 is connected to the outer side of the fixing plate 23 or the mounting seat 3 and is used to be sleeved on the outer periphery of the adjusting bolt 42 or the gear shaft 55. The locking block 61 is provided with a notch 611 set through the side wall of the locking block 61. The locking handle 62 is set through the notch 611 and is threadedly connected to the locking block 61, and is used to drive the notch 611 to retract so that the locking block 61 can tightly hold the adjusting bolt 42 or the gear shaft 55.

[0050] In this embodiment, the first locking assembly 6 locks the adjustment bolt 42 to lock the position of the adjustment plate 41, thereby fixing the lateral position of the guide body 1. The second locking assembly 7 locks the gear shaft 55 to lock the position of the adjustment seat 2, thereby fixing the longitudinal position of the guide body 1. Simultaneously, the locking action of the locking bolt 24 on the adjustment plate 41 ensures the online centering position of the guide body 1. When replacing the guide body 1, the guide body 1 can be disassembled by simply removing the pressure plate 8 and sliding the guide body 1 along the positioning groove 11 toward the rear end of the adjustment seat 2. Once the guide body 1 is offline aligned, the guide body 1 can be reinstalled online by utilizing the engagement of the positioning groove 11 with the upper positioning boss 411 and the pressure of the pressure plate 8. This eliminates the need for online centering adjustment of the guide body 1 using the first and second adjustment assemblies 4 and 5. This significantly shortens the installation time of the guide body 1, improves installation efficiency, and ensures installation accuracy and product quality.

[0051] Specifically, by rotating the locking handle 62, the part of the locking block 61 located on one side of the notch 611 gradually moves toward the other side of the notch 611, so that the notch 611 is closed so that the locking block 61 is tightly embraced by the outer periphery of the adjusting bolt 42 or the gear shaft 55, so that the adjusting bolt 42 or the gear shaft 55 is in a stably locked state.

[0052] As a specific embodiment of the guide device for high-speed wire rolling mill provided by the utility model, see Figure 3 The bottom of the adjustment seat 2 is provided with a second dovetail platform 26 extending along the running direction of the rolled piece 10, and the mounting seat 3 is provided with a dovetail groove that slides with the second dovetail platform 26.

[0053] In this embodiment, the sliding cooperation between the second dovetail platform 26 and the dovetail groove not only guides the stable sliding of the adjustment seat 2 along the mounting seat 3, but also ensures the effective connection between the adjustment seat 2 and the mounting seat 3, thereby improving the stability of the guide device.

[0054] The mounting seat 3 is further provided with a mounting base plate, and the mounting base plate is provided with mounting holes to facilitate the connection between the mounting seat 3 and the rolling mill equipment, thereby achieving fixed installation of the guide device.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
