Description

Technical Field

[0001] This utility model belongs to the field of metal pressure processing technology and is a high-stability short stress line rolling mill guide slide locking device. Background Technology

[0002] Currently, the guide slide installation method for short-stress line rolling mills generally consists of a slide, a moving lead screw, and a locking triangular iron block. The slide is locked using a one-way locking method. However, the current guide slide structure is prone to problems during locking, such as slide tilting, loosening of the locking nut, insufficient locking force leading to incomplete locking, and slide jamming.

[0003] The deficiencies in the guide slide mechanism directly lead to problems such as guide tilting and loosening, affecting the dimensional accuracy and surface quality of rolled products, and even causing serious malfunctions that prevent production from proceeding. Utility Model Content

[0007] Preferably, the guide mounting slide is mounted on the mill crossbeam, wherein the surface of the mill crossbeam is provided with a transverse screw mounting hole, and the transverse screw mounting hole is used to mount the slide transverse screw with a rolling bearing;

[0008] The mill crossbeam has a guide mounting slide sliding surface. The guide mounting slide is fixed to the short stress line mill by four crossbeam mounting holes with a small clearance fit with this surface. The crossbeam mounting holes are waist-shaped holes, which have the ability to adjust the vertical stroke. Adjusting bolts are installed on the crossbeam height adjustment bolt mounting holes.

[0009] The corresponding hangers are installed on the mill crossbeam. The height is adjusted by adjusting the height bolts. After adjustment, the crossbeam mounting bolts on each crossbeam mounting hole are tightened to lock the mill crossbeam onto the mill.

[0010] Preferably, the slide block transverse lead screw is the driving mechanism for the transverse movement of the slide block. The slide block transverse lead screw consists of a lead screw mounting surface and a lead screw drive thread. The lead screw mounting surface is fitted with a bearing and installed in the transverse lead screw mounting hole. The lead screw surface and the transverse slider cooperate to realize the left and right sliding of the slide block transverse lead screw.

[0011] Preferably, the mill crossbeam has a slider mounting slot, which cooperates with the guide mounting slide base plate.

[0012] Preferably, the guide mounting slide base plate has a mounting hole for mounting on the guide mounting slide by bolts, the outer locking block is installed in the first outer locking block mounting hole formed by the guide mounting slide base plate and the guide mounting slide, and the inner locking block is installed in the inner locking block mounting hole formed by the guide mounting slide base plate and the guide mounting slide.

[0013] Preferably, the outer locking block has a locking bolt hole for installing a locking bolt, the size of the locking bolt hole is clearance-fitted with the locking bolt, and the outer locking buckle mounting hole is a threaded hole;

[0014] The outer locking buckle mounting hole and the second outer locking block mounting hole in the outer locking block buckle cooperate to combine the outer locking block buckle and the outer locking block into a whole. In the locked state, the guide slider pressing surface of the outer locking block contacts the guide mounting slide, pressing and fixing the guide mounting slide onto the mill crossbeam.

[0015] Preferably, the outer locking block buckle is assembled by bolts connecting the second outer locking block mounting hole and the outer locking buckle mounting hole. The size of the locking bolt groove mounting surface is smaller than the size of the locking bolt mounting hole, and the locking bolt groove mounting surface and the bolt slot in the locking bolt are fitted with a clearance.

[0016] The locking bolt hole engages with the threaded surface of the locking bolt, and the inner locking block and the inclined surface of the mill crossbeam press against the locking surface of the inner locking block in the locked state to achieve locking.

[0017] Preferably, the threaded surface of the locking bolt engages with the threaded hole of the locking bolt in the inner locking block, driving the inner locking block to move inward or outward; the locking bolt slot drives the outer locking block to move inward or outward through the outer locking block's latch; the main function of the locking bolt head is to rotate the locking bolt, and it can also be used to strike the locking bolt.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This high-stability short-stress-line mill guide slide locking device features a bidirectional synchronous locking design, solving the problems of tilting and loosening. Unlike the traditional unidirectional locking method, it achieves uniform force distribution on the guide slide on the mill crossbeam through the bidirectional synchronous pressing mechanism of the inner and outer locking blocks. When the locking bolts rotate, the inner and outer locking blocks act simultaneously on different contact surfaces of the slide, forming a stable three-point support structure and completely eliminating the risk of slide tilting.

[0020] 2. This high-stability short-stress-line rolling mill guide slide locking device features adaptive inclined surface matching technology, enabling automatic alignment. The two inclined surfaces at the bottom of the guide frame are complementary to the inclinations of the inner and outer locking blocks. During the locking process, the guide mounting slide can automatically correct installation deviations through the automatic sliding of the inclined surfaces, eliminating the need for manual calibration. Simultaneously, the crossbeam mounting hole is designed as an oblong hole, which, in conjunction with the adjusting bolt in the crossbeam height adjusting bolt mounting hole, allows for vertical height adjustment, making it compatible with different rolling mill models and reducing the types of spare parts.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0035] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0036] Please see Figure 1-9 This utility model provides a technical solution: a high-stability short-stress-line rolling mill guide slide locking device, comprising a rolling mill crossbeam 1, a guide mounting slide 2, a slide transverse sliding screw 3, an outer locking block buckle 4, a locking bolt 5, an outer locking block 6, a guide mounting slide base plate 7, an inner locking block 8, and a baffle 9.

[0037] The bottom plate 7 of the guide slide is on the guide slide 2. The bottom plate 7 of the guide slide is positioned by the keyway of the guide slide 2. The guide slide 2 has guide dovetail mounting holes for mounting dovetail pressure plates. There is a baffle 9 on the inner side of the guide slide 2. The bottom of the bottom plate 7 of the guide slide has a first outer locking block mounting hole 10 and an inner locking block mounting hole 11.

[0038] The guide mounting slide 2 is installed on the mill crossbeam 1. The surface of the mill crossbeam 1 has a transverse screw mounting hole 12. The transverse screw mounting hole 12 is matched with the rolling bearing mounting slide transverse screw 3. The mill crossbeam 1 has a guide mounting slide sliding surface. The guide mounting slide 2 is fitted with this surface with a small clearance and is fixed to the short stress line mill by four crossbeam mounting holes 13. The crossbeam mounting holes 13 are waist-shaped holes with vertical adjustment stroke. Adjusting bolts are installed on the crossbeam height adjustment bolt mounting holes 14. Corresponding hangers are installed on the mill crossbeam 1 and the height is adjusted by adjusting the height bolts. After adjustment, the crossbeam mounting bolts on the crossbeam mounting holes 13 are tightened to lock the mill crossbeam 1.

[0039] The slide block transverse lead screw 3 is the driving mechanism for the transverse movement of the slide block. The slide block transverse lead screw 3 consists of a lead screw mounting surface and a lead screw drive thread. The lead screw mounting surface is fitted with a bearing and installed in the transverse lead screw mounting hole 12. The lead screw surface and the transverse slider cooperate to realize the left and right sliding of the slide block transverse lead screw 3.

[0040] The mill crossbeam 1 has a slider mounting slot 19, which cooperates with the guide mounting slide base plate 7.

[0041] The guide mounting slide base plate 7 has a mounting hole that is bolted to the guide mounting slide 2. The outer locking block 6 is installed in the first outer locking block mounting hole 10 formed by the guide mounting slide base plate 7 and the guide mounting slide 2. The inner locking block 8 is installed in the inner locking block mounting hole 11 formed by the guide mounting slide base plate 7 and the guide mounting slide 2.

[0042] The outer locking block 6 has a locking bolt hole 15 for installing the locking bolt 5. The size of the locking bolt hole 15 is clearance-fitted with the locking bolt 5. The outer locking buckle mounting hole 16 is a threaded hole. The outer locking buckle mounting hole 16 and the second outer locking block mounting hole 18 in the outer locking block buckle 4 cooperate to combine the outer locking block buckle 4 and the outer locking block 6 into a whole. In the locked state, the guide slider pressing surface of the outer locking block 6 contacts the guide mounting slide 2, pressing and fixing the guide mounting slide 2 onto the mill crossbeam 1. After the bolts are tightened to the inclined surface of the mill crossbeam 1, it can be attached to the inclined surface of the mill crossbeam 1. By strictly controlling the size of the guide slider pressing surface of the mating surface of the mill crossbeam 1 and the surface of the outer locking block 6, when locking, the guide slide pressing surface presses the guide mounting slide 2 while the mating surface of the mill crossbeam 1 presses the mill crossbeam 1.

[0043] The outer locking block buckle 4 is connected by bolts to the second outer locking block mounting hole 18 and the outer locking buckle mounting hole 16. The size of the locking bolt groove mounting surface 17 is smaller than the size of the locking bolt 5 mounting hole. The locking bolt groove mounting surface 17 locks the bolt groove in the locking bolt 5 with clearance fit. The locking bolt hole 15 engages with the locking bolt thread surface of the locking bolt 5. The inner locking block 8 and the mill crossbeam 1 are pressed together by the inclined surface of the inner locking block 8 in the locked state to achieve locking.

[0044] The threaded surface of the locking bolt 5 engages with the threaded hole of the locking bolt 5 in the inner locking block 8, driving the inner locking block 8 to move inward or outward; the locking bolt slot drives the outer locking block 6 to move inward or outward through the outer locking block buckle 4; the main function of the screw head of the locking bolt 5 is to rotate the locking bolt 5, and it can also be used to strike the locking bolt 5.

[0045] When using this device, the locking and unlocking operations after the mechanism is assembled are as follows:

[0046] Locking operation: Rotate the locking bolt 5. Because the locking bolt hole 15 and the locking bolt thread surface engage, the total length of the inner locking block 8 and the locking bolt 5 is reduced. At the same time, the locking bolt head squeezes the combination formed by the outer locking block buckle 4 and the outer locking block 6, reducing the distance between the inner locking block 8 and the outer locking block 6. Finally, the inner locking block 8 is fixed to the mill crossbeam 1 by pressing the inner locking block 8 with the mating surface of the crossbeam inclined surface. The outer locking block 6 is pressed with the outer locking block 6 with the mating surface of the crossbeam inclined surface, and at the same time, the guide slide pressing surface is pressed with the guide slide, thereby locking the guide mounting slide 2 on the crossbeam without any possibility of shaking.

[0047] Loosening operation: Rotate the locking bolt 5. Because the locking bolt hole 15 and the locking bolt thread surface are engaged, the total length of the inner locking block 8 and the locking bolt 5 increases. In this case, two situations may occur. One is that the outer locking block 6 is not loosened and is still tightly attached to the crossbeam. At this time, the inner locking block 8 moves inward and away from the crossbeam, and the inner locking block 8 is loosened. When the inner locking block 8 contacts the baffle 9, the inner locking block 8 can no longer move inward. At this time, the locking bolt 5 moves outward. The locking bolt slot on the locking bolt 5 drives the outer locking block buckle 4 to move outward. The outer locking block buckle 4 drives the outer locking block 6 to move outward. At this time, the mating surface of the outer locking block 6 with the crossbeam moves away from the locking surface of the outer locking block 6. At the same time, the pressing surface of the guide slide moves away from the guide slide, thereby realizing the loosening of the guide slide and the crossbeam.

[0048] In another scenario, the inner locking block 8 remains attached to the crossbeam without being released. In this case, the locking bolt slot on the locking bolt 5 causes the outer locking block buckle 4 to move outward, which in turn causes the outer locking block 6 to move outward. At this point, the mating surface of the outer locking block 6 with the crossbeam moves away from the locking surface of the outer locking block 6, and the pressing surface of the guide slide moves away from the guide slide, thus releasing the outer locking block 6. Then, simply tap the head of the locking bolt 5 to move it inward. The locking bolt 5 causes the inner locking block 8 to move inward, disengaging the mating surface of the inner locking block 8 with the inclined surface of the crossbeam from the locking surface of the inner locking block 8, thus releasing the guide mounting slide 2 from the crossbeam. At this point, simply rotate the slide transverse screw 3 to move the guide mounting slide 2 transversely, thus moving the guide.

[0049] The bottom of the guide frame has two inclined surfaces that serve as locking surfaces for the slide block. The inclination of the inclined surfaces is complementary to the inclination of the inner locking block 8 and the outer locking block 6.

[0050] The inner locking block 8 and the outer locking block 6 have the same slope. The inner locking block 8 has a threaded hole that meshes with the locking bolt 5. The outer locking block 6 has a through hole, the size of which is clearance-fitted with the smooth surface of the locking bolt 5. A baffle 9 is installed at the position of the through hole, and the inner hole size of the baffle 9 is clearance-fitted with the concave surface of the locking bolt 5.

[0051] One end of the locking bolt 5 has a threaded surface, and the other end is threaded near the bolt's hexagonal cap, driving it to move outward and press against the inner inclined surface at the bottom of the crossbeam. The outer locking block 6 is pressed inward by the bolt cap and has a concave surface. The diameter of the concave surface is smaller than the diameter of the smooth surface, and the diameter of the concave surface is in clearance fit with the inner hole of the upper baffle 9 of the outer locking block 6.

[0052] The outer locking block 6 has a wing. When locking, the wing presses against the slider and simultaneously contacts the inclined surface at the bottom of the crossbeam to lock it in place, thereby locking the slide block onto the crossbeam.

[0053] When the locking bolt 5 is tightened, the inner locking block 8 is screwed in and pressed against the outer inclined surface at the bottom of the crossbeam to achieve locking. When loosened, in one case, the adhesion force between the outer slider and the inclined surface is greater than the adhesion force between the inner slider and the inclined surface of the crossbeam. In this case, the inner locking block 8 moves inward under the drive of the thread, away from the inner inclined surface of the crossbeam, and can no longer move when it reaches the baffle 9, thus pushing the bolt outward. The bolt groove, through the outer locking block buckle 4, disengages the outer slider from the lower inclined surface of the crossbeam. In another case, the adhesion force between the inner slider and the locking inclined surface is greater than the adhesion force between the outer slider and the inclined surface of the crossbeam. In this case, the outer slider moves outward, and the groove of the locking bolt 5, through the outer locking block 6, disengages the outer locking block 6 from the lower inclined surface of the crossbeam. Simply tapping the locking bolt 5 will disengage the inner slider from the inclined surface.

[0054] Furthermore, the bidirectional synchronous locking design solves the problems of tilting and loosening. Unlike the traditional unidirectional locking method, the bidirectional synchronous pressing mechanism of the inner locking block 8 and the outer locking block 6 achieves uniform force on the guide mounting slide 2 on the mill crossbeam 1. When the locking bolt 5 rotates, the inner and outer locking blocks act on different contact surfaces of the slide at the same time, forming a stable three-point support structure and completely eliminating the risk of slide tilting.

[0055] The adaptive inclined surface matching technology enables automatic alignment. The two inclined surfaces at the bottom of the guide frame are complementary to the inclinations of the inner locking block 8 and the outer locking block 6. During the locking process, the guide mounting slide 2 can automatically correct the installation deviation through the sliding of the inclined surface without the need for manual calibration. At the same time, the crossbeam mounting hole 13 is designed as an oblong hole. With the adjustment bolt in the crossbeam height adjustment bolt mounting hole 14, the vertical height can be adjusted, which is compatible with different types of rolling mills and reduces the types of spare parts.

[0056] Structural Description: Rolling Mill Crossbeam 1: This is the basic support structure of the entire device. The surface has horizontal sliding screw mounting holes 12 for mounting the slide horizontal sliding screw 3. The guide mounting slide sliding surface has a small clearance fit with the guide mounting slide 2. It is fixed to the short stress line rolling mill through the crossbeam mounting holes 13, and the height can be adjusted by the adjusting bolts on the crossbeam height adjusting bolt mounting holes 14.

[0057] Guide mounting slide 2: Used to install the guide, it is positioned with the guide mounting slide base plate 7 through the keyway, and has a baffle 9 on the inner side. It is installed on the mill crossbeam 1 and can be moved laterally under the drive of the slide lateral movement screw 3, thereby driving the guide to move laterally.

[0058] Slide lateral sliding screw 3: As the driving mechanism for the lateral movement of the slide, it consists of a screw mounting surface and a screw transmission thread. The screw mounting surface is fitted with a bearing and installed in the lateral sliding screw mounting hole 12. The left and right sliding of the guide mounting slide 2 is realized through the cooperation of the screw surface and the lateral sliding block.

[0059] External locking block buckle 4: It is connected to the external locking block 6 by bolts through the second external locking block mounting hole 18 and the external locking buckle mounting hole 16 to form a whole. Under the action of the locking bolt 5, it drives the external locking block 6 to move inward or outward.

[0060] Locking bolt 5: When rotated, its threaded surface engages with the locking bolt hole 15 in the inner locking block 8, driving the inner locking block 8 to move. At the same time, its slot drives the outer locking block 6 to move through the outer locking block buckle 4, realizing the locking and unlocking operation of the device. The screw head can be used for rotation and tapping.

[0061] Outer locking block 6: Installed in the first outer locking block mounting hole 10 formed by the guide mounting slide base plate 7 and the guide mounting slide 2, it has a locking bolt hole 15 and an outer locking buckle mounting hole 16. In the locked state, its guide slider pressing surface contacts the slide, pressing and fixing the guide mounting slide 2 onto the mill crossbeam 1. When locked, the wing edge presses the slider and contacts the bottom inclined surface of the crossbeam for locking.

[0062] Guide mounting slide base plate 7: Installed on guide mounting slide 2 and connected by bolts, it has a first outer locking block mounting hole 10 and an inner locking block mounting hole 11, which are used to install the outer locking block 6 and the inner locking block 8 respectively, and cooperate with the slider mounting slot 19 on the mill crossbeam;

[0063] Inner locking block 8: Installed in the inner locking block mounting hole 11 formed by the guide mounting slide base plate and the guide mounting slide 2, and pressed against the locking surface of the inner locking block 8 by the inclined surface of the mill crossbeam 1 in the locked state to achieve locking, and can move inward or outward by engaging with the thread of the locking bolt 5;

[0064] Baffle 9: Installed on the inner side of the guide mounting slide 2 and at the through hole position of the outer locking block 6, it is used to restrict the movement of the inner locking block 8. When the inner locking block 8 moves to the contact position, it prevents the inner locking block 8 from continuing to move inward. At the same time, its inner hole is in clearance fit with the concave surface of the locking bolt 5.

[0065] Crossbeam mounting hole 13: It is a waist-shaped hole, which allows the mill crossbeam 1 to have an up-and-down adjustment stroke when it is fixed to the mill. In conjunction with the adjusting bolt in the crossbeam height adjusting bolt mounting hole 14, the vertical height of the mill crossbeam 1 can be adjusted to be compatible with different models of mills and reduce the types of spare parts.

[0066] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
