[0001] This utility model relates to the field of metallurgical rolling equipment technology, and in particular to a detachable edge rolling mill guide support device that can be quickly adjusted online. Background Technology
[0002] Guide devices are used to ensure the workpiece maintains the correct orientation as it enters and exits the rolls, thereby maximizing product yield and quality. With a few exceptions, guide devices are typically required on all rolling mills. The smaller the workpiece, the more precise the machining and installation of the guide device must be. Guide devices are divided into two types: exit devices and inlet devices.
[0003] Traditional edge rolling machine guide supports are mostly integrally cast structures, which have many drawbacks. They need to be replaced as a whole after wear, resulting in high spare parts costs; height adjustment requires disassembling the eccentric shaft assembly, with each adjustment taking 40 minutes; and they are prone to steel sticking, with a rolling scar defect rate of up to 1%, affecting product quality. Utility Model Content
[0004] To address the aforementioned technical problems, a detachable guide support device for an edge rolling machine that can be quickly adjusted online is provided. The technical means employed in this invention are as follows:
[0005] A detachable guide support device for an edge rolling machine, which can be quickly adjusted online, includes a guide base and a guide support disposed below the guide base. The front and rear ends of the guide base extend outwards to form a first mounting base and a second mounting base, respectively. Both the first and second mounting bases are provided with mounting grooves for mounting the guide support. These mounting grooves are close to the guide base and have preset specifications. The first mounting base has a first bolt mounting hole and a hinge mounting hole opened horizontally. The front end of the guide support, corresponding to the position of the first mounting base, also has a guide support bolt mounting hole and a guide support hinge hole. The first mounting base has a shaft mounting hole, in which a first position fixing bolt and a hinge shaft are respectively installed.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0016] like Figure 1 As shown in the figure, this utility model discloses a detachable edge-rolling machine guide support device that can be quickly adjusted online, including a guide base 1 and a guide support 2 disposed below the guide base. The front end and rear end of the guide base extend outward to form a first mounting base 11 and a second mounting base 12, respectively. Both the first and second mounting bases are provided with mounting grooves for mounting the guide support. The mounting grooves are opened close to the guide base and have a preset specification. The first mounting base is provided with a first bolt mounting hole and a hinge shaft opened in the horizontal direction. The mounting holes are perpendicular to the guide base, not parallel to it. The front end of the guide support, corresponding to the first mounting base, also has guide support bolt mounting holes and guide support hinge mounting holes. A first position fixing bolt and a hinge 21 are installed in the first bolt mounting hole and hinge mounting hole, respectively. The second mounting base includes a longitudinally formed first screw hole, the top surface of which is located on the upper surface of the second mounting base, for installing a first bolt, which is an adjusting bolt 4. A connecting plate mounting groove is provided at the end of the second mounting base. A connecting plate 13, fixedly connected to the guide support, is installed in the connecting plate mounting groove. A second screw hole is provided at the bottom of the connecting plate mounting groove for installing a second bolt, which serves as a load-bearing bolt 3. The first mounting base has a second bolt mounting hole along a horizontal direction for installing a second position fixing bolt, which serves as a clamping bolt 6.
[0017] The aforementioned hinge pin can also be replaced with bolts of M24 or larger. The bolts have a large diameter and high strength, ensuring stable front-end support. Equipped with appropriate nuts and washers, tightening the nuts secures a tight connection between the guide support and the guide base. This connection method ensures both stability and allows the guide support to rotate within a certain range, facilitating installation and replacement.
[0018] Furthermore, the second bolt is an M16 bolt, and the length of the bolt is determined according to the thickness of the guide support and the guide base to stably support the weight of the guide support. The thread pitch is a standard pitch. Its head is a hexagonal head, which facilitates installation and disassembly using tools such as wrenches. There is a washer of a certain thickness under the head to increase the contact area with the guide support, distribute pressure, and prevent excessive local stress from damaging the components.
[0019] Furthermore, the first bolt is an M24 bolt, and the length of the bolt is determined based on the thickness of the guide support and the guide base. The head is an internal hex head, facilitating precise rotational adjustment using an internal hex wrench. By rotating the adjusting bolt, the height of the guide support can be finely adjusted, with an accuracy of ±0.5mm.
[0020] Furthermore, an anti-rotation sleeve 5 is fitted onto the outside of the first bolt for engaging with the shank and / or head of the first bolt. In operation, the anti-rotation sleeve is fixedly connected to the guide base. The anti-rotation sleeve, through its hexagonal prism structure, mates with the adjusting bolt, with its inner diameter tightly fitting the outer diameter of the adjusting bolt. The six sides fit together effectively, preventing the bolt from loosening after adjustment. The anti-rotation sleeve is made of high-strength, wear-resistant material, and its height matches the depth of the corresponding mounting hole on the guide base, ensuring stable fixation to the guide base.
[0021] The "working state" mentioned above refers to the actual production process, where the anti-rotation sleeve is fixedly connected to the guide base, and can be disassembled during maintenance or replacement of the guide support. Specific fixing methods include bolting to the corresponding mounting holes on the guide base, or fixing via welding.
[0022] Furthermore, both the first and second position fixing bolts are M16 bolts. Lateral clearances in the guide support are eliminated by pre-tightening force. During installation, a torque wrench is used to tighten the clamping bolts to the specified torque value to ensure uniform and appropriate pre-tightening force, thus guaranteeing the stability of the guide support during operation.
[0023] In this embodiment, both the first and second mounting bases are cuboids. Mounting grooves are formed near the bottom and near the guide base in their thickness direction, serving as main mounting grooves. The top of the main mounting groove is at least a certain distance from the top surfaces of the first and second mounting bases, thus forming an inverted L-shape. Furthermore, the phrase "the end of the second mounting base has a mounting groove" specifically refers to a non-penetrating mounting groove formed at a predetermined height in the vertical direction of the second mounting base, away from the second mounting base. This mounting groove is positioned close to the main mounting groove. Here, "non-penetrating" means that the end of the groove does not extend to the surface of the second mounting base near the first mounting base.
[0024] The first screw hole of the second mounting base extends from the upper surface of the second mounting base to the upper surface of the aforementioned "non-penetrating mounting groove".
[0025] The second screw hole is formed by the lower surface of the second mounting base penetrating to the lower surface of the aforementioned "non-penetrating mounting groove".
[0026] The first bolt mounting hole and hinge mounting hole are formed by extending from the surface of the first mounting base away from the guide body into the aforementioned main mounting groove of the first mounting base.
[0027] The second bolt mounting hole is a through-hole on the surface of the second mounting base away from the guide body, extending into the aforementioned main mounting groove of the second mounting base.
[0028] The specific installation process of this invention is as follows: First, place the guide support 2 to be installed in the groove opened in the first mounting base 11 and the second mounting base 12. Install the hinge shaft on the hinge shaft (or bolt) mounting hole. After passing through the first mounting base and the guide support, the angle of the front end of the guide support can be adjusted. After confirming the angle, press the front end of the guide support onto the guide base by the first position fixing bolt.
[0029] After confirming the angle, the second bolt passes through the hole from below and connects to the second mounting base. Its upper end can support the guide support. The first bolt passes through the threaded hole and rests on the top surface of the guide support. After adjusting the height of the guide support, it is necessary to ensure that the first bolt is fixed and does not rotate. That is, after adjusting the height, connect the anti-rotation sleeve to the first bolt. When adjustment is needed, the anti-rotation sleeve can be removed.
[0030] To prevent the guide support from wobbling during rolling, it is further tightened using second-position fixing bolts and first-position fixing bolts. Specifically, the second-position fixing bolts and first-position fixing bolts pass through the mounting base and press against the side of the guide support, further ensuring a stable and reliable connection between the guide support and the mounting base.
[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
