A quick-release exit guide table device for rolling mills

Abstract

This utility model provides a quick-release exit guide table device for rolling mills, including a guide table body and multiple guide components arranged side-by-side along the length of the guide table body. Each guide component includes a wear-resistant component, a first positioning component, a second positioning component, and a groove, an installation space, a first through hole, and a second through hole formed on the guide table body. The wear-resistant component has a positioning through hole and is connected to the groove. The second positioning component is connected to the guide table body and is movably arranged along the length of the guide table body. One end of the second positioning component passes through the second through hole and abuts against the wear-resistant component. This changes the arrangement of the wear-resistant component from horizontal to vertical, thus changing the surface contact with the rolled steel strip head to line contact. It eliminates the risk of horizontal peeling, causing only minor wear, and prevents the rolled steel strip head from being unable to move forward due to insertion. At the same time, the wear-resistant component achieves double locking under the action of the positioning component, ensuring safety and reliability.

Description

Technical Field

[0001] This utility model relates to the field of steel rolling processing technology, and in particular to a quick-release exit guide table device for rolling mills. Background Technology

[0002] Current technology widely uses non-metallic materials as exit guides to reduce the chance of product abrasion. Theoretically, the direction of the strip head can be controlled during rolling, but in practice, there are many opportunities for the strip head to point downwards. Repeated impacts on the guide surface will cause pitting and roughening. This is mainly determined by the structural characteristics of this non-metallic material. Because this material is mostly made of several layers of fabric bonded and cured with a fixed amount of resin, its layered structure is obvious. This is a significant disadvantage of this material: it is easiest to peel off in the horizontal plane, while the integrity of other planes is significantly better than in the horizontal plane, just as lifting a piece of cloth is easier than tearing it. Therefore, under impact and high temperature, its adhesive strength decreases, and it is easy for layers to be inserted and peeled off one by one. After repeated exposure, the layers are inserted and flipped up but do not fall off, which will cause the strip head to bend downwards, affecting the strip threading, and even directly preventing the strip head from moving forward and causing steel to pile up.

[0003] Therefore, it is necessary to propose a quick-release exit guide device for rolling mills to solve or at least alleviate the above-mentioned defects. Utility Model Content

[0033] Please see the appendix Figure 1-6 The present invention provides a quick-release exit guide table device for a rolling mill, comprising a guide table body 10 and a plurality of guide units 20 arranged side by side along the length direction of the guide table body 10. The specific scheme is as follows:

[0034] Each guide unit 20 includes a wear-resistant component 210, a first positioning component 220, a second positioning component 230, and a groove 110, an installation space 120, a first through hole 130, and a second through hole 140 formed on the guide body 10. The wear-resistant component 210 has a positioning through hole 2121 corresponding to the first through hole 130. The wear-resistant component 210 passes through the first through hole 130 and the positioning through hole 2121 through the first positioning component 220 to connect to the groove 110. The second positioning component 230 is connected to the guide body 10 and is movably arranged along the length direction of the guide body 10. One end of the second positioning component 230 passes through the second through hole 140 and abuts against the wear-resistant component 210.

[0035] Specifically, the quick-release exit guide table device for rolling mills in this application includes a guide table body 10 and multiple guide units 20. The guide table body 10 is the main body of the entire device and serves as the exit guide table for rolling. Multiple guide units 20 are arranged side by side along the length of the guide table body 10 to form a guide surface, facilitating the guidance of rolling. Preferably, the number of guide units 20 is ten, which can be selected by those skilled in the art according to actual needs. Each guide unit 20 specifically includes a wear-resistant component 210, a first positioning component 220, a second positioning component 230, and a groove 110, an installation space 120, and a third positioning component 230 formed on the guide table body 10. The guide plate has a through hole 130 and a second through hole 140. The wear-resistant component 210 is a wear-resistant part that mainly contacts the strip head of the rolled steel. In order to reduce the chance of product scratches while guiding, a groove 110 is provided on the guide plate body 10 for the installation of the wear-resistant component 210, so that each groove 110 is provided with a corresponding wear-resistant component 210. In this way, the wear-resistant part that was originally placed horizontally in the prior art is changed to be inserted vertically into the groove 110 in this application. The multiple wear-resistant components 210 form a guide wear-resistant surface. However, when the strip head contacts the wear-resistant component 210, it is mainly in line contact, and there will be no phenomenon of layer peeling caused by insertion into the wear-resistant part.

[0036] The first positioning component 220 and the second positioning component 230 are used to double lock the wear-resistant component 210, thereby preventing the wear-resistant component 210 from being squeezed and deviating or falling off when in contact with the rolled steel strip head. Therefore, the installation space 120 is required. The installation space 120 is used for installing the first positioning component 220 and the second positioning component 230, while the first through hole 130 and the second through hole 140 are respectively used for the first positioning component 220 and the second positioning component 230 to pass through. The wear-resistant component 210 has a hole that connects with the first positioning component 220. The positioning through hole 2121 is correspondingly provided with the through hole 130. Here, "correspondingly provided" means that the first through hole 130 and the positioning through hole 2121 have the same size and shape and are set on the same axis. In this way, after the first positioning component 220 passes through, the wear-resistant component 210 is locked and positioned by the first positioning component 220, so that it cannot be easily removed vertically. The second positioning component 230 passes through the second through hole 140 and abuts against the wear-resistant component 210, thereby restricting the movement of the wear-resistant component 210 along the length direction of the guide body 10 by pressing the wear-resistant component 210, and preventing loosening.

[0037] In a preferred embodiment of the present invention, the wear-resistant component 210 includes a wear-resistant strip 211, which is connected to the groove 110, and the middle part of the wear-resistant strip 211 is provided with a slot 2111 for engaging with the first positioning component 220.

[0038] It should be noted that the wear-resistant strip 211 can be made of non-metallic materials, such as plywood, which can reduce wear on the rolled steel. The wear-resistant strip 211 has a groove 2111 in the middle. When the wear-resistant strip 211 is installed after the first positioning component 220 is installed, the groove 2111 of the wear-resistant strip 211 can be aligned with the first positioning component 220 to achieve a through-hole locking effect, thereby locking the position of the wear-resistant strip 211. Since the position of the first positioning component 220 is fixed, the position of the wear-resistant strip 211 locked on the first positioning component 220 is also fixed and will not shift or sink due to the squeezing of the rolled steel.

[0039] In a preferred embodiment of the present invention, the wear-resistant component 210 further includes a leaf spring 212, which is built into the groove 110 and connected between the bottom of the wear-resistant strip 211 and the guide body 10, and the positioning through hole 2121 is formed in the middle of the leaf spring 212.

[0040] It should be noted that the leaf spring 212 provides flexible support and can reduce the wear of the wear-resistant strip 211 to a certain extent. At the same time, the elastic support provides adaptive load support for the wear-resistant strip 211, which is more economical than rigid support. Therefore, it is connected between the bottom of the wear-resistant strip 211 and the guide body 10. The middle part has the positioning through hole 2121 for the first positioning component 220 to pass through, so that the wear-resistant strip 211 still contacts the leaf spring 212 first after being squeezed, thus achieving the effect of flexible support.

[0041] In a preferred embodiment of the present invention, the installation space 120 includes a first hole 121 and a second hole 122. The first hole 121 and the second hole 122 are arranged at intervals along the width direction of the guide body 10. The first through hole 130 communicates with the first hole 121, and the second through hole 140 communicates with the second hole 122.

[0042] It is worth noting that the first hole 121 is used for the installation of the first positioning component 220. Therefore, the first through hole 130 is connected to the first hole 121. After one end of the first positioning component 220 passes through the first through hole 130, the other end falls into the first hole 121. Similarly, the second hole 122 is used for the installation of the second positioning component 230. Therefore, the second through hole 140 is connected to the second hole 122. After one end of the second positioning component 230 passes through the second through hole 140 and abuts against the wear-resistant strip 211, the second positioning component 230 is installed in the second hole 122.

[0043] In a preferred embodiment of the present invention, the first positioning component 220 includes a fixed-distance pin 221 and two nuts 222. Two opposing first through holes 130 are provided on both sides of the groove 110. The end of the fixed-distance pin 221 passes through the first through hole 130 and the positioning through hole 2121 and extends into the first hole 121. The nuts 222 are connected to the end of the fixed-distance pin 221 and abut against the side wall of the guide body 10.

[0044] It is worth noting that the combination of the fixed-distance pin 221 and the nut 222 facilitates installation. After the fixed-distance pin 221 passes through, the leaf spring 212 is installed on the fixed-distance pin 221, and the wear-resistant strip 211 is simultaneously locked above it through the slot 2111. The nuts 222 are then connected to both ends of the fixed-distance pin 221 and tightened until they abut against the side wall of the guide body 10, thereby fixing the fixed-distance pin 221, fixing the position of the wear-resistant strip 211, and fixing the distance between the wear-resistant strip 211 and the bottom of the groove 110, achieving a fixed-distance positioning effect.

[0045] Further, the second positioning component 230 includes a portal bracket 231, a spring 232, a pin 233, a pad 234, and a handle 235. The portal bracket 231 is connected to the side wall of the guide body 10. The pad 234 is connected to the pin 233 and is disposed near the first end of the pin 233. The pad 234 is matched with the second through hole 140. The spring 232 is connected between the pad 234 and the portal bracket 231. The first end of the pin 233 is used to abut against the wear-resistant strip 211. The second end of the pin 233 extends out of the portal bracket 231 and is movably disposed along the length direction of the guide body 10. The handle 235 is connected to the second end of the pin 233.

[0046] It should be noted that most of the second positioning components 230 are installed in the second hole 122, while one of the second positioning components 230 at one end of the guide platform body 10 is located on the outer wall of the guide platform body 10, considering that there are no holes on the outside. For details, please refer to the appendix. Figure 1 The portal frame 231 is used for installing other components. The pin 233 is the main moving component. Its first end is used to hold the wear-resistant strip 211 for positioning, while its second end extends out of the portal frame 231 to facilitate the installation of the handle 235. The handle 235 passes through the second end of the pin 233 for easy operation by technicians. The pad 234 is used to cooperate with the spring 232. In the initial state, the preload of the spring 232 pushes the pad 234, forming the effect of the entire pin 233 holding the wear-resistant strip 211. When it is necessary to disassemble and replace the wear-resistant strip 211, the handle 235 can be used to pull the pin 233. At this time, the spring 232 is compressed, and the pin 233 moves away from the wear-resistant strip 211 to cancel the positioning effect. After the wear-resistant strip 211 is installed or replaced, the pin 233 is released and continues to achieve the positioning effect of pressing and holding with the action of the spring 232.

[0047] Furthermore, the leaf spring 212 is bent in the direction from the positioning through hole 2121 to both ends.

[0048] It should be understood that the bent leaf spring 212 can better distribute stress, making the stress more uniform along the entire length of the spring 232. This helps to improve the load-bearing capacity of the spring 232 and reduce local stress concentration. Moreover, the bent leaf spring 212 can provide a larger range of elastic deformation in a limited space, which is very advantageous for space-constrained applications, such as the groove 110 of this application. In the embodiments of this application, the plywood has a certain deformation capacity. After the rolled steel passes through the end of the plywood, it can press down on the plywood slightly. The end of the plywood then presses down on the contacting leaf spring 212 and is supported by the flexible support effect of the leaf spring 212.

[0049] Furthermore, the first through hole 130 is an elongated hole extending vertically.

[0050] It should be noted that the elongated hole extends vertically, which facilitates the removal of the wear-resistant strip 211. By slightly loosening the nut 222, the entire spacer pin 221 can be pressed downwards, thereby causing the leaf spring 212 (positioning through hole 2121) to disengage from the groove 2111 of the wear-resistant strip 211, thus canceling the positioning effect and allowing the wear-resistant strip 211 to be replaced. In summary, when replacing the wear-resistant strip 211, simply pull out the pin 233, then slightly loosen the nut 222 and press down on the spacer pin 221 to pull out the wear-resistant strip 211, insert the new wear-resistant strip 211, and then restore the two positioning components. The operation is convenient and quick.

[0051] Furthermore, the wear-resistant strip 211 is inclined at both ends of its top surface along its length.

[0052] It should be noted that this design facilitates contact between the strip head and the substrate during introduction, preventing damage to the product from right-angle impacts.

[0053] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
