Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of rolling technology, and more specifically, to a controlled cooling and rolling device for elliptical blanks. Background Technology

[0002] Rolling is a metal processing technique in which metal billets are passed through the gap between a pair of rotating rolls (of various shapes). Due to the compression of the rolls, the cross-section of the material is reduced and the length is increased. The controlled cooling and rolling device for elliptical materials is a process equipment specifically used to produce steel with elliptical cross-sections (such as elliptical steel, elliptical tube blanks, etc.).

[0003] Traditional controlled cooling and rolling devices for elliptical blanks have the following shortcomings: In the conventional controlled cooling process, the edges (closer to the surface) of the elliptical blank cool faster because they are in more direct contact with the cooling water; while the center (core) cools slower due to the longer heat transfer path, resulting in a large temperature difference (temperature gradient) between the edges and the center. This temperature gradient can cause problems, as the difference in cooling shrinkage leads to internal stress, affecting the accuracy of subsequent processing (such as cutting and bending). Therefore, improvements are needed. Utility Model Content

[0031] like Figures 1-6 The diagram illustrates a controlled cooling and rolling device for elliptical material according to an embodiment of this disclosure. It includes a roller assembly 1, a rolling mechanism 2 disposed on the outer side of the roller assembly 1, and a side plate 201 placed on the outer side of the roller assembly 1. A first roll 202 and a second roll 203 are rotatably mounted between the inner sides of the side plate 201. A rectangular plate 208 located in front of the first roll 202 is welded to the inner side of the side plate 201. A nozzle 211 is bolted inside the rectangular plate 208. A flat elliptical nozzle 212 is formed at the bottom of the nozzle 211. Above the rectangular plate 208... A water distributor 209 is bolted on, and a water pipe 210 extending into the nozzle 211 is threaded on the output end of the water distributor 209. A water tank 3 is bolted on the outer side of the side plate 201, and a water pump 5 is welded on the top of the water tank 3. A filter mechanism 4 is provided on the outer side of the rolling mechanism 2. The input end of the water pump 5 extends into the interior of the water tank 3, and the output end of the water pump 5 passes through the filter mechanism 4 to the inner side of the rolling mechanism 2 and is threaded on the top of the water distributor 209. There are three water pipes 210 in total, and the three water pipes 210 are evenly threaded and connected to the interior of the nozzle 211.

[0032] In some examples, during use, the material is moved into the rolling mechanism 2 by the roller group 1. At this time, the servo motor 207 drives the gear 205 to rotate, which in turn drives the gear 1 204 to rotate. This causes the gear 1 204 and the gear 205 to rotate synchronously, which in turn causes the roller 1 202 and the roller 2 203 to rotate synchronously. This allows the material to be rolled between the roller 1 202 and the roller 2 203. At this time, the water pump 5 draws water from the water tank 3, which is then fed into the water distributor 209 through the filter mechanism 4. The water is then fed into the nozzle 211 through the water distributor 209 and the water pipe 210, and then sprayed out through the flat elliptical nozzle 212, so that the amount of water flowing at the center of the material is greater than the amount of water flowing at both ends of the material.

[0033] By making the water flow cover more closely to the central area of ​​the elliptical material, avoiding overcooling at the edges and insufficient cooling in the center, compared with the traditional controlled cooling and rolling device for elliptical materials, this controlled cooling and rolling device for elliptical materials increases the water flow density and speed in the center by setting a flat elliptical nozzle 212, thereby enhancing the impact cooling effect and solving the problem of uneven cooling caused by the cross-sectional shape of the elliptical material, thus avoiding overcooling and embrittlement at the edges or residual defects in the center.

[0034] like Figures 1-6 As shown, a controlled cooling and rolling device for elliptical materials is illustrated in another embodiment of this disclosure. The filtering mechanism 4 includes a filter box 401 bolted to the rear end of a side plate 201. A pull plate 402 is provided on the right side of the filter box 401, and a filter plate 403 extending into the filter box 401 is bolted to the left side of the pull plate 402. A slot 404 is provided at the right end of the filter box 401, and an insert plate 405 extending into the slot 404 is welded to the left end of the pull plate 402. A slot 410 extending into the slot 404 is provided on the outer side of the filter box 401. The interior of 405 has a movable groove 406, and an arc-shaped plate 407 extending into the slot 410 is slidably installed inside the movable groove 406. A push plate 411 is slidably installed inside the slot 404. The push plate 411 is located below the insert plate 405. A return spring 412 is elastically installed between the inner side of the push plate 411 and the bottom of the slot 404. A telescopic spring 408 is elastically installed at the bottom of the movable groove 406, and the arc-shaped plate 407 is located outside the telescopic spring 408. When the arc-shaped plate 407 is located in the slot 410, the return spring 412 is in a compressed state.

[0035] In some examples, when water flows through the filter plate 403, the water is filtered. When the filter plate 403 needs to be replaced, simply press the arc plate 407 to retract it into the movable groove 406, causing the arc plate 407 to compress the telescopic spring 408 and deform it. When the arc plate 407 is fully inserted into the movable groove 406, the return spring 412 releases its elastic potential energy to push the push plate 411 upward inside the slot 404, causing the push plate 411 to push the insert plate 405 outward, thereby disengaging the arc plate 407 from the slot 410. Then, pull the pull plate 402 to pull the insert plate 405 out of the slot 404, thus removing the filter plate 403.

[0036] like Figures 1-3As shown, a controlled cooling and rolling device for elliptical material is illustrated in another embodiment of this disclosure. Gear 1 204 and gear 2 205 are rotatably mounted on the front end of the side plate 201. The front ends of the second roll 203 and the first roll 202 are respectively bolted to the rear side of the gear 1 204 and the gear 2 205, and the gear 1 204 and the gear 2 205 mesh with each other. A U-shaped plate 206 is welded to the front side of the side plate 201. A servo motor 207 is bolted to the front side of the U-shaped plate 206, and the output end of the servo motor 207 is bolted to the front side of the gear 2 205.

[0037] In some examples, the servo motor 207 is started, which drives the gear 205 to rotate, thereby causing the gear 205 and the gear 1 to rotate synchronously, which in turn drives the roller 1 202 and the roller 2 203 to rotate synchronously to roll the material.

[0038] like Figure 6 As shown, it illustrates a controlled cooling and rolling device for elliptical material in another embodiment of the present disclosure. Limiting blocks 409 are welded to both sides of the bottom of the arc plate 407, and the limiting blocks 409 are slidably connected inside the movable groove 406.

[0039] In some examples, when the curved plate 407 slides inside the movable groove 406, the limiting block 409 slides along with the curved plate 407 inside the movable groove 406, thereby limiting the curved plate 407.

[0040] like Figures 1-5 As shown, it illustrates a controlled cooling and rolling device for elliptical material in another embodiment of the present disclosure. The number of filter plates 403 is two, and the filter hole radius of the filter plate 403 on the side closer to the water pump 5 is larger than the filter hole radius of the filter plate 403 on the other side.

[0041] In some examples, the water flow is filtered by setting two filter plates 403. The water flow first passes through the filter plate 403 with larger filter holes for initial filtration, and then enters the next filter plate 403 for secondary filtration. This reduces the filtration burden on a single filter plate 403, improves the filtration effect, and reduces the replacement frequency.

[0042] Working principle and usage process of this utility model:

[0043] In use, the material is moved into the rolling mechanism 2 by the roller group 1. At this time, the servo motor 207 drives the gear 205 to rotate, which in turn drives the gear 1 204 to rotate. This causes the gear 1 204 and the gear 205 to rotate synchronously, which in turn causes the roller 1 202 and the roller 2 203 to rotate synchronously. This allows the material to be rolled between the roller 1 202 and the roller 2 203. At this time, the water pump 5 draws water from the water tank 3 and inputs it into the water distributor 209 through the filter mechanism 4. The water distributor 209 and the water pipe 210 input the water into the nozzle 211 and then spray it out through the flat elliptical nozzle 212, so that the water flow at the center of the material is greater than the water flow at both ends of the material.

[0044] When water flows through the filter plate 403, it is filtered. When the filter plate 403 needs to be replaced, simply press the arc plate 407 to retract it into the movable groove 406. This causes the arc plate 407 to compress the telescopic spring 408, deforming it. Once the arc plate 407 is fully inserted into the movable groove 406, the return spring 412 releases its elastic potential energy, pushing the push plate 411 upward inside the slot 404. This push plate 411 then pushes the insert plate 405 outward, disengaging the arc plate 407 from the slot 410. Finally, pull the pull plate 402 to pull the insert plate 405 out of the slot 404, thus removing the filter plate 403.

[0045] 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.
