Description

Technical Field

[0001] The utility model relates to the technical field of bar production, in particular to a cooling water baffle for a bar rolling mill. Background Art

[0002] The rolling mill is the main production equipment of the bar production line. The heated billet is rolled between two rotating rollers. After multiple rolling passes, the rolled piece is deformed, shrunk, and extended, and finally becomes a finished bar product.

[0003] When operating, the rollers of a rolling mill must come into contact with hot workpieces reaching temperatures between 900°C and 1000°C. They must also apply a significant rolling force to the workpiece to complete the rolling process. This harsh working condition, where the rollers must press hard against the hot workpiece, significantly impacts the roller's service life due to its cooling conditions. To increase operating rates and production, steel mills generally employ a method of compressing the rolling cycle to the shortest possible time. This means the rollers spend the vast majority of their time working (passing steel), and the pure cooling time when not working (not passing steel, idling) is extremely short. To reduce roller wear and extend the amount of steel they can pass and their overall service life, steel mills generally employ forced water cooling with high water pressure and high water volume.

[0004] When high-pressure, high-volume cooling water is sprayed onto the rotating rolls, some of it inevitably bounces and splashes. If this splashing water reaches the head of the workpiece, it can cool it down and cause it to turn black, commonly known as "blackhead steel." This can lead to the workpiece not fitting into the mill pass or causing steel to pile up. Cooling water splashing outside the rolling channel also detracts from the aesthetics and cleanliness of the production environment. It can also make the floor slippery, creating a safety hazard. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a bar rolling mill cooling water baffle, which solves the problem of cooling water splashing in the rolling mill, can reduce the cooling water from splashing onto the inlet guide and rolled products, reduce the generation of "black steel", and reduce the probability of process failures.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A bar mill cooling water baffle, comprising a connecting rod and a plate body, wherein the middle portion of the connecting rod is connected to a surface of one end of the plate body, and both ends of the connecting rod are mounted on the hanging points of the worm gear box of the rolling mill, and the end of the plate body away from the connecting rod is located above the inlet guide of the rolling mill;

[0008] A guide groove is provided on a side of the plate body away from one end of the connecting rod, and the guide groove is located on a side of the plate body facing the rolling mill, and the opening of the guide groove faces the direction of the connecting rod.

[0009] Furthermore, mounting brackets are respectively provided on both sides of the plate body facing the rolling mill, one end of the mounting bracket is fixedly connected to the plate body, and the mounting bracket and the plate body form a slot with three sides open, and the mounting bracket is provided with a plurality of penetrating mounting holes;

[0010] The connecting rod includes a rod body, a connecting plate and a fixing screw. Two rod bodies are provided, and the two rod bodies are fixedly connected to the two ends of the connecting plate respectively. The connecting plate is provided with a threaded hole passing through the connecting plate. The connecting plate is slidably embedded in the slot, and the threaded hole can be aligned with any of the mounting holes. The fixing screw slides through the mounting hole and then is threadedly embedded in the threaded hole to fix the connecting plate in its current position in the slot.

[0011] Furthermore, the plate body is recessed with fixing grooves whose number is the same as the number of the mounting holes, and the fixing grooves are aligned with the mounting holes so that the fixing screws can be slidably embedded in the fixing grooves.

[0012] Furthermore, a locking mechanism is provided at each end of the connecting rod, and the locking mechanism includes a locking cylinder, a locking buckle and a locking screw. The locking cylinder is slidably sleeved outside the connecting rod, and one end of the locking buckle is fixedly connected to the locking cylinder, and the other end can be embedded between the hanging point and the worm gear box;

[0013] The locking screw is threadedly disposed in the locking cylinder and abuts against the connecting rod.

[0014] Furthermore, the locking buckle is an arc-shaped sheet structure.

[0015] The beneficial effects of the utility model are:

[0016] 1. By placing both ends of the connecting rod on the hanging points of the worm gear box of the rolling mill, and at the same time, the end of the plate away from the connecting rod passes through the gap between the rolling mill and the rolling mill beam, and is located above the inlet guide, the inlet guide is shielded. Under the action of the plate, the splashing cooling water is blocked, and the cooling water enters the guide groove along the plate and flows out through the two ends of the guide groove, reducing the cooling water from splashing onto the inlet guide and the rolled piece, reducing the possibility of cooling water splashing onto the head of the rolled piece to cause "black steel", reducing the probability of process failure, and at the same time reducing the splashing of cooling water, reducing safety hazards, and ensuring a clean and beautiful output environment.

[0017] 2. By inserting the connecting plate into the slot, aligning the threaded hole with the mounting hole at the appropriate height based on the distance between the inlet guide and the hanging point, the fixing screw is slid through the mounting hole and then threaded into the threaded hole, thereby fixing the connecting plate in its current position within the slot. This allows the end of the plate away from the connecting rod to be above the inlet guide, effectively shielding the cooling water. The connecting rod of this utility model can be adjusted in height on the plate to adapt to different rolling mill units, ensuring that the end of the plate away from the connecting rod is always above the inlet guide.

[0028] Example 1

[0029] Please also see Figure 1 and Figure 2 The cooling water baffle of the bar rolling mill in this embodiment includes a connecting rod 1 and a plate body 2.

[0030] The middle part of the connecting rod 1 is connected to one side of one end of the plate body 2, and both ends of the connecting rod 1 are placed on the hanging point 311 of the worm gear box 31 of the rolling mill 3. The end of the plate body 2 away from the connecting rod 1 is located above the inlet guide 32 of the rolling mill 3.

[0031] A guide groove 4 is provided on one side of the plate body 2 away from one end of the connecting rod 1 , and the guide groove 4 is located on the side of the plate body 2 facing the rolling mill 3 , and the opening of the guide groove 4 faces the direction of the connecting rod 1 .

[0032] The connecting rod 1 of this embodiment is threaded steel, and the connecting rod 1 and the guide groove 4 are connected to the plate body 2 by welding.

[0033] By placing both ends of the connecting rod 1 on the hanging point 311 of the worm gear box 31 of the rolling mill 3, and at the same time, the end of the plate 2 away from the connecting rod 1 passes through the gap between the rolling mill 3 and the rolling mill crossbeam 33, and is located above the inlet guide 32, the connecting rod 1 is suspended above the worm gear box 31 of the worm gear roll gap adjustment assembly of the rolling mill 3, thereby blocking the inlet guide 32.

[0034] Under the action of the plate body 2, the splashing cooling water is blocked, so that the cooling water enters the guide groove 4 along the plate body 2 and flows out through the two ends of the guide groove 4, reducing the cooling water from splashing onto the inlet guide and the rolled piece, reducing the possibility of cooling water splashing onto the head of the rolled piece to cause "black steel", reducing the probability of process failure, and at the same time reducing the splashing of cooling water, reducing safety hazards, and ensuring a clean and beautiful output environment.

[0035] When the roll needs to be replaced, the water baffle can be directly removed and then placed on the new rolling mill after the roll replacement is completed. During the roll replacement process, the installation and removal of the water baffle takes less time, does not delay the roll replacement time, and is convenient and quick.

[0036] Example 2

[0037] Please also see Figures 2 to 6 The cooling water baffle of the bar rolling mill in this embodiment includes a connecting rod 1 and a plate body 2.

[0038] The middle part of the connecting rod 1 is connected to one side of one end of the plate body 2, and both ends of the connecting rod 1 are placed on the hanging point 311 of the worm gear box 31 of the rolling mill 3. The end of the plate body 2 away from the connecting rod 1 is located above the inlet guide 32 of the rolling mill 3.

[0039] A guide groove 4 is provided on one side of the plate body 2 away from one end of the connecting rod 1 , and the guide groove 4 is located on the side of the plate body 2 facing the rolling mill 3 , and the opening of the guide groove 4 faces the direction of the connecting rod 1 .

[0040] like Figure 3 and Figure 6 As shown, in this embodiment, locking mechanisms are respectively provided at both ends of the connecting rod 1, and the locking mechanisms include a locking cylinder 5, a locking buckle 51 and a locking screw 52. The locking cylinder 5 is slidably sleeved on the outside of the connecting rod 1, and one end of the locking buckle 51 is fixedly connected to the locking cylinder 5, and the other end can be embedded between the hanging point 311 and the worm gear box 31.

[0041] The locking screw 52 is threadedly provided in the locking cylinder 5 and abuts against the connecting rod 1. In this embodiment, a connecting seat is fixedly provided on the outer wall of the locking cylinder 5, and the locking screw 52 is threadedly provided in the connecting seat and then penetrates into the locking cylinder 5.

[0042] By sliding the locking cylinder 5 onto the outside of the connecting rod 1 and then sliding the locking cylinder 5, the locking buckle 51 can be embedded between the hanging point 311 and the worm gear box 31. Under the fixing action of the locking screw 52, the locking cylinder 5 is fixed to the outside of the connecting rod 1, thereby fixing the connecting rod 1 on the hanging point 311, avoiding the displacement of the plate body 2 due to the vibration of the rolling mill 3, ensuring that the plate body 2 can be stably fixed on the worm gear box 31, and preventing the plate body 2 from falling and causing accidents.

[0043] The locking buckle 51 is an arc-shaped sheet structure. The arc shape of the locking buckle 51 can match the groove of the hanging point 311, so that the locking buckle 51 can be clamped between the hanging point 311 and the worm gear box 31.

[0044] The connecting rod 1 is fixed on the hanging point 311, and the end of the plate 2 away from the connecting rod 1 passes through the gap between the rolling mill 3 and the rolling mill beam 33, and is located above the inlet guide 32, so that the connecting rod 1 is suspended above the worm gear box 31 of the worm gear roll gap adjustment assembly of the rolling mill 3, thereby blocking the inlet guide 32.

[0045] Under the action of the plate body 2, the splashing cooling water is blocked, so that the cooling water enters the guide groove 4 along the plate body 2 and flows out through the two ends of the guide groove 4, reducing the cooling water from splashing onto the inlet guide and the rolled piece, reducing the possibility of cooling water splashing onto the head of the rolled piece to cause "black steel", reducing the probability of process failure, and at the same time reducing the splashing of cooling water, reducing safety hazards, and ensuring a clean and beautiful output environment.

[0046] like Figure 4 and Figure 5 As shown, mounting brackets 21 are provided on both sides of the plate body 2 facing the rolling mill 3. One end of the mounting bracket 21 is fixedly connected to the plate body 2, and the mounting bracket 21 and the plate body 2 form a slot 211 with three sides open. The mounting bracket 21 is provided with multiple penetrating mounting holes 212.

[0047] The connecting rod 1 includes a rod body 11, a connecting plate 12, and a fixing screw 13. Two rod bodies 11 are provided, and the two rod bodies 11 are fixedly connected to the ends of the connecting plate 12 respectively. The connecting plate 12 is provided with a threaded hole 121 extending therethrough. The connecting plate 12 slides into the slot 211, and the threaded hole 121 can be aligned with any mounting hole 212. The fixing screw 13 slides through the mounting hole 212 and then screws into the threaded hole 121, thereby fixing the connecting plate 12 in its current position in the slot 211. The locking cylinder 5 of this embodiment is slidably mounted on the outside of the rod body 11.

[0048] The connecting plate 12 is embedded in the slot 211, and according to the distance between the inlet guide 32 and the hanging point 211, the threaded hole 121 is aligned with the mounting hole 212 of an appropriate height, so that the fixing screw 13 slides through the mounting hole 212 and is threadedly embedded in the threaded hole 121, thereby fixing the connecting plate 12 at its current position in the slot 211, so that the end of the plate body 2 away from the connecting rod 1 can be above the inlet guide 32 to effectively block the cooling water.

[0049] Since the height positions of the lifting points 311 of different rolling mills are different, the connecting rod 1 of this embodiment can be adjusted to a height position on the plate body 2 to adapt to different rolling mill units, ensuring that the end of the plate body 2 away from the connecting rod 1 can be above the inlet guide 32.

[0050] like Figure 5 As shown, the plate body 2 is recessed with fixing slots 201, which are the same number as the mounting holes 212. The fixing slots 201 are aligned with the mounting holes 212, allowing the fixing screws 13 to slide into the fixing slots 201. The fixing slots 201 provide support points for the fixing screws 13, enhancing the stability of the connection between the connecting plate 12 and the plate body 2. In this embodiment, one end of the mounting bracket 21 is fixedly connected to the surface of the plate body 2 away from the guide groove 4, and one end of the slot 211 is open toward the guide groove 4. This ensures that if the fixing screws 13 accidentally fall off, the connecting plate 12 can be hung on the mounting bracket 21.

[0051] The usage process of the cooling water baffle of the bar rolling mill in this embodiment is as follows: according to the distance between the inlet guide 32 and the hanging point 311, the connecting plate 12 is embedded in the slot 211, and the threaded hole 121 is aligned with the mounting hole 212 of the appropriate height. The fixing screw 13 is slid through the mounting hole 212 and then threaded into the threaded hole 121, thereby fixing the connecting plate 12 at the current position in the slot 211.

[0052] Place both ends of the connecting rod 1 on the hanging point 311 of the worm gear box 31 of the rolling mill 3, so that the plate body 2 is located above the inlet guide 32 after passing through the gap between the rolling mill 3 and the rolling mill crossbeam 33 away from the end of the connecting rod 1; slide the locking cylinder 5, and the locking buckle 51 is inserted into the groove of the hanging point 311, and then tighten the locking screw 52, and the locking screw 52 is in contact with the rod body 11, so that the connecting rod 1 is fixed on the hanging point 311, and the cooling water can be blocked by the plate body 2.

[0053] When the roll needs to be replaced, loosen the locking screw 52 and slide the locking buckle 51 out of the groove of the hanging point 311, thereby separating the rod body 11 from the hanging point 311, so that the water baffle can be removed from the rolling mill 3, and then installed on the new rolling mill after the roll replacement is completed.
