Description

Technical Field

[0001] The utility model relates to the technical field of multi-roller rolling mill steel coil position centering, in particular to a multi-roller rolling mill steel coil position centering calibration device. Background Art

[0002] In the production of steel products, steel coil is a common intermediate form of steel. Steel coil is usually processed into long strips through a continuous hot rolling process, and then rolled into a cylindrical roll for further processing.

[0003] At present, the centering of steel coils in multi-roll mills, especially those in twenty-roll mills, is generally performed by manual measurement before coil centering. The centering process is greatly affected by the shape of the steel coil. If the steel coil is not in the center position during the rolling process, it will have a great impact on the shape of the plate after rolling, and may even cause strip breakage.

[0004] Because the steel coils to be inspected are deep, manual measurement is difficult and accuracy is difficult to guarantee. Using laser measurement would not only increase the cost of the equipment, but the harsh working environment at the rolling site would easily interfere with the equipment's measurement, affecting accuracy. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the utility model provides a multi-roll mill steel coil position alignment verification device, which can effectively check the centering position of the steel coil of the multi-roll mill. It is easy to use, the measurement method is intuitive and accurate, and ensures that the plate shape after rolling is good.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A device for calibrating the position of a steel coil of a multi-roll rolling mill comprises a housing, a slide rod, a guide sleeve, a spring and a traction mechanism; the guide sleeve is fixedly connected to the housing, and the slide rod is sleeved in the guide sleeve; one end of the slide rod is connected to the traction mechanism, and the traction mechanism drives the slide rod to slide along the guide sleeve; the other end of the slide rod is provided with a boss, and the outer surface of the boss is provided with a mark; the spring is sleeved on the slide rod, with one end abutting against the end face of the guide sleeve and the other end abutting against the end face of the boss.

[0008] Furthermore, the shell is a rectangular shell, and a partition is provided inside the shell; the guide sleeve is provided with an external thread, and the guide sleeve is fixed to the partition by a nut.

[0009] Furthermore, the mark is a zone mark, which is divided into a first color zone and a second color zone. When the first color zone of the slide bar extends out of the housing, it indicates that the centering is correct. When only the second color zone of the slide bar extends out of the housing, it indicates that the centering is incorrect.

[0010] Furthermore, the first color area is a green area, and the second color area is a red area; when the green area of the slide bar extends out of the housing, it indicates that the centering is correct; when only the red area of the slide bar extends out of the housing, it indicates that the centering is incorrect.

[0011] Furthermore, the traction mechanism includes a handle, a tube rod and a pull rope; one end of the tube rod is fixed to the shell, the handle is installed on the other end of the tube rod, one end of the pull rope is connected to the trigger of the handle, and the other end of the pull rope is connected to the slide rod; pulling the trigger of the handle drives the slide rod to slide along the guide sleeve.

[0012] Furthermore, the pipe rod and the shell are detachably connected.

[0013] Furthermore, it also includes a guide column, which is fixed in the shell and the pull rope is passed around the guide column.

[0014] Furthermore, a groove is provided on the side wall of the guide column.

[0015] Compared with the prior art, the present invention has at least the following technical effects or advantages:

[0016] 1. The present invention verifies the distance between the push plate and the end face of the steel coil. A traction mechanism drives the slide bar to slide along the guide sleeve, allowing the slide bar to retract into the housing, thereby allowing the present invention to be placed between the push plate and the end face of the steel coil. Under the action of the spring force, the end face of the slide bar abuts against the end face of the steel coil, and the distance between the end face of the housing and the end face of the slide bar is equal to the distance between the push plate and the end face of the steel coil. The outer surface of the slide bar is marked, which can be used to intuitively and accurately verify the correct centering of the steel coil.

[0017] This new device effectively verifies the centering position of steel coils in a multi-roll mill. It is easy to use, offers intuitive and accurate measurement, and ensures the coil center is closest to the rolling centerline. This ensures accurate strip centering, reduces the chance of strip deviation during rolling, ensures a good finished strip shape, and improves the quality of the finished strip.

[0018] 2. The retraction action of the slide rod of the utility model is achieved by pulling the trigger of the handle to drive the slide rod to slide along the guide sleeve, and the extension and reset action is achieved by the spring to achieve the extension action, which is easy to use.

[0019] 3. The outer surface of the slide bar of this utility model is marked with a first color zone, green, and a second color zone, red. When the slide bar extends beyond the housing and the green zone is visible, alignment is correct; when the red zone is visible, alignment is incorrect. Using the red and green zones to distinguish between the two makes detection intuitive and accurate.

[0020] 4. The guide post of the utility model is fixed in the housing, and the side wall of the guide post is provided with a groove, and the pull rope passes through the groove of the guide post. The guide post plays a guiding role and ensures the smooth movement of the slide rod.

[0021] 5. The pipe rod and the shell of the utility model are detachably connected, which is convenient for installation and disassembly. After disassembly, it takes up little space and is convenient for storage and transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] [Example]

[0035] like Figure 1-5 As shown, a multi-roller rolling mill coil position centering calibration device includes a housing 1, a slide rod 2, a guide sleeve 3, a spring 4 and a traction mechanism 5.

[0036] The housing 1 is a long rectangular box structure, with a partition 11 provided in the middle of the box, and a guide sleeve mounting hole provided on the partition 11.

[0037] The guide sleeve 3 is a cylindrical structure with a protrusion 31 on the outer wall and an external thread on the right end outer wall. The guide sleeve 3 passes through the guide sleeve mounting hole and is fixed to the partition 11 by a nut 6. The partition 11 is located between the protrusion 31 and the nut 6. The protrusion 31 plays a role in positioning and limiting.

[0038] The slide rod 2 is a round rod, with the diameter of its right end corresponding to the inner diameter of the guide sleeve 3. A circular boss 21 is located on the left end of the slide rod. The left side of the outer surface of the circular boss 21 is marked with a red area 101, and the right side is marked with a green area 102. The left side of the housing 1 has a mounting hole corresponding to the circular boss 21 of the slide rod 2. The spring 4 is mounted on the slide rod 2, passing through the mounting hole and the guide sleeve 3. The spring 4 is positioned between the right end of the circular boss 21 and the left end of the guide sleeve 3.

[0039] When the green area 102 of the circular boss 21 of the slide bar 2 is exposed from the housing, it indicates that the centering is correct. Only when the red area 101 of the circular boss 21 of the slide bar 2 is exposed from the housing, it indicates that the centering is incorrect.

[0040] The traction mechanism 5 is similar to a trash clamp and includes a handle 51, a tube 52, and a pull rope 53. The front end of the tube 52 is threadedly connected to the rear side of the shell 1 and is located at the right end of the shell 1. The handle 51 is mounted on the rear end of the tube 52. One end of the pull rope 53 is connected to the trigger of the handle 51, and the other end of the pull rope 53 is connected to the right end of the slide 52. Pulling the trigger of the handle 51 causes the slide 2 to slide along the guide sleeve 3 and move to the right. The spring 4 is in a compressed state, and the slide 2 retracts into the shell 1. Release the trigger of the handle 51, and the slide 2 returns to its original position under the action of the elastic force of the spring 4, and the slide 2 extends out of the shell 1.

[0041] The rod 52 is detachably connected to the housing 1, making it easy to install and remove. After removal, it takes up little space and is convenient for storage and transportation. The slide bar 2 retracts by pulling the trigger of the handle 51, driving the slide bar to slide along the guide sleeve 3. The extension and reset action is achieved by extending the spring 4, making it easy to use.

[0042] Guide post 9 is vertically fixed to the bottom surface of housing 1, with its axis perpendicular to the axis of slide bar 2. A groove is centrally located on the outer wall of guide post 9, into which pull cord 53 is wound. Guide post 9 serves as a guide, ensuring smooth movement of slide bar 2.

[0043] The working principle and working process of this utility model are as follows:

[0044] During use, the handle 51 of the traction mechanism 5 is held by hand, and the trigger of the handle 51 is pulled to retract the slide rod 2 into the housing 1, thereby allowing the present invention to be placed between the push steel plate 8 and the end face of the steel coil 1, with the spring 4 in a compressed state. Release the trigger of the handle 51, and the slide rod 2 returns to its original position under the action of the elastic force of the spring 4. Under the action of the elastic force of the spring 4, the left end face of the slide rod 2 rests against the right end face of the steel coil 1. At this time, the distance between the right end face of the housing 1 and the left end face of the slide rod 2 is the distance between the end face of the core shaft and the end face of the steel coil 1. If the distance between the end face of the core shaft and the end face of the steel coil 1 is too large or too small, it indicates that the position of the steel coil 1 is not centered. The present invention provides a marking area on the outer surface of the circular boss 21 of the slide rod 2. When the green area 102 of the circular boss 21 of the slide rod 2 is exposed from the housing, it indicates that the centering is correct. Only when the red area 101 of the circular boss 21 of the slide rod 2 is exposed from the housing, it indicates that the centering is incorrect.

[0045] The utility model is easy to use. By distinguishing between the red area 101 and the green area 102, the detection is intuitive and accurate. It can effectively check the centering position of the steel coil of the multi-roll mill, so that the center of the steel coil is closest to the rolling center line. The centering accuracy of the steel strip is guaranteed, the probability of the steel strip running off during the rolling process is reduced, and the shape of the steel strip after rolling is ensured to be good, thereby improving the shape quality of the steel strip after rolling.

[0046] The protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent substitutions or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
