Description

Technical Field

[0001] This invention relates to the field of roll cooling technology, and in particular to a water-cutting plate device with quick-change function and its usage method. Background Technology

[0002] In the metallurgical industry, rolling mills, guide rolls, or pinch roll devices on hot rolling production lines are often equipped with external cooling water for the rolls. For hot-rolled thin strip steel production, it is generally not permissible for cooling water to splash onto the strip surface to avoid affecting product performance. Therefore, existing technologies often install water-cutting devices between the mill stands, which, in conjunction with the rolls, guide the cooling water to flow down along both sides of the water-cutting device. In actual production, the water-cutting device is often pre-installed between the mill stands. If the thin strip on the production line experiences steel pile-up or breakage, the water-cutting device needs to be disassembled to obtain sufficient maintenance space. However, in high-temperature environments, complex disassembly is not feasible, making it impossible to quickly remove the water-cutting device.

[0003] In view of this, based on years of experience in production and design in this and related fields, the inventor has designed a water-cutting plate device with quick-change function and its usage method through repeated experiments, in order to solve the problems existing in the prior art. Summary of the Invention

[0004] The purpose of this invention is to provide a water-cutting plate device with quick-change function and its usage method, which can quickly and conveniently disassemble and assemble the water-cutting plate device as a whole, thereby improving work efficiency.

[0005] To achieve the above objectives, the present invention proposes a water-cutting plate device with quick-change function, installed between two pillars of a memorial archway, wherein the water-cutting plate device comprises:

[0006] A water-cutting plate, wherein each end of the water-cutting plate is provided with a rotating shaft that protrudes outward along the length direction of the water-cutting plate;

[0007] Two sliders are respectively sleeved on the two rotating shafts and rotate in cooperation with the rotating shafts. A locking block is fixed on the outside of the slider, and a locking hole is opened on the locking block.

[0008] Two fixed seats are respectively fixed to the inner walls of the two opposing columns. The slider is slidably engaged with the fixed seats. The fixed seats are provided with a retaining structure to limit the displacement of the slider.

[0009] Two pin locking mechanisms are respectively aligned and cooperate with the two locking blocks. Each pin locking mechanism includes at least a pin seat and a pin. The pin seat is fixed to the column and has an installation hole. The pin passes through the installation hole and the lock hole.

[0010] The present invention also proposes a method of using a water-cutting plate device with a quick-change function, wherein the water-cutting plate device is the water-cutting plate device as described above, and the method of use includes:

[0011] The pin is moved to insert into the lock hole, the slider is constrained by the pin and the enclosure structure, and the water-cutting plate is pressed against the surface of the roller to cut water.

[0012] Move the pin so that it is inserted into the lock hole and the earring, and move the water-cutting plate away from the roller to make room for roller replacement;

[0013] Move the pin to remove it from the lock hole and the earring, and pull the slider out of the fixing seat to complete the removal of the water-cutting plate.

[0014] Compared with the prior art, the present invention has the following features and advantages:

[0015] The present invention proposes a quick-change water-cutting plate device and its usage method. It employs a pin and retaining structure to constrain the slider's degree of freedom, thereby quickly fixing the slider to the fixed base, achieving rapid installation of the water-cutting plate. When disassembly is required, the pin is pulled out of the locking hole, allowing the slider to be pulled out of the fixed base for quick removal of the water-cutting plate. This quick-change water-cutting plate device has a simple structure, is easy to install and disassemble, requires no complex connection operations, and facilitates rapid replacement of the water-cutting plate and overall assembly / disassembly of the water-cutting plate device.

[0039] The details of the present invention can be more clearly understood by referring to the accompanying drawings and the description of specific embodiments. However, the specific embodiments of the present invention described herein are for illustrative purposes only and should not be construed as limiting the invention in any way. Under the teachings of this invention, those skilled in the art can conceive of any possible modifications based on the invention, and these should all be considered to fall within the scope of the invention.

[0040] like Figures 1 to 9As shown, this invention proposes a water-cutting plate device 100 with quick-change function, installed between two pillars 200 of an archway. The water-cutting plate device 100 includes a water-cutting plate 10, two sliders 20, two fixing seats 30, and two pin locking mechanisms 40. Each end of the water-cutting plate 10 is provided with a rotating shaft 11 protruding outward along its length. The two sliders 20 are respectively sleeved on the two rotating shafts 11 and rotatably engage with them. Locking blocks 21 are fixed to the outside of the sliders 20, and locking holes 22 are provided on the locking blocks 21. The fixed base 30 is fixedly connected to the inner wall of the two columns 200 respectively. The slider 20 is slidably engaged with the fixed base 30. The fixed base 30 is provided with a retaining structure 31 to limit the displacement of the slider 20. The two pin locking mechanisms 40 are respectively aligned and engaged with the two locking blocks 21. The pin locking mechanism 40 includes at least a pin seat 41 and a pin 42. The pin seat 41 is fixedly connected to the column 200 and has an installation hole. The pin 42 passes through the installation hole and the locking hole 22 so as to constrain the slider 20 and the water cutting plate 10 together between the two columns 200.

[0041] The quick-change water-cutting plate device 100 proposed in this invention uses a pin 42 and a retaining structure 31 to constrain the freedom of the slider 20, thereby quickly fixing the slider 20 to the fixing base 30, thus realizing the quick installation of the water-cutting plate 10. When disassembly is required, the pin 42 is pulled out from the locking hole 22, and the slider can be pulled out from the fixing base 30, thus realizing the quick disassembly of the water-cutting plate 10. This quick-change water-cutting plate device 100 has a simple structure, is easy to install and disassemble, requires no complicated connection operations, and facilitates the quick replacement of the water-cutting plate 10 and the overall assembly and disassembly of the water-cutting plate device 100.

[0042] In an optional embodiment of the present invention, the pin seat 41 is fixed to the outer side wall of the column 200, the mounting hole is parallel to the outer side wall and extends horizontally through the pin seat 41, the locking block 21 protrudes outward from the fixing seat 30, and the axis of the locking hole 22 is parallel to the axis of the mounting hole so that the pin 42 can be smoothly inserted into the locking hole 22. With the above structure, the insertion and removal of the pin 42 from the locking hole 22 can be achieved by moving the pin 42 along the axial direction of the mounting hole, which is convenient and quick.

[0043] In an optional embodiment, the pin locking mechanism 40 further includes a slot plate 43 and a stop lever 44. One end of the pin 42 facing away from the locking hole 22 protrudes from the pin seat 41 and forms a stop end. The stop lever 44 is perpendicular to the pin 42 and fixed to the stop end of the pin 42. The slot plate 43 and the locking block 21 are located on opposite sides of the pin seat 41. The slot plate 43 is horizontally positioned and fixed to the pin seat 41. At least one slot 45 for fixing the stop lever is provided on the slot plate 43. The stop lever 44 can be used as a handle for moving the pin 42, and through the cooperation of the stop lever 44 and the slot 45, it can also limit the movement of the pin 42 to ensure the positioning of the pin 42 on the slider 20.

[0044] In an alternative example, the shift lever 44 and the pin 42 are connected by threads, the pin 42 has a threaded hole, and one end of the shift lever 44 is screwed into the threaded hole.

[0045] In an optional example, the pin seat 41 is welded to the post 200.

[0046] In an optional example, the end of the cutting plate 10 is also provided with an ear ring 12. The pin 42 can pass through the mounting hole, the locking hole 22 and the ear ring 12 in sequence. Three slots 45 are sequentially spaced on the slot plate 43. The ear ring 12 limits the cutting plate 10 in the circumferential direction to prevent the cutting plate 10 from continuing to rotate around the rotating shaft 11. The position of the ear ring 12 is set to meet the constraint requirements of the cutting plate 10 when changing the roller. That is, after the pin 42 passes through the ear ring 12, the cutting plate 10 is placed away from the roller 300 to make room for the roller replacement. The three slots 45 on the slot plate 43 correspond to the three positions (stops) of the pin 42, and the different functions of the cutting plate 10 are realized by the three positions (stops) of the pin 42.

[0047] In an optional embodiment of the present invention, a wristband 23 for pulling the slider 20 is also fixed on the slider 20, and the slider 20 can be smoothly pulled out from the fixed seat 30 by means of the wristband 23.

[0048] In an optional embodiment of the present invention, the fixed base 30 includes at least a base plate 32, one surface of the base plate 32 is fixedly connected to the column 200, and the other surface of the base plate 32 is slidably engaged with the slider 20.

[0049] In an optional embodiment, the fixed base 30 further includes two limiting plates fixed to the base plate 32. The two limiting plates are arranged in a V-shape to form a enclosure structure 31. With the above structure, the V-shaped enclosure structure 31 can constrain the two planar degrees of freedom of the slider 20 on the base plate 32.

[0050] In one optional example of this embodiment, the column 200 has a threaded hole, the fixing seat 30 has a through hole, and a mounting bolt passes through the threaded hole and the through hole to fix the fixing seat 30 to the column 200.

[0051] In an optional example, the mounting base 30 is a welded steel structure.

[0052] In an optional embodiment of the present invention, the water-cutting plate 10 includes a swing frame 13, a counterweight 14, and a water-cutting plate body 15. The counterweight 14 and the water-cutting plate body 15 are respectively disposed on two opposite sides of the swing frame 13, and the rotating shaft 11 is mounted on the swing frame 13. With the above structure, the water-cutting plate 10 adopts a gravity arm pressing method to adaptively fit with the roller. The pressing force can be adjusted by adjusting the counterweight 14, which can ensure the water-blocking effect and reduce the wear of the water-cutting plate. Specifically, due to the rotational engagement between the rotating shaft 11 and the slider 20, after the slider 20 is fixed to the fixed seat 30, the water-cutting plate 10 will swing around the rotating shaft 11 under the action of the counterweight 14. The water-cutting plate body 15 is attached to the roller surface of the roll 300. When the cooling water is sprayed on the roller surface and flows down the roller surface, the cooling water will be blocked by the water-cutting plate body 15. On the one hand, the cooling water can cool the roller surface, and on the other hand, it also plays a cooling role on the swing frame 13, thus prolonging the thermal deformation and fatigue of the swing frame 13 under the baking of high temperature steel plate.

[0053] In one alternative example, the swing frame 13 has a triangular cross-section, the counterweight 14 is fixed to one side of the base of the triangle, and the water-cutting plate body 15 is fixed to one side of the apex of the triangle.

[0054] In an alternative example, a rotating shaft passes through and is fixedly connected to the swing frame 13, and both ends of the rotating shaft protrude from the swing frame 13 along the length direction of the water-cutting plate 10 and form a rotating shaft 11.

[0055] In an optional example, the slider 20 is provided with a bushing that corresponds to the shaft head of the rotating shaft 11 to ensure the rotational engagement between the slider 20 and the rotating shaft 11.

[0056] In an optional embodiment, the counterweight 14 comprises a plurality of stacked counterweight plates, each detachably connected to the swing frame 13. The counterweight of the water-cutting plate 10 can be adjusted by changing the number of counterweight plates.

[0057] In one optional example of this embodiment, the water-cutting plate body 15 is made of a polymer material, which has good wear resistance, corrosion resistance, and long service life.

[0058] In an optional example, the swing frame 13 is also provided with a handle 16 to facilitate the operator to rotate the water-cutting plate 10.

[0059] The present invention also proposes a method of using a water-cutting plate device with quick-change function, the method comprising:

[0060] The movable pin 42 is inserted into the lock hole 22, the slider 20 is constrained by the pin 42 and the enclosure structure 31, and the water-cutting plate 10 is pressed against the surface of the roller 300 to cut water.

[0061] Move the pin 42 so that it is inserted into the lock hole 22 and the ear ring 12, and move the water-cutting plate 10 away from the roller 300 to make room for the replacement of the roller.

[0062] Move the pin 42 out of the lock hole 22 and the earring 12, and pull the slider 20 out of the fixing seat 30 to complete the removal of the water-cutting plate 10.

[0063] The method of using the water-cutting plate device with quick-change function proposed in this invention can divide the water-cutting plate device into three states according to actual production needs, so as to meet the different operational requirements of water cutting, roller changing, and quick-change water-cutting plate, which greatly improves work efficiency.

[0064] Please refer to Figures 1 to 9 The present invention will now describe in detail, with reference to an embodiment, the water-cutting plate device 100 with quick-change function and its usage method.

[0065] like Figures 1 to 3 As shown, in this embodiment, the water-cutting plate device 100 includes a water-cutting plate 10, a slider 20, a fixed base 30, and a pin locking mechanism 40, wherein...

[0066] The water-cutting plate 10 includes a swing frame 13, a water-cutting plate body 15, and a counterweight 14. The swing frame 13 is a welded structural component with a rotating shaft in the middle. The front of the swing frame 13 is bolted to the water-cutting plate body 15, and the rear of the swing frame 13 is bolted to the counterweight 14. The water-cutting plate body 15 is made of high-polymer material, possessing high wear resistance and corrosion resistance. The counterweight 14 is a set of steel plates that can be added or removed according to pressure requirements to adjust the pressure of the front water-cutting plate body 15 pressing against the roller surface.

[0067] The fixed base 30 is a welded structure. The base plate 32 is connected to the column 200 of the pinch roller arch by mounting bolts. A limit plate (steel plate) is welded on the base plate 32 to form a V-shaped enclosure structure 31, which supports the slider 20. The slider 20 is a perforated steel block with a bushing 24 press-fitted inside the hole. A locking block 21 and a hand ring 23 are welded to the outer periphery of the slider 20. The locking block 21 has a locking hole 22 for use with the pin locking mechanism 40 to achieve the locking function. The hand ring 23 is used to assist in disassembly and assembly.

[0068] The pin locking mechanism 40 includes a pin seat 41, a pin 42, a slot plate 43, and a stop lever 44. After adjustment, the pin seat 41 is welded to the outer surface of the archway's column 200. The hole on the pin seat 41 guides the pin 42. The stop lever 44 is threaded to the pin 42, serving both as a holding element to push the pin 42 and, in conjunction with the slot plate 43 welded to the tail of the pin seat 42, to constrain the position of the pin 42 at different positions.

[0069] In this embodiment, the water-cutting plate device 100 is divided into three states according to its usage: the water-cutting plate 10 is in the working water-cutting state, the water-cutting plate 10 is in the roller changing state, and the water-cutting plate 10 is in the quick-change state. The above three states are realized by the cooperation of the pin 42 with the water-cutting plate 10 and the slider 20, which are described below:

[0070] 1. Working water-cutting state, such as Figure 4 , Figure 5 As shown. At this time, due to the action of the counterweight 14, the swing frame 13 will swing around its own axis 11. The water-cutting plate body 15 is in contact with the roller surface. When the cooling water is sprayed onto the roller surface and flows down the roller surface, the cooling water will be blocked by the water-cutting plate body 15. On the one hand, the cooling water can cool the roller surface, and on the other hand, it also plays a cooling role on the swing frame, prolonging the thermal deformation and fatigue of the swing frame 13 under the baking of high temperature steel plate. The locking hole 22 on the slider 20 is inserted by the pin 42, and the stop lever 44 is in position I. Through the combined action of the V-shaped enclosure structure 31 on the fixed seat 30 and the pin 42, the three planar degrees of freedom of the slider 20 are constrained.

[0071] 2. Roller changing status, such as Figure 6 , Figure 7 As shown. At this time, the handle 16 on the swing frame 13 is moved, causing the swing frame 13 to rotate around the axis. The stop lever 44 is moved, moving the pin 42 from position I to position II. As the pin 42 passes through the locking hole 22 on the slider 20, it is inserted into the ear ring 12 on the swing frame 13. At this time, the water-cutting plate 10 will be constrained, the swing frame 13 is now within the projection range of the archway column 200, the water-cutting plate body 15 will be in a low position (away from the roller 300), the roller changing space has been freed up, and the roller changing operation is not affected, so the roller can be moved and replaced along the axial direction.

[0072] 3. Quickly change status, such as Figure 8 , Figure 9 As shown. When encountering a stuck steel or needing to replace the water-cutting plate 10, the stop lever 44 can be swung out, and the pin 42 can be pulled until the stop lever 44 is in position III. By pulling the handle 23, the swing frame 13, along with the slider 20 and the bushing 24, can be pulled out of the fixed seat 30 for offline processing. After processing, it can be installed in reverse as described above (the quick-change state and the working water-cutting state are the opposite of each other).

[0073] The detailed explanations of the above embodiments are intended only to explain the present invention so as to facilitate a better understanding of the present invention. However, these descriptions should not be construed as limiting the present invention for any reason. In particular, the various features described in different embodiments can be arbitrarily combined with each other to form other embodiments. Unless there is an explicit description to the contrary, these features should be understood to be applicable to any embodiment, and not limited to the described embodiments.
