Description

Technical Field

[0001] This utility model relates to the field of steel rolling equipment technology, specifically to a direct-pressing twenty-roll rolling mill. Background Technology

[0002] The 20-roll mill, as a high-precision cold rolling equipment, is widely used in the production of high-end metal materials such as stainless steel, precision alloys, and electronic foil. Its core objective is to achieve high-precision, high-surface-quality rolling of extremely thin metal sheets. In existing 20-roll mill structures, eccentric sleeves or wedge mechanisms are typically used to adjust the rolling force and control the roll gap. These structures change the relative position of the rolls by rotating the eccentric sleeve or moving the wedge, thereby adjusting the roll gap. However, this traditional roll gap method suffers from problems such as complex structure, numerous transmission links, slow response speed, and high maintenance costs.

[0003] Chinese Patent Publication No. CN219169206U discloses a direct-pressing 20-roll rolling mill, including a machine housing. A guide adjustment frame is provided on one side of the machine housing, and a drive assembly is installed inside the guide adjustment frame. The drive assembly includes a drive screw and a drive threaded block installed inside the guide adjustment frame. This invention uses a pressing cylinder to drive a concave collar support plate and a linkage collar plate downwards, achieving multi-point limiting and uniform pressing. This solves the technical problem that the pressing structure of a 20-roll rolling mill cannot simultaneously meet the requirements of fast response speed, high rolling accuracy, and simple structure. Furthermore, the drive assembly allows for quick opening of the tilting support plate, facilitating access to the machine housing for maintenance operations without disassembling the housing.

[0004] However, in actual use, the aforementioned application, by using a downward-pressing cylinder to move the concave collar support plate and the linkage collar plate up and down, can only achieve the pressing adjustment of the ten rollers inside the machine casing, failing to simultaneously adjust the size of the metal strip inlet and outlet channels on both sides of the machine casing. Because the inlet and outlet sizes are fixed and cannot be dynamically adjusted according to changes in rolling specifications, it is difficult to form a matching transition channel between the inlet / outlet and the roll gap when rolling metal plates of different thicknesses. Therefore, this structure has poor adaptability to the production needs of multiple specifications and varying thicknesses, limiting the rolling range. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a shockproof high-voltage distribution cabinet to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A direct-pressing 20-roll rolling mill includes a lower protective shell. A transmission cylinder is installed on each side of the top of the lower protective shell. The output end of the transmission cylinder is connected to an upper protective shell. A transmission seat is installed inside both the upper and lower protective shells. A 10-roll shaft is rotatably mounted on one side of the transmission seat. An input port is opened on one side of both the lower and upper protective shells, and an output port is opened on the other side. A lifting and adjusting mechanism is provided inside both the input and output ports. An inspection port is opened on one side of both the lower and upper protective shells, and a maintenance protection mechanism is provided on one side of each inspection port.

[0008] Furthermore, in order to enable free adjustment of the size of the output and input ports on both sides of the upper and lower protective shells, the lifting adjustment mechanism includes a shrinkage groove on one side of the input and output ports. An adjustment plate is slidably installed inside the shrinkage groove. A support plate is connected to one end of the adjustment plate. A transmission screw is rotatably connected to the surface of the support plate. The transmission screw is threadedly connected to one side of the shrinkage groove.

[0009] Furthermore, in order to achieve the closure and protection of the inspection port, the inspection and protection mechanism includes a drive shaft rotatably connected to one side of the upper protective shell, an inspection door connected to the surface of the drive shaft, a driven door rotatably connected to one side of the lower protective shell, a limit bracket connected to the bottom of the inspection door, and the bottom of the limit bracket slidingly engaging with the top of the driven door.

[0010] Furthermore, in order to enable the inspection door and the driven door to rotate and open, a driven worm gear is connected to the top of the drive shaft, and a transmission worm is rotatably installed on the top of the upper protective shell. The transmission worm meshes with the driven worm gear, and a turning ring is connected to one end of the transmission worm.

[0011] Furthermore, to facilitate the turning and rotating of the transmission screw, a turning block is connected to one side of the transmission screw.

[0012] Furthermore, in order to control the extension and retraction of each cylinder, a multi-control switch is installed on one side of the surface of the upper protective shell.

[0013] Furthermore, in order to provide power for the rotation of the ten roller shaft, a bearing plate is connected to one side of the surface of both the lower and upper protective shells, and a drive motor is installed on the surface of the bearing plate.

[0014] Furthermore, in order to enable the device to move freely as a whole, casters are rotatably installed on each side of the bottom of the lower protective shell.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. Through the various transmission cylinders installed between the lower and upper protective shells, the upper protective shell and its internal ten rollers can be moved up and down, thereby changing the gap between the ten rollers in the two protective shells. This achieves direct and rapid pressing adjustment with fast response and high precision. During the adjustment process, the size of the input and output ports between the two protective shells is changed simultaneously. Furthermore, through the lifting adjustment mechanism, the size of the input and output ports can be adjusted individually according to the actual thickness of the metal sheet, significantly improving the rolling stability and adaptability of strips of different specifications and greatly expanding the process application range of the equipment.

[0017] 2. Through the maintenance and protection mechanism, after turning the transmission worm gear, the transmission shaft can drive the maintenance door and the driven door to rotate synchronously, which makes it convenient to open the maintenance port to inspect and replace the ten-roll shaft inside the upper and lower protective shells. Furthermore, through the self-locking property of the worm gear, the maintenance door and the driven door can be locked at the adjusted angle after opening, preventing them from rotating arbitrarily and improving the clearance efficiency and portability of the internal structure of the rolling mill.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] According to an embodiment of the present invention, a direct-pressing twenty-roll mill is provided.

[0029] like Figures 1-4 As shown, a direct-pressing 20-roll mill according to an embodiment of this utility model includes a lower protective shell 1 made of cemented carbide. Four transmission cylinders 2 are installed on each side of the top of the lower protective shell 1, evenly distributed at each corner of the top of the lower protective shell 1. The output end of the transmission cylinder 2 is connected to an upper protective shell 3. Transmission seats 4 are installed inside both the upper and lower protective shells 1. A ten-roll shaft 5 is rotatably mounted on one side of the transmission seat 4. By extending and retracting the transmission cylinders 2, the upper protective shell 3 and the ten-roll shaft 5 inside it can be moved up and down, thereby changing the gap between the ten-roll shafts 5 inside the two protective shells and achieving direct and rapid pressing adjustment. Section; The lower protective shell 1 and the upper protective shell 3 have an inlet 6 on one side and an outlet 7 on the other side. During the pressing and adjustment process, the size of the inlet 6 and the outlet 7 between the two protective shells can be changed simultaneously, so as to facilitate the passage of metal plates of different thicknesses; The inlet 6 and the outlet 7 are equipped with lifting adjustment mechanisms 8 inside, which are used to manually adjust the opening size of the inlet 6 and the outlet 7 individually; The lower protective shell 1 and the upper protective shell 3 each have an inspection port 9 on one side, which is used to facilitate the inspection and replacement of the ten roller shaft 5 inside the upper protective shell 3 and the lower protective shell 1. The inspection port 9 is equipped with an inspection and protection mechanism 10 on one side, which is used to freely control the opening and closing of the inspection port 9.

[0030] like Figures 1-6As shown, the lifting adjustment mechanism 8 includes a contraction groove 801 on one side of the input port 6 and the output port 7. An adjustment plate 802 is slidably installed inside the contraction groove 801. One end of the adjustment plate 802 is connected to a support plate 803. A transmission screw 804 is rotatably connected to the surface of the support plate 803. The transmission screw 804 is threadedly connected to one side of the contraction groove 801. By turning the transmission screw 804, it can drive the adjustment plate 802 to contract into the contraction groove 801 through the support plate 803, thereby changing the opening size of the input port 6 and the output port 7; maintenance and protection mechanism 10 The upper protective shell 3 includes a drive shaft 1001 rotatably connected to one side, with an inspection door 1002 connected to the surface of the drive shaft 1001. A driven door 1003 is rotatably connected to one side of the lower protective shell 1. A limit bracket 1004 is connected to the bottom of the inspection door 1002, and the bottom of the limit bracket 1004 slides against the top of the driven door 1003, allowing the driven door 1003 below to open or close synchronously when the inspection door 1002 is rotated open or closed. A driven worm gear 1005 is connected to the top of the drive shaft 1001. The top of the upper protective shell 3 rotates... A transmission worm gear 1006 is dynamically installed, which meshes with a driven worm wheel 1005. One end of the transmission worm gear 1006 is connected to a turning ring 1007. By rotating the turning ring 1007, the transmission worm gear 1006 drives the driven worm wheel 1005 and the transmission shaft 1001 to rotate, thereby causing the transmission shaft 1001 to drive the inspection door 1002 and the driven door 1003 to rotate. Furthermore, due to the self-locking property of the worm gear, after rotation adjustment, the inspection door 1002 and the driven door 1003 can be maintained at the adjusted angle, preventing them from... The transmission screw 804 can be rotated freely; a hexagonal prism-shaped turning block 11 is connected to one side of the transmission screw 804 to facilitate the turning and rotation of the transmission screw 804; a multi-control switch 12 is installed on one side of the surface of the upper protective shell 3 to control the extension and retraction of each transmission cylinder 2; a bearing plate 13 is connected to one side of the surface of both the lower protective shell 1 and the upper protective shell 3, and a transmission motor 14 is installed on the surface of the bearing plate 13 to provide power for the rotation of the ten roller shaft 5 inside the transmission seat 4; universal wheels 15 are rotatably installed on each side of the bottom of the lower protective shell 1 to facilitate the overall movement and adjustment of the device.

[0031] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0032] In practical use, depending on the thickness of the metal sheet to be rolled, the operator can control four transmission cylinders 2, evenly distributed at the top corner of the lower protective shell 1, to synchronously extend and retract according to the multi-control switch 12. The output end of the transmission cylinder 2 is connected to the upper protective shell 3, and its extension and retraction directly drives the upper protective shell 3 and its internal ten-roll shaft 5 to move up and down as a whole, realizing direct and rapid adjustment of the roll gap between the upper and lower protective shells 1. The force transmission path is simple and efficient, with rapid response and high control precision. During this adjustment process, as the position of the upper protective shell 3 relative to the lower protective shell 1 changes, the distance between the reserved input port 6 and output port 7 also changes synchronously, thereby automatically adapting to the channel height required for the current rolling, ensuring that the metal sheet can smoothly enter and exit the rolling area. To further accurately match the guiding requirements of strips of different thicknesses, the opening size of the input port 6 and output port 7 can also be finely adjusted by manually adjusting the lifting adjustment mechanism 8. In specific operation, the hexagonal prism-shaped turning block 11 at one end of the rotating transmission screw 804 causes the transmission screw 804 to rotate within the shrinkage groove 801, driving the support plate 803 and the adjusting plate 802 connected to it to slide along the shrinkage groove 801. When the adjusting plate 802 shrinks into the shrinkage groove 801, the effective opening size of the input port 6 or output port 7 increases; conversely, it decreases, thereby achieving independent and precise adjustment of the inlet and outlet sizes, effectively preventing the strip from scraping or shaking during the rolling process. When it is necessary to inspect or replace the internal ten-roll shaft 5, the turning ring 1007 at one end of the transmission worm 1006 can be rotated. Through the meshing transmission between the worm and the driven worm wheel 1005 at the top of the transmission shaft 1001, the transmission shaft 1001 is driven to rotate, thereby driving the inspection door 1002 on the upper protective shell 3 to open. Because the limit bracket 1004 at the bottom of the inspection door 1002 slides in conjunction with the top of the driven door 1003 on the lower protective shell 1, the rotation of the inspection door 1002 will synchronously drive the driven door 1003 to open together, realizing the simultaneous opening of the inspection port 9 on the upper and lower protective shells 1, which greatly facilitates the maintenance work of the internal transmission seat 4 and the ten roller shaft 5.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
