Technical Field
[0001] This utility model relates to the technical field of slab processing equipment, and in particular to an upper guide assembly for a vertical roll mill and the vertical roll mill itself. Background Technology
[0002] In existing vertical rolling mills, to facilitate the feeding of slabs from the feed channel, an upper guide assembly is typically rigidly connected to the upper vertical roll stand. The upper guide assembly itself is also rigidly connected. When the slab contacts the upper guide assembly, because the upper guide assembly lacks a buffer structure, the impact force between the slab and the upper guide assembly is directly transmitted to the upper vertical roll stand. This affects the normal operation of other parts of the vertical rolling mill, easily leading to damage and reducing its service life. Utility Model Content
[0003] The purpose of this utility model is to provide an upper guide assembly for a vertical roll mill and a vertical roll mill. The upper guide assembly has a buffer structure inside to prevent the impact force between the slab and the upper guide assembly from being directly transmitted to the upper vertical roll arch, which would affect the normal operation of the vertical roll mill and improve the service life of the vertical roll mill.
[0004] To achieve the above objectives, this utility model provides an upper guide assembly for a vertical rolling mill, including...
[0005] A guide plate, the top of which is fixedly connected to the archway on the vertical roller;
[0006] A buffer block is provided below the guide plate, and a gap is provided between the top of the buffer block and the bottom of the guide plate;
[0007] Multiple guide screws are provided. The buffer block has countersunk holes corresponding to the guide screws. The guide screws are located in the countersunk holes and their ends extend out of the countersunk holes and are threadedly connected to the guide plate.
[0008] Multiple elastic elements are disposed within the gap, and the number of elastic elements corresponds one-to-one with the number of guide screws. The elastic elements are sleeved on the outside of the guide screws, with one end of the elastic element abutting against the guide plate and the other end abutting against the buffer block. The elastic elements have a tendency to move the buffer block away from the guide plate.
[0009] Furthermore, the elastic element is a spring.
[0010] Furthermore, the bottom of the guide plate extends downward to provide a limiting boss, and the buffer block is provided with a stepped surface corresponding to the limiting boss.
[0011] Furthermore, the top of the guide plate is provided with a limiting step for positioning and installation with the archway on the vertical roller.
[0012] Furthermore, a weight-reducing groove is provided in the middle of the guide plate.
[0013] Furthermore, a limiting groove is coaxially formed at one end of the countersunk hole facing the guide plate, and one end of the elastic element is disposed in the limiting groove.
[0014] Furthermore, the bottom of the buffer block is provided with a downwardly convex guide arc surface.
[0015] Furthermore, the guide screw is a hexagonal countersunk screw.
[0016] This utility model also provides a vertical roll mill, including the upper guide assembly of the vertical roll mill as described in any of the above claims, and further including an upper vertical roll arch, a lower vertical roll arch, a first vertical roll device, a second vertical roll device, and guide rollers. The upper vertical roll arch and the lower vertical roll arch are arranged at intervals in the vertical direction.

Multiple guide screws are provided, and the buffer block has countersunk holes corresponding to the guide screws. The guide screws are located in the countersunk holes, and their ends extend outside the countersunk holes and are threadedly connected to the guide plate. Elastic elements are sleeved on the guide screws, and multiple elastic elements are located within the gap, with each elastic element corresponding to one guide screw. One end of each elastic element abuts against the guide plate, and the other end abuts against the buffer block.

[0028] like Figures 1 to 6As shown, a preferred embodiment of the present invention provides a guide assembly for a vertical roll mill, comprising a guide plate 1, a buffer block 2, multiple guide screws 4, and multiple elastic elements 5. The guide plate 1 serves as the mounting carrier, with its top fixedly connected to the upper archway 6 of the vertical roll. The buffer block 2 is located below the guide plate 1, with a gap 3 between its top and the bottom of the guide plate 1. During the slab rolling process, the bottom of the buffer block 2 contacts the slab, generating a certain impact force. To provide cushioning, the multiple elastic elements 5 are provided with... Within the gap 3, multiple guide screws 4 are provided to facilitate the restriction of the position of the elastic element 5. A countersunk hole 21 corresponding to the guide screws 4 is provided on the buffer block 2. The guide screws 4 are located in the countersunk hole 21, and their ends extend outside the countersunk hole 21 and are threadedly connected to the guide plate 1. The number of elastic elements 5 corresponds one-to-one with the number of guide screws 4. The elastic element 5 is sleeved on the outside of the guide screw 4, with one end of the elastic element 5 abutting against the guide plate 1 and the other end abutting against the buffer block 2. The elastic element 5 has a tendency to move the buffer block 2 away from the guide plate 1. When the slab contacts the bottom of the buffer block 2, multiple elastic elements 5 can be compressed simultaneously, thus forming a buffer and preventing the impact force from being directly transmitted to the vertical roll 6, which could affect the normal operation of the vertical roll mill and improve its service life.
[0029] In this embodiment, to facilitate the design of the elastic element 5 and simplify its structure, the elastic element 5 is a spring, which can be directly purchased. In some other embodiments, it can also be made of elastic materials such as rubber, TPU, TPV, etc. In some embodiments, to facilitate the disassembly and assembly of the guide screw 4, the guide screw 4 is a hexagonal countersunk screw, which is easy to disassemble and assemble.
[0030] Furthermore, in some embodiments, to avoid limiting the position of the buffer block 2 and the guide plate 1 during installation, see [reference needed]. Figure 3 A limiting boss 11 extends downward from the bottom of the guide plate 1, and a stepped surface 22 corresponding to the limiting boss 11 is provided on the buffer block 2. Similarly, to facilitate the installation and positioning of the guide plate 1 and the vertical roller upper archway 6, a limiting step 12 for installation and positioning with the vertical roller upper archway 6 is provided at the top of the guide plate 1, and the guide plate 1 and the vertical roller upper archway 6 are connected by screws. Further, to facilitate the limiting of the elastic element 5 during installation, see [reference needed]. Figure 4 A limiting groove 211 is coaxially formed at one end of the countersunk hole 21 facing the guide plate 1, and one end of the elastic member 5 is located in the limiting groove 211.
[0031] In some embodiments, to reduce the overall weight of the guide plate 1, a weight-reducing groove 13 is provided in the middle of the guide plate 1. Furthermore, to facilitate the feeding of the slab and reduce the friction between the slab and the buffer block 2, thereby increasing the feeding speed of the slab, a downwardly protruding guide arc surface 23 is provided at the bottom of the buffer block 2. The lowest point of the guide arc surface 23 contacts the slab, reducing the contact area between the buffer block 2 and the slab.
[0032] This utility model also provides a vertical roll mill, including the above-mentioned upper guide assembly, see reference. Figure 5 , Figure 6 It also includes an upper vertical roll archway 6, a lower vertical roll archway 7, a first vertical roll assembly 8, a second vertical roll assembly 9, and guide rollers 10. The upper vertical roll archway 6 and the lower vertical roll archway 7 are vertically spaced apart, with a mounting cavity a in the middle of each. The first vertical roll assembly 8 and the second vertical roll assembly 9 are located in mounting cavity a and spaced apart along its length. A feeding channel is provided between the first vertical roll assembly 8 and the second vertical roll assembly 9, with guide rollers 10 at both the inlet and outlet of the feeding channel. The operation of the first vertical roll assembly 8 and the second vertical roll assembly 9 drives the slab b to move and roll within the feeding channel. The upper guide assembly and the guide rollers 10 guide the slab b vertically.
[0033] In summary, this utility model embodiment provides an upper guide assembly for a vertical rolling mill and the vertical rolling mill itself. A buffer block 2 is provided below the guide plate 1, and a gap 3 is provided between the guide plate 1 and the buffer block 2. Multiple guide screws 4 are provided. The buffer block 2 has countersunk holes 21 corresponding to the guide screws 4. The guide screws 4 are located in the countersunk holes 21, with their ends extending outside the countersunk holes 21 and threadedly connected to the guide plate 1. Elastic elements 5 are sleeved on the guide screws, and multiple elastic elements 5 are located within the gap 3. The number of elastic elements 5 corresponds one-to-one with the number of guide screws 4. One end of the elastic element 5 abuts against the guide plate 1, and the other end abuts against the buffer block 2. The elastic element 5 has a tendency to move the buffer block 2 away from the guide plate 1. When the bottom of the buffer block 2 contacts the slab, the elastic element 5 can be compressed simultaneously to buffer the impact force between the slab and the buffer block 2, preventing the impact force from being directly transmitted to the upper vertical rolling mill and affecting its normal operation, thus improving the service life of the vertical rolling mill.
[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
