Description

Technical Field

[0001] This utility model relates to the field of stainless steel processing technology, and in particular to a stainless steel rolling eccentric stress buffer device. Background Technology

[0002] Stainless steel rolling is a processing technology that uses one or more pairs of rolling mills to rotate and extrude stainless steel billets, causing them to undergo plastic deformation and thus obtaining stainless steel plates, pipes, or profiles of the required shape and size. During the rolling process, factors such as the inhomogeneity of the stainless steel material itself, deviations in the installation accuracy of the rolling mills, and changes in the rolling speed can lead to uneven pressure distribution on the billet, resulting in eccentric stress. Eccentric stress not only affects the dimensional accuracy and surface quality of stainless steel products, but in severe cases, it can also cause accelerated wear of the rolling mills, equipment vibration, and even equipment failure. Therefore, eccentric stress buffering equipment is needed to alleviate this phenomenon.

[0003] Rolling bias stress buffer equipment is a device installed in the rolling mill system to absorb and disperse bias stress generated during the rolling process, ensuring the smooth operation of the rolling process. Traditional bias stress buffer equipment usually adopts a simple spring or rubber buffer structure, which buffers stress through the compression deformation of elastic elements.

[0004] The existing stainless steel rolling eccentric stress buffer device has the following shortcomings:

[0005] On the one hand, existing buffering equipment uses a single spring or rubber buffering structure, which has limited buffering effect. When the bias stress is too large, the elastic element is prone to over-compression or even failure, and cannot effectively buffer the stress, resulting in quality problems such as uneven thickness and surface wavy patterns in stainless steel plates during the rolling process. On the other hand, the connection between the buffering structure of traditional equipment and the rolling mill is relatively fixed, making it difficult to flexibly adjust according to stainless steel billets of different specifications and rolling processes. This results in poor equipment versatility and increases the equipment procurement and maintenance costs for enterprises. Utility Model Content

[0006] This invention proposes a stainless steel rolling bias stress buffer device, which achieves efficient stress absorption through a multi-stage buffer structure and improves the versatility of the device by combining an adjustable installation design, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a stainless steel rolling bias stress buffer device, comprising a fixed frame, a mounting plate, and a stress transmission plate. The mounting plate is disposed on the top of the fixed frame, and the stress transmission plate is disposed on the top of the mounting plate. An elastic buffer component is disposed at each of the four corners of the opposite surfaces of the fixed frame and the mounting plate. Adjustment components are fixedly connected to the left and right sides of the lower surface of the mounting plate. A set of horizontally symmetrical sliding components is disposed on the front and rear sides of the opposite surfaces of the mounting plate and the stress transmission plate. Three arc-shaped buffer plates are disposed sequentially from front to back on the top of the stress transmission plate.

[0008] Preferably, a fixing plate is fixedly connected to the bottom of the arc-shaped buffer plate, and a plurality of compression springs are fixedly connected to the upper surface of the fixing plate. The top of the compression springs is fixedly connected to the inner surface of the arc-shaped buffer plate. Fixing bolts are provided on both the left and right sides of the top of the fixing plate, and the fixing plate is fixedly installed on the top of the stress transmission plate by fixing bolts.

[0009] Preferably, the horizontal sliding assembly includes a sliding guide rod, with connecting blocks fixedly connected to both ends of the sliding guide rod. The connecting blocks are fixedly connected to the upper surface of the mounting plate. A sliding block is slidably connected to the outer surface of the sliding guide rod. The top of the sliding block is fixedly connected to the lower surface of the stress transmission plate. Two symmetrically arranged sliding blocks are fixedly connected to opposite sides with return springs. The return spring is sleeved on the outside of the sliding guide rod, and the end away from the sliding block is fixedly connected to the outer surface of the connecting block on the same side.

[0010] Preferably, the elastic buffer assembly includes an outer cylinder, which is fixedly connected to the upper surface of the fixing frame. An inner rod is slidably inserted into the top end of the inner surface of the outer cylinder. The top end of the inner rod is fixedly connected to the lower surface of the mounting plate. A helical spring is provided on the outer side of the outer cylinder and the inner rod. The bottom end of the helical spring is fixedly connected to the upper surface of the fixing frame, and the top end of the helical spring is fixedly connected to the lower surface of the mounting plate.

[0011] Preferably, the adjustment component includes a U-shaped connecting plate, with two U-shaped connecting plates fixedly connected to the left and right sides of the lower surface of the mounting plate, and an annular pressure plate provided on the lower surface of the inner wall of the U-shaped connecting plate.

[0012] Preferably, a knob is provided on the top of the annular pressure plate, and a transmission screw is fixedly connected to the bottom end of the knob. The transmission screw passes through the knob and extends to the bottom of the U-shaped connecting plate. A threaded cylinder is threadedly connected to the bottom end of the outer surface of the transmission screw, and the bottom end of the threaded cylinder is fixedly connected to the upper surface of the fixing frame.

[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0014] 1. In this utility model, efficient stress buffering is achieved through the cooperation of the elastic buffer component, the horizontal sliding component, and the arc-shaped buffer plate. When the stainless steel billet generates bias stress during the rolling process, the stress first acts on the arc-shaped buffer plate at the top of the stress transmission plate. The arc-shaped buffer plate is connected to the stress transmission plate through the compression spring on the bottom fixed plate. The compression spring can be compressed and deformed when subjected to force to absorb part of the stress. At the same time, the arc-shaped buffer plate itself will also undergo elastic deformation to further disperse the stress. If the stress causes the stress transmission plate to shift horizontally, the connecting slider in the horizontal sliding component will slide on the sliding guide rod. The return springs on both sides stretch or compress to generate reverse elastic force, adjusting the position of the stress transmission plate to make the stress distribution more uniform. The elastic buffer component between the fixed frame and the mounting plate has a spiral spring that is compressed when subjected to vertical stress, and the inner rod slides in the outer cylinder to absorb and buffer the vertical stress. The multi-level buffer structure works together, which can more effectively absorb and disperse bias stress compared with the traditional single buffer structure, avoiding quality problems such as uneven thickness and surface defects in stainless steel plates, and ensuring the rolling quality.

[0015] 2. In this utility model, the equipment is flexibly adjustable through the adjustment component, improving its versatility. When it is necessary to roll stainless steel billets of different specifications, the knob in the adjustment component is turned, which drives the transmission screw to rotate. Since the transmission screw is threadedly connected to the threaded cylinder, and the threaded cylinder is fixed on the fixed frame, the transmission screw will move up and down inside the threaded cylinder when it rotates, thereby driving the annular pressure plate and the U-shaped connecting plate to move up and down, realizing the adjustment of the mounting plate height. After the mounting plate height changes, the position of the stress transmission plate and the arc-shaped buffer plate also changes accordingly, enabling the equipment to adapt to billets of different thicknesses and rolling process requirements. This design changes the traditional fixed connection method of the equipment, eliminating the need to replace equipment parts, reducing the enterprise's equipment procurement and maintenance costs, and greatly improving the equipment's versatility and applicability.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a technical solution: it includes a fixing frame 1, a mounting plate 2, and a stress transmission plate 5. The mounting plate 2 is set on the top of the fixing frame 1, and the stress transmission plate 5 is set on the top of the mounting plate 2. An elastic buffer component 3 is set at each of the four corners of the opposite surfaces of the fixing frame 1 and the mounting plate 2. Adjustment components 4 are fixedly connected to the left and right sides of the lower surface of the mounting plate 2. A set of horizontally sliding components 6 with left and right symmetry are set on the front and rear sides of the opposite surfaces of the mounting plate 2 and the stress transmission plate 5. Three arc-shaped buffer plates 7 are set sequentially from front to back on the top of the stress transmission plate 5. A fixing plate 71 is fixedly connected to the bottom of the arc-shaped buffer plates 7. Several compression springs 72 are fixedly connected to the upper surface of the fixing plate 71. The top of the compression springs 72 is connected to the inner surface of the arc-shaped buffer plates 7. The surface is fixedly connected, and fixing bolts 73 are provided on both the left and right sides of the top of the fixing plate 71. The fixing plate 71 is fixedly installed on the top of the stress transmission plate 5 by fixing bolts 73. The horizontal sliding assembly 6 includes a sliding guide rod 61. Both the left and right ends of the sliding guide rod 61 are fixedly connected to connecting blocks 62. The connecting blocks 62 are fixedly connected to the upper surface of the mounting plate 2. The outer surface of the sliding guide rod 61 is slidably connected to the connecting slider 63. The top of the connecting slider 63 is fixedly connected to the lower surface of the stress transmission plate 5. The opposite sides of the two symmetrically arranged connecting sliders 63 are fixedly connected to the return springs 64. The return springs 64 are sleeved on the outside of the sliding guide rod 61 and the end away from the connecting slider 63 is fixedly connected to the outer surface of the connecting block 62 on the same side.

[0025] The overall effect of Embodiment 1 is as follows: Through three arc-shaped buffer plates 7 arranged sequentially from front to back, a large area can be in contact with the stainless steel billet. When the billet generates bias stress during the rolling process, the arc-shaped buffer plates 7 convert the stress into the elastic deformation of the compression springs 72 on the bottom fixed plate 71, absorbing part of the stress. At the same time, they also undergo elastic deformation to further disperse the stress. In the horizontal sliding assembly 6, the connecting slider 63 can slide freely on the sliding guide rod 61. When the stress transmission plate 5 is subjected to bias stress in the horizontal direction, the connecting slider 63 slides on the sliding guide rod 61, and the return springs 64 on both sides are stretched or compressed to generate a reverse elastic force, adjusting the position of the stress transmission plate 5, so that the stress distribution on the stress transmission plate 5 is more uniform, thereby effectively buffering the bias stress in the horizontal direction and avoiding quality problems of the stainless steel plate caused by stress concentration.

[0026] Example 2: Figure 4 and Figure 5 As shown, this utility model provides a technical solution: the elastic buffer assembly 3 includes an outer cylinder 31, which is fixedly connected to the upper surface of the fixing frame 1. An inner rod 32 is slidably inserted into the top end of the inner surface of the outer cylinder 31. The top end of the inner rod 32 is fixedly connected to the lower surface of the mounting plate 2. A helical spring 33 is provided on the outer side of the outer cylinder 31 and the inner rod 32. The bottom end of the helical spring 33 is fixedly connected to the upper surface of the fixing frame 1, and the top end of the helical spring 33 is fixedly connected to the lower surface of the mounting plate 2. The adjusting assembly 4 includes U Two U-shaped connecting plates 41 are fixedly connected to the lower surface of the mounting plate 2 on the left and right sides respectively. An annular pressure plate 42 is provided on the lower surface of the inner wall of the U-shaped connecting plate 41. A knob 43 is provided on the top of the annular pressure plate 42. A transmission screw 44 is fixedly connected to the bottom end of the knob 43. The transmission screw 44 passes through the knob 43 and extends to the bottom of the U-shaped connecting plate 41. A threaded cylinder 45 is threadedly connected to the bottom end of the outer surface of the transmission screw 44. The bottom end of the threaded cylinder 45 is fixedly connected to the upper surface of the fixing frame 1.

[0027] The overall effect of embodiment 2 is as follows: In the elastic buffer assembly 3, when the fixed frame 1 and the mounting plate 2 are subjected to vertical bias stress, the helical spring 33 is compressed and deformed, and the inner rod 32 slides in the outer cylinder 31, converting the vertical stress into the elastic potential energy of the helical spring 33, absorbing and buffering the vertical bias stress, and ensuring the stability of the mounting plate 2 and the structure above it. The adjustment assembly 4 drives the transmission screw 44 to rotate by rotating the knob 43. Since the transmission screw 44 is threadedly connected to the threaded cylinder 45 and the threaded cylinder 45 is fixed on the fixed frame 1, the transmission screw 44 will move up and down in the threaded cylinder 45 when it rotates, thereby driving the annular pressure plate 42 and the U-shaped connecting plate 41 to move up and down, so as to realize the precise adjustment of the height of the mounting plate 2, so as to adapt to the rolling requirements of stainless steel billets of different specifications and improve the versatility of the equipment.

[0028] The working principle of the entire equipment is as follows: When installing the equipment, the height of the equipment is adjusted by adjusting component 4 according to the specifications of the stainless steel billet to be rolled. Rotating knob 43 drives transmission screw 44 to rotate and move up and down in threaded cylinder 45, thereby driving the annular pressure plate 42 and U-shaped connecting plate 41 to move up and down, thereby adjusting the height of mounting plate 2 and placing stress transmission plate 5 and arc-shaped buffer plate 7 in the appropriate position.

[0029] When the stainless steel billet enters the rolling process, it generates bias stress under the extrusion of the rolls. At this time, the arc-shaped buffer plate 7 at the top of the stress transmission plate 5 first contacts the billet, and the compression spring 72 at the bottom of the arc-shaped buffer plate 7 is compressed, converting part of the stress into its own elastic potential energy. At the same time, the arc-shaped buffer plate 7 itself undergoes elastic deformation, further dispersing the stress. If the stress transmission plate 5 is subjected to bias stress in the horizontal direction, the horizontal sliding component 6 starts to work, the connecting slider 63 slides on the sliding guide rod 61, and the return springs 64 on both sides stretch or compress to generate reverse elastic force, adjusting the position of the stress transmission plate 5 to make the stress distribution more uniform.

[0030] In the vertical direction, the elastic buffer assembly 3 between the fixed frame 1 and the mounting plate 2 plays a role. When subjected to vertical stress, the helical spring 33 is compressed, and the inner rod 32 slides in the outer cylinder 31 to absorb and buffer the vertical bias stress. The multi-level buffer structure works together to effectively absorb and disperse bias stress from the horizontal and vertical directions, ensuring that the stainless steel billet is subjected to uniform force during the rolling process and avoiding quality problems such as uneven thickness and surface defects. After the stress disappears, the reset spring 64 in the horizontal sliding assembly 6 returns to its original state and pulls the stress transmission plate 5 back to the initial position, preparing for the next rolling process.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
