Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing, and in particular to a rolling mill for processing metal products. Background Technology

[0002] The Industrial Revolution of the 18th and 19th centuries spurred the rapid development of machinery manufacturing, construction, and transportation tools such as trains and ships. These fields saw a dramatic increase in demand for standardized metal sheets. At that time, the production of metal sheets mainly relied on manual forging, which not only consumed a lot of manpower but also had extremely low production efficiency. Moreover, the forged sheets had uneven thickness and poor surface flatness, failing to meet the basic requirements of material specifications and quality for large-scale industrial production. As a result, a rolling mill for metal product processing came into being.

[0003] The core of a rolling mill for metal product processing is to utilize the plastic deformation of metal to form a billet by applying pressure through rollers. Its key components are paired rollers with an adjustable roll gap between them. When the metal billet enters the roll gap, the rollers apply pressure, causing the billet stress to exceed the yield limit, resulting in permanent plastic deformation, thickness compression, and length and width extension. The thickness is controlled according to the preset roll gap. At the same time, the rotation of the rollers drives the continuous transport of the billet, which needs to be gradually thinned through multiple rolling passes. In addition, auxiliary systems such as roll gap adjustment, temperature control, and tension control are provided to ensure forming accuracy and stability, and finally output sheet or strip that meets the requirements.

[0004] Currently, rolling mills for metal product processing have become core equipment for metal billet processing due to their efficient continuous rolling capability and stable forming accuracy. They significantly improve the production efficiency of sheet and strip materials, and can also optimize the internal structure of metals through rolling to improve the mechanical properties of finished products. They play a significant role in promoting the large-scale development of the metal processing industry. However, the existing equipment has relatively limited finished product specifications, and the rolling mill roll system parameters and rolling program are fixed, mainly suitable for products of specific widths. This results in a significant reduction in its adaptability to the production of multiple varieties. Therefore, a rolling mill for metal product processing is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rolling mill for metal product processing, which aims to improve the problem that the existing equipment has a relatively limited range of finished product specifications, resulting in a significant reduction in its adaptability to the production of multiple varieties.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rolling mill for processing metal products includes a housing, a feeding plate fixedly connected to the inner wall of the housing, a cutting mechanism fixedly connected to one side of the housing, an outer shell fixedly connected to one side of the housing, and a discharge mechanism fixedly connected to the inner wall of the outer shell.

[0008] The cutting mechanism includes a support plate, an outer plate fixedly connected to one side of the support plate, a motor fixedly connected to the inner wall of the support plate, two push plates fixedly connected to the drive end of the motor, a pull plate rotatably connected to the side of the push plate away from the motor, a connecting column rotatably connected to the other side of the pull plate, a fixing plate fixedly connected to the outer wall of the connecting column, a cutting blade fixedly connected to one side of the fixing plate, and a limit assembly fixedly connected to one side of each of the two fixing plates.

[0009] As a further description of the above technical solution:

[0010] The unloading mechanism includes two motors, the outer walls of which are fixedly connected to the inner wall of the housing. A transmission assembly is fixedly connected to the drive end of each motor. Multiple protrusions are fixedly connected to one side of the transmission assembly. Multiple limiting plates are fixedly connected to the inner wall of the housing. Multiple support columns are slidably connected to the inner wall of the housing. Multiple grooves are formed on the inner wall of each support column. Rollers are rotatably connected to the inner wall of each support column. A rotating plate is rotatably connected to one side of the housing. Screws are threaded onto the inner wall of the rotating plate.

[0011] As a further description of the above technical solution:

[0012] The limiting component includes two limiting blocks, one side of each of the two limiting blocks is fixedly connected to one side of the fixed plate, the inner wall of the outer plate is provided with four limiting grooves, and the inner wall of the outer plate is provided with two through holes.

[0013] As a further description of the above technical solution:

[0014] The transmission assembly includes two drive wheels. One side of the drive wheel is fixedly connected to the drive end of the second motor, and two driven wheels are rotatably connected to one side of the housing. The drive wheels and the driven wheels are coupled together by a belt.

[0015] As a further description of the above technical solution:

[0016] The outer wall of the protrusion is slidably connected to the inner wall of the roll, and the inner wall of the groove is slidably connected to the outer wall of the limiting plate, wherein one side of each of the four support columns is in contact with one side of the rotating plate.

[0017] As a further description of the above technical solution:

[0018] The outer walls of both drive wheels are rotatably connected to the inner wall of the housing, and the outer wall of the screw is threadedly connected to the inner wall of the housing;

[0019] As a further description of the above technical solution:

[0020] The outer wall of the limiting block is slidably connected to the inner wall of the limiting groove, and the outer wall of the connecting column is slidably connected to the inner wall of the limiting assembly.

[0021] As a further description of the above technical solution:

[0022] The outer wall of the motor is rotatably connected to the inner wall of the outer plate, one side of each of the two pull plates is slidably connected to one side of the support plate, and one side of each of the two push plates is slidably connected to one side of the outer plate.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, by starting the motor on the inner wall of the support plate, its driving force drives the two push plates to rotate, and the pull plate moves accordingly. With the cooperation of the limiting groove and the limiting block, as well as the limiting of the connecting column by the through hole, the two fixed plates can be attached to one side of the outer plate to make opening and closing movements, thereby driving the cutting blade to attach to the surface of the blanking plate to complete the opening and closing action. This linkage structure allows the calender to adjust the finished product specifications by opening and closing the cutting blade when processing the blank, solving the problem of the single finished product specifications of traditional equipment and greatly improving the production adaptability of the calender.

[0025] 2. In this utility model, two motors on the inner wall of the outer casing are started. The two motors output reverse driving force to drive the drive wheel to rotate. Under belt transmission, the driven wheel rotates synchronously with the drive wheel, and the protrusion causes the roll to rotate accordingly, ensuring rolling stability. When maintenance is required, the screw is turned to release the restriction of the casing on the rotating plate. After the rotating plate rotates along the outer wall of the casing, it no longer limits the support column. The support column can then slide out of the casing with the roll for maintenance. After maintenance, the support column and roll can be quickly reset and installed with the help of the groove and the limiting plate, which greatly improves the maintenance efficiency of the calender.

[0032] 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.

[0033] Reference Figures 1 to 3 The present invention provides an embodiment of a rolling mill for processing metal products, comprising a housing 1, which serves as the main frame of the rolling mill, providing installation space and support for all components, ensuring the overall structural stability of the rolling mill during operation, and serving as the basic carrier for rolling metal products. A feeding plate 2 is fixedly connected to the inner wall of the housing 1, which is used to transport the finished products. A cutting mechanism 3 is fixedly connected to one side of the housing 1 to precisely cut the metal billet, meeting the processing requirements of finished products of different specifications. An outer shell 4 is fixedly connected to one side of the housing 1, and a drive-off mechanism 5 is fixedly connected to the inner wall of the outer shell 4.

[0034] The cutting mechanism 3 includes a support plate 31, which provides support. An outer plate 32 is fixedly connected to one side of the support plate 31, and a motor 33 is fixedly connected to the inner wall of the support plate 31. The motor 33 provides power to the cutting mechanism 3. The support plate 31 supports the motor 33 and the outer plate 32, providing a stable mounting base for the cutting mechanism 3 and ensuring that the structure does not shake during cutting operations. Two push plates 34 are fixedly connected to the drive end of the motor 33. The push plates 34 rotate under the drive of the motor 33, forming the first link in the power transmission. A pull plate 35 is rotatably connected to the side of the push plate 34 away from the motor 33. On the other side, a connecting column 36 is rotatably connected. The pull plate 35 converts the rotation of the push plate 34 into the linear motion of the connecting column 36, realizing the conversion of the power transmission form. A fixing plate 37 is fixedly connected to the outer wall of the connecting column 36. A cutting blade 38 is fixedly connected to one side of the fixing plate 37. The cutting blade 38 performs opening and closing movements under the drive of the fixing plate 37 to cut the metal blank on the blanking plate 2 to obtain the blank of the required size. A limit component 39 is fixedly connected to one side of both fixing plates 37. The limit component 39 restricts the movement direction of the fixing plate 37 to ensure that the cutting blade 38 can open and close smoothly along a straight line and ensure accurate cutting dimensions.

[0035] The unloading mechanism 5 includes two motors 51, the outer walls of which are fixedly connected to the inner wall of the outer casing 4. The two motors 51 provide power in opposite directions to achieve the rolling process of the metal billet. A transmission assembly 52 is fixedly connected to the drive end of each motor 51, transmitting the power from the motors 51. This transmission assembly 52 is a key structure for power transmission. Multiple protrusions 56 are fixedly connected to one side of the transmission assembly 52. ​​Multiple limiting plates 58 are fixedly connected to the inner wall of the casing 1. Multiple support columns 53 are slidably connected to the inner wall of the casing 1. The presence of the support columns 53 facilitates maintenance. Multiple grooves 5 are formed on the inner wall of each support column 53. 4. The groove 54 cooperates with the limiting plate 58 to restrict the movement direction of the support column 53, so that the support column 53 moves in a straight line during installation and disassembly without deviation. The inner wall of the support column 53 is rotatably connected to the roller 55. The roller 55 rotates under the drive of the transmission component 52. The metal billet is squeezed and extended by the reverse rotation of multiple rollers 55 to realize the rolling process. A rotating plate 57 is rotatably connected to one side of the housing 1. The inner wall of the rotating plate 57 is threaded with screws 59. The screws 59 fix the rotating plate 57 to the housing 1 to ensure that the rotating plate 57 firmly limits the support column 53. The fixation can be released by unscrewing the screws 59 during disassembly.

[0036] Reference Figures 2 to 4The limiting component 39 includes two limiting blocks 391. The inner wall of the outer plate 32 has four limiting grooves 392. One side of each limiting block 391 is fixedly connected to one side of the fixing plate 37. The limiting blocks 391 move with the fixing plate 37 and slide within the limiting grooves 392, restricting the movement direction of the fixing plate 37 and ensuring smooth opening and closing of the cutting blade 38. The inner wall of the outer plate 32 has two through holes 393, which provide a sliding channel for the connecting post 36 and simultaneously restrict the movement direction of the connecting post 36, allowing the connecting post 36 to drive the fixing plate 37. The plate 37 moves smoothly to prevent the cutting disc 38 from shaking. The transmission assembly 52 includes two drive wheels 521. One side of the drive wheel 521 is fixedly connected to the drive end of the second motor 51. The drive wheel 521 rotates under the drive of the second motor 51 and is the starting component of the transmission. Two driven wheels 522 are rotatably connected to one side of the housing 1. The drive wheel 521 and the driven wheel 522 are coupled together by a belt 523. The belt 523 transmits the rotation of the drive wheel 521 to the driven wheel 522, so that the two rotate synchronously and ensure that the rotation of the roller 55 is coordinated.

[0037] The outer wall of the protrusion 56 is slidably connected to the inner wall of the roll 55. The protrusion 56 is embedded in the roll 55, transmitting the rotational power of the transmission assembly 52 to the roll 55, causing the roll 55 to rotate synchronously with the transmission assembly 52 to achieve the rolling operation. The inner wall of the groove 54 is slidably connected to the outer wall of the limiting plate 58. The cooperation between the groove 54 and the limiting plate 58 provides guidance for the support column 53, allowing the support column 53 to be quickly aligned during installation and smoothly slide out during disassembly. One side of each of the four support columns 53 is in contact with one side of the rotating plate 57. The rotating plate 57 connects with the support column 53 via the rotation plate 57. The support column 53 is in contact with the roller 55 to limit its movement and prevent it from sliding during the operation of the roller 55, thus ensuring the stability of the rolling process. The outer walls of the two drive wheels 521 are rotatably connected to the inner wall of the housing 1. The housing 1 provides rotational support for the drive wheels 521, ensuring that the drive wheels 521 rotate stably and do not wobble, thus ensuring reliable transmission. The outer wall of the screw 59 is threadedly connected to the inner wall of the housing 1. The screw 59 is fixed to the housing 1 through the thread, thus firmly fixing the rotating plate 57 to the housing 1, ensuring that the rotating plate 57 firmly limits the support column 53 and prevents it from loosening.

[0038] The outer wall of the limiting block 391 is slidably connected to the inner wall of the limiting groove 392. The limiting block 391 slides within the limiting groove 392 and is fixedly connected to the fixing plate 37, driving the fixing plate 37 to move along the direction of the limiting groove 392, ensuring the smooth movement of the cutting disc 38. The outer wall of the connecting column 36 is slidably connected to the inner wall of the limiting assembly 39. The limiting assembly 39 restricts the movement of the connecting column 36, causing the connecting column 36 to drive the fixing plate 37 to move in a straight line, ensuring the accurate position of the cutting disc 38 when it opens and closes. The outer wall of the motor 33 is rotatably connected to the inner wall of the outer plate 32. The outer plate 32 is the inner wall of the motor 33. 3. Provides support to ensure the stability of motor 33 during operation and prevents vibration from affecting power output. One side of each of the two pull plates 35 is slidably connected to one side of the support plate 31. The support plate 31 provides sliding support for the pull plates 35, enabling the pull plates 35 to smoothly drive the connecting column 36, ensuring stable power transmission and coordinated movement of the cutting blade 38. One side of each of the two push plates 34 is slidably connected to one side of the outer plate 32. The outer plate 32 provides sliding support for the push plates 34, limiting the range of motion of the push plates 34, enabling the push plates 34 to stably drive the pull plates 35, and ensuring reliable opening and closing of the cutting blade 38.

[0039] Working principle: The motor 33 located on the inner wall of the support plate 31 is started, and the driving force of the motor 33 drives the two push plates 34 to rotate. This causes the pull plate 35 to move with the rotation of the push plates 34. Thanks to the cooperation of the limiting groove 392 and the limiting block 391 and the limiting of the connecting column 36 by the through hole 393, the two fixed plates 37 are in contact with one side of the outer plate 32 and open and close. This causes the two cutting blades 38 to be in contact with the surface of the blanking plate 2 and open and close. This allows the finished product specifications produced by the calender to be adjusted when processing the blank, thus greatly improving the production adaptability of the calender.

[0040] Two motors 51 located on the inner wall of the outer casing 4 are activated, with the driving forces of the two motors 51 acting in opposite directions. This causes the drive wheel 521 to rotate under the driving force of the motors 51. Thanks to the presence of the belt 523, the driven wheel 522 rotates synchronously with the rotation of the drive wheel 521. Thanks to the presence of the protrusion 56, multiple rollers 55 can rotate along with the rotation of the drive wheel 521 and the driven wheel 522. When maintenance of the entire calender is required, the screw 59 is turned, which releases the restriction of the rotating plate 57 on the outer wall of the outer casing 1, allowing the rotating plate 57 to rotate on the outer wall of the outer casing 1. This releases the restriction of the support column 53 on the rotating plate 57, allowing the support column 53, along with the rollers 55, to slide out from the inner wall of the outer casing 1 for maintenance. When the calender needs to be installed after maintenance, the cooperation of the groove 54 and the limiting plate 58 makes the installation of the support column 53 with the rollers 55 faster and more convenient, greatly improving the maintenance efficiency of the entire calender.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
