Abstract
Description
Technical Field
[0001] This utility model relates to the field of baffle device technology, and in particular to a baffle device for a ring rolling machine. Background Technology
[0002] The baffle device of the ring rolling mill is an important component of the ring rolling mill. It is mainly used to support and lift the rings and work with other components of the ring rolling mill to complete the rolling process of the rings. Its structural design must meet the requirements of stability, wear resistance and coordinated operation with other devices. The design of the ring rolling mill baffle device must take into account strength, wear resistance, adjustability and coordination with the whole machine. Its core lies in achieving stable support and precise control during the ring rolling process through the integration of the main structure, positioning guide, lifting adjustment, cooling and lubrication devices.
[0003] An existing baffle device for a ring rolling machine (publication number: CN213002409U) has at least the following drawbacks: Although the prior art mentions that the upper panel is easy to replace, it does not take into account the daily maintenance of the entire baffle device, such as cleaning debris between the upper and lower panels and checking the tightness of the fixing structure. After long-term use, debris will affect the connection stability of the detachable structure, and the fixing structure is also prone to loosening due to vibration and other reasons. At the same time, in actual production, the ring rolling process may generate metal shavings flying, which may not only affect the safety of operators, but also damage other parts of the equipment. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a baffle device for a ring rolling machine.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A baffle device for a ring rolling machine includes a baffle body, which comprises a main mounting plate and a secondary mounting plate. A samarium cobalt magnet a and a silicon carbide ceramic heat insulation sleeve a are fixedly embedded in the side of the main mounting plate near the secondary mounting plate. One side of the silicon carbide ceramic heat insulation sleeve a is flush with the main mounting plate. A samarium cobalt magnet b and a silicon carbide ceramic heat insulation sleeve b are fixedly embedded in the side of the secondary mounting plate that is in contact with the main mounting plate. The silicon carbide ceramic heat insulation sleeve b is sleeved on the outside of the samarium cobalt magnet b and is flush with the surface of the secondary mounting plate. The main mounting plate and the secondary mounting plate are magnetically connected by the samarium cobalt magnet a and the samarium cobalt magnet b. The silicon carbide ceramic heat insulation sleeve a and the silicon carbide ceramic heat insulation sleeve b are in close contact with each other.
[0007] As a further embodiment of this utility model, a silicon nitride ceramic positioning pin is fixedly connected to one side of the outer side of the silicon carbide ceramic heat insulation sleeve b. The silicon nitride ceramic positioning pin is filled with aerogel for heat insulation. The silicon carbide ceramic heat insulation sleeve a has several positioning holes through it on one side corresponding to the silicon nitride ceramic positioning pin.
[0008] As a further embodiment of this utility model, the size of the positioning hole matches the outer size of the silicon nitride ceramic positioning pin, the protrusion on the back side of the silicon carbide ceramic heat insulation sleeve a passes through the samarium cobalt magnet a and is fixedly connected to the inside of the main mounting plate, and the silicon nitride ceramic positioning pin is inserted into the positioning hole.
[0009] As a further embodiment of this utility model, mounting grooves are distributed on both sides of the outer side of the auxiliary mounting plate, and a protective plate is fixedly connected inside the mounting groove. An extension baffle is integrally connected to the top of the protective plate, and the extension baffle of the protective plate is "convex arc-shaped".
[0010] As a further embodiment of this utility model, the bottom of the extension baffle of the protective plate is provided with a downward sliding surface, which is a "downward inclined plane". The top and bottom of the protective plate are flush with the top and bottom of the auxiliary mounting plate. The protective plate is located on one side of the main mounting plate. Both the top and bottom of the auxiliary mounting plate and the main mounting plate are provided with latches.
[0011] As a further embodiment of this utility model, the latch includes a movable latch and a fixed latch seat. A plurality of the movable latches are fixedly installed on the top and bottom sides of the main mounting plate, and a plurality of the fixed latch seats are integrally connected to the top and bottom sides of the secondary mounting plate. The shaft frame of the movable latch is rotatably sleeved on the fixed latch seat.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. Samarium cobalt magnets are resistant to high temperatures, ensuring magnetic stability under high-temperature environments. After embedding magnets at corresponding positions on the main and secondary mounting plates, silicon carbide ceramic heat insulation sleeves a and b are added to the outside of the Samarium cobalt magnets a and b. The ceramic sleeves have good heat insulation and wear resistance, and their high temperature resistance and low thermal conductivity can prevent the high temperature of the ring from being transferred to the magnets, avoiding magnetic attenuation. The surface of the heat insulation sleeves is flush with the panel, ensuring a flat and close fit of the magnetic surface, which can prevent the high temperature from being transferred to the magnets. During installation, the magnets attract and connect, allowing the main and secondary mounting plates to be installed quickly and accurately. The Samarium cobalt magnets a and b are embedded inside the panel and fixed by the mechanical strength of the panel material to prevent the magnets from falling off. During disassembly, a special non-magnetic high-temperature resistant tool is used to apply external force to separate the mounting plates, shortening maintenance time and making it suitable for scenarios where baffles are frequently replaced.
[0014] 2. The protective plate is fixed to the mounting groove of the auxiliary mounting plate with bolts. Its top and bottom are flush with the auxiliary mounting plate to form a complete protective surface. The arc-shaped extension baffle changes the trajectory of the splashes, preventing debris from entering the gap between the main mounting plate and the auxiliary mounting plate, and reducing the interference of debris on the magnetic connection. The extension baffle is "convex arc-shaped" and the bottom sliding surface is "sloping plane", which can guide the metal splashes generated during the rolling process to slide down the slope and avoid accumulation at the baffle connection. The sloping sliding surface allows dust, oxide scale, etc. to slide down automatically, reducing the frequency of daily cleaning and keeping the baffle surface clean. Attached Figure Description

[0023] Reference Figures 1-4 A baffle device for a ring rolling machine includes a baffle body 1, which includes a main mounting plate 2 and a secondary mounting plate 3. A samarium cobalt magnet a201 and a silicon carbide ceramic heat insulation sleeve a202 are fixedly embedded in the side of the main mounting plate 2 near the secondary mounting plate 3. One side of the silicon carbide ceramic heat insulation sleeve a202 is flush with the main mounting plate 2. A samarium cobalt magnet b302 and a silicon carbide ceramic heat insulation sleeve b303 are fixedly embedded in the side of the secondary mounting plate 3 that is in contact with the main mounting plate 2. The silicon carbide ceramic heat insulation sleeve b303 is sleeved on the outside of the samarium cobalt magnet b302 and is flush with the surface of the secondary mounting plate 3. The main mounting plate 2 and the secondary mounting plate 3 are magnetically connected by the samarium cobalt magnet a201 and the samarium cobalt magnet b302. The silicon carbide ceramic heat insulation sleeve a202 and the silicon carbide ceramic heat insulation sleeve b303 are in contact with each other.
[0024] In use, the samarium cobalt magnets are resistant to high temperatures, ensuring magnetic stability under high-temperature environments. After the magnets are embedded in the corresponding positions on the main mounting plate 2 and the auxiliary mounting plate 3, silicon carbide ceramic heat insulation sleeves a202 and b303 are added to the outside of the samarium cobalt magnets a201 and b302. The ceramic sleeves have good heat insulation and wear resistance, and their high temperature resistance and low thermal conductivity can prevent the high temperature of the rolling ring from being transferred to the magnets, thus avoiding magnetic attenuation. The surface of the heat insulation sleeves is flush with the panel, ensuring a flat and close fit of the magnetic attraction surface, which can prevent the high temperature from being transferred to the magnets. During installation, the magnets attract and connect, enabling the main mounting plate 2 and the auxiliary mounting plate 3 to be installed quickly and accurately. The samarium cobalt magnets a201 and b302 are embedded inside the panel and fixed by the mechanical strength of the panel material to prevent the magnets from falling off. During disassembly, a special non-magnetic high-temperature resistant tool is used to apply external force to separate the mounting plates, shortening maintenance time and making it suitable for scenarios where baffles are frequently replaced.
[0025] In this embodiment, a silicon nitride ceramic positioning pin 304 is fixedly connected to one side of the outer side of the silicon carbide ceramic heat insulation sleeve b303. The silicon nitride ceramic positioning pin 304 is filled with aerogel 305 for heat insulation. A number of positioning holes 2021 are opened through the silicon carbide ceramic heat insulation sleeve a202 on one side corresponding to the silicon nitride ceramic positioning pin 304.
[0026] When in use, silicon nitride ceramics have high high-temperature strength and low coefficient of thermal expansion. The positioning pin adopts a hollow design and is filled with aerogel 305 thermal insulation material to further reduce heat conduction and block heat conduction through the positioning pin. This prevents deformation caused by excessive temperature difference between the main mounting package and the secondary mounting plate 3. The magnetic adsorption and the ceramic positioning pin work together to achieve fast and accurate installation.
[0027] In this embodiment, the size of the positioning hole 2021 matches the outer size of the silicon nitride ceramic positioning pin 304. The protrusion on the back side of the silicon carbide ceramic heat insulation sleeve a202 passes through the samarium cobalt magnet a201 and is fixedly connected to the inside of the main mounting plate 2. The silicon nitride ceramic positioning pin 304 is inserted into the positioning hole 2021.
[0028] During use, the size of the positioning hole 2021 fits perfectly with the positioning pin, forming a mechanical lock after insertion, enhancing the stability of the magnetic connection and preventing misalignment during magnetic attraction. After the silicon nitride ceramic positioning pin 304 is fully inserted into the positioning hole 2021, its outer wall fits tightly against the hole wall, forming a double fixing structure of the baffle device: "magnetic baffle device + mechanical positioning baffle device". At the same time, the rigid fit between the positioning pin and the hole can reduce panel displacement caused by rolling vibration and ensure the stability of the baffle's constraint on the workpiece edge.
[0029] In this embodiment, mounting grooves 301 are distributed on both sides of the outer side of the auxiliary mounting plate 3. A protective plate 4 is fixedly connected inside the mounting groove 301. An extension baffle 401 is integrally connected to the top of the protective plate 4. The extension baffle 401 of the protective plate 4 is "convex arc".
[0030] In use, the protective plate 4 is fixed in the mounting groove 301 of the auxiliary mounting plate 3 by bolts. Its top and bottom are flush with the auxiliary mounting plate 3 to form a complete protective surface. The arc-shaped baffle 401 changes the trajectory of the splashing material, prevents debris from entering the gap between the main mounting plate 2 and the auxiliary mounting plate 3, and reduces the interference of debris on the magnetic connection.
[0031] In this embodiment, the bottom of the extension baffle 401 of the protective plate 4 is provided with a downward sliding surface 402, which is a "downward inclined plane". The top and bottom of the protective plate 4 are flush with the top and bottom of the auxiliary mounting plate 3. The protective plate 4 is located on one side of the main mounting plate 2. Both the auxiliary mounting plate 3 and the main mounting plate 2 are provided with latches 5 at their top and bottom.
[0032] When in use, the baffle 401 is "convex arc-shaped" and the bottom sliding surface 402 is "sloping plane". It can guide the metal spatter generated during the rolling process to slide down the slope and avoid accumulating at the baffle connection. The sloping sliding surface 402 allows dust, oxide scale and other particles to slide down automatically, reducing the frequency of daily cleaning and keeping the baffle surface clean.
[0033] In this embodiment, the latch 5 includes a movable latch 501 and a fixed latch 502. A plurality of movable latches 501 are fixedly installed on the top and bottom sides of the main mounting plate 2, and a plurality of fixed latches 502 are integrally connected to the top and bottom sides of the auxiliary mounting plate 3. The shaft frame of the movable latch 501 is rotatably sleeved on the fixed latch 502.
[0034] In use, the movable latch 501 on the top and bottom of the main mounting plate 2 and the fixed latch 502 of the auxiliary mounting plate 3 are hinged by the shaft. After being fastened, they are locked by bolts to form a double connection of "magnetic attraction + latch 5". The latch 5 assists the magnetic attraction connection to prevent the panel from loosening when the magnet's magnetism weakens slightly at high temperatures. It is especially suitable for heavy load rolling conditions. The latch and the fixed latch 502 are made of high temperature alloy, and the shaft bracket uses ceramic bearings to avoid lubrication failure at high temperatures.
[0035] As can be seen from the above description, the above embodiments of this utility model achieve the following technical effects: Samarium cobalt magnets a201 and b302 are respectively embedded on the corresponding surfaces of the main mounting plate 2 and the secondary mounting plate 3. Utilizing the principle of opposite poles attracting, the two mounting plates automatically adhere and stick together when they are close. Silicon carbide ceramic heat insulation sleeves a202 and b303 respectively wrap around the magnets, and their surfaces are flush with the panel, ensuring not only heat insulation but also a flat magnetic surface for rapid pre-positioning. The silicon nitride ceramic positioning pins 304 on the secondary mounting plate 3 are precisely matched to the positioning holes 2021 on the main mounting plate 2. During installation, the positioning pin is aligned with the positioning hole 2021 and inserted. Utilizing the high strength and low coefficient of thermal expansion of silicon nitride ceramic at high temperatures, it can maintain high-precision fit even in high-temperature environments, forming a mechanical lock, enhancing the stability of the magnetic connection, preventing installation misalignment, effectively resisting rolling vibration, maintaining the baffle's stable constraint on the workpiece edge, and improving workpiece processing accuracy. The protective plate 4 is fixed to the mounting grooves 301 on both sides of the sub-mounting plate 3 by bolts, with its top and bottom flush with the sub-mounting plate 3, forming a complete protective surface. The arc-shaped extension baffle 401 and the downward sliding surface 402 design of the protective plate 4 can effectively change the trajectory of metal spatter, guiding it to slide down the inclined surface, preventing debris from entering the gaps in the mounting plate and interfering with the magnetic connection, reducing the frequency of daily cleaning, and extending the service life of the baffle device. Meanwhile, the movable latches 501 and fixed buckles 502 at the top and bottom of the main mounting plate 2 and the auxiliary mounting plate 3 are hinged by a shaft, forming a dual connection structure of "magnetic attraction + latch 5", which further strengthens the baffle and ensures its stability during use. Even if the magnetism weakens slightly at high temperatures, the latch 5 can still provide additional fastening force, which is especially suitable for heavy load rolling conditions. In addition, the latches and fixed buckles 502 are made of high-temperature alloys, and the shaft frame uses ceramic bearings to avoid lubrication failure at high temperatures, ensuring the stability and reliability of the latch 5 mechanism and guaranteeing the normal operation of the baffle under complex working conditions.
[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
