Description

Technical Field

[0001] This utility model relates to the field of casting and rolling equipment technology, specifically to a continuous casting and rolling equipment for high-strength magnesium alloy plates. Background Technology

[0002] Magnesium alloys have advantages such as low density, high specific strength and specific stiffness, and good damping and vibration reduction properties, and have broad application prospects in aerospace, automotive, electronics and other fields.

[0003] In the prior art, such as in publication number CN203900096U, a continuous casting and rolling forming apparatus for a dual-continuous-phase composite plate is disclosed. The method includes the following steps: a feeding step: feeding a pre-formed porous ceramic plate into a molten metal solution; an impregnation step: the molten metal solution, under pressure, permeates into the porous ceramic to form a dual-continuous-phase composite material; and a forming step: rolling the surface of the composite material formed in the impregnation step, and cooling to form a metal plate layer on the surface of the composite material. The method provided by this utility model can realize the continuous forming of dual-continuous-phase composite materials in one step, and improves the mechanical properties of the metallic phase, thereby enhancing the wear resistance, heat resistance, and corrosion resistance of the material.

[0004] Currently, there are two main methods used in traditional casting and rolling equipment to produce magnesium alloy sheets: one is to use two rolls to cast and roll the sheet; the other is to use intermittent stamping to complete the casting and rolling process.

[0005] Although the twin-roll casting method has the ability to operate continuously and ensure the continuity of production, the pressure applied to the sheet is relatively low. This makes it difficult to meet the high-quality requirements such as the densification of the internal structure of the sheet when producing high-strength magnesium alloy sheets, thus affecting the key performance indicators such as the strength and toughness of the sheet.

[0006] While traditional stamping and casting methods can generate greater pressure and effectively improve the internal structure and performance of sheet metal, the production line must stop once each time the pressure plate is raised and lowered for stamping to ensure that the magnesium alloy sheet does not move during the stamping process. This results in poor production continuity and reduced production efficiency.

[0007] Therefore, this utility model provides a continuous casting and rolling equipment for high-strength magnesium alloy plates. Utility Model Content

[0008] In view of the difficulty of balancing pressure application and production continuity in traditional casting and rolling equipment, this utility model provides a continuous casting and rolling equipment for high-strength magnesium alloy plates, so as to achieve efficient and high-quality continuous production of high-strength magnesium alloy plates.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a continuous casting and rolling equipment for high-strength magnesium alloy plates, comprising a frame, a drive assembly at the top of the frame, two fixing assemblies inside the frame, the two fixing assemblies being symmetrically distributed vertically, and sliding assemblies on the exterior of each of the two fixing assemblies; each fixing assembly includes a fixing plate, and limit blocks are symmetrically installed near the edges of the opposing side surfaces of the two fixing assemblies, the limit blocks being arranged along the width direction of the fixing plate, and support blocks being installed on the opposing side surfaces of the two fixing assemblies away from the limit blocks; the sliding assembly includes a pressure plate, two pressure plates being disposed between the two fixing plates, L-shaped side plates being installed on the outer walls of the left and right sides of the pressure plates, the L-shaped side plates extending towards the limit blocks, multiple rollers being rotatably arranged between the opposing side surfaces of the two L-shaped side plates, multiple rollers being rotatably arranged on the inner wall of one side of the L-shaped side plate away from the rollers, a connecting plate being installed between the opposing side surfaces of the two L-shaped side plates, and a spring being installed between the connecting plate and the support block.

[0010] Preferably, the roller shaft is arranged along the width direction of the pressure plate, the outer wall of the roller shaft is in contact with the surfaces of the pressure plate and the fixed plate, the roller wheel is arranged parallel to the roller shaft, and the outer wall of the roller wheel is in contact with the other side surface of the fixed plate and the inner wall of one side of the L-shaped side plate, respectively.

[0011] Preferably, the drive assembly includes a motor mounted on the top surface of the frame, a connecting rod mounted on the output shaft end of the motor, and an eccentric shaft mounted on one side of the outer wall of the connecting rod near the edge.

[0012] Preferably, the drive assembly further includes a vertical rod that passes through and slides on the top surface of the frame. The bottom surface of the vertical rod is fixedly connected to the top surface of the upper fixed plate.

[0015] This invention provides a continuous casting and rolling equipment for high-strength magnesium alloy plates. Compared with the prior art, it has the following advantages:

[0016] 1. This high-strength magnesium alloy sheet continuous casting and rolling equipment, when the upper fixed component moves down, the upper and lower pressure plates move closer together to cast and roll the magnesium alloy sheet. When the sheet is conveyed between the two pressure plates, the restraining and pulling forces generated overcome the spring thrust to compress it, and the pressure plates move with the sheet. When the upper fixed component moves up, the pressure plates move up synchronously. After losing the restraining force, the spring pushes the connecting plate to reset the pressure plates so that the next casting and rolling can be carried out. This allows for continuous sheet passage and stamping and casting operations, improving the casting and rolling effect and production continuity.

[0017] 2. This high-strength magnesium alloy sheet continuous casting and rolling equipment reduces the friction between the sliding component and the fixed component by rolling the rollers and rollers between the L-shaped side plates on both sides of the pressure plate, so that the pressure plate can slide smoothly relative to the fixed plate.

[0018] 3. This high-strength magnesium alloy sheet continuous casting and rolling equipment adjusts the casting gap between the two fixed components by rotating a knob, which moves the threaded sleeve on the threaded rod and drives the lower fixed plate to move up and down to accommodate the thickness of the magnesium alloy sheet.

[0026] 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.

[0027] This utility model provides two technical solutions:

[0028] Figures 1-6 The first embodiment is shown: a continuous casting and rolling equipment for high-strength magnesium alloy plates, including a frame 1, a drive assembly 2 on the top of the frame 1, and two fixing assemblies 3 inside the frame 1, which are symmetrically distributed vertically. Each fixing assembly 3 has a sliding assembly 4 on its exterior. Each fixing assembly 3 includes a fixing plate 31. Limiting blocks 32 are symmetrically installed near the edges of the opposing surfaces of the two fixing assemblies 3, with the limiting blocks 32 arranged along the width direction of the fixing plate 31. The positions of the opposing surfaces of the two fixing assemblies 3 away from the limiting blocks 32 are... The sliding assembly 4 includes a support block 33 and a sliding component 4. Two pressure plates 41 are positioned between two fixed plates 31. L-shaped side plates 42 are installed on the outer walls of both sides of the pressure plates 41, extending towards the limiting block 32. Multiple rollers 43 are rotatably mounted between the opposing surfaces of the two L-shaped side plates 42. Multiple rollers 44 are rotatably mounted on the inner wall of one side of the L-shaped side plate 42 away from the rollers 43. A connecting plate 45 is installed between the opposing surfaces of the two L-shaped side plates 42, and a spring 46 is installed between the connecting plate 45 and the support block 33. The rollers 43 are positioned along the width of the pressure plates 41, with their outer walls contacting the surfaces of the pressure plates 41 and the fixed plates 31. The rollers 44 are parallel to the rollers 43, with their outer walls contacting the other surface of the fixed plate 31 and the inner wall of one side of the L-shaped side plate 42, respectively. The drive assembly 2 includes a motor 21 mounted on the top surface of the frame 1. A connecting rod 22 is mounted on the output shaft end of the motor 21, and an eccentric shaft 23 is mounted on one side of the outer wall of the connecting rod 22 near the edge. The drive assembly 2 also includes a vertical rod 24 that passes through and slides on the top surface of the frame 1. The bottom surface of the vertical rod 24 is fixedly connected to the top surface of the upper fixing plate 31. A horizontal plate 26 is mounted on the top surface of the vertical rod 24, and a straight groove 25 that mates with the eccentric shaft 23 is opened on the outer surface of the horizontal plate 26.

[0029] Specifically, the motor 21 is started, which drives the connecting rod 22 to rotate, causing the eccentric shaft 23 to make a circular motion. The eccentric shaft 23 slides in the straight groove 25 of the horizontal plate 26, driving the vertical rod 24 to move up and down reciprocally, causing the upper fixed component 3 to move up and down. When the upper fixed component 3 moves down, the upper and lower pressure plates 41 move closer together, casting and rolling the magnesium alloy sheet. When the sheet is conveyed between the two pressure plates 41, the restraining and pulling forces generated overcome the pushing force of the spring 46 to compress it. The pressure plate 41 moves with the sheet, and the roller shaft 43 and roller 44 between the L-shaped side plates 42 roll, reducing the friction between the sliding component 4 and the fixed component 3, helping the pressure plate 41 to slide smoothly. When the upper fixed component 3 moves up, the pressure plate 41 moves up synchronously. After the restraining force is lost, the spring 46 pushes the connecting plate 45 to reset the pressure plate 41 for the next casting and rolling.

[0030] Figures 1-6 The second embodiment is shown. The main difference from the first embodiment is that: multiple height adjustment components 5 are provided at the bottom of the lower fixing component 3. The height adjustment component 5 includes a threaded sleeve 51 installed on the bottom surface of the lower fixing plate 31. A threaded rod 52 is movably provided inside the threaded sleeve 51. The bottom end of the threaded rod 52 is fixedly connected to the inner bottom surface of the frame 1. A knob 53 is threadedly screwed onto the outer wall of the threaded rod 52, and the top surface of the knob 53 abuts against the bottom end of the threaded sleeve 51.

[0031] Specifically, by rotating the knob 53, the threaded sleeve 51 moves on the threaded rod 52, causing the lower fixing plate 31 to move up and down, thereby adjusting the casting gap between the two fixing components 3 to accommodate the thickness of the magnesium alloy sheet.

[0032] In this embodiment, a plurality of guide rods 6 are installed on the top surface of the upper fixed plate 31. The guide rods 6 slide through the inner top surface of the frame 1 and extend upward.

[0033] Specifically, the guide rod 6 ensures that the upper fixed plate 31 remains stable during the up-and-down movement.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] Working principle: First, the magnesium alloy sheet is passed between the upper and lower pressure plates 41 and pulled by an external traction device. Then, by starting the motor 21, the motor 21 drives the connecting rod 22 to rotate, and the eccentric shaft 23 on the connecting rod 22 moves in a circular motion. The eccentric shaft 23 slides in the straight groove 25 of the horizontal plate 26, driving the vertical rod 24 to move up and down reciprocally. The vertical rod 24 is fixedly connected to the upper fixed plate 31, thereby causing the upper fixed component 3 to move up and down. When the upper fixed component 3 moves down, the pressure plate 41 in the upper sliding component 4 moves closer to the lower pressure plate 41, thereby applying pressure to the magnesium alloy sheet for casting and rolling. During this process, when the magnesium alloy sheet is conveyed between the two pressure plates 41, it will generate pressure on the pressure plates 41. The restraining and pulling forces overcome the pushing force of the spring 46 on the connecting plate 45, causing the spring 46 to be compressed. This allows the pressure plate 41 to move along with the magnesium alloy sheet. As the pressure plate 41 moves, the rollers 43 and 44 between the L-shaped side plates 42 on both sides of the pressure plate 41 roll, reducing the friction between the sliding component 4 and the fixed component 3. This allows the pressure plate 41 to slide smoothly relative to the fixed plate 31. When the upper fixed component 3 moves upward, causing the pressure plate 41 to move upward synchronously, the two pressure plates 41 lose their restraining force. Under the pushing force of the spring 46, the connecting plate 45 is pushed to reset the pressure plate 41, facilitating the next pressurization and casting operation. This allows for continuous sheet material passage while also enabling stamping and casting operations, improving the casting effect and production continuity.
