Description

Technical Field

[0001] This utility model relates to the field of steel pouring technology, and in particular to an electromagnetic suction type steel ladle stopper rod driving device. Background Technology

[0002] In a molten steel ladle, the ladle stopper is a key component. Its function is to precisely control the opening and closing of the ladle nozzle by moving it up and down, thereby regulating the flow of molten steel and ensuring the smooth progress of the pouring process. The precise operation of the stopper directly affects the control of the pouring speed, the stability of the pouring quality, and the improvement of casting production efficiency.

[0003] However, the stopper rods in molten steel ladles are currently replaced frequently. Due to differences in manufacturing processes and equipment, certain errors inevitably exist between ladles during manufacturing and assembly. These errors manifest as deviations in the relative position of the stopper rod and the casting machine's drive mechanism in the horizontal, vertical, and longitudinal directions. These deviations make it difficult for the casting machine's drive mechanism to automatically and accurately grasp and control the stopper rod, reducing the level of automation and system stability. Summary of the Invention

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0029] In this utility model, when directions (up, down, left, right, front, and back) are described, it is only for the convenience of describing the technical solution of this utility model, and does not indicate or imply that the technical features referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0031] In this utility model, unless otherwise explicitly defined, terms such as "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a direct connection or an indirect connection through an intermediate medium; a fixed connection, a detachable connection, or an integrally formed connection; a mechanical connection, an electrical connection, or a connection capable of mutual communication; or the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model based on the specific content of the technical solution.

[0032] Reference Figure 1 , Figure 2 As shown, this utility model discloses an electromagnetic attraction type steel ladle stopper rod driving device, which is installed on the transverse moving carriage 8 of the casting machine. The steel ladle stopper rod includes a stopper rod slide rod 1, comprising:

[0033] An armature component 2 is disposed on the stopper rod slide 1, and the armature component 2 is capable of floating radially along the stopper rod slide 1 and / or swinging along the axis of the stopper rod slide 1;

[0034] The driving mechanism includes a displacement driving mechanism 3 and an electromagnetic chuck 4. The electromagnetic chuck 4 is disposed on the radial side of the stopper rod slide 1. The electromagnetic chuck 4 can move towards the armature component 2 under the drive of the displacement driving mechanism 3, so that the electromagnetic chuck 4 and the armature component 2 are attracted to each other, and the stopper rod slide 1 is driven to rise and fall.

[0035] With the above settings, the armature component 2 can float radially and swing axially. The swing design can avoid the problem that the electromagnetic chuck 4 and the armature component 2 are not parallel, ensuring that the contact surfaces are fully in contact, improving the contact stability, and effectively adapting to the deviation of the position of the stopper rod slide rod 1 caused by the ladle manufacturing process and assembly error. This allows the electromagnetic chuck 4 and the armature component 2 to automatically adjust their positions, ensuring smooth docking.

[0036] In one embodiment, the armature component 2 includes a through hole through which the stopper slide 1 passes, the diameter of which is larger than the diameter of the stopper slide 1. This facilitates the installation of the armature component 2 and allows it to float and swing on the stopper slide 1, providing greater tolerance for the engagement of the electromagnetic chuck 4.

[0037] In one embodiment, the armature component 2 has an attraction surface 21 that contacts the electromagnetic chuck 4. The electromagnetic chuck 4 can quickly attract and release the armature component 2. It is a powerful electromagnetic chuck 4 used in surface grinders. The electromagnetic chuck 4 has multiple sets of coils and an iron core design inside, which provides strong magnetic force to ensure that the armature component 2 is firmly attracted to the surface of the chuck, so that the stopper rod slide 1 remains stable during the driving process and is not prone to slippage or displacement.

[0038] It should be noted that the armature component 2 includes armature material located at the suction plane 21 and a sleeve structure sleeved on the stopper rod slide 1.

[0039] In one embodiment, an upper stop block 5 and a lower stop block 6 are respectively disposed on the stop rod slide 1 and located on both axial sides of the armature component 2, the upper stop block 5 and the lower stop block 6 being able to contact the two axial ends of the armature component 2.

[0040] In one embodiment, the upper stop 5 and / or the lower stop 6 have hook plates 7 extending from their sides, capable of contacting the armature component 2 when it swings. The upper stop 5 and the lower stop 6 effectively limit the axial displacement range of the armature component 2, preventing it from moving excessively or detaching from the suction cup's engagement range. The hook plates 7 are designed to provide a limit when the armature component 2 swings, ensuring that the armature component 2 adheres to the surface of the electromagnetic chuck 4 and guaranteeing the stability of the engagement process.

[0041] Specifically, a hook plate 7 is only provided on the upper stop block 5. The upper stop block 5 is fixed to the stop rod slide 1 with a through pin or bolt, and the hook plate 7 is at a certain distance from the armature component 2. The upper stop block 5 restricts the upward movement of the armature component 2, and the armature component 2 can swing slightly to avoid non-parallelism with the suction surface of the electromagnetic chuck 4 and automatically fit and meet it. The lower stop block 6 can utilize the original parts on the stop rod slide 1 (such as the top block on the manual lifting mechanism), reducing additional processing costs. The axial displacement of the armature component 2 by the upper stop block 5 and the lower stop block 6 causes the armature component 2 to drive the stop rod slide 1 for precise flow control casting.

[0042] In one embodiment, the displacement driving mechanism 3 includes an axial driving part 31 and a radial driving part 32. The radial driving part 32 is connected to the axial driving part 31 and is used to drive the axial driving part 31 to move radially. The axial driving part 31 is connected to the electromagnetic chuck 4 and is used to drive the electromagnetic chuck 4 to move axially. The displacement driving mechanism 3 achieves precise movement of the electromagnetic chuck 4 through both radial and axial parts, ensuring that the chuck can accurately approach and engage the armature component 2. The combination of the radial driving part 32 and the axial driving part 31 allows for flexible adjustment of the position of the electromagnetic chuck 4 to adapt to various working conditions. After the electromagnetic chuck 4 engages, it can stably drive the stop rod slide 1 to achieve precise lifting and lowering, ensuring reliable control of the molten steel outlet.

[0043] In one embodiment, the axial drive unit 31 and the radial drive unit 32 include a servo electric cylinder, a servo screw assembly, or a rack and pinion transmission mechanism, and may also be a pneumatic cylinder drive mechanism, a hydraulic cylinder drive mechanism, a magnetic levitation linear drive mechanism, etc.

[0044] During operation, the electromagnetic chuck 4 is in a non-engaged state. The displacement drive mechanism 3 (including the axial drive part 31 and the radial drive part 32) adjusts the electromagnetic chuck 4 to the vicinity of the armature component 2. The radial drive part 32 drives the electromagnetic chuck 4 to approach the armature component 2 radially. When the electromagnetic chuck 4 approaches the armature component 2, the coil inside the chuck is energized to generate a strong magnetic field, which firmly attracts the armature component 2 to the surface of the chuck.

[0045] The armature component 2 can float and swing to automatically adjust its angle, ensuring that the suction cup and the suction surface of the armature component 2 are fully in contact; the axial drive unit 31 is activated, driving the electromagnetic suction cup 4 to move up or down along the axial direction; the armature component 2 drives the stop rod slide 1 to move synchronously through the suction force, completing the precise opening and closing operation of the molten steel outlet and adjusting the outflow of molten steel.

[0046] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
