Description

Technical Field

[0001] The present invention relates to the technical field of intelligent equipment, and in particular to a MgO spraying device for silicon steel. Background Art

[0002] Steel is a vital raw material for national production and construction, playing a crucial role in the national economy, aerospace, and military industries. Silicon steel production and manufacturing technology is a key indicator of national steelmaking performance. Silicon steel is primarily used in infrastructure such as power grids and rail transit, and high-end silicon steel production and manufacturing technology is crucial to national economic production and construction. However, due to the inherent characteristics of ring annealing furnaces, silicon steel coils experience radial temperature differences during heating and cooling, leading to uneven stresses between the inner and outer layers of the coil and the core. Ultimately, compressive stresses can cause plastic deformation and adhesion of the coil. Extensive practical experience has shown that prior to high-temperature annealing in the ring furnace, a special MgO inhibitor should be applied to the end faces of the silicon steel coils to mitigate this uneven heating and cooling.

[0003] Currently, coating the ends of silicon steel coils is primarily done manually. This is labor-intensive, inefficient, and results in inconsistent coating quality and uneven edge crack prevention, severely impacting silicon steel output quality and preventing the maximization of silicon steel production efficiency. Intelligent manufacturing design for silicon steel spraying is needed to achieve automated coating of silicon steel coil ends.

[0004] In summary, the quality of the MgO inhibitor coating process for silicon steel significantly impacts the quality of silicon steel output, and this quality needs to be improved through automated design of the silicon steel spraying process.

DETAILED DESCRIPTION

[0032] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0033] Reference Figures 1 to 7 As shown, the present invention provides a MgO spraying device for silicon steel, comprising a frame 1, a protective cover fixedly provided on one side of the frame, and the protective cover 2 is made of flexible material;

[0034] Feeding structure 3, the feeding structure is fixed on the side opposite to the frame and the protective cover;

[0035] A drive structure 4 is provided on the frame and located inside the protective cover; a third ball joint rod 4-1 is provided on the side of the drive structure away from the frame, and the drive structure controls the spatial position of the third ball joint rod;

[0036] The spraying structure 5 is fixed on the protective cover, and a third ball joint rotation center 5-1 is provided in the area where the spraying structure is located inside the protective cover. The spraying structure is connected to the driving structure in a ball joint manner through the third ball joint rotation center and the third ball joint rod, and the spraying structure is connected to the feeding structure; in the process of the driving structure controlling the spatial position of the spraying structure, the protective cover produces corresponding deformation with the use of the spraying structure (this is why the protective cover uses flexible materials).

[0037] Spring limiting system 6, the spring limiting system is located between the frame and the spraying structure to ensure that the spatial posture of the spraying structure remains unchanged.

[0038] This embodiment provides a driving structure and a spraying structure, which are connected by a ball joint. The driving structure is used to control the spatial position of the spraying structure. A spring limiting system is provided between the frame and the spraying structure. The spring limiting system is used to correct the spatial posture of the spraying structure, so that the spatial posture of the spraying structure remains unchanged during the use of the device. A protective cover is provided, which is made of a flexible material, such as plastic film paper, and completely wraps the spraying driving device. The protective cover produces corresponding deformation as the spatial position of the spraying structure changes. This device uses a driving structure and a spring limiting system to only change the spatial position of the spraying structure without changing the spatial posture of the spraying structure (that is, the spraying structure as a whole moves up and down and left and right, but does not rotate), and effectively isolates the spray area from the equipment area through the protective cover. This device realizes MgO spraying operation on the end face of silicon steel, and has the characteristics of high cost performance, easy maintenance, stability and high efficiency.

[0039] Specifically, the driving structure also includes a first hydraulic cylinder 4-2, a second hydraulic cylinder 4-3, a third hydraulic cylinder 4-4, a pin 4-5 and an intersection fixing part 4-6. The non-hydraulic rod ends of the first, second and third hydraulic cylinders are arranged on the frame in a ball-jointed manner, and the fixed position is determined according to the spatial position adjustment area of ​​the spraying structure; one end of the intersection fixing part is fixedly connected to the hydraulic rod end of the first hydraulic cylinder, and the other end of the intersection fixing part is fixedly connected to the non-ball-jointed end of the third ball-jointed rod; the hydraulic rod ends of the second hydraulic cylinder and the third hydraulic cylinder are connected by a hinge group The components are hinged on the pin shaft (see the first hinge component 4-7 and the second hinge component 4-8 in the embodiment in the figure, one side of the first hinge component is fixedly connected to the hydraulic rod end of the second hydraulic cylinder, and the other side of the first hinge component is sleeved on the pin shaft and rotates around the pin shaft; the connection method of the second hinge component and the third hydraulic cylinder is the same as above), a second ball joint rod 4-9 is provided on the end of the pin shaft close to the intersection component, and a second ball joint rotation center 4-10 is provided in the middle of the intersection fixing component, and the pin shaft is connected to the intersection fixing component in a ball joint manner through the second ball joint rod and the second ball joint rotation center.

[0040] In this embodiment, the spatial position of the third ball joint is changed by controlling the extension and retraction of the first, second, and third hydraulic cylinders, thereby changing the spatial position of the spray structure. In the illustrated embodiment, due to the insufficient length of the second ball joint and the pin, a short circuit 4-13 is provided between the second ball joint and the pin to facilitate their secure connection. This provides an indirect secure connection between the two.

[0041] In some other embodiments, the first, second and third hydraulic cylinders are replaced by air cylinders or electric push rods.

[0042] Furthermore, the axis of the hydraulic rod of the first hydraulic cylinder, the rotation center of the second ball joint, and the axis of the third ball joint rod coincide with each other, thereby avoiding circumferential rotation at the intersection fixing member.

[0043] Furthermore, a plurality of first ball joint rotation centers 4-11 are provided on the side of the frame located near the protective cover. The number and fixed positions of the first ball joint rotation centers are determined by the design positions of the connection points between the first, second, and third hydraulic cylinders and the frame. First ball joints 4-12 are provided at the non-hydraulic rod ends of the first, second, and third hydraulic cylinders. The first, second, and third hydraulic cylinders are connected to the frame via the first ball joints and the first ball joint rotation centers. In the illustrated embodiment, three sets of ball joint fixing holes 1-1 are provided on the frame, and the first ball joint is bolted into the frame's ball joint fixing holes.

[0044] Specifically, the spring limiting system includes several springs 6-1 of the same length and specifications (using the same springs, the spring length remains consistent, and they have sufficient elastic force). The springs are arranged parallel to each other, and the axis of the spring and the hydraulic rod of the first hydraulic cylinder are parallel. One end of each spring is fixed to the frame, and the other end is fixed to the spray structure. Under the action of the springs, the spatial posture of the spray structure remains unchanged. In the embodiment shown in the figure, a spring fixing hole 1-2 and a spring fixing seat 6-2 are provided on the frame. The spring fixing hole is located on the side of the ball joint fixing hole of the first hydraulic cylinder. The spring fixing seat is installed in the spring fixing hole of the frame by bolts. The spring fixing seat and the spray structure are both provided with connection points for fixing the springs (a first spring connection point 6-3 is provided on the spring fixing seat, and a second spring connection point 6-4 is provided on the spray structure).

[0045] Furthermore, there are four springs, and the quadrilateral formed by the spring fixing points on the spray structure is rectangular or rhombus-shaped (preferably square, as the square structure is the most stable); the rotation center of the third ball joint coincides with the intersection of the diagonals of the quadrilateral; the quadrilateral formed by the spring fixing points on the frame is rectangular or rhombus-shaped; the rotation center of the first ball joint of the first hydraulic cylinder coincides with the intersection of the diagonals of the quadrilateral. The two quadrilaterals formed by the fixing points at both ends of the spring are of the same shape and parallel to each other.

[0046] It is also possible to use 3 or more springs, with the springs forming a regular polygon at fixed points on the spray structure, with the rotation center of the third ball joint coinciding with the center point of the regular polygon. An appropriate number of springs needs to be selected based on the size of the device. Too many springs will increase the chances of interference during movement, while too few springs will have a greater impact on the accuracy of the spatial posture restriction of the spray structure.

[0047] Preferably, the length of the quadrilateral side is designed to be as large as possible. The larger the side length, the more stable the spatial posture of the spraying structure.

[0048] Specifically, the feeding structure includes a stirring tank 3-1, a diaphragm pump 3-2 and an air compressor 3-3. A feeding port 3-4 is provided on the upper part of the stirring tank, and a first feeding pipe 3-5 is provided at the bottom of the stirring tank, and the stirring tank is connected to the diaphragm pump through the first feeding pipe; a pressure inlet pipe 3-6 is provided on the air compressor, and the air compressor is connected to the diaphragm pump through the pressure inlet pipe; a second feeding pipe 3-7 is provided on the diaphragm pump, and an opening 1-3 is provided on the frame, and the second feeding pipe passes through the opening to connect the diaphragm pump and the spraying structure.

[0049] Specifically, the spraying structure also includes a leveling plate 5-2, a spray gun mounting base 5-3, and a spray gun 5-4. The leveling plate is fixed to the protective cover. The rotation center of the third ball joint is fixed to the flat surface of the leveling plate located inside the protective cover. The spray gun is mounted on the flat surface of the leveling plate located outside the protective cover via the spray gun mounting base, with the spray gun facing the end face of the silicon steel 7 to be sprayed. The second spring connection point is located on the flat surface of the leveling plate located inside the protective cover.

[0050] Furthermore, it includes a silicon steel seat 8 and a rubber pad 9 for supporting the silicon steel. The silicon steel seat and the rubber pad are arranged symmetrically, with the silicon steel seat located on the floor in front of the spray structure, and the rubber pad located on the contact surface between the silicon steel seat and the silicon steel. This device can withstand heavy loads and other harsh working conditions and has a long service life. Because the drive structure restricts the spatial movement of the spray structure, it is primarily suitable for circular spraying of silicon steel.

[0051] High cost performance: Due to its simple structure, this device does not involve high-precision transmission mechanisms and requires fewer customized parts. It only requires selecting suitable hydraulic cylinders, ball joints, springs, and spray guns, and paying attention to the matching points of each component during assembly.

[0052] Easy maintenance: The specially formulated MgO solution easily solidifies and agglomerates when exposed to air, and is also corrosive. This device features a wall-mounted drive structure and uses a rack and protective cover to completely isolate the spraying area from the equipment area. During equipment movement, agglomerated MgO will fall off the protective cover, allowing for direct replacement.

[0053] Stable and efficient: This device replaces manual brushing, with significantly improved efficiency and stable spraying quality, which is conducive to the production of high-quality silicon steel products.

[0054] The above are only preferred embodiments of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope of protection of the present invention.
