Description

Technical Field

[0001] This utility model belongs to the technical field of metal material processing, specifically a device for removing black scale from the welded surface of metal materials. Background Technology

[0002] Metal welding surface black scale removal device is a professional equipment specifically designed to remove the oxide layer, slag residue, and black oxide scale from the heat-affected zone of the workpiece surface after welding. Its core principle is based on mechanical grinding (such as high-speed rotating grinding wheels and wire brushes). It can automatically adjust the removal parameters (such as pressure, speed, and power) according to the thickness of the black scale and the material of the workpiece, ensuring efficient removal of black scale while precisely controlling the wear of the substrate and avoiding excessive grinding that may affect the performance of the weld joint. The device is usually equipped with replaceable grinding heads or nozzles to adapt to various weld shapes, such as flat and curved surfaces.

[0003] Existing black scale removal devices for welded metal surfaces have certain shortcomings in use. Traditional black scale removal devices lack an adaptive adjustment structure and cannot adapt to different types of metal materials. For example, after welding, metal plates have a planar structure, and the black scale removal device only needs to move planarly at the welding position. However, after welding columnar metal materials, the weld seam has a ring structure, and the black scale removal device needs to move in a ring around the columnar metal material during the grinding operation. Traditional black scale removal devices cannot flexibly apply to plate-shaped and columnar metal materials, reducing their flexibility in use. At the same time, they cannot clean up the metal debris generated during black scale removal, resulting in limited functionality.

[0004] In summary, existing traditional black scale removal devices cannot flexibly apply to plate-shaped and cylindrical metal materials, cannot conform to the surface of cylindrical metal materials to make circular movements, and cannot clean up the metal debris generated during black scale removal, thus having limited functionality. Utility Model Content

[0005] This utility model provides a device for removing black scale from the welded surface of metal materials, which can solve the problems of traditional black scale removal devices in the prior art that cannot flexibly apply to plate-shaped and cylindrical metal materials, cannot conform to the surface of cylindrical metal materials for circular movement, and cannot clean up the metal debris generated during black scale removal, and have limited functionality.

[0006] A device for removing black scale from welded surfaces of metal materials includes a grinding base and two sets of limiting members. A grinding wheel is movably mounted at the lower center of the grinding base. The two sets of limiting members are movably mounted on both sides of the grinding base and are arranged in a mirror-symmetrical manner. Each limiting member includes a side-rotating bracket and a fixing plate. The side-rotating bracket is movably mounted on one outer surface of the fixing plate. Two sets of positioning wheels are movably mounted at the lower end of the side-rotating bracket, and the two sets of positioning wheels are movably mounted on both sides of the grinding wheel. A dust suction groove is provided at the lower part of the side-rotating bracket, and a dust suction pipe is installed at the upper center of the side-rotating bracket.

[0007] As a further technical solution of this utility model, a lifting plate is movably installed at the upper middle position of the grinding base. The interior of the grinding base is provided with a sliding groove for use with the lifting plate. By moving the lifting plate, the position of the positioning wheel can be adjusted by side rotation.

[0008] As a further technical solution of this utility model, a lifting base is fixedly installed on the upper outer surface of the lifting plate. A side-rotating support rod is movably installed between the lifting base and the side-rotating bracket. When the user presses down on the lifting base, the lifting base moves downward under the action of the lifting plate, thereby causing the lifting base to push and pull the side-rotating support rod downward. Because both ends of the side-rotating support rod are movably connected, the side-rotating support rod drives the side-rotating bracket to rotate during the downward movement, adjusting the angle between the side-rotating bracket and the fixed plate, so that the two sets of positioning wheels at the bottom of the side-rotating bracket... Figure 4 As shown, two sets of positioning wheels can be moved close to the surface of the metal tube, making it convenient for the grinding wheels to grind and clean the black skin at the weld seam of the tubular metal material.

[0009] As a further technical solution of this utility model, the grinding base and the lifting plate are locked together by fastening bolts. These fastening bolts can fix the lifting plate in different positions. When the user pulls the lifting base upwards, causing the lifting base to move the lifting plate upwards, the lifting base pulls the lifting plate upwards, causing the lifting plate to move the side-rotating bracket back to its original position, thus maintaining a horizontal relationship between the side-rotating bracket and the grinding base. Figure 1 As shown, the black skin at the weld seam on the surface of the metal plate can be polished.

[0010] As a further technical solution of this utility model, a vacuum cleaner is fixedly installed inside the lifting base. One end of the vacuum cleaner and the suction pipe are connected to each other. When the grinding wheel moves and grinds, the vacuum cleaner is used to generate suction in the suction groove under the side-rotating bracket through the suction pipe, thereby completing the cleaning operation of metal debris during the movement of the side-rotating bracket.

[0011] As a further technical solution of this utility model, the lifting base and the side-rotating support rod, as well as the side-rotating card seat and the side-rotating support rod, are all movably connected by a rotating rod. Both ends of the side-rotating support rod are in a movable state, allowing the use angle of the side-rotating support rod to be flexibly adjusted.

[0012] As a further technical solution of this utility model, the surfaces of the lifting base and the side-rotating bracket are provided with a steering groove for the side-rotating support rod. Both sides of the steering groove are open structures. By setting the steering groove, the rotation angle of the side-rotating support rod can be increased, so that the lifting base can make an angle change of 0.90 degrees under the action of the side-rotating support rod.

[0013] As a further technical solution of this utility model, a handle is fixedly installed at the middle position of the upper outer surface of the lifting base. The upper surface of the lifting base is provided with an exhaust groove. By holding the handle, the black skin removal device can be moved as a whole under the action of the positioning wheel. A control switch is installed on the surface of the handle.

[0014] As a further technical solution of this utility model, the grinding base is equipped with an electric motor for use with the grinding wheel, and the grinding base and the electric motor are driven by gears.

[0015] As a further technical solution of this utility model, the side-rotating bracket and the fixing plate are movably connected by a hinge, and the fixing plate and the grinding seat are fixed by a bolt. The angle of the side-rotating bracket and the fixing plate can be adjusted by using the hinge.

[0016] The beneficial effects of this utility model are as follows: By setting a limiting component, this utility model allows the black skin removal device for welded metal materials to switch freely between planar and arc-shaped movement states during use, making it flexible for grinding and cleaning black skin on plate-shaped or cylindrical metal materials. During use, the position of the positioning wheels can be adjusted by the movement of the lifting plate. The positioning wheels have two usage states: when the user presses down on the lifting base, the lifting base moves downward under the action of the lifting plate, thereby causing the lifting base to push and pull the side-rotating support rod downward. Because both ends of the side-rotating support rod are movable connections, the side-rotating support rod drives the side-rotating bracket to rotate during the downward movement, adjusting the angle between the side-rotating bracket and the fixed plate, so that the two sets of positioning wheels at the bottom of the side-rotating bracket... Figure 4 As shown, two sets of positioning wheels can be moved close to the surface of the metal tube, which makes it convenient for the grinding wheel to grind and clean the black skin at the weld position of the tubular metal material. The angle of the side-rotating bracket can be adjusted according to the position of the lifting base. The side-rotating brackets at different angles can be used to fit the corresponding diameter of the columnar metal material through the positioning wheels, which makes it convenient for the grinding wheel to move in a circle around the weld position of the columnar metal material.

[0017] When the user pulls the lifting base upwards, causing the lifting base to move the lifting plate upwards, the lifting base pulls the lifting plate upwards, causing the lifting plate to move the side-rotating bracket back to its original position, thus maintaining a horizontal position between the side-rotating bracket and the grinding seat. Figure 1 As shown, the black skin at the weld seam on the surface of the metal plate can be polished.

[0018] By configuring a suction pipe and a vacuum cleaner, the use of the side-rotating bracket is optimized when using the black scale removal device on the welded surface of the metal material. The lower part of the side-rotating bracket has a suction cleaning structure that can perform synchronous cleaning operations as the black scale removal device moves. When the grinding wheel moves and grinds, the vacuum cleaner, through the suction pipe, generates suction in the suction groove at the bottom of the side-rotating bracket, thereby completing the cleaning operation of metal debris during the movement of the side-rotating bracket and improving its usage effect.

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] like Figures 1-4As shown, a device for removing black scale from the welded surface of metal materials includes a grinding base 2 and two sets of limiting members 10. A grinding wheel 11 is movably installed at the lower middle position of the grinding base 2. The two sets of limiting members 10 are respectively movably installed on both sides of the grinding base 2 and are arranged in a mirror symmetrical manner. Each limiting member 10 includes a side-rotating bracket 14 and a fixing plate 15. The side-rotating bracket 14 is movably installed on one side of the outer surface of the fixing plate 15. Two sets of positioning wheels 17 are movably installed at the lower end of the side-rotating bracket 14. The two sets of positioning wheels 17 are respectively movably installed on both sides of the grinding wheel 11. A dust suction groove is provided at the lower part of the side-rotating bracket 14, and a dust suction pipe 7 is installed at the upper middle position of the side-rotating bracket 14.

[0027] A lifting plate 8 is movably installed at the upper middle position of the grinding base 2. The interior of the grinding base 2 is provided with a sliding groove that works with the lifting plate 8. By moving the lifting plate 8, the position of the positioning wheel 17 can be adjusted by side rotation.

[0028] A lifting base 3 is fixedly installed on the upper outer surface of the lifting plate 8. A side-rotating support rod 6 is movably installed between the lifting base 3 and the side-rotating support 14. When the user presses down on the lifting base 3, the lifting base 3 moves downward under the action of the lifting plate 8, thereby causing the lifting base 3 to push and pull the side-rotating support rod 6 downward. Because both ends of the side-rotating support rod 6 are movably connected, the side-rotating support rod 6 drives the side-rotating support 14 to rotate during the downward movement, adjusting the angle between the side-rotating support 14 and the fixed plate 15, so that the two sets of positioning wheels 17 at the bottom of the side-rotating support 14 are in position. Figure 4 As shown, the two sets of positioning wheels 17 can be moved close to the surface of the metal tube 18, which makes it convenient for the grinding wheel 11 to grind and clean the black skin at the weld position of the tubular metal material.

[0029] The grinding base 2 and the lifting plate 8 are locked together by fastening bolts 9. Fastening bolts 9 can fix the lifting plate 8 in different positions. When the user pulls the lifting base 3 upwards, causing the lifting base 3 to move the lifting plate 8 upwards, the lifting base 3 pulls the lifting plate 8 upwards, causing the lifting plate 8 to move the side-rotating bracket 14 back to its original position, keeping the side-rotating bracket 14 and the grinding base 2 in a horizontal state. Figure 1 As shown, the black skin at the weld seam on the surface of metal plate 1 can be polished.

[0030] A vacuum cleaner 13 is fixedly installed inside the lifting base 3. One end of the vacuum cleaner 13 and the suction pipe 7 are connected to each other. When the grinding wheel 11 moves and grinds, the vacuum cleaner 13 is used to generate suction in the suction groove at the bottom of the side-rotating bracket 14 through the suction pipe 7, thereby completing the cleaning operation of metal debris during the movement of the side-rotating bracket 14.

[0031] The lifting base 3 and the side-rotating support rod 6, as well as the side-rotating bracket 14 and the side-rotating support rod 6, are all connected by a rotating rod. Both ends of the side-rotating support rod 6 are in a movable state, allowing the angle of use of the side-rotating support rod 6 to be flexibly adjusted.

[0032] The surfaces of the lifting base 3 and the side-rotating bracket 14 are both provided with a steering groove 16 for the side-rotating support rod 6. Both sides of the steering groove 16 are open structures. The rotation angle of the side-rotating support rod 6 can be increased by setting the steering groove 16, so that the lifting base 3 can make an angle change of 0.90 degrees under the action of the side-rotating support rod 6.

[0033] A handle 4 is fixedly installed at the middle of the upper outer surface of the lifting base 3. The upper surface of the lifting base 3 is provided with an exhaust groove 5. By holding the handle 4, the entire black skin removal device can be moved under the action of the positioning wheel 17. A control switch is installed on the surface of the handle 4.

[0034] The grinding base 2 is equipped with an electric motor 12 that works with the grinding wheel 11. The grinding base 2 and the electric motor 12 are driven by gears.

[0035] The side-rotating bracket 14 and the fixed plate 15 are movably connected by a hinge, and the fixed plate 15 and the grinding base 2 are fixed by a bolt. The angle of the side-rotating bracket 14 and the fixed plate 15 can be adjusted by using the hinge.

[0036] A device for removing black scale from welded metal surfaces allows for flexible switching between planar and arc-shaped movement, making it suitable for grinding and cleaning black scale on plate-shaped or cylindrical metal materials. During use, the position of the positioning wheels 17 can be adjusted by moving the lifting plate 8. The positioning wheels 17 have two operating states: when the user presses down on the lifting base 3, the lifting base 3 moves downward under the action of the lifting plate 8, causing the lifting base 3 to push and pull the side-rotating support rod 6 downward. Because both ends of the side-rotating support rod 6 are movable, the side-rotating support rod 6 drives the side-rotating bracket 14 to rotate during its downward movement, adjusting the angle between the side-rotating bracket 14 and the fixed plate 15, so that the two sets of positioning wheels 17 at the bottom of the side-rotating bracket 14 are positioned as follows: Figure 4 As shown, the two sets of positioning wheels 17 can be moved close to the surface of the metal tube 18, which makes it convenient for the grinding wheel 11 to grind and clean the black skin at the weld position of the tubular metal material. The angle of the side-rotating bracket 14 can be adjusted according to the position of the lifting base 3. The side-rotating bracket 14 at different angles can be attached to the columnar metal material of the corresponding diameter through the positioning wheels 17, which makes it convenient for the grinding wheel 11 to move in a ring around the weld position of the columnar metal material.

[0037] When the user pulls the lifting base 3 upwards, causing the lifting base 3 to move the lifting plate 8 upwards, the lifting base 3 pulls the lifting plate 8 upwards, causing the lifting plate 8 to move the side-rotating bracket 14 back to its original position, thus maintaining a horizontal relationship between the side-rotating bracket 14 and the grinding base 2. Figure 1 As shown, the black skin at the weld seam on the surface of metal plate 1 can be polished.

[0038] By setting up the suction pipe 7 and the vacuum cleaner 13, the use of the side-rotating bracket 14 is optimized when the black skin removal device for the welded surface of the metal material is used. The lower part of the side-rotating bracket 14 has a suction cleaning structure, which can perform synchronous cleaning operation with the movement of the black skin removal device. When the grinding wheel 11 moves and grinds, the vacuum cleaner 13 is used to generate suction in the suction groove at the bottom of the side-rotating bracket 14 through the suction pipe 7, thereby completing the cleaning operation of metal debris during the movement of the side-rotating bracket 14 and improving its use effect.

[0039] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
