Description

Technical Field

[0001] This application relates to the field of sheet metal surface treatment technology, and more particularly to a through-type oxide scale treatment device. Background Technology

[0002] With economic development and technological progress, single metals or alloys can hardly meet the material performance requirements of industrial production. Therefore, metal composite plates made by layering dissimilar metals have emerged and have been applied in many industries such as corrosion protection, pressure vessel manufacturing, power construction, petrochemicals, pharmaceuticals, light industry, and automobiles.

[0003] Before composite manufacturing, single-layer metal sheets need to be polished to remove the oxide scale. For smaller metal sheets, the oxide scale is usually removed by hand-held grinder or shot peening. Chemical pickling can also be used to remove the oxide scale from titanium and titanium alloy sheets. However, for larger sheets, hand-held grinding is less efficient and requires polishing one side at a time. Chemical pickling is inconvenient and may require repeated processing of a single sheet to complete the process. Moreover, it is difficult to guarantee the surface quality of titanium and titanium alloy sheets. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing large-scale plate surface oxide scale treatment equipment has low processing efficiency and poor treatment effect.

[0005] Therefore, this utility model provides a through-type oxide scale treatment device.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A through-type scale removal device, comprising,

[0008] frame,

[0009] The transmission mechanism is used to convey the sheet metal;

[0010] Multiple grinding wheels are arranged along the length of the frame, and the grit number of the multiple grinding wheels gradually increases along the length of the frame. The multiple grinding wheels are used to grind the top and bottom surfaces of the board.

[0011] A dust removal mechanism is installed on the frame to collect the debris generated during grinding.

[0012] Furthermore, the transmission mechanism includes a first transmission component and a second transmission component. There are two first transmission components and multiple second transmission components. The multiple second transmission components are spaced apart between two first transmission components along the length of the frame, and adjacent grinding components are arranged between adjacent second transmission components.

[0013] Furthermore, the grinding wheel is slidably mounted on the frame along the Z-axis direction.

[0014] Furthermore, the frame is provided with a plurality of grinding components along its length, each grinding component having two grinding wheels, and the two grinding wheels in each grinding component are symmetrically arranged on the upper and lower sides of the plate.

[0015] Furthermore, each of the aforementioned polishing components has two polishing wheels with the same grit size.

[0016] Furthermore, along the axial direction of the grinding wheel, the axial length of the grinding wheel is greater than or equal to the width of the plate.

[0017] Furthermore, the dust removal mechanism includes multiple suction pipes, which are mounted on the frame. The number of suction pipes is the same as the number of grinding components, and the suction pipes are located behind the corresponding grinding components.

[0018] Furthermore, within the YZ plane, the suction pipe is shaped like a trumpet and covers the polishing mechanism. The suction pipe is located above the material, and the larger end of the suction pipe is open towards the material.

[0019] Furthermore, the length of the larger end of the suction pipe along the axial direction of the grinding wheel is greater than or equal to the width of the board.

[0020] Furthermore, the lower end of the suction pipe is configured in the shape of a duckbill and is positioned between the two grinding wheels in the opposing grinding assembly.

[0021] The beneficial effects of this utility model are that it utilizes a transmission mechanism to form a through-type grinding structure and employs multiple grinding wheels to progressively refine the grinding of the board surface, thereby achieving rapid treatment of the oxide layer on the board surface. When the board passes through the multiple grinding components, the second transmission components are spaced between the grinding wheels, which not only ensures the transport of the board but also makes way for the grinding wheels located below, facilitating the grinding of the lower surface of the board.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] A through-type oxide scale treatment device includes a frame 1, a cover 2, a conveying mechanism 3, a grinding mechanism 4, and a dust removal mechanism 5. The length of the frame 1 is arranged along the front-to-back direction (in this application, the positive direction of the X-axis is the front, and the negative direction of the X-axis is the back).

[0031] The transmission mechanism 3 includes a first transmission component 31 and a second transmission component 32. There are two first transmission components 31, which are respectively located at the front and rear ends of the frame 1. There are multiple second transmission components 32, which are spaced apart between the two first transmission components 31 along the length of the frame 1.

[0032] The first transmission component 31 includes multiple guide rollers 311 and a first drive source 312. The axial direction of the guide rollers 311 is arranged in the horizontal direction. The multiple guide rollers 311 are evenly spaced along the length direction of the frame 1. The ends of the guide rollers 311 can be coaxially connected to gears. The multiple guide rollers 311 are driven by chains and end gears to achieve sprocket transmission, so as to realize the synchronous rotation of the multiple guide rollers 311. The guide rollers 311 are rotatably connected to the frame 1 through outer spherical bearings for transmitting plates. The first drive source 312 is connected to the frame 1 and is used to control the rotation of the guide rollers 311.

[0033] The second transmission assembly 32 includes a mounting frame, rollers 321, and a second drive source 322. Multiple rollers 321 are arranged axially in a horizontal direction, evenly spaced along the length of the frame 1. The rollers 321 are connected to the frame 1 via the mounting frame. Gears can also be coaxially connected to the ends of the rollers 321. The multiple rollers 321 are driven by a chain and the end gears, achieving synchronous rotation. The second drive source 322 is connected to the mounting frame and drives the rollers 321 to rotate. The second drive source 322 is a flap-wheel fine-tuning drive motor 413. The top of the rollers 321 and the top of the guide rollers 311 are located in the same horizontal plane, defined as the base plane. The transmission mechanism 3 transmits the sheet material from front to back.

[0034] The grinding mechanism 4 includes a frame and a plurality of grinding components 41 arranged along the direction of the frame 1, with adjacent grinding components 41 arranged between adjacent second transmission components 32. Each grinding assembly 41 includes a set of grinding wheels 414 arranged opposite each other on the upper and lower sides of the base surface. Each set of grinding wheels 414 includes a Z-axis adjustment component 411, a mounting base 412, a drive motor 413, and a grinding wheel 414. The Z-axis adjustment component 411 is connected to the frame. The Z-axis adjustment components 411 of the two grinding wheel sets in each grinding assembly 41 are located on the upper and lower sides of the base surface. The mounting base 412 is connected to the output end of the Z-axis adjustment component 411. The drive motor 413 and the grinding wheel 414 are mounted on the mounting base 412. The grinding wheel 414 is located on the side of the drive motor 413 closer to the base surface. The grinding wheels 414 of the two grinding wheel sets in each grinding assembly 41 are symmetrically arranged on the upper and lower sides of the base surface. The drive motor 413 is used to drive the grinding wheel 414 to rotate. The motor adopts a flap drive motor 413.

[0035] The grit number of the grinding wheels 414 in the multiple grinding components 41 gradually increases from front to back. The grit number of the two grinding wheel 414 groups in each grinding component 41 is the same. Thus, the board is ground from coarse to fine step by step as it passes through the grinding mechanism 4. Along the axis of the grinding wheel 414, the axial length of the grinding wheel 414 is greater than or equal to the width of the board.

[0036] The dust removal mechanism 5 includes multiple suction pipes 51. The number of suction pipes 51 is the same as the number of polishing components 41. Each suction pipe 51 is opposite to a polishing component 41 and is located behind the corresponding polishing component 41. In the YZ plane, the suction pipe 51 is flared and covers the polishing mechanism 4. The suction pipe 51 is located above the base surface. The larger end of the suction pipe 51 is open and faces the base surface. The lower end of the suction pipe 51 is duckbill shaped and faces between the two polishing wheels 414 in the polishing component 41 opposite to it. The cover 2 covers the polishing mechanism 4. The end of the suction pipe 51 away from the base surface passes through the cover 2 and is connected to the smoke pipe.

[0037] The implementation principle of this application is as follows:

[0038] The distance between the grinding wheel 414 and the board is adjusted by the Z-axis control component, allowing the grinding wheel 414 to contact the board. The board is placed on the first transmission component 31 and moves from front to back toward the grinding mechanism 4. As the board passes through the grinding mechanism 4, multiple grinding wheels 414 grind the board step by step from coarse to fine. The grinding debris is discharged through the dust suction pipe 51, ultimately completing the grinding of the oxide scale on the surface of the board. The second transmission component 32 is spaced between the grinding wheels 414, which not only ensures the transport of the board but also makes way for the grinding wheel 414 located below, facilitating the grinding of the lower surface of the board.

[0039] Specifically, the first-stage grinding wheel 414 primarily targets the oxide scale on the surface of the base carbon steel plate, performing single-sided or double-sided treatment to achieve a cleanliness ≥ Sa2.5 and a roughness between Ra12.5 and Ra6.3 on the mating surface. The second-stage grinding wheel 414 then performs single-sided or double-sided fine grinding to achieve a surface roughness between Ra6.3 and Ra3.2. For oxide films on stainless steel and non-ferrous metal layers, they can directly enter the third-stage grinding wheel 414 for fine grinding without shot blasting, achieving a surface roughness between Ra6.3 and Ra3.2.

[0040] This application uses multiple 414 grinding wheels to perform progressively finer grinding on the surface of the board, thereby achieving rapid treatment of the oxide layer on the board surface.

[0041] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined by the scope of the claims.
