Description

Technical Field

[0001] This application relates to the field of thin plate grinding, and more particularly to a thin plate grinding and rust removal device. Background Technology

[0002] Existing grinding and rust removal devices include a polishing wheel, a support, and a base. The workpiece is fixed on the support, and a handheld polishing wheel is used to contact the workpiece. Polishing is achieved through the relative movement of abrasive particles on the polishing wheel and the workpiece. However, handheld polishing is inefficient and poses certain risks, potentially causing injury.

[0003] Patent document CN115070570A discloses a surface polishing device for manufacturing and processing metal products for construction. It includes a processing table, a fixed plate mounted on top of the processing table, a polishing wheel on top of the processing table, two arc-shaped frames mounted on top of the processing table, a placement plate slidably mounted between the two arc-shaped frames and the fixed plate, a clamping mechanism on top of the placement plate, a polishing belt on the placement plate, and a driving mechanism mounted at the bottom of the processing table. In this invention, the polishing belt can polish the surface of a metal plate. The polishing belt can rotate within the arc-shaped frames via an adjusting shaft, thereby adjusting the angle of the polishing belt to accommodate metal plates with bevels or other metal products. It also facilitates polishing thin metal plates, improving the overall polishing efficiency of the device. However, it cannot achieve continuous polishing operations, affecting processing efficiency. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this application is to replace the traditional clamping mechanism with a magnetic wheel, in order to solve the problem of continuous polishing operations.

A polishing wheel is positioned directly above the conveyor belt; the axis of the polishing wheel is parallel to the magnetic wheel and rotates in the same direction; when the polishing wheel and the magnetic wheel work simultaneously, the bottom surface of the polishing wheel moves relative to the upper surface of the thin plate at the top of the conveyor belt, thereby polishing the top surface of the thin plate.

[0006] Preferably, there are multiple polishing wheels, and the multiple polishing wheels are arranged coaxially.

[0007] As a further preferred embodiment, lifting motors for adjusting the height of the polishing wheel are provided at both ends of the polishing wheel, thereby adjusting the relative distance between the bottom of the polishing wheel and the top of the conveyor belt to accommodate thin plates of different thicknesses.

[0008] Preferably, a base for fixing the conveyor belt and the magnetic wheel is provided below the conveyor belt.

[0009] Preferably, the magnetic wheel is provided with a first rotary motor for driving the magnetic wheel to rotate, and the polishing wheel is provided with a second rotary motor for driving the polishing wheel to rotate.

[0018] like Figure 1 As shown, this application provides a thin plate grinding and rust removal device, including a conveyor belt 3 for transporting thin plates; at the bottom of the conveyor belt 3, along the transport direction of the thin plates, there are two or more magnetic wheels 1 with their axes parallel to the width direction of the conveyor belt; below the conveyor belt 3, there is a base for fixing the conveyor belt 3 and the magnetic wheels 1.

[0019] The magnetic wheel 1 rotates to drive the conveyor belt 3, causing the thin plate on top of the conveyor belt 3 to move forward along the conveying direction, while the thin plate on top of the conveyor belt 3 is fixed by a magnetic field.

[0020] A polishing wheel 5 is fixed above the conveyor belt 3 via a polishing wheel bracket 4; the axis of the polishing wheel 5 is parallel to the magnetic wheel 1 and rotates in the same direction; a first rotary motor is provided on the magnetic wheel 1 to drive the magnetic wheel 1 to rotate, and a second rotary motor is provided on the polishing wheel 5 to drive the polishing wheel to rotate.

[0021] When the polishing wheel 5 and the magnetic wheel 1 are working, the bottom surface of the polishing wheel 5 moves relative to the upper surface of the thin plate at the top of the conveyor belt 3, thereby polishing the top surface of the thin plate. In some embodiments, there are multiple polishing wheels 5, and the multiple polishing wheels 5 are coaxially arranged. At both ends of the polishing wheel, there are lifting motors for adjusting the height of the polishing wheel 5, so that the relative distance between the bottom of the polishing wheel 5 and the top of the conveyor belt 3 can be adjusted to accommodate thin plates of different thicknesses. In other embodiments, both ends of the polishing wheel 5 extend through the width direction of the conveyor belt 3 to ensure that the polishing range covers the thin plate.

[0022] In some embodiments, the thin plate grinding and rust removal device further includes a central control device, wherein the first output end of the central control device is connected to the first rotary motor, the second output end is connected to the second rotary motor, and the third output end is connected to the lifting motor; to adjust the working state, rotation speed, rotation direction, or height of the magnetic wheel 1 and / or the polishing wheel 5.

[0023] The conveyor belt 3 is provided with a feeding device at the front end along the conveying direction to place the thin plate on the conveyor belt 3, and a collecting device is provided at the rear end along the conveying direction to collect the polished thin plate.

[0024] Figure 2 In one embodiment of this application, the magnetic wheel 1 is integrated with the roller using a permanent magnet, giving the roller a vertical magnetic attraction force. The magnetic field strength is approximately 0.8 T to 1.2 T. In this embodiment, the sheet metal workpiece has a thickness of 1.5 mm, dimensions of 1250 mm * 3000 mm, and is made of Q235 steel. The relative attraction between the magnetic wheel and the sheet metal workpiece can reach 160 N / m to 200 N / m. 2 Through the combined action of magnetic attraction and static friction between the conveyor belt 3 and the thin plate workpiece, the static friction force of the thin plate workpiece in the horizontal direction can reach 200 N / m. 2 In this way, even when passing under the polishing wheel 5, the movement of the polishing wheel 5 will not cause relative displacement between the thin plate workpiece and the belt.

[0025] In the diagram, the magnetic wheel 1 rotates in the direction of the blue arrow, causing the conveyor belt 3 to move in the direction of the green arrow at a linear speed of approximately 1000 mm / min. In this embodiment, two coaxially arranged polishing wheels 5 are used for polishing. During operation, the polishing wheels 5 are adjusted to a height suitable for the thickness of the thin plate workpiece and rotate in the direction of the red arrow. The sand particles on the surface of the polishing wheels 5 rub against the thin plate workpiece, fully polishing the thin plate workpiece between the polishing wheels 5 and the conveyor belt 3. The conveyor belt 3 continues to move. As the thin plate workpiece moves to the rear end of the conveyor belt 3, the magnetic field it experiences gradually decreases, thus naturally detaching from the thin plate grinding and rust removal device and entering the collection device located below the rear end of the conveyor belt 3.

[0026] If double-sided polishing is required, the thin plate can be flipped over and then polished again using a thin plate grinding and rust removal device.

[0027] After this step, it was verified that the surface roughness of the thin plate workpiece changed from the factory condition to 20μm ~ 35μm, meeting the requirements of St3.

[0028] By adjusting the direction of the magnetic wheel 1 and the polishing wheel 5, the conveying direction of the conveyor belt 3 can be adjusted, thus adjusting the direction of the production line without moving the device. Adjusting the height of the polishing wheel 5 can accommodate thin plate workpieces of different thicknesses. By replacing the polishing wheel with a different surface grit size, or by adjusting the working state and rotation speed of the magnetic wheel 1 and / or the polishing wheel 5, it is possible to accommodate thin plate workpieces of different thicknesses and polishing requirements. Those skilled in the art will readily understand that the above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
