Problems solved by technology

In the prior art, automatic grinding processes and devices are often used in the grinding of non-metallic structural parts, while the grinding of metal structural parts, especially rail vehicle bogies, is done by manually holding manual grinding tools, including profiling grinding. Work, the disadvantage of manual grinding is low work efficiency and low grinding quality and precision

Embodiment 1

[0053] (1) A rust-removing and polishing method for a copper target assembly, the rust-removing and polishing method comprises: using a polishing medium to sequentially perform rust surface polishing and texture polishing on the rust surface of the copper target assembly; The surface roughness Ra≤0.8μm; the texture grinding starts from the center point of the rusted surface.

[0054] (2) The sanding medium includes velvet sandpaper and scouring pad.

[0055] (3) The rust surface is polished by using back velvet sandpaper.

[0056] (4) The texture polishing is performed by using a scouring pad.

[0057] (5) Before the sanding treatment, masking treatment is performed on the non-grinding surface.

[0058] (6) The masking treatment is to mask the non-polished surface with an adhesive tape.

[0059] (7) The backing plate in the target assembly should be placed on the fixture before grinding.

[0060] (8) A cleaning cloth is arranged between the back plate and the fixture.

Embodiment 2

[0064] (1) A method for grinding the weld seam of a cold-rolled stainless steel welded pipe. The grinding method is to use a grinding wheel whose sand density on the grinding surface gradually increases in the advancing direction of the weld seam to grind the weld seam in three steps. The grinding wheel used in the third grinding process in the advancing direction is at an angle of 10-15 degrees with the advancing direction of the weld; the grinding wheels used in the first two grinding processes in the three processes are 180 in turn. Grinding wheel and No. 180 grinding wheel, the grinding wheel used in the third grinding process is No. 320 grinding wheel.

[0065] (2) The grinding wheel used in the first two grinding processes in the advancing direction of the welding seam is at an angle of 45 degrees with the advancing direction of the welding seam, and the grinding wheel used in the first two grinding processes is advancing with the welding seam. The 45-degree angle formed...

Embodiment 3

[0067] (1) A method for grinding the weld seam of a cold-rolled stainless steel welded pipe. The grinding method is to use a grinding wheel whose sand density on the grinding surface gradually increases in the advancing direction of the weld seam to grind the weld seam in three steps. The grinding wheel used in the third grinding process in the advancing direction is at an angle of 10-15 degrees to the advancing direction of the weld.

[0068] (2) The grinding wheel used in the first two grinding processes in the advancing direction of the welding seam is at an angle of 45 degrees with the advancing direction of the welding seam, and the grinding wheel used in the first two grinding processes is advancing with the welding seam. The 45-degree angle formed between the directions is alternately distributed with different yaw directions.

[0069] (3) The grinding wheels used in the first two grinding processes are No. 180 grinding wheels, No. 180 grinding wheels and No. 180 grindi...

Abstract

The invention discloses a polishing method for treating roughness and smoothness of a metal structural surface. The polishing method comprises the following steps that firstly, a workpiece is placed, specifically, the workpiece needing to be polished is placed on a conveying device, the workpiece is carried through the conveying device, the workpiece is moved to a designated position, and the workpiece is machined; secondly, roughness is detected, and the roughness of the metal surface needing to be machined is detected through a metal roughness detector; and thirdly, the workpiece is conveyed to a grinding area through the conveying device, the two sides of the workpiece are clamped through a limiting device and a clamping structure, and the workpiece is prevented from shaking in the grinding process. According to the roughness detection device is arranged, the surface of the workpiece is checked before grinding, the position of the surface roughness is confirmed, the grinding device can conveniently grind the position which does not meet the specification, the grinding speed is increased, the grinding quality is improved, then the surface of the workpiece is checked again after machining is completed, and whether polishing meets the specified requirements is determined.

Description

technical field [0001] The invention relates to the technical field of metal structure surface processing, in particular to a grinding method for processing the roughness and smoothness of a metal structure surface. Background technique [0002] Metal surface grinding is to grind the surface of the metal. After the metal workpiece is produced, there will be many burrs, and there are many places on the surface that do not meet the regulations. It is necessary to reshape the surface of the metal by grinding to improve the quality of the metal. The workpiece is processed into parts that meet the requirements of the workpiece to ensure the quality of processing. [0003] The defects that exist in the grinding method in the prior art are: [0004] 1. The reference document CN105583703A discloses a method for grinding a welded seam of a cold-rolled stainless steel welded pipe. "The grinding method is to use a grinding wheel whose sand density on the grinding surface gradually inc...
