Abstract
The invention discloses a kind of hot-rolled stainless steel welded pipe weld grinding method, the polishing process is the polishing for carrying out four procedures to weld seam using the grinding wheel that gradually steps up of grains of sand density of buffed surface in weld seam direction of advance, and the grinding wheel used in the 4th polishing operation and weld seam direction of advance in weld seam direction of advance are in 10 15 degree of angles.The hot-rolled stainless steel welded pipe weld grinding method of the present invention can make the smoothness requirements that stainless steel welding tube can reach 600 degree after by follow-up surface polish line processing, substantially increase the finish of stainless steel welded pipe surface.
Description
Technical field
The present invention relates to a kind of polishing process, more particularly to a kind of hot-rolled stainless steel welded pipe weld grinding method.
Background technology
The difficult point of stainless steel welded pipe surface polishing is extremely difficult to the requirement of best bright finish just in the processing to soldered,
Therefore, the surface smoothness of traditional stainless steel welding tube is not very high.With a large amount of uses of decoration tubing, to stainless steel welded
The outer surface of pipe requires more and more higher, it is therefore necessary to invents a kind of hot-rolled stainless steel welded pipe weld grinding method.
The content of the invention
It is an object of the invention to provide a kind of hot-rolled stainless steel welded pipe weld grinding method, stainless steel welding tube can be made to exist
By can reach 600 degree of smoothness requirements after follow-up surface polish line processing, stainless steel welded pipe surface is substantially increased
Finish.
To achieve the above object, the present invention provides a kind of hot-rolled stainless steel welded pipe weld grinding method, the polishing process
It is to carry out four procedures to weld seam using the grinding wheel that the grains of sand density of buffed surface gradually steps up in weld seam direction of advance to beat
Mill, the grinding wheel used in the 4th polishing operation in weld seam direction of advance are pressed from both sides with weld seam direction of advance in 10-15 degree
Angle.
As a further improvement on the present invention, the polishing used in first three road polishing operation in weld seam direction of advance
Wheel and weld seam direction of advance be in 45 degree of angles, grinding wheel and weld seam direction of advance used in first three described road polishing operation
Between 45 degree of angles forming be alternately distributed with different beat directions.
As the further improvement of the present invention, grinding wheel used in first three described road polishing operation is followed successively by 100
Number grinding wheel, No. 100 grinding wheels and No. 180 grinding wheels, grinding wheel used in the 4th polishing operation is No. 320 grinding wheels.
Compared with prior art, hot-rolled stainless steel welded pipe weld grinding method of the invention has the beneficial effect that：
(1) the 4th procedure uses the grinding wheel in 10-15 degree angles with weld seam direction of advance, and beating in four procedures
The grains of sand density of the buffed surface of emery wheel gradually steps up in weld seam direction of advance so that the stainless steel welding tube after processing is passing through
After follow-up surface polish line processing, 600 degree of surface smoothnesses can be reached, substantially increase the light of stainless steel welded pipe surface
Cleanliness.
(2) be alternately distributed in the grinding wheels of 45 degree angles with different beat directions, and use 100, No. 100,180
Number, the grinding wheel of No. 320, the surface smoothness that can be further ensured that in follow-up polishing process.
It will be become more fully apparent by following description and with reference to accompanying drawing, the present invention, these accompanying drawings are used to explain the present invention
Embodiment.
Brief description of the drawings
Fig. 1 is hot-rolled stainless steel welded pipe weld grinding schematic diagram.
Embodiment
Embodiments of the invention are described with reference now to accompanying drawing, similar element numbers represent similar element in accompanying drawing.
Fig. 1 is refer to, described hot-rolled stainless steel welded pipe weld grinding method is to use to beat in weld seam a directions of advance
The grinding wheel b that the grains of sand density of flour milling gradually steps up to weld seam carry out four procedures polishing, in weld seam a directions of advance before
Grinding wheel b used in three polishing operations and weld seam direction of advance are in 45 degree of angles, used in the 4th polishing operation
Grinding wheel b and weld seam a directions of advance be in 10-15 degree angles.Grinding wheel b used in first three described road polishing operation with
The 45 degree of angles formed between weld seam a directions of advance are alternatively distributed with different beat directions.Described first three road polishing work
Grinding wheel b used in sequence is followed successively by No. 100 grinding wheels, No. 100 grinding wheels and No. 180 grinding wheels, the 4th polishing operation institute
The grinding wheel b used is No. 320 grinding wheels.Using it is foregoing be in 45 degree and 10-15 degree angles grinding wheel b be processed after not
Rust steel welded pipe, after by follow-up surface polish line processing, 600 degree of surface smoothnesses can be reached, substantially increased not
The finish for steel welding pipe surface of becoming rusty.
Above in association with most preferred embodiment, invention has been described, but the invention is not limited in implementation disclosed above
Example, and modification, equivalent combinations that the various essence according to the present invention are carried out should be covered.
