Description
Technical field
The invention belongs to sectional material polishing technical field, more particularly, to a kind of aluminium alloy extrusions technique for grinding.
Background technology
Often there are some weld seams in aluminium alloy extrusions, the polishing effect to these weld seams can be straight in process of manufacture
Connect the progress for having influence on next step process, but the technique for grinding of current aluminium alloy extrusions is after polishing aluminium alloy,
The smoothness and flatness of welded seam area are all poor.
The content of the invention
The present invention is for overcome the deficiencies in the prior art, there is provided a kind of aluminium alloy extrusions polishing good to weld grinding effect
Technique.
To achieve these goals, the present invention uses following technical scheme：A kind of aluminium alloy extrusions technique for grinding, including such as
Lower step：
(1) surface is roughly ground：Aluminium alloy extrusions is fixed, and Surface of profile beaten using the angle grinder equipped with emery wheel
Mill, the angle for ensureing emery wheel and Surface of profile during polishing is 10-20 °, until by the oxide layer of Surface of profile all polish off for
Only, the depth of polishing is no more than the 3% of section bar thickness；
(2) weld seam is roughly ground：Using being mounted with direction of the staight shank sander of stainless steel brush along weld seam to the weldering on section bar
Seam is polished；
(3) weld seam fine grinding：Face of weld is polished using the angle grinder equipped with emery wheel, the table of emery wheel is caused during polishing
Face is parallel with face of weld, along bead direction polishing welding seams, until removing weld reinforcement；
(4) splash is polished around weld seam：Make emery wheel using the angle grinder polishing welding seams week region equipped with emery wheel, during polishing
Parallel to Surface of profile, untill the spatter thing for being attached to Surface of profile is polished off；
(5) surface fine grinding：Surface of profile is polished by hand using 600-800# dry sand paper, is polishing to Surface of profile
Untill smooth, smooth.
Surface of profile is roughly ground with angle grinder, the oxide layer of removal Surface of profile that can be faster, and rear profile of polishing
Material surface is more smooth, and emery wheel is kept for 10-20 ° with Surface of profile, and emery wheel relatively quick can produce certain polishing to section bar
Depth, accelerate grinding efficiency；With staight shank sander along bead direction polishing welding seams, the oxygen on weld seam can be quickly polished off
Change layer；With angle grinder along the direction polishing welding seams parallel with Surface of profile, the reinforcement of weld seam can be polished off so that face of weld and
Surface of profile lifts the flatness and smoothness of Surface of profile in sustained height；With angle grinder polishing welding seams peripheral region, and protect
Hold that emery wheel is parallel with Surface of profile, the splash around weld seam can be polished off, ensure the flatness and smoothness of Surface of profile；With
600-800# dry sand paper manual grinding Surface of profile, the flatness and smoothness of Surface of profile are further lifted, is welded after polishing
Seam region has excellent smoothness and flatness.
Further, when with the reinforcements of angle grinder polishing welding seams, the grinding depth to weld seam is 1-2mm every time；Due to
Grinding depth is bigger, and the resistance that emery wheel is subject to is bigger, is more not easy to keep emery wheel parallel with the surface of section bar, and then easily in type
Material surface produces rough polishing scratch, and it is 1-2mm to keep each grinding depth, effectively prevent and is produced in Surface of profile
The situation of uneven polishing scratch occurs.
Further, when being polished with angle grinder Surface of profile, the emery wheel model 320# that is installed in angle grinder,
And first determine whether emery wheel firmly installs before being polished, and when angle grinder rotation 3-5 minutes, observation emery wheel rotation it is whether steady
It is fixed；Select 320# emery wheel, the polishing effect to aluminium alloy section surface is good, polishing before first check emery wheel installation situation and oneself
Turn situation, it is therefore prevented that because emery wheel rotation it is unstable and to section bar caused by larger grinding depth situation occur, reduce to section bar
Damage, also improve the security of operation in addition.
In summary, by the present invention in that being polished with angle grinder and staight shank sander the surface of section bar and weld seam,
The oxide layer and spatter thing of Surface of profile are eliminated, is then carrying out manual grinding with dry sand paper, welded seam area is polished and imitated
Fruit is good, section bar surfacing after polishing, smooth.
