And good concentricity, appearance are bright, inner hole is smooth, geometric tolerance guarantees in 0.01-0.02mm.
Currently, being directed to the polishing on slender rectangular tube surface, most of processing enterprises all take the mode of pickling, can reach
The requirement of surface roughness and surface topography.But chemical polishing pollutes the environment, and chemical reagent has injury to human body, because
This this kind of technology cannot function as precision machined main flow direction.
In recent years, abrasive grain Flow Technique is gradually applied to the processing of slender rectangular tube inner surface, and principle is to pass through pushed at high pressure
Fluid moves in pipe, and fluid is to the continuous Ground shock waves in surface.But the processing efficiency of current this method is relatively low, and slender rectangular tube
The quality of surface polishing is lower.
Summary of the invention
In order to make up for the deficiencies of the prior art, a kind of long and thin metal pipe fitting technique for grinding proposed by the present invention, master of the present invention
It is used to solve that existing pipe fitting technique for grinding to be poor to the grinding accuracy of long and thin metal pipe fitting, the efficiency of long and thin metal pipe fitting polishing
Lower problem.
The technical solution adopted by the present invention to solve the technical problems is: a kind of long and thin metal pipe fitting of the present invention is beaten
Grinding process, the technique include the following steps:
S1: long and thin metal pipe fitting is passed through into grinding apparatus manually, and long and thin metal pipe fitting is placed into grinding apparatus lower end
Between two idler wheels；It is placed on idler wheel by the way that long and thin metal pipe fitting is passed through grinding apparatus, passes through the relative rotation band of idler wheel
Dynamic long and thin metal pipe fitting is mobile, polishes, and guarantees the continuity of pipe fitting polishing, improves grinding efficiency；It is beaten by using this
Mill equipment effectively improves the grinding effect of metal tube, improves the quality of long and thin metal pipe fitting surface polishing；
S2: abrasive grain is filled by feed pipe in the elastic metallic string bag into S1 in grinding apparatus, abrasive grain is through elasticity
Mesh on metal net bag polishes to long and thin metal pipe fitting；By the way that long and thin metal pipe fitting is passed through in the middle part of the elastic metallic string bag
Channel after place into abrasive grain, avoid long and thin metal pipe fitting that from can not causing to reduce thin by the channel in the middle part of the elastic metallic string bag
The efficiency of long metal pipe part polishing work；Meanwhile it being generated in long and thin metal pipe fitting moving process with abrasive grain and the elastic metallic string bag
Friction, so that abrasive grain does not stop to roll when polishing long and thin metal pipe fitting, to guarantee that abrasive grain acts on long and thin metal pipe fitting surface
Effect, and then improve abrasive grain polishing long and thin metal pipe fitting quality；Also, the elastic metallic string bag can generate shake, to change
The position that the abrasive grain become on the elastic metallic string bag is contacted with long and thin metal pipe fitting, so that it is more complete to polish long and thin metal pipe fitting
Face, and then improve the quality of long and thin metal pipe fitting polishing；
Size reduces after abrasive wear in S3:S2, and abrasive grain leaks out from mesh and drops down onto the next layer of elastic metallic string bag
It is interior；It is gradually reduced in the grinding process by grit size, so that abrasive grain is constantly fallen into the next layer of elastic metallic string bag, and
The size of abrasive grain constantly reduces, and the precision that abrasive grain polishes to long and thin metal pipe fitting is gradually increased, so that with long and thin metal
The size of the movement of pipe fitting, abrasive grain can automatically update, to reduce the step of finishing again, improve the effect of work
Rate also ensures the quality of long and thin metal pipe fitting polishing；
Abrasive grain in S4:S3 is finally leaked out out of undermost the elastic metallic string bag, and grinding apparatus is discharged and is recycled,
Long and thin metal pipe fitting is persistently polished；Long and thin metal pipe fitting constantly enters, and polishing work constantly carries out, and abrasive grain is taken away when being discharged

As shown in Figures 2 and 3,5 both ends of channel in the elastic metallic string bag 4 are provided with chamfering structure；When work, lead to
5 both ends of road are set as chamfering structure and pass through convenient for pipe fitting 3, also, when pipe fitting 3 moves down so that channel 5 just with pipe fitting
3 is tangent, passes through channel convenient for pipe fitting 3, while abrasive grain 6, under frictional force drive, the abrasive grain 6 in chamfering is close to pipe fitting 3, in turn
Automatic 6 quantity of abrasive grain for increasing contact improves the quality of the polishing pipe fitting 3 of abrasive grain 6.
Specific workflow is as follows:
When work, pipe fitting 3 is sequentially passed through into inlet port and outlet port manually, pipe fitting 3 is set between two idler wheels 2,
Pipe fitting 3 is set not stop to move by the rotation of idler wheel 2；Abrasive grain 6 is passed through into the elastic metallic string bag 4 by feed pipe, abrasive grain 6 is saturating
The mesh crossed on the elastic metallic string bag 4 polishes to pipe fitting 3, as movement and the abrasive grain 6 of pipe fitting 3 rub, abrasive grain 6
Size reduces, and abrasive grain 6 is rolled during rubbing with pipe fitting 3, improves the effect of the polishing pipe fitting 3 of abrasive grain 6, improves
The quality of 3 surface of pipe fitting polishing；Meanwhile with the movement of pipe fitting 3, the friction of pipe fitting 3 and abrasive grain 6 drives the elastic metallic string bag 4
It is shaken, changes abrasive grain 6 and pipe fitting 3 acts on the position on pipe fitting 3, to improve the effect of 3 surface of pipe fitting polishing；Elasticity
The shake of metal net bag 4 shakes abrasive grain 6, and 6 size of abrasive grain after abrasion reduces, when abrasive grain 6 is leaked out from mesh, subsequent mill
Grain 6 is added in mesh, and the progress for keeping the polishing operation duration of pipe fitting 3 stable improves the quality of 3 surface of pipe fitting polishing；Size
Reduced abrasive grain 6 falls into the next layer of elastic metallic string bag 4, continues to polish to pipe fitting 3, since 6 size of abrasive grain constantly reduces,
So that the polishing of 3 surface of pipe fitting is more fine, the quality of 3 surface of pipe fitting polishing is further improved, simultaneously as having set at least
Three layers of the elastic metallic string bag 4, when abrasive grain 6, which constantly becomes smaller, falls into next layer, so that 6 size of abrasive grain automatically updates, with
The movement of pipe fitting 3 reduces subsequent the step of finishing again, improves so that the precision of 3 surface of pipe fitting polishing is gradually increased
Working efficiency, reduces labor intensity；The abrasive grain finally fallen exports discharge recycling from abrasive grain by inclined marker board 7.
