Description
Technical field
The present invention relates to a kind of method of profile shapes shotblasting, belong to field of machining.
Background technology
Impeller head carries out impeller blasting using High-velocity Projectiles a fluid stream to the outer wall of rotation, remove section bar outer surface oxide layer with
Attachment, is allowed to obtain the clean surface of uniform, fine, appears steel pipe matrix color.
Roller-way is the tactic pattern that V-type roller-way continuous conveying is rotationally advancing automatically, main to utilize impeller head High-velocity Projectiles stream
Outer weekly form in rotary moving is thrown in beam continuum, produced kinetic energy is smashed and descaling and its attachment, makes steel pipe
Appearance is shown in the effect of mother metal, and reaches finished surface finish and finished product cleaning index.
The content of the invention
The present invention is intended to provide a kind of method of profile shapes shotblasting, by changing impeller head internal transmission angle, expands
Big projection surface region, uniform perfect ball blast effect is reached for the complicated profile shapes in cross section.Specifically one kind can be improved
The utilization rate of existing equipment, reaches the shot blasting method of cleaning profile shapes surface efficiency, using common shot-blasting machine it is complicated to cross section,
Rotation, the profile shapes advanced removing surface operation can not be carried out on roller-way.
The processing step of profile shapes surface cleaning is：Profile shapes sawing end to end → calculating → welding → barycenter test → plane
Roll test → ball blast → sawing support tube → cleaning.
The invention provides a kind of method of profile shapes shotblasting, including herein below：
（1）Select ball blast：
Shot-blasting machine outer surface processing profile shapes type selecting uses shot, and in round bead shape, good fluidity is conducive to machine interior circulation, added
Man-hour ensure that the surface treatment that high efficiency and high covering are carried out to cast(ing) surface, can cover the defect on workpiece surface.
Shot specification chooses S170, and biggest size of element is 0.5mm.
（2）Design support tube：
Left and right support tube is set respectively at profile shapes two ends, and left and right support tube is symmetrical arranged, and its structure, weight are identical.
Support bore equal with the inscribed circle diameter of profile shapes.
In running, the weight that support tube is born is T1+0.5T；Wherein, T is profile shapes weight, and T1 supports to be unilateral
Pipe weight.
The half of the equal length of left and right support tube, respectively profile shapes length.
Shot-blasting machine roller-way idler roll spacing is the half of support length of tube.
Special section by it is front and rear with before and after welding manner support placement steel pipe it is reached what is advanced on roller-way
Target.Combined in real process with field condition, the special-shaped steel weight of middle part all uniformly increases in front and rear extra cloth
Whether spacing, which can be, in the steel pipe deadweight put, between synchronous consideration roller makes the front and rear steel pipe split advance in roller table surface and will not occur
Plant into situation.Actual weight of the front and rear increased steel pipe among roller-way changes, and weight change is deadweight and profile shapes
The summation of weight 1/2.Selection of dimension is improper, the situation that overload burning will occur for speed reducer of electric machine for roller.It is steel pipe to increase scope
Length be 1 times of profile shapes standard.
（3）Impeller head angle adjustment
Impeller head increases shot by elevator to the flow of fixed-direction to hopper makes it be fluctuated in claimed range, can not surpass
Go out the rated current of impeller head necessary electromotor.Impeller head is within any one unit interval, and ball blast amount is in a datum plane
It can be regarded as a rectangle.There are bumps in profile shapes surface, actual equivalent area exceedes beyond rectangle, to ensure ball blast effect
Really, it is necessary to be the increase of its ball blast coverage rate, surface can be made to have good uniformity.Impeller head common-mode is linear arrangement,
Three are 1 group, and the intersection of physical presence ball blast projection surface is omitted for complete be not present of guarantee coverage rate.
Impeller head is due to linear arrangement, and projection surface is that Horizontal sinusoidal curve distorts coverage mode, and H profile steel has concave surface, is
Ensure the curved surface spreadability of projection surface, the guide sleeve angle of impeller head is adjusted, by tilting 15 degree of position adjustments clockwise to the inverse time
Pin correspondence position, the scope of projection surface expands, and it is completely covered surface.15 degree are accurate location, and going beyond the scope will
Projection surface angle is occurred with horizontal plane, excessive abrasion, shot impact impeller head backplate, nothing are produced to the backplate inside impeller head
Shot is projected profile shapes surface by method.
（4）Welding manner
Support tube disposes aluminium sheet with profile shapes connecting portion；
（5）Barycenter test
Two vertical levels detections are utilized in horizontal plane；
（6）Roll test
Roll 10 meters in horizontal plane by hand, smooth undamped, it is front and rear it is reciprocal twice, 10 minutes every time；
（7）Shot installation amount is 3 tons among operating process, and roller-way power converter output is adjusted to 30 ~ 50%；
（8）Crop end
Using band sawing machine operation, burr is prevented；
（9）Cleaning
15-20min is soaked in pickling, and surface is post-processed.
Beneficial effects of the present invention：
（1）The utilization rate of existing equipment is improved, the shot blasting method of cleaning profile shapes surface efficiency is reached, uses common shot-blasting machine pair
Cross section is complicated, it is impossible to the rotation on roller-way, and the profile shapes of advance carries out removing surface operation.
（2）By changing impeller head internal transmission angle, expand projection surface region, reached for the complicated profile shapes in cross section
To uniform perfect ball blast effect.
（3）Belong to machine industry driven Design, mechanical processing industry, it is adaptable to which H profile steel, T-steel, L-type steel etc. are each
Section bar is planted, can specifically make the profile shapes of special cross-section shape can be rotationally advancing on roller-way, and impeller head can be completely to table
Face is handled.
