Description
Technical field
The present invention relates to production facility of coalmine technical fields, more particularly to a kind of column middle cylinder for coal mine bracket
Laser melting coating processing technology.
Background technique
In coal production, underground work often faces the danger of roof fall cave-in accident, and support of mines operation is for safety
Production has extremely important effect.
As the main load-carrying unit of bracket, the service life of bracket upright post directly affects the service life of bracket, column middle cylinder
Coating area is more more wear resistant than traditional chromium plating, anti-corrosion, heat-resisting and anti-oxidant using laser melting coating, to increase the service life of column.
And laser melting coating is placed in last procedure by common processing technology, will lead to middle cylinder bore in this way molten
It is deformed at a high temperature of covering, generates the adverse effect of inner hole contraction distortion etc..
Summary of the invention
In view of the deficiencies in the prior art and insufficient, the purpose of the present invention is to provide a kind of bracket upright post middle cylinders
Laser melting coating processing technology.
Technical scheme is as follows:
A kind of cladding processing technology of bracket upright post middle cylinder, it is characterised in that the laser melting coating of the bracket upright post middle cylinder
Processing technology is successively the following steps are included: (1) blanking；(2) it is heat-treated；(3) surface derusting；(4) vehicle coating outer circle；(5) laser
Cladding；(6) interior hole machined；(7) vehicle cylinder mouth；(8) cylinder bottom is welded；(9) the non-coating outer circle of smart car；(10) coating outer circle is refined.
Further technical solution includes that step (3) surface derusting is shot peening technique.
Further technical solution includes that step (6) interior hole machined is the following steps are included: (61) vehicle chamfering；(62) it slightly pushes away
Boring inner hole；(63) ageing treatment；(64) chamfering is repaired；(65) essence pushes away boring inner hole；(66) roll forming.
Further technical solution includes that in step (5) laser melting coating, there are machining allowance for coating after cladding.
Further technical solution includes that step (7) vehicle cylinder mouth is finish turning cylinder mouth.
Further technical solution includes that step (1) blanking is sawing machine blanking.
The technical effects of the invention are that:
The present invention is adjusted by the processing technology to existing bracket upright post middle cylinder, and in prior art, laser is molten
The influence that process centralizing cylinder inner hole causes contraction distortion is covered, middle cylinder working life and stable and reliable operation have been seriously affected, is led to
Adjustment process flow is crossed, after finishing of internal diameter is set to cladding process, avoids major defect existing in the prior art
And deficiency.
In order to guarantee the smooth implementation of laser melting coating process, the turning of coating area outer circle is provided with before laser melting coating
The cylinder body outer circle region that laser melting and coating process will be implemented is carried out turning processing, ensure that the region according to sharp by manufacturing procedure
The structure snd size that light melting and coating process implementation specification requires, in order to which subsequent laser melting coating process is smoothly implemented.
After the completion of laser melting coating process, it is additionally provided with and precision grinding process is implemented to the laser melting coating coating, improve and guarantee
The fit dimension of the cladding region and the requirement of precision, further increase the working life and operation stability of middle cylinder component.
Specific embodiment
The present invention will be further described below.
In the processing technology of existing bracket upright post middle cylinder, laser melting coating process is often set to after inner hole pushes away boring, band
Carry out middle cylinder bore to be deformed or shrink at a high temperature of laser melting coating, influences assembly precision and quality.
Bracket upright post middle cylinder laser melting coating processing technology of the invention includes following below scheme: (1) blanking；(2) it is heat-treated；
(3) surface derusting；(4) vehicle coating outer circle；(5) laser melting coating；(6) interior hole machined；(7) vehicle cylinder mouth；(8) cylinder bottom is welded；(9)
The non-coating outer circle of smart car；(10) coating outer circle is refined.
Wherein, surface derusting is shot peening technique.
Interior hole machined includes following process: vehicle chamfering；Slightly push away boring inner hole；Ageing treatment；Repair chamfering；Essence pushes away boring inner hole；Rolling
It is molded.
In laser melting coating, there are subsequent machining surpluses for coating after cladding.
Vehicle cylinder mouth is finish turning cylinder mouth.
Blanking is sawing machine blanking.
Processing technology of the invention retains more than subsequent processing by first implementing laser melting and coating process, and in cladding region
Then amount pushes away boring processing by inner hole and laser melting coating cladding region implements precision grinding process, improves and ensure that the coating
The fit dimension in region and the requirement of precision further increase the working life and operation stability of middle cylinder component.
The above is the preferred embodiment of the present invention, for a person skilled in the art, public according to the present invention
The technology contents and essence opened can also make other modification and improvement, but these do not depart from technical spirit of the invention
Modification and improvement will fall into protection scope of the present invention.
