Abstract
The Laser Welding method of a kind of hydraulic jack post surface laser cladding corrosion resistant plate alive, it is therefore an objective to simple and practical, low cost, pollute few；Thin Stainless Steel coiled sheet is first lived on post by the inventive method at oil cylinder, is welded by butt-welded side seam with argon arc welding, and polishes smooth；Again by post clamping alive for oil cylinder on the slew gear of digital control laser surface processing equipment, the corrosion resistant plate lived volume on post at oil cylinder carries out laser boxing；Until the whole cladding of corrosion resistant plate is on oil cylinder post surface alive；Then with the post surface forming alive of oil cylinder after lathe finish turning cladding；Again with cylindrical grinder grinding oil cylinder post surface alive to the most required size, roughness reaches 0.4 μm.
Description
Technical field
The present invention relates to the thin stainless steel laser deposition of the surface process of hydraulic jack post alive, specifically one on post of living
Replace original electroplating surface and the processing method of powder laser deposition.
Background technology
Along with China's coal-mine production technique development, coal machine equipment develops to heavy-duty, and hydraulic jack is hydraulic support
On important component part, post that oil cylinder is lived is mainly to be processed by chrome-faced and ensures its wear-resisting, corrosion resistance, along with me
State's enhancing to environmental protection consciousness, the cost that chrome-faced processes dramatically increases, and chromium coating is at mine rugged environment
Under easily occur coating come off and get rusty, the situation such as wear no resistance, have producer's powder laser deposition at present and replace at chromium plating
Reason, but the cost of powder deposition is the highest, and be suitable only for part post alive reprocesses processing.
Summary of the invention
The present invention seeks to overcome the deficiency of above-mentioned prior art, it is provided that a kind of durable, low cost simple and convenient, practical,
Pollute the Laser Welding method of few hydraulic jack post surface laser cladding corrosion resistant plate alive.
The inventive method is:
(1) being lived on post at oil cylinder by 0.6～1mm thick Thin Stainless Steel coiled sheet, butt-welded side seam controls within 1mm；Use argon arc welding
Being welded by butt-welded side seam, the weldering height of argon arc welding controls, 1.5～2mm, to polish smooth；
(2) volume, on the slew gear of digital control laser surface processing equipment, is lived on post not at oil cylinder by post clamping of being lived by oil cylinder
Rust steel sheet carries out laser boxing；Spot diameter is 3mm*3mm, to ensure the coverage rate of 50%；Oil cylinder post every revolution alive, swashs
Light welding gun moves 1.5mm；Until the whole cladding of stainless sheet steel is on oil cylinder post surface alive；
(3) with the post surface forming alive of oil cylinder after lathe finish turning cladding；Live post surface to required again with cylindrical grinder grinding oil cylinder
Size, roughness reaches 0.4 μm.
Described stainless sheet steel material is 304 rustless steels.Described digital control laser surface processing equipment model is
JKR3060-25, after finish turning cladding, lathe model used by oil cylinder post surface alive is CA6140.
The inventive method processes the least to the pollution of environment compared to chromium plating, the healthy fanout free region to operating personnel；With powder
End laser cladding processes to be compared, and low cost is a lot, pollutes also few.Through on probation, the hydraulic jack post alive after process is wear-resisting, corrosion-resistant
Property good, be fully able to meet under mine adverse circumstances use requirement；The method can also amplify other needs surface to process
In cylindrical workpiece.
Detailed description of the invention
As a example by post lived by the oil cylinder of a diameter of φ 61；Oil cylinder column diameter D=61mm alive；Design chromium plating section length L=400mm；
Oil cylinder Huo Zhu chromium plating district is rough turn to 60.4mm, and other size diameter stays 0.6mm surplus；According to polish needs, select 0.8mm thick
304 stainless sheet steels；By stainless sheet steel shearing blanking, blank size is 198*400*0.8mm.Add according to the inventive method
Work:
(1) being rolled by the stainless sheet steel that 0.8mm is thick on rough turn good oil cylinder post alive, butt-welded side seam controls within 1mm, volume
Require after having made that external diameter is 62 ± 0.2mm；Seam after spooling with argon arc welding welds, and weldering fracture height control, at 1.5 ~ 2mm, uses angle
Grinding machine is smooth by weld grinding；
(2) volume, on the slew gear of digital control laser surface processing equipment, is lived on post not at oil cylinder by post clamping of being lived by oil cylinder
Rust steel sheet carries out laser boxing；In order to ensure the coverage rate of 50%, spot diameter is 3mm*3mm, post every revolution of living, laser
Welding gun moves 1.5mm, until the whole cladding of stainless sheet steel above is on post surface of living；
(3) live after finish turning cladding post surface size 62mm to 61.6mm, and by other size finish turning molding；Grinding with cylindrical grinder
Cutting 61.6mm external diameter to 61-0.096-0.183mm, roughness reaches 0.4 μm.
