Abstract
The invention discloses a method for wrapping and welding an upright column of a hydraulic support provided with an anti-corrosive layer. By using the method, rusting on surfaces of peripheries of a middle cylinder body, a movable column body and a piston rod of the upright column of the hydraulic support can be prevented, and normal running of the hydraulic support is guaranteed. Stainless steel sleeves are fixedly arranged on the surfaces of the peripheries of the middle cylinder body, the movable column body and the piston rod, so that the surfaces of the peripheries of the middle cylinder body, the movable column body and the piston rod of the upright column cannot be corroded by ions such as sulphur, acid and alkali in emulsion in a cylinder, a phenomenon of rusting is avoided, and normal running of the hydraulic support is guaranteed.
Description
Technical field
The present invention relates to comprehensive mechanical coal mining equipment, particularly relate to a kind of parcel welding and install anticorrosive coat hydraulic support column method additional.
Background technology
Hydraulic support is the important component part of fully-mechanized mining equipment.In coal mining production process, in order to realize the control to top board, maintain certain working space, guarantee carrying out smoothly of the installation of workman's person and every operation, must carry out supporting to top board, the supporting performance of hydraulic support is good, intensity is high, advancing velocity is fast, safe, therefore be often used to top board to carry out supporting, hydraulic support is to using highly pressurised liquid as power, the supporting being comprised of Hydraulic Elements and hardware and the equipment of controlroof, can realize support, cut top, move the operations such as frame and moving conveyor.The active force of hydraulic support stand is hydraulic support column, and the outer cylinder body bottom of hydraulic support column is landed in the base needling of hydraulic support, and the cylinder upper port of living is connected with back timber, by the supporting realizing top board of stretching of middle cylinder body and the cylinder of living.Hydraulic support column is the critical component that top board is supported, and the material of middle cylinder body and the cylinder of living is 27SiMn, present stage external peripheral surface mainly adopt chrome-plated process to process, big for environment pollution.Outside, often there is the phenomenon that from chromium coating spot corrosion starts to form gradually large area corrosion in most of outer circumference surface long term exposure in use, causes chromium coating to come off, and resistant to rust ability affects the serviceability of hydraulic support.During one section of all after date overhaul of production and application, need re-start plating to the chromium coating coming off again.To corrosion, seriously cannot repair, can only scrap processing.
Summary of the invention
The object of this invention is to provide a kind of parcel welding and installed anticorrosive coat hydraulic support column method additional, by the middle cylinder body of column and the outer round surface of live cylinder or piston rod, be fixedly mounted with stainless steel sleeve, there is corrosion in the outer round surface that can permanently prevent the middle cylinder body of hydraulic support column and live cylinder or piston rod, assurance hydraulic support is normally worked, and has eliminated the environmental pollution that electroplating technology brings.
The technical solution used in the present invention is as follows:
An anticorrosive coat hydraulic support column method is installed in parcel welding additional, insert stainless steel sleeve on cylinder body and live cylinder and jack piston rod outer surface in hydraulic support column,
The first step adds man-hour at middle cylinder body and live cylinder or piston rod outer circumference surface, and its external peripheral surface has certain roughness;
After second step machined completes, cylinder body is packed into jacket machine, the a pair of jacket mould that utilizes jacket machine is wrapped on the outer circular shaft of cylinder body stainless steel plate integral is disposable, there is certain angle in the relative cylinder body of a pair of jacket mould axis, with this, guarantee in the process of jacket first to be contacted by the end mouth middle shaft part of cylinder body, then by bottom progressive whole stainless steel sleeve is wrapped on the outer circumference surface of cylinder body closely that make progress, in coated process, by jacket mould, stainless steel sleeve being applied to certain compression makes stainless steel sleeve docile and obedient on matrix closely, and make stainless steel sleeve produce micro-distortion and extension, allowing part material be extended in the knife mark on body connects to form more firmly.After being covered to complete, need docking port to weld, both sides mouth and cylinder body are welded together, just regracting jacket mould after having welded, produces cylinder body;
After producing, the 3rd step again stainless steel sleeve upper and lower port and cylinder body are carried out to boxing;
The weld seam of the 4th step after to boxing carries out grinding so that face of weld is smooth with grinding machine, is of the required size.
Describedly on middle cylinder body and live cylinder or piston rod outer circumference surface, at interval of the distance of 200-300mm, process some cannelures.
Compared with the prior art, beneficial effect of the present invention is as follows:
The method that the present invention welds undergauge fixedly mounts stainless steel sleeve on the outer circumference surface of middle cylinder body, live cylinder or piston rod, replaces the technique of former chromium plating, has eliminated the pollution of chromium plating to environment, compares the molten arc technology of stainless steel laser, and production efficiency is higher.When hydraulic support column is used, the outer circumference surface of stainless steel sleeve can not be corroded, thereby avoids occurring corrosion phenomena, and assurance hydraulic support is normally worked, simplify the flow process of hydraulic support overhaul, and can extend the service life of three times to five times of hydraulic support columns.
Below in conjunction with accompanying drawing, the invention will be further described.
Accompanying drawing explanation
Fig. 1 is that in hydraulic support column, cylinder body is loaded onto stainless steel sleeve structural representation;
Fig. 2 is Fig. 3 A portion structure for amplifying schematic diagram.
The specific embodiment
Referring to accompanying drawing, anticorrosive coat hydraulic support column method is installed in a kind of parcel welding additional, insert stainless steel sleeve on cylinder body and live cylinder and jack piston rod outer surface in hydraulic support column,
The first step adds man-hour at middle cylinder body and live cylinder or piston rod outer circumference surface, and its external peripheral surface has certain roughness;
After completing, second step machined packs cylinder body 1 into jacket machine, utilize a pair of jacket mould 2 being wrapped on the outer circular shaft of cylinder body corrosion resistant plate 3 overall times of jacket machine, there is certain angle in the relative cylinder body of a pair of jacket mould axis, with this, guarantee in the process of jacket first to be contacted by the end mouth middle shaft part of cylinder body, then by bottom progressive whole stainless steel sleeve is wrapped on the outer circumference surface of cylinder body closely that make progress, in coated process, by jacket mould, stainless steel sleeve being applied to certain compression makes stainless steel sleeve docile and obedient on matrix closely, and make stainless steel sleeve produce micro-distortion and extension, allowing part material be extended in the knife mark on body connects to form more firmly.After being covered to complete, need docking port to weld, both sides mouth and cylinder body are welded together, just regracting jacket mould after having welded, produces cylinder body;
After producing, the 3rd step again stainless steel sleeve upper and lower port and cylinder body are carried out to boxing;
The weld seam of the 4th step after to boxing carries out grinding so that face of weld is smooth with grinding machine, is of the required size.
Describedly on middle cylinder body and live cylinder or piston rod outer circumference surface, at interval of the distance of 200-300mm, process some cannelures.
