Abstract
The utility model discloses a novel support vertical column with an anti-corrosive surface, which mainly comprises an outer cylinder body, a middle cylinder body and a movable column; stainless steel sleeves with the thicknesses of 0.6mm to 4.5mm are assembled on the cylinder tube inner hole seal auxiliary surface of the outer cylinder body, the outer surface and the inner hole seal auxiliary surface of the middle cylinder body and the outer surface of the movable column; and the stainless steel sleeves are provided with anti-corrosive layers. Compared with traditional hydraulic supports with electroplated corrosive layers, the anti-corrosive performance of the novel support vertical column with the anti-corrosive surface is improved by more than five times, that anti-corrosive layer is smooth, compact, does not fall off and does not have any pore, the corrosion resistant, anti-aging and wear resistant performance are greatly improved, so that a matched surface has better matching performance, and the phenomena that the surface cracks, falls off and the like are avoided.
Description
Technical field
The utility model relates to mine hydraulic bracket, relates in particular to the column of hydraulic support, is applicable to coal mine fully-mechanized mining or blast mining face hydraulic support stand.
Background technology
Hydraulic support column is the critical piece that hydraulic support is realized lifting, carrying.Abominable because of working condition under the mine, air humidity is big, and mine water is acid, alkaline solution, easily make hydraulic support column work fitting face produce electrochemical corrosion, and influence its sealing performance, cause leakage, do not reach working pressure, the emulsion that spills can cause the pollution to underground water resource.Therefore, generally want the work fitting face of column to carry out preservative treatment.Present processing method is, the middle cylinder body of hydraulic support column (or machinery adds the long-term job post), the outer surface of column of living adopt to be electroplated milky white chromium earlier and feels secure behind the thick 0.02-0.03mm again that hard chrome plating to coating gross thickness is that piece surfaces such as 0.05-0.07mm, extension bar are electroplated 0.008-0.015mm thickness zinc as the anticorrosion antiwear layer, improving its anticorrosive, wear-resisting wiping and the anti-ability of pounding of bumping, and improve the sealing performance of product.Its chromium coating decay resistance warp can reach 300 hours by the ASTMB117 standard detection, but anticorrosion ability is general.After process modification, and its each cylinder inner bore surface also adopted electroplate earlier milky white chromium and feel secure behind the thick 0.015-0.025mm again that hard chrome plating to coating gross thickness is that piece surfaces such as 0.04-0.06mm, extension bar are electroplated 0.008-0.015mm thickness admiro layers as the anticorrosion antiwear layer, its corrosion resistance can reach 600-800 hour, and its Corrosion Protection further improves.But its surface anticorrosion Wear-resistant Treatment technology all is to utilize to electroplate basic surface and corrosive medium are isolated to reach the coating type antisepsis that is not corroded substantially, all is to adopt the electroplating technology process manufacturing of oil removing → rust cleaning → cleaning → surface active → cleaning → plating → cleaning → coating inspection → passivation → recovery → cleaning → coating inspection → warehouse-in to form.Electroplate anticorrosive coat and all have following shortcoming: it is serious that (1) electroplates environment pollution, is unfavorable for operative employee's physical and mental health; (2) there is hydrogen embrittlement, influences the comprehensive mechanical performance of matrix; (3) there is hole in coating, and anticorrosion surface at first the erosion point occurs along it, makes matrix pit occur, causes the coating flaking, further accelerates the matrix corrosion degree, influences the product hermeticity energy.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of electroplating anticorrosive coat, and a kind of new type hydraulic bearer column is provided.
A kind of new type hydraulic bearer column, mainly form by outer cylinder body, middle cylinder body and the post of living, it is characterized in that, the external surface of the external surface of the cylinder barrel endoporus sealing pair surface of outer cylinder body, middle cylinder body and endoporus sealing pair surface and the post of living is equipped with the stainless steel sleeve that thickness is 0.6-4.5mm, and stainless steel sleeve forms anticorrosive coat.
The process of hydraulic support column assembling stainless steel sleeve is:
The first step: with the bore area of outer cylinder body and middle cylinder body respectively boring be machined to preliminary dimension, on the cylinder mouth, process cylinder mouth groove and 20.Cylinder mouth chamfer.The bore area of being close to outer cylinder body and middle cylinder body is fitted into the thick stainless steel sleeve pipe of 0.6-4.5mm, and crimping location, then cylinder body is assemblied in boring machine and places fixing tightly the holding of frock to carry out roll extrusion to the preliminary dimension precision, revise the cylinder mouth after the roll extrusion again, make the cylinder mouth become 20 ° of chamfers, with acetone cleaning cylinder mouth and near zone thereof, with argon arc welding stainless steel sleeve edge mouth and inboard wall of cylinder block are combined together again; Adopt the emulsion that contains the good concentration about 5% of oil emulsion quality as the cooling and lubricating medium when requiring roll extrusion, rolling surface speed is controlled at 1m/min;
Second step: with middle cylinder body and live the post outer round surface respectively the finish turning polishing be machined to preliminary dimension, closely coat the thick stainless steel sleeve of one deck 0.6-4.5mm at the middle cylinder body and the post outer round surface of living then, adopt argon arc welding and cylinder body to form one,, make cylinder body and live the wear-resisting stainless steel layer of post cylindrical top layer formation corrosion to technical requirements size and required precision through continuous machine finishing.
Above-mentioned stainless steel material is selected austenitic stainless steel for use; For example contain chromium greater than 18%, contain the austenitic stainless steel of elements such as nickel about 8% and a small amount of molybdenum, titanium.
The utility model has the advantages that: compare with the hydraulic support column of the plating anticorrosive coat of present application, its anticorrosive property improves more than five times, anticorrosive coat is smooth, fine and close, nothing is peeled off, the imporosity, greatly improve corrosion-resistant, the anti-aging and anti-wear performance of workpiece, make that be mated mask has better matching property, phenomenon such as stopped surperficial generation fracture or peel off; And owing to the oxygen effect in chromium element in the stainless steel layer and the corrosive medium, form the very thin oxide film (self-passivation film) of one deck, can stop the matrix of steel further to corrode, make it have lasting Corrosion Protection on the steel surface; Make that its sealing performance is superior, functional reliability further improves; Can water or underground water be working media, realize the nonhazardous, pollution-free in column production and the use; Relative price is low, and maintenance cost is low, long service life, and, meet the excellent surface course of environmental protection growth requirement and availability because of its unique technique technology, product has the very strong market competitiveness and popularizing application prospect.
