Abstract

The invention discloses a hydraulic support lifting jack provided with stainless steel sleeves and an assembly method for the stainless steel sleeves. The hydraulic support lifting jack mainly comprises a cylinder body and a piston rod, wherein the surface of the inner circle of the cylinder body and the surface of the outer circle of the piston rod are provided with the stainless steel sleeves; the stainless steel sleeves form an anticorrosive coating of a working fitting surface. Compared with the current applied hydraulic support lifting jack with the electroplating anticorrosive coating, the hydraulic support lifting jack improves the anti-corrosive performance by more than five times; the anti-corrosive coating is smooth and compact, is free of striping and holes, greatly improves anti-corrosive, anti-aging and wear-resisting performances of workpieces and leads the workpiece and the fitting surface to have better coordinating performance and puts an end to the breakage or stripping and the like phenomena of surfaces.

Description

The hydraulic support jack and the stainless steel sleeve assembly method of assembling stainless steel sleeve
Technical field
The present invention relates to mine hydraulic bracket, relate in particular to the jack of hydraulic support.
Background technology
The hydraulic support jack is the major part that hydraulic support is realized lifting, carrying, is made up of cylinder body, piston rod, orienting sleeve, interstage sleeve, back-up ring and sealing member.Abominable because of working condition under the mine, air humidity is big, and mine water is acid, alkaline solution, easily make hydraulic support jack work fitting surface produce electrochemical corrosion, and influence its sealing property, cause leakage, the out of reach working pressure, the emulsion that spills can cause the pollution to underground water resource.Therefore, generally to carry out anti-corrosion treatment to the work fitting surface of jack.Present processing method is, the cylinder body internal circular surfaces of hydraulic support jack, piston rod outer round surface adopt to be electroplated milky white chromium earlier and feels secure behind the thick 0.02-0.03mm again that hard chromium plating to coating gross thickness is that 0.05-0.07mm is as the anticorrosion antiwear layer, improving its anticorrosive, wear-resisting wiping and the anti-ability of pounding of bumping, and improve the sealing property of product.Its chromium coating decay resistance is through reaching 600-800 hour by the ASTMB117 standard detection.
Above-mentioned surface anticorrosion Wear-resistant Treatment technology utilization is electroplated basic surface and corrosive medium isolation is not corroded to reach substantially, adopts the electroplating technology process of oil removing → rust cleaning → cleaning → surface active → cleaning → plating → cleaning → coating inspection → passivation → recovery → cleaning → coating inspection → warehouse-in.Electroplate preservative coat and have following shortcoming: it is serious that (1) electroplates environmental 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 objective of the invention is to overcome the shortcoming of electroplating preservative coat, a kind of hydraulic support jack that assembles stainless steel sleeve is provided, and a kind of process of assembling stainless steel sleeve is provided.
A kind of hydraulic support jack that assembles stainless steel sleeve mainly is made up of cylinder body and piston rod, it is characterized in that, the internal circular surfaces of cylinder body and the outer round surface of piston rod are equipped with stainless steel sleeve, the preservative coat of stainless steel sleeve formation work fitting surface.
The process of hydraulic support jack assembling stainless steel sleeve is:
One, with cylinder body internal circular surfaces boring processing to preliminary dimension, on the cylinder mouth, process cylinder mouth groove and 20 ° of cylinder mouth chamfers, being close to inboard wall of cylinder block fit on thickness is the stainless steel sleeve of 0.6-4.5mm, and crimping location, then with the cylinder body 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 oil emulsion concentration about 5% as the cooling and lubricating medium when requiring roll extrusion, the rolling surface speed control is at 1m/min;
Two, the polishing of piston rod outer round surface finish turning is machined to preliminary dimension, closely coats the thick corrosion-resistant steel sleeve-board of one deck 0.6-4.5mm at the piston rod outer round surface then, adopt argon arc welding and piston rod to be welded into one again;
Through the technical size of machine finish to accuracy requirement.
Above-mentioned stainless steel material is selected austenitic stainless steel for use, as contains chromium greater than 18%, and contains elements such as nickel about 8% and a small amount of molybdenum, titanium.
Advantage of the present invention is: compare with the hydraulic support jack of the plating preservative coat of present application, its anticorrosive property improves more than five times, preservative coat is smooth, fine and close, nothing is peeled off, the imporosity, greatly improve workpiece withstanding corrosion, antiageing and wear resisting property, 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 fire coat (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 property is superior, functional reliability further improves; Available water or earthing water are working medium, the nonhazardous in realization production and the use, pollution-free; Relative price is low, and service expenditure is low, long service life, and, meet the excellent superficial layer of environmental protection growth requirement and availability because of its unique technique technology, product has the very strong market competitiveness and popularizing application prospect.
Description of drawings
Fig. 1 is the cross sectional drawing of the embodiment of the invention.
Marginal data: 1-cylinder body; The 2-piston rod; 3,4-stainless steel sleeve.
The specific embodiment
As shown in Figure 1, a kind of hydraulic support jack that assembles stainless steel sleeve is made up of cylinder body 1 and piston rod 2, it is characterized in that, the internal circular surfaces of cylinder body 1 is equipped with stainless steel sleeve 3, and the outer round surface of piston rod 2 is equipped with stainless steel sleeve 4, and stainless steel sleeve 3 and 4 forms the preservative coat of work fitting surface.
The process of hydraulic support jack assembling stainless steel sleeve is:
One, with cylinder body 1 internal circular surfaces boring processing to preliminary dimension, at cylinder mouth get on the bus out cylinder mouth groove and 20 ° of cylinder mouth chamfers, being close to cylinder body 1 inwall fit on thickness is the stainless steel sleeve 3 of 0.6-4.5mm, and crimping location, then cylinder body 1 is assemblied in boring machine and places frock to fix and tightly hold, carry out roll extrusion, roll extrusion is to the preliminary dimension precision; During roll extrusion, adopt the emulsion that contains oil emulsion concentration about 5% as the cooling and lubricating medium, the rolling surface speed control is at 1m/min; Revise the cylinder mouth after the roll extrusion, make the cylinder mouth become 20 ° of chamfers, and, with argon arc welding stainless steel sleeve 3 edge mouths and cylinder body 1 inwall are combined together again with acetone cleaning cylinder mouth and near zone thereof;
