Description

Iron modeling combination super abrasive high intensity float grease seal ring and its manufacturing method
Technical field
The present invention relates to machinery fields, mould combination super abrasive high intensity float grease seal ring and its system more particularly to a kind of iron Make method.
Background technique
Floating oil seal metal rings quality core point is the superiority and inferiority of the sealing performance of working face bright band, is embodied in wear-resistant work Make the length in service life.And iron hoop specification size is pressed, working face bright band 3-5mm width is by point of accumulation.The wide then two rings patch of bright band Conjunction face adsorption capacity is excessive, abutting it is too dead, lubricating oil infiltration is not entered, easily cause two iron hoop lockings and cushion rubber occur and skids rotation, Cushion rubber rotation abrasion is exceedingly fast, oil leak immediately;After one iron hoop working face bright band abrasion loss of float grease seal reaches 2mm simultaneously, this is a pair of Friction pair just loses the height of 4mm.This will lean on the rebound strength of cushion rubber to fill up.Ordinary circumstance is that 4mm or more is sprung back by cushion rubber It does not compensate.Even if at this moment cushion rubber does not have aging, due screen resilience is not lost, but should be unable to do what one wishes yet.More In addition the more wear-resisting more permanent work of then cushion rubber of iron hoop, aging is stiff to exceed severity, goes to make up due to iron hoop abrasion without screen resilience at all Caused by relaxation gap.The fitting of two iron hoops is not tight, and binding face unclamps, and gap enlargement occurs as soon as permeability so that oil leak, causes to seal Failure, it is necessary to shut down replacement.Iron hoop and cushion rubber composition two-stage sealing, either party fails, and oil leak occurs, just needs to change.Cushion rubber, Iron hoop equivalent life is most economical, scientific optimum choice.It is thus found that wearing layer thickness be no more than 3mm, be enough it is enough, It is economical suitable.Thickness is exactly extra waste to wearing layer again.If with the material of super abrasive, longer, rubber the time required to abrasion 2mm Cushion rubber is also that cannot stand.
Summary of the invention
In view of the above-mentioned problems, the present invention is intended to provide a kind of iron modeling combination super abrasive high intensity float grease seal ring and its manufacture Method, it is less to make to fill out the wear-resistant material being fused in " u "-shaped annular groove, more economical, optimization, not only enough but also without extra waste;It is ingenious Ground is combined into high-intensitive super abrasive float grease seal ring to mould Dai Gang.
Technical solution of the present invention:
A kind of iron modeling combination super abrasive high intensity float grease seal ring, including plastics ring body, the working face of the plastics ring body On iron sheet ring is installed, the iron sheet ring includes the " U "-shaped annular groove in cross section, in annular groove be filled with wear-resistant material layer, institute State the hold-open catch being equipped on the outside of iron sheet ring for preventing iron sheet ring mobile relative to plastics ring body, the iron sheet ring it is interior Side is equipped with the stationary jaw for fixing iron sheet ring, and inside flange, the plastics ring body are provided at the top of stationary jaw On offer the fluting for facilitating and placing O-shaped rubber ring, the iron for installing iron sheet ring is offered on plastic hoop body running face Skin ring mounting groove offers the bayonet lock insertion groove for facilitating insertion hold-open catch, in iron sheet on the inner sidewall of iron sheet ring mounting groove The lower edge of ring mounting groove offers the claw mounting groove for facilitating stationary jaw to install, and offers at the top of claw mounting groove conveniently The flange slot of flange insertion.
The lower edge of the working face of the plastics ring body is also respectively provided with for allowing lubricating oil to can smoothly enter into fuel feeding inclined-plane Oil inlet inclined-plane.
The thickness of scale of the iron sheet ring is 1-2mm.
The width of rebate of the annular groove is 2-5 ㎜.
A kind of manufacturing method of iron modeling combination super abrasive high intensity float grease seal ring, comprising the following specific steps
The hollow iron sheet round tube that the iron plate or pipe skin thickness that step 1 passes through 1-2mm are 1-2mm is processed to form " u "-shaped Annular groove;(selected according to floating sealing ring size dimension model difference)
Step 2 welds 2-6 hold-open catch in the outside of " u "-shaped annular groove at equal intervals, in the inside etc. of " u "-shaped annular groove 2-6 stationary jaw of welding of spacing, the direction that the top of stationary jaw is open opposite to " u "-shaped annular groove carry out flange;
Step 3 fills out molten super abrasive metal or nonmetallic materials in " u "-shaped annular groove, "u"-shaped groove is tamped to be formed it is wear-resisting Work bright band layer iron sheet ring finished product;
Step 4 selects engineering plastics moulding according to the specification shape respective production plastic hoop mould of iron sheet ring Injection molding, which is carried out, in material ring body mold forms plastics ring body;
The iron sheet ring finished product that step 3 makes is embedded into the corresponding position in plastic hoop body running face by step 5, forms iron Modeling combination super abrasive high intensity float grease seal ring.
The production method of " u "-shaped annular groove is in the step 1, and the iron sheet of 1-2mm thickness is corresponded to length truncation by model; Iron sheet after truncation is heated by medium frequency electric sensing apparatus, and the iron sheet after heating is rolled into " u "-shaped through muller, then is bent into while hot Circle is linked into complete " u "-shaped annular groove with laser welding.
Another production method of " u "-shaped annular groove is in the step 1, and by pipe skin depth 1-2mm, internal diameter is the sky of 2-5mm Length needed for heart iron sheet round tube presses product is truncated, and the hollow iron sheet round tube after truncation is converted into annulus and weldering is linked to be circle, then The diametrical direction horizontal resection along hollow iron sheet circle is splitted again, becomes two " u "-shaped annular grooves.
In the step 3, iron sheet ring also needs to polish by end face after processing is completed, reaches its flatness, finish Floating sealing ring bright band face quality standard.
Compared with prior art, the beneficial effects of the present invention are: compared to traditional all-metal floating sealing ring, in " u "-shaped annular groove It fills out molten metal or nonmetallic ultrawear-resistant material weight only accounts for 1.5%-2% or so, use the best steel to make the knife's edge, dosage is few, at low cost; The working face melted due to precisely having selected ultrawear-resistant material component to fill out into " u "-shaped annular groove as floating sealing ring, wearability highlight;Make matter Tremendous increase is measured, super durable, cost performance is high;For ring body to mould Dai Gang, material cost is lower, and the market competitiveness is strong;Energy conservation and environmental protection, it is several There is no emissions;Materials procurement is easy, cost decline.
