Abstract
The invention discloses a method for molding connection structure for automobile oil pipe. The connection structure comprises a steel pipe, a rubber pipe, and an metal sleeve. Two annular block rings and two annular bumps are formed on the terminal of the steel pipes, the rubber pipe are nested on the annular projection section, the metal sleeve is nested outside the rubber pipe of the annular projection section, which is directly fixed on the first head connecting block ring by the second block ring extrusion molded. A contraction portion is disposed on the metal sleeve on both sides of the annular projection corresponding to the steel pipe, and two O-type ring sealing are added between the steel sleeve and the first head connecting block ring adhering the first bump. According to the invention, sealing points is added to the connection structure, stability is greatly enhanced, thus making the connection structure suitable for higher pressure and stronger temperature pulse cycling ability.
Description
Technical field
The present invention relates to a kind of auto parts and components, specifically is a kind of processing technology of structure of automobile oil pipe.
Background technique
At home, the automobile oil pipe linkage structure is at present: at one one-tenth T-joint of steel tube head welding, this becomes T-joint is to be formed by the metal machining, and insert in the sebific duct steel tube forming termination, and with metallic sheath locking, and this metallic sheath also forms for the metal machining.This complex structure, waste material, many, the increase cost of production of manufacturing procedure.
This is a kind of architecture advances, be directly at two annular bulges of metallic steel pipe end moulding, a spin slot and two annular retaining rings, annular retaining ring is extrusion modling at twice, steel pipe spin slot position and steel bushing connect between second back-up ring all installs O type circle, annular bulge place is with sebific duct, there is metallic sheath the sebific duct outside, and the metallic sheath annular retaining ring is buckled on two annular retaining ring positions of connecting head and at the place, both sides of the annular protrusion of corresponding metal steel pipe contraction, metallic sheath is arranged all is impact briquetting.This structure has solved complex structure, sealability deficiency, has increased the problem of cost of production.But this structure is very high to the structural requirement of equipment and mold.
Summary of the invention
The invention provides a kind of improved automobile oil pipe linkage structure, except that solving oil tube connection structure complexity, cost problem of higher, solve pressure-bearing height, the long problem of the big and high low temperature cycle pulse of pulling-out force demand time requirement simultaneously.
The scheme of invention technical solution problem is:
A kind of linkage structure of automobile oil pipe, it is by the metal steel pipe, sebific duct, metallic sheath, O type circle is formed, it is characterized in that: form two annular bulges and two annular retaining rings at the metallic steel pipe end, annular bulge place is with sebific duct, there is metallic sheath the sebific duct outside that is enclosed within annular bulge place, annular bulge place of corresponding metal steel pipe has two contraction flow regions on the metallic sheath, the metallic sheath top card is in the middle of two annular retaining ring positions, press O type circle of lock in the inner part and between the annular retaining ring at metallic sheath, on the metal steel pipe, be rotary with a groove, and in groove, assemble O type circle by first annular bulge place.
A kind of forming method of linkage structure of automobile oil pipe, it is characterized in that: the linkage structure that includes automobile oil pipe, it is by the metal steel pipe, sebific duct, metallic sheath and O type circle are formed, form two annular bulges and two annular retaining rings at the metallic steel pipe end, annular bulge place is with sebific duct, there is metallic sheath the sebific duct outside that is enclosed within annular bulge place, annular bulge place of corresponding metal steel pipe has two contraction flow regions on the metallic sheath, the metallic sheath top card is in the middle of two annular retaining ring positions, press O type circle of lock in the inner part and between the annular retaining ring at metallic sheath, on the metal steel pipe, be rotary with a groove, and in groove, assemble O type circle by first annular bulge place; Two annular retaining rings are positioned at the metal steel pipe near the metallic sheath position, two annular retaining rings push at twice on the metal steel pipe, mold for the first time an annular retaining ring and two annular bulges, put O type circle again, for the second time by extrusion die near second annular retaining ring of metallic sheath moulding, with glue pipe socket in annular bulge place, and extrusion metal cover, make metallic sheath and first annular retaining ring compress O type circle, utilize the place, both sides of extrusion equipment annular bulge of corresponding metal steel pipe on metallic sheath to be compressed with contraction flow region then.
At first two annular bulges of moulding and a spin slot on steel pipe, and in spin slot, add O type circle, metallic sheath at first is enclosed within on the connecting head, and by extrusion die second annular retaining ring of moulding on connecting head, fix metallic sheath, and make O type circle be extruded the formation sealing, metallic sheath is impact briquetting.
After metal steel pipe and metal casing pressure lock together, between steel pipe and metallic sheath, insert sebific duct, on special mechanical equipment, lock and form.
Placement of the present invention, metallic sheath directly is stuck among two back-up rings of connecting head, metallic sheath directly adopts the mould extruding to be close on first back-up ring, and between metallic sheath and steel pipe, increased O type circle, the steel pipe connecting head adopts two annular bulges to add a spin slot, and in spin slot, add O type circle, the pulling-out force increase that is connected between sebific duct and metal steel pipe is bigger, increased a seal point between metal steel pipe and sebific duct, and put into O type circle in the connecting head spin slot, behind snap close, the stressed sealing of O type circle strengthens sealability greatly, and the reliability of connection is strengthened greatly, thereby can adapt to higher pressure and the more endurance test of wide temperature range, performance obviously increases.Compare with other linkage structures, can finish the processing of metal steel pipe shaping end in the short period of time, metallic sheath is directly pressed lock by mould, and technology is simple, reliable performance.

Fig. 2 is a metallic steel tubular construction schematic representation of the present invention.
Fig. 3 is an assembly structure schematic representation of the present invention.
Embodiment
Referring to diagrammatic sketch 1, the linkage structure of automobile oil pipe is made up of metal steel pipe 1, O type circle, sebific duct 3, metallic sheath 4.Form annular bulge 5, annular retaining ring 6, spin slot 7 and two O type circles 8 and 9 on the metal steel pipe 1, O type circle 8 embeds in the spin slot 7, press the stressed formation sealing in lock back, after another O type circle 9 is close to metallic sheath 4, moulding annular retaining ring 2 extrusion metals cover 4 on the steel pipe connecting head, make O type circle 8 and annular retaining ring 6 form sealing closely, use special device and Die lock catch metallic sheath at last, sebific duct 3 is close to forms sealing on the steel pipe.
Annular bulge 5 on the metal steel pipe and connecting head annular retaining ring 6 and 2 structures are by the shaping die extrusion modling; Metallic sheath 4 is by low-carbon (LC) cold drawing punching stretch forming.
