Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is carried out detailed explanation.
Each reference character title is in the accompanying drawing: water-cooling tube 1, spring clip 2, band 3, braided sheath 4, interior pipe rubber layer 5, fibre threads enhancement layer 6, outer tube rubber layer 7.
With reference to Fig. 1; A kind of engine cooling water pipe assembly; Comprise water-cooling tube 1, spring clip 2, band 3 and braided sheath 4; Wherein water-cooling tube 1 is a body, and it is followed successively by the interior pipe rubber layer 5 processed by the ethylene propylene diene rubber that contains peroxide vulcanizing agent and rubber bond, fibre threads enhancement layer 6 from inside to outside and is made up of outer tube rubber layer 7 bondings that the ethylene propylene diene rubber that contains peroxide vulcanizing agent and rubber bond is processed.The peroxide vulcanizing agent sulfuration makes the heat resisting temperature of rubber pipe bring up to 170 ℃ by 150 ℃, and cure time shortens.The increase of rubber bond makes saves toluene coating operation, and the adhesion between knitted layer and the outer sebific duct is improved.
Water-cooling tube 1 has 9 the arc-shaped bend sections and 10 space sections of trend that link to each other successively through the arc-shaped bend section that change water-cooling tube 1 angle of strike; 10 space sections of trend are straightway.The a plurality of bend angle of water-cooling tube and complex spatial trend can satisfy Vehicle Engine Structure complicacy, requirement that metal parts is intensive.
Interior pipe rubber layer 5 inner tube diameters are 9mm～10mm, and outer tube rubber layer 7 outer externals diameter of pipe are 16mm～17mm.Advantages such as itself has good springiness ethylene propylene diene rubber, and is powerful high, and resistance to heat is good, it is the first-selection of making the engine cooling water pipe that is used for the GAMMA of SGM series vehicle.Inner tube diameter Grain Full foot standard-required meets the designing requirement of metal pair fitting fully.
Fibre threads enhancement layer 6 is aramid line layers that the knitting machine by 12 pin numbers knits out on interior pipe rubber layer 5 with 4mm～5.5mm pitch; The aramid line layer is fixed in the middle of the inner and outer pipes rubber layer, and bonding with inner and outer pipes.Aramid line intensity is high, elongation percentage is little, pulse performance and good heat resistance, adopts this material as enhancement layer, and it is higher to make water-cooling tube and throttle body heat the intensity of sebific duct.Consider on structural design simultaneously that the light softness of body, good bending property, manufacturing efficiency are high, knitting machine is selected 12 pins, and pitch design can be selected 4mm～5.5mm, can satisfy the bursting pressure of pipe, has practiced thrift cost again, has guaranteed the bending properties of body.
The two ends of water-cooling tube 1 are fitted with the spring clip 2 of tightening water-cooling tube (1); Spring clip 2 is that water-cooling tube 1 is fastened on the circular metal connection fittings on the interfacing part.Water-cooling tube 1 is installed on the interfacing part, fastening with spring clip 2, can guarantee water-cooling tube 1 do not come off, water-tight.
Outer being fitted with of water-cooling tube (1) has netted pipe structure and can extend to original 150% braided sheath (4).Braided sheath 4 is tightened the space easily and is moved towards complicated water-cooling tube 1 as the protective casing of water-cooling tube 1, can effectively prevent cooling water pipe 1 passive interference wear, increases the Security of car steering.Its distinctive net-like character also has good ventilation effect, can in time spread the heat of water-cooling tube 1.
Water-cooling tube 1 two ends have the coding of being convenient to the subsequent handling mistake proofing to indicate.Promptly carry out online coding after pipe is extruded and indicate, be convenient to vulcanization process and assembly process mistake proofing.
The making of the utility model at first is mixing at interior sizing material with containing peroxide vulcanizing agent, rubber bond and ethylene propylene diene rubber; After sizing material put into straight type head extruder extrude inner glue layer; Select the knitting machine of 12 pin numbers select 4mm～5.5mm pitch on the interior pipe rubber layer of extruding with aramid line braided fiber line enhancement layer; Glue-line outside back entering T type head extruder is extruded outside the semi-finished product that preceding step obtains; Cut off sebific duct then, the mould that sebific duct adopts import mold tool steel and two ends to attach the names of pre-determined candidates is worn mould, wear and put into sulfurizing pot behind the mould and carried out peroxide cure 20 minutes; At last sebific duct is washed, and carry out coding sign, assembling sheath clip, finally obtain product.
