Abstract
This invention relates to an EP2 air-core or called Germanic air-core, which comprises a main body with a step-type via hole, and on the top of the body is arranged an external screw thread used for connecting the aerating device of car tire; on the lower of the thread is arranged a cylinder with step, below the cylinder is a circular slot, and below the slot is arranged an inflating cylinder; the circular slot has a sealing ring, and below the sealing ring is a crosswise vent hole; the main body is made up of zinc-base alloy material, and its accessories such as via hole, external screw thread are shaped with zinc-base alloy material by hot-case technology. The invention uses zinc alloy material instead of copper alloy, which can be widely used in the tire aerating device of bicycle, power assist vehicle, battery-driven truck and mini electric vehicle.
Description
Technical field
The present invention relates to a kind of Tire Inflation System.Particularly relate to a kind of EP2 gaseous core that adopts zinc base alloy to make.The EP2 gaseous core is referred to as to call moral formula gaseous core again, and it is widely used in the inflator of vehicle tires such as bicycle, storage battery car and small-sized electric car.
Background technique
At present, the manufactured materials of the domestic EP2 gaseous core that generally uses and method of manufacturing technology be by the bar of Cuprum alloy as raw material through turning be shaped, account for the hole, screw thread is processed and electroplating surface processing etc. is finished by multiple working procedure; This not only takes a lot of work, time-consuming, and what is more important is the strategic resource of national precious as raw-material Cuprum alloy, and price is higher; Making the EP2 gaseous core and be widely used in the inflator of various types of vehicles tire with Cu alloy material is very unfortunate really.
Summary of the invention
Purpose of the present invention is exactly in order to overcome above-mentioned deficiency of the prior art, and a kind of EP2 gaseous core that adopts zinc base alloy thermoforming, manufacturing process advantages of simple is provided.
The objective of the invention is by providing a kind of EP2 gaseous core to realize with following manufactured materials and method of manufacturing technology, it comprises that one has the gaseous core main body of interior step-like through hole, the upper end of described gaseous core main body is provided with the outside thread of the inflator that is used to connect vehicle tyre, described outside thread below is provided with cylndrical surface with the level, below, described cylndrical surface is provided with the annular groove of a dress seal ring, described annular groove below is provided with the inflation cylinder, described inflation cylinder lower end is provided with the hemisphere outer rim, the end of described hemisphere outer rim is provided with an aperture, described aperture is connected with step-like through hole in the described gaseous core main body, the inner of described hemisphere outer rim, and above described aperture, be provided with one and stop the packing that leaks of inflation, described annular groove is provided with a seal ring, and described seal ring below is provided with the horizontal communication hole of a described gaseous core main body.
Described gaseous core main body is to be made by Zn-base alloy.The Zn-base alloy of described gaseous core main body is the zinc base alloy of zinc content more than 80 percent.
The annular groove of described step-like through hole, described outside thread, described cylndrical surface with the level, described dress seal ring, described inflation cylinder are the injection moulding technological formings by Zn-base alloy.
Behind the injection moulding technological forming, carry out the cylinder deburring operation, and process described hemisphere outer rim, described aperture, described horizontal communication hole, and then carry out electroplating processes, promptly finish whole making of EP2 gaseous core of the present invention.
Compared with prior art, the invention has the advantages that: 1. the manufactured materials that adopts zinc alloy reduces production costs greatly with the instead of copper alloy; Simplified manufacturing technique, shorten the manufacture cycle, enhance productivity; 3. can be widely used in the inflator of vehicle tires such as bicycle miscellaneous, self-service car, storage battery car and small-sized electric car.
Description of drawings
Fig. 1 is a structural representation of the present invention:
Embodiment
Below in conjunction with accompanying drawing embodiment invention is described in further detail.
Fig. 1 shows a mode of execution of EP2 gaseous core of the present invention.The EP2 gaseous core is called moral formula gaseous core again, and it comprises that one has the gaseous core main body 1 of step-like inner via hole 12.
The upper end of gaseous core main body is provided with the outside thread 11 of the inflator that is used to connect vehicle tyre, outside thread 11 belows are provided with the cylndrical surface 14 of band step 13,14 belows, cylndrical surface are provided with the annular groove 15 that a dress seal ring is used, annular groove 15 belows are provided with an inflation cylinder 16, inflation cylinder 16 lower ends are provided with hemisphere outer rim 17, the end of hemisphere outer rim 17 is provided with an aperture 18, and aperture 18 is connected with the step-like inner via hole 12 of described gaseous core main body 1; The inner of hemisphere outer rim 17 also is provided with one and stops the packing 3 that leaks of inflation above aperture 18.
Device one seal ring 2 on the annular groove 15, seal ring 2 belows are provided with the horizontal communication hole 4 of a gaseous core main body.
The material of gaseous core main body 1 employing zinc alloy and injection moulding technology are to substitute the Cu alloy material and the processing technology thereof of prior art; Wherein the annular groove 15 of the cylndrical surface 14 of the step-like inner via hole 12 of gaseous core main body, outside thread 11, band step 13, dress seal ring, inflation cylinder 16 are that injection moulding technological forming on 25 tons of die casting machines is finished, and needn't process at instrument lathe, to simplify technology, to shorten the manufacture cycle and can reduce production costs again.
Zn-base alloy is the zinc base alloy of zinc content more than 80 percent.
The cylndrical surface 14 of above-mentioned step-like inner via hole 12, outside thread 11, band step 13, the annular groove 15 of dress seal ring, inflation cylinder 16 each working surface carry out the cylinder deburring operation behind the injection moulding technological forming, and processing hemisphere outer rim 17, aperture 18, horizontal communication hole 4, and then carry out electroplating processes, promptly finish whole making of EP2 gaseous core of the present invention.
