Description
Technical field
The present invention relates to the resonant rod manufacturing process, relate in particular to a kind of method that adopts the control moulding of flowing to make resonant rod.
Background technology
The whole world enters the information age, and mobile communication has critical role in the information transmission, and along with the develop rapidly of mechanics of communication, radio-frequency technique has irreplaceable effect.And the resonant rod part that in radio-frequency technique, is absolutely necessary, the annual use amount in the whole world is at tens million of.Along with the significantly raising of China's equipment manufacture level, well-known in the world communication apparatus manufacturing company is all in China's buying or manufacturing related components.
The dimension precision requirement of resonant rod is very high, complex structure.Traditional manufacturing process generally all is the lathe manufacturing, and this mode is inefficiency and consumed a large amount of precious metal resources not only, and stock utilization is less than 30%.The technology that present also useful sheet metal stretching and multistage cold former are produced resonant rod.The resonant rod of sheet metal stretching is because tensile properties, the R angle of material bending part causes the electric index of system lower, and multistage cold former is the equipment of producing screw and so on standard component in enormous quantities, because efficient is high, so the lowest manufactured amount to part has requirement again, because the size of resonant rod is adjusted at any time with work condition environment, so also can't be widely used at present.Above various reasons has caused the obstacle of resonant rod production, thereby has seriously restricted the development of communications industry.
Summary of the invention
The objective of the invention is to solve the problem that prior art exists, a kind of method that adopts the control moulding of flowing to make resonant rod is provided, in carrying out the Compound Extrusion production process, do not have cutting and produce, saved material and human cost, effectively reduced energy consumption.The minimum minimum quantity of an order of product-free and saved a large amount of die debugging times.Simultaneously, Compound Extrusion realizes one-shot forming by single station, and working (machining) efficiency is higher.
In order to reach above-mentioned technical purpose, the present invention by the following technical solutions:
A kind of method that adopts the control moulding of flowing to make resonant rod, this resonant rod comprises the body of rod and is positioned at the poroid die cavity at body of rod two ends that this method may further comprise the steps:
