Description
Technical field
The present invention relates to mobile phone technique field, particularly relate to a kind of preparation method of mobile phone metal center.
Background technology
The metal shell using on mobile phone not only has exquisite outward appearance, and has the advantages such as feel exquisiteness, wear-resisting, shatter-resistant, anticorrosive, discarded easy reclaiming utilization, thereby liking of consumer extremely.Wherein, center is as the important part of mobile phone, and its smooth in appearance, inside structure are comparatively complicated.The common practice of mobile phone center is at present: 1, the sheet materials such as monoblock aluminium alloy, stainless steel are cut, bore milling machine-shaping through CNC, this kind of way raw materials consumption is maximum, CNC processing capacity, and working (machining) efficiency is low, and cost is high; But technology is relatively simple, it is the topmost form processing of metal current mobile phone center.2, the sheet material processes such as thinner aluminium alloy, immortal steel are forged, reach required processing dimension, reduce CNC processing capacity, to reduce manufacturing cost.But this form processing processing procedure is long, specification requirement is high, industry only has minority enterprise to manufacture.Above-mentioned two kinds of production technologies all can form at the mid portion of mobile phone center large-area waste part, and then excise mid portion by CNC; Both there is the problems such as complex process, inefficiency.3, by die casting under the alloy high-temp molten conditions such as aluminium alloy, stainless steel, then be processed into center through CNC; At the bottom of this kind of process costs, easily batch production, but the product external surfaces density of producing is inadequate, does not reach the appearance requirement of beautiful exquisiteness, by industry, is not adopted at present.
Summary of the invention
In order to address the above problem, the object of the invention is to, provide a kind of technique simple, the preparation method of the mobile phone center that efficiency is very high.
The present invention is achieved through the following technical solutions:
A kind of preparation method of mobile phone center, first mobile phone center alloy material used is made to the extrusion section bar of strip hollow by extrusion modling operation, then adopt CNC lathe that the extrusion section bar of described strip hollow is cut according to thickness requirement, finally the object cutting down is carried out to post processing and obtain described mobile phone center.Wherein, the extrusion section bar of described hollow inner side is directly squeezed into target product desired structure.The extrusion section bar of described hollow makes target product desired structure by alloy material being heated to carry out extrusion modling operation under soft condition.
Preferably, in described extrusion modling operation, extrusion temperature is 530～750 ℃.
Preferably, in described extrusion modling operation, extrusion speed is 1～3m/min.
Preferably, in described extrusion modling operation, extrusion molding gained workpiece carries out strong wind cooling Quenching Treatment again.
Preferably, in described extrusion modling operation, before extrusion molding first by alloy soaking and carry out quick cooling processing.
Preferably, in described alloy material, the mass percent of each composition is: Cu0.5～4.0%, Si10.0～12.0%, Mg0.02～0.3%, Zn≤0.1%, Fe≤1.3%, Mn≤0.5%, Ni≤0.5%, Sn≤0.35%, Al3.0～11.5%.
The performance requirement of described alloy material: shear strength 193～296Mpa, 395～700 ℃ of fusion temperatures.
The performance requirement of described alloy material: tensile strength 247～410Mpa, percentage elongation 5～25%.
The present invention first makes the extrusion section bar of strip hollow by mobile phone center alloy material used by extrusion modling operation, then the extrusion section bar of described strip hollow is cut with CNC lathe, finally the object cutting down is carried out to post processing and obtains described mobile phone center.From existing to excise mid portion by CNC different, the present invention inner side directly extrusion modling becomes target product desired structure, and then by CNC lathe, described list structure is evenly cut and can obtain mobile phone center product by desired thickness.This manufacturing process is simple, and efficiency is very high, saved a large amount of materials, manpower, lathe expense, and production efficiency promotes greatly simultaneously, and raw material consume and reduce more than 70%, and improving productivity is more than 60%, and decrease machining cost is more than 60%.Wherein, in order to reach the quality standard of final products, reach more succinct smooth technique simultaneously, reduce scrappage cost-saving, coordinate production method of the present invention, the constituent content of alloy and physico-chemical property also have certain requirement.
