Description
Technical field
The present invention is related to the manufacture method of a kind of bicycle pattern hub shell, a kind of does not limit shape, manufacture process is short and waste material is few and the bicycle hub casing manufacturing method of low cost.
Background technology
The at present vehicles of individual, although mostly based on locomotive or automobile, but, bicycle has the advantages such as do not take up space and mobility is high due to it, the most all possesses the status of its non-mainstream vehicles.And prevailing due to leisure wind and trend of environmental protection in recent years, and bicycle just has environmental protection and motion two big advantages concurrently, for the moment between cause the agitation riding bicycle, while the most also achievements bicycle market open greatly.Well known, flower hub transmits at the power of bicycle has very important status, and the manufacture method production efficiency yet with existing bicycle hub is the best, and the many dealers of order are under this pandemic agitation of ripple bicycle, its due income still cannot be substantially improved, the most pitiable.
Through looking into, current existing bicycle hub manufacture method, nothing more than forging and the big main flow of turning two, its manufacture process is described below the most respectively with shortcoming.
As a example by forging.The program of forging bicycle pattern hub shell must process by forging and molding several times, it is processed boring the most again, and every time processing it is necessary to have some, processor just can order be carried out forging processed, therefore its not only cost is high, speed slow and low precision, furthermore the hub shell of some special shape, cannot be completed by the way of forging at all.
Again as a example by direct turning.Must first draw materials from being thick stock more than the round metal bars of flower drum shell maximum outside diameter, then round metal bars is cut into a predetermined length, then recycling turning-milling complex processing machine in addition turning, milling and boring.Due to turning with milling be with whole pole start processing, therefore can produce considerable waste material, in addition to the waste causing raw material, also improve manufacturing cost virtually, reduce its market competitiveness.
Summary of the invention
The present inventor is high for above-mentioned forging bicycle hub cost, speed slow and the defect such as low precision;Directly with the thick embryo pole more than flower drum shell maximum outside diameter, directly footpath row is with turning, Milling Process, cause the shortcoming that bicycle hub waste material is many and cost is high produced, in line with the spiritual and excelsior purpose work with perseverance, actively constantly studied improvement, and through long-term endeavour and test, the present invention is designed in exploitation finally.
The present invention is to solve above-mentioned problem, it is provided that a kind of do not limit shape, manufacture process is short and waste material is few bicycle hub casing manufacturing method.
The manufacture method of the bicycle pattern hub shell of the present invention, mainly comprises the following steps:
Extrusion forming: will need to make the metal material of hub shell, is manufactured into the material bar that a cross section is the strip of geometry kenel in the way of extrusion forming;
Cut: material bar is cut into material block according to hub shell quantity to be produced;
Heat treatment: utilize heat treatment mode, improves the hardness of material block itself, the scale error of shrinkage after reducing course of processing flatulence of heat type and processing;
Digital control processing machines: material block processes one first disk body (31), the second disk body (32) and a brake disc mounting seat (33), and forms the perforation of multiple ring-type equidistant arrangement on the first disk body (31) with the second disk body (32) respectively;And
Surface processes.
Described it is processed as turning, milling and drilling via formations.
Preferably, the different two sides of this material bar forms the first forming part (11), the second forming part (12) and the 3rd forming part (13) respectively, connect this first forming part (11) and the second forming part (12), it it is one first axle portion (14), and connect this second forming part (12) and the 3rd forming part (13), it is one second axle portion (15);Wherein, this first forming part (11) is suitable with the height of the second forming part (12).
Preferably, this first forming part (11) and the second forming part (12) are respectively provided with an inside setting and the first rake (111) in correspondence with each other and the second rake (121).
Preferably, after material bar is cut into material block according to hub shell quantity to be produced, the width of material block is equivalent to the height of the first forming part (11).
Preferably, digital control processing machining procedure divides into roughing and polish.
Preferably, after roughing program, this first forming part (11), the second forming part (12) and the 3rd forming part (13), form one first wheel body (21), the second wheel body (22) and third round body (23) respectively, and this first rake (111) and the second rake (121), form one first ring rake (211) and the second ring rake (221) the most respectively;This first axle portion (14) and the second axle portion (15) form one first axostylus axostyle (24) and the second axostylus axostyle (25) the most respectively.
Preferably, after finishing procedures, this first wheel body (21) and the second wheel body (22) form one first disk body (31) and the second disk body (32) respectively, and this first ring rake (211) and the second ring rake (221) form one first ring protuberance (311) and the second ring protuberance (321) the most respectively;This third round body (23) then forms a brake disc mounting seat (33).
Preferably, this surface processing routine uses anodising.
The method have the advantages that
Material used in the present invention is first with extrusion forming technology, by metal material pull material bar into strips, cutting in bulk according to quantity to be processed again, do not limited by quantity, the technology extruded due to metal is the most ripe, therefore can be by extruding and cutting action, material bar is cut into complete after the fairly close material block of size, therefore, during digital control processing machines, can amount of waste produced by this manufacture process be down to minimum, in addition to reducing cost, also help environmental protection.Furthermore, method provided by the present invention, can thoroughly solve to manufacture with forging method that bicycle hub cost is high, speed slow and the shortcoming of low precision, meanwhile, use this method also can solve the shortcoming that the produced amount of waste material of turning manufacture method is huge.
