Abstract
The invention provides a method for processing a nut seat bore of a vehicle wheel spoke. On a hydrodynamic press, an upper extrusion head is fixed on a slide block of a machine tool through an upper die seat and an upper template; a lower extrusion head is fixed on a working table of the machine tool through a lower die seat and a lower template; the upper extrusion head and the lower extrusion head are arranged on the same line, and are standard balls; opposite extrusion can be realized by up and down movement of the slide block to complete curve generating operation of the nut seat bore; and actions are workpiece placement positioning, slide block descending, extrusion processing, slide block ascending and workpiece extracting in turn. Compared with the prior profile copying, the method has the advantages that the curve surface of the nut seat bore has accurate extrusion size and smooth surface; size and shape between seat bores have higher consistency; the method can be operated easily, and has high production efficiency; and the method improves internal tissue of a material in processing district, and improves density, thereby improving mechanical property.
Description
Technical field:
The present invention relates to a kind of vehicle wheels spoke nut seat hole production and processing method.
Background technology:
Processing for the nut seat hole, original processing method is " profiling " cutting, process nut seat hole sphere curved surface with the ball cutting drill head that sharpening is good in advance exactly, spherical shape depends on the geometry of blade fully, randomness is bigger, and machining accuracy is low, and production efficiency is low, skill level to the operator requires height, and labour intensity is big.And the height of nut seat hole machining accuracy has directly determined the quality of bond strength between wheel and the axle hub again.If nut seat hole curved surface can not fully be fitted with the nut curved surface, wheel just comes off easily in long-term operation, in jolting, vibrating so, causes security incident.
Summary of the invention:
The purpose of this invention is to provide a kind of method for processing wheel spoke nut seat hole, for the processing in nut seat hole provides a kind of high-precision, production technology efficiently.
The objective of the invention is to realize as follows: this method adopts upper and lower two relative standard ball pearls to dash that good bolt bottom outlet carries out the subtend extruding and the processing that realizes two-way nut seat hole curved surface in advance pre-.Concrete scheme is: on hydraulic press, last extrusion head is fixed on the lathe slide block by upper bolster, cope match-plate pattern, following extrusion head is fixed on the platen by die shoe, lower bolster, last extrusion head and following extrusion head are on same straight line, last extrusion head is the standard ball with following extrusion head, the upper and lower motion that utilizes slide block is pushed the curved surface forming operation of finishing the nut seat hole to realize subtend, action be followed successively by workpiece placement positioning, slide block down, to squeeze processing, slide block up, take out workpiece.
The present invention compares with original profiling, mainly has following distinguishing feature:
(1) accurate, any surface finish of nut seat hole curved surface extruding size: a seat hole dimension precision of extruding can reach the IT8-9 level, and surface roughness can reach
(2) size between each hole, shape uniformity are higher: what original processing method adopted is profiling, bore processing with the bull that efficient is higher, the machining shape in seat hole depends on the geometry of blade fully, and problem is, the sharpening of each drill bit will lean on the operator to finish by rule of thumb, subjective factor is bigger, geometry there are differences unavoidable between each blade, and do not had selectively and inherit by a seat hole, so that machining accuracy is lower, error is bigger, generally can only reach the IT10-11 level.And the extrusion head that this processing scheme adopted all is the standard ball, the maximum of size, form error only is 0.003 millimeter, and be not subjected to the influence of subjective factors such as operator's technical merit substantially, thereby can be easier to, more stably guarantee the machining accuracy of workpiece, uniformity is higher;
(3) easy operating, production efficiency height: because the sharpening of drill bit will be by manually finishing, this just requires the operator that master hand will be arranged, rich experience, and time enough is arranged, with through examining, the sharpening of ball cutting drill head each will be with 1-2 hour, increased non-cutting time significantly, so production efficiency is lower.Adopt this method processing then to need not sharpening, easy and simple to handle fast, reduced non-cutting time significantly, improved production efficiency;
(4) improve the interior tissue of processing district material, improve density, thereby raising mechanical performance: since this technology utilization the cold work reinforced characteristic in the metal material cold deformation process, be in the extrusion process, near the seat hole material is in the three-dimensional compressive stress state, pore in the tissue and loose be compacted, atomic distance reduces, and form rational fiber flow direction, cause the metal inside friction to increase, resistance of deformation also increases thereupon, thereby the raising that all strengthened of mechanical properties such as the intensity of product processing district, rigidity, the machining band that forms far above machining.
The specific embodiment:
On hydraulic press, last extrusion head is fixed on the lathe slide block by upper bolster and cope match-plate pattern, following extrusion head is fixed on the platen by die shoe and lower bolster, last extrusion head and following extrusion head are on same straight line, last extrusion head is the standard ball with following extrusion head, the upper and lower motion that utilizes slide block is pushed the curved surface forming operation of finishing the nut seat hole to realize subtend, action be followed successively by workpiece placement positioning, slide block down, to squeeze processing, slide block up, take out workpiece.
