Abstract
The invention discloses a manufacturing method of a seamless rotary pressing type aluminum alloy rim. An aluminum ally extrusion pipe is adopted, wherein the diameter of the extrusion pipe is the same as the diameter of the rim, the axial length of the extrusion pipe accounts for 60% to 80% of the axial length of the rim, and the size of the extrusion pipe is larger than the size of the rim; through rotary pressing, the extrusion pipe is extended, and the size of the extrusion pipe is reduced, so that the rim is obtained. The shorter aluminum alloy extrusion pipe with the equal diameter and the large size is adopted for manufacturing the rim; on one hand, the extrusion pipe is uniform in texture and very small in internal stress, no bucket effect exists in the manufactured rim, and therefore the weight and the raw material cost of the rim are optimized; and on the other hand, the strength of an extrusion finished product is close to forging strength, the cost is lower. Through the rotary pressing, the size is reduced while the extrusion is axially expanded, the rim becomes more compact, the strength is further improved, and the weight and the raw material cost of the rim are further reduced.
Description
Technical field
The present invention relates to field of hub, be specifically related to a kind of preparation method of seamless rotary extrusion type spinning aluminium alloy wheel rim.
Background technology
Auto industry high speed development, within 2013, Chinese automobile output is just more than 2,000 ten thousand, becomes genuine automobile production first big country.Wheel hub is the vitals of automobile, aluminium alloy wheel hub with lightweight, thermal diffusivity good, advantage attractive in appearance, progressively instead of the status of steel wheel hub; Aluminium alloy wheel hub can be divided into one piece casting type, Integral forge type and combined type three kinds, one piece casting type wheel hub is that current manufacturing cost is minimum, its output accounts for about 90% of wheel hub total growth, the performance of Integral forge type wheel hub is better than Integral forge type wheel hub, but its manufacturing cost is higher, the performance of combined type wheel hub is close to the performance of Integral forge type wheel hub, and manufacturing cost is closer to one piece casting type wheel hub, is subject to the favor of client.
Combined type wheel hub is divided into two panels combined type and three combined types, two panels combined type wheel hub amounts to two panels by wheel rim and spoke and is complex as a whole, spoke is generally cast member or forge piece, and wheel rim is except cast member or forge piece, also has rotary extrusion type spinning wheel rim, current rotary extrusion type spinning wheel rim generally adopts aluminium alloy plate to roll, carry out again made by spinning after being welded into cylinder, the intensity of commissure only has about 95% of aluminium alloy plate, according to wooden pail effect, make the bulk strength of wheel rim up to standard, must guarantee that the intensity of commissure is up to standard, that is, the intensity of aluminium alloy plate must meet together higher than the new standard of wheel rim strength criterion, and improve the most effective way of aluminium alloy plate intensity and increase thickness exactly, this just makes current rotary extrusion type spinning wheel rim must have thicker wall just can guarantee that intensity is up to standard, weight and cost of material increase all to some extent.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of preparation method of seamless rotary extrusion type spinning aluminium alloy wheel rim, can solve existing rotary extrusion type spinning aluminium alloy wheel rim adopts aluminium sheet to roll, be welded into cylinder, commissure intensity is lower, aluminium alloy plate intensity must be increased to guarantee that weld strength is up to standard, cause the problem that rim weight and cost increase all to some extent.
The present invention is achieved through the following technical solutions:
A preparation method for seamless rotary extrusion type spinning aluminium alloy wheel rim, adopts, axial length identical with rim diameter to be wheel rim axial length 60% ~ 80%, aluminium alloy extruded pipe that volume is greater than wheel rim volume, makes that its axial length extends, volume-diminished obtains wheel rim through spinning.
Further scheme of the present invention is, described aluminium alloy extruded pipe is made up of 5 line aluminium alloys or 6 line aluminium alloys or 7 line aluminium alloys.
The present invention's advantage is compared with prior art:
One, adopt isometrical, the shorter and aluminium alloy extruded pipe that volume is bigger to make wheel rim, extruded tube is homogeneous on the one hand, and internal stress is very little, and the wheel rim produced does not exist wooden pail effect, thus optimizes weight and the cost of material of wheel rim; The intensity of extruded product is close to forging on the other hand, and cost is also low, and extruded tube is while spinning makes its axial length extend, and volume also can reduce, and namely becomes finer and close, improves intensity further, is conducive to the weight and the cost of material that reduce wheel rim further;
Two, the extruded tube made of 5 line aluminium alloys or 6 line aluminium alloys or 7 line aluminium alloys, spinning process does not need heating, and technique is simple, energy consumption is low, is conducive to the cost of manufacture reducing wheel rim further;
Three, the size of whole aluminium alloy plate is comparatively fixing, and wheel rim has sizes, and the leftover pieces that cutting is formed are more, and wastage of material amount is large, and extruded tube can intercept random length as required, and raw material availability is high, waste is few.
Detailed description of the invention
A kind of preparation method of seamless rotary extrusion type spinning aluminium alloy wheel rim, adopt, axial length identical with rim diameter to be wheel rim axial length 60% ~ 80%, aluminium alloy extruded pipe that volume is greater than wheel rim volume, make through spinning that its axial length extends, volume-diminished obtains wheel rim, the axial length of described aluminium alloy extruded pipe can draw as calculated according to the difference of its wall thickness; Described aluminium alloy extruded pipe is made up of 5 line aluminium alloys or 6 line aluminium alloys or 7 line aluminium alloys.
