Description
Technical field
The present invention relates to the machining process technical field, especially a kind of process of taper wheel rim outer surface being carried out annular knurl processing.
Background technology
For increasing the coefficient of friction between wheel and the tire; Increase frictional force; To overcome and to prevent the relative slip between tire and the wheel; Some wheel rim, especially the engineering truck wheel rim of operation under the not enough or abominable working environment at tire pressure, and large-scale wheel rim often need be at its surface extrusion decorative pattern with the position of tire crimping.The width of this decorative pattern, the degree of depth and spacing all have certain requirement.The processing technology of present this decorative pattern be adopt wheeled knurling tool on lathe to rotary work piece the extruding of rolling accomplish; And the processing of this large-scale wheel rim decorative pattern is normally accomplished at vertical machine, and wheel rim is installed on the machine tool chief axis, and knurling tool is contained on the tool slide; During process operation; Start machine tool chief axis and drive the wheel rim rotation, then knurling tool is pressed to the surperficial certain depth that wheel rim need be processed, make the rotation wheel rim under the extruding of knurling tool, form decorative pattern.
Existing typical rim serrations method is such:
The process equipment that adopts is common vertical lathe, and the knurling tool of employing is to be contained on the annular knurl knife bar through wheel shaft by a columniform knurled wheel to constitute the axis normal of the axis of knurled wheel and annular knurl knife bar;
The step of annular knurl operation is: the first step, earlier the wheel rim axis vertically is installed on the vertical lathe workstation towards ground, and the knife bar of knurling tool is contained on the knife rest of vertical lathe, the knurled wheel rotation of knurling tool and wheel rim axis of rotation are parallel to each other; Second step, start lathe, the X axis feeding of knife rest along continuous straight runs of operation lathe drives knurling tool along the X axis feed, extrudes decorative pattern on the wheel rim that knurling tool is pressed on rotating; If the decorative pattern of wheel rim is longer; Or the embossing position of wheel rim is a taper surface; Just need the operation knife rest to make X axis and, make knurling tool roll out to the line motion decorative pattern in the shape of a spiral with respect to wheel rim embossing place of wheel rim along the Z that moves up and down of the knife rest ram feeding that axially links.
And the annular knurl position of existing wheel rim mostly is a taper surface, adopts above-mentioned existing rim serrations method can have following point:
1, the knurled wheel rotation owing to wheel rim axis of rotation and knurling tool is parallel to each other; The cylindrical knurled wheel of knurling tool can only contact with the rim surface extruding with the part wheel limit of one of which end; As shown in Figure 1, contact-making surface is little, and the only getable annular knurl line length of roll extrusion one circle is several millimeters; And the length requirement of the annular knurl line of wheel rim is tens millimeters generally speaking, and the degree of depth does not reach requirement yet.For reaching the requirement of decorative pattern length, need knurling tool to do X axis and the Z feeding that axially links, through obtain the decorative pattern band of sufficient length in the roll extrusion of rim surface multi-circle spiral flow.The shortcoming of this rim serrations method is that the decorative pattern that needs the roll extrusion of many circles to roll out is of poor quality, and the dark other end of decorative pattern one end that each circle extrudes is shallow, if two adjacent rings annular knurl line spacing is too small, annular knurl line as shown in Figure 1 can takes place do situation; If two adjacent rings annular knurl line spacing is excessive, can cause the blank tape between decorative pattern again, the coefficient of friction that the decorative pattern that these situation all can cause rolling out forms the relative tire of wheel rim descends.
2, owing to need knurling tool to do X axis and the Z feeding that axially links, therefore, keep each circle that the control to pattern depth is had big difficulty, operator's technical ability is had relatively high expectations, labour intensity is big, inefficiency.
3, only by the part wheel limit and rim surface extruding annular knurl of knurled wheel one end of knurling tool, cause a small amount of contact portion wearing and tearing quickening greatly of the knurled wheel of knurling tool easily, and other positions are again less than utilization, knurling tool is shortened service life greatly.
4, because the wheel rim clamping can depart from the centre of gyration; Clamping wheel rim can have that circularity changes due to the distortion; So that knurling tool can produce circular runout to the roll extrusion point of wheel rim; If adopt fixed X axis of weighing apparatus and the Z feeding that axially links to carry out annular knurl and operate to knurling tool, the degree of depth that knurling tool is pressed into surface of the work will cause the decorative pattern that processes deep mixed to the circular runout of the wheel rim centre of gyration because of the roll extrusion point; If adopt to control manually knurling tool is adopted fixed X axis of weighing apparatus and the Z feeding that axially links, it is consistent then not only also to cannot say for sure to demonstrate,prove the pattern depth that processes, and be easy to produce decorative pattern blank tape between foregoing circle or enclose between the mutual interference of decorative pattern.
