Abstract
The invention provides a vehicle wheel blank with a reduced end surface deforming. Partition grooves are formed in the junction of two split side molds of the blank rim end surface of the cast blank; partition grooves are formed in the middle of a single side mold of the blank rim end surface of the cast blank; the number of the partition grooves is eight; the depth of each partition groove is 0.1 to 1 times of the lip height of a positioning wheel; the lower limit of the width of the upper end of each partition groove is the lip height of the positioning wheel; the upper limit of the width of the upper end of each partition groove is one sixteenth of the perimeter of the vehicle wheel blank; the lower limit of the width of the lower end of each partition groove 1 is 0; and the upper limit of the width of the lower end of each partition groove 1 is one sixteenth of the perimeter of the vehicle wheel blank.
Description
Technical field
The present invention relates to wheel and manufacture field, relate in particular to a kind of wheel blanks.
Background technology
In wheel manufacture process, wheel blanks end face is easily deformed, and main cause is uneven by mould cooling in wheel hub casting process, produces stress after blank solidification, and waveform deforms to cause surface to occur.Vehicle wheel side mould is generally made up of four pieces of Split molds, the analysis found that, two pieces of split limit mould intersections, and relative difference in height the most easily occurs in mould middle, monolithic limit.After wheel blanks hardening or heat treatment, each region deformation is inconsistent, and face deformation amount strengthens further.
Summary of the invention
It is desirable to provide a kind of wheel blanks reducing face deformation.
The technical scheme is that a kind of wheel blanks reducing face deformation, on blank after casting, two pieces of split limit mould intersections of blank wheel rim end face arrange separate slot, also blank after casting can arrange separate slot in the mould middle, monolithic limit of blank wheel rim end face, owing to vehicle wheel side mould is made up of four pieces of Split molds, therefore, the quantity that separate slot is arranged is 2,4,6,8.
The described separate slot degree of depth is 0.1 to 1 times of location wheel bilabial degree, and the lower limit of described separate slot upper end width is location wheel bilabial degree, and the upper limit is the 1/16 of wheel blanks girth, and the lower limit of residing separate slot lower end width is 0, and the upper limit is the 1/16 of wheel blanks girth.
Separate slot dispersibles the stress of cut-off part, reduces wheel blanks bulk deformation during stress deformation.Meanwhile, separate slot also can eliminate high point, reduces height difference in height.
Choose 18 cun, 20 cun, 22 cun 3 sections of wheel-type, 50 blanks of every money, by amendment mould of the present invention, under normal production, surveyed face deformation amount is obviously reduced relatively before after heat treatment, being reduced to 0.4,0.6,0.8 by original 1.0,1.3,1.5 respectively, reduction amount respectively reaches 0.6,0.7,0.7, and checking the method can obtain very good effect.
Accompanying drawing explanation
Fig. 1 is a kind of wheel blanks schematic diagram reducing face deformation of the present invention.
In figure: 1-separate slot.
Detailed description of the invention
Choosing 18 cun of wheel-type, on blank after casting, two pieces of split limit mould intersections of blank wheel rim end face arrange separate slot 1, and the quantity that separate slot 1 is arranged is 4.Described separate slot 1 degree of depth is 0.4 times of location wheel bilabial degree, and described separate slot 1 upper end width 4cm, residing separate slot 1 lower end width is 1cm.
Choosing 22 cun of wheel-type, on blank after casting, two pieces of split limit mould intersections of blank wheel rim end face arrange separate slot 1, and on blank after casting, the mould middle, monolithic limit of blank wheel rim end face arranges separate slot 1, and the quantity that separate slot 1 is arranged is 8.Described separate slot 1 degree of depth is 0.8 times of location wheel bilabial degree, and described separate slot 1 upper end width is 3cm, and lower end width is 2cm.
