Difference.R angles and other walk plucking, cracking at material and secretly split phenomenon, scrappage is high.
Utility model content
The purpose of this utility model is exactly to provide a kind of service life to overcome the defect of above-mentioned prior art presence
Long, safe and reliable, the lower-cost drawing die for inner plate of automobile rear wheel cover.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of drawing die for inner plate of automobile rear wheel cover, the mould include the die shoe being oppositely arranged and upper bolster,
The upper surface of described die shoe is provided with lower mould punch and is circumferentially positioned at lower mould punch periphery and vertically can lift
Flanging lifting platform, the lower surface of described upper bolster is provided with the upper mould die being adapted with lower mould punch.
Spring is provided between described flanging lifting platform and die shoe.
Bead is equipped with described flanging lifting platform and upper mould die.
Described flanging lifting platform is provided with blank holder, and the blank holder is arranged on the inner side of bead.
Multiple flanging boss are laid with described flanging lifting platform uniformly, described flanging boss is uniformly laid in flanging
The outside of circle.
Described flanging boss is arranged on the outside of bead.
Described blank holder and bead are processed using quenching technical.
Described blank holder is spliced using block insert type.
The lower die guiding being adapted with upper bolster is additionally provided with described die shoe to post.
R angles are additionally provided with described lower mould punch and upper mould die, and described R angles are processed using quenching technical.
Operation principle of the present utility model is：After tablet is put in mould, due to the effect of spring, flanging lifting platform liter
To highest point, tablet is sandwiched between upper bolster and flanging lifting platform；Press is depressed with specified pressure afterwards, flanging lifting platform
The upper surface of die shoe is depressed into downwards by upper bolster constantly, while tablet is gradually drawn between upper mould die and lower mould punch
Prolong；After drawing terminates, press is risen, take out part.
In the course of the work, flanging boss shifts to an earlier date one little groove of extrusion on tablet to this utility model, is conducive to control
The resistance that tablet processed is subject in drawing process, makes tablet more swimmingly flow between upper mould die and lower mould punch, from
And ensure that product surface quality.
Compared with prior art, this utility model has the characteristics that：
1) flanging boss is provided with flanging lifting platform, be conducive to controlling the resistance that tablet is subject in drawing process, carry
The mobility of high tablet, so that improve the quality of product；
2) Quenching Treatment technology is adopted at mould stress so as to which hardness and fineness are improved, reduce part and drawing
The probability of appearance such as occur plucking, cracking during prolonging, secretly split, wrinkle, so as to reduce the scrappage of part, improve part
The stability of production, while reducing the normal wear speed of mould, extends the mold use life-span；
3) blank holder is spliced using block insert type, be easy to maintenance, and due to hardness improve reduce mould plucking and
The probability of normal wear, reduces the number of times and cost of maintenance.
