Abstract
The invention relates to a drawing die for inner plates of rear wheel covers of automobiles. The die comprises an upper die holder and a lower die holder which are arranged oppositely, wherein a lower die male die and an edge pressing lifting platform which surrounds the periphery of the lower die male die and can rise and fall vertically are arranged on the upper surface of the lower die holder; and an upper die female die fit with the lower die male die is arranged on the lower surface of the upper die holder. Compared with the prior art, the drawing die has the advantages as follows: edge pressing bosses are arranged on the edge pressing lifting platform, control on resistance on laminates in the drawing process is facilitated, the product quality is improved, the quenching treatment technology is adopted in stressed positions of the die, probability of galling, cracking, hidden cracking, wrinkling and the like in the drawing process of parts is reduced, and the service life of the die is prolonged.
Description
Technical field
The invention belongs to automobile part production technique field, relate to a kind of drawing die for inner plate of automobile rear wheel cover
Tool.
Background technology
At present, the drawing die upper mold of inner plate of automobile rear wheel cover part all be double dynamic compressors, Making mold requirement
The highest, and manufacture process is more complicated, the manufacturing cycle is long, high to using equipment requirements, keeps in repair loaded down with trivial details, uses
Equipment compatibility is poor.R angle and other walk easily to occur at material plucking, cracking and secretly split phenomenon, scrappage is high.
Summary of the invention
Defect that the purpose of the present invention is contemplated to overcome above-mentioned prior art to exist and provide a kind of service life length,
Drawing die for inner plate of automobile rear wheel cover safe and reliable, lower-cost.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of drawing die for inner plate of automobile rear wheel cover, this mould includes die shoe and the upper mold being oppositely arranged
Seat, the upper surface of described die shoe is provided with lower mold punch and to be circumferentially positioned at lower mold punch peripheral and can be along vertically
The flanging lifting platform of direction lifting, it is recessed that the lower surface of described upper bolster is provided with the upper mold suitable with lower mold punch
Mould.
It is provided with spring between described flanging lifting platform and die shoe.
It is equipped with bead on described flanging lifting platform and upper mold die.
Described flanging lifting platform is provided with blank holder, and this blank holder is arranged on the inner side of bead.
Uniformly being laid with multiple flanging boss on described flanging lifting platform, described flanging boss is uniformly laid in pressure
The outside of flange.
Described flanging boss is arranged on the outside of bead.
Described blank holder and bead all use quenching technical to process.
Described blank holder uses block insert type to be spliced.
The lower mold lead suitable with upper bolster it is additionally provided with on described die shoe.
Being additionally provided with R angle on described lower mold punch and upper mold die, described R angle uses at quenching technical
Reason.
The operation principle of the present invention is: after being put in mould by tablet, due to the effect of spring, flanging lifting platform liter
To highest point, tablet is sandwiched between upper bolster and flanging lifting platform；Press specified pressure pressure, pressure afterwards
Limit lifting platform is constantly depressed into downwards the upper surface of die shoe by upper bolster, and tablet is gradually in upper mold die and lower mold simultaneously
By drawing between punch；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 the present invention, is conducive to controlling
The resistance that tablet is subject in drawing process, makes tablet flow more swimmingly between upper mold die and lower mold punch
Dynamic, thus ensure that product surface quality.
Compared with prior art, the invention have the characteristics that:
1) it is provided with flanging boss on flanging lifting platform, is conducive to controlling the resistance that tablet is subject in drawing process,
Improve the mobility of tablet, thus improve the quality of product；
2) Quenching Treatment technology is used at mould stress so that it is hardness and fineness are improved, and reduce part
Drawing process occurs plucking, cracking, secretly split, the probability of the appearance such as wrinkling, thus reduce scrapping of part
Rate, improves the stability that part produces, reduces the normal wear speed of mould simultaneously, extend making of mould
Use the life-span；
3) blank holder uses block insert type to be spliced, it is simple to maintenance, and decreases mould plucking and just owing to hardness improves
Often the probability of abrasion, reduces number of times and the cost of maintenance.

Detailed description of the invention
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with the technology of the present invention side
Implement premised on case, give detailed embodiment and concrete operating process, but the protection model of the present invention
Enclose and be not limited to following embodiment.
Embodiment 1:
A kind of drawing die for inner plate of automobile rear wheel cover as Figure 1-3, this mould includes being oppositely arranged
Die shoe 1 and upper bolster 2, the upper surface of die shoe 1 is provided with lower mold punch 3 and is circumferentially positioned at lower mold punch
3 peripheries and the flanging lifting platform 9 that can vertically lift, the lower surface of upper bolster 2 is provided with and lower mold punch 3
Suitable upper mold die 4.It is provided with spring between flanging lifting platform 9 and die shoe 1.Flanging lifting platform 9 and on
Bead 6 it is equipped with on mould die 4.Flanging lifting platform 9 is provided with blank holder 7, and this blank holder 7 is arranged on and draws
Prolong the inner side of muscle 6.Uniformly it is laid with 8 flanging boss 8 on flanging lifting platform 9, and 8 flanging boss 8 are equal
