Specific implementation mode
The embodiments described below with reference to the accompanying drawings are exemplary, is only used for explaining the present invention, and cannot be construed to
Limitation of the present invention.
As shown in Fig. 1 to 5, the embodiment provides a kind of hollow stamping parts drawing methods, including：
Step 1：By blanking and punching mold, the hole being sized will be gone out among block, mesoporous waste material can be used for it
His stamping parts production programming is conducive to the promotion of vehicle stock utilization, to obtain hollow material 17 for follow-up drawing, this step
Used in blanking and punching mold can be selected the prior art structure, to without repeat purchase or be transformed, saving is produced into
This.
Step 2：Draw forming is carried out to hollow material 17 obtained by step 1 using drawing die, to ensure that hollow material 17 is drawn
Prolonging formability and avoids drawing defect, drawing die used in this step is special die, using inside and outside binder technological design,
Intermediate draw forming ensures product rigidity and solves forming defects.
The present embodiment additionally provides a kind of drawing die, the step of for above-mentioned hollow stamping parts drawing work method
In two, including upper die holder 1, lower die holder 2 and the first blank holder 3 on the lower die holder 2 and fission_typed punch 4, it is described
Fission_typed punch 4 is fixed in first blank holder 3, and the fission_typed punch 4 is equipped with the cavity of upper opening to be formed back
Type structure is provided with the second blank holder 5 in the cavity.
Specific work process：Manipulator places hollow material 17 on first blank holder 3 and the second blank holder 5, at this time lathe
The dead block of ejector pin contact pier realizes that the first blank holder 3 and the second blank holder 5 jack up retainer.1 downlink of upper die holder, then the first flanging
3 pairs of 17 outer boundary borders of hollow material of circle carry out binder, and at the same time upper die holder 1 also contacts the second blank holder 5 and starts to hollow material
17 inner boundaries carry out binder, until molding.Then by the first blank holder 3 it is synchronous with the second blank holder 5 to drawing operation part into
Row discharging, mandril jacks up the first blank holder 3 and the second blank holder 5 forces drawing operation part far from fission_typed punch 4, and realization is unloaded
Material avoids deforming caused by only having the 3 outer ring binder surface progress discharging of the first blank holder easily to intermediate region；The drawing work method
And mold realizes that hollow space tablet utilizes, improves product stock utilization, while solving drawing and being easy out by hollow material 17
Split, add puncture be easy to cause produce unstable, the problem of the bad row of postorder hollow space deburring waste material, effectively improve production effect
Rate reduces assembling and setting difficulty and complex degree of structure.
Specifically, first blank holder 3 is hollow structure, the Internal periphery of first blank holder 3 and described split type
The outer profile of punch-pin 4 is adapted, and the side of first blank holder 3 is horizontally outward extended with the first guide plate 6, the lower die respectively
It is corresponding on seat 2 to be equipped with and the guide plate matched first slide guide face 7；Second blank holder 5 is rectangular box structure, rectangle
It is additionally provided with multiple shock relieve vents in box body structure, to reduce quality, reduces cost, the outer profile of second blank holder 5 and described
The Internal periphery of fission_typed punch 4 is adapted, and the side of second blank holder 5 is horizontally outward extended with the second guide plate 8, institute respectively
State fission_typed punch 4 inner wall it is corresponding be equipped with the guide plate matched second slide guide face 9, to formed drawing punch forming
Motion guide, until molding.
In order to avoid mistake is arranged because of lathe lift rod stroke, the first blank holder 3 and the second blank holder 5 are pushed up and flown, causes to pacify
Full hidden danger；First blank holder 3 and second blank holder 5 are equipped with safety travel caging bolt 10, multiple safety
Stroke limit bolt 10 is inverted to be connected with first blank holder 3 and second blank holder 5 respectively after the lower die holder 2
It connects, safe spacing distance is preset in 10 head of safety travel caging bolt away from 2 working face of lower die holder.Wherein, security row degree
The safe spacing distance of position bolt 10 is the impulse stroke+20mm safe doses of the first blank holder 3 and the second blank holder 5.
The lower die holder 2 is circumferentially provided with protective plate 11, is bolted on lower die holder 2, and entire protective plate 11 is right
Mandril working region is protected, avoid because lathe mandril power greatly caused by attachment capping splash, cause security risk.
Annular is provided with multiple locating pieces on the first blank holder 3, and in the present embodiment, locating piece includes conventional positioning plate 12
And induction positioning plate 13, the cooperation induction positioning plate 13 of conventional positioning plate 12 make horizontal direction position so that plate is smooth to be placed on
On first blank holder 3.In actual use, it can increase and decrease and arrange locating piece according to actual conditions.
In order to balance blank holder pressure-plate-force, on first blank holder 3 and second blank holder 5 annular be evenly equipped with it is more
A balance weight 14, the upper die holder 1 are equipped with and 14 matched driving platform 15 of the balance weight.
For the transport and operation of more convenient die holder 2 up and down, transportational process is avoided to connect upper and lower mould transportational process because of transport
Vehicle emergency stop or inertia cause mold moving, cause mold damage and security risk.The opposite sides of the lower die holder 2 is arranged with
Multiple transport connecting plates 16.
The structure, feature and effect of the present invention, the above institute are described in detail based on the embodiments shown in the drawings
Only presently preferred embodiments of the present invention is stated, but the present invention is not to limit practical range, every structure according to the present invention shown in drawing
