Description
Technical field
The present invention relates to a kind of hole flanging mold, especially a kind of hole flanging mold of anti-hole flanging cracking.
Background technology
At present when designing the structure of mould hole flanging, seldom consider hole flanging height and the relation of hole flanging diameter, all use
Single hole flanging structure, often occurs making the hole flanging edge of product drawing crack occur or secretly split because hole flanging is too high, and hole flanging
There is zigzag in plane, influences the appearance of product, and reduces the intensity of hole flanging, influences the quality of product.
For traditional turnup structure also there are not supported in lower die during hole flangings, material flow deformation is very fast, high-strength when meeting
It is easy to crack when spending material, and top surface out-of-flatness；Quick-replaceable and it cannot repair a die on punching machine during production abrasion, will be whole
It could be replaced after a mould release, time length；Flange punch is integral type, must all be scrapped if abrasion, again again
Do new, the cycle is longer, of high cost.
The content of the invention
Secretly split to solve the above problems, the present invention will not cracking or produce when providing a kind of hole flanging, the good one kind of appearance is prevented
The hole flanging mold of hole flanging cracking, concrete technical scheme are：
A kind of hole flanging mold of anti-hole flanging cracking, including holding pad, keel, flange punch, flange punch mold insert, flange are recessed
Mould, stripper plate mold insert and stripper plate；The keel, flange punch and flange punch mold insert are sequentially connected, and the keel is consolidated
It is scheduled on upper mold seat；The holding pad is located at below upper mold seat, and is connected by upper mold nitrogen gas spring with upper mold seat；The flange
Cavity plate is fixed on die holder, and the flanging bore of flange cavity plate is through hole, and concentric with the spring eye of die holder, the lower die nitrogen
Gas spring is installed in the spring eye of die holder, and the stripper plate is fixed on lower die nitrogen gas spring, and the stripper plate mold insert is consolidated
It is scheduled on stripper plate, the stripper plate mold insert and stripper plate are respectively positioned in the flanging bore of cavity plate.
The bottom of the flange punch mold insert is equipped with fore-set, and the diameter of the fore-set is less than the diameter of hole flanging bottom outlet, fore-set
Top is equipped with mold insert inclined-plane；The top of the fore-set is equipped with fore-set stepped hole, and the fore-set stepped hole is through hole.
The bottom of the flange punch is equipped with hole flanging inclined-plane, the hole flanging inclined-plane and mold insert slopes which match；The flange
The bottom of punch is additionally provided with punch pin through-bores.
The top of the flange punch mold insert is equipped with mold insert boss, and the bottom of the flange punch is equipped with mold insert boss groove,
The mold insert boss is inserted in mold insert boss groove.
The top of the flange punch is equipped with punch boss, and the bottom of the keel is equipped with punch boss groove, the punching
Head boss is inserted in punch boss groove；The bottom of the punch boss groove is equipped with threaded hole.
Embedding piece groove is equipped with the top of the stripper plate mold insert, the flange punch mold insert is located in embedding piece groove.
Work as flange height（Without thickness of slab）When being more than 0.1 with the ratio of hole flanging outside diameter, this mould is applicable in.
Keel supports flange punch, and flange punch is positioned, and the position of flange punch is limited by tight fit.
Flange punch reaches material crimp the hole flanging shape to want to design.
Flange punch mold insert plays the role of one and pushes up in advance, is first contacted with lower die inner stripper mold insert, balances lower die nitrogen
The power of gas spring, prevents from being unable to reach the deformation of material top in shaping lower die nitrogen gas spring at initial stage the Expected Results of hole flanging.
Stripper plate mold insert is consistent with flange punch insert shape, between have the gap of a thickness of slab.Stripper plate mold insert is with turning over
Side punch mold insert makes to push down plate all the time during hole flanging, prevents from cracking, makes top surface smooth.
During debugging, it is only necessary to the diameter of flange punch is made into conversion and changes the height with regard to hole flanging can be adjusted, and it is padded
Block and flange punch mold insert need not be changed, and save the cost for changing mould and time.
When abrasion, which occurs, in flange punch to be needed replacing, directly flange punch can be inlayed in the case where not tearing holding pad open
Part is replaced, and when abrasion, which occurs, in the stripper plate mold insert of lower die to be needed replacing, can directly be torn open above lower die inner stripper
Under, so that mold repair is very simple and direct, convenient, when can be saved to greatest extent when product mass production
Between, improve production efficiency.
The hole flanging mold of anti-hole flanging cracking provided by the invention a kind of is simple in structure, engaged position is small, processing, easy to maintain, carries
High efficiency and security, while hole flanging intensity is high, splits without cracking or secretly, surface is smooth, no zigzag.
