Description
Technical field
The utility model is related to a kind of hole flanging mold, especially a kind of hole flanging mold of anti-hole flanging cracking.
Background technology
At present when the structure of mould hole flanging is designed, the relation of hole flanging height and hole flanging diameter is seldom considered, all use
Single hole flanging structure, because hole flanging is too high, there is drawing crack or secretly splits in hole flanging edge that is making product for Jing often appearance, and hole flanging
There is zigzag, the outward appearance of impact product in plane, and reduces the intensity of hole flanging, affects the quality of product.
Traditional turnup structure is also present. and hole flanging is at present in mould without supporting, and material flow deformation is very fast, high-strength when meeting
Cracking, and top surface out-of-flatness are easy to during degree material；Quick-replaceable and can not repair a die on punch press during production abrasion, will be whole
Could change after individual mould release, the time is long；Flange drift is integral type, must all be scrapped if abrasion, again again
Do new, the cycle is longer, high cost.
Utility model content
To solve the above problems, the utility model will not ftracture or produce and secretly split when providing a kind of hole flanging, outward appearance it is good one
The hole flanging mold of anti-hole flanging cracking is planted, concrete technical scheme is：
A kind of hole flanging mold of anti-hole flanging cracking, including holding pad, keel, flange drift, flange drift mold insert, flange
Die, stripper plate mold insert and stripper plate；The keel, flange drift and flange drift mold insert are sequentially connected, the keel
It is fixed on upper bolster；The holding pad is located at upper bolster lower section, and is connected with upper bolster by upper mould nitrogen spring；It is described to turn over
Edge die is fixed on die shoe, and the flanging bore of flange die is through hole, and, the lower mould concentric with the spring eye of die shoe
Nitrogen spring is arranged in the spring eye of die shoe, and the stripper plate is fixed on lower mould nitrogen spring, the stripper plate mold insert
It is fixed on stripper plate, the stripper plate mold insert and stripper plate are respectively positioned in the flanging bore of die.
The bottom of the flange drift mold insert is provided with fore-set, and the diameter of the fore-set is less than the diameter of hole flanging bottom outlet, fore-set
Top is provided with mold insert inclined-plane；Fore-set shoulder hole is provided with the top of the fore-set, the fore-set shoulder hole is through hole.
The bottom of the flange drift is provided with hole flanging inclined-plane, the hole flanging inclined-plane and mold insert slopes which match；The flange
The bottom of drift is additionally provided with punch pin through-bores.

The mold insert boss is inserted in mold insert boss groove.
Drift boss is provided with the top of the flange drift, the bottom of the keel is provided with drift boss groove, the punching
Head boss is inserted in drift boss groove；The bottom of the drift boss groove is provided with screwed hole.
The stripper plate mold insert top is provided with embedding piece groove, and the flange drift 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 external diameter, this mould is suitable for.
Keel supports flange drift, and flange drift is positioned, and by tight fit the position of flange drift is limited.
Flange drift is to material crimp up to the hole flanging shape to want to design.
Flange drift mold insert serves the effect on a pre- top, first contacts with lower mould inner stripper mold insert, the lower mould nitrogen of balance
The power of gas spring, prevents the mould nitrogen spring under the shaping initial stage that the deformation of material top is unable to reach the Expected Results of hole flanging.
Stripper plate mold insert is consistent with flange drift insert shape, between have the gap of a thickness of slab.Stripper plate mold insert with turn over
Side drift mold insert makes to push down plate during hole flanging all the time, prevents cracking, makes top surface smooth.
During debugging, it is only necessary to which the diameter of flange drift is made into conversion and modification can just adjust the height of hole flanging, and padded
Block and flange drift mold insert need not be changed, and save the cost and time for changing mould.
When there is abrasion in flange drift to be needed to change, can be in the case where holding pad not be torn open directly by flange drift edge
Part change, instantly the stripper plate mold insert of mould occur abrasion need replacing when, directly can tear open from above lower mould inner stripper
Under, so that mold repair is very simple and direct, convenient, when can save to greatest extent when product mass production
Between, improve production efficiency！
The hole flanging mold simple structure of a kind of anti-hole flanging cracking that the utility model is provided, engaged position are little, processing, maintenance
It is convenient, improve production efficiency and security, while hole flanging intensity it is high, without ftractureing or secretly splitting, surface is smooth, without zigzag.
