Description
Technical field
The present invention relates to stamping technology field, in particular to a kind of small size thickness material stamping continuous die and presser
Skill.
Background technique
As China's stamping technology constantly develops, automobile market competitive pressure continues to increase, the zero of many foreign countries' imports
Part will domesticize.
It is the ratchet button 1 on a safety chair seats of car shown in Fig. 1, the material with 4.0mm is thick, but most narrow place 11 only has
0.88mm requires the angle of collapsing of product to be no more than the 10% of material thickness, and wet look will be more than thick 85% or more of material.Using common
Sheet Metal Forming Technology is exactly that punch structure and product shape are completely the same, can 0.88mm width formed punch under huge reaction force very
Be easy to thrust, angle of collapsing is excessive and the too small problem of wet look also frequent occurrence, it is difficult to reach customer requirement.
Summary of the invention
The main purpose of the present invention is to provide a kind of small size thickness material stamping continuous die and Sheet Metal Forming Technologies, being capable of high quality
The punch forming of ground completion small size thickness material.
The present invention is achieved through the following technical solutions above-mentioned purpose:
A kind of small size thickness material progressive die cuts positioning casement, adjustment blanking die, ironed mould and blanking including what is set gradually
Mould, the adjustment blanking die include adjustment formed punch, and projected outline's opposing product standard shape of the adjustment formed punch deviates outward,
The ironed mould includes the cavity plate of corresponding product standard shape and the ironed formed punch of projection covering cavity plate and adjustment region.
Specifically, projected outline's relative standard's shape of the adjustment formed punch deviates 0.5-2mm outward.
Specifically, the adjustment blanking die includes two adjustment formed punches for being used to hemisection.
A kind of small size thickness material Sheet Metal Forming Technology, step include:
1. cutting location hole: cutting out location hole on material strip；
2. adjustment punching: on the basis of location hole, the narrow discharge position of product profile adjusted is cut out on material strip, and adjust
Whole profile relative standard shape deviates outward；
3. ironed: using ironed formed punch by the cavity plate of material indentation jointing product standard shape, material being made to become product
There is the structure of featheredge around narrow discharge position and is connected on material strip；
4. blanking: being cut product from material strip along standard shape with blanking die.
Further, the step 2. in, hemisection completion that adjustment position be overlapped by position twice.
Specifically, the projection covering step of the ironed formed punch 2. in adjustment region.
By adopting the above technical scheme, the beneficial effect of technical solution of the present invention is:
This technique by adjusting punching allow deformed part can be secured be connected on material strip, prevent from thrusting, then press again
Thin to form the featheredge for being easy to cut, blanking die is just not easy to thrust when such blanking, and the angle that also avoids collapsing is big and bright
The small problem in face.

Specific embodiment
Invention is further described in detail combined with specific embodiments below.
Embodiment:
As depicted in figs. 1 and 2, a kind of small size thickness material Sheet Metal Forming Technology of the invention, step include:
1. cutting location hole: cutting out location hole on material strip 2 with positioning hole portion is cut, can actually generate positioned at 2 side of material strip
First positioning hole 21a and second location hole 21b positioned at 2 other side of material strip, mold positioned with first positioning hole 21a and second
Material strip 2 is subjected to stepping conveying on the basis of the 21b of hole.
2. adjustment punching: on the basis of location hole, cutting out the narrow discharge position of product on material strip 2 with adjustment punching portion and adjust
Profile afterwards, and adjust profile relative standard shape and deviate outward.The narrow discharge position of product corresponds to the most narrow place 11 of ratchet button 1,
The standard shape of ratchet button 1 corresponds to 24 range of feeding zone.The purpose of punching of adjusting is that narrow discharge position is prevented to be thrust.
3. ironed: being pressed into material using ironed formed punch 32 (the ironed area 23b that corresponding diagram 2 beats oblique line) in ironed mould and be bonded
In the cavity plate 31 (the cavity plate area 23a that corresponding diagram 2 beats cross) of product standard shape, material is made to become to have around the narrow discharge position of product
The structure of featheredge 23c is simultaneously connected on material strip.Ironed is to allow the center of material strip 2 to squeeze into formation ratchet button 1 in cavity plate
Shape, and adjust in punching the Offset portion that stays and just squeezed flat at featheredge 23c, and material by ironed formed punch 32 and cavity plate 31
Useful part can also be connected on material strip 2 by featheredge 23c, continue to send to blanking.
4. blanking: being cut product from material strip 2 along standard shape with blanking die (corresponding feeding zone 24) in blanking portion
Under.Blanking die only needs to thrust featheredge 23c at this time, because of the thickness of featheredge 23c still very little, in blanking punching
The reaction force thrust in the case that head part is very thin is little, this also just protects blanking die.
As shown in Fig. 2, 2. middle blank profile relative standard's shape deviates 0.5-2mm to step outward.This range can allow narrow
Material position is equipped with enough intensity and is connected on material strip 2, and ironed step is facilitated to flatten this pocket.
As shown in Fig. 2, step 2. in, the hemisection that the narrow discharge position of product is overlapped by position twice is completed.The narrow discharge position of product
Peninsular structure, one-step punching may be allowed because of getting stuck de- material when malformation, first cut out first by hemisection twice
Then hemisection area 22a cuts out the second hemisection area 22b overlapped again, can thus form peninsular structure to be achieved, really
Protect Product Precision.
As shown in Fig. 2, step 3. in, the projection of ironed formed punch 32 (corresponding ironed area 23b) covering step 2. in narrow material
Position magnification region.This structure of ironed formed punch 32 is the rigidity in order to promote itself, prevents ironed reaction force from making to press
Thin formed punch 32 breaks.
Above-described is only some embodiments of the present invention.For those of ordinary skill in the art, not
Under the premise of being detached from the invention design, various modifications and improvements can be made, these belong to protection model of the invention
It encloses.
