Embodiment
Referring to figs. 1 to Fig. 6, a kind of stamping head of stamping die fastening structure, including set gradually from top to bottom cope plate 1,
Backing plate 2 and punch fixing plate 3, punch fixing plate 3 is forged using 40Cr materials and is made, after the conditioned heat treatment of 40Cr materials
Good low-temperature impact toughness, it is excellent die steel with good comprehensive mechanical property.It is provided with punch fixing plate 3
For fixing the abnormal-shaped punch fixing hole of drift 4, punch fixing plate 3 and backing plate 2 pass through a plurality of positioning to be overlapping rectangular-shaped
Pin 11 and connecting bolt 12 connect as one, and are then integrally attached to the downside of cope plate 1.Drift 4 is fixed on drift and fixed
In hole, during work, cope plate 1 is descending, and drift 4 is pressed on the sheet material placed on cavity plate, and the sheet material of contact portion is pressed into cavity plate,
So as to obtain the product of abnormity.
It is uniform successively along its length on punch fixing plate 3 to be provided with four insertions and up-narrow and down-wide conical bore, punching
Head fixing hole is divided into multigroup, and an each group of corresponding conical bore, each group of drift fixing hole includes two sections of conical bores two that are placed in
The drift of side, which is fixed, divides hole.Load one group of drift 4 in each group of drift fixing hole, each group of drift 4 include two respectively with punching
The fixed drift for dividing hole the to be adapted to segmentation of head.
Each drift fixes point hole and penetrates punch fixing plate 3, and gap 9 connects together between conical bore for it, seam
Part of the drift fixation point between hole and conical bore is divided into two by gap 9, turns into the elastic pressing part 10 of plastically deformable.In conical bore
The locking cone post 5 being adapted to therewith is inserted, the path of locking cone post 5 is more than the path of conical bore, and its top surface is provided with screwed hole 6, pads
The dormant bolt hole of corresponding screwed hole 6 is provided with plate 2, dormant bolt hole is built with the locking stud 7 being adapted to screwed hole.Pass through
Locking cone post 6 is locked in conical bore by locking stud 7, and locking cone post 6 is oppressed elastic pressing part 10 and deformed laterally, and elastic pressing part 10 will
Drift segmentation being locked only that drift is fixed in point hole.Locking cone post 5 is used as driving element, its material selection Cr12 moulds
Have steel, and be heat-treated to HRC58 ° -60 °, thus ensured that it has high-wearing feature, it is ensured that worn during Reusability it is small, with
Just service life is improved.
By drift segmentation, drift fixation divides in hole corresponding to insertion respectively during assembling, is connect in the upper surface for confirming drift segmentation
Place into locking cone post 5 after contacting backing plate 2, due to locking cone post 5 end diameter be more than punch fixing plate 3 on conical bore it is small
Hold diameter, the small end face of tight fastening cones 5 is hanging when locking fastening cones 5 by locking stud 7, not with the downside of backing plate 2
Face contacts, and after fastening cones 5 is locked, compels compaction forces by scalene cone transmission, divides using cartridge clip principle, while by the drift of both sides
Section is pressed on drift and fixed in point hole, and the i.e. detachable punching head segmentation of locking stud 7 need to be only unscrewed during dismounting.Such drift fastening
Structure, it is very useful for special-shaped tiny drift, effectively solve the deficiency of conventional fixed structure, quickly and easily to fill
Match somebody with somebody or change drift, substantially increase production efficiency.
The elastic hole 8 in corresponding dormant bolt hole is also provided with cope plate 1, the internal diameter in elastic hole 8 is more than the big of locking stud 7
Head diameter, such structure easily can retract and fasten drift, directly from the upside tool operation of cope plate 1, nothing
Backing plate 2 and punch fixing plate 3 need to be disassembled, so as to save the drift lay day, improve operating efficiency.
A cut-out drift 13 is further fixed on the punch fixing plate 3 of described four groups of drifts 4 one end, its both sides is set to diameter
Semicircle groove corresponding with pressing sheet material width.Each drift segmentation corresponds to the different sections of stamping products polymorphic structure respectively, often
One group of drift 4 includes two drifts and is segmented, and totally eight drifts are segmented respectively stamping products from different directions to four groups of drifts.Work
When, sheet material is with the step-type feeding of length of the two neighboring distance of locking cone post 5, and first product is first by one group of punching of high order end
The molded Part I of primary drying, then to the right step feeding once and by from left to right second group of punch connection Part I
Part II, by that analogy, finally by the 4th group of punch decline, so as to obtain complete special-shaped product structure,
The product that punching press is completed continues stepping to the right, then by the cut-out drift 13 of end by product separating one by one, subsequently
Product gradation punching press successively, whole process are automatically performed, it is achieved thereby that drift is smaller and punching press that product structure is complicated.
It is described above, simply better embodiment of the present utility model, but the utility model is not limited to above-described embodiment,
As long as it reaches technique effect of the present utility model with any same or similar means, protection of the present utility model should be all included in
Within the scope of.
