Abstract
It the utility model is related to a kind of high euphotic belt shearing progressive die, including upper die and lower die, the pre-cut mould and finish module of stamping products are sequentially provided between the upper die and lower die from feedstock direction toward processing direction, the pre-cut mould includes mould in the pre-cut that is connected on upper die and lower die and cuts mould in advance, the pre- mould that cuts is externally provided with the triangle boss around trimming in trimming, boss can be completely covered when under being molded in the pre-cut, the finish module includes the fine cut punch-pin and fine cut cavity plate that branch is connected on upper die and lower die, blade clearance between the fine cut punch-pin and fine cut cavity plate is thick for unilateral 0.1 times material, to solve the problems, such as that the trimming when high euphotic belt is sheared of existing progressive die has turned-down edge and fold.
Description
Technical field
Technical field of mold is the utility model is related to, is specifically related to a kind of high euphotic belt shearing progressive die.
Background technology
Diel is that the equipment that pressure processing uses is carried out to material, and its work original is the effect by mould in punching press
The folding of mould and lower mould in lower drive and the raw material between it are cut, punching, stretching etc. are shaped to form stamping parts.Punching
The more and more extensive every field for being applied to production, living of die casting/processing part, therefore shape of product becomes increasingly complex, outside product
See and size requires also more and more higher.For stamping products, if having shear surface euphotic belt requirement on product, mould is usual
Way is to reduce blade clearance so that shear surface reaches bright requirement, but such effect of doing is unsatisfactory, and can be to trimming portion
Divide and cause turned-down edge, the especially trim portion in arc, can also there is the problem of fold.
Utility model content
The utility model aims to provide a kind of high euphotic belt shearing progressive die, to solve existing progressive die in high euphotic belt
During shearing there is the problem of turned-down edge and fold in trimming.
Concrete scheme is as follows：
A kind of high euphotic belt shearing progressive die, including upper die and lower die, it is past from feedstock direction between the upper die and lower die
Processing direction is sequentially provided with the pre-cut mould and finish module of stamping products, and the pre-cut mould includes being connected on upper die and lower die
Pre-cut on mould and it is pre- cut mould, the pre- mould that cuts is externally provided with the triangle boss around trimming in trimming, in the pre-cut
Boss can be completely covered when under molding, the finish module includes fine cut punch-pin and the essence that branch is connected on upper die and lower die
Cavity plate is cut, the blade clearance between the fine cut punch-pin and fine cut cavity plate is thick for 0.1 times of negative material.
Preferably, the vertical range of the summit of the boss and trimming is that 0.2 times of material is thick.
Preferably, on the linear type in summit that trimming is the boss at linear pattern, the top in trimming for the boss at arc
Point is in sawtooth pattern.
Preferably, it is that 0.4 times of material is thick in the height that trimming is the boss at linear pattern, is the boss at arc in trimming
The height of highest point is that 0.5 times of material is thick, thick for 0.3 times of material in the height of lowest part.
A kind of high euphotic belt shearing progressive die provided by the utility model has advantages below compared with prior art：This
A kind of high euphotic belt that utility model provides shears progressive die when stamping products are by pre-cut mould, and boss makes the bottom of stamping products
Face forms the notch of triangle, and when by finish module, notch can avoid stretching during because of punching from causing trimming turned-down edge,
The boss in arc trimming is in sawtooth pattern in addition, therefore in fine cut, because squeezing when notch highly straggly can avoid being punched
Fold caused by pressure, mode is pushed using small―gap suture between fine cut punch-pin and fine cut cavity plate, forms the processing work of big euphotic belt
Part, the influence that the high euphotic belt caused by the turned-down edge caused by conventional ones and fold is unsatisfactory for requiring is avoided, is substantially improved
The outward appearance of product, improve the qualification rate of product.
Brief description of the drawings
Fig. 1 shows the schematic diagram of high euphotic belt shearing progressive die.
Fig. 2 shows the partial schematic diagram of pre-cut mould.
Fig. 3 shows the schematic diagram of finish module.
Fig. 4 shows the partial schematic diagram of boss.
Embodiment
To further illustrate each embodiment, the utility model is provided with accompanying drawing.These accompanying drawings are in the utility model discloses
A part for appearance, it can coordinate the associated description of specification to explain the running of embodiment original mainly to illustrate embodiment
Reason.Cooperation refers to these contents, and those of ordinary skill in the art will be understood that other possible embodiments and this practicality are new
The advantages of type.Component in figure is not necessarily to scale, and similar element numbers are conventionally used to indicate similar component.
The utility model is further illustrated in conjunction with the drawings and specific embodiments.
As shown in Figure 1-Figure 3, a kind of high euphotic belt shearing progressive die provided by the utility model, including upper mould 1 and lower mould
2, the pre-cut mould 3 and finish module 4 of stamping products 5 are sequentially provided between the upper die and lower die from feedstock direction toward processing direction,
The pre-cut mould 3 include in the pre-cut that is connected on upper die and lower die mould 30 and it is pre- cut mould 32, it is described pre- to cut mould 32
The triangle boss 320 around trimming 50 is externally provided with trimming, boss 320 can be covered completely when mould 30 is depressed in the pre-cut
Lid, so that boss 320 forms the bottom of stamping products 5 in the notch 52 of one triangle.The finish module 4 includes dividing
Portion is connected to fine cut punch-pin 40 and fine cut cavity plate 42 on upper die and lower die, the punching between the fine cut punch-pin and fine cut cavity plate
Gap is that unilateral 0.1 times material is thick, as the 0.1 of stamping products thickness times.When stamping products are by pre-cut mould, boss produces punching press
The bottom surface of product forms the notch of triangle, and when by finish module, notch can avoid stretching during because of punching from causing to cut
Side turned-down edge, the outward appearance of product is substantially improved, improve the qualification rate of product.
With reference to figure 2, as a preferred scheme of boss, the summit of the boss and the vertical range L of trimming are 0.2
Thickness is expected again, and the summit of boss and the vertical range of trimming are thick this part that can have more trimming of 0.2 times of material in finish module
High euphotic belt is preferably formed when punching press, and the precision of finished product being punched out can be ensured.
It is linear on the summit that trimming is the boss at linear pattern as another preferred scheme of boss with reference to figure 4
Type, it is in sawtooth pattern on the summit that trimming is the boss at arc.Boss in arc trimming is in sawtooth pattern, therefore in fine cut,
Notch highly straggly can avoid punching when caused by extruding fold, it is still high euphotic belt to ensure trimming.Preferably, exist
Trimming is that the height of 320a boss at linear pattern is that 0.4 times of material is thick, in the highest point that trimming is 320bb boss at arc
Height it is thick for 0.5 times of material, thick for 0.3 times of material in the height of lowest part, these sizes can enable trimming preferably to be formed
High euphotic belt.
Although specifically showing and describing the utility model with reference to preferred embodiment, those skilled in the art should
This is understood, is not departing from the spirit and scope of the present utility model that appended claims are limited, in form and details
On the utility model can be made a variety of changes, be the scope of protection of the utility model.
