Specific embodiment
Now in conjunction with the drawings and specific embodiments, the present invention will be further described.
As shown in Figures 1 to 3, a kind of new-energy automobile carbon brush holder insulating part stamping die may include upper die component 1 and lower die
Component 2.Wherein, upper die component 1 may include that the panel 11 being sequentially arranged from top to bottom, thimble push plate 12, ejector retainner plate 13, red needle are solid
Fixed board 14, concave template 15, interior de- plate 16 and other attachmentes (such as red needle 17).The assembling mode of upper die component 1 is this field skill
Known to art personnel, it is not further described herein.
Wherein, the shape of interior de- plate 16 corresponds to the shape of molding carbon brush holder insulating part to be punched and is distributed with thereon
Red needle hole 161a, 161b, 161c, 161d, 161e corresponding with the through-hole on the carbon brush holder insulating part.The formed punch shape of red needle 17
Shape is corresponding with red needle hole 161a, 161b, 161c, 161d, 161e.161a, 161b, 161c, 161d, 161e include great circle in red needle hole
Shape red needle hole 161a, middle round red needle hole 161b, small circular red needle hole 161c, D-shaped red needle hole 161d and special-shaped red needle hole 161e.
The outer peripheral edge of interior de- plate 16 and the peripheral wall of red needle hole 161a, 161b, 161c, 161d, 161e are equipped with several chip spaces 162, this
So that the chip removal ability of red needle formed punch greatly enhances.It is equipped among concave template 15 and the consistent opening 151 of the shape of interior de- plate 16.
Therefore, interior de- plate 16 can pass through concave template 15.The peripheral wall of the opening 151 of concave template 15 is equipped with several gas holes 152.Institute
Show in embodiment, the quantity of the gas hole 152 is 4, is separated from each other 90 °.Gas hole 152 can external tracheae (do not show
Out), when interior de- plate 16 is to bottom knockout, blowing enters concave template 15 and blows down the product for being attached to interior de- plate 16, and will be intracavitary residual
Remaining scrap is blown out together.Therefore, the discharge chip removal ability of mold can be greatly improved, and then avoids causing red needle abrasion very
To the problem of fracture.
Lower mold assemblies 2 may include the punch-pin 21 being sequentially arranged from top to bottom, convex template 22, guide post fixed plate 23, bottom plate 24
And other attachmentes.The assembling mode of lower mold assemblies 2 is well known to those skilled in the art, and is not further described herein.Punch-pin 21
Shape and interior de- plate 16 shape it is corresponding and have through-hole corresponding with red needle hole 161a, 161b, 161c, 161d, 161e.It is convex
Among template 22 have with the shape of the punch-pin 21 it is consistent opening 221, therefore, punch-pin 21 can pass through convex template 22.Together
Sample, guide post fixed plate 23 has through-hole corresponding with red needle hole 161a, 161b, 161c, 161d, 161e, and bottom plate 24 has
There is counterbore corresponding with red needle hole 161a, 161b, 161c, 161d, 161e.
As shown in Figures 4 and 5, the chip space 162 in the 161d of D-shaped red needle hole is located at the both ends of its straight flange.This is a kind of excellent
Embodiment is selected, because D-shaped red needle hole 161d is respectively easy to appear scrap at the both ends of straight flange in punching course.Certainly, in D
Chip space 162 can also be arranged in the arc side of shape red needle hole 161d.
Chip space 162 can be semicircle, rectangle or other shapes.In the shown embodiment, big round red needle hole 161a,
Semicircle chip space 162 and rectangle chip space 162 with interlaced arrangement in middle circle red needle hole 161b；Small circular red needle hole
161c, D-shaped red needle hole 161d and Nei Tuo plate 16 outer peripheral edge in chip space 162 be semicircle；Special-shaped red needle hole 161e's
Chip space 162 has semicircle, also there is rectangle.
The problem of easily snapping off in order to avoid single D-shaped red needle, red needle 17 include two straight flanges that one end links together
D-shaped formed punch 171 relative to each other, as shown in Figure 6.That is, red needle 17 forms gantry structure.The red needle 17 abandons previous single red needle
Structure, have very big reinforcement in structural strength, its service life can be obviously prolonged.In addition, this red needle 17 compares
For single D-shaped red needle, processing is more convenient, and cost is lower.Meanwhile in order to cooperate the red needle 17, two straight flanges that
This opposite D-shaped red needle hole 161d communicates with each other to form a kidney-shaped red needle hole, as shown in Figure 5.In addition, this kidney-shaped red needle hole
Be conducive to chip removal.
In order to remove Burr removal, it is (interior high outer that the inclined-plane with certain angle is processed into the end face 1711 of the D-shaped formed punch 171
It is low, that is, straight flange side is higher), that is, form a blade.Preferably, the inclination angle on the inclined-plane is less than 10 °, it is highly preferred that 3 to
Between 6 °, most preferably 5 °, as shown in Figure 7.
Preferably, red needle 17 is made of SKD11 material.
Now briefly explain the course of work of the utility model.When work, slitting material is sent into against guide pin and positions, when
When upper die component 1 declines with sliding block, concave template 15, convex template 22 first push down billot, prevent a discharge position mobile, then interior de- plate
16 punchings fall the plate above punch-pin 21, go out product shape, and then interior de- plate 16 pushes down product, and red needle formed punch is made to go out product
Inner cavity (mounting hole).At this moment convex template 22 sinks, and product is pushed into concave template 15 by punch-pin, and also tightly hoop takes off plate to scrap inside
On 16.When upper die component goes back up to origin, mandril pressing against thimble push plate 12 and thimble push in de- plate 16 product from cavity plate
151 ejection of the opening of plate 15；Hoop takes off plate 16 and the part scrap on red needle formed punch inside simultaneously, by interior de- plate by the elastic force of spring
It lays down, tracheae is blown at this time, remaining scrap is blown out, then take product away from the chip space 162 on interior de- plate 16, is so far completed
The punch forming process of entire carbon brush holder insulating part.Billot is sent into a step pitch again, carries out punch forming process next time, such as
This is back and forth carried out.
Although specifically showing and describing the utility model in conjunction with preferred embodiment, those skilled in the art is answered
This is understood, in the spirit and scope for not departing from the utility model defined by the appended claims, in form and details
On the utility model can be made a variety of changes, be the protection scope of the utility model.
