Abstract
The utility model discloses a stamping die of waste material is jumped in scour protection hole relates to the mould field, and the device includes punch holder and die insert, is equipped with the drift on the punch holder, and the last through -hole that is equipped with of die insert is equipped with bellied card material part on the inner wall near the one end of punch holder, and the clearance between the inner wall of the outer wall of drift and through -hole is greater than card material part along the bellied height of the radial direction of through -hole. The utility model provides a stamping die of waste material is jumped in scour protection hole is with low costs, processing is convenient.
Description
Technical field
This utility model relates to mould applications, is specifically related to the stamping die of a kind of anti-punching jump-scrap
Tool.
Background technology
During utilizing diel processing hole, when carrying on drift, sometimes because of oil too
Glue or drift edge of a knife slight damage so that waste material is easier to jump out.If the waste material jumped out is not
Cleaning, can remain on the table and affect subsequent product in time so that subsequent product produces pressure
Hindering phenomenon, if the waste material in frequent fettler station, i.e. waste of manpower reduces again production efficiency.
Producing the situation of jump-scrap during in order to prevent punching, traditional way is to add top on drift
Material pin, but this mode has the disadvantage in that on (1) drift after having added jigger pin inconvenient
Repair a die and grind the edge of a knife；(2) when drift is less, jigger pin thereon is also because size is less
And easily snap off；(3) jigger pin and accessory processing inconvenience thereof.Also can additionally, add jigger pin
Increase cost.
Utility model content
For defect present in prior art, the purpose of this utility model is to provide a kind of one-tenth
The diel of this anti-punching jump-scrap low, easy to process.
For reaching object above, this utility model adopts the technical scheme that: a kind of anti-punching is jumped
The diel of waste material, including train wheel bridge and die mold insert, described train wheel bridge is provided with drift,
Described die mold insert is provided with through hole, and described through hole is on the inwall of one end of described train wheel bridge
Be provided with projection the parts that get stuck, and between the inwall of the outer wall of described drift and described through hole between
Gap gets stuck parts along the protruding height of described through hole radial direction described in being more than.
On the basis of technique scheme, described in the parts that get stuck be multiple raised line, and described convex
Bar extends along described through hole axial direction.
On the basis of technique scheme, described through hole includes cylindrical hole and the taper being connected
Hole, described cylindrical hole is located on the inwall of described cylindrical hole near described train wheel bridge, described raised line.
On the basis of technique scheme, described raised line is sawtooth or wedge structure.
On the basis of technique scheme, described raised line is equal along the circumferencial direction of described cylindrical hole
Even distribution.
On the basis of technique scheme, the outer wall of described drift and the inwall of described cylindrical hole
Between gap be 0.1mm, described raised line along the height that described cylindrical hole radial direction is protruding is
0.05mm。
On the basis of technique scheme, the quantity of described raised line is 3.
Compared with prior art, the utility model has the advantage of:
The diel of the anti-punching jump-scrap in this utility model, in the through hole of die mold insert
Setting gets stuck parts, and when carrying on drift, the parts that get stuck can block waste material, prevents outside waste material
Jump.Comparing with traditional mode setting up jigger pin on drift, this utility model will not be to repairing
Mould and the grinding edge of a knife bring impact, and the problem that will not produce jigger pin frangibility it also avoid multiple
A difficult problem for miscellaneous accessory processing difficulties, simultaneously can also be cost-effective.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Shown in Figure 1, this utility model provides the diel of a kind of anti-punching jump-scrap,
Including train wheel bridge 1 and die mold insert 2.
Train wheel bridge 1 is provided with drift 11, corresponding be provided with on die mold insert 2 logical
Hole 21, the through hole 21 inwall near one end of train wheel bridge 1 is provided with the parts 22 that get stuck of projection,
And the gap between the inwall of the outer wall of drift 11 and through hole 21 is more than the parts 22 that get stuck along logical
The height that hole 21 radial direction is protruding, it is ensured that the parts 22 that get stuck do not interfere with drift 11
Work.
The parts 22 that get stuck in this utility model are for multiple raised lines, and raised line is along through hole 21 axially side
To extension.Through hole 21 includes cylindrical hole 211 and the bellmouth 212 being connected, wherein cylinder
Hole 211 is near train wheel bridge 1, and raised line is then arranged on the inwall of cylindrical hole 211, arranges taper
Hole 212 is for more preferable blanking.
Referring also to shown in Fig. 2 and Fig. 3, the parts 22 that get stuck in this utility model include 3
Raised line, it is uniformly distributed along the circumferencial direction of cylindrical hole 211.Wherein the outer wall of drift 11 with
Gap between the inwall of cylindrical hole 211 is 0.1mm, and raised line is along cylindrical hole 211 radial direction
Protruding height is 0.05mm.After raised line is set, when carrying on drift 11, can block useless
Material, thus well prevent waste material from jumping out.Owing to waste material is with certain tapering, in order to more preferably
Block waste material, raised line can make zigzag or wedge shape.Increase on drift with traditional
If the mode of jigger pin is compared, this utility model will not bring impact to repairing a die and grinding the edge of a knife,
The problem that will not produce jigger pin frangibility, it also avoid a difficult problem for complicated accessory processing difficulties,
Simultaneously can also be cost-effective.
This utility model is not only limited to above-mentioned preferred forms, and anyone is at this utility model
Enlightenment under all can draw other various forms of products, no matter but in its shape or structure make
Any change, every have same or like with this utility model as technical scheme, all at it
Within protection domain.
