Description
Technical field
This utility model is related to a kind of micro-hole stamping mold, belongs to the shaping in mechanical engineering and technical field of mold.
Background technology
With the continuous expansion of the fast-developing and its range of application of modern stamping technology, added using punch die in actual production
Work aperture is more and more extensive, the design and manufacture of the quality, production efficiency and production cost and stamping mold of part to be processed
There is direct relation.But in blanking process, stripper produces inclination in motor process because stress is unequal, so that drift
Easily snap off.Drift is too little with die sheet separation, and material rebounds clamp drift, or even " welding ", in the presence of stripping force
Fracture.The one side deformation of stamping gabarit produces uneven cross force, bends drift.
Utility model content
In order to overcome the shortcoming of prior art, the utility model proposes a kind of micro-hole stamping mold, by fixed plate,
Stripper, concave template are specifically designed improves drift correcting, no matter allowing drift at the volley or all being wrapped up well in being punched,
Avoid the phenomenon that avalanche occurs during.
Technical solutions of the utility model are as follows:
Micro-hole stamping mold, including upper bolster and die shoe, the upper bolster lower section is sequentially provided with upper padding plate, fixation
Plate, stripper backing plate and stripper, the die shoe top is sequentially provided with lower bolster and concave template, and the fixed plate is provided with punching
Head, short insert and long insert, the stripper is provided with stripper insert, and the concave template is provided with concave template insert.
Used as preferred, the upper surface of the height of the short insert to stripper, the long insert height is beaten more than mould
The number of drift reinforcement part when dead, the short insert and long insert is 2, is diagonally arranged in around drift.
Used as preferred, the number of the stripper insert is 2, and the stripper insert is diagonally arranged, two strippers
Working portion die cavity is constituted between stripper between insert, the working portion die cavity internal diameter size is more than stripper insert
Outer contour.
Used as preferred, the number of the concave template insert is 4, diagonal row is, in the concave template insert
It is provided with insert cutting edge, the thickness of the insert cutting edge is 1mm, can effectively anti-tripping waste and anti-blocking waste material.
Used as preferred, the drift is adapted into the depth of die with the thickness of insert cutting edge, is 1mm.
This utility model beneficial effect is:Fixed plate fixes drifts using four inserts, two short inserts and two it is long
Insert, the purpose of piecemeal is processed with high-precision grinder to reach, and improves the positioning precision of drift.Four inserts are using two length
Two short modes, two long inserts are that, in order to increase the regular length of drift, drift can be played preferably at work to drift
Protective effect, two short inserts are to provide space to increase stripper insert.The purpose of stripper insert is in order to insert is adopted
Processed with high-precision grinder, for the very short part of punch diameter high-precision guiding is provided, improved the intensity of drift and use the longevity
Life.The purpose of concave template insert is, in order to insert is processed using high-precision grinder, to make the axiality of drift and concave template higher, is dropped
Low drift side force in the course of the work, improves the service life of drift, so as to ensure that what is produced is smoothed out.

Specific embodiment
This utility model is described in further detail below in conjunction with the accompanying drawings.
Embodiment 1, refering to Fig. 1.
Micro-hole stamping mold, including upper bolster 1 and die shoe 2, the lower section of the upper bolster 1 is sequentially provided with upper padding plate 5, consolidates
Fixed board 6, stripper backing plate 7 and stripper 8, the top of the die shoe 2 is sequentially provided with lower bolster 3 and concave template 4.
Wherein, fixed plate 6 plays a part of fixed drift 9, short fixed plate insert 10, long fixed plate insert 11, stripper 7
Play a part of positive stripper insert 12, stripper 8 plays a part of to position stripper insert 12 and guiding drift 9.
With reference to Fig. 3, the upper surface of the height of the short insert 10 to stripper 8, the height of long insert 11 exceedes mould
The number of the drift reinforcement part 14 when killing, the short insert 10 and long insert 11 is 2, is diagonally arranged in drift 9
Around.
Wherein, long insert 11 is that, in order to increase the regular length of aperture drift, short insert 10 is left a blank in advance for stripper insert
Between, making the working portion of aperture drift 9 also has guiding.
With reference to Fig. 4, the number of the stripper insert 12 is 2, and the stripper insert 12 is diagonally arranged, two strippers
Working portion die cavity 16 is constituted between stripper 8 between insert 12, the internal diameter size of the working portion die cavity 16 is more than discharging
The outer contour of plate insert 12.
Wherein, the internal diameter size of the working portion die cavity 16 increases work more than the outer contour of stripper insert 12
Partly molding cavity 16, prevents break flour that drift 9 is stuck.
With reference to Fig. 5, Fig. 6, the number of the concave template insert 13 is 4, is diagonal row, the concave template insert
13 are provided with insert cutting edge 15, and the thickness of the insert cutting edge 15 is 1mm.
Wherein, concave template insert 13 is provided with the insert cutting edge that thickness is 1mm, with effective anti-tripping waste and anti-blocking useless
