Description
Technical field
The utility model belongs to technology of die manufacturing field, is related to a kind of mold, and in particular to a kind of raising minor diameter material
Round punch is punched the mold of hard material intensity.
Background technology
When progressive die is punched soft material, accent diameter is less than 1mm, and round punch will not there are problems that fractureing, but
For punching hardness in the higher hard strip material of HRC52-55 range hardness, normal small size round punch structure, by force
Degree is insufficient, it is easy to punch breakage problem occurs.
In order to improve punch intensity, the intensity increase of fixed position can be solved, but for sword by increasing fixed part size
The size of mouth position can not improve, and punch can be broken from cutting edge position and fixed position.
Utility model content
To solve the deficiencies in the prior art, the purpose of this utility model is to provide a kind of raising minor diameter material round punch punchings
The mold of hard material intensity is cut out, can ensure that small-diameter circular punch does not fracture using the mold.
In order to realize above-mentioned target, the utility model adopts the following technical scheme：
A kind of mold for improving minor diameter material round punch punching hard material intensity, is fixed including round punch, sheath, punch
Plate, upper padding plate, pin, soket head cap screw are sequentially arranged upper padding plate, punch fixing plate, sheath from top to bottom, the round punch
Fixed position is pressed into sheath, and working position exposes sheath, and the pin fixes sheath and punch fixing plate, by upper padding plate, punching
Head fixed plate, sheath are fastened using soket head cap screw.
It is the plane polished with grinding machine at the top of round punch.
Soket head cap screw and pin are distributed in the both sides of round punch.
Stomata, the upper plane air flue connection of stomata and upper padding plate are machined on the round punch, gas nozzle is installed in mould bases outside,
Waste material is made not jump out using compressed air during for being punched.
Stripper is further included, the stripper Position Design has recessing groove.
The utility model is beneficial in that：Die life can be improved using the mold of the utility model, is subtracted
The problem of few mold caused by when punch fractures can not use substantially increases the utilization rate of mold.

Specific embodiment
Make specific introduce to the utility model below in conjunction with the drawings and specific embodiments.
With reference to Fig. 1, the mold provided by the utility model for improving minor diameter material round punch punching hard material intensity, mainly
Part includes：Round punch 6, sheath 5, punch fixing plate 3, pin 4, upper padding plate 2, soket head cap screw 1.
It is sequentially arranged upper padding plate 2, punch fixing plate 3, sheath 5 from top to bottom, in order to shorten round punch entire length, simultaneously
Shorten land length, sheath 5 is designed on punch fixing plate 3, this sheath 5 is in the following, not being pressed into punch in punch fixing plate 3
3 the inside of fixed plate.The fixed position press-in sheath 5 of the round punch 6, working position expose sheath 5, and the pin 4 is fixed
Sheath and punch fixing plate 3 fasten upper padding plate 2, punch fixing plate 3, sheath 4 using soket head cap screw 1.
During installation, after round punch 6 is pressed into sheath 5, the top of round punch 6 is polished with grinding machine.Again with pin 4 sheath with
Punch fixing plate 3 positions, and finally fastens upper padding plate 2, punch fixing plate 3, the soket head cap screw 1 of sheath 5.It is interior in this mold
Hex screw 1 and pin 4 are distributed in the both sides of round punch, and sheath 5 is positioned using pin hole, then is fastened with soket head cap screw 1, can
To reach the position dimension state that punch is fit directly into punch fixing plate structure.
As shown in Fig. 2, round punch 6 includes fixed position 7 and working position 10, fixed position 7 is pressed into sheath 5, and length is
14mm, including top 8 and fixing end 9, the surface at top 8 is provided with extension to polish state, length 3mm, 9 lower section of fixing end
End, length 3mm, extended end lower section are tapering point, and length 3mm, 10 length of working position is 13mm, and the round punch 6 is whole
Body length is 33mm.
As shown in figure 3, mold solid punch height increases, it is because to increase the whole of punch fixing plate 3 and stripper 12
The thickness of fixed plate 3 and stripper 12 is designed to 22mm by body intensity and dynamic kinetic stability, so need to intensity is low
Punch is individually designed, to increase intensity.
Stripper 12 is stepped down with the design of 5 cooperation position of sheath, the unilateral minimum reservation 0.5mm of both sides, when stripper 12 is pressed
Most in short-term, the safe space between stripper 12 and punch fixing plate 3 is 4mm for contracting.Stripper 12 mainly ensures contracting after stepping down
Round punch intensity after short, while sheath 5 has enough bit spaces that allows, and the big blanking die height 55mm of remaining position,
It is also ensured that cutting edge is concordant.
Shorten round punch entire length, while land length shortens, there are enough dischargings after meeting progressive die assembling
Space is needed in stripper Position Design recessing groove.Recessing groove includes the upper end of 2mm and the lower end of 5mm.
It after the completion of punch assembling, needs to wear stomata φ 0.4--0.8 ranges among round punch 6, stomata and upper padding plate 2
The connection of upper plane air flue, installation gas nozzle on the outside of mould bases.
Process using the Dies ' Blanking of the utility model is as follows：
(1) mold on punching machine being installed, lathe is first reached into bottom dead centre, adjustment stripper is contacted with die plate insert,
It when stripper has slight resilience, needs to be put into strip, at this moment opens lathe again, micro-adjustment is punched depth, makes the cavity of product
Hole is all punched through；
(2) after the punching depth adjustment of lathe is qualified, lathe is locked；
(3) compressed air valve is opened when punching, bypasses air through the stomata of round punch, ensured that waste material is not upper and jump, subtract
Few product weighs wounded.
It verifies by contrast, using the mould punching of the utility model, die life can be significantly improved, because punch is rolled over
Disconnected the problem of causing mold that can not use, is improved, and substantially increases mold utilization rate.
It should be noted that above-mentioned implementation does not limit the utility model in any form, it is all to use equivalent replacement or equivalent
The technical solution that the mode of transformation is obtained, all falls in the scope of protection of the utility model.
