Description
Technical field
The utility model belongs to mould applications, is related to a kind of time difference punching die.
Background technique
Traditional mold is when punching, by formed punch on clamping plate, then direct punching is carried out to flitch, direct
When impact, excessive due to shearing, the abrasion of formed punch is very fast, so that the lost of life of formed punch, so to existing mould
Tool is improved.
Utility model content
In view of the deficienciess of the prior art, improving formed punch the purpose of this utility model is to provide a kind of reduction shearing
A kind of time difference punching die in service life.
To achieve the above object, the utility model provides following technical solution: a kind of time difference punching die, including mould
Body, the die body include upper die holder and lower die holder, and the upper die holder is equipped with upper padding plate and upper de- plate, institute towards one end of lower die holder
It states upper padding plate to connect with upper die holder, clamping plate is equipped between the upper padding plate and upper de- plate, the clamping plate is connect with upper padding plate, described
It is equipped on clamping plate and claps thin countersunk head, the described one end of thin countersunk head far from clamping plate of clapping is equipped with pre- formed punch, the cross section of the pre- formed punch
Diameter is less than the cross-sectional diameter for clapping thin countersunk head, and the upper de- plate is equipped with the through-hole with the thin countersunk head cooperation of bat, the lower die holder
It is equipped with lower template towards one end of upper die holder, the lower template is equipped with the counterbore with the thin countersunk head cooperation of bat.
As preferred: being equipped with lower bolster between the lower template and lower die holder.
As preferred: being equipped with baffle plate between the clamping plate and upper de- plate.
As preferred: the lower template is equipped with boss towards one end of upper die holder.
As preferred: the height of the boss is 3mm.
As preferred: the height of the upper padding plate is 15mm, and the height of clamping plate is 20mm, and the height of baffle plate is 15mm,
The height of upper de- plate is 22mm, and the height of lower template is 25mm, and the height of lower bolster is 20mm.
Using above scheme the beneficial effects of the utility model are: when punching, pass through pre- formed punch pair first
Flitch carries out preparatory punching, then claps thin countersunk head and is punched out to flitch, and pre- formed punch can be played and is punched out to flitch,
Then it claps thin countersunk head be punched out, so as to reduce flitch to the shearing for clapping thin countersunk head, has reached reduction shearing, improved punching
The effect in head service life.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of time difference punching die of the utility model.
In figure: 1, upper die holder；2, lower die holder；3, upper padding plate；4, upper de- plate；5, clamping plate；6, pre- formed punch；7, thin countersunk head is clapped；
8, lower template；9, counterbore；10, lower bolster；11, baffle plate；12, boss；13, through-hole.
Specific embodiment
Shown in referring to Fig.1, a kind of time difference punching die that present case is implemented, the die body includes upper die holder 1 and lower die
Seat 2, the upper die holder 1 are equipped with upper padding plate 103 and upper de- plate 4, the upper padding plate 103 and upper die holder 1 towards one end of lower die holder 2
Connection is equipped with clamping plate 5 between the upper padding plate 103 and upper de- plate 4, the clamping plate 5 is connect with upper padding plate 103, on the clamping plate 5
It is equipped with and claps thin countersunk head 7, equipped with pre- formed punch 6, the cross section of the pre- formed punch 6 is straight for the described one end of thin countersunk head 7 far from clamping plate 5 of clapping
Diameter is less than the cross-sectional diameter for clapping thin countersunk head 7, and the upper de- plate 4 is equipped with the through-hole 13 cooperated with the thin countersunk head 7 of bat, the lower die
Seat 2 is equipped with lower template 8 towards one end of upper die holder 1, and the lower template 8 is equipped with the counterbore 9 cooperated with the thin countersunk head 7 of bat, described
It is equipped with lower bolster 10 between lower template 8 and lower die holder 2, baffle plate 11, the lower die are equipped between the clamping plate 5 and upper de- plate 4
Plate 8 is equipped with boss 12 towards one end of upper die holder 1, and the height of the boss 12 is 3mm, and the height of the upper padding plate 103 is
15mm, the height of clamping plate 5 are 20mm, and the height of baffle plate 11 is 15mm, and the height of upper de- plate 4 is 22mm, the height of lower template 8
For 25mm, the height of lower bolster 10 is 20mm.
When punching, first by pre- formed punch 6 to the preparatory punching of flitch progress, thin countersunk head 7 is then clapped to flitch
It is punched out, pre- formed punch 6, which can play, is punched out flitch, then claps thin countersunk head 7 and is being punched out, so as to reduce
Flitch has reached reduction shearing, has improved the effect in formed punch service life to the shearing for clapping thin countersunk head 7.
Embodiment described above is a kind of preferable scheme of the utility model, is not made to the utility model any
Formal limitation, there are also other variations and modifications on the premise of not exceeding the technical scheme recorded in the claims.
