Abstract
It collapses angle entire bright punching fine blanking die the utility model is related to a kind of nothing, including upper die and lower die, upper mold includes cope plate, upper padding plate, middle support plate, gear ring plate and punch-pin, lower die includes lower template, lower bolster and cavity plate, punch-pin includes for the pre-cut punch of pre-cut part sharp corner shape and for shearing the blanking die that External Shape goes out part, the anti-crowded punch for reverse extrusion material by cavity plate guide-localization is fixed on lower bolster, pre-cut punch, anti-crowded punch and blanking die correspond to three processes respectively.The fine blanking die once completes the nothing with shape-angle part and collapses angle entire bright punching, and production efficiency is high, avoids surface and weighs wounded.
Description
Technical field
The utility model belongs to stamping die field, and in particular to a kind of nothing is collapsed angle entire bright punching fine blanking die.
Background technology
Stamping die is that the equipment that pressure processing uses is carried out to material, and operation principle is generally by mold in punching press
Under the action of the folding face of upper die and lower die is driven to be cut the raw material between it, punching, the setting such as stretchings, formed and rushed
Casting die.Fine blanking die is the novel mold of current existing product manufacturing field, the punch-pin die set usually with up and down
Form, punch-pin is fixed by upper padding plate, gear ring plate is oriented to, and upper padding plate and cope plate fix, and gear ring plate and middle support plate are fixed, cavity plate and
Lower template connects, and lower die moves upwards completion production during work.Continuous fine blanking die refers to forcing press in a punching stroke
In, using band-like punching press raw material, complete the cold punching of multi-step forming processes simultaneously with several different stations on a secondary mold
Punch die is pressed, mold is completed once per punching press, and material strip fixed-distance moving is primary, until product is completed.
Without the angle entire bright punching fine blanking die that collapses by precutting, reverse extrusion, blanking, three processes guarantee sharp corner is without angle of collapsing
Punching face entire bright, normal conditions have the part of wedge angle and requirement without the angle entire bright that collapses, using fine blanking made allowance, rear process
Bright finish, process is more, increases manufacture and management cost, the small waste material of finishing are easily pressed in piece surface and cause parts list face pressure
Wound.
Utility model content
The purpose of this utility model is to provide a kind of nothing and collapses angle entire bright punching fine blanking die, which once completes to carry
The nothing of shape-angle part is collapsed angle entire bright punching, and production efficiency is high, avoids surface and weighs wounded.
Technical solution is used by the utility model solves：
A kind of nothing is collapsed angle entire bright punching fine blanking die, and including upper die and lower die, upper mold includes cope plate, upper padding plate, middle branch
Plate, gear ring plate and punch-pin, upper padding plate are fixed on cope plate bottom, and punch-pin is located at upper padding plate bottom, and middle support plate passes through with cope plate
Contour sleeve connection, gear ring plate are fixed on middle the bottom of the support plate, and upper padding plate passes through middle support plate, and punch-pin passes through gear ring plate, and lower die includes
Lower template, lower bolster and cavity plate, lower bolster are fixed at the top of lower template, and cavity plate is connected with lower template by transmission rod and contour sleeve
It connects, there are gap, gear ring plate and cavity plate by guide post guide-localization, punch-pin is included for pre- for die opening state lower cavity die and lower template
It cuts the pre-cut punch of part sharp corner shape and for shearing the blanking die that External Shape goes out part, is fixed on lower bolster
Pass through the anti-crowded punch for reverse extrusion material of cavity plate guide-localization, pre-cut punch, anti-crowded punch and blanking die difference
Corresponding three processes.
Further, pre-cut punch opposing product appearance profile reserves the surplus of material thickness 10%, anti-crowded punch nip width
To expect that thick 5%, depth are thick 80% of material.
The beneficial effects of the utility model are：
The fine blanking die ensures that three precutting, reverse extrusion and blanking processes in a punching press are completed with wedge angle zero
The nothing of part is collapsed angle entire bright punching, reduces subsequent processing operations, production efficiency is high, at low cost；The material of reverse extrusion reserves
On billot, avoid the small waste material of deburring and fall on mold, in case part caused by forming small iron filings weighs wounded, surface quality of workpieces
It is good.
Description of the drawings
Fig. 1 is the Layout that wedge angle class part uses the utility model.
Fig. 2 is the structure chart of the utility model embodiment.
In figure：1- cope plates；2- upper padding plates；Support plate in 3-；4- gear ring plates；5- cavity plates；6- lower templates；7- pre-cut punches；
8- instead squeezes punch；9- blanking dies；10- lower bolsters.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figure 1, it for small wedge angle and requires without Layout of the angle entire bright class part using the utility model that collapse, at this
In example, expect that final molding part needs to complete in three processes of a mold from item.
As shown in Fig. 2, a kind of nothing is collapsed, angle entire bright is punched fine blanking die, including upper die and lower die, upper mold include cope plate 1,
Upper padding plate 2, middle support plate 3, gear ring plate 4 and punch-pin, upper padding plate 2 are fixed on 1 bottom of cope plate, and punch-pin is located at 2 bottom of upper padding plate, in
Support plate 3 is with cope plate 1 by contour sleeve connection, and gear ring plate 4 is fixed on middle 3 bottom of support plate, and upper padding plate 2 passes through middle support plate 3, convex
Mould passes through gear ring plate 4, and lower die includes lower template 6, lower bolster 10 and cavity plate 5, and lower bolster 10 is fixed on 6 top of lower template, cavity plate 5
6 are deposited in gap (gap and part by transmission rod and contour sleeve connection, die opening state lower cavity die 5 and lower template with lower template 6
Material is thick related), by guide post guide-localization, punch-pin includes pre-cut punch 7 and blanking die 9, lower bolster for gear ring plate 4 and cavity plate 5
The anti-crowded punch 8 by 5 guide-localization of cavity plate is fixed on 10, pre-cut punch 7, anti-crowded punch 8 and blanking die 9 are corresponding in turn to
Three processes, pre-cut punch 7 are used for pre-cut part sharp corner shape, and anti-crowded punch 8 is for reverse extrusion material, blanking die 9
Part is gone out for shearing External Shape.
In the present embodiment, 7 opposing product appearance profile of pre-cut punch reserves the surplus of material thickness 10%, and anti-crowded punch 8 squeezes
Pressure width is the 5% of material thickness, depth is thick 80% of material.
Cavity plate 5 moves sticked with lower template 6 under force during punching, and reverse extrusion punch 8, which exposes cavity plate face, to be completed
Reverse extrusion is punched, and lower die continues uplink, gear ring plate 4, middle support plate 3 is driven to move upwardly together, pre-cut punch 7 and blanking die
9, which expose gear ring plate 4, completes pre-cut and blanking.The fine blanking die ensures precutting, reverse extrusion and blanking three in a punching press
A process completes the nothing with shape-angle part and collapses angle entire bright punching, reduces subsequent processing operations, production efficiency is high, cost
It is low；The material of reverse extrusion is reserved on billot, is avoided the small waste material of deburring and is fallen on mold, in order to avoid formed zero caused by small iron filings
Part weighs wounded, and surface quality of workpieces is good.
It should be understood that for those of ordinary skills, can be improved or converted according to the above description,
And all these modifications and variations should all belong to the protection domain of the appended claims for the utility model.
