Description
Technical field
The utility model belongs to cold punching die scope, more particularly to a kind of explosion-wave-preventing valve deck sizing die.
Background technology
Deflagration wave valve deck stretching depth is big, it is necessary to substep shapes, and after first step stretching, cracks sometimes and fold, it is necessary to
Carry out further shaping.Secondly, to the further flanging forming of stretched parts, the flange angle of design and dig thickness and close very much
Key, angle is big, is unfavorable for shaping in next step, angle is small, produces fold.Workpiece after stretching, carries out flange, shaping, according to setting
The angle of meter carries out flange, easily cracks and fold.
Utility model content
The purpose of this utility model is cracked sometimes and fold for the workpiece after stretching, and carries out flange, whole
Shape, carries out flange according to the angle of design, easily cracks and propose a kind of explosion-wave-preventing valve deck sizing die with the deficiency of fold, its
It is characterized in that, the explosion-wave-preventing valve deck sizing die is made of upper die and lower die；Wherein, cope plate 1, guide post guide sleeve 2. and cavity plate 3
Form upper mold；Punch-pin 4, lower template 5 and elastic discharging device 6 form lower die；Four angles of cope plate 1 and lower template 5 respectively by
Four guide post guide sleeves 2 connect；Elastic discharging device 6 is connected with punch-pin 4 after passing through lower template 5 by 2-4 roots bolt 9；The elastic material returned
The pilot hole 7 that a guide rod 8 passes through 5 center of lower template is fixed at 6 center of device, with ensure punch-pin 4 it is steady, vertically upward or to
Lower movement.
The convex arc edge in upper surface of the punch-pin opens annulus flange groove 10.
The punch-pin and cavity plate use the Cr12 alloy tool steels of quenched processing, perform standard GB/T1299-1985, by force
Spending height being capable of Reusability.
The punch-pin, the circular arc of cavity plate and explosion-wave-preventing valve deck, dimensional fits.
The bolster uses 45 steel, after conditioned processing, has impact flexibility, plasticity and wearability.
The beneficial effects of the utility model are the Cr12 alloy tool steels that punch-pin and cavity plate use quenched processing, perform mark
Quasi- GB/T1299-1985, intensity is high, has preferable quenching degree and good wearability, suitable to bear less impact flexibility, protects
Demonstrate,prove precision；Can be with Reusability；Bolster uses 45 steel, after conditioned processing, obtains higher impact flexibility, plasticity and resistance to
Mill property, suitable for transmitting stamping press, lower die for being compressed before workpiece shaping, and uses guide post guide sleeve using elastic jacking mechanism
Carry out the accurate upper and lower mould that is oriented to mould to exert a force at the same time, stretcher strain is uniform, prevents deflection during mould force, prevents workpiece
Deform uneven.High in machining efficiency, precision is high.
Brief description of the drawings

Embodiment
The utility model proposes a kind of explosion-wave-preventing valve deck sizing die, which is made of upper die and lower die.
It is explained below in conjunction with the accompanying drawings.
Fig. 1, Fig. 2, Fig. 3 show explosion-wave-preventing valve deck sizing die structure diagram.
In figure, cope plate 1, guide post guide sleeve 2. and cavity plate 3 form upper mold；Punch-pin 4, lower template 5 and elastic 6 groups of discharging device
Into lower die；The convex arc edge in upper surface of punch-pin opens annulus flange groove 10, and the circle of punch-pin, cavity plate and explosion-wave-preventing valve deck 11
Arc, dimensional fits（As shown in Figure 3）.Four angles of cope plate 1 and lower template 5 are connected by four guide post guide sleeves 2 respectively；Elasticity is moved back
Material device 6 is connected with punch-pin 4 after passing through lower template 5 by 2-4 roots bolt 9；A guide rod 8 is fixed at elastic 6 center of discharging device
Through the pilot hole 7 at 5 center of lower template, to ensure that punch-pin 4 is steady, vertically upward or moves down.The punch-pin of the utility model
The Cr12 alloy tool steels of quenched processing are used with cavity plate, perform standard GB/T1299-1985, intensity height can make repeatedly
With.Bolster uses 45 steel, after conditioned processing, has preferable quenching degree and good wearability, is adapted to bear smaller
Impact flexibility, plasticity and wearability.Mould requirement on machining accuracy is high, Reusability,
During work, explosion-wave-preventing valve deck sizing die, which is assembled on four-column hydraulic press, to be used, and after assembling, is put into explosion-wave-preventing valve deck
11（Workpiece）, centering, cylinder presses at the same time up and down for control, stretches, and oil cylinder resets, and upper and lower mould is separated, and automatic rebounding moves back lower die at the same time
Material, removes workpiece and completes a complete process.Lower die for being compressed before workpiece shaping, and is used and led using elastic jacking mechanism
Column guide sleeve carries out mould the accurate upper and lower mould that is oriented to and exerts a force at the same time, and elastic 6 center of discharging device is fixed a guide rod 8 and worn
The pilot hole 7 at 5 center of lower template is crossed, to ensure that punch-pin 4 is steady, vertically upward or moves down.During preventing that mould from exerting a force
Deflection, prevents that workpiece deformation is uneven.
