Abstract
The utility model discloses a kind of cavity plate hydro-drawing devices, it includes: cavity plate, punch-pin and blank holder, and the blank holder is located at the middle of cavity plate and punch-pin, the arrangement increases the forming accuracys rate of part, make the part uniform wall thickness pulled out, thinning rate is reduced, and reduces harmful frictional force.
Description
Technical field
The utility model relates to mould applications, specifically a kind of cavity plate hydro-drawing device.
Background technique
Hydro-drawing manufacturing process is the very strong forming technique of practicability, and application prospect is very wide.In recent years, generation
The processing industry on boundary is towards flexibility, material diversification, product precise treatment, technological design are intelligent, Automation of Manufacturing Process side
To development, production also requires small mount, multi items, the period shortened of successive generations of products increasingly.Hydro-drawing at
The good product quality of shape technique production, precision are high, mold is ring-like fast, are suitable for the life of multi-varieties and small-batch and Complex Different Shape part
The characteristics of producing, also complying with modern production, the development of hydro-drawing new method, new construction is the basic of hydro-drawing method, a side
Face will be combined existing various raising drawing ratio methods, pass through the comprehensive a little raising for embodying various hydro-drawing methods
On the other hand drawing quality will open up new hydraulic action ways and means and further increase drawing ratio.
In drawing process, cupping press by the piece-holder of drawing between upper mould piece and lower module.By upper
Relative motion between module and lower module, the workpiece to drawing are stretched in lower die, and are pressed between two modules
Shape, but in the prior art, the part wall unevenness after drawing is even, and substandard products are more, and working efficiency is low.
Utility model content
Purpose of utility model: purpose of the utility model is to solve the deficiencies in the prior art, provide a kind of cavity plate liquid
Setup for drawing parts is pressed, the forming accuracy rate of part is improved, makes the part uniform wall thickness pulled out, thinning rate is reduced, and is reduced nocuousness and is rubbed
Wipe power.
Technical solution: in order to achieve the goal above, a kind of cavity plate hydro-drawing device described in the utility model, it is wrapped
Include: cavity plate, punch-pin and blank holder, the blank holder are located at the middle of cavity plate and punch-pin；
The cavity plate includes: the polyurethane for holding frame and being placed in appearance frame；
The punch-pin includes: oil cylinder, the piston being equipped in oil cylinder, and the other end of piston is equipped with convex module, is set on piston
Some mandrils.
As the further preferred of the utility model, hydraulic oil is equipped in the oil cylinder.
As the further preferred of the utility model, polyurethane is stratiform polyurethane.
As the further preferred of the utility model, the oil cylinder is connected with overflow valve.
As the further preferred of the utility model, plate is arranged in the appearance frame.
As the further preferred of the utility model, the mandril that the piston is equipped with passes through oil cylinder, offsets with frame is held.
The utility model has the advantages that a kind of cavity plate hydro-drawing device described in the utility model has following compared with prior art
Advantage:
1, in drawing process, plate is tightly coated on punch-pin by soft cavity plate with very big pressure, improve part at
Shape accuracy increases the frictional force of feature side-wall and convex mould surface, alleviates the tensile stress in blank sidewall；
2, critical section constantly shifts, and improves force transmission region tensile strength, and due to increasing between punch-pin and part
Favorable friction power, make the part uniform wall thickness pulled out, thinning rate greatly reduces；
3, the opposite sliding that plate and soft cavity plate side can be reduced, so that harmful frictional force be made to have considerable degree of drop
It is low；
4, the die profile radius in the utility model immobilizes unlike rigid matrix, but in drawing process
From large to small, bending of material when passing through die profile radius is reduced to become smaller resistance；
5, in drawing process, soft cavity plate plays the role of revocation and cavity plate edge is pushed inwardly to flow, to be conducive to drawing change
Shape.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
With reference to the accompanying drawing, the utility model is furtherd elucidate.
As shown in the picture, a kind of cavity plate hydro-drawing device described in the utility model, it includes: piston 1, overflow valve 2,
Oil cylinder 3, convex module 4, blank holder 5 hold frame 6, stratiform polyurethane 7, plate 8, mandril 9, cavity plate 10 and punch-pin 11.
Blank holder 5 is located at the middle of cavity plate 10 and punch-pin 11；Cavity plate 10 includes: the layer for holding frame (6) and being placed in appearance frame 6
Shape polyurethane 7；Punch-pin 11 includes: oil cylinder 3, the piston 1 being equipped in oil cylinder 3, and the other end of piston 1 is equipped with convex module 4, piston 1
The mandril 9 being equipped with passes through oil cylinder 3 and offsets with frame 6 is held, and oil cylinder 3 is connected with overflow valve 2, holds in frame 6 and is arranged with plate 8.
Embodiment
Plate 8 is stuck in blank holder 5, is gradually filled with hydraulic oil in oil cylinder 3, makes piston 1 that convex module 4 be pushed to move upwards
When, plate 8 is headed by convex module 4 holds frame 6, and after the contact of 8 stratiform polyurethane 7 of plate, the oil pressure in oil cylinder 3 is increased, in oil cylinder 3
Hydraulic oil by 8 hard-pressed bale of plate on convex module 4, at this point, plate 8 gradually deforms, when the oil pressure in oil cylinder 3 reaches limit value,
Hydraulic oil is discharged from overflow valve 2, to keep the oil pressure steady state value in oil cylinder 3, at this point, when convex module 4 reaches restriction stroke, plate
8 by drawing to finished product, and the hydraulic oil in oil cylinder 3 is exported, so that hydraulic oil gradually tails off, piston 1 does backhaul fortune gradually downward
Dynamic, to drive 4 backhaul of convex module, mandril 9 assists demoulding, after finished product is taken out, can install plate 8 again, be ready for
Drawing next time.
Above embodiment is only to illustrate the technical ideas and features of the present invention, and the purpose is to allow be familiar with technology neck
The technical staff in domain can understand the content of the utility model and implement accordingly, and the guarantor of the utility model can not be limited with this
Protect range.All equivalent changes or modifications substantially made according to the spirit of the present invention, should all contain device in the utility model
Protection scope within.
