Abstract
The invention discloses a panel veneer liquid filling and drawing forming method based on a parallel mechanism, and belongs to the technical field of panel veneer hydraulic machining. According to the method, hydraulic forming is conducted on the basis of the parallel mechanism, a male die is connected to the parallel mechanism, and the space posture of the male die is controlled through the parallel mechanism; in the male die descending and withdrawing process, the space posture can be changed, and therefore forming of complex components can be achieved; the panel veneer transformation path is changed and optimized by optimizing the descending space path and posture of the male die, and the panel veneer liquid filling and drawing performance is further improved. By means of the method, liquid filling and drawing of some shell components difficultly subjected to withdrawing become possible; in addition, in the method, male die feeding is achieved through constant transformation of the male die space postures, accordingly, the panel veneer strain path is changed, and the panel veneer forming performance can be further improved by optimizing the strain path.
Description
Technical field：
The invention belongs to Sheet metal forming processing technical field, and in particular to a kind of plate liquid filling deep-drawing based on parallel institution
Manufacturing process.The present invention by it is progressive change punch spatiality realize punch motion, it is possible to achieve complex space shape into
Shape, and the forming property of plate can be further improved by optimizing strain paths.
Background technology：
Plate liquid filling deep-drawing belongs to sheel metal flexible processing method, and it replaces die with the liquid of high pressure, using soft
Die realizes the flexible forming of plate.Traditional hydro-mechanical drawing its drawing direction is all straight line as common drawing direction, that is, rush
The direction of motion of mould is linear motion.Punch die can only move along a straight line, and limit the shaping scope of sheet-metal press working part, such as right
In some as the typical part of one class of elbow, its punch die if cannot just be entered die, and common punching press by linear motion
Such part cannot be shaped with hydro-mechanical drawing is passed.
The content of the invention：
Present invention aim at providing a kind of plate liquid filling deep-drawing method based on parallel institution, the present invention is utilized and is coupled
Structure realizes that punch is fed along pahtfinder hard, realizes that common punching press is difficult to the shaping of coin complex part；Meanwhile, using parallel institution
The progressive asymmetric descending of punch is realized, the inhomogeneous deformation of plate is realized, the Deep-drawing property of plate is improved.
A kind of plate liquid filling deep-drawing method based on parallel institution provided by the present invention, the method are comprised the following steps that：
(1) punch is connected with parallel institution, the stroke of the punch and spatial attitude are by the parallel institution come real
Now and control.
(2) hydraulic oil will be full of in liquid pool, the punch is controlled by the parallel institution and enters recessed along certain curve
In mould, the liquid in liquid pool is by its pressure of HYDRAULIC CONTROL SYSTEM, and makes plate to be formed progressively be adjacent to the punch, so that
The plate to be formed is formed.
(3), after the plate to be formed shaping is finished, the withdrawing pattern path rail of the punch is controlled by the parallel institution
Mark and spatial attitude realize withdrawing pattern, it is to avoid the interference of punch and drip molding during simple withdrawing pattern.
The descending attitude of institutional adjustment in parallel of the invention and optimization punch space, realizes that punch is descending, the common punching of shaping
Pressure is difficult to the part of withdrawing pattern.According to the characteristics of part, optimize punch running orbit and attitude, by changing for plate strain paths
Become, further improve the forming property of plate.
Using parallel-connection structure, the present invention realizes that punch is fed along pahtfinder hard, realize that common punching press is difficult to coin complex part
Shaping；Meanwhile, the progressive asymmetric descending of punch is realized using parallel institution, realize the inhomogeneous deformation of plate, improve plate
The Deep-drawing property of material.
