Description
Technical field
The present invention relates to one and turn over contour stepped hole composite die for double-deck panel beating cylinder side, belong to metal plate punching neck
Field technique field.
Background technology
Nowadays in automobile industry, the cylinder that disappears after passenger car uses bilayer, and its air inlet turns over contour stepped hole
The prevailing technology that has been increasingly becoming in industry of technique, proposing aperture contour is the track in order to simplify welding bead.Double-deck panel beating
Cylinder side is turned over contour stepped hole and is currently mainly used the following two kinds scheme: one, front at eyelet (rolling) at double-deck panel beating cylinder,
The most respectively sheet material upper punch sub-elliptical irregularly-shaped hole (irregularly-shaped hole of internal layer cylinder is less than the irregularly-shaped hole of outer layer barrel, abnormity
Hole be need by panel beating CAE software calculated), then carry out inside and outside laminate material positioning, butt-joint together, the most right
It carries out the limit at two of eyelet (rolling), down tilt double-layer barrel；Finally with the irregularly-shaped hole location that internal layer cylinder is the most made, put
It is placed in hole flanging mold and carries out hole flanging；Finally obtain a contour stepped hole of approximation (internal layer aperture is higher than in the side of cylinder
Outer layer aperture).The defect of this scheme: it, all being in flat condition when, is carried out by the cylinder of the most inside and outside layer respectively
Rush sub-elliptical irregularly-shaped hole；Then carry out inside and outside cylinder positioning, butt-joint, then rolls together.Abnormity after rolling
Under hole and flat condition spatially for there is certain deformation in irregularly-shaped hole, and this can cause the irregularly-shaped hole under two states to be different
's；Furthermore, inside and outside layer cylinder sheet material is when positioning, it is difficult to ensure that the irregularly-shaped hole of the irregularly-shaped hole of internal layer and outer layer is coaxial
Degree.The superposition of two unfavorable factors, although ultimately resulting in the stepped hole routed up cylinder side to ensure that the aperture of internal layer cylinder is high
Degree is above the aperture height of outer layer barrel, but but it is difficult to ensure that be the hole height of same layer cylinder be contour.
Two, this scheme compares the first scheme, before double-deck panel beating cylinder eyelet be need not sheet material is carried out pre-rush different
Shape hole.But, first carry out inside and outside laminate material positioning, butt-joint is carried out by custom mold together, then by double sheets
Eyelet so that it is become the limit at a cylinder, again two of down tilt double-layer barrel, finally cylinder is positioned over the composite die of customization
In, by the driving of hydraulic press, double-layer barrel is punched out, hole flanging two procedures, finally the side at cylinder also obtains
The stepped hole (internal layer aperture is less than outer layer aperture) that one approximation is contour.The defect of this scheme: although have employed punching, turning over
Hole duplex sequence compound die, but in this operation rushing irregularly-shaped hole, drift is by the irregularly-shaped hole punching together of inside and outside cylinder side
, although this ensure that the axiality of inside and outside cylinder side irregularly-shaped hole, but this makes the irregularly-shaped hole of inside and outside layer cylinder side
Shape be living；In follow-up hole flanging operation, although also can rout up stepped hole (the internal layer cylinder hole that approximation is contour
Open height is less than outer layer barrel aperture height)；And what the high low head of the contour aperture height of this so-called approximation controlled
Also and bad, can not meet the requirement of drawing.Such interior low outer high contour stepped hole that approximates is not that we want,
There is the biggest welding drawback and (just owing to the aperture height of internal layer cylinder is less than outer layer barrel aperture height, cause in this stepped hole
When welding, the aperture of internal layer cylinder there will be weldering loosely, weldering less than defect), so may cause cylinder in the later stage
Abnormal sound, even at the aperture of cylinder occur fracture risk.
