The mould structure of angle material folding flange.
Background technique
As shown in Figure 1 and Figure 2, in the prior art scheme, hood part band negative angle flange is real in different processes
It is existing.Since aluminium sheet part is more demanding to falling to consider to be worth doing, to avoid waste knife design that clast is brought to pollute, using sequence deburring is divided, it is pressurized
Machine production line limitation, in the case where rear process only has the basis of three processes at present, it is necessary to realize one sequence of hood along all flange.
Since aluminium sheet young modulus of material only has steel plate 1/3, aluminium sheet part rebounding ratio steel part is bigger, passes through CAE simulation point
Analysis improves part size rebound using the form of material folding flange very big.Due to part negative angle problem (part after wedge flanging
Can not vertically directly take out, as shown in Figure 3), it needs to design new material returned mode convenient for part removal, realizes that punching automation is raw
It produces.
When three face wedge flanging of hood part, if all design activity punch-pin evacuation negative angles of three face inclined wedge positions, activity is convex
Mould movement be easy to cause movement interference, so design two sides movable punch, front side solid punch, part need to transport forward in lower die
Dynamic a distance, avoids the negative angle of front side.But after using elastic device due to material folding flanging lower die, after upper and lower mould disengages, zero
Part flange face is clipped between press plate and punch-pin, and part can not move evacuation negative angle, causes automatic material taking difficult.
