Description
Technical field
The utility model is related to mould applications, and stress springs back mould structure when more particularly to a kind of inhibition arc fold bending.
Background technology
Diel is essential process equipment in punching production, the quality of stamping parts, production efficiency and is produced into
This etc. has direct relation with mold design.There are many kinds of the types of diel, wherein bender be make plate blank or its
His blank is generated along straight line or bending line to be plastically deformed, to obtain the mold of certain angle and shape workpiece.
When using the ending of Bending Mould pressing sheet material, there is residual stress, these residual stress in plank body
It balances each other with the contact force of tool；After the active force of diel is cancelled, i.e.,：After product is unloaded from Bending Mould,
Plank will find new equilbrium position, and local residual stress is released, and the finally formed angle of product is caused to be deposited with desired value
In certain deviation, i.e.,：Generate rebound phenomenon.
In order to reduce the rebound phenomenon that bending deformation generates, existing mode is usually whole section of bending pressurization muscle, makes bending
It is yielding, for being susceptible to following bad phenomenon and deficiency when long section arc fold bending：
1. grow section bending only cannot be guaranteed bending effect by whole section of beading；
2. larger impact can be had to arc by growing the subtle stress rebound of section bending；
3. whole section of bending pressurization muscle subsequently needs additional trimming, comparatively laborious.
Utility model content
The utility model mainly solving the technical problems that provide a kind of inhibitions arc fold bending when stress rebound mould structure,
The requirement for inhibiting folding stress rebound can either be reached, the size and appearance of product are unaffected, while being eliminated follow-up
Trimming.
In order to solve the above technical problems, the technical solution that the utility model uses is：A kind of inhibition arc folding is provided
Stress springs back mould structure when curved, including upper die holder and lower die holder, the bottom end of the upper die holder are provided with punch, the lower die holder
On be provided with insert, whole section of beading is alongst provided in the insert, multiple lists are provided in the whole section of beading
Point type beading, the top of the single-point type beading are higher than the top of the whole section of beading, buoyant pin are provided on the lower die holder,
The buoyant pin is provided with material strip away from the top of the lower die holder.
Preferably, the single-point type beading is uniformly distributed along the length direction of the whole section of beading.
Preferably, the top of the single-point type beading is higher than the 0.2mm~0.5mm on the whole section of beading top.
Preferably, the single-point type beading is rounded corner away from the apex angle of the whole section of beading.
Preferably, the bottom end of the upper die holder is provided with de- material backing plate, is set between the de- material backing plate and the cope plate
It is equipped with upper padding plate, de- material backing plate bottom end is provided with stripper plate.
Preferably, it is provided with lower template on the lower die holder.
The utility model has the beneficial effects that：
1, the requirement for inhibiting the rebound of long arc shape folding stress has both been reached, has in turn ensured that the radian of the whole segment length's arc of product is wanted
It asks, while the size of product and appearance are unaffected.
2, influence of the long section arc fold bending forming stress rebound to radian is reduced, while eliminating subsequent shaping work
Sequence improves production efficiency.
