Description
Technical field
This utility model is related to a kind of small size corrugated plating manufacture field, thin more particularly, to a kind of small size ripple
Plate crimping unit.
Background technology
Corrugated plating because of light weight, with certain bearing capacity, while be also a kind of energy-absorbing original paper of good performance, therefore
Extensively apply in the structural members such as aviation, automobile, ship.
At present, the making of corrugated plating is mainly flanging technology.Using folding brake flanging, the distance of each ripple is required for surveying
Amount, labor intensity is very big, and because measurement error causes ripple size inconsistent, the accuracy of manufacture is poor, it is difficult to ensure that each rib of waveform groove
Side is parallel and separation consistent size.Especially for the thin corrugated plating of small size, (thickness is less than 1mm, the ripple length of side in millimeter
Level), this method mismachining tolerance is excessive.Therefore, flanging technology is difficult to reach pattern requirement.Using traditional dies flanging, can keep away
Exempt from the situation that each seamed edge of waveform groove is not parallel and separation size is inconsistent.But in type corrugated plating is consolidated due to lacking
It is fixed, easily there is the phenomenon of the multiple flanging of each seamed edge of waveform groove.
Suppressed using mould, all corrugated plating one or many be able to will be machined, ripple concordance is good.But in production
Thin corrugated plating occurs some problems in pressing process in practice, wherein common problem has：
(1) the abrasive phenomenon of sheet surface often occurs in pressing process, this is mainly due in stripper plate sheetmolding
When, the gap between mould and plate inclined-plane is too small, occurs in that mould inclined-plane touches dead phenomenon with plate inclined-plane.Produce this to show
The main cause of elephant is that the tool steel for making mould occurs after heat treatment different degrees of deformation, so that originally existing
The gap considered during Design of Dies is destroyed.
(2) plate cracks the phenomenon of even fracture often in pressing process, so as to affect the finished product of plate qualified
Rate.What this was mainly determined by the mechanical performance of sheet material, matched moulds gap and die point (fillet).When yield tensile ratio is less than 0.65,
Plate molding is easier；When yield tensile ratio is more than 0.78, than relatively low, molding is more difficult, and crackle is difficult to for the elongation percentage of plate
Control.Matched moulds gap is excessive, and plate resilience distortion is serious；Gap is too small, the easy pressing crack of plate.Additionally, fillet gets over platelet
The easier pressing crack of piece.
(3) plate fillet position elder generation molding in pressing process, this will affect the slip of sheet material.Under fillet effect,
Material can be scratched, tension-thining, or even the phenomenon broken occurs.

Dynamic direction, makes the upper die and lower die accurately ratcheting, and in the lead column retracting spring is arranged with, for inciting somebody to action after the completion of flanging
The smooth backhaul of the upper mould.
Further, the upper die and lower die size leaves surplus, and the deformation according to the thin plate and flanging effect
Fruit is modified by grinding machine.
Further, the tooth of the wave groove and the equal rounding of the tooth of slide block, radius is 1.2t, and wherein t is the thin plate
Thickness.
Preferably, grinding process is carried out at the tooth rounding, reduces its roughness.
Preferably, the lower mould also includes stock guide, for making the thin plate enter into the lower mould parallel to stock guide
Row flanging.
Preferably, the slide block is provided with observation port, for observing whether the thin plate produces multiple flanging situation.
As other side of the present utility model, there is provided a kind of to roll over using described small size corrugated sheet crimping unit
While the corrugated plating for obtaining.
In general, by the contemplated above technical scheme of this utility model compared with prior art, can obtain down
Row beneficial effect：
(1) in the technical solution of the utility model, in design mould with lower mould when consider the remained measure of repairing mold, for thin plate
Deformation and flanging effect are modified with lower mould to upper mould by grinding machine, be in so avoiding because mould is heat treated
Deform and the abrasive phenomenon of caused sheet surface appearance in journey, and effectively have modified plate rebound phenomena, improve plate
The surface quality of piece.
(2) in the technical solution of the utility model, the tooth of tooth and slide block to the wave groove falls the fillet of 1.2t, drop
The resistance that low inclined-plane and part bending radius flow to material, reduces the tensile damage to material, effectively overcomes thin plate
There is the phenomenon of crackle.
(3) in the technical solution of the utility model, the tooth of shoe edge is used for flanging, and the tooth below slide block is used for conduplication side
Ripple afterwards carries out integer, effectively reduces the bounce-back of thin plate, additionally, device of the present utility model can gradually complete ripple
Flanging, ripple concordance is good.
