Abstract
The invention discloses a kind of sheet metal component die with edge-folded, comprise the counterdie be arranged on die holder below top patrix and described patrix, the lower surface of described patrix is provided with upwards recessed recess; Described counterdie is provided with recessed depressed portions, and described depressed portions lateral edges bottom is provided with crimping groove; Counterdie material pressing core is provided with between the recess of described patrix and the described depressed portions of described counterdie, described counterdie material pressing core is connected in the resilient support block of die holder by driving the power cylinder of its side-to-side movement, and the crimping groove place that the lower surface outward flange of described counterdie material pressing core corresponds to described counterdie is provided with crimping recess.It is unstable that the present invention can solve existing sheet metal component crimp quality, the inefficient problem of crimping.
Description
Technical field
The present invention relates to machined die technical field, especially a kind of mould for sheet metal component crimping.
Background technology
In machining, the edge often encountering many parts needs the situation of crimping, such as a kind of loader engine hood side door, is formed by the welding of sheet metal parts, is made into the arc edge of side door, needs to carry out crimping to the edge of sheet metal component.The area accounting for whole sheet metal component due to crimping is very little, and the diameter of crimping is also very little, and radian is comparatively large, uses the modes such as mechanical bending to realize.Existing arrangements for automotive doors manufacturing enterprise, generally manually the hair clasp of required radian specification is positioned over inside sheet metal component edge, hand-held iron hammer beats outside sheet metal component edge, shaping to beat, the crimping that radian is evenly round and smooth will be beaten into like this, difficulty is comparatively large, and need higher technology and time, crimping efficiency is lower; And labour intensity is comparatively large, operating personnel easily affect crimping effect because beaing overlong time fatigue, and crimp quality is unstable, and the mode of beaing by hand is also incomplete.
Summary of the invention
Problem to be solved by this invention is to provide a kind of sheet metal component die with edge-folded, unstable to solve existing sheet metal component crimp quality, the inefficient problem of crimping.
In order to solve the problem, technical scheme of the present invention is: this sheet metal component die with edge-folded comprises the counterdie be arranged on die holder below top patrix and described patrix, and the lower surface of described patrix is provided with upwards recessed recess; Described counterdie is provided with recessed depressed portions, and described depressed portions lateral edges bottom is provided with crimping groove; Counterdie material pressing core is provided with between the recess of described patrix and the described depressed portions of described counterdie, described counterdie material pressing core is connected in the resilient support block of die holder by driving the power cylinder of its side-to-side movement, and the crimping groove place that the lower surface outward flange of described counterdie material pressing core corresponds to described counterdie is provided with crimping recess.
Further: the crimping groove of described counterdie is the crimping groove of semi-circular section.
In above-mentioned technical scheme, more specifically technical scheme can be: described patrix is provided with zigzag lug boss and depressed portions, and described counterdie is provided with to interlock with the lug boss of described patrix and depressed portions corresponding lug boss and depressed portions.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, this sheet metal component die with edge-folded adopts patrix shape face and counterdie material pressing core shape face to be compressed by part, crimping can be completed fast, and crimp quality is stablized, easy to use, both labour intensity was reduced, turn improve crimping efficiency, crimping efficiency is reduced to crimping per hour 30 ~ 40 for 2 hours from the original manual needs that complete, and cost is also from completing 100,000 3,000,000 yuan is reduced to 2,150,000 yuan by hand;
2, when part starts crimping, empty without binder state between patrix counterdie outside part, part is easily because stressed meeting is bent outwardly limit shape, the patrix binder surface of this sheet metal component die with edge-folded and counterdie will be designed to as dentation is engaged binder form mutually, make during part crimping, to be subject to the lug boss of upper die and lower die and the support of depressed portions, to ensure part not easily flexural deformation.
