Abstract
The invention discloses a sheet metal part edge rolling die. The sheet metal part edge rolling die comprises an upper die and a lower die which is located below the upper die and installed on a die seat, wherein the lower end surface of the upper die is provided with a recess portion which is upwards recessed, the lower die is provided with a downwards concaved portion which is downwards concaved, an edge rolling groove is arranged at the bottom end of the side edge of the downwards concaved portion, a lower die pressing core is arranged between the recess portion of the upper die and the downwards concaved portion of the lower die, the lower die pressing core is connected with an elastic support block of the die seat through a power cylinder which drives the lower die pressing core to perform side-to-side movement, and the position at the outer edge of the lower end surface of the lower die pressing core is provided with an edge rolling concave portion and corresponds to an edge rolling groove of the lower die. According to the sheet metal part edge rolling die, the problem that existing sheet metal parts are unstable in edge rolling quality and low in edge rolling efficiency can be solved.
Description
Technical field
The present invention relates to machining technical field of mold, especially a kind of mould for sheet metal component crimping.
Background technology
In machining, the edge that often can encounter many parts needs the situation of crimping, and for example a kind of loader engine hood side door, is to be formed by the welding of sheet metal parts, be made into the arc edge of side door, need to carry out crimping to the edge of sheet metal component.The area that accounts for whole sheet metal component due to crimping is very little, and the diameter of crimping is also very little, and radian is larger, 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 to be positioned over to inner side, sheet metal component edge, hand-held iron hammer beats outside, sheet metal component edge, to beat moulding, to beat into so evenly round and smooth crimping of radian, difficulty is larger, needs higher technology and time, and crimping efficiency is lower; And labour intensity is larger, easily because beaing, overlong time is tired affects crimping effect to operating personnel, and crimp quality is unstable, and the mode of beaing is by hand 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 address the above problem, technical scheme of the present invention is: this sheet metal component die with edge-folded comprises the counterdie on die holder that is arranged on of top patrix and described patrix below, 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; Between the described depressed portions of the recess of described patrix and described counterdie, be provided with counterdie material pressing core, described counterdie material pressing core is by driving the power cylinder of its side-to-side movement to be connected in the resilient support block of die holder, and the lower surface outward flange of described counterdie material pressing core is provided with crimping recess corresponding to the crimping groove of described counterdie.
Further: the crimping groove that the crimping groove of described counterdie is 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 lug boss and depressed portions staggered corresponding lug boss and the depressed portions with described patrix.
Owing to having adopted 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 that part is compressed, can complete fast crimping, and crimp quality is stable, easy to use, both reduced labour intensity, improved again crimping efficiency, crimping efficiency is reduced to 30～40 of crimpings per hour 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, in the time that part starts crimping, outside part, between patrix counterdie, be empty without binder state, part is easily because of the outwardly-bent limit of stressed meeting shape, the patrix binder surface of this sheet metal component die with edge-folded and counterdie will be designed to interlock binder form as mutual in dentation, while making part crimping, be subject to the lug boss of upper die and lower die and the support of depressed portions, to ensure that part is difficult for flexural deformation.
