Description
Technical field
The utility model relates to a kind of box-like mould of lobe connected for thin plate impression, belongs to Design of Dies technical field.
Background technology
Along with the competition developing rapidly and be growing more intense of auto industry, lightweight structure and new lightweight material are paid attention to gradually and are developed.The materials such as Al alloys andMg alloys are more and more in the application of the field such as automobile, household electrical appliances, but because these materials chemistries or physical property cause welding performance bad or cannot weld at all, and spot welding is difficult to realize the combination of xenogenesis sheet material, multi-layered board combination and have the connections such as interlayer.Therefore, be badly in need of the plate interconnection technique that exploitation is new, it is that the thin plate that fast development is in recent years got up connects new technology that impression connects.Impression interconnection technique by special impression connecting mold under external force, forces and is connected combination of materials in the flowing of tie point place generation material, form an interlock assembly mutually inlayed by metal plastic deformation.The mould that current domestic production being similar to out can form impression tie point is fixed mould, but the mechanical internal lock utilizing this mould to be formed unreliable, the requirement of impression connection cannot be met.Therefore, design forming mechanical internal lock mould new is reliably needed to meet the requirement of impression connection.
Summary of the invention
The technical problems to be solved in the utility model is: the utility model provides a kind of simple to operate, environmental protection and economy, reduction wearing and tearing, be easy to molding and the box-like mould of lobe is connected for thin plate being easy to be shaped for solve die wear in existing moulding process large, connect rear sheet material not easily molding and the not good problem of formability.
Technical solutions of the utility model are: a kind of box-like mould of lobe connected for thin plate impression, comprises upper die and lower die; Described patrix is punch 1, and described counterdie is the box-like die of lobe, and the box-like die of lobe comprises three identical segmental mandrel 4, cylinder 5, turns 6; Described cylinder 5 is between three identical segmental mandrels 4, punch 1 is positioned at directly over the box-like die of lobe, in three identical segmental mandrels 4, each segmental mandrel 4 side is provided with groove, turn 6 is provided with in the groove of three identical segmental mandrels 4, the front end of punch 1 extends to form the projection that has pattern draft downwards, this projection is positioned at directly over cylinder 5, and described turn 6 is for by three segmental mandrels 4 and cylinder 5 banding, and described pattern draft is designed to
, the corner angle of the described box-like mould of lobe for the connection of thin plate impression are all designed with excessive fillet.
Described three identical segmental mandrels 4 have pattern draft, and pattern draft is designed to
.
Operation principle of the present utility model is: upper plate 2 and lower plate 3 are expressed in the box-like die of lobe by the projection on punch 1, in further extrusion process, there is flowing and the segmental mandrel 4 in the box-like die of lobe expanded to circumferencial direction in upper plate 2 and lower plate 3 material, now turn 6 plays the effect of banding three segmental mandrels 4, the expansion of segmental mandrel 4 makes upper plate 2 and lower plate 3 deformation space increase, there is further flowing in material, thus make upper plate 2 and lower plate 3 by metal plastic deformation formed one mutually inlay in lock construction.
In impression connection procedure, due to the existence of segmental mandrel 4 and turn 6, the space that material is flowed increases further, and the mechanical internal lock therefore making to use this mould to be formed is more solid and reliable.Through many experiments, the pattern draft that segmental mandrel 4 has is designed to
the molding after impression connection can have been met preferably.When wherein its pattern draft being designed to 1 °, after completing impression connection, molding effect is best.
The beneficial effects of the utility model are:
1, the utility model be a kind of do not damage workpiece machining surface can realize thin plate connect new technology, there is feature that is simple to operate, environmental protection and economy;
2, the upper/lower die designed by the utility model is all designed with the knuckle of pattern draft and necessity, reduces the wearing and tearing of mould and the molding being easy to be connected rear sheet material.
3, counterdie designed by the utility model is the box-like mould of lobe, and the expansion of segmental mandrel increases internal modification space, is conducive to the formability that sheet material connects.
4, simple, efficient, the environmental protection of the interconnection technique operation of this mould, easily to be automated, to be a green technology, the important method of attachment of one that advanced automobile of future generation manufactures will be become.
