Description
Technical field
The utility model relates to a kind of mould producing auto parts machinery, the curved reshaping die of especially a kind of automobile-use bonnet.
Background technology
Bonnet is the most eye-catching bodywork component; one of parts that the person that is buying car often will watch; bonnet fully can prevent the adverse effects such as impact, burn into rainwater and electrical interference; adequately protect the normal work of vehicle, to the major requirement of bonnet be heat-insulating sound-insulating, sole mass is light, rigidity is strong.Bonnet is made up of outside plate and inner panel, and outside plate can play air conducting and increase the effect of vehicle aesthetic property, and inner panel can well protect the important automobile part such as engine and periphery pipeline, accessory, plays the effect strengthening rigidity.。To in the production process of bonnet, need to carry out drawing, radium cut, punching, flange, blanking, shaping, deburring shaping, spot welding, polishing, the operation such as baking vanish, complex-shaped due to bonnet, high to the designing requirement of diel, difficulty of processing is large, when carrying out large-scale production, due to punching press often, stroke is long, the service life of traditional dies falls short of, cause mould cost depletions excessive, add production cost.
Summary of the invention
For solving the problem, the utility model provides a kind of automobile-use bonnet curved reshaping die.
The technical scheme in the invention for solving the technical problem is: the curved reshaping die of a kind of automobile-use bonnet, comprise upper bolster and die shoe, described upper bolster is provided with upper cores, described die shoe is provided with lower die, the side of described lower die is provided with workpiece backing-out punch, in the left side of described upper cores and lower die, left wearing plate and left guide plate are installed, on the right side of described upper cores and lower die, right wearing plate and right guide plate are installed; Described upper bolster is provided with buttress brace above upper cores, and the side of described buttress brace offers nitrogen spring preformed hole, and described nitrogen spring preformed hole is provided with nitrogen lid.
Further, described buttress brace is # word lattice.
Further, the sidewall of described buttress brace offers plurality of through holes, can be used for draining the water away.
The beneficial effects of the utility model are: the utility model can be used in the large-scale production operation to automobile engine cover, and when punching press, its wearability is good, long service life, reduces the production cost of enterprise.
