Description
Technical field
The present invention relates to a kind of mould, be specially a kind of cambered surface punching die.
Background technology
Mould, as the one of the high efficiency tool of production, is to use extremely wide Yu important technological equipment in commercial production.Use mould article of manufacture and part, there is production efficiency high, the large batch of production of high speed can be realized, save material, it is achieved chipless is processed；Constant product quality, there is good interchangeability, simple to operate, knot operator do not have the highest technology requirement, the part processing charges utilizing mould to produce in batches is low, and the part processed can be once-forming with product, it is not necessary to reprocesses, the manufactured part that other technological method for processing is difficult to, shape matching is complicated can be produced, easily realize the feature of the automatization produced.
Cambered surface punching die, it it is exactly the process requirements of perforate on cambered surface part, the highest to the processing request precision of punching, because the requirement of product cambered surface, common mould is easily flattened by mould during punching, produce plastic degeneration, affect its intensity and outward appearance, cause overall mechanical property to be destroyed；Simultaneously as product is structure special-shaped, punch process can not be beaten effectively in this position needed, and causes training off, and the quality of product is produced impact, even results in follow-up use to cause equipment and works the mischief, and it is attractive in appearance to have impact on monnolithic case.
Therefore, for solving the problems referred to above, a kind of new technical scheme of special offer.
Summary of the invention
It is an object of the invention to provide a kind of rational in infrastructure, it is ensured that the cambered surface punching die of the stability of cambered surface punching and the quality of product.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of cambered surface punching die, including upper die and lower die, described upper mold is from top to bottom disposed with: upper bolster, retainer plate, train wheel bridge and cope match-plate pattern, described lower mold is disposed with from the bottom to top: bottom plate, die shoe, lower plate and lower bolster, described upper bolster, retainer plate, train wheel bridge and cope match-plate pattern are connected by upper mold screw, and described bottom plate, die shoe, lower plate and lower bolster are connected by lower mold screw；Being provided with fast flushing device on described upper bolster, described retainer plate is provided with outer guiding post and inner guiding post, described train wheel bridge is provided with nitrogen spring by set screw, and described nitrogen spring lower end is provided with drift, and described inner guiding post and drift match with cope match-plate pattern；Being provided with several suckers on described lower bolster, described sucker is connected with the joint being arranged on bottom plate by trachea, and described lower plate is provided with trachea groove, and described trachea is connected with sucker by trachea groove, and described die shoe is provided with outer bush.
Further, described cope match-plate pattern lower surface is concave structure, and described lower bolster upper surface is convex shape.
Further, described fast flushing device includes cylinder, slide block and limited block, described cylinder connection sliding block, and slider bottom is provided with a limited block, and described limited block is connected through retainer plate, train wheel bridge with cope match-plate pattern.
Further, described cope match-plate pattern keeps consistent with the cambered surface of lower bolster with the cambered surface of product.
The invention has the beneficial effects as follows: this mould structure is reasonable, product quality, productivity ratio and die life can be improved, operation equipment and personnel can be reduced simultaneously, reduce production cost, improve production efficiency, and by being accurately positioned, improve the degree of accuracy of product, decrease disqualification rate.
