A quick punching device is mounted on the upper die seat, an outer guide column and an inner guide column are mounted on the supporting plate, a nitrogen spring is mounted on the upper clamping plate through a set screw, a punch is mounted at the lower end of the nitrogen spring, and inner guide column and the punch are matched with the upper die plate. A plurality of suckers are mounted on the lower die plate and connected with connectors on the lower supporting plate through air pipes, and the lower plate is provided with air pipe grooves through which the air pipes are connected with the suckers. The cambered punching die has the advantages that the die is structurally reasonable, production quality and productivity can be improved, and service life of the die can be prolonged; in addition, operation equipment and personnel can be reduced, and accordingly production cost is reduced while production efficiency is improved; moreover, by means of precision positioning, product precision is improved, and rejection rate is decreased.

Description

A kind of cambered surface punching die
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 use in industrial production very extensively and important technological equipment.Adopt mould article of manufacture and part, there is production efficiency high, the large batch of production of high speed can be realized, save material, realize chipless processing; Constant product quality, there is good interchangeability, simple to operate, knot operating personnel do not have very high technical requirement, the part processing charges utilizing mould to produce in batches is low, and the part processed and product can be once-forming, does not need to reprocess, the manufactured part that other technological method for processing is difficult to processing, shape matching complexity can be produced, easily realize the feature of the automation of producing.
Cambered surface punching die, it is exactly the process requirements of perforate on cambered surface part, very high to the processing request precision of punching, because the requirement of product cambered surface, common mould is easily flattened by mould in the process of punching, produce plastic degeneration, affect its intensity and outward appearance, cause overall mechanical property to be damaged; Simultaneously because product structure special-shaped, punch process can not beat the position at these needs effectively, causes training off, and has an impact to the quality of product, even causes causing equipment in follow-up use working the mischief, and it is attractive in appearance to have impact on monnolithic case.
Therefore, for solving the problem, spy provides a kind of new technical scheme.
Summary of the invention
The object of this invention is to provide a kind of rational in infrastructure, ensure 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, comprise upper die and lower die, described patrix is from top to bottom disposed with: upper bolster, retainer plate, train wheel bridge and cope match-plate pattern, described counterdie 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 are connected by patrix screw with cope match-plate pattern, and described bottom plate, die shoe, lower plate are connected by counterdie screw with lower bolster; Described upper bolster is provided with fast flushing device, 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; Described lower bolster is provided with several suckers, described sucker is connected with the joint be arranged on bottom plate by tracheae, and described lower plate is provided with tracheae groove, and described tracheae is connected with sucker by tracheae 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 comprises 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 with cope match-plate pattern through retainer plate, train wheel bridge.
Further, the cambered surface of described cope match-plate pattern and lower bolster and the cambered surface of product are consistent.
The invention has the beneficial effects as follows: this mould structure is reasonable, can improve the quality of products, productivity ratio and die life, operating equipment and personnel can be reduced simultaneously, reduce production cost, improve production efficiency, and by accurately locating, improve the accuracy of product, decreasing disqualification rate.
