A kind of cambered surface punching die
The present invention relates to a kind of mould, be specially a kind of cambered surface punching die.
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.

Detailed description of the invention
A kind of cambered surface punching die as shown in Figure 1 and 2, comprise upper die and lower die, patrix is from top to bottom disposed with: upper bolster 1, retainer plate 2, train wheel bridge 3 and cope match-plate pattern 4, counterdie is disposed with from the bottom to top: bottom plate 5, die shoe 6, lower plate 7 and lower bolster 8, upper bolster 1, retainer plate 2, train wheel bridge 3 are connected by patrix screw 9 with cope match-plate pattern 4, and bottom plate 5, die shoe 6, lower plate 7 are connected by counterdie screw 10 with lower bolster 8, upper bolster 1 is provided with fast flushing device, and retainer plate 2 is provided with outer guiding post 11 and inner guiding post 12, train wheel bridge 3 is provided with nitrogen spring 13 by set screw, and nitrogen spring 13 lower end is provided with drift 14, and inner guiding post 12 and drift 14 match with cope match-plate pattern 4, lower bolster 8 is provided with several suckers 15, sucker 15 is connected with the joint 18 be arranged on bottom plate 5 by tracheae 17, lower plate 7 is provided with tracheae groove 16, tracheae 17 is connected with sucker 15 by tracheae groove 16, die shoe 6 is provided with outer bush 22, cope match-plate pattern 4 lower surface is concave structure, lower bolster 8 upper surface is convex shape, fast flushing device comprises cylinder 19, slide block 20 and limited block 21, cylinder 19 connection sliding block 20, a limited block 21 is provided with bottom slide block 20, limited block 21 is through retainer plate 2, train wheel bridge 3 is connected with cope match-plate pattern 4, the cambered surface of cope match-plate pattern 4 and lower bolster 8 and the cambered surface of product 23 are consistent.
During operation, sucker 15 adsorbs the product 23 be placed on lower bolster 8, ensures that product 23 position when punching can not produce skew, guarantees accuracy and the accuracy of product punching.As Fig. 2, when the mold is closed, cylinder 19 is with movable slider 20 to slide left, the limited block 21 of slide block 20 lower end is impelled to press down, thus drive nitrogen spring 13 pairs of drifts 14 to act on, then drift 14 pairs of products 23 carry out accurate punching, and punching completes rear slider 20 and moves right, thus nitrogen spring 13 and drift 14 are resetted.In mould close stage, it is locked that outer guiding post 11 enters outer bush 22, guarantees mould stability operationally, and inner guiding post 12 acts on product 23, guarantees stability during product work further.
