Abstract
The utility model relates to an automatic-ejection type punching die for a closed-contour sheet metal part. According to the technical scheme of the utility model, an elastic die holder of an integral structure is composed of an upper template, a lower template and a connecting plate. An upper die is arranged on the upper template, and a lower die is arranged on the lower template. The middle part of the lower template is provided with a groove. A positioning pin is arranged on the lower die. The contour of the upper die is the same with the contour of the groove. The punching die is simple in operation and good in versatility. Due to the adoption of the punching die, the punching and machining accuracy of any closed-contour sheet metal part can be improved and the labor intensity of workers is reduced. The punching die can be applied to the punching process of sheet metal parts in the automotive and aerospace fields and has the advantages of simple structure, convenient manufacture, low cost and short period. Therefore, the punching die is particularly suitable for the small batch production.
Description
Technical field
The utility model relates to a kind of blanking die, particularly a kind of closed outline sheet metal component eject blanking die.
Background technology
Aviation field can be used a lot of different closed outline sheet metal components, existing process be by diel be placed on punching press lathe, carry out die-cut, the problem existing is stamping die complex structure, and every kind of sheet metal component can only be prepared a kind of stamping die of fixed structure, when this kind of sheet metal component do not produced, stamping die, just in idle state, wastes raw material.After punching press simultaneously, sheet metal component takes off difficulty from metal blank, need to beat just and can take off, and affects the presentation quality of product.
Summary of the invention
In order to overcome the above problems, it is a kind of simple in structure that the utility model provides, and reduces production costs, and feeding is closed outline sheet metal component eject blanking die easily.
The technical solution adopted in the utility model is: closed outline sheet metal component eject blanking die, cope match-plate pattern, lower bolster and connecting plate are integrally formed the elasticity mould bases of structure, patrix is installed on cope match-plate pattern, middle part is installed on lower bolster and establishes reeded counterdie, alignment pin is installed on counterdie.
Above-mentioned closed outline sheet metal component eject blanking die, the profile of patrix is identical with the profile of groove.
Above-mentioned closed outline sheet metal component eject blanking die, connecting plate is arcuate structure.
The beneficial effects of the utility model are: the utility model can improve the accuracy of any enclosed appearance profile sheet metal component punch process, easy and simple to handle, and labor strength reduces, highly versatile.During production, only the upper die and lower die of needed appearance profile need be installed on mould bases, the frock manufacturing cycle is short, low cost of manufacture, and working (machining) efficiency is high.The utility model can be applicable to automobile, the clicking technique of aviation field sheet metal part, and not only simple in structure, easily manufactured, cost is low, and the cycle is short, particularly applicable to new machine development and small lot batch manufacture.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model course of work schematic diagram.
The specific embodiment
As shown in Figure 1, closed outline sheet metal component eject blanking die, is integrally formed the elasticity mould bases (1) of structure by cope match-plate pattern (1-1), lower bolster (1-2) and connecting plate (1-3).Connecting plate (1-3) is made arcuate structure.The widest distance H of arc of connecting plate (1-3) is greater than the distance h between cope match-plate pattern and lower bolster.
The upper patrix (2) of installing of cope match-plate pattern (1-1), the upper counterdie (5) that middle part is provided with groove (7), the upper alignment pin (4) of installing of counterdie (5) installed of lower bolster (1-2).The appearance profile of patrix (2) is identical with the appearance profile of groove (7).
During preparation, by upper die and lower die, use the hardness HRC56-60 steel plate after same Quenching Treatment to be cut simultaneously and processed by line, so the accuracy of manufacture is high, harmony is good, saves manufacturing cost.
After upper die and lower die coordinate unanimously, adopt welding or mechanical connection fixed form to be individually fixed on mould bases, form complete punching structure.
By elasticity mould bases, easy punching die upper die and lower die are connected to location, the horizontal free degree of constraint upper die and lower die, makes both on press machine, on lower table, do movement in vertical direction.As shown in Figure 2, metal blank (3) is placed on counterdie, after press machine punching press, along alignment pin, promotes metal blank, the die-cut sheet metal component getting off (6) nature is separated with metal blank.
Claims (3)
1. closed outline sheet metal component eject blanking die, it is characterized in that: cope match-plate pattern (1-1), lower bolster (1-2) and connecting plate (1-3) are integrally formed the elasticity mould bases (1) of structure, the upper patrix (2) of installing of cope match-plate pattern (1-1), the upper counterdie (5) that middle part is provided with groove (7), the upper alignment pin (4) of installing of counterdie (5) installed of lower bolster (1-2).
2. closed outline sheet metal component eject blanking die as claimed in claim 1, is characterized in that: the profile of patrix (2) is identical with the profile of groove (7).
3. closed outline sheet metal component eject blanking die as claimed in claim 1 or 2, is characterized in that: connecting plate (1-3) is arcuate structure.
