Abstract
The utility model discloses a drawing die for U-iron, which comprises an upper template (1), a drawing female die (4), a concave-convex die (6), a lifting press plate (7) and a lower template (8). The drawing female die (4) is fixed to the upper template (1) and the concave-convex die (6) is fixed to the lower template (8). The lifting press plate (7) is sleeved on the outside of the concave-convex die (6). The upper end face of the lifting press plate (7) is equipped with an annular boss (7.1) close to one side of the concave-convex die (6) for compressing the arc segment of the opening end of the U-iron. By utilizing the drawing die for U-iron, the force balance at the arc segment of the opening end of the U-iron during the drawing process is realized.
Description
Technical field
The utility model relates to a kind of drawing die of the U of being used for iron.
Background technology
U iron is a kind of electroacoustic accessory, is through drawing die machine-shaping.The drawing die that is used for U iron of prior art comprises cope match-plate pattern, knockout rod, dnockout bedding core, stretching die, concavo-convex mould, lifts pressing plate and lower bolster.The mode that matches through guide pillar and guide pillar hole between described cope match-plate pattern and the lower bolster is installed.Described stretching die is fixed on the cope match-plate pattern, and described knockout rod is fixed on the cope match-plate pattern.Described dnockout bedding core is located in the described stretching die, and the lower surface of dnockout bedding core is used for the bottom of moulding U iron.Described concavo-convex mould is fixed on the lower bolster.The described pressing plate of lifting is linked in outside the concavo-convex mould, and this is lifted pressing plate and is used to accomplish product stripping.There is following defective in the drawing die that is used for U iron of prior art: U iron is at drawing process; The one side of the openend arc section of U iron receives the extruding of stretching die port arc surface; And another side is a free state; Promptly do not hinder, therefore tend to reduce the qualification rate of product owing to receive force unbalance to produce U iron openend arc section because of the wrinkling phenomenon of unstability.
The utility model content
The technical problem that the utility model will solve is, the drawing die that is used for U iron of arc section stress balance of the openend of a kind of U of making iron U iron in drawing process is provided.
The technical solution of the utility model is, a kind of drawing die that is used for U iron with following structure is provided, and comprises cope match-plate pattern, stretching die, concavo-convex mould, lifts pressing plate and lower bolster; Described stretching die is fixed on the cope match-plate pattern, and described concavo-convex mould is fixed on the lower bolster, and the described pressing plate of lifting is linked in outside the concavo-convex mould; Described upper surface of lifting pressing plate is provided with and is used to compress the annular boss of U iron openend arc section near the one side of concavo-convex mould.
After adopting above structure, the drawing die that the utility model is used for U iron compared with prior art has the following advantages:
Because the upper surface of lifting pressing plate of the drawing die that is used for U iron of the utility model is provided with and is used to compress the annular boss of U iron openend arc section near the one side of concavo-convex mould; Therefore U iron is in the process that stretches; The one side of the openend arc section of U iron receives the extruding of stretching die port arc surface, and another side receives compressing of the annular boss lifted on the pressing plate upper surface, makes U iron port two sides stress balance; Therefore can avoid because of the wrinkling phenomenon of unstability, improve the qualification rate of product.
Description of drawings
Fig. 1 is the structural representation of U iron before stretching.
Fig. 2 is the structural representation of U iron after stretching.
Fig. 3 is the structural representation that the utility model is used for the drawing die of U iron.
Shown in the figure: 1, cope match-plate pattern, 2, knockout rod, 3, the dnockout bedding core, 4, the stretching die, 5, upper mounted plate, 6, concavo-convex mould, 7, lift pressing plate, 7.1, annular boss, 8, lower bolster, 9, bottom plate, 10, lift pressure device, 11, U iron.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
Please join Fig. 1, Fig. 2 and shown in Figure 3, the drawing die that is used for U iron of the utility model comprises cope match-plate pattern 1, knockout rod 2, dnockout bedding core 3, stretching die 4, concavo-convex mould 6, lifts pressing plate 7 and lower bolster 8.The mode that matches through guide pillar and guide pillar hole between described cope match-plate pattern 1 and the lower bolster 8 is installed.Described stretching die 4 is fixed on the cope match-plate pattern 1 through upper mounted plate 5, and described knockout rod 2 is fixed on the cope match-plate pattern 1.Described dnockout bedding core 3 is located in the described stretching die 4 and this dnockout bedding core 3 is fixed on the lower end of knockout rod 2, and the lower surface of described dnockout bedding core 3 is used for the bottom of moulding U iron 11.Described concavo-convex mould 6 is fixed on the lower bolster 8 through bottom plate 9.The described pressing plate 7 of lifting is linked in outside the concavo-convex mould 6, and described upper surface of lifting pressing plate 7 is provided with and is used to compress the annular boss 7.1 of U iron openend arc section near the one side of concavo-convex mould.Describedly lift pressing plate 7 and lift pressure device 10 and be connected.
When the upper die and lower die matched moulds carries out the stretching of U iron; The one side of the openend arc section of U iron receives the extruding of stretching die port arc surface; Another side receives compressing of the annular boss lifted on the pressing plate upper surface; Make U iron port two sides stress balance, therefore can not produce the wrinkling phenomenon of unstability, guarantee the qualification rate of product.
