Abstract
The utility model discloses a tensile mould of small -size station belongs to mould technical field, it contains mould, lower mould, punching pin, blanking hole, buffer board, elastic component, the several punching pin be connected with last mould, the lower mould on be equipped with the blanking hole that several and punching pin correspond each other, the buffering sleeve -board establish on the punching pin, and the both ends of buffer board are passed through the elastic component and are connected with the upper die base of last mould. Its structural design is reasonable, convenient operation, stability in the time of effectually ensureing the punching pin motion to the atress of buffering punching pin can prolong the life of punching pin, has reduced the cost of changing the punching pin, still can improve the efficiency of punching press greatly.
Description
Technical field
The utility model relates to technical field of mold, is specifically related to a kind of drawing die of small-sized station.
Background technology
Mould makes blank become under external force to have the instrument of the product of given shape and size.Be widely used in stamping-out, die forging, cold-heading, extruding, metallic sintered products compacting, compression casting, and in the compression moulding of goods such as engineering plastics, rubber, pottery or the formed machining of injection moulding.Mould has specific profile or cavity shape, and the contour shape that application has cutting edge can make blank be separated (stamping-out) by outline line shape.Application cavity shape can make blank obtain corresponding three-dimensional shape.Mould generally comprises dynamic model and cover half (or punch and die) two parts, the two partable.Take out product time separately, make blank inject mold cavity when closing up and be shaped.Mould is precision instrument, complex-shaped, bears the expansive force of blank, all has higher requirements to structural strength, rigidity, case hardness, surface roughness and machining accuracy, and the development level that mould is produced is one of important symbol of machine-building level.
Have much little station in some hardware products, adding man-hour, punching pin length is very long, and diameter is less, and because cushion effect is comparatively large during punching press, punching pin can be made to be out of shape, constantly changing punching pin can increase processing cost, and can not solve the basic of punching pin distortion.
Summary of the invention
For the problems referred to above, the technical problems to be solved in the utility model is to provide the drawing die of small-sized station of a kind of reasonable in design, easy to operate, steady quality, long service life.
The drawing die of a kind of small-sized station of the present utility model, it comprises upper die and lower die, punching pin, material-dropping hole, buffer board, elastic component; Described several punching pines are connected with patrix; Described counterdie is provided with several material-dropping hole mutually corresponding with punching pin; Described buffer board is set on punching pin, and the two ends of buffer board are connected with the upper bolster of patrix by elastic component.
As preferably, the top of described material-dropping hole is straight barrel type, and the below of material-dropping hole is trapezoidal material-dropping hole.
As preferably, described buffer board is lamina or doubling plate.
As preferably, described elastic component is that several spring is socketed to form, and elasticity is large, not yielding.
During the utility model operation, when punching pin falls, buffer board follows punching pin, the stability of punching pin can be improved like this, the external force that buffering punching pin is subject at first, reduce deformation rate, improve the success rate of punching press, decrease the cycle changing punching pin simultaneously, reduce cost.
The beneficial effects of the utility model: its reasonable in design, easy to operate, effectively can guarantee stability when punching pin moves, and cushion the stressed of punching pin, the service life of punching pin can be extended, reduce the cost changing punching pin, also greatly can improve the efficiency of punching press.
accompanying drawing illustrates:
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is structural representation of the present utility model;
In figure:
Patrix 1, counterdie 2, punching pin 3, material-dropping hole 4, buffer board 5, elastic component 6.
detailed description of the invention:
As shown in Figure 1, this detailed description of the invention by the following technical solutions: it comprises patrix 1, counterdie 2, punching pin 3, material-dropping hole 4, buffer board 5, elastic component 6; Described several punching pines 3 are connected with patrix 1; Described counterdie 2 is provided with several material-dropping hole 4 mutually corresponding with punching pin 3; Described buffer board 5 is set on punching pin 3, and the two ends of buffer board 5 are connected with the upper bolster of patrix 1 by elastic component 6.
Wherein, the top of described material-dropping hole 4 is straight barrel type, and the below of material-dropping hole 4 is trapezoidal material-dropping hole.
Wherein, described buffer board 5 is lamina or doubling plate.
Described elastic component 6 is socketed to form for several spring, and elasticity is large, not yielding.
During the operation of this detailed description of the invention, when punching pin 3 falls, buffer board is followed punching pin 3 and is fallen, the stability of punching pin can be improved like this, the external force that buffering punching pin 3 is subject at first, reduce deformation rate, improve the success rate of punching press, decrease the cycle changing punching pin simultaneously, reduce cost.
This detailed description of the invention reasonable in design, easy to operate, effectively can guarantee stability when punching pin moves, and cushion the stressed of punching pin, the service life of punching pin can be extended, reduce the cost changing punching pin, also greatly can improve the efficiency of punching press.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
