Description
Technical field
The utility model relates to pipe fitting production technical field, is specifically related to a kind of small-sized pipe fitting expansion gear.
Background technology
In prior art, midget tube end of body shaping protruding time, manual employing equipment carries out punching press, although it is so can punch forming, but owing to adopting craft, its inefficiency, simultaneously stamping forming poor effect.
Summary of the invention
For the problems referred to above, the utility model provides a kind of structure simple, reasonable in design, the small-sized pipe fitting expansion gear that expansion effect is good, efficiency is high.
The utility model is achieved through the following technical solutions:
Small-sized pipe fitting expansion gear, comprise die shoe, upper bolster, die shoe is provided with locating piece, and be arranged at the die that locating piece can move in the horizontal direction, the middle part of die offers die hole, the inwall of die hole is provided with arc-shaped concave structure, described die shoe, locating piece, die offers the pilot hole connected;
Framed on upper bolster is provided with, and by the upper framed guide post be locked on upper bolster, described guide post coordinates with above-mentioned pilot hole, the middle part of guide post is bending guiding surface; Upper bolster is fixedly installed mould post, this mould post stretch into framed in and be arranged with the upper module that can move along mould post, the first elastic component by the two compressing is provided with between upper module and upper bolster, described upper module is provided with L-type punch, is provided with the convex surface adapted with above-mentioned arc-shaped concave structure at the die end outer wall of punch.
Have employed such scheme, small-sized pipe fitting is positioned on locating piece, upper bolster declines, L-type punch enters in the die hole of die, decline after putting in place, L-type punch stops declining, and due to the setting of the first elastic component, upper bolster can be oppressed under the first elastic component makes mould post continue and is advanced in die hole, bend the effect of guiding surface in the middle part of guide post under, guide post promotes die and moves to centre, because die hole arc concave structure is with under the cooperation of punch die end outer wall convex surface, bulging is carried out to small-sized pipe fitting, thus completes the expansion process of small-sized pipe fitting; When upper bolster is up, owing to bending the effect of guiding surface in the middle part of guide post, die is mobile laterally to be resetted, and mould post rises between L-type punch, L-type punch lower end purse up, and small-sized like this pipe fitting just can from landing mould post.The utility model structure is simple, reasonable in design, the advantage that expansion effect is good, efficiency is high.
Further, described L-type punch is arranged on upper module by rotating shaft is rotating, and between L-type module and upper module, be provided with the second elastic component supporting L-type module.
Further, the resigning hole be connected with die hole is offered in the middle part of described locating piece.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the small-sized pipe fitting adopting the utility model to complete;
Detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As Fig. 1,2, small-sized pipe fitting expansion gear, comprise die shoe 1, upper bolster 2, die shoe is provided with locating piece 3, and be arranged at the die 4 that locating piece can move in the horizontal direction, the middle part of die offers die hole 5, and the inwall of die hole is provided with arc-shaped concave structure 6, die shoe, locating piece, die offers the pilot hole 7 connected;
On upper bolster is provided with framed 8, and by the upper framed guide post 9 be locked on upper bolster, guide post coordinates with above-mentioned pilot hole, and the middle part of guide post is bending guiding surface 10; Upper bolster is fixedly installed mould post 11, this mould post stretch into framed in and be arranged with the upper module 12 that can move along mould post, the first elastic component 13 by the two compressing is provided with between upper module and upper bolster, upper module is provided with L-type punch 14, is provided with the convex surface 15 adapted with above-mentioned arc-shaped concave structure at the die end outer wall of punch.
Wherein, L-type punch is arranged on upper module by rotating shaft 16 is rotating, and between L-type module and upper module, be provided with the second elastic component 17 supporting L-type module.Wherein the first elastic component, the second elastic component can be spring.The resigning hole 18 be connected with die hole is offered, for accommodating small-sized pipe fitting 19 in the middle part of locating piece.
The course of work of the present utility model: small-sized pipe fitting is positioned on locating piece, upper bolster declines, L-type punch enters in the die hole of die, undertaken spacing by limited post 20, after such decline puts in place, L-type punch stops declining, and due to the setting of the first elastic component, upper bolster can be oppressed under the first elastic component makes mould post continue and is advanced in die hole, bend the effect of guiding surface in the middle part of guide post under, guide post promotes die and moves to centre, because die hole arc concave structure is with under the cooperation of punch die end outer wall convex surface, bulging is carried out to small-sized pipe fitting, thus complete the expansion process of small-sized pipe fitting, namely at the shaping protuberance 21 of small-sized pipe fitting end.
The utility model is not limited to described embodiment; those skilled in the art is not departing from spirit of the present utility model namely openly in scope; still can do some revise or change, therefore the scope that rights protection scope of the present utility model limits with claims is as the criterion.
