Abstract
The utility model discloses a stretching punching composite die. The stretching punching composite die comprises an upper die base, a lower die base, a convex die, a concave die and a guide column, wherein a punch is arranged below the middle of the upper die base, and an unloading rod and polyurethane blocks are sequentially arranged below the punch; the two sides of the upper end of the unloading rod are respectively provided with an unloading block, and one polyurethane block is arranged above each unloading block. The novel stretching punching composite die is simple in structure and convenient to manufacture and used, the number of working procedures is reduced, and working efficiency is improved.
Description
Technical field
The utility model relates to a kind of stretching punching composite die.
Background technology
General mould manufacturer, when some steel tubular goods of batch production, generally can relate to and stretching and punching technology, if the traditional handicraft of utilization, stretching and punching are carried out respectively in two molds, are subject to the restriction of production equipment ability, are difficult to meet foreign trader's delivery requirements.Though if be designed to the requirement that progressive die that automaticity is higher can meet schedule of deliveries, because the mould of design cannot ownly be produced at all, be unfavorable for the raising of the performance of enterprises, and comparatively huge mould there is no suitable punch press to process yet.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of new stretching punching composite die, and it is simple in structure, manufactures easy to usely, has reduced operation number, has improved production efficiency.
A stretching punching composite die, comprises upper bolster, die shoe, punch, die and guide pillar, and below, upper bolster middle part is provided with drift, and drift below is provided with discharge arm and polyurethane block successively; Both sides, discharge arm upper end are respectively provided with a unloading block, and each unloading block top is provided with a polyurethane block.
Stretching punching composite die provided by the utility model is simple in structure, manufacture easy to use, compound by original technique is carried out, reduced operation number, improved production efficiency.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below.
Fig. 1 is the structural representation of the disclosed a kind of punching composite die that stretches of the utility model embodiment.
1, upper bolster 2, die shoe 3, punch 4, die 5, guide pillar
6, drift 7, discharge arm 8, unloading block 9, polyurethane block 10, workpiece.
The specific embodiment
Below in conjunction with accompanying drawing, the technical scheme in the utility model embodiment is clearly and completely described.
The utility model provides a kind of new stretching punching composite die, and it is simple in structure, manufactures easy to usely, has reduced operation number, has improved production efficiency.
As shown in Figure 1, a kind of stretching punching composite die, comprises upper bolster 1, die shoe 2, punch 3, die 4 and guide pillar 5, and upper bolster 1 below, middle part is provided with drift 6, and drift 6 belows are provided with discharge arm 7 and polyurethane block 9 successively; Discharge arm 7 both sides, upper end are respectively provided with a unloading block 8, and each unloading block 8 top is provided with a polyurethane block 9.
Mould is fixed on and on punch press, carries out work, first the good semi-finished product workpiece 10 of stretching cropping is inserted in stretching convex die 3, along with stretching die 4 declines, itself and stretching convex die 3 actings in conjunction, gradually semi-finished product workpiece 10 base sections are drawn into taper, be near completion to tensioning member, drift 6 has contacted bottom punching with semi-finished product workpiece 10 bottoms, along with slider of punch continues to decline, stretching die 4 contacts completely with stretching convex die 3, 8 pairs of half finished work-pieces 10 of unloading block are smoothed, proofread and correct, the workpiece 10 that whole shaping is good is also proofreaied and correct, whole stretching → the punch process of part completes.Press slide rises, the polyurethane block 9 of unloading block 8 tops promotes unloading block 8 the good workpiece 10 of stretching punching is released to die cavity under elastic force effect, meanwhile, the polyurethane block 9 of discharge arm 7 belows is driving discharge arm 7 that die-cut good waste material is released to die 4 holes under elastic force effect, and mould proceeds to next operation cycle.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all modifications of making within spirit of the present utility model and on an equal basis conversion, within all should dropping on protection domain of the present utility model.
