Abstract
The utility model relates to an auxiliary necking jig which comprises a jig body, wherein a shrinkage cavity is formed in the center of the jig body and is tapered; the jig body is cylindrical; a chamfer is formed in the opening part of the shrinkage cavity; and the shrinkage cavity is a through hole. With the adoption of the structure, a workpiece is pressed into the shrinkage cavity, so that the necking effect of a product is realized; and the auxiliary necking jig is simple in structure and convenient to operate and can improve the production efficiency of the product and reduce the production cost of an enterprise.
Description
Technical field
The utility model relates to a kind of tool in field of machining, especially relates to a kind of reducing auxiliary fixture.
Background technology
In processing technology, reducing is by preshaped good cylindrical element or pipe fitting blank, a kind of forming process of its oral area being dwindled by necking die.The application of reducing operation is more extensive, can be used for the shaping of the parts such as cartridge case, gun shell, steel gas bottle, vertical pipe of bicycle frame, saddle saddle pipe.To elongated tubulose class part, sometimes with reducing, replace pull and stretch can obtain better effect.At present, necking die complex structure in machinery industry, is used very inconvenient.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of simple in structure, the convenient reducing auxiliary fixture that uses and can enhance productivity.
The technical scheme in the invention for solving the technical problem is: a kind of reducing auxiliary fixture, and described tool comprises tool body, in tool body center, is provided with shrinkage cavity, described shrinkage cavity is tapered.
Further concrete, described tool body is cylindric.
Further concrete, described shrinkage cavity peristome is provided with chamfering.
Further concrete, described shrinkage cavity is through hole.
The beneficial effects of the utility model are: after having adopted said structure, by workpiece is pressed onto in shrinkage cavity and is reached the effect of product reducing, it is simple in structure, easy to operate, can improve the production efficiency of product, reduce the production cost of enterprise.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sectional structure schematic diagram of the present utility model.
In figure: 1, tool body; 2, shrinkage cavity; 3, taper.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
A reducing auxiliary fixture as shown in Figure 1, described tool comprises tool body 1, in tool body 1 center, is provided with shrinkage cavity 2, described shrinkage cavity 2 tapered 3; Described tool body 1 is cylindric; Described shrinkage cavity 2 peristomes are provided with chamfering; Described shrinkage cavity 2 is through hole.
In operation time,, be placed on the workpiece that needs reducing on tool, by press, workpiece one end is pressed in shrinkage cavity 2, and the inner conical surface by shrinkage cavity 2 carries out reducing to workpiece, and whole jig structure is simple, easy to operate, can improve the production efficiency of product.
It is emphasized that, it is more than better implementation column of the present utility model, not the utility model is done to any type of restriction in appearance, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
