Abstract

A barrel-shaped spring die comprises a base, a shaft pin and die pieces, wherein the base is connected with the shaft pin through a fastener. The shaft pin is provided with a plurality of the die pieces in a penetrating mode, the die pieces are of ring-shaped structures, the outer ring diameter of the die pieces is gradually reduced from the middle of the shaft pin to the two sides of the shaft pin, and the die pieces are provided with a plurality of round holes. The barrel-shaped spring die has the advantages that the rolling process of a barrel-shaped spring can be finished at a time, and the work efficiency is improved.

Description

Camber floating die assembly

Technical field

The utility model relates to spring and manufactures field, particularly a kind of floating die assembly.

Background technology

Convexity spring is the spring that outside a kind of middle part, ring diameter is greater than ring diameter outside both sides, particularity due to its structure, having caused wind spring to complete rear spring mould can not take out, so adopt of prior art first made respectively two tower-like springs more, the mode of production of welding again, reduced production efficiency, due to the volume of floating die assembly, substantially equal the volume in the ring space that surrounds in spring simultaneously, so the general volume of the mould using is larger, comparatively heavy, not only improved the cost of mould, and employee's physical load when having increased spring and manufacturing, further reduced production efficiency.

Summary of the invention

The purpose of this utility model is in order to address the above problem, and has designed a kind of camber floating die assembly.Specific design scheme is:

A kind of camber floating die assembly, comprise base, pivot pin, matrix, described base is connected with described pivot pin by securing member, on described pivot pin, be installed with a plurality of matrixs, described matrix is structure in the form of a ring, and by the centre of pivot pin, the both sides to described pivot pin reduce the outer ring diameter of described matrix successively, and described matrix is provided with a plurality of circular holes.

The center of described matrix is provided with jack.

The camber floating die assembly obtaining by technique scheme of the present utility model, its beneficial effect is:

Whole mould can split into a pivot pin and a plurality of matrix, after completing, wind spring can from camber spring, take out matrix and pivot pin, wind spring of camber spring is completed, and can by changing the pivot pin of different length and the matrix of use different-diameter and quantity, complete the making of all size camber spring, enhance productivity.

Described matrix is provided with a plurality of circular holes, and not only reduce mould and produced the raw material using, and owing to having alleviated the weight of mould, thereby reduced the work load of employee when spring is produced.

Accompanying drawing explanation

Fig. 1 is the structural representation of camber floating die assembly described in the utility model;

Fig. 2 is the structural representation of matrix described in the utility model;

In figure, 1, base; 2, pivot pin; 3, matrix; 4, securing member; 5, circular hole; 6, jack.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is specifically described.

Fig. 1 is the structural representation of camber floating die assembly described in the utility model; Fig. 2 is the structural representation of matrix described in the utility model, as shown in Figure 1 and Figure 2, a kind of camber floating die assembly, comprise base 1, pivot pin 2, matrix 3, it is characterized in that, described base 1 is connected with described pivot pin 2 by securing member 4, on described pivot pin 2, be installed with a plurality of matrixs 3, described matrix 3 is structure in the form of a ring, and the outer ring diameter of described matrix 3 by the centre of pivot pin 2, the both sides to described pivot pin 2 reduce successively, described matrix 3 is provided with a plurality of circular holes 5.

The center of described matrix 3 is provided with jack 6.

While producing spring, described matrix 3 is penetrated in order in described pivot pin 2 and by securing member 4 and fixed, then the mould of putting on is placed on and on spring coiling machine, completes wind spring, again mould is taken off, loosening fasteners 4, by base 1, extract pivot pin 2, then from the gap of spring, take out described matrix 3, complete the overall process of wind spring.

Technique scheme has only embodied the optimal technical scheme of technical solutions of the utility model; those skilled in the art have all embodied principle of the present utility model to some changes that wherein some part may be made, within belonging to protection domain of the present utility model.
