CN202571120U - Core roll for gear forgings - Google Patents

Abstract

The utility model belongs to the field of forging dies, and in particular relates to a core roll for gear forgings. The core roll for gear forgings comprises a roll shaft and a roll body, wherein a cylindrical roll body in the middle of the roll body is provided with an inward inner groove, and the outer side of the inner groove adopts an arc design. Through adopting a design on the groove in the middle of the core roll, while the product performance is not affected, a lot of materials can be saved, and the production cost of enterprises can be reduced.

Description

A kind of gear forgings core roller

Technical field

The utility model belongs to the forging mould applications, specifically relates to a kind of gear forgings core roller.

Background technology

Gear forgings is an industry forging commonly used, and the core roller of producing gear forgings now adopts traditional core roller, and the materials amount is big, has increased the enterprise production cost.

Therefore, design and under the situation that guarantees properties of product, minimizing to produce materials, reduce a kind of gear forgings core roller of enterprise production cost, the problem that the inventor faced just for the deficiency that overcomes above-mentioned technology.

Summary of the invention

To the deficiency of prior art, the purpose of the utility model provides a kind of gear forgings core roller, and it is easy to operate, uses simply, under the situation that guarantees properties of product, reduces and produces materials, reduces the enterprise production cost, and extraordinary practical value is arranged.

The utility model solves the technical scheme that its technical problem adopted: a kind of gear forgings core roller, and bag roll shaft and roll body, the middle part cylinder roll body of said roll body is provided with inner groovy to the inside, and the outside of inner groovy is designed for circular arc.

The beneficial effect of the utility model is:

1, adopts groove design through core roller middle part,, can practice thrift a large amount of materials, lowered the production cost of enterprise not influencing properties of product simultaneously.

Description of drawings

Fig. 1 is that the utility model improves the pre-structure sketch map.

Fig. 2 is that the utility model improves the back structural representation.

Description of reference numerals: 1-roll shaft; The 2-roll body; The 3-inner groovy.

The specific embodiment

Below in conjunction with specific embodiment, further set forth the utility model, should be understood that these embodiment only be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values drop on application appended claims institute restricted portion equally.

Improve the pre-structure sketch map and improve the back sketch map like Fig. 1, a kind of gear forgings core roller shown in Figure 2, bag roll shaft 1 and roll body 2, the middle part cylinder roll body of said roll body 2 is provided with inner groovy 3 to the inside; The outside of inner groovy 3 is designed for circular arc, when using the utility model, and the material of the part of core roller inner groovy 3 both sides for saving; Adopt groove design through core roller middle part; Not influencing properties of product simultaneously, can practice thrift a large amount of materials, lowered the production cost of enterprise.
