Abstract

The utility model discloses an alloy roller collar mold core. The alloy roller collar mold core comprises a mold core body, wherein the left end face of the mold core body is provided with blind holes along the axle; and the opening end of the blind hole is provided with an end cover. The alloy roller collar mold core has the advantages that as the blind holes are formed on the mold core body, the weight of the whole mold core body is effectively reduced, the mold core can be carried or used conveniently, the labor intensity of workers is lowered, and the production efficiency is improved.

Description

The ring-like core of a kind of alloy roller

Technical field

The utility model relates to the ring-like core of a kind of alloy roller.

Background technology

Carbide roll ring has good comprehensive mechanical property, high-flexural strength, high rigidity, good impact flexibility, in addition its intrinsic rotproofness and mechanical behavior under high temperature, make carbide roll ring have excellent wearability, in the high-speed wire rolling process, its single groove steel transportation amount is far above chilled cast iron or high-speed steel roll.The mould that the ring-like core of alloy roller uses when being the alloying collars, the core external diameter larger to some bodily forms has 240mm, and long 290mm is very heavy, is unfavorable for carrying and the use of core mold.

The utility model content

The purpose of this utility model is to provide a kind of alloy roller ring-like core, can effectively solve the existing ring-like core weight of alloy roller larger, is unfavorable for the problem of carrying and the use of core mold.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: the ring-like core of a kind of alloy roller, comprise the core body, and have blind hole along axis on the left side of described core body, the openend of described blind hole is provided with end cap.

Preferably, the left side of the outer surface of described end cap and core body is in the same plane; So that the external form of this core is consistent with existing core external form, do not need to change in use the equipment of other cooperations.

Preferably, the leading portion of described blind hole is truncated cone-shaped, and the leading portion of described end cap and blind hole is suitable; Be convenient to end cap and fix, increase the contact area of end cap and blind hole.

Compared with prior art, the utility model has the advantages that: because have blind hole on the core body, effectively reduce the weight of whole core body, be beneficial to carrying and the use of core, reduced workman's labour intensity, improved production efficiency.

Description of drawings

Fig. 1 is the explosive view of the ring-like core of a kind of alloy roller of the utility model.

The specific embodiment

Consulting Fig. 1 is the embodiment of the ring-like core of a kind of alloy roller of the utility model, the ring-like core of a kind of alloy roller, comprise core body 1, have blind hole 2 along axis on the left side of described core body 1, the openend of described blind hole 2 is provided with end cap 3, the left side of the outer surface of described end cap 3 and core body 1 is in the same plane, and the leading portion of described blind hole 2 is truncated cone-shaped, and described end cap 3 is suitable with the leading portion of blind hole 2.

End cap 3 can utilize interference fit to fill in the blind hole 2, and the core with general during use is the same, but because middle being emptied, it is light a lot of that weight is wanted, and is beneficial to carrying and the use of core, reduced workman's labour intensity, improved production efficiency.

The above only is specific embodiment of the utility model, but technical characterictic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification all are encompassed among the claim of the present utility model.
