Abstract

The utility model discloses a cold-rolling mill coil rod structure, which comprises a core rod body, wherein one end of the coil rod body is provided with a connection part; the core rod body comprises a cylindrical section and a conical section; a transition section is arranged between the cylindrical section and the conical section; and the transition section and the connection part between the cylindrical section and the conical section are in a smooth arc-shaped structure. The cold-rolling mill coil rod structure is additionally provided with the transition section of the smooth arc-shaped structure, small resistance is generated due to the fact that the arc-shaped transition is adopted in the cold-rolling process, and the rolling feeding is big. The cold-rolling mill coil rod structure has the advantages of simple structure, easiness in realization and high production efficiency.

Description

A kind of cold-rolling mill mandrel structure
Technical field
The utility model relates to a kind of rolling tool technical field of cold-rolling mill, relates in particular to a kind of cold-rolling mill mandrel structure.
Background technology
plug is the vitals of cold-rolling mill, in use, plug and pass are used in conjunction with, can make rolling pipe reach by the process of design the purpose that tube reducing subtracts wall, produce into flat pipe, see also shown in Figure 1, Fig. 1 is the structural representation of traditional cold-rolling mill plug, traditional cold-rolling mill plug comprises plug body 10, one end of described plug body 10 is provided with connecting portion 11, and described plug body 10 comprises cylindrical section 12 and conical section 13, described cylindrical section 12 directly carries out transition to conical section 13, produce larger resistance when making like this in cold-rolled process by conical section 13 to cylindrical section 12 transition, cause the feeding of cold-rolling mill very little, production efficiency is lower.
The utility model content
The purpose of this utility model is to provide a kind of cold-rolling mill mandrel structure, its have simple in structure, be easy to realize, operation of rolling resistance is little and production efficiency is high characteristics, to solve the problem that in prior art, the cold-rolling mill mandrel structure exists.
For reaching this purpose, the utility model by the following technical solutions:
A kind of cold-rolling mill mandrel structure, it comprises the plug body, one end of described plug body is provided with connecting portion, and described plug body comprises cylindrical section and conical section, wherein, also be provided with changeover portion between described cylindrical section and conical section, the connecting portion between described changeover portion and cylindrical section and conical section is level and smooth arcuate structure.
The beneficial effects of the utility model are, described cold-rolling mill mandrel structure is compared with prior art set up the changeover portion of level and smooth arcuate structure, like this in cold-rolled process owing to adopting arc-shaped transition, the resistance that produces is little, it is rolling that to send nature to just large, not only simple in structure, be easy to realize, and production efficiency is high.
Description of drawings
Fig. 1 is the structural representation of traditional cold-rolling mill plug;
Fig. 2 is the structural representation of the cold-rolling mill plug that provides of the utility model specific embodiment 1.
The specific embodiment
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.
See also shown in Figure 2ly, Fig. 2 is the structural representation of the cold-rolling mill plug that provides of the utility model specific embodiment 1.
In the present embodiment, a kind of cold-rolling mill mandrel structure comprises plug body 20, one end of described plug body 20 is provided with connecting portion 21, and described plug body 20 comprises cylindrical section 22 and conical section 23, also be provided with changeover portion 24 between described cylindrical section 22 and conical section 23, the connecting portion between described changeover portion 24 and cylindrical section 22 and conical section 23 is level and smooth arcuate structure.
Above-mentioned cold-rolling mill plug is set up the changeover portion 24 of level and smooth arcuate structure, like this in cold-rolled process owing to adopting arc-shaped transition, the resistance of generation is little, it is rolling that to send nature to just large, not only simple in structure, be easy to realize, and production efficiency is high.
Above embodiment has just set forth basic principle of the present utility model and characteristic; the utility model is not limited by above-mentioned example; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
