Abstract

The utility model discloses a mill mixer which is convenient to process. The mill mixer comprises a cylinder body[1] and a roll shaft[2] which are connected through interference fit and welding. A central hole[4]is arranged at the axis of the roll shaft[2], and a liquid inlet[5]and a liquid outlet[6] communicated with the central hole[4]are arranged on the roll shaft[2] in the radial direction. The mill mixer is characterized in that a cooling groove[3], a liquid intake ring groove[7] communicated with the cooling groove[3] and the liquid inlet[5], and a liquid discharge ring groove[8]communicated with the cooling groove[3]and the liquid outlet[6] are arranged on the roll shaft[2]. The mill mixer is simple in structure, easy to process and good in cooling performance and can fully satisfy production technical requirements.

Description

A kind of mill roller

Technical field:

The utility model relates to a kind of mill, specifically a kind of mill roller.

Background technology:

At present the mill roller generally is to communicate the formation cooling structure at cylindrical shell upper edge axis direction drilling deep hole (cooling bath) and rat holing with inlet opening, fluid hole on the roll shaft.And drilling deep hole, inclined hole processing difficulties, complexity, cost is higher.

Summary of the invention:

The purpose of this utility model provides a kind of mill roller easy to process.

The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of mill roller, it comprises cylindrical shell, the roll shaft that is connected with welding manner by interference fit, the axle center of roll shaft is provided with centre bore, the footpath upwards is provided with inlet opening and the fluid hole that communicates with centre bore, the fluid annular groove that the roll shaft outer round surface is provided with cooling bath, the feed liquor annular groove that communicates with cooling bath and inlet opening and communicates with cooling bath and fluid hole.

The utility model is for improving cooling effect, and described inlet opening and fluid hole are through hole.

The utility model is for improving cooling effect, and the different each other friendship of the axis of inlet opening and fluid hole is preferably 90 degree.

Because adopt technique scheme, the utility model has been realized goal of the invention preferably, it is simple in structure, handling ease, and cooling performance is good, can satisfy the requirement of production technology fully.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of the utility model roll shaft;

Fig. 3 is the A-A cutaway view of Fig. 2;

Fig. 4 is the B-B cutaway view of Fig. 2.

The specific embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing.

By Fig. 1, Fig. 2, Fig. 3, Fig. 4 as can be known, a kind of mill roller, it comprises cylindrical shell 1, the roll shaft 2 that is connected with welding manner by interference fit, the axle center of roll shaft 2 is provided with centre bore 4, the footpath upwards is provided with inlet opening 5 and the fluid hole 6 that communicates with centre bore 4, the fluid annular groove 8 that roll shaft 2 outer round surface are provided with cooling bath 3, the feed liquor annular groove 7 that communicates with cooling bath 3 and inlet opening 5 and communicate with cooling bath 3 and fluid hole 6.

The utility model is for improving cooling effect, and described inlet opening 5 and fluid hole 6 are through hole.

The utility model is for improving cooling effect, and the different each other friendship of the axis of inlet opening 5 and fluid hole 6 is preferably 90 degree.

Like this, cooling fluid is identical in the shortest flow process of each cooling bath 3, reaches best cooling effect.

The concrete course of work of the present utility model is: cooling fluid flows into from feed tube 9, intercepted by seal 10, cooling fluid can only be passed through inlet opening 5, flow into feed liquor annular groove 7, flow into the cooling bath 3 of roll shaft 2 outer round surface again, flow into centre bore 4 by fluid annular groove 8, fluid hole 6 again, cooling fluid is sent outside the roll shaft 2, realize hot and cold exchange, make roller maintain certain temperature by cooling fluid.
