Description

Water cooling roller with flow guide pipe

Technical Field

The utility model relates to a steel rolling mechanical equipment technical field especially relates to a take water-cooling roller of honeycomb duct.

Background

The roller bed is widely applied to a steel rolling production line, the rotary motion is converted into linear motion, high-temperature steel plates are conveyed, high temperature is generated on the surface of the roller body, and a method of introducing water into the inner cavity of the roller body to cool is adopted to prolong the service life of the roller body. The existing water-cooled roller generally adopts a hollow roller. The hollow part in the roller way is provided with a water inlet pipe, and the pipe diameter of the water inlet pipe is smaller than that of the hollow part in the roller way. The cooling water enters the roller way through the water inlet pipe and flows out of the roller way through the pipeline gap between the water inlet pipe and the hollow roller. The pressure difference between the inlet water and the return water pushes the cooling water to flow in the roller way and take away heat. The cooling roller table has a simple structure and is widely applied to various hot rolling production lines. But its cooling water is mostly the turbulent flow in the inside flow of roll table, causes the roll table cooling inhomogeneous, and the roll table not only bears radial temperature stress, still bears great axial temperature stress, has reduced the roll table life-span. Meanwhile, since the cooling water is unevenly distributed in the roller way, good dynamic balance performance cannot be ensured when the roller way runs at a high speed, and the roller way shakes. In order to improve the cooling effect, the flow of cooling water is often increased, which causes the waste of water resources.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

In the figure: take water-cooling roller of honeycomb duct, including roll body 1, spindle nose A2, spindle nose B3, its characterized in that: a flow guide pipe 4 is arranged in the roller body 1, hollow round tables are arranged at two ends of the flow guide pipe 4, a plurality of clamping plates 43 are uniformly distributed on the outer ring of each hollow round table, and a flow guide ring 41 is welded on the outer ring of the flow guide pipe 4; one end of the roller body 1 is welded with a shaft head A2, the other end of the roller body is welded with a shaft head B3, and a plurality of balance blocks 6 are uniformly distributed on the end faces of the shaft head A2 and the shaft head B3; fixing blocks 7 are welded in holes at two ends of the roller body 1 at two sides of the clamping plate 43; a water channel A21 is arranged in the shaft head A2, and an inner thread A22 is arranged at the inlet of the water channel A21; a water channel B31 is arranged in the shaft head B3, and an internal thread B32 is arranged at the outlet of the water channel B31; conical holes are formed at the joints of the shaft heads A2 and B3 and the hollow round platform of the draft tube 4.
