Roller internal water cooling device for rolling mill accessory machining

Abstract

The invention discloses a roller internal water cooling device for rolling mill accessory machining. The cooling device comprises a machine body; a base is fixedly mounted at the bottom of the machinebody; a workbench is arranged at the top of the machine body. A pressing plate is arranged at the top of the workbench. A water tank is arranged in the machine body; a conveying belt is arranged in the workbench. Roller clamping grooves are formed in the surface of the conveying belt. Two belt wheels are rotationally connected to the two sides of the interior of the conveying belt. A motor box isarranged in the middle in the conveying belt; a motor is arranged in the motor box; a motor shaft is arranged at one end of the motor; by means of a circulating water pump, water in the water tank can be pumped through the circulating water pump and then sprayed out of a water spraying head through a roller inserting rod, so that water cooling treatment is conducted on the interior of the hollowroller, the sprayed water is filtered through the water filtering plate and falls back to the water tank again, the circulating water cooling effect is achieved, and consumption of water resources isgreatly reduced.

Description

technical field [0001] The invention relates to the technical field of rolling mill accessories, in particular to a roll internal water cooling device for processing rolling mill accessories. Background technique [0002] Rolling mill is the equipment that realizes the metal rolling process. It generally refers to the equipment that completes the whole process of rolling material production. It is mainly composed of unwinding machine, rolling system, drive system, hydraulic system, control system, and roll removal device. Supports the roll and keeps the roll in a fixed position in the stand. The work load of the roll bearing is heavy and changes greatly, so the bearing friction coefficient is required to be small, have sufficient strength and rigidity, and be easy to replace the roll. Different rolling mills use different types of roll bearings. [0003] The roll is the main working part and tool for continuous plastic deformation of the metal on the rolling mill. The rol...

Problems solved by technology

[0004] Due to the solid structure inside the current roll, not only the heat dissipation effect of the roll is not good, but also the weight is too large, which greatly increases the overall weight of the equipment, so there is a hollow roll. However, when processing the hollow roll , the temperature of the roll is also high, which greatly reduces the processing efficiency of the roll, so it is necessary to cool the roll
