Bearing steel pipe cooling device

Abstract

The invention discloses a bearing steel pipe cooling device. The bearing steel pipe cooling device comprises a cooling box, the top of the cooling box is of an opening structure, four supporting columns are fixedly installed at the bottom of the cooling box, a feeding port and a discharging port are formed in the inner walls of the two sides of the cooling box separately, twelve material guiding rollers are arranged in the cooling box at equal intervals, a feeding guide plate located below the feeding port is fixedly installed on one side of the cooling box, a discharging guide plate is fixedly installed on the side, away from the feeding guide plate, of the cooling box, the discharging guide plate is located below the discharging port, the feeding guide plate and the discharging guide plate are obliquely arranged, and twelve mounting holes are formed in the inner wall of one side of the cooling box at equal intervals. The bearing steel pipe cooling device is reasonable in design and good in practicability, a plurality of bearing steel pipes can be conveyed, the bearing steel pipes are effectively cooled in the conveying process, the working efficiency is improved, cooling water can be recycled, cooling water resources are saved, and the energy-saving effect is achieved.

Description

technical field [0001] The invention relates to the technical field of cooling equipment, in particular to a bearing steel pipe cooling device. Background technique [0002] Bearing steel pipe refers to hot-rolled or cold-rolled seamless steel pipe for the manufacture of ordinary rolling bearing rings. The outer diameter of the steel pipe is 25-180 mm and the wall thickness is 3.5-20 mm. It is divided into two types: ordinary precision and high precision. Bearing steel is used to make balls, rollers and bearing rings. Bearings are under great pressure and friction during work, so bearing steel is required to have high and uniform hardness and wear resistance, as well as high elasticity Limit, in the process of processing the bearing steel pipe, heat treatment is required, and the bearing steel pipe after heat treatment needs to be cooled down before the next processing procedure can be carried out. [0003] However, in the prior art, the commonly used cooling method is to i...

Problems solved by technology

[0003] However, in the prior art, the commonly used cooling method is to immerse the processed bearing steel pipes in the water tank. A large number of bearing steel pipes are piled up together, and the cooling effect is relatively poor. It is necessary to put the steel pipes into the water tank and then take them out. It t
