Description

Roller chamfering device with roller bearing seat free of disassembly

Technical Field

The utility model belongs to heavy roll lathe field especially relates to a roll chamfer device that roll bearing frame exempted from to demolish.

Background

The rolls are tools for plastically deforming a metal to be rolled, and roll a steel material by using a pressure generated when a pair or a group of rolls roll. There are different methods of classifying the rolls. The roller body is divided into a cylindrical shape and a non-cylindrical shape according to the shape of the roller body. And the working roll and the supporting roll are divided according to whether the rolled piece is contacted or not. The roller directly contacting the rolled piece is called a working roller; the roller which is arranged on the back or side of the working roller and does not directly contact with a rolled piece in order to increase the rigidity and the strength of the working roller is called a back-up roller. The mill is divided into a primary roll, a rough roll, a middle roll and a fine roll according to the used frame. According to the variety of rolled materials, the rolled materials are divided into plate and strip rollers, rail and beam rollers, wire rod rollers, pipe rollers and the like. And can be divided into a hot roll and a cold roll according to the state of a rolled piece during rolling. The rolls are subjected to dynamic and static loads during rolling and are affected by wear and temperature changes, so that the rolls become important consumable parts for determining the efficiency of the rolling mill and the quality of rolled materials. In the prior art, the roller needs to be chamfered periodically after being used for a period of time in order to avoid end stress concentration, and the roller needs to be chamfered 3-5 times in the whole service period. As shown in fig. 1 and 2, a general operation flow is that, because the roll is installed on the chock during operation, and because the existing heavy-duty roll lathe only has a single-side tool block and the tool block base support has a large amount, if the chock is brought during chamfering operation, interference occurs (fig. 2), so that the chock at both ends of the roll needs to be removed first, and then the roll needs to be fixed on the lathe for chamfering. The bearing seat assembling and disassembling device has the disadvantages that the bearing seat disassembling and assembling work consumes a large amount of labor and working hours, the disassembling and assembling work intensity is high, and the economical efficiency is poor.

Therefore, how to design a device capable of chamfering a roller without dismantling a chock is a technical problem which needs to be solved urgently by the technical personnel in the field.
