Problems solved by technology

[0003] like figure 1 As shown in the prior art, after sorting the disassembled roll 3 and the bearing seat, the grinding wheel 8 is used to grind the rotary roll 3 alone. However, some rolling mills have high rolling precision, and the roll and the bearing are closely matched. The separation operation is difficult to complete, and sometimes special equipment is required for separation and assembly operations. At the same time, the process of separation and reassembly may affect the assembly accuracy, reduce the accuracy of the rolling mill, and the separation and reassembly of rolls and bearing housings consumes manpower and time, increasing production costs and reducing productivity

Embodiment Construction

[0029] Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail:

[0030] like figure 1 The shown schematic diagram of the prior art roll grinding process has been described in detail in the background art, and will not be repeated here.

[0031] like Figure 2 to Figure 8 As described, the present embodiment provides a method for rapid grinding of small rolling mill rolls, comprising the following steps:

[0032] 1) After the roll 3 is pulled out from the rolling mill, the blind cover of the bearing seat 4 is removed to expose the top hole of the roll 3;

[0033] 2) First process a threaded hole on the top surface of each bearing seat 4, and then fix the lifting ring 9 on the top surface of the bearing seat 4 through the bolts matched with the threaded hole, for hoisting the roll 3 and bearing seat 4;

[0034] 3) Hang the roll 3 and the bearing housing 4 together on the roll grinder, the headstock 1 a...

Abstract

The invention discloses a rapid abrasive machining method for a small mill roller. According to the method, separate operation of the roller and a bearing seat is not needed, the roller and the bearing seat are together suspended directly onto a grinding machine, dedicated cushion blocks are designed to support and position the bearing seat, and the roller is driven to rotate through a driving device of the grinding machine so that abrasive machining of the roller can be achieved. The rapid abrasive machining method for the small mill roller is rapid, efficient, safe, simple and convenient, operation processes are reduced, the labor intensity is decreased, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of rolling mill roll grinding, in particular to a small-sized rolling mill roll rapid grinding process method. Background technique [0002] Since the roll surface of the rolling mill will be worn during the rolling process, in order to ensure the surface quality of the steel plate, it is required to grind the roll surface frequently. [0003] like figure 1 As shown in the prior art, after sorting the disassembled roll 3 and the bearing seat, the grinding wheel 8 is used to grind the rotary roll 3 alone. However, some rolling mills have high rolling precision, and the roll and the bearing are closely matched. The separation operation is difficult to complete, and sometimes special equipment is required for separation and assembly operations. At the same time, the process of separation and reassembly may affect the assembly accuracy, reduce the accuracy of the rolling mill, and the separation and reassembly ...
