Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] The furnace roller system used in the roller hearth heating furnace is roughly composed of furnace rollers, roller conveyor motors (with reducers), furnace roller bearing housings, couplings, water-cooled furnace roller rotary joints and other components. According to the installation reference line and the appearance size of the furnace roller bearing seat, adjust the furnace roller bearing seat in place, fix the base after leveling; and then carry out the furnace roller seat. According to the length of the furnace and the number of rollers in the furnace, the installation reference roller table should be reasonably determined. Generally, three groups of roller tables at the inlet and outlet end and the middle position are selected as the reference rollers for installation (refer to the attached figure 1 ). Adjust the accuracy of ot...

Abstract

The invention discloses a conveying roller mounting precision control method of a roller bottom heat treatment furnace. The method comprises the steps of roller way assembly, lifting, finish adjustment of a standard roller way, finish adjustment of a nonstandard roller way, installation of a roller way driving device and overall adjustment of the roller ways. The method reasonably sets a standard roller, divides different mounting working surfaces, adjusts the precision of working rollers mounted on the working surfaces with all mounting control precision indexes of the standard roller way as basis, improves the mounting efficiency, accelerates the mounting speed, guarantees the mounting quality, is clear in mounting sequence, is precise in positioning, and prevents the problems of rework and work delaying. The method reasonably uses such auxiliary mounting tools as 5 m steel flat rulers, can realize overall adjustment of one set of several roller ways, accelerates the mounting progress, and meanwhile, can adopt a superposition progressive mode to guarantee non-overproof mounting errors.

Description

technical field [0001] The invention relates to the field of installation of heating furnace mechanical equipment, in particular to a method for controlling the installation accuracy of conveying rollers in a profile roller hearth type heat treatment furnace. Background technique [0002] The roller table in the furnace is the key moving part of the roller hearth heat treatment furnace. The roller table in the furnace bears the weight of the profile in the heat treatment process, and also determines the running track of the profile, and the vertical and horizontal deviation of the profile is determined by this. The installation accuracy of the roller table in the furnace is the fundamental guarantee for the motion accuracy of the heat treatment furnace, so the installation quality of the conveyor roller table in the heat treatment furnace is very important. Since the general profile heat treatment furnace has the characteristics of long effective length and large number of ...
