Boiler economizer manufacturing and forming machining machine and forming machining method

Abstract

The invention relates to a boiler economizer manufacturing and forming machining machine and a forming machining method. The boiler economizer manufacturing and forming machining machine comprises a base, a fixing device and chamfering devices, the lower end of the base is connected with the existing ground, the fixing device is installed at the upper end of the base, and the chamfering devices are symmetrically arranged on the front side and the rear side of the fixing device. Through mutual cooperation of a bearing frame, an annular gear, a clamping rod and a hoop, a steel pipe of a boiler economizer can be fixed to prevent the steel pipe from shaking, and meanwhile, a bearing table is arranged to play a role in bearing the steel pipe of the boiler economizer, the machining process is more stable, and through cooperation of the hoop and the clamping rod, the hoop can be conveniently and rapidly disassembled and assembled by workers, the fixing speed is increased, the machining efficiency is improved, and meanwhile, the steel pipes can be chamfered in batches by arranging multiple annular gears and hoops, and then the machining forming efficiency of the boiler economizer can be improved.

Description

technical field [0001] The invention relates to the technical field of boiler economizers, in particular to a manufacturing molding processing machine and molding processing method for boiler economizers. Background technique [0002] The economizer is a device installed at the lower part of the boiler tail flue to recover the waste heat of the exhausted smoke. It heats the boiler feed water into a saturated water heating surface under the pressure of the steam drum. Because it absorbs the heat of the high-temperature flue gas, it reduces The exhaust temperature of the flue gas is improved, energy is saved, and efficiency is improved, so it is called an economizer. The economizer is divided into two types according to the manufacturing materials: there are two kinds of cast iron and steel pipe economizers, and non-boiling economizers are mostly used. It is made of cast iron, but it is also made of steel pipes, and the boiling economizer can only be made of steel pipes. Cast ...

AI Technical Summary

Problems solved by technology

[0003] 1. In the process of chamfering the steel pipe, the steel pipe is prone to shaking and shifting, and it is impossible to perform batch chamfering at one time, so that the chamfering rate of the steel pipe is lower;

[0004] 2. In the process of chamfering and aligning, the chamfering plate is easy to fall due to excessive impact force, and the equipment can only chamfer the steel pipe in one size, which makes the equipment less practical
