Punching calibration device for outer wall of furnace shell of intermediate frequency furnace

Abstract

The invention belongs to the technical field of power equipment, and particularly relates to a punching calibration device for the outer wall of a furnace shell of an intermediate frequency furnace, the punching calibration device comprises a horizontal bottom plate, supporting columns are uniformly and fixedly mounted on the upper surface of the bottom plate, and a horizontal machining table is jointly and fixedly mounted at the tops of the uniformly arranged supporting columns; a clamping mechanism and a punching mechanism are mounted on the bottom plate; when the outer wall of the furnace shell of the intermediate frequency furnace is punched through the punching device, it is guaranteed that the abrasion degrees of all the cutting blocks are consistent, and therefore material waste is reduced; and after trepanning is finished, the grinding wheel horizontally moves in the rotating state to calibrate the two side walls of the kidney-shaped hole, it is guaranteed that the two side walls of the kidney-shaped groove are flush, and it is further guaranteed that the shape of the kidney-shaped hole is regular.

Description

technical field [0001] The invention belongs to the technical field of electric power equipment, and in particular relates to a punching and calibrating device for the outer wall of an intermediate frequency furnace shell. Background technique [0002] The intermediate frequency furnace is a power supply device that converts the power frequency 50HZ alternating current into an intermediate frequency. The working frequency of the intermediate frequency furnace is between 50-2000Hz, and is widely used in the smelting of non-ferrous metals and ferrous metals. Compared with other casting equipment, the intermediate frequency furnace has the advantages of high thermal efficiency, short melting time, less burning loss of alloy elements, wide range of melting materials, less environmental pollution, and precise control of the temperature and composition of molten metal. The intermediate frequency furnace is composed of a furnace cover, a crucible, a reducer, an induction coil, a ta...

AI Technical Summary

Problems solved by technology

[0003] At present, there are the following problems when drilling the outer wall of the intermediate frequency furnace shell: (1) Since the furnace shell is an arc surface, when the existing annular cutting knife is used to punch the furnace shell, the force on the cutting knife is large. Different, after using for a period of time, the upper part of the cutting knife will be worn to a greater extent, and the rest of the position will be less worn. In this case, the cutting knife still needs to be replaced as a whole, resulting in waste of materials; (2) by cutting When the knife punches the furnace shell, the furnace shell is easily deformed by the impact force, resulting in irregular shape of the waist-shaped hole, which affects the molding quality of the furnace shell
