Bell-type furnace capable of being used for local heating

Abstract

The invention provides a bell-type furnace capable of being used for local heating. The upper face of a furnace body and the lower face of the furnace body are respectively provided with a spring, a copper bar provided with silicon carbide rods is arranged in the furnace body, the silicon carbide rods are connected with the copper bar through conductive strips, a handle is installed on the side face, facing outwards, of the copper bar, the portions, at the two sides of the handle, of the copper bar are further provided with two hangers, the handle penetrates through the furnace body, and a sealing clamping groove capable of enabling the handle to slide is formed in the furnace body. Due to the fact that the handle is arranged on the copper bar, the position of the copper bar can be shifted through the handle. Therefore, motion of a heating element is achieved, after movement, the furnace body is sealed through the springs and a clamping device of the sealing groove, when an article needs to be sintered for multiple times, the trouble that the article needs to be taken out and placed in repeatedly is avoided, and the requirement for industrial mass production is satisfied.

Description

technical field [0001] The invention relates to the field of manufacturing equipment in the mechanical processing industry, in particular to the design and manufacture of a partially heated bell furnace. Background technique [0002] Industrial furnace occupies an extremely important position in the heat treatment process of machinery manufacturing industry. It is an essential key equipment to ensure product quality, improve machine working efficiency and prolong machine service life. With the rapid development of machinery manufacturing and equipment manufacturing, the demand for industrial furnaces is increasing year by year, so the improvement of industrial furnaces has become a very important and particularly prominent issue. The general bell furnace is mainly suitable for the high-temperature sintering process of magnetic materials, powder metallurgy, and electronic ceramics. There is a furnace inside the furnace, and there are heating elements in the furnace. Generally...

AI Technical Summary

Problems solved by technology

The general bell furnace is mainly suitable for the high temperature sintering process of magnetic materials, powder metallurgy and electronic ceramics. There is a furnace in the furnace body, and a heating element is installed in the furnace. Generally, there are two types of heating elements. If the temperature is normal, a resistance band is used. If the required temperature is higher, silicon carbide rods are used. The heating elements of traditional bell furnaces are all fixed heating elements. The items where the components are located are sintered, but if one item or different items need to be sintered at different parts at high temperature, the items need to be taken out and placed again. The procedures are cumbersome, which is not conducive to the requirements of industrialized mass production.
