Expanded hood type saw blade sintering furnace

Abstract

The invention provides an expanded hood type saw blade sintering furnace comprising a base, a liner, a hood, a cover, a support and two guide posts. The base is disposed right in the center of the support. The guide posts are disposed on two sides of the support and are not equal in height. The short guide post has height, 40% of furnace height. The long guide post has height, 50% of the furnace height. Therefore, sleeves at two ends of the hood are allowed to sleeve the guide posts different in height conveniently during positioning; no high positioning standard is required for low- and medium-end products, and the products just need to be qualified. The expanded hood type saw blade sintering furnace has the advantages that the guide posts have smaller height, the requirement for material strength of the guide posts is low, positioning is efficient, and qualified products can be produced.

Description

technical field [0001] The invention belongs to the technical field of heat treatment processing equipment, and in particular relates to a rough bell-type saw blade sintering furnace. Background technique [0002] At present, the positioning device of the traditional bell-type furnace mainly includes guide columns of different lengths arranged at both ends of the bell-type furnace and matching sleeves on the furnace cover body. Therefore, generally speaking, the guide posts are relatively high, so that the positioning will be more accurate, but many manufacturers do not actually consider the grade of the product when designing. 30-50% of the furnace body is released. On the one hand, the material strength of the guide column is required to be high, which leads to an increase in cost. On the other hand, when there is a deviation between the driving hook and the center of gravity of the furnace cover, it is easy to get stuck, and the operation will often occur if the operation...

Therefore, generally speaking, the guide posts are relatively high, so that the positioning will be more accurate, but many manufacturers do not actually consider the grade of the product when designing. 30-50% of the furnace body is released. On the one hand, the material strength of the guide column is required to be high, which leads to an increase in cost. On the other hand, when there is a deviation between the driving hook and the center of gravity of the furnace cover, it is easy to get stuck, and the operation will often occur if the operation is slightly improper. The furnace cover hits the guide column, and the furnace cover or guide column is damaged
