Abstract

The invention discloses a full-automatic production line for synchronous furnace multi-band bright quenching of bimetal band saw blades and relates to the full-automatic production line for quenchingthe metal band saw blades. The full-automatic production line can solve the problem that the prior quenching device of the bimetal band saw blades can not realize the synchronous furnace multi-band quenching technology, thereby causing low production efficiency of the quenching technology of the metal band saw blades and waste of a large amount of energy. N heating units are arranged in a casing,a thermal insulating layer is arranged between the N heating units and the casing, and a plurality of silicon-molybdenum bar heating elements sequentially penetrate the casing and the thermal insulating layer and evenly distributed and arranged between each two heating units and between the thermal insulating layer and the heating units; and a channel of the metal band saw blades is formed in themiddle part of a main body of a chiller, and a plurality of side channels for arranging refrigerant flow channels are respectively arranged on two sides of the channel of the metal band saw blades. The full-automatic production line can realize the bright continuous quenching of a plurality of bimetal band saw blades and monometal band saw blades in the same quenching production line. The full-automatic production line has the advantages of high productivity, low comprehensive energy consumption, reasonable device structure and the like.

Description

technical field [0001] The invention relates to a fully automatic production line for quenching metal band saw blades. Background technique [0002] The bimetallic band saw blade is made of high-cobalt high-speed steel on the tooth part and alloy spring steel on the back to form a semi-finished blank by vacuum electron beam welding, and is processed by milling, dividing, heat treatment, surface treatment and other processes. At present, the bimetallic band saw blade quenching device used in the same industry at home and abroad can only realize the quenching process of a single saw blade (single band in the same furnace), and cannot realize the multi-band quenching process of the bimetallic band saw blade in the same furnace. In other words, the prior art does not provide process equipment capable of quenching multiple bimetal band saw blades at the same time, resulting in low production efficiency of the quenching process for metal band saw blades and wasting a lot of energy...
