Multifunctional same-furnace multi-band bimetal strip saw blade heat treatment full-automatic production line and process thereof

Abstract

The invention discloses a multifunctional same-furnace multi-band bimetal strip saw blade heat treatment full-automatic production line and a process thereof, relating to a bimetal strip saw blade production line and a compound quenching process and solving the problems of difficult control of equipment and process parameters, difficult guarantee of product quality, incapability of producing multiple saw blades in various specifications at the same time, low equipment capacity efficiency, high production cost and energy wastes of water, power and gas at present. In the invention, equipment inall working procedures are integrated into one production line, all the working procedures of quenching, tempering, sand blasting, cleaning, baking, marking, oil coating, straightening and the like are completed on the same production line, the production of multiple saw blades in various specifications can be completed at the same time, and after the invention is applied, the total capacity can be improved by 5-8 times, the service life of the product can be improved by around 50%, and the production cost can be reduced by more than 40%. An on-ling dynamic rapid-tempering novel technology isadopted for tempering equipment and process, thus the saw blades travels faster on the production line to complete the whole process of tempering so that high capacity can be achieved for the saw blades.

Description

technical field

[0001] The invention relates to a heat treatment production line for producing bimetallic band saw blade products and a process thereof. Background technique

[0002] The production process of bimetallic band saw blades (hereinafter referred to as saw blades) mainly includes composite steel strip welding, milling, grinding, splitting, heat treatment, sandblasting, cleaning, drying, marking, oiling, straightening, and alignment of finished saw blades. welding etc. At present, there are main problems: first, the equipment and process parameters are difficult to control, and the product quality is difficult to guarantee. For example, the uneven quenching and cooling temperature causes deformation of the saw blade. The gas purity in the bell tempering furnace is out of control, causing the saw blade to oxidize. The temperature in the furnace is uneven, resulting in uneven hardness of the saw blade. Uneven rewinding tension, causing the saw blade to warp, etc....
