Description

TECHNICAL FIELD

[0001] The present application relates to the field of heating equipment, in particular to a multi-station saw blade heat treatment device with uniform heating on both sides. BACKGROUND

[0002] Currently, saw blade heat treatment is divided into vertical and horizontal types according to the placement position of the saw blade. Regardless of the type, the process steps mainly include heating, quenching, flattening, cleaning, etc. The heating and quenching steps are the key steps of saw blade heat treatment, that is, the key to the treatment effect and efficiency. In the prior art, regardless of vertical or horizontal type, the heating and quenching are specifically operated by feeding the saw blade into the heating furnace for heating, and then feeding the saw blade out of the heating furnace and directly into the quenching mechanism (quenching tank or quenching press) for quenching. The saw blade can start heat treatment after being directly fed into the heating furnace.

While the furnace body and the electric radiation tube rotate around the saw blade, the saw blade performs self-rotation, thereby effectively enhancing the sufficient heat treatment of the saw blade and further enhancing the uniformity of the saw blade heating. However, the above-mentioned solution has the problem that the two sides of the saw blade are always fixed, one side in contact with the support seat is covered, which can cause temperature inconsistency between the two sides of the saw blade during quenching, thereby causing deformation of the saw blade and affecting the treatment effect of the saw blade.
