Abstract

The invention discloses an automatic production line for saw blade heat treatment, and belongs to the technical field of work piece heat treatment. The automatic production line for the saw blade heat treatment is characterized by comprising a feed mechanism, a feeding tray stepping advancing mechanism, a heat preserving furnace, a carbon-nitrogen furnace, a quenching mechanism, a cleaning machine, a tempering furnace and feeding tray conveying mechanisms, wherein the feed mechanism, the feeding tray stepping advancing mechanism, the heat preserving furnace, the carbon-nitrogen furnace, the quenching mechanism, the cleaning machine, the tempering furnace are sequentially arranged according to a manufacturing process order, and the feeding tray conveying mechanisms are arranged between each two adjacent devices. The feeding tray conveying mechanisms comprise a transition cylinder, a carbon-nitrogen furnace discharging advancing device, a quenching discharging advancing device, a tempering furnace feeding advancing device and a tempering furnace discharging advancing device, wherein the transition cylinder is arranged between the heat preserving furnace and the carbon-nitrogen furnace, the carbon-nitrogen furnace discharging advancing device is arranged on one side of the carbon-nitrogen furnace, the quenching discharging advancing device is arranged between the quenching mechanism and the cleaning machine, the tempering furnace feeding advancing device is arranged between the cleaning machine and the tempering furnace, and the tempering furnace discharging advancing device is arranged at an outlet of the tempering furnace. The automatic production line for the saw blade heat treatment has the advantages of improving production efficiency and energy use rates of the devices, ensuring heat treatment quality of saw blades due to continuous production, achieving automation operation of the whole production line and being small in number of employed workers and good in labor environment.

Description

technical field [0001] The invention relates to saw blade heat treatment equipment, in particular to an automatic production line for saw blade heat treatment. Background technique [0002] Saw blade is an indispensable cutting material in mechanical processing. Its quality is closely related to the heat treatment process of the saw blade. For example, the hardness, strength, toughness and wear resistance of the saw blade basically depend on the surface quenching and tempering treatment effect of the saw blade. At present, the heat treatment of hand-used hacksaw blades in the saw blade industry basically adopts the old technology, old technology, and discontinuous production methods in the past. For example, the quenching process generally adopts the well-type salt bath quenching heating method. The use of coal heating not only causes serious pollution, but also fails to meet environmental protection standards. Energy is wasted, production costs are high, and product qua...
