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.
