Specifically, for rolled steel products, automatic feeding is achieved through a feeding mechanism, and the feeding mechanism conveys the steel products to the quenching heating furnace 2-3 so as to carry out quenching treatment on the steel products through the quenching heating furnace 2-3. After the steel is quenched, the steel is clamped by a third robot 2-5 and is conveyed to a guide arm forming machine 2-6 for forming so as to press the steel into the designed structural shape of the guide arm; then, the formed guide arm is placed into a quenching oil tank 2-7 for treatment through a third robot 2-5, the quenching oil tank 2-7 conveys the guide arm to move in oil and output, and the guide arm output from the quenching oil tank 2-7 is conveyed into a tempering furnace 2-9 through a fourth robot 2-8 for tempering treatment.

Wherein, as for the feeding mechanism, the feeding mechanism comprises a first feeding assembly 2-11 and a second feeding assembly 2-12, and the first feeding assembly 2-11 and the second feeding assembly 2-12 are respectively positioned at two sides of the stokehole feeding mechanism 2-2.

Thus, the heat loss amount of the steel material in the conveying process is reduced, so that the temperature of the steel material is always kept high, the time for heating the steel material through the second heating furnaces 1-22 is reduced, and the processing energy consumption is reduced.

And after the steel material is heated to the set temperature in the second heating furnace 1-22, the steel material is taken out from the second heating furnace 1-22 by the second robot 1-72 and is transferred to the one-side coil winding machine 1-5 for coil winding operation.
