Take you to understand the internal gear induction quenching production line consisting of medium frequency induction quenching machine and high frequency induction quenching machine

In order to make the internal gear quenching effect better, we have developed an internal gear induction quenching production line consisting of a medium-frequency induction quenching machine, a high-frequency induction quenching machine and a CNC induction quenching machine tool. According to many people who have used it, the quenching effect of this production line is very good, and the quenched internal gears meet the needs of the work.

The gears in this production line are removed one piece at a time and are operated by two opposite cylinders. When the workpiece is in the loading position, a proximity switch acts, causing the pneumatic reciprocating rod to push the workpiece to the quenching station. This station has a variable speed servo drive and vertical scanning carriage. When the gear reaches the quenching station, another proximity switch is activated. Therefore, the vertical scanner drags the internal gear from the reciprocating rod and places the workpiece in the directional position under the sensor. There are two proximity switches used as special positioning instructions. If the position is wrong, the workpiece will return to the reciprocating rod for reloading.

Once misaligned, the machine tool stops running, and at the same time, a diagnostic display screen indicates that the workpiece is not in the quenching station. If the internal gear is positioned correctly and is accepted by the workpiece orientation station, the scanning mechanism will feed it into the sensor. Once the inductor is in the internal gear, the medium frequency induction annealing machine starts heating, the workpiece rotates, and at the same time the scanning mechanism lowers the workpiece, allowing the inductor to scan and preheat the entire length of the internal gear.

After the intermediate frequency preheating is completed, the scanning positioner rises and returns to its original position. The power conversion switch is transferred to the high-frequency power supply. The workpiece rotates and descends again. The preheated gear is scanned and quenched by a high-frequency annealing machine. After the quenched internal gear is lowered to the reciprocating rod, the reciprocating rod pushes the workpiece to the tempering station, and its positioning signal action is the same as that of the quenching station. Tempering is a one-time heating method, and the workpiece is rotating during tempering. The tempering power is small and is carried out during the interval between high-frequency induction quenching of the gear.

After the tempering process is completed, the gear is lowered to the reciprocating rod, pushed to the cooling station, and cooled to the loading and unloading temperature by the spray head. Then the workpiece is sent to the vertebral sorting station (passed or rejected). Rejection is determined by a number of detection devices. If the internal gear is determined to be ejected, a pneumatic discharge rod mounted on the side will push the gear horizontally and slide it to the ejection discharge box. If the gear is qualified, it will be pushed to the discharge box.
