Petroleum sucker rod quenching and tempering production line

The sucker rod quenching and tempering production line adopts an intermediate frequency induction hardening device, an intermediate frequency induction rod body tempering device, and a rod head induction tempering device. Its characteristics are: the quenching temperature and hardness of the head and the rod body are basically the same, the quenching speed is fast, the heating temperature is uniform, and the quenching, tempering and straightening can be completed at one time. The whole forehearth adopts stepless speed control, which is easy to operate.

The complete production line is mainly composed of mechanical conveying device, intermediate frequency quenching heating equipment, intermediate frequency tempering heating equipment, end tempering heating equipment, closed cooling system, infrared temperature measuring device, quenching cooling device, master console, etc. The mechanical conveying device includes a storage platform, a turning rack, a rail feeding device, and a discharge rack. The conveying method adopts inclined shaft rollers, and each roller is equipped with a step frequency conversion motor. It can ensure that the workpiece moves linearly during the heating process on the one hand, and rotates on the other hand, and the speed is automatically adjusted to ensure uniform temperature and reduce deformation, which has a certain straightening effect.

For the quenching spray part, we specially designed a self-cleaning filter to ensure the purity of the water in response to the clogging of the sprayer due to the impurities in the quenching water.
