[0002] After oil quenching, fasteners can obtain good comprehensive mechanical properties, including improved hardness, strength and wear resistance, and can also reduce the risk of deformation and cracks to a certain extent. The oil is relatively more stable during the quenching process and is not easy to cause oxidation and decarburization on the surface of the workpiece, which is conducive to maintaining the long-term performance of the fasteners. The Chinese patent with publication number CN220335243U discloses a fastener quenching device, including a cooling box, a bracket, a fastener access tube, a motor, a hexagonal rotating shaft, a bearing and a support rod.

The upper part of the cooling box is fixedly connected to two support rods, and the two support rods are symmetrically arranged. The device can better complete the quenching of the fasteners in the cooling box, but the subsequent work requires the removal of the slot plate to remove the fasteners therefrom, and then the subsequent cleaning of the coolant, and the production efficiency needs to be improved.
