Description

Technical Field

[0001] The utility model specifically relates to the technical field of uniform quenching and cooling, in particular to a continuous heat treatment device with uniform quenching and cooling. Background Art

[0002] Quenching and cooling technology refers to the technology of cooling metal materials and components in a predetermined manner and rate after they are heated to a certain temperature to obtain the expected structure and performance, including quenching process and process optimization, quenching medium and its performance evaluation, quenching equipment, cooling process and its parameter control, cooling process simulation and performance prediction, quenching distortion, cracking and residual stress control. Quenching and cooling is a basic process of heat treatment.

[0003] At present, when traditional plates or rods are quenched and cooled, cooling oil is usually used to cool the workpiece. When the workpiece enters the cooling oil, there is a time difference in the time when the workpiece enters. This may cause the internal structure of the workpiece to change during quenching, and even cause surface cracks in severe cases. This cannot effectively guarantee the quality of the workpiece and affects the service life of the workpiece in later use.

[0004] After searching, Chinese patent publication number CN201920567315.2 discloses a quenching cooling device for bearing roller parts; comprising: a cooling water tank; an induction coil, the induction coil is located above the cooling water tank; a cooling device, the cooling device is arranged in the cooling water tank and is connected to the cooling water tank, the top of the cooling device passes through the cooling water tank and is located below the induction coil, and the cooling device is connected to a water replenishing device; a chain conveyor, the chain conveyor is arranged in the cooling water tank;

[0005] When cooling the workpiece, the structure in the above patent transfers the workpiece heated by the induction coil to the cooling device, and a water replenishing device is connected to the cooling device. Since the workpiece needs to be transferred to the chain conveyor through the inner tube body, the inner tube body and the cooling water tank need to be connected. In this way, when replenishing water, the water replenishing device cannot effectively replenish the cooling water inside the inner tube body to a level higher than the cooling water inside the cooling water tank. In this way, when cooling, the structure in the above patent cannot effectively achieve the effect of cooling the workpiece in advance. When the device in the above patent cools the parts, there will still be time difference.

[0006] In view of the above situation, we provide a continuous heat treatment device with uniform quenching and cooling. In this device, an upper mounting shell and a lower mounting shell are symmetrically installed in the upper and lower directions inside the shell. Cooling nozzles are installed on the upper mounting shell and the lower mounting shell. The cooling nozzles are connected to the screw rod through the mounting block. The movement of the cooling nozzles can be effectively realized by driving the driving motor. In this way, when cooling the workpiece, both sides of the sheet can be uniformly cooled at the same time, which greatly improves the cooling efficiency. Utility Model Content
