Problems solved by technology

[0002] Heat treatment refers to a processing technology in which the material is heated, kept warm and cooled in a solid state to obtain the desired structure and performance; the existing workpiece heat treatment process mainly consists of workers placing the workpiece in a heating device and heating it to a specified temperature. , and then placed in the heat preservation device for heat preservation. When the heat preservation time is reached, the worker puts the workpiece into the cooling device for cooling. The heat treatment of the workpiece is done manually, which greatly improves the cost of employment, and Increase the probability of industrial accidents; at the same time, because the workpiece is in contact with the outside air several times during the heat treatment process, it will greatly affect the effect of the heat treatment of the workpiece

Abstract

The invention discloses a tunnel furnace and a workpiece thermal treatment process. The tunnel furnace comprises a feeding portion for receiving a workpiece, a preheating portion connected with the feeding portion and used for preheating the workpiece, a constant-temperature portion connected with the preheating portion and used for heating the workpiece at the constant temperature, a heat insulation portion connected with the constant temperature portion and used for keeping the temperature of the workpiece, a shock cooling portion connected with a transition portion and used for quickly cooling the workpiece, a cooling portion connected with the shock cooling portion and used for continuously cooling the workpiece and a discharging portion connected with the cooling portion and used for receiving the workpiece. The tunnel furnace and the workpiece thermal treatment process have the beneficial effects that the automatic level of the workpiece thermal treatment and the workpiece thermal treatment effect are improved, the labor is reduced, and accordingly the production cost of enterprises and the occupational injury rate generated in the production process are lowered; and meanwhile, the situation that the workpiece is in contact with the external air in the thermal treatment process is avoided by means of the tunnel furnace, so that the thermal treatment effect of the workpiece is guaranteed greatly, the heating uniformity and the heating effect of the workpiece are improved, and the cooling and shaping effect of the workpiece is improved.
