Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment equipment, in particular to heat treatment equipment for processing nonferrous metal materials. Background Art

[0002] Heat treatment is one of the important processes in mechanical manufacturing. Compared with other processing technologies, heat treatment generally does not change the shape and overall chemical composition of the workpiece, but rather imparts or improves the performance of the workpiece by changing the microstructure inside the workpiece or changing the chemical composition of the workpiece surface.

[0003] In the processing of non-ferrous metal workpieces, heat treatment is a necessary step. When doing annealing, tempering and other processes, a mesh belt furnace is usually used. The non-ferrous metal workpiece is laid flat on the conveyor mesh belt of the mesh belt furnace. The mesh belt sends the workpiece into the heating zone, heats the workpiece to an appropriate temperature and keeps it warm for a period of time, and then cools it down through cold air equipment. There are some functional deficiencies in actual use and there is room for improvement. For example, the non-ferrous metal workpieces that have undergone preliminary treatment are delivered to the conveyor mesh belt by the feeding mechanism, and the fallen metal workpieces have a certain probability of stacking, which needs to be turned over manually to avoid uneven local heating of the corresponding workpieces caused by stacking. Since the temperature of the conveyor mesh belt itself is high, manual operation is difficult and burns are prone to occur. There is no function of conveying height limit to prevent workpiece stacking.

[0004] Now, a new type of heat treatment equipment for processing nonferrous metal materials is proposed to solve the above problems. Utility Model Content
