Description

Technical Field

[0001] The utility model relates to the technical field of disc spring processing, in particular to a feeding device for disc spring heat treatment. Background Art

[0002] Disc springs (disc springs), also known as Belleville spring washers, are conical discs that can be used individually or in series or in parallel. They bear static or dynamic loads acting in the axial direction at the upper inner edge and the lower outer edge. After being compressed, they deform until they are flattened, storing energy as a live load. When necessary, it is automatically converted into the additional compressive load required for sealing to reduce the continuous tightening requirements of gaskets and packings during use. In the conventional production process of disc springs, heat treatment processes are often required. The disc springs have better performance through quenching. During the quenching process of the disc spring, the workpiece is heated to 880-920℃ in a medium frequency heating device and placed in a press quenching mold. The hydraulic press presses down the upper die to form the disc spring blank. At the same time, the forming time is controlled. After about 2.8-3s (temperature is about 850℃), a signal is sent to activate the solenoid valve, and quenching oil is sprayed into the die cavity to start quenching, thereby completing the heat treatment of the disc spring. During the heat treatment of the disc spring, the disc spring needs to be loaded through a loading device. When loading, the disc springs are placed in a scattered manner in the collection frame. When placed and transported, the disc springs need to be stacked one by one in the corresponding conveying channel, which makes the disc spring loading not intelligent enough and reduces the loading efficiency of the disc spring. For this reason, we propose a loading device for disc spring heat treatment. Utility Model Content
