Piston rings are very common components and are used in many fields. In the production process of piston rings, the piston rings after rough machining need to be subjected to treatments such as quenching and tempering, the piston rings are small in volume, and the single treatment is very labor-intensive and material-intensive, so that the piston rings are often bundled together during machining. When the piston rings are bundled, the piston rings are required to be stacked orderly, and a waste piston ring or a ring-shaped rigid body is placed at each of two ends of the piston rings, so that the piston rings are prevented from being damaged when the piston rings are bundled; the piston rings were then tied up with iron wire and the tied up piston rings were as shown in fig. 1. After the whole stack of piston rings are quenched, the iron wires can deform to a certain extent, so that the tied piston rings are not tidy any more, the piston rings can be skewed and twisted, and the piston rings are difficult to put into a tempering barrel for next tempering treatment under the condition. At present, the conventional method is that the piston ring is restored to be tidy and then is stacked in the tempering barrel in a manual knocking mode, and the method has many defects: firstly, manual operation is needed, time and labor are wasted, and the cost is high; secondly, the stacking quality cannot be ensured, so that the subsequent tempering quality can be influenced; thirdly, when knocking, the piston ring is easily damaged, and the rate of finished products is greatly influenced.
