Description

TECHNICAL FIELD

[0001] The utility model relates to spiral retaining ring production technical field, concretely for small batch spiral retaining ring high -efficient forming mechanism. BACKGROUND

[0002] Spiral retaining ring (Spiral Retaining Ring), also called spiral elastic retaining ring, shape as shown in the figure, is made of flat wire, has good elasticity and toughness after heat treatment and surface treatment. Figure 3 It is divided into shaft and hole, single ring, double ring and multiple ring according to different loads, and is used for axial positioning, and because it does not have lugs, it is generally used in space limited occasions. In the existing spiral retaining ring forming process, winding is a key process, and the general method is to send the flat wire into the numerical control winding machine for winding. Two main parameters need to be controlled during winding, one is the pitch, and the other is the outer diameter. The pitch is too small, and the winding is not opened. If the pitch is too large, the two surfaces of the wound part are not fitted. Generally, the pitch is one time of the material thickness for trial winding, and adjustment is made according to the trial winding. If the two surfaces are not fitted, the pitch is appropriately reduced. The outer diameter is adjusted according to the numerical control machine tool parameters, and the winding is also carefully adjusted. After winding, the part is cut off according to the length of the part. After winding, the layers should be tightly fitted, and the interlayer gap is not greater than 0.1 in the free state. Because the number of spiral retaining ring orders undertaken by our company is small, the numerical control winding machine greatly increases the production cost. Therefore, we design a manual forming mechanism to meet the production demand. UTILITARIAN CONTENT
