Abstract

The invention discloses a corrugated spring forming blank, a corrugated spring forming mold and a corrugated spring processing method. The corrugated spring forming blank comprises a to-be-stamped corrugated spring blank body that has been formed and is about to stamp a corrugated spring, and a connecting part connected into an entirety with the to-be-stamped corrugated spring blank body, and a wavy conical surface is arranged on the connecting part, and the wavy conical surface is connected with the to-be-stamped corrugated spring blank body, is formed when a to-be-formed part is stretched into the to-be-stamped corrugated spring blank body, has a set stretching height and is in natural transition. By the adoption of the corrugated spring forming blank, the corrugated spring forming mold and the corrugated spring processing method disclosed by the invention, the precision processing problem of a non-aging reinforced material corrugated spring with higher hardness requirements and smaller diameter is solved; the applicability is wide, and the precision forming of corrugated springs made of all kinds of materials can be applicable; and the processing precision and efficiency are high, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the field of spring processing, in particular to a corrugated spring forming blank, forming mold and processing method. Background technique [0002] For the forming process of the corrugated spring, the method of punching + bending forming or punching + stretching is currently used, which can meet the forming needs of most corrugated springs. However, for corrugated springs of non-aging reinforced materials with high hardness indicators, a high tensile height is required, the diameter of the required blank material will be much larger than the outer diameter of the part, and the material utilization rate is low; in the semi-hard state and above When the material is formed, the corrugated spring with a small diameter is easy to be stretched and broken, and the corrugated shape is difficult to form; it is difficult to achieve the hardness and elasticity requirements through aging when stretching the annealed or low-hardness mate...
