Universal tool for stabilizing treatment of belleville spring

Abstract

The invention provides a universal tool for stabilizing treatment of a belleville spring, and belongs to the technical field of metal heat treatment.The universal tool comprises a base, a guide mandrel, a spacer ring and a pressing ring, the base, the guide mandrel, the spacer ring and the pressing ring are coaxially arranged from bottom to top, and one end of the guide mandrel is connected with the base in an embedded mode; the guiding mandrel is used for loading the belleville springs, the multiple belleville springs are loaded on the guiding mandrel in a back-to-back series connection mode, and the guiding diameter of the guiding mandrel is matched with the diameter of inner holes of the belleville springs. The inner hole diameter of the spacer ring is larger than the guide diameter of the guide mandrel. By the adoption of the universal tool for stabilizing the belleville springs, the tool can be shared by the belleville springs with the adjacent sizes; the number of the belleville springs subjected to stabilizing treatment can be adjusted according to the number of the spacer rings; meanwhile, for the belleville springs with large size difference, the stabilizing treatment of the belleville springs can be carried out only by replacing the guide mandrel and the spacer ring, the universality of the tool is good, and the tool is used for stabilizing the belleville springs.

Description

technical field [0001] The application belongs to the technical field of metal heat treatment, and in particular relates to a general tool for disc spring stabilization treatment. Background technique [0002] Disc springs are often used for strong buffering and vibration reduction under high load conditions. They have high stiffness and can bear large loads with small elastic deformation. They are a special spring. Due to the limitation of service tooling, a small number of disc springs need to have stable elastic force values ​​and be able to be precisely adjusted. After quenching and tempering, these disc springs need to be stabilized (forced) in accordance with the requirements of GB / T1972-2005 to correct the disc shape. The structural "pseudo-elastic" behavior of the spring due to the warping of the end face results in inconsistencies in the elastic compression stroke under the same load. [0003] In the related technology, the stabilization treatment of the disc sprin...
