[0003] When the spring stiffness is fixed, the current maximum working range of the spring is that the spring works until the coils are in contact. Since the coils have been tightened, the spring loses its elastic characteristics and cannot continue to play the role of the spring. How can a spring increase the spring? The working stroke increases the load of the spring to meet the higher load requirements of the assembly, especially under the premise that the spring installation space is limited and the spring working stroke is limited. How can the same spring increase the working stroke and obtain a wider range of use? , is the problem that our spring manufacturers need to solve

Abstract
The invention discloses a manufacturing process of a spiral compression eccentric spring and a spring product thereof, and belongs to the technical field of spring manufacturing processes. The manufacturing process comprises the following steps: spring winding: spring winding programs are established through calculation of the outer diameter size differences of near rings of springs; and the springs with staggered sizes of the near rings are manufactured through computer control molding; and spring tempering: according to requested solid heights of the springs, the springs are molded through mastering the outer diameter size deformations of the springs by calculation; the size deformation rules after heat treatment of spring materials are mastered; corresponding tempering temperatures andtempering time are set for the wound springs; and the springs are naturally tempered to form eccentric springs with ordered and staggered outer diameter sizes. Under the preconditions of not changingtraditional designed material wire diameters, outer diameter and circle numbers, the solid heights of the spring products can be effectively reduced, and the working travels and the loads are increased.
Description
technical field [0001] The invention relates to a manufacturing process of a helically compressed eccentric spring and a spring product thereof, belonging to the technical field of spring manufacturing technology. Background technique [0002] The development of springs has a history of more than 200 years. According to the different use environments and requirements of various springs, the shapes of springs are also different. At present, the introduction of springs in various standards, documents, and materials is also cylindrical, truncated cone, drum-shaped springs, etc. During the use of springs, what customers pay most attention to is the spring performance-load, and the spring load is closely related to the spring stiffness. Inseparable relationship, that is, spring load = spring stiffness * spring working stroke. [0003] When the spring stiffness is fixed, the current maximum working range of the spring is that the spring works until the coils are in contact. Since...
