Serpentine spring forming tool for serpentine spring coupler

Abstract

The invention discloses a serpentine spring forming tool for a serpentine spring coupler. The serpentine spring forming tool comprises a base, a guide cylinder and a bending structure, wherein the guide cylinder is fixedly arranged on the base; the bending structure is arranged on the guide cylinder; the guide cylinder is provided with symmetrically arranged positioning holes; the bending structure comprises bolts and a bending wrench; the bolts are embedded in the positioning holes; and the bending wrench is also embedded in one positioning hole and rotatably arranged in the positioning hole.According to the serpentine spring forming tool for the serpentine spring coupler, the position relation between the bolts can be better controlled through the positioning holes, so that it is ensured that the assembly clearances are consistent, and the load of a manufactured serpentine spring is balanced; and through the bending structure, it can be ensured that the formed two ends of the springare symmetrical, the circumferential array is uniform, the transition fillet can be smooth, and the stress concentration cannot occur.

Description

technical field [0001] The invention relates to the field of spring processing, in particular to a serpentine spring forming tool for a serpentine spring coupling. Background technique [0002] The two tooth surfaces of the serpentine spring coupling are composed of multiple arc surfaces, which are connected through the lining of the serpentine spring, so that they can withstand load impact and changing load more. Since the cross section of the serpentine spring is a rectangular conical surface structure, the structural characteristics of the serpentine spring product, such as asymmetrical spring forming at both ends, uneven circumferential array, and uneven transition R angle, will lead to concentrated stress on the load and inconsistent assembly clearance. , the load is unbalanced, and the risk of fracture is prone to occur, which affects the assembly quality and performance. It is an urgent task to study a forming snake spring manufacturing process to solve the impact cau...

Since the cross section of the serpentine spring is a rectangular conical surface structure, the structural characteristics of the serpentine spring product, such as asymmetrical spring forming at both ends, uneven circumferential array, and uneven transition R angle, will lead to concentrated stress on the load and inconsistent assembly clearance. , the load is unbalanced, and the risk of fracture is very prone to occur, which affects the assembly quality and performance. It is an urgent task to study a forming serpentine spring manufacturing process to solve the impact caused by assembly and use characteristics.
