Quick hook lifting device and method for tension spring

Abstract

The invention belongs to the technical field of elastic element manufacturing, and relates to a quick tension spring hooking device and method. The device comprises a base table board and a rotating body, a through groove matched with the rotating body is formed in the table top of the base body. The upper end face of the rotating body is flush with the table face of the base body. An extrusion block with a semicircular groove is arranged on the upper end surface of the rotating body; a first boss and a second boss are arranged along the tangent positions, perpendicular to each other, of the upper end face of the rotating body, the first boss serves as a placing table top of a spring to be machined, and the second boss serves as a limiting structure of the spring to be machined. By means of the device, quick hooking of the tension spring is achieved, the problems of low spring shackle production efficiency and unstable quality caused by an original shackle hooking mode are solved, secondary rework is avoided, and the forming quality stability of the shackle and the production efficiency of parts are improved.

Description

technical field [0001] The invention belongs to the technical field of elastic element manufacturing, and relates to a device and method for quick hooking of an extension spring. Background technique [0002] The tension spring is a spring that mainly bears axial tension during work. The tension spring is mainly composed of a coil and an end hook ring. The processing step of the tension spring is to first wind the steel wire along the mandrel on the lathe by the lathe. into a spiral shape, and then the spring fitter uses pliers and other tools to bend the end into a hook-and-loop shape. Due to the lack of other mechanical equipment for the hook-and-loop bending work, it is completely manual operation, the production efficiency is very low, and it is affected by the individual skills of the operator. The influence of the level is relatively large, and the forming quality of the shackle is uneven, which seriously restricts the high-quality development of spring manufacturing. ...
