Rectangular spring forming equipment

Abstract

The invention discloses rectangular spring forming equipment, and relates to the technical field of rectangular spring production equipment. The rectangular spring forming equipment comprises a frame body, a driving motor is installed on one side of the frame body, the output end of the driving motor is coaxially and fixedly connected with a driving shaft, the driving shaft is coaxially and fixedly connected with a forming roller, the forming roller is rotationally connected in the frame body, a spiral forming groove is formed in the peripheral side, a pressing mechanism is arranged in the frame body, and the pressing mechanism comprises a pressing wheel, a spiral pressing groove, a tensioning wheel and a transmission toothed belt. According to the rectangular spring forming equipment, the contact pressure of the spiral pressing groove on the pressing wheel and a steel wire in the spiral forming groove on the forming roller is adjusted by rotating an adjusting bolt, the driving motor and the transmission toothed belt drive the pressing wheel and the forming roller to synchronously and reversely rotate, the spiral pressing groove always keeps an extrusion state on the winding working end of a rectangular spring in the whole process of the spiral forming groove, the winding traction force of a steel wire raw material is greatly improved, and the machining quality of the rectangular spring is guaranteed.

Description

Technical field [0001] The present invention relates to the technical field of rectangular spring production equipment, and more particularly to a rectangular spring forming apparatus. Background technique [0002] The rectangular spring material section is rectangular, which is very suitable for a high load, and the space is very limited, in line with high speed compression and overweight load. The existing molding apparatus of the rectangular spring is prepared in the molding of a rectangular spring, and is usually fixed using the squeezing block on the wire feedstock on the molding roller, which is extruded at the rotation of the molding roller. The block is a relatively sliding friction with the wire feedstock, affecting the rectangular spring is wound; at the same time, the rectangular spring is fixed to the rectangular spring is not uniform, due to the high elasticity of the steel wire, easy to make the rectangular spring due to the force of the force After the production, ...

AI Technical Summary

Problems solved by technology

Existing rectangular spring forming equipment using rectangular steel wire as raw material usually uses extrusion blocks to fix the steel wire raw material on the forming roller during the forming and preparation of the rectangular spring. In this way, when the forming roller rotates, extrusion The relative sliding friction between the block and the steel wire material will affect the winding shape of the rectangular spring; at the same time, the fixed force on the initial winding end of the rectangular spring is not uniform. springback deformation
