Hot coil spring forming system

Abstract

The invention relates to a hot coil spring forming system. The hot coil spring forming system comprises a wire feeding part, a guide part and a winding part. The wire feeding part is composed of a plurality of upper rolling wheels and lower rolling wheels which are oppositely arranged in the vertical direction. The guide part is arranged downstream of the wire feeding part. The winding part comprises a cutter core shaft, a lower ring diameter rod, an upper ring diameter rod, a cutter and a pitch rod, wherein the lower ring diameter rod, the upper ring diameter rod, the cutter and the pitch rod are sequentially arranged around the core shaft. In addition, the hot coil spring forming system further comprises a wire heating part arranged between the wire feeding part and the guide part. The wire heating part comprises an induction coil and an alternating current power supply. The induction coil converts electric energy supplied by the alternating current power supply into heat energy so as to heat the wire rod passing through the induction coil and increase the temperature. In the wire rod conveying process, the wire rod is subjected to heating treatment, so that the temperature value of the wire rod in the winding forming process is improved, the elastic recovery value after spring forming is effectively reduced, the forming stability is ensured, and good preparation is carried out for the smooth development of later assembly work.

Description

technical field [0001] The invention relates to the technical field of spring manufacturing, in particular to a hot coil spring forming system. Background technique [0002] Inductive spring coils are devices that use the principle of electromagnetic induction to work. When a current flows through a wire, a certain electromagnetic field will be generated around the wire, and the wire itself of this electromagnetic field will induce the wire within the range of this electromagnetic field. Inductive spring coils are widely used in the manufacturing industry of electronic components, and are generally wound and formed by means of spring machines. The highly conductive wire used to make the inductance spring coil is relatively thin (less than 2mm), which occurs during actual use. The inductance spring coil is prone to a certain degree of elastic recovery at one end after winding and forming, which affects its dimensional accuracy. , thus affecting the positioning and spot weld...
