Abstract

The invention discloses a spring machine wire feeding wheel and a wire feeding mechanism, which comprises a compression cam, an upper groove wheel, a lower groove wheel, a steel wire grip block and a slide block, wherein the compression cam is fixedly installed on a rotating shaft and driven by a servomotor, the upper groove wheel and the lower groove wheel are vertically arranged, the steel wire grip block is used for gripping steel wires, the slide block always close contacts the compression cam and is fixedly connected with the rotating shaft of the upper groove wheel, a curve arc slots matched with the maximum outside diameter of the steel wires is are arranged on the outer circumferences of the upper groove wheel and the lower groove wheel, and the each curve arc slot comprises a first curve arc segment, a second curve arc segment and a third curve arc segment, wherein the second curve arc segment is positioned between the first curve arc segment and the third curve arc segment, and the axial height of the second curve arc segment is lower, so a notch is formed.

Description

technical field [0001] The invention relates to parts on a spring machine, in particular to a wire feeding wheel and a wire material feeding mechanism of the spring machine. Background technique [0002] The spring machine of prior art generally all is made up of mechanisms such as machine platform, gear box transmission system, array knife rest slide, spring wire material feeding system, microcomputer control system and array air pressure auxiliary device. For example, Chinese patent CN2174276Y discloses a kind of "universal automatic spring machine", which includes eight groups of knife rest slides braked by cam plates, air pressure assist, gear transmission system, wire material feeding system, and microcomputer control system. to make. Tool holders and knives with different or the same functions are installed on the tool holder sliding seat arranged in the shape of rice characters, and various different or identical cams are used, so that after the spring wire is sent o...
