Problems solved by technology

During production, the pitch of the spring needs to be pushed back, and the deformation resistance of the thick-diameter steel wire is very large, so that the feeding wheel is subjected to a large axial force, and the steel wire shakes a lot in the last few turns, so it is difficult to fix it with the set screw The axial position causes the axial movement of the feeding wheel, affects the feeding accuracy and spring forming accuracy, and affects the product qualification rate, and the size and weight of the feeding wheel are large, so the moment of inertia is large, the response is slow, and the production cycle is limited.
In addition, large-sized feeding wheels also use a lot of materials, and the manufacturing cost is also high

Abstract

The invention relates to a feeding and positioning component of a spring coiling machine, which comprises a feeding wheel, a positioning shaft sleeve, an expansion taper sleeve and a pressing ring. The feeding wheel is only provided with two arc grooves equally spaced from end faces, the thickness of the feeding wheel is greatly decreased, and a positioning device comprises the positioning shaft sleeve, the expansion taper sleeve and the pressing ring and is used for axially and radially positioning and clamping the feeding wheel. Compared with the prior art, the feeding and positioning component solves the problem of axial deviation of an original feeding wheel in operation and leads feeding to be more stable and accurate, the overall weight of the feeding wheel and the positioning device is only 2 / 3 of that of an original structure, inertia is decreased, the driving burden of a machine tool is relieved, frequent speed change and reversing are facilitated, the structure of the feeding wheel is simplified, consumption of high-alloy steel is greatly reduced, and material cost and machining cost are saved.

Description

technical field [0001] The invention relates to a feeding positioning assembly, in particular to a feeding positioning assembly of a coil spring machine. Background technique [0002] Most of the front suspension springs of cars are made of cold-drawn spring steel wire with a diameter of Φ11~Φ16mm, which is manufactured by cold rolling. The main equipment used for cold rolling this kind of suspension spring is CNC coiling machine. [0003] The existing feed wheel 6 of some CNC coil spring machines is connected with the feed shaft 1 by a flat key 8 and fixed by a screw 7. Its structure is as follows: Image 6 shown. During production, the pitch of the spring needs to be pushed back, and the deformation resistance of the thick-diameter steel wire is very large, so that the feeding wheel is subjected to a large axial force, and the steel wire shakes a lot in the last few turns, so it is difficult to fix it with the set screw The axial position causes the axial movement of the...
