Wire feeding device for spring processing

Abstract

The invention relates to a wire feeding device for spring processing and belongs to the technical field of basically non-cutting machining or processing metal machines for manufacturing spring wires through wires. The wire feeding device for spring processing is sequentially provided with a wire wheel, a straightening mechanism, a reduction gearbox and a plurality of sets of wire delivery wheels located in the reduction gearbox. The straightening mechanism comprises a pair of pre-fixing wheels, a pair of sheaves and a pair of rotary shafts, wherein the pair of pre-fixing wheels is installed on a set of pre-fixing bearing pedestals; the pair of sheaves is installed on a set of straightening bearing pedestals; the pair of rotary shafts abuts against the outer sides of the pair of straightening bearing pedestals correspondingly; and a steel wire straightened by the straightening mechanism is fed into the reduction gearbox and delivered out through the wire delivery wheels in the reduction gearbox. The wire feeding device for spring processing is applied to spring processing and has the advantages that two-way distance adjusting is achieved, the center line is stable and wire feeding is smooth.

Description

technical field [0001] The application relates to a wire feeding device for spring processing, which belongs to the technical field of metal machinery for processing or processing spring wires made of wires without cutting. Background technique [0002] Springs are used in mattress processing, spring machinery, hardware and electrical appliances, etc. For ordinary equipment, the processing accuracy of springs is not high. Such as spring machinery), processing precision (such as hardware and electrical appliances, etc.) requirements are getting higher and higher, especially for small wires below 0.5mm, ordinary processing equipment is very likely to cause uneven wire pulling, jitter and other phenomena, resulting in the wire cannot be transported stably , The length of the wire feeding is uneven, so that in the process of processing the spring, the accuracy of the spring will be reduced due to the unevenness of the wire. [0003] The spring processing process is mainly summa...

Problems solved by technology

Although this method realizes the processing of steel wires with different diameters, however, because one of the two rollers moves at a certain rate, the change of one side position is very easy to cause the change of the center position, so that the steel wires are aligned on both sides during the straightening process. Different degrees of phenomenon, the processing accuracy is seriously reduced
