Multiple wire feeder and spring coiler with same

Abstract

The invention discloses a multi-metal-wire conveying device and a spring coiling machine with the same. The multi-metal-wire conveying device comprises a rotating shaft, a first conveying wheel, a plurality of floating shafts and a plurality of second conveying wheels, wherein the first conveying wheel is mounted on the rotating shaft and rotates with the rotating shaft; and the plurality of second conveying wheels are in one-to-one correspondence with the plurality of floating shafts, each second conveying wheel is mounted on the corresponding floating shaft so as to rotate with the corresponding floating shaft, each second conveying wheel is oppositely arranged with the first conveying wheel so as to convey one corresponding metal wire in multiple metal wires, and each floating shaft canfloat and swing relative to the rotating shaft so as to adjust a clearance between the second conveying wheel mounted on the floating shaft and the first conveying wheel. According to the multi-metal-wire conveying device of the embodiment, the structure is simple, and the cost is low; and the rotating control of different second conveying wheels does not need to be switched when different metalwires are conveyed, so that the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of spring manufacturing, in particular to a conveying device capable of selectively conveying a plurality of metal wires and a spring coiling machine having the same for manufacturing springs for mattresses. Background technique [0002] In the mattress industry, springs for mattresses are usually manufactured on a spring coiling machine, in which the metal wire (usually steel wire) used to make the spring is transported to the spring forming mechanism by the conveying mechanism, and the spring forming mechanism shapes the wire into a spring. In the related art, the spring coiling machine uses a single metal wire to manufacture the spring, and the conveying mechanism can only convey the single metal wire, so the efficiency of manufacturing the spring is low. Also, when the diameter or hardness of the wire changes, another spring coiling machine is usually required, resulting in high cost. [0003] For this ...

AI Technical Summary

Problems solved by technology

Since each pair of wire-feeding rollers operates independently of each other, each pair of wire-feeding rollers needs to be driven by an independent driving source, and the number of driving sources increases. In addition, each wire-feeding roller needs a wheel shaft, so the number of wheel shafts increases, resulting in the wire-feeding mechanism The structure is complex and the cost increases

Moreover, since it is necessary to control each pair of wire feeding rollers to operate independently of each other, the control of the wire feeding mechanism is complicated and the efficiency is reduced.
