Detailed Description

The embodiment of the utility model provides a spring machine is with automatic defeated material mechanism, as shown in fig. 1-3, including steel wire 1, base 2, locate the unwrapping wire motor 3 at base 2 middle part, set firmly many guide posts 4 on base 2, leading wheel 5 is all installed at the top of guide post 4, swivel mount 13 rotates and installs on base 2, unwrapping wire motor 3 drive swivel mount 13 rotates, steel wire 1 is equipped with response buffer unit 6 by guide post 4 derivation end in proper order, tension adjustment unit 7, response buffer unit 6 and unwrapping wire motor 3 electric connection.

The routing direction of the steel wire 1 is shown in figure 3. The process of making the spring by the spring machine 12 needs to stop feeding the steel wire 1 for many times and shape the steel wire 1 to be produced, so the operation of the material conveying mechanism needs to be interrupted, otherwise, a large amount of steel wires 1 are easy to droop to cause knotting and can not operate.

This scheme is through response buffer unit 6 for stop the operation of unwrapping wire motor 3 when stopping the feeding of steel wire 1. The method comprises the following specific steps: the sensing buffer unit 6 comprises a guide rod 61 vertically arranged, a lifting block 62 movably sleeved on the guide rod 61, a first roller 63 positioned above and a second roller 64 positioned below, wherein the first roller 63 is pivoted on the guide rod 61, and the second roller 64 is pivoted on the lifting block 62.
