Problems solved by technology
Therefore, after the bare copper flat wire is accurately controlled by the mold, due to uneven force, the flat wire is pulled, resulting in a change in size, small waist, and out-of-tolerance problems. The original 220KV transformer coil has no strict requirements on this, but now 500, 750 and million volt UHV products have strict requirements for this. The original pay-off system had major quality risks and could no longer meet the production requirements of bare copper flat wires.

Embodiment Construction
[0012] A compensatory gentle pay-off control device for bare copper flat wire according to the present invention, see figure 1 , the control device includes a slide rail 1, a pulley 2 and a counterweight 3, the slide rail 1 is erected, and the pulley 2 that can move up and down along the slide rail 1 is arranged on the slide rail 1. A steering wheel 5 is arranged on the top of the slide rail 1 , and the pulley 2 is connected with the counterweight 3 through a slide cable 4 passing through the steering wheel 5 . The weight of the counterweight 3 can be adjusted according to the tension of the bare copper flat wire to keep the stress on the bare copper flat wire roughly balanced.
[0013] figure 2 It is the use state diagram of the present invention. The present invention is arranged between the pay-off reel 6 and the traction motor 7, and the bare copper flat wire 8 passes through the middle hole of the pulley 2. Once the force is increased, the pulley 2 will move downward t...

The invention discloses a compensatory type bare copper flat wire paying-off control device which comprises a sliding rail, a pulley wheel and a clump weight. The sliding rail is vertically arranged and the pulley wheel which can slide up and down along the sliding rail is arranged on the sliding rail; and the pulley wheel is connected with the clump weight through a slip rope. The compensatory type bare copper flat wire paying-off control device for one thing offsets the influences of unstable stress and for the other thing eliminates the influences of shaking and resonance of the wire; and the bare copper flat wire is evenly tensioned constantly, so the contour dimension of the bare copper flat wire is stable.
Description
technical field [0001] The invention relates to a supporting equipment for the production of bare copper flat wires, in particular to a compensatory gentle pay-off control device for bare copper flat wires. Background technique [0002] The production of bare copper flat wire requires strict size control, and the error generally cannot exceed ±0.05mm. In the case of multi-channel mold control size, the force on the wire must be uniform, otherwise the size of the wire will be large or small, which will seriously affect the wire. quality performance. The traditional bare copper flat wire pay-off mechanism is relatively rigid, the wire is loose or tight, and the force cannot be kept uniform, which is the main source of the wire size error. [0003] The bare copper flat wire is subjected to uneven force during the unwinding process. On the one hand, when the traction motor rotates, the wire slips on its surface; The force on the flat wire fluctuates. Therefore, after the bare...
