Abstract
The invention discloses an enameled flat wire manufacturing method, which comprises the steps of setting a reinforcing device on an enameled flat wire running path. The reinforcing device comprises an upper roller group and a lower roller group. The upper roller group and the lower roller group are arranged in a staggered manner and are respectively arranged on the upper side and the lower side of an enameled flat wire. Upper rollers in the upper roller group are pressed against the upper side of the enameled flat wire. Lower rollers, corresponding to the upper rollers in the upper roller group, in the lower roller group are pressed against the lower side of the enameled flat wire. A pay-off reel for the enameled flat wire is arranged at the front end of the reinforcing device. A take-up reel for the enameled flat wire is arranged at the rear end of the reinforcing device. The enameled flat wire enters from the front end of the reinforcing device, is led out from the rear end of the reinforcing device, and is wound and taken up by the take-up reel. The enameled flat wire manufacturing method has the advantages that the yield strength of the enameled flat wire can be improved, the yield strength along the direction of the length of the entire enameled flat wire is stable, and the external dimension of the enameled flat wire is not greatly changed and meets the requirement.
Description
Technical field
The present invention relates to a kind of transformer enameled sheet wire processing method, specifically a kind of method that improves the enameled sheet wire yield strength.
Background technology
Enameled sheet wire is owing to become soft attitude copper cash through high-temperature baking, and hardness greatly reduces, and causes the yield strength of enameled sheet wire often lower.And ultra high voltage, special transformer are had relatively high expectations to the bending resistance moment of coil, and namely the yield strength of enameled sheet wire must reach 150 ~ 180 considerably beyond 90 ~ 120 typical values, even surpass 200.
At present, improving enameled sheet wire yield strength traditional method is that whole dish enameled sheet wire is placed on unwrapping wire on the admission machine, the another one blank panel twines take-up, enameled sheet wire certain pressure in addition in the folding and unfolding process, enameled sheet wire is under pressure, flecition, soft attitude copper becomes hard attitude copper, and yield strength is improved.But yield strength is reached about 180, then need to carry out repeatedly the retractable cable operation.In addition, along with the change of yield strength is big, impressed pressure and tractive effort are easy to make enameled sheet wire to be out of shape, and overall dimension is dwindled, and influences tack and the insulation property of insulation paint film, also influences the voltage capacity of coil.
Summary of the invention
In order to overcome the problem that prior art exists, the processing method that the purpose of this invention is to provide a kind of enameled sheet wire, can improve the enameled sheet wire yield strength by this method, and yield strength is stable on whole enameled sheet wire length direction, the overall dimension of enameled sheet wire then changes not quite, meets the requirements.
The objective of the invention is to be achieved through the following technical solutions:
A kind of processing method of enameled sheet wire is characterized in that this method may further comprise the steps:
1) at the enameled sheet wire working line stiffening device is set, described stiffening device comprises upper roller group and bottom roller group, and described upper roller group and bottom roller group are staggered and lay respectively at enameled sheet wire both sides up and down; Upper roller in the upper roller group is pressed on the upside of enameled sheet wire, and the bottom roller in the bottom roller group corresponding with the upper roller in the upper roller group is pressed on the downside of enameled sheet wire;
2) draw drum of enameled sheet wire is arranged on the front end of stiffening device; The take-up reel of enameled sheet wire is arranged on the rear end of stiffening device;
3) enameled sheet wire is entered by the stiffening device front end, is drawn by the stiffening device rear end, and twines take-up by take-up reel.
In the stiffening device of the present invention, the quantity of upper roller is regulated according to enameled sheet wire overall dimension in the upper roller group, and the quantity of bottom roller is regulated according to enameled sheet wire overall dimension in the bottom roller group; In the upper roller group in the installation site of upper roller and the bottom roller group installation site of bottom roller can regulate.Spacing between upper roller group and the bottom roller group is regulated according to the needed pressure of enameled sheet wire.
The present invention is a kind of processing method that improves the enameled sheet wire yield strength, by two groups of staggered roller set, the enameled sheet wire that feasible centre is passed through is crooked back and forth, by regulating the spacing of two groups of rollers, enameled sheet wire is applied the pressure of different sizes, enameled sheet wire crawls by roller set under the effect of tractive effort, and enameled sheet wire soft attitude copper under pressure, flecition becomes hard attitude copper, and yield strength is improved.
The present invention can improve the enameled sheet wire yield strength effectively, and stiffening device can be according to the actual conditions of enameled sheet wire, interim installation, fine adjustments.And the enameled sheet wire that obtains yield strength on whole enameled sheet wire length direction is stable, and the overall dimension of enameled sheet wire then changes not quite simultaneously, meets the requirements.
The present invention has overcome the original yield strength instability that always exists, it is lead one section hard, one section soft drawback, particularly the control of big yield strength is comparatively reliable, the yield strength of enameled sheet wire can reach 210, the overall dimension of enameled sheet wire then changes not quite, in the reasonable tolerance scope.
Description of drawings
Fig. 1 is enforcement schematic diagram of the present invention.
Embodiment
A kind of processing method of enameled sheet wire is seen Fig. 1, and this method may further comprise the steps:
1) at the enameled sheet wire working line stiffening device 1 is set, stiffening device 1 comprises upper roller group 11 and bottom roller group 12, and upper roller group and bottom roller group are staggered and lay respectively at enameled sheet wire about in the of 3 both sides; Upper roller 111 in the upper roller group is pressed on the upside of enameled sheet wire, and the bottom roller 121 in the bottom roller group corresponding with the upper roller in the upper roller group is pressed on the downside of enameled sheet wire;
2) draw drum of enameled sheet wire is arranged on the front end of stiffening device; The take-up reel of enameled sheet wire is arranged on the rear end of stiffening device;
3) enameled sheet wire is entered by the stiffening device front end, is drawn by the stiffening device rear end, and twines take-up by take-up reel.
Roller set quantity can be regulated according to yield strength size and enameled sheet wire overall dimension, and is the amount doesn't matter, namely can use by a plurality of pulley block in series, to reach the purpose of rapid raising yield strength.The quantity of roller also can be regulated according to enameled sheet wire overall dimension in the single roller set simultaneously.
Two groups of assembly pulleys are staggered up and down, can spacing, and make the enameled sheet wire pressure that passes wherein to be effectively controlled.
Because the rotation of roller, the enameled sheet wire pressure is even and the stressed size of surperficial each part of lenticular wire is consistent, and enameled sheet wire overall dimension changes less like this.
