Abstract
The utility model discloses a device for improving yield strength of enamelled rectangular wires. The device comprises upper roller groups and lower roller groups both in staggered arrangement and respectively positioned on the upper sides and the lower sides of enamelled rectangular wires, wherein upper rollers in the upper roller groups are propped against the upper sides of the enamelled rectangular wires, and lower rollers in the lower roller groups corresponding to the upper rollers in the upper roller groups are propped against the lower sides of the enamelled rectangular wires. By adopting the device provided by the utility model, the yield strength of the enamelled rectangular wires can be easily and effectively improved; the yield strength in the length direction of the integral enamelled rectangular wires is stable and can maximally reach up to 210; and the overall size of the enamelled rectangular wires changes little and conforms to the requirement.
Description
Technical field
The utility model relates to a kind of transformer enameled sheet wire processing unit (plant), specifically a kind of device 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 promptly 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 in addition pressure 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 reach yield strength about 180, then need 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 the 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 purpose of this utility model provides a kind of device that improves the enameled sheet wire yield strength, this device can improve the enameled sheet wire yield strength simply, efficiently, and yield strength is stable on whole enameled sheet wire length direction, and yield strength can reach 210; The overall dimension of enameled sheet wire then changes not quite simultaneously, meets the requirements.
The purpose of this utility model is achieved through the following technical solutions:
A kind of device that improves the enameled sheet wire yield strength is characterized in that: this 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, is pressed on the downside of enameled sheet wire with the bottom roller in the corresponding bottom roller group of the upper roller in the upper roller group.
In the utility model, the equal scalable of quantity of bottom roller in the quantity of upper roller and the bottom roller group in the upper roller group.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.
Spacing between the utility model upper roller group and the bottom roller group is regulated according to the needed pressure of enameled sheet wire.The equal scalable in installation site of bottom roller in the installation site of upper roller and the bottom roller group in the upper roller group.
The utility model is a kind of raising enameled sheet wire yield strength device of simple and efficient, with 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 utility model simple and effective is convenient to install, dismantle, can be according to the actual conditions of enameled sheet wire, and interim installation, fine adjustments.Can improve the enameled sheet wire yield strength simply, efficiently, and yield strength is stable on whole enameled sheet wire length direction, the overall dimension of enameled sheet wire then changes not quite simultaneously, meets the requirements.
The beneficial effects of the utility model are: the control of enameled sheet wire yield strength is easier, efficient, 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 a structural representation of the present utility model.
Embodiment
A kind of device of raising enameled sheet wire yield strength described in the utility model is seen Fig. 1, and this device comprises upper roller group 1 and bottom roller group 2, and upper roller group 1 and bottom roller group 2 are staggered and lay respectively at enameled sheet wire about in the of 3 both sides; Upper roller in the upper roller group 1 is pressed on the upside of enameled sheet wire 3, is pressed on the downside of enameled sheet wire 3 with the bottom roller in the corresponding bottom roller group 2 of the upper roller in the upper roller group 1.
Roller set quantity can be regulated according to yield strength size and enameled sheet wire overall dimension, and is the amount doesn't matter, promptly 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.
The utility model simple and effective is convenient to install, dismantle, can be according to the actual conditions of enameled sheet wire, and interim installation, fine adjustments.
