Abstract
The utility model relates to a foil tension device for a foil-type winding machine of a transformer and relates to the technical field of transformers and the foil tension device can be used for overcoming the defect that the electrical performance of a coil is influenced due to the uneven tension degrees among the layers of the coil in the existing foil coil winding technology. According to the technical scheme, the foil tension device comprises a base, a cylinder and a rocker and is characterized in that the lower end of the cylinder is connected with the base by virtue of a movable hinge of the cylinder, a piston of the cylinder is connected with the middle part of the rocker by virtue of a movable hinge of the piston, the lower end of the rocker is connected with the base by virtue of a movable hinge of the rocker, and idler wheels are arranged at the upper end of the rocker. Through controlling the pressure of the cylinder, the foil tension device can be arranged at one end of a coil winding roller of the transformer so as to adjust the pressure on the foil layers of the coil, and can be arranged at one end of a foil unwinding roller of the transformer so as to adjust the tension force for unwinding the coil. According to the foil tension device, foil sheets are flat and uniform when being sent out, the tension of the foil layers are proper when the coil is wound, the uneven tension among the coil layers is avoided, and the foil coil winding speed is enhanced.
Description
Technical field
The utility model belongs to the transformer technology field, is specifically related to a kind of transformer foil formula coil winding machine foil tensioning apparatus.
Background technology
Transformer is in running; Because the lead of coil receives electrodynamic effect can produce vibrations; For the uneven transformer of coil interlayer degree of tightness; Its insulation property tend to the destruction of the power that is given a shock, so transformer coil has higher requirements to the coil layer degree of tightness uniformity in winding process, particularly the foil coil.Existing foil coil winding machine is when coil winding, because the Copper Foil width is bigger, formed mechanical tension is also big; During coil winding not only the coil cylinder can produce and beat, foil unreels cylinder and also can produce and beat, and makes foil relaxation by a relatively large margin occur; The coil degree of tightness of coiling is uneven, not only makes the coil physical size wayward, and because turn-to-turn very easily produces loosening; Have a strong impact on the electric property of coil, make transformer in running, have potential safety hazard.
Summary of the invention
The purpose of the utility model is to overcome the coil interlayer degree of tightness inequality that exists in the existing foil coil winding technology; Influence the deficiency of coil electric performance; A kind of coil interlayer degree of tightness uneven phenomenon can stop the foil coil winding time is provided, improves the transformer foil formula coil winding machine foil tensioning apparatus of coil winding speed.
For achieving the above object, the technical scheme of the utility model comprises base, oil cylinder and rocking arm.It is characterized in that: the lower end of oil cylinder is connected on the base through the oil cylinder hinges, and the oil cylinder hinges can rotate on base flexibly; The piston of oil cylinder is connected the middle part of rocking arm through the piston hinges, and the piston hinges can rotate on rocking arm flexibly.The lower end of rocking arm is connected on the base through the rocking arm hinges, and the rocking arm hinges can rotate on base flexibly; The upper end of rocking arm is provided with 2 and is merely able to the roller of rotation flexibly.2 rollers during this device busy on the rocking arm are pressed on the foil.
The beneficial effect of the utility model is: this device plays lasting pressuring action, the isostasy that can regulate the pair of rollers foil.Device both can be used on the pressure of transformer coil winding cylinder one end regulating winding foil layer, also can be used on foil and unreeled the relaxation power that cylinder one end adjusting foil unreels.Make smooth when the foil sheet is emitted, even; Foil layer degree of tightness degree of having during coil winding is stopped coil interlayer degree of tightness uneven phenomenon, improves foil coil winding speed.
Description of drawings
Fig. 1 is the structure chart of facing of the utility model;
Fig. 2 is the right TV structure figure of the utility model.
In the accompanying drawing: 1. rocking arm, 2. rocking arm hinges, 3. roller, 4. oil cylinder, 5. oil cylinder hinges, 6. base, 7. piston, 8. piston hinges, 9. foil.
Embodiment
As depicted in figs. 1 and 2, the lower end of oil cylinder 4 is connected on the base 6 through oil cylinder hinges 5, and oil cylinder hinges 5 can rotate on base flexibly; The piston 7 of oil cylinder is connected the middle part of rocking arm 1 through piston hinges 8, and piston hinges 8 can rotate on rocking arm flexibly.The lower end of rocking arm 1 is connected on the base 6 through rocking arm hinges 2, and rocking arm hinges 2 can rotate on base flexibly; The upper end of rocking arm 1 is provided with 2 and is merely able to the roller 3 of rotation flexibly.
This device can be used on the pressure of transformer coil winding cylinder one end regulating winding foil layer, also can be used on foil and unreels cylinder one end and regulate the relaxation power that foil unreels, and also can unreel cylinder one end at transformer coil winding cylinder one end and foil and use simultaneously.During transformer coil winding, oil cylinder 4 is a fulcrum with oil cylinder hinges 5, through the charge oil pressure of oil cylinder piston 7 is released; Piston 7 promotes rocking arms 1 through piston hinges 8; rocking arm 1 is a fulcrum with rocking arm hinges 2, promotes 2 cylinders 3, makes it all the time to press with suitable pressure to be attached to the coil winding cylinder and foil unreels on the foil 9 on the cylinder; along with the continuous rotation of coil winding cylinder, the coiling of completion transformer foil coil.
