The specific embodiment
In order to further specify principle of the present utility model and structure, now by reference to the accompanying drawings preferred embodiment of the present utility model is elaborated.
Fig. 1 is the front view of the flatten mechanism embodiment of the utility model strip, and Fig. 2 is the birds-eye view of this embodiment, and Fig. 3 is the left view of embodiment.
The flatten mechanism embodiment of the utility model strip is that two cover mechanisms are corresponding arranges, and every cover mechanism can be divided into roll extrusion section and loading section.This structure can realize the function that the pole piece strip flattens, and improves the accuracy rate of the correction origin position of correlation inductor detection, thereby improves the coiling precision.
As shown in the figure, roll extrusion section is provided with axially parallel and radially corresponding lower compression roller 2 and upper pressure roller 5, acts on respectively the front and back of strip 10.Loading section is provided with the torsion shaft 13 of the upper pressure roller 5 that drives roll extrusion section, for upper pressure roller 5 provides the moment of torsion that strip 10 is exerted pressure; The axis of torsion shaft 13 is parallel with the axis of pressure roller.
Roll extrusion section comprises: base 1 and pressure roller bearing 6.
The base 1 that is fixedly installed is positioned at the back side of strip 10.The base 1 of two cover mechanisms, its aspectant inner edge is separately installed with lower compression roller 2, and lower compression roller 2 is installed in the inner edge of base 1 by lower roller shaft 3 and bearing 14.The pivot center of lower compression roller 2 is substantially vertical with the direction of travel of strip 10, and the cylinder of lower compression roller 2 contacts with the back side of strip 10, generally is the line contact.
Be positioned at the pressure roller bearing 6 in the front of strip 10.The root of two pressure roller bearings 6 is connected on the torsion shaft 13 of loading section, is fixed on the torsion shaft 13 by clamp lever 11.Pressure roller bearing 6 is with respect to the fixed position of torsion shaft 13, and is axially adjustable.The end of pressure roller bearing 6 is equipped with pressure roller 5, and upper pressure roller 5 is installed in the end of pressure roller bearing 6 by upper roll shaft 4 and bearing 14, and the axial length of upper pressure roller 5 far is shorter than the axial length of lower compression roller 2.The effect of pressure roller bearing 6 is that the torque conversion that torsion shaft 13 transmission are come is the thrust that upper pressure roller 5 acts on strip 10 fronts.
