Description

State of technology

So far Winding devices are known, consisting of rectangular or square Bodies out Wood, plastic or light metal.

The Length of Winding device is usually by plates, the front side are fixed, limited to the lateral support of the winding.

at larger winding devices be in individual cases divided bodies used, the wedge-shaped against each other can be moved to the stripping the wound coil to achieve a pressure relief.

at the application of the winding creates a great pressure, especially for larger coils from the coil carrier on the winding device.

By this "shrinking" of the bobbin on the winding device is when pressing the coil a lot of effort necessary, which is especially air-cooled Coil designs often destroy the bobbin and Disintegration of the winding leads.

task

task the present invention is to provide a winding device, on the one hand the stability a solid body brings with it and on the other hand when removing the coil of the Winding device ensures relief in every direction in space, so that the stripping of the coil without much effort is possible, so that too air-cooled Coil designs are taken quickly and non-destructively can.

simultaneously the coil design should be made by precise milled in the support walls axially and radially non-positively supported be to the occurring forces to catch while winding.

function Description the winding device

The winding device consists of a hardened spindle ( 1 ) with hexagonal head and depending on the length of the coil to be wound with at least 3 circumferential, conical depressions, a threaded projection ( 2 ) and a bearing seat ( 2a ).

This spindle is located in a guide core ( 3 ) which is preferably executed in its cross-section square with sharply chamfered edges and on one side a threaded bushing ( 2 ) and opposite a bushing ( 2a ), as well as at least 12 pieces of guides for the pressure bolts ( 10 ), which are arranged at right angles to the spindle axis.

The hardened pressure bolts ( 10 ) are threaded on one side and conical on the other side according to the angle of the conical recesses in the spindle ( 1 ) and are with the threaded side in the trim strips ( 4 ), which are centered on the legs of the square guide core ( 3 ) and each with at least two Wegbegrenzugsschrauben ( 9 ) are fixed.

On the chamfered edges of the guiding core ( 3 ) are 4 in cross-section polygonal executed corner strips ( 5 ) and each with at least 2 Wegbegrenzungsschrauben ( 9 ) fixed with compression spring. The length of the guiding core ( 3 ) is replaced by a back wall ( 6 ) leading to the core ( 3 ) has a milled recess, with the contour and depth of the coil carrier to be wound and on the other side a driver device corresponding to the recording of the winding machine.

The other side of the guiding core ( 3 ) through the front wall ( 7 ), which also has a milled recess with the contour and depth of the bobbin to be wound, and a through hole for actuating the spindle by means of Steckschlüs sel.

On the other side, the front wall ( 7 ) via 2 holes for receiving the driving pins of the pressure piece ( 8th ).

The Item 10 described pressure piece is used for clamping the Wrapping device by means of tailstock and is with his 2 driving pin fixed in the front wall.

After inserting the bobbin or the 4 coil support segments in the cutout of the rear wall ( 6 ), the front wall ( 7 ) are placed so that the coil carrier segments or the coil carrier are received in the cutout.

By turning the spindle clockwise ( 1 ) by means of a socket wrench the trapezoidal strips ( 4 ) via the pressure bolts ( 10 ), which in turn moves the corner strips ( 5 ) diagonally spreads and thus the coil carrier, or the 4 coil support segments between the cut in front ( 7 ) and back wall ( 6 ) and the corner strips 5 ) clamped.

By turning the spindle to the left ( 1 ) by means of socket wrench are the pressure pin ( 10 ) and the trapezoidal strips ( 4 ) are made via the corner strips of the compression springs ( 9 ) under the travel limit screws ( 9 ) moved inwards into starting position.

By the detachable, frictional support the coil carrier Radial and axial, it is possible Coils also with big ones Wire sections non-destructive to wrap.

The winding device is variable, because by replacing the front ( 7 ) and back wall ( 6 ) with corresponding milled grooves as well as the 4 corner strips ( 5 ) with corresponding cross section, can be wound coils with square and rectangular core cross section.
