Description

(54) FRONT FOR WINDING NON-CASTED SOBINS

one

The invention relates to process equipment for the regular winding of frameless bobbins of wire or microcable and can be used in electrical engineering.

A known mandrel for fastening a plurality of coils, comprising several separate coil holders mounted on a common shaft. The bow of the holder fixes in the axial direction the end of the corresponding coil and the end of the next coil

However, one end of each holder enters the recess, made at the end of the next adjacent holder, as a result of which the coil holders are locked in order. This mandrel is designed to wind several separate separately 20 frame coils at a time. Configuration de); Residents are complicated, they are fucked by the precision of manufacturing.

The most (close to the technical essence and the achieved result 25 to the proposed is the installation, for the winding of wire coils containing wires, containing sleeves mounted coaxially on the shaft and separated by {removable disks f2j-30

 However, the design of this device, tpe6VeT, is an additional step for assembling a support.

The purpose of the invention is to simplify the design.

The goal is achieved by the fact that the outer surface of each sleeve is made conical d with an annular collar located on the side of a larger diameter of the cone, and in each of the removable disks there is an annular recess below the collar of the sleeve and a groove directed along the tangent to the recess.

On schematically depicted mandrel, common Vice; figure 2 - section aa in figure 1; on fig.Z - view along arrow B in figure 2.

The mandrel consists of a shaft 1, sleeves 2 with a conical outer surface and removable discs 3. Bushings 2 sticks are a nut with a nut 4. Each sleeve 2 has an annular collar 5 located on a larger cone diameter that has a yrtdpa removable disk that has an annular recess 6 under this collar sleeve. removable. the disk 3 has a groove 7, which is BYPOL-. yen on a cylindrical surface; er6 with the transition to the face surface of the disk in the direction along the Tangent to the circumference of the circular you, point 6.; ..

Winding the wire to the mandrel is as follows.

The end of the wire is clamped between the head of the plug 1 and the outermost disk 3. Along the slot 7 of this disk, the wire is pulled to the sleeve 2 and is pulled onto it in a row. When winding the first row, the next disk 3 is pressed by the turns of the wire to the shoulder 5 of the sleeve, while further winding remains in this position

In the process of winding, the coils of the pierce are fastened with adhesive tape. After the n: aio ki of the first reel, the wire from the outer coil: placed next to the second disk 3 along slot 7 on this disk is led to the next one (its sleeve 2. - ::. -.,.,:, V., Further, the yamotka prbtsoy is the same order as in the case of the first reel, and repeats N times, ie, as much as the reels connected with the mead, it is necessary to wind it from one piece of wire.

After winding a bobbin on a mandrel, It is dried, then removed from it. For this, the nut 4 is turned off and the shaft 1 is taken out. The reels on the bushes 1 with one disc 3 are separated from each other. Then each reel is alternately mounted vertically (removable disk down) on

{stand for removal. By acting from above with some force on the end of the tapered sleeve 2, it moves downward relative to the reel and removable disk 3, after which the reel can be easily removed from the sleeve, and the circuit disk is separated.

The proposed mandrel is structurally simple, easy to use. It allows you to wind a number of reels from a single piece of wire, which makes it possible to eliminate the connection of reels by splicing the wire.
