Abstract

The utility model relates to a telescopic coil winding mould which is mainly used for winding coil of an electric motor, an electric transformer, etc. A mould body of the telescopic coil winding mould is composed of a block mould (6) and a block mould (7). The utility model is provided with a block mould telescoping mechanism which is composed of a screw connection seat (10), a two-way spiral shaft (11) and a guide bar (12). The mould body is connected with the block mould telescoping mechanism by the screw connection seat. The block mould is provided with a screw rod (13) whose one end is sheathed in a slide plate (17). The two-way spiral shaft can be rotated to make the block mould shrink along an axial line (16) direction, and the winding coil can be taken out without dismounting the mould. The two-way spiral shaft can be oppositely rotated to make the block mould in a winding state. The utility model has the advantages of simple operation and easy use, and can increase productivity.

Description

Telescopic coil winding mould

The utility model relates to a kind of coil winding mould.

In the motor manufacture process, stator coil at first needs coiling on forming mould, then it is embedded in the wire casing of stator.Existing winding former structure is seen Fig. 1, and mould is made up of several piece matrix (1).Matrix is loaded on the rotation axis, by briquetting (2), compresses with nut.Winding slot (3) is arranged on the mould, and wire jumper groove (4) is used for the more groove of line, and the threading after binding groove (5) is used for coil and turns around is pricked and tied up.Rotating shaft is rotated, and line turns around with mould, pricks after winding by the required number of turn and ties up.Back out nut then, entire die is unloaded, can take out coil.Upward fix owing to need that at first matrix is loaded on axle, need after the coiling matrix is unloaded the taking-up coil, thereby operation is many, troublesome poeration, production efficiency is low.

The purpose of this utility model provides a kind of telescopic coil-winding mould, utilizes the flexible of piece mould, need not take apart a die, and can take out coil easily, and operation simplifies the operation.

The technical solution of the utility model is seen Fig. 3, forms die body by piece mould (6), piece mould (7), and winding slot (8), binding groove (9) are arranged on the die body; Piece mould telescoping mechanism is set, and this mechanism is made up of be threaded seat (10), two-way spiral shell axle (11), guide post (12); Die body is connected in piece mould telescoping mechanism by the seat that is threaded; Establish screw rod (13) in two modules, screw rod is inserted in the slide plate (17) to be fixed with nut.Mould is made up of die body and telescoping mechanism, and entire die is connected in by bearing (14) in the rotating shaft (rotating disk) of coil winding machine, each part and each several part be connected and structure is provided fully by Fig. 3, Fig. 4.After the pitch of the laps coiling, unscrew nut (15), rotate two-way spiral shell axle, because seat (10) effect that is threaded drives the piece mould and moves screw rod (13) slippage in the chute of slide plate (17) to mold axis (16) direction.Contract in the piece mould, can take out coil.The two-way spiral shell axle of backward rotation resets to fully around state the piece mould.

Fig. 1 is existing winding former structure chart;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is the utility model structure chart, and is appointed as the specification digest accompanying drawing;

Fig. 4 is Fig. 3 left view.

Embodiment is referring to Fig. 3, Fig. 4.The piece mould is wooden by high-quality, and establish metallic support (18), and present embodiment is established guide post (12), (19) (referring to Fig. 4), and seat (10) plays the guide holder effect simultaneously except that being threaded, also be provided with fairlead (20) on the die body, present embodiment is a Y132 type coil of stator of motor winding former.

The utility model at first is designed to two piece moulds with the die body of mould, then die body is connected on the telescoping mechanism, rotate the two-way spiral shell axle in the telescoping mechanism, the piece mould is shunk to the mold axis direction, need not take apart a die, can take out easily coil, operation simplifies the operation, easy to use, boost productivity. The coil winding that also can be used for the products such as transformer.
