Abstract

The utility model discloses a winding die of an excitation stator coil of a power generator. The winding die consists of end dies on both sides, and a plurality of medium dies serially connected to a mandrel, wherein the mandrel has a stepped surface at one end, and butts against a nut through a adjusting cushion block at the other end; each of the end dies comprises an outer die part and a half inner die part on one side; each of the medium dies comprises an outer die part and half inner die parts arranged oppositely on both sides; the outer die part is the template structure of an original outer die; and the half inner die is the 1/2 template structure of an original inner die; the outer die part is tightened with the half inner die part as a whole; and the two adjacent half inner die parts are jointed at a bevel surface after assembling the die. According to the utility model, the inner die structure is divided smartly in such a manner that the inner die is cut obliquely and combined at the bevel surface to form the die structure easy to separate. Accordingly, the winding die provided by the utility model can be used for solving the technical difficulty in separating a formed coil and the inner die, and is convenient and quick in die assembling, and quick in die separation and removal; and the formed coil has the advantages of good appearance and high quality.

Description

The winding former of generator excitation stator coil

Technical field

The utility model relates to mechanism of power generation technology for making field, especially a kind of winding former of generator excitation stator coil.

Background technology

The coil of the excitation stator of generator need to utilize the winding former manufacturing.To shown in Figure 5, the winding former of existing excitation stator coil interval on mandrel 3 is in series with a plurality of external molds 2 and internal mold 1 such as Fig. 1, then utilizes adjusting cushion block 4 to push against in the end of mandrel 3 with nut 5, and external mold 2 is with internal mold 1 has certain thickness template.The winding former of this structure type, after enamelled wire is finished coiling, formed coil need to be separated with mould, but because in when coiling, enamelled wire and internal mold 1 be roll tightly fully identical, so pretty troublesome during separation, need utilize copper rod to knock internal mold 1 just can make formed coil separate with internal mold 1, not only internal mold 1 easily damages, and coil is also easily impaired, separates the aftershaping coil shape more random.

The utility model content

The applicant is for above-mentioned existing winding former demoulding difficulty, and easy shortcomings such as mold damage and coil provide a kind of winding former of generator excitation stator coil rational in infrastructure, thus fast peel of mould and coil.

The technical scheme that the utility model adopts is as follows:

A kind of winding former of generator excitation stator coil is connected on the mandrel by two side ends mould and some middle moulds and forms, and mandrel one end is step surface, and cushion block is regulated in other end utilization and nut pushes against; The end mould is comprised of half internal mold section of external mold section and a side; Middle mould is comprised of the half internal mold section that external mold section and both sides are oppositely arranged; Described external mold section is the formwork structure of former external mold, and described half internal mold section is 1/2 formwork structure of former internal mold, and external mold section and half internal mold section are fastened as a whole, and adjacent two halves internal mold section engages on the inclined-plane behind the die assembly.

As further improvement in the technical proposal: described half internal mold section be former internal mold by a template center through internal mold, and with the horizontal plane inclination angle be 1/2 formwork structure of the rear acquisitions that symmetrical plane dissects of 30～60 degree.

The beneficial effects of the utility model are as follows:

The utility model has decomposed internal model structure dexterously, internal mold cut sth. askew make up on the inclined-plane after decomposing, formed and separated easy mould structure, solved the technical problem of formed coil and internal mold separation difficulty, not only die assembly is convenient and swift, separated demolding is very fast, and the formed coil profile is neat, good product quality.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described.

As shown in Figure 6, the winding former of generator excitation stator coil described in the utility model is connected on the mandrel 3 by two side ends mould 6 and some middle moulds 7 and forms, and mandrel 3 one ends are step surface, and other end utilization is regulated cushion block 4 and pushed against with nut 5.Such as Fig. 7, shown in Figure 8, end mould 6 is comprised of half internal mold section 9 of external mold section 8 and a side; Such as Fig. 9, shown in Figure 10, middle mould 7 is comprised of external mold section 8 and the half internal mold section 9 that both sides are oppositely arranged; Above-mentioned external mold section 8 is the formwork structure of former external mold 2, half internal mold section 9 be former internal mold 1 by a template center through internal mold 1, and with the horizontal plane inclination angle be 1/2 formwork structure of the rear acquisitions that symmetrical plane dissects of 30～60 degree.External mold section 8 and half internal mold section 9 adopt the mode of gummed or securing member locking to be assembled into one.

During the mould assembling, step surface one end at mandrel 3 puts a slice end mould 6 first, then according to the coil winding requirement of excitation stator, sheathed some middle moulds 7, middle mould 7 and the end mould 6 between, utilize the inclined-plane 10 of half internal mold section 9 to connect between adjacent two middle moulds 7, thereby formed external mold and the internal model structure of space, installed at last end mould 6 additional and adopt adjusting cushion block 4 to push against a whole set of mould with nut 5.After coil winding is finished, only need dismounting nut 5 and regulate cushion block 4, owing to adopting inclined-plane 10 to engage between the adjacent internal mold section, thereby winding former can deviate from easily, is easy to separate with formed coil.

Above description is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range is referring to claim, in the situation that without prejudice to the utility model spirit, the utility model can be done any type of modification.
