Abstract
An iron core winding mold core device comprises a shaft sleeve, an expander provided with an inner hole and an opening, and a clamp plate component used for tightly clamping an iron core; the shaft sleeve comprises a cylindrical basal body and a shaft part extending from the basal body; a round step surface is formed at the joint of the basal body and the shaft part; and both the expander and the clamp plate component are sleeved on the shaft part. The device is characterized in that the clamp plate component comprises an inner snap ring and an outer clamp plate; an annular step surface is formed on the inner wall of the inner snap ring, so as to divide the inside diameter of the inner snap ring into two parts: a larger part and a smaller part; one end of the expander extends into the inner snap ring and is matched with the inner snap ring on the step surface, and the other end thereof is limited on the shaft part of the shaft sleeve. Compared with the prior art, the utility model has the advantages as follows: because the expander partly extends into the inner snap ring, the expander is limited in the step surface of the inner snap ring, and the change of the inside diameter of the expander can not be changed; furthermore, the accuracy of the inside diameter of the iron core can not be ensured.
Description
Technical field
The utility model relates to a kind of coiling iron core die device, relates in particular to a kind of annular core coiling core rod device.
Background technology
Cored height is greater than the miniature toroidal iron core of 5mm, adopts rise ring and conical plug of the opening of band cone-shaped inner hole to make the mould heart.Add man-hour at coiling, the steel band end relies on the tension force of the ring that rises to come embedding tight and hook in opening part is embedded in the interlayer that rises between ring and the conical plug, makes it not slippage.The tension force of ring diminishes because the increase of service time is risen, and the ring that rises is drawn back, and causes the iron core internal diameter to become big; The different iron core internal diameter of the length size deviation of steel band embedding simultaneously also changes.Therefore the iron core internal diameter precision can't be controlled well, simultaneously, demoulding difficulty behind coiling iron core, work difficulty is big, the production cost height.
Therefore, improve the iron core internal diameter precision, to reduce labour intensity, enhance productivity be an urgent demand that iron core is produced.
The utility model content
Primary technical problem to be solved in the utility model is to provide a kind of coiling iron core die device that can accurately control the iron core internal diameter at the above-mentioned state of the art.
Another technical problem to be solved in the utility model is to provide a kind of demoulding difficulty that can reduce at the above-mentioned state of the art, improves the coiling iron core die device of demoulding efficiency.
Another technical problem to be solved in the utility model is that a kind of energy simplified structure and clamping step, the coiling iron core die device of enhancing productivity are provided at the above-mentioned state of the art.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: coiling iron core core rod device, comprise axle sleeve, the cleat assembly that rises and encircle and be used to clamp iron core with endoporus and band opening, aforesaid axle sleeve comprises a cylindrical base and the axial region that is extended by this matrix, the junction of this matrix and axial region is formed with the step cutting pattern face, and aforesaid rise the ring and cleat assembly all be sheathed on the aforementioned axial region, it is characterized in that described cleat assembly comprises interior snap ring and external splint, should make interior snap ring internal diameter be divided into big young waiter in a wineshop or an inn's part because of having an annular table terrace by interior snap ring inwall, and described ring one end that rises stretches into aforementioned interior snap ring endoporus and adapts on the step surface of interior snap ring, and the other end then is limited on the axial region of aforementioned axle sleeve by aforementioned external splint.
As improving, described axial region is arranged with elastic washer near the end of described matrix again, and the step cutting pattern face of this elastic washer one side and described axle sleeve offsets, and opposite side and described interior snap ring offset.During product stripping, can the ring that rise be taken off at an easy rate from axial region, reduce demoulding difficulty, improve demoulding efficiency by elastic washer elastic force.
Described axial region leading section at least is taper type, and the described accordingly ring endoporus that rises also is taper type.During so each taking-up iron core, just need not axle sleeve is taken off, simplified clamping step, improved operating efficiency.
As further improvement, the head of described axial region has external screw thread, and accordingly, described external splint inner hole wall has the internal thread that cooperates with aforementioned external screw thread.Simplify the structure and clamping step, enhance productivity.
Compared with prior art, advantage of the present utility model is: because the loop section that rises stretches into interior snap ring, on the annular table terrace of snap ring, can not cause the change of the ring internal diameter that rises in the ring that rises so just is limited in, thereby can not guarantee the accuracy of iron core internal diameter, so the iron core internal diameter precision height of reeling; The iron core demoulding is easy, and productive labor intensity is low; The clamping simple operations is convenient, high efficiency.

Fig. 2 dwindles decomposition assembling figure for embodiment.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Embodiment: with reference to illustrated in figures 1 and 2, the coiling iron core core rod device in the present embodiment comprises axle sleeve 1, ring 4, cleat assembly and elastic washer 2 rise.
The ring 4 that rises has endoporus and band opening 41, and cleat assembly is used to clamp iron core 5, snap ring 3 and external splint 6 in it comprises, and elastic washer 2, interior snap ring 3, rise ring 4 and external splint 6 are sheathed on the axial region 11 successively.
