Description

One kind opening rewinding material chip turntable

Technical field

The present invention relates to one kind opening rewinding material chip turntable, the assembling for the opening Wound iron-core transformer that is particularly suitable for use in.

Background technology

At present, transformer core is by the silicon steel sheet shear forming that thickness is 0.23~0.35mm, then successively closed assembly piecewise, Silicon steel sheet is a kind of very capable magnetisable material of magnetic conduction in itself, in hot-wire coil, can produce larger magnetic induction intensity.

Traditional transformer iron core dresses up multistage circle or oval stem by more level width silicon steel sheet stacks, covers and forms transformation with coil Device device body.Multiple silicon steel sheet stack additions form per one-level thickness, and per one-level by five kinds of piece shapes, seam at least six, cause No-load current and open circuit loss are higher, thus urgently improve the form of iron core.

Iron core after improvement uses opening rewinding material, and the form unshakable in one's determination is shown in Fig. 1 and Fig. 2, including housing（11）And inside casing （12）, its seam is shown in Fig. 3, including upper yoke（31）, stem（32）With lower yoke（33）.Because every piece only has two seams, so as to Greatly reduce no-load current and open circuit loss.But above-mentioned opening rewinding material is bending and molding, and traditional stacking technique without This iron core of method closed assembly, so need to develop supporting closed assembly equipment.

The content of the invention

For above-mentioned existing technical problem, the present invention provides a kind of opening rewinding material chip turntable, to solve to be open The problem of rewinding material closed assembly shaping.

To achieve the above object, the present invention provides a kind of opening rewinding material chip turntable, including the support positioned at bottom, By the swivel slide that rotary shaft is rack-mount, two centre-to-centre spacing being arranged on side by side by slide fit sympodium on swivel slide Slide plate is positioned, and both spacing can be adjusted by positive left-hand thread screw mandrel, and is separately mounted to corresponding centre-to-centre spacing positioning slide plate top Two groups of inside casing locating pieces in portion；Every group of described inside casing locating piece includes two locating pieces, and can be adjusted by positive left-hand thread screw mandrel Both spacing.

Further, the width of every group of described inside casing locating piece when in use is consistent with window width unshakable in one's determination, can pass through After positive left-hand thread screw mandrel regulation, then start processing work.

Further, the centre-to-centre spacing of two described centre-to-centre spacing positioning slide plate when in use is consistent with centre-to-centre spacing unshakable in one's determination, can After being adjusted by positive left-hand thread screw mandrel, then start processing work.

To sum up, the present invention is devised out for transformer core using the bending molding process needed for opening rewinding material, spy Mouthful rewinding material chip turntable, to realize iron core is different from traditional stacking technique, solves processing problem, raising Operating efficiency.The iron core that processes can greatly reduce no-load current and open circuit loss simultaneously, improve transformer into The electric property of product.

Embodiment

The invention will be further described below in conjunction with the accompanying drawings.

As shown in Figure 4 and Figure 5, the present invention is including the support 44 positioned at bottom, the swivel slide 43 on support 44, Two centre-to-centre spacing positioning slide plate 42 on swivel slide 43, and installed in the top of each centre-to-centre spacing positioning slide plate 42 One group of inside casing locating piece 41.

Wherein：After swivel slide 43 is arranged on support 44 by rotary shaft 51 at its center, rotary shaft can be surrounded 51 rotations, as shown in Figure 8；Two centre-to-centre spacing positioning slide plates 42 are arranged on swivel slide 43 side by side by slide fit sympodium, in advance By both spacing of positive left-hand thread screw mandrel regulation, with ensure when in use both centre-to-centre spacing it is consistent with centre-to-centre spacing unshakable in one's determination, conveniently Turn to match somebody with somebody, as shown in Figure 6；In two groups of inside casing locating pieces 41, every group includes two locating pieces, and is adjusted in advance by positive left-hand thread screw mandrel Both spacing of section, to ensure that both width are consistent with window width unshakable in one's determination when in use, as shown in Figure 6.

During implementation, as depicted in figs. 1 and 2, during opening rewinding material processing, shearing bending inside casing 12 first, so by multiple Silicon steel sheet is first successively piled up on the inside casing locating piece 41 regulated；After two inside casings 12 are piled up, then carry out outside shearing bending Frame 11, multiple silicon steel sheets are successively piled up outside two small inside casings 12, the latter half unshakable in one's determination of handstand is formed, as shown in Fig. 6 and Fig. 7 The stem 32 of lower yoke 33 and three unshakable in one's determination.

Then, by three colligations of stem 32 of iron core, fix with the centre-to-centre spacing positioning slide plate 42 regulated, slided using rotation Plate 43, which is rotated to normotopia, rotary course, as shown in Figure 8, then to be installed the annexes such as folder, is finally removed from turntable of the present invention, in case Mounting coil.

Then, the shearing code of the rewinding material upper yoke 31 that is open part folds method with the latter half unshakable in one's determination, and silicon steel sheet is first Successively pile up on the inside casing locating piece 41 regulated, first shearing bending inside casing 12, then carry out the grade one of shearing bending housing 11 Sequence of maneuvers.

Using this turntable, closed assembly shaping conveniently can be carried out to opening rewinding material, improve production efficiency, dropped Low manufacturing cost, is especially suitable for promoting the use of on a large scale.
