Abstract

Provided is a die special for a rectangular amporphous-nanocrystalline current transformer iron core. Two inner framework blocks are flexibly connected with each other through a positive and negative screw rod. A rectangular framework with a boundary dimension bigger than that of a rectangular mutual inductor is arranged on the periphery of the two inner framework blocks. Screws are added in the middle portion of trisected points on each side of the framework to fix. Chamferings with a radius of 2 millimeters are arranged on four corners of the two inner framework blocks. Four irony dab-boards with the thickness of 2.5 millimeters same with the size of the product are arranged on four sides of the rectangular framework. The rectangular amporphous-nanocrystalline current transformer iron core exclusive-using die is characterized in that the rectangular amporphous-nanocrystalline current transformer iron core is easy to mould, simple in process and low in device investment, waste of strip during the manufacturing process of rectangular irony core is reduced and production efficiency is improved and product appearance is improved and performance is improved.

Description

Rectangle amorphous nano-crystalline current transformer core particular manufacturing craft
Technical field
The utility model relates to a kind of rectangle amorphous nano-crystalline current transformer core particular manufacturing craft.
Background technology
Power current transformer uses traditional soft magnetism material silicon steel disc always, yet along with the amorphous soft magnetic material production technology is constantly ripe, production cost descends, and especially non-crystaline amorphous metal and amorphous nano peritectic alloy have a series of premium properties such as high magnetic strength, high magnetic permeability, high saturated magnetic induction, low-loss and good thermal stability and constantly capture the sector.National grid requires progressively also that various magnetic elements will use non-crystaline amorphous metal and amorphous nano-crystalline alloy material in the electrical network.
Amorphous band also has its weakness, band thin (approximately 30um), and fragility large (particularly after the annealing) is difficult for being wound into rectangle, so that amorphous nano-crystalline power current mutual inductance production cost high-quality is poor.This mould has solved this problem well.
Summary of the invention
The utility model provides a kind of waste that has reduced band in the rectangle iron core preparation process, has improved the rectangle amorphous nano-crystalline current transformer core particular manufacturing craft of production efficiency.
The utility model is achieved by the following technical solution: a kind of rectangle amorphous nano-crystalline current transformer core particular manufacturing craft, its technical characteristics is that it is by movable fixing by a positive and negative screw rod in the middle of two inside casing pieces, two inside casing pieces are arranged with size outward than the large rectangle frame of rectangle instrument transformer product design size, and fix at each three equal parts point middle part, limit adding screw of framework;
It is the chamfering of 2mm that four jiaos of described two inside casing pieces have radius;
It is 2.5mm irony baffle plate with the measure-alike thickness of product housing that four limits of described rectangle frame are respectively established four.
The utility model beneficial effect is: 1 so that rectangle amorphous nano-crystalline electric power mutual-inductor iron core is easy to moulding, and technique is simple, and equipment investment is few; 2, reduce the waste of band in the rectangle iron core preparation process, improved production efficiency; 3, improve the product appearance pattern, improved its performance.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
As shown in Figure 1, this rectangle amorphous nano-crystalline current transformer core particular manufacturing craft, by fixing by positive and negative screw rod 2 activities in the middle of two inside casing pieces 1, the 1-1, two inside casing pieces are arranged with size outward than the large rectangle frame 3 of rectangle instrument transformer product design size, and fixing at each three equal parts point middle part, limit adding screw 4 of framework; It is the chamfering of 2mm that four jiaos of two inside casing pieces have radius; It is 2.5mm irony baffle plate with the measure-alike thickness of product housing that four limits of rectangle frame are respectively established four.
The mould preparation process is: prepare two inside casing pieces according to rectangle instrument transformer product inside casing size with steel first, do the chamfering that radius is 2mm for four jiaos, add a positive and negative screw rod so that two inner frames can freely outwards mobilely also can be stablized in the middle of two inside casing pieces; Do again a size than the rectangle frame of rectangle instrument transformer product design size large (highly identical), and add screw (size is decided according to the product height, being fixed as) in each three equal parts point middle part, limit of framework; Do at last four with the about 2.5mm iron plate of the measure-alike thickness of product housing; Above all thickness of steel product are selected about 560 ℃ of lower indeformable being as the criterion of temperature.
The mould using method is: calculate diameter of a circle under the same circumference according to instrument transformer product inside casing size, first with strip coil coiled annular, and put it in the mould rectangle housing; Through the positive and negative screw rod of conciliation two inside casings are moved to minimum distance soon again and put into circular magnetic core, make the iron core inner chamber reach the product cavity size at the positive and negative screw rod of slow circumvolve; Around iron core, put the iron block of corresponding size well, thereby screw extruding iron block compresses iron core around the last uniformly rotation outside framework, and prevent that the annealing process iron core is loose.
