Abstract
The utility model discloses a binding element-free amorphous alloy powder annular magnetic core which comprises an annular box and an annular box cover, wherein amorphous alloy powder is arranged in the annular box. After simultaneously subjected to foreign force action, the annular box cover and the amorphous alloy powder are fixed into a whole annular magnetic core. The binding element-free amorphous alloy powder annular magnetic core solves the problems that a traditional magnetic core is low in filling coefficient of amorphous alloy powder, and poor in electromagnetic property.
Description
Technical field
The utility model relates to the non-crystaline amorphous metal magnetic core and makes the field, relates to specifically a kind of amorphous powdered alloy toroidal core of adhesive-free.
Background technology
Amorphous alloy material has excellent combination property, such as high strength, high rigidity, wear-resisting, anti-corrosion, high resistivity, high magnetic conduction, low-loss.Because of its excellent performance, developed rapidly in recent years, people competitively develop the amorphous powder magnetic core, and amorphous powder is put into mould, add simultaneously bonding agent, form the amorphous powder magnetic core after pressurization.Because amorphous powder is the amorphous powder magnetic core that the effect of dependence bonding agent makes, this has just reduced the activity coefficient of amorphous powder greatly, thereby reduce the electromagnetic performance of magnetic core, so that the electromagnetic performance of the excellence that non-crystaline amorphous metal originally possesses can not be brought into play, particularly in the field of making anti-direct current non-crystaline amorphous metal magnetic core, the impact of amorphous powder activity coefficient is more important.
Summary of the invention
In view of above-mentioned present situation, the utility model provides a kind of amorphous powdered alloy toroidal core of adhesive-free, not only improved the activity coefficient of amorphous powdered alloy, also so that the electromagnetic performance of the excellence that non-crystaline amorphous metal possesses give full play of, particularly in the field of making anti-direct current non-crystaline amorphous metal magnetic core, the amorphous powdered alloy magnetic core of this adhesive-free is more applicable.
Technical solution of the present utility model realizes by following measures.A kind of amorphous powdered alloy toroidal core of adhesive-free, comprise ring box, in described ring box, amorphous powdered alloy is housed, also include an annular lid, after described annular lid and amorphous powdered alloy were subject to External Force Acting simultaneously, this annular lid and ring box were fixed into the toroidal core of an integral body.
During this was novel, related ring box comprised double-deck circular cylinder, and wherein an end has an annular back cover, and the other end is the open end.
During this is novel, be connected to welding between related ring box and the annular lid.
Further, related ring box, annular lid are circles, or oval.
This novel described ring box, annular lid are that stainless steel material is made.
The good effect that the utlity model has is: because having adopted the molding mode of adhesive-free amorphous powdered alloy magnetic core; along with covering, ring stainless steel is pressed into together in the stainless steel annular box by the Powdered non-crystaline amorphous metal of packing in the stainless steel annular box; on amorphous powdered alloy, be pressed into stainless steel annular lid; therefore before removing pressure; implement welding, magnetic core becomes as a whole under the protection of ring box and annular lid.Solved the poor problem of activity coefficient electromagnetic performance low, magnetic core of the amorphous powder of traditional magnetic core.
Description of drawings
Fig. 1 is this novel schematic diagram.
Embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
The amorphous powdered alloy toroidal core of adhesive-free as shown in Figure 1, comprise ring box 1, the ring box 1 of present embodiment adopts the pair of lamina circular cylinder, wherein an end has an annular back cover, the other end is the open end, also include an annular lid 2, this annular lid 2 is installed in the open end of ring box 1.For finishing the amorphous powdered alloy toroidal core of described adhesive-free, and amorphous powdered alloy 3 is housed in ring box 1, be pressed into described annular lid 2 by external force, make amorphous powder 3 and ring box 1 and annular lid 2 close contacts, before removing external force, implement welding, guaranteed that annular lid 2, ring box 1 and amorphous powdered alloy 3 are fixed into the toroidal core of an integral body.
In the present embodiment, except described ring box 1,2 one circles of annular lid, can also select ellipse.
The described ring box 1 of present embodiment, annular lid 2 are that stainless steel material is made.
Implementing this novel key is: adopted and formed an activity coefficient height, toroidal core that electromagnetic performance is good between stainless ring box 1 and annular lid 2 and the amorphous powdered alloy.
