Abstract
The utility model relates to a semicircle loop type magnetic core die, include well mould, go up die and lower die, nib in the semicircle loop type has been seted up at well mould center, go up the die with the cooperation of well nib is followed well mould upside inserts in the well nib, down the die with the cooperation of well nib is followed well mould downside inserts well nib, the punching press face of going up the die with the punching press interfacial of die leaves the void formation die cavity down. The utility model discloses nib in the semicircle loop type has been offered at well mould center, die and lower die in the cooperation become semicircle loop type magnetic core through the hydraulic press punching press, with annular product evolution for semicircle ring product, reduced its face area half the, not dropping into under the prerequisite of great equipment, also can produce big ring product, saved the investment of preceding current cost, the product purpose is more extensive, not only can make up to circularize the product, can finally make up into runway product etc. With product such as square collocation moreover.
Description
Technical field
The utility model relates to powder core production field, particularly relates to a kind of semi-annular powder core mould.
Background technology
Powder core can be widely used in the production of the various electronic devices and components such as communication, the energy, auto industry, household appliances, automatic door control and inductor, wave filter, transformer, inverter.Existing ring mould comprises middle mould, upper punch, undershoot, core bar, is installed on hydraulic press, forms an annular die cavity, in die cavity, insert powder by the assembly of middle mould, undershoot, core bar, and then hydraulic press drives upper punch supercharging compacting, forms annular products; This mould needs press power high, especially for large-scale ring product, need to drop into higher, costly equipment cost, and purposes is single, mould structure is complicated.
Utility model content
For the deficiencies in the prior art, the utility model aims to provide a kind of of many uses, and mould structure is simple, the semi-annular powder core mould that investment of production equipment cost is low.
Of the present utility modelly to be achieved through the following technical solutions.
A kind of semi-annular powder core mould, comprise middle mould, upper trimming die and lower punch die, described Zhong Mo center offers nib in semi-annular, described upper trimming die coordinates with described middle nib and inserts described middle nib on the upside of described middle mould, described lower punch die coordinates with described middle nib insert described middle nib on the downside of described middle mould, leaves space and form die cavity between the stamping surface of described upper trimming die and the stamping surface of described lower punch die.
Preferably, described middle mould offers the fixing threaded hole coordinated with hydraulic press.
Preferably, described upper trimming die is identical with described lower punch die.
A kind of inductance-coupled coil, comprise two and make semi-annular powder core, plural circle inductance coil by semi-annular powder core mould according to claim 1, two described semi-annular powder cores form complete circular ring type powder core, and described plural circle inductance coil is wound on described circular ring type powder core.
Preferably, also comprise two square powder cores, described square powder core coordinates with described semi-annular powder core and forms complete racetrack powder core, and described plural circle inductance coil is wound on described racetrack powder core.
Compared with prior art, the utility model has the advantages that: the utility model offers nib in semi-annular at Zhong Mo center, coordinate upper trimming die and lower punch die, strike out semi-annular powder core by hydraulic press; Annular products being developed into semicircular ring product, its face area is reduced half, not dropping under the prerequisite compared with large equipment, also can produce large circle product, eliminate cost investment in early stage; Product purpose is more extensive, can not only be combined into annular products, and can finally be combined into runway product etc. with the product mix such as square; Combination powder core available mechanism coil replaces hand winding, raises the efficiency, reduces costs.
