Four, again in mould, the metal composite in powder is added；
Five, cold moudling；
Six, hot-forming.
Described step 2 also includes a preheating step, metal composite be driven plain whole after to metal composite heating soft
Change, in order to coiler part is absorbed in the metal composite of mold bottom.
Described coil is absorbed in the 1/4-1/3 that thickness is coil thickness of the metal composite of mold bottom.
Coil in described step one is formed by coiling, carries out subtracting foot and process after formation.
Described step 3 coil is centrally located.
Described number of molds is provided with several, and each mould includes middle mold and undershoot group, and it is defeated that mould is arranged on a circulation
Sending on band, step 2 is by the first powder filler structure and flattens mechanism and completes, and step 3 completes by mechanical hand, and step 4 passes through the
Two powder filler structures complete, and step 5 is completed by mechanism of colding pressing, and step 6 is completed by hot pressing mechanism, cold pressing mechanism and hot press
All it is provided with on structure and assembles the upper punch group of conjunction with middle mold and undershoot, the first powder filler structure, flatten mechanism, mechanical hand, second fill out powder
Mechanism, mechanism of colding pressing are arranged on endless apron side parallel, and so that the mould passed through to carry out the action process of correspondence, mould exists
After mechanism of colding pressing, undershoot group continues to follow endless apron and moves, and in middle mold and middle mold, product entrance hot pressing mechanism is carried out
Hot pressing, after hot pressing mechanism has processed, finished product takes out, and middle mold returns to re-form cooperation in the undershoot group on endless apron.
The invention has the beneficial effects as follows: the present invention adds a metal composite in powder the most in a mold by using
And compress, place into coil and position, again add the metal composite in powder and compress, then cold moudling, after heat
Molded, so realize the coherent manufacture of integrated inductor, form one layer of bottom metal complex by step 2, connect the most again
The metal composite on logical top is compressing, and the most existing manufacturing process can save the making of end core, can reduce by a matter
The generation of amount problem, reduces purchasing of production equipment, and the periphery of coil all uses unified powdery metal complex to fill out simultaneously
Fill the compacting quality in beneficially later stage, so end product quality is high.The method of the present invention is the most ingenious as can be seen here, it is possible to decrease produce
Cost, improving production efficiency, promote yield rate and end product quality simultaneously.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings:
Fig. 1 is the principle process schematic diagram of the present invention.
Detailed description of the invention
With reference to Fig. 1, the present invention is that a kind of integrated inductor manufacture method comprises the following steps:
One, preparing coil, mould, coil is formed by coiling, carries out subtracting foot and process after formation；
Two, add the metal composite in powder toward mold bottom, and metal composite is flattened；
Three, placing the coil on the metal composite of mold bottom, and position, coil is centrally located；
Four, again in mould, the metal composite in powder is added；
Five, cold moudling；
Six, hot-forming.
The present invention, by using the metal composite in powder of the interpolation one the most in a mold and compressing, places into coil also
Location, again adds the metal composite in powder and compresses, then cold moudling, the most hot-forming, so realizes one
The coherent manufacture of formula inductance, forms one layer of bottom metal complex by step 2, connects the metal composite on top the most again
Compressing, the most existing manufacturing process can save the making of end core, can reduce the generation of quality problems, reduces raw
Purchasing of product equipment, the periphery of coil all uses unified powdery metal complex to fill the compacting matter being beneficial to the later stage simultaneously
Amount, so end product quality is high.The method of the present invention is the most ingenious as can be seen here, it is possible to decrease production cost, improving production efficiency,
Promote yield rate and end product quality simultaneously.
Step 2 also includes a preheating step, metal composite be driven plain whole after to metal composite thermoplastic, with
Just in coiler part is absorbed in the metal composite of mold bottom；It is coil that coil is absorbed in the thickness of the metal composite of mold bottom
The 1/4-1/3 of thickness.So can easily coil be positioned.
As it can be seen, described number of molds is provided with several, each mould includes middle mold and undershoot group, and mould is arranged on
On one endless apron, step 2 is completed by the first powder filler structure and pressing mechanism, and step 3 is completed by mechanical hand, step
Four are completed by the second powder filler structure, and step 5 is completed by mechanism of colding pressing, and step 6 is completed by hot pressing mechanism, mechanism of colding pressing
And be all provided with on hot pressing mechanism and assemble the upper punch group of conjunction with middle mold and undershoot, the first powder filler structure, flatten mechanism, mechanical hand,
Second powder filler structure, mechanism of colding pressing are arranged on endless apron side parallel, to carry out the mould passed through at the action of correspondence
Reason, mould is after mechanism of colding pressing, and undershoot group continues to follow endless apron and moves, and in middle mold and middle mold, product enters hot pressing
Mechanism carries out hot pressing, and after hot pressing mechanism has processed, finished product takes out, and middle mold returns in the undershoot group on endless apron again
Formed and coordinate.So pipeline system manufacture, can significantly improving production efficiency, concrete action is as follows, and mould moves to
Complete to fill out powder action time at first powder filler structure, then move to flatten mechanism and complete the pressing of the metal composite to bottom, then
Move to, at mechanical hand, coil is put into mould, move again to the and complete second time time at powder filler structure and fill out powder action, so
After the mechanism that moves to cold pressing complete to cold pressing, undershoot group continues to follow endless apron and moves, and in middle mold and middle mold, product enters heat
Press mechanism carries out hot pressing, and after hot pressing mechanism has processed, finished product takes out, and middle mold returns in the undershoot group on endless apron, weight
Being newly formed cooperation, work efficiency is the highest.
Above-described embodiment is the preferred version of the present invention, and the present invention also can have other embodiments.The technology of this area
Personnel also can make equivalent variations or replacement on the premise of spirit of the present invention, and modification or the replacement of these equivalents are all wrapped
It is contained in the scope set by the application claim.
