Abstract
The invention discloses a production method of a low-frequency transformer skeleton with low production cost, high production efficiency and high strength, which comprises the following steps: inserting a metal wire into a connecting pin die; cutting the metal wire to the required length as a connecting pin; energizing and heating the connecting pin inserted into the connecting pin die for softening; pressing one end of the connecting pin into a T-shaped stitch by a hydraulic cylinder; and combing the connecting pin die and the connecting pin with a skeleton die and forming as a whole by injection so as to integrate the connecting pin and a skeleton body. The production method disclosed by the invention effectively enhances the production efficiency and reduces the production cost, the pressed novel T-shaped stitch and the other part of the skeleton are injected together as a whole, the connection is firm, and higher connection strength can be ensured. The production method can be applied in the production field of transformers.
Description
Technical field
The present invention relates to a kind of manufacture method of low-frequency transformer skeleton.
Background technology
Transformer framework, when producing, needs default wiring pin, and this wiring pin is for connecting the line end with stationary transformer winding.As shown in Figure 4, mostly adopt the production technology of the wiring pin of " T " font in existing transformer framework, it need to first be fixed on the wiring pin of " T " font in mould when producing, then is integrated with the injection mo(u)lding of skeleton main body.The fixing comparatively complexity of the wiring pin of existing " T " font in framework forming die, and need to carry out the pre-buried contact pin of craft.This complex operation, operating efficiency is low, has increased thus the input of manpower and materials, has greatly increased production cost.In addition, adopt artificial pre-buried mode to be difficult to guarantee that wiring pin is in the intrinsic position consistency of skeleton, be difficult to ensure that wiring pin has higher intensity.
In sum, there is the technological deficiency that cost is high, production efficiency is low, intensity is lower in the transformer framework manufacture craft of existing band " T " font wiring pin.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, and a kind of manufacture method that can guarantee the low-frequency transformer skeleton that cost of manufacture is low, production efficiency is high, frame strength is higher is provided.
The technical solution adopted in the present invention is: the present invention is a kind of manufacture method of low-frequency transformer skeleton, described low-frequency transformer skeleton is comprised of skeleton body and wiring pin and is one-body molded by mould, described mould comprises wiring pin mould and skeleton die, it is characterized in that, the method comprises the following steps:
A, wiring pin are made: inserting in described wiring pin mould for making the metal wire of wiring pin, by the length of wiring pin, make requirement and block metal wire, to described wiring pin mould energising, the metal wire that heating is truncated makes it softening, then one end of the metal wire being softened is pressed into T-shaped stitch, obtains wiring pin;
B, mould combination: the wiring pin mould with wiring pin and described skeleton die are combined, and wherein, the T-shaped stitch of described wiring pin is positioned at the cavity of described skeleton die;
C, integrated injection molding: in the assembling die of processing through step b, inject sizing material, make described wiring pin and this body by integral forming of transformer framework, obtain low-frequency transformer skeleton.
In described step a, the wiring pin number required according to low-frequency transformer skeleton inserts the metal wire of similar number in the corresponding lumen pore of described wiring pin mould simultaneously, arranges and clamps.
The invention has the beneficial effects as follows: because the present invention adopts wiring pin mould and the integrated T-shaped wiring pin of skeleton die, do not need to carry out the pre-buried contact pin of craft, so can effectively simplify production process, reduce the input of manpower and materials, when producing, metal wire is inserted in wiring pin mould and blocked by wiring pin Len req, compress again compacting after stitch heating is formed to T-shaped stitch, finally together with described wiring pin mould, be combined with skeleton die, integrated injection molding, effectively improved production efficiency, reduce T-shaped stitch and skeleton body in production cost and the present invention and be together injected into integral body, and described wiring pin is in compacted process, the circle diameter at compacted position is less than the circle diameter of other parts wiring pin, this structure is in injection moulding process, make to connect more firm, can ensure that wiring pin has higher bonding strength.

Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, the present invention is a kind of manufacture method of low-frequency transformer skeleton, described low-frequency transformer skeleton is comprised of skeleton body 1 and wiring pin 2 and is one-body molded by mould, and described mould comprises wiring pin mould and skeleton die, and the method comprises the following steps:
A, wiring pin are made: inserting in described wiring pin mould for making the metal wire of wiring pin, by the length of wiring pin, make requirement and block metal wire, to described wiring pin mould energising, the metal wire that heating is truncated makes it softening, then one end of the metal wire being softened is pressed into T-shaped stitch, obtains wiring pin;
B, mould combination: the described wiring pin mould with wiring pin and described skeleton die are combined, and wherein, the T-shaped stitch of described wiring pin is positioned at the cavity of described skeleton die;
C, integrated injection molding: in the assembling die of processing through step b, inject sizing material, make described wiring pin and this body by integral forming of transformer framework, obtain low-frequency transformer skeleton.
In described step a, the wiring pin number required according to low-frequency transformer skeleton inserts the metal wire of similar number in the corresponding lumen pore of described wiring pin mould simultaneously, arranges and clamps.
As shown in Figure 5, in described step a, metal wire discharging volume 3, after feed lead rail 4 and twin pressure roller 5 compactings, enter in wiring pin mould 6, in described wiring pin mould 6, the back segment of the endoporus that wiring pin 2 is passed is set to counterbore 7, and after the 2 energising thermoplastics of described wiring pin, the hydraulic cylinder being driven by hydraulic electric motor 98 by periphery presses to wiring pin 2 in counterbore 7 and forms T-shaped wiring stitch.Blanking cutter 10 cuts off metal wire.In described step a, described wiring pin is in compacted process, the circle diameter at compacted position is less than the circle diameter of other parts wiring pin, this structure is in injection moulding process, mould-injection is clamped on the position that circle diameter is little after moulding, make connection more firm, can ensure that wiring pin has higher bonding strength.
The present invention can be applicable to transformer framework and makes field.
