Description
Technical field
The present invention relates to a kind of moulding process of commutator.
Background technology
The common commutator of prior art, including phenolic moulding powder matrix and phenolic moulding powder matrix it is cylindrical make circumference arrangement change
To copper sheet, the medial surface of commutation copper sheet will set hook to be implanted into phenolic moulding powder matrix and be combined to ensure commutator with phenolic moulding powder matrix
Mechanical strength, phenolic moulding powder matrix wants solid design in addition to endoporus, and weight weight, rotator inertia are big, while heat dispersion is poor, difficult
With suitable for high-speed rotation workplace.
The content of the invention
In view of the deficiencies in the prior art, lightweight, perfect heat-dissipating can be made it is an object of the invention to provide one kind, it can answer
Commutator moulding process for high-speed rotation workplace commutator.
The present invention adopts the following technical scheme that to complete：
A kind of commutator moulding process, it is characterised in that comprise the following steps：A. the making of commutation copper sheet, screening and in mould
With phenolic moulding powder integrated injection molding, it is made including phenolic moulding powder matrix, commutation copper sheet and makees circumference arrangement in the cylindrical of phenolic moulding powder matrix
Commutator, the insulating voids between adjacent commutation copper sheet fill up phenolic moulding powder；B. commutator whole height interlude,
Phenolic moulding powder matrix is emptied to form commutator internal cavities；C. emptied in phenolic moulding powder matrix between position, adjacent commutation copper sheet
The phenolic moulding powder filled up in insulating voids is removed, and makes commutator is interior to be in a circumferential direction interlinked to the outside；D. outside the top of commutator
Circle is arranged reinforcing ring, sets reinforcing ring in the bottom cylindrical set of commutator, reinforcing ring banding is outside commutation copper sheet up and down.
By the implementation of above-mentioned technical proposal, the common commutator of prior art is made by a steps first, then empties
The interlude of phenolic moulding powder matrix, to mitigate commutator weight, so that rotator inertia during commutator high-speed rotation is able to significantly
Reduce；Phenolic moulding powder matrix interlude is removed simultaneously empties the bakelite filled up in insulating voids between the adjacent commutation copper sheet of position
Powder, makes commutator is interior to be in a circumferential direction interlinked to the outside, and to improve the heat dispersion of commutator, and passes through the setting of reinforcing ring up and down
To ensure the mechanical strength of commutator；Because rotator inertia is small, perfect heat-dissipating and with enough mechanical strengths, so this
The obtained commutator of invention can be applied to high-speed rotation workplace.

It is interlinked to the outside in circumferential direction, the top of commutator is cylindrical to be provided with upper reinforcing ring 4, and the bottom cylindrical of commutator is provided with lower reinforcing ring 6,
Reinforcing ring banding is outside commutation copper sheet 3 up and down.
A kind of commutator moulding process of the present invention, comprises the following steps：A. the making of commutation copper sheet, screening and in mould
It is interior with phenolic moulding powder integrated injection molding, be made including phenolic moulding powder matrix 1, commutation copper sheet 3 and to make circumference in the cylindrical of phenolic moulding powder matrix 1
The common commutator of the prior art of arrangement（Shown in Fig. 3）, the insulating voids between adjacent commutation copper sheet fill up phenolic moulding powder；b.
In the interlude of the whole height of commutator, phenolic moulding powder matrix 1 is emptied to form commutator internal cavities 5（Shown in Fig. 4）；c.
Being emptied the phenolic moulding powder that is filled up between position, adjacent commutation copper sheet 3 in insulating voids in phenolic moulding powder matrix 1 and be removed makes commutator
It is interior in a circumferential direction to be interlinked to the outside（Shown in Fig. 5）；D. commutator top it is cylindrical be arranged reinforcing ring 4, at the bottom of commutator
The cylindrical set in portion sets reinforcing ring 6, and commutator as shown in Figure 1, 2 is made in reinforcing ring banding outside commutation copper sheet 3, finally up and down.
