Application number be 200410001739.0 Chinese patent disclose a kind of copper roll type manufacture method of commutator, comprise wire rod rolling, drawing, annealing successively, and the operation such as punching, compacting, solidification, fraising, turning, groove milling, sanding, polishing, described punching operation is the commutation blade group wire rod punching of having annealed circularized.But this method production procedure needs to be optimized further, and quality stability, stock utilization, the accuracy of manufacture etc. have to be strengthened.
Summary of the invention
The present invention mainly provides a kind of planar all-plastic commutator processing method, and its machine-shaping is simple, and operation is less, and production procedure is short, take production equipment few, stock utilization is high, and precision is easy to control, constant product quality is good, alleviates labour intensity, improves production efficiency.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: it comprises the following steps: (1), punching commutator segment and injection-moulded plastic shell; (2), screening: the commutator segment that punching is good is inserted in described plastic housing, commutator segment is arranged in plastic housing; (3), die-filling: the described plastic housing through screening is put into mould; (4), matched moulds compacting: described mould is put into press, adds the compacting of appropriate phenolic moulding powder matched moulds; (5), de-plastic housing.
As preferably, the described mould in described step 3 before die-filling through the pre-heat treatment.
As preferably, the described mould in described step 3 is provided with some cavitys for the compacting of planar all-plastic commutator matched moulds.Once can carry out the matched moulds compacting of several commutator like this, thus substantially increase production efficiency.
As preferably, described step 5 is that the product formed processing through step 4 takes out, and is then separated from described product by plastic housing.
As preferably, described plastic housing comprises tray body, is provided with through hole in the middle part of tray body, and described through hole periphery is provided with the first support anchor ring, described first supports anchor ring periphery is provided with the second support anchor ring, and described first support anchor ring is provided with some radially spaced ribs.Rib of the present invention instead of traditional mica sheet, thus arrangement mica sheet while noting be used in arrangement commutator segment, decrease the complexity of screening, further increase commutator production efficiency, and at plastic housing after the separation of products after matched moulds compacting, rib can leave indenture and form lower cutting on product, save the operation of the lower cutting of processing, further make the precision of lower cutting controlled, ensure that the stability of commutator crudy.
As preferably, described second supports anchor ring supports anchor ring higher than first.
As preferably, described second supports anchor ring periphery is provided with ring-type convex tendon.
As preferably, described rib is strip convex tendon.
The beneficial effect that the present invention brings is, the present invention adopts plastic housing to carry out auxiliary screening, matched moulds compacting, its machine-shaping is simple, and operation is less, and production procedure is short, take production equipment few, stock utilization is high, and precision is easy to control, and constant product quality is good, alleviate labour intensity, improve production efficiency.
