Description
Technical field
The present invention relates to a kind of plastic shaping processing method, relate in particular to a kind of processing method of commutator strengthening ring, belong to plastic working method technical field in the operation Department of Transportation.
Background technology
Be applied in that commutator on the motor is general all to form by commutator segment and mica sheet are spaced, its bulk strength is relatively poor, and is yielding in the use, is difficult to bear the huge centrifugal force that is produced under the motor high-speed and high-temperature condition, the scrappage height.Produced a kind of reinforcing ring that is applied on the commutator, this reinforcing ring can improve the commutator quality and prolong the useful life of commutator for this reason.
At first, use the reinforcing ring of steel, because poor insulativity, limited its use, generally use plastic reinforcing ring now, plastic reinforcing ring generally all passes through preparation resin glue, impregnation, bakes and banks up with earth, adorns this several steps of mould, mould unloading and subsequent treatment, and the selection of raw material and the control of processing conditions are very big to the quality influence of product.With reference to Chinese invention patent: ZL02112020.X, a kind of " manufacture method of high-strength stiffening ring of commutator " (Granted publication number: CN1238932C) is disclosed, this invention with F51 epoxy resin and 304 curing agent as resin glue, be used for impregnation with E27/3 alkali-free glass yarn, as mould, this mould can unclamp with flake rod.Same applicant has applied for that again the another one application number is 200510023210.3 Chinese invention patent application, its denomination of invention is " a kind of manufacture method of strengthening ring for commutator " (publication number: CN1640652A), this application is a resin glue with F46 epoxy resin and 504 curing agent, and, mould adopts rod iron, and cutting is finished then.Tensile strength is 600～700MPa in the reinforcing ring practical application that the use said method makes, high temperature resistant level can only maintain 200 ℃, the high temperature resistant level of product is low to be easy to ooze out from the commutator segment of commutator and mica sheet, forms " strike-through " phenomenon, influences the running of motor.
Because tensile strength and high temperature resistant level are undesirable, Chinese invention patent application for this reason: 200610008263.2, " a kind of manufacture method of high-temperature-resisting reinforced ring of commutator and dedicated manufacturing equipment " (publication number: CN1819369A) is disclosed, this application with F51 epoxy resin and 504 curing agent and titanium dioxide as resin glue, with SC8-960 alkali-free glass fibre yarn as impregnation, and bake and bank up with earth in conjunction with twice gradient increased temperature mode, there is following deficiency in this method: at first adopt and bake and bank up with earth for twice, accelerated product aging, shorten the useful life of product, increased the waste of the material and the energy; Secondly, cause damaged products easily owing to adopt the punch press punching to be the semi-finished product reinforcing ring, increase stress, tensile strength reduces.Same in addition applicant is in the Chinese invention patent application: 200410032030.7 (publication numbers: disclose a kind of " manufacture method of high-temperature-resisting reinforced ring of commutator " CN1585212A), be impregnation with EC8-27 * 1 * 3 alkali-free glass fibre yarn in this application, above-mentioned manufacture method makes the tensile strength of product and high temperature resistant level be improved, but its increase rate is limited, and, because " strike-through " that the restriction of high temperature resistant level causes, and the scrappage of finished product is higher.Again with reference to the Chinese invention patent application: 200610050356.1, " a kind of manufacture method of strengthening ring for commutator " (publication number: CN1585212A) is disclosed, use phenolic resins as curing agent in this application, in technology, adopt simultaneously forced air drying technology and winding technology in advance, improved the stability of product, reduced scrappage, but this product practical application tensile strength can only reach 1000Mpa, also need further to improve.
