Gyroscopic couple device coil molding mould and forming method
Technical field
The invention belongs to manufacturing technology, relate to a kind of gyroscopic couple device coil molding mould and forming method.
Background technology
Torquer is one of critical component of flexible gyroscope (being called for short gyro to call in the following text), and gyro has strict requirement to torquer coil dimension and shape, and this processing to the torquer coil has proposed higher accuracy requirement.
The torquer coil add work point coiling and moulding, differences in shape is greatly that the winding deformation amount is big after shape behind the coil winding and the moulding, controls the bad phenomenon that is prone to loose wire after the moulding, broken string.Traditional method winding process is: coiling is simultaneously to the enameled wire brush coating, and coiling is toasted coil after accomplishing, last moulding.Advantage is that forming process is difficult for broken string (mainly due to moulding time enameled wire interlayer do not have bounding force), and shortcoming is that product line loop-shaped and dimensional uniformity difference cause scrappage, and normal condition has 50% coil to scrap can not to use; Coil winding efficient is low, stoving time is long, and environment is polluted.
For raising the efficiency and end product quality, adopt automatic coil winding machine coiling torquer coil.The torquer coil efficiency of automatic coil winding machine coiling improves than traditional-handwork coiling efficient greatly; But the qualification rate at forming process product line loop-shaped and dimensional uniformity is low; Its reason is that coiling process enameled wire interlayer has formed the self-adhesion bounding force; Plastic yield is bigger during coil molding, the phenomenon of loose wire broken string can occur, nearly 40% scrappage.
Summary of the invention
The objective of the invention is to propose a kind of moulding qualification rate high gyroscopic couple device coil molding mould and forming method.Technical solution of the present invention is to utilize the mould of being with temperature control equipment to guarantee the physical dimension of gyroscopic couple device coil.Mould comprises base, heater strip, moulding briquetting, register pin, press moulded bodies, bearing, location briquetting, coil, bed die, thermopair, lead-in wire groove, and heater strip is wrapped on the bed die, on register pin is installed in the moulding briquetting in the press moulded bodies chute; Bed die is fixed on the base; The bottom surface of press moulded bodies has the lead-in wire groove, and base is installed in the bottom surface of press moulded bodies, and the location briquetting is installed in the chute of bearing; Bearing be installed in press moulded bodies above, thermopair is installed on the bed die.
The forming method of said mould molding gyroscopic couple device coil is,
(1) mould is heated to 120 ℃ ± 5 ℃ and insulation;
(2), the torquer coil that coiling is good puts into mould, makes coil heats to 120 ℃ ± 5 ℃ and insulation;
(3), start the positioning limit switching cylinder, the positioning limit pressure head on the spacing cylinder of triggered location is located mould for briquetting and is added and be pressed in by on the formed coil, source of the gas air pressure 5 ± 0.5 MPas are waited for 10sec~20sec;
(4), start the forming cylinder switch, triggers four forming cylinders and four moulding briquettings of mould are added is pressed in by on around the formed coil, source of the gas air pressure 5 ± 0.5 MPas, wait 10sec~20sec:
(5), earlier close the moulding switching cylinder, four forming cylinders are return initial position; Close the positioning limit switching cylinder again, the positioning limit cylinder is return initial position, the torquer coil after the taking-up moulding.
Advantage that the present invention has and beneficial effect; The invention solves self-binding enamel wire coil molding process and the situation of loose wire, short-term very easily occurs; Adopt the mould of being with temperature control system to solve the defective of coil molding process, the product qualified rate that has guaranteed the torquer coil is greater than 98%.In addition, the loop product of utilizing the present invention to produce, the outward appearance high conformity, this is useful to improving the gyro overall performance.Solved the moulding problem that multiturn is counted the machine coiling, for the moulding of coil from now on provides the solution thinking.
