Abstract
The utility model relates to a press fitting die for a transformer coil. The press fitting die comprises an upper pressing plate, a lower pressing plate and a plurality of locking parts, wherein the upper pressing plate and the lower pressing plate are arranged in parallel. A plurality of fan-shaped base plates and upper base plates are arranged below the upper pressing plate, and the lower pressing plate is provided with a plurality of lower base plates. The upper pressing plate and the lower pressing plate are respectively of a frame structure, are connected through reinforcing ribs in a welding mode and are respectively provided with corresponding connection holes. The two ends of the locking parts penetrate through the connection holes of the upper pressing plate and the connection holes of the lower pressing plate respectively to lock the upper pressing plate and the lower pressing plate. The connection holes of the upper pressing plate are closed kidney-shaped grooves, and the connection holes of the lower pressing plate are open kidney-shaped grooves. The press fitting die has the advantages that insulating paint is saved, quality control over the press fitting process is achieved, the solidification effect of the insulating paint is good and the safety performance is improved.
Description
Technical field
The utility model relates to transformer coil press mounting technical field, particularly a kind of Press-fit Mold Of Transformer Coil.
Background technology
At present flame-proof mine (KBSG) impregnated dry-type transformer series coil need be through press-fiting, be dried, dipping lacquer, the operation such as curing.General press mounting die is comprised of top board, lower platen, upper padding plate, lower bolster, suspension ring, screw rod, nut, sleeve pipe.The structure of pressing plate is to be welded by a circular steel plate (there is opening at winding protruding head place), channel-section steel, and channel-section steel end is that opening gain connects for screw rod.While using press mounting die, first on lower platen, place lower bolster, then by coil handling to lower platen, and adjust the center of coil and pressing plate and the position of backing plate, place again upper padding plate (upper padding plate need be pressed on stay), top board, finally with screw rod, nut, to coil, carry out fastening.Press-fit after end, then be dried, dipping lacquer.
There are problems in the transformer press mounting die of above prior art: a. is because of the versatility of press mounting die, and the circular steel plate opening on pressing plate is larger, goes out head region discontinuity during coil press mounting; B. the surface area of circular steel plate is large, causes the long-pending large waste insulating varnish of sticky lacquer painting; C. insulating varnish curing rear cleaning difficulty on press mounting die is large, longer because gluing the long-pending large clearance time of lacquer painting; D. the circular steel plate on pressing plate is whole plate, if quality problems appear in internal coil diameter side when press-fiting, because cannot see, cannot process in time; E., after coil upper end upper padding plate is put well, easily at top board, adjust time shift position, position, because seeing the position that cannot determine upper cushion block; F. during coil drifting dust, axially air flue blow less than; In g solidification process, the coil after dipping lacquer heats up inhomogeneous, and it is a process of ecto-entad; H. because screw rod connecting hole is opening waist type groove, there is coil and personnel's safety problem.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide and a kind ofly saves insulating varnish, press-fits a kind of Press-fit Mold Of Transformer Coil that procedure quality is controlled, insulating varnish solidification effect is better, security performance promotes.
Realize the technical solution of the utility model as follows:
A kind of Press-fit Mold Of Transformer Coil, comprise top board, lower platen, and a plurality of locking members, described top board and lower platen be arranged in parallel, top board is arranged with a plurality of fan-shaped backing plates and upper padding plate, on lower platen, be provided with a plurality of lower bolsters, top board and lower platen are frame structure and are welded to connect by reinforcement, on top board and lower platen, be respectively equipped with corresponding connecting hole, the connecting hole that passes top board and lower platen respectively by the two ends of locking member is by upper, lower platen locking, the connecting hole of described top board is the waist type groove of remaining silent, the connecting hole of lower platen is opening waist type groove.
Described fan-shaped backing plate, is frame structure, and the center of fan-shaped backing plate external margin goes out to be provided with the open slot adapting with connecting hole, as preferably, fan-shaped backing plate is positioned between top board and coil upper end, and advantage is can uniform stressed, is convenient to coil press mounting.
Described top board, lower platen, fan-shaped backing plate, upper padding plate, and lower bolster is iron.
Described top board is symmetrical semi-enclosed frame structure, and lower platen is octagon net like frame structure, and advantage is sound construction, is convenient to install, and forms the effect of full communication between the higher and lower levels.
Described locking member forms by screw rod and with the nut that screw rod matches.
Adopted above-mentioned scheme, because top board, lower platen are frame structure, sticky lacquer painting is long-pending to be reduced, and insulating varnish waste is few, and time decreased, the difficulty of cleaning press mounting die are little, and axially air flue can blow to, and heats up evenly while solidifying; In press-fiting process, can clearly see internal coil diameter side, to process in time problem; Adopt fan-shaped backing plate and upper padding plate to coordinate, can adjust flexibly and lift one's head the stressed position at place, uniform stressed while making coil press mounting; The structure change of upper and lower pressing plate screw rod connecting hole, the fail safe that has improved coil.
