Abstract
The utility model relates to a pressing and mounting device for a transformer coil, which comprises an upper pressing plate, a lower pressing plate and a pressing and mounting shaft, wherein the transformer coil is arranged between the upper pressing plate and the lower pressing plate, the upper pressing plate is provided with a hydraulic plate driven by a hydraulic cylinder, the pressing and mounting shaft is arranged at the center of the transformer coil, the bottom end of the pressing and mounting shaft is arranged on the lower pressing plate, and the top end of the pressing and mounting shaft penetrates above the hydraulic plate. The pressing and mounting device has the following benefit that as the constant pressure is always applied to the coil in the process of drying, the height of the coil can be guaranteed to meet the product requirement, and the quality of the product can also be guaranteed.
Description
Technical field
The utility model relates to that a kind of transformer coil compresses, the press-loading apparatus when dry, relates in particular to the structure of this press-loading apparatus.
Background technology
Transformer coil need be controlled its height through super-dry, the height when making it reach its final operation.
As seen from Figure 1: coil press mounting of the prior art is by going up a lot of screw rods (102) that five equilibrium is installed at last lower platen (100,101), lower platen and hydraulic plate (103) are linked together, to go up lower platen and compress coil by tightening nut (104) on the screw rod, use the hydraulic cylinder of hydraulic pump (105) on hydraulic plate to exert pressure again and compress coil (106), then the coil band pressure and advance the drying room drying.
Adopt said structure in whole dry run, the suffered thrust of coil can not maintain a constant compression force value all the time, influences the final height of coil, thereby influences the quality of transformer.
Simultaneously, in the coil course of exerting pressure, because of the tightness of fastening nut on the screw rod inconsistent, thereby the tightening force that causes screw rod to be subjected to is unbalanced.After the fracture of a certain screw rod, and cause the stressed excessive and situation of numerous and confused fracture of all the other screw rods.On the other hand,, need all to judge whether adjunction to prolong screw rod when carrying out coil press mounting because the scope that coil height changes is greatly at every turn, thus whole press-fit the operating process time long, production efficiency is low.Many are drawn screw rod to pass three block pressur plates simultaneously to acquire a certain degree of difficulty, and the time of cost is more.
Summary of the invention
The utility model technical issues that need to address have provided a kind of press-loading apparatus of transformer coil, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: top board and lower platen; Between described top board and lower platen, settle transformer coil; On described top board, settle a hydraulic plate by the hydraulic cylinder drive; Also comprise an axle that press-fits in transformer coil central authorities; The described bottom that press-fits axle is placed on the lower platen, and the top of hydraulic plate is passed on the top that press-fits axle.
Compared with prior art, the beneficial effects of the utility model are: add constant compression force to coil in dry run, thereby the height that guarantees coil satisfies product requirement always, guarantee the quality of product.
Description of drawings
Fig. 1 is a coil press mounting structure schematic diagram in the prior art;
Fig. 2 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As seen from Figure 2: the utility model comprises: top board 1 and lower platen 2; Between described top board 1 and lower platen 2, settle transformer coil 3; On described top board 1, settle a hydraulic plate 5 by hydraulic cylinder 4 drives; Also comprise one transformer coil 3 central authorities press-fit the axle 6; The described bottom that press-fits axle 6 is placed on the lower platen 2, and the top of hydraulic plate 5 is passed on the top that press-fits axle 6;
It is fixing with lower platen 2 by a base 7 that the described bottom that press-fits axle 6 is placed on the lower platen 2;
Press-fit axle and open the draw-in groove 8 that some install snap rings on 6 length directions continuously described; The position of described draw-in groove 8 is above the hydraulic plate 5 and below top board 1; On the draw-in groove 8 that press-fits axle 6 and hydraulic plate 5 contact positions, settle a packing ring 9; Settle a snap ring 10 on the packing ring 9; Snap ring outer sleeve 11 is on hydraulic plate and be enclosed within outside snap ring and the packing ring.
The utility model uses one large diameterly to press-fit axle, to substitute the screw rod that five equilibrium is installed on pressing plate.Set up a constant hydraulic system that pressure is provided of energy, under the high situation of pressure, releasing pressure automatically, under the low situation of pressure, ftercompction automatically.
The utility model is adorned one at the lower platen center by high-strength bolt has the major diameter of base to press-fit axle, is press-fiting the draw-in groove of opening some installation snap rings on the shaft length direction; Top board and hydraulic plate center are left one can be by press-fiting the hole of axle, and the coil top hold-down is loaded onto snap ring and snap ring outer sleeve after installing.
Adopt the utility model coil to provide constant compression force, guaranteed the quality of product in drying room inner drying process.Eliminated because of nut tightness inequality, and caused the screw rod unbalance stress and damage or the problem that ruptures and the potential safety hazard brought; Avoid to regularly replace and repair the cost that increases because of screw rod;
Adopt that the utility model is whole to press-fit original operating time of operating process time ratio and descend 2/3rds, save a large amount of production times, reduce production costs.
