Description

R type transformer core trimmer
Technical field
The utility model relates to a kind of R type transformer core trimmer.
Background technology
At present, the core construction of widely used power transformer mostly is stacked, in the closed magnetic circuit that the iron core of this structure forms, has air-gap to exist, thereby is directed at the increase of magnetic resistance and leakage field.And the transformer core of this structure is many with material, loss is large, reactive power consumption is large, thereby reduce power factor, increased line loss.Energy saving and environment friendly product is just actively promoted the use of in China and even the whole world now, and R type transformer core has advantages of that open circuit loss is little, no-load current is little and noise is low, compared with laminated core, open circuit loss can decline 10 ~ 25%, no-load current can decline 50 ~ 70%, therefore, R type transformer is just being widely used in power system.But R type transformer core comparison is special, it is by two inside casings of the first coiling of R type transformer core up-coiler by silicon steel sheet band, again two inside casings are combined to coiling housing, form a three phase three limb core structure, owing to can producing internal stress in silicon steel sheet in R type transformer core winding process, must be through the high temperature anneal, clamp processing and just must carry out shaping to R type transformer core before annealing, to guarantee R type transformer core every size conforms drawing technical requirement after annealing.At present, R type transformer core generally adopts the method for the manual shaping of screw-pressing, and every size of the transformer core of not only time and effort consuming of shaping, and R type in this way is also difficult to guarantee.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of labour intensity that can reduce workman, enhances productivity and can guarantee the R type transformer core trimmer of R type transformer core size.
The technical solution adopted in the utility model is: comprise base plate, three high-voltage oil cylinders, support plate, hydraulic power unit and hydraulic control boxs; Described three high-voltage oil cylinders and support plate are fixedly mounted on base plate, and support plate is perpendicular to base plate; Two high-voltage oil cylinders in three high-voltage oil cylinders are oppositely arranged, and the center line of two high-voltage oil cylinders is parallel to support plate; Another high-voltage oil cylinder and support plate are oppositely arranged, and the center line of this high-voltage oil cylinder is perpendicular to support plate, and the center line of three high-voltage oil cylinders is positioned at same plane; Three high-voltage oil cylinders are connected with hydraulic power unit respectively, and hydraulic power unit is connected with hydraulic control box.
In above-mentioned R type transformer core trimmer, described base plate is octagon.
Compared with prior art, the beneficial effects of the utility model are: the utility model clamps by hydraulic control box control high-voltage oil cylinder, can realize in the short period of time shaping to R type transformer core, clamp one-time-reach-place, not only save time but also laborsaving than artificial shaping, greatly reduce workman's labour intensity; The utility model is even and big or small adjustable to the thrust of R type transformer core all directions, at utmost guarantee shaping quality, after making the shaping of R type transformer core, every size meets drawing technical requirement more, also can not produce as manual shaping and easily make R type transformer core be inclined to the phenomenon of parallelogram; That the utility model also has advantages of is simple in structure, flexible movements are reliable and operating efficiency is high.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is the clamping schematic diagram of R type transformer core on the utility model.
specific implementation method
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, the utility model comprises three high-voltage oil cylinders (being respectively the first high-voltage oil cylinder 1, the second high-voltage oil cylinder 3 and third high compressing cylinder 4), octagon base plate 2, support plate 5, hydraulic control box 6 and hydraulic power unit 7.Three high-voltage oil cylinders and support plate 5 are fixedly mounted on base plate 2; Support plate 5 is perpendicular to base plate 2.The second described high-voltage oil cylinder 3 is oppositely arranged with third high compressing cylinder 4, and the second high-voltage oil cylinder 3 is parallel to support plate 5 with the center line of third high compressing cylinder 4.The first described high-voltage oil cylinder 1 is oppositely arranged with support plate 5, and the center line of the first high-voltage oil cylinder 1 is positioned in a plane perpendicular to the center line of support plate 5, the first high-voltage oil cylinders 1, the second high-voltage oil cylinder 3 and third high compressing cylinder 4.Support plate 5 is arranged on hydraulic power unit 7; Three high-voltage oil cylinders are connected with hydraulic power unit 7 respectively; Hydraulic power unit 7 is connected with hydraulic control box 6.
When assembling the utility model, first hydraulic power unit 7 has been assembled on ground, and by fixed with foundation bolt and ground to outer cover and frame, frame must have enough intensity, to can bear with upper-part and be shaped R type transformer core weight.Then support plate 5 and hydraulic power unit housing are fixed together, next octagon base plate 2 and support plate 5 are linked together, must guarantee that base plate is mutually vertical with support plate, for the R type transformer core 8 that makes to be placed on base plate 2 is not easy from falling down above, can when mounted support plate 5 and base plate 2 entirety be backward tilted at an angle.After installing base plate 2, respectively the first high-voltage oil cylinder 1, the second high-voltage oil cylinder 3 and third high compressing cylinder 4 are fixed on to upper, three of the left and rights direction of base plate 2, must guarantee the center line of three high-voltage oil cylinders in one plane; And the center line that the center line of second high-voltage oil cylinder 3 and third high compressing cylinder 4 is parallel to support plate 5, the first high-voltage oil cylinders 1 is perpendicular to support plate 5.Finally hydraulic control box 6 is installed, and all oil circuits, circuit are connected.
As shown in Figure 2, when the utility model work, first by the upright center that is lifted into base plate 2 of R type transformer core 8 of coiling moulding, then place prefabricated folder 9 in the surrounding of R type transformer core 8, button on operation hydraulic control box 6 makes three high-voltage oil cylinder pistons draw close to R type transformer core 8, now the action of the second high-voltage oil cylinder 3 and third high compressing cylinder 4 is by same group of button control, can guarantee like this travel synchronization of the piston of the second high-voltage oil cylinder 3 and third high compressing cylinder 4, make R type transformer core 8 remain at the center of base plate, and left and right is stressed evenly.When three high-voltage oil cylinders start to compress R type transformer core 8, measure length and the width dimensions of R type transformer core 8, stop pressurizeing and lock three hydraulic cylinders until meet the sized data of drawing requirement, then by folder 9 wedgings, operate three high-voltage oil cylinder pistons and reclaim and unclamp R type transformer core 8, finally R type transformer core 8 and folder 9 entirety are hung out to the utility model and carry out next process---high annealing.
