Abstract

The utility model relates to a device for the manufacturing of a wound iron core of a transformer, which comprises a roll which is provided with a steel strip. A guide roller of the steel strip and a rod linkage mechanism in two groups of material feeding pairs in an automatic regulation pair of the steel strip are arranged on a base seat. A mould plate of the iron core is arranged on a shaft of a main shaft box. A pinch roller which is connected with a cylinder is arranged under the mould plate of the iron core. The rotating speed of a main shaft and the pressure of compressed air of the cylinder is regulated, which makes the steel strip wound on the mould plate of the iron core in a selected speed. The wound iron core of an R-type transformer is formed by the utility model. The error of the size and shape of the circular section of the wound iron core satisfies requirements. No gaps are generated between iron core layers. The utility model has the advantages of convenient operation and high production efficiency.

Description

Make the device of transformer Wound core

The utility model relates to a kind of manufacturing transformer Wound core isolated plant.

The transformer of Wound core and laminated core structure transformer are relatively, it is little to have leakage field, economize with material, noise is little, in light weight, wave mode can not produce advantages such as distortion, but the domestic Wound core transformer of why failing to produce and promote the use of? main cause is its manufacturing process complexity, making iron core requires to press the not circular section diameter dimension of Capacity design, cut out the long steel band of the continuous expansion of every layer of variation of width, again with the circular section iron core of steel coil strip coiled design size, and make the size and dimension error of iron core circular section meet the design accuracy requirement, therefore the special equipment that meets technological requirement must be arranged, just can possess working condition and produce the product that satisfies quality requirement.Especially the transformer of larger capacity is rolled up iron core, and domestic product-free still for producing serial Wound core power transformer product, must at first solve the technology assembling of Wound core key.

The purpose of this utility model is: the device of the manufacturing transformer Wound core that designs for the technology that solves Wound core.

In order to achieve the above object, the technical solution adopted in the utility model is: it comprises the reel that the steel band coiled strip is housed, two guide rollers that can penetrate steel band in the centre are housed on pedestal, guide roller is on the base rail successively of a right left side, two groups of feeding centering linkages steel band can being regulated automatically centering are housed, the iron core template that can rotate with machine mandrel is housed in the machine mandrel of main spindle box, the pinch roller that can be pressed on the Wound core side is housed below the iron core template successively, the wheel pressing shaft that links to each other with cylinder is connected with guide pad, guide pad drive pinch roller can the gathering sill on guide plate in slippage up and down.

Below in conjunction with accompanying drawing, the utility model is described in detail.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a structure vertical view of the present utility model.

As Fig. 1, shown in Figure 2, it comprises the reel 1 that steel band 2 coiled strips are housed, two guide rollers 3 that can penetrate steel band 2 in the centre are housed on pedestal 4, guide roller 3 is from pedestal 4 guide rails successively of a right left side, two groups of feeding centering linkages steel band can being regulated automatically centering are housed, the iron core template 12 that can rotate with machine mandrel is housed in the machine mandrel of main spindle box 11, the pinch roller 15 that can be pressed on Wound core 13 sides is housed below iron core template 12 successively, the axle 17 of the pinch roller 15 that links to each other with cylinder 18 is connected with guide pad 16, guide pad 16 drive pinch rollers 15 can be in the gathering sill on the guide plate 14 about slippage.

As shown in Figure 1 and Figure 2, described two groups of feeding centering linkages are installed in the slide block 5 that is hung with pouring weight 24 on the guide rail of pedestal 4 respectively, one end of two connecting rods 23 is connected with another slide block 6, the other end of two connecting rods 23 is point articulated at a with an end of two other connecting rod 22 respectively, and the other end of other two connecting rods 22 connects centering roller 7 respectively through fulcrum b; The slide block 8 that is hung with pouring weight 21 is installed on the guide rail of pedestal 4, one end of two connecting rods 20 is connected with another slide block 9, the other end of two connecting rods 20 is point articulated at c with an end of two other connecting rod 19 respectively, and the other end of other two connecting rods 19 connects centering roller 10 respectively through fulcrum d.

Select iron core template 13 by the different model iron core, iron core template 13 is contained in the machine mandrel of coiler device main spindle box 11, the steel band coiled strip that shears is mounted on the reel 1, adjust the position of iron core template 13 and two groups of feeding centering linkages, two guide rollers 3, coiled strip is unclamped, steel band 2 is penetrated in two guide rollers 3 and two groups of feeding centering linkages to being connected between two groups of centering rollers 7,10 and with iron core template 13.Adjust the compressed air pressure of the speed of mainshaft and cylinder 18, start motor, steel band 2 will be wound on the iron core template 12 by selected rotating speed.In the steel band winding process, the axle 17 of the pinch roller 15 that links to each other with cylinder 18 is connected with guide pad 16, guide pad 16 by the thrust of cylinder 18, makes pinch roller 15 be pressed on steel band 2 surfaces of Wound core 13 all the time along the gathering sill on the guide plate 14, makes steel band 2 rolling-in layer by layer and does not produce the gap.Two groups of feeding centering linkages are in the steel disc winding process, two pouring

weights

24,21 that dependence is hung with pulley make the

slide block

5,8 that is contained on pedestal 4 guide rails make move left and right respectively, the

slide block

6,9 that two

slide blocks

5,8 promote respectively to be contained on pedestal 4 guide rails is made move left and right simultaneously, automatically regulate two groups of centering roller 7,10 foldings and the steel band thrust of different in width is remained unchanged substantially, make the steel band center consistent, to guarantee the size and dimension precision of Wound core 13 circular sections with iron core template 12 centers.

The operation principle of two groups of feeding centerings of description linkage in the steel disc winding process of following mask body is respectively: an end of two connecting rods 23 is connected with slide block 6, the other end of two connecting rods 23 is point articulated at a with an end of other two connecting rods 22 respectively, the other end of other two connecting rods 22 connects centering roller 7 respectively, when slide block 5 promotion slide blocks 6 move, two connecting rods 23 make other two bars 22 rotate around the b point through pin joint a, promote 7 foldings of centering roller respectively, make centering roller 7 be pressed on the two sides of different in width steel band 2 all the time; One end of two connecting rods 20 is connected with slide block 9, the other end of two connecting rods 20 is connected centering roller 10 respectively with the other end of other two connecting rods 19 respectively, when slide block 8 promotion slide blocks 9 move, two connecting rods 20 make other two connecting rods 19 rotate around a point through pin joint c, promote 10 foldings of centering roller respectively, make centering roller 10 be pressed on the two sides of different in width steel band 2 all the time.

The advantage that the utlity model has is:
