Embodiment 1

[0035] A small-capacity oil transformer low-voltage coil foil winding, such as Figure 1-Figure 3 As shown, the body 1 is included, the inside of the body 1 is rotatably connected with a winding shaft 2, the surface of the winding shaft 2 is welded with a winding block 3, the front part of the body 1 is clamped with a block 4, and the front part of the block 4 is provided with a Automatic sheet sticking mechanism 5, the inside of body 1 is positioned at the rear portion of bobbin 2 and offers limit groove 6, and the inside of body 1 is positioned at the rear portion of bobbin 2 and is welded with base 7, and the front portion of base 7 is provided with shaping device 8.

[0036] In this embodiment, the automatic film sticking mechanism 5 includes a moving seat 51, the surface of the moving seat 51 is welded and fixed to the front of the block 4, and the inside of the moving seat 51 is connected to a spray column 52 for rotation, and the moving seat 51 is located at the spraying...

Embodiment 2

[0038] Such as Figure 4-Figure 7 As shown, the interlocking device 56 includes a rotating shaft 1 561 and a main roller shaft 567. Both ends of the rotating shaft 561 are connected to the interior of the fixed table 55 for rotation. The surface of the rotating shaft 561 is welded with a push gear 562. The left side of the push gear 562 A pusher 563 is arranged on the side, the surface of the pusher gear 562 is meshed with a control half gear 564, the inner rotation of the control half gear 564 is connected with a rotating shaft 2 565, and the surface of the rotating shaft 2 565 is located at the bottom of the control half gear 564, and a starting device 566 is provided. The surface of the main roller shaft 567 is welded with a shearing gear 568, the surface of the shearing gear 568 is meshed with a reverse gear 569, and the inside of the reverse gear 569 is welded with a roller shaft, which passes through the belt and the auxiliary gear inside the right side cutting device 58....

Embodiment 3

[0045] Such as Figure 8 As shown, the shaping device 8 includes a pressing spring 81, the rear end of the pressing spring 81 is welded and fixed to the front portion of the base 7, the front end of the pressing spring 81 is welded with a pressing block 82, and both sides of the pressing block 82 are welded with sliding The arm 83, the surface of the sliding arm 83 is slidingly connected with the inner wall of the limiting groove 6. By setting the shaping device 8, when the winding block 3 rotates and wraps, it is in continuous contact with the pressing block 82, thereby passing through the rear part of the pressing block 82. The impact of the elastic force of the pressing spring 81 achieves the effect of being squeezed, thereby achieving the effect of squeezing and shaping the copper coil wound on the surface of the winding block 3, and further achieving the effect of making the width of the coil better. By setting the sliding arm 83 The surface of the surface is slidingly co...

Abstract

The invention relates to the technical field of coil foil winding, and discloses a small-capacity oil-to-low voltage coil foil winding which comprises a machine body. A winding shaft is rotatably connected to the interior of the machine body, a winding block is welded to the surface of the winding shaft, a clamping block is clamped to the front portion of the machine body, and an automatic sheet sticking mechanism is arranged on the front portion of the clamping block. A limiting groove is formed in the position, located on the rear portion of the winding shaft, in the machine body, a base iswelded to the position, located on the rear portion of the winding shaft, in the machine body, and a shaping device is arranged on the front portion of the base. According to the low-capacity oil-to-low voltage coil foil winding, the effects of automatically adhering and fixing insulation paper to the winding block and automatically cutting the insulation paper after the insulation paper is woundby a circle are achieved through the automatic sheet sticking mechanism and the shaping device, and therefore the situation that an operator cannot conduct other work due to the fact that the operatoris beside a machine body for a long time is avoided; the effect of automatically extruding and shaping the foil-wound copper coil on the surface of the winding block is achieved, and the effect of enabling the coil to be better in the radial direction is further achieved.

Description

technical field [0001] The invention relates to the technical field of coil foil winding, in particular to a small-capacity oil transformer low-voltage coil foil winding. Background technique [0002] The foil winding machine series adopts PLC automatic control frequency conversion stepless speed regulation system, photoelectric hydraulic deviation correction system, automatic welding mechanism and other automatic control functions to ensure the welding quality of transformer winding foil and greatly reduce the loss of transformer. Foil winding machine In the past, it was mainly used for winding high-voltage windings of dry-type transformers. In the future, it will be more used for winding oil-immersed transformers. It has high efficiency and good winding quality, especially for household appliances experimental equipment. The material consumption of the whole transformer improves the short-circuit stress characteristics of the coil. [0003] The small-capacity oil transfor...
