Embodiment Construction

[0018] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0019] see Figure 1-4 , a coil transposition bending tool, which includes a first bending tool and a second bending tool.

[0020] The first wire bending tool includes a cuboid head 2 made up of two cuboid metal blocks of the same size and a rod-shaped handle 3 vertically connected to one of the head metal blocks, each of the two ends of the two metal blocks has a Screw holes, they can be detachably combined by screws 1 and 1'; the upper and lower long sides of the cuboid metal block of the head are all inverted at an angle of 45 degrees to the short side of the side.

[0021] The second wire bending tool includes a T-shaped head 8 made up of two T-shaped metal blocks of the same size and a rod-shaped handle 7 that is vertically connected to one of the T-shaped metal blocks of the head. Each of the three free ends of the block has a screw hole, and th...

Abstract

The invention relates to the field of tools for manufacturing transformers, in particular to a coil transposition wire bending tool and a using method. The coil transposition wire bending tool consists of a first wire bending tool and a second wire bending tool. The first wire bending tool comprises a cuboid head which consists of two cuboid metal blocks with a same size and a bar-shaped handle which is vertically connected with one of the head metal blocks. Two ends of the two metal blocks are respectively provided with a threaded hole. The two metal blocks can be combined together in a detachable way by a screw. The second wire bending tool comprises a T-shaped head which consists of two T-shaped metal blocks with the same size and a bar-shaped handle which is vertically connected with one of the head T-shaped metal blocks. Three free ends of the two T-shaped metal blocks are respectively provided with a threaded hole. The two T-shaped metal blocks can be combined together in a detachably way by a screw. By adopting the technical proposal, the tool can bend crude and hard wires in a narrow gap so as to lead to convenient transposition of conductors in the process of coil winding and realize continuous coil enwinding.

Description

technical field [0001] The invention relates to the field of transformer manufacturing tools, in particular to a coil transposition bending tool and a use method. Background technique [0002] In the dry transformer manufacturing process, the winding process of the coil is a very important link. At present, the epoxy high-voltage coil of the dry transformer adopts a soft mold process integrating winding and casting, which has low manufacturing cost and fast cycle time. When the soft mold process is used for winding, according to the needs of manufacturing, the winding is to wind several rows and layers in a certain place of the coil to meet certain requirements, and then wind to another place adjacent to the coil. . The distance between the two winding positions on the coil coil is 10mm, and the coil of 800 kVA and above is wound, the thickness of the wire will be 2mm and the width is more than 8mm, and such copper flat wire should be bent and transposed (bending 2 90-deg...
