Manual bending tool

Abstract

The invention provides a manual bending tool. The manual bending tool comprises a stud, a plate II, a T-shaped column I, a T-shaped column II, a handle I and a handle II, wherein the stud is arranged on the central axis of a plate I, the plate II is rotatably connected with the plate I through the stud, the T-shaped column I and the T-shaped column II are arranged on opposite sides of the plate I and the plate II, the handle I and the handle II are connected with the tail end of the plate I and the tail end of the plate II correspondingly, and the plate II and the plate I can be disassembled. According to the manual bending tool provided by the invention, slow and smooth transition of a right-angle bend is achieved; and the structure is simple, light and handy, operation is convenient, the degree of damage to a coil wire can be reduced to the maximum extent while the right-angled bend is slowly manufactured through bending, copper exposure is avoided, and a wire film is not damaged. On the small aspect, the work of removing all insulating materials of the wire and checking the wire by an operator and the rework of re-binding are avoided, and time and labor are saved. On the big aspect, the situation that burrs are generated due to friction or the insulating film is broken in the bending process of the wire is avoided, the potential safety hazards such as coil short and transformer halts are reduced.

Description

technical field [0001] The invention relates to the technical field of wire bending, in particular to a manual bending tool capable of realizing slow bending of slightly damaged wires. Background technique [0002] The winding process of the core structure winding inside the transformer needs to make right-angle bends, especially the spiral structure coils, and the right-angle bends are generally in the first position. The less damage to the right-angle bends, the better for the transformer. The existing manual right-angle bending tools are relatively bulky, about 1000mm in length, and about 8.3kg in weight. The arc radius of the right-angle bend is relatively small, which is easy to damage the wire. Because the structure of the bending tool directly determines the bending direction, the right angle produced by the bending tool is relatively sharp, and the copper wire is easily exposed due to insulation damage. Generally, it is necessary to remove all the insulation, check...

Problems solved by technology

The existing manual right-angle bending tools are relatively bulky, about 1000mm in length, and about 8.3kg in weight. The arc radius of the right-angle bend is relatively small, which is easy to damage the wire

Because the structure of the bending tool directly determines the bending direction, the right angle produced by the bending tool is relatively sharp, and the copper wire is easily exposed due to insulation damage.

Generally, it is necessary to remove all the insulation, check whether the copper wires are damaged, deal with the damaged wires individually, and then re-insulate them in a unified way. When there are many coil wires, the workload is very heavy.
