Problems solved by technology
The disadvantages are ① the heat generated during welding will burn the inter-turn insulation or cause the inter-turn insulation to age, resulting in poor inter-turn withstand voltage and shortening the service life of the motor; The wire ends are loose, and the turn-to-turn insulation at the welding point is loose from the magnet wire, which is prone to turn-to-turn defects during the subsequent motor assembly process; ③ welding points are prone to defects such as poor welding, uneven surface, and over-thickness

The invention provides a magnetic pole open-ended coil end formation tool, relates to the magnetic pole open-ended coil end formation tool, which can be applied to a DC motor stator and a synchronous motor rotor, and is mainly to solve the problem that, at present, when a magnetic pole open-ended coil is prepared, leading-out coil ends and a coil body are produced and formed separately, and during welding, turn-to-turn insulation is burnt, and thus the server life of a motor is reduced. Two mutually-parallel outer side plates are fixedly arranged on a bottom board; a semi-H-shaped baffle plate is fixedly arranged between the two outer side plates; the open end of the semi-H-shaped baffle plate is fixedly provided with a pressure plate, and the bottom board at the end is fixedly provided with a baffle plate; the baffle plate is fixedly provided with a pressure plate, the two ends of which respectively have a pressure head; and the bottom board and the baffle plate at the end are respectively provided with a cylindrical pin. An open magnetic pole coil with the leading-out coil ends and the coil body being integrated can be prepared, thereby preventing the defect of poor turn-to-turn voltage withstand due to burning of turn-to-turn insulation or aging of the turn-to-turn insulation caused by heat generated during welding, and improving production efficiency.
Description
technical field [0001] The invention relates to a forming tool for a magnetic pole open coil wire end, in particular to a magnetic pole open coil wire end forming tool which can be used for a DC motor stator and a synchronous motor rotor. Background technique [0002] The production process of magnetic pole open coil includes: winding, annealing, bulging, shaping, padding between turns, baking and pressing, shoveling between turns, electrical inspection, lead-out production, welding lead-out, grinding and polishing, wrapping insulation. At present, when making the open coil of the magnetic pole coil, the leading wire head and the coil body are formed separately and then welded together. The disadvantages are ① the heat generated during welding will burn the inter-turn insulation or cause the inter-turn insulation to age, resulting in poor inter-turn withstand voltage and shortening the service life of the motor; The wire ends are loose, and the turn-to-turn insulation at th...
