An inverter double-feeding brazing wire band armature brazing machine and its welding process

Abstract

The invention discloses an inverse armature brazing machine with double feeding of brazing wire belts and a welding technology thereof. The inverse armature brazing machine comprises an armature preparation plate, a machine base, a loading supporting base, a servo clamping and indexing mechanism, an armature loading supporting roller mechanism, an armature supporting rectification mechanism, a wire pressing and welding mechanism, a first brazing wire belt feeding mechanism, a second brazing wire belt feeding mechanism, a brazing filler metal plate and a smoke absorption mechanism. According to the machine, the brazing wire belts can be fed to the welding areas between outer-layer wires and inner-layer wires and the welding areas between the inner-layer wires and a commutator segment at the same time so as to be located in the middle of a conducting loop in welding and become the largest heat emission spot, and therefore the problem that a commutator emits heat excessively and then becomes expanded and deformed in the traditional lateral brazing wire belt feeding and welding process is solved, and the problems that temperature rise is excessive and the service life is short due to the small sectional area of arc welding connection and welding spot connection caused by single feeding of the brazing wire belts are solved; two wire processes of argon arc welding are eliminated in the armature welding process, the welding efficiency is high, welding is more reliable, less brazing filler metal is used, and the welding benefit is better.

Description

technical field [0001] The invention relates to an inverter double-feeding wire belt armature brazing machine and a welding process thereof. Background technique [0002] The traditional armature brazing machine has uneven distribution of solder, poor welding effect, poor precision, complex structure, troublesome maintenance, high cost, excessive heating of the commutator segments caused by traditional lateral wire feeding and expansion deformation, single feeding brazing Ribbon leads to the problem of excessive temperature rise and life reduction of the armature due to the small connection cross-sectional area of ​​the arc welding connection solder joints, and the original process needs to first argon arc weld two wires, and then send a brazing ribbon to weld the wires and replace them Welding to the welding area between the device pieces increases the number of procedures. Each procedure is mainly manual operation, manual adjustment, and manual monitoring. The stroke of ea...

Problems solved by technology

[0003] The purpose of the present invention is to solve the above-mentioned problems existing in the prior art. On the existing basis, a kind of wire ribbon mechanism that can be provided with more than two brazing wires is provided to carry out the outer layer wire and the inner layer wire, the inner layer wire and the commutator. The two welding areas between the sheets are simultaneously fed with brazing wires, so that the brazing wires are located in the middle of the conductive circuit during welding and become the largest heat point, which solves the problem of excessive heating and expansion of the commutator during traditional lateral brazing wires welding. At the same time, it also solves the problem of excessive temperature rise and short life of the armature during the use of the armature due to the small connection cross-sectional area of ​​the arc welding connection caused by the single feeding ribbon; the welding process reduces the two wires of argon arc welding and reduces the production Manual, which improves the production efficiency, the solder is evenly and fully distributed, and has a good welding effect; the servo clamping indexing mechanism has accurate indexing and humanized electronic control operating system, which is easy to operate, safe, simple to maintain, and has strong anti-interference ability. The failure rate is extremely low and the cost is low. It realizes intelligently completing a series of complex welding processes such as preloading, pressurization, pre-welding, ramp-up, first welding, second welding, multi-pulse, tempering, and ramp-down. , and can intelligently display the welding current and welding time, complete fault self-inspection, automatic alarm and other operations, it can also alarm and display the temperature overrun, drive module, current overrun, etc., the welding efficiency is high, the welding is more reliable, and at the same time Reduce the use of brazing material, the inverter double-feeding brazing wire belt armature brazing machine with higher welding efficiency and its welding process
