Problems solved by technology
[0003] The traditional process is to electroplate the tin alloy strip on the surface of the copper alloy strip. After a long time of use, the tin alloy strip will fall off from the copper alloy strip. The commutator stops working, without the function of the commutator, the motor will be stuck after less than half a circle

Embodiment Construction
[0021] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0022] Such as Figure 1 to Figure 3 As shown, the continuous strip complex solder strip processing technology includes the following steps: Step 1, prepare the solder strip and the material strip, the solder strip is tin alloy strip 1, and the material strip is copper alloy strip 2; Step 2, pass The positioning mold 3 positions the tin alloy strip 1 on the welding surface of the copper alloy strip 2; step 3, heat-presses the tin alloy strip 1 by a hot pressing roller, so that 10% to 15% of the area of the tin alloy strip 1 is aligned with the copper alloy strip 1. Strip 2 is welded; step 4, welding treatment: the tin alloy strip 1 is completely welded on the welding surface of the copper alloy strip 2; step 5, strip processing: the strip after welding is stripped by a slitting machine to obtain The actual required size; Step 6, the finished product is delivered, ...

Abstract
The invention relates to the technical field of soldering technologies, in particular to a processing technology for a continuous strip compound solder band material and a solder band material. The processing technology comprises the following steps of 1, preparing a solder band and a material band, wherein the solder band is a tin alloy band, and the material band is a copper alloy band; 2, positioning the tin alloy band on the soldering surface of the copper alloy band through a positioning mold; 3, performing hot-pressing treatment on the tin alloy band through a hot-pressing roller, so that the area, soldered with the copper alloy band, of the tin alloy band is 10-15 percent; 4, performing fusion soldering treatment, namely completely soldering the tin alloy band on the soldering surface of the copper alloy band; 5, performing strip dividing treatment on the soldered material bands through a strip dividing machine to obtain sizes which are practically needed; 6, producing, packaging and warehousing a finished product. The tin alloy band is soldered on the surface of the copper alloy band through a fusion soldering technology and is not easy to disengage, so that a commutator can normally work.
Description
technical field [0001] The invention relates to the technical field of welding technology, in particular to the processing technology of continuous strip re-solder strip and the solder strip. Background technique [0002] The continuous strip of compound solder strip is the main material for making the internal contact piece of the commutator, including copper alloy strip and tin alloy strip. The tin alloy strip is provided with several installation slots for placing coils. When the coil passes through the current, it will Under the action of the permanent magnet, it rotates through the attraction and repulsion force. When it turns to balance with the magnet, the contact piece on the corresponding commutator of the original electrified line is separated from the brush, and the brush is connected to the commutator. On the contact piece corresponding to the group of coils that generate the driving force, repeat this non-stop, and the DC motor will rotate. [0003] The traditi...
