Abstract
The invention provides a tightening method for a wire head of an electric brush. The method comprises the following steps: compressing a wire and the body of the electric brush into one electric brush product; heating, melting and tightening a head of the wire of the electric brush product; and carrying out the high-temperature sintering of the electric brush product with the head of the wire being tightened in protection gas. The method changes the tinning technology into heating, melting and tightening of the head of the wire, and enables the tightening of the head of the wire to be completed before the high-temperature sintering, thereby enabling a wire head oxidation phenomenon liable to happen during point welding to happen during the sintering of the electric brush so that the protection gas for sintering can restore the oxidized wire into a good product. Therefore, the method can save time and labor in a production process of the electric brush under the condition of meeting the requirements of a customer for the quality of the electric brush product, is environment-friendly, is stable in quality, and is easy to control.

On connecting terminal or on brush box connection post, ultimately form power circuit motor and just can get into smooth.
Owing to brush lead needs certain suppleness, so brush lead typically uses thinner copper wire multiply to compile
Knit or stranded form, when every brush produces to wire cutting during, wire the end of a thread there will be to a certain degree
Phenomenon of scattering, if be not acted upon, wire easily occur when being connected with motor spot welding/scolding tin bad (dissipate
Silk, fracture of wire, rosin joint etc.), if the copper cash of filoselle and chassis contact even have the risk of short circuit, so one
As producer be desirable that brush lead the end of a thread is tightened up process by brush manufacturer.
As shown in technique before the change in Fig. 1, the tradition mode of tightening up is after brush machines, manually to line
Head is smoothed out with the fingers and is tightly stained with high temperature scolding tin the most again and carries out tightening up process, and this mode shortcoming is: tin sticky the end of a thread unsightly,
Scolding tin not environmentally, after high temperature tin sticky wire easily aoxidize, cost of labor higher.
Summary of the invention
It is an object of the invention to provide a kind of brush lead the end of a thread tightening up method system, it is possible to solve tin sticky the end of a thread
Unsightly, the problem that scolding tin is not environmentally, wire easily aoxidizes, cost of labor is higher after high temperature tin sticky.
For solving the problems referred to above, the present invention provides a kind of brush lead the end of a thread tightening up method, including:
Wire and brush brush body are pressed into and are integrally formed brush product；
Heating and melting also tightens up the termination of wire of described brush product；
The brush product of the termination of described stringing lead is carried out high temperature sintering in protective gas.
Further, in the above-mentioned methods, by the brush product of the termination of described stringing lead at protective gas
In carry out high temperature sintering step after, also include:
According to preset dimension requirement, the brush product after high temperature sintering is carried out dimensioned.
Further, in the above-mentioned methods, heating and melting tighten up the termination of wire of described brush product
In step,
Heating and melting tighten up the termination of wire of described brush product by the way of spot welding.
Further, in the above-mentioned methods, the mode of described spot welding includes manual spot welding or automatic spot.
Further, in the above-mentioned methods, heating and melting tighten up the termination of wire of described brush product
In step,
By mash welder heating and melting the termination of the wire tightening up described brush product
Further, in the above-mentioned methods, described protective gas uses hydrogen.
Further, in the above-mentioned methods, described wire is copper cash.
Further, in the above-mentioned methods, described copper cash is woven by the copper wire multiply of diameter 0.05-0.12 or strand
Conjunction forms.
Compared with prior art, the present invention is integrally formed brush product by wire and brush brush body being pressed into
Product；Heating and melting also tightens up the termination of wire of described brush product；Electricity by the termination of described stringing lead
Brush product carries out high temperature sintering in protective gas, thus changes tin sticky technique into heating and melting stringing lead
Termination, and complete before the operation of the termination of stringing lead is changed to high temperature sintering, easily occur during such spot welding
The end of a thread oxidative phenomena can when brush sinters, even if protective gas during sintering can by oxidation wire also
Former one-tenth non-defective unit, thus, it is possible to meet client to brush product quality require on the premise of, make brush produce
During time saving and energy saving, environmental protection, steady quality, easily controllable.
Accompanying drawing explanation
Fig. 1 is brush lead the end of a thread tightening up method of one embodiment of the invention and existing methodical comparison diagram；
Fig. 2 is the flow chart of brush lead the end of a thread tightening up method of one embodiment of the invention.
Detailed description of the invention
Understandable for enabling the above-mentioned purpose of the present invention, feature and advantage to become apparent from, below in conjunction with the accompanying drawings and
The present invention is further detailed explanation for detailed description of the invention.
As illustrated in fig. 1 and 2, the present invention provides a kind of brush lead the end of a thread tightening up method, including:
Step S1, is pressed into wire 2 and brush brush body 1 and is integrally formed brush product；
Step S2, heating and melting also tightens up the termination 3 of wire of described brush product；
Step S3, carries out high temperature burning by the brush product of the termination 3 of described stringing lead in protective gas
Knot.Here, the present invention changes the termination of heating and melting stringing lead into by tin sticky technique, and will tighten up and lead
The operation of the termination of line completes before changing to high temperature sintering, and the end of a thread oxidative phenomena easily occurred during such spot welding can be
During brush sintering, even if the wire of oxidation can be reduced into non-defective unit by protective gas during sintering, thus, energy
Enough meeting on the premise of brush product quality requires by client, it is time saving and energy saving to make in brush production process, ring
Guarantor, steady quality, easily controllable.
Preferably, as illustrated in fig. 1 and 2, step S3, the brush product of the termination of described stringing lead is existed
After protective gas carries out high temperature sintering, also include:
