Embodiment
The present invention is attached to the sweep-out method of oxide on the aluminium scrap wire rod of useless overhead transmission line and impurity not by handwork, and removed changing the oxide and the impurity that are adhered on the surface of the aluminium scrap wire rod branching away in the useless overhead transmission line occurring when overhead transmission line in automation mode, thereby can carry out easily the regeneration operation of aluminium scrap wire rod.
This can realize by following method, with straight line useless overhead transmission line without interruption and utilize multiple grinders that abrasive wheel intensity reduces successively grind according to the order of sequence its surface and effectively removed the oxide and the impurity that are adhered on its surface.
Therefore, the present invention can remove the oxide and the impurity that on the surface of useless overhead transmission line, are adhered to continuously in automation mode, so just can solve at one stroke prior art owing to carrying out the poor efficiency occurring, low productivity problem by handwork.
Describe preferred embodiment of the present invention in detail below in conjunction with accompanying drawing.
Fig. 1 is that the present invention is attached to the oxide and the sweep-out method flow chart of impurity on the aluminium scrap wire rod of useless overhead transmission line, and Fig. 2 is the process chart that the present invention is attached to the sweep-out method of oxide on the aluminium scrap wire rod of the overhead transmission line that gives up and impurity.
As shown in Figure 1, the sweep-out method of the oxide on the aluminium scrap wire rod that is attached to useless overhead transmission line of preferred embodiment of the present invention and impurity mainly comprises supply step S110, grinding steps S120, cleaning step S130 and curling step S140.
First, above-mentioned supply step S110 is: aluminium scrap wires W is pulled into after straight line without interruption.
That is, the bobbin B of the aluminium scrap wires W of reeling according to roll form is untied with certain rotary speed by dispenser device 100 and with linear fashion aluminium scrap wires W without interruption.
Then, above-mentioned grinding steps S120 for: remove utilizing grinder 200 to grind by above-mentioned supply step S110 with the surface of the aluminium scrap wires W of straight line supply the oxide and the impurity that on its surface, are adhered to.
Now, for the grinding scratch of effectively removing the oxide that adheres on aluminium scrap wires W surface and impurity and generating in its surface due to grinding operation, above-mentioned grinding steps S120 as illustrated in fig. 1 by grinding steps S121 for the first time, for the second time grinding steps S122 and for the third time grinding steps S123 form better.
The above-mentioned S121 of grinding steps for the first time for: for grinding for the first time and remove the oxide and the impurity that are adhered on its surface with the surface of the aluminium scrap wires W of straight line supply by above-mentioned supply step S110.
That is, use the first grinder 210 to grind for the first time the surface of aluminium scrap wires W, this first grinder 210 utilizes drive motors 212 to order about the first abrasive wheel 211 that the first steel brush forms to rotate according to certain speed.
Now, effectively remove oxide and impurity in order to utilize higher-strength to grind aluminium scrap wires W surface, above-mentioned the first steel brush is by possessing 250～300kgf/mm 2intensity and 0.4～0.5mm diameter person form better.
The above-mentioned S122 of grinding steps is for the second time: grind for the second time to remove for the surface of having carried out the aluminium scrap wires W of grinding for the first time by the above-mentioned S121 of grinding steps for the first time and remain in its surperficial oxide and impurity.
That is, use the second grinder 220 to grind for the second time the surface of aluminium scrap wires W, this second grinder 220 utilizes drive motors 222 to order about the second abrasive wheel 221 that the second steel brush forms to rotate according to certain speed.
At this, in order to utilize the surface of grinding aluminium scrap wires W lower than the intensity of above-mentioned the first steel brush to remain in its surperficial oxide and impurity effectively to remove, above-mentioned the second steel brush is by possessing 100～150kgf/mm 2intensity and 0.2～0.3mm diameter person form better.
The above-mentioned S123 of grinding steps is for the third time: grind for the third time and remove the upper scratch occurring in its surface for the surface of having carried out the aluminium scrap wires W of grinding for the second time by the above-mentioned S122 of grinding steps for the second time.
That is, use the 3rd grinder 230 to grind for the third time the surface of aluminium scrap wires W, the 3rd grinder 230 utilizes drive motors 232 to order about the 3rd abrasive wheel 231 that the 3rd steel brush forms to rotate according to certain speed.
Now, in order to utilize the surface of grinding aluminium scrap wires W lower than the intensity of above-mentioned the second steel brush effectively to remove because the above-mentioned S121 of grinding steps for the first time and grinding steps S122 for the second time occur in its lip-deep grinding scratch, above-mentioned the 3rd steel brush is by possessing 10～50kgf/mm 2the following diameter person of intensity and 0.1mm forms better.
Then, above-mentioned cleaning step S130 for: clean the aluminium scrap wires W that above-mentioned grinding steps S120 grinds.
That is, aluminium scrap wires W drop into cleaning machine 300 inner and allow its by utilize cleaning agent the S121 of grinding steps for the first time through above-mentioned grinding steps S120 and grinding steps S122 for the second time and for the third time grinding steps S123 be attached to its lip-deep abrasive material and clean up.
Then, above-mentioned curling step S140 is: in addition curling having cleaned surperficial aluminium scrap wires W in above-mentioned cleaning step S130.
That is, with roll form, aluminium scrap wires W is wound on by crimping machine 400 and drives the bobbin B of rotation according to certain speed to can carry easily and keeping.
Therefore, passed through above-mentioned all steps and just can obtain following aluminium scrap wires W, this aluminium scrap wires W removed on surface be wound on bobbin B with roll form under the state of the oxide that adheres to and impurity.
As previously mentioned, the present invention does not remove the oxide and the impurity that on the surface of aluminium scrap wires W, are adhered in automation mode by device by staff's handwork, thereby can carry out more easily the regeneration operation of aluminium scrap wires W.
Described embodiment, only for illustrating, has this area and conventionally knows that the knowledgeable is when realizing accordingly other variant embodiment of various variations.Therefore, the real technological right scope of the present invention should realize other various variant embodiment that comprise above-described embodiment including the invention technological thought of recording according to claims.
