Abstract
The invention disclose a method for clearing plastics on a metal piece of a scrapped workpiece. Firstly, the scrapped workpiece is heated so that the plastics of the scrapped workpiece is melted; then the scrapped workpiece is rotated with high speed, and the melted plastics is thrown out of the scrapped workpiece by utilizing the principle of centrifugal force; and finally the metal piece is separated from the plastics of the scrapped workpiece. The invention further discloses a plastic clearing machine which comprises a rotating device driving a workpiece to rotate and a heating device arranged outside the workpiece. By utilizing the principle that the melting point of the plastic is lower than that of the metal and the principle of centrifugal force, the invention can effectively remove the plastics on the metal piece of the scrapped workpiece for recovering and reusing the metal piece, so that the waste can be reduced and the cost can be greatly reduced.
Description
Technical field
The present invention relates to a kind of removing and scrap the method for plastics on the metalwork of workpiece, and a kind of being used for will be scrapped the clear molding machine that plastics are peeled off on the metalwork of workpiece.
Background technology
At present, all form jointly by plastics and metalwork by the part of many products, this when being operated in injection moulding, metalwork is positioned in the mould as core, inject the plastics of molten condition then, cooling back plastic overmold is outside metalwork.And workpiece is when injection mo(u)lding, waste product can appear unavoidably, various parts also may be because of scrapping accidentally when being assembled into finished product, though the workpiece major part of scrapping is that metalwork is intact because parts of plastics damages, but because after part makes, plastics are coated on the metalwork surface tightly, are difficult to both be separated again, and therefore the work of scrapping can only be dropped.Abandoning the former prices of raw and semifnished materials of way of useless workpiece is generally adopted lower the time, but along with raw-material price in recent years rises steadily, especially the metalwork in the workpiece often is just not low copper material or other precious metal of price basis, and this has increased the weight of the burden of enterprise.
For this reason, there is the dealer to begin to consider that the metalwork in the workpiece reclaims, can utilizes again, then can melt down use for what damaged for intact metalwork.But how to reclaim the metalwork in the workpiece? adopt not only inefficiency of artificial mode, parts of plastics also is difficult to be stripped from totally, has also increased cost of labor virtually.The inventor concentrates on studies at the problems referred to above, has this case to produce finally.
Summary of the invention
The method of plastics on the metalwork that technical problem to be solved by this invention is to provide a kind of removing to scrap workpiece, its parts of plastics on can the metalwork that will scrap workpiece is easily and effectively removed clean, to reach the purpose that reclaims metalwork.
Another technical problem to be solved by this invention is to provide a kind of clear molding machine of can be effectively the parts of plastics of scrapping outside the metalwork of workpiece being peeled off.
For solving the problems of the technologies described above, technical solution of the present invention is:
The method of plastics on the metalwork of workpiece is scrapped in a kind of removing: at first heat scrapping workpiece, the parts of plastics that is heated to workpiece is molten condition, high speed rotational workpieces then, utilize centrifugal principle that the plastics of molten condition are thrown away from the workpiece metal part, thereby the metalwork of workpiece is separated with parts of plastics.
A kind of clear molding machine, it comprises the whirligig that can drive workpiece rotation and is arranged at heater outside the workpiece.
Described whirligig comprises a motor, and the main shaft of motor connects with workpiece.
The main shaft of described motor connects with a rotating shaft by shaft coupling, and workpiece then is fixed in this rotating shaft.
Described rotating shaft upper fixed has a special fixture, the metalwork part of this clamp clamps workpiece.
The zone of heating inside of described heater is hollow, and its arranged outside has thermal insulation layer.
Described heater is provided with a thermocouple.
The one recovery bucket that can take out is set in the described zone of heating.
After adopting such scheme, the present invention utilizes the fusing point of the plastics principle lower than metal, heat scrapping workpiece earlier, make its parts of plastics be molten condition, and then utilize centrifugal principle, the plastics by the high speed rotational workpieces with molten condition throw away from metalwork, can reach like this and effectively peel off the purpose of scrapping the plastics on the workpiece metal part, so that the metalwork of removing plastics is carried out recycling, thereby can cut the waste, and can significantly reduce cost.
Description of drawings
Fig. 1 is the functional-block diagram of the method for the invention;
Fig. 2 is the structure principle chart of clear molding machine of the present invention.
The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
Disclosed is a kind of removing and scrap the method for plastics on the metalwork of workpiece, as shown in Figure 1, at first heat scrapping workpiece, the parts of plastics that is heated to workpiece is molten condition, high speed rotational workpieces then, utilize centrifugal principle that the plastics of molten condition are thrown away from the workpiece metal part, thereby the metalwork of workpiece is separated with parts of plastics.
The invention still further relates to a kind of clear molding machine, as shown in Figure 2, be the preferred embodiment of clear molding machine of the present invention.Described clear molding machine mainly comprises whirligig 1 and heater 2.Wherein:
Described whirligig 1 comprises a motor 11, and the main shaft of motor 11 connects with a rotating shaft 13 by shaft coupling 12, and heater 2 inside are stretched in rotating shaft 13.
Zone of heating 21 inside of described heater 2 are hollow, and its arranged outside has thermal insulation layer 22, and heater 2 also is provided with a thermocouple 23, are used to measure the temperature in the zone of heating 21.
The operation principle of described clear molding machine is: heat by 2 pairs of workpiece that insert into the inner 3 of heater, make the parts of plastics of workpiece 3 be molten condition, starter motor 11 then, drive workpiece 3 rotation at a high speed, the plastics of molten condition throw away from metalwork under action of centrifugal force like this, thereby reach the purpose that the parts of plastics of scrapping workpiece is separated with metalwork.And, a recovery bucket 5 that can take out can be set in zone of heating 21 for plastics recovery, and when being thrown out of, plastics can be stored in this recovery bucket 5, thus convenient the recovery.
