Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and method for recovering cutting chips and chips generated when cutting a noble metal material such as gold, platinum or silver.

[0002]

2. Description of the Related Art Conventionally, even a noble metal material such as gold, platinum or silver has been subjected to a standard cutting using a standard cutting machine.
When cutting gold, platinum, silver, palladium and precious metal materials such as their alloys, considering the high price of materials, ear materials, mill ends, and cutting chips, which are cutting residual materials, are highly pure and highly recovered without mixing. There is a need to. For that purpose, it is desirable that the cutting machine main body has a mechanism that prevents the accumulation of chips and filling in the gaps, and complete recovery of each material. Therefore, it is necessary to completely collect the ear material, the end material, and the cutting chips generated for each cutting material having the same composition. Even when a conventional standard type cutting machine is used, ear material and end material generated by cutting are recovered, but it is sufficient for the requirement of high recovery with high purity without mixing cutting residual materials as described above. Couldn't answer. In other words, the cutting powder that had fallen into the groove of the cutting machine was collected by cleaning the required points of the cutting machine. Further, when cutting various materials having different compositions, the chips were mixed and collected at the time of cleaning and collection. For this reason, the recovered chips have different compositions each time and cannot be used as the original material even if they are melted as they are. In a conventional cutting device, if a plurality of materials having different compositions are cut, the composition of the collected cutting chips changes every collection, and even if they are melted as they are, they cannot be used as the same material.

[0003]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve the above-mentioned problems of the prior art, collect selvedge material, mill ends and chips for each material, and use them as they are for the same raw material material. It is to provide a recovering device and method capable of melting.

[0004]

The above object of the present invention is a cutting device comprising an inlet side vise mechanism, a material cutting part and an outlet side vise mechanism, in which a selvage material and end material recovery mechanism provided below the material cutting part. , A chip blowing mechanism, a chip suction mechanism, and a chip collection mechanism that collects the chips collected by the suction mechanism, and collects the chips collected by the chip collection mechanism and the ear and end material collection mechanisms. The present invention has been achieved by a precious metal material cutting apparatus and a precious metal material cutting method using the same, which is capable of accumulating the cut material in one place for each cutting material.

Next, a preferred embodiment of the present invention will be described. The material conveyed by the inlet side vise mechanism is fixed by the vise and cut by the saw blade. The cut ear material and the end material are slid on the bed of the cutting machine main body from the drop opening which opens and closes left and right or up and down around the saw blade and is collected in the bucket. In order to prevent the chips generated during cutting from accumulating inside the cutting machine body, air is blown to blow the chips near the suction port, and the chips are generated and simultaneously removed by suction. The cutting machine main body is covered with a cover, and the cutting chips adhering to the saw blade are blown off by air nozzles or the like provided at multiple locations, and the saw blade itself is cooled. It is preferable that the chips accumulated around the saw blade of the cutting machine be blown toward a predetermined suction port to suck the collected chips. It is preferable to provide suction ports for cutting chips at a plurality of locations. Chips adhering and depositing around the vise for fixing the material and on the cutting machine bed are removed by a suction device having a moving suction port. The suction port can be moved manually or by using a robot. The chips that have been sucked and removed at the above two places are collected by a pipe and collected by a collection device such as a cyclone or a dust collector. A cyclone is more preferable as the collecting device in order to maintain the purity of the collected chips. It is desirable to cut out the collected chips in order using a double damper to prevent the chips from being blown out during collection. The ear material and the end material collected in the bucket and the chips collected by the dust collector are collected and collected for each material. The recovered material is melted again and cut into a uniform shape.
