Description

Automatic microchip discharging device for cutting processing {AUTOMATIC MICRO-CHIP DISCHARGING DEVICE FOR CUTTING WORK}

The present invention relates to an automatic microchip ejection device for cutting processing, and more specifically, to an automatic microchip ejection device for cutting processing to remove fine metal foreign substances remaining during machine tool processing.

In general, a chip discharge conveyor is provided to cutting machine tools (lathes, milling machines, drilling machines, etc.) and is a device that filters and separates and discharges cutting chips generated during work.

When processing metal cuttings using a machine tool, the frictional heat generated between the metal cuttings and the cutting tool is cooled, and cutting oil is supplied for precise processing of the metal cuttings and maintaining the life of the cutting tool.

The chip discharge conveyor uses a conveyor installed in an endless track to return the cutting chips discharged from the machine tool to a separate recovery box, and the coolant contained in the cutting chips passes through each gap in the conveyor. It is configured to be stored in a tank.

The cutting oil collected in the recovery box is re-supplied to the metal cuttings and cutting tools through a circulation device with cutting chips and foreign substances filtered out, and the cutting chips collected in the recovery box are discharged to the outside by hand.

Meanwhile, because the cutting oil could not sufficiently filter out fine cutting chips, there was a problem of it flowing into the recovery box and coolant tank or being re-supplied to the machine tool.

For this purpose, a chip removal conveyor has been proposed to crush and filter cutting chips generated from machine tools.

The conventional chip removal conveyor filters cutting chips through the discharge port and then finely crushes them through a cutter on a roller, so the use of the collection bin is efficient, but it is inconvenient because the operator has to clean the accumulated cutting chips directly, and it is difficult to filter out the cutting chips. Problems arose as fine cutting chips were not properly disposed of, blocking the flow of cutting oil or accumulating at the bottom of the coolant tank.

Therefore, there is a need to improve cutting chip discharge facilities to solve this problem.

The background technology of the present invention is disclosed in Korea Registered Utility Model Publication No. 20-0347000 (registered on March 26, 2004, title of invention: Discharge chip crushing device of chip discharge conveyor).

In an embodiment of the present invention, the lower surface of the second frame may be formed to be inclined in one direction so that the microchip accommodated inside the second frame is discharged to the outside of the second frame.

In an embodiment of the present invention, the collecting part may be made of a magnetic material extending upward from the inner bottom surface of the first frame.

In an embodiment of the present invention, when the second frame is operated to raise, the second frame is spaced apart from the inside of the first frame, and when the second frame is operated to be lowered, the second frame is spaced apart from the inside of the first frame. The second frame is restrained, and the sweeper can be moved up and down along the outer peripheral surface of the magnetic material through the operation of the second frame.

In an embodiment of the present invention, a stopper may be inserted through the upper side of the second frame to face each upper end of the magnetic material and serve as a reference for mutual coupling of the first frame and the second frame.

In an embodiment of the present invention, the stopper and the sweeper may be made of MC nylon (monomer casting nylon).

In an embodiment of the present invention, the filter unit may be provided with a metal mesh net for filtering out the fine chips, and a handle may be formed for attachment and detachment to the main body unit.
