Description

[Detailed description of the invention] The invention is designed to send out both fine shavings such as Sekikoshi casting swarf and curled and entangled iron shavings to a swarf delivery pipe installed at the discharge ports of multiple screw conveyors. It is an object of the present invention to provide a cutting swarf delivery tube that can

Conventionally, if the lathe is small, the screw conveyor that is installed below the lathe can be installed with the screw axis in the same direction as the main axis of the small lathe, but when it is installed below the large lathe, the swarf is Because it is wide and falls in large quantities, it is necessary to install multiple screw conveyors in parallel in a direction where the screw shafts are perpendicular to the main axis direction of the large lathe. It is necessary to form a single chute with a wide width and a corrugated cross section, and to connect a swarf delivery tube to the end of the chute, that is, the discharge port of the screw conveyor, for guiding the swarf to the swarf storage surface. When a swarf delivery tube with a flat bottom is connected to a chute with a corrugated cross-section, fine swarf such as casting scraps are suddenly removed from the gutter-shaped chute with a flat bottom near the discharge port of the screw conveyor. As the cuttings reach the entrance of the cuttings delivery tube, the thrust is lost at certain points, causing them to stagnate and become clogged.

In addition, if each screw conveyor is provided with a separate delivery tube, this purpose can be achieved in the case of casting chips, but with a general-purpose machine tool, it is necessary to cut steel as well, and in that case, the side In many cases, the curled shavings carried out by the various screw conveyors are intertwined with each other and become a single piece, so it is not possible to separate them and send them out to the respective production tubes.

Therefore, the present invention is a cutting swarf that can send out both casting scraps and iron scraps, which is characterized by having a corrugated lower part of the delivery tube suitable for sending out casting swarf, and connecting the upper part of each delivery tube so that they are integrated. It provides a delivery tube.

An embodiment of the present invention will be described below in detail with reference to the drawings.A plurality of chutes for receiving cutting chips are connected in a wave-shaped cross section and extend diagonally upward on the outer wall of the chute 1 at both ends.

A screw shaft 3 with a spiral conveyor blade 2 implanted in each chute 1 is rotatably installed horizontally, a screw conveyor 4 is installed, and a sprocket (not shown) is fixed to the tip of each screw shaft 3. The chinos 5 are hung in a corrugated manner so that the adjacent screw shafts 3 rotate in opposite directions, and the chinos 5 are hung on the sprocket 7 of the drive motor 6.

As shown in FIG. 3, a bottom plate 8 having a shape similar to the wavy cross-sectional shape of the chute 1 and a flat top plate 9 are connected to each of the discharge ports of a plurality of chutes 1 to form an integrated delivery system. A swarf delivery tube 10 having a space is formed into a swarf delivery tube 10 having an upwardly curved and raised shape as shown in FIG.

11 is a machine tool such as a lathe, and 12 is a baffle plate provided at the peak of the chute 1 to prevent curled iron scraps from co-rotating with the screw shaft 3.

In the present invention, since the cuttings are cut in this way, if the cuttings are casting scraps, the cross-sectional shape of the bottom plate 8 of the cuttings delivery tube 10 has a waveform similar to the cross-sectional shape of the discharge port of the chute 1, so that the cuttings are removed by the screw conveyor 4. The fine casting scraps subjected to thrust are guided from the discharge port of the chute 1 to the bottom plate 8 and sent to the cutting scrap delivery tube 10.
It is smoothly delivered to the opening and does not stagnate near the discharge port.

In addition, if the shavings are curled iron shavings, the swarf delivery tube 10
can be easily discharged through the delivery space surrounded by the bottom plate 8 and top plate 9.

In this way, the shape of the bottom plate 8 of the swarf delivery tube 10 is a corrugated shape that can send out fine shavings of castings, etc., and curled iron shavings can be easily discharged through the delivery space surrounded by the bottom plate 8 and the top plate 9. It is characterized by the fact that it can be used commonly for sending out casting scraps and iron scraps, and therefore, there is no need to replace the cutting swarf delivery tube as appropriate for each different type of workpiece, so production efficiency is significantly improved.

Although the cross-sectional shape of the bottom plate 8 is formed into a gradually shallower waveform on the opening side of the chip delivery tube 10, the waveform on the opening side may also be the same as the waveform on the side connected to the chute 1.

As described above, the present invention is a useful device that can be used commonly regardless of the type of cuttings, has a simple and robust structure, and is easy to manufacture.
