Description

[Detailed Description of the Invention] The present invention relates to a chip removal device, and more specifically, the present invention relates to a chip removal device that prevents chips generated during cutting from getting entangled with a cutting tool (hereinafter referred to as the blade) and its surroundings. It is related to the device.

FIG. 1 is a schematic diagram of a cutting device showing how chips generated by conventional cutting become entangled with the cutting tools, and 1 and 2 are the cutting tools that perform the cutting, which are held in tool rests 3 and 4, respectively. .

To perform cutting, a drive source (not shown) causes the cutter and tool rest to approach the cut workpiece (not shown) and start cutting (in the direction of arrow A), and when the cutting is finished, the cutter and tool rest retreat to their original positions (arrow B). Direction) The machine is set up as if waiting for the next cutting process.

However, since the machined product rotates during cutting, the chips 5 generated during the cutting process become entangled with the cutter, the holder, etc., and cannot be easily removed, thereby hindering the subsequent cutting process.

As a result, the operator must constantly monitor and remove chips entangled with the cutter, etc., resulting in major drawbacks such as an increase in the number of man-hours required for cutting.

This invention was developed to eliminate these drawbacks, and was devised to prevent the chips generated during cutting from getting entangled with the cutter, and at the same time to completely remove the entangled chips. The present invention provides a chip removal device that is manufactured using the following methods.

The present invention will be explained in detail below based on the drawings.

Figures 2a, b, and c show an embodiment of the present invention, in which a is a plan view, b is a front view, and C is a right side view.

In each country, 11 and 12 are blades arranged adjacent to each other, 13 and 14 are turrets that hold the blades 11 and 12,
Reference numeral 15 is a chip removal cover (hereinafter referred to as a cover) that has a hole that matches the size of the cutter and has a shape that allows the cutter to protrude from the hole, and is shaped to surround parts other than the cutter necessary for cutting. ), 16a and 16b are fixed to the knife 15 and support the knife 15, and are driven in the axial direction of the blades 11 and 12 (in the direction of arrow A) by a drive source (not shown).
This is a connecting rod that reciprocates the cover 15 along the direction B), but it may be integrated with the chip removal cover 15.

17 is a first exhaust mechanism attached to the inside of the cover 15, and 18 is an air supply port for supplying compressed air of the first exhaust mechanism 17, which is connected to a compressed air sending machine (air compressor) not shown. Ru.

Reference numeral 19 indicates an air outlet provided in the cover 15 in order to blow compressed air supplied from the air supply port 18 of the first exhaust mechanism 17 toward the cutting edge of the cutter 11.12 at an appropriate angle; A second exhaust mechanism 20 attached to the outside of the cover 15 is connected to an unillustrated compressed air delivery machine (air compressor) through an air supply port for supplying compressed air.

22 supplies compressed air supplied from the air supply port 21 of the second exhaust mechanism 20 to the blade 11. 12 is an air outlet for blowing air out at an appropriate angle toward the cutting edge, and 23 is chips entangled with the cutting tool.

Next, the chip removal operation will be explained.

When cutting starts, the cutter 11, 12 and the tool rest 1
3.14 approaches a cut workpiece (not shown) and performs cutting using a drive source (not shown).

During the cutting process, the cover 15 acts as a shield against the chips 23 and prevents them from getting entangled with parts other than the blades 11 and 12 protruding from the cover 15.

Furthermore, during the cutting process, the compressed air supplied from the air supply ports 18 and 21 of the first and second exhaust mechanisms is blown out from the air outlet 19.22 toward the cutting edge, thereby blowing off the chips 23 and hitting the cutting edge. Prevent entanglement.

After the cutting process is completed, the blades 11, 12 and the turret 13,
14 is retreated to the position before cutting by a drive source (not shown), and many of the chips 23 are removed by compressed air, but they are not blown away and are removed by the blades 11, 1.
The chips 23 entangled in the cutter 11.2 are removed from the cover 15 via the connecting rods 16a, 16b by a drive source (not shown).
The above-mentioned tangled chips 23 are directly removed by moving the cutting tool 12 in the direction of the cutting edge (in the direction of arrow A) so as to protrude somewhat in front of the cutting edge.

At the same time, air outlet 19. Since compressed air is blown out from 22 and used in conjunction with the removal method by reciprocating the cover 15, the entangled chips 23 can be completely removed.

As explained above, according to the present invention, chips generated during cutting can be prevented from getting entangled with the blade and its surroundings,
Since entangled chips can be completely removed automatically, there is no need to arrange a working shell, and there are great advantages such as the reduction of man-hours due to unmanned cutting.
