Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the prevention of chips from being scattered by a cutting machine for preventing chips generated during cutting from scattering.

[0002]

2. Description of the Related Art A conventional technique will be described with reference to FIG. Chips generated when cutting the workpiece 13 are fixed to the side of the support 4 installed behind the base 1 at a position located behind the cutting grindstone 7.

[0003] With the chip guide plate 9 as a guide, it scatters to the rear of the main body, enters through an opening of a chip receiving box 10 detachably provided behind the chip guide plate 9, and enters inside the chip receiving box 10. I was getting stuck.

[0004]

The conventional chip scattering prevention device of a cutting machine has a chip receiving box for collecting chips which are generated at the time of cutting. This is a state in which wind is also blown into the chip receiving box together with the chips by the wind generated by the rotation. Since the blown air has no place to escape, the air pressure inside the chip receiving box rises and blows out from the opening of the chip receiving box. In this case, there is a problem that small chips are blown out together and the accumulated chips are scattered above the base and around the main body by wind pressure. Accordingly, it is necessary to remove the chips accumulated above the base each time the cutting is performed, which is troublesome. Further, after the work was completed, cleaning was difficult because the chips were scattered over a wide area.

An object of the present invention is to solve the above-mentioned problems of the prior art and to improve cutting workability by making it easier for chips to collect in a chip receiving box.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to provide a movable vice for fixing a material to be cut and a base on which a fixed vise is installed and a shaft engaged with a support provided at the rear of the base as a fulcrum, and are swingable. A chip guide plate that has an arm and a cutting grindstone held in a side surface of the support table, and guides a scattering direction of chips scattered at the time of cutting behind the cutting grindstone,
In a cutting machine having a chip receiving box for collecting the chips, at the time of metal working, a ventilation opening for reducing a pressure rise in the chip receiving box due to a wind including the chip generated by the rotation of the cutting grindstone is provided in the chip receiving box. Achieved by providing them in place.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. 1 is a right side view of the cutting machine, and FIG. 2 is a right side view of FIG.

In FIG. 1, a movable vise 2 and a fixed vise 3 for fixing a workpiece 13 are mounted on a base 1. A support 4 is fixed to the upper rear of the base 1, and an arm 6 is slidably supported by a shaft 5 engaged with the support 4 as a fulcrum. A cutting grindstone 7 for cutting the workpiece 13 and a protective cover 8 that covers the cutting grindstone 7 are attached to the arm 6.

A swarf guide plate 9 for guiding swarf scattered at the time of cutting (in the direction of the arrow in the figure) is fixed to the side surface of the support base 4 and behind the cutting grindstone 7, and a base in the figure in the swarf scattering direction. 1
A chip receiving box 10 having an opening at a position to be engaged with the chip guide plate 9 at the rear side is detachably provided on the chip guide plate 9 with a wing bolt 12. Although the chip receiving box 10 is covered on the opposite side to the opening in the chip scattering direction, one or more small ventilation holes 11 (8 in this embodiment) are provided on the left side in the orthogonal direction. ) Is provided at a position above the base 1.

In the above configuration, the cutting operation is performed on the material to be cut 1.
3 is fixed by the moving vise 2 and the fixed vice 3, and the arm 6 is moved downward to be cut by the rotating cutting grindstone 7. At the time of cutting, chips are generated, and the chips are blown off by wind generated by rotation of the cutting grindstone 7. The blown chips are blown to guide the chip guide plate 9 located behind the cutting whetstone 7,
It accumulates in the chip receiving box 10. At this time, the air blown into the chip receiving box 10 together with the chips is provided in the chip receiving box 10. It flows toward the ventilation opening 11 (in the direction of the solid arrow shown in the figure). Here, the chips are placed on the rear side surface 10 of the chip receiving box 10.
a (in the direction of the dotted arrow in the figure), and falls downward. Although wind is generated every time the cutting operation is performed, even if the air is blown into the chip receiving box 10, the dust flows out of the ventilation port 11, so that the chips accumulated in the chip receiving box 10 do not fly up and scatter. After the work is completed, the wing bolt 12
If you loosen, the chip receiving box 10 can be pulled out backward,
Chips can be easily discarded, and cleaning is completed in a short time.

[0011]

According to the present invention, the chip receiving box for storing chips generated at the time of cutting is provided with a ventilation hole for air blown together with the chips, so that the chips can be collected by the rise in air pressure. Can be prevented from being scattered from the swarf, swarf can easily accumulate, and cleaning after work can be easily performed. In addition, since chips do not jump out of the opening of the chip receiving box and accumulate on the base, there is no need to remove chips from the base each time cutting is performed, and work efficiency is improved.
