DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for easily removing chips generated during a cutting operation by a thread sawing machine.

[0002]

2. Description of the Related Art As is generally known, swarf generated during a cutting operation by a thread sawing machine covers a scribe line of a work material, and makes it difficult to see the positional relationship between the thread saw tooth and the scribe line, resulting in an unexpected direction. Work efficiency was reduced.

As a method for solving this problem, a blade is attached to one end of a motor shaft of a thread sawing machine body, a wind is generated, the air is blown out near the thread sawtooth with an air hose passing through an arm, and chips are scattered and removed (Ryobi Co., Ltd.). TF-540
0).

[0004] From the upper surface of the thread saw machine table, near the thread saw teeth,
A first discharge tube that passes through the inside of the material holding portion and an adjusting rod that adjusts the height of the material holding portion and that exits the thread sawing machine body,
Furthermore, a method of connecting a hose of an electric vacuum cleaner to a second discharge tube that passes through the lower surface of the table, near the jig saw teeth and out of the main body of the jig saw through the lower surface of the table, and suctions and removes chips.
(Registered Utility Model No. 3028076).

[0005] A method in which a large dust collector is installed in a processing specialized factory to collect and remove swarf from all machines in one place.

[0006] Other commonly performed workers,
There is a method of performing work while squirting and removing with your own mouth.

[0007]

The method of blowing out the first wind to scatter and remove cutting chips is incorporated in a thread sawing machine body, a blade is attached to one end of a motor shaft, and an air hose is provided in an arm. The production cost increases, and the amount of air sent and the wind force are large, so the chips may be blown to the workers, and there is a risk that the fines of the chips may enter the mouth and eyes of the workers. In addition, since the blowing direction of the wind and the position at which the wind hits the work material are fixed, the wind speed corresponding to the cutting speed, the size of the scattered area of the cutting powder, the scattering position, etc., due to the difference in the material of the work material Direction,
The position of the wind and the strength of the wind cannot be adjusted.

A method of sucking and removing from the upper and lower surfaces of the table from the vicinity of the second thread saw blade using a discharge tube is also incorporated in the thread sawing machine main body, and a suction hole is formed in the material holding portion and the adjusting rod. The production cost is high, such as making the machine. Furthermore, after the power of the thread sawing machine is turned off, the power of the vacuum cleaner is turned off with a slight delay, which also increases the manufacturing cost. The method requires more power than the method of moving by blowing, and the power consumption of the vacuum cleaner connected to the outside needs to be large, and the operation noise is also large.

The method of installing and removing a large-sized dust collector in a third processing specialty factory is a facility that can be used only in a specialty factory, and cannot be easily installed in a small factory, a private factory, or a general household due to cost and installation location problems.

[0010] The fourth worker, a method of working while blowing away with his own mouth, also removes fine chips because the face is brought close to the thread sawing machine when blowing chips, and the face of a machine part that moves up and down In addition, there is a risk of hitting, and when working for a long time, not only is the mouth tired, but it may cause dizziness, which is harmful to health and not good for the body.

Focusing on the above, the present invention blows a wind for removing chips generated at the time of a cutting operation with a thread sawing machine from the operator side toward the thread sawing machine, and removes chips from the mouth and eyes of the operator. In addition to preventing fine powder from entering, the direction of the wind, the position where the wind hits, and the strength of the wind By making the adjustment possible, the positional relationship between the thread saw tooth and the scribe line becomes easier to see, and as a result, the work efficiency can be improved.

Still another object is to provide a thread sawing machine having a height adjusting rod of a material holding portion without being built in the thread sawing machine main body.
It is an object of the present invention to provide a swarf removal device for a thread saw machine which can be attached to all.

Still another object is to provide an apparatus for removing chips from a thread sawing machine which does not require a vacuum cleaner having a large power consumption.

Still another object of the present invention is to provide an inexpensive, easy-to-use, detachably attachable and removable thread sawing machine for a thread sawing machine in a small factory, a private factory, and a general household. It was done.

Still another object is that there is no danger of bringing the face close to the machine to remove the chips, and even if the cutting work is performed for a long time, the worker does not blow with his / her own mouth, so that the mouth becomes tired. SUMMARY OF THE INVENTION It is an object of the present invention to provide an apparatus for removing chips from a thread sawing machine, which does not cause dizziness.

[0016]

The main object of the present invention is to attach a clamping device at a lower end of an adjusting rod and close to a material holding portion, and allow a person to apply a force to the clamping device to deform the clamping device. A support part made of a material that has the property of maintaining the deformed shape even if it is removed is attached with a holding bracket and screws,
This is attained by attaching an air tube to the support portion, and making the tip of the air tube slightly protrude from the tip of the support portion.

Since the air tube is attached to the supporting portion, the tip of the air tube is slightly protruded to prevent direct contact between the thread saw tooth and the front end of the supporting portion.
The safety is improved, and the tip of the air tube is easily directed to the direction and the position where the wind is required.

Further, the support portion can be deformed by applying a force by a human, and is made of a tube made of a material having a property of maintaining the deformed shape even when the force is removed. It can also be connected to the air tube on the arm side of the fitting.

Another object is achieved by attaching the other end of the air tube along an arm of a thread sawing machine and connecting the other end to a small air pump.

The capacity of the small air pump to be used is such that it does not need to be strong enough to scatter chips over a wide area during the cutting operation, and the chips corresponding to the relative speed at which the thread saw blades advance are used. Achieve the purpose sufficiently with the ability to dissipate so that the marking lines can be seen.
