Description

[Detailed description of the invention] The present invention provides a cutting machine that uses cutting fluid.
The present invention relates to a cutting fluid supply device.

When cutting steel materials and nonferrous metals, it is necessary to supply an appropriate amount of cutting fluid to reduce wear on the circular saw blade edge, prevent breakage, improve cutting efficiency, and improve the cutting surface.

In conventional cutting machines, a discharge port is provided in the circular saw cover so that the cutting fluid discharged near the cutting edge of the circular saw blade is supplied to the cutting section via the circular saw blade. Since the discharge port is provided at a fixed position, depending on the size of the workpiece, it may be impossible to supply an appropriate amount of cutting fluid to the cutting section. In other words, the cutting fluid discharged near the cutting edge of the circular saw blade flows downward due to its own weight, but when the workpiece is large, the cutting position of the circular saw blade changes, so the cutting fluid discharges from the circular saw blade before reaching the cutting part. Due to the rotation of the blade, most of the cutting fluid may flow out in the direction of rotation.

Therefore, a method for supplying an appropriate amount of cutting fluid to workpieces of different sizes has become an issue.

The purpose of this invention is to prevent damage to the circular saw and cutting of the workpiece due to the inability to provide cutting fluid to the area where the circular saw processes the workpiece, depending on the type and size of the workpiece. The goal is to eliminate negative effects such as deterioration of surface finish and reduction in work efficiency.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a base, 2 is a fixed vise for fixing the work material, 3 is a moving vise, 4 is a circular saw, 5 is a circular saw 4
6 is a circular saw cover that covers the circular saw 4; 7 is a pump that provides cutting fluid; 8 is a circular saw cover that covers the circular saw 4;
is an electric motor, 9 is a kettle that adjusts the amount of cutting fluid, 10
is a tube, 11 is a tube connector that fixes the tube 10, 12 is a nut that fits into the tapered screw part of the tube connector 11, 13 is a spring, and 14 is pressed by the spring 13 and protrudes into the positioning hole 16 of the circular saw cover. A fixing member for inserting and positioning the part 17, 15 is a spring 13
It is a spring stopper that prevents it from coming off. Reference numeral 18 indicates an arc-shaped long hole on the side surface of the circular saw cover.

With the above configuration, by pulling the fixing member 14 in the direction of arrow B as shown in FIG. 5, the protrusion 17 provided on the fixing member 14 comes out of the hole 16 of the circular saw cover 6, and the positioning is released. In this state, the tube connector 11 can be moved to any position on the elongated hole 18. 2 and 4 show a state in which the protrusion 17 of the fixing member is inserted into the positioning hole 16 shown in the circular saw cover 6 and positioned by performing the operation shown in FIG. 5.

In this example, an arc-shaped elongated hole was explained.
When using a flexible tube, it is not limited to an arc shape. Furthermore, the tip of the tube can be directly inserted and fixed into a hole provided at an arbitrary position without using an elongated hole or the like.

Furthermore, although this embodiment describes a cutting machine with a circular saw cover, even if there is no cover, the base of the rigid tube supported on the main body can be supported by a rotatable connector, and a fixing means can be attached to this. If provided, the same purpose can be achieved.

According to the present invention, the tube for supplying cutting fluid can be changed from a fixed position to an arbitrary position using the elongated hole provided in the circular saw cover as a guide, and the positioning means includes a spring attached to the fixing member. As a result, the protrusion provided on the fixing member is press-fitted into the positioning hole provided on the circular saw cover, which prevents cutting fluid from being supplied to the blade, and prevents damage to the circular saw and damage to the workpiece. It has excellent practical effects in that it can prevent adverse effects such as deterioration of the cut surface and reduction in work efficiency, is resistant to vibrations generated during cutting work, and can extremely easily set the position of the tube.
