Although the plate thickness is also increased, there is a problem that increasing the thickness of the sealing material increases the frictional resistance and puts an extra load and burden on sliding parts of equipment such as machine tools. In addition, since the sealing mechanism becomes large, there is a disadvantage that the sealing material cannot be attached to the sliding portion of the device which has a small space.

Further, when a sealing material made of rubber or synthetic rubber is solidified by heat, friction or the like and loses elasticity, if some variation occurs in a sliding portion or a sliding surface of a machine tool or the like, Due to the elasticity of the sealing material, these fluctuations cannot be covered and there is a drawback that the fluid sealing property and the wiping property deteriorate.

Further, in recent machine tools and the like, oils and chemicals are often treated, and in the case of a sealing material made of rubber or synthetic rubber, deterioration due to oils and chemicals is rapid, and the sealing material is Not only must be replaced frequently, but also when the sealing material is
In some cases, there were drawbacks associated with disasters.

The sealing member 1 made of a thin metal plate has a plate thickness of 0.01 to 0.3 mm, although it has an appropriate shape according to the shape and size of the sliding portion 3 of the device 2 and the sliding surface 5 of the device 2. Therefore, the contact area with the sliding surface 5 of the device 2 is small, the frictional resistance is also small, no extra load or load is applied to the sliding part of the device 2, and the drive power of the device 2 is not applied. There is.

The upper part 1 of the sealing material 1 made of a thin metal plate
a is attached to the sliding portion 3 of the device 2 with the screw 4, and the tip of the lower portion 1b of the sealing material 1 made of a thin metal plate is lightly pressed against the sliding surface 5 of the device 2 to slide.

May be directly attached to the sliding part 3 of the device 2 such as a machine tool, but the upper part 1a of the sealing material 1 made of a thin metal plate is firmly fixed by the fixing plate 6 and the sliding part 3 of the device 2 is firmly fixed by the screw 4. May be attached. By doing so, the precision of the fluid sealing property and the wiping property of the sealing material 1 made of a thin metal plate used for the sliding portion 3 of the device 2 is improved, and it is possible to use it more stably for a long period of time. be able to.

Further, as shown in FIG. 2, a protect cover 7 is attached to the outside of the sealing material 1 made of a thin metal plate of the present invention, and chips, stones and the like existing on the sliding surface 5 of the device 2 are caught. Damage or damage to the seal material 1 caused by an object colliding with the seal material 1 may be prevented.

The sealing material 1 made of a thin metal plate has a thickness of 0.01
.About.0.3 mm is suitable, and preferably 0.05 to 0.
It is preferable to set the thickness to 1 mm, and if the plate thickness exceeds 0.3 mm, the physical strength of the sealing material 3 becomes strong, but it is unsuitable due to difficulty in elasticity, and the plate thickness is less than 0.01 mm. Therefore, the sealing material 1 made of a thin metal plate is not suitable because the elasticity of the sealing material 1 becomes weak and the physical strength also becomes difficult.

As the material of the sealing material 1 made of a thin metal plate,
In addition to the spring stainless steel mentioned above, hardened ribbon steel,
Any thin plate of metal having high elasticity and physical strength, such as sub-zero hardening type stainless steel and berym copper, may be used. The fixed plate 6 and the protect cover 7 may be made of the same material as the sealing material 1 made of a thin metal plate, or may be made of a general steel material.

Further, as shown in FIG. 3, the metal thin plate sealing material 1 is bent in an inverted shape with the upper part 1a and the lower part 1b of the metal thin plate sealing material 1 as boundaries.
The upper portion 1a of the sealing material 1 is attached to the sliding portion 3 of the device 2 directly or via the fixing plate 6, and the tip of the lower portion 1b of the sealing material 1 made of a thin metal plate is attached to the sliding surface 5 of the device 2. You may comprise so that it may press and slide.

In the case of FIG. 3, since the seal material 1 is bent in an inverted V shape, it is possible to impart appropriate and stable elasticity to the seal material 1 and slide the seal material 1. It is possible to improve the accuracy of fluid sealing property and wiping property while suppressing the frictional resistance at the time. Although not shown, the sealing material 1 may be bent in a V shape.

You may comprise so that it may press 5 and may slide.

In the case of FIG. 4, a sealing material 1 made of a thin metal plate is used.
Of these, the tip portion 1a having a V-shaped curve is very short, but it is pressed against the sliding surface 5 of the device with a strong force and has a very strong elasticity as a sealing material, that is, a strong force. It has a fluid sealing property and a wiping property, and further, the leading edge part 1a follows the part 1b of the metal thin plate sealing material 1 located on the inner surface of the part where the tip of the fixing plate 6 is bent inward, Since the portion 1B of the sealing material 1 made of a thin metal plate is elastic and is separated from the inner side of the fixed plate 6 to form a curved curve, the movement of the tip portion 1B is prevented. It acts as a shock absorber, absorbs the load and load applied to the leading edge 1a, reduces the frictional resistance of the leading edge 1a, and imparts extremely strong elasticity and stability to the sealing material.

Attach the rectangular rubber plate seal material to the scraper of the separately provided chip transport trough, as in the case above, and attach the bottom end of the rubber plate seal material to the sliding surface. Pressure of 1 kg (width 10
The scraper of both devices was moved at a speed of 60 m / sec to convey the coolant waste liquid containing cutting chips.

When the coolant waste liquid containing the cutting chips was conveyed by the scraper as described above, in the case of the sealing material made of a thin metal plate of the present invention, even after 3 years, the chips and the coolant waste liquid were discharged. The sealing and wiping properties were not affected, and the sealing material was not worn or deteriorated, and the desired transfer efficiency was maintained. However, in the case of the known sealing material made of a rubber plate of the comparative example, after one year, the sealing material is abraded by cutting chips, deteriorated by friction and deteriorated by the coolant, and a smaller amount than the sealing material is used. Leakage of powder and coolant waste liquid, which may affect the sealing and wiping properties,
The desired transfer efficiency could not be maintained.

Further, when the thin metal sheet sealing material of the present invention is used, since the contact area with the inner surface of the chip transport trough, which is the sliding surface, is small and the friction resistance is small, a motor for driving the scraper is used. The electric power cost can be reduced by 50% compared to the case of the known sealing material made of a rubber plate of the comparative example, and the scraper of the sliding mechanism has no load or burden, so that no failure occurs.

Further, in the case of the known rubber plate seal material of the comparative example, it is necessary to replace the seal material every year, but in the case of the metal thin plate seal material of the present invention, 5 It is only necessary to replace the sealing material every year, which significantly improves the efficiency of chip transportation work, and because the frequency of replacement of the sealing material is low, maintenance work is less time consuming and the floor of the factory and the factory floor is soiled. There was no danger or disaster.
