Description

The present invention includes a cutting powder removing device that removes cutting powder generated when a workpiece is machined using a machine tool from a tool, a height adjusting member incorporated in the cutting powder removing device, and the cutting powder removing device. The present invention relates to a machine tool and a method for manufacturing a turbine.

  2. Description of the Related Art Broaching has been known as a method for machining a groove having a predetermined shape on an inner peripheral surface or surface of a workpiece with high accuracy and high efficiency in the axial direction of the workpiece. In this broaching process, an axial tool called a broach, which has a large number of cutting edges (cutting parts) that gradually increase in size from the front end side toward the rear end side, is pressed against the inner peripheral surface or surface of the workpiece. However, it is possible to process a groove according to the outline of the broach by pulling out or pushing in.

  Since the broach cuts a workpiece, cutting powder is generated during the machining. And since the cutting edge of the broach is formed in multiple stages in the axial direction, the cutting powder may adhere in a curled state in the cutting groove (chip pocket) between the cutting edges immediately after cutting. . In this way, if chips adhere to the inside of the blade groove, it is not only possible to form an accurate groove when the next groove is processed, but the cutting edge (blade groove) and the work surface of the workpiece may be damaged, There is a risk of peeling on the surface.

Therefore, conventionally, there has been provided a cutting powder removing device that removes cutting powder adhered in the blade groove by rubbing the brush against the broach. In addition, when cutting a workpiece having several tens of machining points, it is necessary to automate by installing a cutting powder removing device in-line in order to perform continuous machining.
As such a conventional cutting powder removing device, for example, a brush installed on a tool path of a broach cutter described in Patent Document 1 is known.

  The roller 17 is attached to the other surface of the base portion 15 along the longitudinal direction of the base portion 15, and is a member that functions like a so-called roller follower. Specifically, the roller 17 is attached to a position where the working surface 14 of the height adjustment block 10 attached to the tool table 3 can contact and travel when the tool table 3 advances. In other words, the roller 17 is disposed so as to ride on the working surface 14 of the height adjustment block 10 when the tool table 3 travels in the traveling direction, and the roller 17 corresponds to the distance of the working surface 14 from the broach 5. The position of the (nozzle unit) changes.

The air nozzle 16 has a cylindrical main body 18 and nozzle holes 19 formed at regular intervals along the longitudinal direction of the main body 18. The air nozzle 16 is fixed to the base portion 15 so that the longitudinal direction is along the traveling direction. Further, the nozzle hole 19 is directed so that air is blown onto the cutting edge portion 8 when the tool table 3 has traveled to the position of the cutting powder removing device 6 (see FIG. 3).
An air pipe 20 is connected to the air nozzle 16 so that air is supplied from a compressed air supply device such as a compressor (not shown).

  Here, the relationship between the cutting edge portion 8 of the broach 5 and the operation surface 14 of the height adjustment block 10 will be described in detail. As described above, the first surface 21 and the second surface 22 of the cutting edge 8 of the broach 5 are inclined so as to be separated from each other toward the rear in the inclination traveling direction. The working surface 14 of the height adjustment block 10 is an inclined surface having an inclination angle corresponding to this inclination, and a roller 17 travels on the working surface 14, whereby the air nozzle 16 and the first surface of the cutting edge portion 8. It is formed so that the relative position to 21 is constant.

  Note that the shape of the working surface 14 is not limited to the shape described above. That is, the air nozzle 16 and the cutting blade of the broach 5 need not be formed so as to have a constant relative position. For example, at the position corresponding to the rough cutting blade, that is, at the front side in the traveling direction, the air nozzle 16 It is good also as a shape which brings the broach 5 closer. In other words, the working surface 14 may not be linear, and may be formed so as to reduce the distance between the air nozzle 16 and the broach 5 at a position where cutting powder is likely to adhere. Further, the operating surface 14 does not need to have a smooth shape, and may have a stepped shape, for example.

A fitting groove is formed in the workpiece W by a plurality of cutting blades of the broach 5. The broach 5 that has worked on the workpiece W travels as it is by the endless chain 4 and is introduced into the place where the cutting powder removing device 6 is disposed.

In removing the cutting powder, first, the roller 17 rides on the height adjustment block 10 that travels with the tool table 3. As the roller 17 travels on the working surface 14 of the height adjustment block 10, the air nozzle 16 gradually moves away from the broach 5. The distance between the broach 5 and the air nozzle 16 changes.
The height adjustment block 10 of the present embodiment follows the first surface 21 and the second surface 22 of the cutting edge 8, that is, the first surface 21 and the second surface 22 of the cutting edge 8 and the air nozzle 16. Therefore, the distance between the air nozzle 16 and the cutting edge 8 is kept constant. In other words, the distance between the cutting edge 8 and the air nozzle 16 that gradually increases the thickness in the vertical direction is displaced by the distance between the broach 5 and the air nozzle 16 according to the inclination of the first surface 21 and the second surface 22. It stays constant without getting close.

  And the cutting powder adhering to the cutting-blade part 8 is removed by injecting air (compressed air) from the nozzle hole 19. FIG. As shown in FIG. 3, the air is blown above and below the cutting edge portion 8.

According to the above embodiment, the height adjustment block 10 changes the distance between the broach 5 and the air nozzle 16 optimally according to the position of the cutting blade portion 8, and therefore follows the change in the shape of the cutting blade portion 8. Cutting powder removal force can be secured.
Moreover, since the cutting powder is removed in a non-contact manner by blowing air, it is possible to suppress deterioration of the removal force due to wear or the like.

In addition, since the height adjustment block 10 is used to guide the position of the air nozzle 16, the air nozzle 16 can be guided with a simpler configuration.
In addition, the height adjustment block 10 may be designed to follow the shape of the cutting edge portion 8 by forming the height adjustment block 10 so that the relative position between the cutting edge portion 8 and the air nozzle 16 is constant. Therefore, the design of the height adjustment block 10 corresponding to the shape of the cutting edge portion 8 is facilitated.

Moreover, by providing the cutting powder removing device 6 on each of the first surface 21 and the second surface 22 of the cutting edge portion 8, the cutting powder of the broach 5 having two surfaces facing opposite sides can be removed. .
Further, the two air nozzles 16 are installed so that their positions in the traveling direction are different, so that it is possible to prevent the flow of air ejected from the plurality of air nozzles 16 from being obstructed.

They are arranged side by side.

  Next, an example of the operation of the gas turbine 100 will be described. The air taken in from the air intake port 105 of the compressor 101 passes through the plurality of compressor stationary blades 107 and the compressor moving blades 108 and is compressed into high-temperature / high-pressure compressed air. In the combustor 102, a predetermined fuel is supplied to the compressed air and burned, whereby high-temperature and high-pressure combustion gas is generated. The combustion gas passes through the turbine stationary blade 110 and the turbine rotor blade 111 of the turbine 103, thereby rotating the rotor 104. Power is generated by applying power to the generator connected to the rotor 104.
