Description

  The present invention relates to a disk-shaped component processing apparatus that obtains a disk-shaped component by shearing a plate-shaped material.

  Various methods are conceivable as a method of obtaining a disk-shaped part by subjecting a plate-shaped material to a circular shearing process. For example, in Patent Document 1, in order to prevent so-called burr formation and obtain a circular cut material, a pair of opposing punch deformation processes that perform a punch deformation process on a circular cut part of the cut material Disclosed is a plate material circular cutting device including a body and a pair of opposing push-back processed bodies that separates a portion to be cut by pressing back the punch-deformed portion formed by the punch-deformed portion in the reverse direction. ing. In this plate material circular cutting device, the material to be cut held in the transfer section is rotated, the material to be cut is sheared by a punching deformed body disposed on the machine base, and the punching deformed portion is formed by a push-back processed body. The material to be cut is cut into a circular shape by pushing back in the reverse direction.

  Patent Document 2 discloses a curved shearing machine that smoothly curves and shears the edge of a continuously supplied thin steel strip with the steel strip stopped at the tip or tail edge.

However, when performing shearing by rotating the material to be cut (plate-shaped material) as in Patent Document 1, the material that can be used as the plate-shaped material is limited to a shape close to a square. Moreover, in the said patent document 2, a pair of upper and lower rotary blades are made to oppose both surfaces of a steel strip, and a shearing process is performed. Therefore, in order to process a disk-shaped part, after separating a pair of upper and lower rotary blades, a mechanism that again faces both surfaces of the steel strip is required, which complicates the apparatus and is not excellent in productivity. .
Moreover, in patent document 1, 2, only shearing is performed and the device for performing a punching process with this is not disclosed at all.

As shown in the figure, the rotary blade 4 receives a pressure force in the downward direction H1 and moves in the circumferential direction C while rotating in the idling direction Q itself. In addition, since the rotary blade 4 moves in the circumferential direction C while moving in the downward direction H1, the circular movement locus of the cutting blade 411 in the rotary blade 4 becomes an inclined line L.

As shown in FIG. 1, on the outer peripheral side of the punching punch 5 and on the inner peripheral side of the rotary holder 3, a pressing holder 6 for pressing and holding the plate-shaped material 80 against the die 2 is provided on the rotary holder 3.

Further, in the punched disk-shaped component processing apparatus 1 of this example, the punching processing and the rotary blade by the punching punch 5 are performed in a state where the pressing holding portion 6 presses the plate material 80 against the urging force of the spring 64. 4 is configured to perform a shearing process.

In the punched disk-shaped component processing apparatus 1 of this example, the pressing holding unit 6 presses the plate-shaped material 80 disposed on the die 2, and then the punching punch 5 performs punching processing, and then a plurality of The rotary blade 4 is configured to perform a shearing process. The perforated disk-shaped component processing apparatus 1 of this example performs punching by the punching punch 5 when the rotary spindle 11 operates for one stroke to generate a pressing force, and positions the plate-shaped material 80 by the punching punch 5. In such a state, shearing is performed by a plurality of rotary blades 4 that have received the rotational force of the rotary spindle 11.
In the perforated disk-shaped component processing apparatus 1, each support holder 31 that supports the rotary blade 4 can be adjusted in conjunction with each other in the radial position with respect to the rotation center axis C <b> 2 of the rotary holder 3. it can. Thereby, the perforated disk-shaped part processing apparatus 1 can be adapted to the processing of the perforated disk-shaped part 8 having a disk shape with various outer diameters.

Next, the procedure and effect of processing the drilled disk-shaped component 8 by the drilled disk-shaped component processing apparatus 1 of this example will be described.
In processing the perforated disk-shaped component 8, first, as shown in FIG. 1, a part (end portion) of a plate-shaped material 80 as a steel strip wound as a coil material is disposed on the upper surface of the die 2. . Next, the entire rotary holder 3 is lowered relative to the die 2 by the moving operation of the rotary spindle 11 (approaching the die 2).
At this time, as shown in FIG. 2, the lower end surface of the pressing holding portion 6 is first brought into contact with the plate-like material 80 disposed on the die 2, and the pressing holding portion 6 is drawn into the rotary holder 3 while elastically deforming the spring 64. It is. Then, the plate-shaped material 80 is pressed against the die 2 by the pressing holding unit 6 that receives the urging force of the spring 64 and is held so as not to move from the die 2.

  As shown in FIG. 3, when the rotary holder 3 is further lowered by the moving operation of the rotary spindle 11, the punching punch 5 comes into contact with the plate-shaped material 80. Then, the punching punch 5 receiving the pressure of the rotating main shaft 11 presses the plate-shaped material 80 against the die 2 and shears a part of the plate-shaped material 80 to the punching hole 22 of the die 2 to perform the punching process. Thereby, a center hole 81 having a shape along the cross-sectional shape of the punching punch 5 is formed in the plate-shaped material 80. And the state by which the punching punch 5 was inserted in the center hole 81 of the plate-shaped raw material 80 is maintained. Note that the scrap 82 generated by the punching process can be taken out after being dropped into the punching hole 22.

Next, immediately after the punching process is performed by the punching punch 5, the rotation of the rotary holder 3 is started by the rotation operation of the rotary spindle 11. At this time, the rotary holder 3 can rotate relative to the punching punch 5 and the pressing holding portion 6 via the bearings 32 and 33.

At this time, the plurality of rotary blades 4 circulate while rolling on the surface of the plate material 80 along the outer periphery of the outer peripheral blade 21 in the die 2. Further, in this example, in order to reduce the load on the apparatus, the plurality of rotary blades 4 are moved around the outer periphery of the outer peripheral blade 21 a plurality of times to perform shearing.

  As a result, as shown in FIGS. 6 and 7, the plate-shaped material 80 is gradually sheared by the plurality of rotary blades 4 and the outer peripheral blade 21 from the partial portion in the circumferential direction C of the outer peripheral blade 21 to the entire periphery. Processing is performed, and the disk shape of the holed disk-shaped part 8 can be processed. Therefore, the perforated disk-shaped part 8 can be processed with a small load, the configuration of the apparatus can be simplified, and the apparatus can be configured at low cost. Further, the punching process and the shearing process in this example can be performed by a one-stroke moving operation (lowering operation) of the rotating spindle 11. Thereby, the apparatus configuration can be further simplified.

In addition, after finishing the drilled disk-shaped part 8, the rotation of the rotary holder 3 can be stopped by stopping the rotary operation of the rotary spindle 11, and the rotary holder 3 can be raised by the raising operation of the rotary spindle 11. it can. At this time, the rotation operation of the rotary spindle 11 can be stopped while the pressing holder 6 is pressing the drilled disk-shaped component 8 after processing.

  Further, the disk-shaped shearing process of this example is performed in a state where the punching punch 5 is inserted into the center hole 81 of the plate-shaped material 80. Thereby, when performing a shearing process, the plate-shaped raw material 80 can be positioned by the punching punch 5, and the axial center between the center hole 81 formed by the punching process and the disk shape formed by the shearing process. Can be prevented from shifting. Therefore, it is possible to improve the processing accuracy of the holed disk-like component 8.

Moreover, since the drilling disk-shaped component processing apparatus 1 of this example performs the shearing process by rotating the rotary holder 3, the plate-shaped material 80 can have various shapes. In this example, a coil material formed by winding a steel strip is used as the plate-like material 80. Thereby, instead of arranging another plate-shaped material 80 every time the perforated disk-shaped component 8 is processed with respect to the plate-shaped material 80, a predetermined amount of coil material is fed out, and then the next hole is quickly formed. Processing of the bright disk-shaped part 8 can be started. Therefore, productivity for processing the perforated disk-shaped part 8 can be improved.
Therefore, according to the perforated disk-shaped component processing apparatus 1 of this example, plate-shaped materials 80 of various shapes can be used, punching and shearing are performed with a simple apparatus configuration, and the perforated disk is performed. The productivity of the shaped part 8 can be improved.
