When the operation button of the input unit 42 is operated, as the control unit 40 drives the fixed drive unit 46 to drive, the movable unit 25 moves to the fixed unit as the fixed cylinder 22 drives the cylinder shaft 24 forward. 21, the metal rod 50 is fixed by advancing toward 21 and being in contact with the fixing part 21 as shown in FIG.

Subsequently, the control unit 40 drives and controls the pressure driving unit 48 so that the molding jig 38 moves forward toward the metal rod 50 as the pressure cylinder 31 drives the cylinder shaft 32 forward. As described above, the switch rod 44a squeezed from the end of the metal rod 50 into the forming groove 37 to form the sensor 44 by the metal rod 50 is pushed in, so that the protrusion 44b of the switch rod 44a is removed. When the switch terminal 44f of the two switches 44d is pressed, the control unit 40 drives the pressure driving unit 48 so that the pressure cylinder 31 drives the cylinder shaft 32 backward. As described above, the forming jig 38 retreats to the initial initial position.

Thereafter, the control unit 40 drives the fixed drive unit 46 to control the fixed cylinder 22 to drive the cylinder shaft 24 backward so that the movable unit 25 retracts to the initial position to release the fixing of the metal rod 50. Done.

As described above, according to the first embodiment of the present invention, the end of the metal rod 50 can be processed to a desired diameter without the loss of raw materials.

Next, the metal rod processing apparatus according to the second embodiment of the present invention will be described in detail with reference to FIGS. 10 to 17.

And second distance measuring instruments 70 and 80 and pressing means 30.

Since the fixing means 20 is the same as the configuration of the first embodiment, a description thereof will be omitted.

Unlike the above-described first embodiment, the pressing means 30 does not have a sensor for detecting the degree to which the metal rod 50 enters into the forming groove 37 of the forming jig 38, and thus, of the jig holder 36. The fact that the reflecting plate 39 is provided on the side surface is different from that of the first embodiment described above.

The stopper means 60 is for setting the initial position of the metal rod 50, the rotation motor 62 is fixed to the vicinity of the fixed cylinder 25 on the base 10 and the shaft of the rotation motor 62 It is fixed to the stopper bar 64 and the rotational drive unit 94 and the forward rotation and reverse rotation 90 degrees by the motor 60. The rotational drive unit 94 drives the rotational motor 62 to rotate 90 degrees forward and 90 degrees by a control of the control unit 90 according to an operation of an operation button of the input unit 92 by an operator.

The first distance measuring device 70 measures the distance from the initial state to the reflecting plate 70 installed on the side of the jig holder 36. For example, a laser measuring device may be used.

The second distance measuring device 80 is for measuring the distance to the stopper bar 64 in a state in which the stopper bar 64 is rotated clockwise to be parallel to the upper surface of the base 10. For example, a laser meter can be used.

Next, the operation of the metal bar processing apparatus according to the second embodiment of the present invention configured as described above will be described.

First, when the operator operates the operation button of the input unit 42 in the initial state as shown in FIG. 12, the rotating motor 62 is rotated 90 degrees clockwise as the control unit 90 controls the driving of the rotating drive unit 94. As shown in FIG. 13, the stopper bar 64 descends in a state parallel to the upper surface of the base 10. Subsequently, the end of the machining portion of the metal rod 50 is brought into close contact with the stopper bar 64 through the groove 21a of the fixing portion 21 by the worker to process the metal rod 50 to be processed, and then the operation button of the input portion 42 is pressed. In operation, the first distance measuring device 70 measures the distance to the reflector 70 and the second distance measuring device 80 measures the distance to the stopper bar 64 under the control of the controller 90. From this, the controller 90 measures the length from the reflecting plate 39 to the tip of the molding jig 38 and the thickness of the stopper bar 64 in advance, so that the metal rod 50 at the tip of the molding jig 38 is measured. We can calculate the initial interval to the tip of

Subsequently, when the operator operates the operation button of the input unit 42, the control unit 90 drives the fixed drive unit 46 to control the driving of the fixed shaft 22 and the movable shaft 25 as the cylinder shaft 24 moves forward. As it moves forward toward the fixing part 21, as shown in FIG. 14, it comes into contact with the fixing part 21 to fix the metal rod 50, and the control part 90 drives the rotation driving part 94 to control the rotation motor. 62 is rotated 90 degrees in the counterclockwise direction to rise in a state perpendicular to the upper surface of the base 10.

Then, when the operator operates the operation button of the input unit 42, the control unit 90 controls the drive of the pressure drive unit 48 while driving control of the first distance measuring device 70, the pressure cylinder 31 is the cylinder shaft 32 The molding jig 38 advances toward the metal rod 50 as it is driven forward, and is pressed into the forming groove 37 from the end of the metal rod 50 as shown in FIG. 15. At this time, the controller 90 calculates the length of the metal rod 50 is pressed into the forming groove 37. That is, the control unit 90 subtracts the initial measurement value from the current measurement value of the first distance measuring device 70 by the value exceeding the initial interval from the tip of the molding jig 38 to the tip of the metal bar 50. The length 50 is press-fitted into the shaping groove 37.

When the metal rod 50 calculated as described above reaches the machining length of the desired metal rod 50 when the length pushed into the forming groove 37 reaches the processing length of the pressure driving unit 98, the control unit 90 drives the pressure cylinder 31 to control the pressure. As the c) drives the cylinder shaft 32 backward, as shown in Fig. 16, the molding jig 38 retreats to the initial initial position.

The control unit 40 drives the fixed drive unit 46 so that the fixed cylinder 22 drives the cylinder shaft 24 backward so that the movable unit 25 retreats to the initial position, thereby releasing the fixing of the metal rod 50. .

As described above, according to the second embodiment of the present invention, the end of the metal rod 50 can be processed to a desired diameter without the loss of raw materials. In addition, in the second embodiment, by employing the first and second length measuring instruments 70 and 80, there is an advantage that the processing length of the metal rod 50 can be selectively adjusted as compared with the first embodiment.
