Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate material processing apparatus capable of performing a pilot hole processing and a tapping on a material to be processed by a single apparatus.

[0002]

2. Description of the Related Art As is well known, in order to perform a predetermined tapping on a work material, after punching a prepared hole in the work material with a punching device in advance, the work material is transferred to the tapping device. Generally, tapping is performed based on the prepared hole.

As described above, when punching and tapping are performed by separate devices, the work is complicated because the work is transferred and the work efficiency is reduced. A device capable of punching and tapping has been proposed.

However, since many conventional apparatuses of this type are configured to fix a work piece on a base and perform a predetermined work, the work piece is moved each time punching or tapping is performed. This work is very complicated, and since the work is fixed to the base, the work space is at least four times the maximum work, which is It was also one of the factors that increased equipment costs. .

The present invention was devised in view of the above situation, and an object of the present invention is to prepare a hole for a workpiece and perform tapping with a single device.
Moreover, since the processing work space does not require more than twice as much as the maximum work, it is an object of the present invention to provide a small-sized and easy-to-use plate material processing apparatus capable of significantly reducing the equipment cost.

[0006]

In order to achieve the above object, according to the present invention, a plate material processing apparatus is provided with a work clamper for gripping a material to be processed and moving in the X-axis direction of a base.
A punching unit and a tapping unit that move in the Y-axis direction of the base above the workpiece moved by the work clamper, and move in the Y-axis direction of the base in synchronization with the punching unit and / or the tapping unit. And a stylus unit for positioning the tapping position on the workpiece, and the upper and lower dies of the punching unit and the drill and drill guide hole of the tapping unit are independently controlled for movement. It is characterized by being positioned.

A mounting portion 2 for mounting the processed material W is formed, and a guide rail 11 for transferring the processed material W is arranged along the carry-in portion and the mounting portion 2.

A stopper 1a is provided at each end of the base 1 and the carry-in section so that the workpiece W does not drop off from the carry-in section. On the upper surface of 2, a number of free ball bushes 2
a is provided in an aligned state, and the pass line of the workpiece W can be set.

The work clamper 10 is constructed so as to move along the guide rail 11 while gripping the workpiece W, and the liner 12 is movably fitted to the guide rail 11.

That is, the screw rod 1 is provided at the axial center of the guide rail 11 over substantially the entire length of the guide rail 11.
3 is provided, the screw rod 13 is configured to rotate in the forward and reverse directions by a motor 14 provided on the base 1 side, and the runner 12 is screwed onto the screw rod 13. Has been done.

The punching unit 20 and the tapping unit 30 are held by a gate-shaped support frame 3 arranged so as to traverse the base 1 in the Y-axis direction.
Along the guide rails 4 and 5 arranged above and below the Y
It is arranged so as to be movable in the axial direction.

That is, the upper die 21 of the punching unit 20 and the drill 31 of the tapping unit 30 are the base 4 of the guide rail 4 arranged above the support frame 3.
The lower die 22 of the punching unit 20 and the drill guide hole 32 of the tapping unit 30 are movably fitted to the base plate 5a of the guide rail 5 disposed below the support frame 3. Is movably mounted, and accordingly, the upper die 21 and the lower die 22 of the punching unit 20 and the drill 31 and the drill guide hole 32 of the tapping unit 30 are configured to be independently controlled and positioned. ing. .

The shaft cores of the guide rails 4 and 5 are
The screw rods 4b and 5b are arranged over substantially the entire lengths of the guide rails 4 and 5, and one screw rod 4b is directly rotated by a motor 6 arranged on the support frame 3 via a power transmission member 6a. Is configured to.

The other screw rod 5b is configured to rotate in synchronization with the screw rod 4b via a power transmission member 6b arranged between the screw rod 5b and the screw rod 4b.

Then, the above-mentioned screw rods 4b, 5
A nut (not shown), which is continuously held on the back surface side of each of the bases 4a and 5a, is screwed into b.

As described above, the stylus unit 40 includes the punching unit 20 and the tapping unit 30.
Centering the upper mold 21 and drill 31 on the base 1

Is tilted, the motor 6 or 14 is controlled to rotate forward or backward until the needle 41 becomes vertical. In this case, the detection signal from the sensor unit 43 is automatically input to the automatic control device C, and the automatic control device C determines the forward or reverse rotation amount of the motor 6 or 14 based on the signal from the sensor unit 43. (Angle) is calculated,
The command signal is fed back to the motor 6 or 14.

In this type of apparatus, the centering work is important for maintaining the product quality with high accuracy. To prevent this, the thermal expansion of the screw rods 13, 4b and 5b is performed. It is necessary to eliminate the effect of heat shrinkage.

Therefore, in this embodiment, the automatic position correction control device 50 is provided in order to cope with the temperature change of the screw rods 13, 4b and 5b.

As shown in FIG. 2, for example, the automatic position correction control device 50 will be described with reference to, for example, a screw rod 4b driven by a motor 6, and a bearing 51 fixedly arranged on the support frame 3. The screw rod 4b is supported by a bearing 52 movably arranged on the support frame 3, and a displacement sensor 53 is arranged adjacent to the bearing 52 so that the screw rod 4b expands or contracts depending on a temperature change. The expansion amount or the contraction amount at that time is detected by the displacement sensor 53, and the displacement amount is arithmetically processed by the automatic control device C to make the forward / reverse rotation amount (angle) of the motor 6 correspond to the displacement amount. The drive is controlled so that it is changed. In addition, the code | symbol C1 in the figure has shown the manual controller.

Therefore, according to the plate material processing apparatus of this embodiment, the work clamper 10 is moved in the X-axis direction of the base 1, and the punching unit 20 and the tapping unit 30 are moved in the Y-axis direction of the base 1. In addition, the punching unit 20 and the tapping unit 30 can be centered with high accuracy by the stylus unit 40, and the centering error due to heat can be automatically corrected by the automatic position correction control device 50. Since it is possible to automatically perform pre-drilling and tapping of the workpiece W with a single device with high accuracy, and it is not necessary to position the workpiece W while rotating it on the base. The space can be significantly reduced compared to conventional equipment, and the equipment cost can be reduced.

[0025]

As described above, according to the present invention, the work clamper is moved in the X-axis direction of the base, and the punching unit / tapping unit is moved in the Y-axis direction of the base. Since the upper die and lower die of the punching unit and the drill and the drill guide hole of the tapping unit are independently controlled, the punching unit and the tapping unit are automatically centered by the stylus unit. It is possible to perform high-precision and automatic pre-drilling of workpieces and tapping with a single device, and the installation space can be greatly reduced compared to conventional equipment, resulting in a significant equipment cost. There are many effects such as reduction.
