Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a section machine, and more particularly, to a so-called multi-type section machine capable of performing not only punching but also drilling and tapping with the same machine.

[0002]

2. Description of the Related Art For example, Japanese Unexamined Patent Publication No. 3-42133 discloses a shape steel processing machine for punching or cutting a shape steel (work) having various shapes such as an angle material and a channel material.
The one disclosed in Japanese Patent Application Publication No. H10-163, etc. is known.

Normally, in this type of section machine, a workpiece supplied to the table is cut, punched, or punched by a machine such as an angle cutter provided on the turret table. Then, the workpiece that has been processed by the section steel processing machine is carried to another processing machine, and thereafter, drilling and tapping are performed.

[0004]

As described above, hitherto, after performing cutting or punching with a shaped steel processing machine, the work is once removed from the apparatus, set on another processing machine, and then positioned again. Since drilling and tapping are performed, it is difficult to position the work during secondary processing such as the drilling. As a result, the processing position is easily shifted, and the quality of the product is deteriorated. In addition, it takes time and effort to remove the work from the section steel machine at the time of secondary processing, which is troublesome.

[0005]

In order to solve the above-mentioned problems caused by punching, drilling, tapping, and the like being performed by separate processing machines, the present invention provides a method for forming the same section steel processing machine. Each processing machine is set, the processing machine indexed to the processing position is detected, and the desired processing is performed on the workpiece by the processing machine. By repeating this, a plurality of types of processing are performed on the section steel by the same section steel processing machine.

[0006] By doing so, it is possible to continuously perform drilling, tapping, and the like from punching without removing the work, and the displacement of the processing position is suppressed.

[0007]

On the other hand, when the angle cutter is selected on the line L2 and the foot switch SF is depressed, the relay CR
2 is turned on, the relay CR2a of the line L4 is turned on,
The relay CR1b is turned on, and the relay CR of the line L3 is turned on.
2a turns on and relay CR1a turns off. as a result,
The ram drive solenoid YV is energized to drive the ram down, while the drill drive motor M is stopped.

As described above, it is detected whether the processing unit indexed to the processing position is a mold unit or a tool unit, and the corresponding processing unit drive unit is selectively operated in accordance with the detection result. Since the workpiece W is machined by the machining unit assigned to the machining position by transmitting the drive command, a plurality of types of machining can be performed by one machine, and the machining time can be reduced and the machining position can be reduced. It is possible to manufacture high-quality products without deviation.
