As a result, the vertical position of the movable block 18b can be adjusted according to the specification of the metal material to be tapped. As a result, the height of the tab drill 14 is adjusted by adjusting the vertical position of the movable block 18b, It is possible to tap the metal material of the specification.

That is, the height of the entire movable block 18b including the tab drill 14 can be adjusted by operating the bolts 35 that pass through the slots 30 of the movable block 18b and are fastened to the fixed block 18a do.

The input shaft 13 extending to the upper side of the drive unit 13 is connected to the shaft of the drive motor 12 through a coupling 31 so that power can be transmitted. So that it can be transmitted to the reduction gear portion 16.

At this time, the reduction gear portion 16 is a means for outputting the power (rotation speed) received through the input shaft 13 through the output shaft 17 after appropriately decelerating the gear using the plurality of gear combinations, and a known reduction gear device or the like Can be applied.

The output shaft 17 is elongated downwardly of the reduction gear portion 16 and is positioned so as to pass through the movable block 18b of the unit block 18. The output shaft 17 is connected to the spline gear 14 side, So that the power can be transmitted.

At this time, the output shaft 17 can be formed as a shaft having a rectangular cross-section. Accordingly, when the movable block 18b is vertically adjusted, the output shaft 17 is rotated with its transmission gear (not shown) And the tab drill 14 can be rotated by the transmission between the transmission gears when the output shaft 17 is rotated.

A tap drill 14 is provided as a means of machining a substantially metallic material.

This sensor device 19 can be of a type that detects direct contact with the tap drill 14, a type that detects a proximity to the tap drill 14, and the like.

Thus, when the lower end of the tab drill 14, which passes through the metal material and goes down further down after the tab is formed in the metal material during tapping, comes into contact with or approaches the sensor device 19, .

When the sensing signal of the sensor device 19 is provided to the controller 25, tapping is normally performed, and the entire operation of the device can be normally performed.

On the other hand, if the tap drill 14 can not be detected by the sensor device 19 due to the tap processing failure and the detection signal from the sensor device 19 is not input to the controller 25 side, So that the efficiency of the device operation can be improved, for example, the operator can reduce defects without checking the tapping state.

Therefore, the overall operating state of the multi-forming machine having the tap forming apparatus constructed as described above will be described below.

The multi-forming machine equipped with the tapping device is a step in which the feeding of the raw material by the feeding part is performed by the feeder 20 while the metallic material is being fed stepwise, the pressing of the metallic material by the press 10, And the foaming process of the metal material by the forming machine 10 are sequentially performed, and the entire process from the input of the raw material to the production of the finished product can be performed by the continuous automation process.

For example, the raw material, that is, the strip-shaped plate material is supplied from the supply unit, and is fed by the feeder 20 in a stepwise manner, and grooves or holes are formed in the press 10, After the tabs are processed in the holes of the material, the foaming machine 11 is then subjected to foaming and cutting several times to finally produce miniature precision finished metal products of various shapes.

Hereinafter, the tap forming process performed by the tapping device 26 will be described.

When the metal material, for example, a hole material, which has been subjected to the pressing process in the press 10 is placed in the tapped area along the rail 32, the tappetting device 26 starts operating from this time, Machining can be performed.

Of course, a separate sensor (not shown) or the like senses that the metal material is positioned at the bottom of the tap drilling machine 14, and the operation of the tapping machine 26 can thereby be started.

Therefore, the power by the operation of the drive motor 12 is transmitted to the metal material by the rotation of the tab drill 14 while continuing to the input shaft 15 → the reduction gear portion 16 → the output shaft 17 → the tab drill 14 So that tapping is performed on the surface.

At this time, cutting oil is smoothly supplied to the tapping part of the metal material from the cutting oil supply part (33) on one side of the tap drill (14).

When the tab drill 14, which has passed through the metal material after the tapping, touches the sensor device 19, it is determined that tapping is normally performed, and then continuous tapping is performed.

If the tap drill 14 does not touch the sensor device 19, it is determined that the tap drilling operation or the tap drill is broken and the entire operation of the facility can be automatically stopped.

Accordingly, it is possible to reduce the tapping defects without having to confirm the tapping state by the operator.

As described above, in the present invention, the tap forming device is provided in the multi-forming machine so that the tapping of the metal material is continuously performed in conjunction with the pressing process and the forming process, and in particular, By stopping the entire operation of the equipment automatically, it is possible to reduce the tapping defects and improve the operation efficiency of the entire equipment.
