Description

Technical Field The present invention relates to a board processing apparatus and a board processing method,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate material processing apparatus and a plate material processing method, and more particularly, to a plate material processing apparatus and a plate material processing method capable of accurately processing a plate material capable of causing deflection.

It is very troublesome to perform processing such as drilling a hole in a plate having a large area and a relatively thin thickness (hereinafter referred to as a "plate") and tapping. A sheet having an area of more than a certain length is deflected if only both ends are supported. Particularly, when a force is applied by a tool, such as drilling a hole using a tool, deflection largely occurs around the machined portion.

Therefore, conventionally, in order to process a plate having a large area, a worker has been provided with a supporting device for supporting the periphery of the processing part. When the work is performed in this manner, there is a problem that it takes much time to move and install the plate material or the support device when the work needs to be performed in a plurality of places in one plate material.

If the area of the plate is not wide, it may be processed while moving the plate in the processing apparatus. When the area of the plate is wide and there are many places to be machined, it is convenient to fix the plate and to work while moving the tool. However, if the area of the plate is large, the plate material is not sagged if it is supported at a plurality of places. However, if there are many structures for supporting the plate material, flexibility of the processing device becomes low. If the structure for supporting is minimized, there is a problem that sagging occurs and the accuracy of machining is lowered.

Hereinafter, the processing of the plate material using the plate material processing apparatus and the plate material processing method according to the present invention having the above-described structure will be described in detail.

In the present invention, both end portions of the plate material 1 are fixed using the first and second end seating units 20 and 20 '. The distance between the first end seating unit 20 and the second end seating unit 20 'varies depending on the length of the plate 1. [ When the length of the plate material 1 to be processed is determined, the second end seating unit 20 'is moved so that the length of the first and second end seating units 20, 20' The distance between them is slightly longer. To this end, the movable stage 62 is moved to a proper position along the seating unit rail 60 in the second end seating unit 20 '.

Next, the plate 1 is seated on the rollers 24 of the first and second end seating units 20, 20 '. Both ends of the plate material 1 are inserted while rotating the roller 24. At this time, one end of the plate 1 is positioned at the origin O shown in FIG. The second end seating unit 20 'is moved toward the first end seating unit 20 in a state where both ends of the plate 1 are seated in the first and second end seating units 20 and 20' . Both ends of the plate 1 are moved by the movement of the second end seating unit 20 'to the stop faces of the stop bars 26 of the first end seating unit 20 and the second end seating unit 20' (26 '). Both ends of the plate 1 may be bent at a right angle as shown in FIG. 6 or the like so that the bent surface of the stop bar 26 is closely contacted. Of course, a separate cover made of an injection material may be placed on both end portions of the plate material 1 so that the injection material is brought into close contact with the stop bar 26.

The pressing unit 30 is operated while the both end portions of the plate 1 are seated on the first and second end seating units 20 and 20 ' . The reason why the elastic block 32 is brought into close contact with the plate member 1 is that the drive rod 37 is pressed by the pushing drive source 35 in a state where the pressing frame 31 is relatively positioned on the plate member 1 To the inside of the driving source (35). When the driving rod 37 enters the inside of the pushing drive source 35, the pushing frame 31 moves downward and the elastic block 32 is brought into close contact with the upper surface of the plate 1.

The first end seating unit 20 and the pushing unit 30 and the second end seating unit 20 'and the pushing unit 30 push the plate member 1 as described above, 1). Therefore, both ends of the plate material 1 can be firmly fixed.

Next, the tool unit 18 and the movable support unit 50 move while performing the machining. In this embodiment, the first tool 19 punctures the plate 1 and the second tool 19 'forms a tab in the hole. The tool unit 18 moves along the longitudinal rails 16 along the longitudinal rails 12 and 12 'so that the tool unit 18 moves along the longitudinal rails 16, The plate material 1 can be processed. The movable support unit 50 moves in one direction along the support rail 59 to support the plate 1 at a position where the tools 19 and 19 'are processed.

6 is a state in which the machining using the first tool 19 is ready. In this state, both end portions of the plate 1 are supported by the first and second end seating units 20 and 20 ', and the intermediate portion is supported by the two pairs of the fixed support units 40. Therefore, the plate material 1 is uniformly supported as a whole, and sagging does not occur.

When the first tool 19 is operated in the area between the first end seating unit 20 and the first fixed support unit 40, the two pairs of fixed support units 40, as shown in FIG. 6, Are all in an elevated state. The moving support unit 50 supports the lower surface of the plate 1 corresponding to the lower portion of the tool 19. [ Therefore, when the tool 19 passes through the plate material 1, it enters into the gap between the support blocks 56.

Next, when processing the area adjacent to the fixed support unit 40 on the left side in the drawing or the area between the two pairs of fixed support units 40, the left fixed support unit 40, . This is to prevent sagging of the plate 1 while avoiding interference between the fixed support unit 40 and the movable support unit 50.

When the tool 19 is machined at a position adjacent to the fixed support unit 40 on the right side in the figure or in a region between the second end seating unit 20 'and the right fixed support unit 40, The fixed support unit 40 on the right side is lowered and the movable support unit 50 supports the plate 1 at a position corresponding to the tool 19. [

When the plate member 1 is machined in this manner, the movable support unit 50 moves while the tool unit 18 moves and the fixed support unit 40 selectively supports the plate member 1 So that sagging of the plate material 1 as a whole does not occur. Of course, even if the movable supporting unit 50 directly supports the part to be processed by the tools 19, 19 ', the plate 1 is prevented from sagging, but it is required to be free from deflection in all areas of the entire plate 1 The tool 19, 19 'can perform the machining at the correct position.

For reference, in this embodiment, after the first tool 19 performs the boring operation on the entire plate material 1, the tool unit 18 moves to the initial position of FIG. 6, And the second tool 19 'performs tapping.

When the machining is completed, the tool unit 18 and the moving support unit 50 are moved to the initial position, and the state in which the pressing unit 30 presses both ends of the plate 1 is released, The sheet material 1 is unloaded from the sheet material processing apparatus of the present invention.
