Description

[Detailed Description of the Invention] This invention relates to a bar end processing device.

Conventionally, as a decorative opening frame material, a bar 1 has been manufactured by laminating three strip plates 2 to 4 in a groove shape and covering the outer surface with a decorative sheet 5 made of vinyl chloride sheet or the like, as shown in FIG. has been done. Since this bar 1 is a framework, tapered notches 6 and 7 are provided on the left or right half of the end in the width direction, as shown in FIGS. 2, 3, or 4. As shown in FIG. 5, a central notch 8 having a rectangular planar shape is provided at the center of the end. However, in the past, each of these notches 6 to 8 was manually provided, which was inefficient.

Therefore, the purpose of this invention is to provide an end processing device that can easily process both a tapered notch that is inclined with respect to the main surface of the bar and a notch that is perpendicular to the main surface of the bar at the end of the bar. It is to be.

An embodiment of this invention is shown in FIGS. 6 and 7. In the figure, reference numeral 9 denotes a bar placement table on which one bar 1 can be placed. The bar placement table 9 has an end reference guide 10 on one end of which the end surface of the bar 1 comes into contact.
It has a pair of side reference guides 11 and 12 near one end that face each other in the width direction.
Furthermore, a pair of side clamp cylinders 13 and 14 are provided near one end of the bar placement table 9 and are opposed in the width direction.
and a downwardly facing upper surface clamp cylinder 15 are provided. Reference numeral 16 denotes a rotating frame having a slide guide 17, which is arranged near one end of the bar placement table 9 at its extended position. A movable base 19 on which a rotary cutter 18 is installed is movably attached to the slide guide 17, and the movable base 19 is movably mounted on the slide guide 17.
9 is performed. rotating cutter 18
consists of a drive motor 21 and a rotary blade 22. The rotating frame 16 has support pins 26 that are slidably fitted into a pair of arcuate holes 25 provided in the side plates 24 of the base frame 23.
It is rotatable around the horizontal axis Q by the support of the support pin 26. The range in which the slide guide 17 can rotate is approximately 45 degrees as shown in Figure 7.
This is the range between the angle at which the slide guide 17 is tilted and the angle at which the slide guide 17 stands upright. A worm wheel 27 is fixed to the rotating frame 16 at the horizontal axis Q, and is rotationally driven by a motor (not shown) via a worm 28 that meshes with the worm wheel 27. The worm 28 is supported by the base frame 23 via a bearing 29.

Next, the operation of this bar end processing device will be explained. First, the case where the tapered notch 6 shown in FIG. 2 is provided will be explained. In this case, bar 1 is the sixth
Positioning in the width direction is performed by pressing the side reference guide 11 shown on the upper side of the figure with the side clamp cylinder 14 shown on the lower side of the figure. The end of the bar 1 is brought into contact with the end reference guide 10, and the upper clamp cylinder 15 presses the bar 1 against the upper surface of the bar placement table 9. On the other hand, the rotating frame 16 is set so that the slide guide 17 is inclined at 45 degrees as shown in FIG. After the clamping of the bar 1 and the setting of the rotary cutter 18 are completed in this manner, the rotary cutter 18 is lowered and raised once in a reciprocating manner along the slide guide 17 by the elevating drive cylinder 20. By moving the rotary cutter 18 in the oblique direction in this manner, the tapered notch 6 shown in FIG. 2 is formed.

When machining the tapered notch 7 in FIG. 4, the bar 1 is positioned by pressing it against the lower side reference guide 12 in FIG. 6 with the upper side clamp cylinder 13. Other operations are the same as those for machining the tapered notch 6 in FIG.

When providing the central notch 8 shown in FIG. 5, either one of the lower side reference guides 12 shown in FIG.
The bar 1 is brought into contact with the bar 1 through a liner (not shown) and clamped by the upper side clamp cylinder 13. In this way, the bar 1 is moved to the guide 1 on both sides.
Position it in the center between 1 and 12. The rotation frame 16 is set at an angle such that the slide guide 17 stands upright. In this way, by vertically raising and lowering the rotary cutter 18 along the slide guide 17, the fifth
As shown in the figure, there is a central notch 8 in the center of the end of the bar 1.
is formed. In this way, the tapered notches 6 and 7 on both sides and the central notch 8 can be processed with one device. Moreover, since it is only necessary to move the rotary cutter 18 up and down during machining, the machining can be carried out efficiently.

Note that in the above embodiment, the rotary cutter 18 was moved only in the direction along the slide guide 17, but for example, the moving base 19 installed on the slide guide 17 is provided with a widthwise slide guide along the width direction of the bar 1. (not shown), and the rotary cutter 18 may be movably installed on this width direction slide guide. As a result, each notch 6
Even if the width of the bar 1 is wider than the rotary blade 22 of the rotary cutter 18, the bar 1 can be processed while being initially clamped. Further, in the embodiment, the first
Although the case of processing the groove-shaped decorative frame material shown in the figure has been described, it can also be used for processing the end of a solid bar.

As described above, the bar end processing device of this invention is provided with a rotary frame having a slide guide so as to be rotatable between an upright position and a tilted position, and a rotary frame having a slide guide. Since the rotary cutter is provided so as to be movable along the bar, both a tapered notch and a vertical notch can be easily and efficiently formed at the end of the bar.
