[0039]
Now, using the cutting device configured as described above, the rounded surface 3 is cut at the apex corner portion 2 of the corner panel 1, and then the rounded surface 3 and the flat surfaces 4 and 5 are paneled. A method of cutting the design groove 8 extending in the width direction will be described in the order of steps.
[0040]
(1) As shown in FIG. 1, in an initial state in which the moving plate 15, the pedestal 23, etc. of the panel support mechanism and the panel rotation mechanism are moved to the right side of the base 11 so as not to be applied to the round and chamfering cutting mechanism 40, The corner panel 1 is placed on the gantry 23 with the apex corner portion 2 facing upward. That is, the corner panel 1 is mounted in a cross-sectional angled posture. Subsequently, when the start switch of the control device is operated, as shown in FIG. 9A, the air cylinder 28 of the gripping claw mechanism 26 is operated, and both edges of the outer surface of the corner panel 1 are paired with a pair of gripping claws 27. Is gripped by.
[0041]
(2) Subsequently, as shown in FIG. 2, FIG. 5, FIG. 6 and FIG. 9 (b), the panel moving motor 20 is operated, and the corner panel 1 is moved in the panel length direction together with the panel supporting mechanism and the panel rotating mechanism. Start moving in a certain left direction. The moving speed is preferably 20 to 250 mm / second, more preferably 80 to 200 mm / second. If it is earlier than the same range, the panel 1 tends to be chipped, and if it is late, the efficiency becomes worse. In addition, the rounding and chamfering cutting motor 50 operates, the rounding cutting blade 51 and the chamfering cutting blade 55 rotate, and the lifting and lowering motor 45 operates, so that the rounding cutting blade 51 and the chamfering cutting blade 55 have a predetermined height level. Descend to
[0042]
When the corner panel 1 moved to the left is applied to the rounded cutting edge 51 and the chamfering cutting edge 55, the rounded cutting edge 51 acts on the apex corner portion 2 to cut the rounded face 3, and at the same time The chamfering cutting blade 55 acts on the corner edge 6 to cut the chamfer 7. At this time, as shown in FIG. 6 and FIG. 9B, each gripping claw mechanism 26 acts on the radius cutting blade 51 and the chamfering cutting blade 55 immediately before and after the radius cutting blade 51 and the chamfering cutting blade 55. The pair of gripping claws 27 are opened so as not to disturb the gripping, and the gripping is resumed when the gripping blade 51 and the chamfering cutting blade 55 are slightly separated from each other. During this process, the cutting powder is sucked from the cutting powder suction duct 58, so that the work environment is not harmed.
[0043]
(3) When the corner panel 1 passes through the round cutting blade 51 and the chamfering cutting blade 55 and moves a little further to the left from the position shown in FIG. Then, the round and chamfering cutting motor 50 is stopped, the lifting motor 45 is operated in reverse, and the rounding cutting blade 51 and the chamfering cutting blade 55 are raised. Further, the panel rotation motor 25 is operated, and the corner panel 1 is rotated 45 degrees forward about the R center line 3a together with the gantry 23 by the action of the eccentric member 22 as shown in FIG. Left-handed in the figure), the first flat surface 4 stands still in a posture where it is horizontal upward.
[0044]
(4) Subsequently, the air cylinder 77 and the forward / backward movement motor (not shown) of the groove cutting mechanism 70 are operated to cut each groove together with the mounting plate 75 and the like as shown in FIGS. 10 (b) and 11 (a). The blade 82 moves forward and slides on the flat surface 4 of the stationary corner panel 1, and the linear portion 8 a of the design groove 8 is cut on the flat surface 4. The slide speed is preferably 10 to 120 mm / second, more preferably 30 to 100 mm / second. If it is earlier than the same range, the panel 1 tends to be chipped, and if it is late, the efficiency becomes worse. As shown in FIG. 11A, when the groove cutting blade 82 moves forward to the radius start point of the radius surface 3, it stops and localizes.
[0045]
Subsequently, the panel rotation motor 25 is operated, and the corner panel 1 is centered on the center line 3a together with the gantry 23 by the action of the eccentric member 22 as shown in FIGS. 11 (b) and 12 (a). It rotates 90 ° rearward (clockwise in the figure), and each groove cutting blade 82 in the above-mentioned orientation acts on the rounded surface 3 to cut the rounded portion 8 b of the design groove 8. The rotation speed is preferably 5 to 35 degrees / second, more preferably 10 to 30 degrees / second. If it is earlier than the same range, the panel 1 tends to be chipped, and if it is late, the efficiency becomes worse. The corner panel 1 ends this 90 ° rotation, and rests in a posture in which the second flat surface 5 is leveled upward. At this time, even if cutting powder remains in the linear portion 8a and the rounded portion 8b, the cutting powder falls and is removed.
[0046]
Subsequently, the air cylinder 77 and the forward / backward movement motor are operated, and as shown in FIG. 12B, each groove cutting blade 82 resumes moving forward and slides on the flat surface 5 of the stationary corner panel 1. The linear portion 8c of the design groove 8 is cut on the flat surface 5 by acting.
Thus, a plurality of design grooves 8 extending in the panel width direction are formed on the outer surface of the corner panel 1 at intervals of 200 mm.
During this process, the cutting powder is prevented from being scattered to the surroundings by the cutting powder scattering preventing piece 85 and is sucked from the cutting powder suction duct 86, so that the work environment is not harmed.
[0047]
(5) Subsequently, the panel moving motor 20 is operated, and the corner panel 1 is moved 100 mm to the left together with the panel support mechanism and the panel rotation mechanism while the flat surface 5 remains in the horizontal position upward. Quiesce.
[0048]
Then, the air cylinder 77 and the longitudinal motor are actuated, and as shown in FIGS. 13 (a) and 13 (b), each groove cutting blade 82 moves backward and slides on the flat surface 5 of the corner panel 1 in the stationary state. The line portion 8 c of the next design groove 8 is cut on the flat surface 5. As shown in FIG. 13B, the groove cutting blade 82 stops and localizes when it advances to the radius start point of the radius surface 3.
[0049]
Subsequently, the panel rotating motor 25 is operated, and the corner panel 1 is moved forward 90 around the center line 3a together with the pedestal 23 by the action of the eccentric member 22 as shown in FIGS. 14 (a) and 14 (b). Rotate (clockwise in the figure), and each groove cutting blade 82 in the above-mentioned orientation acts on the rounded surface 3, and the rounded portion 8b of the design groove 8 is cut. The corner panel 1 stops at the posture in which the 90 ° rotation is finished and the flat surface 4 is horizontal upward. At this time, even if cutting powder remains in the linear portion 8c and the rounded portion 8b, the cutting powder drops and is removed.
[0050]
Subsequently, the air cylinder 77 and the longitudinal motor are actuated, and as shown in FIG. 15A, each groove cutting blade 82 resumes retreating and slides on the flat surface 4 of the corner panel 1 in the stationary state. The line 8a of the design groove 8 is cut on the flat surface 4 by acting. FIG. 3 shows the state at this time.
[0051]
Thus, the next plurality of design grooves 8 extending in the panel width direction are formed on the outer surface of the corner panel 1 at intervals of 200 mm. In FIG. 15B, the design groove 8 appearing on the left side is formed in the step (4), and the design groove 8 appearing on the right side is formed in the step (5). When both design grooves 8 are viewed together, the design grooves 8 are formed at intervals of 100 mm.
[0052]
(6) Subsequently, the panel rotating motor 25 is operated, and once the corner panel 1 is rotated 90 ° backward about the R center line 3a together with the gantry 23, the cutting powder remaining on the linear portion 8a is dropped. After being removed, the corner panel 1 is rotated 45 ° forward and the rounded surface 3 is directed upward.
[0053]
Subsequently, the panel moving motor 20 is operated, the corner panel 1 is moved to the right together with the panel support mechanism and the panel rotating mechanism, the gripping claws 27 are opened, the gripping is released, and the initial state of (1) is reached. Since it returns, the corner panel 1 should just be removed from the mount frame 23.
[0054]
According to the cutting method of this embodiment performed by the above process, the following effects are obtained.
[0055]
(A) Since the work of cutting and forming the design groove 8 extending in the panel width direction is automated, not only skill is required, but it is not troublesome, and the finishing accuracy of the product is stable.
[0056]
(B) The cutting process of the rounded portion 8b of the design groove 8 on the rounded surface 3 only rotates the corner panel 1 about the rounded center line 3a, so the groove cutting blade 82 and the groove cutting motor 80 are rotated and moved. Therefore, the structure on the groove cutting mechanism side is not complicated. The structure on the panel rotating mechanism side is simple. In addition, an unnatural force is applied, and therefore, there is no part where wear becomes intense, and failure is not likely to occur. Furthermore, there is almost no movement of the center of gravity of the corner panel 1, and therefore the amount of work required for rotational driving can be reduced.
[0057]
(C) Since the cutting of the linear portions 8a and 8c of the design groove 8 on the flat surfaces 4 and 5 is merely sliding the groove cutting blade 82, the structure on the panel rotating mechanism side is not complicated. If a motion corresponding to the slide is applied to the panel rotation mechanism, the structure becomes extremely complicated. On the other hand, the structure on the blade slide mechanism side of the groove cutting blade 82 may be simple. That is, in this apparatus, the movement necessary for the cutting of the rounded portion 8b is imposed on the panel rotation mechanism, and the movement necessary for the cutting of the linear portions 8a and 8c is imparted to the blade slide mechanism, that is, is shared. The structure of each mechanism can be prevented from becoming complicated, and the structure can be simplified.
[0058]
(D) The work of cutting the rounded surface 3 and the work of cutting the chamfer 7 may be performed by moving the corner panel 1 in the same panel length direction with respect to the cutting blades 51 and 55. Therefore, these operations can be performed at the same time, and the efficiency can be increased by performing an operation for cutting the design groove 8 after that.
[0059]
(E) The round and chamfering cutting mechanism 40 and the groove cutting mechanism 70 are continuously arranged, and the corner panel 1 is placed on a single pedestal 23 and moved to the round and chamfering cutting mechanism 40. Since the corner panel 1 is positioned in the vicinity of the front surface of the groove cutting mechanism 70 after cutting the groove, groove cutting can be performed continuously and the efficiency is high. Further, the groove machining accuracy (particularly position accuracy) is high.
[0060]
(F) After the design groove 8 is formed in the step (4), the corner panel 1 is moved slightly in the panel length direction in the step (5) to form the next design groove, whereby the groove cutting blade 82 Design grooves can be formed at an interval smaller than the mutual interval. This method is effective when the interval between the groove cutting blades 82 cannot be reduced because the groove cutting motor 80 is large.
[0061]
In addition, this invention is not limited to the said embodiment, For example, it can also be suitably changed and embodied as follows, for example in the range which does not deviate from the meaning of invention.
[0062]
(1) The radius cutting blade is not limited to that of the above-described embodiment. For example, as shown in FIG. 16, two radius cutting blades 62 having a shape having an axially symmetrical concave arc are provided. May be. 63 is a motor for cutting.
[0063]
(2) When cutting the rounded surface 3, a design groove extending in the panel length direction is cut instead of or in addition to the chamfer cutting. In this case, a groove cutting blade for cutting the design groove is provided instead of or in addition to the chamfered cutting blade.
[0064]
(3) The design groove 8 is not limited to a two-stage structure, and may be one stage or three or more stages. The design groove 8 may extend in the panel width direction and may be inclined or curved in the panel length direction. What is necessary is just to comprise such a design groove | channel so that the corner panel 1 may be moved to a panel length direction at the time of groove cutting.
[0065]
