Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an automatic grooving machine that cuts a cutting material with a plurality of cutters.

[0002]

[Prior art]

 There are various dimensions for the width of the groove used in general construction and the distance between the grooves depending on the application. Since the conventional automatic grooving machine has only one cutter axis, it was necessary to prepare a cutter suitable for the required groove width and replace it with a cutter corresponding to the groove width each time machining is performed. Recently, flexible cutters that can change the groove width are commercially available, but their use was limited because the cutting surface was not good and the bottom surface of the groove was R-shaped. Further, the gap between the grooves is changed by replacing the spacer inserted between the cutters with a spacer corresponding to the gap between the grooves. Further, when machining two-row or three-row grooves at one time, the shaft that supports the cutter becomes longer, but the shaft diameter is thicker than that of portable groove cutting so that there is no problem in strength. The cutter was also bigger than this. In addition, by using two-row and three-row grooves, a motor with a large output was used so that cutting could be performed even under heavy cutting loads.

[0003]

[Problems to be solved by the device]

 The conventional automatic grooving machine has the following problems. (1) The workability was poor because the cutter had to be replaced with a cutter according to the required groove width each time machining was performed. (2) Even when changing the distance between the grooves, it was necessary to replace the spacer inserted between the cutters, which required time before the work. (3) Even when using the universal cutter, when changing the groove width by a small amount, it was necessary to remove the universal cutter from the main body and adjust it in the same way as above, and the workability was poor. (4) Workers had to prepare several types of cutters, which were more expensive than portable ones, depending on the groove width, and had to spend a large amount of money to purchase the cutters. (5) Since the cutter diameter is large and a high-power motor is used, the product is heavy and large, making it difficult to move. It was also an expensive product. The object of the present invention is to eliminate the above-mentioned drawbacks of the prior art, to easily cut a desired groove width, two-row groove processing, deep groove processing, etc. without exchanging the cutter, and to provide a compact, lightweight and inexpensive automatic machine. The purpose is to provide a grooving machine.

[0004]

[Means for Solving the Problems]

 The above-mentioned object is to provide an automatic grooving machine provided with a material feeding device for feeding a cutting material to a position facing the table by projecting a cutter that is rotatably supported on the table surface, on the table surface. By providing a plurality of cutters protruding from each, and the plurality of cutters are respectively arranged in series with respect to the material feeding direction of the cutting material, and supported movably in a direction orthogonal to the material feeding direction. To be achieved.

[0005]

[Action]

 The automatic grooving machine configured as described above functions as follows. (1) The method of changing the groove width is to machine one groove with a plurality of cutters that are narrower than the groove width of the cutting material, and change the groove position by moving the cutter positions relatively. There is no need to replace the data. (2) When machining two-row or three-row grooves, each groove is processed by each cutter, and the distance between the grooves can be changed without changing the spacer by moving the cutter position relatively. (3) Grooves are processed by a combination, so the cutting load per sheet is reduced, and the cutter and motor output can be reduced.

FIG. 6 is an explanatory view during double-row groove processing, and FIG. 6 is an explanatory view during deep groove processing. In the figure, a table 2 is provided on a base 1, and a head 5 having a material feeding roller 4 serving as a material feeding device for feeding the cutting material 3 is provided at a position facing the upper surface of the table 2. Is fitted to the upper end of the column 6 inserted in the rear of the. The head 5 is provided with a raising / lowering handle 7, and by rotating the raising / lowering handle 7, the head 5 is raised / lowered via a feed screw 8. An opening is formed in the center of the table 2, and slide tables 11 and 12 are provided in the opening in series in the material feeding direction of the cutting material 3 (direction of arrow B in FIG. 1). A cutter 9 is provided on the slide table 11 and a cutter 10 is provided on the slide table 12, and the cutters 9 and 10 are rotationally driven by a motor (not shown). Inside the table 2, slide pipes 13 and 14 extending in a direction orthogonal to the feeding direction of the cutting material 3 (direction of arrow C in FIG. 2) are provided. The slide table 11 is a slide pipe 13 and the slide table 12 is a slide. The slide tables 11 and 12 are movable in the direction of arrow C by being supported by the pipes 14, respectively. Further, handles 15 and 16 are provided on the front side of the table 2, and the screw portion of the handle 15 is screwed into the lower portion of the slide table 11 and the screw portion of the handle 16 is screwed into the lower portion of the slide table 12, respectively. By rotating 16 respectively, the slide tables 11 and 12 move in the arrow C direction. A cutter housing 17 that rotatably supports the cutter 9 is rotatably supported on one side of the slide pipe 13 in the slide table 11. A worm 19 is engaged with an arc rack 18 provided in the cutter housing 17, and a knob 20 is provided at one end of the worm 19. When the knob 20 is rotated, the cutter housing 17 is rotated in the vertical direction via the circular arc rack 18, and the cutter housing 17 is rotated so that the protrusion amount of the cutter 9 protruding from the upper surface of the table 2 can be adjusted. it can. The height of the cutter 10 protruding from the upper surface of the table 2 can be adjusted by the same structure as the cutter 9 described above. Further, a guide 21 for guiding the feeding of the cutting material 3 is provided on the table 2. In the above configuration, when performing complex groove machining as shown in FIG. 4, the cutters 9 and 10 having a narrower width than the groove width of the cutting material 3 to be machined are attached to the knob 20 to rotate the cutter 9 against the upper surface of the table 2. Adjust the protruding position of 10 according to the desired groove depth, then move the cutter 9 to the position where the left side of the groove is cut with the handle 15, and the position where the right side of the groove is cut with the handle 16. 10 is moved so that the cutters 9 and 10 are partially overlapped with each other when viewed from FIG.

As shown in Fig. 5, when machining the first row with the cutter 9 and the second row with the cutter 10, the distance between the grooves can be changed easily by moving the positions of the cutters 9 and 10 with the handles 15 and 16. To be As shown in FIG. 6, when machining a deep groove, the positions of the cutters 9 and 10 are the same when viewed from FIG. 6, the knob 18 on the cutter 10 side is operated, and the cutter 10 is moved from the table 2 side rather than the cutter 9. Make it protrude significantly. At the time of grooving, first, the cutter 9 processes a groove having a depth of about half, and the cutter 10 processes the remaining depth. In this way, grooving can be performed with less cutting load per sheet.
