Description

[Technical Field]

[0001] The present invention relates to an angular cutting device that cuts materials such as urethane foam and rubber sponge obliquely in the thickness direction. [Background technology]

[0002] Angular cutting, which involves cutting materials at an angle in the thickness direction, is one of the processing methods for urethane foam, rubber sponge, etc. For angular cutting, processing equipment such as a tapered slicer (see Non-Patent Document 1) or a tapered slicer (see Non-Patent Document 2), which are specialized for diagonal cutting, is used.

[0004] The above-mentioned conventional processing equipment is large enough to process large materials of about 1000 mm x 2000 mm, but it has low processing accuracy and is not suitable for processing small materials. Therefore, an object of the present invention is to provide an angular processing device that can perform angular processing with high precision even on small materials with widths and thicknesses of only a few centimeters. [Means for solving the problem]

[0005] The angular machining device of the present invention comprises a mounting table on which the workpiece is placed, a circular rotary blade that cuts the workpiece, the rotation axis of the rotary blade being supported at an angle to the thickness direction of the workpiece and supported so as to be slidable parallel to the rotation plane of the cutting edge of the rotary blade and parallel to the upper surface of the mounting table, and a groove formed on the mounting table in the sliding direction of the rotary blade, through which the cutting edge of the rotary blade passes, the surface that abuts against the cutting edge being a surface perpendicular to the rotation plane of the cutting edge of the rotary blade.

[0006] According to the angular machining device of the present invention, when a workpiece is placed on the mounting table and the rotary blade is slid, the cutting edge of the rotary blade passes through the groove and cuts the workpiece on the mounting table at an angle to its thickness (angular machining). At this time, the surface of the groove that abuts against the cutting edge of the rotary blade is a surface perpendicular to the rotation plane of the cutting edge of the rotary blade, so the angle of the cutting edge that enters the workpiece at an angle remains stable without swinging.

[0007] Furthermore, the angular machining device of the present invention is preferably a linear guide consisting of a guide rail and a slider that slides along the guide rail, and includes a linear guide that slidably supports the rotation axis of the rotary blade, and a handle for sliding the slider. This makes it possible to angularly machine a workpiece placed on a mounting table by grasping the handle and sliding the slider along the guide rail. [Effects of the Invention]

[0008] According to the angular machining device of the present invention, the angle of the cutting edge that enters the workpiece obliquely remains stable without any vibration, making it possible to angularly machine small materials with widths and thicknesses of only a few centimeters with high precision. [Brief explanation of the drawings]

[0009] [Figure 1]1 is a front view of an angular machining device according to an embodiment of the present invention. [Figure 2] 2 is a cross-sectional view taken along the line XX in FIG. 1. [Figure 3] FIG. 3 is an enlarged view of part A in FIG. 2. DETAILED DESCRIPTION OF THE INVENTION

[0010] FIG. 1 is a front view of an angular machining device according to an embodiment of the present invention, FIG. 2 is a cross-sectional view taken along line XX in FIG. 1, and FIG. 3 is an enlarged view of part A in FIG.

[0011] As shown in Figures 1 and 2, an angular machining device 1 according to an embodiment of the present invention has a mounting table 2 on which a workpiece M is placed, and a circular rotary blade 3 that cuts the workpiece M. The workpiece M is made of a material such as urethane foam or rubber sponge. The mounting table 2 is made of an acrylic plate about 5 mm thick. The mounting table 2 is easily replaceable because it may wear out due to contact with the rotary blade 3.

[0012] The mounting table 2 is fixed to a frame 4. The rotary blade 3 is mounted on a rotation shaft 6 of a motor 5. That is, the rotary blade 3 and the rotation shaft 6 of the motor 5 are common (coaxial). The motor 5 is supported by a linear guide 7. The linear guide 7 is composed of a guide rail 7A and a slider 7B. A handle 8 is provided on the slider 7B. The guide rail 7A is fixed to the frame 4 so as to extend horizontally. The slider 7B slides horizontally along the guide rail 7A.

[0013] The rotary blade 3 is supported with its rotation shaft 6 in a direction oblique to the thickness B direction of the workpiece M (in this embodiment, a direction at an angle θ=45°). Because the rotation shaft 6 is slidably supported by a linear guide 7, the rotary blade 3 slides parallel to the rotation plane 3B of its cutting edge 3A (see FIG. 3) and parallel to the upper surface 2A of the mounting table 2 (in the direction of arrow Z in FIG. 1).

[0014] As shown in Figure 3, a groove 9 through which the cutting edge 3A of the rotary blade 3 passes is formed on the mounting table 2. The groove 9 is formed to extend in the sliding direction of the rotary blade 3 (the direction of arrow Z in Figure 1). A surface 9A of the groove 9 that abuts against the cutting edge 3A is a plane that is perpendicular to the rotation plane 3B of the cutting edge 3A of the rotary blade 3. The cutting edge 3A of the rotary blade 3 comes into contact with and slides against the surface 9A of the groove 9, thereby cutting the workpiece M.

[0015] In this embodiment, the workpiece M is a sponge tape with an adhesive material on one side. The thickness B of the workpiece M is approximately 5 to 15 mm. The thickness of the rotary blade 3 is approximately 1 mm. The diameter of the rotary blade 3 is approximately 110 mm. The thickness and diameter of the rotary blade 3 can be changed depending on the material and thickness B of the workpiece M. Furthermore, the angle θ of the rotation shaft 6 can be changed. In this case, the surface 9A of the groove portion 9 is a surface that is perpendicular to the rotation plane 3B of the cutting edge 3A of the rotary blade 3, depending on the angle θ of the rotation shaft 6.

[0016] With the angular machining device 1 configured as described above, when the handle 8 is grasped and the slider 7B is slid while the workpiece M is placed on the mounting table 2, the cutting edge 3A of the rotary blade 3 passes through the groove 9 and cuts the workpiece M on the mounting table 2 at an angle relative to its thickness B (angular machining). At this time, the surface 9A of the groove 9 with which the cutting edge 3A of the rotary blade 3 comes into contact is a surface perpendicular to the rotation plane 3B of the cutting edge 3A, so the angle of the cutting edge 3A remains stable even with a thin rotary blade 3 with a thickness of about 1 mm. As a result, the cutting edge 3A does not wobble, making it possible to perform angular machining with high precision even on small materials with a width or thickness of only a few centimeters. [Industrial Applicability]

[0017] The angular processing device of the present invention is useful as a device for cutting materials such as urethane foam and rubber sponge diagonally in the thickness direction, and is particularly suitable as an angular processing device that can angularly process small materials with a width or thickness of only a few centimeters with high precision.
