Description

  The present invention relates to a roll cutter device for continuously removing a cutting material by inserting a plate material through a pair of rolls that rotate in conjunction with each other.

  For example, as a technique for removing a component from a metal plate, die cutting using upper and lower punches is generally known (for example, Patent Document 1). In die cutting, the processing pressure is determined by the peripheral length of the part and the plate thickness. Therefore, when processing a component having a complicated shape, the peripheral length becomes long and a large processing pressure is required.

  For this reason, in order to mass-produce parts by die-cutting, it is indispensable to accumulate know-how such as performing two-stage punching according to the shape and thickness of the part. Moreover, in order to maintain the accuracy of the punching process, it is necessary to accurately manage and maintain the die including the cutting edge, and the current situation is that the cost increases for mass production of parts continuously. .

The cutting blade at a portion extending along the central axis of the die cut roll is in line contact with the plate material, and the cutting blade at a portion intersecting the central axis of the die cut roll is in point contact with the plate material. Since the cutting edge angle of the cutting blade at the part extending along the central axis of the die cut roll is set small, for example, round, triangular, square hole surroundings, and rectangular products without increasing the processing pressure Can be cut evenly.

  The roll cutter device will be described with reference to FIGS.

  As shown in FIGS. 1 and 2, the roll cutter device 1 has a plate thickness of 0 between a die-cut roll 3 having a circumferential cutting blade 2 (circumferential cutting blade) on the outer peripheral surface and the die-cut roll 3. An anvil roll 4 is provided as a receiving roll through which a plate material (for example, metal) of 0.1 mm to 2 mm (for example, about 0.3 mm) is inserted. By the interlocking rotation of the die cut roll 3 and the anvil roll 4, the plate material is cut by the cutting blade 2, and the material to be drawn (product) is continuously removed.

  A bearing 3 a is provided at the shaft end of the die cut roll 3, and a bearing 4 a is provided at the shaft end of the anvil roll 4. The die cut roll 3 and the anvil roll 4 are rotatably supported by the frame 5 via bearings 3a and 4a. The vertical position is adjustable. The die cut roll 3 is moved up and down by the elevating means 6, the distance between the axes of the die cut roll 3 and the anvil roll 4 is adjusted, and the thickness of the plate material and the processing pressure, which are plate thickness information, are adjusted. Then, the lifting means 6 generates a pressing force during cutting so as to receive a reaction force, and the plate material is cut by the cutting blade 2 with an appropriate pressure.

  As shown in FIG. 2, a power transmission mechanism 7 is provided outside the bearing 4 a of the anvil roll 4, and a rotational drive means 8 is connected to the power transmission mechanism 7. Information on the thickness of the plate material, information on the shape of the product, etc. is input to the control means 9, and the control means 9 sends a drive command to the rotation drive means 8 based on the information on the thickness of the plate material, information on the shape of the product, etc. Is output, and the rotational speeds of the die-cut roll 3 and the anvil roll 4 are adjusted. Further, a drive command is output from the control means 9 to the lifting / lowering means 6.

  An example of the cutting blade 2 and a product will be specifically described based on FIGS. 3 to 6.

  As shown in FIGS. 5 and 6, the product 11 to be cut by the roll cutter device 1 has a shape in which a round hole 13, a triangular hole 14, and a square hole 15 are extracted from a rectangular plate 10. Therefore, as shown in FIGS. 3 and 4, a rectangular cutting blade 16 for extracting the rectangular plate 10, a round cutting blade 17 for extracting the round hole 13, and a triangular hole 14 are provided on the peripheral surface of the die cut roll 3. A triangular cutting edge 18 for extracting and a square cutting edge 19 for extracting the square hole 15 are formed. The rectangular cutting edge 16, the round cutting edge 17, the triangular cutting edge 18, and the square cutting edge 19 are formed at equal intervals at three locations on the peripheral surface of the die cut roll 3.

  When the die cut roll 3 is moved up and down by the elevating means 6, the distance between the axes of the die cut roll 3 and the anvil roll 4 is adjusted and the cutting pressure is set. In this case, the bearer portion at the end of the die cut roll 3 is in contact with the peripheral surface of the anvil roll 4. The anvil roll 4 is driven and rotated through the power transmission mechanism 7 by driving the rotation driving means 8, and the die cut roll 3 is rotated to insert the plate material.

  As shown in FIGS. 5 and 6, the rectangular plate 10 is pulled out by the rectangular cutting blade 16 when the plate material 12 is inserted between the die cut roll 3 and the anvil roll 4. In the rectangular plate 10, the round hole 13 is extracted by the circular cutting blade 17, the triangular hole 14 is extracted by the triangular cutting blade 18, and the square hole 15 is extracted by the square cutting blade 19.

  The cutting blade at a portion extending along the central axis of the die cut roll 3 is in line contact with the plate material 12, and the cutting blade at a portion intersecting the central axis of the die cut roll 3 is in point contact with the plate material 12. Thereby, the pressure which acts on the cutting blade 2 at the time of a cutting | disconnection becomes higher than the pressure of the cutting blade of the site | part which cross | intersects the central axis of the die-cut roll 3, and the pressure of the cutting blade of the site | part extended along the central axis of the die-cut roll 3 becomes high. .

  For this reason, the cutting blade 2 is set so that the cutting edge angle of the cutting edge at the portion extending along the central axis of the die cut roll 3 is smaller than the cutting edge angle of the cutting blade at the portion intersecting the central axis of the die cutting roll 3. Yes. Therefore, by cutting the blade edge angle at the portion where the pressure acting on the cutting blade 2 is high, uniform cutting can be performed around the cutting blade 2 without increasing the processing pressure.

  A specific example of the blade edge angle will be described with reference to FIGS. 3 and 4.

  A portion 16 a in the longitudinal direction of the rectangular cutting edge 16, a portion 18 a corresponding to the bottom side of the triangular cutting edge 18, and a portion 19 a extending in the lateral direction of the square cutting edge 19 are portions extending along the central axis of the die cut roll 3. , Line contact is made to the plate material.

  The side part 18b connected to the apex of the triangular cutting edge 18 and the round cutting edge 17 are parts inclined to the central axis of the die-cut roll (intersection parts) and are in point contact with the plate material 12. Further, a portion 16c in the short direction of the rectangular cutting blade 16 and a portion 19c extending in the longitudinal direction of the square cutting blade 19 are portions orthogonal to the central axis of the die cut roll (intersection portions), and are in point contact with the plate material 12. It becomes.

  As shown in FIG. 4A, a longitudinal portion 16a of the rectangular cutting edge 16 and a triangular cutting edge 18 that extend along the central axis of the die cut roll 3 and are in line contact with the plate material 12. The portion 18a and the portion 19a extending in the lateral direction of the square cutting blade 19 have a high pressure acting on the cutting blade 2 during cutting. For this reason, a cutting edge having a small second angle (angle α1, for example, about 50 degrees) is formed at the cutting edge with respect to the cutting edge 2 having an angle α (for example, about 40 degrees) after machining.

  As shown in FIG. 4 (b), the part 18b on the side of the triangular cutting edge 18 and the round cutting edge 17 are parts that are inclined to the central axis of the die-cut roll and are in point contact with the plate material 12. The pressure acting on the cutting blade 2 during cutting is slightly lower. For this reason, the cutting edge 2 having a relatively small angle (angle α2, for example, about 60 degrees) is formed on the cutting edge with respect to the cutting edge 2 having the angle α after machining.

  As shown in FIG. 4C, a part 16c in the short direction of the rectangular cutting edge 16 that is a part perpendicular to the central axis of the die-cut roll and is a point contact with the plate member 12, and a square cutting edge The part 19c extending in the vertical direction 19 has a significantly low pressure acting on the cutting blade 2 during cutting. For this reason, a cutting edge having a large second angle (angle α3, for example, about 70 degrees) is formed at the cutting edge with respect to the cutting blade 2 having the angle α after machining.

  As described above, the blade edge angle of the portion where the pressure acting on the cutting blade 2 is high at the time of cutting is set to be smaller (α2, α1) than the blade edge angle (α3) of the portion where the pressure acting on the cutting blade 2 is low at the time of cutting. Yes. For this reason, without increasing the processing pressure, the part (periphery) in which the direction of the rectangular cutting edge 16 is different, the periphery of the round cutting edge 17, the part in which the direction of the triangular cutting edge 18 is different (periphery), and the direction of the square cutting edge 19 Can be cut evenly over different parts (surroundings).

  Even when the cutting blade is fine and has a complicated shape, a small second angle can be formed on the cutting edge at an appropriate place.

  The roll cutter device 1 described above is a rectangular cutting blade, which is a circumferential cutting blade, by inserting a plate material 12 (metal plate material) having a plate thickness of 0.1 mm to 2 mm between a continuously rotating die cut roll 3 and an anvil roll 4. The plate material is cut by the cutting blade 16, the round cutting blade 17, the triangular cutting blade 18, and the square cutting blade 19, and the product 11 is continuously removed from the plate material. For this reason, the product similar to the product obtained by die cutting can be continuously obtained in large quantities.

  Then, between the continuously rotating die-cut roll 3 and the anvil roll 4, the plate material 12 is cut by a rectangular cutting blade 16, a round cutting blade 17, a triangular cutting blade 18, and a square cutting blade 19 that are circumferential cutting blades. Therefore, the length of the point contact can be increased, and the processing pressure can be stabilized regardless of the shape of the product 11.

  Further, the distance between the axes of the die-cut roll 3 and the anvil roll 4 is adjusted based on the thickness of the plate 12, the shape of the product 11, and the like, and the rectangular cutting blade 16, the round cutting blade 17, and the triangular cutting blade are accurately pressured. 18, the plate material 12 is cut by the square cutting edge 19. Further, based on the thickness of the plate 12, the shape of the product 11, etc., the rotational speed of the die cut roll 3 and the anvil roll 4 is adjusted by the rotation driving means 8, and the plate 12 is fed at an accurate feed speed to make a rectangular cut. The plate 12 is cut by the blade 16, the round cutting blade 17, the triangular cutting blade 18, and the square cutting blade 19.

  Moreover, since the cutting edge 2 of the site | part in which the contact with the board | plate material 12 becomes a line contact is set smaller than the cutting blade 2 of the site | part in which the contact with the board | plate material 12 becomes a point contact, processing pressure is made high. Without cutting, it is possible to perform uniform cutting around the cutting blade 2. Then, the product 11 is continuously removed from the plate material 12 by the rectangular cutting blade 16, the round cutting blade 17, the triangular cutting blade 18, and the square cutting blade 19 with respect to the plate material 12 having a thickness of 0.1 mm to 2 mm. Can do.

  In the embodiment described above, the longitudinal direction of the rectangular cutting edge 16 is arranged in the direction along the central axis of the die cut roll 3, and the short side direction is arranged in the direction orthogonal to the central axis of the die cut roll 3, FIG. As shown, the rectangular cutting edge 16 can be inclined with respect to the central axis of the die cutting roll 3, and the longitudinal direction and the short direction of the rectangular cutting edge 16 can be arranged in a direction intersecting the central axis of the die cutting roll 3. . Thereby, the cutting blade 2 can be arrange | positioned in the state in which there exist many parts of the direction which cross | intersects with respect to the central axis of the die-cut roll 3, and the pressure which acts on a cutting blade at the time of a cutting | disconnection can be suppressed.

  Further, the shape of the product 11 produced by the roll cutter device 1 of the present invention, the thickness of the plate material 12 and the material are examples, and the plate thickness is from 0.1 mm to 2 mm, preferably 0 mm. With respect to a plate material of 3 mm to 1 mm, a product in which many kinds of holes of various patterns are formed by a circumferential cutting blade can be continuously removed from the plate material.

  As described above, the die cutting roll 3 is formed with the rectangular cutting edge 16, the round cutting edge 17, the triangular cutting edge 18, and the square cutting edge 19. Grooves can be formed on the peripheral surface of the die cut roll 3 between the rectangular cutting edge 16, the round cutting edge 17, the triangular cutting edge 18, and the square cutting edge 19. By forming the grooves, when machining the cutting edges of the rectangular cutting edge 16, the round cutting edge 17, the triangular cutting edge 18, and the square cutting edge 19, a part of the processing tool can be released by the groove.

  That is, the cutting edge of the rectangular cutting edge 16, the round cutting edge 17, the triangular cutting edge 18, and the square cutting edge 19 can be processed in a state in which a part of the processing tool is arranged in the groove. It is possible to process the cutting edge at an arbitrary angle without a part of the interference with the peripheral surface of the die cut roll 3. In other words, even if the intervals between the rectangular cutting edge 16, the round cutting edge 17, the triangular cutting edge 18, and the square cutting edge 19 are narrowed, it is possible to process a cutting edge having a desired angle.

  Therefore, the product 11 in which the round holes 13, the triangular holes 14, and the square holes 15 are arranged can be obtained in a state where the interval is narrow. In other words, a cutting blade capable of extracting a number of extremely small holes can be formed on the die cut roll 3.

  INDUSTRIAL APPLICABILITY The present invention can be used in the industrial field of a roll cutter device that continuously removes a cutting material by inserting a plate material through a pair of rolls that rotate in conjunction with each other.
