  • Publication number: 20210299793
    Abstract: A laser processing apparatus includes: a work support portion which supports the work and forms a closed space between the work and the work support portion; pads which are movable upward and downward inside the closed space and include upper surfaces respectively coming into contact with regions obtained by dividing a processing object region having the through-holes formed in the work to surround the region of the work over one circle when the pads move upward; a drive unit which drives the pads to move forward and backward between a state in which the pad is in contact with the work and a state in which the pad is separated from the work; a gas supply unit which supplies a gas into the closed space; and clamps which contact the work supported by the work support portion on inner circumferential surfaces and outer circumferential surfaces from above over one circle.

  • Publication number: 20210283748
    Abstract: A drilling method capable of preventing hole clogging easily and at low cost is provided. A drilling method of the disclosure includes: a hole forming step in which a surface of a workpiece is drilled to form at least one penetration hole from the surface to a back surface of the workpiece; a liquid intrusion step in which the workpiece is immersed in a tank containing a liquid, and the inside of the tank is decompressed to a predetermined pressure to allow the liquid to intrude into the penetration holes; a liquid solidification step in which the liquid that has intruded into the penetration holes is solidified after the workpiece is taken out of the tank; and a burr removing step in which the surface of the workpiece is blasted to remove burrs formed around openings of the penetration holes.

  • Publication number: 20210268603
    Abstract: A laser processing apparatus 3 includes: a laser head H; a head driving mechanism that moves the laser head H above a workpiece W; and a dust collecting box 60 that moves below the workpiece W and follows the laser head H. A non-contact support unit 7 is provided at an opening 61 of the dust collecting box 60, and the non-contact support unit 7 suctions a lower surface of the workpiece W toward a suction surface 71 and supports the workpiece W without bringing the lower surface of the workpiece W and the suction surface 71 into contact with each other. An outer support roller 81 and an inner support roller 82 that are each rotatable about an axis parallel to a width direction orthogonal or substantially orthogonal to a conveying direction Fy are provided at the opening 61.

  • Patent number: 9192974
    Abstract: A work-punching device and work-punching method capable of appropriately changing a counter load is provided. Also, a method for manufacturing an element for continuously variable transmission with simple process is provided. A counter load may be controlled by increasing and decreasing a pressure of a fluid, when punching an element 10 from a metal band plate 20 while applying a counter load by a counter punch 113.

  • Publication number: 20130227999
    Abstract: Provided is a workpiece punch-molding method and a workpiece punch-molding device capable of maintaining the thickness of a workpiece at a constant precision. Prior to the punch of a workpiece by a mold punch and a counter punch, the data denoting a relationship between a punch speed of the mold punch and a delay time of the depressurization of the counter punch is obtained. The counter punch is subjected to the depressurization at an early timing based on the obtained data.
