Abstract
A punching device is provided with a punching head, a vacuum apparatus, a suction flow passage, and a suction switching apparatus. The punching head includes a plurality of hollow rods that move vertically, and punching tools each having an axially extending through hole provided at each front end of the hollow rods. The vacuum apparatus serves to suck punched chips generated during the punching process of the punching head. The suction flow passage selectively communicates the through holes of the punching tools with the vacuum apparatus. The suction switching apparatus changes a path of the suction flow passage so that the suction flow passage communicates only with a hollow rod performing a punching process, among the plurality of hollow rods.
Claims15
A punching device, comprising:
- a punching head including punching tools, each of the punching tools having an axially extending through hole;
- a suction apparatus comprised of a vacuum is configured to suck a punched chip generated during a punching process by one of the punching tools;
- a suction switching apparatus configured to increase a suction in the punching tool performing the punching process, as compared to the punching tool(s) not performing the punching process, said suction switching apparatus comprises a flow passage switching mechanism configured to change a path of a suction flow passage such that the suction of the punching tool performing the punching process can be increased;
- and wherein the flow passage switching mechanism comprises:
- a connection member formed with connection openings disposed along a circular arc line;
- and
- a rotary member formed with a suction opening which selectively communicates with one of the connection openings in accordance with a rotation of the rotary member about a center of the circular arc line as a rotational center thereof.
A punching device, comprising:
- a punching head including a first hollow rod with a first punching tool and a second hollow rod with a second punching tool, the first and second hollow rods each having an axially extending through hole;
- a suction apparatus configured to create a suction flow path along a first path including the through hole of the first hollow rod or a second path including the through hole of the second hollow rod;
- a suction switching apparatus configured to change the suction flow path from the first path to the second path, said suction switching apparatus comprises a connection/disconnection switching mechanism configured to reduce a suction along the first path prior to the suction switching apparatus changing the suction flow path to the second path;
- and
- wherein the first path includes a first end connected to the suction switching apparatus,
- the second path includes a second end connected to the suction switching apparatus, said suction flow path being positionably rotated by a motor having a shaft, so as to selectively engage the first path or the second path, and
- the first end and the second end are located along a circular-arc line around the motor shaft extending in an axial direction.
A punching device, comprising:
- a punching head including a first hollow rod with a first punching tool and a second hollow rod with a second punching tool;
- a first tube connected to the first hollow rod, and the first tube having a first opening at an end;
- a second tube connected to the second hollow rod, and the second tube having a second opening at an end;
- a rotary member having at least one suction opening and at least one sealing member, the rotary member being configured to rotate so as to selectively align the at least one sealing member to close the first opening or the second opening, and align the at least one suction opening to open the other of the first opening or second opening;
- a suction apparatus communicating with the suction opening to define a suction passage with the first or second opening,
- and wherein the first opening and the second opening are positioned on a circular-arc line and the rotary member rotates along the circular arc line.
