A laser processing apparatusincludes: a laser head H; a head driving mechanism that moves the laser head H above a workpiece W; and a dust collecting boxthat moves below the workpiece W and follows the laser head H. A non-contact support unitis provided at an openingof the dust collecting box, and the non-contact support unitsuctions a lower surface of the workpiece W toward a suction surfaceand supports the workpiece W without bringing the lower surface of the workpiece W and the suction surfaceinto contact with each other. An outer support rollerand an inner support rollerthat 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

Laser processing apparatus

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.

Laser processing apparatus and laser processing method

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 elementfrom a metal band platewhile applying a counter load by a counter punch

Work-punching device, work-punching method, and method for producing element for continuously variable transmission

Disclosed is a method for manufacturing an element for a CVT belt, comprising a body portion (L,R) having right and left sides and a tapered portion with a downwardly reducing width, a neck portion extending upward from the body portion, and a head portion extending upward from the neck portion. The manufacturing method comprises a first punching step in which a metal strip blank () which has a uniform thickness and a width which makes it possible obtain elements arrayed on an even number of lines in an arrangement in which the head portions are opposed to each other or an arrangement in which the body portions are opposed to each other, is punched along an outline ((L,R) of an excess material () added to profiles of the left and right sides (L,R) of the body portions, and along an outline (L,R) of an excess material () added to a profile of a lower side (L,R) of the body portion; a plastic deformation step in which the blank is compressed in the thickness direction to form a predetermined projection and depression, and form the tapered portion while displacing the material in the outline directions; and a second punching step in which the element is obtained as a product by punching the blank.
