摘要： PROBLEM TO BE SOLVED: To improve the cutting quality of comparatively thick conductive ductive material, in particular the cutting quality and cutting efficiency in the edge regions of stainless steel by detecting the variation of the value of electric resistance between a cutting head and a material to be cut and executing parameter control in a cutting process from this variation. SOLUTION: An electric resistance measuring device 9 is provided between the laser beam cutting head 1 or conductive laser beam nozzle 2 and the material 5 to be worked and connected to the mechanical control (parameter control) part 15 in the cutting process through a computer aided evaluating device 14 together with a capacitive range finder 13. During cutting work, the electric resistance between the laser beam nozzle 2 and the material 5 to be worked is continuously measured and drop of the electric resistance when the maintenance of a required cutting depth of the laser beam 4 becomes difficult is detected with the evaluating device 14. At that time, the presence of the distance between the laser beam nozzle 2 and the material 5 to be worked is also detected with the range finder 13, the relative speed between the laser beam nozzle 2 and material 5 to be worked and the output of the laser beam 4 are lowered so as to recover the electric resistance in a regular cutting work.

摘要： PROBLEM TO BE SOLVED: To avoid inconvenient deformation and damage by arranging opposed bearing parts behind a pair of forming rolls in the feeding direction and supporting them on the side faced to the 2nd thin metallic plate part of the edge part of the thin metallic plate. SOLUTION: With at least one pair 12, 15 of the forming rolls, the edge part 4 of the thin metallic plate provided in a 1st thin metallic plate part 2 is mated with the 2nd thin metallic part 3 and bent. Forming rolls 13, 14, 16, 17 are rolled in the feeding direction along the longitudinal edge on the edge part 4 of the thin metallic plate on the side opposing each other of the edge part 4 of the thin metallic plate and roll gaps are inclined toward the 2nd thin metallic plate part 3 in the bending direction. One of the forming rolls 14, 17 enters under the edge part 4 of the thin metallic plate on the side faced to the 2nd thin metallic plate part 3 and, with at least one opposed bearing part supported to one of the thin metallic plate parts 2, 3, is supported by acting in the crossing direction to the feeding direction 19. The opposed bearing parts are arranged behind the pair 12 of the forming rolls in the feeding direction 19 and supported on the side faced to the 2nd thin metallic plate part 3 of the edge part 4 of the thin metallic plate.

摘要： So that the distance between workpiece and nozzle in laser cutting machines can be detected in a contactless manner, the change in the capacitance is measured. To this end, it is necessary to arrange the electrically conductive metallic nozzle (1) in a receptacle (10) designed as an insulating body, an electrically conductive connection (13, 14) being provided between the nozzle (1) and the measuring device. In order to provide a receptacle (10) which is simple to produce and ensures an easy-running thread and good contact transmission between nozzle (1) and receptacle (10), an insert (4) made of an electrically conductive material, in particular metal, and having the internal thread (6) for the nozzle (1) is inserted into the recess (9).

摘要： PURPOSE: To obtain an industrial laser device constituted only of gas piping with a small output in a simple constitution by providing a square laser optical path on a square base device, and providing a blower for cooling gas at a central lower part. CONSTITUTION: A CO2 laser 11 is attached on a table 12 and forms a square optical path. A turbo radial blower 13 is attached in the lower part of the table center with the vertical axis. A cooling gas is divided into four parts from the lower part of the table center, allowed to enter a partial block 66, cooled by a heat exchanger, allowed to flow to a diagonal direction, resin at a corner part, allowed to enter the optical path 14, parted right and left, allowed to descend downward from the center of a table side part, allowed to enter a partial block 83, cooled, and returned to the blower. The optical path is cooled well by the gas, and the output of a laser is efficiently improved. A table size is about 85cm squares, and table thickness is 50-140mm, and the laser output of 200 - several kilowatts can be obtained.
