Title:
WORKTABLE IN SHEET METAL WORKING MACHINE
Document Type and Number:
Japanese Patent JP2001321860
Kind Code:
A
Abstract:

To provide a worktable in a sheet metal working machine which can ensure the positioning accuracy of a work by preventing the work from being caught and prevent the wear of a brush bundle and the damage of the work.

Since the brush bundle 11 is arranged at a lattice point at which lattice shapes orthogonal to each other are rotated by a predetermined angle, the space can be reduced without increasing the number of the brush bundles 11, long square or long round punched members are prevented from being caught by the bundles 11, and movably supported. Alternatively, the brush bundle 11 is arranged at the position at which the brush bundles 11 arrayed in a zigzag manner are rotated by a predetermined angle. Further alternatively, the worktables 5 and 7 are divided in a plurality of blocks 49 and 51 in the Y-axis direction, and the blocks 49 and 51 adjacent to each other in the Y-axis direction are shifted by half pitch in the X-axis direction.
