Description

  The present invention relates to a method for producing expanded metal.

  Conventionally, as a method for manufacturing expanded metal from a metal plate, a metal plate is cut between two rolls having blades on the surface, and a metal plate is cut parallel to the width direction of the metal plate. A method of continuously forming a mesh by stretching the cut portion by pulling in a direction perpendicular to the surface has been performed. However, this method has a drawback that it is difficult to spread the mesh uniformly.

  In order to improve the above-mentioned problems of the conventional method, a metal plate is placed between a fixed lower die having a straight blade and a movable upper die having a corrugated blade and movable up and down with respect to the fixed lower die blade. It is fed in a right angle direction, and the movable upper die is reciprocated up and down to form a cut in the metal plate. At the same time, the cut in the first row provided in advance is formed to form a mesh, and then movable. The upper die is moved horizontally to the left or right alternately by half the pitch of the waveform, and the next reciprocating motion is performed to widen the second row of cuts to form a mesh and simultaneously form the third row of cuts. A method of forming a mesh continuously by repeating forming is disclosed (see Patent Document 1).
