Band steel after the preheating of the present invention with some plum blossom flap joint-cutting rolls, offset roller carry out continuously for several times rolling, offset, with the reaming roll of band certain geometrical shape, offset reaming that roller carries out continuously several, offset.
The present invention derusts, again through antirust processing with integer roller several times integer, with after the typing of setting roll several times.
The parallel metal net of any geometry mesh of the present invention, wire netting plane and cross section, it is 0.200-0.618 that unit are includes the metallic area ratio, and the closer to 0.618 coefficient, then the products machinery performance is strong more.
The parallel metal net that the present invention makes can directly enter bonding machine or the plate squeezing machine is compound, and forms metal webmaster or composite board.
Important feature of the present invention is: metal strap is adopted rolling for several times continuously, offsets, be rolling, offset, rolling again, offset ... then through continuous for several times reaming, offset, be reaming, offset, reaming again, offset ... after the operation, the wire netting of making reaches the integral thickness homogeneous, be easy to mechanical shaping, comprehensive mechanical performances such as tension, bending resistance, impact, extension, antiknock are good; In certain wall thickness, increase the thickness of wire netting to greatest extent, improve the comprehensive mechanical performance of multiple tube (plate); Reduced cost of material; The plum blossom lobe quantity of the roll of plum blossom flap and change in size (length and the degree of depth) can change with the metal grill change in size, the reaming roll can be various geometries, and the quantity of the tip of certain geometrical shape and size (width) change with the metal grill change in size; According to metal grill size, shape difference, can arbitrarily change roll, produce the wire netting of different size.
