Manufacturing technology of metal net rack

Abstract

The invention discloses a manufacturing technology of a metal net rack. The manufacturing technology comprises the following steps that primary cutting is conducted, wherein a wire rod raw material ofa first wire rod is cut according to a required length to obtain multiple first wire rods, and a wire rod raw material of a second wire rod is cut according to a length obtained after machining allowance reserving to obtain multiple second wire rods; arranging treatment is conducted, wherein the ends of the multiple first wire rods are aligned and arranged at intervals, the ends of the multiple second wire rods are aligned and arranged at intervals, and the multiple first wire rods and the multiple second wire rods are stacked together in a staggered mode; welding treatment is conducted, wherein the contact positions between the first wire rods and the second wire rods are welded in an electric resistance welding manner, and a semi-finished product is obtained; flattening treatment is conducted, wherein rolling and flattening are conducted on the semi-finished product through a roller; secondary cutting is conducted, wherein the second wire rods on the semi-finished product are cut neatly according to the needed length; and bending treatment is conducted, wherein the end portions of the second wire rods on the semi-finished product are bent to form bent parts, so that a metal netrack finished product with good flatness is obtained.

Description

technical field [0001] The invention relates to the field of manufacturing and processing, in particular to a manufacturing process of a metal grid. Background technique [0002] Such as figure 1 A metal mesh frame is shown, which mainly includes a plurality of first wires 10 and a plurality of second wires 20, the plurality of first wires 10 and the plurality of second wires 20 are alternately arranged and welded, and the second wires 20 Both sides also need to process the bent portion 21, because the diameter size of the wire material selected by the first wire 10 is between 1.4 millimeters and 2 millimeters, the diameter size of the wire material selected by the second wire 20 is 0.9 Between mm and 1.5 mm, the first wire 10 and the second wire 20 are wires with a relatively small diameter. When welding, the first wire 10 and the second wire 20 are prone to obvious bending deformation due to heating. As a result, after the welding of the metal grid frame is completed, th...

[0002] like figure 1 A metal mesh frame is shown, which mainly includes a plurality of first wires 10 and a plurality of second wires 20, the plurality of first wires 10 and the plurality of second wires 20 are alternately arranged and welded, and the second wires 20 Both sides also need to process the bent portion 21, because the diameter size of the wire material selected by the first wire 10 is between 1.4 millimeters and 2 millimeters, the diameter size of the wire material selected by the second wire 20 is 0.9 Between mm and 1.5 mm, the first wire 10 and the second wire 20 are wires with a relatively small diameter. When welding, the first wire 10 and the second wire 20 are prone to obvious bending deformation due to heating. As a result, after the welding of the metal grid frame is completed, the flatness of the finished product is poor
