As shown in fig. 1 to 3, first, the present embodiment provides a wire mesh including a plurality of wire units 100, each wire unit 100 being bent by reciprocal rotation to form first and second side wires 101 and 102 arranged alternately, peaks 110 and valleys 120 arranged alternately on the wire unit 100 being formed where the plurality of first side wires 101 and the plurality of second side wires 102 meet, the first side wires 101 on the wire unit 100 being located in a first plane, the second side wires 102 on the wire unit 100 being located in a second plane, the peaks 110 and valleys 120 of adjacent wire units 100 being connected together to form a mesh body, a first bending portion being provided at the peak 110 of the wire unit 100, and a second bending portion being provided at the valley 120 of the wire unit 100. Due to the first and second bending portions, a gap is formed between the first and second planes, that is, the thickness formed by the first and second border wires 101 and 102 is greater than the sum of the thicknesses of the first border wire 101 and the second border wire 102. The first bent portion is formed with a first convex angle 111 protruding the second plane, and the second bent portion is formed with a second convex angle 121 protruding the first plane. The first convex angle 111 and the second convex angle 121 can increase the blocking effect of the net body on the target, and when the target leaks out of the holes of the net body, the first convex angle 111 and the second convex angle 121 can increase the friction force of the net body on the target, and increase the adhesion effect of the target.

The wire material of which the wire unit 100 is made is a single wire, a twisted wire, or a helical wire. The strength of the stranded wire is greater than that of the single wire, but the elasticity of the spiral wire is better. In addition, in order to increase the anti-slip performance of the wire unit 100, the surface of the wire unit 100 is covered with a plastic coating.

When the net body is fixed to a protection target, both the first side wire 101 and the second side wire 102 are bent. First silk body and the second silk body of crooked form make the installation adaptability of dictyosome stronger, when meetting the target surface unevenness who treats protection, first silk body and second silk body can be as the compensation for the target surface that the laminating that the dictyosome can be more was treated in the laminating avoids the dictyosome state that too tight appears. Specifically, the first edge wire 101 is bent perpendicularly toward the inside of the first plane, and the second edge wire 102 is bent perpendicularly toward the inside of the second plane.

As mentioned above, the first bent portion and the second bent portion are configured to form a gap between the first plane and the second plane, the gap is formed by the first bent portion having two corners, one corner is the first convex corner 111, and the other corner is the first circular arc corner 112, specifically, the first convex corner 111 and the second circular arc corner 122 protrude from the first plane to form the gap. The second bent portion also has two corners, one of the two corners is the second convex corner 121, and the other corresponding corner is the second arc corner 122. The two corners are arranged such that the first and second lobes 111, 121 are higher than the surface of the mesh body as a whole.

Secondly, this embodiment also discloses a method for manufacturing a screen, which includes the following steps:

s1, rotating and folding the wire material into a corrugated wire unit 100, wherein the corrugated wire unit 100 includes a plurality of first side wires 101 and second side wires 102 which are alternately connected, and when the wire material is alternately folded out of the first side wires 101 and the second side wires 102, a first bending part and a second bending part are formed, and the first side wires 101 and the second side wires 102 of the wire unit 100 are bent;

s2, sequentially rotating, penetrating and connecting the silk thread units 100 prepared in the S1 into a net body;

and S3, connecting the ends of the plurality of wire units 100 on the net body without disengaging.

The wire unit 100 and the net body are formed mainly by means of rotary bending and rotary insertion, and specifically, the wire rod may be processed by using a decorative net with a publication number of CN107008835A and a wire bending machine to form the wire unit and the net body.

In step S1, a bent portion is formed at the connection point of the first side wire 101 and the second side wire 102, and the wire material needs to be bent twice for each bent portion, and when the first bent portion is formed, the first side wire 101 is formed in the wire unit 100, and when the first second bent portion is formed, the first second side wire 102 is formed adjacent to the first side wire 101 in the wire unit 100, and the process is alternately repeated to form a plurality of first side wires 101 and second side wires 102. One of the two bending steps is to bend the wire into an arc angle, and the other corresponding bending step is to bend the wire into a convex angle, so that the wire can be bent twice to form a new first side wire 101 or second side wire 102.
