The present invention relates to a method for manufacturing a welded wire mesh and a device for manufacturing the same.

In general, a welded wire mesh is arranged in a state in which horizontal wires are arranged in a direction perpendicular to a plurality of vertical wires supplied in a vertical direction, and these vertical wires and horizontal wires are arranged in a right angle with each other. It is manufactured by performing spot welding using a resistance. Such a welded wire mesh is called a square welded wire mesh since the horizontal wire and the vertical wire are arranged in a right angle with each other in a completed state and have a rectangular shape.

Since the rectangular welded wire mesh is electrically welded in the state in which the horizontal wire and the vertical wire are orthogonal to each other, a very strong wire mesh is formed, and its tensile strength and bending strength are much higher than those of the Gabion wire mesh made of iron wire of the same thickness. There is an excellent advantage, because the horizontal and vertical wires are welded in a state arranged in a right angle to each other, the finished wire mesh provides an orderly appearance with a number of rectangles, and gives a very neat and orderly feeling.

In this case, the horizontal wire 20 may be a main horizontal wire 22 or a sub horizontal wire 25 according to each step. Since the electric resistance welding method is only common in the art, a detailed description thereof will be omitted.

In the present invention, a process in which the main horizontal wire 22 and the vertical wire 10 are welded to each other will be described below.

First, a plurality of vertical wires 10 are drawn out to the rear by the vertical wire lead-out unit 110, the horizontal wire 20 by the horizontal wire supply unit 120 is the vertical wire 10 When placed in a direction perpendicular to the, the control unit (C) to operate the wire welding unit 140. To this end, when the welding cylinder 146 is operated in the control unit C, the upper electrode 142 is lowered down. When fully lowered downward, the upper electrode 142 is pressed over the main barbed wire (22).

According to the present invention, the main horizontal wire 22 and the lower vertical wire 10 are positioned between the upper welding rod 142 and the lower welding rod 152 in the state, and they are pressed completely in contact with each other. Is given. At this time, the control unit (C) is to apply the electric current of the high current to the upper electrode 142, the main horizontal wire 22 and the vertical wire (10) by the high current of the electric energy. Electrical welding is performed at the contacts.

In the present invention, the control unit (C) after the electric welding the main horizontal wire 22 and the vertical wire 10, the upper welding rod 142 using the welding cylinder 146 upwards Will be lifted.

Subsequently, the present invention is implemented to the electric welding step (S 320) of the sub-horizontal wire.

2). Electric welding step of sub horizontal wire (S 320):

The method for manufacturing a welded wire mesh according to the present invention includes an electric welding step (S 320) of a sub-horizontal wire for electric welding the sub-horizontal wire 25 on the plurality of longitudinal wires 10.

On the other hand, the control unit (C) after the electric welding the main horizontal wire 22 with respect to the vertical wire (10), and then operates the stationary motor 112, the vertical wire lead-out portion 110 By operating the, and withdraw the vertical wire 10 to send to the rear (in the case of Figure 4, the left), the electric welding is completed to send the wire mesh to the rear. The principle and the operation relationship of sending the vertical wire 10 to the back is the same as described above.

In the present invention, the second hydraulic cylinder 132 is connected to the second rotary shaft 134, the second rotary shaft 134 is connected to the second wire wheel 136. When the second hydraulic cylinder 132 extends and extends the arm, the first wire wheel 136 is rotated in the forward direction, and when the second hydraulic cylinder 132 reduces the arm, the second hydraulic cylinder 132 extends the arm. To rotate the second wire wheel 136 in the reverse direction. In addition, the second wire wheel 136 is preferably formed with a "U" groove 137 on its surface. The U-shaped groove 137 is formed so as to saddle the sub-horizontal wire 25 guided thereon one by one. In the present invention, the second hydraulic cylinder 132 may also be used in place of a pneumatic cylinder.

In addition, the principle of electric welding the sub horizontal wire 25 to the vertical wire 10 and its operation relationship are similar to those described above.

In the present invention, when the vertical wire 10 is sent to the rear, in that state, the control unit C operates the sub horizontal wire supply unit 120B. In more detail, the control unit C extends the second hydraulic cylinder 132 to extend the second rotation shaft 134 connected thereto, thereby extending the second wire wheel 136. Rotate in this forward direction. At this time, since the sub-horizontal wire 25 at the bottom thereof is settled in the “U” shaped groove 137 formed on the surface of the second wire wheel 136, the sub-horizontal wire 25 is pushed downward with its forward rotation, and guides. Guided by the rod 138, it comes to the position of the lower electrode 152. In this state, the upper electrode 142 is lowered to the position of the lower electrode 152, is subjected to a high current of electrical energy from the outside, the electrical welding is performed. When the electric welding is completed, the welding wire mesh is sent back to the back, which principle has already been described above.

3). Repeated steps of electric welding (S 330):

The method of manufacturing a welded wire mesh according to the present invention includes a step of repeating electric welding (S 330).

In the present invention, the repeating step of electric welding (S 330) is the number of sub-horizontal wire 25 used in the electrical welding step (S 320) of the sub-horizontal wire and the sub input to the control unit (C) The number of horizontal wires is compared, and if the compared values are different from each other, the electric welding step (S 320) of the sub horizontal wires is repeatedly performed.

Therefore, in the present invention, for example, when the operator sets and inputs the number of the sub horizontal wires 25 to the control unit C, the electric welding step S 320 of the sub horizontal wires is only 1. Only do it once and proceed to the next step. In this case, the welded wire mesh is formed by repeatedly arranging one main horizontal wire 22 and one sub horizontal wire 25.

However, when the operator sets and inputs the number of the sub horizontal wires 25 to the control unit C, the electric welding step S 320 of the sub horizontal wires is performed twice, and then The process then proceeds. Therefore, the welded wire mesh has a form in which one main horizontal wire 20 and two sub horizontal wire 25 are repeatedly arranged.

Similarly, when the operator sets and inputs the number of the sub horizontal wires 25 to the control unit C, the electric welding step S 320 of the sub horizontal wires is performed three times. After that, the process proceeds. In this case, the welded wire mesh substantially forms a state in which one main horizontal wire 22 and three sub horizontal wire 25 are repeatedly arranged.

In this case, in the welding wire mesh, the welding method for the vertical wire 10 of the main horizontal wire 22 and the sub horizontal wire 25 is the same as described above, and thus, a detailed description thereof will be omitted.

On the other hand, by welding the above-described sub barbed wire 25 in this manner or by repeatedly welding, if the number of the sub barbed wire inputted by the operator to the control unit C is equal to the number of the control unit ( C) to proceed to the electric welding step (S 310) of the main horizontal wire.

In the present invention, the electric welding step (S 310) of the main horizontal wire is carried out as described above. Therefore, the detailed description thereof will be referred to the above description, it will be omitted.

4). Cutting step of the welded wire mesh (S 340):

The present invention preferably further includes a cutting step (S 340) of the welded wire mesh for cutting the welded wire mesh with a cutting knife when the manufactured length of the welded wire mesh is matched with each other compared with the length previously input by the operator. .

In the present invention, the operator can input the cutting length of the welded wire mesh in advance to the control unit (C), in which case the cutting knife 172 is centered around the manufactured length of the square welded wire mesh (200) The square welded wire mesh 200 is automatically cut. In the welded wire mesh, the cutting method of the welded wire mesh by the cutting knife 172 may be performed in a conventional manner. For example, the operator can cut the cutting length of the welded wire mesh into lengths of 1 meter, 2 meters, 3 meters, 5 meters, 10 meters, etc. as necessary. In addition, the operator can set the length to be processed to 1.1 meters, 2.15 meters, 5.2 meters, etc., and it is preferable to cut including the processing length.

In the present invention, when going through the above series of steps, it is preferable to finish and finish the manufacturing process of the welded wire mesh. In the present invention, it is preferable to initialize all the conditions or set values of the control unit C in the end step.

In the present invention, the electric welding step (S 320) of the sub-rail wire is drawn out the length (d ₂ ) of the drawn length (10) of the longitudinal wire 10 in the electric welding step (S 310) of the main barbed wire It may be formed with the same or different length compared to the length (d ₁ ), which will be specifically determined according to the setting value input to the control unit (C). The drawn length d ₁ (d ₂ ) of the vertical wire determines the length of arrangement of the horizontal wires 22 and 25 of the welded wire mesh. In addition, the horizontal wires 22 and 25 of the welded wire mesh may use products having the same or different diameters.

In addition, the present invention provides an apparatus 100 for manufacturing welded wire mesh, which can manufacture various types of welded wire mesh. Apparatus 100 for manufacturing a welded wire mesh according to the present invention is as described above, and will not be repeated.
