The steel mesh is formed by orthogonal arrangement of longitudinal main reinforcement and transverse reinforcement. When making steel mesh, the longitudinal main reinforcement and transverse reinforcement need to be connected together by welding the intersection. The welding equipment used is a welding machine. The cross section of the welding machine is as follows Figure 1 As shown, in Figure 1 In the process, the longitudinal main reinforcement 1 passes through the welding device of the welding machine through the positioning device, and the transverse reinforcement 2 is placed on the top of the longitudinal main reinforcement 1 through the feeding device, and then the upper pressure beam 3 is used to press the transverse reinforcement 2 and the longitudinal main reinforcement 1 on the reaction device 4, and finally the cross point of the transverse reinforcement 2 and the longitudinal main reinforcement 1 is welded and connected by resistance pressure welding to achieve the connection between the single longitudinal main reinforcement and the transverse reinforcement.

[0035] Figure 2-7 A schematic diagram of a steel bar clamping device provided by an embodiment of the present invention, see Figure 2 The steel bar clamping device provided in this embodiment is used to make a steel mesh, the steel mesh includes a longitudinal main bar 10 and a transverse steel bar 20, the steel bar clamping device is used to clamp the longitudinal main bar 10, the transverse steel bar 20 is arranged above the longitudinal main bar 10, and is welded perpendicularly to each other. Figure 2 As shown, the steel bar clamping device provided in this embodiment includes a first clamping system 100 , a second clamping system 300 and a steel bar moving track 200 , and the first clamping system 100 and the second clamping system 300 are connected via the steel bar moving track 200 .

[0036] The first clamping system 100 includes a first track 110, a first clamping body 120 and a propulsion device 130. The first clamping body 120 is installed on the first track 110 and can slide along a first direction on the first track 110. The propulsion device 130 is used to drive the first clamping body 120 to slide on the first track 110. The first direction is the extension direction of the longitudinal main rib 10. The first clamping body 120 is used to clamp and drive the longitudinal main rib 10. Figure 3 The first clamping body 120 includes a first upper pressing device 121, a first upper pressing power device 123, a first lower pressing device 122 and a first lower pressing power device 124, wherein the first upper pressing power device 123 and the first lower pressing power device 124 are used to drive the first upper pressing device 121 and the first lower pressing device 122 to move in the second direction, so that the first upper pressing device 121 and the first lower pressing device 122 cooperate with and clamp the longitudinal main rib 10, and the extension direction of the longitudinal main rib 10 is perpendicular to the second direction. Figure 4 The first upper pressing device 121 and / or the first lower pressing device 122 are provided with a limiting structure 30, or the first upper pressing device 121 and the first lower pressing device 122 cooperate to form a limiting mechanism 30 to limit the longitudinal main reinforcement 10, so that when the first upper pressing device 121 and the first lower pressing device 122 are used to clamp the plurality of longitudinal main reinforcements 10, the extension directions of the plurality of longitudinal main reinforcements 10 are parallel to each other and are equally spaced. Figure 2 and Figure 5 The second clamping system 300 includes a second clamping body, and the second clamping body includes a second upper pressing device 310, a second upper pressing power device 330, a second lower pressing device 320 and a second lower pressing power device 340. The second upper pressing power device 330 and the second lower pressing power device 340 are used to drive the second upper pressing device 310 and the second lower pressing device 320 to move in a third direction so that the second upper pressing device 310 and the second lower pressing device 320 cooperate and clamp the steel bar, and the third direction is perpendicular to the extension direction of the steel bar.

[0037] During specific implementation, the first clamping system 100 is used to clamp and drive the longitudinal main reinforcement 10 to move on the reinforcement moving track 200, and the second clamping system 300 is only used to clamp the longitudinal main reinforcement 10. During the production process of the reinforcement mesh, the reinforcement clamping equipment is set on a plane, generally the ground, and the first upper pressure device 121 and the first lower pressure device 122 are driven by the first upper pressure drive device 123 and the first lower pressure drive device 124 to move toward each other perpendicular to the equipment placement plane to clamp the plurality of longitudinal main reinforcements 10. Due to the existence of the limiting mechanism 30, each limiting mechanism 30 can be used to clamp and accommodate one longitudinal main reinforcement 10, and the extension directions of the plurality of longitudinal main reinforcements 10 are parallel and equally spaced. The limiting mechanism 30 can also be used to clamp a group of multiple longitudinal main reinforcements 10, such as a group of two, and the limiting mechanism 30 can make the extension directions of each group of longitudinal main reinforcements 10 parallel and equally spaced. Figure 7 As shown, the limiting mechanism 30 may include an inclined pressure head 31 and a blocking pressure head 32. The left side of each steel bar is positioned on the left side by relying on the blocking pressure head 32, and the right side of each steel bar uses the inclined surface of the inclined pressure head 31 to squeeze the steel bar from right to left to achieve the right side positioning of the steel bar. For example, when the longitudinal main reinforcement 10 is a single reinforcement, the spring is compressed, and the inclined pressure head 31 squeezes the single reinforcement against the blocking pressure head 32 to achieve the compression and positioning of the single reinforcement; when the longitudinal main reinforcement 10 is two steel bars, one thick and one thin, arranged side by side, the inclined pressure head 31 squeezes the thin steel bar against the thick steel bar, and finally squeezes it against the blocking pressure head 32.

[0038] The second upper pressing device 310 and the second lower pressing device 320 are driven by the second upper pressing driving device 330 and the second lower pressing driving device 340 to move toward each other perpendicular to the equipment placement plane, clamping a plurality of the longitudinal main bars 10 and welding a portion of the transverse steel bars 10. After the welding is completed, the entire semi-finished steel mesh needs to be moved to vacate the welding position. At this time, the clamping of the second clamping system 300 is released, and the propulsion device 130 is turned on. Figure 2As shown, the propulsion device 130 drives the first clamping body 120 to move leftward in the extension direction of the longitudinal main reinforcement 10. Since the first clamping body 120 continues to clamp the longitudinal main reinforcement 10, the first clamping body 120 drives the longitudinal main reinforcement 10 to move leftward on the reinforcement moving track 200 when moving leftward, forming a new welding position, and continuing to weld the transverse reinforcement 20. This is then repeated until the reinforcement mesh is completed.

[0039] The steel bar clamping device provided in this embodiment uses a two-end clamping method, and can perform cross-point welding when using a common welding gun. When the steel mesh is pushed longitudinally, the second clamping system 300 is released, the first clamping system 100 is maintained, and the steel mesh is driven by the first clamping body 120 to move longitudinally under the push of the pushing device 130. In addition, the steel bar clamping device provided by the present invention uses a fixed positioning device to achieve the parallel placement of the longitudinal main bars 10 at equal intervals.

[0040] See also Figure 6 The first steel bar body 120 of the steel bar clamping device provided in one embodiment of the present invention includes a first upper pressing device 121, a first lower pressing device 122, a first upper pressing power device 123 and a first lower pressing power device 124. The first upper pressing device 121 includes a first upper pressing beam 121a and a plurality of first upper pressing heads 121b arranged on the first upper pressing beam 121a. The first lower pressing device 122 includes a first lower pressing beam 121a and a plurality of first lower pressing heads 121b arranged on the first lower pressing beam 121a. And, as Figure 6 As shown, the first upper pressing beam 121a and the first lower pressing beam 121b correspond to each other, and the first upper pressing head 121b and the first lower pressing head 122b thereon correspond to each other. In addition, the intervals between the first upper pressing heads 121a and the first lower pressing heads 121b are equal, and the corresponding two first upper pressing heads 121a and the first lower pressing heads 121b form a limiting structure 30 when pressing the longitudinal main rib 10, so as to limit the longitudinal main rib 10. Considering the symmetry, the first upper pressing power device 123 and the first lower pressing power device 124 are generally two in number, which are respectively arranged at the two ends of the first upper pressing beam 121a and the first lower pressing beam 122a to drive the first upper pressing beam 121a and the first lower pressing beam 122a to move. The first upper pressing power device 123 and the first lower pressing power device 124 generally adopt oil cylinders.

[0041] The first clamping body 120 is provided with sliders 110a at both ends. Figure 6Two sliders 110a are arranged at both ends of the first pressing beam 122a, and the two sliders 110a can slide in the first track 110, so that the entire first clamping body 120 can slide along the first track 110. The steel bar conveying track 200 is often configured as a rolling track including a plurality of rollers, and the sliding of the longitudinal main bar 10 on the rollers is a sliding mode with relatively low friction, which is conducive to the movement of the longitudinal main bar 10.

The steel mesh manufacturing device realizes the automation of the steel mesh manufacturing process.

[0043] In order to achieve symmetrical and neat specifications of the steel mesh, when the steel bar feeding and welding equipment 400 sets the transverse steel bars 20 on the longitudinal main bars 10, the spacing of the transverse steel bars 20 is equal and equal to the spacing between the longitudinal main bars 10. Since the second clamping system 300 needs to press the semi-finished steel mesh during the steel mesh production process, the second clamping system 300 is configured to cooperate with each other to clamp the mesh structure formed by welding the longitudinal main bars 10 and the transverse steel bars 20.

[0050] S6: Repeat step S4 and step S5 until the welding of the steel mesh is completed.

[0051] The steel bar clamping device provided by the present invention uses a two-end clamping method, which has the advantage of performing cross-point welding using an ordinary welding gun. When the steel mesh is pushed longitudinally, the second clamping system is released, the first clamping system is maintained, and the steel mesh is driven by the first clamping system to move longitudinally under the push of the propulsion device. In addition, the steel bar clamping device provided by the present invention uses a fixed positioning device to achieve parallel placement of longitudinal main bars at equal intervals.
