[0001] The invention relates to a welding machine and a welding method, and in particular to a steel mesh cage welding machine and a welding method. Background Art

[0002] Large-sized autoclaved aerated concrete blocks or panels need to be equipped with steel mesh cages as keels to enhance the strength and toughness of the autoclaved aerated concrete blocks or panels. For example, the plate mesh cage disclosed in the patent application with the announcement number CN110076508A includes: a mesh cage body, the upper part of the mesh cage body is connected to a plurality of upper connecting plates along the length direction, and the lower part of the mesh cage body is connected to a plurality of lower connecting plates along the length direction. There is an existing mesh cage, which replaces the connecting plates of the plate mesh cage with short bars (short steel bars) to reduce costs. The short bars are connected between the stacked mesh plates (equivalent to the mesh cage body) by welding.

[0003] Patent applications with announcement numbers CN110076508A and CN110355456A also disclose a steel mesh cage space multi-spot welding machine, which includes a frame, a transformer, an upper welding assembly, an upper sheet taking assembly, a lower sheet taking assembly and a lower welding assembly; the transformer is arranged on the frame, and the transformer is connected to the upper welding assembly and the lower welding assembly through a wiring harness; the upper welding assembly and the lower welding assembly are arranged axially symmetrically, the upper sheet taking assembly cooperates with the upper welding assembly, and the lower sheet taking assembly cooperates with the lower welding assembly; the upper sheet taking assembly and the lower sheet taking assembly grab and fix the connecting piece, and assist the upper welding assembly and the lower welding assembly to complete the four-point simultaneous welding operation. It can weld the above-mentioned sheet mesh cage so that the connecting piece is welded to the mesh cage body.

[0004] Although the above-mentioned mesh cage space multi-spot welding machine can weld the connecting piece and the mesh cage body, the structure of the mesh cage space multi-spot welding machine has the following defects: 1. It cannot make adaptive adjustments according to the length of the connecting piece and the height of the mesh cage body. When the length of the connecting piece and the height of the mesh cage body need to be adjusted, the entire machine with a new size design needs to be replaced, resulting in the mesh cage space multi-spot welding machine not having universal applicability; 2. When welding, it can only weld the mesh cage bodies placed vertically side by side, and cannot weld the stacked mesh sheets. Therefore, it is necessary to redesign it to solve the above problems.

DETAILED DESCRIPTION

[0040] The steel mesh cage welding machine is composed of a base 1, a transverse adjustment screw rod 2 and a welder. The base 1 is provided with slide rails 3 in parallel, and welders are symmetrically installed at both ends of the slide rails 3. The base outside the welder is threadedly installed with a transverse adjustment screw rod 2, and the end of the transverse adjustment screw rod 2 is connected to the welder. The function of the transverse adjustment screw rod 2 is to drive the welder to move on the slide rail 3 through the rotation of the transverse adjustment screw rod 2, and then adjust the spacing between the welders at both ends of the slide rail 3 and the position of the welder on the base, so that the space between the welders can correspond to the conveying device for conveying the mesh and the spacing between the welders can be adapted to the width of the mesh, so that the mesh can be conveyed between the welders for welding, and it is ensured that the mesh will not interfere with the welder during the conveying process.

[0041] The welder is composed of an assembly seat 4, a short rib feeding mechanism, a flip feeding mechanism, a lower welding head 5 and an upper welding head. The assembly seat 4 is provided with a short rib feeding mechanism, so that the short ribs to be welded are fed one by one through the short rib feeding mechanism, so that the short ribs can be welded one by one. The assembly seat 4 inside the short rib feeding mechanism is provided with a flip feeding mechanism, so that the short ribs are fed between the meshes through the flip feeding mechanism, so that the short ribs can contact the mesh in space, thereby enabling the short ribs to be welded to the meshes. A lower electrode cylinder 6 is provided on the assembly seat 4 above the short rib blanking mechanism, and a lower welding head 5 is fixedly installed on the end of the piston rod of the lower electrode cylinder 6. The end of the piston rod of the lower electrode cylinder 6 is insulated and connected to the lower welding head 5, and the lower welding head 5 is electrically connected to the power supply; the function of the lower electrode cylinder 6 is to push the lower welding head 5 to move during the extension of the piston rod of the lower electrode cylinder 6, so that the lower welding head 5 can contact the mesh at the lower end, so that a current is formed between the lower end mesh and the short ribs. Since the cross-sections of the steel bars and the short ribs of the mesh are both circular, the contact surface of the steel bars of the mesh is small when they are in contact with the short ribs. After the mesh and the short ribs are conductive, a large current is formed between the contact points of the steel bars of the mesh and the short ribs, so that the temperature between the contact points of the steel bars of the mesh and the bottom ends of the short ribs rises rapidly, thereby melting the contact points of the steel bars of the mesh and the short ribs, so that the mesh and the short ribs are welded into shape. An upper electrode cylinder 7 is provided on the assembly seat 4 above the lower welding head 5. An upper welding head is installed on the piston rod end of the upper electrode cylinder 7. The upper welding head is insulated and connected to the piston rod end of the upper electrode cylinder 7, and the upper welding head is electrically connected to the power supply. The function of the upper electrode cylinder 7 is to push the upper welding head to move so that the upper welding head can contact the upper mesh, so that the upper mesh can be conductive with the top end of the short rib, thereby welding the upper mesh and the top end of the short rib. The assembly seat 4 is slidably connected to the slide rail 3 and is movably connected to the end of the lateral adjustment screw 2 through the bearing seat, so that the assembly seat 4 can be driven to slide on the slide rail 3 during the rotation of the lateral adjustment screw 2, thereby driving the welder to slide on the slide rail 3 to adjust the position of the welder.

[0042] The short reinforcement cutting mechanism is composed of a support frame, a positioning base plate 8, a bottom support 9, a root limiting plate 10 and a top rod 11. A positioning base plate 8 is arranged at the bottom of the support frame, and bottom supports 9 are arranged at intervals on the support frame above the positioning base plate 8. The end of the bottom support 9 at the top of the support frame is bent upward, and the bottom support 9 at the bottom of the support frame is bent downward, and the bottom support 9 between the bending parts is inclined; a root limiting plate 10 is arranged above the bottom support 9, and the root limiting plate 10 is arranged at intervals from the bottom support 9. The function of the root limiting plate 10 is that the root limiting plate 10 and the bottom support 9 cooperate to limit the space above the bottom end of the bottom support 9, so that the distance between the bottom end of the bottom support 9 and the root limiting plate 10 can only accommodate a single short reinforcement to pass through, and then the short reinforcements are cut one by one, so that the short reinforcements can fall on the positioning base plate 8 one by one. The end of the positioning base plate 8 is equipped with a push rod 11 through a rodless cylinder 12. The function of the rodless cylinder 12 is to drive the push rod 11 to move, so that the push rod 11 can push the short rib to move, and then the short rib is transferred outward by the short rib feeding mechanism. The function of the positioning base plate 8 is to position the short rib through the positioning base plate 8 in cooperation with the bottom support and the root limiting plate 10, so that the end of the push rod 11 can accurately abut against the end of the short rib on the positioning base plate 8, thereby ensuring that the push rod 11 can push the short rib to transfer.

[0043] The support frame is composed of a supporting base plate 13, a positioning side plate 14 and a supporting side plate 15. The inner end of the supporting base plate 13 is provided with a positioning side plate 14, and the outer end of the supporting base plate 13 is provided with a supporting side plate 15; the positioning side plate 14 and the supporting side plate 15 are respectively fixedly connected to the assembly seat 4; the bottom bracket 9 on one side of the positioning side plate 14 is fixedly connected to the supporting base plate 13 by fixing bolts; the limited length plate 16 is installed on the bottom bracket 9 on one side of the supporting side plate 15 by fixing bolts. The function of the length limiting plate 16 is to cooperate with the positioning side plate 14 to limit the outer side of the bottom bracket 9 to prevent the short ribs from sliding off the outer side of the bottom bracket 9. At the same time, the short ribs are restricted by the length limiting plate 16 and the positioning side plate 14 to regularize the short ribs and align the ends of the short ribs, thereby ensuring that the ends of the short ribs are in the same position when the short ribs are cut onto the positioning bottom plate 8. Therefore, the restrictions of the length limiting plate 16, the positioning side plate 14, the positioning bottom plate 8, the root limiting plate 10 and the bottom bracket 9 ensure that the short ribs on the positioning bottom plate 8 correspond to the positions of the push rod 11, thereby ensuring that the push rod 11 can push the short ribs to transfer.

[0044] The positioning side plate 14 and the length limiting plate 16 are respectively provided with root limiting strip holes 17 for adjusting the distance between the root limiting plate 10 and the base 9. The positioning side plate 14 and the length limiting plate 16 are respectively fixedly connected to the root limiting plate 10 through the root limiting strip holes 17 and fixing bolts, that is, the root limiting plate 10 on one side of the positioning side plate 14 is connected to the positioning side plate 14 through the root limiting strip holes 17 and fixing bolts, and the root limiting plate 10 on one side of the length limiting plate 16 is connected to the length limiting plate 16 through the root limiting strip holes 17 and fixing bolts. The function of the root limiting strip hole 17 is to adjust the distance between the base 9 and the root limiting plate 10, so that the distance between the bottom end of the base 9 and the root limiting plate 10 can just allow short bars of equal thickness to enter, and then the short bars can only enter between the bottom end of the base 9 and the root limiting plate 10 one by one, thereby cutting the short bars one by one; at the same time, by adjusting the position of the root limiting plate 10 through the root limiting strip hole 17, the distance between the bottom end of the base 9 and the root limiting plate 10 can be adapted to the diameter of the short bars, thereby increasing the universality of the short bar cutting mechanism.

[0045] The support bottom plate 13 is provided with limited length strip holes 18 in parallel, and the support bottom plate 13 is fixedly connected to the bottom bracket 9 on one side of the length limiting plate 16 through the limited length strip holes 18 and the fixing bolts. The role of the limited length strip holes 18 is to adjust the position of the bottom bracket 9 on one side of the length limiting plate 16. In the process of adjusting the position of the bottom bracket 9, the positions of the length limiting plate 16 and the root limiting plate 10 can be adjusted at the same time, so that the positions of the bottom bracket 9, the length limiting plate 16 and the root limiting plate 10 are adapted to the length of the short ribs.

[0046] A positioning groove 19 is provided on the positioning base plate 8 between the root limiting plate 10 and the bottom bracket 9, and the positioning groove 19 is slidably connected with the top rod 11, so as to position the short ribs through the positioning groove 19, further ensure the position of the short ribs, so that the top rod 11 can push the end of the short ribs, and then push the short ribs to move. Transverse adjustment slides 20 are respectively provided on the positioning base plate 8 on both sides of the positioning groove 19, and the transverse adjustment slides 20 below the positioning groove 19 are respectively slidably connected with the positioning side plate 14, the bottom bracket 9, the length limiting plate 16 and the supporting side plate 15, and the transverse adjustment slides 20 above the positioning groove 19 are respectively slidably connected with the positioning side plate 14, the length limiting plate 16 and the supporting side plate 15; the bottom of the transverse adjustment slides 20 is evenly distributed with transverse adjustment holes 21, and the positioning side plate 14, the bottom bracket 9, the length limiting plate 16 and the supporting side plate 15 are respectively fixedly connected with the positioning base plate 8 through the transverse adjustment holes 21 and fixing bolts. The function of the lateral adjustment groove 20 is to position and support the positioning base plate 8 with the positioning side plate 14, the bottom bracket 9, the length limiting plate 16 and the supporting side plate 15 respectively through the lateral adjustment groove 20, thereby limiting the relative position between the bottom ends of the positioning side plate 14, the bottom bracket 9, the length limiting plate 16 and the supporting side plate 15 and the positioning base plate 8.

[0047] A disturbance shaft 22 is movably installed between the positioning side plate 14 and the supporting side plate 15 through a bearing. The end of the disturbance shaft 22 passes through the supporting side plate 15, the length limiting plate 16, and the root limiting plate 10 in sequence and extends to the outside of the positioning side plate 14. The root limiting plate 10 is provided with an adjustment hole, and the disturbance shaft 22 passes through the root limiting plate 10 through the adjustment hole to avoid interference between the root limiting plate 10 and the disturbance shaft 22, which causes the root limiting plate 10 to be unable to adjust. A disturbance cylinder 23 is hinged on the outside of the positioning side plate 14, and the piston rod end of the disturbance cylinder 23 is connected to the end of the disturbance shaft 22 extending to the outside of the positioning side plate 14 through a connecting rod A24; a disturbance plate 25 is installed on the disturbance shaft 22 between the root limiting plates 10 through a fixing bolt, and the bottom end of the disturbance plate 25 extends to the top of the positioning bottom plate 8. The function of the disturbance cylinder 23 is to drive the disturbance shaft 22 to swing through the connecting rod A24, and then drive the disturbance plate 25 to swing, so that the disturbance plate 25 can disturb the short ribs between the bottom support 9 and the root limiting plate 10, thereby ensuring that the short ribs can be cut normally. Since the disturbance plate 25 is connected to the disturbance shaft 22 by fixing bolts, the position of the disturbance plate 25 on the disturbance shaft 22 can be adjusted when the fixing bolts are loosened to avoid interference between the disturbance plate 25 and the root limiting plate 10.

[0048] The flipping feeding mechanism is composed of a lifting cylinder 26, a magnetic support plate 27, an electrode conduction plate 28, a magnetic flap 29 and a flipping cylinder 30. The piston rod end of the lifting cylinder 26 arranged on the assembly seat 4 is fixedly equipped with an assembly plate 31, which is L-shaped. The top end of the assembly plate 31 is installed with a magnetic support plate 27, and an electrode conduction plate 28 is arranged on the magnetic support plate 27. The electrode conduction plate 28 and the magnetic support plate 27 are insulated. The magnetic flap 29 is movably installed on the assembly seat 4 below the magnetic support plate 27 through a short axis. The flipping cylinder 30 is hinged on the assembly seat 4 below the magnetic flap 29, and the piston rod end of the flipping cylinder 30 is hinged with the magnetic flap 29. The function of the flipping cylinder 30 is to drive the magnetic flap 29 to swing, and then drive the short ribs on the magnetic flap 29 to swing, so that the short ribs can be switched from a horizontal state to a vertical state during the swinging process, and at the same time, the short ribs are transferred to the electrode conduction plate 28 during the swinging process. The function of the lifting cylinder 26 is to drive the magnetic support plate 27 to lift through the assembly plate 31, and then drive the electrode conduction plate 28 and the short ribs on the electrode conduction plate 28 to lift, so that the short ribs can move between the meshes, thereby enabling the short ribs to be welded with the meshes; at the same time, after the welding is completed, the magnetic support plate 27 and the electrode conduction plate 28 can be reset by resetting the lifting cylinder 26, so that the magnetic support plate 27 and the electrode conduction plate 28 will not interfere with the mesh, so that the mesh can be normally transmitted forward. The magnetic support plate 27 and the magnetic flap 29 are respectively magnetic, so that the magnetic support plate 27 and the magnetic flap 29 can respectively fix the short ribs through magnetism, thereby driving the short ribs to transfer; and the magnetic support plate 27 is greater than the magnetic force of the magnetic flap 29, so that when the magnetic flap 29 drives the short ribs to transfer to the electrode conduction plate 28, the magnetic force of the magnetic support plate 27 can transfer the short ribs from the magnetic flap 29 and adsorb them on the electrode conduction plate 28. The electrode conduction plate 28 can also conduct electricity to the upper welding head and the lower welding head 5, so that a closed current loop can be formed between the upper welding head, the lower welding head 5, the electrode conduction plate 28 and the power supply, thereby welding the short ribs and mesh between the lower welding head 5 and the electrode conduction plate 28 and between the upper welding head and the electrode conduction plate 28.

[0049] Guide wheels 32 are respectively provided on the end faces and sides of the magnetic support plate 27 on both sides of the electrode conduction plate 28. The guide wheels 32 are movably connected to the assembly seat 4 through a short shaft and are slidably connected to the magnetic support plate 27, so as to limit the position of the magnetic support plate 27 through the guide wheels 32 to prevent the magnetic support plate 27 from shifting during movement, thereby limiting the position of the electrode conduction plate 28 and the short ribs to prevent the electrode conduction plate 28 and the short ribs from shifting during movement.

[0050] The electrode conducting plate 28 and the magnetic flap 29 are respectively provided with longitudinal limiting grooves 33 to limit the position of the short ribs through the longitudinal limiting grooves 33 so that the short ribs can be accurately transferred and welded. The longitudinal limiting grooves 33 on the electrode conducting plate 28 can also increase the contact area between the electrode conducting plate 28 and the short ribs, thereby reducing the current between the electrode conducting plate 28 and the short ribs and preventing the electrode conducting plate 28 from welding with the short ribs.

[0051] A support frame 34 for supporting the top end of the magnetic support plate 27 is provided on the assembly seat 4 above the magnetic support plate 27. The function of the support frame 34 is to cooperate with the assembly seat 4 to support the magnetic support plate 27, so that the magnetic support plate 27 can withstand lateral impact, thereby enabling the electrode conduction plate 28 to withstand lateral impact, so that the electrode conduction plate 28 can clamp the mesh and short ribs between the electrode conduction plate 28 and the upper welding head and between the electrode conduction plate 28 and the lower welding head 5.

[0052] The upper welding head is composed of a long strip-shaped support block 35 and a sliding electrode 36. The support block 35 is provided with longitudinal adjustment slots 37 in parallel. The sliding electrode 36 is mounted on the longitudinal adjustment slots 37. The longitudinal adjustment slots 37 are provided with longitudinal adjustment holes 38 on both sides. The support block 35 is fixedly connected to the sliding electrode 36 through the longitudinal adjustment holes 38 and the fixing bolts. The support block 35 is insulated and connected to the piston rod end of the upper electrode cylinder 7. The sliding electrode 36 is electrically connected to the power supply through the support block 35. The function of the longitudinal adjustment slot 37 is to adjust the position of the sliding electrode 36, thereby adjusting the spacing between the sliding electrode 36 and the lower welding head 5, so that the spacing between the sliding electrode 36 and the lower welding head 5 can be adapted to the spacing between the meshes. The upper welding head clamps the mesh and the short ribs through the sliding electrode 36, thereby making the sliding electrode 36, the mesh and the short ribs conductive.

[0053] The sliding electrode 36 and the lower welding head 5 are respectively mounted with guide plates 39 by fixing bolts, and the ends of the guide plates 39 extend to both sides of the sliding electrode 36 or the lower welding head 5 and bend inwards, and the ends of the guide plates 39 are respectively provided with positioning guide grooves 40. The function of the guide grooves 40 is to guide the mesh through the guide grooves 40 so that the mesh can move to the middle of the sliding electrode 36 and the lower welding head 5, thereby ensuring the connection between the mesh and the sliding electrode 36 and the lower welding head 5, thereby ensuring the conduction between the mesh and the sliding electrode 36 and the lower welding head 5.

[0054] Transverse limiting grooves 41 are respectively arranged on the end faces of the sliding electrode 36 and the lower welding head 5. The function of the transverse limiting grooves 41 is, on the one hand, to limit the position of the mesh, and on the other hand, to increase the contact area between the sliding electrode 36 or the lower welding head 5 and the mesh, thereby reducing the current between the sliding electrode 36 or the lower welding head 5 and the mesh, and preventing the sliding electrode 36 or the lower welding head 5 from welding to the mesh.

[0055] An end straightener is provided on the assembly seat 4 between the upper welding head and the short rib blanking mechanism, so as to straighten and position the end of the mesh through the end straightener. The end straightener is composed of a positioning shaft 42, a support guide rod 43 and a positioning guide plate 44. The positioning shaft 42 is movably installed on the assembly seat 4 through a bearing seat, and the support guide rod 43 is installed up and down on the positioning shaft 42 through a fixing bolt. The end of the support guide rod 43 is fixedly installed with a positioning guide plate 44 on the upper and lower end surfaces, respectively. A rotating cylinder 45 is hinged on the assembly seat 4 above the short rib blanking mechanism, and the piston rod end of the rotating cylinder 45 is connected to the positioning shaft 42 through a connecting rod B46. Since the mesh is welded by steel bars, the mesh end is easy to sag without support when the mesh passes through the welder. The function of the positioning guide plate 44 is to support the end of the mesh through the positioning guide plates 44 arranged up and down during the mesh passes through the welder, so that the mesh is not easy to sag and bend, while maintaining the spacing between the meshes. The function of the rotating cylinder 45 is to drive the connecting rod B46 to move, and then drive the positioning shaft 42 to rotate, thereby driving the supporting guide rod 43 to swing with the positioning shaft 42 as the axis, so that the positioning guide plate 44 can swing between the meshes, and then support the end of the mesh, and at the same time, after the short ribs are welded, the positioning guide plate 44 is moved away from between the meshes to avoid interference with the short ribs welded on the mesh. Since the supporting guide rod 43 is connected to the positioning shaft 42 by a fixing bolt, the position of the supporting guide rod 43 on the positioning shaft 42 can be adjusted after the fixing bolt is loosened, and then the position of the positioning guide plate 44 and the spacing between the positioning guide plates 44 can be adjusted, thereby making the position of the positioning guide plate 44 and the spacing between the positioning guide plates 44 adapt to the mesh.

[0056] The ends of the positioning guide plate 44 are bent respectively, the purpose of which is to form a V-shaped opening between the ends of the upper and lower positioning guide plates 44, thereby guiding the ends of the mesh so that the mesh can enter between the upper and lower positioning guide plates 44.

[0057] A method for welding using a steel mesh cage welding machine comprises the following steps:

[0058] 1) Adjust the short bar feeder, upper welding head and end straightener of the steel mesh cage welding machine according to the length and diameter of the short bar.

[0059] The specific process is:

[0060] A. Loosen the fixing bolts between the root limiting plate 10 and the positioning side plate 14 and between the root limiting plate 10 and the length limiting plate 16, and adjust the distance between the root limiting plate 10 and the bottom bracket 9 on the positioning side plate 14 and between the root limiting plate 10 and the bottom bracket 9 on the length limiting plate 16 according to the diameter of the short ribs. After the adjustment is completed, lock the fixing bolts between the root limiting plate 10 and the positioning side plate 14 and between the root limiting plate 10 and the length limiting plate 16 to fix the positions of the root limiting plate 10 on the positioning side plate 14 and the length limiting plate 16, respectively, and then lock the distance between the root limiting plate 10 and the bottom bracket 9, so that the short ribs can only be cut one by one.

[0061] B. Loosen the positioning bolts between the bottom bracket 9 on one side of the length limit plate 16 and the supporting bottom plate 13 and between the disturbance plate 25 and the disturbance shaft 22, and adjust the distance between the length limit plate 16 and the positioning side plate 14 according to the length of the short ribs. After the adjustment is completed, lock the fixing bolts between the bottom bracket 9 and the supporting bottom plate 13 to lock the distance between the length limit plate 16 and the positioning side plate 14; after the position adjustment of the length limit plate 16 is completed, adjust the position of the disturbance plate 25 so that the disturbance plate 25 does not interfere with the root limit plate 10. After the adjustment is completed, lock the fixing bolts between the disturbance plate 25 and the disturbance shaft 22.

[0062] C. Remove the fixing bolts on the support block 35, move the position of the sliding electrode 36 on the support block 35 according to the length of the short ribs and the spacing between the meshes, and adjust the spacing between the sliding electrode 36 and the lower welding head 5. After the adjustment is completed, pass the fixing bolts through the longitudinal adjustment holes 38 corresponding to the sliding electrode 36 to fix the sliding electrode 36 to the support block 35.

[0063] D. Loosen the fixing bolts between the support guide rod 43 and the positioning shaft 42, and move the positioning guide plate 44 according to the spacing between the meshes and the length of the short ribs. After the adjustment is completed, tighten the fixing bolts between the support guide rod 43 and the positioning shaft 42 to lock the spacing between the positioning guide plates 44 at both ends of the positioning shaft 42.

[0064] 2) Overlap the two mesh sheets and transport them between the welders. When transporting the mesh sheets, start the rotating cylinder 45, swing the positioning guide plate 44 to between the welders to support the ends of the mesh sheets. During the transportation of the mesh sheets, put the short ribs between the top end of the base 9, the root limit plate 10, the positioning side plate 14, and the length limit plate 16. After putting in enough short ribs, start the disturbance cylinder 23 to make the disturbance plate 25 swing repeatedly, thereby disturbing the short ribs and cutting them one by one.

[0065] 3) When the welding points designed on the mesh are transported to the upper welding head and the lower welding head 5, the mesh stops moving forward; after the mesh stops, the rodless cylinder 12 is started, and the rodless cylinder 12 pushes the short ribs on the positioning bottom plate 8 to the longitudinal limit groove 33 of the magnetic flap 29 through the push rod 11.

[0066] 4) Start the flip cylinder 30, which drives the short ribs to change from a horizontal state to a vertical state through the magnetic flap 29, and at the same time drives the short ribs to move toward the electrode conduction plate 28, so that the short ribs are fixed in the longitudinal limit groove 33 of the electrode conduction plate 28 under the magnetic force of the magnetic support plate 27.

[0067] 5) After the short ribs are transferred to the electrode conduction plate 28, the turning cylinder 30 drives the magnetic flap 29 to reset; during the resetting process of the magnetic flap 29, the lifting cylinder 26 is started, and the lifting cylinder 26 drives the short ribs upward to between the meshes through the assembly plate 31, the magnetic support plate 27, and the electrode conduction plate 28 in sequence.

[0068] 6) Start the lower electrode cylinder 6 and the upper electrode cylinder 7 synchronously. The lower electrode cylinder 6 pushes the lower welding head 5 and the upper electrode cylinder 7 pushes the upper welding head toward the mesh respectively. The lower welding head 5 pushes the lower mesh, the bottom end of the short rib, and the electrode conduction plate 28 to collide with each other in sequence. The upper welding head pushes the upper mesh, the top end of the short rib, and the electrode conduction plate 28 to collide with each other in sequence. The electrode conduction plate 28 conducts the upper welding head and the lower welding head 5 through the short rib and the mesh, forming a current between the short rib and the mesh, and welding the short rib and the mesh.

[0069] 7) After the short ribs collide with the mesh, that is, after the short ribs and the mesh are welded, the lower electrode cylinder 6 and the upper electrode cylinder 7 are reset respectively, so that the upper welding head and the lower welding head 5 are separated from the mesh respectively; after the upper welding head and the lower welding head 5 are separated from the mesh respectively, the lifting cylinder 26 drives the electrode conduction plate 28 to reset downward.

[0070] 8) During the resetting process of the lifting cylinder 26, the rotating cylinder 45 drives the positioning guide plate 44 to reset, and the end of the mesh is supported by the welded short ribs, and the support of the positioning guide plate 44 is no longer needed.

[0071] 9) After the lifting cylinder 26 is reset, the mesh is pushed to move, and steps 3) to 7) are cycled to continuously weld the mesh and the short ribs to complete the welding of the mesh and the short ribs.

[0072] The steel mesh cage welding machine can weld the two sides of the stacked mesh respectively through symmetrically arranged welders; because the short bar feeding mechanism can feed short bars of different specifications and the sliding electrode can slide on the upper welding head to adjust the distance between welding points, short bars of different specifications can be welded to the mesh, and at the same time, the distance between the welders can be adjusted by lateral adjustment of the lead screw, so that the welder can adapt to meshes of different widths, so that short bars of different specifications can be welded to the mesh by adjustment without replacing the whole machine, and it has good universality; it solves the problem that the existing welding equipment has poor universality and cannot weld stacked meshes.
