Description

Technical Field

[0001] The utility model relates to the technical field of steel bar welded meshes, and more specifically, to a processing device for reverse-buckled steel bar welded meshes. Background Art

[0002] A steel bar welded mesh is a mesh sheet in which longitudinal steel bars and transverse steel bars are arranged at a certain interval and are perpendicular to each other, and all intersection points are welded together by resistance spot welding. The processing of steel bar welded meshes is completed by special equipment. The longitudinal steel bars are arranged according to the interval requirements and make step-by-step movements, and the transverse steel bars fall into the corresponding positions through a feeding system and are pressed down for resistance welding. Generally, the production of one mesh sheet is completed at a time. After the subsequent mesh sheets are produced, they are stacked and packed. However, such a packing method has a relatively small unit volume weight. Due to the limitation of the loading height in subsequent transportation, it cannot be fully loaded for transportation, resulting in too high transportation costs. For this reason, the method of turning the mesh is adopted: one positive and one negative, buckling two by two to reduce the packing height. The mesh turning can be done manually or by special equipment, but both will increase the corresponding processing costs and reduce the production efficiency. Previously, a processing method and device for interlocked steel bar welded meshes have been proposed. This method can produce two mesh sheets simultaneously and directly process the mesh sheets that are buckled two by two to avoid the subsequent mesh turning operation. At the same time, the production of two mesh sheets is completed at one time, and the production efficiency can also be greatly improved. However, the feeding of the longitudinal steel bars in this method is not on the same plane, which will affect the threading efficiency of the longitudinal steel bars in terms of structure. At the same time, limited by the layout of the longitudinal and transverse steel bars, the transverse steel bars of the two mesh sheets can only enter from the side, which limits the structure of the device.

[0022] The following further describes the utility model in conjunction with the drawings and embodiments:

[0023] Embodiment 1

[0024] From Figures 1 - 3 It can be seen that a processing device for an anti-buckled steel bar welded mesh in this embodiment includes a stepping device 8. The surface of the stepping device 8 is provided with longitudinal steel bar threading holes 801. A plurality of groups of longitudinal steel bar threading holes 801 are spaced apart on the surface of the stepping device 8. The plurality of groups of longitudinal steel bar threading holes 801 are arranged on the same horizontal line. The stepping movement of the stepping device 8 can be realized by a servo motor driving a gear rack. The stepping device 8 can simultaneously penetrate the longitudinal steel bars 7 of two mesh sheets. The longitudinal steel bars 7 are arranged in the longitudinal steel bar threading holes 801. The stepping device 8 drives the longitudinal steel bars 7 to displace horizontally forward. A first electrode device 4 and a second electrode device 5 are spaced apart on the running track of the longitudinal steel bars 7;

[0025] A steel bar feeding device 9 is arranged on the side of the running track of the longitudinal steel bar 7. The steel bar feeding device 9 conveys the lower horizontal steel bar 201 to the lower end of the longitudinal steel bar 7. After the coiled steel bar is straightened, sized and cut into the lower horizontal steel bar 201 by the steel bar feeding device 9, it falls into the welding position at the lower end of the longitudinal steel bar 7.

[0026] A transverse bar blanking bin 6 is arranged at the upper end of the running track of the longitudinal steel bar 7. The transverse bar blanking bin 6 is arranged at intervals on the right side of the first electrode device 4. The upper horizontal steel bar 202 is arranged in the transverse bar blanking bin 6. The transverse bar blanking bin 6 conveys the upper horizontal steel bar 202 to the upper end of the longitudinal steel bar 7. The sized upper horizontal steel bar 202 can fall into the welding position at the upper end of the longitudinal steel bar 7 through the transverse bar blanking bin 6.

[0027] Multiple groups of the first electrode device 4 and the second electrode device 5 are arranged at intervals respectively. Multiple groups of the first electrode device 4 are arranged at equal intervals, and multiple groups of the second electrode device 5 are arranged at equal intervals.

[0028] The first electrode device 4 and the second electrode device 5 are arranged alternately along the running track of the longitudinal steel bar 7.

[0029] Each group of the first electrode device 4 and the second electrode device 5 includes an upper electrode and a lower electrode. Each group of the upper electrode and the lower electrode are correspondingly arranged on the same vertical line. Each group of the upper electrode, the lower electrode and the power supply system form a circuit. The lower electrode is relatively fixed, and the upper electrode can move up and down. The up and down movement of the upper electrode can be realized by a hydraulic cylinder or a pneumatic cylinder. After the longitudinal and transverse steel bars are in place, when the upper electrode presses down, the intersection of the longitudinal and transverse steel bars is conducted, and the resistance heat generated at the intersection melts the metal into a solder joint to connect the longitudinal and transverse steel bars.

[0030] After welding is completed, the stepping device 8 can drive the longitudinal steel bar 7 to move forward by a grid spacing for the next welding. When welding reaches a certain position, the longitudinal steel bar 7 exits the stepping device 8.

[0031] A drag net device 1 is arranged at the front end of the running track of the longitudinal steel bar 7. A drag net hook 3 is arranged on one side of the drag net device 1. The hook head end of the drag net hook 3 is in an F shape. The drag net hooks 3 jointly pull the lower horizontal steel bar 201 and the upper horizontal steel bar 202 and drag out the two welded steel bar meshes that have been welded respectively.

[0032] A processing method of a processing device for a reverse-buckled welded steel bar mesh, the steps of which are as follows:

[0033] Step 1: The longitudinal steel bars 7 of the two mesh sheets are sized straight bars, and are simultaneously inserted into the longitudinal steel bar threading holes 801 on the same plane of the stepping device 8, and are fed into the initial position through the longitudinal movement of the stepping device 8, as Figure 1 shown;

[0034] Step 2: The initial raw material of the lower horizontal steel bars 201 is wire rods. They are fed from one side of the longitudinal steel bars 7 through the steel bar feeding device 9 and cut when reaching the set length. At the same time, the upper horizontal steel bars 202 in the cross-bar blanking bin 6 fall into the welding position at the upper end of the longitudinal steel bars 7 through the blanking device. The first electrode device 4 and the second electrode device 5 perform welding corresponding to the upper welding position of the longitudinal steel bars 7 and the lower welding position of the longitudinal steel bars 7 respectively, and the welding of two mesh sheets can be carried out synchronously;

[0035] Step 3: There are multiple groups of the first electrode device 4 and the second electrode device 5. Each group of the first electrode device 4 and the second electrode device 5 includes an upper electrode and a lower electrode. After the longitudinal steel bars 7, the lower horizontal steel bars 201, and the upper horizontal steel bars 202 are in place respectively, the upper electrode presses down and conducts with the lower electrode for resistance welding;

[0036] Step 4: After welding is completed, the stepping device 7 drives the longitudinal steel bars 7 and the welded lower horizontal steel bars 201 and upper horizontal steel bars 202 to step forward simultaneously by a distance of one grid spacing, as Figure 2 shown;

[0037] Step 5: Repeat the above steps until the welding of two whole mesh sheets is completed;

[0038] Step 6: The drag net hooks 3 on the drag net device 1 drag out the two welded mesh sheets to complete the production of the two mesh sheets (corresponding to the solid-line part steel bar welded mesh and the shaded part steel bar welded mesh in Figure 3 respectively). At this time, the two mesh sheets are buckled in the opposite direction and cooperate with the mesh sheets produced before and after them, realizing the reduction of the packing height; Since two mesh sheets can be produced simultaneously at one time, the production efficiency has also been greatly improved;

[0039] The present utility model adopts a processing device for an anti-buckled steel bar welded mesh. This device also produces two mesh sheets simultaneously and can directly process mesh sheets that are buckled pairwise, avoiding the later operation of turning over the mesh. However, compared with the processing method of the interlocked steel bar welded mesh in the prior art, the feeding of the longitudinal steel bars 7 of the two mesh sheets is on the same plane, and the threading efficiency of the longitudinal steel bars 7 is high, which is beneficial to production. In terms of the feeding of the horizontal steel bars, the horizontal steel bars of one mesh sheet need to be fed from the side, while the horizontal steel bars of the other mesh sheet can be fed from the upper part of the front or from the side. The two mesh sheets produced by this device are buckled in the opposite direction and cooperate with the mesh sheets produced before and after them, realizing the reduction of the packing height, and the production efficiency and packing efficiency have both been greatly improved.

[0040] The above has schematically described the present utility model and its implementation manners. This description is not restrictive, and what is shown in the drawings is only one of the implementation manners of the present utility model. The actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present utility model, design similar structural modes and embodiments to this technical solution without creative efforts, they shall all fall within the protection scope of the present utility model.
