Description

Technical Field

[0001] The present application relates to the technical field of steel bar welding, and in particular to a steel bar top-feeding welding device. Background Art

[0002] Steel mesh is a mesh structure made of longitudinal and transverse steel bars arranged at a certain interval and at right angles to each other, with all intersections tied or welded. It is widely used in the construction industry, including beams, columns, floors, roofs, walls, concrete pavements, bridge decks, airport runways, tunnel linings, box culverts, dock floors, prefabricated components and other fields of industrial and civil buildings.

[0003] Among them, steel mesh plays an important role in high-speed rail construction. High-speed rail lines require extremely high stability and safety. Steel mesh is used to reinforce the track foundation, which can enhance the bearing capacity of the foundation, prevent foundation settlement, and ensure the stability of the track and the safety of train operation.

[0004] In order to make the steel mesh fit with the piles on the high-speed railway foundation, a square hole is usually set in the center of the steel mesh. In the related technology, after the entire steel mesh is welded, a cutting machine is usually used to cut the steel mesh to produce a square hole in the center. The above method not only wastes the welding resources used in welding the holes, but also the cut steel mesh is difficult to directly reuse. Summary of the invention

[0043] Reference Figure 1 and Figure 3 In order to limit the positions of the plurality of vertical steel bars on the processing table 1, a plurality of groups of limit frames 4 are installed on one side of the processing table 1 close to the conveying assembly 3. Each group of limit frames 4 is arranged opposite to the vertical steel bars. Each group of limit frames 4 includes two limit frames 4, and the two limit frames 4 are respectively arranged in a ring shape and a frame shape.

[0044] The limiting frame 4 is provided with a positioning assembly 5 for fixing the steel bar in the limiting frame 4.

[0047] Reference Figure 1 , Figure 5 and Figure 6 The upper end of the processing table 1 is provided with a short transverse steel bar feeding mechanism 6 for adding short transverse steel bars to the processing table 1. The short transverse steel bar feeding mechanism 6 is arranged in two groups, and the straight-line distance between the two groups of short transverse steel bar feeding mechanisms 6 is the length of the reserved hole.

[0048] The short transverse steel bar feeding mechanism 6 includes a storage platform 61 installed on the processing table 1. The storage platform 61 in this embodiment is a front-to-back movable platform, which is moved back and forth by a cylinder. The storage platform 61 is used to store short transverse steel bars.

The bottom end of the second cylinder 654 is hinged on the support frame 651, and the telescopic end of the second cylinder 654 is hinged on the arc-shaped side wall of the first cylinder 652.

[0050] Furthermore, the first cylinder 652 can be controlled to extend so that the magnet block 653 on the first cylinder 652 can adsorb the short transverse steel bars. The first cylinder 652 can then contract again. The second cylinder 654 can then be controlled to change the direction of the first cylinder 652 so that the magnet block 653 on the first cylinder 652 is placed above the baffle 62. The first cylinder 652 can then be controlled to extend rapidly so that the short transverse steel bars can separate from the magnet block 653 under the action of inertia and enter the limiting frame 63 under the obstruction of the baffle 62.

[0051] A control assembly 64 for controlling the falling of short transverse steel bars is provided at the bottom of the limit frame 63. The control assembly 64 includes a control shaft 641, which is rotatably connected to the lower part of the limit frame 63 and is placed at the outlet of the lower end of the limit frame 63. A plurality of feed rings 642 are fixedly connected to the control shaft 641, and the plurality of feed rings 642 are equidistantly arranged along the length direction of the control shaft 641, and the feed rings 642 are coaxially arranged with the control shaft 641.

An adsorption magnet 25 for adsorbing long transverse steel bars or short transverse steel bars is provided on one side of the second electrode block 24.

[0057] When falling horizontally on the vertical steel bars, the adsorption magnet 25 adsorbs the transverse steel bars between the first electrode block 23 and the second electrode block 24. At the same time, in order to improve the stability of the transverse steel bars on the first electrode block 23 and the second electrode block 24, a groove for limiting the position of the transverse steel bars is opened on the side where the first electrode block 23 and the second electrode block 24 are close to each other.

[0065] The implementation principle of the embodiment of the present application is: multiple vertical steel bars in the same steel mesh can be neatly arranged on the preliminary discharge table 12, and at the same time, the length of the vertical steel bars where holes need to be reserved is made shorter than that of other vertical steel bars, and the shorter length is the length of the holes that need to be reserved.

[0066] Then, by controlling the conveying assembly 3, the fixed cylinder 341 in the conveying assembly 3 conveys the plurality of vertical steel bars to the processing table 1. Then, the plurality of vertical steel bars are restricted on the processing table 1 by the limiting frame 4, and the steel bars are fixed in the limiting frame 4 by the positioning assembly 5.

[0067] Then, by starting the long steel bar feeding assembly 11, the long steel bars are dropped onto the multiple vertical steel bars, so that the transverse steel bars and the vertical steel bars are perpendicular, and at the same time, under the action of the adsorption magnet 25, the long transverse steel bars are made to reach the welding position of the welding assembly 2. Then, the connection between the long transverse steel bars and the vertical steel bars is welded by the welding assembly 2, and then, by controlling the moving assembly 10, the steel mesh after welding is moved a distance away from the processing table 1. Then, the vertical steel bars where the through holes need to be reserved are cut by the cutting assembly 8, and then the cutting knife 82 after cutting is fixed and blocks the vertical steel bars, and then the steel mesh is continued to be moved to the side away from the processing table 1 by the moving assembly 10, and at this time, the short transverse steel bar feeding mechanism 6 is started. During the movement, short transverse steel bars are added to both sides of the through holes to be reserved through the short transverse steel bar feeding mechanism 6, and the short transverse steel bars are welded to the vertical steel bars through the welding assembly 2, and then the cutting assembly 8 is controlled to cancel the blocking of the vertical steel bars at the through holes to be reserved, and the multiple vertical steel bars at the reserved through holes are pushed to the side of the collecting platform 9 through the pushing assembly 7, and then the long transverse steel bars are dropped on the multiple vertical steel bars and welded through the long steel bar feeding assembly 11. Then, through holes are generated at the vertical steel bars cut off by the cutting assembly 8, and then the entire steel mesh with through holes is moved to the collecting platform 9 through the moving assembly 10.

The same components are represented by the same figure marks.
