Problems solved by technology

[0003] At present, the steel ladders used for bolt-mesh spray support in soft rock roadways are very large, and most of them use manual welding, which has low efficiency, poor quality stability and high cost.
The automatic welding process technology of steel bar ladder is immature, and no mature and efficient equipment specially used for steel bar ladder welding has been developed on the market. However, with the increase in the use of steel bar ladders, this inefficient manual welding process is becoming more and more unsuitable. The requirements of enterprise development, while the welding rod ladder welding equipment is in the technical state of manual operation and welding rod welding, which requires a lot of manpower, unstable welding quality, high production cost and low production efficiency

Embodiment 1

[0052] A common steel bar ladder includes two long bars parallel to each other and a plurality of short bars arranged between the two long bars and respectively connected to the two long bars. This embodiment provides a mine-used steel bar ladder automated production lines, such as figure 1 , figure 2 with image 3 As shown, it includes straightening area 1, reinforcement area 2, welding area 3 and finished product area 4 which are arranged in sequence according to the production process, and the material transportation between each area is carried out through the conveying line 5;

[0053] The straightening area includes a drawing and straightening machine 11, and the drawing and straightening machine 11 straightens the long tendons 61 and transports them to the tendon cloth area 2 through the conveying line 5. Preferably, the straightening The straightening area is equipped with double rows of drawing and straightening machines 11, which effectively improves the straighte...

Embodiment 2

[0077] The steel bar ladder automatic production line of the present embodiment is basically the same as the first embodiment, the difference is that, as Figure 5 As shown, the welding electrodes 313 are two welding copper rods arranged in parallel, the welding ends of the welding copper rods are provided with cut corners 317, and the slopes of the cut corners 317 can be pressed against the corresponding long ribs 61 When welding, the welding robot arm 312 drives the welding copper bar to move in the direction where the long rib 61 is located, the slope of the cut corner 317 is in contact with the outer surface of the long rib 61, and the The cut corner 317 can exert inward pressure on the long rib 61 along with the movement of the welding copper rod. That is, the welding copper rod moves toward the direction where the long rib 61 is located, and the welding copper rod cooperates with the welding pressure-bearing copper block 315 to heat the welding point between the long rib...

Embodiment 3

[0080] The steel bar ladder automatic production line of this embodiment is basically the same as that of Embodiment 1, the difference is that a welding inspection area (not shown) is provided between the welding area 3 and the finished product area 4, and the welding inspection area includes a welding inspection area. device and a repair welding device, the welding detection device includes a weld detector, the weld detector is connected to the repair welding device and can transmit signals to the repair welding device, and the weld seam welding device The structure is the same as that of the welding device 31 in the welding area 3 , the repair welding device receives the signal transmitted by the weld detector and performs repair welding on the welding defect. The increase of the welding detection area effectively reduces the scrap rate of products, improves the quality of products, makes the production stability of the production line good, and the overall production efficie...

Abstract

The invention discloses an automatic production line of a rebar ladder. The automatic production line comprises a straightening area, a rebar distributing area, a welding area and a finished product area which are sequentially arranged according to a production process, and materials are transported among the areas through a conveying line. The straightening area straightens long rebars through adrawing straightening machine and transports the long rebars to the rebar distributing area through the conveying line. The rebar distributing area comprises a long rebar distributing area for placingthe multiple long rebars in parallel in the transporting direction of the conveying line and a short rebar distributing area for placing multiple short rebars at intervals in the length direction ofthe long rebars. The welding area comprises a welding device for welding the long rebars and the short rebars conveyed from the rebar distributing areas to form the rebar ladder. The finished productarea comprises a turnover unloading mechanism for unloading the rebar ladder conveyed from the welding area and a finished product bin for storing the rebar ladder unloaded by the turnover unloading mechanism. The automatic production line of the rebar ladder is high in automation degree and good in stability, production efficiency and production capacity are effectively improved, the product quality is stable, and the finished product rate of products is increased.

Description

technical field [0001] The invention relates to the field of mechanical automation, in particular to an automatic production line for steel bar ladders. Background technique [0002] Soft rock roadway engineering is a main part of soft rock engineering. Many coal mine roadways in my country are arranged in soft surrounding rocks, and soft surrounding rocks have the characteristics of low strength, severe expansion and rheological properties, which affect the safety of mine production and economy. Benefits, with the development of the coal industry and the increasing depth of mining, there are currently many mines in the country that have serious technical problems in soft rock roadway support. [0003] At present, the steel ladders used for bolt-mesh-sprayed support in soft rock roadways are very large, and most of them use manual welding, which has low efficiency, poor quality stability, and high cost. The automatic welding process technology of steel bar ladder is immature...
