Description

Technical Field

[0001] The invention belongs to the technical field of pipe pile cage reinforcement processing, in particular to a rolling welding device and a process thereof for pipe pile cage reinforcement processing. Background Art

[0002] As a commonly used foundation pile type, pipe piles are widely used in infrastructure construction fields such as buildings, bridges, and ports. In the manufacturing process of pipe piles, cage reinforcement is an important component, which can enhance the structural strength and stability of pipe piles and improve the performance of pipe piles when bearing loads. In order to improve welding efficiency, cage reinforcement will be automatically welded by rolling welding equipment during welding. During welding, multiple groups of steel bars are fixed on the rotating disk in the equipment, and then the steel wire is conveyed to the steel bar through the wire feeder for conveying steel wire. Then, as the rotating disk rotates, the multiple groups of steel bars are driven to rotate, so that under the action of the friction between the surface of the steel bar and the steel bar, the steel wire is forced to bend and fit the surface of the steel bar, and bending deformation occurs. At this time, the steel wire is spirally wound around the multiple groups of steel bars, and then the movement trajectory and pressure of the welding gun (electrode) are accurately controlled by the manipulator, and resistance heat is generated at the contact part between the spiral steel wire and the steel bar, realizing non-contact indirect welding, and completing the welding operation of the contact part between the steel wire and the steel bar.

[0003] In the prior art, as the rotating disk rotates, it drives multiple groups of steel bars to rotate. Under the action of the friction between the steel bar surfaces, the steel wire is forced to bend and fit the steel bar surface, causing bending deformation. When the welding part after welding is not fully cooled in time, the vibration between the steel wire and the steel bar caused by the rotation of the steel bar may cause partial offset. At this time, the welding part between the steel wire and the steel bar that has not been fully cooled may become loose, resulting in an unstable welding part, affecting the firmness of the welding and reducing the welding quality of the steel cage. For this reason, we propose a rolling welding device and process for pipe pile cage reinforcement processing. Summary of the invention

DETAILED DESCRIPTION

[0041] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Embodiment 1

[0043] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 The present invention provides a technical solution: a rolling welding device for processing pipe pile cage reinforcement, comprising a sliding frame 101, a fixed frame 102 and a rotating disk 109 rotatably arranged inside the sliding frame 101 and the fixed frame 102, the sliding frame 101 can move to the left direction to drive the steel bar 103 to move with it, and multiple groups of steel bars 103 are arranged on the rotating disk 109, and the steel bars 103 are driven to rotate by the rotating rotating disk 109 to achieve a rolling welding effect, the outside of the steel bar 103 is wound with a steel wire 108, and a limiting mechanism is arranged on one side of the steel bar 103, and the limiting mechanism includes:

[0044] The clamping assembly includes two groups of rotating columns 207 and multiple groups of pressing wheels 201 rotatably arranged outside the rotating columns 207, and is used to clamp and limit the steel wire 108;

[0045] Two sets of bidirectional screw rods 210 are fixedly sleeved on the outside of the rotating column 207, and two sets of nut seats 213 are arranged on the outside of the bidirectional screw rods 210. When the nut seats 213 move, they will drive the top limit plate 306 to move on the limit rod 212 to limit the nut seats 213. Both ends of the limit rod 212 are fixed on the lower tube 203, and are used to drive the pressure wheel 201 to move and adjust in the left and right directions according to the spacing between the steel wires 108.

[0046] The outer sleeve of the nut seat 213 is provided with a mounting bearing 211, and the mounting bearing 211 facilitates the pressure wheel 201 to rotate when it contacts the rotating steel wire 108. The inner wall of the pressure wheel 201 is fixed to the outer side of the mounting bearing 211, and the bottom of the hollow tube 304 is fixed to the two ends of the nut seat 213, so that the hollow tube 304 can move with the movement of the nut seat 213. A limiting rod 212 is provided inside the nut seat 213, and the nut seat 213 is slidably arranged on the limiting rod 212;

[0047] Two sets of support bearings 209 are sleeved on the outside of the rotating column 207, and the support bearings 209 facilitate the rotation of the rotating column 207. The forward or reverse rotation of the rotating column 207 drives the bidirectional screw rod 210 to rotate, so that the two sets of nut seats 213 move towards or away from each other. The outer wall of the support bearing 209 is fixedly provided with a lower tube 203, and one side of the fixing frame 102 is fixedly provided with an arc plate 200, and the top of the lower tube 203 passes through the inside of the arc plate 200;

[0048] The outer wall of the arc-shaped plate 200 is fixedly provided with a plurality of mounting blocks 205, the interior of the mounting blocks 205 is connected with locking screws 206 through threads, and the working ends of the locking screws 206 extend to the surface of the lower tube 203;

[0049] The limiting mechanism also includes a rotating assembly, which includes two groups of rotating rods 204 rotatably arranged on one side of the inner side of the arc-shaped plate 200, a pulley is sleeved on the top of the rotating rod 204, and a transmission belt 208 is sleeved between the two groups of pulleys for linking the two groups of rotating columns 207 to rotate;

[0050] A first bevel gear is fixedly disposed at the bottom of the rotating rod 204 , and a second bevel gear is fixedly disposed at one end of the rotating column 207 , and the first bevel gear is meshed with the second bevel gear.

[0051] Through the designed limiting mechanism of the present invention, multiple groups of pressure wheels 201 can press the steel wire 108 before and after welding, so that the contact between the steel wire 108 and the steel bar 103 is stable, the probability of deviation is reduced, the welding effect of the welding part is improved, and it is ensured that the steel wire 108 can be stably wound. Moreover, the position of the pressure wheel 201 can be synchronously adjusted with the different spacings between the steel wires 108, thereby increasing the firmness of the welding part and improving the welding quality of the steel cage.

[0052] In summary, during use, the steel wire 108 is spirally wound around the outside of the multiple groups of steel bars 103. At this time, the multiple groups of pressing wheels 201 press and limit the steel wire 108 before and after welding, and then the welding gun 112 is moved by the manipulator 107 to weld the contact position between the steel wire 108 and the steel bar 103. Before welding, the steel wire 108 is pressed by the pressing wheel 201, which can increase the steel wire 108 when it is close to the welding gun 112 for welding, and increase the contact effect between the steel wire 108 and the steel bar 103. After welding, the steel wire 108 is pressed and limited by the pressing wheel 201, which can increase the contact area of ​​the contact welding part between the steel wire 108 and the steel bar 103, thereby increasing the contact time of the contact part between the steel wire 108 and the steel bar 103, increasing the solidification time at the welding part, and thus improving the firmness at the welding position.

[0053] Before welding, the spacing between the two groups of pressure wheels 201 can be adjusted according to the spacing between the spiral steel wires 108, so that the pressure wheels 201 can contact the steel wires 108. The spacings of the steel wires 108 of different groups wound around the outside of the reinforcing bars 103 are different. When adjusting, hold one group of rotating rods 204 and rotate them, and drive the other group of rotating rods 204 to rotate synchronously through the transmission belt 208. Then the rotating rotating rods 204 drive the first bevel gear at the bottom to rotate, and then drive the second bevel gear meshing with it to rotate, and then drive the rotating column 207 to rotate. The rotating column 207 drives the two groups of bidirectional screw rods 210 on the outside to rotate, so that the two groups of nut seats 213 located on the outside of the bidirectional screw rods 210 move in opposite directions, driving the mounting bearings 211 and the external pressure wheels 201 to move accordingly. At this time, the spacing can be adjusted. When the adjustment is completed, stop rotating, so that multiple groups of pressure wheels 201 can contact and press different steel wires 108 with different spacings for use;

[0054] When adjusting the height of the pressing wheel 201 according to the different diameters of the steel wires 108 or the different diameters of the steel bars 103, the locking screw 206 is loosened by turning it outward to make the working end of the locking screw 206 away from the surface of the lower tube 203, and then the two sets of rotating columns 207 are moved upward or downward, thereby driving the pressing wheel 201, the locking screw 206 and other structures to move up and down. After the movement is completed, the locking screw 206 is rotated toward the lower tube 203 and tightened to fix the lower tube 203.

[0055] Embodiment 2

[0056] Based on Example 1, please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 A cooling assembly is provided on the arc plate 200, and the cooling assembly includes a cooling fan 300 fixed on the outer wall of the arc plate 200 and a hollow tube 304 fixed on the outside of the nut seat 213, and a plurality of blowing heads 305 are fixedly provided on the hollow tube 304 for cooling the welding part;

[0057] A telescopic tube 302 is fixedly arranged between the two groups of hollow tubes 304 and between the hollow tube 304 and the lower tube 203. An upper rod 303 is fixedly arranged between the two groups of lower tubes 203. Multiple groups of limit plates 306 are slidably arranged outside the upper rod 303. The bottom of the limit plate 306 is fixedly connected to the hollow tube 304.

[0058] An upper pipeline 202 is fixedly arranged between the tops of the lower tubes 203 , and a telescopic hose 301 is fixedly arranged on the air cooler 300 . The air cooler 300 generates cold air, which is then transported to the upper pipeline 202 through the telescopic hose 301 . The telescopic hose 301 is connected to the upper pipeline 202 , and a solenoid valve is arranged on the lower tube 203 .

[0059] The present invention cooperates with the limiting mechanism through the designed cooling component to cool the welding position and the surrounding area of ​​the welding part during the process of tightening the steel wire 108, thereby accelerating the cooling time of the welding position, reducing the solidification time of the welding position, further improving the welding firmness of the welding position, and reducing the damage of high temperature to the steel wire 108 and the steel bar 103, thereby extending their service life.

[0060] In summary, the air cooler 300 is turned on during the process of the pressing wheel 201 rotating to compress and limit the steel wire 108. The air cooler 300 transmits the generated cold air to the upper pipe 202 through the telescopic hose 301, and then enters the hollow pipe 304 through the lower pipe 203 and the telescopic pipe 302, and then blows the cold air downward through the multiple sets of blowing heads 305. At this time, the cold air is blown to the surface of the pressing wheel 201 below, the steel wire 108 and the steel bar 103. The cold air blown to the surface of the pressing wheel 201 is affected by the curved surface of the outer wall of the pressing wheel 201 and is also blown to the surface of the steel wire 108 and the steel bar 103 below, so as to accelerate the cooling of the welding position. At the same time, the cold air blown to the pressing wheel 201 will also increase the surface temperature of the pressing wheel 201. The high temperature at the welding position of the steel wire 108 can be cooled down when the steel wire 108 contacts with the steel wire 108, and the amount of gas blown into the hollow tube 304 can be adjusted by adjusting the opening size of the electromagnetic valves on different lower tubes 203, so that the blowing head 305 blows out different amounts of gas, thereby making the blowing amounts of the blowing heads 305 on the two groups of rotating columns 207 located in the front and rear of the equipment different, the amount of gas ejected at the front is large, and the amount of gas ejected at the rear is smaller. The large amount of gas can quickly cool the welding position that first contacts with the steel wire 108. At this time, the high temperature at the welding position becomes smaller, and then it is cooled by a smaller amount of gas through the rear blowing head 305, thereby increasing the cooling effect on the welding position.

[0061] Embodiment 3

[0062] Based on Example 2, please refer to Figure 1-Figure 6 A limiting member for limiting the position of the steel wire 108 is arranged on the other side of the arc plate 200, and the limiting member includes a circular plate 400 and a limiting ring 401 fixed on the other side of the arc plate 200. A plurality of groups of balls 403 are arranged for rolling inside the limiting ring 401. The balls 403 can roll on the inner wall of the limiting ring 401 to reduce the wear on the steel wire 108;

[0063] The end of the steel wire 108 passes through the interior of the limiting ring 401 , a stud 402 is fixedly provided on the top of the limiting ring 401 , and the top of the stud 402 passes through the interior of the circular plate 400 , and the exterior of the stud 402 is threadedly connected with two sets of threaded rings.

[0064] The limiting member designed in the present invention can limit the position of the steel wire 108 during the process of conveying the steel wire 108 through the wire feeder 105, so that the steel wire 108 can be wound around the outside of multiple groups of steel bars 103 according to the path, and at the same time, the welding accuracy of the steel wire 108 and the steel bars 103 at the welding position by the welding gun 112 can be improved later, and the multiple groups of balls 403 inside the limiting ring 401 are in rolling contact with the steel wire 108, thereby reducing the friction loss of the steel wire 108 and extending the service life of the steel wire 108.

[0065] In summary, during use, the steel wire 108 will first pass through the inside of the limiting ring 401 to limit the steel wire 108 when it is wound, so that the starting position of the steel wire 108 wound on the steel bar 103 will not be offset or changed, thereby improving the winding effect and facilitating subsequent welding operations. In addition, the multiple groups of balls 403 inside the limiting ring 401 are in rolling contact with the steel wire 108, reducing the contact friction loss of the steel wire 108 and extending the service life of the steel wire 108. At the same time, the position of the limiting ring 401 can be adjusted according to the diameter or position of the steel wire 108. When adjusting, first loosen the two groups of threaded rings located outside the stud 402 by turning them in opposite directions, and then move the stud 402 left and right or up and down in the circular plate 400 to drive the limiting ring 401 below to move with it. After moving, the two groups of threaded rings are turned in opposite directions and tightened to adjust.
