Description

Technical Field

[0001] The invention relates to the technical field of welding, in particular to a steel bar welding device and a method for welding steel bars used in building construction. Background Art

[0002] Rebar welding can form a strong connection between the steel bars, thereby improving the stability and bearing capacity of the overall structure. Welded connections are usually stronger than traditional bolted connections and can withstand greater loads. Rebar welding can be applied to various structural forms, including beams, columns, plates, frames, etc., and has strong versatility and adaptability. Whether it is a simple steel bar connection or a complex structural welding, it can be achieved through welding technology. In general, rebar welding, as an efficient and reliable connection method, plays an important role in construction and structural engineering. It can improve the strength, stability and durability of the structure, and can also reduce engineering costs and construction cycles. It is one of the indispensable important technologies in modern construction engineering. Manual arc welding uses an electric arc to heat the steel bars to a molten state, and then connects the steel bars into components through melting and filling of the electrode. Manual arc welding has the advantages of simple operation and low equipment cost.

[0003] For example, the existing Chinese patent, application number 202021255303.5, is a steel bar welding device for construction, which is used in conjunction with a bottom plate, a connecting threaded column, a rotating ferrule, a threaded sleeve, a support rod, a top plate, a second arc-shaped groove, a fixing mechanism, and a welding protection frame. The steel bar is clamped and fixed by the fixing mechanism, and the threaded sleeve can be raised and lowered on the connecting threaded column by rotating the rotating ferrule. When welding, the threaded sleeve descends, so that the adjacent end of the steel bar descends to the inside of the welding protection frame for welding;

[0004] However, the existing steel cage welding requires operators to have certain skills and experience, and the welding quality is greatly affected by the technical level of the operators. The quality of the steel bar welding used in construction depends entirely on the experience and level of the construction workers, which results in some steel cages being difficult to use after welding and requiring secondary rework and difficult to achieve structural strength, reducing construction efficiency. In order to avoid the above-mentioned technical problems, it is indeed necessary to provide a steel bar welding device and method for construction to overcome the above-mentioned defects in the prior art.

Then the cage is completely removed from the welding equipment and then used for construction.

[0036] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0037] 1. A welding assembly is provided. Several transverse steel bars are sequentially placed into the inner side of the steel bar fixing groove plate, and the positions of the sliding sleeve and the sliding rod are sequentially adjusted to determine the diameter of the cage to be welded. Then, the positions of all the sliding sleeves and the sliding rods are locked and fixed. The annular extrusion rod is moved to the outer side of one of the steel bar fixing groove plates by the moving sliding seat. The operator inserts the steel bar to be welded into the gap between the extrusion groove and the steel bar fixing groove plate, adjusts the contact position between the transverse steel bar and the ring beam steel bar of the welding gun and the opposing welding gun, starts the welding gun and the opposing welding gun for preliminary welding and fixing, and then drives the extrusion motor to drive the welding gun and the opposing welding gun to weld the steel bar. The dynamic annular extrusion rod extrude and bend the ring beam steel bars in the extrusion groove, so that it is constantly bent to fit all the transverse steel bars inside the steel bar fixed groove plate, and whenever the ring beam steel bar contacts a transverse steel bar, the welding gun and the opposite welding gun are started to weld the ring beam steel bar and the transverse steel bar, so that the ring beam steel bar forms a steel bar ring that completely fits the transverse steel bar, without the operator bending and welding the steel bar ring in advance according to his own experience, which not only ensures the size of each part of the entire steel cage but also ensures the overall strength of the entire steel cage, thereby eliminating the need for secondary rework, saving construction time, and thus improving project progress and quality.

[0038] 2. A stretching assembly is provided, and all the steel bars to be welded are inserted into the inner positions of the positive clamping ring plate and the auxiliary clamping ring plate in turn. Then the operator tightens all the clamping threaded rods on the top of the positive clamping ring plate and the auxiliary clamping ring plate in turn, and controls the stretching hydraulic push rods on both sides to extend outward. At this time, the steel bars are stretched, and the rust attached to their surface will initially fall off. The transverse groove plate is controlled to slide on the outer top of the transverse sliding rod, thereby driving the water tank to slide, and then the pressurized water pump inside the water pump seat on the top of the water tank is turned on to spray the rust remover inside the water tank. At this time, the rust remover can be evenly sprayed onto the outer surface of the steel bar through the nozzle, thereby removing the rust spots formed on the surface of the steel bar for a long time, preventing these rust spots from continuing to corrode and expand, ensuring the use strength of the steel bar, and then improving the overall strength of the steel bar cage to ensure the overall quality of the construction project.

[0039] In summary, the steel bars are stretched by the positive clamping ring plate and the auxiliary clamping ring plate, so that the steel bars are straightened and the size of the entire welded steel cage is more accurate. The ring beam steel bars in the extrusion groove are squeezed and bent by the extrusion motor to continuously fit all the transverse steel bars inside the steel bar fixing groove plate and bend. Whenever the ring beam steel bar contacts a transverse steel bar, the welding gun and the opposite welding gun are started to weld the ring beam steel bar and the transverse steel bar, so that the ring beam steel bar forms a steel bar ring that completely fits the transverse steel bar, so that the size of the entire steel cage can be more accurate. There is no need to bend the ring beam in advance, because each steel bar has been stretched straight, so it is only necessary to fit the ring beam steel bar to the surface of the transverse steel bar, to ensure that the large parts of the entire steel cage are of equal diameter and closely fit with the ring beam steel bar, to prevent the design from not meeting the standards due to manual operation, and to further ensure and improve the strength of the project.

[0070] S3, bending and welding: insert the steel bar into the extrusion groove 239 and the steel bar fixing groove plate 213, drive the annular extrusion rod 238 to extrude and bend the ring beam steel bar in the extrusion groove 239 through the extrusion motor 235, and perform welding whenever the ring beam steel bar contacts a horizontal steel bar;

[0071] S4, adjusting the position: turning off the positioning electromagnet 212, driving the rotating ring plate 203 to rotate inside the fixed ring plate 201 through the servo motor 205, and rotating the unwelded part of the ring beam reinforcement to the inner side of the extrusion groove 239;

[0072] S5: Remove the finished product: Pull the entire steel cage as a whole on the outside of the steel fixing groove plate 213, and the other end of the steel cage will be on the other side of the support plate 224. The support plate 224 is reinserted into the interior of the stabilizing seat 226, and then the cage is completely removed from the welding equipment and then used for construction.

[0073] The working principle and use process of the present invention are as follows: first, before the operator needs to weld a batch of steel cages, the operator first determines the diameter of the steel cages to be welded, and then the operator loosens all the positioning screws 219 in turn, thereby sliding the sliding rod 216 on the inner side of the positioning plate 217, and controls the corresponding hydraulic push rod 210 to extend and retract while sliding the sliding rod 216. At this time, the hydraulic push rod 210 will push the push plate 211 to move outward, thereby driving the sliding sleeve 209 to slide on the outer side of the connecting rod 207 through the push plate 211, and because the sliding sleeve 209 and the sliding rod 216 slide outward at the same time, the sliding rod 216 and the sliding sleeve 209 will simultaneously drive the steel bar fixing groove plate 213 to slide outward, and after the sliding rod 216 and the sliding sleeve 209 move to the specified diameter position of the welded steel cage, the positioning screw 219 is tightened to fix the sliding rod 216, and the diameter of the steel cage is determined after all the sliding rods 216 are operated in the same way in turn;

[0074] Next, the operator places the straightened steel bar into the groove built into the steel bar fixing slot plate 213. At this time, the steel bar will be adsorbed by the fixing magnet 215 and fixed to the inner side of the steel bar fixing slot plate 213 at the top position of the rubber pad 214. The operator controls all the slide rails 232 to move to the required spacing position of the steel bar ring from the inner side of the slot plate 231, and controls the sliding seat 233 to slide on the top of the slide rail 232 to move the annular extrusion rod 238 to the outer side of one of the steel bar fixing slot plates 213, and reserve a space for a steel bar between the steel bar fixing slot plate 213 and the extrusion groove 239. Then, the operator inserts the steel bar to be welded into the gap between the extrusion groove 239 and the steel bar fixing slot plate 213. At this time, the sliding seat 233 is controlled to move slightly toward the steel bar fixing slot plate 213, so as to clamp the steel bar to be welded.

[0075] Next, the operator controls the two angle adjustment hydraulic rods 244 to retract at the same time, thereby lowering the angle of the angle adjustment rod 242, and then controls the length hydraulic rod 245 to retract, and then fits the welding gun 243 and the opposite welding gun 246 to the contact position between the transverse steel bars inside the steel bar fixing slot plate 213 and the ring beam steel bars inside the extrusion slot 239, starts the welding gun 243 and the opposite welding gun 246 to preliminarily weld and fix the ring beam steel bars and the transverse steel bars, and then controls the extrusion motor 235 to rotate, and then drives the extrusion gear 236 to rotate through the extrusion motor 235, thereby driving the annular extrusion rod 238 to slide on the inner side of the directional slot plate 237. At this time, as the annular extrusion rod 238 continues to slide upward, it will squeeze the ring beam steel bars in the bending extrusion slot 239, so that it will continuously fit all the transverse steel bars inside the steel bar fixing slot plate 213 and be bent, and whenever the ring beam steel bar contacts a transverse steel bar, the welding gun 243 and the opposite welding gun are started The gun 246 welds the ring beam steel bars and the transverse steel bars, and when the annular extrusion rod 238 rotates to the maximum angle, the extrusion motor 235 is controlled to rotate in the opposite direction to rotate the annular extrusion rod 238 back to the initial position, and the positioning electromagnet 212 is turned off at the same time, and then the servo motor 205 is started. By controlling the servo motor 205, the servo motor 205 drives the driving wheel 206 to rotate, thereby driving the rotating ring plate 203 to rotate inside the fixed ring plate 201, so as to drive all the steel bar fixing groove plates 213 to rotate, and the unwelded part of the ring beam steel bar can be rotated to the inner side of the extrusion groove 239, and then the servo motor 205 is turned off to stop rotating, and the positioning electromagnet 212 is turned on at the same time to adsorb and fix the rotating ring plate 203, and then the extrusion motor 235 can be started again to drive the annular extrusion rod 238 to bend and fit the ring beam steel bar, and the welding gun 243 and the opposite welding gun 246 are used to weld and fix the steel bar;

[0076] Then, when the welding of the steel cage is completed, the length limiting rod 227 is pulled according to the overall length of the cage to slide it to the maximum position to ensure that the limiting sleeve 222 and the length limiting rod 227 are at the maximum length position. At this time, the folding plate 229 is rotated to the vertical position, and the folding plate 229 is inserted into the inner side of the base 230 to fix the limiting sleeve 222 and the length limiting rod 227. At this time, the folding support plate 224 is adsorbed at the bottom position of the limiting sleeve 222 through the folding magnet 225. The entire steel cage is then pulled as a whole outside the steel bar fixing groove plate 213 to the side close to the rear support groove plate 228. At this time, the other end of the steel cage will be on the other side of the support plate 224. The operator then reinserts the support plate 224 into the interior of the stabilizing seat 226 to support the limiting sleeve 222. The operator then adsorbs the folding plate 229 to the bottom of the limiting sleeve 222, and then completely removes the cage from the welding equipment for construction use.

[0077] By placing a number of transverse steel bars into the inner side of the steel bar fixing groove plate 213 in sequence, and adjusting the positions of the sliding sleeve 209 and the sliding rod 216 in sequence, the diameter of the cage to be welded is determined, and then the positions of all the sliding sleeves 209 and the sliding rods 216 are locked and fixed, and the sliding seat 233 is moved to move the annular extrusion rod 238 to the outside of one of the steel bar fixing groove plates 213, and the operator inserts the steel bar to be welded into the gap between the extrusion groove 239 and the steel bar fixing groove plate 213, and adjusts the contact position between the transverse steel bar and the ring beam steel bar of the welding gun 243 and the opposite welding gun 246, and starts the welding gun 243 and the opposite welding gun 246 for preliminary welding and fixing, and then The ring beam reinforcement in the bending and extrusion groove 239 is driven by the extrusion motor 235 to be extruded and bent by the annular extrusion rod 238, so that the ring beam reinforcement is continuously bent to fit all the transverse reinforcements in the reinforcement fixing groove plate 213, and whenever the ring beam reinforcement contacts a transverse reinforcement, the welding gun 243 and the opposite welding gun 246 are started to weld the ring beam reinforcement and the transverse reinforcement, so that the ring beam reinforcement forms a reinforcement ring that completely fits the transverse reinforcement, without the need for the operator to bend and weld the reinforcement ring in advance according to his own experience, which not only ensures the size of each part of the entire reinforcement cage but also ensures the overall strength of the entire reinforcement cage, thereby eliminating the need for secondary rework, saving construction time, and thus improving the progress and quality of the project;

[0078] Finally, before welding the steel bars, the sealing cover 313 on the top of the filling port 312 is loosened to fill the rust remover into the inner side of the water tank 311. The operator inserts all the steel bars to be welded into the inner side of the positive clamping ring plate 303 and the auxiliary clamping ring plate 317 in turn. Then the operator tightens all the clamping threaded rods 305 on the top of the positive clamping ring plate 303 and the auxiliary clamping ring plate 317 in turn, thereby pushing the clamping plates 308 on both sides to move downward at the same time to fit the top positions of all the steel bars. At this time, all the steel bars are fixed. After all the steel bars are fixed, the stretching hydraulic push rods 302 on both sides are controlled to move The clamping plate 308 is stretched outward, thereby continuously pushing the positive clamping ring plate 303 and the auxiliary clamping ring plate 317 on both sides, thereby stretching the steel bar, and the rust attached to the surface of the steel bar will initially fall off. Then, after the steel bar is straightened, all the steel bars are in a straight state, which is convenient for people to quickly weld. Then, all the clamping threaded rods 305 are loosened to release the position restriction of the clamping plate 308. Then, under the action of the reset spring 307, the reset spring 307 will bounce the clamping slide bar 306 upward, and then reset the clamping plate 308 to the initial position, so as to facilitate the operator to place and fix the next batch of steel bars;

[0079] Then, the transverse groove plate 310 is controlled to slide on the outer top of the transverse slide bar 309, thereby driving the water tank 311 to slide, and then the pressurized water pump 315 inside the water pump seat 314 on the top of the water tank 311 is turned on to spray out the rust remover inside the water tank 311. At this time, the rust remover can be evenly sprayed onto the outer surface of the steel bar through the nozzle 316, so as to remove the rust spots formed on the surface of the steel bar for a long time, prevent these rust spots from continuing to corrode and expand, ensure the use strength of the steel bar, and then improve the overall strength of the steel bar cage to ensure the overall quality of the construction project, and stretch the steel bar through the positive clamping ring plate 303 and the auxiliary clamping ring plate 317, so as to straighten the steel bar so that the size of the entire welded steel bar cage is more accurate, and then the ring beam steel bar is completely welded to the surface of the horizontal steel bar cage through the annular extrusion rod 238, so that the size of the entire steel bar cage can be more accurate, prevent the design from not meeting the standards due to manual operation, and further ensure and improve the engineering strength;

[0080] By stretching the steel bars by the positive clamping ring plate 303 and the auxiliary clamping ring plate 317, the steel bars are straightened so that the size of the entire welded steel cage is more accurate. The ring beam steel bars in the bending extrusion groove 239 are squeezed by the extrusion motor 235 to make them continuously fit all the transverse steel bars inside the steel bar fixing groove plate 213 and bend. Whenever the ring beam steel bars touch a transverse steel bar, the welding gun 243 and the opposite welding gun 246 are started to weld the ring beam steel bars and the transverse steel bars, so that the ring beam steel bars form a steel bar ring that completely fits the transverse steel bars, so that the size of the entire steel cage can be more accurate. There is no need to bend the ring beam in advance, because each steel bar has been stretched straight, so it is only necessary to fit the ring beam steel bars on the surface of the transverse steel bars, to ensure that the large parts of the entire steel cage are of equal diameter and fit closely with the ring beam steel bars, to prevent the design from not meeting the standards due to manual operation, and to further ensure and improve the engineering strength.
