Description

Technical Field

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

[0002] Construction steel bars refer to various steel bars, steel wires, etc. used in reinforced concrete. Steel bars are divided into non-alloy steel bars, low-alloy steel bars, and alloy steel bars according to the type of steel; steel bars are divided into hot-rolled steel bars, heat-treated steel bars, residual heat-treated steel bars, cold-rolled steel bars, cold-drawn steel bars, etc. according to the production process. Steel bars are divided into round steel bars and deformed steel bars according to their appearance. Deformed steel bars are crescent-ribbed steel bars (spiral, herringbone, with longitudinal ribs, without longitudinal ribs); the mechanical properties of steel bars are expressed in strength grades in their grades, in units of MPa. At present, when welding construction steel bars, it is necessary to place two steel bars on the steel bar welding equipment and fix them, and then use a welding gun to weld the butt joints of the two steel bars.

[0003] The Chinese invention (publication number: CN114571172B) patent document discloses a construction steel bar welding auxiliary docking device. The purpose of the present invention is to provide a construction steel bar welding auxiliary docking device that can automatically move two steel bars inward for docking and has a good clamping effect. The technical solution is: a construction steel bar welding auxiliary docking device, including a frame, a support plate, a guide rail, a clamping assembly, etc., a frame is arranged on the top of the support plate, and guide rails are connected to the front and rear sides of the top of the frame, and a clamping assembly for clamping the steel bar is arranged between the frame and the guide rail. By clamping the steel bar between the second connecting rod and the first arc plate, and then stepping on the pedal, the first pull wire, the first connecting sleeve and the second pull wire are pulled, and then the first arc plate and the second arc plate are closed, so that the steel bar can be clamped and the stability of the steel bar is improved.

[0004] However, in the above patent, when welding the steel bars, flying debris will be generated, and the generally separately provided protective mechanism is inconvenient to use. Moreover, after welding the steel bars, the workers will be stabbed by the burrs on the steel bars when taking them, which increases the danger.

[0023] The present invention also provides a method for using a construction steel bar welding device, comprising the following steps:

[0024] S1: First, two steel bars are placed in two fixing tubes respectively, and two fixing screws are screwed to push two fixing plates downward to fix the two steel bars. The control console is used to start the adjusting motor, so that the output shaft of the adjusting motor drives the adjusting screw to rotate, and the adjusting screw drives the two adjusting sleeves to approach each other. The two adjusting sleeves drive the two L-shaped plates to approach each other through the two adjusting plates, and the two steel bars are brought close to each other and butted against each other.

[0025] S2: The control console drives the electric push rod to drive the moving plate to move, and the moving plate drives the hanging plate to move, and the welding gun in the protective cover is located above the joint of the two steel bars. Then the control console drives one of the cylinders to push the protective cover downward. The two steel bars are located in the two arched notches on the protective cover. The welding gun is used to weld the welding points of the two steel bars. At the same time, the rotating motor is started. The output shaft of the rotating motor drives the rotating rod to rotate, and the rotating rod drives the small gear to rotate. The small gear drives the fixed cylinder to rotate by meshing with the gear ring. The fixed cylinder is fixed with multiple limit blocks to make the steel bars in the fixed cylinder rotate stably. At the same time, it cooperates with the welding gun to achieve 360-degree welding of the steel bars. The staff can use the observation window to observe the welding situation;

[0026] S3: The semiconductor refrigeration sheet can cool the water in the cold water tank. The water pump draws the water out of the cold water tank through the water pumping pipe and transports it to the nozzle through the water inlet pipe to cool the welding part, thereby achieving the effect of rapid cooling of the steel bar welding part.

The grinding rod drives the grinding wheel to rotate to grind and polish the steel bar welding place, thereby avoiding the situation where the staff is pierced by burrs when taking it. At the same time, the driving rod drives the worm wheel to rotate through the worm, and the worm wheel drives the transmission rod to rotate, and the transmission rod drives the cam to rotate, and reciprocates to squeeze the convex edge plate to move downward, and compress the reset spring. When the protruding end of the cam is away from the convex edge plate, the reset spring releases the elastic force and moves and resets through the convex edge plate. The convex edge plate drives the knocking rod to move back and forth, so that the knocking rod uses the rubber head to knock on the steel bar welding place, thereby achieving the effect of welding strength detection.

[0028] Compared with the prior art, the advantages of the present invention are:

[0029] 1. In this solution, the driving rod transmits the grinding rod through the meshing between the first synchronous gear and the second synchronous gear, and the grinding rod drives the grinding wheel to rotate to grind and polish the welding part of the steel bar, thereby avoiding the situation where the staff is injured by burrs when taking it;

[0030] 2. In this solution, when the protruding end of the cam is away from the convex edge plate, the reset spring releases its elastic force and moves back to the original position through the convex edge plate. The convex edge plate drives the knocking rod to move back and forth, so that the knocking rod uses the rubber head to knock on the steel bar welding point, thereby achieving the effect of welding strength detection;

[0031] 3. In this solution, the water pump draws water out of the cold water tank through the suction pipe and transports it to the nozzle through the water inlet pipe to cool the welding point, thereby achieving the effect of rapid cooling of the steel bar welding point.
