[0001] The present invention relates to the technical field of roll repair welding, and specifically to submerged arc welding equipment. Background Art

[0002] When repairing a roll, the entire roll surface of the old roll is machined on a lathe to clean the oil stain layer on the roll surface. The cleaned roll needs to be placed in a heating furnace for heating to increase the strength of the roll. After the preliminary treatment, surfacing welding of the roll surface becomes a key link. At this time, the submerged arc welding equipment, with its unique advantages such as stable welding process, high weld quality, and high production efficiency, plays an irreplaceable role in roll surfacing welding, meeting the stringent requirements for high-quality welding in roll repair and promoting the progress of roll repair technology.

[0015] Working principle: When the submerged arc welding equipment is needed, first lift the roller to be welded and repaired into the interior of the welding box by a crane. Then, start the second hydraulic cylinder. The output end of the second hydraulic cylinder can drive the moving block to slide on the outer wall of the welding box, thereby driving the rack to move. Through meshing connection, the second gear is driven to rotate, so that the moving blocks on both sides of the outer wall of the welding box slide relatively. The connecting block can drive the positioning frame to slide on the inner wall of the welding box through the chute, thereby positioning the position of the roller, realizing flexible positioning of rollers of different lengths, ensuring the accuracy of subsequent welding. And start the first hydraulic cylinder. The output end of the first hydraulic cylinder can pull the moving plate to slide on the inner wall of the rotating sleeve through the transmission disc. The moving plate can drive the movable plate to move synchronously through the fixed plate, and then drive the clamping block to slide centrically on the inner wall of the support frame, thereby clamping and fixing both ends of the roller to ensure stability during welding. Position the welding position of the roller by the position where the moving positioning frame slides on the inner wall of the carriage. The solder pipe lowers the solder in the solder tank to the welding position and welds it through the welding head. At the same time, start the first motor. The output end of the first motor can drive the first gear to rotate, so as to drive the rotating sleeve to rotate inside the positioning frame through the reverse force with the toothed ring, thereby driving the roller to rotate, further improving the stability and flexibility of welding. After welding is completed, start the second motor. The output end of the second motor can drive the transmission column to rotate, and then drive the crank to rotate. The crank can drive the moving block to slide on the inner wall of the material receiving frame, thereby driving the positioning frame to move synchronously through the inclined block. And when the inclined block slides downward, it can drive the positioning column to slide inside the material receiving frame. The spring can drive the inclined block to vibrate, thereby driving the roller clamped by the clamping block to vibrate, so that the solder residue on the roller falls into the material receiving frame. At the same time, the vibration of the inclined block can guide the material residue to the position of the discharge port. After pulling open the clapboard, the material residue is recycled, improving the welding quality and avoiding residue accumulation.

[0016] The present invention provides a submerged arc welding equipment. It has the following beneficial effects: 1. By starting the first hydraulic cylinder, pulling the moving plate to slide with the help of the transmission disc, driving the movable plate to move through the fixed plate, and then making the clamping block slide centrically, the two ends of the roller are clamped and fixed. At the same time, driving the fixed roller to rotate through the first motor, so as to avoid the roller shaking during welding and adjust the welding angle, improving the welding quality and flexibility.

[0017] 2. By activating the second hydraulic cylinder, the present invention drives the moving block to slide on the outer wall of the welding box, thereby driving the rack to move. Through meshing connection, the second gear is driven to rotate, causing the moving blocks on both sides of the outer wall of the welding box to slide relative to each other. The connecting block drives the positioning frame to slide on the inner wall of the welding box through the chute, thereby positioning the position of the roll, achieving flexible positioning of rolls of different lengths, and ensuring the accuracy of subsequent welding.

[0018] 3. By activating the second motor, the output end of which drives the transmission column to rotate, thereby driving the crank to rotate, causing the moving block to slide on the inner wall of the receiving frame. Through the inclined block, the positioning frame is driven to move synchronously. When the inclined block slides down, it drives the positioning column to slide in the receiving frame, and the inclined block is vibrated by the spring to shake off the solder residues on the roll. At the same time, the residues are guided to the discharge port, and the recovery can be achieved by opening the closing plate, improving the welding quality and the recovery of solder, and reducing the welding cost.
