Description

Technical Field

[0001] The invention relates to the technical field of spiral welded pipe manufacturing, in particular to a spiral welded pipe forming device. Background Art

[0002] Spiral welded pipe is made by rolling low-carbon carbon structural steel or low-alloy structural steel strip into a tube blank at a certain spiral angle (called forming angle), and then welding the tube seams. It can produce large-diameter steel pipes with narrower strip steel.

[0003] For example, a forming device for a stainless steel spiral welded pipe with publication number CN115555425A is provided with a reinforcement mechanism, which can reinforce the welds of the stainless steel spiral welded pipes together, making the welds tighter and not easily broken even under greater pressure, thereby improving the structural strength of the entire spiral welded pipe and enabling the spiral welded pipe to work normally under high pressure. However, in actual use, the manufacture of spiral welded pipes uses steel coils as raw materials, and certain dust or corrosion will be generated on the surface of the steel coils during the production process or storage process. Although the steel coils can be trimmed by a trimming machine to remove certain burrs and corrosion, the cleaning range of the steel coils is limited, and certain dust, burrs or corrosion will remain on the steel coils. If the steel coils are subsequently bent and welded, the presence of impurities or corrosion will affect the welding effect after the steel coils are bent, and the quality of the weld cannot be guaranteed, which in turn affects the mechanical properties and safety of the spiral welded pipes after manufacture, and there are certain defects in use.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: the spiral welded pipe forming device is provided with a straightening assembly on one side of the unloading mechanism at the top of the base, so that both sides of the steel coil can be polished and cleaned while the steel coil is straightened, so as to avoid dust and impurities adhering to both sides of the steel coil, and to clean the corrosive substances, so as to avoid the generation of gas and slag in the subsequent welding process of the steel coil, which affects the quality and strength of the weld, and can ensure the quality of welding and improve the quality of spiral welded pipe manufacturing;

[0026] 1. A straightening assembly is provided on one side of the discharge mechanism at the top of the base. When the spiral welded pipe is manufactured, the material is discharged through the discharge mechanism. The steel coil can pass through the straightening assembly, be sheared by the shearing machine, and then be bent by the bending machine. The steel coil is welded into a spiral welded pipe by the forming machine. When the steel coil is discharged, the driving motor is started to drive the rotating shaft to rotate, and the two rotating shafts are driven to rotate by the cooperation of the first bevel gear and the second bevel gear, so that the two straightening rollers rotate synchronously in opposite directions. The steel coil can be straightened by the rolling of the two straightening rollers. While the two rotating shafts on one side rotate, the rotating rod can be driven to rotate through the connection between the first pulley and the second pulley, so that the two grinding rollers rotate synchronously in opposite directions, so that the grinding roller can grind and clean the steel coil, and the rotating shaft on the upper side can drive the reciprocating screw to rotate through the connection between the third pulley and the fourth pulley, so that the movable sleeve moves back and forth, and the rotating plate can be driven by the movable sleeve Reciprocating movement, the rotating plate drives the positioning sleeve to slide outside the positioning rod to limit the position during the movement, and then the impurities cleaned above the steel coil can be blown off by the fan to avoid residual impurities affecting subsequent processing, and the impurities cleaned below the steel coil can fall directly. The diameter of the first pulley is larger than that of the second pulley, so that the rotation speed of the grinding roller is higher than that of the straightening roller, and the grinding roller and the straightening roller are not consistent in rotation speed, which affects the cleaning effect. The diameter of the third pulley is equal to the diameter of the fourth pulley, so that the reciprocating screw speed is consistent with the straightening roller speed, and the reciprocating speed of the fan is not too fast to affect the cleaning effect. The straightening assembly allows the steel coil to be straightened while grinding and cleaning both sides of the steel coil, avoiding dust and impurities adhering to both sides of the steel coil, and cleaning the corrosive substances, avoiding the generation of gas and slag in the subsequent welding process of the steel coil, which affects the quality and strength of the weld, and can ensure the quality of welding and improve the quality of spiral welded pipe manufacturing;

[0027] 2. The rotating plate can drive the movable rod to move back and forth when driving the fan to move back and forth. When the rotating plate and the fan move backward, the movable block on the movable rod slides inside the movable groove of the mounting plate. The movable groove is inclined so that the movable rod can move backward and upward, and the movable rod drives the limit sleeve to move and slide on the limit sleeve during the movement. The limit sleeve drives the limit block to slide inside the limit groove, so that the movement of the movable rod can be limited, so that the movable rod can only move in the vertical direction. After the movable rod moves upward, the rotating plate can be pulled to rotate between the movable sleeve and the positioning sleeve, thereby allowing the fan to rotate backward. When the fan moves forward, the movable rod moves downward, so that the rotating plate can be pushed to rotate downward, so that the fan can rotate forward when it moves forward, thereby allowing the fan to rotate in the direction of movement during the reciprocating movement, thereby preventing the fan from blowing in a direction perpendicular to the steel coil, so that the wind blown by the fan can be inclined to the steel coil, thereby improving the cleaning effect of impurities above the steel coil, thereby improving practicality.

[0028] 3. When straightening or cleaning steel coils of different thicknesses, starting the two hydraulic push rods can drive the movable plate to move. The movable plate can drive the sliding plate to slide inside the sliding groove while moving, and the movable plate can drive the upper rotating shaft to move when moving. After the upper rotating shaft moves, it can drive the mounting rod to slide inside the mounting groove, so that the connecting strip slides on the connecting groove outside the mounting rod, so that the movable plate can also be transmitted between the two rotating shafts after moving, so that the user can adjust the distance between the movable plate and the fixed plate according to the thickness of the processed steel coil, which is convenient for processing steel coils of different thicknesses and improves practicality.

The movable plate 202 moves and drives the sliding plate 204 to slide inside the sliding groove 203. The movable plate 202 can drive the upper rotating shaft 229 to move. After the upper rotating shaft 229 moves, it can drive the mounting rod 233 to slide inside the mounting groove 234, so that the connecting strip 235 slides on the connecting groove 236 outside the mounting rod 233. After the movable plate 202 moves, the two rotating shafts 229 can also transmit the transmission, so that the user can adjust the distance between the movable plate 202 and the fixed plate 201 according to the thickness of the processed steel coil 102.

When the rotating plate 217 drives the fan 218 to reciprocate, it can drive the movable rod 219 to reciprocate. When the rotating plate 217 and the fan 218 move backward, The movable block 223 on the movable rod 219 slides inside the movable groove 222 on the mounting plate 221. The movable groove 222 is tilted so that the movable rod 219 can move upward after moving backward, and the movable rod 219 drives the limiting sleeve 226 to move and slide on the limiting sleeve 226 during the movement. The limiting sleeve 226 drives the limiting block 225 to slide inside the limiting groove 224, so that the movement of the movable rod 219 can be limited, so that the movable rod 219 can only move in the vertical direction. After the movable rod 219 moves upward, it can pull the rotating plate 217 to rotate between the movable sleeve 214 and the positioning sleeve 216, so that the fan 218 can rotate backward. When the fan 218 moves forward, the movable rod 219 moves downward.This allows the rotating plate 217 to rotate downward, so that the fan 218 can rotate forward when moving forward, and further allows the fan 218 to rotate in the direction of movement during the reciprocating movement.
