[0002] Steel drums are a good loading tool. They can form a closed space to transfer liquids or other substances through a simple structure, and have good economic performance. Traditional steel drum manufacturing typically involves cutting, rolling, and welding, usually done manually. Some processes are discontinuous, such as handling after cutting, shaping during rolling, and fixing before welding. Even simple construction processes require a lot of manpower and resources. In addition, the rolling process requires completing the circle, and then removing the steel plate from the circle structure, which wastes a lot of time and space for storing unwelded plates, thus increasing production costs.

[0013] In one embodiment, the support plate is provided with a receiving baffle below the equipment support plane. The receiving baffle has a bent plate structure, and a discharge roller is provided on the side of the receiving baffle near the equipment support plane.

[0014] The beneficial effects of this invention are as follows: This invention provides an automated steel drum welding production line with a simple structure, good manufacturing efficiency, and reduced production costs. The specific implementation method is as follows: First, the sheet material is transported via conveyor belt and then guided above the ground by guide rods until the end of the sheet material falls between the clamping plate and the abutment plate. Then, the clamping motor is started to rotate the meshing wheel, which drives the meshing nut and the through threaded rod to rotate. The compression spring causes the support guide block to approach the connecting slide rod, thus completing the clamping of the clamping plate against the abutment plate. At the same time, the set guide angle can effectively guide the sheet material through the clamping plate and the abutment plate. After completion, the drive motor is started to rotate the sliding motor, which drives the rotating wheel to rotate. During the rotation of the rotating wheel, it is guided by the threaded screw rod until it abuts one side of the rectangular through groove. The rotating wheel continues to rotate. At this time, the rotating wheel is constrained by the rectangular block and can only push the threaded screw rod to move. This drives the threaded screw rod to the top of the sheet material until the end of the threaded screw rod is guided by the inclined guide groove to the polygonal rod. The polygonal rod enters the polygonal groove, and the rotating friction roller is stopped. The rolling into a barrel can then begin. At this time, the rotary motor is started, driving the polygonal rod to rotate the threaded rod. Under the action of the threaded rod, the threaded rod drives the pressing rod fixed on the fixed plate to rotate along the axis of the threaded rod. Since the other end of the pressing rod is supported by the support plate, the pressing rod is cylindrical during rotation. At this time, under the action of the pressing rod, the pressed plate is subjected to elastic force and material plasticity, bending along the outer periphery of the maximum rotation of the pressing rod. At the same time, during the rotation of the threaded rod, the pressing motor is started, rotating the outer arc pressing roller, driving the pressing slider to slide in the gap between the inner and outer arc rings, and simultaneously driving the end of the plate along the axis of the inner arc ring. The screw-in rod rotates along its axis until the clamping plate abuts the extension block. Due to the pushing action of the guide rod on the inclined surface of the clamping plate, the clamping plate is guided by the sliding through groove to the connecting slide rod and disengage from the plate. After the plate directly contacts the guide rod, the plate is pushed out into a cylinder by the pressing rods on both sides of the screw-in rod. Then, the lifting rod can be activated to drive the cutting blade through the cutting groove and the cutting blade of the abutment plate to cut the plate. After cutting, the guide rod and the abutment plate are still clamping the end of the plate, so they will not fall off. At this time, the welding gun can be inserted into the groove and the robotic arm can be used for welding. During the welding process, the reverse-rotating drive motor rotates the friction roller, which drives the rotating wheel to abut against the other side of the rectangular through groove in the rectangular block. This causes the threaded screw rod to disengage from the polygonal rod, thus detaching it from the inner cavity of the barrel. After complete detachment, the welding is finished. Then, the outer arc pressing roller is rotated in the opposite direction to return the abutment plate to its original position. During the repositioning process, when the abutment plate rotates to the top of the inner arc ring, the clamping plate is also guided by the sliding through groove to the connecting slide rod under the influence of gravity, thus completing its repositioning. It can then wait for the next plate fixing. The welded steel barrel falls onto the receiving stop under gravity and abuts against the discharge roller. When subsequent work such as adding a lid is needed, the discharge roller can be rotated to remove the steel barrel, completing the production of the steel barrel. Since a threaded insertion rod needs to be inserted after the plate reaches the guide angle through the guide rod, but the threaded insertion rod is basically at the rotation center of the abutment plate and may be interfered with by the movement of the plate, when the threaded insertion rod is inserted to the middle of the plate, the rotating sliding motor drives the abutment roller to rotate until it drives the guide rod on the extension block to rotate towards the support plane of the equipment. The plate can then approach the support plane based on the gap of the threaded insertion rod. After the threaded insertion rod is completed, the abutment roller is rotated in the opposite direction to return the guide rod to its original position, which solves the above problem.

[0015] The equipment has a simple structure and effectively optimizes the pre-welding preparation process by rotating and wrapping the plates into barrels. It simplifies the implementation, reduces the manufacturing cost of steel barrels from plates, and avoids the waste of space resources caused by the accumulation of semi-finished products. It has good practicality and economy, and is beneficial to the promotion and use of the equipment. Attached Figure Description

[0029] Beneficially, a receiving baffle 51 is provided below the support plate 25 near the equipment support plane. The receiving baffle 51 has a bent plate structure. A discharge roller 52 is provided on the side of the receiving baffle 51 near the equipment support plane to prevent the barrel material from falling directly and causing deformation. At the same time, it helps with intermittent conveying and improves the production efficiency of subsequent operations.

[0030] Working principle of this invention: First, the sheet material is transported via conveyor belt 1 and then continues to be transported above the ground via guide rod 33 until the end of the sheet material falls between clamping plate 36 and abutment plate 37. Then, clamping motor 372 is started to rotate meshing wheel 373, which drives meshing nut 3752 to rotate on threaded rod 375. The compression spring 3751 causes support guide block 374 to approach connecting slide rod 361, thus completing the compression of clamping plate 36 against abutment plate 37. At the same time, the set guide angle 371 can effectively guide the sheet material into the space between clamping plate 36 and abutment plate 37. After completion, drive motor 24 is started to rotate sliding motor. 341 drives the rotating wheel 231 to rotate. During the rotation of the rotating wheel 231, it is guided by the threaded screw rod 23 until it abuts one side of the rectangular through groove 211. The rotating wheel 231 continues to rotate. At this time, the rotating wheel 231 is constrained by the rectangular block 21 and can only push the threaded screw rod 23 to move. The threaded screw rod 23 can then be driven to pass through the top of the plate until the end of the threaded screw rod 23 is guided by the inclined guide groove 271 to the polygonal rod 274. The polygonal rod 274 passes into the polygonal groove 272. The rotating friction roller 241 stops, and the rolling into a barrel can begin. At this time, the rotary power motor 2741 is started, driving the polygonal rod 274 to rotate the threaded rod 23. Under the action of the threaded rod 23, the threaded rod 23 drives the pressing rod 26, which is fixed on the fixed plate 261, to rotate along the axis of the threaded rod 23. Since the other end of the pressing rod 26 is supported by the support plate 25, the pressing rod 26 is cylindrical during rotation. At this time, under the action of the pressing rod 26, the pressed plate is subjected to elastic force and material plasticity and bends along the outer periphery of the maximum rotation of the pressing rod 26. At the same time, during the rotation of the threaded rod 23, the pressing motor 352 is started, rotating the outer arc pressing roller 353, which drives the pressing slider 35 to slide in the gap between the inner arc ring 41 and the outer arc ring 42, and at the same time drives the end of the plate to rotate along the axis of the inner arc ring 41. The screw-in rod 23 rotates along its axis until the clamping plate 36 abuts against the extension block 333. Due to the pushing action of the guide rod 33 on the inclined surface of the clamping plate 36, the clamping plate 36 is guided by the sliding through groove 3761 to the connecting slide rod 361 and disengages from the clamping of the plate. After the plate directly contacts the guide rod 33, the plate is pushed out into a cylinder by the pressing rods 26 on both sides of the screw-in rod 23. Then, the lifting rod 32 can be activated to drive the cutting blade 31 to cut the plate through the cutting edge through groove 331 and the cutting edge through groove 39 of the abutment plate 37. After the cutting is completed, since the guide rod 33 and the abutment plate 37 are still at the end of the clamping plate 36, they will not fall off. At this time, the welding gun can be inserted through the groove 332 and the robotic arm can be used for welding. During the welding process, the reverse-rotating drive motor 24 rotates the friction roller 241, which drives the rotating wheel 231 to abut against the other side of the rectangular through groove 211 in the rectangular block 21. This drives the threaded screw rod 23 to disengage from the polygonal rod 274, thus disengaging it from the inner cavity of the barrel. After complete disengagement, the welding is also completed. Then, the outer arc pressing roller 353 can be rotated in the opposite direction to return the abutment plate 37 to its original position. During the return of the abutment plate 37, when it rotates to above the inner arc ring 41, the clamping plate 36 is also guided by the sliding through groove 3761 to the connecting slide rod 361 under the action of gravity, thus completing its return to its original position. It can then wait for the next fixing of the plate. The welded steel barrel falls onto the receiving stop 51 under the action of gravity and abuts against the discharge roller 52. When subsequent work such as adding a lid is required, the discharge roller 52 can be rotated to remove the steel barrel, thus completing the production of the steel barrel. Since the threaded rod 23 needs to be inserted after the plate reaches the guide angle 371 through the guide rod 33, the threaded rod 23 is basically at the rotation center of the abutment plate 37 and may be affected by the movement of the plate. When the threaded rod 23 is inserted to the middle of the plate, the rotary sliding motor 341 drives the abutment roller 342 to rotate until it drives the guide rod 33 on the extension block 333 to rotate towards the support plane of the equipment. The plate can then approach the support plane based on the gap of the threaded rod 23. After the threaded rod 23 is inserted, the abutment roller 342 is rotated in the opposite direction to return the guide rod 33 to its original position, which solves the above problem.
