Description

Technical Field

[0001] The invention relates to the technical field of steel drum production equipment, and in particular to a steel drum welding and forming device. Background Art

[0002] In the traditional steel drum production process, the forming and welding of the rolled plate are two independent and separate processes. First, the flat steel is rolled into a cylindrical shape by a plate rolling machine to form the initial shape of the steel drum. This process is usually completed by a special plate rolling equipment. After the plate rolling is completed, the formed cylindrical rolled plate needs to be taken out of the plate rolling machine and transferred to another special welding equipment for welding the butt joint. Although this step-by-step operation can meet the production needs to a certain extent, it has many shortcomings, especially in terms of production efficiency and product quality.

[0003] Since the plate rolling and welding processes are carried out on different equipment, each production needs to be done manually or mechanically to take the plate out of the plate rolling machine and transfer it to the welding equipment.

The pop-up mechanism 354 includes a top plate 3541, a switch 3542 is installed on the top plate 3541, a stopper 3544 is installed at the bottom of the top plate 3541, and a sliding rod 3543 for pressing the switch 3542 is installed on the top of the stopper 3544. The switch 3542 is electrically connected to the first servo motor 211, and the sliding rod 3543 is sleeved in the top plate 3541, and the sliding rod 3543 is slidably connected to the top plate 3541.

[0023] The profile roller 212 in the plate rolling mechanism is driven by the first servo motor 211. After entering the plate rolling machine, the flat steel passes through the gap between the profile roller 212 and the rubber roller 213 below, and is gradually rolled into a cylindrical shape. The first servo motor 211 continues to rotate, thereby driving the cylindrical steel to continue to rotate. The second hydraulic cylinder 331 is actuated to drive the welding mechanism 34 and the positioning mechanism 35 to descend to a position close to the plate rolling, in preparation for subsequent processes. The second servo motor 32 drives the first screw rod 31 to rotate, so that the welding mechanism 34 and the positioning mechanism 35 on both sides move along the screw rod toward the plate rolling, gradually approaching the butt joint of the plate rolling. The fifth hydraulic cylinder 351 pushes the stopper 3544 to contact until the stopper 3544 accurately falls into the butt joint of the plate rolling. When the stopper 3544 completely enters the butt joint, the sliding rod 3543 releases the pressure on the switch 3542, triggering the switch signal, causing the first servo motor 211 to stop running, so that the roll plate stops at the set position. The switch 3542 is a switch that controls the first servo motor 211 to stop, and has no start function. At this time, the butt joint of the roll plate is in the correct welding position. In order to ensure that the butt joint can be tightly closed, the third hydraulic cylinder 333 pushes the connecting plate 337 so that the butt joint of the roll plate overlaps tightly. In this process, the butt joint is squeezed and moved upward to ensure that it is completely closed. The fifth hydraulic cylinder 351 is controlled to drive the ejection mechanism 354 to reset to provide a position for welding. The fourth hydraulic cylinder 348 drives the first connecting arm 3413 and the first connecting rod 341 in the welding machine mechanism 34, so that the welding head 346 can accurately contact the butt joint of the roll plate. Once the welding head 346 is in place, the butt joint of the roll plate begins to be welded. During the welding process, the welding head 346 moves smoothly along the butt joint, ensuring the welding quality. Specifically, the fourth servo motor 3415 is driven to drive the third screw rod 344 to rotate, thereby driving the second movable block 347 to approach the butt joint until the welding head 346 contacts the butt joint, and further drives the third servo motor 349 to drive the second screw rod 343 to rotate. Since the second screw rod 343 is provided with a first movable block 345, and the two are also connected by threads, the rotation of the second screw rod 343 will cause the first movable block 345 to move in a direction perpendicular to the butt joint. As the third servo motor 349 continues to work, the welding head 346 moves smoothly along the butt joint driven by the second movable block 347 to perform the welding operation. After the welding is completed, the first hydraulic cylinder 215 is controlled to drive the rubber roller 213 to move downward, release the welded roll, and provide enough space for the staff to take the finished product out of the roll mechanism 2. The telescopic function of the first telescopic rod 3412 and the second telescopic rod cooperates with the telescopic function of the second hydraulic cylinder 331 in the vertical direction to enable the welding mechanism 3 to adapt to cylindrical rolls of different specifications.

[0024] Further, as a preferred embodiment of the present invention but not a limitation, a support mechanism 22 is installed at one end of the pressing roller 212, and the support mechanism 22 includes a flip frame 221, and support rods 223 are hinged at both ends of the flip frame 221, and the support rods 223 are fixedly connected to the casing 1. The flip frame 221 is installed with a limiting mechanism 222, and the limiting mechanism 222 includes a sleeve frame 2221, and an arc block 2222 is arranged in the sleeve frame 2221, and the arc block 2222 is slidingly connected to the inner wall of the sleeve frame 2221, and a handle 2223 is sleeved on the top of the sleeve frame 2221, and the handle 2223 is threadedly connected to the sleeve frame 2221, one end of the handle 2223 is arranged in the sleeve frame 2221, and one end of the handle 2223 is arranged in the arc block 2222, and the arc block 2222 is rotatably connected to the handle 2223. When it is necessary to support the profiling roller 212, the operator can rotate the handle 2223 to make the arc block 2222 slide downward along the inner wall of the sleeve frame 2221 and close to the profiling roller 212. At this time, the arc block 2222 applies a supporting force to the profiling roller 212, sharing the pressure of the profiling roller 212 from bottom to top, and ensuring the stability during the rolling process. When the welding is completed and the cylindrical roll needs to be taken out, the operator can rotate the handle 2223 in the opposite direction to make the arc block 2222 slide upward along the inner wall of the sleeve frame 2221 and away from the profiling roller 212. At this time, the arc block 2222 no longer applies a supporting force to the profiling roller 212, and one end of the profiling roller 212 is in a suspended state. Once one end of the profiling roller 212 is released, the operator can manually flip the flip frame 221 to make the sleeve frame 2221 completely out of the profiling roller 212, providing enough space for taking out the welded cylindrical roll.

[0025] Further, as a preferred embodiment of the present invention but not a limitation, the inner curvature of the arc block 2222 is consistent with the curvature of the rotating shaft of the embossing roller 212, and a number of rollers 2224 are installed on the inner curvature side of the arc block 2222. The inner curvature of the arc block 2222 is designed to be completely consistent with the curvature of the rotating shaft of the embossing roller 212. This ensures that the arc block 2222 can fit tightly against the rotating shaft of the embossing roller 212 and provide more stable support. A number of rollers 2224 are installed on the inner curvature side of the arc block 2222. These rollers 2224 not only reduce the friction between the arc block 2222 and the rotating shaft of the embossing roller 212, but also improve the smoothness of the operation. By reducing friction, the rollers 2224 help to extend the service life of the arc block 2222 and the rotating shaft of the embossing roller 212, and reduce the cost and frequency of equipment maintenance.

[0026] Furthermore, as a preferred embodiment of the present invention but not a limitation, the side wall of the first screw rod 31 is provided with two threads in opposite directions. The bidirectional thread design enables the steel barrel clamps 338 on both sides to move inward at the same time when the first screw rod 31 rotates, and accurately clamps the cylindrical roll plate. This synchronous movement ensures the position consistency of the roll plate during the clamping process, and avoids deformation or displacement caused by uneven force on one side.

[0027] Further, as a preferred embodiment of the present invention but not a limitation, the connecting plate 337 is provided with at least one second threaded hole 3371, the steel drum fixture 338 is provided with a third threaded hole 3383 matching the second threaded hole 3371, the third threaded hole 3383 is sleeved with a bolt 3382, and the second threaded hole 3371 and the third threaded hole 3383 are both threadedly connected with the bolt 3382. Through the bolt connection, the steel drum fixture 338 can be quickly disassembled and installed without complex tools or professional skills. This design greatly shortens the time for equipment maintenance and replacement and improves production efficiency. The modular design allows each component to be maintained or replaced independently. According to different coil specifications or production requirements, different types of steel drum fixtures 338 can be easily adjusted or replaced, which increases the adaptability and flexibility of the equipment.

[0028] Further, as a preferred embodiment of the present invention but not a limitation, an arc groove 3381 is provided on one side of the steel drum clamp 338. The arc groove 3381 is closely fitted with the outer circumferential surface of the rolled plate, which enhances the stability of the clamping and reduces the possible shaking or displacement during the welding process, thereby improving the welding quality.

[0029] Further, as a preferred embodiment of the present invention but not a limitation, the top plate 3541 is provided with a plurality of through slots 3545, and a clamping block 3546 is arranged in the through slots 3545. The clamping block 3546 is slidably connected to the through slots 3545, and a spring 3547 is arranged on the outer sleeve of the clamping block 3546. One end of the clamping block 3546 is fixedly connected to the block 3544. When the fifth hydraulic cylinder 351 pushes the block 3544 to approach the butt joint of the roll plate, the block 3546 starts to slide along the through slots 3545, and the spring 3547 is compressed. The design of the spring 3547 provides a good buffering effect, reduces the impact force that may be generated when the block 3544 enters the butt joint, and protects the equipment and the roll plate from damage. The spring 3547 can quickly push the block 3544 into the butt joint.

[0030] Further, as a preferred embodiment of the present invention but not limited thereto, a slanted section 3548 is provided on one side of the stopper 3544. The slanted section 3548 has a self-guiding function, which can ensure that the stopper 3544 can easily withdraw from the butt joint when the butt joint is closed.

[0031] Further, as a preferred embodiment of the present invention but not limited thereto, the first telescopic rod 3412 includes a first rod body 3416, the first rod body 3416 is provided with a first sleeve 3418, the first sleeve 3418 is slidably connected to the first rod body 3416, the side wall of the first sleeve 3418 is provided with a second positioning pin 3417, and the second positioning pin 3417 is threadedly connected to the first sleeve 3418. The second telescopic rod includes a second rod body 357, the second rod body 357 is provided with a second sleeve 356, the second sleeve 356 is slidably connected to the second rod body 357, the side wall of the second sleeve 356 is provided with a fourth positioning pin 355, and the fourth positioning pin 355 is threadedly connected to the second sleeve 356. The operator can manually rotate the positioning pin to withdraw the positioning pin, and then push or pull out the rod body as needed to adjust the length of the telescopic rod. After adjusting to the desired length, the positioning pin is rotated again to make it abut against the rod body to achieve position locking, ensuring that the telescopic rod remains stable during operation.

[0032] Specifically, the working principle of the present invention is as follows: In the steel drum welding and forming device, the flat steel is first gradually rolled into a cylindrical shape through the gap between the profiling roller 212 and the rubber roller 213 below. The first servo motor 211 drives the profiling roller 212 to rotate, so that the cylindrical steel continues to rotate and moves to the welding position. At the same time, the second hydraulic cylinder 331 is actuated to drive the welding mechanism 34 and the positioning mechanism 35 to descend to a position close to the plate roll to prepare for subsequent processes. The second servo motor 32 drives the first screw rod 31 to rotate, so that the welding mechanism 34 and the positioning mechanism 35 on both sides move along the screw rod toward the plate roll, gradually approaching the butt joint of the plate roll to ensure precise alignment.

[0033] The fifth hydraulic cylinder 351 pushes the stopper 3544 to contact, and the sliding rod 3543 presses the switch 3542. At this time, once the sliding rod 3543 does not press the switch 3542, the switch 3542 will control the first servo motor 211 to stop, and the stopper 3544 will fall accurately into the butt joint of the roll plate. When the stopper 3544 completely enters the butt joint, the sliding rod 3543 releases the pressure on the switch 3542, triggering the switch signal, causing the first servo motor 211 to stop running, so that the roll plate stops at the set position. At this time, the third hydraulic cylinder 333 pushes the connecting plate 337, so that the butt joints of the roll plate overlap tightly together and ensure that they are completely closed. The arc groove 3381 design enhances the stability of the clamping and reduces the jitter or displacement that may occur during the welding process. The buffering effect provided by the spring 3547 reduces the impact force that may be generated when the stopper 3544 enters the butt joint, protecting the equipment and the roll plate from damage.

[0034] Drive the fourth hydraulic cylinder 348 to put the welding head 346 in place and start welding the butt joint of the rolled plate. During the welding process, the fourth servo motor 3415 and the third servo motor 349 work together to make the welding head 346 move smoothly along the butt joint, ensuring the welding quality. After the welding is completed, control the first hydraulic cylinder 215 to drive the rubber roller 213 to move downward, release the welded rolled plate, and provide enough space for the staff to take the finished product out of the rolling plate mechanism 2. The design of the telescopic rod cooperates with the vertical telescopic function of the second hydraulic cylinder 331 to ensure that the welding mechanism 3 can adapt to cylindrical rolled plates of different specifications, thereby improving the flexibility and adaptability of the equipment. The design of the inclined section 3548 ensures that the block 3544 can easily withdraw from the butt joint, simplifying the operation process.

[0035] In summary, the present invention solves the problem of low production efficiency in the existing steel drum production process due to the need to take the rolled plate out of the plate rolling machine and transfer it to other equipment for welding.
