Description

Technical Field

[0001] This invention relates to the technical field of product manufacturing, specifically to an integrated equipment for continuous rolling and welding of steel drum bodies. Background Technology

[0002] Steel drums are mainly made by rolling and welding plates. During this process, ribs can be pressed onto the surface of the drum body through a pressing structure to improve the supporting strength. During the manufacturing process of steel drums, it is usually necessary to weld the ends or use clamps for fixation. However, edge deformation is easily generated during fixation, resulting in misalignment of the drum body and affecting the fit of the lid. In some scenarios where good sealing performance is required, the welding effect is poor. Moreover, steel drums of different sizes and structures require the use of matching clamps, which increases manufacturing costs. Larger drums are more difficult to control deformation during clamping, which leads to the need for rounding after welding, resulting in low efficiency and affecting welding strength. Summary of the Invention

[0003] In order to solve the above-mentioned problems in the existing technology, the purpose of this invention is to provide a steel barrel body continuous rolling forming and welding integrated equipment with simple structure, effective fixation of barrels of different sizes, and good deformation control.

Therefore, the coiled component includes multiple sets of axially arrayed wrapping springs, and wrapping springs that are connected to torsion gear rings at both ends of the multiple sets of wrapping springs. A placement ring is provided between the opposite sides of the two sets of wrapping springs that are close to each other, and the inner circumference of the placement ring is provided with an open rotating annular groove-shaped placement groove.

[0005] In one embodiment, the pressing mechanism includes two sets of support plates. The support plates have a movable groove in the middle that is perpendicular to the support plane. A first rotating rod is provided between the two sets of opposite movable grooves. The end of the first rotating rod passes through and is slidably connected to the adjacent movable groove.

[0006] In one embodiment, the first rotating rod is provided with a plurality of pressing male rings on its periphery, and the second rotating rod is provided with a pressing female ring that cooperates with the pressing male rings on its periphery, for pressing the sheet metal structure into shape.

[0007] In one embodiment, a support plate is provided on the side of the support plate away from the opposite side of the two sets of support plates.

The fixing nut is rotatably connected to the rotating screw.

[0008] In one embodiment, a rotating component is further provided between the second rotating rod and the conveyor belt for rotating the pressed sheet material. The rotating component includes two sets of obliquely placed guide plates, with the flared ends of the two sets of guide plates facing the second rotating rod. The guide plates are fixedly connected to adjacent support columns by several connecting rods. Several placement grooves are provided in the middle of the guide plates along the length direction of the guide plates. Rotating rollers are provided in the placement grooves along the length direction of the placement grooves. Several auxiliary motors are also provided on the guide plates, and the auxiliary motors drive the adjacent rotating rollers to rotate.

[0009] In one embodiment, the multiple sets of rotating rollers are arranged in a series of smaller cross-sectional diameters as they approach the conveyor belt.

[0010] In one embodiment, a rotating support ring is also sleeved around the outer side of the placement ring. The rotating support ring has supporting sliding columns on both sides. Two sets of limiting groove guide rails are provided on the supporting plane along the axis of the wrapping spring. The limiting groove guide rails have a U-shaped groove structure. A sliding roller is also provided at one end of the supporting sliding column near the adjacent limiting groove guide rail. The sliding roller passes into the groove of the adjacent limiting groove guide rail.

[0011] In one embodiment, the torsion gear ring has a through-and rotatably connected support rotating tube in the middle. The support rotating tube is also provided with a plurality of gear motors. The gear motors are fixedly connected to the periphery of the support rotating tube by fixing rods. The gear motors are provided with meshing gears that mesh with the torsion gear ring. The support rotating tube has sliding columns on both sides. The torsion gear ring has extended support frames on both sides. The ends of the extended support frames are provided with sliding wheels that pass into the adjacent limiting groove guide rails.

[0012] In one embodiment, a welding mechanism is provided at the end of the coiled part away from the conveyor belt. The welding mechanism includes a guide rod with a welding gun at the end of the guide rod and a movable part on the guide rod for passing through the inner cavity of the wrapping spring.

[0013] In one embodiment, the movable component includes two sets of supporting movable rings. Supporting fixed posts supporting the supporting plane are provided on both sides of the supporting movable rings. The insertion rod passes through the inner ring of the supporting movable ring. A semi-circular arc-shaped ring through-groove is provided on the side plane of the supporting movable ring. A connecting plate is provided between the two sets of supporting movable rings. Two sets of sliding connecting posts are provided on both sides of the connecting plate near the adjacent supporting movable rings. The sliding connecting posts pass through and are slidably connected to the arc-shaped ring through-groove. Guide grooves are provided on both sides of the insertion rod. Two sets of rotating guide wheels are provided in the guide grooves. The rotating guide wheels pass through and are rotatably connected to the guide grooves. The rotation axis of the rotating guide wheels is rotatably connected to the connecting plate.

[0014] The beneficial effects of this invention are as follows: This invention is a simple structure that effectively fixes barrels of different sizes, while also providing good control over deformation. It is an integrated equipment for continuous rolling and welding of steel barrel bodies. The specific implementation method is as follows: The operator first rotates the fixed nuts on both sides of the first rotating rod to adjust the height of the rotating screw, which drives the lifting ring to push the first rotating rod to slide in the movable groove. After adjusting the distance between the first rotating rod and the second rotating rod to match the required pressing material, the operator starts the rotating motor. The rotating motor drives the second rotating rod to rotate. Through the compression with the first rotating rod and the cooperation of the pressing male and female rings, the material deforms, causing the internal stress to be released and bending. This causes the material to bend into a barrel shape while pressing ribs to strengthen the support performance. At the same time, due to the stress released by the material during the pressing process and the effect of the pressing, the deformation of the material at the ends is smaller than that in the middle, resulting in a smaller degree of curling. This causes the material to curl into an irregular teardrop shape. After the sheet material has completely passed between the first and second rotating rods, it falls into the rotating component. Since the sheet material is now circular with an opening, resembling an irregular teardrop shape, the auxiliary motor is started to drive the nearby rotating rollers to rotate, guiding the opening of the curled sheet material towards the conveyor belt. Because the curled sheet material is relatively uniform, and because different sheet materials are curled into different sizes of barrels, the rotating rollers, which move from the outside inwards towards the conveyor belt and reduce their cross-sectional diameter, can better contact the outer walls of different sheet materials. This prevents the curled sheet material from falling onto the conveyor belt after its opening is guided towards the conveyor belt, thus ensuring that the conveyor belt can transport it. After being transported and inserted into the wrapping springs in the coiling component, the ribs of the sheet material need to fall into the placement grooves within the placement rings for better coiling. After adjusting the spacing of the placement rings by moving the supporting sliding columns to match the position of the sheet material's ribs, a sliding column on the torsion gear ring near one end of the conveyor belt is fixed. The sliding wheel on the sliding column away from the conveyor belt slides within the limiting groove guide rail, causing a creeping motion that pushes multiple wrapping springs in the coiling component to compress and stretch, moving the coiled sheet material creeping to the center of the coiling component, waiting for the ribs in the coiled sheet material to move to... After the corresponding groove is placed, the sliding column can be stopped. The sliding column and sliding support are fixed by the sliding rollers and sliding wheels. At this time, the gear motor on the support rotating tube is started to drive the meshing gear to rotate the torsion gear ring. Under the rotation of the torsion gear ring, multiple sets of wrapping springs curl and reduce the diameter, while gradually wrapping the internal curled steel plate into a barrel. The advantage of doing this is that the uniform wrapping tension of the springs assists the curled steel plate to be directly formed into a round barrel to the maximum extent. At the same time, it can match different plate sizes and lengths, effectively solving the problem of roundness fixation before plate welding. Next, welding will be carried out. The push rod is guided and slid under the action of the rotating guide wheel in the guide groove, which drives the welding gun to enter the center of the plate wrapped with spring for welding. At the same time, since the plate will rotate at a partial tilt angle during the rolling process, the connecting plate can be slid down by the guide of the sliding connecting column through the arc ring through the groove on both sides of the support movable ring. This will drive the push rod to rotate circumferentially within the support movable ring, which makes it easy to adjust the position of the welding gun in the steel barrel. At the same time, since the welding gun welding method is barrel welding, the welding liquid can flow into both sides of the plate under the action of gravity, resulting in a higher welding flatness and better effect.

[0015] This equipment has a simple structure and effectively utilizes a coiled structure wrapped with springs to wrap the sheet material, achieving a fixed effect of coiling sheet material of different sizes and lengths into a bucket. It solves the deformation problem during the clamping process and better matches the bucket lid. It has good practicality and economy, which is beneficial to the promotion and use of the equipment.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention; that is, the described embodiments are merely some embodiments of the invention, and not all embodiments. The components of the embodiments of the invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0021] The following is combined with Figure 1-6The following describes a specific embodiment of the present invention: a continuous rolling and welding integrated equipment for steel drum bodies, including a conveyor belt 2. The conveyor belt 2 is a prior art technology and mainly realizes the transportation of objects. A pressing mechanism 1 is provided above the conveyor belt 2 away from the support plane. The pressing mechanism 1 is used to punch and form the plate. The plate is usually made of iron or other metal products. A coiling part 4 is provided at the transport outlet end of the conveyor belt 2 to help the plate be rolled into a circle for welding. Therefore, the coiled part 4 includes multiple sets of axially arrayed wrapping springs 41, and a torsion gear ring 44 is provided at both ends of the multiple sets of wrapping springs 41 to connect with the wrapping springs 41. A placement ring 42 is provided between the opposite sides of the two sets of wrapping springs 41. An open rotating annular groove-shaped placement groove 421 is provided on the inner side of the placement ring 42.

[0022] Beneficially, the pressing mechanism 1 includes two sets of support plates 12. The middle of the support plate 12 is provided with a movable groove 121 that is perpendicular to the support plane. A first rotating rod 14 is provided between the two sets of movable grooves 121. The end of the first rotating rod 14 passes through and is slidably connected to the adjacent movable groove 121. A second rotating rod 15 is provided on the side of the first rotating rod 14 that is close to the support plane. The end of the second rotating rod 15 passes through and is rotatably connected to the adjacent support plate 12. A rotary motor 16 is provided on the support plate 12 to drive the second rotating rod 15 to rotate. Support columns 13 supporting the support plane are provided on both sides of the support plate 12. The two sets of support plates 12 are fixed together by a main support beam 11.

[0023] Beneficially, the first rotating rod 14 is provided with several pressing male rings 141 around its periphery, and the second rotating rod 15 is provided with pressing female rings 151 that cooperate with the pressing male rings 141 around its periphery, for pressing the sheet material to form a structure. The pressing male rings 141 and pressing female rings 151 are mainly used to press the sheet material with ribs, so that the sheet material has protrusions or other structural changes and then curls, while increasing its compressive strength. This is the prior art and can be understood as the cooperation of protrusions and grooves.

[0024] Beneficially, a support plate 172 is provided on the side of the support plate 12 away from the opposite side of the two sets of support plates 12. Lifting rings 17 are sleeved at both ends of the first rotating rod 14. A rotating screw 171 is provided around the lifting ring 17. The rotating screw 171 passes through and is slidably connected to the support plate 172. A fixing nut 173 is provided on the side of the support plate 172 away from the support plane. The fixing nut 173 is fixed to the support plane but can rotate. The fixing nut 173 is rotatably connected to the rotating screw 171.

[0025] Beneficially, a rotating component 3 is also provided between the second rotating rod 15 and the conveyor belt 2 to rotate the pressed sheet material. The rotating component 3 includes two sets of obliquely placed guide plates 31, with the flared ends of the two sets of guide plates 31 facing the second rotating rod 15. The guide plates 31 are fixedly connected to adjacent support columns 13 by several connecting rods 331. Several placement grooves 311 are provided in the middle of the guide plates 31 along the length direction of the guide plates 31. Rotating rollers 32 are arranged in the placement grooves 311 along the length direction of the placement grooves 311. Several auxiliary motors 33 are also provided on the guide plates 31, and the auxiliary motors 33 drive the adjacent rotating rollers 32 to rotate. Specifically, the multiple sets of rotating rollers 32 have progressively smaller cross-sectional diameters as they approach the conveyor belt 2.

[0026] In practice, since the board is round and has an opening, which is similar to an irregular teardrop shape, the auxiliary motor 33 is started to drive the nearby rotating roller 32 to rotate, and the opening of the curled board is turned toward the conveyor belt 2. Since the curled board is relatively uniform, and since different boards are curled into different sizes of barrels, the rotating roller 32, which moves from the outside to the inside and approaches the conveyor belt 2 and reduces the cross-sectional diameter of the rotating roller 32, can better contact the outer wall of different boards.

[0027] Beneficially, a rotating support ring 43 is also sleeved around the outer side of the placement ring 42. Supporting sliding posts 431 are provided on both sides of the rotating support ring 43. Two sets of limiting groove guide rails 46 are provided on the supporting plane, arranged along the axis of the wrapping spring 41. The limiting groove guide rails 46 have a U-shaped groove structure. A sliding roller 432 is also provided at one end of the supporting sliding post 431 near the adjacent limiting groove guide rail 46. The sliding roller 432 passes into the groove of the adjacent limiting groove guide rail 46. A supporting rotating tube 441 is provided through and rotatably connected in the middle of the torsion gear ring 44. Several gear motors 44 are also provided on the supporting rotating tube 441. 2. The gear motor 442 is fixedly connected to the periphery of the supporting rotating tube 441 by the fixing rod 4421. The gear motor 442 is provided with a meshing gear 443, which meshes with the torsion gear ring 44. The supporting rotating tube 441 is provided with sliding columns 444 on both sides, and the torsion gear ring 44 is provided with extended support frames 45 on both sides. The end of the extended support frame 45 is provided with a sliding wheel 451, which passes into the adjacent limiting groove guide rail 46. Specifically, the sliding wheel 451 and the sliding roller 432 can be moved electrically or manually, preferably electrically for limiting movement and fixing, to reduce labor intensity.

[0028] Beneficially, a welding mechanism 5 is provided at the end of the coiled part 4 away from the conveyor belt 2. The welding mechanism 5 includes a guide rod 52, and a welding torch 53 is provided at the end of the guide rod 52. The welding torch 53 can be adjusted in length or insertion height as needed. If a stamping part is encountered, the insertion depth can be adjusted. For example, a robotic arm can be used to connect the welding torch 53 to move the insertion depth. This is existing technology. The present invention only provides a support structure. A movable part is provided on the guide rod 52 for inserting into the inner cavity of the wrapping spring 41. Specifically, the movable part includes two sets of supporting movable rings 51. Supporting movable rings 51 are provided on both sides with supporting fixed columns 55 supporting the supporting plane. A through-ring 52 is provided in the inner ring of the supporting movable ring 51. The side plane of the supporting movable ring 51 is provided with a semi-circular arc-shaped ring through-groove 512. A connecting plate 54 is provided between the two sets of supporting movable rings 51. Two sets of sliding connecting columns 542 are provided on both sides of the connecting plate 54 near the adjacent supporting movable rings 51. The sliding connecting columns 542 pass through and slide in the arc-shaped ring through-groove 512. Guide grooves 521 are provided on both sides of the through-rod 52. Two sets of rotating guide wheels 541 are provided in the guide grooves 521. The rotating guide wheels 541 pass through and roll in the guide grooves 521. The rotation axis of the rotating guide wheels 541 is rotatably connected to the connecting plate 54.

[0029] Working principle of this invention: The operator first rotates the fixing nuts 173 on both sides of the first rotating rod 14 to adjust the height of the rotating screw 171, which drives the lifting ring 17 to push the first rotating rod 14 to slide in the movable groove 121. After adjusting the distance between the first rotating rod 14 and the second rotating rod 15 to match the required pressing material, the operator starts the rotating motor 16. The rotating motor 16 drives the second rotating rod 15 to rotate. Through the interaction with the first rotating rod 14 and the cooperation of the pressing male ring 141 and the pressing female ring 151, the material deforms, causing the internal stress to be released and bending. This causes the material to bend into a barrel shape while pressing ribs to strengthen the support performance. At the same time, due to the stress released by the material during the pressing process and the effect of the pressing, the deformation of the material at the end is smaller than that in the middle, resulting in a smaller degree of curling. This causes the material to curl into an irregular teardrop shape. After the board has completely passed between the first rotating rod 14 and the second rotating rod 15, it falls into the rotating component 3. Since the board is round at this time and has an opening, which is similar to an irregular teardrop shape, the auxiliary motor 33 is started to drive the nearby rotating roller 32 to rotate, and the opening of the curled board is turned toward the conveyor belt 2. Since the curled board is relatively uniform, and since different boards are curled into different sizes of barrels, the rotating roller 32, which moves from the outside to the inside toward the conveyor belt 2 and reduces the cross-sectional diameter of the rotating roller 32, can better contact the outer wall of different boards. This prevents the board from falling onto the conveyor belt 2 after the opening of the curled board is turned toward the conveyor belt 2, so that the conveyor belt 2 cannot transport it. After being transported and inserted into the wrapping springs 41 in the coiling component 4, the ribs of the sheet material need to fall into the placement grooves 421 within the placement rings 42 for better coiling. After adjusting the spacing of the placement rings 42 using the movable support sliding column 431 to match the position of the sheet material's ribs, the sliding column 444 on the torsion gear ring 44 near one end of the conveyor belt 2 is fixed. The sliding wheel 451 on the sliding column 444 away from the conveyor belt 2 slides within the limiting groove guide rail 46, pushing the multiple wrapping springs 41 in the coiling component 4 in a peristaltic manner to compress and stretch them. This causes the coiled sheet material to move peristally to the middle of the coiling component 4, waiting for the ribs in the coiled sheet material to move to the corresponding position. After the corresponding placement groove 421 is completed, the sliding column 444 can be stopped. The sliding column 431 and the sliding column 444 are fixedly supported by the sliding roller 432 and the sliding wheel 451. At this time, the gear motor 442 on the support rotating tube 441 is started to drive the meshing gear 443 to rotate the torsion gear ring 44. Under the rotation of the torsion gear ring 44, multiple sets of wrapping springs 41 curl to reduce the diameter while gradually wrapping the internal curled steel plate into a barrel. The advantage of doing this is that the uniform wrapping tension of the springs assists the curled steel plate to be directly formed into a cylindrical shape to the maximum extent. At the same time, it can match different plate sizes and lengths, effectively solving the problem of roundness fixation before plate welding. Welding will then take place. The push rod 52 is guided and slid under the action of the rotating guide wheel 541 rotating in the guide groove 521, which drives the welding gun 53 to enter the center of the plate wrapped with the spring 41 for welding. At the same time, since the plate will rotate at a partial tilt angle during the rolling process of the coiled part 4, the connecting plate 54 can slide under the guidance of the sliding connecting column 542 through the arc ring through groove 512 on both sides of the supporting movable ring 51, which will drive the push rod 52 to rotate circumferentially within the supporting movable ring 51. This makes it easy to adjust the position of the welding gun 53 in the steel barrel. Since the welding method of the welding gun 53 is in-barrel welding, the welding liquid can flow into both sides of the plate under the action of gravity, resulting in a higher welding flatness and better effect.
