Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe production equipment, in particular to a spiral welding five-roller automatic leveling device. Background Art

[0002] When spiral welded steel pipes are butt-welded during material change, the steel plate has waves and needs to be leveled with a leveling machine. Currently, the five-roll leveling machine used for spiral welded steel pipes is manually pressed down. When pressed down, the left and right cylinders are unevenly stressed, the steel plate has slight waves, and the leveling effect is poor. In order to ensure stable forming and not affect product quality, a pad is usually added to the five-roll leveling base (the pad thickness is selected according to the different thickness of the steel plate). However, due to the inconsistent pressing action of the left and right cylinders, the five-roller shaft is broken due to the large inclination angle, which affects product quality and has a high equipment failure rate.

Detailed Embodiment

[0017] As Figures 1-3 shown, a spiral welded five-roll automatic leveling device includes a bottom plate 1 and brackets 2 connected to both ends of the top surface of the bottom plate 1. Two oil cylinders 3 are installed on the top of each of the two brackets 2. The oil cylinders 3 are connected to the top of the brackets 2 through a mounting plate 12, and the piston ends of the oil cylinders 3 penetrate through the mounting plate 12 and are connected to a lifting plate 4.

[0018] The lifting plate 4 is slidably connected to the bracket 2. Two sets of sliding plates 17 are provided on the front and rear end faces of the lifting plate 4. The lifting plate 4 clamps the bracket 2 through the sliding plates 17 and is slidably connected to the bracket 2.

[0019] Both ends of the bottom of the lifting plate 4 are connected with lower extension plates 5. An upper five-roll shaft 6 is rotatably connected between the two lower extension plates 5. A lower five-roll shaft 7 is provided below the upper five-roll shaft 6. Both ends of the lower five-roll shaft 7 are respectively rotatably connected to two fixing plates 8, and the fixing plates 8 are connected to the bottom plate 1.

[0020] A connecting rod 9 is provided between the piston ends of the two oil cylinders 3 in the same horizontal row, and the two ends of the connecting rod 9 are respectively hinged on the piston ends of the two oil cylinders 3. An electronic level 10 is connected to the middle position of the two connecting rods 9 through a universal assembly, and the electronic level 10 is connected to a touch screen controller 11. The universal assembly includes a vertical pole 14 fixed on the connecting rod 9, and a universal ball 15 is connected to the top of the pole 14. Universal sleeves 16 are respectively installed on the four corners of the bottom of the electronic level 10, and the universal sleeves 16 are sleeved on the universal ball 15. When one of the oil cylinders 3 is out of sync with the other oil cylinders, the connecting rod 9 will tilt, causing the electronic level 10 to no longer remain horizontal, and the touch screen controller 11 will immediately stop the operation of the oil cylinder 3 to prevent damage to the equipment.
