Abstract
The utility model relates to an on-line straight seam welded steel pipe clamping device. The one-line straight seam welded steel pipe clamping device is characterized in that two motor reducers, two lifters, to clamping rollers, two roller seats and two machine seats are included, the on-line straight seam welded steel pipe clamping device is fixed on a rolling machine base body through a beam, arranged behind a pre-welding extrusion forming working station welding cushion roller, the motor reducers drive the lifters, the clamping rollers are connected to the lifters, the clamping rollers are made to move, and surfaces of the clamping rollers are attached to the outer surface of a tube blank. Due to the fact that mechanical transmission is adopted to replace hydraulic transmission, the on-line straight seam welded steel pipe clamping device is low in failure rate, reliable in work, good in welding quality, and high in material yield, and saves time and labor.
Description
Technical field
The utility model belongs to steel pipes with straight moulding and welding technology field, relates to a kind of motor reducer that utilizes, and by lift, drives nip rolls to move, the equipment that steel pipes with straight weld seam is not snapped, particularly a kind of online steel pipes with straight pipe clamping device.
Background technology
At present, the CO 2 gas-shielded online prewelding of the many employings of domestic steel pipes with straight pipe inside weld, off-line outside weld welding, or the welding of submerged-arc welding on-line continuous, this kind of technique exists the problem that weld seam easily snaps.Especially large for high strength and thick-walled pipe screen resilience, to control more difficultly, problem is even more serious.Can only off-line repair welding after weld seam is cooling in order to improve its present situation, seriously restricted speed of production and production kind, affect welding quality and lumber recovery.
Summary of the invention
The utility model has overcome the defect of above-mentioned existence, and object is by adopting online nip rolls mechanical fine adjustment, realizing tube end sizing, and off-line after weld seam is cooling solves the red problem that under state, weld seam snaps of melting, and a kind of online steel pipes with straight pipe clamping device is provided.
The online steel pipes with straight pipe clamping device of the utility model content Description:
The online steel pipes with straight pipe clamping device of the utility model, it is characterized in that: online steel pipes with straight pipe clamping device by: two motor reducers, two lifts, two nip rolls, two roller seats and two supports form, and be fixed on milling train matrix by crossbeam, be arranged on after prewelding extrusion modling station bonding pad roll, motor reducer drives lift, nip rolls is connected on lift, and nip rolls is moved, and nip rolls surface label leans against on outer surface of tube blank.
The online steel pipes with straight pipe clamping device of the utility model, owing to having adopted machine driving, has replaced hydraulic drive, and fault rate is reduced, and reliable operation is time saving and energy saving, and welding quality is good, and lumber recovery is high.
Accompanying drawing explanation
Fig. 1 is online steel pipes with straight pipe clamping device structural representation;
In figure: the 1st, pipe, the 2nd, nip rolls, the 3rd, roller seat, the 4th, lift, the 5th, motor reducer, the 6th, support, the 7th, crossbeam, the 8th, milling train matrix.
The specific embodiment
The online steel pipes with straight pipe clamping device of the utility model is achieved in that below in conjunction with accompanying drawing and illustrates.
See Fig. 1, online steel pipes with straight pipe clamping device, by: two motor reducers 5, two lifts 4, two nip rolls 2, two roller seats 3 and two supports 6, formed, two motor reducers 5, two lifts 4, two nip rolls 2, two roller seats 3 and two supports 6 are fixed on milling train matrix 8 by crossbeam 7, be arranged on after prewelding extrusion modling station bonding pad roll, motor reducer 5 drives lift 4, nip rolls 2 is connected on lift 4, nip rolls 2 is moved, and nip rolls 2 surface labels lean against on pipe 1 outer surface.Finely tune and be adjusted to steel pipe requirement size, and bestow clamping force, realize outer diameter of steel pipes sizing, complete the function that weld seam does not snap.
The online steel pipes with straight pipe clamping device of the utility model, through experimental test speed of welding, by original 1.2M/min, be increased to 3M/min, greatly improved speed of welding, pipe thickness of slab is no more than 12mm by original maximum ga(u)ge and is increased to 20mm, increase steel pipe's production kind, improved again productivity ratio.
The online steel pipes with straight pipe clamping device of the utility model, owing to having adopted machine driving, has replaced hydraulic drive, and fault rate is reduced, and reliable operation is cost-saving, economize again people laborsaving, and welding quality is good, and lumber recovery is high.
