Definitions
- the invention relates to the production of large diameter pipes, in particular, to equipment for welding pipes using laser and hybrid laser-arc welding technologies.
- a technical solution is known that describes a mill for assembling and welding longitudinal seam pipes of large diameter of finite length, which is a welding stand with interchangeable mandrels for various sizes of tube blanks and equipped with an inner mandrel that is rigidly connected to the structural elements of the stand using a knife passing between open the edges of the tubular billet not yet crimped, and is equipped with rollers that rotate along the inner surface of the tubular billet as it passes through the cage (closest anal g from the description of the patent RU N ° 129853 Utility Model).
- Another technical problem is the inability to align the edges of the pipe billet during application, which determines the quality of the welded joint.
- the known mill is not adapted for applying a weld outside the tube billet using laser technology.
- the technical problem lies in the creation of an assembly and welding mill for the production of pipes, ensuring the application of a root weld using laser technology with the achievement of a technical result consisting in the possibility of applying a weld on pipes of various sizes when welding from the outside with guaranteed alignment of the edges of the pipe billet.
- the proposed assembly and welding mill for the production of pipes includes a means of feeding a tube billet with a transport roller table having a longitudinal axis and passing through an assembly and welding stand with radially arranged pressure roller beams designed to crimp a tube billet moving along the transport roller table, as well as a longitudinally oriented guide a knife, a cart with rollers with the possibility of rotation of the rollers on the inner surface of the tube stock when moving through the assembly a cooking stand, while a laser welding head or a hybrid laser-arc welding head with the ability to move in the transverse and vertical directions and around the longitudinal axis is mounted on the supporting elements of the assembly and welding stand, the trolley is rigidly connected to the supporting elements of the assembly and welding stand through a vertically oriented and a longitudinally directed connecting knife, a guide knife is designed to position the tube stock by opening the edges in the 12 o'clock position and mounted on supporting elements of the assembly and welding stand with the ability to move in the vertical direction and fixation, the trolley has an upward-facing pressure roller with the ability to
- the solution to the technical problem is associated with the presence of new tools in the assembly and welding stand, made in the form of a laser welding head or a hybrid laser-arc welding head and installed on the supporting elements of the assembly and welding stand with the possibility of vertical, horizontal movement in the transverse direction relative to the specified longitudinal axis assembly and welding stands and angular movement (around the longitudinal axis).
- the function of the pinch roller located inside the tube billet and the vertically located roller beam ensures the alignment of the edges of the tube billet relative to each other, preceding the overlap of the weld.
- the alignment of the edges of the tubular workpiece occurs on the upper and lower sides.
- the proposed mill has the property of universality, because it is possible to weld it from the outside of the tube stock of various sizes due to the possibility of adjusting the height of the pressure roller to the stop in the inner surface of the tube stock.
- the present invention contains features that are also interconnected in constructive unity, making it possible to use a welding head mounted outside the tube stock regardless of its size.
- - figure 1 is a General view (side view);
- FIG. 2 is a General view (left view);
- FIG. 3 is a General view of the welding trolley (side view);
- FIG. 4 is a General view of the welding trolley (top view).
- the assembly and welding mill is an installed means 1 for supplying a tube billet 2 with a transport roller table 3, an assembly and welding stand 4 with pressure roller beams 5, a trolley 6, guide knives 7, 8, technological bridges 9 with welding power sources and welding placed on it materials (the position is not indicated).
- a hybrid hybrid laser-arc head 10 is also installed with a corrector system providing vertical, horizontal and inclined movement.
- a stop roller H and mechanisms 12 for adjusting the height of the pressure roller and welding head 10 are mounted on the trolley 6.
- Such mechanisms can be made in the form of hydraulic cylinders (not shown in the drawing).
- the welding trolley has standard equipment for detecting grooves and for pointing the welding head to the joint of the edges of the tube stock (not shown in the drawing). Near the cage 4 posted by the control post of the mill 13.
- the assembly and welding stand 4 is set up by moving the pressure roller beams 5, raising / lowering the thrust roller 11 using mechanisms 12, raising / lowering the welding head 10 with the corrector system and setting welding modes at the control station 13 Then, the formed tube billet 2 enters the mill, where it is positioned with a knife 7 by opening the edges for 12 hours; if necessary, the knife 7 increases the opening of the edges for the passage of the knife 8.
- the pipe billet is moved by the pipe feeding means 1 into the welding zone, while a trolley is inserted into the cavity of the pipe billet, forcing the rollers of the trolley 6 to rotate. Upon entering the working area, the tube billet is crimped by roller beams 5.
- the vertical roller beam associated with the hydraulic mechanism aligns the edges of the tube billet with respect to each other by applying force from the outside, while the thrust roller 11 aligns the edges from the inside.
- the remaining roller beams compress the billet to the edges, then the billet stops to guide the welding head 10 to the joint of the edges.
- a laser welding head or a hybrid laser-arc head is mounted on the supporting elements of the assembly-welding stand using a corrector system based on standard servo drives.
- the welding head is installed exactly in the center of the groove.
- the operator at the control station 13 checks and, if necessary, adjusts the welding conditions.
- the welding head imposes a continuous root seam from the outside of the tube billet (regardless of size) on pre-aligned edges.
