Abstract
The invention relates to a method for modeling the profile of external angle of repair end of steel tube, belonging to the steel tube end-processing area, which is mainly used in the end repair chamfering of straight joint resistance welding steel tube and seamless steel tube. And it can uniformly repair the end of welded middle and small straight resistance welding steel tube end. The method comprises: arranging the steel tube on the end repair device to be compressed by compress wheel; via external profile modeling device to track the outer wall of steel tube and process milling. The invention has simple structure, stable performance and easy installment, which can confirm uniform size of tube end and improve the end quality.
Description
Technical field
Shape process for end trimming of steel pipe exterior corner of the present invention belongs to the steel pipe manufacture field, and the pipe end that is mainly used in vertical masonry joint electric-resistance-welded steel pipe and seamless steel pipe is repaiied chamfer, particularly a kind of technology that middle or small straight electric-resistance-welded steel pipe pipe end behind the welding forming is evenly repaiied end.
Background technology
The general standard of pipe end root face size requires to be 1.6mm ± 0.8mm (GB/T9711.2-1999).In the production process of ERW, the pipe end ovality is relatively poor, and with the general end technology of repairing, in repairing the end process, owing to there is not the profiling equipment, it is bigger the root face dimensional discrepancy to occur, does not satisfy standard-required.In the production field of ERW, pipe end is repaiied the interior profiling of the general employing of end and is repaiied the uniformity that end technology guarantees pipe end root face size, but because the general lining inner burr removing apparatus of resistance weld pipe is in steel duct, the operator cannot see the burr removing situation, and can't adjust during start.Therefore, interior burr can't be removed fully or remove too much, generates the mother metal depression.Owing to be used for the inhomogeneities of profiling benchmark steel pipe inwall, generate the inhomogeneous of pipe end groove and root face.But the outer burr of steel pipe is removed then to finish and just is under the state of a control, can realize concordant scraping with mother metal.Therefore outer profiling technology can reach than better groove of the interior technology of following an example and root face.
Summary of the invention
The objective of the invention is to guarantee that pipe end root face size is even, improve pipe end groove and root face quality.
The objective of the invention is to reach by following measure, it utilizes outer wall of steel pipe, following an example by the wheel control of following an example, constant to reach pipe end root face size uniform for cutter and tube wall relative position, and the wheel of following an example is close to tube end outer wall in repairing the end process, and realization is followed an example when repairing end device rotation milling.
Shape process for end trimming of steel pipe exterior corner of the present invention is that steel pipe is transported on the support, with pressing mold steel pipe is fixed steel pipe, one end face of steel pipe is close to by on the End polishing machine, End polishing machine is made up of copying device, knife adjusting device, track-type facilities, contour wheel in repairing the end process near the pipe end outer wall, when repairing the end device rotary cutting, realize profiling,, can realize regulating the pretightning force of contour wheel tube wall by regulating stage clip lid and spring.
Knife adjusting device can slide on guide rail, and copying device is installed on the knife adjusting device and slides with knife adjusting device, and copying device is made up of pinch roller and bearing, and knife adjusting device is made up of tool rest, stage clip lid, spring cup; Track-type facilities is made up of slide and pressing plate, contour wheel and imitation-shaped knife are fixed on the tool rest, and can on slide, slide together, spring housing is on the spring shaft that connects together with tool rest, the active force of spring is delivered on the contour wheel by spring shaft, tool rest, make contour wheel in repairing the end process near the pipe end outer wall.Reality profiling when repairing the end device rotary cutting.By regulating stage clip lid and spring, can realize regulating the pretightning force of contour wheel to tube wall.
Outer wall of steel pipe is followed the tracks of and carried out planing operation by outer copying device, obtain the steel pipe that the welded tube technological requirement has even root face.
The present invention is reasonable in design, can avoid the uneven phenomenon of pipe end root face size, and is more even through the steel pipe root face size of repairing end exterior angle profiling technology, quality is more stable, can reach than the better effect of the requirement of standard.
