The manufacture craft of a kind of point of crutch steel pipe connection structure, described point of crutch steel pipe comprises two tube cylinders, two tube cylinders are connected by steel-casting each other, described steel-casting cross section is "X" shape, and form four connection edges by this " X " shape cross section longitudinal extension, two relative sides of tube cylinder are equipped with breach, and the manufacture craft of described point of crutch steel pipe connection structure comprises the steps:
A) utilize computer to carry out expansion setting-out to tube cylinder respectively respectively, draw expanded view;
B) adopt plane numerical controlled cutting machine to carry out Numerical control cutting blanking according to expanded view, and draw swaging line respectively;
C) each lower materials and parts are press-forming into tube cylinder along swaging line successively respectively on forcing press;
D) described steel-casting cast molding, and spark-out;
E) the axial cylinder in the breach both sides of two tube cylinders divides a crutch steel tube body structure along being connected with four groups of steel-casting respectively along splicing to weld to form;
One of the present utility model is optimized, divide crutch steel pipe connection structure after welding terminates, take postweld heat preservation slow cooling measure, namely adopt firing equipment or flame that crutch steel pipe connection structure will be divided to be heated to 200 DEG C ~ about 250 DEG C, suitably to improve the temperature of welding region, then cover some layers of asbestos cloth parcel and make it be incubated 1.5 hours-3 hours.
Optimize for one of the present utility model, described point of crutch steel pipe can be divided into the first crutch steel pipe, the second crutch steel pipe ... N crutch steel pipe, point crutch steel tube body be respectively welded longitudinally docks welding respectively successively.
The utility model is compared with background technology, have by the vertical baffle adopted in background technology is adjusted to steel-casting, actual shaping situation when intersecting double embrace according to tube cylinder, steel-casting is built out certain moulding, namely cross section is in " X " type, the tube cylinder of it and both sides is spliced be welded as a whole, and meet the circularity demand of both sides tube cylinder outer wall by making steel-casting; Certain space is welded for ensureing to have when the attachment weld of welded cast steel part with cylindrical shell, tube cylinder is offered breach, and the axial cylinder in the breach both sides of two tube cylinders extends rational distance along the stitching position extroversion with the connection edge of steel-casting, and make the weld seam docked be a straight line, thus automatic welding device can be adopted to carry out welding (as automatic submerged arc welding), not only substantially increase welding work efficiency, and ensure that the inherent quality of the requirement of weld seam full penetration and weld seam, and make appearance of weld attractive in appearance; After tube cylinder and steel-casting are assembled, composite member can be set level, when weld seam welds, adopt in inner side bottoming, the conventional soldering method of outside back chipping, not only convenient but also quick.
