SU1532236A1 - Machine for butt resistance welding - Google Patents

Abstract

The invention relates to equipment for butt contact flash welding and can be used in the manufacture of various large-diameter tanks (over 2000 mm) of plastic materials with wall thicknesses ≤ ≤ 20 mm. The purpose of the invention is to improve the quality of centering, simplify the design of equipment and expand its technological capabilities. Inside the outer cylindrical body 1 there are concentrically placed two calibers 2, 3. One of them is made detachable in at least two parts, and the other has the ability to move during welding on rolling bearings. In both calibers, a base diameter D is made, to which the welded blanks 18, 19 are pressed from inside. The detachable caliber has actuators for displacing (opening) each of its parts. Between the caliber 3 and the body there is a support shell 7, which is moved by the drive beyond the zone of the separable caliber. When centering, the workpieces to be welded are based on the diameter D, which ensures an accurate alignment of the edges to be welded and allows welding of the annular joints of large-diameter pipe blanks from plastic materials at small wall thicknesses. 1 hp f-ly, 2 ill.
