Abstract

1,144,269. Bending tubes. HILGERS MASCHINEN - UND APPARATE - BAUANSTALT m.b.H. 22 Sept., 1967 [22 Sept., 1966], No. 43200/67. Heading B3E. [Also in Division G3] In a pipe bending machine with a numerical control system, the numerical control system includes control means which are adjustable to compensate for characteristics of the machine and/or workpiece which would otherwise cause the bent form of a resulting bent pipe to differ from the form specified by the input data to the numerical control system. The controls are used to modify the movements of the machine to take account of spring-back of the pipe at the end of the bending movement or over-run of the pipe feeding carriage and to modify the position of the carriage relative to the pipe to allow for the physical size of the bending former.
