Micro heat pipe electric-current-assisted rotary draw bending forming device and method

Abstract

The invention provides a micro heat pipe electric-current-assisted rotary draw bending forming device and method, and belongs to the technical field of bent pipe manufacture plastic micro forming. Themicro heat pipe electric-current-assisted rotary draw bending forming device comprises a rotary draw bending forming machine, a mold assembly and a forming assisting power system. The mold assembly is installed on the rotary draw bending forming machine. The rotary draw bending forming machine is mainly composed of a fixed bottom plate, a pipe pressing assembly, a pipe bending assembly, a rotating shaft, a rotation drive mechanism and a control system. The rotating shaft is installed on the pipe bending assembly and is matched with a shaft hole in the fixed bottom plate. The pipe pressing assembly is fixed to the fixed bottom plate. The forming method includes the steps that firstly, the mold assembly is selected; secondly, a power-on loop is established; thirdly, parameters are set; fourthly, micro heat pipe blank heating and bending forming are conducted; fifthly, a bent piece is obtained through bending forming; and sixthly, the bent piece is taken out. By means of the micro heat pipe electric-current-assisted rotary draw bending forming device and method, micro heat pipe bending forming defects and forming precision can be controlled, and the problem that the heat conduction capacity is lowered after micro heat pipe bending is solved.
