Abstract

The invention discloses a special pipe bender of a chain frame, which can integrally mold the chair frame in one step, comprising a bender body. One end of the bender body is provided with an outrigger which is provided with a bender head; the bender head is movably provided with a spindle which is provided with a pipe bending die, a pipe bending arm and a transmission gear; the pipe bending arm is provided with a clamping oil cylinder; a piston rod of the clamping oil cylinder is provided with a clamping die holder which is provided with a clamping die; the bender body is provided with a spindle oil cylinder; a piston rod of the spindle oil cylinder is provided with a transmission rack which is engaged with the transmission gear; the back side of the outrigger is provided with a vertical avoiding groove used for avoiding the chair frame, and the trigger vertically penetrates through the avoiding groove a; and correspondingly, the transmission rack and the spindle oil cylinder are in inclined arrangement. The invention is mainly used for integrally molding chair frames.

Description

technical field [0001] The invention relates to a pipe bender, in particular to a special pipe bender for a chair frame. Background technique [0002] The current pipe bending machine dedicated to the chair frame, when processing the chair frame, due to the interference of the installation size of the machine head relative to the fuselage and the original structure of the fuselage, the chair frame cannot be processed as a whole at one time, and the chair frame usually needs to be divided into two parts. The two parts are respectively bent on a special pipe bender for the chair frame, and then welded to form the chair frame. This makes the production efficiency of the whole chair frame lower, and the strength and appearance quality of the chair frame are greatly affected. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a special pipe bending machine for the chair frame which can process and shape the chair frame ...
