Automatic tube bending machine

Abstract

The invention provides an automatic tube bending machine which comprises a rack, a driving device, a driving shaft, a rotating disc, a plurality of positioning rods, a positioning column, a sleeve plate and a pressing rod, wherein the driving device is used for providing power and is in transmission connection with the driving shaft; one end of the driving shaft is fixedly mounted in the center of the rotating disc; a plurality of positioning holes are formed in the circumferences with the center of the rotating disc as the circle center and different diameters; the positioning rods and the positioning column are detachably mounted inside positioning holes in the circumference with the same diameter; the sleeve plate is an annular steel plate with a notch; the sleeve plate sleeves the outer sides of the positioning rods; two ends of the sleeve plate are fixed on the positioning column; a fixing device for fixing a tube is detachably mounted on the rotating disc; the fixing device is positioned on the outer side of the sleeve plate; the pressing rod is mounted on the rack; a pressing head is arranged at the end part of the pressing rod; the gap between the pressing head and the sleeve plate is identical to the diameter of the tube. As the positioning holes are formed in circumferences with different diameters on the rotating disc, bent tubes with different diameters can be all produced without replacing any component, the operation is convenient and rapid, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of pipe bending equipment, in particular to a pipe bending machine. Background technique [0002] Pipe bending equipment is a device that bends straight pipes into curved pipes according to construction or production needs. There are many types of pipe bending equipment in the prior art, and manual pipe bending machines require a lot of manpower to operate, and the production efficiency is low; existing There are also reports about automatic pipe benders in the technology, but a pipe bender can only produce bends with a certain bending radius, and it is necessary to replace equipment or parts to prepare another bend with a medium radius, which is also cumbersome. , and the production efficiency is also very low. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overcome the deficiency that the pipe bender in the prior art can only produce a bend with a s...
