Pipe bending machine

Abstract

The invention discloses a pipe bending machine. The pipe bending machine comprises a machine body, a machine head, a moving base, a feeding device, a servo motor, a pneumatic control power system and a PLC control system. The machine body comprises a longitudinal guide rail, and the moving base slides on the longitudinal guide rail. The machine head comprises an open type disc dual-gear transmission structure and an XY plane 180-degree pipe bending mechanism. The open type disc dual-gear transmission structure comprises an XZ plane 360-degree rotating mechanism and a pipe receiving device. The XY plane 180-degree pipe bending mechanism can rotate relative to the XZ plane 360-degree rotating mechanism. The XZ plane 360-degree rotating mechanism can drive the XY plane 180-degree pipe bending mechanism to rotate together. The XZ plane 360-degree rotating mechanism comprises a V-shaped opening. The machine head comprises a left machine head body and a right machine head body which are arranged on two sides of the longitudinal guide rail. At least one machine head body is provided with an up-down adjusting mechanism. The left machine head body and the right machine head body can bend pipes simultaneously according to different paths through PLC control. The two machine head bodies are used for automatically bending pipes at the same time, so that efficiency is high. The machine head on one side can be vertically adjusted to achieve avoidance, interference is avoided, and the shortest linear section of the middle of a bent pipe is obtained.

Description

technical field [0001] The invention relates to the field of pipe benders for bending metal long hard pipes, in particular to a pipe bender for bending steel pipes and aluminum pipes in the automobile and automobile air-conditioning industries. Background technique [0002] For very long and thin automobile brake pipes and automobile air-conditioning pipe fittings, the current pipe bending machine is equipped with a head, and it is impossible to complete a complete long pipe bending product at one time, so currently for such pipes, absolutely Most of them are bent by manual pipe bending machines, the processing devices are complicated, the efficiency is low, and the processing quality of pipe fittings cannot be guaranteed. [0003] Even some so-called double-head pipe bending machines only move to another pipe bending head when the work of one head encounters bending interference, and then change the direction to bend the pipe to solve the interference problem. Although the...

Problems solved by technology

At the same time, the current pipe bending machine makes the bend by turning the pipe, which has great limitations, easily causes interference, low efficiency, low precision, and cannot solve the problem of reaching the shortest straight line when double-ended bending
