Numerical control pipe bending machine

Abstract

The invention relates to the technical field of pipe bending machines, in particular to a numerical control pipe bending machine which comprises a main body support, sliding assemblies are slidably connected to the positions, close to the rear end, of the two sides of the outer surface of the upper end of the main body support, a fixing cylinder is fixedly connected to the front ends of the sliding assemblies, and a clamping mechanism is fixedly connected to the position, close to the rear end, of the interior of the fixing cylinder. The upper end and the lower end of the front side of the main body support are rotationally connected with movable frames, and the upper ends of the movable frames are movably connected with lifting mechanisms. The lifting mechanism and the clamping mechanism are arranged, the distance between the arc-shaped plates is adjusted by controlling a first motor to rotate forwards and backwards, then the height of a fixing roller and the height of a clamp are adjusted by controlling lifting of an oil cylinder, and therefore the pipe bending device can be matched with pipes with different pipe diameters, bending operation can be conducted on the pipes conveniently, frequent die replacement is not needed, and the production efficiency is improved. Operation is easy and convenient, and the practicability and convenience of the bending machine are improved.

Description

technical field [0001] The invention relates to the technical field of pipe bending machines, in particular to a numerical control pipe bending machine. Background technique [0002] The pipe bending machine is mainly used for the bending operation of steel pipes in electric power construction, boilers, bridges, ships, furniture, decoration, etc. It has the advantages of multiple functions, reasonable structure and simple operation. Used as a hydraulic jack, compared with CNC pipe bending equipment, it has the characteristics of cheap price and convenient use, and occupies a leading product position in the domestic pipe bending machine market. [0003] At present, the pipe bending machines in the prior art all use a pipe diameter corresponding to a bending die and a bending die. For pipes with different diameters, it is necessary to replace the matching bending die, and then use the rotation of the bending die. Bending the pipe to realize the bending operation of the pipe, ...

Problems solved by technology

[0003] At present, the pipe bending machines in the prior art all use a pipe diameter corresponding to a bending die and a bending die, and for pipes with different pipe diameters, it is necessary to replace the matching bending die, and then use the rotation of the bending die to achieve Bending the pipe to achieve the bending operation of the pipe. For bending pipes with different bending diameters formed on the same pipe bending machine, it is necessary to change the mold frequently. The operation is complicated, time-consuming and laborious, and it cannot be applied to pipes of different shapes Bending operation, which reduces the practicality and convenience of the bending machine
