It is overpressurized, so that metal pipe material passes through flexible deformation to plastic deformation respectively, metal pipe material is finally bent into product；Existing skill
There are a kind of metal pipe material bending machines in art；But the metal pipe material bending machine Shortcomings of the prior art, on the one hand, metal tube
When material is directly placed on pressing plate, metal pipe material can not be fixed, metal pipe material, can be due to mechanical oscillation during apparatus for bending
Displacement is generated, to the offset of bending position on metal pipe material occur, so that the low qualified of product；On the other hand, existing
Metal pipe material bending machine generally pass through the dynamic elevating lever of tool and one does not have dynamic pressing plate to carry out bending operation,
When completing bending operation, the stroke that elevating lever needs power source to push is longer, so that making the speed of production reduces；The present invention is logical
Setting rack, pressing unit, transmission mechanism, clamping propulsion unit and controller are crossed, pressing unit, transmission mechanism and clamping are passed through
Mutual cooperation between propulsion unit, on the one hand, upper and lower two clamping pieces can carry out clamping position to plate, so as to avoid gold
The offset for belonging to bending position on tubing, improves the qualification rate of product；On the other hand, in the driving and biography for passing through clockwise and anticlockwise motor
The transmission of motivation structure, so that clamping piece and pressing plate are drawn close to centre simultaneously, thus by metal pipe material bending clamped by clamping piece,
By the common cooperation of clamping piece and pressing plate, the stroke that pressing plate needs clockwise and anticlockwise motor to push shortens, to greatly improve life
The speed of production.
Firstly, metal pipe material is placed among two clamping pieces, clockwise and anticlockwise motor is driven by controller, when driving electricity
