Technical field
The present invention relates to metal works processing technique field, in particular to a kind of processing unit (plant) of large-size pipe.
Background technique
Currently, large-size pipe when carrying out cutting operation, due to being relatively large in diameter for pipe fitting, not directly cuts off, spends money week
Folding, currently, the use of more scheme being that drive cutting mechanism using translational drive mechanism flat to carry out perpendicular to the axial direction of pipe fitting
It moves, with property cut pipe fitting, but the disadvantages of this solution is it is obvious that be exactly to be easy to drive pipe fitting to generate during cutting off pipe fitting
Axial dipole field influences the cutting dimensional accuracy of pipe fitting.
Summary of the invention
The object of the present invention is to provide a kind of processing unit (plant)s of metal works, it is ensured that the cutting dimensional accuracy of pipe fitting, and

Compared with prior art, the beneficial effects of the present invention are one, it is ensured that the cutting size of pipe fitting, and grasp
Facilitate, when cutting off pipe fitting, drives main slide to move to tube intracavity direction using level-one drive cylinder, so that main protrudes into
Seat can extend into the inner cavity of pipe fitting, so that ring cutting executing agency is in the inner cavity of pipe fitting, at this point, using oil of retreating
Cylinder drives ring cutting driving motor to be slided smoothly intracavitary, so that ring cutting drive shaft is stretched out, ring cutting drive shaft can be driven
Ring cutting executing agency to scheduled position, therefore, under the twin-stage regulation of level-one drive cylinder, advance and retreat oil cylinder, ring cutting executes machine
Structure can accurately be sent to scheduled off-position, then under the control of ring cutting driving motor, ring cutting drive shaft pivoting, from
And ring cutting executing agency is driven to be rotated around the axis of ring cutting drive shaft, due to the axis of ring cutting drive shaft and the axis of pipe fitting
Line coincides, so, ring cutting executing agency can cut off pipe fitting when rotated;Second, the pipe fitting cutting of different inner diameters can be met
Operation, when front pole-bracket protrudes into tube intracavity, all rangefinders measure under the control of PLC controller, if all surveys
The measurement error of distance meter within the allowable range, it means that the misalignment of axe of the axis of ring cutting drive shaft and pipe fitting permit
Perhaps in range, ring cutting executing agency cutting pipe fitting, such ring cutting executing agency anti-work suffered when being rotated can just be started
It is firmly that uniformly, the radial load fluctuation of ring cutting drive shaft is little, if it find that the axis of the axis of ring cutting drive shaft and pipe fitting
Line deviation transfinites, then, it can adjust the position of pipe fitting, or adjustment main protrudes into the height and position of seat, and supports before suitably adjusting
The height and position of return pulley and auxiliary support wheel, so that preceding support return pulley and auxiliary support wheel contradict pipe fitting internal perisporium always, with fine
Offset the vibration that ring cutting executing agency generates when rotated in ground.
As a further improvement of the present invention, the ring cutting executing agency includes ring cutting foundation frame, the ring cutting foundation frame

The dynamic radial expansion seat being sleeved on ring cutting foundation frame, further include can drive radial expansion seat carry out telescopic movable, controlled by PLC
The pressing electric pushrod of device processed control, one end opposite with pipe fitting internal perisporium is rotatably mounted with limit on the radial expansion seat
Position contradicts wheel, is equipped with the cutting motor controlled by PLC controller, the output master of the cutting motor on the radial expansion seat
The cutting blade for cutting off pipe fitting is set on axis, when cutting blade cuts through pipe fitting just, the limit contradicts wheel periphery
Lucky face and the internal perisporium for contradicting pipe fitting.When carrying out cutting operation to pipe fitting, pressing electric pushrod drives radial expansion seat
It stretches out, meanwhile, cutting motor drives cutting blade to carry out high speed rotation with cutting pipes, cuts through pipe fitting just in cutting blade
When, limit contradicts wheel periphery and contradicts the internal perisporium of pipe fitting just, it is possible to start ring cutting driving motor, so that ring cutting drives
Moving axis, ring cutting executing agency are rotated to completely cut through pipe fitting, and in the process, limit contradicts wheel and plays position-limiting action,
The vibration that not only can suitably offset cutting blade generation, can also play good guiding role, so that ring cutting executing agency
It can smoothly be rotated in cutting.
As a further improvement of the present invention, the foundation base is equipped with limit sliding chutes, and the main slide is movably arranged on
In limit sliding chutes, the main slide is equipped with the limit inductor that a pair is arranged in main two opposite side of slide, the limit
Inductor is connected with PLC controller, and when cutting off pipe fitting, the induction end of one of limit inductor corresponds in position just
The side of limit sliding chutes, when preceding support return pulley, auxiliary support wheel are on the position of datum plane, another limit inductor
Induction end correspond to the other sides of limit sliding chutes in position just.When cutting off pipe fitting, the sense of one of limit inductor
The side for corresponding to limit sliding chutes in position just should be held, illustrates that main slide has moved to reasonable off-position, in preceding support
When return pulley, auxiliary support wheel are on the position of datum plane, ring cutting executing agency has been moved off the inner cavity of pipe fitting, illustrates to lead
Slide has moved to another extreme position, and two limit inductors can limit the motion range of main slide, preferably to control
Cutting process process processed.
As a further improvement of the present invention, the translation conveyors structure includes chassis, further includes multiple along pipe fitting
Translation direction is arranged in a straight line, the horizontally disposed, conveying roller that is pivotally mounted on chassis, further include it is multiple with it is defeated
