    Description BE2020 / 5016 Built-in device for cutting irregular sections for large pipelines Technical area The invention belongs to the technical field of mechanical production engineering and relates to a built-in device for cutting irregular sections for large pipelines and is used for the contactless cutting of irregular sections or any curved surfaces for the large pipelines.
    Background Technology With the development of economy and technology, large diameter pipelines are required for long-distance transportation of oil, natural gas and water. When laying the pipeline, it is essential to cut and weld the pipeline in order to realize the flat butt joint, the right angle butt joint and the oblique butt joint of the pipe.
    In the prior art, for the cut-and-butt joint portion of a large-diameter pipeline, the clamp-type external pipe cutter is often used, but only a flat butt joint can be released while the right-angle butt joint can only be made by hand. Manual marking is adopted first, and then manual grinding wheel is used for cutting and welding. In this way, the cut pipe section has large losses and poor precision, which cannot guarantee the quality of the butt joint.
    As a non-contact thermal processing method, laser cutting can cut almost all materials and the cutting path is not limited. The two-dimensional section cutting or the three-dimensional section cutting can be realized. Laser cutting offers the advantages of high processing accuracy, high cutting speed, smooth incision, material savings and low processing costs. There is no contact between the mechanical part of the laser cutting head and the workpiece.
    There is no cutting resistance and no special clamping during the work process, which is economical and time-saving.
    For a long time, the DC motor speed control system has always dominated the high performance requirements of the high speed control, but there are some inherent disadvantages of the DC motor, such as the brush and commutator, which wear out easily and require frequent maintenance.
    If the commutator changes direction, sparks are generated, the maximum speed of the motor and the application environment was limited.
    In addition, the structure of the DC motor is complicated, it is difficult to manufacture, the consumption of steel materials used is high, and the manufacturing cost is high.
    With the same volume, the output power of the AC motor can be increased by 10% - 70% compared to the DC motor.
    In addition, the capacity of the AC motor can be larger than that of the DC motor to achieve higher voltage and speed.
    Modern CNC machine tools tend to use an AC servo drive, which shows the trend that the AC servo drive has replaced the DC servo drive.
    In order to solve the problem of cutting an irregular inclined section or a special intersecting curved surface on any part of the pipeline during the process of a right angle butt joint or an oblique butt joint of the large pipe, a built-in device for cutting irregular portions for the large pipe is used developed, which adopts AC servo drive technology and laser cutting and welding technology to realize the automatic control and setting of the cutting track.

    Specific Embodiment The invention is described in detail below in combination with the accompanying figures: As shown in Fig. 1, a built-in device for cutting irregular sections for the large pipelines comprises a support frame component, a translation component, a rotation component and a telescopic compensation component.
    The support frame component comprises three telescopic components with the same structure that can be moved in a straight line.
    The three telescope components are distributed in a herringbone shape at the same angle in the triangular position of the herringbone support frame component.
    The three telescope components are firmly connected to one another by the support base 6.
    The translational component is coaxially connected to the rotational component.
    The rotational component is firmly connected to the end of the horizontal screw 4 in the translational component.
    The axis of the rotational component is perpendicular to the axis of the telescope compensation component.

    Rotary motor rotor 16 connected. 3E2020 / s016 As shown in Fig. 2, the support frame component consists of a support base 6, a motor base 7, a support motor stator 8, a support motor rotor 9, a screw sleeve 10, a flat guide wedge 11, a support screw rod 12 and a fixed spiral 13. The support motor stator $ is firmly connected to the support base 6.
    The screw sleeve 10 is firmly installed in the center of the support motor rotor 9.
    The screw sleeve 10 is screwed onto the support screw rod 12.
    A flat wedge 11 is arranged on the support screw rod 12.
    The end of the support screw rod 12 is provided with a locking roller 13.
    The support screw rod 12, the screw sleeve 10, the support motor rotor 9 and the support motor stator 8 are installed coaxially.
    The support base 6 and the motor base 7 have an inner cavity in the axial direction of the support screw rod 12, via which the support screw rod 12 can enter the support base 6.
    In the inner hole of the support motor end cover 32, a keyway for through-hole that mates with the guide flats 11 is disposed.
    Three support motors adopt the same type of AC servo motor.
    Working method of the present invention: In the built-in jig for cutting irregular sections for the large-diameter pipelines, insert the device into the Robr pipe, start the three support servomotors of the support frame component, rotate the support screw rod 12 on the inner wall of the pipeline 1, and lock and fix with the locking roller 13, use the locking roller 13 to lock and fix and then start the compensating motor in the telescopic compensating component.

    Under the limitation and guidance of the horizontal guide rod 5, it drives the rotation component and the telescopic compensation component in order to realize the shift to the left and right. Start the rotating component of the rotating component, rotate the motor rotor 15, drive the compensating motor, screw rod and laser cutting head 18 to rotate axially, at the same time open the laser cutting head 18, cut the pipeline, and rotate the device for a circle, then a complete irregular section or curved surface can be cut.
    Functional principle of the present invention: With the built-in device for cutting irregular sections for the large rough lines, the frame is supported by the direct connection and direct drive of the servo motor and screw nut mechanism. The adjustment of the servo motor makes the support spacing vanabel. The translation motor rotor drives the horizontal screw sleeve to rotate so that the horizontal screw moves horizontally. Adjust the horizontal reciprocating motion of the laser cutting head to realize the cutting of irregular sections or arbitrarily curved cut surfaces. The rotary motor rotor drives the motor to rotate in order to realize the indexable cutting movement of the laser cutting head. The dynamic adjustment between the self-balancing center of rotation and the laser head and the inner wall of the pipeline can be realized by the coaxial fixed connection of the forwards and backwards screw nut pairs and the infrared distance measurement in order to adapt to the different shapes of different shapes of pipeline sections. The direct connection and direct drive of the balance motor and the forward and backward screw nut pairs is used to realize a closed loop control of the setting process to avoid the troublesome setting and positioning of the cutting machine in advance.
