According to the aviation pipe cyclone cutting device provided by the invention, the cyclone cutting method is also provided, and the feeding and retracting of the cutter can be controlled better, so that the aviation pipe can be cut, and specifically, the operation mode is as follows:
the cyclone cutting method for the aviation pipe comprises the following steps:
A. workpiece alignment, namely placing a pipe to be cut on a support pipe wheel 2 through a mechanical arm 3, and aligning the center of the pipe to the center of a cutting head 1 by lifting or lowering the support pipe wheel 2 according to different pipe diameters;
B. feeding: after the workpiece is aligned, conveying the pipe material to be cut to the corresponding position of the cutting head 1 and clamping;
C. performing cyclone cutting: the feeding motor 12 and the main motor 5 are respectively started, the main motor 5 drives the driving belt wheel to drive the whole body to rotate, and then the feeding servo motor drives the feeding spiral turntable 11 through the feeding driving wheel to form a speed difference with the shell to realize cutter feeding, and the pipe cutting is completed.
The main motor 5 and the feeding motor 12 implement a certain rotation proportion according to the proportion of the spiral rotary table 11 and the cutter head 6, so that the instantaneous speeds of the spiral rotary table 11 and the cutter head 6 are kept consistent.
In the step C, when cutting feed is needed, the feeding motor 12 is accelerated, so that the rotation of the spiral turntable 11 is faster than that of the cutterhead 6; conversely, when the cutter is required to retract, the speed of the speed reducing feed motor 12 is lower than that of the cutter head 6 by the rotating speed of the spiral rotary table 11.
In the step C, a speed curve of the motor to be operated is planned according to the size of the pipe fitting, then the speed curve is discretized, data are segmented every 125us, and the motion controller outputs the speed according to the time interval of every 125us, so that the output is consistent with the planned curve.
Specifically, for example, for an aluminum alloy part aviation pipe produced on an existing production line, a raw material pipe produced in a previous rolling process is generally 3-6m long, and the raw material pipe needs to be cut into a plurality of sections according to requirements.
The cyclone cutting device provided by the invention adopts the following steps:
main motor 5: the power is 3kw;
a feed motor 12:0.75kw;
and are all alternating current servo motors, wherein the main motor 5 drives the cutter disc 6 and the spiral turntable 11 to rotate at the same speed, and the feed motor 12 drives the spiral turntable 11 to rotate, so that a speed difference is generated between the spiral turntable 11 and the cutter disc 6. Thus, the cutting blade 10 can be advanced and retracted when the screw turntable 11 drives the cutter to move again during rotation.
The rotation speed of the main motor 5 can be changed according to the diameters of different raw material pipes by a control system. The ratio of the rotation speed of the main motor 5 to the rotation speed of the feed motor 12 is: 1:4, namely 1 rotation of the main motor 5, 4 rotations of the feeding motor 12, 750r/min of the maximum rotation speed of the main motor 5 and 3000r/min of the maximum rotation speed of the feeding motor 12, wherein the instantaneous speed (comprising acceleration and deceleration processes) of the main motor 5 and the feeding motor 12 always maintains a relation of 1:4, so that the cutter does not have feeding motion, when the speed of the main motor 5 is higher than that of the feeding motor 12, the cutter moves in a retracting manner, and when the speed of the feeding motor 12 is higher than that of the main motor 5, the cutter moves in a feeding manner.
For example: when the main motor 5 and the feeding motor 12 are started from zero at the same time, the speed ratio is always kept 1:4, when the speed of the main motor 5 reaches 600r/min, the speed of the feeding motor 12 is 2400r/min, if cutting is to be performed by feeding, the speed of the main motor 5 is kept unchanged, the speed of the feeding motor 12 is larger than 2400r/min, and after cutting is completed, the speed of the main motor 5 is kept unchanged, and the retracting can be realized by only reducing the speed of the feeding motor 12 to be lower than 2400 r/min; for the feed motor 12 to run 10 revolutions alone, the screw turntable 11 rotates 1 revolution, the tool is fed 16mm, that is to say the tool is fed or withdrawn 1.6mm for each 1 revolution of the feed motor 12 relative to the main motor 5.
In summary, the invention adopts the mode that the cutter rotates and the workpiece is fixed, a plurality of cutting cutters are driven to rotate respectively by two driving sources from different directions through a good design, and the speed difference is formed, so that the cutter feeding and the cutter retracting are respectively realized, the cutting is directly carried out from a multi-direction angle, the cutting mode is faster, and the cutting effect is obviously better than that of the traditional cutting mode.
The above embodiments are merely for illustrating the technical solution of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the corresponding technical solutions.
