[0023] The working principle of the pipe profiling blanking device is as follows:
[0024] 1. Tensioning and positioning stage
[0025] Inner wall self-adaptive fixation: the tensioning and supporting mechanism 1 drives the up / down tensioning blocks (1-1 / 1-2) and the left / right tensioning blocks (1-3 / 1-4) to move radially through the adjustment screw 1-6, and cooperates with the elastic deformation of the rubber pad 1-7, so that the device is stably clamped on the inner wall of the pipe.
[0026] Axial limiting compensation: the telescopic extension rod 1-8 is extended to the pipe end face according to the length of the pipe, so as to ensure the axial positioning accuracy of the device.
[0027] 2. Profiling trajectory setting stage
[0028] Angle disc synchronous driving: the operator rotates the profiling force applying rod 5 to drive the angle profiling disc 4 to synchronously rotate the angle disc 3 to the set angle, or directly rotates the angle profiling disc, and the angle disc scale indicates the cutting starting angle.
[0029] Contour matching: The first slider 6 slides radially along the edge of the contouring disc 4 and is locked in position by fastening bolts 6-4, so that the swing amplitude of the contouring force bar 5 matches the contour of the contouring disc.
[0030] 3. Segmentation Execution Phase
[0031] Linkage transmission mechanism: When the contouring force rod 5 rotates around its circumference, it drives the contouring rod to swing through the first connecting piece 8, which in turn drives the cutting tool 11 to move along the preset trajectory of the contouring disk.
[0032] Dynamic fit control:
[0033] Radial Adaptation: The contour rod limiting member 12, through the elastic force of the elastic member 14, pushes the limiting post 13 to always press against the inner wall of the pipe, eliminating radial displacement caused by cutting vibration. At the same time, when the contour rod is at the lowest point, the limiting post on the limiting member prevents the contour rod from detaching from the pipe.
[0034] Axial following: When the two side support arms 10-2 of the cutting tool fixing seat 10 swing with the contour rod, the elastic component 14 extends and retracts synchronously to ensure that the vertical feed of the cutting tool 11 matches the curvature of the pipe.
[0035] 4. Error Elimination Mechanism
[0036] Multi-level limit design:
[0037] The fastening structure of the L-shaped slider 6: the horizontal part 6-1 fits against the plane of the contour plate (4) to prevent axial movement when the contour force rod 5 swings.
[0038] Angle adjustment of hinge seat 8-2: The first connecting piece 8's contour rod hinge seat 8-2 allows for multi-angle fine adjustment of the contour rod to compensate for pipe ellipticity error.
[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
