1. A method for groove cutting by a one-step groove forming device for oblique, crossing of reducing pipe fittings, the one-step groove forming device comprising:
a plurality of clamping components (1); and at least one marking component (2), wherein, the clamping components (1) are movably connected and is fixedly connected, at least one clamp (3) is arranged on the clamping component (1); the marking component (2) a probe (4) and a marking knife (5) fixed on the probe (4), one end of the probe (4) is provided with a pinhead (6), and the marking component (2) is used in concert with the plurality of damping components (1), wherein, in the first step, a primary pipe fitting (12) is clamped using the clamp (3) on one clamping component (1); in the second step, a secondary pipe fitting (13) is clamped using the clamp (3) on the other clamping component (1); in the third step, the clamping component (1) for damping the secondary pipe fitting (13) is rotated, enabling the positional relationship between the primary pipe fitting (12) and the secondary pipe fitting (13) to be that connection between the primary pipe fitting (12) and the secondary pipe fitting (13) is required; in the fourth step, the location where the clamping component (1) for clamping the primary pipe fitting (12) and the clamping component (1) for clamping the secondary pipe fitting (13) are connected is fastened, so that the two clamping components (1) are relatively fixed in position and an included angle between the two clamping components (1) is an included angle when connection between the primary pipe fitting (12) and the secondary pipe fitting (13) is required; in the fifth step, the probe (4) is attached to the outer will of the secondary pipe fitting (13) with a hand or a machine, the pinhead (6) of the probe (4) comes into contact with the outer wall of the primary pipe fitting (12), the probe (4) is parallel with an axis of the secondary pipe fitting (13), and the tip of the marking knife (5) comes into contact with the outer wall of the secondary pipe fitting (13) and is parallel with an axis of the primary pipe fitting (12); and in the sixth step, while the probe (4) is rotated around the axis of the secondary pipe fitting (13) in a radial direction, the pinhead (6) leaves a motion track on the outer wall of the primary pipe fitting (12), the tip of the marking knife (5) leaves a motion track on the outer wall of the secondary pipe fitting (13), and the motion track on the outer wall of the primary pipe fitting (12) and the motion track on the outer wall of the secondary pipe fitting (13) are the same, and an groove for oblique crossing of the primary pipe fitting (12) and the secondary pipe fitting (13) is achieved. |
