Description

[0001] PIPE CUTTING DEVICE [0002]

The present invention relates to a pipe cutting apparatus using centrifugal force according to rotation,

The rotating body rotates by the rotating device and the cutting plate including the cutting tool attached to the rotating body is moved in the direction opposite to the center of rotation according to the centrifugal force so that the cutting tool attached to the cutting plate rotates the centrifugal force To a cutting device that cuts while being rotated along a circumferential surface of a workpiece to be cut.

With regard to the cutting technology of pipes and piping,

In the case of a device for cutting a small pipe or pipe,

In order to apply the force in the direction of the center of the workpiece while fixing the workpiece and rotating the cutting tool, the cutting tool attached to the tip of the ballscrew structure is moved by the pitch of the thread by manual or motor force, In case of manual operation, there is a problem that a constant force is applied. In the structure using a motor, the cost of the product increases due to the complicated structure.

In the technique of Korean Patent Publication No. 10-1407328, the method of cutting the workpiece using the centrifugal force is the same, but in order to obtain the centrifugal force in the construction of the cutting device, the weight must be increased. .

In the case of a large pipe or pipe cutting apparatus,

A cutting apparatus configured to fix a workpiece to be cut and configured to rotate an outer periphery of a fixed pipe is integrally formed with a rotating apparatus so as to rotate the cutting tool and thereby cut a workpiece to be cut.

The present invention relates to an apparatus for cutting an object to be cut while rotating along a circumferential surface of a fixed object to be cut (pipe)

In order to cut the material to be cut, a cutting device including a cutting tool is rotated along the circumferential surface of the material to be cut in a direction of the center of the material to be cut, The present invention relates to a cutting apparatus which cuts a lost force by using a centrifugal force,

It is an object of the present invention to provide a cutting apparatus that does not affect the overall size of the apparatus even when the centrifugal force is increased by combining the cutting tool with the role of a weight for centrifugal force.

In order to solve the above problems,

A cutting tool (A1) to cut the workpiece (C);

A fixing pin A2 for rotating and fixing the cutting tool A1 and a cutting tool fixing plate A3 for restricting the axial movement of the fixing pin A2 of the cutting tool A1;

The workpiece C can be penetrated and the cutting tool A1 can be engaged with the fixing pin A2 and the cutting tool fixing plate A3 and the center of gravity can be moved to the center A cutting plate A4 designed to be positioned opposite the cutting tool A1;

The cutting device A configured to be coupled to the rotating body B2 of the rotating device B for providing the sliding movement of the cutting plate A4 in the direction of the center of rotation and the centrifugal force, So that the size of the centrifugal force can be easily changed only by changing the size of the cutting plate A4 at the same speed as in the conventional method .

The size of the centrifugal force is determined by the weight of the weight, the distance between the center of the weight and the center of rotation, and the rotation speed. As described above, the material to be cut (C) The size of the weight and the position of the center of gravity can be easily changed to the size of the cutter plate A4 without changing the size of the cutting device A as a whole, So that an efficient cutting device A can be realized.

Fig. 2 is a front view of the cutting apparatus A to which the cutting tool A1 is attached. Fig.
Fig. 3 is a sectional view of the cutting apparatus A before centrifugal force acts
Fig. 4 is a sectional view of the cutting apparatus A when centrifugal force acts

Hereinafter, the present invention will be described in more detail with reference to specific embodiments of the attached drawings. The following examples are provided to further illustrate the present invention, but the technical scope of the present invention is not limited thereto.

Looking at each configuration,

1 to 4, the centrifugal force of the cutting apparatus A according to the present invention is obtained by using the rotational force of a rotary power source motor E attached to the stationary object D.

The rotating body B2 is attached to the stationary object D and has a structure that can be rotated by receiving power by the rotating device B so that the workpiece C can pass through.

The cutting device A that is coupled to the rotating body B2 is configured to be movable only in the vertical direction by the sliding means B1 so as to be able to slide in the opposite direction of the rotation center along the centrifugal force.

The cutting apparatus A described above is combined with the cutting tool A1 for cutting the workpiece C and the fixing pin A2 so as to fix the rotation of the cutting tool and the cutting tool fixing plate A3, And is connected to the plate A4 so as to move in the direction in which the material C to be cut is present when the centrifugal force is generated.

The cut plate A4 having the above-mentioned cutter (C) through-hole is configured such that the center of gravity is located in the opposite direction to the cutting tool A1 in a state where the cutting tool A1 is attached and the centrifugal force So that the cutting tool A1 coupled to the opposite side of the cutting plate A4 is rotated simultaneously with the movement of the workpiece C to the center of the workpiece C, As shown in FIG.
