Abstract

(57) [Summary] [Purpose] It is intended to provide an automatic copper pipe cutting machine capable of cutting pipes automatically without using human hands. [Structure] The rotor is supported by bearings on both sides, and is rotated by a sprocket attached to the rotor. The rotor has a hole extending axially therethrough so that a copper pipe can pass therethrough. A cutter and a guide roller are provided in the middle of the rotor and rotate together with the rotor. A bearing that moves parallel to the rotor is provided on the outer circumference of the rotor, and the inside of the bearing is a rotating body and the outside of the bearing is a non-rotating body. The rotating body is rotated by a slide key attached to the rotor, and moves in parallel according to the rotation of the rotor.The rotating body has a taper liner that pushes the cutter around the shaft, and the guide roller can adjust the pipe diameter according to the pipe diameter. A liner is provided. The moving bearing is configured to move in parallel by being pushed by the bearing of the ball screw.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a copper pipe cutting machine for easily cutting a copper pipe or the like having an arbitrary diameter.

[0002]

[Prior Art]

 In the conventional cutting, the length was measured with a scale, the roller cutter and the roller were manually fixed to the outer diameter of the copper pipe, and the cutting was done by rotating it manually.

[0003]

[Problems to be solved by the device]

 However, in the above method, the length is measured on a scale each time, and the cutting work is done by human hands, which consumes a great deal of time. The present invention has been made in view of the above problems, and an object of the present invention is to provide an automatic copper pipe cutting machine which can automatically cut a pipe without using human hands.

[0004]

[Means for Solving the Problems]

 According to the present invention, a rotor is supported by bearings on both sides and is rotated by a sprocket attached to the rotor. The rotor has a hole in the center through which the copper pipe can pass. A cutter and a guide roller are provided in the middle of the rotor and rotate together with the rotor. A bearing that moves parallel to the rotor is provided on the outer circumference of the rotor, and the inside of the bearing is a rotating body and the outside of the bearing is a non-rotating body. The rotating body is rotated by a slide key attached to the rotor, and moves in parallel according to the rotation of the rotor. The rotating body is equipped with a taper liner that pushes the cutter around the shaft, and the guide roller is equipped with a pipe diameter adjustment liner that can be adjusted according to the pipe diameter. The moving bearing is configured to move in parallel by being pushed by the bearing of the ball screw.

[0005]

[Action]

 Since the present invention has the above-mentioned means, when this is used, the copper pipe is first inserted into the through hole of the rotor to the required length. After that, the rotor is rotated through the sprocket, the moving bearing is moved in parallel, and the cutter cuts the copper pipe into a required length.

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2. (1) is a cylindrical rotor provided with a sprocket (5). (2) is composed of a cutter case (2) a containing a roller cutter (2) a1 and a roller (2) b that follows the upper surface of the taper liner (6). (3) is a guide roller, and is composed of a roller case (3) a containing the roller (3) a1 and a roller (3) b rolling on the upper surface of the pipe diameter adjusting liner (7). A moving bearing (4) is composed of a rotating body (4) a and a non-rotating body (4) b. The rotating body (4) a includes a taper liner (6) and a pipe diameter adjusting liner (7) that moves up and down depending on the pipe diameter. The rotating body (4) a is rotated by a slide key (8) provided on the rotor (1). The non-rotating body (4) b is translated by the ball screw (9).

An example of using the copper pipe automatic cutting machine configured as described above will be described below. First, the copper pipe A is inserted into the through hole of the rotor (1) with a required length. After that, the rotor (1) is rotated through the sprocket (5), and the moving bearing (4) is moved in parallel, whereby the roller (2) b is rotated along the upper surface of the taper liner (6), and the cutter (2) is rotated. ) Is pressed downward and the roller cutter (2) a1 cuts into the circumference of the copper pipe A and cuts the copper pipe A to a required length.

The control method for feeding the copper pipe and setting the dimensions in the above embodiment may be arbitrarily selected. Further, the cutting is not limited to the copper pipe, but can be applied to an aluminum pipe or the like.

[0009]

[Effect of the device]

 As described above, the present invention has the following effects. It has the effect of cutting copper pipes easily and reliably and automatically.
