Description

Technical Field

[0001] This utility model discloses a circular knife device, belonging to the field of pipe cutting machine technology, specifically relating to a circular knife device for a pipe cutting machine. Background Technology

[0002] A pipe cutter is a common pipe processing device primarily used for quickly and accurately cutting pipes. Using a pipe cutter can significantly improve work efficiency, reduce the difficulty and fatigue of manual operation, and simultaneously improve the precision and quality of pipe cutting. Therefore, pipe cutters are widely used in construction, manufacturing, pipe installation, and maintenance.

[0003] There are various types of pipe cutting machines, each with its specific cutting method and applicable range. Common pipe cutting machines include manual pipe cutting machines, electric pipe cutting machines, and CNC pipe cutting machines. Manual pipe cutting machines are generally suitable for smaller pipe diameters and have lower cutting efficiency; electric pipe cutting machines have higher working efficiency and precision; while CNC pipe cutting machines can achieve high-precision, high-speed, and automated cutting.

[0004] Traditional manual pipe cutters are inefficient, while automatic pipe cutters require manual movement. Furthermore, when changing the cutter, the traditional method requires disassembling the cutter mechanism, which is very troublesome. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] A pipe cutting machine circular blade device includes: a transverse movement mechanism 1, a pneumatic actuator 2, and a cutter 3.

[0024] In one embodiment, such as Figure 1 As shown, the transverse movement mechanism 1 is mounted on the workbench; the pneumatic actuator 2 is mounted on the transverse movement mechanism 1; and the cutting rotation mechanism is mounted on the pneumatic actuator 2.

[0025] In one embodiment, such as Figures 2 to 3As shown, the transverse movement mechanism 1 includes: a base 10, fixedly mounted on a workbench; a motor base 11, fixedly mounted on one side of the base 10; a drive motor 12, fixedly mounted on the motor base 11; two first guide rails 13, fixedly mounted inside the base 10; a lead screw 14, rotatably mounted on both ends of the base 10 via bearing seats and located between the first guide rails 13; a linear bearing 15, mounted on the lead screw 14; a coupling 16, one end connected to the rotating shaft of the motor and the other end connected to one end of the lead screw 14; a first slider 17, slidably mounted on the first guide rail 13; and a connecting plate 18, fixedly mounted on the first slider 17 and fixedly connected to the linear bearing 15.

[0026] In one embodiment, such as Figure 4 As shown, the pneumatic actuator 2 includes: a bracket 20, fixedly mounted on the connecting plate 18; a second guide rail 21, fixedly mounted on the connecting plate 18; a second slider 22, slidably mounted on the second guide rail 21; a cylinder 23, fixedly mounted on one side of the bracket 20; a tool holder 24, fixedly mounted on the second slider 22; and an interface 25, one end of which is fixedly connected to the end of the telescopic rod of the cylinder 23, and the other end of which is connected to the tool holder 24.

[0029] Working principle: When this utility model is in operation, the cutter 3 is first installed on the cutter holder 24, and then the transverse mechanism 1 works. The first motor rotates, which drives the lead screw 14 to rotate through the coupling 16, thereby driving the linear bearing 15 to move on the lead screw 14, thereby driving the connecting plate 18 to move through the first guide rail 13 and the first slider 17, thereby actuating the pneumatic actuator 2 to move. When it moves to the designated position, the pneumatic actuator 2 works, the first cylinder 23 works, and drives the cutter holder 24 to move through the interface 25 through the second guide rail 21 and the second slider 22, thereby realizing the work. When the cutter needs to be replaced, simply loosen the interface 25 to replace it.
