Description

Technical Field

[0001] This utility model relates to the technical field of non-magnetic pipe cutting devices, and in particular to a non-magnetic pipe cutting device with a protective mechanism. Background Technology

[0002] A non-magnetic pipe cutting device is a specialized piece of equipment designed for cutting pipes made of non-magnetic materials. The core requirement for this type of equipment is that it does not introduce any magnetism during the cutting process.

[0003] Most existing non-magnetic pipe cutting devices are equipped with protective covers for protection. However, the existing protective covers are usually of fixed size or require manual adjustment, making it difficult to form a tight and dynamic seal with the outer wall of pipes of different diameters. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a non-magnetic pipe cutting device with a protective mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A non-magnetic pipe cutting device with a protective mechanism includes a cutting device body, the cutting device body includes a cutting unit, the cutting unit includes a protective cover, an auxiliary protective component is sleeved on the outside of the protective cover, and the auxiliary protective component is connected to the protective cover through an installation component.

[0007] The auxiliary protection component includes a mounting frame. The bottom of the mounting frame is connected to a telescopic protection component via a fastening component. The telescopic protection component includes a telescopic protective cover. An installation ring is fixedly sleeved on the outer wall of one end of the telescopic protective cover. Multiple extension protrusions are installed on the outer wall of the other end of the telescopic protective cover. A positioning rod is installed on the extension protrusion, and one end of the positioning rod passes through the mounting ring and is screwed to a limit member. A spring body is sleeved between the extension protrusion and the mounting ring and outside the positioning rod.

[0008] In addition, in a preferred configuration, an extension frame is fixedly fitted onto the outer wall of one end of the mounting frame, and positioning holes are provided in both the extension frame and the mounting ring at the positioning rod, and multiple mounting holes are provided in both the extension frame and the mounting ring.

[0009] Furthermore, in a preferred configuration, the outer wall of the positioning rod away from the extending protrusion is provided with an external thread, and the limiting member is provided with an internal thread that mates with the external thread of the positioning rod.

[0010] Furthermore, in a preferred configuration, the mounting assembly includes a mounting base, one side of which is fixedly connected to the protective cover, and the other side of which is screwed with a fastener. An auxiliary hole is provided in the mounting frame at the fastener location.

[0011] Furthermore, in a preferred configuration, the bottom of the extended protrusion is provided with a movable groove, and a ball bearing is movably embedded in the movable groove.

[0012] In addition, in a preferred configuration, the cutting unit further includes a cutting disc, which is driven by a drive unit. The protective cover is located outside the cutting disc, and an clearance groove is provided in the mounting frame at the drive unit.

[0013] In addition, a preferred structure is that the two ends of the spring body are respectively connected to the corresponding extension protrusion and extension frame.

[0014] The beneficial effects of this utility model are as follows:

[0015] In this invention, a protective cover provides basic protection. At the same time, the extension protrusion driven by the spring body continuously pushes one end of the telescopic protective cover to fit against the outer wall of the non-magnetic pipe to be cut. This facilitates active and dynamic fitting against the outer wall of pipes of different diameters within a certain range, ensuring that the cutting device body can shield the rapidly rotating cutting disc or splashing pipe debris during the cutting process.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A non-magnetic pipe cutting device with a protective mechanism includes a cutting device body 1, a cutting unit 2, a protective cover 21, an auxiliary protective component 3 on the outside of the protective cover 21, and the auxiliary protective component 3 connected to the protective cover 21 through a mounting component 38.

[0024] Meanwhile, the auxiliary protective component 3 includes a mounting frame 31. The bottom of the mounting frame 31 is connected to a telescopic protective component via a fastening component. The telescopic protective component includes a telescopic protective cover 32. A mounting ring 33 is fixedly sleeved on the outer wall of one end of the telescopic protective cover 32. Multiple extension protrusions 34 are installed on the outer wall of the other end of the telescopic protective cover 32. A positioning rod 35 is installed on the extension protrusion 34, and one end of the positioning rod 35 passes through the mounting ring 33 and is screwed to a limiting member 37. A spring body 36 is sleeved between the extension protrusion 34 and the mounting ring 33 and outside the positioning rod 35. The two ends of the spring body 36 are respectively connected to the corresponding extension protrusion 34 and the extension frame.

[0025] Furthermore, an extension frame is fixedly fitted on the outer wall of one end of the mounting frame 31, and positioning holes are opened in both the extension frame and the mounting ring 33 at the positioning rod 35. Multiple mounting holes are also opened in both the extension frame and the mounting ring 33. It is worth noting that the positioning holes of the extension frame and the mounting ring 33 are coaxial.

[0026] Furthermore, the outer wall of the positioning rod 35 away from the extension protrusion 34 is provided with an external thread, and the limiting member 37 is provided with an internal thread that mates with the external thread of the positioning rod 35.

[0027] Meanwhile, the mounting component 38 includes a mounting base, one side of which is fixedly connected to the protective cover 21, and the other side of the mounting base is screwed with a fastener. An auxiliary hole is provided in the mounting frame 31 at the fastener location. The fastener of the mounting base requires a high-strength bolt and an elastic washer.

[0028] Meanwhile, the bottom of the extended protrusion 34 is provided with a movable groove, and a ball bearing 39 is movably embedded in the movable groove.

[0029] Furthermore, the cutting unit 2 also includes a cutting disc, which is driven by a drive unit. The protective cover 21 is located outside the cutting disc, and a clearance groove is provided in the mounting frame 31 at the drive unit. It is worth noting that the specific structure, connection method, and working principle of the cutting unit 2 and the cutting device body 1 are all existing technologies already disclosed in the market, so they will not be described in detail. At the same time, the cutting device body 1 is a pipe cutting device made of non-magnetic material.

[0030] Furthermore, it is worth mentioning that the pleated structure of the telescopic protective cover 32 must avoid the extension protrusion 34 and the positioning rod 35. The aforementioned positioning rod, spring body, ball bearings, etc. are all made of non-magnetic materials, and the ball bearings 39 and the positioning rod 35 are coated with a diamond coating.

[0031] In this embodiment, basic protection is provided by the protective cover 21, and the external retractable auxiliary protective component 3 forms a second physical barrier to shield the rapidly rotating cutting disc or splashing pipe debris.

[0032] Driven by the spring body 36, the extended protrusion 34 continuously pushes one end of the telescopic protective cover 32 to adhere to the outer wall of the non-magnetic pipe to be cut, which facilitates active and dynamic adhesion to the outer wall of pipes of different diameters within a certain range, ensuring that the metal debris generated by the cutting device body 1 during the cutting process is confined within the closed or semi-closed space formed by the protective cover 21 and the telescopic protective cover 32.

[0033] Among them, the diamond-coated ball 39 at the bottom of the extended protrusion 34 converts friction into rolling friction, avoiding damage to the surface of the non-magnetic tubing.

[0034] In this utility model, the protective cover 21 provides basic protection. At the same time, the extension protrusion 34 driven by the spring body 36 continuously pushes one end of the telescopic protective cover 32 to adhere to the outer wall of the non-magnetic pipe to be cut, so as to actively and dynamically adhere to the outer wall of pipes of different diameters within a certain range, ensuring that the cutting device body 1 shields the rapidly rotating cutting disc or the splashing pipe debris during the cutting process.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
