Description

Technical Field

[0001] This utility model relates to the field of machining machinery technology, and in particular to a sealing strip cutting device. Background Technology

[0002] Existing cutting devices cannot precisely machine the cutting surface with cylindrical grooves, resulting in insufficient geometric accuracy at the sealing ring connection. This defect directly compromises the integrity and fit of the sealing surface, creating microscopic leakage channels. Traditional equipment lacks angle adjustment capabilities, making it difficult to meet the cutting requirements of different connection angles. This limitation leads to poor matching of the connection cross-section, resulting in stress concentration and gaps. Gaps caused by machining defects in the rubber sealing ring significantly reduce the sealing effect, while end face wear and improper installation are the main causes of leakage, and insufficient cutting surface precision exacerbates these problems. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0018] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0019] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0021] like Figures 1-12 As shown, this utility model proposes a sealing strip cutting device, including a positioning box 1 and a cutting tool 5. The positioning box 1 has a tool through hole 2 for the cutting tool 5 to pass through and a workpiece through hole 3 for the sealing strip 8 to pass through. The tool through hole 2 and the workpiece through hole 3 intersect and form an included angle between them. The length of the cutting tool is not less than the length of the tool through hole 2. The number of tool through holes 2 and workpiece through holes 3 can be set as needed.

[0022] Furthermore, both the tool through hole 2 and the workpiece through hole 3 are provided with an enlarged section 4 at their ends. The diameter of the enlarged section 4 is larger than the diameter of the tool through hole 2 and the workpiece through hole 3, so as to facilitate the insertion of the sealing strip 8 and the cutting tool 5.

[0023] Preferably, the cutting tool 5 includes a fixed cutting edge and a handle. The end of the handle furthest from the cutting edge has an enlarged portion 6, larger than the tool through-hole 2. A limiting flange 7 is provided on the side of the handle. The limiting flange 7 limits the position of the cutting edge within the tool through-hole 2, thereby preventing the cutting edge from exiting the tool through-hole 2 and damaging the worktable. The enlarged portion 6 allows for easy application of force by the palm, thus facilitating operator use.

[0024] Preferably, the cutting edge is an arc-shaped structure matching the outer diameter of the cylindrical sealing strip 8, and the radius of curvature of the cutting edge is consistent with the outer diameter of the sealing strip 8, so that the cutting surface of the cylindrical groove is completely fitted with the original cylindrical outer surface without gaps, thereby improving the tightness of the sealing connection.

[0025] Preferably, the cutting edge of the cutting edge has a concave profile. When the sealing strip 8 passes through the square box, the tool rotates or translates to cut, forming a cylindrical groove cutting surface on the surface of the sealing strip 8 that fits against the original cylindrical outer surface.

[0026] Preferably, such as Figures 2-9 As shown, the included angle is 90°, 30° or 45°, and other angles can also be set as needed.

[0027] Preferably, the positioning box 1 is rectangular in shape to facilitate manufacturing and use.

[0028] Preferably, the surface of the positioning box 1 is provided with a scale to facilitate rotation of the cutting angle.

[0029] Preferably, the positioning box 1 is made of metal, such as steel, aluminum alloy, or stainless steel, as needed.

[0030] In use, the cylindrical sealing strip 8 is inserted into the workpiece through hole 3 on one side of the positioning box 1 and exits from the other side. The target angle to be cut is selected, and the cutting tool 5 is inserted into the corresponding tool through hole 2. The cutting tool 5 is manually pressed down, and while the sealing strip 8 passes through the positioning box 1 at a uniform speed, the cutting tool 5 cuts its surface, forming a cutting surface with a cylindrical groove. This groove can tightly fit the outer surface of another cylindrical sealing strip, creating a tooling cut 9. Figures 10-12 As shown.

[0031] This invention relates to a sealing strip cutting device. Positioning is achieved through a box with both a tool through-hole 2 and a workpiece through-hole 3. The resulting cylindrical groove cutting surface completely fits the original cylindrical outer surface without gaps, improving the tightness of the sealing connection. This solves the technical problem of existing rubber sealing ring cutting devices being unable to process cylindrical groove cutting surfaces, leading to gaps during sealing ring connection and affecting the sealing effect. By setting different included angles, this invention can achieve cylindrical sealing ring connection section cutting at various angles, meeting connection requirements under different working conditions (such as pipe intersections, non-uniform connections, etc.). Furthermore, the device has a simple and efficient structure, is easy to manufacture, and reduces the difficulty of manual operation.

[0032] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
