Description

Technical Field

[0001] This utility model relates to the field of pipeline construction equipment technology, and in particular to a cutting device. Background Technology

[0002] In the fields of pipeline installation and building construction, beveling pipe fittings is a fundamental task. Current technology primarily employs manual methods, where workers use a protractor to mark lines on the pipe fitting surface before hand-cuttering the cutter. This method has several drawbacks: the smooth surface of the pipe fitting makes slippage and displacement during cutting easy, compromising cutting accuracy; furthermore, manual marking and angle measurement are prone to errors, affecting the accuracy of the cutting angle. While some simple tooling and specialized cutting equipment have emerged, these devices are generally complex in structure, inconvenient to operate, and lack effective angle adjustment mechanisms, making it difficult to meet the cutting needs of pipe fittings of different specifications. Especially when batch cutting of bevels at the same angle is required, current technology struggles to guarantee consistency and efficiency, directly impacting the quality of pipeline installation and construction progress. Therefore, achieving precise and efficient beveling of pipe fitting ends is a pressing technical problem that needs to be solved. Utility Model Content

[0003] This invention provides a cutting device that can achieve precise and efficient cutting of the beveled surface at the end of a pipe fitting.

[0004] This utility model provides a cutting device, including: a support assembly, the support assembly including: a support plate for supporting pipe fittings; a positioning plate disposed on the support plate and having a positioning surface for positioning pipe fittings; a lifting assembly disposed on the support assembly for lifting and lowering in a vertical direction; a sliding assembly disposed on the lifting end of the lifting assembly; and a cutting assembly slidably connected to the sliding assembly for cutting pipe fittings on the support assembly.

[0005] In one possible implementation, the support assembly further includes a base plate, on which the support plate is rotatably mounted.

[0006] In one possible implementation, the support assembly further includes a locking element for locking the support plate and the base plate.

[0013] In one possible implementation, a cleaning blade is provided on the sleeve, and a strip-shaped cleaning opening is provided at the bottom of the cleaning blade. The saw blade passes through the strip-shaped cleaning opening, and the cleaning blade abuts against the surface of the saw blade.

[0014] The cutting device provided by this utility model, through the cooperation of a support plate and a positioning plate in the support assembly, can stably support and position the pipe fitting at an angle, avoiding the problem of pipe fitting displacement that is common in traditional cutting methods.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] The following is combined with Figure 1-4 A cutting device according to an embodiment of the present invention includes: a support assembly 1, a lifting assembly 2, a sliding assembly 3, and a cutting assembly 4, wherein:

[0027] The support assembly 1 includes: a support plate 11 for supporting the pipe fitting; and a positioning plate 12 disposed on the support plate 11 and having a positioning surface for positioning the pipe fitting.

[0028] The lifting component 2 is mounted on the support component 1 and is used for lifting and lowering in the vertical direction.

[0029] The sliding component 3 is located at the lifting end of the lifting component 2.

[0030] The cutting component 4 is slidably connected to the sliding component 3 and is used to cut the pipes on the support component 1.

[0031] In this invention, the support plate 11 and positioning plate 12 in the support assembly 1 cooperate to provide stable support and angular positioning for the pipe fitting, avoiding the problem of pipe fitting displacement that easily occurs in traditional cutting methods. In practical applications, when pipe fitting needs to be cut, the operator only needs to place the pipe fitting on the support plate 11 and ensure that the side wall of the pipe fitting is in contact with the positioning surface of the positioning plate 12 to complete the positioning of the pipe fitting. The cooperation of the lifting assembly 2, the sliding assembly 3, and the cutting assembly 4 realizes the guidance and control of the cutting process, overcoming the problems of uneven cutting surface and inaccurate cutting angle caused by unstable operation in traditional manual cutting. This structural design makes the entire cutting process more standardized and controllable, improving cutting quality and work efficiency.

[0032] Specifically, during building construction or pipeline installation, pipe fittings often need to be cut to accommodate corner connections. Traditional cutting methods rely heavily on manual operation, requiring workers to first mark the cutting position on the pipe fitting before cutting with a hand-held cutting tool. This method has several problems: firstly, the smooth surface of the pipe fitting makes marking difficult and prone to errors; secondly, the pipe fitting is prone to rotation during cutting, affecting cutting accuracy; and thirdly, hand-held cutting is prone to shaking, resulting in an uneven cut surface. This solution addresses the pipe fitting positioning and support issues through the design of support component 1. Support plate 11 provides a stable support surface for the pipe fitting, preventing displacement or rotation during cutting. The positioning surface on positioning plate 12 engages with the side wall of the pipe fitting, enabling quick determination of the cutting angle and maintaining the stability of the pipe fitting's position throughout the cutting process. This positioning method eliminates the need for complex measurement and marking processes, significantly improving work efficiency. The lifting component 2 makes the cutting process more controllable, allowing the operator to adjust the cutting depth according to the progress, avoiding uneven cut surfaces caused by cutting too quickly or too slowly. The sliding component 3 ensures the straightness of the cut, overcoming the defect of easily deviating from the cutting line when cutting by hand. The entire cutting process becomes more standardized and controllable, improving both cutting quality and reducing operational difficulty.

[0033] In some embodiments, the support assembly 1 further includes a base plate 13, on which the support plate 11 is rotatably mounted.

[0034] This embodiment of the invention adds a base plate 13, and a support plate 11 is rotatably mounted on the base plate 13. This design allows the support plate 11 to be adjusted in angle according to actual needs, adapting to different cutting angle requirements. In practical applications, when cutting bevels at different angles, the operator can rotate the support plate 11 to adjust the angle, avoiding the hassle of frequently adjusting the pipe position required in traditional cutting methods. This adjustable structural design greatly improves the practicality and adaptability of the device, enabling it to meet more diverse cutting needs.

[0035] Specifically, in practical engineering applications, pipe connections often require bevel cuts at different angles, such as 45 degrees and 60 degrees. Traditional cutting methods require adjusting the placement angle of the pipe fittings to achieve different angles, which is not only cumbersome to adjust but also difficult to guarantee the accuracy of the angle. This solution provides a simple and precise angle adjustment method by rotating the support plate 11 onto the base plate 13. The operator only needs to rotate the support plate 11 to adjust the cutting angle without moving or repositioning the pipe fittings. This design is particularly suitable for work scenarios that require batch cutting of the same angle. For example, when installing horizontal branch pipes, it is often necessary to cut multiple bevels at the same angle. Traditional methods require repeated measurements and adjustments, while this solution only requires setting the angle once for continuous cutting, significantly improving work efficiency. In addition, the rotating design of the support plate 11 also facilitates temporary adjustment of the cutting angle according to the site conditions, increasing the adaptability of the device.

[0036] In some embodiments, the support assembly 1 further includes a locking member 14 for locking the support plate 11 and the base plate 13.

[0037] In this invention, the problem of fixing the support plate 11 after adjustment is solved by adding a locking component 14. In practical applications, after the support plate 11 is adjusted to the required angle, the locking component 14 locks the support plate 11 and the base plate 13 in place, preventing the support plate 11 from rotating due to vibration during the cutting process. This locking structure ensures the stability of the workpiece position during the cutting process and is an important guarantee for ensuring cutting accuracy. Traditional cutting devices often lack this locking mechanism, which can easily affect the cutting quality due to instability of the support surface.

[0038] Specifically, the design of the locking element 14 addresses a key issue in actual cutting operations. At pipe installation sites, the cutting process often generates vibrations. If the connection between the support plate 11 and the base plate 13 is not secure enough, angular deviation can easily occur. This is especially true when cutting larger diameter or thicker-walled pipes, where greater cutting resistance makes it easier for the support plate 11 to rotate. The locking element 14 effectively solves this problem. After the operator adjusts the desired angle, the locking element 14 locks the support plate 11 and the base plate 13 together, forming a stable unit. This locking mechanism not only ensures sufficient locking force but also facilitates quick operation. In practical applications, common locking methods include bolt locking and quick-clamping, allowing the operator to choose the appropriate method based on site conditions. This reliable locking structure ensures the stability of the workpiece position throughout the cutting process, a crucial guarantee for cutting accuracy. From a long-term perspective, the locking structure also prevents the rotational connection between the support plate 11 and the base plate 13 from loosening due to repeated use, extending the lifespan of the device.

[0039] The locking component 14 can be a locking bolt, which is threadedly connected to the support plate 11. The bottom of the locking bolt abuts against the base plate 13. The locking and unlocking of the support plate 11 and the base plate 13 can be achieved by rotating the locking bolt.

[0040] In some embodiments, a circular scale 15 is provided on the base plate 13.

[0041] In this invention, a circular scale 15 is provided on the base plate 13, serving as a reference for angle adjustment. In practical applications, operators can quickly and accurately adjust the angle of the support plate 11 according to the scale, avoiding the cumbersome steps of measurement using tools such as protractors required in traditional methods. This design not only improves adjustment efficiency but also increases the accuracy of angle adjustment. This design is particularly valuable for work requiring batch cutting of beveled surfaces with the same angle, ensuring the consistency of the angle for each cut.

[0042] Specifically, the circular scale 15 reflects the deep consideration given to operational convenience in this design. In pipe installation projects, different types of pipe connections may require different cutting angles. Traditional angle measurement methods typically require the use of a protractor, which presents several problems: firstly, the on-site operating environment may be harsh, making the protractor prone to damage or loss; secondly, using a protractor requires additional time, reducing work efficiency; and thirdly, repeated use of a protractor can easily lead to cumulative errors. The circular scale 15 on the base plate 13 solves these problems. The scale can directly mark commonly used cutting angles, such as 30 degrees, 45 degrees, and 60 degrees, allowing operators to quickly and accurately adjust the angle by observing the scale. This design is even more advantageous for work requiring batch cutting. For example, when installing a complete 22-pipe system, multiple beveled interfaces with the same angle are often required. With the circular scale 15, the consistency of the angle of each cut surface can be ensured, improving installation quality. Furthermore, the permanent marking of the scale avoids the problems of easy wear and loss of external measuring tools.

[0043] In some embodiments, the lifting assembly 2 includes: four columns 21, the bottom of which is connected to the support assembly 1; and four sleeves 22, which are sleeved on the outer periphery of the four columns 21 and slidably connected to the four columns 21.

[0044] In this invention, a stable lifting mechanism is formed by adopting a structural design of four columns 21 and four sleeves 22. The four-point support design ensures the smoothness and balanced force distribution during the lifting process. In practical applications, this structure can effectively prevent the cutting component 4 from tilting or swaying during the lifting process, ensuring the accuracy of the cutting. Compared with traditional single-point or double-point support structures, the four-point support structure has better stability, especially when cutting longer pipes, this advantage is more obvious.

[0045] Specifically, the design of the four columns 21 and four sleeves 22 reflects the pursuit of cutting stability. In pipe cutting, the smooth movement of the cutting assembly 4 directly affects the cutting quality. If a single-point or double-point supported lifting structure is used, tilting or swaying is likely to occur, especially when cutting longer pipes, where this instability becomes more pronounced. The four-point support structure provides the optimal solution from a mechanical perspective. The four columns 21 are distributed at the four corners of the cutting area, forming a stable support frame. The sliding fit between the sleeves 22 and the columns 21 ensures smooth lifting movement. This design exhibits several advantages in practical applications: First, the four-point support provides greater load-bearing capacity, maintaining stability even when cutting heavier pipes; second, the dispersed support points reduce the stress on each support point, extending the service life of the components; third, the four-corner support structure also provides better torsional resistance, preventing deflection during the cutting process. Furthermore, the synchronous lifting of the four sleeves 22 ensures the levelness of the cutting plane, which is crucial for guaranteeing cutting quality.

[0046] In some embodiments, the cutting assembly 4 includes: a fixing frame 41, which is slidably connected to the sliding assembly 3; and a saw blade 42, which is disposed on the fixing frame 41.

[0047] In this invention, a practical cutting structure is formed by the combination of the fixing frame 41 and the saw blade 42. The sliding connection between the fixing frame 41 and the sliding component 3 ensures the movement trajectory during the cutting process. In practical applications, this structure makes the cutting action smoother and more controllable, avoiding the problem of easily deviating from the cutting line when using traditional hand-held cutting. The design of the fixing frame 41 also provides a basis for the subsequent addition of operating components such as the handle 43, making the entire cutting operation more user-friendly.

[0048] Specifically, the combined design of the fixing frame 41 and the saw blade 42 provides an effective solution to the problems of fixing and guiding the cutting tool. In traditional hand-held cutting methods, the cutting quality largely depends on the operator's experience and skill level. Even experienced operators are prone to fatigue and reduced cutting quality after prolonged hand-held cutting. This solution uses the fixing frame 41 to stably support the saw blade 42 and forms a reliable sliding connection with the sliding component 3. This design has significant advantages in practical applications: First, the design of the fixing frame 41 eliminates the shaking problem during hand-held cutting, making the cutting process smoother; second, the cooperation with the sliding component 3 ensures the accuracy of the cutting direction and avoids deviation during the cutting process; third, the design of the fixing frame 41 also provides a point of leverage for operation, allowing the operator to better control the cutting force. This structural design not only improves cutting accuracy but also reduces the operator's labor intensity.

[0049] In some embodiments, the end of the mounting bracket 41 is provided with a handle 43.

[0050] In this invention, a handle 43 is added to the end of the fixing frame 41, improving operability. In practical applications, the handle 43 allows the operator to better control the cutting force and speed, improving operational comfort and safety. This design takes ergonomic requirements into account, reducing operator fatigue, especially during long-term cutting operations, where this advantage is more pronounced.

[0051] Specifically, the design of handle 43 reflects the ergonomic considerations of this solution. In pipe cutting, operators often need to perform repetitive tasks for extended periods. If the cutting tool's design is not user-friendly, it can easily lead to operator fatigue, affecting work efficiency and cutting quality. The handle 43 at the end of the mounting bracket 41 improves operating conditions in several ways: First, handle 43 provides a suitable grip position, allowing the operator to cut in the most natural posture, reducing wrist and arm fatigue; second, handle 43 allows for better control of cutting force, enabling the operator to adjust the applied force according to the actual situation when cutting pipes of different materials or wall thicknesses; third, handle 43 also facilitates timely adjustments to the cutting speed during the cutting process, allowing for adjustments to the operating method when encountering changes in pipe material or increased cutting resistance. Especially in confined spaces or inconvenient operating locations, the well-designed handle 43 demonstrates its value, helping the operator maintain a stable cutting motion. From a long-term use perspective, this user-friendly design not only improves work efficiency but also reduces the risk of occupational injury for operators.

[0052] In some embodiments, the sliding component 3 is a horizontally arranged guide tube 31, and the fixing bracket 41 passes through the guide tube 31.

[0053] In this invention, the horizontal guide tube 31 provides a stable movement trajectory for the cutting assembly 4. In practical applications, the guide tube 31 restricts the movement direction of the fixing frame 41, ensuring that it can only move along a predetermined straight line during the cutting process, effectively avoiding deviation during cutting. This design plays an important role in improving cutting accuracy, especially when cutting longer pipes, ensuring the straightness of the cut surface.

[0054] Specifically, the design of the horizontal guide tube 31 provides a reliable guarantee for controlling the straightness of the cut. In pipe cutting, the straightness of the cut surface directly affects the sealing and robustness of subsequent pipe connections. Traditional handheld cutting methods struggle to guarantee the straightness of the cutting trajectory, especially when cutting large-diameter pipes. This solution utilizes the horizontal guide tube 31 structure, solving this problem from a mechanical constraint perspective. The guide tube 31 design offers multiple advantages: First, its circular structure provides omnidirectional restraint on the fixing frame 41, ensuring the cutting motion remains strictly on the predetermined straight trajectory; second, the guide tube 31 design prevents deflection and swaying during the cutting process, maintaining stability even under significant cutting forces; third, the length of the guide tube 31 can be designed according to actual needs, adapting to the cutting requirements of pipes with different diameters. In practical applications, this guide structure is particularly suitable for applications requiring high-precision cutting, such as the installation of demanding industrial pipelines. The guide tube 31 design also considers maintenance factors, facilitating cleaning and lubrication, ensuring long-term reliability.

[0055] In some embodiments, the sliding component 3 is a square steel with a U-shaped groove on the top, and the fixing frame 41 is inserted into the U-shaped groove.

[0056] This embodiment of the invention provides another implementation of the sliding component 3, employing a square steel structure with a U-shaped groove. This design also guides the movement of the fixing frame 41, and is simpler in structure and lower in manufacturing cost. In practical applications, the U-shaped groove design can limit the fixing frame 41 from two directions, ensuring the stability of the cutting process. This structure is particularly suitable for cost-sensitive applications.

[0057] Specifically, the U-shaped channel square steel design provides a simple and practical guiding solution. In practical engineering applications, the manufacturing cost and maintenance difficulty of the equipment are key factors to consider. Compared to the guide tube 31 structure, the U-shaped channel square steel design has unique advantages: First, this structural form is simple and has low manufacturing process requirements, which can greatly reduce production costs; second, the open U-shaped channel structure is easy to clean and maintain, preventing chip accumulation from affecting sliding; third, the U-shaped channel design can still provide good guiding effect, with bidirectional limiting of the fixed frame 41 through the channel wall. This design is particularly suitable for occasions where precision requirements are not particularly strict, but cost-effectiveness needs to be considered. For example, in general construction sites, the operating environment may be harsh, and the equipment is easily affected by dust and debris; the open structure of the U-shaped channel is easier to maintain. In addition, this structure has strong resistance to deformation, maintaining good guiding effect even in harsh environments.

[0058] In some embodiments, a cleaning blade 23 is provided on the sleeve 22, and a strip-shaped cleaning opening 231 is provided at the bottom of the cleaning blade 23. The saw blade 42 passes through the strip-shaped cleaning opening 231, and the cleaning blade 23 abuts against the surface of the saw blade 42.

[0059] In this invention, a cleaning blade 23 is installed on the sleeve 22, solving the problem of cleaning the saw blade 42 during the cutting process. The strip-shaped cleaning opening 231 at the bottom of the cleaning blade 23 cooperates with the saw blade 42, automatically removing chips adhering to the saw blade 42 during cutting. In practical applications, this design avoids the inconvenience of frequent machine stops for cleaning the saw blade 42, improving work efficiency. The abutting design between the cleaning blade 23 and the saw blade 42 ensures the cleaning effect without affecting the normal operation of the saw blade 42. This automatic cleaning function is of great significance for improving cutting efficiency and extending the service life of the saw blade 42.

[0060] Specifically, the design of the cleaning blade 23 reflects the consideration of the continuity of the cutting process in this solution. Timely chip removal is a crucial factor affecting cutting efficiency and quality during pipe cutting. Traditional cutting methods require periodic shutdowns to clean the saw blade 42, which not only reduces work efficiency but may also affect the continuity of the cut surface. This solution achieves automatic chip removal by installing the cleaning blade 23 on the sleeve 22. This design demonstrates significant advantages in practical applications: First, the cooperation between the cleaning blade 23 and the saw blade 42 allows for simultaneous cutting and cleaning, eliminating the need for additional cleaning time; second, the design of the strip-shaped cleaning opening 231 ensures effective cleaning without affecting the normal operation of the saw blade 42; third, the contact design between the cleaning blade 23 and the saw blade 42 ensures thorough cleaning and prevents chip accumulation on the saw blade 42. This automatic cleaning function plays a vital role in improving work efficiency, especially during continuous cutting operations, maintaining stable cutting quality. From a service life perspective, timely chip removal also reduces wear on the saw blade 42, extends tool life, and lowers maintenance costs.

[0061] This cutting device, through the cooperation of the support plate 11 and positioning plate 12 in the support assembly 1, can stably support and position the pipe fitting at an angle, avoiding the problem of pipe fitting displacement that easily occurs in traditional cutting methods. In practical applications, when pipe fitting needs to be cut, the operator only needs to place the pipe fitting on the support plate 11 and ensure that the side wall of the pipe fitting is in contact with the positioning surface of the positioning plate 12 to complete the positioning of the pipe fitting. The cooperation of the lifting assembly 2, the sliding assembly 3, and the cutting assembly 4 realizes the guidance and control of the cutting process, overcoming the problems of uneven cutting surface and inaccurate cutting angle caused by unstable operation in traditional manual cutting, thereby improving cutting quality and work efficiency.
