[0030] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0031] The large pipe multi-angle cutting machine in this embodiment relates to the field of pipeline cutting technology, and is used to fix a relatively heavy large pipe so that it remains stationary. The saw blade 220 is rotated by using a turntable 110 and a door-shaped frame 120, so that the saw blade 220 and the pipe have a certain inclination angle, so that the end of the pipe can be cut obliquely to facilitate the discharge of sewage.

[0032] See also Figures 1 to 4 A large-scale multi-angle pipe cutting machine in this embodiment includes a rotating assembly 100, a sawing assembly 200 and a driving assembly 300. The sawing assembly 200 is provided with a reciprocating saw blade 220, which can cut off the end of the pipe as needed to form an oblique incision.

[0033] The rotating assembly 100 includes a rotatable turntable 110 and a portal frame 120. The turntable 110 can be rotated to a specific angle as needed. The two sides of the portal frame 120 are fixedly connected to the turntable 110 respectively. A space for accommodating pipes is formed between the portal frame 120 and the turntable 110. The turntable 110 can drive the portal frame 120 to rotate relative to each other, so that a certain angle is formed between the portal frame 120 and the pipe, and the angle of the inclined cut of the pipe can be controlled to meet the needs of pipes with different uses.

[0034] The sawing assembly 200 includes two movable units 210 and a reciprocating saw blade 220. The two movable units 210 are respectively slidably engaged with the two sides of the gantry frame 120. The movable units 210 can move along the gantry frame 120. The two ends of the saw blade 220 are respectively connected to the two movable units 210. The saw blade 220 can reciprocate between the two movable units 210 as the main motion of the tool to perform transverse cutting on the pipe.

[0035] The driving assembly 300 is disposed between the turntable 110 and the moving unit 210 . The driving assembly 300 can drive the moving unit 210 to move relative to the gantry frame 120 , thereby driving the saw blade 220 to feed longitudinally, thereby achieving deep cutting of the pipe.

[0036] During use, the pipe is fixed between the door-shaped frame 120 and the turntable 110. By adjusting the turntable 110, the door-shaped frame can be rotated relative to the pipe, and the saw blade 220 maintains a set angle with the pipe, and the saw blade 220 reciprocates to cut. The driving assembly 300 drives the moving unit 210 to move along the door-shaped frame 120, thereby driving the saw blade 220 to move relative to the turntable 110, completing the oblique cutting of the pipe and forming a corresponding opening with an inclination.

[0037] In some embodiments, see Figure 1 and Figure 2The sawing assembly 200 also includes a reciprocating drive unit 230, and the saw blade 220 is connected to the moving unit 210 via the reciprocating drive unit 230. The reciprocating drive unit 230 can drive the saw blade 220 to reciprocate relative to its own length direction. The saw blade 220 that reciprocates along the length direction can maintain a high speed and stability during cutting, which helps to reduce vibration and deformation of the pipe during cutting and ensure the flatness and consistency of the incision.

[0038] The reciprocating drive unit 230 includes a rotating drive member 231 installed on the mobile unit 210 and a reciprocating transmission mechanism. The reciprocating drive mechanism can be a crank-connecting rod mechanism, which consists of three parts: a crank, a connecting rod and a piston. The rotating drive member 231 is rotatably connected to the crank, the saw blade 220 is connected to the piston, and the connecting rod is respectively connected to the crank and the piston. When the crank rotates, the connecting rod drives the piston to move along a straight path to realize reciprocating drive of the saw blade 220.

[0039] The reciprocating drive structure may be a reciprocating gear structure. When the reciprocating gear rotates, a portion of the outer gear teeth may drive the saw blade 220 to move back and forth.

[0040] Please continue reading Figure 1 and Figure 2 The moving unit 210 includes a slider 211, which is slidably engaged with the door-shaped frame 120. The slider 211 can move vertically relative to the door-shaped frame 120. The slider 211 can maintain the stability and balance of the pipe during the cutting process to prevent cutting deviation or pipe damage due to imbalance.

[0041] The sliders 211 of the two movable units 210 are connected by a connecting piece 240. The two sliders 211 can move synchronously. The synchronous movement ensures that the incisions on both sides remain symmetrical during the cutting process, avoiding inconsistent incision positions and deformation of the pipe. The synchronous movement of the sliders 211 also helps to improve cutting efficiency, ensures stability and consistency during the cutting process, and reduces processing time and labor costs.

[0042] In some embodiments, the door-shaped frame 120 includes two oppositely arranged vertical rods 121 and a crossbeam 122, and the two ends of the crossbeam 122 are respectively connected to the tops of the two vertical rods 121. The connection between the vertical rods 121 and the crossbeam 122 enables the door-shaped frame 120 to withstand greater pressure and force, thereby ensuring stability and safety during the cutting process. The bottom of the vertical rod 121 is detachably connected to the turntable 110, and the turntable 110 can be easily installed and removed from the vertical rods 121, which can simplify the assembly process of the equipment and facilitate the maintenance and repair of the equipment.

[0043] In some embodiments, see Figure 1 and Figure 2A guide unit 250 is provided between the crossbeam 122 and the turntable 110. The guide unit 250 includes a guide column 251 and a guide hole. The two ends of the guide column 251 are respectively connected to the crossbeam 122 and the turntable 110. The guide hole is provided on the slider 211, and the guide column 251 is slidably inserted into the guide hole. The guide column 251 connects the crossbeam 122 and the turntable 110 to ensure the relative position and direction between them, so that each component in the cutting process can maintain good alignment and stability. The guide column 251 is slidably inserted into the guide hole to form a sliding connection. The friction between the crossbeam 122 and the turntable 110 can be reduced, the energy loss during the cutting process can be reduced, and the operating efficiency of the equipment can be improved. The design of the guide unit 250 also helps to reduce vibration and noise, and improve the stability and comfort of use of the equipment.

[0044] The driving assembly 300 includes a linear driving member 310, the two ends of which are connected to the moving unit 210 and the turntable 110 respectively. The linear driving member 310 can drive the saw blade 220 to move up and down along the door-shaped frame 120, thereby achieving precise control of the cutting depth, and adjusting the up and down moving distance of the saw blade 220, thereby achieving precise control of the cutting depth of the pipe. Driven by the linear driving member 310, the saw blade 220 can move up and down along the door-shaped frame 120, quickly complete the cutting of the pipe, and improve the cutting efficiency.

[0045] In the specific implementation process, the linear drive component 310 is specifically an electric push rod, a cylinder, a hydraulic cylinder, a screw transmission device or a linear motor. The above devices can achieve the function of linearly driving the sawing assembly 200 to move vertically, thereby achieving the purpose of cutting the pipe by feeding motion.

[0046] In some embodiments, see Figure 3 and Figure 4 The large-scale multi-angle pipe cutting machine also includes a clamping frame 400 for clamping the pipe, which provides a stable fixation and support for the pipe, so that it maintains a stable position and posture during the cutting process. This helps to ensure the accuracy and consistency of the cutting, avoids the movement or shaking of the pipe during the cutting process, and thus improves the quality and accuracy of the cutting.

[0047] In the specific implementation process, the clamping frame 400 is a frame structure, and a load-bearing plate is provided in the middle of the frame structure. The frame located above the load-bearing plate can constrain both sides of the pipe, and the load-bearing plate can bear the weight of the pipe. A mechanical clamping and fixing device can be provided on the frame located above the load-bearing plate, and a restraining belt can also be provided to stably fix the pipe on the frame structure, so as to facilitate the sawing assembly 200 to cut the pipe.

[0048] The turntable 110 is arranged in the lower frame of the clamping frame 400, and the door-shaped frame 120 is connected to the turntable 110 protruding from both ends of the clamping frame 400, so that the various components of the equipment are well coordinated and cooperated, avoiding interference and collision during the cutting process, and ensuring the safety and stability of the equipment.

[0049] In the specific implementation process, please refer to Figure 1 A reinforcement plate is provided on the turntable 110, the middle part of the reinforcement plate is connected to the turntable 110 by bolts, and the two ends of the reinforcement plate are respectively connected to the two vertical rods 121. The reinforcement plate serves as the protruding part of the turntable 110 from the two ends of the clamping frame 400, so that the door-shaped frame body 120 can be away from the clamping frame 400, avoiding interference and collision between the clamping frame 400 and the door-shaped bracket during the cutting process.

[0050] In some embodiments, see Figure 3 and Figure 4 The clamping frame 400 is provided with a cutting groove 410 for cooperating with the saw blade 220. The cutting groove 410 is embedded in the support plate, and the pipe abutting the support plate can be completely cut by the saw blade 220, thereby improving the accuracy and consistency of cutting.

[0051] Workflow: First, move the pipe onto the support plate, clamp and fix the pipe. Then, start the turntable 110 to rotate, adjust the saw blade 220 to a preset angle appropriate to the pipe, start the sawing assembly 200, and the saw blade 220 moves back and forth. Next, start the linear drive 310, which drives the sawing assembly 200 to move downward along the door-shaped frame 120 as a whole, obliquely cut the end of the pipe, and form a port with a certain slope.

[0052] The above description is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be covered by the present invention.
