Description

Technical Field

[0001] This utility model relates to the field of cutting technology, specifically to an automatic feeding cutting machine. Background Technology

[0002] Steel pipes are steel materials with a hollow cross-section, whose length is much greater than its diameter or circumference. They are classified according to cross-sectional shape into round, square, rectangular, and irregularly shaped steel pipes; according to material into carbon structural steel pipes, low alloy structural steel pipes, alloy steel pipes, and composite steel pipes; and according to application into pipes for transportation, engineering structures, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, and high-pressure equipment. When steel pipes need to be cut, a cutting machine is used to cut them into the same length.

[0003] For example, Chinese patent CN218476080U discloses an automatic steel pipe feeding and cutting machine. This patent uses a fixed structure and a first electric telescopic rod to drive a second fixed block towards the first fixed block, thus fixing the steel pipe. The feeding mechanism allows the sliding block to move synchronously with the fixed structure after the steel pipe is fixed, achieving feeding. This mechanical feeding, replacing manual feeding, improves both equipment efficiency and worker safety. A geared motor drives a connecting column to rotate, which in turn drives the cutting blade. The second electric telescopic rod then drives the mounting box and cutting blade to move synchronously downwards, bringing the cutting blade into contact with the steel pipe for cutting. The moving and fixed clamping blocks have grooves at their tops that match the cutting blade, facilitating subsequent cutting and improving the machine's practicality. However, because the steel pipe is cut by rotating the cutting blade, which has high hardness, the blade wears out quickly, reducing its lifespan and increasing cutting costs and blade replacement frequency.

The steel pipe can be automatically fed and cut, and the wear of the cutting blade can be reduced during the cutting process, improving the service life of the cutting blade and the efficiency of cutting the steel pipe.

[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. 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.

[0023] Example 1

[0024] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6An automatic feeding and cutting machine includes a worktable 1, on the top surface of which a first drive motor 2 is fixedly mounted. A lead screw 3 is fixedly mounted at one end of the drive shaft of the first drive motor 2, and a connecting block 4 is threadedly connected to the outer wall of the lead screw 3. A cutting assembly is also included, located on the top surface of the worktable 1, for cutting steel pipes. The cutting assembly includes a second electric push rod 21, fixedly mounted on the top surface of the worktable 1. A second mounting block 22 is fixedly mounted on the top surface of the telescopic shaft of the second electric push rod 21. A connecting rod 23 is fixedly mounted on one side of the second mounting block 22. A protective shell 24 is fixedly mounted at one end of the connecting rod 23. A connecting frame 30 is fixedly mounted on the top surface of the protective shell 24. The top surface of the protective shell 24 has several drainage holes 31. A second drive motor 25 is fixedly installed on one side of the protective shell 24. The drive shaft of the second drive motor 25 extends into the interior of the protective shell 24. A connecting pipe 26 is movably sleeved on the outer circular wall of the drive shaft of the second drive motor 25. A cutting blade 29 is fixedly installed at one end of the connecting pipe 26. A connecting post 5 is fixedly installed on the top surface of the connecting block 4. A first mounting block 6 is fixedly installed on the top surface of the connecting post 5. A fixing block 7 is fixedly installed on the top surface of the first mounting block 6. A fixing opening 8 is opened on one side of the fixing block 7. A shell 14 is fixedly installed on the top surface of the workbench 1. The shell 14 has a hollow rectangular structure. A moving opening 15 is opened on the top surface of the shell 14. The moving opening 15 connects to the connecting post. 5. The housing 14 is movably sleeved with the first mounting block 6. By setting the fixing block 7, before cutting the steel pipe, the steel pipe is placed inside the fixing opening 8 on the fixing block 7, and then the steel pipe is fixed in the fixing opening 8. After the steel pipe is fixed, the first drive motor 2 can be started, causing the drive shaft of the first drive motor 2 to rotate the screw 3. While the screw 3 is rotating, the connecting block 4 can move on the screw 3 through the thread, so that the first mounting block 6 can be moved through the connecting column 5. The first mounting block 6 and the fixing block 7 feed the fixed steel pipe while moving. At this time, the second drive motor 25 and the second electric push rod 21 can be started, so that the second drive motor 25 drives the first mounting block 6 through the drive shaft. As the cutting blade 29 rotates, and with the downward movement of the telescopic shaft of the second electric push rod 21, the rotating cutting blade 29 cuts the steel pipe fed below it. While cutting the steel pipe, cutting fluid can be poured into the interior of the connecting frame 30, allowing it to flow through the drain hole 31 onto the cutting blade 29. This reduces the coefficient of friction between the cutting blade 29 and the steel pipe, lowering the temperature generated during cutting. The cut steel pipe can then be processed, enabling automatic feeding and cutting. This process also reduces wear on the cutting blade 29, extending its service life and improving the efficiency of cutting the steel pipe.

A movable opening 13 is opened on the top surface of the fixing block 7. The movable opening 13 communicates with the inside of the fixing opening 8. A fixing ring 9 is fixedly installed on the bottom surface of the telescopic shaft of the first electric push rod 12 and the inner circular wall of the fixing opening 8, respectively. By setting the fixing ring 9, after the steel pipe is placed inside the fixing opening 8, the outer wall of the steel pipe is attached to the fixing ring 9 inside the fixing opening 8. At this time, the telescopic shaft of the first electric push rod 12 can be activated to push the upper fixing ring 9 downward, so that the upper fixing ring 9 presses down against the steel pipe, thereby fixing the steel pipe between the two fixing rings 9 inside the fixing opening 8, so that the steel pipe remains stable while being cut and avoids shaking.

[0027] Example 3

[0028] Based on the above embodiment 1 or 2, refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A mounting plate 16 is fixedly installed on the top surface of the workbench 1. A mounting hole 17 is opened on one side of the mounting plate 16. A bearing 18 is fixedly sleeved on the inner circular wall of the mounting hole 17. The lead screw 3 is fixedly sleeved with the inner ring of the bearing 18. By setting the bearing 18, the bearing 18 can support the lead screw 3, thereby improving the stability of the lead screw 3 when rotating. Two cutting frames 19 are fixedly installed on the top surface of the workbench 1. By setting the cutting frames 19, the cutting frames 19 can support the steel pipe being cut, so that the steel pipe remains stable when being cut. The outer circular wall of the drive shaft of the second drive motor 25 and the outer circular wall of the connecting pipe 26 are both provided with threaded holes 27. A threaded rod 28 is threadedly connected to the inner circular wall of the threaded hole 27. By setting the threaded rod 28, the threaded rod 28 can be used to cut the steel pipe. After being unscrewed from the threaded hole 27, the cutting blade 29 can be disassembled and replaced. A collection box 20 is provided on the top surface of the workbench 1. By providing the collection box 20, the debris generated from cutting the steel pipe can be collected. The top and bottom surfaces of the connecting block 4 are respectively in contact with the top and bottom surfaces of the inner surface of the housing 14 to prevent the connecting block 4 from shaking as the lead screw 3 rotates. In this solution, the first drive motor 2, the first electric push rod 12, the second electric push rod 21 and the second drive motor 25 are all powered by a battery or by the power supply system of the workbench 1. When in use, they can be controlled and started by the controller provided on the workbench 1. The power supply method and control method are existing technologies, so they will not be described in detail in this solution.

[0029] Working principle: Please refer to Figures 1-6As shown, by setting the fixing block 7, before cutting the steel pipe, the steel pipe is placed inside the fixing opening 8 on the fixing block 7. After the steel pipe is placed inside the fixing opening 8, the outer wall of the steel pipe is pressed against the fixing ring 9 inside the fixing opening 8. At this time, the telescopic shaft of the first electric push rod 12 can be activated to push the upper fixing ring 9 downward, so that the upper fixing ring 9 presses down against the steel pipe, thereby fixing the steel pipe between the two fixing rings 9 inside the fixing opening 8. After fixing the steel pipe, the first drive motor 2 can be activated, so that the drive shaft of the first drive motor 2 rotates the screw 3. While the screw 3 rotates, the connecting block 4 can move on the screw 3 through the thread, so that the first mounting block 6 can be moved through the connecting column 5, so that the first mounting block 6 and the fixing block 7 feed the fixed steel pipe while moving. At this time, the second drive motor 25 and the second electric push rod 21 can be started, so that the second drive motor 25 drives the cutting blade 29 to rotate through the drive shaft. In addition, the downward movement of the telescopic shaft of the second electric push rod 21 causes the rotating cutting blade 29 to cut the steel pipe fed below the cutting blade 29. While cutting the steel pipe, cutting fluid can be poured into the interior of the connecting frame 30, so that the cutting fluid flows to the cutting blade 29 through the drain hole 31, thereby reducing the friction coefficient between the cutting blade 29 and the steel pipe and reducing the temperature generated by the cutting between the cutting blade 29 and the steel pipe. After that, the cut steel pipe can be processed. The steel pipe can be automatically fed and cut, and the wear of the cutting blade 29 during the cutting process can be reduced, thereby improving the service life of the cutting blade 29 and improving the efficiency of cutting the steel pipe.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
