Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, and in particular to an automatic cutting machine for metal square tubes. Background Technology

[0002] The automatic metal square tube cutting machine is a highly automated piece of equipment, mainly used for cutting square tubes of various metal materials. It can automatically complete the cutting operation of metal square tubes according to preset parameters, such as cutting length and cutting speed, reducing manual intervention and improving cutting efficiency and accuracy.

[0003] First, the equipment must be shut down and the power disconnected to ensure safety. For some cutting machines that use bolts to fix the blades, appropriate tools (such as wrenches) should be used to loosen and remove the bolts fixing the blades. After removing the old blades, the new blades should be installed in the corresponding positions and then fixed with bolts or other fixing devices. The heat generated by the blades is mainly dissipated naturally through heat exchange with the surrounding air. After cutting, the operator should use brooms, dustpans, and other tools to sweep up the scattered metal scraps on the cutting worktable and around the equipment. For some larger pieces of scrap, they should be picked up by hand and put into the scrap collection bin.

[0004] The entire tool replacement process is cumbersome and time-consuming, leading to increased equipment downtime and severely impacting production efficiency. Improper operation during disassembly and installation can easily damage the tools, such as scratching the cutting edge or deforming them, increasing tool wear and tear costs. Natural cooling is generally insufficient under high-load cutting conditions, and manual cleaning and collection are extremely time-consuming, especially with frequent cutting tasks and high waste generation. Each cleaning and collection session can take several minutes to over ten minutes, interrupting the normal cutting workflow and affecting overall production efficiency. Manual cleaning is also insufficient to remove all waste; small waste particles remain in corners, crevices, or on the floor, and are easily scattered again with personnel movement and equipment operation, affecting workplace cleanliness. To address these issues, an automatic metal square tube cutting machine is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an automatic cutting machine for metal square tubes, which solves the problems of low efficiency in changing tools, easy damage to tools, reliance on natural cooling of tools, and the need for manual cleaning of waste materials in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic cutting machine for metal square tubes, comprising a worktable, a push rod motor fixedly connected to the top of one side of the worktable, a moving plate fixedly connected to the output end of the push rod motor, a first motor fixedly connected to the bottom of the moving plate, a lock housing fixedly connected to the output end of the first motor, a sliding button slidably connected to one side of the outer wall of the lock housing, a spring sleeved on the outer wall of the sliding button, sliders provided at both ends of the inner wall of the lock housing, a fixed rod slidably connected to one side of the inner wall of the lock housing, a cutting blade fixedly connected to one side of the outer wall of the fixed rod, a cooling assembly for cooling the cutting blade provided at the top of the rear end of one side of the worktable, and a collection assembly for collecting waste material provided on the inner wall of one side of the worktable.

[0007] By adopting the above technical solution, the push rod motor is started, and its output end drives the moving plate to move. The moving plate drives the first motor to move. The first motor is started, and its output end drives the lock housing, which in turn drives the cutting blade to cut the square tube. After the sliding button squeezes the spring, the fixing rod is taken out. When the fixing rod is taken out, the slider is squeezed. After replacing the new cutting blade, the fixing rod is inserted back. The sliding button is released to reset it and fix the slider, thereby realizing quick blade change.

[0008] As a further description of the above technical solution: the collection component includes a collection tank, the outer wall of the collection tank is connected to and fixedly connected to the inner wall of one side of the workbench, a discharge pipe is fixedly connected to the bottom of the collection tank, and a collection box is connected to and fixedly connected to the bottom of the discharge pipe.

[0009] By adopting the above technical solution, the waste generated from cutting enters the collection tank, then enters the discharge pipe from the collection tank, and finally falls into the collection box.

[0010] As a further description of the above technical solution: a door is provided on one side of the collection box, a handle is fixedly connected to the rear end of one side of the door, a fan is fixedly connected to the other side of the collection box, and a filter screen is fixedly connected to the inner wall of the other side of the collection box.

[0011] By adopting the above technical solution, the fan is started, and the fan generates suction to draw the waste into the collection tank. The waste can be cleaned or recycled by opening the box door with the handle. The filter screen protects the fan and prevents it from being damaged by impurities.

[0012] As a further description of the above technical solution: the cooling assembly includes a gas storage tank, the bottom of which is fixedly connected to the top of the rear end of one side of the workbench, an air pump is fixedly connected to the bottom of the inner wall of the gas storage tank, and a hose is fixedly connected to the bottom of the air pump.

[0013] By adopting the above technical solution, the gas storage tank stores compressed air, and when the air pump is started, the compressed air is delivered to the hose.

[0014] As a further description of the above technical solution: a valve is connected through and fixedly connected to the middle of the outer wall of the hose, a vortex chamber is connected through and fixedly connected to the bottom of the outer wall of the hose, a separation orifice plate is fixedly connected to the front end of the inner wall of the vortex chamber, and a cold end pipe is fixedly connected to the inner wall of the separation orifice plate.

[0015] By adopting the above technical solution, the valve regulates the flow rate of compressed air in the hose, thereby controlling the cooling capacity. The separation orifice plate is mainly used to separate hot and cold fluids. Compressed air enters the vortex chamber and forms a high-speed vortex. Centrifugal force causes the gas to separate into light and heavy parts. Molecular friction and collision lead to energy separation. Low-temperature gas is discharged from the cold end to cool the cutting blade.

[0016] As a further description of the above technical solution: a hot end pipe is fixedly connected to the rear end of the vortex chamber, and a hot end control valve is fixedly connected to the rear end of the hot end pipe.

[0017] By adopting the above technical solution, high-temperature gas is discharged from the hot end pipe, and the hot end control valve is used to control the flow rate of the hot fluid. The hot end control valve can precisely adjust the temperature to achieve the best cooling effect.

[0018] As a further description of the above technical solution: a second motor is fixedly connected to the front end of the workbench, and a bidirectional threaded rod is fixedly connected to the output end of the second motor.

[0019] By adopting the above technical solution, the second motor is started, and its output drives the bidirectional threaded rod to rotate.

[0020] As a further description of the above technical solution: both ends of the bidirectional threaded rod are threaded with nut pairs, and the top of the nut pairs is fixedly connected with a fixing clamp.

[0021] By adopting the above technical solution, the rotation of the bidirectional threaded rod causes the nut pair to move, thereby moving the fixing clamp and fixing the square tube.

[0033] 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.

[0034] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0035] Combination Figure 1 and Figure 4 This utility model discloses an automatic cutting machine for metal square tubes, including a worktable 5. The worktable 5 provides a stable operating platform for the entire automatic cutting machine. A push rod motor 1 is fixedly connected to the top of one side of the worktable 5. A moving plate 3 is fixedly connected to the output end of the push rod motor 1. When the push rod motor 1 is started, the output end of the push rod motor 1 drives the moving plate 3 to move. A first motor 4 is fixedly connected to the bottom of the moving plate 3. The first motor 4 provides power for the rotation of the cutting blade 13. The cutting blade 13 is fixedly connected to one side of the outer wall of the fixed rod 21. The cutting blade 13 is the component that directly cuts the metal square tube. A waste collection component is provided on the inner wall of one side of the worktable 5. The main function of the collection component is to collect the waste generated during the cutting of the metal square tube. This waste includes metal chips, residues, etc. If not collected in time, it will scatter on the worktable. On platform 5, the cutting operation is affected and damages the cutting equipment. By collecting waste, the collection component can keep platform 5 and its surrounding working environment clean. A clean working environment helps improve the operator's work efficiency, reduces the occurrence of equipment failure, and facilitates subsequent processing or treatment of the cut metal square tube. A second motor 9 is fixedly connected to the front end of platform 5. A bidirectional threaded rod 26 is fixedly connected to the output end of the second motor 9. Nut pairs 27 are threaded to the outer walls of both ends of the bidirectional threaded rod 26. A fixing clamp 10 is fixedly connected to the top of the nut pairs 27. When the second motor 9 is turned on, the rotational power at its output end drives the bidirectional threaded rod 26 to rotate. Due to the thread transmission principle, the rotation of the bidirectional threaded rod 26 causes the nut pairs 27 to move, which in turn drives the fixing clamp 10 connected to it to move, ultimately realizing the fixing operation of the square tube.

[0036] Combination Figures 1-3 and Figure 6The output end of the first motor 4 is fixedly connected to a lock housing 17. A sliding button 18 is slidably connected to one side of the outer wall of the lock housing 17. A spring 20 is sleeved on the outer wall of the sliding button 18. Slider blocks 19 are provided at both ends of the inner wall of the lock housing 17. A fixed rod 21 is slidably connected to one side of the inner wall of the lock housing 17. First, the sliding button 18 is slid, which will compress the spring 20. Then, the fixed rod 21 can be removed. When the fixed rod 21 is removed, it will compress the slider 19 into the lock hole of the sliding button 18. Then, a new cutting blade 13 is replaced, and the fixed rod 21 is inserted into the lock housing 17. After that, the sliding button 18 is loosened, and the spring 20 drives the sliding button 18 to reset. Slide button 18 presses slider 19, fixing slider 19 to fixed rod 21, enabling quick replacement of cutting blade 13. A cooling assembly for cooling cutting blade 13 is located at the top of the rear end of one side of the workbench 5. The cooling assembly includes a gas storage tank 2 for storing compressed air. The bottom of the gas storage tank 2 is fixedly connected to the top of the rear end of one side of the workbench 5. An air pump 29 is fixedly connected to the bottom of the inner wall of the gas storage tank 2. The air pump 29 is responsible for drawing gas from the gas storage tank 2 and pressurizing it. The pressurized gas can flow to the vortex chamber 14 at a higher speed and pressure, thereby improving cooling efficiency. A hose 16 is fixedly connected to the bottom of the air pump 29. 6 serves as a gas transmission channel, delivering the pressurized gas from the air pump 29 to the vortex chamber 14. A valve 15 is fixedly connected and runs through the middle of the outer wall of the hose 16. The valve 15 can regulate the gas flow rate through the hose 16, thereby achieving precise control of the cooling effect. The vortex chamber 14 is fixedly connected and runs through the bottom of the outer wall of the hose 16. After the compressed air enters the vortex chamber 14, it forms a high-speed rotating vortex. Due to centrifugal force, the gas is divided into two parts: heavier gas molecules are thrown to the outside of the vortex chamber 14, while lighter gas molecules gather towards the center. During this process, air molecules rub and collide with each other, resulting in energy separation, thus separating the incoming high-pressure gas. The vortex chamber 14 is divided into two airflows, one cold and one hot. A separation orifice plate 22 is fixedly connected to the front end of the inner wall of the vortex chamber 14. The separation orifice plate 22 separates the cold and hot fluids. A cold end pipe 23 is fixedly connected to the inner wall of the separation orifice plate 22. The cold end pipe 23 outputs the cooled gas after being processed by the separation orifice plate 22 to the cutting area. A hot end pipe 24 is fixedly connected to the rear end of the vortex chamber 14. The hot end pipe 24 outputs the hot gas generated in the vortex chamber 14. A hot end control valve 25 is fixedly connected to the rear end of the hot end pipe 24. The hot end control valve 25 can adjust the flow rate of the hot gas passing through the hot end pipe 24. By controlling the flow rate of the hot gas, the temperature and flow rate of the gas output by the cold end pipe 23 can be indirectly affected, thereby achieving fine adjustment of the cooling effect.

[0037] Combination Figure 1 and Figure 5The collection assembly includes a collection trough 11. During the cutting of the metal square tube, the waste generated during cutting (such as metal shavings, residue, etc.) will first fall into the collection trough 11. The outer wall of the collection trough 11 penetrates and is fixedly connected to the inner wall of one side of the workbench 5. A discharge pipe 12 is fixedly connected to the bottom of the collection trough 11. The discharge pipe 12 is a channel connecting the collection trough 11 and the collection box 6, responsible for transferring the waste in the collection trough 11 to the collection box 6. The bottom of the discharge pipe 12 penetrates and is fixedly connected to the collection box 6. The discharge pipe 12 is used to finally contain the waste transferred from the discharge pipe 12. A door 7 is provided on one side of the collection box 6. A handle 8 is fixedly connected to the rear end of one side of the door 7. The operator can open it by pulling the handle 8. The collection box 6 has a door 7, which facilitates the removal of waste materials and maintains the normal function of the collection box 6. A blower 30 is fixedly connected to the other side of the collection box 6. The main function of the blower 30 is to generate negative pressure inside the collection box 6. This negative pressure will cause the waste materials in the discharge pipe 12 to enter the collection box 6 more smoothly. At the same time, it can also suck in some small metal shavings and dust generated during the cutting process, thereby improving the comprehensiveness of waste collection. A filter screen 28 is fixedly connected to the inner wall of the other side of the collection box 6. The filter screen 28 protects the blower 30. It prevents impurities from entering the blower 30, reduces the possibility of wear and blockage of the blower 30, extends the service life of the blower 30, and thus ensures the normal operation of the entire collection assembly.

[0038] Working principle: When the push rod motor 1 is turned on, its output drives the moving plate 3 to move. The moving plate 3 then drives the first motor 4 to move, turning on the first motor 4. The output of the first motor 4 rotates the lock housing 17, causing the cutting blade 13 to rotate and cut the tube. Sliding the sliding button 18 compresses the spring 20, removing the fixing rod 21. During removal, the fixing rod 21 presses the slider 19 into the locking hole of the sliding button 18. To replace the cutting blade 13, insert the fixing rod 21 into the lock housing 17, loosen the sliding button 18, and the spring 20 resets the sliding button 18. The reset sliding button 18 compresses the slider 19, fixing it to the fixing rod 21. This allows for quick replacement of the cutting blade 13, enabling the cutting process to be completed in a short time. Replacement significantly reduces downtime and increases overall equipment uptime, thereby improving production efficiency. It allows the cutting machine to quickly adapt to different cutting process requirements, enabling rapid replacement of different types of blades, improving equipment versatility and utilization. It reduces damage caused by improper blade handling during replacement, ensuring timely replacement of blades when they wear down to a certain extent, maintaining high precision in each cut, and improving overall product quality. Opening valve 15 allows air pump 29 to deliver compressed air from gas storage tank 2 to hose 16, which then enters vortex chamber 14. The compressed air enters vortex chamber 14, forming a high-speed rotating vortex. Due to centrifugal force, the gas separates into two parts; heavier gas molecules are pushed towards vortex chamber 14. On the outside of tube 4, lighter gas molecules gather towards the center. Due to friction and collision, air molecules undergo energy separation. High-temperature gas is discharged from hot-end tube 24, and low-temperature gas is discharged from cold-end tube 23. The low-temperature gas is blown towards the cutting blade 13 to cool it down, allowing the blade to operate within a suitable temperature range. This effectively extends the blade's lifespan, reduces the frequency of blade replacement, lowers production costs, and ensures the blade maintains a stable shape and size, thereby improving cutting accuracy and guaranteeing the quality of the cut metal square tube. This results in a smoother surface on the cut metal square tube, reducing the workload of subsequent surface treatment and improving the overall product quality. Energy consumption is relatively low. While achieving effective cooling, it also helps reduce the overall energy consumption of the cutting equipment and cools the blade. The temperature control system keeps the blade temperature within a safe range, reducing safety risks and significantly improving the safety of the area around the equipment. When the fan 30 is turned on, it generates suction, drawing the waste generated from cutting the square tube into the collection trough 11. The waste then flows from the collection trough 11 into the discharge pipe 12 and finally falls into the collection box 6. The box door 7 is opened via the handle 8 for easy waste processing and recycling. The filter screen 28 prevents impurities from damaging the fan 30, ensuring timely cleaning and collection of waste, maintaining a clean and dry workplace, and providing a safe working environment for operators. Scattered metal scrap can also damage equipment, such as entering the transmission components or electrical system, leading to equipment malfunctions. This system effectively prevents such occurrences and extends the equipment's service life.It also allows for waste recycling, reducing reliance on virgin metal materials, lowering production costs, and effectively collecting waste to prevent environmental pollution, making the cutting process more environmentally friendly. The recycling and collection device operates automatically during cutting without interfering with normal operations, helping to maintain the continuity of cutting work and thus improving overall cutting efficiency. Turning on the second motor 9 causes the output of the second motor 9 to rotate the bidirectional threaded rod 26, which in turn moves the nut assembly 27, thereby moving the fixing clamp 10 to secure the square tube. It is adaptable to square tubes of different sizes and has rubber pads on the fixing clamp 10 to prevent damage to the square tube.
