Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe processing equipment, specifically a CNC machining device for hot-formed flat steel pipes. Background Technology

[0002] Steel pipes are commonly used engineering materials, often used for transporting fluids and powdery solids, exchanging heat energy, and manufacturing mechanical parts. During the production process, steel pipes need to be cut and processed into pipes of different lengths according to the different needs of users.

[0003] A search revealed a steel pipe processing device with application number 202323324946.7. This device utilizes a structural design of an electric actuator, mounting column, moving bar, fixed plate, electric slide rail, and electric slider to achieve the moving cooperation between the moving bar and the mounting column, as well as the sliding cooperation between the electric slide rail and the electric slider. This allows for the adjustment of the position of the cutting motor and the cutting blade, enabling operators to change the cutting position of the steel pipe according to the actual situation, ensuring the cutting effect of the steel pipe and improving the practicality of the processing device. However, in this device, the cutting motor, driven by the electric slider, can only move laterally along the guide rail. When the diameter of the steel pipe to be cut is larger than the radius of the cutting blade (even when cutting small-sized steel pipes, the cutting motor is prone to colliding with the steel pipe), the cutting blade cannot cut the steel pipe in one go, causing the cutting motor to be blocked by the steel pipe and unable to move, thus preventing the cutting motor from completing the cutting of the steel pipe. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a CNC machining device for hot-formed flat steel pipes to solve the technical problems mentioned above in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a CNC machining device for hot-formed steel pipes, comprising a machining table, a fixed frame connected to the top center of the machining table, a hydraulic cylinder and a guide rod provided on one side of the top of the fixed frame, a cutting machine mounted on the output end of the hydraulic cylinder and the bottom of the guide rod via a fixed plate, a first motor provided on the top of the fixed frame, a transmission gear connected to the output end of the first motor, a first driven gear connected to one side of the outer surface of the fixed frame, three second driven gears and three stabilizing frames connected to one side of the fixed frame via a sleeve shaft, and a stabilizing column connected inside the stabilizing frame, one of the stabilizing columns connected to one side of a second pulley, a second motor provided on the top of the machining table, and a first pulley connected to the output end of the second motor, with a belt connecting the first pulley and the second pulley.

[0006] Furthermore, multiple conveying rollers and a third motor are respectively installed on both sides of the top of the processing table. Each of the multiple conveying rollers is connected to a ratchet at one end, and the multiple ratchets are connected in series to form a whole by a ratchet bar.

[0007] By adopting the above technical solution, when the steel pipe enters the processing table, the operator starts the third motor through the control panel. The output end of the third motor drives the ratchet to rotate, which is transmitted through the ratchet, thereby causing the conveyor roller to rotate and transport the steel pipe to the appropriate position for processing.

[0008] Furthermore, the top of the fixed frame is equipped with a control panel, and the first motor, hydraulic cylinder, second motor, third motor and cutting machine are all electrically connected to the control panel.

[0009] By adopting the above technical solution, the staff can control the start and stop of the first motor, hydraulic cylinder, second motor, third motor and cutting machine through the control panel, thereby reducing the workload and labor intensity of the staff.

[0010] Furthermore, the first driven gear meshes with the transmission gear and the second driven gear, respectively.

[0011] By adopting the above technical solution, after the steel pipe is moved to the appropriate position, the staff turns off the third motor and starts the first motor through the control panel. The output end of the first motor drives the transmission gear to rotate. The second driven gear meshes with the transmission gear and the second driven gear respectively. Under the drive of the transmission gear, the first driven gear drives the second driven gear to rotate at a certain angle, thereby driving the stabilizer to rotate until the stabilizer column contacts the steel pipe, clamping and supporting the steel pipe.

[0012] Furthermore, the three second driven gears are arranged in a ring array.

[0013] By adopting the above technical solution, under the drive of the first driven gear, three second driven gears simultaneously drive the stabilizer to rotate around the center of the steel pipe, thereby adjusting the position of the stabilizer column, so that the stabilizer column can support steel pipes of different sizes and improve the practicality of the device.

[0014] Furthermore, the cross-section of the sleeve shaft is inverted "T" shape, and the second driven gear and the stabilizer are both rotatably connected to the fixed frame through the sleeve shaft.

[0015] By adopting the above technical solution, after the steel pipe is clamped, the operator operates the control panel to start the second motor. The output end of the second motor drives the first pulley to rotate. Through the belt transmission, the second pulley drives the stabilizing column to rotate, which in turn drives the steel pipe to rotate together. This makes it easier for the subsequent cutting machine to cut the steel pipe. The stabilizing column supports the steel pipe, preventing the steel pipe from shaking due to the stress generated by the interaction between the cutting machine and the steel pipe, which would affect the cutting accuracy of the steel pipe. At the same time, it reduces the risk of saw blade breakage.

[0016] Furthermore, the transmission gear is rotatably connected to the fixed frame.

[0017] By adopting the above technical solution, driven by the output end of the first motor, the transmission gear meshes with the first driven gear, causing the first transmission gear to drive the three second transmission gears to rotate at a certain angle, thereby driving the stabilizer to adjust the position of the stabilizer column. At the same time, in cooperation with the second motor, the stabilizer column supports the steel pipe while driving the steel pipe to rotate, thus facilitating the cutting machine to cut the steel pipe.

[0018] Furthermore, the guide rod is slidably connected to the fixing frame.

[0019] By adopting the above technical solution, when cutting steel pipes, the operator can simultaneously start the cutting machine and the hydraulic cylinder through the control panel. Guided by the guide rod, the output end of the hydraulic cylinder drives the cutting machine to move down and cut the steel pipe. When the cutting machine moves to the appropriate position, the hydraulic cylinder is turned off. By changing the position of the cutting machine in the above way, the cutting machine can cut steel pipes of different sizes, thereby improving the practicality of the device.

[0020] Furthermore, the stabilizing column is movably connected to the stabilizing frame.

[0021] By adopting the above technical solution, the first pulley rotates the second pulley through the belt driven by the output end of the second motor, thereby driving the stabilizing column to rotate. This allows the stabilizing column to clamp the steel pipe while driving the steel pipe to rotate, which facilitates subsequent cutting by the cutting machine. At the same time, the stabilizing column is cylindrical, which can reduce the frictional resistance of the stabilizing column when the steel pipe rotates while supporting the steel pipe.

[0022] Furthermore, a protective cover is connected to one side of the top of the fixing frame, and an observation window is provided on the outer surface of the protective cover.

[0023] By adopting the above technical solution, the working area of ​​the cutting machine is covered by a protective cover, thereby preventing the debris generated by the cutting machine from flying everywhere and causing injury to the surrounding workers. The observation window allows the workers to observe the production situation and easily grasp the production progress.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model is equipped with a transmission gear, a first driven gear, a second driven gear, a stabilizer frame, and a stabilizer wheel. After the steel pipe is moved to a suitable position, the operator turns off the third motor and starts the first motor through the control panel. The output end of the first motor drives the transmission gear to rotate. The first driven gear meshes with the transmission gear and the second driven gear respectively. Under the drive of the transmission gear, the first driven gear drives the second driven gear to rotate at a certain angle, thereby driving the stabilizer frame to rotate until the stabilizer column contacts the steel pipe, clamping and supporting the steel pipe. By adjusting the rotation angle of the second driven gear, the position of the stabilizer wheel can be adjusted, so that the stabilizer wheel can support steel pipes of different sizes, improving the practicality of the device.

[0026] 2. This utility model is equipped with a first pulley, a belt, and a second pulley. After the clamping block fixes the steel pipe, the operator operates the control panel to start the second motor. The output end of the second motor drives the first pulley to rotate. Through the belt, the second pulley drives the stabilizing column to rotate, so that the stabilizing column drives the steel pipe to rotate together. The stabilizing column supports the steel pipe and avoids the stress generated by the interaction when the cutting machine cuts the steel pipe, which would cause the steel pipe to shake and affect the cutting accuracy. At the same time, it reduces the risk of saw blade breakage.

[0027] 3. This utility model, by setting up a hydraulic cylinder, a first guide column, and a cutting machine, allows the operator to simultaneously start the cutting machine and the hydraulic cylinder through the control panel when cutting steel pipes. Guided by the second guide rod, the output end of the hydraulic cylinder drives the cutting machine to move down and cut the steel pipe. When the cutting machine moves to the appropriate position, the hydraulic cylinder is turned off. By changing the position of the cutting machine in the above manner, the cutting machine can cut steel pipes of different sizes, thereby improving the practicality of the device.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] The embodiments of this utility model will be described below based on its overall structure.

[0037] Example 1: A CNC machining device for hot-formed flat steel pipes, such as... Figures 1-6 As shown, the machine includes a processing table 1, with a fixed frame 2 connected to the top center of the processing table 1. A hydraulic cylinder 14 and a guide rod 15 are located on one side of the top of the fixed frame 2. A cutting machine 16 is mounted on the output end of the hydraulic cylinder 14 and the bottom of the guide rod 15 via a fixed plate. A first motor 3 is located on the top of the fixed frame 2, with a transmission gear 4 connected to the output end of the first motor 3. A first driven gear 5 is connected to one side of the outer surface of the fixed frame 2. Three second driven gears 7 and three stabilizing frames 9 are connected to one side of the fixed frame 2 via a sleeve shaft 6. A stabilizing column 10 is connected inside the stabilizing frame 9, and a second pulley 13 is connected to one side of one of the stabilizing columns 10. A second electric motor 16 is located on the top of the processing table 1. The machine 8 has a first pulley 11 connected to the output end of the second motor 8, and a belt 12 is connected between the first pulley 11 and the second pulley 13. Multiple conveyor rollers 20 and a third motor 17 are installed on the top two sides of the processing table 1, respectively. Each of the multiple conveyor rollers 20 has a ratchet 18 connected to one end, and the multiple ratchet 18 are connected in series by a ratchet 19 to form a whole. When the steel pipe enters the processing table 1, the operator starts the third motor 17 through the control panel 21. The output end of the third motor 17 drives the ratchet 18 to rotate, which is transmitted through the ratchet 19, thereby causing the conveyor rollers 20 to rotate and transport the steel pipe, so that the steel pipe enters the appropriate position for processing.

[0038] See Figure 1 , Figure 2 and Figure 6In the above embodiment, the top of the fixed frame 2 is provided with a control panel 21, and the first motor 3, hydraulic cylinder 14, second motor 8, third motor 17 and cutting machine 16 are all electrically connected to the control panel 21. The operator controls the start and stop of the first motor 3, hydraulic cylinder 14, second motor 8, third motor 17 and cutting machine 16 through the control panel 21, thereby reducing the workload of the operator and reducing the labor intensity of the operator.

[0039] See Figure 1 and Figure 2 In the above embodiment, the first driven gear 5 meshes with the transmission gear 4 and the second driven gear 7 respectively. When the steel pipe moves to the appropriate position, the operator turns off the third motor 17 and starts the first motor 3 through the control panel 21. The output end of the first motor 3 drives the transmission gear 4 to rotate. Through the first driven gear 5 meshing with the transmission gear 4 and the second driven gear 7 respectively, the first driven gear 5 drives the second driven gear 7 to rotate at a certain angle under the drive of the transmission gear 4, thereby driving the stabilizer 9 to rotate until the stabilizer column 10 contacts the steel pipe, clamping and supporting the steel pipe.

[0040] See Figure 2 In the above embodiment, the three second driven gears 7 are arranged in a circular array. Driven by the first driven gear 5, the three second driven gears 7 simultaneously drive the stabilizer 9 to rotate around the center of the steel pipe, thereby adjusting the position of the stabilizer 10 so that the stabilizer 10 can support steel pipes of different sizes and improve the practicality of the device.

[0041] See Figure 3 , Figure 4 and Figure 5 In the above embodiment, the cross-section of the sleeve shaft 6 is inverted "T" shape, and the second driven gear 7 and the stabilizer 9 are rotatably connected to the fixed frame 2 through the sleeve shaft 6. After the steel pipe is clamped, the operator operates the control panel 21 to start the second motor 8. The output end of the second motor 8 drives the first pulley 11 to rotate, which is transmitted through the belt 12, causing the second pulley 13 to drive the stabilizer column 10 to rotate, so that the stabilizer column 10 drives the steel pipe to rotate together, thereby facilitating the subsequent cutting machine 16 to cut the steel pipe. The stabilizer column 10 supports the steel pipe, avoiding the stress generated by the interaction when the cutting machine 16 cuts the steel pipe, which would cause the steel pipe to shake and affect the cutting accuracy of the steel pipe, while reducing the risk of saw blade breakage.

[0042] See Figure 2In the above embodiment, the transmission gear 4 is rotatably connected to the fixed frame 2. Driven by the output end of the first motor 3, the transmission gear 4 meshes with the first driven gear 5, causing the first transmission gear 4 to drive the three second transmission gears 4 to rotate at a certain angle, thereby driving the stabilizer 9 to adjust the position of the stabilizer column 10. At the same time, in cooperation with the second motor 8, the stabilizer column 10 supports the steel pipe while driving the steel pipe to rotate, thereby facilitating the cutting machine 16 to cut the steel pipe.

[0043] See Figure 1 and Figure 2 In the above embodiment, the guide rod 15 is slidably connected to the fixed frame 2. When cutting the steel pipe, the operator starts the cutting machine 16 and the hydraulic cylinder 14 simultaneously through the control panel 21. Guided by the guide rod 15, the output end of the hydraulic cylinder 14 drives the cutting machine 16 to move down and cut the steel pipe. When the cutting machine 16 moves to the appropriate position, the hydraulic cylinder 14 is turned off. By changing the position of the cutting machine 16 in the above manner, the cutting machine 16 can cut steel pipes of different sizes, thereby improving the practicality of the device.

[0044] See Figure 1 , Figure 2 and Figure 5 In the above embodiment, the stabilizing column 10 is movably connected to the stabilizing frame 9. Driven by the output end of the second motor 8, the first pulley 11 causes the second pulley 13 to rotate through the belt 12, thereby driving the stabilizing column 10 to rotate. This allows the stabilizing column 10 to clamp the steel pipe while driving the steel pipe to rotate, which is convenient for subsequent cutting by the cutting machine 16. At the same time, the stabilizing column 10 is cylindrical, which can reduce the frictional resistance of the stabilizing column 10 when the steel pipe rotates while supporting the steel pipe.

[0045] Example 2: To avoid burns to workers from debris generated during steel pipe cutting, Example 2 is an improvement on Example 1. (See attached document.) Figure 6 A protective cover 22 is connected to one side of the top of the fixed frame 2, and an observation window 23 is provided on the outer surface of the protective cover 22. The protective cover 22 covers the working area of ​​the cutting machine 16, thereby preventing the debris generated by the cutting machine 16 from flying everywhere when cutting the steel pipe and causing injury to the surrounding workers. The observation window 23 allows the workers to observe the production situation and easily grasp the production process.

[0046] The implementation principle of this utility model is as follows: When the steel pipe enters the processing table 1, the operator starts the third motor 17 through the control panel 21. The output end of the third motor 17 drives the ratchet 18 to rotate, which is transmitted through the ratchet 19, and multiple conveying rollers 20 rotate to transport the steel pipe. When the steel pipe moves to the appropriate position, the operator turns off the third motor 17 and starts the first motor 3 through the control panel 21. The output end of the first motor 3 drives the transmission gear 4 to rotate. Under the drive of the transmission gear 4, the first driven gear 5 drives the second driven gear 7 to rotate at a certain angle, thereby driving the stabilizer 9 to rotate until the stabilizer column 10 contacts the steel pipe, thus stabilizing the steel pipe. The pipe is clamped and supported. After the steel pipe is clamped, the operator operates the control panel 21 to start the second motor 8. The output end of the second motor 8 drives the first pulley 11 to rotate. Through the belt 12, the second pulley 13 drives the stabilizing column 10 to rotate, so that the stabilizing column 10 drives the steel pipe to rotate together. At this time, the operator simultaneously starts the cutting machine 16 and the hydraulic cylinder 14. Guided by the guide rod 15, the output end of the hydraulic cylinder 14 drives the cutting machine 16 to move down. After moving to the appropriate position, the hydraulic cylinder 14 is turned off. With the cooperation of the stabilizing column 10, the cutting machine 16 cuts the steel pipe. The cut steel pipe is transferred out of the processing table 1 by the conveyor roller 20 on the other side.
