Description

Technical Field

[0001] This application relates to the technical field of torsion straightening machines, and in particular to a torsion straightening machine for profile steel. Background Technology

[0002] During the processing of structural steel, twisting often occurs, requiring further correction using a straightening machine. Currently used twist straightening machines typically employ a combination of front and rear dies to straighten and correct twisting of the structural steel. Workers manually guide the structural steel through the rear die and straighten it using the grooves within the front die. The top of the grooves on the front die is designed to be open, while the top of the grooves on the rear die is closed. When the structural steel is twisted, a downward pressure head presses down on the structural steel within the front die, causing the rear die to rotate and deform the structural steel, thus correcting the twist. During this straightening process, the force is transmitted along the structural steel to the rear die. Since the rear die is usually made of iron, long-term stress can cause its grooves to gradually deform, making it impossible to maintain a precise groove shape and thus failing to meet production requirements.

[0003] Traditional torsion straightening machines are prone to groove deformation during use. This is mainly because during the straightening process, the force is transmitted to the rear mold through the profile steel. Although the rear mold is designed to provide structural stability, the limitations of iron materials make it difficult for it to withstand long-term continuous stress without deformation. Therefore, this deformation will gradually accumulate and eventually affect the quality and accuracy of the entire straightening process, thereby reducing the service life and production efficiency of the torsion straightening machine. Utility Model Content

[0004] To overcome the problem of groove deformation in the rear die of existing straightening machines during use, which is mainly because during the straightening process, the force is transmitted to the rear die through the profile steel. Although the rear die is designed to provide structural stability, the limitations of the iron material make it difficult for it to withstand long-term continuous stress without deformation. Therefore, this deformation gradually accumulates, eventually affecting the quality and accuracy of the entire straightening process, thereby reducing the service life and production efficiency of the straightening machine. This application provides a profile steel straightening machine.

[0005] The steel profile torsion straightening machine provided in this application adopts the following technical solution: A steel profile straightening machine includes a frame, a rear rotating block vertically fixed at one end of the top surface of the frame, and a support vertically fixed at the other end of the top surface of the frame. A front mold support block is vertically fixed on the side of the top surface of the frame near the support, and a steel profile groove is formed through the top surface of the front mold support block. A conveying component is vertically arranged on the side of the top surface of the frame near the front mold support block, and the conveying component is used to drive the steel profile to move toward the front mold support block. A rotating cylinder is horizontally inserted through the center of the rear rotating block, and the rotating cylinder is rotatably connected in the rear rotating block. A straightening through groove for the steel profile to pass through is formed through both ends of the rotating cylinder horizontally through the center of the rotating cylinder, and an inner bushing is detachably assembled in the straightening through groove of the rotating cylinder, and the inner bushing is made of copper.

[0006] By adopting the above technical solution, the frame serves as the supporting structure of the entire machine, ensuring its stability. The rear rotating block achieves straightening and twisting operations on the profile steel through a horizontally set rotating drum. The straightening and twisting groove in the center of the rotating drum is used for the profile steel to pass through, and a removable inner bushing made of copper reduces friction and extends the machine's service life. The front mold support block supports the profile steel through a through-type profile steel groove, ensuring its correct position during the straightening process. The conveyor drives the profile steel towards the front mold support block, bringing it into the straightening and twisting range. First, the conveyor delivers the profile steel to the profile steel groove in the front mold support block, and then the conveyor pushes the profile steel into the straightening and twisting groove in the rotating drum. The rear rotating block drives the rotating drum to rotate, thereby achieving the straightening and twisting of the profile steel. At the same time, the use of an inner bushing reduces the friction between the rotating drum and the profile steel, improving the accuracy and efficiency of straightening and twisting.

[0007] Optionally, rotating columns are horizontally fixed on both sides of one end face of the rotating drum, and a torsion bar is rotatably connected to the end of the rotating column away from the rotating drum, and a torsion plate is fixed to the end of the torsion bar away from the rotating column.

[0008] By adopting the above technical solution, the main function of the rotating drum is to provide a rotating platform, while the horizontally fixed rotating columns on both sides of one end face are used for quick assembly of the inner bushing later. The torsion bar is connected to the rotating column through its end away from the rotating drum and can rotate relative to it; while the end of the torsion bar away from the rotating column is fixed with a torsion plate for rotational transmission and locking of rotational force.

[0009] Optionally, both sides of one end of the inner liner are fixed with perforated plates, and a twisted groove is opened through the perforated plate, with the twisted plate passing through the twisted groove of the perforated plate.

[0010] By adopting the above technical solution, perforated plates are fixed on both sides of one end of the inner liner. The torsion groove design on the perforated plates allows the torsion plate to pass through, thereby achieving relative rotation with the inner liner. When the drum rotates, the connection between the torsion bar and the torsion plate not only transmits rotational force but also restricts the horizontal sliding of the inner liner on the drum, achieving a dual effect of rotation and fixing force. This ensures that the equipment can perform stable rotational operation while maintaining the necessary locking function. This design improves the flexibility and reliability of the equipment.

[0011] Optionally, a torsion motor is horizontally fixed on the top surface of the rear rotating block, and a torsion gear is fixed at the output end of the torsion motor.

[0012] By adopting the above technical solution, the torsion correction motor is installed on the top surface of the rear rotating block, responsible for providing rotational power. The torsion correction gear is fixedly connected to the output end of the torsion correction motor to transmit the motor's power.

[0013] Optionally, a toothed ring is fixedly fitted on the outer circumference of the rotating drum, and the toothed ring meshes with the torsion gear.

[0014] By adopting the above technical solution, the toothed ring fixedly fitted on the outer circumference of the rotating drum ensures precise meshing with the torsion-correcting gear, allowing the rotational power of the motor to be transmitted to the rotating drum through the toothed ring. Through this structural design, the torsion-correcting motor drives the torsion-correcting gear to rotate, which in turn causes the rotating drum to rotate synchronously through the meshing toothed ring, thereby enabling the adjustment of the steel material passing through the drum using a knob.

[0015] Optionally, a downward hydraulic rod is vertically fixed on the top surface of the support, and a pressure plate is horizontally fixed at the bottom output end of the downward hydraulic rod, and the pressure plate is used to compress the torsion-straightening steel.

[0016] By adopting the above technical solution, the support is used to bear and support the entire torsion correction mechanism. A downward hydraulic rod is vertically fixed on its top surface, serving as the power source. The hydraulic system controls the vertical pressure adjustment of the torsion correction steel. A pressure plate is horizontally fixed at the bottom output end of the downward hydraulic rod. The top of the pressure plate directly contacts the torsion correction steel. The piston rod of the downward hydraulic rod extends to provide horizontal pressure, ultimately achieving the compression correction of the torsion correction steel. First, under the control of the hydraulic system, the piston rod of the downward hydraulic rod extends, driving the pressure plate downward to compress the torsion correction steel. Second, by adjusting the pressure of the hydraulic system, the pressure on the torsion correction steel can be precisely controlled to ensure the correction effect.

[0017] Optionally, the conveying component includes a hole frame, which is vertically fixed on the end face of the front mold block away from the support. A drive roller is horizontally rotatably connected to the lower inner side of the hole frame. A rod frame is vertically slidably assembled on the upper inner surface of the hole frame. A pressure roller is horizontally fixed on the bottom surface of the rod frame. A downward pressure spring is vertically fixed on the top surface of the rod frame, and the top end of the downward pressure spring is fixed on the upper inner surface of the hole frame.

[0018] By adopting the above technical solution, the perforated frame in the conveyor is used to support other components and maintain their relative positions. The drive roller installed horizontally on the lower side inside is powered by a drive motor, so that the material can be smoothly pulled through the system. The vertically sliding rod on the inner top surface can move up and down in the vertical direction. The pressure roller fixed at the bottom of the rod is used to compress the material to ensure that it is spread evenly, while the downward pressure spring fixed at the top of the rod keeps the pressure roller on the material appropriate, neither too tight nor too loose.

[0019] Optionally, a drive motor is horizontally fixed on one side of the hole frame, and the output end of the drive motor is fixed to the end of the drive roller.

[0020] By adopting the above technical solution, after the drive motor starts, it drives the drive roller to rotate through its output end, thereby pulling and moving the material. At the same time, the rod moves with the material in the vertical direction and keeps the pressure roller under appropriate pressure on the material, ensuring that the material is uniformly compressed and passes through the system smoothly, thus achieving stable material conveying and compression.

[0021] In summary, this application includes at least one of the following beneficial technical effects: A copper inner bushing is inserted into the straightening groove of the rotating cylinder. The relatively soft nature of copper allows the force applied to the copper sheet to deform under pressure, preventing wear and deformation of the straightening groove over time. Simultaneously, the torsion grooves on the perforated plates on both sides of the inner bushing penetrate the torsion plate. Rotating the torsion plate causes the torsion rod to rotate on the rotating column, pressing the torsion plate against the inner bushing and fixing it in place within the straightening groove of the rotating cylinder. The inner bushing protects the straightening groove from deformation, improving the accuracy of subsequent steel straightening. Rotating the torsion plate later facilitates quick removal and replacement of the inner bushing. Attached Figure Description

Detailed Implementation

[0024] The present application will be further described in detail below with reference to the accompanying drawings.

[0025] This application discloses a steel profile torsion straightening machine. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 A steel profile straightening and twisting machine includes a frame 1. A rear rotating block 2 is vertically fixed at one end of the top surface of the frame 1, and a support 4 is vertically fixed at the other end of the top surface of the frame 1. A front mold support block 11 is vertically fixed on the side of the top surface of the frame 1 near the support 4, and a steel profile groove is formed through the top surface of the front mold support block 11. A conveying component 3 is vertically arranged on the side of the top surface of the frame 1 near the front mold support block 11, and the conveying component 3 is used to drive the steel profile to move toward the front mold support block 11. A rotating cylinder 21 is horizontally connected through the center of the rear rotating block 2, and the rotating cylinder 21 is rotatably connected in the rear rotating block 2. A straightening through groove 28 for the steel profile to pass through is formed through both ends of the rotating cylinder 21, and an inner liner 5 is detachably assembled in the straightening through groove 28 of the rotating cylinder 21, and the inner liner 5 is made of copper.

[0026] By adopting the above technical solution, the frame 1 serves as the supporting structure of the entire machine, ensuring its stability. The rear rotating block 2 achieves straightening and twisting operations on the profile steel through the horizontally set rotating drum 21. The straightening and twisting groove in the center of the rotating drum 21 is used for the profile steel to pass through, and the removable inner bushing 5, made of copper, reduces friction and extends the service life of the machine. The front mold support block 11 supports the profile steel through the through-set profile steel groove, ensuring its correct position during the straightening process. The conveyor 3 drives the profile steel towards the front mold support block 11, bringing it into the straightening and twisting range. First, the conveyor 3 sends the profile steel into the profile steel groove of the front mold support block 11, and then the conveyor 3 pushes the profile steel into the straightening and twisting groove 28 of the rotating drum 21. The rear rotating block 2 drives the rotating drum 21 to rotate, thereby achieving the straightening and twisting of the profile steel. At the same time, the use of the inner bushing 5 reduces the friction between the rotating drum 21 and the profile steel, improving the accuracy and efficiency of the straightening and twisting.

[0027] Reference Figure 3 and Figure 4A rotating cylinder 21 has horizontally fixed rotating columns 23 on both sides of one end face. A torsion bar 24 is rotatably connected to the end of the rotating column 23 away from the rotating cylinder 21, and a torsion plate 25 is fixed to the end of the torsion bar 24 away from the rotating column 23. The main function of the rotating cylinder 21 is to provide a rotating platform. The horizontally fixed rotating columns 23 on both sides of one end face are used for quick assembly of the inner bushing 5. The torsion bar 24 is connected to the rotating column 23 through its end away from the rotating cylinder 21 and can rotate relative to it. The torsion plate 25 is fixed to the end of the torsion bar 24 away from the rotating column 23 for transmitting and locking the rotational force. A perforated plate 51 is fixed to both sides of one end of the inner bushing 5, and a torsion groove is formed through the perforated plate 51. The torsion plate 25 passes through the torsion groove of the perforated plate 51. The torsion groove design on the perforated plate 51 allows the torsion plate 25 to pass through, thereby achieving relative rotation with the inner bushing 5. When the drum 21 rotates, the connection between the torsion bar 24 and the torsion plate 25 not only transmits rotational force but also restricts the horizontal sliding of the inner bushing 5 within the drum 21, achieving a dual effect of rotation and fixing force. This ensures that the equipment can rotate stably while maintaining the necessary locking function. This design improves the flexibility and reliability of the equipment.

[0028] Reference Figure 3 A torsion motor 26 is horizontally fixed on the top surface of the rear rotating block 2, and a torsion gear 27 is fixed to the output end of the torsion motor 26. The torsion motor 26 is mounted on the top surface of the rear rotating block 2 and is responsible for providing rotational power. The torsion gear 27 is fixedly connected to the output end of the torsion motor 26 to transmit the motor's power. A gear ring 22 is fixedly fitted on the outer circumference of the rotating drum 21, and the gear ring 22 meshes with the torsion gear 27. The gear ring 22 fixedly fitted on the outer circumference of the rotating drum 21 ensures precise meshing with the torsion gear 27, so that the rotational power of the motor can be transmitted to the rotating drum through the gear ring. Through this structural design, the torsion motor 26 drives the torsion gear 27 to rotate, and then the rotating drum 21 rotates synchronously through the meshing gear ring 22, thereby realizing the adjustment of the steel material passing through the drum.

[0029] Reference Figure 3A downward hydraulic rod 41 is vertically fixed to the top surface of the support 4, and a pressure plate 42 is horizontally fixed to the bottom output end of the downward hydraulic rod 41. The pressure plate 42 is used to compress the torsion-correcting steel. The support 4 is used to bear and support the entire torsion-correcting steel correction mechanism. The downward hydraulic rod 41 is vertically fixed to its top surface. The downward hydraulic rod 41 serves as a power source, and the vertical pressure of the torsion-correcting steel is adjusted and controlled through the hydraulic system. The pressure plate 42 is horizontally fixed to the bottom output end of the downward hydraulic rod 41. The top of the pressure plate 42 is in direct contact with the torsion-correcting steel. The piston rod of the downward hydraulic rod 41 extends to provide horizontal pressure, ultimately achieving the compression and correction of the torsion-correcting steel. First, through the control of the hydraulic system, the piston rod of the downward hydraulic rod 41 extends, driving the pressure plate 42 to move downward and compress the torsion-correcting steel. Second, by adjusting the pressure of the hydraulic system, the pressure on the torsion-correcting steel can be precisely controlled to ensure the correction effect.

[0030] Reference Figure 4 and Figure 5 The conveying component 3 includes a perforated frame 31, which is vertically fixed to the end face of the front mold support block 11 away from the support 4. A drive roller 32 is horizontally rotatably connected to the lower inner side of the perforated frame 31. A rod 34 is vertically slidably assembled on the upper inner surface of the perforated frame 31. A pressure roller 35 is horizontally fixed on the bottom surface of the rod 34. A downward pressure spring 36 is vertically fixed on the top surface of the rod 34, and the top of the downward pressure spring 36 is fixed to the upper inner surface of the perforated frame 31. The perforated frame 31 in the conveying component 3 is used to support other components and maintain their relative positions. The drive roller 32, which is horizontally installed on the lower inner side, is powered by a drive motor 33, so that the material can be smoothly pulled through the system. The rod 34, which slides vertically on the upper inner surface, can move up and down in the vertical direction. The pressure roller 35, which is fixed at the bottom of the rod 34, is used to compress the material to ensure that it is spread evenly, while the downward pressure spring 36, which is fixed at the top of the rod 34, keeps the pressure of the pressure roller 35 on the material appropriate, neither too tight nor too loose. A drive motor 33 is horizontally fixed to one side of the perforated frame 31, and the output end of the drive motor 33 is fixed to the end of the drive roller 32. After the drive motor 33 starts, it drives the drive roller 32 to rotate through its output end, thereby pulling and moving the material. At the same time, the rod frame 34 moves with the material in the vertical direction and keeps the pressure roller 35 under appropriate pressure on the material, ensuring that the material is uniformly compressed and passes smoothly through the system, thereby achieving stable material conveying and compression.

[0031] The implementation principle of a steel profile torsion straightening machine according to an embodiment of this application is as follows: First, the inner sleeve 5 made of copper is inserted into the straightening groove 28 of the rotating cylinder 21. Due to the relatively soft texture of copper, the force is applied to the copper sheet, causing the copper sheet to deform under pressure. This prevents the straightening groove 28 of the rotating cylinder 21 from being worn and deformed over a long period of time. At the same time, the torsion grooves on the perforated plates 51 on both sides of the inner sleeve 5 pass through the torsion plate 25. Then, the torsion plate 25 is rotated to make the torsion rod 24 rotate on the rotating column 23, so that the torsion plate 25 presses against the inner sleeve 5 and fixes it in the straightening groove 28 of the rotating cylinder 21. Rotating the torsion plate 25 later facilitates the quick removal and replacement of the inner sleeve 5. Then, when the steel section is turned, the steel section is inserted through the inner sleeve 5 in the rotating cylinder 21 of the rear rotating block 2, and then conveyed into the front mold support block 11 through the conveying component 3. Then, the downward hydraulic rod 41 on the top surface of the support 4 is extended, pushing the pressure plate 42 to press the steel section flat, thereby completing the turning and straightening of the steel section.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
