Description

Technical Field

[0001] This utility model relates to the field of steel pipe bending equipment technology, and in particular to a transverse movement device in the lower mold groove for bending and forming straight seam steel pipes. Background Technology

[0002] Straight seam steel pipe is a type of steel pipe in which the weld seam is parallel to the longitudinal direction of the pipe. It is typically classified into metric welded steel pipe, welded thin-walled pipe, transformer cooling oil pipe, etc. In actual production, bending operations are often required for the steel pipe. Steel pipe bending machines directly bend the steel pipe, and the resulting bends, compared to using pre-made bends, are not only faster to process but also reduce the number of joints and prevent leaks.

[0003] Patent specification CN210098681U discloses a lower die retraction mold for a bending machine, including a die base. Multiple rectangular strips are integrally formed on the upper end of the die base. A lower die, with an L-shaped design, is placed on the upper end of the die base. A side die is slidably connected to one side of the lower die. A connecting rod with a common clearance fits between the side die and the lower die. Anti-detachment blocks are welded to both ends of the connecting rod. A positioning sleeve with a clearance fits onto the connecting rod is welded to the die base. This utility model, through its movable side die design, can increase or decrease the distance between the side dies, better meeting the actual processing needs of steel pipes and making the use of the lower die of the bending machine more convenient. A pushing mechanism drives the movable head to move, and the two movable sleeves move away from each other, keeping the lower die and side die tightly connected and ensuring the stability of the lower die during use.

[0004] However, in implementing the relevant technology, the following problems were found in the lower die of the bending machine designed above: Although the existing technology can be adjusted according to the processing material, the processing process still requires manual feeding and pushing. Therefore, multiple pushing or picking is required during the processing, which affects the processing efficiency. In view of this, a transverse movement device in the lower die groove of straight seam steel pipe bending and forming is provided to overcome the above defects. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a transverse movement device in the lower mold groove for bending and forming straight seam steel pipes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a transverse movement device in the lower mold groove for bending and forming straight seam steel pipe, including a mold groove, with pads provided on both sides inside the mold groove, and a placement groove opened at the bottom inside the mold groove, and a transverse movement mechanism provided inside the placement groove;

[0007] The transverse movement mechanism includes a lifting plate, which is slidably connected inside the placement groove. A lifting hydraulic cylinder is connected to the bottom end of the lifting plate. A micro motor is embedded in the axial outer wall of the lifting plate, and a rotating shaft is connected to the power output end of the micro motor. A micro push rod is fixed to the end of the rotating shaft away from the micro motor, and a clamping plate is connected to the power output end of the micro push rod. A limit rod is fixed to the outer wall of the clamping plate away from the micro push rod, and a transverse movement roller is sleeved on the outside of the limit rod. A through hole is opened on the inner wall of the transverse movement roller corresponding to the position of the limit rod. The clamping plate is driven by the micro push rod, allowing the limit rod to pass into the transverse movement roller. The appropriate size is adjusted according to the required steel pipe diameter to limit the movement and prevent it from rolling off. At the same time, the power of the micro motor causes the clamping plate to drive the limit rod, so that the transverse movement roller can feed the material.

[0008] As a further description of the above technical solution: the limiting rod forms a sliding structure with the through hole through a micro push rod, and the size of the through hole matches the size of the limiting rod. The cross-section of the limiting rod and the through hole is rectangular, which facilitates the clamping plate to drive the transverse roller to rotate through the limiting rod.

[0009] As a further description of the above technical solution: the clamping plate forms a rotating structure with the lifting plate through the rotating shaft and the micro motor, and the lifting plate forms a sliding structure with the mounting groove through the lifting hydraulic cylinder. The clamping plate is rotated by the rotating shaft through the power of the micro motor. Another set of clamping plates not connected to the micro motor is fixedly engaged with the outer wall of the other axis of the lifting plate by the rotating shaft.

[0010] As a further description of the above technical solution: an installation groove is provided on one side of the bottom placement groove inside the mold groove, and a conveying mechanism is provided inside the installation groove. The placement groove facilitates the placement of the conveying mechanism and places it on the axis with the transverse movement mechanism, which facilitates the conveying of the steel pipe.

[0011] As a further description of the above technical solution: the conveying mechanism includes a mounting shell, which is inserted into the interior of the mounting groove, and a conveying roller is rotatably connected to the inner wall of the mounting shell. A cleaning pad is sleeved on the outside of the conveying roller. The conveying roller supports the steel pipe to improve the smoothness of the transmission, while the cleaning pad facilitates the wiping away of adsorbed dust and other substances.

[0012] As a further description of the above technical solution: the conveying mechanism also includes permanent magnet blocks, which are fixedly installed on both sides of the bottom end of the mounting shell. An electromagnet is embedded in the bottom of the mounting groove corresponding to the position of the permanent magnet blocks, and a damping spring is embedded on one side of the electromagnet in the bottom of the mounting groove. The damping spring gives the mounting shell a certain degree of shock absorption, thereby giving the conveying roller a certain degree of shock absorption.

[0013] As a further description of the above technical solution: the electromagnet has a U-shaped structure, and the electromagnet and the permanent magnet are magnetically attracted to each other. When the electromagnet is energized, it is magnetically attracted to the permanent magnet, which facilitates the disassembly and assembly of the conveying mechanism.

[0014] This utility model has the following beneficial effects:

[0015] The transverse movement device in the lower mold groove for straight seam steel pipe bending and forming designed in this utility model first pushes the corresponding clamping plate through two sets of miniature push rods, so that the limiting rod passes through the through hole into the transverse movement roller. The limit rod is adjusted according to the diameter of the steel pipe to further limit the steel pipe. With the rotation power of the miniature motor, the rotating shaft drives the clamping plate to rotate, so that the transverse movement roller pushes the steel pipe to move laterally. This avoids the inconvenience of manual support or handling during processing, which affects the processing efficiency. After processing is completed, the lifting plate is lifted by the lifting hydraulic cylinder, so that the steel pipe passes through the pad plate for easy handling.

[0016] The present invention designs a transverse movement device in the lower mold groove for straight seam steel pipe bending and forming. The mounting shell is connected by multiple sets of conveying rollers through rotation, which improves the smoothness of the steel pipe transverse movement process. At the same time, it is equipped with a cleaning pad to facilitate the adsorption and wiping of dust and other dust to keep it clean. The mounting shell is magnetically connected by an electromagnet and a permanent magnet, so as to disassemble and assemble it for easy cleaning of the cleaning pad. Attached Figure Description

[0023] Reference Figure 1-4The present invention provides a transverse movement device in the lower mold groove for bending and forming straight seam steel pipe: including a mold groove 1, with pads 2 provided on both sides inside the mold groove 1, a placement groove 3 opened at the bottom inside the mold groove 1, and a transverse movement mechanism 4 provided inside the placement groove 3;

[0024] The lateral movement mechanism 4 includes a lifting plate 408, which is slidably connected inside the mounting groove 3. A lifting hydraulic cylinder 409 is connected to the bottom end of the lifting plate 408. A micro motor 407 is embedded in the axial outer wall of the lifting plate 408. A rotating shaft 406 is connected to the power output end of the micro motor 407. A micro push rod 404 is fixed to the end of the rotating shaft 406 away from the micro motor 407. A clamping plate 403 is connected to the power output end of the micro push rod 404. The clamping plate 403 is located away from the outer edge of the micro push rod 404. A limiting rod 402 is fixed to the wall, and a transverse roller 401 is sleeved on the outside of the limiting rod 402. A through hole 405 is opened on the inner wall of the transverse roller 401 corresponding to the position of the limiting rod 402. The clamping plate 403 is driven by the micro push rod 404 to allow the limiting rod 402 to pass into the transverse roller 401. The size is adjusted according to the required steel pipe diameter to limit the movement and prevent it from rolling off. At the same time, the clamping plate 403 is driven by the power of the micro motor 407 to drive the limiting rod 402, so that the transverse roller 401 feeds the material.

[0025] As a further implementation of the above technical solution: the limiting rod 402 forms a sliding structure with the through hole 405 through the micro push rod 404. The size of the through hole 405 matches the size of the limiting rod 402. The cross-sections of the limiting rod 402 and the through hole 405 are rectangular, which makes it easier for the clamping plate 403 to drive the transverse roller 401 to rotate through the limiting rod 402.

[0026] As a further implementation of the above technical solution: the clamping plate 403 forms a rotating structure with the lifting plate 408 through the rotating shaft 406 and the micro motor 407. The lifting plate 408 forms a sliding structure with the mounting groove 3 through the lifting hydraulic cylinder 409. The clamping plate 403 is driven to rotate by the rotating shaft 406 through the power of the micro motor 407. Another set of clamping plates 403 not connected to the micro motor 407 is rotated and engaged with the other axial outer wall of the lifting plate 408 by the fixed rotating shaft 406.

[0027] In practice, firstly, based on the diameter of the steel pipe, the miniature push rod 404 pushes the clamping plate 403, allowing the limiting rod 402 to slide along the through hole 405 within the transverse roller 401, adjusting the steel pipe to fit the diameter, thus effectively limiting the movement and ensuring accurate positioning of the steel pipe's stepping displacement. This also prevents the steel pipe from tipping over or rolling. Subsequently, the miniature motor 407 drives the rotating shaft 406 to rotate one set of clamping plates 403. Simultaneously, another set of clamping plates 403, following the power, is rotatably connected to the lifting plate 408 axially via the rotating shaft 406. This rotation of the clamping plates 403 and the transverse roller 401 allows for transverse stepping feeding of the steel pipe, eliminating the need for manual support. After processing, the lifting hydraulic cylinder 409 activates to lift the lifting plate 408, thus removing the steel pipe from the pad 2 for easy handling by workers.

[0028] As a further implementation of the above technical solution: an installation groove 5 is provided on one side of the bottom placement groove 3 inside the mold groove 1. The installation groove 5 is equipped with a conveying mechanism 6. The placement groove 3 facilitates the placement of the conveying mechanism 6 and places it on the axis with the transverse movement mechanism 4, which facilitates the conveying of the steel pipe.

[0029] As a further implementation of the above technical solution: the conveying mechanism 6 includes a mounting shell 602, which is inserted into the interior of the mounting groove 5. The inner wall of the mounting shell 602 is rotatably connected to a conveying roller 601, and a cleaning pad 603 is sleeved on the outside of the conveying roller 601. The conveying roller 601 supports the steel pipe to improve the smoothness of the transmission, while the cleaning pad 603 facilitates the wiping away of adsorbed dust and other substances.

[0030] As a further implementation of the above technical solution: the conveying mechanism 6 also includes a permanent magnet block 604, which is fixedly installed on both sides of the bottom end of the mounting shell 602. An electromagnet 605 is embedded in the bottom of the mounting groove 5 corresponding to the position of the permanent magnet block 604. A damping spring 606 is embedded on one side of the electromagnet 605 at the bottom of the mounting groove 5. The damping spring 606 gives the mounting shell 602 a certain degree of shock absorption, thereby giving the conveying roller 601 a certain degree of shock absorption.

[0031] As a further implementation of the above technical solution: the electromagnet 605 has a U-shaped structure. The electromagnet 605 and the permanent magnet block 604 are magnetically attracted. After the electromagnet 605 is energized, it is magnetically attracted to the permanent magnet block 604, which facilitates the disassembly and assembly of the conveying mechanism 6.

[0032] In practice, the mounting shell 602 is magnetically attracted to the electromagnet 605 via the permanent magnet 604 and fixed in the mounting groove 5. The opening and closing of the electromagnet 605 facilitates the disassembly and assembly of the conveying mechanism 6. The mounting shell 602 is rotatably connected to multiple sets of conveying rollers 601, which facilitates the smoothness of steel pipe conveying. At the same time, the cleaning pad 603 facilitates wiping and scraping off the adsorbed dust, and the damping spring 606 gives the mounting shell 602 a certain degree of shock absorption.
