Description

Technical Field

[0001] This utility model relates to the field of efficient straightening mechanisms for welded pipes, and more specifically, to an efficient straightening mechanism applicable to welded pipes of various specifications. Background Technology

[0002] Welded pipes are steel pipes made by rolling steel plates or strips into round, square, or other shapes and then joining the seams using welding processes (such as electric arc welding or resistance welding). The raw material is steel plate or strip, and the production process is simple and efficient, but the strength is generally lower than that of seamless steel pipes.

[0003] In the field of welded pipe processing, the straightening process is the core link to ensure the straightness and surface quality of the pipe. Traditional straightening mechanisms mostly use roller sets with fixed spacing to apply pressure to the welded pipe at a single point. The adjustment of the roller spacing depends on manual operation, resulting in low adjustment accuracy and long time consumption. In addition, traditional mechanisms lack self-locking function, and the roller sets are prone to displacement due to vibration during the straightening process, resulting in a high rate of secondary bending of the pipe.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a high-efficiency straightening mechanism applicable to welded pipes of various specifications, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A high-efficiency straightening mechanism suitable for welded pipes of various specifications includes a welded pipe high-efficiency straightening frame, a straightening adjustment and installation component is provided inside the welded pipe high-efficiency straightening frame, a self-locking component after adjustment is provided on one side of the straightening adjustment and installation component, and a welded pipe pressing component is provided above the straightening adjustment and installation component;

[0008] To achieve the straightening and adjustment installation function, the straightening and adjustment installation assembly includes a straightening and adjustment mounting frame, which is symmetrically slidably fitted inside the welded pipe high-efficiency straightening frame. A straightening and adjustment roller is movably connected inside the straightening and adjustment mounting frame, and a drive motor is connected to one end of the straightening and adjustment roller. An adjusting threaded rod is threaded inside the straightening and adjustment mounting frame, and the adjusting threaded rod is movably connected to the straightening and adjustment mounting frame through a bearing. A connecting plate is connected to one side of the welded pipe high-efficiency straightening frame, and a distance scale plate is connected above the connecting plate.

[0009] Furthermore, the adjusting threaded rod is formed by symmetrically splicing two threaded rods.

[0010] Furthermore, a control switch is installed on one side of the high-efficiency straightening frame for welded pipes, and the drive motor is electrically connected to the outside through the control switch.

[0011] Furthermore, in order to achieve the purpose of straightening and adjusting the installation, the self-locking assembly after adjustment includes a transmission worm gear, a transmission worm meshing on one side of the transmission worm gear, a worm fixing plate movably connected to the periphery of the transmission worm, the worm fixing plate being connected to the welded pipe high-efficiency straightening frame, and an adjusting motor connected to one end of the transmission worm.

[0012] Furthermore, the motor is adjusted to be electrically connected to an external source via a control switch.

[0013] Furthermore, in order to achieve the effect of pressing down the welded pipe, the welded pipe pressing assembly includes a pressing mounting frame, which is connected to the welded pipe high-efficiency straightening frame. A pressing electric push rod is installed inside the pressing mounting frame, and a pressing moving arc plate is connected below the pressing electric push rod.

[0014] Furthermore, the downward-pressing electric actuator is electrically connected to an external source via a control switch.

[0015] The beneficial effects of this utility model are as follows:

[0016] (1) This utility model has made improvements to the existing technology. In actual use, by using the straightening adjustment installation component and the self-locking component after adjustment, it solves the problem that the traditional straightening mechanism mostly uses a fixed-spacing roller group to apply pressure to the welded pipe at a single point. The roller spacing adjustment depends on manual operation, resulting in low adjustment accuracy and long time consumption. It also solves the problem that the traditional mechanism lacks self-locking function and the roller group is prone to displacement due to vibration during the straightening process, resulting in a high secondary bending rate of the pipe.

[0017] (2) In actual use, the motor drives the transmission worm to rotate, which in turn drives the transmission worm wheel and the adjusting threaded rod to rotate. After the adjustment is completed, the self-locking characteristic of the worm wheel meshing structure can prevent the adjusting threaded rod from rotating in the opposite direction due to vibration or load, thus ensuring that the position of the correction and adjustment mounting bracket is fixed.

[0025] 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.

[0026] According to an embodiment of the present invention, a high-efficiency straightening mechanism suitable for welded pipes of various specifications is provided, including a welded pipe high-efficiency straightening frame 1, a straightening adjustment and installation component 2 is provided inside the welded pipe high-efficiency straightening frame 1, an adjustment self-locking component 3 is provided on one side of the straightening adjustment and installation component 2, and a welded pipe pressing component 4 is provided above the straightening adjustment and installation component 2.

[0027] like Figure 1-4As shown in the figure, the high-efficiency straightening mechanism applicable to welded pipes of various specifications according to the embodiment of this utility model includes a straightening adjustment mounting assembly 2 comprising a straightening adjustment mounting frame 201. The straightening adjustment mounting frame 201 is symmetrically and slidably fitted inside the high-efficiency straightening frame 1 for welded pipes. A straightening installation roller 202 is movably connected inside the straightening adjustment mounting frame 201. A drive motor 203 is connected to one end of the straightening installation roller 202. An adjusting threaded rod 204 is threadedly fitted inside the straightening adjustment mounting frame 201. The adjusting threaded rod 204 is movably connected to the straightening adjustment mounting frame 201 through a bearing 205. A connecting plate 206 is connected to one side of the high-efficiency straightening frame 1 for welded pipes. A distance scale plate 207 is connected above the connecting plate 206. The adjusting threaded rod 204 is formed by symmetrically splicing two threaded rods. A control switch 5 is installed on one side of the high-efficiency straightening frame 1 for welded pipes. The drive motor 203 is electrically connected to the outside through the control switch 5.

[0028] Through the above technical solution, the straightening and adjusting mounting frame 201 is symmetrically arranged on the internal sliding track of the welded pipe high-efficiency straightening frame 1, and is driven to move horizontally by the adjusting threaded rod 204. The straightening mounting roller 202 is movably connected inside the straightening and adjusting mounting frame 201 and is driven to rotate by the drive motor 203 through a coupling. The adjusting threaded rod 204 is composed of two symmetrical threaded rods spliced ​​together, and is threadedly engaged with the straightening and adjusting mounting frame 201 through the bearing 205 to achieve bidirectional synchronous adjustment.

[0029] like Figure 1-4 As shown, the high-efficiency straightening mechanism applicable to welded pipes of various specifications according to the embodiment of this utility model includes a self-locking assembly 3 after adjustment, comprising a transmission worm gear 301, a transmission worm 302 meshing on one side of the transmission worm gear 301, a worm fixing plate 303 movably connected to the periphery of the transmission worm 302, the worm fixing plate 303 being connected to the high-efficiency straightening frame 1 of welded pipe, and an adjustment motor 304 connected to one end of the transmission worm 302, the adjustment motor 304 being electrically connected to the outside via a control switch 5.

[0030] Through the above technical solution, the transmission worm gear 301 is fixed to the end of the adjusting threaded rod 204 and meshes with the transmission worm 302. The transmission worm 302 is driven by the adjusting motor 304 and is axially fixed to the welded pipe high-efficiency straightening frame 1 through the worm fixing plate 303.

[0031] like Figure 1-4 As shown, according to an embodiment of the present invention, a high-efficiency straightening mechanism applicable to welded pipes of various specifications is provided. The welded pipe pressing assembly 4 includes a pressing mounting frame 401, which is connected to the high-efficiency straightening frame 1. A pressing electric push rod 402 is installed inside the pressing mounting frame 401, and a pressing moving arc plate 403 is connected below the pressing electric push rod 402. The pressing electric push rod 402 is electrically connected to the outside via a control switch 5.

[0032] With the above technical solution, the pressing mounting bracket 401 is fixed to the top of the welded pipe high-efficiency straightening frame 1, and the pressing electric push rod 402 is installed inside. The pressing moving arc plate 403 moves vertically through the pressing electric push rod 402, and the arc surface adapts to the outer diameter of the welded pipe. The control switch 5 is integrated on the side of the welded pipe high-efficiency straightening frame 1, and controls the drive motor 203, the adjustment motor 304, and the pressing electric push rod 402 through the circuit.

[0033] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0034] In summary, with the help of the above-mentioned technical solution of this utility model, when the rotating adjustment threaded rod 204 is rotated, its symmetrical thread drives the two sides of the straightening and adjusting mounting bracket 201 to move synchronously in the opposite direction along the sliding track of the welded pipe high-efficiency straightening bracket 1.

[0035] The distance scale plate 207 is fixed on the connecting plate 206. The scale value is related to the rotation angle of the adjusting threaded rod 204. The operator can directly read the distance between the two straightening installation rollers 202 and quickly match the welded pipe specifications.

[0036] The drive motor 203 drives the straightening and mounting rollers 202 to rotate at high speed via a coupling, applying circumferential friction force to the surface of the welded pipe. The multi-roller linkage eliminates bending stress. Figure 1 The trajectory of the welded pipe.

[0037] The adjustment motor 304 drives the transmission worm 302 to rotate, which in turn drives the transmission worm wheel 301 and the adjusting threaded rod 204 to rotate. After the adjustment is completed, the self-locking characteristic of the worm wheel meshing structure can prevent the adjusting threaded rod 204 from rotating in the opposite direction due to vibration or load, ensuring that the position of the correction and adjustment mounting bracket 201 is fixed.

[0038] The worm gear fixing plate 303 is connected to the side wall of the welded pipe high-efficiency straightening frame 1 by bolts, which restricts the axial movement of the transmission worm gear 302.

[0039] After the control switch 5 is activated, the downward electric push rod 402 pushes the downward moving arc plate 403 to press down vertically, so that the welded pipe is tightly attached to the straightening installation roller 202, preventing the welded pipe from jumping during the straightening process. The downward moving arc plate 403 has a certain elasticity to adapt to welded pipes of various specifications.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
