Description

Technical Field

[0001] The invention relates to the technical field of bending, and more particularly to a large-diameter profile bending and forming mechanism. Background Art

[0002] At present, metal profiles with a certain amount of bending are widely used in production and life, especially in the aerospace field, automobile industry, bridges, construction and other industries.

[0003] Generally speaking, most of the existing profiles are rolled using existing conventional rolling machines, and most of the existing rolling machines adopt a vertical structure. When bending the profile, the vertical rolling machine uses the relative position change and rotational movement of the working rollers to cause the profile to undergo continuous plastic deformation to obtain a profile workpiece of a predetermined shape. However, the plane where the vertical rolling machine bends the profile is in a vertical state. For large-diameter profiles, the large-diameter profiles are prone to sinking due to the influence of their own gravity. Even if supported by a supporting device, the quality and accuracy of the bending cannot be guaranteed. Therefore, the existing vertical rolling machine can only roll and bend profiles with a diameter of less than 4 meters to ensure the bending quality, while profiles with a diameter greater than 4 meters cannot be rolled and formed or the bending quality cannot be guaranteed.

[0004] In addition, the vertical rolling machine can only bend the profile in the same direction. If the profile needs to be bent in both directions, two loading processes are required. This processing method is troublesome, time-consuming and labor-intensive, and it is necessary to repeatedly adjust the placement angle of the profile to make the bent profile meet the design requirements. The accuracy of the transition position of the positive and negative arcs cannot be guaranteed, which affects the processing quality and accuracy of the profile. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings and deficiencies in the prior art and to provide a large-diameter profile bending and forming mechanism, which can solve the problem that large-diameter profiles cannot be rolled or the bending quality cannot be guaranteed during bending processing, and can realize the bending and forming of large-diameter profiles, thereby improving the quality of large-diameter profile bending processing.

[0006] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical scheme: a large-diameter profile bending and forming mechanism, characterized in that: it is docked with a profile conveying mechanism, and the large-diameter profile bending and forming mechanism includes a frame and a roller mold core assembly; the roller mold core assembly is provided with a profile bending station through which the profile passes, and the roller mold core assembly can be movably arranged on the frame, so that the profile bending station is docked with the conveying station of the profile conveying mechanism, and the profile on the profile bending station can be bent and formed; the profile conveying direction of the profile conveying mechanism and the profile bending direction of the roller mold core assembly are located in the same horizontal plane.

[0007] In the above scheme, the bending direction of the bending forming mechanism of the present invention is in the same horizontal plane as the direction of profile conveying, and the horizontal plane is parallel to the end face of the frame, which can solve the problem that the existing large-diameter profiles are easy to sink due to their own gravity and cannot be bent or have low bending quality, and realize the bending forming of large-diameter profiles, thereby improving the quality and bending accuracy of the bending forming of large-diameter profiles. In addition, before the profile is bent, the roller mold core assembly can be movably set on the frame to adjust the profile bending station, so that the profile bending station is docked with the conveying station of the profile conveying mechanism.

[0008] The roller mold core assembly is arranged on the side of the profile conveying mechanism, and the roller mold core assembly can be movably arranged on the frame, so that the profiles in the profile bending station can be bent forward and / or reversely. In the process of profile bending, since the bending direction of the profile by the bending forming mechanism is on the same horizontal plane as the profile conveying direction, the profile bending process is not limited by space. The roller mold core assembly can bend the profile positioned in the material bending station forward and / or reversely, which can solve the problem that the bending processing space of the vertical structure rolling bending machine is limited and can only be unidirectional, so there is no need to load and unload the profile multiple times, and there is no need to repeatedly adjust the placement position of the profile multiple times, which can realize the one-time bending of the profile, greatly improving the quality, bending accuracy and bending efficiency of the profile bending.

[0009] The large-diameter profile bending and forming mechanism also includes a mounting seat, and the roller mold core assembly is arranged on the mounting seat; the roller mold core assembly can be movably arranged on the frame, which means that any one or more of the following three methods are adopted: Method 1: The mounting base is movably connected to the frame along the Y-axis direction; Method 2: The mounting base is movably connected to the frame along the X-axis direction; Method three: The mounting base is movably connected to the frame along the Z-axis direction.

[0010] The roller mold core assembly can be swingably arranged on the mounting seat to achieve adjustable angle of the profile bending process.

[0011] The roller mold core assembly can be swingably arranged on the mounting seat, which means that: the large-diameter profile bending and forming mechanism also includes a swing driving member, a transmission member, a swing plate and a guide block; the guide block is connected to the mounting seat, the side roller mold core assembly is arranged on the swing plate, and the swing plate is connected to the transmission member; the swing driving member is connected to the transmission member to drive the transmission member to move to drive the swing plate to swing along the guide block.

[0012] The guide block is an arc-shaped guide block; The transmission component includes a connecting rod and a sliding block; the sliding block is slidably connected to the guide block, and the swing plate is arranged on the sliding block; one end of the connecting rod is connected to the swing driving member, and the other end is hinged to the sliding block, and the swing driving member drives the sliding block to swing along the guide block to drive the swing plate to swing.

[0013] The roller mold core assembly includes a roller mold core bracket, a roller mold core, a shaft body and a pressure wheel module; the shaft body is installed on the roller mold core bracket through bearing 1, and the roller mold core is passed through the shaft body; the pressure wheel module is provided with a pressure wheel, and is arranged on the shaft body through bearing 2; the area between the pressure wheel and the roller mold core serves as a profile bending station.

[0014] The profile bending station is matched with the profile cross section; when the profile is bent, the pressing wheel and the roller mold core are in contact with the profile and rotate along with the profile conveying.

[0015] The pressure wheel module also includes a mounting block, a threaded rod, a locking nut, a locking piece, a connecting block and a pressure wheel shaft; the mounting block is arranged on the shaft body through a second bearing; the pressure wheel is adjustably connected to the pressure wheel shaft through a third bearing and is locked through a locking piece to achieve adjustment of the pressure wheel in the axial direction of the pressure wheel shaft; the pressure wheel shaft is adjustably connected to one end of the threaded rod through a connecting block and is locked through a locking nut to achieve adjustable distance between the pressure wheel and the roller mold core; the other end of the threaded rod is connected to the mounting block.

[0016] The roller mold core assembly of the present invention can adjust the swing angle of the profile bending station, which can not only make the profile bending station and the conveying station of the profile conveying mechanism better docking, but also can meet the different bending requirements of the profile, realize the profile twisting, that is, rotation bending along the X-axis direction or the Y-axis direction, greatly improving the practicality of the profile bending. In addition, during the profile bending process, it is necessary to ensure that the line connecting the axis of the pressure wheel shaft and the axis of the shaft body is perpendicular to the tangent of the contact part between the profile and the profile conveying mechanism. Therefore, the present invention can also adjust the swing angle of the roller mold core assembly so that the profile bending station is opposite to the profile conveying station. When the line connecting the axis of the pressure wheel shaft and the axis of the shaft body is perpendicular to the tangent of the contact part between the profile and the profile conveying mechanism, the profile conveyed by the profile conveying station can smoothly enter the profile bending station for bending processing.

[0017] During the bending process, the bending radius of the profile gradually decreases and rebounds. The pressure wheel is designed as a follow-up structure, which can move with the change of the profile radius at any time to ensure smooth movement of the profile during the rolling bending process. In addition, the distance between the pressure wheel and the roller mold core of the present invention is adjustable, and the pressure wheel is adjusted along the axial direction of the pressure wheel shaft, which can improve the bending of profiles of different thicknesses, greatly improving versatility and practicality.
