Description

Technical Field

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

[0002] As a carrier of various spacecraft, the carrying capacity of the launch vehicle is crucial. The carrying capacity is related to the rocket structure design and the size of the rocket diameter. At present, the diameter of the launch vehicle used in aerospace is relatively large, reaching 3-6 meters, and the diameter will be larger in the future. The profile frame is an important component of the launch vehicle. At present, most of the profiles of the profile frames used in launch vehicles are semicircular, that is, bent into 180 degrees, with a diameter of 2-6 meters, and there are many types of cross-sections, most of which are asymmetric angles.

[0003] Most of the existing profiles of the profile frame are formed by vertical roll-bending equipment. For the profile bent into 180°, when the vertical roll-bending equipment bends the profile, the profile is affected by its own gravity and easily sinks because the plane where the profile is located is in a vertical state. Even if a supporting device is used for support, the quality and bending accuracy of the bending cannot be guaranteed. Therefore, the existing vertical roll-bending equipment can only roll-bend the profiles of the profile frame with a diameter of less than 4 meters to ensure the bending quality, and the profiles of the profile frame with a diameter greater than 4 meters cannot be rolled or the bending quality cannot be guaranteed.

[0004] In addition, the vertical roll bending equipment can only perform one-way bending processing on the profile. If the profile needs to be bent in the forward and reverse directions, it is necessary to manually unload the profile after one-way bending and change the direction of loading for bending. This not only increases the labor force and leads to low production efficiency, but also the re-positioning of the profile also leads to low bending accuracy of the profile.

[0005] Therefore, at this stage, it is necessary to study a bending equipment to meet the bending forming needs of large diameter profiles. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings and deficiencies in the prior art and to provide a horizontal bending device for bending large-diameter profiles. The horizontal bending device can realize the bending of large-diameter profiles, solve the problem that existing large-diameter profiles cannot be bent or have low bending quality, thereby improving the quality and bending accuracy of large-diameter profiles.

[0007] In order to achieve the above object, the present invention is implemented by the following technical scheme: a horizontal bending device for bending large-diameter profiles, comprising:

[0008] frame;

[0009] A conveying mechanism for conveying profiles;

[0010] and at least one bending and forming mechanism for bending the profile;

[0013] In the above scheme, during the profile bending process, the horizontal bending equipment of the present invention makes the profile conveying direction and the profile bending direction located in the same horizontal plane, and the horizontal plane is parallel to the end face of the frame, so that the bending forming of large-diameter profiles can be realized, and the problem that the existing large-diameter profiles are easy to sink due to their own gravity and cannot be bent or the bending quality is low, thereby improving the bending quality and bending accuracy of large-diameter profiles.

[0014] The bending and forming mechanism also includes a mounting seat, and the side roller mold core assembly is arranged on the mounting seat; the bending and forming mechanism can be movably arranged on the frame, which means that any one or more of the following three methods are adopted:

[0015] Method 1: The mounting base is movably connected to the frame along the Y-axis direction;

[0016] Method 2: The mounting base is movably connected to the frame along the X-axis direction;

[0017] Method three: The mounting base is movably connected to the frame along the Z-axis direction.

[0018] The side roller mold core assembly can be swingably arranged on the mounting seat to achieve adjustable angle of the profile bending process.

[0019] The side roller mold core assembly can be swingably arranged on the mounting seat, which means that: the bending 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 so as to drive the swing plate to swing along the guide block.

[0020] The guide block is an arc-shaped guide block;

[0021] 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.

[0024] The side 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 profile conveying station better docking, but also meet the different bending requirements of the profile, and can realize the profile twisting, that is, rotation bending along the X-axis direction or the Y-axis direction, which greatly improves 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 side pressure wheel shaft and the axis of the side shaft is perpendicular to the tangent of the contact part between the profile and the front roller or the rear roller. Therefore, the present invention can also adjust the swing angle of the side 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 side shaft is perpendicular to the tangent of the contact part between the profile and the front roller or the rear roller, the profile conveyed by the profile conveying station can smoothly enter the profile bending station for bending processing.

[0025] During the bending process, the bending radius of the profile gradually decreases and rebounds.
