Description

Technical Field

[0001] The present application relates to the preparation of aircraft mechanical components, which belongs to the metal parts forming and processing technology, and is specifically related to a bending device for forming stringers. Background Art

[0002] A stringer is a long strip-shaped component used to enhance the strength and rigidity of the fuselage or wing in an aircraft structure. It is usually installed on the inner side of the aircraft skin and is closely connected to the skin to form an integral structure. Stringers are generally divided into fuselage stringers and wing stringers. Fuselage stringers are generally installed inside the fuselage of the aircraft and arranged along the length of the fuselage. They are mainly used to help the aircraft withstand various forces during takeoff, landing and flight. Wing stringers are generally installed inside the wing of the aircraft and arranged along the length of the wing. They are mainly used to help the wing withstand aerodynamic forces, engine thrust and the reaction force of the landing gear. In order to enable the stringers to be stably installed on the frame, the stringers are generally designed to be bent in multiple sections. When processing such stringers, it is generally necessary to bend the sheet material multiple times before it can be formed into stringers. When using conventional bending equipment to bend the sheet material to form it into stringers, it is generally necessary to load and unload the material manually, and the sheet material can only be bent at one bending point at a time. It can only be formed into stringers after multiple bendings, which is inefficient. Summary of the invention

[0036] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the implementation modes of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] like Figure 1 As shown, this embodiment provides a bending device for beam forming, including an upper working bar 1, a bending column 2, and a lower working bar 3.

[0038] Specifically, Figure 1 and Fig.11As shown, the cross-section of the upper working bar 1 is rectangular, and there are two parallel lengthwise directions. The two end surfaces of the two upper working bars 1 are coplanar and the lower surfaces are arranged in parallel. The upper working bars 1 are all arranged to move along their own width directions and height directions. The upper working bars 1 are all penetrated by a plurality of ventilation holes 11 along their own height directions. In this example, each upper working bar 1 is penetrated by four ventilation holes 11, and the ventilation holes 11 are arranged in an array along the lengthwise direction of the upper working bar 1. The upper ends of the ventilation holes 11 are connected to ventilation hoses 12, and the ventilation hoses 12 are used to be connected to the exhaust mechanism outside the equipment. The ventilation holes 11 are used to form negative pressure through the ventilation hoses 12 and the external exhaust mechanism when the lower surface of the upper working bar 1 contacts the truss plate, thereby adsorbing the truss plate. Preferably, a sealing ring can be provided at the lower end of the ventilation hole 11 to avoid air leakage when adsorbing the truss plate.

[0039] Specifically, Figure 1 As shown, the bending column 2 has two axial directions that are parallel to the length direction of the upper working bar 1, and the two end faces of the two bending columns 2 are coplanar, and two rotation axes corresponding to the bending columns 2 are defined, and the rotation axes are parallel to the axial directions of the bending columns 2 and are located above the upper working bar 1, and the rotation axes are moved along the width direction of the upper working bar 1, and the bending column 2 is rotated around the corresponding rotation axes and moves with the corresponding rotation axes, and two guide axes corresponding to the bending columns 2 are defined, and the guide axes are perpendicular to the axial directions of the bending column 2, and the guide axes rotate with the corresponding bending column 2, and the bending column 2 is moved along the corresponding guide axes, and the bending column 2 is used to push the truss plate to bend it.

[0040] Specifically, Figure 1 As shown, the lower working bar 3 has two length directions parallel to the length direction of the upper working bar 1. The lower working bars 3 correspond to the bending columns 2 one by one. The lower working bars 3 rotate with the corresponding bending columns 2. The upper surfaces of the lower working bars 3 are perpendicular to the guide axes corresponding to the corresponding bending columns 2. The lower working bars 3 are movable along their own width directions and height directions.

[0041] When working, Fig.12 Taking the beam shown in the figure as an example, the device is first installed to an external drive mechanism, which can be a crane, a slide rail, a screw rod, etc.; combined with Figure 8~Figure 10 As shown, the working process of the equipment includes: grabbing the plate, bending and forming, and placing the stringers.

[0042] When grabbing the plate, combine Figure 8As shown, an external driving mechanism is used to drive the device to the top of the plate placement, and the bending column 2 is rotated so that the bending column 2 and the lower working bar 3 are both located above the upper working bar 1. The device is driven downward so that the lower surface of the upper working bar 1 contacts the plate, and a negative pressure is formed in the vent 11 through an external extraction mechanism and a ventilation hose 12. The lower surface of the upper working bar 1 adsorbs the plate, and the device is driven upward at this time to complete the grabbing. When grabbing, the angle of the device needs to be adjusted so that the length direction of the upper working bar 1 is parallel to the length direction of the plate after grabbing the plate.

[0043] The bending process is divided into two steps; during the first bending, Fig. 9 As shown, first bend at the two bending lines near the two ends of the plate; adjust the position of the bending column 2 along the guide axis, adjust the position of the rotating axis along the width direction of the upper working bar 1, and rotate the bending column 2 around the rotating axis so that the rotated bending column 2 is respectively located under the plates outside the two bending lines, and make the guide axes parallel to the height direction of the upper working bar 1, that is, the lower surface of the lower working bar 3 is parallel to the lower surface of the upper working bar 1, adjust the position of the lower working bar 3 so that the upper surface of the lower working bar 3 is in contact with the lower surface of the plate, and the contact surfaces are both located between the two bending lines of the plate. At this time, the upper working bar 1 stops adsorbing the plate, and the plate stays on the lower working bar 3. Move the upper working bar 1 so that the opposite side edges of the lower surfaces of the two upper working bars 1 are respectively located at the two bending lines of the plate, and the plate is adsorbed by the upper working bar 1 again to further fix the plate, and move the bending column 2 upward. The bending column 2 cooperates with the upper working bar 1 to complete the first bending of the plate.

[0044] During the second bend, Fig.10 As shown, bending is performed at two bending lines close to the inner side of the plate; the rotating axis is moved along the width direction of the upper working bar 1, and the bending column 2 is moved along the guide axis so that the bending column 2 is respectively located above the plate outside the two bending lines, and the positions of the upper working bar 1 and the lower working bar 3 are adjusted so that the contact surface between the upper working bar 1 and the plate is located between the two bending lines, and the two opposite sides of the lower surfaces of the two lower working bars 3 are respectively located at the two bending lines of the plate, and the plate is adsorbed by the upper working bar 1 to further fix the plate, and the bending column 2 is moved downward, and the bending column 2 cooperates with the lower working bar 3 to complete the second bending of the plate.

[0045] When placing the beams, keep the upper working bar 1 adsorbing the plate, adjust the position of the lower working bar 3, and rotate the bending column 2 around the rotating axis so that the bending column 2 and the lower working bar 3 are both located above the upper working bar 1.
