[0013] The present invention also provides a method for bending interior trim panels for aircraft cabins, including the bending device for interior trim panels for aircraft cabins as described above, comprising the following steps:

[0014] Step 1: The interior panel material is placed on the rotating box, and two bending support plates support both ends of the interior panel material respectively;

[0015] Step 2: The first hydraulic telescopic rod drives the first bracket to move down, so that the first rotating shaft drives the first toothed plate to move down. The first toothed plate drives the prism to move down through the gear differential, so that the auxiliary spring pressing component presses and fixes the interior panel material.

[0016] Step 3: One end of the interior panel material is bent by the single-sided bending mechanism. After one end of the interior panel material is bent, the first hydraulic telescopic rod drives the first bracket and the first rotating shaft to move down continuously. Through the design of the rotation linkage component, the first bracket drives the fixed sleeve and the rotating box to rotate 180 degrees through the second toothed plate, so that the other end of the interior panel material that needs to be bent moves to one side of the single-sided bending mechanism.

[0017] Step 4: Position the rotating box at this time using the locking and fixing mechanism, and then perform a second bending of the interior panel material by the single-sided bending mechanism;

[0018] Step 5: After the two ends of the interior panel material are bent, the first hydraulic telescopic rod drives the first bracket to move upward so that the first bracket returns to its initial height. This allows the rotating box to rotate and return to its initial position. At the same time, the auxiliary spring-loaded component releases its pressure on the interior panel material, and the processed interior panel material is removed.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] (1) The interior panel material is placed on the rotating box. Two bending support plates support both ends of the interior panel material. The first hydraulic telescopic rod drives the first bracket to move down, so that the first rotating shaft drives the first toothed plate to move down. The first toothed plate drives the prism to move down through the gear differential, so that the auxiliary spring pressing component presses and fixes the interior panel material. At this time, one end of the interior panel material is bent by the single-sided bending mechanism. After the bending of one end of the interior panel material is completed, the first hydraulic telescopic rod drives the first bracket and the first rotating shaft to continue to move down. Through the design of the rotation linkage component, the first bracket drives the fixing sleeve and the rotating box through the second toothed plate. Rotate 180 degrees to move the other end of the interior panel material that needs to be bent to one side of the single-sided bending mechanism. The position of the rotating box is then positioned by the locking and fixing mechanism. The single-sided bending mechanism then performs a second bend on the interior panel material. After both ends of the interior panel material are bent, the first hydraulic telescopic rod drives the first bracket to move upward so that the first bracket returns to its initial height. This allows the rotating box to rotate and return to its initial position. At the same time, the auxiliary spring-loaded component releases the pressure and fixation on the interior panel material, and the processed interior panel material can be removed. There is no need to repeatedly clamp and fix the interior panel material, which makes it simple and convenient to complete the bending of both ends of the interior panel material.

[0021] (2) One end of the protrusion is inserted into the corresponding groove. Through the cooperation of the protrusion and the groove, the rotating box is fixed relative to the drive box. When the rotating box rotates relative to the drive box, the protrusion slides out from the groove. The first compression spring is in a compressed state. After the rotating box rotates 180 degrees, the protrusion moves to one side of the corresponding groove. The first compression spring pushes the protrusion to move so that one end of the protrusion is inserted into the groove, which can fix the rotating box relative to the drive box and reduce the possibility of the rotating box shaking relative to the drive box during the bending process.

[0022] (3) After one end of the interior panel material is bent, as the first bracket continues to move down, the second toothed plate and the first gear mesh, the second toothed plate drives the first gear to rotate, the first gear drives the first bevel gear to rotate through the second shaft, the first bevel gear drives the third shaft and the first sprocket to rotate through the second bevel gear, the first sprocket drives the second sprocket and the fixed sleeve to rotate through the chain, and when the first bracket moves down, the rotating box can rotate relative to the drive box;

[0023] (4) When the prism moves down, the movable seat and the top plate move down. When the interior panel material is placed on the rotating box, the movable seat drives the pressing block to press the top of the interior panel material. As the prism continues to move down, the gap between the top plate and the movable seat becomes smaller. The second compression spring is in a compressed state. Through the elastic force of the second compression spring, the pressing block presses the interior panel material elastically so that the interior panel material is fixed on the rotating box. When the first tooth plate moves down, the first tooth plate drives the second gear to rotate. The second gear drives the third gear to rotate through the fourth rotating shaft. The third gear drives the prism to move down through the third tooth plate. By setting the transmission ratio between the first tooth plate, the second gear, the third gear and the third tooth plate, the difference in the rate of descent between the first tooth plate and the prism can be adjusted. Through the design of the limit strip, the second fixing block and the limit groove, the third tooth plate moves smoothly in the vertical direction. Through the design of the first fixing plate, the guide groove and the guide block, the first tooth plate moves smoothly in the vertical direction.

[0024] (5) Manually drive the fixed plate away from the third support, the tension spring is in the tension state, one end of the insert rod disengages from the slot, releasing the restriction on the position of the threaded sleeve, manually drive the threaded sleeve to rotate, change the length of the screw inside the threaded sleeve, and thus adjust the initial distance between the bending support plate and the rotating box. This can adjust the support point of the interior panel material that needs to be bent. After adjustment, release the fixed plate, the tension spring drives the fixed plate and the insert rod to move, and one end of the insert rod is inserted into the corresponding slot so that the threaded sleeve is fixed relative to the rotating box. The second hydraulic telescopic rod drives the bending pressing plate to move down, and the interior panel material is bent by the bending pressing plate. The second support is driven to move horizontally by the third hydraulic telescopic rod, which can change the position of the second hydraulic telescopic rod and the bending pressing plate. The design of the guide plate increases the stability of the second support when moving horizontally. Attached Figure Description

After one end of the interior panel material is bent, the first hydraulic telescopic rod 8 drives the first bracket 7 and the first rotating shaft 6 to move down continuously. Through the design of the rotation linkage component, the first bracket 7 drives the fixed sleeve 9 and the rotating box 2 to rotate 180 degrees through the second toothed plate 10, so that the other end of the interior panel material that needs to be bent moves to one side of the single-sided bending mechanism.

[0050] Step 4: Position the rotating box 2 at this time through the locking and fixing mechanism, and then perform a second bending of the interior panel material by the single-sided bending mechanism;

[0051] Step 5: After the two ends of the interior panel material are bent, the first hydraulic telescopic rod 8 drives the first bracket 7 to move upward so that the first bracket 7 returns to its initial height.

A method of bending an interior panel member for use in an aircraft cabin using the apparatus of claim 1, comprising the steps of: positioning the interior panel member in the first bending station; and rotating the interior panel member about the first bending axis to bend the interior panel member. Includes the following steps: Step 1: The interior panel material is placed on the rotating box (2), and the two ends of the interior panel material are supported by two bending support plates (3); Step 2: The first hydraulic telescopic rod (8) drives the first bracket (7) to move down, so that the first rotating shaft (6) drives the first toothed plate (5) to move down. The first toothed plate (5) drives the prism (4) to move down through the gear differential, so that the auxiliary spring pressing part presses and fixes the interior panel material. Step 3: One end of the interior panel material is bent by the single-sided bending mechanism. After the bending of one end of the interior panel material is completed, the first hydraulic telescopic rod (8) drives the first bracket (7) and the first rotating shaft (6) to continue to move down. Through the design of the rotation linkage component, the first bracket (7) drives the fixed sleeve (9) and the rotating box (2) to rotate 180 degrees through the second toothed plate (10) so that the other end of the interior panel material that needs to be bent moves to one side of the single-sided bending mechanism.
