[0034] Both the base 1 and the worktable 2 are flat. The base 1 is used to support the entire tool, and a concave surface 1.2 is provided on one end of the base 1. The worktable 2 is fixed to the base 1 by a plurality of first fixing bolts 9. A part of the worktable 2 extends out above the concave surface 1.2, and the part of the worktable 2 that extends out above the concave surface 1.2 is provided with an arc-shaped edge 2.1.
[0035] The curved surface forming block 7 is provided with a connecting part 13, which is fixedly connected to the top of the workbench 2 by a plurality of second fixing bolts 11. The curved surface forming block 7 is provided with a curved side surface 7.1, the center of which coincides with the center of the curved edge 2.1, and the lower side of the curved side surface 7.1 is provided with a receiving groove 7.2 for accommodating the curtain guide rail 8.
[0036] One end of the pull rod 6 is provided with a rotating hole 6.2. The end of the pull rod 6 with the rotating hole 6.2 extends into the space between the concave surface 1.2 and the worktable 2. A rotating connecting bolt 14 is fixedly connected to the concave surface 1.2 of the base 1. The rotating connecting bolt 14 passes through the rotating hole 6.2. The pull rod 6 can rotate around the rotating connecting bolt 14. The rotation center of the pull rod 6 coincides with the center of the arc-shaped side surface 7.1.
[0037] In this embodiment, the pressure block 5 is a circular block, which is fixed to the middle of the pull rod 6 by the third fixing bolt 12. The pressure block 5 is located next to the arc-shaped side surface 7.1, and the bending of the curtain guide rail 8 is achieved by moving the pressure block 5 along the arc-shaped side surface 7.1. A cam 6.3 is provided on the lower middle part of the pull rod 6, and the center of the cam 6.3 coincides with the center of the pressure block 5. A cam groove 1.1 is provided on the concave surface 1.2 of the base 1, and the center of the cam groove 1.1 coincides with the rotation center of the pull rod 6. The cam 6.3 is located in the cam groove 1.1. When the pull rod 6 rotates, the cam 6.3 will slide along the cam groove 1.1. The cooperation between the cam 6.3 and the cam groove 1.1 makes the rotation of the pull rod 6 more stable.
[0038] The other end of the lever 6 is a handle part 6.1, which extends to the outside of the base 1. The operator can rotate the lever 6 through the handle part 6.1.
[0039] The top block assembly is located on the side of the curved forming block 7 away from the pressure block 5. The top block assembly is used to limit the position of the curtain guide rail 8 and includes a front top block 3 and a side top block 4. The front top block 3 and the side top block 4 are respectively fixed to the top of the workbench 2 by the fourth fixing bolt 10. The side top block 4 is located between the front top block 3 and the curved forming block 7. When bending, the front top block 3 is used to limit the front end of the curtain guide rail 8. The front end of the curtain guide rail 8 will be stuck on the side of the front top block 3. The curved forming block 7 and the side top block 4 abut against the two sides of the curtain guide rail 8. The front top block 3, the side top block 4 and the curved forming block 7 limit the curtain guide rail 8 and fix the curtain guide rail 8 to ensure the stability of the bending process.
[0040] like Figure 5 As shown, the shape of the shaping block 15 is adapted to the shape of the guide groove 8.1 of the curtain guide rail 8. In this embodiment, the shaping block 15 is composed of a large square and a small square. The cross-sectional shape of the guide groove 8.1 of the curtain guide rail 8 is square. The width of the groove opening 8.2 of the guide groove 8.1 is narrower than the width inside the guide groove 8.1. When the shaping block 15 is inserted into the guide groove 8.1 of the curtain guide rail 8, the large square of the shaping block 15 is located inside the guide groove 8.1, and the small square of the shaping block 15 is located at the groove opening 8.2 of the guide groove 8.1. By inserting the shaping block 15 into the guide groove 8.1 of the curtain guide rail 8, the structural strength of the curtain guide rail 8 can be strengthened, making it less likely for the guide groove 8.1 to deform when the curtain guide rail 8 is bent, thus better ensuring the bending quality.
[0041] The method of using the special tool for bending and forming the aircraft curtain guide rail in this embodiment is as follows:
[0042] Several shaping blocks 15 are inserted close together into the guide groove 8.1 of the curtain guide rail 8. The shaping blocks 15 enhance the strength of the curtain guide rail 8 and prevent the guide groove 8.1 of the curtain guide rail 8 from deforming when subjected to bending force.
[0043] like Figure 3 As shown, place the curtain guide rail 8 on the workbench 2. The front end of the curtain guide rail 8 is engaged with the side of the front top block 3. The arc-shaped forming block 7 and the side top block 4 respectively abut against the two sides of the curtain guide rail 8. Part of the curtain guide rail 8 is engaged in the receiving groove 7.2 of the arc-shaped forming block 7. The pressure block 5 and the side top block 4 are located on the same side. Then pull the pull rod 6 to make the pull rod 6 rotate around the rotating connecting bolt 14. The pressure block 5 will move along the arc-shaped side 7.1, and the cam 6.3 will move along the cam groove 1.1. With the pressure of the pull rod 6, the pressure block 5 gradually bends the curtain guide rail 8 into shape. At this time, as shown... Figure 4 As shown.
[0044] After bending is complete, loosen the pull rod 6 and remove the bent curtain guide rail 8.
