[0030] The working principle and advantages of the present invention: When the bending device for the production and processing of the landing bracket of the aircraft is in use, the working process is as follows:
[0031] As Figures 1 to 5As shown, one end of the metal pipe to be bent is passed through between the first supporting wheel 8 and the corresponding auxiliary wheel 34, and the other end is passed through between the second supporting wheel 9 and the corresponding auxiliary wheel 34. After adjusting the position, the motor 4 is started through the controller to work. The motor 4 drives the second gear 32 to rotate through the first gear 31, and the second gear 32 drives the first screw 5 to move towards the bracket 22 through the screw drive, so that the first screw 5 drives the top wheel 7 to bend the metal pipe. When the bent part of the metal pipe touches and contacts the touch switch 30 on the bracket 22, the touch switch 30 transmits the contact signal of the metal pipe to the controller, and the controller controls the motor 4 to work in the reverse direction, so that the motor 4 drives the second gear 32 to rotate in the reverse direction through the first gear 31, and the second gear 32 drives the first screw 5 to move away from the bracket 22 and reset through the screw drive, completing the bending of the metal pipe. Then, the bent metal pipe can be taken off, and the operation is simple and convenient.
[0032] When it is necessary to adjust according to the length and bending angle of the metal pipe, the motor 12 is started through the controller to work. At this time, the motor 12 is powered on, and at the same time, the electromagnetic ring 41 is also powered on to generate a magnetic force opposite to the lower surface of the magnetic block 37, so that the magnetic block 37 compresses the spring 38 and drives the column block 40 to move upward through the push-pull rod 39. Furthermore, the column block 40 applies a pulling force to the lower end of the fifth connecting rod 46 through the fourth connecting rod 45, so that the sixth connecting rod 47 drives the pressing plate 43 and the convex rib 44 on its lower surface to move upward, so that the convex rib 44 is separated from the rib groove and does not contact, releasing the locking of the moving seat 3. While the motor 12 is working, it drives the second screw 10 to rotate, so that the second screw 10 drives the sliding seat 11 to reciprocate through the thread, and then the sliding seat 11 drives the second supporting wheel 9 to move closer to or away from the first supporting wheel 8. Since the first connecting rod 14 and the second connecting rod 16 have the same structure and cooperate with the first supporting rod 13 and the second supporting rod 15, a parallel four-bar linkage mechanism is formed on both sides of the moving seat 3, so that the central connection line of the top wheel 7, the first supporting wheel 8 and the second supporting wheel 9 is always an isosceles triangle. Then, the fastening screw 21 is loosened so that the sleeve 20 can slide on the second sliding rod 19, thereby adjusting the position of the bracket 22, realizing the adjustment according to the lengths and bending angles of different metal pipes, improving the scope of use and greatly improving the work efficiency. After the adjustment is completed, the fastening screw 21 is tightened so that the sleeve 20 cannot slide on the second sliding rod 19 to ensure the fixed position of the bracket 22. In addition, when the moving seat 3 moves horizontally to the right, it drives the first sliding plate 24 to slide to the right in the first sliding cylinder 23 through the first push-pull rod 25, so that the first sliding plate 24 squeezes the hydraulic oil in the first sliding cylinder 23 into the second sliding cylinder 27 through the conduit 26. Since the first sliding cylinder 23 and the second sliding cylinder 27 have exactly the same structure, the hydraulic oil enters the second sliding cylinder 27 and then pushes the second sliding plate 28 to move to the right through the second sliding plate 28 and the second push-pull rod 29, and the moving distances are the same. In this way, it is possible to keep the transverse distance of the top wheel 7 while synchronizing the transverse distance and direction of the bracket 22, saving time and effort.
[0033] After the adjustment is completed, the controller controls the second motor 12 to stop working, so that the second screw 10 stops rotating, and the electromagnetic ring 41 loses power and does not generate magnetic force. Thus, under the restoring force of the spring 38, the magnetic block is driven to move downward and reset, causing the magnetic block 37 to drive the column block 40 to move downward through the push-pull rod three 39. Furthermore, the column block 40 applies a pushing or pulling force to the lower end of the link five 46 through the link four 45, making the link five 46 and the link six 47 in a straight line. At this time, the link five 46 fits tightly against the inner side of the L-shaped bracket 42, and the link four 45 is perpendicular to the link five 46. Then, the link six 47 drives the pressing plate 43 to move downward, causing the convex ribs 44 to engage with the corresponding rib grooves, thereby realizing the locking of the moving seat 3 to maintain the stability of the moving seat 3 when bending the metal pipe.

An electromagnetic ring (41) is fixed to the lower end inside the third sliding cylinder (36), and the third push-pull rod (39) passes through the electromagnetic ring (41).
9. A bending device for manufacturing a landing bracket of an aircraft according to claim 8, characterized in that: Two L-shaped brackets (42) are symmetrically fixed to the lower end of the outer side wall of the third sliding cylinder (36). A fifth connecting rod (46) is hinged to the inner side of the corner of the L-shaped bracket (42). The lower end of the fifth connecting rod (46) is hinged to a pressing plate (43) through a sixth connecting rod (47). The peripheral wall of the column block (40) is hinged to the lower end of the fifth connecting rod (46) through a fourth connecting rod (45). When the fifth connecting rod (46) and the sixth connecting rod (47) are in a straight line, the fifth connecting rod (46) fits and abuts against the inner side edge of the L-shaped bracket (42), and the fourth connecting rod (45) is perpendicular to the fifth connecting rod (46).
10. A bending device for manufacturing a landing bracket of an aircraft according to claim 9, characterized in that: A ribbed groove is formed at the bottom of the arc-shaped groove (2), and the direction of the ribbed groove is perpendicular to the moving direction of the top wheel (7). A convex rib (44) is fixed to the bottom surface of the pressing plate (43), and the convex rib (44) is correspondingly engaged with the ribbed groove.
