Description

Technical Field

[0001] This utility model belongs to the field of aviation manufacturing technology and relates to an aircraft spring bending device. Background Technology

[0002] Aircraft springs come in various specifications, with different sizes, thicknesses, and bending angles. Since bending is the final step, it is difficult and has a high scrap rate. Current technology mostly involves manual selection of appropriate wrenches and general-purpose tools, which results in low bending efficiency and a high scrap rate. Utility Model Content

[0003] This invention provides an aircraft spring sheet bending device that can bend copper spring sheets within a range of 0-180 degrees.

[0004] The present invention adopts the following technical solution:

[0005] An aircraft spring bending device, the bending device comprising a wrench crossbar 1, a handle vertical bar 2, a base plate 3, and a positioning pin 4.

[0006] The base plate 3 has several round holes. The number and position of the round holes are determined according to the shape of the bent spring copper sheet, i.e. the bending part, for the insertion of the positioning pin 4. The two are interference fit, and the outer diameter of the positioning pin 4 is determined according to the inner diameter of the bent part of the bent spring copper sheet.

[0007] The handle vertical rod 2 is cylindrical in shape, with a wrench horizontal rod 1 fixedly connected to its upper end for rotating the handle vertical rod 2. A positioning hole is located at the center of the lower end of the handle vertical rod 2 for cooperating with the positioning pin 4 to achieve center positioning and alignment. A cylindrical protrusion is made next to the positioning hole, and a gap is left between the cylindrical protrusion and the positioning hole. The size of the gap is set according to the thickness of the spring copper sheet, and the height of the cylindrical protrusion is set according to the width of the spring copper sheet.

[0008] In use, install the positioning pin 4 at the first round hole on the base plate 3, attach the first bend of the spring copper sheet to the positioning pin 4, align the positioning hole of the handle vertical rod 2 with the positioning pin 4 and insert it for center positioning and alignment. At this time, the spring copper sheet is sandwiched between the positioning pin 4 and the cylindrical protrusion at the lower end of the handle vertical rod 2. Twist the handle horizontal rod 1 by hand to bend the first bend of the spring copper sheet to the required angle. Keeping the position of the spring copper sheet still, install the positioning pin 4 at the second round hole on the base plate 3, attach the second bend of the spring copper sheet to the positioning pin 4, insert the handle vertical rod 2 again and twist it, and the first bend of the spring copper sheet is bent into shape. Repeat the operation to complete the final shaping of the spring copper sheet.

[0009] The beneficial effects of this utility model are: the structure of this utility model is simple and practical, and it is highly practical compared to the prior art that relies solely on manual selection of corresponding wrenches and general tools. At the same time, it can improve the bending efficiency of various aircraft spring copper plates and reduce the scrap rate of aircraft spring copper plates caused by bending.
