Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipe bending, in particular to an adjustable heat exchange pipe bending device. BACKGROUND

[0002] The aviation pipeline plays a very key role in the operation of the aircraft, and undertakes the heavy task of transporting various fluids such as fuel, lubricating oil, hydraulic oil, oxygen, etc., and is the "lifeline" to ensure the normal operation of the aircraft system. According to the difference of the transported fluid, the aviation pipeline can be divided into fuel system pipeline, oil system pipeline, hydraulic system pipeline, oxygen system pipeline and other categories. These pipeline systems are usually composed of a closed channel by a pipe, a joint, a pipe nut, a sleeve, a seal, a pipe clamp and other components to ensure the stable flow of fluid and effective energy transfer.

[0003] In the field of aviation, various types of pipelines need to be accurately bent according to the complex spatial layout and system operation requirements of the aircraft interior to successfully complete the fluid transportation task. For example, the fuel pipeline of the aircraft engine needs to accurately transport fuel from the fuel tank to the combustion chamber, and the pipeline route needs to closely match the structure and installation position of the engine, which cannot be achieved without precise bending of the pipeline. For example, the hydraulic system pipeline needs to ensure that the hydraulic oil is stably transported to various execution components under high pressure, and also needs to be bent to reasonably layout the pipeline. The existing patent CN118976807B discloses a pipe bending device for pipe processing, which can complete bending operation for some pipelines, but when facing the complex bending requirements of aviation pipelines, especially for spiral state pipeline bending with special space trajectory requirements, the device has great limitations and cannot meet the bending requirements of complex shapes of aviation pipelines, which may cause problems such as difficult pipeline installation, poor sealing, poor fluid transportation, etc., thereby affecting the safety performance and operation stability of the aircraft.

Figure 10 The middle pipe is consistent, and then under the drive of the flipping motor 128, the flipping gear 129 matches the outer ring 117 of the bearing, thereby driving the flipping ring 115 to flip. In this way, the feeding pipe 200 held by the second guide wheel 114 and the first guide wheel 112 will flip, thereby obtaining the second section of bending on different planes. right Figure 9 When the pipe is bent, the feeding base 101 is moved to the outer end of the bent strip 315 by the position adjustment component. Then, the guide wheel component works to make the end of the feeding pipe 200 extend to the pipe end clamping mechanism 317 and be clamped and locked. Then, driven by the bending motor 319, the bending gear 303 and the bending tooth ring 308 cooperate to drive the bending disc 307 to rotate and obtain bending power. At the same time, driven by the horizontal motor 118, the horizontal screw 119 and the horizontal screw sleeve rotate relative to each other. Under the action of the thread, the feeding seat 123 slides along the horizontal guide rod 122, so that the feeding pipe 200 bends along the spiral groove 316 on the surface of the flip ring 115, thereby forming a spiral pipe. When the above three bending radii need to be adjusted, simply adjust the radial position of the bent strip 315 on the bending disc 307 through the bending diameter adjustment mechanism to adjust the bending radius of the cylindrical structure. Driven by the radial adjustment motor 323, the worm 321 and worm wheel 320 are matched, thereby driving the central shaft 327 to rotate.
