A bending device for producing nickel-based alloy aviation parts

Abstract

This invention relates to the field of metal component bending technology, specifically a bending device for the production of nickel-based alloy aerospace parts. If the pipe to be bent has a large diameter, the operator can insert an adjusting rod into the groove. The arc-shaped surface at the end of the adjusting rod will press against the arc-shaped surface of the slider inside the groove, causing the slider to move away from the center of the groove. During this movement, the slider pushes a rectangular plate away from the center of the groove, and the multiple rectangular plates move away from each other, increasing the outer dimensions of the rectangular block and allowing it to accommodate larger pipe sizes. This enables bending of pipes of different sizes. Simultaneously, before bending the pipe, both ends are aligned with the rectangular blocks on the support blocks, and then the rectangular blocks are inserted into the ends of the pipe to support the interior, preventing deformation of the pipe ends and eliminating the need for secondary correction.

Description

Technical Field

[0001] This invention relates to the field of metal component bending technology, specifically a bending device for the production of nickel-based alloy aerospace parts. Background Technology

[0002] Aviation components encompass all individually manufactured and identifiable units that make up the structure, functional systems, and equipment of aircraft (such as airplanes, helicopters, and drones).

[0003] In aircraft construction, various pipelines, like blood vessels, crisscross the fuselage, connecting precision components and providing fuel, gas, electromechanical or hydraulic power to ensure flight safety and lifespan. The sheet metal in aerospace components is bent to form specific shapes and structures to meet the needs of different parts of the aircraft. For example, structural components such as the skin, wing spars, and frames of an aircraft may need to be manufactured through bending processes.

[0004] In existing processes for bending pipes used in aircraft, some of these pipes have thin walls. When using a bending machine or pipe bending machine to bend the pipes, the deformation between the structures during bending can change the shape of the pipe ends. This alters the shape of the pipe ends before installation, making it difficult to install the bent pipes directly. The pipe ends need to be calibrated before installation, which reduces work efficiency.

[0005] In summary, to solve the technical problems raised in this paper, this invention proposes a bending device for the production of nickel-based alloy aerospace parts. Summary of the Invention

[0010] There are two limiting posts, which are symmetrically arranged on both sides of the slide rail, and the gap between the two limiting posts is greater than the diameter of the pressure block.

[0011] There are two fixed columns, which are symmetrically arranged on the upper part of the machine body on both sides of the slide rail. The two fixed columns are rotatably connected to the upper part of the machine body. The gap between the two fixed columns is greater than the gap between the two limiting columns, and the fixed columns are located between the pressure block and the limiting columns.

[0012] A folding telescopic rod is installed on the outer surface of a fixed column, and a support block is rotatably connected to the upper end of the folding telescopic rod away from the fixed column. A rectangular block is provided on the side of the support block.

[0013] As a preferred embodiment of this application, each face of the rectangular block is provided with a rectangular groove, and a rectangular plate is slidably connected inside the rectangular groove. A sliding groove is provided on the inner wall of the rectangular groove, and a column groove is provided in the middle of the rectangular block. The column groove is connected to the sliding groove, and a slider is slidably connected inside the sliding groove. One end of the slider is connected to the rectangular plate, and the other end is located in the column groove. The end face of the slider in the column groove is set with an arc surface. An adjusting rod is slidably connected in the column groove. The size of the adjusting rod is the same as the size of the column groove. The end of the adjusting rod located inside the column groove is set with an arc surface, and the adjusting rod can be removed from the column groove.

[0014] As a preferred embodiment of this application, a cylindrical block is fixed to the other end face of the support block, and the included angle between the cylindrical block and the rectangular block is degrees.

[0015] As a preferred embodiment of this application, a plurality of arc-shaped grooves are evenly provided on the outer side of the cylindrical block, and an arc-shaped plate is slidably connected inside the arc-shaped groove. A second sliding groove is provided on the inner wall of the arc-shaped groove. A second column groove is provided in the middle of the cylindrical block, and the second sliding groove is connected to the second column groove. The size of the second column groove is the same as that of the first column groove. A second slider is slidably connected inside the second sliding groove. One end of the second slider is connected to the arc-shaped plate, and the other end is located in the second column groove. The end of the second slider located in the second column groove is set with an arc surface.

[0016] As a preferred embodiment of this application, an adjustment block is provided at one end of the limiting plate near the pressure block, and multiple adjustment grooves are provided on the arc surface of the pressure block, the size of the adjustment grooves being the same as the size of the adjustment block.

[0017] As a preferred embodiment of this application, each of the limiting plates has multiple strip plates on its inner side, the strip plates are distributed on the limiting plate, and the limiting plate is in close contact with the arc surface of the pressure block; the pressure block has multiple rectangular through holes, each rectangular through hole is located between adjacent strip plates; and the strip plates on the two limiting plates are staggered.

[0020] The beneficial effects of this invention are as follows:

[0021] If the pipe diameter to be bent is large, the worker can insert an adjusting rod into the groove. As the rod is inserted, the curved end of the rod presses against the curved surface of the slider inside the groove, causing it to move away from the center of the groove. This movement pushes the rectangular plate away from the center of the groove, increasing the overall size of the rectangular block and allowing it to accommodate larger pipes. This enables bending of pipes of different sizes. Before bending, the pipe ends are aligned with the rectangular blocks on the support blocks, which are then inserted into the pipe ends to support the interior, preventing deformation of the pipe ends and eliminating the need for secondary correction.

Detailed Implementation

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] Example 1:

[0032] like Figures 1 to 7 As shown; a bending device for producing nickel-based alloy aerospace parts, the bending device includes a pressure bending machine, the pressure bending machine includes a body 1; the body 1 includes:

[0033] The slide rail 11 is located at the upper middle part of the body 1, and a mounting base is slidably connected to the slide rail 11;

[0034] The telescopic device 12 is provided at the end of the slide rail 11, and the output end of the telescopic device 12 is connected to the mounting base.

[0035] The pressure block 13 is semi-circular and is mounted on the mounting base; limit plates 131 are provided on the upper and lower sides of its arc-shaped surface; the limit plates 131 are arc-shaped structures.

[0036] There are two limiting posts 14, and the two limiting posts 14 are symmetrically arranged on both sides of the slide rail 11, and the gap between the two limiting posts 14 is greater than the diameter of the pressure block 13.

[0037] There are two fixed columns 15, which are symmetrically arranged on the upper end of the body 1 on both sides of the slide rail 11. The two fixed columns 15 are rotatably connected to the upper end of the body 1, and at the same time, the fixed columns 15 are slidably connected to the upper end of the body 1. The gap between the two fixed columns 15 is greater than the gap between the two limiting columns 14, and the fixed columns 15 are located between the pressure block 13 and the limiting columns 14.

[0038] A folding telescopic rod 151 is provided on the outer surface of the fixed column 15, and a support block 152 is rotatably connected to the upper end of the folding telescopic rod 151 away from the fixed column 15. A rectangular block 153 is provided on the side of the support block 152.

[0039] Each face of the rectangular block 153 has a rectangular groove 154. A rectangular plate 155 is slidably connected inside the rectangular groove 154. A sliding groove 156 is formed on the inner wall of the rectangular groove 154. A column groove 157 is formed in the middle of the rectangular block 153. The column groove 157 is connected to the sliding groove 156. A slider 158 is slidably connected inside the sliding groove 156. One end of the slider 158 is connected to the rectangular plate 155, and the other end is located in the column groove 157. The end face of the slider 158 in the column groove 157 is set with an arc surface. An adjusting rod 159 is slidably connected in the column groove 157. The size of the adjusting rod 159 is the same as the size of the column groove 157. The end of the adjusting rod 159 located inside the column groove 157 is set with an arc surface, and the adjusting rod 159 can be removed from the column groove 157.

[0040] A cylindrical block 16 is fixed to the other end face of the support block 152, and the included angle between the cylindrical block 16 and the rectangular block 153 is 90 degrees.

[0041] A metal sleeve 141 is fitted on the outside of the limiting post 14, and the metal sleeve 141 is slidably connected to the limiting post 14.

[0042] The specific work process is as follows;

[0043] When in use, the worker holds the steel pipe and then compresses and extends the folding telescopic rod 151 according to the length of the pipe. The folding telescopic rod 151 is composed of multiple folded tubes. Then, the two ends of the pipe are aligned with the rectangular blocks 153 on the support block 152, and the rectangular blocks 153 are inserted into the two ends of the pipe to support the inside of the pipe. After the pipe is installed, the pipe is located between the pressure block 13 and the two limiting posts 14. Then, the worker activates the telescopic device 12, which is a hydraulic telescopic cylinder in the prior art. After the telescopic device 12 is activated, it pushes the mounting base closer to the limiting posts 14. The pressure block 13 on the mounting base moves closer to the telescopic post as well. During this process, the arc surface on the pressure block 13 contacts the pipe, and the pipe moves away from the extension post. One side of the telescopic device 12 contacts the surface of the limiting post 14. As the telescopic device 12 continues to compress, the two sides of the tube are limited by the limiting post 14, while the middle of the tube is compressed by the pressure block 13 and bends. After the tube bends, the two ends of the tube are no longer perpendicular to the slide rail 11, and the distance between the two ends of the tube decreases, causing the folding telescopic rod 151 to extend and retract. During the process, the fixed post 15 rotates on the machine body 1 and slides on the machine body 1 at the same time; satisfying the movement state of the two ends of the tube when the tube is bent; causing the tube to rotate along the arc surface of the pressure block 13, thereby achieving the bending of the tube; and during this process, the tube ends are supported by the rectangular block 153, thereby preventing the tube ends from deforming, thus eliminating the need for secondary correction of the tube ends after bending, and improving production efficiency;

[0044] If the pipe diameter to be bent is large, the operator can insert the adjusting rod 159 into the groove 157. As the adjusting rod 159 is inserted into the groove 157, the arc-shaped surface at the end of the adjusting rod 159 presses against the arc-shaped surface of the slider 158 inside the groove 157. This causes the slider 158 to slide within the groove 156, moving it away from the center of the groove 156. During this movement, the slider 158 pushes the rectangular plate 155 away from the center of the groove 157. The multiple rectangular plates 155 move away from each other, increasing the external dimensions of the rectangular block 153, allowing the rectangular block 153 to accommodate larger pipe sizes. This enables bending of pipes of different sizes.

[0045] Furthermore, by sleeved with a metal sleeve 141 on the outside of the limiting post 14, the metal sleeve 141 is slidably connected to the limiting post 14. When the pipe is limited by the limiting post 14, the middle part of the pipe bends. During this process, the pipe will rub against the limiting post 14. At this time, the metal sleeve 141 contacts the pipe and rotates, thereby reducing the wear caused by the limiting post 14 to the pipe when it is bent.

[0046] Furthermore, by setting a cylindrical block 16 on the other end face of the support block 152, when bending the cylindrical tube, the worker can rotate the support block 152 to align the cylindrical blocks 16 on the two support blocks 152 with each other. Then, the worker can insert the cylindrical block 16 into the cylindrical tube and bend it in the same way as the rectangular tube mentioned above, thereby enabling the bending of tubes with different structures.

[0047] Example 2:

[0048] like Figures 1 to 7 As shown; a plurality of arc-shaped grooves 161 are evenly provided on the outer side of the cylindrical block 16, and an arc-shaped plate 162 is slidably connected inside the arc-shaped groove 161. A second sliding groove 163 is provided on the inner wall of the arc-shaped groove 161; a second column groove 164 is provided in the middle of the cylindrical block 16, and the second sliding groove 163 communicates with the second column groove 164, and the size of the second column groove 164 is the same as the size of the first column groove 157; a second slider 165 is slidably connected inside the second sliding groove 163, one end of the second slider 165 is connected to the arc-shaped plate 162, and the other end is located in the second column groove 164, and the end of the second slider 165 located in the second column groove 164 is set with an arc surface;

[0049] The specific workflow is as follows;

[0050] Based on the above embodiment one, when it is necessary to process a large circular tube, the worker pulls out the adjusting rod 159 in the rectangular block 153, and then inserts the adjusting rod 159 into the column groove 164. After the adjusting rod 159 is inserted into the column groove 164, the slider 165 in the column groove 164 is squeezed by the arc-shaped end face of the adjusting rod 159 and moves away from the center of the column groove 164. During the process, the slider 165 pushes the arc plate 162, and the arc plate 162 extends out from the arc groove 161, thereby increasing the size of the cylindrical block 16, so that the cylindrical block 16 can adapt to the bending of circular tubes of different sizes, thereby improving practicality.

[0051] Example 3:

[0052] like Figures 1 to 7 As shown; an adjusting block 132 is provided at one end of the limiting plate 131 near the pressure block 13, and multiple adjusting grooves 133 are provided on the arc surface of the pressure block 13, the size of the adjusting grooves 133 being the same as the size of the adjusting block 132;

[0053] Each of the limiting plates 131 has multiple strip plates 135 on its inner side. The strip plates 135 are distributed on the limiting plate 131, and the limiting plate 131 is in close contact with the arc surface of the pressure block 13. The pressure block 13 has multiple rectangular through holes 136, each rectangular through hole 136 is located between adjacent strip plates 135, and the strip plates 135 on the two limiting plates 131 are distributed in an alternating manner.

[0054] The specific workflow is as follows;

[0055] Based on the above embodiment, an adjusting block 132 is provided at one end of the limiting plate 131 near the pressure block 13, and multiple adjusting grooves 133 are provided on the arc surface of the pressure block 13. The multiple adjusting grooves 133 are distributed vertically on the pressure block 13. If the size of the bent rectangular pipe is large, the limiting plate 131 is then removed from the pressure block 13. Specifically, the adjusting block 132 on the limiting plate 131 is removed from the inside of the adjusting groove 133, and then the adjusting groove 133 is inserted into the non-adjusting groove 133 away from the pressure block 13, so that the distance between the two limiting plates 131 increases, thereby enabling the gap between the two limiting plates 131 to accommodate larger pipes.

[0056] Similarly, when limiting a smaller rectangular tube, the limiting plate 131 and the adjusting block 132 are inserted into the adjusting groove 133 near the middle of the pressure block 13; this reduces the gap between the two limiting plates 131, which is used to limit the smaller rectangular tube.

[0057] Strip plates 135 are evenly arranged on the limiting plate 131, and rectangular through holes 136 are opened on the limiting plate 131 between each strip plate 135. The strip plates 135 on the two limiting plates 131 are staggered, so that the strip plates 135 between the two limiting plates 131 interlock and form a complete plate. The adjusting groove 133 is closed, so that when the pipe is bent, the edge of the adjusting groove 133 will not affect the outer wall of the pipe. On the other hand, when it is necessary to replace the rectangular pipe of different sizes, the two... When the limiting plates 131 are adjusted, the strip plates 135 between the two limiting plates 131 will separate from each other, causing the metal debris adhering to the strip plates 135 to fall off (metal debris will fall off the surface when the metal pipe is bent), without the need for additional cleaning; and when the two limiting plates 131 approach each other, the strip plates 135 extend out from the corresponding rectangular through holes 136, and both ends of the strip plates 135 between the two limiting plates 131 extend out from the rectangular through holes 136 between the two limiting plates 131 respectively; thus realizing that the two limiting plates 131 approach each other and satisfying the condition for the two limiting plates 131 to approach each other.

[0058] Example 4:

[0059] like Figures 1 to 7 As shown; two fixing plates 137 are provided on both sides of the flat end face of the pressure block 13. Each fixing plate 137 is rotatably connected to an arc-shaped block 138. The arc of the arc-shaped block 138 is the same as the arc of the limiting plate 131. When the two arc-shaped blocks 138 are in contact with the outer side of the limiting plate 131, the two arc-shaped blocks 138 are in contact with the middle of the limiting plate 131. Each arc-shaped block 138 is provided with an arc-shaped groove 139. When the two arc-shaped blocks 138 are in contact, the arc-shaped grooves 139 on the two arc-shaped blocks 138 form a complete groove.

[0060] The specific workflow is as follows;

[0061] Fixing plates 137 are provided on both sides parallel to the end face of the pressure block 13, and arc-shaped blocks 138 are transferred and connected on the fixing plates 137 so that the curvature of the arc-shaped blocks 138 is the same as the curvature of the limiting plate 131. When it is necessary to bend the round tubular material, the operator rotates the arc-shaped blocks 138 so that the arc-shaped blocks 138 rotate and adhere to the outside of the limiting plate 131 until the two arc-shaped blocks 138 are completely adhered to the outside of the limiting plate 131. After that, the two arc-shaped blocks 138 form a complete arc-shaped block 138, and the flow is... The two arc-shaped blocks 138 are locked together by locking parts. The arc-shaped grooves 139 on the arc-shaped blocks 138 form a complete arc-shaped groove 139, so that the inner wall of the arc-shaped groove 139 can support the outer wall of the cylindrical tube. When the rectangular tube is bent, the rectangular cavity inside the limiting plate 131 limits the tube. When the cylindrical tube is bent, the inner wall of the arc-shaped groove 139 limits the tube. Thus, it can adapt to the processing of tubes with different shapes.

[0062] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
