Description

Technical Field

[0001] This invention relates to the field of metal foil processing and manufacturing technology, and specifically to a metal honeycomb core fin forming device. Background Technology

[0002] Metal honeycomb is a type of I-beam-like material with a hexagonal pore structure. It has high specific strength, specific stiffness, and excellent heat and sound insulation properties, and is widely used in aviation, aerospace, high-speed trains and other fields.

[0003] Currently, there are two main methods for processing metal honeycomb core fins: stamping and roll forming. Stamping is inefficient and prone to breakage and tearing during foil processing. Roll forming, for example, is a processing device for tracked chain roll forming disclosed in Chinese invention patent CN102794352A. It uses a sprocket to drive the chain to roll, and each chain link is equipped with a toothed bar. The toothed bar engages to roll metal foil to form the fins. This device has a complex structure, requires high precision in the processing of sprockets, chains, and toothed bars, and has the disadvantages of difficult maintenance and high cost.

[0004] Therefore, there is a need for a metal honeycomb core fin forming device that is simple in structure, easy to implement, and low in cost. Summary of the Invention

[0005] To address the technical problems of low efficiency, easy breakage and tearing, high cost, difficult maintenance, and low product precision caused by the complex structure of the equipment when processing metal honeycomb core fins using traditional methods, this invention discloses a metal honeycomb core fin forming device, the forming device comprising:

[0006] A molded gear structure includes a drive shaft and a driven shaft disposed on a support frame. A first molded gear is fixed on the drive shaft, and a second molded gear that cooperates with the first molded gear is fixed on the driven shaft.

[0007] An adjusting gear structure is provided, comprising a differential gear and a driven adjusting gear that mesh with each other, wherein the differential gear is fixed on the drive shaft and the driven adjusting gear is fixed on the driven shaft;

[0008] A guide channel is provided on the support frame and is located between the first forming gear and the second forming gear;

[0009] A power source, which is connected to the drive shaft, is used to drive the drive shaft to rotate.

[0010] The working principle of the forming device is as follows: Metal foil is introduced through a guide channel into the space between the first and second forming gears of the forming gear structure with adjusted clearance. A power source drives the drive shaft to rotate, causing the first forming gear and the differential gear to rotate synchronously. The differential gear drives the driven adjusting gear meshing with it to rotate, which in turn drives the driven shaft to rotate, thus causing the second forming gear to rotate. Through the synchronous rotation of the first and second forming gears, the metal foil is roll-formed into metal honeycomb core fins, which are then led out through the guide channel. The design of the adjusting gear structure allows for adjustment and control of the rotational clearance between the first and second forming gears, better ensuring the consistency of foil deformation.

[0011] Furthermore, the differential gear includes an adjusting differential gear and a fixed differential gear, both of which are fixed on the drive shaft. Both the adjusting differential gear and the fixed differential gear mesh with the driven adjusting gear, and the fixed differential gear is provided with an adjusting screw.

[0012] Furthermore, the molded gear structure also includes two support structures disposed on the support frame;

[0014] Furthermore, both the angular contact ball bearing support structure and the tapered roller bearing structure include a bearing, a bearing housing, and two dustproof rings. The bearing is disposed within the bearing housing, the dustproof rings are coaxial with the bearing, and the two dustproof rings are respectively located on both sides of the bearing housing.

[0015] Furthermore, the molding apparatus further includes:

[0016] Two forming gear gap adjustment structures are provided. Each forming gear gap adjustment structure includes a first adjustment shim. The first adjustment shim is disposed between the bearing seat of the drive shaft and the bearing seat of the driven shaft in the forming gear structure. The forming gear gap adjustment structure is used to adjust the gap between the first forming gear and the second forming gear.

[0017] Furthermore, each of the molded gear clearance adjustment structures also includes a clamping structure disposed on the support frame;

[0018] The clamping structure includes a clamping block, a clamping beam, a clamping screw, and a locking handle. The clamping beam is fixed to the upper end of the support frame. The middle part of the clamping beam has a threaded hole through which the clamping screw passes. The upper end of the clamping screw has the locking handle. The lower end of the clamping screw is connected to the clamping block. The clamping block is connected to the bearing seat.

[0019] Preferably, a lifting beam is also provided between the pressing beams of the two forming gear gap adjustment structures, and the lifting beam is fixed to the support frame by bolts.

[0020] Preferably, the clamping structure further includes a second adjusting pad, which is disposed between the bearing seat of the driven shaft and the support frame.

[0021] Furthermore, limiting rings are provided on both sides of the first molded gear, and the diameter of the limiting rings is larger than the diameter of the first molded gear. The limiting rings are located outside the guide channel.

[0022] Furthermore, the power source includes a geared motor, which is mounted on a geared motor base. The output end of the geared motor is connected to the drive shaft via a coupling, and the input end of the geared motor is connected to a servo motor.

[0041] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0042] The following specific examples illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. This application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be noted that, in the absence of conflict, the following embodiments and features of the embodiments can be combined with each other. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] This invention provides a metal honeycomb core fin forming device, see [link to device]. Figure 1As shown, the molding device includes a support frame 1, a molding gear structure, an adjusting gear structure 4, a guide channel 15, and a power source 11. The molding gear structure is located inside the support frame 1. The adjusting gear structure 4 is connected to the molding gear structure and located outside the support frame 1. The guide channel 15 is located on the support frame 1. The power source 11 is located on a geared motor base 111 fixed on the support frame 1, and the power source 11 is connected to the drive shaft 37 of the molding gear structure.

[0044] Among them, see Figure 2 As shown, the forming gear structure includes a drive shaft 37 and a driven shaft 93 disposed on the support frame 1. A first forming gear 34 is fixed on the drive shaft 37, and a second forming gear 95 that cooperates with the first forming gear 34 is fixed on the driven shaft 93.

[0045] See Figure 2 and Figure 3 As shown, the adjusting gear structure 4 includes a differential gear and a driven adjusting gear 49 that mesh with each other. The differential gear is fixed on the drive shaft 37, and the driven adjusting gear 49 is fixed on the driven shaft 93 via an adjusting gear bushing 7. The guide channel 15 is disposed on the support frame 1, and the guide channel 15 is located between the first forming gear 34 and the second forming gear 95. The power source 11 is connected to the drive shaft 37 and is used to drive the drive shaft 37 to rotate.

[0046] The working principle of the forming device is as follows: Metal foil is introduced from the guide channel 15 into the space between the first forming gear 34 and the second forming gear 95 of the forming gear structure with adjusted gap. The power source 11 drives the drive shaft 37 to rotate. The first forming gear 34 and the differential gear rotate synchronously. The differential gear drives the driven adjusting gear 49, which meshes with it, to rotate. When the driven adjusting gear 49 rotates, it drives the driven shaft 93 to rotate, thereby causing the second forming gear 95 to rotate. Through the synchronous rotation of the first forming gear 34 and the second forming gear 95, the metal foil is roll-formed to obtain metal honeycomb core fins, which are then led out through the guide channel 15. (See attached image for details.) Figure 11 As shown. The design of the adjusting gear structure can adjust and control the rotational clearance between the first forming gear 34 and the second forming gear 95, thus better ensuring the consistency of foil deformation.

[0047] For specific implementation, please refer to Figure 3As shown, the differential gear includes an adjusting differential gear 41 and a fixed differential gear 43. Both the adjusting differential gear 41 and the fixed differential gear 43 are fixed on the drive shaft 37. Both the adjusting differential gear 41 and the fixed differential gear 43 mesh with the driven adjusting gear 49. The fixed differential gear 43 is provided with an adjusting screw 42. More specifically, the inner hole of the fixed differential gear 43 mates with the gear base 45, and their positions are fixed by a gear positioning pin 44. The inner hole of the adjusting differential gear 41 mates with the gear base 45 and overlaps below the fixed differential gear 43. An adjusting positioning pin 46, from top to bottom, passes through the gear base 45 and the fixed differential gear 43 in sequence and is then installed in the positioning pin hole of the adjusting differential gear 41. Two threaded holes are machined from top to bottom on the gear base 45. These threaded holes communicate with adjusting screw holes on the fixed differential gear 43 and the driven adjusting gear 49, respectively, which are opened from left to right. The two adjusting screws engage with the threaded holes on the gear base 45 and are screwed into the gear base 45, tightening against the adjusting positioning pins 46 located in the adjusting screw holes. By changing the screw depth of the two adjusting screws 42 on the fixed differential gear 43 and the driven adjusting gear 49, the relative position of the gear base 45 and the adjusting differential gear 41 is changed. Since the gear base 45 and the fixed differential gear 43 are fixed in position by the gear positioning pins 44, it is equivalent to synchronously adjusting the relative positional relationship between the fixed differential gear 43 and the adjusting differential gear 41. After adjustment, the gear base 45 and the differential gear are locked with bolts, and the gear locking nut 47 is used to fix the gear base 45 to the drive shaft 37. The inner ring of the driven adjusting gear 49 mates with the gear base 45. The positions of the two are determined by the gear positioning pin 44, and they are fixedly connected by bolts. Finally, the gear is connected to the driven shaft 93 by bolts and gear locking washer 48.

[0048] In specific implementation, the drive shaft 37, the first forming gear 34, and other components can form a drive gear structure 3, see [reference needed]. Figure 4 As shown, the drive gear structure 3 includes a drive shaft locking nut 31, a drive shaft gear sleeve 32, a first forming gear 34 (i.e., the drive forming gear), an adjusting gear key 35, a drive shaft gear key 36, and a drive shaft 37.

[0049] For specific implementation, please refer to Figure 4As shown, limiting retaining rings 33 are provided on both sides of the first forming gear 34, and the diameter of the limiting retaining rings 33 is larger than the diameter of the first forming gear 34. The limiting retaining rings 33 are located outside the guide channel 15. The limiting retaining rings 33 can be connected to the first forming gear 34 by bolts, or they can be formed by preparing extended baffles on both sides of the first forming gear 34 during processing. The function of the limiting retaining rings 33 is to restrict the left and right movement of the metal foil during the metal honeycomb core fin forming process, ensuring that the metal foil passes smoothly and straight through the gap between the first forming gear 34 and the second forming gear 95. During operation, the first forming gear 34 restricts its relative rotation on the drive shaft 37 by the drive shaft gear key 36, and restricts its relative movement in the axial direction by the drive shaft gear sleeves 32 on both sides, the drive shaft shoulder (not shown in the figure), and the drive shaft locking nut 31, thereby achieving the purpose of connecting the first forming gear 34 and the drive shaft 37. The left side of the drive shaft 37 is connected to the adjusting gear structure 4 via the adjusting gear key 35, while the right side is connected to the power source 11 via the coupling 112.

[0050] In specific implementation, the driven shaft 93, the second forming gear 95, and other components can form a driven gear structure 9, see [reference needed]. Figure 5 As shown, the driven gear structure 9 is similar to the driving gear structure 3, except that the second forming gear 95 no longer has limiting retaining rings on both sides. The relative rotation of the second forming gear 95 on the driven shaft 93 is restricted by the driven shaft gear key 94, and the relative movement of the second forming gear 95 in the axial direction is restricted by the driven shaft gear sleeves 92 on both sides of the second forming gear 95, the shaft shoulder of the driven shaft 93 (not shown in the figure), and the driven shaft locking nut 91, thus achieving the purpose of connecting the second forming gear 95 and the driven shaft 93. The left side of the driven shaft 93 is connected to the driven adjusting gear 49 by a key.

[0051] In a specific implementation, the molded gear structure further includes two support structures disposed on the support frame 1. See [link to relevant documentation]. Figure 2 As shown, each of the support structures includes an angular contact ball bearing support structure 5 and a tapered roller bearing structure 10, with the angular contact ball bearing support structure 5 and the tapered roller bearing structure 10 of each support structure located at both ends of the drive shaft 37 or the driven shaft 93, respectively.

[0052] Furthermore, both the angular contact ball bearing support structure 5 and the tapered roller bearing structure 10 include a bearing, a bearing housing, and two dustproof rings. The bearing is disposed within the bearing housing, the dustproof rings are coaxial with the bearing, and the two dustproof rings are located on both sides of the bearing housing.

[0053] For details, see Figure 6As shown, the angular contact ball bearing support structure 5 includes angular contact ball bearing dust guards 51, a double-row angular contact ball bearing 52, and an angular contact ball bearing base 53. The inner ring of the double-row angular contact ball bearing 52 is installed inside the angular contact ball bearing base 53. Angular contact ball bearing dust guards 51 are provided on both sides and connected to the angular contact ball bearing base 53 by bolts. The inner ring of the double-row angular contact ball bearing 52 is fixed to the differential gear retaining ring (or the retaining ring of the driven adjusting gear 49) via the shoulder of the drive shaft 37 (or driven shaft 93). The purpose of using the double-row angular contact ball bearing 52 is to allow the drive shaft 37 and driven shaft 93 to better withstand radial loads, occupy less space, and provide a high-rigidity structure.

[0054] See Figure 7 As shown, the tapered roller bearing structure 10 includes tapered roller bearing clamping shims 101, two tapered roller bearings 102, tapered roller bearing retaining rings 103, and a tapered roller bearing base 104. The outer rings of the tapered roller bearings 102 are mounted inside the tapered roller bearing base 104 and fixed by the tapered roller bearing clamping shims 101 on both sides. The tapered roller bearing clamping shims 101 are connected to the tapered roller bearing base 104 by bolts. The inner rings of the tapered roller bearings 102 are fixed by the shoulder of the drive shaft 37 (or driven shaft 93) and the retaining ring of the differential gear (or the retaining ring of the driven adjusting gear 49). The two tapered roller bearings 102 are connected by the tapered roller bearing retaining rings 103. The main advantage of using tapered roller bearing 102 is its extremely high precision. Due to the tilt angle of its inner and outer rings, tapered roller bearing 102 can adapt to possible irregular movements in the device, reduce noise and wear caused by friction and vibration, and greatly ensure the consistency of metal foil forming.

[0055] In an improved embodiment, the molding apparatus further includes two molding gear gap adjustment structures for adjusting the gap between the first molding gear 34 and the second molding gear 95.

[0056] For specific implementation, please refer to Figure 1 and Figure 2 As shown, there are two forming gear gap adjustment structures. Each forming gear gap adjustment structure includes a first adjustment pad 6. The first adjustment pad 6 is disposed between the bearing seat of the drive shaft 37 and the bearing seat of the driven shaft 93 in the forming gear structure. Before operation, according to the size requirements of metal honeycomb core forming, the gap between the first forming gear 34 and the second forming gear 95 is adjusted by replacing the first adjustment pad 6 of different sizes.

[0057] For specific implementation, please refer to Figure 1 and Figure 2As shown, each of the molded gear clearance adjustment structures further includes a clamping structure 8, which is disposed on the support frame 1.

[0058] See Figure 8 As shown, the clamping structure 8 includes a clamping block 83, a clamping beam 84, a clamping screw 86, and a locking handle 87. The clamping beam 84 is fixed to the upper end of the support frame 1. The middle part of the clamping beam 84 is provided with a threaded hole through which the clamping screw 86 passes. The two are connected by a threaded fit and a locking nut to prevent loosening. The upper end of the clamping screw 86 is provided with the locking handle 87. The lower end of the clamping screw 86 is connected to the clamping block 83. The clamping block 83 is connected to the bearing housing (i.e., the angular contact ball bearing base 53 and the tapered roller bearing base 104) through the clamping screw locking nut 81 and the clamping screw locking washer 82.

[0059] Preferably, see Figure 8 As shown, a lifting beam 85 is also provided between the pressing beams 84 of the two forming gear gap adjustment structures, and the lifting beam 85 is fixed to the support frame 1 by bolts.

[0060] Preferably, see Figure 2 As shown, the clamping structure 8 also includes a second adjusting pad 2, which is disposed between the bearing seat of the driven shaft 93 and the support frame 1.

[0061] For specific implementation, please refer to Figure 9 As shown, the power source 11 includes a geared motor 113, which is mounted on a geared motor base 111. The output end of the geared motor 113 is connected to the drive shaft 37 via a coupling 112, and the input end of the geared motor 113 is connected to a servo motor 114. In this embodiment, the coupling 112 can be a rigid coupling, the geared motor 113 can be a planetary gear reducer, and the geared motor base 111 is fixed to the device base plate 20 of the support frame 1 by bolts.

[0062] For specific implementation, please refer to Figure 10As shown, the support frame 1 includes a device base plate 20, upright plates 14, and channel support plates 16. Two parallel upright plates 14 are fixed on the device base plate 20. The forming gear structure is located between the two upright plates 14, and each upright plate 14 is provided with a channel support plate 16 to support the guide channel 15. In this embodiment, the device base plate 20 is the base plate of the entire forming device, serving to support all structures. The two upright plates 14 are connected by a connecting base plate 19, two support columns 18, and two reinforcing connecting plates 17. Corresponding positioning pin holes are provided between the upright plates 14, the connecting base plate 19, and the reinforcing connecting plates 17. The position between them is determined by positioning pins 12, and then fixed by bolts. The upright plates 14 and the support columns 18 are connected by bolts. The guide channel 15 is connected to the channel support plate 16 by bolts. After the drive gear structure, driven gear structure and clamping structure 8 are installed, the guide channel 15 is fixed to the upright plate 14 by bolts after the position is determined by the positioning pin 12.

[0063] See Figure 10 As shown, the support frame 1 also includes a clamping pad 13. The clamping pad 13 is fixedly connected to the upright plate 14 by bolts after the drive gear structure and driven gear structure are installed, so as to fix the drive gear structure and driven gear structure in the axial direction.
