Description

Technical Field

[0001] The present invention relates to the technical field of honeycomb board processing, and particularly relates to a bending processing device for a stainless steel honeycomb core base material. Background Art

[0002] A honeycomb core material is a board made by firmly bonding two relatively thin panels to both sides of a relatively thick honeycomb-shaped core material, also known as a honeycomb sandwich structure. In addition, a honeycomb board also refers to a panel formed by welding a large number of cutoff waveguides together to form a cutoff waveguide array with a large opening area while preventing electromagnetic wave leakage. Its performance depends on materials, cell shapes and sizes, etc., and is anisotropic. When processing an aluminum alloy core material, in order to meet the requirements of the shape of the produced product, the aluminum alloy plate needs to be bent, and usually a bending device is required.

[0003] When a common bending device is in use, a V-shaped bending groove is opened on the workbench surface, and a hydraulic cylinder is used to lower the aluminum alloy plate to be extruded and bent in the bending groove. However, when the traditional extrusion block extrudes the plate into the bending groove, it will produce indentations on the upper surface of the plate, and at the same time, it will drive the bottom surface of the aluminum alloy plate to rub against the inner wall of the bending groove due to sliding, resulting in scratches and the bending angle cannot be adjusted, which cannot meet the working requirements of bending the honeycomb board core material. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a bending processing device for a stainless steel honeycomb core base material, which integrates pressing and bending of the honeycomb core base material by the downward pressing assembly, avoiding scratches on the surface of the base material, and aims to solve the problems in the background art.

[0005] To achieve the above technical purpose, the specific technical solution of the present invention is as follows. A bending processing device for a stainless steel honeycomb core base material proposed by the present invention includes: a machine base; a lifting mechanism installed above the machine base, and a downward pressing assembly is connected to the lifting mechanism for pressing and fixing the honeycomb core base material; a fixing plate fixedly connected to the machine base; a flipping plate for bending the honeycomb core base material, a pair of support frames are connected to the machine base, the flipping plate is rotatably connected between the two support frames, and when the downward pressing assembly continues to descend after pressing and fixing the honeycomb core base material, it can drive the flipping plate to flip; a pair of slide rails are symmetrically arranged on the machine base, a slide seat is slidably connected to the slide rails, and a guiding column is fixedly connected to the machine base, a lifting sleeve is slidably connected to the guiding column, when the downward pressing assembly descends, it can drive the lifting sleeve to descend, and a return spring is connected to the surface of the guiding column; a first connecting rod is rotatably connected between the lifting sleeve and the slide seat, and a second connecting rod is rotatably connected between the slide seat and the flipping plate.

[0006] As a preferred technical solution of the present invention, the pressing-down assembly includes a connecting plate and a pressing plate. The connecting plate is fixedly connected to the lifting mechanism, and an elastic component is connected between the pressing plate and the connecting plate. A pressing frame is fixedly connected to the connecting plate, and a pressing sleeve is fixedly connected to the pressing frame for driving the lifting sleeve to descend.

[0007] As a preferred technical solution of the present invention, one end of the pressing plate is connected with a top rod.

A guiding rod fixedly connected to the top rod and movably connected to the pressing plate is provided on the top rod, and a fine-tuning bolt is rotatably connected to the top rod. The fine-tuning bolt is threadedly connected to the pressing plate.

[0008] As a preferred technical solution of the present invention, a sliding groove is provided on the sliding seat. A first slider and a second slider are slidably connected in the sliding groove. One end of a first connecting rod is hinged to the first slider; one end of a second connecting rod is hinged to the second slider, and a connecting column rotatably connected to the second connecting rod is fixedly connected to the turning plate.

[0009] As a preferred technical solution of the present invention, a bidirectional screw rod is rotatably connected in the sliding groove. Thread lines with opposite directions are provided on the surfaces at both ends of the bidirectional screw rod, and the two ends of the bidirectional screw rod are respectively threadedly connected to the first slider and the second slider.

[0010] As a preferred technical solution of the present invention, a groove is provided on the turning plate. A top plate is connected in the groove. The top plate is attached to the surface of the honeycomb core substrate, and a pair of connecting blocks are symmetrically connected to the inner wall of the groove. The top plate is rotatably connected to the connecting blocks.

[0011] As a preferred technical solution of the present invention, a connecting groove is provided on the inner wall of the groove. The connecting block is slidably connected to the connecting groove, a first elastic member is fixedly connected between the connecting block and the connecting groove, and a second elastic member is fixedly connected between the top plate and the bottom of the groove.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Embodiment: This embodiment discloses a bending processing device for a stainless steel honeycomb core substrate, as Figures 1-7As shown in the figure, it includes: a machine base 1; a lifting mechanism 5, which uses a hydraulic cylinder. The lifting mechanism 5 is installed above the machine base 1, and a pressing component 4 is connected to the lifting mechanism 5 for tightly fixing the honeycomb core substrate; a fixing plate 2, fixedly connected to the machine base 1, and a placing groove with the same width as the honeycomb core substrate is provided on the fixing plate 2; a flipping plate 3 for bending the honeycomb core substrate. A pair of support frames 15 are connected to the machine base 1, and the positions of the support frames 15 on the machine base 1 can be adjusted. The flipping plate 3 is rotatably connected between the two support frames 15. When the pressing component 4 continues to descend after tightly fixing the honeycomb core substrate, it can drive the flipping plate 3 to automatically flip, thereby driving the honeycomb core substrate to bend.

[0025] Preferably, a fixing seat 13 is fixedly connected to the machine base 1 through bolts. The fixing seat 13 is provided with a pair that corresponds to the support frames 15 one by one. A screw rod 14 is rotatably connected to the fixing seat 13. The screw rod 14 is threadedly connected to the support frame 15, and a sliding rod 16 that is slidably connected to the fixing seat 13 is fixedly connected to the support frame 15. By rotating the screw rod 14, the support frame 15 can be driven to move, thereby driving the flipping plate 3 to move away from or close to the fixing plate 2, and then making a fine adjustment to the distance between the flipping plate 3 and the fixing plate 2.

[0026] As Figures 3-4As shown in the figure, a pair of slide rails 12 are symmetrically arranged on the machine base 1. A slide seat 6 is slidably connected to the slide rails 12. And a vertically arranged guide post 9 is fixedly connected to the machine base 1. There are a pair of guide posts 9. A lifting sleeve 10 is slidably connected to the guide posts 9. When the pressing component 4 descends, it can drive the lifting sleeve 10 to descend. And a return spring 11 is connected to the surface of the guide post 9 for resetting the lifting sleeve 10. A first connecting rod 8 is rotatably connected between the lifting sleeve 10 and the slide seat 6. And a second connecting rod 7 is rotatably connected between the slide seat 6 and the turning plate 3. Among them, a chute 61 is provided on the slide seat 6. A first slider 62 and a second slider 63 are slidably connected in the chute 61. One end of the first connecting rod 8 is hinged to the first slider 62. One end of the second connecting rod 7 is hinged to the second slider 63. And a connecting column 33 rotatably connected to the second connecting rod 7 is fixedly connected to the turning plate 3. A bidirectional screw 64 is rotatably connected in the chute 61. A pair of thread lines with opposite directions are provided on the surfaces of both ends of the bidirectional screw 64. And both ends of the bidirectional screw 64 are respectively threadedly connected to the first slider 62 and the second slider 63. By rotating the bidirectional screw 64, the first slider 62 and the second slider 63 can be driven to approach or move away from each other, so as to adjust the distance between the first slider 62 and the second slider 63, and further adjust the turning angle of the turning plate 3. When the lifting sleeve 10 descends, it drives the slide seat 6 to slide, and the slide seat 6 drives the turning plate 3 to turn, so as to bend the base material. If a larger horizontal turning angle of the turning plate 3 is required, before the pressing action, the bidirectional screw 64 can be manually rotated to drive the first slider 62 and the second slider 63 to approach each other, so that the distance between the first slider 62 and the second slider 63 becomes smaller. Then when the pressing component 4 drives the lifting sleeve 10 to descend to the lowest position, at this time the horizontal turning angle of the turning plate 3 will be larger. Similarly, when the distance between the first slider 62 and the second slider 63 is adjusted to be larger, when the pressing component 4 drives the lifting sleeve 10 to descend to the lowest position, at this time the horizontal turning angle of the turning plate 3 will be smaller. It should be noted that in this embodiment, only the turning angle of the turning plate 3 can be finely adjusted, and it is not applicable to large-angle adjustment. When the distance between the first slider 62 and the second slider 63 is adjusted from small to large, the difference between the maximum turning angle and the minimum turning angle of the turning plate 3 is about 5°.

[0027] As Figures 5-6As shown in the figure, a groove 31 is provided on the flipping plate 3. A top plate 32 is connected inside the groove 31. When the flipping plate 3 is horizontal, the top plate 32 is flush with the fixing plate 2 in height. When the honeycomb core substrate is horizontally placed on the fixing plate 2, the top plate 32 fits against the lower surface of the honeycomb core substrate. The top plate 32 fits against the surface of the honeycomb core substrate. A pair of connecting blocks 35 are symmetrically connected to the inner wall of the groove 31. The top plate 32 is rotatably connected to the connecting blocks 35. A connecting groove 37 is provided on the inner wall of the groove 31. The connecting blocks 35 are slidably connected to the connecting groove 37. A first elastic member 36 is fixedly connected between the connecting blocks 35 and the connecting groove 37. A second elastic member 34 is fixedly connected between the top plate 32 and the bottom of the groove 31. Since the flipping of the flipping plate 3 will drive the bending of the honeycomb core substrate, and there is a difference in the position of the rotation point between the honeycomb core substrate and the flipping plate 3, relative sliding occurs between the flipping plate 3 and the honeycomb core substrate. By setting that the top plate 32 can rotate and move in the groove 31, the top plate 32 can always fit against the entire surface of the honeycomb core substrate, avoiding indentations on the honeycomb core substrate caused by the top plate 32. And the top plate 32 can slide in the groove 31, avoiding scratches on the surface of the honeycomb core substrate caused by the sliding between the top plate 32 and the honeycomb core substrate.

[0028] As Figure 7 shown, the pressing-down assembly 4 includes a connecting plate 41 and a pressing plate 42. The connecting plate 41 is fixedly connected to the lifting mechanism 5. An elastic assembly 48 is connected between the pressing plate 42 and the connecting plate 41. The elastic assembly includes a sliding rod and a spring. The spring is sleeved on the sliding rod. A pressing frame 46 is fixedly connected to the connecting plate 41. A pressing sleeve 47 is fixedly connected to the pressing frame 46. The pressing sleeve 47 can be sleeved on the guiding column 9. The pressing sleeve 47 is used to drive the lifting sleeve 10 to descend. One end of the pressing plate 42 is connected with a top rod 43. The honeycomb core substrate is bent with the top rod 43 as the rotation point. A guiding rod 44 which is movably connected to the pressing plate 42 is fixedly connected to the top rod 43. A fine-tuning bolt 45 is rotatably connected to the top rod 43. The fine-tuning bolt 45 is threadedly connected to the pressing plate 42. The position of the top rod 43 can be adjusted by the fine-tuning bolt 45 to adjust the bending point of the honeycomb core substrate.

[0029] Working principle: Place the honeycomb core substrate at the correct position on the fixing plate 2. The lifting mechanism 5 drives the pressing-down assembly 4 to descend. During the descending process, the pressing plate 42 first contacts the surface of the honeycomb core substrate, pressing and fixing the honeycomb core substrate on the fixing plate 2. When the pressing-down assembly 4 continues to descend, the distance between the connecting plate 41 and the pressing plate 42 becomes smaller. The pressing sleeve 47 drives the lifting sleeve 10 to descend. The descending of the lifting sleeve 10 drives the sliding seat 6 to slide. When the sliding seat 6 slides, it drives the flipping plate 3 to rotate upward, thereby bending the honeycomb core substrate. During the bending process, the top plate 32 always contacts the entire surface of the honeycomb core substrate and the relative position remains unchanged, avoiding scratches on the surface of the honeycomb core substrate.

[0030] Finally, it should be noted that in the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "vertical", "upper", "lower", "horizontal", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.
