Description

Technical Field

[0001] This utility model belongs to the technical field of tension bending and straightening machines, and relates to an aluminum powder suction device for tension bending and straightening machines. Background Technology

[0002] In metal processing and transportation, metal sheets are generally transported in coils. To meet subsequent processing requirements, factories use various straightening methods, with multi-roll straighteners being a widely used option. When thin sheets pass through this type of straightener, they do not stretch; instead, large waves are reduced to smaller ones, resulting in a nearly flat surface. However, this method is difficult to use for sheets less than 0.8mm thick. Tension-bending straighteners, on the other hand, can induce both longitudinal and transverse deformation in thin sheets simultaneously, significantly improving their flatness and material properties, thus greatly advancing thin sheet straightening technology.

[0003] During the bending and straightening process of aluminum plates, fine aluminum powder particles are generated on the surface of the aluminum plates. If the aluminum powder particles continue to remain on the aluminum plates, they will affect the subsequent surface flatness of the aluminum plates. Excess aluminum powder needs to be removed. Therefore, a bending and straightening machine aluminum powder suction device is needed to solve the above problem. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The following is in conjunction with the appendix Figures 1 to 3 The specific embodiments of this utility model will be described in further detail.

[0022] Depend on Figures 1 to 3 As shown, this utility model includes a protective cover 1 detachably connected to a bending and straightening machine. In order to remove the aluminum powder generated by the bending and straightening machine, a four-way pipe 2 is detachably connected to the upper side of the protective cover 1. An extension pipe 3 is detachably connected to the front and rear sides of the lower part of the four-way pipe 2. A connecting cover 4 is detachably connected to the end of each extension pipe 3 away from the four-way pipe 2. Multiple protective air ducts 5 are provided inside the protective cover 1. The protective air ducts 5 are detachably connected to the protective cover 1. During the negative pressure absorption of aluminum powder, some aluminum powder will adhere to the surface of the protective air ducts 5. The protective air ducts can be replaced regularly for cleaning. The upper side of each protective air duct 5 passes through the upper side of the protective cover 1 and connects to the bottom of the four-way pipe 2.

[0023] It should be noted that the bending straightening machine is existing technology. In this embodiment, it specifically refers to an aluminum plate bending straightening machine, such as the bending straightening machine disclosed in Chinese invention patent with publication number CN109604378B, which is used to straighten the bending of aluminum plates. It has openings on both sides for maintenance of the straightening rollers. It is existing technology and will not be described in detail here. The bottom shape of the protective cover 1 is adapted to the upper shape of the bending straightening machine, and it can continuously apply negative pressure to the upper part of the bending straightening machine.

[0024] It should be noted that the upper side of the four-way pipe 2 is also connected to a negative pressure fan system, which is used to provide negative pressure to the inside of the four-way pipe 2, such as a cyclone separator or a negative pressure fan of model YFIAD, and is equipped with a dust collection system for removing aluminum powder. It will not be described in detail here. During the bending and straightening process of the aluminum plate, fine aluminum powder particles will be generated on the surface of the aluminum plate. Under the negative pressure inside the protective cover 1, the aluminum powder particles will rise through the protective air duct 5 into the four-way pipe 2 and finally be discharged, reducing the probability of aluminum powder particles falling back onto the surface of the aluminum plate.

[0025] In use, the protective cover 1 can be directly placed on the upper side of the bending and straightening machine, and the protective cover 1 can be placed on the inspection openings on the front and rear sides of the bending and straightening machine through the extension pipe 3. Since the extension pipe 3 is directly connected to the four-way pipe 2, it can directly absorb the aluminum powder scattered at the inspection opening, and achieve a better aluminum powder absorption effect. By setting the connecting cover 4 which is detachably connected to the extension pipe 3, it is convenient for the staff to remove the connecting cover 4 when inspecting the straightening roller, making it convenient for the staff to operate and use.

[0026] Furthermore, by Figures 1 to 3 As shown, in order to facilitate the connection between the protective cover 1 and the bending straightening machine, multiple connecting plates 6 are fixedly connected to the outer side of the protective cover 1, and each connecting plate 6 has a first mounting hole 7 symmetrically opened on its upper and lower sides.

[0027] In use, the connecting plate 6 can be connected to the outer shell of the bending and straightening machine through the mounting holes using bolts, and the connecting plate 6 can be connected to the protective cover 1, so that the protective cover 1 can be fixed and supported as a whole through the connecting plate 6.

[0028] Furthermore, by Figures 1 to 3 As shown, in order to facilitate the adaptation of the position of the inspection port, multiple first connecting pipes 8 are connected to the front and rear sides of the four-way pipe 2. Each extension pipe 3 is detachably connected to the corresponding first connecting pipe 8. A connecting mechanism 9 is provided between the four-way pipe 2 and the protective cover 1, as well as between each first connecting pipe 8 and the corresponding extension pipe 3.

[0029] In use, by setting the connecting mechanism 9, the angle between each extension pipe 3 and the first connecting pipe 8 can be adjusted. At this time, it is only necessary to adjust the length of the extension pipe 3 during the extension process, so that the lower part of the extension pipe 3 can be adapted to the maintenance port at different positions, which is convenient for use with different models of bending and straightening machines.

[0030] Furthermore, by Figures 1 to 3 As shown, in order to facilitate the installation of the device by the staff, the connecting mechanism 9 includes a first fixing ring 10 and a second fixing ring 11, and fixing holes are provided on both the first fixing ring 10 and the second fixing ring 11.

[0031] In use, bolts and nuts can be passed through the corresponding fixing holes to make the first fixing ring 10 and the second fixing ring 11 fit tightly together, thus completing the connection between the two pipes.

[0032] It should be noted that the outer side of the lower part of the four-way pipe 2 and the outer side of each first connecting pipe 8 are fixedly connected to the corresponding first fixing ring 10, and the upper side of the protective cover 1 and the outer side of the extension pipe 3 are fixedly connected to the corresponding second fixing ring 11.

[0033] Furthermore, by Figures 1 to 3 As shown, in order to make way for the pipeline of the bending straightening machine, pipe passage holes 12 are provided on the front and rear sides of the protective cover 1, and a rubber ring 13 is provided inside each pipe passage hole 12.

[0034] When in use, the cables and pipes that need to be connected to the bending straightening machine can be passed through the pipe through hole 12. The rubber ring 13 can reduce the gap between the pipe through hole 12 and the pipe, thereby maintaining the negative pressure inside the protective cover 1.

[0035] Furthermore, by Figures 1 to 3 As shown, in order to achieve a better aluminum powder adsorption effect, the connecting cover 4 includes a first sleeve 14 and a square sleeve 15. The first sleeve 14 is provided with an adjustment mechanism 16 on the side near the extension pipe 3. The first sleeve 14 is detachably connected to the extension pipe 3 through the adjustment mechanism 16. A square ring 17 is fixedly connected to the end of the square sleeve 15 away from the first sleeve 14. The square ring 17 is made of rubber and has a large width. When the device is installed, the square ring 17 can be trimmed according to the actual situation of the inspection port so that it corresponds to the outline of the inspection port. When the square ring 17 is installed, it can be pasted on the outside of the inspection port with self-adhesive, thereby ensuring the negative pressure stability of the inspection port position. The square sleeve 15 is made of plastic material, which is lightweight and convenient for maintenance and replacement.

[0036] When in use, the square ring 17 can be set to fit the shape of the inspection port, making the device easy to use.

[0037] Furthermore, by Figures 1 to 3 As shown, in order to adjust the angle of the square sleeve 15 to easily adapt to the shape and position of the inspection port, the adjustment mechanism 16 includes a first adjustment ring 18 and a second adjustment ring 19. The first adjustment ring 18 is fixedly connected to the first sleeve 14, and the second adjustment ring 19 is fixedly connected to the extension pipe 3. A fixed fork 20 is fixedly connected to the side of the first adjustment ring 18 close to the second adjustment ring 19, and a fixed frame 21 is fixedly connected to the side of the second adjustment ring 19 away from the first adjustment ring 18. The fixed frame 21 and the fixed fork 20 cooperate with each other to form a detachable and directionally adjustable structure for the connecting cover 4.

[0038] It should be noted that the outer side of the fixing bracket 21 is a regular dodecagon. During device installation, the angle of the first adjusting ring 18 relative to the second adjusting ring 19 can be adjusted by directly engaging the fixing fork 20 with the side of the fixing bracket 21 at a suitable angle. This allows the angle of the square sleeve 15 relative to the extension pipe 3 to be adjusted, facilitating installation and debugging by the staff.

[0039] When using this utility model, the protective cover 1 can be directly placed on the upper side of the bending and straightening machine, and the protective cover 1 can be placed on the inspection openings on the front and rear sides of the bending and straightening machine through the extension pipe 3. Since the extension pipe 3 is directly connected to the four-way pipe 2, it can directly absorb the aluminum powder scattered at the inspection opening, and achieve a better aluminum powder absorption effect. By setting the connecting cover 4 which is detachably connected to the extension pipe 3, it is convenient for the staff to remove the connecting cover 4 when inspecting the straightening roller, making it convenient for the staff to operate and use.

[0040] This utility model has a novel structure, ingenious design, and simple and convenient operation. Through this design, it effectively achieves the purpose of removing aluminum powder generated by the bending and straightening machine, facilitates the connection of the protective cover 1 to the bending and straightening machine, facilitates the adaptation of the inspection port position, facilitates the installation of the device by the staff, and facilitates the relocation of the pipeline of the bending and straightening machine, thus achieving a better aluminum powder adsorption effect.
