Detailed Implementation

[0037] The technical solutions of this application will be further described below with reference to specific embodiments, but this application is not limited to these embodiments.

[0038] like Figures 1 to 9 As shown in the figure, this embodiment proposes a spiral bending module, specifically as follows: Figures 1 to 3 ,as well as Figures 7 to 9 As shown, it includes a bending mechanism 11 for bending a horizontal strip 46 into a spiral shape. The bending mechanism 11 includes:

[0039] A first support base 10 has a first horizontal plate 12 and a first vertical plate 13, with the first vertical plate 13 fixed on the first horizontal plate 12.

[0040] The first drive assembly 14 is mounted on the first vertical plate 13 and has a first rotating shaft 15. A first sleeve 16 is fixed on the first rotating shaft 15 and a first bayonet 17 is provided on the first sleeve 16. The first bayonet 17 is used to limit the end of the material strip 46.

[0041] A feeding platform 18 is located on one side of the first sleeve 16. The feeding platform 18 is provided with a slide rail 19, which is used to guide the movement direction of the material belt 46.

[0042] An elastic extrusion assembly is used to elastically extrude the surface of the strip 46.

[0043] The technical advantage of this solution is that it can bend 46 rolls of material strip into a spiral shape, which has the advantages of compact structure and convenient processing.

[0044] The bending process of strip 46 is as follows:

[0045] The material strip 46 is pushed into the first slot 17 of the first rotating shaft 15 through the feeding platform 18. The first drive component 14 works. At this time, the material strip 46 is bent when the first rotating shaft 15 rotates. Since the elastic extrusion component is used in this solution, the elastic extrusion component will undergo elastic displacement during the bending process of the material strip 46, so that the material strip 46 can be processed into a planar spiral shape.

[0046] The first drive assembly 14 in this scheme consists of a reducer and a motor. The reducer is installed on the output end of the motor, and the output shaft of the reducer is fixed to the first rotating shaft 15 by a coupling.

[0047] Furthermore, the strip 46 is made of materials such as aluminum alloy, and stress is released through plastic deformation, thereby making the stress distribution relatively uniform, and the elastic extrusion component can dynamically compensate for the stress.

[0048] Furthermore, this solution controls the screw pitch by controlling the feeding speed and the rotational speed of the first drive component 14.

[0049] In one embodiment of this invention, the elastic extrusion assembly includes an extrusion mechanism 20, which includes a support 21, a guide rod 22, an elastic element 23, a roller seat 24, and a roller 25. The support 21 is fixed on the first horizontal plate 12, and the roller seat 24 is mounted on the support 21 via the guide rod 22. The elastic element 23 is sleeved on the guide rod 22. The roller 25 is rotatably mounted on the roller seat 24 and is used to elastically extrude the surface of the material strip 46.

[0050] Furthermore, there are multiple guide rods 22, and some guide rods 22 are fitted with elastic elements 23 on their outer periphery. One end of the elastic element 23 is fixed on the support 21, and the other end of the elastic element 23 is fixed on the roller seat 24.

[0051] This solution uses an elastic element 23 fitted onto the guide rod 22 to achieve dynamic pressure compensation of the roller 25 on the material strip 46. The elastic element 23 is a spring.

[0052] Furthermore, in this design, the strip 46 has a width of 50mm and a thickness of 0.5-1.5mm. The maximum permissible working stroke of the spring is 25-19mm, and the maximum load is 1421N.

[0053] In one embodiment of this invention, there are two extrusion mechanisms 20. One extrusion mechanism has a roller 25 that extrudes the strip 46 in a horizontal direction, while the other extrusion mechanism has a roller 25 that extrudes the strip 46 in a vertically upward direction.

[0054] The technical effect of this solution is that the synchronous action of the horizontal and vertical extrusion rollers can eliminate the difference in transverse and longitudinal stress of the material strip 46, thereby improving the uniformity of material deformation by more than 40%.

[0055] In one embodiment of this invention, a rubber layer 26 is fixed to the circumferential surface of the roller 25. This layer increases the friction on the material strip 46 and protects the material strip 46 from scratches. The rubber layer 26 can absorb high-frequency vibrations, thereby improving the bending effect of the material strip 46.

[0056] As one embodiment of this example, the bending mechanism 11 further includes a guard plate 27 and a first translation mechanism 28. The guard plate 27 is located at the end of the first rotating shaft 15 away from the first driving component 14, and the guard plate 27 is provided with a through hole for passing through the first rotating shaft 15.

[0057] The guard plate 27 is mounted on the first horizontal plate 12 via a first translation mechanism 28, and the first translation mechanism 28 is used to drive the guard plate 27 to move along the axial direction of the first rotation axis 15.

[0058] In this design, the guard plate 27 is used to support the first rotating shaft 15, thereby facilitating the force balance at both ends of the first rotating shaft 15.

[0059] Furthermore, the first translation mechanism 28 can be a slide cylinder or a linear motor, as is available in the prior art.

[0060] Furthermore, a limiting block is provided at one end of the first rotating shaft 15 near the first drive assembly 14. The limiting block and the guard plate 27 work together to prevent the material strip 46 from moving along the axial direction of the first rotating shaft 15 during the bending process.

[0061] After the material strip 46 is finished being bent, the first translation mechanism 28 moves the guard plate 27 away from the first rotating shaft 15, which makes it easier to remove the planar spiral material strip 46.

[0062] At this point, the outermost edge of the processed strip 46 has a curled edge and is not curved. Therefore, this solution adds a second process and further adds a bending mechanism 29 to bend the curled edge of the spiral strip 46.

[0063] As one implementation method of this embodiment, such as Figures 4 to 6 As shown, the bending mechanism 29 includes:

[0064] The second support base 30 has a second horizontal plate 31 and a second vertical plate 32, and the second vertical plate 32 is fixed on the second horizontal plate 31.

[0065] The second drive assembly 33 is mounted on the second vertical plate 32 and has a second rotating shaft 34. A second sleeve 35 is fixed on the second rotating shaft 34. A second bayonet 36 is provided on the second sleeve 35. The second bayonet 36 is used to limit the inner end of the material strip 46 in the spiral state.

[0066] A pressing assembly for pressing the surface of the spiral strip 46.

[0067] In this scheme, the second drive component 33 is used to drive the material belt 46 to rotate, and the material belt 46 is subjected to secondary extrusion by the pressing component, which in turn bends the outermost end of the spiral material belt 46.

[0068] The second drive assembly 33 in this solution consists of a reducer and a motor. The reducer is installed on the output end of the motor, and the output shaft of the reducer is fixed to the second rotating shaft 34 by a coupling.

[0069] Furthermore, the pressing assembly includes a first extruder 37 and a second extruder 38, wherein the first extruder 37 is used to press downward on the surface of the spiral strip 46, and the second extruder 38 is used to press upward on the surface of the spiral strip 46.

[0070] As one embodiment of this invention, the first extrusion member 37 includes a first telescopic member 39 and a first pressure block 40. The first telescopic member 39 is mounted on the second vertical plate 32. The first telescopic member 39 has a vertically downward output end, and the first pressure block 40 is fixed on the output end of the first telescopic member 39.

[0071] The second extrusion member 38 includes a second telescopic member 41 and a second pressure block 42. The second telescopic member 41 is mounted on the second horizontal plate 31 and has a vertically upward output end. The second pressure block 42 is fixed on the output end of the second telescopic member 41.

[0072] In this scheme, the synchronous operation of the first extruder 37 and the second extruder 38 forms symmetrical pressure at the upper and lower ends of the spiral strip 46.

[0073] Furthermore, the first pressing block 40 and the second pressing block 42 are respectively provided with arc-shaped openings 45. The diameter of the circle where the arc-shaped opening 45 is located is smaller than the diameter of the circle where the outermost ring of the spiral strip 46 is located. This is used to make the two ends of the arc-shaped opening 45 in line contact with the surface of the spiral strip 46 along its own curvature direction. This solution adopts two line contact bending schemes, which can effectively bend the outermost end of the spiral strip 46 and solve the technical problem of the existing spiral strip 46 corners curling up.

[0074] In this design, the first telescopic component 39 and the second telescopic component 41 are respectively pneumatic cylinders or hydraulic cylinders.

[0075] Furthermore, this solution also includes a baffle 43 and a second translation mechanism 44. The baffle 43 has a mounting hole for rotatably mounting a second rotating shaft 34. The second translation mechanism 44 is used to drive the baffle 43 to move so that the baffle 43 and the second rotating shaft 34 can be separated or joined, which facilitates the loading and unloading of the spiral material belt 46.

[0076] Furthermore, the second translation mechanism 44 can be a slide cylinder or a linear motor as used in the prior art.

[0077] In addition, this embodiment also proposes a bending device, including the spiral bending module described above.

[0078] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
