Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical processing, and in particular relates to a dieless progressive forming device and a forming method for an aluminum alloy. Background Art

[0002] When it comes to forming complex, personalized, thin-walled metal components in small batches, the traditional stamping process suffers from high costs, low efficiency, and poor flexibility. To overcome these issues, the use of sheet metal incremental forming (IMF) instead of stamping to form these components achieves high-precision, high-efficiency, and low-cost forming.

[0003] However, for thin-walled metal structural parts with sidewall features, conventional progressive forming devices cannot smoothly form the sidewall features of the parts, resulting in the parts not being able to be formed in one go, which in turn leads to low forming efficiency and forming precision of the parts, resulting in low flexibility of the entire forming process. Chinese patent document with publication number CN117340110A discloses a dieless progressive forming method and device using a planar support. The patent fixes the sheet metal on a lifting platform through a blank holder, and the sheet metal can be raised and lowered along with the lifting platform; a tool head is provided above the sheet metal, and the tool head rolls the sheet metal along a specific trajectory in the XY plane to obtain the part shape, and the movement value of the tool head in the Z-axis direction is assigned to the lifting platform motion control unit as the Z-axis movement value of the lifting platform. However, the above-mentioned dieless progressive forming device cannot accurately rotate the workpiece to any angle for sidewall processing, and thus cannot achieve the integrated forming of radially concave and circumferentially concave sidewalls of thin-walled structural parts.

[0004] Therefore, it is necessary to propose an aluminum alloy dieless progressive forming device and forming method to solve the above technical problems existing in the prior art. Summary of the Invention

[0057] Example 1

[0058] like Figures 1 to 9 As shown, this embodiment describes an aluminum alloy dieless incremental forming device, which includes a base, a support plate 16 , a rotating frame, a rotating support plate 13 , a lifting assembly, a first drive assembly, a second drive assembly, a fixing member, and a tool head 26 .

[0059] A rotating frame is provided on each of the two opposite sides of the support plate 16, and each rotating frame is hinged to one side of the base. The output end of the first drive assembly is connected to one of the rotating frames, and the first drive assembly is used to drive the rotating frame to rotate. The rotating support disk 13 is provided on the support plate 16, and the output end of the second drive assembly passes through the support plate 16 and is connected to the rotating support disk 13, and the output end of the second drive assembly is rotatably connected to the support plate 16, and the second drive assembly is used to drive the rotating support disk 13 to rotate. The lifting assembly is provided on the rotating support disk 13, and a fixing part is provided on the lifting assembly, and the fixing part is used to fix the aluminum alloy workpiece 14. The fixing part drives the aluminum alloy workpiece 14 to rotate, swing or move up and down, and cooperates with the tool head 26 to perform dieless progressive forming on the aluminum alloy workpiece 14.

[0060] The base of the device includes a base plate 4, a first support member 1, and a second support member 5. The first support member 1 is bolted to the left side of the base plate 4, and the second support member 5 is bolted to the right side of the base plate 4. A rotating frame, namely the left rotating frame 17, is hingedly connected to the first support member 1; a rotating frame, namely the right rotating frame 19, is hingedly connected to the second support member 5. The left side of the support plate 16 is bolted to the left rotating frame 17, and the right side of the support plate 16 is bolted to the right rotating frame 19.

[0061] The first drive assembly of this device includes a first motor 6, a first reducer 7, and a rotating shaft 9. The output shaft of the first motor 6 is connected to the input shaft of the first reducer 7, which in turn is connected to the rotating shaft 9. The rotating shaft 9 passes through the second support member 5 and is connected to the right rotating frame 19. A third bearing 23 is mounted on the second support member 5, through which the rotating shaft 9 is rotatably connected to the second support member 5. The outer ring of the third bearing 23 is bolted to the right rotating frame 19, while the inner ring of the third bearing 23 is connected to the rotating shaft 9, allowing the rotating shaft 9 to rotate relative to the right rotating frame 19. The first motor 6 and the first reducer 7 are fastened together by screws. When the output shaft of the first motor 6 rotates, the first reducer 7 and the rotating shaft 9 drive the right rotating frame 19 to swing relative to the first and second support members 1 and 5, thereby driving the support plate 16 and the aluminum alloy workpiece 14 mounted thereon to swing. The first drive assembly also includes a bracket 18. The bracket 18 is bolted to the outside of the support member through which the rotating shaft 9 passes, i.e., the outside of the second support member 5. The first reducer 7 is fixed to the bracket 18.

[0062] A third bearing 23 is also mounted on the first support member 1 of the device, and the left rotating frame 17 is rotatably connected to the first support member 1 via the third bearing 23. A bearing end cap 8 is also provided on the first support member 1 to fix the third bearing 23 on the first support member 1.

[0063] When the first motor 6 drives the first reducer 7, the first reducer 7 rotates the rotating shaft 9, which in turn causes the right rotating frame 19 and the left rotating frame 17 to swing. The swing angles of the right rotating frame 19 and the left rotating frame 17 can be set by the numerical control unit. As the right rotating frame 19 and the left rotating frame 17 swing, they cause the support plate 16 and the aluminum alloy workpiece 14 on the support plate 16 to swing at the same angle.

[0064] The second drive assembly of the device includes a second motor 2, a second reducer 3, and a bearing shaft 24. The second reducer 3 is arranged below the support plate 16. The output shaft of the second motor 2 is connected to the input shaft of the second reducer 3. The output shaft of the second reducer 3 is connected to the bearing shaft 24. The bearing shaft 24 passes through the support plate 16 and is connected to the rotating support plate 13. The bearing shaft 24 is rotatably connected to the support plate 16. The second drive assembly also includes a first bearing 22 and a second bearing 25. The first bearing 22 and the second bearing 25 are both connected to the support plate 16, and the first bearing 22 and the second bearing 25 are both sleeved on the bearing shaft 24. The bearing shaft 24 is rotatably connected to the support plate 16 via the first bearing 22 and the second bearing 25. The rotating support plate 13 and the support plate 16 are connected via the bearing shaft 24. The bearing shaft 24 and the support plate 16 are connected via the first bearing 22. The second reducer 3 and the bearing shaft 24 are fixed via the second bearing 25 and the thrust bearing end cover 12.

[0065] When the second motor 2 drives the second reducer 3 to move, the second reducer 3 drives the rotary support plate 13 to rotate through the bearing shaft 24 . The rotary support plate 13 rotates while driving the aluminum alloy workpiece 14 to rotate by the same angle.

[0066] The lifting assembly of this device includes a cylinder 10 and a guide rod 15. The cylinder 10 is fixed to a rotating support plate 13, with a fixed member fixed to the piston rod of the cylinder 10. The bottom end of the guide rod 15 is fixed to the rotating support plate 13, and the top end of the guide rod 15 passes through the fixed member, with the guide rod 15 and the fixed member slidingly engaged. The piston rod of the cylinder 10 can drive the fixed member to move up and down. The cylinder 10 and the rotating support plate 13 are fixed by a positioning sleeve and locked with bolts.

[0067] The device's fixed components include a support plate 20, a forming plate 21, and a pressure plate 11. The support plate 20 is fixed to the piston rod of the oil cylinder 10. The top end of the guide rod 15 passes through the support plate 20, and the guide rod 15 and the support plate 20 are slidably engaged. The forming plate 21 is fixed to the support plate 20, and the pressure plate 11 is removably mounted on the forming plate 21. The aluminum alloy workpiece 14 is fixed between the pressure plate 11 and the forming plate 21 and locked with bolts. The pressure plate 11, forming plate 21, and support plate 20 are all fixed by bolts, and the piston rod of the oil cylinder 10 is also fixed to the support plate 20 by bolts.

[0068] The forming plate 21 of this embodiment has a circular center shape to accommodate the circular-opening aluminum alloy workpiece 14 and promote uniform material flow. The forming plate 21 is also removable from the support plate 20 for easy replacement. For example, if the aluminum alloy workpiece 14 has a square opening, replacing it with a forming plate 21 with a square center shape promotes uniform material flow.

[0069] The oil cylinder 10 is externally connected to an oil supply unit to realize the lifting of the support plate 20. The lifting of the support plate 20 drives the aluminum alloy workpiece 14 to lift and lower simultaneously.

[0070] The device also includes a numerical control unit, which is connected to the control terminal of the lifting assembly (the control terminal of the oil cylinder 10), the control terminal of the first drive assembly (the control terminal of the first motor 6), the control terminal of the second drive assembly (the control terminal of the second motor 2), and the control terminal of the tool head 26. The operator controls the movement of the oil cylinder 10, the first motor 6, the second motor 2, and the tool head 26 through the numerical control unit, and coordinates them to achieve processing of the aluminum alloy workpiece 14. Figure 9 Schematic diagram of the structure of the aluminum alloy workpiece 14, which is a thin-walled structural part with radially and circumferentially concave side walls.

[0071] In this embodiment, the first motor 6 and the second motor 2 are both two-phase hybrid stepping motors. The bearing shaft 24 is a one-way thrust bearing shaft 24, the first bearing 22 is a one-way thrust cylindrical roller bearing, and the second bearing 25 is a deep groove ball bearing.

[0072] An aluminum alloy dieless progressive forming device in this embodiment can realize the dieless progressive forming of the aluminum alloy workpiece 14 surface. Combined with the radial flipping and circumferential rotation functions of the device, it can realize the integrated forming of the radial inward concave side wall and the circumferential inward concave side wall of the thin-walled structural part, so as to reduce the clamping error of such parts and broaden the processing range of the dieless progressive forming process.

[0073] Example 2

[0074] This embodiment 2 describes a dieless incremental forming method for aluminum alloys, which is based on the dieless incremental forming device for aluminum alloys in embodiment 1. The method comprises the following steps:

[0075] Step 1: First remove the pressing plate 11 from the forming plate 21, then fix the aluminum alloy workpiece 14 between the pressing plate 11 and the forming plate 21 and lock them with bolts.

[0076] Step 2: The operator operates the CNC unit. The CNC unit controls the first motor 6 in the first drive assembly to drive the support plate 16 to swing, thereby driving the aluminum alloy workpiece 14 to swing; the CNC unit controls the second motor 2 in the second drive assembly to drive the rotating support plate 13 to rotate, thereby driving the aluminum alloy workpiece 14 to rotate; the CNC unit controls the piston rod of the oil cylinder 10 in the lifting assembly to move up and down, thereby driving the aluminum alloy workpiece 14 to move up and down.

[0077] Step 3: At the same time, the numerical control unit controls the movement of the tool head 26 to perform precise processing on the aluminum alloy workpiece 14 .

[0078] Step 4: After the aluminum alloy workpiece 14 is processed, the bolts on the pressing plate 11 are removed to separate the pressing plate 11 from the forming plate 21 and remove the aluminum alloy workpiece 14.
