The upper end of the adapter rod 61 is detachably fixed to the mounting seat 4. The first flanging wheel 6 and the limiting wheel 3 need to be used in cooperation, so they need to be mounted or dismounted at the same time. The rotation shafts of the limiting wheel 3, the rotary table 1 and the first flanging wheel 6 are located on the same virtual plane. In other words, when the X-axis 51 drives the first flanging wheel 62 to move, the rotation shaft of the first flanging wheel 6 moves along the virtual plane where the rotation shafts of the limiting wheel 3 and the rotary table 1 are located.

[0059] The second flanging wheel 7

[0060] Referring to Figure 7 、 Figure 8 The second flanging wheel 7 shown in the drawings can also be detachably arranged on the mounting seat 4, and the rotation axis of the second flanging wheel 7 and the rotation axis of the rotary table 1 are perpendicular to each other. The second flanging wheel 7 is provided with an annular forming groove 71 on the peripheral surface.

[0061] The working principle of the device will be briefly described in combination with the device structure as follows:

[0062] Vertical flanging of the lower frame

[0063] 1. When the first flanging wheel 6 and the limiting wheel 3 are used to perform vertical flanging on the lower frame, the cylinder is sleeved on the support petals 11, and then the expansion core 2 is inserted into the support petals 11 to make the support petals 11 open outward, and the cylinder is fixed by the inner support;

[0064] 2. Then the servo motor 12 drives the rotary table 1 to rotate, thereby driving the cylinder to rotate;

[0065] 3. The XY-axis linear module 5 drives the mounting seat 4 to move, so that the first flanging wheel 6 on the mounting seat 4 is inserted into the cylinder, and the peripheral surface of the first flanging wheel 6 abuts against the inner side surface of the cylinder edge on the rotary table 1. At this time, the peripheral surface of the limiting wheel 3 abuts against the outer side surface of the cylinder. There is a height difference between the lower end surface of the first flanging wheel 6 and the upper end surface of the limiting wheel 3, and the height difference cooperates with the wall thickness of the cylinder.

[0066] 4. The XY-axis linear module 5 drives the mounting seat 4 to further translate, so that the first flanging wheel 6 moves towards the limiting wheel. At this time, the cylinder is bent by the compression of the first flanging wheel 6, and the remaining part can be blocked by the peripheral surface of the limiting wheel 3;

[0067] 5. The first flanging wheel 6 is further translated until the cylinder edge is clamped between the first flanging wheel 6 and the end surface of the limiting wheel. At this time, the clamped edge of the cylinder is 90 degrees vertically folded; 6. The servo motor 12 drives the rotary table 1 to rotate, and the cylinder edge is repeatedly clamped by the end surface of the first flanging wheel 6 and the end surface of the limiting wheel 3 until it is formed.

[0068] Flanging of the lower frame

[0069] 1. When the second flanging wheel 7 is used to perform flanging on the upper frame, the cylinder is sleeved on the support petals 11, and then the expansion core 2 is inserted into the support petals 11 to make the support petals 11 open outward, and the cylinder is fixed by the inner support;

[0070] 2. Then the servo motor 12 drives the rotary table 1 to rotate, thereby driving the cylinder to rotate;

[0071] 3. The XY-axis linear module 5 drives the mounting seat 4 to move, so that the annular forming groove on the peripheral surface of the second flanging wheel 7 on the mounting seat 4 abuts against the upper end of the cylinder on the rotary table 1;

[0072] 4. The XY axis linear module 5 drives the mounting base 4 to move further, so that the second flanging wheel 7 moves slightly in the radial direction of the turntable. Moving outward will cause the edge of the cylinder to curl outward, and moving inward will cause the edge of the cylinder to curl inward.

[0073] 5. The servo motor 12 drives the turntable 1 to rotate, and the edge of the cylinder is repeatedly pressed by the second flanging wheel 7 until it is formed.

[0074] Upper frame expansion tube

[0075] 1. When the first flange wheel 6 and the limiting wheel 3 are used to expand the tube of the upper frame, the cylinder is fitted on the support petal 11. Then the expansion core 2 is inserted into the support petal 11, causing the support petal 11 to open outward and the cylinder to be fixed by the inner support.

[0076] 2. Then, servo motor 12 drives turntable 1 to rotate, which in turn drives the cylinder to rotate;

[0077] 3. The XY axis linear module 5 drives the mounting base 4 to move, causing the first flanging wheel 6 on it to insert into the cylinder. The circumferential surface of the first flanging wheel 6 presses against the inner side of the cylinder edge on the turntable 1. At this time, the circumferential surface of the limiting wheel 3 abuts against the outer side of the cylinder. There is a height difference between the lower end face of the first flanging wheel 6 and the upper end face of the limiting wheel 3, and this height difference matches the cylinder wall thickness.

[0078] 4. The XY axis linear module 5 drives the mounting base 4 to move further, causing the first flanging wheel 6 to move towards the limit wheel. At this time:

[0079] The portion of the cylinder corresponding to the lower end face of the first flange wheel 6 is pressed and bent, and then pressed against the upper end face of the limiting wheel 3;

[0080] The portion of the cylinder corresponding to the first flange wheel 6 is compressed and expands outward;

[0081] The rest of the cylinder can be stopped by the three circumferential surfaces of the limiting wheel;

[0082] 5. The servo motor 12 drives the turntable 1 to rotate, and the edge of the cylinder is repeatedly clamped by the end face of the first flanging wheel 6 and the end face of the limiting wheel 3 until it is formed.

[0083] Press-fit

[0084] 1. When the first flange wheel 6 and the limiting wheel 3 are used to press and fix the upper and lower frames together, it is similar to... Figure 1 As shown, the upper frame is fitted onto the support petal 11, with one end of the expander tube facing outwards; and the screen and lower frame are bonded together and placed inside the expander tube end of the upper frame.

[0085] 2. Then the expansion core 2 is inserted into the support petal 11, causing the support petal 11 to open outwards, and the upper frame is fixed by the inner support; 3. Then the servo motor 12 drives the turntable 1 to rotate, which in turn drives the upper frame and the lower frame and the screen to rotate together.

[0086] 4. The XY axis linear module 5 drives the mounting base 4 to move, so that the circumference of the first flange wheel 6 on it presses against one end of the upper frame expansion tube on the turntable 1.

[0087] 5. The XY axis linear module 5 drives the mounting base 4 to move further, causing the first flange wheel 6 to move towards the axis of the turntable 1. The upper frame expansion end is pressed inward and bent against the vertical flange of the lower frame.

[0088] 6. The servo motor 12 drives the turntable 1 to rotate, and the upper frame expansion end part is repeatedly pressed by the end face of the first flanging wheel 6 onto the vertical flanging of the lower frame until it is formed.

[0089] Compared with the prior art, the beneficial effects of this utility model are:

[0090] It can perform the entire screen forming operation, including edge rolling and flanging, vertical flanging, tube expansion and pressing connection, on a single machine by changing the flanging wheel;

[0091] When the first flanging wheel abuts against the inner side of the cylinder, the expansion of the tube and the vertical flanging process can be achieved by controlling the stroke of the first flanging wheel. During vertical flanging, the first flanging wheel and the limiting wheel cooperate to clamp the edge of the cylinder, causing this part to fold vertically relative to the cylinder body. By rotating the cylinder multiple times, the vertically folded edge is repeatedly bent, thus maintaining the vertically folded state of the cylinder edge and reducing the impact of flanging springback on the cylinder's flanging quality. This also reduces the roughening of the cylinder during the flanging process, thereby effectively improving the flanging quality of the cylinder.
