[0027] The embodiment of the utility model provides a sheet rounding device.

[0028] See also Figure 3 , including a working platform 1, a slide groove 12 is opened on the top surface of the working platform 1, and a sliding support rod 14 is fixedly connected to the inner wall of the slide groove 12. The sliding support rod 14 has an auxiliary supporting effect on the threaded slider 151, which can enable the threaded slider 151 to remain stable in a sliding or stationary state, and prevent the threaded slider 151 from shaking and affecting the auxiliary rolling effect of the support roller 153.

[0029] See also Figure 1 , Figure 2 and Figure 3 The inner wall of the slide 12 is rotatably connected with a bidirectional threaded rod 13, and a servo motor 16 is fixedly installed on the outer surface of the working platform 1. The bidirectional threaded rod 13 and the servo motor 16 are both prior arts, and will not be described in detail in this application. The bidirectional threaded rod 13 is fixedly connected with the output shaft of the servo motor 16. When the servo motor 16 is started, it can drive the bidirectional threaded rod 13 to rotate inside the slide 12. A fixing plate for fixing the servo motor 16 is installed on the outer surface of the working platform 1 to prevent the servo motor 16 from rotating during operation.

[0030] Two supporting mechanisms 15 are arranged above the working platform 1, and the supporting mechanism 15 includes a threaded slider 151, and the threaded slider 151 is slidably connected to the slide groove 12, and the threaded slider 151 is threadedly connected to the bidirectional threaded rod 13. The rotation of the bidirectional threaded rod 13 can drive the two threaded sliders 151 to move closer to or away from each other inside the slide groove 12, and the sliding of the threaded slider 151 can adjust the distance between the two supporting rollers 153, so that the supporting rollers 153 can provide support for rolling operations of different sizes.

[0031] The threaded slider 151 is slidably connected to the sliding support rod 14, and the top surface of the threaded slider 151 is fixedly connected to the support frame 152, and the internal rotation of the support frame 152 is connected to the support roller 153. Through the setting of the rolling roller 6 and the two support rollers 153, the principle of three points forming a circle is utilized, and the plate is deformed into a cylindrical finished product through rotational extrusion, thereby completing the rounding operation.

[0032] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The top surface of the working platform 1 is fixedly connected with a lifting support box 2, and the lifting support box 2 is slidably connected with a lifting sliding plate 3 inside. Two hydraulic lifting columns 11 are fixedly installed on the inner bottom wall of the lifting support box 2. The top of each hydraulic lifting column 11 is fixedly connected with the lifting sliding plate 3. The hydraulic lifting column 11 is a prior art and will not be described in detail in this application. The hydraulic lifting column 11 uses hydraulic oil as a driving medium and drives the column to rise or fall through a built-in hydraulic power unit, thereby pushing the lifting sliding plate 3 to rise and fall inside the lifting support box 2. The two hydraulic lifting columns 11 work synchronously, which can keep the lifting sliding plate 3 stable during the lifting process.

[0033] The lifting support box 2 is fixedly connected to a slide rail 10, to which the lifting sliding plate 3 is slidably connected. The slide rail 10 protects the lifting and sliding of the lifting sliding plate 3 to prevent the lifting and sliding plate 3 from lateral deviation during the sliding process and affecting the rolling operation of the rolling roller 6.

[0034] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 A servo motor 4 is fixedly installed on the outer surface of the lifting sliding plate 3, and a transmission shaft 5 is rotatably connected inside the servo motor 4. The transmission shaft 5 passes through the lifting sliding plate 3 and is rotatably connected to the lifting sliding plate 3. The servo motor 4 is a prior art and will not be described in detail in this application. The servo motor 4 can drive the transmission shaft 5 to rotate when started, and the rotation of the transmission shaft 5 can provide power for the rolling operation of the rounding roller 6. A fixing plate for fixing the servo motor 4 is installed on the outer surface of the lifting sliding plate 3 to prevent the servo motor 4 from self-rotating during operation.

[0035] See also Figure 5 The outer surfaces of the transmission shaft 5 and the rounding roller 6 are both provided with threaded holes 7. The setting of the threaded holes 7 can increase the connection stability between the threaded nails 8 and the transmission shaft 5 and the rounding roller 6, thereby preventing the rounding roller 6 from shaking during the rounding operation.

[0036] The internal thread of the threaded hole 7 is connected with a threaded nail 8, and one end of the threaded nail 8 is threadedly connected with a nut 9. A groove compatible with the rounding roller 6 is opened at the end of the transmission shaft 5 close to the rounding roller 6. The staff inserts the rounding roller 6 into the groove, and then rotates the threaded nail 8 to pass the threaded nail 8 through the rounding roller 6 and the transmission shaft 5. Finally, the transmission shaft 5 and the rounding roller 6 are fixedly connected together through the nut 9. At this time, the rotation of the transmission shaft 5 can drive the rounding roller 6 to rotate. When disassembling, just remove the nut 9 from the threaded nail 8 and then pull the threaded nail 8 out of the threaded hole 7.

[0037] See also Figure 1 , Figure 2 and Figure 5 A rounding roller 6 is arranged on the outside of the lifting sliding plate 3. When the rounding roller 6 is fixedly connected to the transmission shaft 5, the lifting and lowering of the lifting sliding plate 3 can drive the transmission shaft 5 to lift and lower, thereby adjusting the relative distance between the rounding roller 6 and the supporting roller 153, which is convenient for rounding the plates with different diameter requirements. The rotation of the transmission shaft 5 can drive the rounding roller 6 to rotate, thereby rounding the plates placed on the supporting roller 153.

[0038] When the utility model is in use: the staff first adjusts the device according to the cylinder diameter to be processed, and starts the servo motor 16. The servo motor 16 starts to drive the bidirectional threaded rod 13 to rotate. The rotation of the bidirectional threaded rod 13 drives the threaded slider 151 to slide inside the slide groove 12, thereby changing the distance between the two support rollers 153, and then the plate to be rolled is placed on the two support rollers 153, and then the servo motor 14 is started. Under the transmission action of the transmission shaft 5, the rolling roller 6 will start to rotate, thereby rolling the plate, and finally starting the hydraulic lifting column 11. The hydraulic lifting column 11 pushes the lifting sliding plate 3 to rise and fall inside the lifting support box 2. The lifting and falling of the lifting sliding plate 3 can drive the transmission shaft 5 to rise and fall, thereby adjusting the height of the rolling roller 6, so that the rolling roller 6 can roll the plate placed on the support roller 153 while rotating.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
