Abstract
Description
Technical Field
[0001] This utility model relates to the field of spinning press technology, and more specifically, to a point contact pressure roller structure for a spinning press. Background Technology

Figure 1 The image shows the pressure roller structure of the company's existing spinning machine. In this structure, the spinning machine and the main turntable are in line contact. The advantage of line contact is that the surface of the pressure roller perfectly matches the forming surface of the main turntable, thereby increasing the processing speed. However, because of the line contact, the contact area is increased. Since pressure is proportional to area, this causes excessive pressure on the output shaft of the reducer that drives the main turntable to rotate, shortening the service life of the output shaft.

[0031] Example
[0032] The present invention will now be further described with reference to the accompanying drawings.
[0033] like Figures 2 to 4 As shown, this embodiment provides a point-contact pressure roller structure for a spinning machine, positioned close to the main turntable 10. The main turntable 10 is mounted on the output shaft of the reducer, and the impeller cover 11 is located on the forming surface of the main turntable 10. The structure includes:
[0034] The pressure roller assembly 12 applies force to the forming surface of the impeller cover 11 in a point-contact manner;
[0035] Action component 13 is connected to pressure roller assembly 12. Action component 13 drives pressure roller assembly 12 to move up and down along the center line of main turntable 10.
[0036] The working principle and beneficial effects of the above technical solution are as follows:
[0037] This utility model discloses a point-contact pressure roller structure for a spinning machine. The pressure roller assembly 12 applies force to the forming surface of the impeller cover 11 in a point-contact manner. When the output shaft of the reducer drives the main turntable 10 to rotate, the actuating component 13 drives the pressure roller assembly 12 to move up and down along the center line of the main turntable 10, thereby processing the impeller cover 11 located on the forming surface of the main turntable 10. The point-contact pressure roller structure for a spinning machine provided by this utility model has a novel design for the pressure roller assembly 12, which allows the pressure roller assembly 12 to apply force to the forming surface of the impeller cover 11 in a point-contact manner. Compared with the existing line contact method, this significantly reduces the contact area, reduces the pressure on the output shaft of the reducer, and extends the service life of the output shaft of the reducer.
[0038] In one embodiment, the pressure roller assembly 12 includes:
[0039] The main pressure roller 14 is arranged in a disc-shaped structure and makes point contact with the surface of the main turntable 10.
[0040] Mounting bracket 15, the shaft end of the main pressure roller 14 is rotatably mounted on the mounting bracket 15;
[0041] Two fixing screws 16 are symmetrically installed on the mounting bracket 15.
[0042] The return spring 17 is sleeved on the fixing screw 16;
[0043] Mounting plate 18, flip rod 19 is connected between mounting plate 18 and actuation component 13, fixing screw 16 passes through mounting plate 18 at the end away from mounting bracket 15, and return spring 17 abuts between mounting bracket 15 and mounting plate 18;
[0044] The fixing nut 20 is screwed onto the fixing screw 16.
[0045] The working principle and beneficial effects of the above technical solution are as follows:
[0046] The main pressure roller 14 is designed in a disc shape, so that the main pressure roller 14 makes point contact with the forming surface of the impeller cover 11. The main pressure roller 14 is rotatably mounted on the mounting frame 15, and the mounting frame 15 is connected to the mounting plate 18 through the cooperation of the fixing screw 16 and the fixing nut 20. The mounting plate 18 is mounted on the flipping rod 19. The return spring is sleeved on the fixing screw 16 and abuts between the mounting frame 15 and the mounting plate 18. The setting of the return spring 17 realizes the soft contact between the main pressure roller 14 and the forming surface of the main turntable 10, thereby reducing the pressure on the output shaft of the reducer.
[0047] In one embodiment, the action component 13 includes:
[0048] The lower horizontal sliding seat 21, the flipping rod 19 is rotatably mounted on the lower horizontal sliding seat 21 at the end away from the mounting plate 18;
[0049] Hydraulic cylinder 22, one end of which is mounted on the lower transverse seat 21, and the other end of which is connected to the tilting rod 19 via the side mounting plate 23.
[0050] The working principle and beneficial effects of the above technical solution are as follows:
[0051] The hydraulic cylinder 22 extends and retracts, thereby causing the flipping rod 19 connected to the hydraulic cylinder 22 to flip on the lower transverse seat 21, which in turn causes the main pressure roller 14 mounted on the flipping rod 19 to flip, so that the main pressure roller 14 moves up and down along the center line of the main turntable 10.
[0052] In one embodiment, the fixing nut 20 abuts against the mounting plate 18.
[0053] In one embodiment, the action component 13 further includes:
[0054] The upper fixed frame 24 and the transverse sliding screw 25 are rotatably installed inside the upper fixed frame 24;
[0055] A transverse sliding screw block 26 is sleeved on a transverse sliding screw rod 25, and the bottom end of the transverse sliding screw block 26 is connected to the top end of the lower transverse sliding seat 21.
[0056] A transverse motor 27 is mounted on the upper fixed frame 24, and the output end of the transverse motor 27 is connected to the transverse screw 25.
[0057] The working principle and beneficial effects of the above technical solution are as follows:
[0058] The transverse motor 27 mounted on the upper fixed frame 24 operates, thereby driving the transverse screw 25 mounted on the output end of the transverse motor 27 to rotate. The transverse screw 25 drives the transverse screw block 26 sleeved on it and the lower transverse seat 21 connected to the transverse screw block 26 to slide at the bottom end of the upper fixed frame 24, thereby driving the main pressure roller 14 mounted on the lower transverse seat 21 to move left and right. The main pressure roller 14 moves forward and backward relative to the main turntable 10.
[0059] In one embodiment, the bottom end of the upper fixed frame 24 is provided with a transverse groove, and the bottom end of the transverse screw block 26 is slidably connected in the transverse groove.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
