Technical Field

[0001] The utility model relates to the field of slewing bearing shaping, in particular to a slewing bearing shaping device. Background Art

[0002] The slewing bearing shaping device is a device used to adjust and optimize the performance of the slewing bearing. The slewing bearing itself is a large bearing that can withstand comprehensive loads. The shaping device uses specific processes and technical means to accurately shape the slewing bearing to ensure that it can simultaneously withstand large axial and radial loads and overturning moments, thereby meeting the needs of various complex working conditions and improving the stability and reliability of mechanical equipment.

[0003] Chinese patent publication number CN114951357B discloses a slewing bearing shaping device and method. The device comprises a shaping plate, a shaping platform, and a shaping rod. By disposing two semi-circular shaping plates, the two shaping plates move relative to each other and simultaneously compress the outer ring of the slewing bearing. This allows the outer ring of the slewing bearing to be shaped in a single extrusion, significantly shortening the shaping time. The provision of a loading and unloading assembly allows the shaping of the outer ring of the slewing bearing to be performed continuously without requiring significant human intervention, significantly improving the production efficiency of the outer ring of the slewing bearing.

[0004] The slewing bearing shaping device of the above patent presses the slewing bearing material by clamping it relative to each other through a pair of shaping plates during shaping. However, the pressing of the shaping plates alone can easily cause the pressed material to deform, and the pressing position needs to be adjusted repeatedly, resulting in reduced pressing efficiency and failure to press into the desired circle.

[0010] Preferably, the front and rear ends of one of the extrusion rings are provided with welded and fixed wrapping pieces.

DETAILED DESCRIPTION

[0019] The application will be further described below in conjunction with specific embodiments.

[0020] Embodiment 1

[0021] As Figure 1 shown, the rotary supporting shaping device of the embodiment includes a base 1, one side of the lower end of the base 1 is provided with a transmission belt 2, after transmission by transmission rollers inside the transmission belt 2, the transmission belt 2 will drive the extruded and shaped rotary supporting material to move horizontally, and the rotary supporting material is actively discharged to the outside of the base 1, and the active discharge facilitates the continuous processing and continuous shaping of the rotary supporting material.

[0022] Among them, the upper end of the base 1 is provided with a tray 4 on both sides, bidirectional screw rods 3 are provided through the front and rear ends outside the two trays 4, and the bidirectional screw rods 3 are threadedly connected with the through positions of the trays 4, the bidirectional screw rods 3 rotate after the output of the motor, and the rotation of the bidirectional screw rods 3 can drive the relative movement of the two trays 4, and the opposite movement of the two trays 4 can make the rotary supporting material placed on the upper end fall down, so that the material falls on the transmission belt 2 on the lower end.

[0023] In addition, the upper end of the two trays 4 is provided with an extrusion ring 6, and the two extrusion rings 6 are mirror set on the upper end of the base 1, and the relative movement of the pair of extrusion rings 6 can pressurize the rotary supporting material between them.

[0024] In order to improve the stability of the pair of extrusion rings 6 when combined, as Figure 1 and Figure 2As shown, wrapping pieces 7 are provided at both the front and rear ends of one of the extrusion rings 6, and the wrapping piece 7 is welded and fixed to one of the extrusion rings 6. When the pair of extrusion rings 6 move relative to each other, one of the extrusion rings 6 is wrapped around the front and rear ends of the other extrusion ring 6 by the wrapping piece 7. When the pair of extrusion rings 6 are combined, the wrapping piece 7 is wrapped around the front and rear ends between the pair of extrusion rings 6. The wrapping piece 7 can improve the stability of the extrusion rings 6 when they are combined.

[0025] In order to further improve the stability of the lateral movement of the extrusion ring 6, as shown in FIG. Figure 2 As shown, a first hydraulic telescopic rod 5 is provided at the middle position of the extrusion ring 6 away from the middle position of the base 1, and the outer wall of the first hydraulic telescopic rod 5 is fixedly connected to the upper end of the tray 4 by bolts. The telescopic position of the first hydraulic telescopic rod 5 is welded and fixed to the outer wall of the extrusion ring 6. After being fixed by the bolts, the first hydraulic telescopic rod 5 can push the extrusion ring 6, pushing and causing the extrusion ring 6 to move relatively.

[0026] like Figure 1 and Figure 3 As shown, a connecting block 11 is provided in the middle position between the two extrusion rings 6. Four second hydraulic telescopic rods 12 are evenly distributed around the outside of the connecting block 11. A roller 13 is provided at one end of the second hydraulic telescopic rod 12, and the upper end of the roller 13 is rotatably connected to one end of the second hydraulic telescopic rod 12. The roller 13 can be pushed by the second hydraulic telescopic rod 12 to move toward the inner wall of the slewing bearing squeezed by the extrusion ring 6. As the second hydraulic telescopic rod 12 is extended and retracted, it can adapt to slewing bearing materials of different calibers.

[0027] In addition, the other end of the second hydraulic telescopic rod 12 is welded and fixed to the outer wall of the connecting block 11. After independently outputting the connecting block 11, the surrounding rollers 13 can be synchronously driven to rotate. After the rollers 13 are attached to the inner wall of the slewing support material, they can further plasticize the slewing support after rotation.

[0028] In order to reserve the middle position between a pair of extrusion rings 6 when placing the slewing support material, Figure 1 and Figure 3 As shown, a pair of brackets 10 are provided on one side of the outer portion of the base 1, a transmission frame 9 is provided between the pair of brackets 10, and the transmission frame 9 is rotatably connected to the brackets 10. After the motor outputs the transmission frame 9, the transmission frame 9 can be rotated between the pair of brackets 10;

[0029] The upper end of the connecting block 11 passes through the transmission frame 9 and is rotatably connected to the transmission frame 9. After the transmission frame 9 rotates between a pair of brackets 10, the position of the second hydraulic telescopic rod 12 and the roller 13 can be adjusted. After the position of the roller 13 is adjusted, it is easy to unfold and place the slewing support material.

[0030] Example 2

[0031] In order to facilitate the slewing support material to fall from between the pair of extrusion rings 6, both extrusion rings 6 are provided with a drop hole 8 at the middle position toward the upper end of the base 1. The reserved drop hole 8 can facilitate the slewing support material placed on the upper end to fall after the tray 4 moves horizontally;

[0032] Among them, such as Figure 1 、 Figure 3 and Figure 4 As shown, a support sheet 15 is laterally arranged in the middle position inside the transmission belt 2, and shock absorbers 14 are arranged at the four corners of the lower end of the support sheet 15, and the two ends of the shock absorber 14 are respectively welded to the support sheet 15 and the base 1. The slewing bearing material falling from between the two extrusion rings 6 will fall and be contacted by the transmission belt 2, and the transmission belt 2 will be concave toward the support sheet 15 after being impacted. After the support sheet 15 is impacted, the shock absorber 14 will cushion the impact force, thereby avoiding damage to the transmission belt 2 caused by the falling of the slewing bearing material.

[0033] Working principle: When using the device and placing the heat-treated slewing bearing raw material between the two pallets 4, start the first hydraulic telescopic rod 5. The extension and contraction of the two first hydraulic telescopic rods 5 push the extrusion rings 6 respectively. The two extrusion rings 6 are relatively fitted together, and one of the extrusion rings 6 is slidably wrapped around the outside of the other extrusion ring 6 through the wrapping sheet 7. As the two extrusion rings 6 move relative to each other and squeezed, the motor drives the transmission frame 9 to rotate in a circle with the bracket 10 as the center. The rotation of the transmission frame 9 can drive the second hydraulic telescopic rod 12 to move through the connecting block 11. The second hydraulic telescopic rod 12 will drive the corresponding roller 13 at one end to move between the two extrusion rings 6. The roller 13 can be pushed by the extension and contraction of the second hydraulic telescopic rod 12, so that the roller 13 contacts the inner wall of the slewing bearing raw material after heat treatment. The connecting block 11 can drive the roller 13 to rotate after the output of the upper end motor. The rotation of the roller 13 and the extrusion of a pair of extrusion rings 6 can complete the shaping of the slewing bearing material.
