DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a bearing flange forging die.

[0024] like Figures 1-3 As shown, it includes a mold body 1 and an upper pressing block 2, and a forging cylinder 3 is connected to the upper pressing block 2. A mounting cavity is arranged in the mold body 1, and a forging mold is installed in the mounting cavity. The forging mold includes an inner film sleeve 4, a positioning support ring 5 and a forging chassis 6. The inner film sleeve 4 is fixed in the mounting cavity, and the upper pressing block 2 is slidingly arranged in the inner film sleeve 4 with a concave-convex fit. The positioning support ring 5 is fixed in the middle of the mounting cavity, and the positioning support ring 5 abuts against the bottom of the forging chassis 6. The forging chassis 6 extends into the inner film sleeve 4. A demoulding mechanism is connected between the forging chassis 6 and the mold body 1, and the demoulding mechanism includes a demoulding sleeve 7, a support spring 8 and a support guide rod 9, the demolding sleeve 7 is fixed at the bottom of the forging chassis 6, the lower end of the supporting guide rod 9 is fixed at the bottom of the mold body 1, and the upper end is slidably inserted in the demolding sleeve 7, the supporting spring 8 is in contact between the demolding sleeve 7 and the supporting guide rod 9, a plurality of vibration guide plates 10 are fixed to the outer wall of the demolding sleeve 7, and a paddle assembly is installed at the bottom of the mold body 1, the paddle assembly is in contact with the vibration guide plate 10, the paddle assembly hits and contacts the vibration guide plate 10, and bends the vibration guide plate 10 until the vibration guide plate 10 is separated from the paddle assembly and reset, and vibration will occur, and the vibration will be transmitted to the flange workpiece on the forging chassis 6, so that a vibration difference is formed between the flange workpiece and the inner membrane sleeve 4, and the demolding effect is achieved through mutual vibration.

[0025] like Figure 4 , 5As described above, the paddle assembly includes a rotating ring 11 rotatably connected to the bottom of the mold body 1, a driven gear ring 12 concentrically arranged at the upper end of the rotating ring 11, a plurality of paddle rods 13 connected between the rotating ring 11 and the driven gear ring 12, and a driving gear 14 meshing with the driving gear ring. A rotating ring groove is formed at the bottom of the mold body 1, and the rotating ring 11 is slidably inserted into the rotating ring groove. A driving motor 15 is connected to the driving gear ring, and the driving motor 15 is fixed on the mold body 1. The paddle rod 13 abuts against the end of the vibration guide plate 10. The set height of the driven gear ring 12 is higher than the upper edge of the vibration guide plate 10. The driving motor 15 drives the whole paddle assembly to rotate, and the paddle rod 13 can press the vibration guide plate 10, causing the vibration guide plate 10 to bend. When the vibration guide plate 10 bends to a certain extent, the vibration guide plate 10 will disengage from the paddle rod 13, and the vibration guide plate 10 will reset, generating vibration and transmitting the vibration to the forging chassis 6.

[0026] Further, the demolding sleeve 7 is arranged at the axial center position of the forging chassis 6, and the rotating ring groove is eccentrically arranged at the bottom of the mold body 1. The eccentrically arranged paddle assembly makes the distances between the circumferentially distributed paddle rods 13 and the demolding sleeve 7 different, that is, the distances between the paddle rods 13 and the end of the vibration guide plate 10 are different. After the vibration guide plate 10 resets, the vibration frequency and amplitude are also different.

[0027] As Figure 1 , 2 As shown, the demolding sleeve 7 includes a forging inner cylinder and a flange ring plate integrally formed. The forging inner cylinder is slidably connected inside the installation cavity, and the flange ring plate is installed on the upper edge of the mold body 1. A plurality of adjusting screws 16 are circumferentially distributed on the upper edge of the mold body 1. The adjusting screws 16 are slidably inserted through the flange ring plate, and adjusting nuts 17 are threadedly connected to the adjusting screws 16. The adjusting nuts 17 abut against the upper side of the flange ring plate. An adjusting spring 18 is sleeved outside the adjusting screw 16, and the adjusting spring 18 abuts between the upper edge of the mold body 1 and the flange ring plate. The outer edge of the adjusting nut 17 is set as a synchronous gear, and a synchronous gear ring 19 is rotatably connected to the flange ring plate. The circumferentially distributed plurality of adjusting nuts 17 are evenly meshed with the synchronous gear ring 19. A driving handle is arranged on the outside of the synchronous gear ring 19. Rotating the synchronous gear ring 19 can make the circumferentially distributed plurality of adjusting nuts 17 rotate synchronously, and can keep the tightness of the adjusting spring 18 consistent, avoiding the deviation of the demolding sleeve 7 and causing defects in the forming of the flange workpiece.

[0028] Working principle:

[0029] In the present utility model, the forging cylinder 3 can drive the upper pressing block 2 to slide downward in the inner film sleeve 4, and a flange workpiece is forged and formed between the upper pressing block 2, the inner film sleeve 4 and the forging chassis 6. After the forging is completed, the upper pressing block 2 is reset by the forging cylinder 3. The driving gear ring rotates in the rotating ring groove by the driving motor 15. During the rotation, the dial rod 13 abuts against the vibration guide plate 10 and causes the vibration guide plate 10 to bend. The vibration guide plate 10 will break away from the dial rod 13 and reset, and the vibration guide plate 10 generates high-frequency vibration. The high-frequency vibrating vibration guide plate 10 transmits the vibration to the flange workpiece through the demoulding sleeve 7 and the forging chassis 6. Due to the extrusion of the adjusting spring 18, the inner film sleeve 4 as a whole will not vibrate synchronously with the flange workpiece. The vibration difference causes the flange workpiece to separate from the inner film sleeve 4. Then, the forging chassis 6 slides upward by the support spring 8 to push the flange workpiece out of the inner film sleeve 4, facilitating the demoulding of the flange workpiece.

[0030] In addition, the eccentrically arranged rotating ring groove can enable several dial rods 13 to make the vibration guide plate 10 emit different vibrations with different abutting lengths, so as to adjust the optimal demoulding vibration and ensure the smooth demoulding of the flange workpiece.

[0031] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
