Description

Technical Field

[0001] This application belongs to the field of bearing cage technology, specifically relating to a mold for processing a sunflower-shaped cage. Background Technology

[0002] Sunflower-shaped bearing cages, named for their unique sunflower-like design, are specifically designed for high-load, high-speed bearings. They optimize heat dissipation and improve bearing operational stability. Cages are typically made of high-strength alloys or engineering plastics, adaptable to high temperatures, high speeds, and extreme operating conditions, and are commonly used in aerospace, precision instruments, and high-performance machinery.

[0003] Existing conventional molds for processing sunflower-shaped cages can typically only produce the pockets and the flange structure on one radial side of the main body of the sunflower-shaped cage in a single forming process. The flange structure on the other radial side of the main body of the sunflower-shaped cage requires secondary processing to form. During the secondary processing, quality problems such as cracking or deformation of the flange formed in the first processing often occur. In addition, the structure formed in the first processing needs to undergo surface treatment such as grinding before the secondary processing, resulting in high production costs and low efficiency.

[0004] This shows that existing technologies still have certain shortcomings. Utility Model Content

[0005] In view of this, the present invention aims to propose a mold for processing a sunflower-shaped cage, which can form the flange structure on both radial sides of the annular body of the sunflower-shaped cage in one continuous process, thereby greatly improving the processing efficiency and quality of the sunflower-shaped cage.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] A mold for processing a sunflower-shaped retainer includes an upper mold base, a stamping upper mold, a lower mold base, and a stamping lower mold. The stamping upper mold is disposed at the lower part of the upper mold base, and the stamping lower mold is disposed at the upper part of the lower mold base. The upper mold base moves vertically relative to the lower mold base and simultaneously drives the stamping upper mold and the stamping lower mold to close and open. The stamping upper mold has an upper mold cavity and pre-forming upper mold, forming upper mold, bending upper mold, negative angle bending upper mold, and shaping upper mold disposed in the upper mold cavity. The stamping lower mold has a lower mold cavity and pre-forming lower mold, forming lower mold, bending lower mold, negative angle bending lower mold, and shaping lower mold disposed in the lower mold cavity.

[0008] In the above scheme, the above structure is used to continuously process the cage workpiece to be processed, so as to realize the one-time forming of the flange structure on both sides of the annular body of the sunflower-shaped cage, which greatly improves the processing efficiency and processing quality of the sunflower-shaped cage.

[0009] In a preferred embodiment of this application, both the upper stamping die and the lower stamping die adopt a split structure. The preforming upper die, the forming upper die, the bending upper die, the negative angle bending upper die, and the shaping upper die are detachably connected to the upper die cavity, and the preforming lower die, the forming lower die, the bending lower die, the negative angle bending lower die, and the shaping lower die are detachably connected to the lower die cavity.

[0010] In the above scheme, the use of a split structure makes it easy to replace molds of different sizes and specifications according to actual processing needs, which greatly improves the versatility of the main structure of the mold and helps to reduce production costs.

[0011] In a preferred embodiment of this application, an upper pad and an upper clamping plate are also included. The upper pad and the upper clamping plate are sequentially disposed at the lower part of the upper die base in a vertical direction from top to bottom. A first mounting part is sandwiched between the upper pad and the upper clamping plate. A first mating part corresponding to the first mounting part is provided on the top of the stamping upper die. The upper pad and the upper clamping plate clamp and fix the first mating part in the first mounting part.

[0012] In a preferred embodiment of this application, a lower pad and a lower clamping plate are also included. The lower pad is disposed on the upper part of the lower die base, and the stamping die is disposed on the upper part of the lower pad. A second mounting part is clamped between the lower pad and the lower clamping plate. A second mating part corresponding to the second mounting part is disposed on the lower part of the stamping die. The lower pad and the lower clamping plate clamp and fix the second mating part in the second mounting part.

[0013] In the above scheme, this method can effectively fix the upper and lower molds and also facilitate the disassembly and replacement of the molds.

[0014] As a preferred embodiment of this application, it also includes a stripping assembly, which includes a plurality of ejector rods disposed on the lower stamping die and the plurality of ejector rods being disposed at the pockets of the sunflower-shaped retainer.

[0015] In the above scheme, by setting up a stripping component, the workpiece can be easily removed from the mold after each process is completed, which facilitates the transfer of the workpiece to the next processing step and improves the processing efficiency and quality of the cage.

[0016] In a preferred embodiment of this application, the preforming upper mold, the forming upper mold, the bending upper mold, the negative angle bending upper mold, the shaping upper mold, and the preforming lower mold, the forming lower mold, the bending lower mold, the negative angle bending lower mold, and the shaping lower mold protrusions have smooth surfaces.

[0017] In the above scheme, the above setting method is conducive to ensuring the surface quality of the cage product and avoiding the impact of mold surface quality defects on the quality of the cage product.

[0018] In a preferred embodiment of this application, the corners of both the upper mold base and the lower mold base are chamfered. This arrangement eliminates sharp edges on the mold, preventing injury to operators during mold opening and closing.

[0019] In a preferred embodiment of this application, the surfaces of the preforming upper mold, the forming upper mold, the bending upper mold, the negative angle bending upper mold, and the shaping upper mold are coated with a titanium metal layer.

[0020] In a preferred embodiment of this application, the surfaces of the preforming lower die, the forming lower die, the bending lower die, the negative angle bending lower die, and the shaping lower die are coated with a titanium metal layer.

[0021] In the above solution, the surface strength of the upper and lower molds can be improved by setting a titanium metal layer, which helps to ensure the structural accuracy and surface flatness of the processed sunflower-shaped cage product, thereby improving product quality and consistency.

[0038] Currently, conventional molds for processing sunflower-shaped cages can typically only produce the pockets and the flange structure on one radial side of the main body of the sunflower-shaped cage in a single molding process. The flange structure on the other radial side of the main body of the sunflower-shaped cage requires secondary processing to form. During the secondary processing, quality problems such as cracking or deformation of the flange formed in the first processing often occur. Furthermore, the structure formed in the first processing needs to undergo surface treatment such as grinding before the secondary processing, resulting in high production costs and low efficiency.

[0039] In order to solve the above problems, this application proposes a mold for processing a sunflower-shaped cage.

[0040] Reference Figures 1-5 As shown, the mold for processing a sunflower-shaped cage includes an upper mold base 12, a stamping upper mold 15, a lower mold base 24, and a stamping lower mold 21. The stamping upper mold 15 is located at the lower part of the upper mold base 12, and the stamping lower mold 21 is located at the upper part of the lower mold base 24. The mold base 12 moves vertically relative to the lower mold base 24, simultaneously driving the stamping upper mold 15 and the stamping lower mold 21 to close and open. The stamping upper mold 15 has an upper mold cavity and pre-forming upper mold, forming upper mold, bending upper mold, negative angle bending upper mold, and shaping upper mold disposed in the upper mold cavity. The stamping lower mold 21 has a lower mold cavity and pre-forming lower mold, forming lower mold, bending lower mold, negative angle bending lower mold, and shaping lower mold disposed in the lower mold cavity. In the above scheme, the above structure is used to continuously process the cage workpiece to be processed, realizing the one-time forming of the flange structure on both radial sides of the annular body of the sunflower-shaped cage, greatly improving the processing efficiency and processing quality of the sunflower-shaped cage.

[0041] In a preferred embodiment of this application, both the upper stamping die 15 and the lower stamping die 21 adopt a split structure. The pre-forming upper die, forming upper die, bending upper die, negative angle bending upper die, and shaping upper die are detachably connected to the upper die cavity, while the pre-forming lower die, forming lower die, bending lower die, negative angle bending lower die, and shaping lower die are detachably connected to the lower die cavity. The split structure facilitates the replacement of dies of different sizes and specifications according to actual processing needs, greatly improving the versatility of the main die structure and helping to reduce production costs.

[0042] Furthermore, referring to Figure 3 and Figure 4 As shown, it also includes an upper pad 13 and an upper clamping plate 14. The upper pad 13 and upper clamping plate 14 are sequentially arranged from top to bottom in the vertical direction at the lower part of the upper die base 12. A first mounting portion is clamped between the upper pad 13 and the upper clamping plate 14. A first mating portion corresponding to the first mounting portion is provided on the top of the stamping upper die 15. The upper pad 13 and upper clamping plate 14 clamp and fix the first mating portion in the first mounting portion. (Continue referring to...) Figure 3 and Figure 4As shown, it also includes a lower pad 23 and a lower clamping plate 22. The lower pad 23 is disposed on the upper part of the lower die base 24, and the stamping lower die 21 is disposed on the upper part of the lower pad 23. A second mounting part is clamped between the lower pad 23 and the lower clamping plate 22. A second mating part corresponding to the second mounting part is disposed on the lower part of the stamping lower die 21. The lower pad 23 and the lower clamping plate 22 clamp and fix the second mating part in the second mounting part.

[0043] Preferably, the upper pad 13, upper clamping plate 14, lower pad 23, and lower clamping plate 22 are provided with connecting holes. The upper pad 13 and lower pad 23 are locked together by fastening bolts inserted into the connecting holes. This arrangement can ensure the stability of the connection between the upper pad 13 and upper clamping plate 14 and the lower pad 23 and lower clamping plate 22, and also facilitates subsequent disassembly, replacement, and maintenance.

[0044] Continue to refer to Figure 1 , Figure 2 and Figure 5 As shown, the sunflower-shaped retainer processing mold in this application also includes a guide structure. Preferably, the guide structure includes a plurality of guide posts 3 that are connected to and cooperate with the upper mold base 12 and the lower mold base 24.

[0045] In one example, refer to Figures 1-5 As shown, it also includes a stripping assembly, which includes multiple ejector pins 4 disposed on the lower stamping die 21 and corresponding to the pockets of the hemispherical retainer. In the above solution, by setting the stripping assembly, the workpiece can be easily removed from the die after each processing step is completed, facilitating the transfer of the workpiece for the next processing step, thereby improving the processing efficiency and quality of the retainer.

[0046] In a preferred embodiment of this application, the protrusions of the preforming upper die, forming upper die, bending upper die, negative angle bending upper die, shaping upper die, as well as the preforming lower die, forming lower die, bending lower die, negative angle bending lower die, and shaping lower die have smooth surfaces. This arrangement helps ensure the surface quality of the cage product and prevents surface defects in the mold from affecting the quality of the cage product. Furthermore, the corners of the upper die holder 12 and the lower die holder 24 are chamfered. This arrangement eliminates sharp edges on the molds, preventing injury to operators during mold opening and closing.

[0047] Further preferably, the surfaces of the preforming upper die, forming upper die, bending upper die, negative angle bending upper die, and shaping upper die are coated with a titanium metal layer, as are the surfaces of the preforming lower die, forming lower die, bending lower die, negative angle bending lower die, and shaping lower die. In the above solution, the addition of a titanium metal layer can improve the surface strength of the upper and lower dies, thereby helping to ensure the structural accuracy and surface flatness of the processed sunflower-shaped cage product, and thus improving product quality and consistency.
