Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing, and particularly relates to a bearing forming mandrel. Background Art

[0002] In the process of bearing ring production and processing, a mandrel is placed in a mold for die casting. However, in order to ensure roundness, the current mandrels are all cylindrical, and the workpiece to be processed itself has a certain arc, resulting in the bottom of the workpiece warping up when the upper and lower molds are closed, and there is a problem of forming errors, wasting materials, as Figures 1 to 2 shown. Summary of the Invention

[0003] According to an embodiment of the utility model, a bearing forming mandrel is provided, comprising: a mandrel body, which is composed of a fixed section and a forming section connected end to end. The forming section is cylindrical, and cutting planes are provided on both sides of the forming section.

[0004] Further, the fixed section is cylindrical, and the diameter of the fixed section is smaller than that of the forming section.

[0005] Further, the axial centerlines of the fixed section and the forming section are on the same straight line.

[0006] Further, an installation hole is provided at the end of the fixed section.

[0007] Further, the mandrel body is integrally formed.

[0008] Further, the material of the mandrel body is Cr12MoV.

[0009] According to a bearing forming mandrel of an embodiment of the utility model, cutting planes are provided on both sides of the forming section, which can reduce the arc of the bottom of the workpiece warping up when the upper and lower molds are closed, so that the bottom of the workpiece can stably enter the lower mold, ensuring the effectiveness of production and processing.

[0010] It should be understood that both the foregoing general description and the following detailed description are exemplary and are intended to provide further explanation of the claimed technology. Brief Description of the Drawings

[0016] The following will describe in detail the preferred embodiments of the present utility model in conjunction with the accompanying drawings and further elaborate on the present utility model.

[0017] First, in combination with Figures 3 to 5 Describe a bearing forming mandrel according to an embodiment of the present utility model, which is used for the forming processing of bearing rings and has a wide range of application scenarios.

[0018] As Figures 3 to 5 shown, a bearing forming mandrel according to an embodiment of the present utility model has a mandrel body, which is composed of a fixed section 12 and a forming section 11 connected end to end. The forming section 11 is cylindrical, and cutting planes 13 are provided on both sides of the forming section 11. When the upper and lower dies are closed, the arc at the bottom of the workpiece is reduced, and the bottom of the workpiece stably enters the lower die, ensuring the effectiveness of production and processing.

[0019] Furthermore, as Figures 3 to 5 shown, the fixed section 12 is cylindrical, and the diameter of the fixed section 12 is smaller than that of the forming section 11. The axial centerlines of the fixed section 12 and the forming section 11 are on the same straight line.

[0020] Furthermore, in this embodiment, as Figure 5 shown, an installation hole 14 is provided at the end of the fixed section 12 for fixing the mandrel.

[0021] Furthermore, in this embodiment, the mandrel body is integrally formed, and the material of the mandrel body is Cr12MoV to ensure strength and reliability.

[0022] Above, with reference to Figures 3 to 5 described a bearing forming mandrel according to an embodiment of the present utility model. Cutting planes 13 are provided on both sides of the forming section 11, which can reduce the arc of the bottom of the workpiece from warping when the upper and lower dies are closed, enabling the bottom of the workpiece to stably enter the lower die and ensuring the effectiveness of production and processing.

[0023] It should be noted that in this specification, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising..." does not exclude the presence of additional identical elements in the process, method, article or device comprising said element.

[0024] Although the content of the present utility model has been introduced in detail through the above preferred embodiments, it should be recognized that the above description should not be construed as a limitation of the present utility model. After those skilled in the art have read the above content, various modifications and alternatives to the present utility model will be obvious. Therefore, the protection scope of the present utility model should be defined by the appended claims.
