In order to achieve the above purpose, the present application provides the following technical solutions:

the utility model provides a turn to cold-heading blank of ball bowl, the cold-heading blank is made through the cold-heading technology, the cold-heading blank include first cylinder and integrated into one piece in the second cylinder of first cylindrical one end, first cylindrical axis with the collinear of second cylindrical axis, the cylindrical diameter of second is greater than first cylindrical diameter, the second cylinder is kept away from first cylindrical terminal surface is formed with the cylinder groove, the tank bottom in cylinder groove is formed with the circular cone groove that is used for the instrument to process, the axis in circular cone groove with the collinear of axis in cylinder groove.

Preferably, the end of the first cylinder away from the second cylinder is formed with a positioning slot.

Preferably, the junction of the first cylinder and the second cylinder is an arc transition.

Preferably, the second cylinder is formed with a plurality of cut surfaces in a circumferential direction adjacent to an outer circumferential wall of the first cylinder.

This application has following advantage:

the cold heading blank only needs to machine the conical surface of the conical groove through a tool to obtain a final product (the steering ball bowl), and compared with the prior art, the cold heading blank is manufactured through a cold heading process by machining processes such as drilling, turning and milling on a solid steel bar, so that the material consumption is reduced, the machining operation is simple, and the production efficiency is high.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

In the description of the present application: the terms "inner" and "outer" refer to the inner and outer of the respective component profiles; the terms "first," "second," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed that are inherent to such process, method, article, or apparatus or that are added to such process, method, article, or apparatus based on the concepts of the present application.
