Embodiment Construction

[0017] Such as figure 1 As shown, the whole process of steel ball production is: selection of raw materials, light drawing, cold pier pressure, stress relief, light ball, soft grinding, heat treatment, hard grinding, surface strengthening, preliminary research, cleaning and polishing to remove oil, flaw detection, and fine grinding. Second, the appearance of the finished product is cleaned, oiled and packaged. Except for the surface strengthening process in the above steps, other processes are commonly used processes, so the description will not be repeated here.

[0018] Such as figure 2 As shown, the specific process of the above-mentioned surface strengthening process is as follows: first, a. Hard grinding the steel ball after heat treatment; b. Flowing the hard ground steel ball into the roller of the steel ball surface strengthening press through the guide groove; c. Accelerate the rolling of the roller of the steel ball surface strengthening press machine, and the ste...

Abstract

The invention discloses a steel ball surface strengthening process. The steel ball surface strengthening process is characterized in that austenite left on a steel ball is irregularly stricken at a certain speed through a roller after the steel ball is treated through quenching and tempering, and the austenite left on the steel ball is induced into martensite by phase transformation under the pressure effect of striking. The surface hardness of the steel ball is enhanced due to the change, and the surface compressing stress is increased, so as to provide conditions for meeting the requirements of surface roughness. So the processing quality of the steel ball is enhanced, and especially enhancing the dynamic performance of the steel ball is an effective way for producing steel balls with low noise.

Description

Technical field: [0001] The invention relates to a steel ball surface strengthening process, in particular to a steel ball surface strengthening process with high surface hardness of steel balls formed by non-directional and irregular impact. Background technique: [0002] In the ordinary steel ball processing process, it is directly ground after hard grinding, and the surface hardness of the steel ball is uneven and low, and it is very easy to cause surface grinding when it is squeezed and ground by a cast iron disc during the primary grinding process Unevenness makes it difficult to improve accuracy. Contents of the invention [0003] The invention relates to a process for strengthening the surface of steel balls formed by non-directional and irregular impact with high surface hardness. [0004] In order to solve the above technical problems, the innovative point of a steel ball surface strengthening process of the present invention is that the steps of the steel ball s...
