Description

Technical Field

[0001] The utility model relates to the technical field of metal material surface hardening, in particular to a metal ball material surface nitriding fixture. Background Art

[0002] Nitriding is a chemical heat treatment process that allows nitrogen atoms to penetrate into the surface of a workpiece in a certain medium at a certain temperature. Common processes include liquid nitriding, gas nitriding, and ion nitriding. Ion nitriding is a method of strengthening the metal surface. It uses the glow discharge phenomenon to ionize nitrogen-containing gas to generate nitrogen ions that bombard the surface of the part to heat and nitride it, thereby obtaining an ion chemical heat treatment process for a surface nitrided layer. It is widely used in cast iron, carbon steel, alloy steel, stainless steel, titanium alloy, etc.

[0003] For example, a metal ball surface nitriding fixture with authorization announcement number "CN219689819U" uses an integrated guide column to drive the top layer clamping plate, the bottom layer clamping plate and the middle layer clamping plate to move downward synchronously and clamp the balls placed on top of each layer of annular support seats, which solves the problem of the risk of balls falling during transportation in existing ball nitriding tooling, reduces the difficulty of transportation, and does not affect the nitriding operation. The base used is a hollow base, and the nitriding gas is released to the bottom layer of the supported ball through the base. The low end supported by the lower support screws also achieves the purpose of uniform nitriding relative to other positions, ensuring uniform nitriding of the spherical surface and product quality. However, when the metal ball surface nitriding fixture is used to infiltrate nitrogen into the metal ball, it is necessary to first fix the position of the metal ball before performing subsequent nitrogen infiltration work. The metal ball limit of the equipment needs to be manually operated, which increases the labor force. At the same time, there is no nitrogen infiltration work in the metal ball surface nitriding fixture, and external equipment or manual work is required. The operation of the equipment has limitations. Utility Model Content
