Description

Technical Field

[0001] The utility model relates to the technical field of ion nitriding equipment, in particular to an electrode sealing insulation device for ion nitriding equipment. Background Art

[0002] Ion nitriding is a chemical heat treatment method for strengthening metal surfaces. It is widely used in cast iron, carbon steel, alloy steel, stainless steel and titanium alloy. After ion nitriding, the hardness of the material surface can be significantly improved, making it have high wear resistance, fatigue strength, corrosion resistance and burn resistance. Ion nitriding, also known as glow nitriding, is carried out using the principle of glow discharge.

[0003] For example, the electrode sealing and insulating device of an ion nitriding equipment with the authorization announcement number "CN219526762U" is connected to the electrode fixing flange, PTFE flange, welding flange and PTFE flange by bolts at the bottom of the furnace body, which is convenient for disassembly and replacement. A screw insulation sleeve is provided outside the screw, a ceramic sleeve is provided between the furnace body and the internal electrode rod, and a wiring PTFE sleeve is provided at the connection between the electrode rod and the cathode line of the power supply to enhance the insulation effect and improve safety. A water cooling sleeve is provided at the lower end of the furnace body, which has a good cooling effect. However, the electrode sealing and insulating device of the ion nitriding equipment is fixed by the operator turning the bolts multiple times to fix the electrode fixing flange, PTFE flange, welding flange and PTFE flange. Since the operator needs to fix it manually, it takes a lot of effort to ensure that it will not shake during processing, thereby increasing manual labor. At the same time, the electrode sealing and insulating device of the ion nitriding equipment cools the furnace body through the water cooling sleeve. Since the cooling is performed through the water cooling sleeve, it is easy to cause the cooling water temperature in the water cooling sleeve to rise, so it takes a long time to cool the furnace body, thereby reducing work efficiency.
