Description

Technical Field

[0001] The utility model relates to the technical field of cold heading dies, in particular to a lightweight self-locking nut and a nut cold heading die. Background Art

[0002] Self-locking nuts are designed to lock themselves by friction. Conventional nuts can loosen during use due to vibration and other factors. Self-locking nuts were invented to prevent this. Their primary function is to prevent loosening and vibration. They are used in specialized applications. They generally work by self-locking through friction. Self-locking nuts are categorized by function in various ways, including those with embedded nylon rings, those with neck closures, and those with metal locking devices. These nuts all fall under the effective torque type.

[0003] A nut cold heading die with application number 202223102883.6 in the prior art includes a base plate and a protective mechanism. The protective mechanism is installed at the top of the base plate and is composed of a disc seat, fastening bolts, a cold heading die body, a through slot, and a fixing bolt combination. The wall of the base plate is connected to the bottom of the disc seat by fixing bolts. The top of the disc seat is provided with a through slot for fixing the cold heading die body. The inner wall of the through slot is connected to the die wall of the cold heading die body by fastening bolts. The protective mechanism can protect the nut cold heading die and prevent the nut cold heading die from direct contact with the punch head and damage caused by long-term cold heading. However, it is inconvenient to dump and unload the nuts in the cold heading die seat, and manual unloading is time-consuming and labor-intensive. Utility Model Content
