Làm thế nào để keensert thực hiện chức năng sửa chữa chủ đề?

Keensert is a type of threaded insert, commonly known as a key-locking insert or a helical insert. Threaded inserts like Keenserts are used to repair damaged threads or provide stronger threads in materials with low strength, such as aluminum or magnesium. Here’s how a Keensert performs a thread repair function:

1. Design: Keenserts have a unique design featuring external threads and a series of keys or tangs along the length of the insert. These keys are slotted or notched metal strips that are coiled into the insert during manufacturing.

2. Cài đặt: To install a Keensert, a pre-wound insert is threaded into a tapped hole that matches its external threads. The insert is then expanded using a special installation tool. As the insert is expanded, the keys or tangs are forced into the tapped threads in the hole’s wall.

3. Locking Mechanism: Once fully installed, the keys or tangs embed themselves into the parent material, creating a mechanical lock that prevents the insert from rotating or backing out. This locking mechanism enhances the stability and strength of the threaded connection.

4. Thread Reinforcement: The helical design of the insert provides a new set of internal threads, often with a larger diameter than the original damaged threads. This not only repairs the damaged threads but also reinforces the connection, often providing better strength and load-carrying capacity than the original threads.

5. Material Compatibility: Keenserts can be used in a variety of materials, including metals, plastics, and composites. This makes them versatile for a range of applications where thread repair or reinforcement is necessary.

6. Applications: Keenserts are commonly used in aerospace, ô tô, and other industries where threaded connections are critical. They are particularly useful in situations where the parent material is softer or weaker, as they provide a stronger and more durable threaded connection.

Keenserts perform a thread repair function by embedding keys or tangs into the existing threads of a tapped hole, creating a secure and mechanically locked connection. They also provide new, reinforced threads for improved strength and durability.
