In the world of cold forming sector of manufacturing industry, precision and efficiency are essential. Fasteners are industrial rice small but indispensable, to ensure the production of high-quality fasteners the cold heading die is critical. This article delves into the intricacies of cold heading dies, exploring their advantages, applications, and the future trends shaping this essential manufacturing tool.
1. What is a Cold Heading Die?
Definition and Function
A cold heading die is a tool used in the cold heading process to form the desired parts from metal wire without the use of heat. The dies consists of a series of precisely machined components that apply immense impact force to metal wire or rod, deforming it into specific shapes such as screws, bolts, and nuts. This process ensures high dimensional accuracy and consistency across produced parts.
Components of a Cold Heading Die
Cold heading dies are diversified by a group of components
- Wire Die: making the rough wire to be specific fine wire
- Cut-off Knife(Cutting Die): cutting-off the wire to be specific length
- First Punch with or without steel case: working together with other dies for forming the shape preliminarily
- Main Die: working together with other dies to shape the cut wire to be required size as it is pressed into the die.
- Second Punch(Header Punch): working together with other dies for forming the second or final designed size of head
- Knock-out Pins(Ejector): kicking out the formed parts form the hole of main die
- Thread Rolling Flat Die: a group of rolling tolls normally with 2 plates one shorter stationary one longer moving reciprocally working together to form the designed diversified threads
The materials used in production of cold heading dies are typically high-grade tool steels such as SKD61(H13) for the die case, Tungsten Carbide for the insert of working area, SKH9/SKH59(M2/M42) for punches, DC53/M2 for thread rolling dies, whatever materials chosen for the durability and ability to withstand repeated high-pressure operations without deformation.
2. Advantages of Using Cold Heading Dies
Precision and Consistency
One of the standout benefits of cold heading dies is their ability to produce parts with high precision and consistency. The cold heading process ensures that each fastener maintains exact dimensions, which is crucial for applications requiring tight tolerances and reliable performance.
