Cold heading dies consist of key components: feed rollers, cutting dies, forging dies, rod dies, and ejector rods. The die head's structural design must consider material hardness, strength, and toughness to endure the intense cold heading process. The die's structure, including the head, sleeve, core, and base, critically affects the process's quality and efficiency.
This process leverages metal's plastic deformation under external force, using dies to reshape and transfer metal volume into desired parts or blanks. Ideal for manufacturing standard fasteners like bolts, screws, nuts, rivets, and pins, it often employs SKD61—a medium-carbon, high-chromium alloy tool steel known for its superior high-temperature tensile strength, heat resistance, and crack resistance.
As part of forging machinery's wire forming automatic machines, cold heading dies operate at room temperature using disc or rod materials for metal cold forming. They feature multiple stations and dies to perform concurrent cold processing steps, enhancing both efficiency and stability in production.
Cold heading dies operate by first feeding a coil of wire into a blank, which is then drawn through a wire drawing machine. This prepared blank is subsequently fed into the cold heading machine where it is struck between the die and punch. This action forces the material into the die cavity, shaping it into the required form.
The process employs various metal forming techniques, including upsetting and extrusion methods such as forward and reverse extrusion. These techniques are crucial for achieving the necessary compression and forming the metal into precise parts.
This method is particularly effective for producing components with consistent dimensions and high surface finish, making it indispensable in precision metal forming applications.
Q: How long is the sample lead time?
A: Our standard lead time is around 15 days.If the order volume is larger or require more customization,additional time might be needed.
Howerver,10 workdays is available for a small number of urgent order.
Q: What customized services do you offer?
A: Material,color,design size, shape, convex and concave marking, coating, laser engraving mark and packing are all customized.
Q: What materials are typically used for cold heading dies?
A: Cold heading dies are commonly manufactured from high-quality tool steels such as SKD61, H13, or 1.2344. These materials are chosen for their excellent combination of hardness, toughness, and wear resistance, which are essential for withstanding the demanding conditions of the cold heading process.
Q: How does the cold heading process benefit the production of fasteners?
A: The cold heading process is highly beneficial for fastener production as it allows for the creation of precise and consistent parts with high efficiency. It utilizes plastic deformation of metal under external force to form the desired shapes, which is particularly advantageous for producing standard fasteners like bolts, screws, nuts, rivets, and pins. This method ensures parts have uniform dimensions and a high-quality surface finish, contributing to the reliability and performance of the final product.
