Cold heading processing
Cold heading is a part processing method that utilizes the plasticity of metal at room temperature and uses a cold heading machine mold to exert a certain pressure on the metal blank to cause the metal blank to plastically deform in the mold cavity to obtain the required shape, size and performance. It is a low-cutting processing technology that can effectively improve material utilization. Efficiency
Cold heading processing itself is an efficient forming process. Compared with traditional machining, cold heading can produce parts with similar shapes in large quantities in a short time. For example, a cold heading machine can produce dozens to hundreds of parts per minute, and the subsequent finishing process can also achieve higher production efficiency through automated equipment during mass production.
High material utilization rate
Since cold heading forms parts through plastic deformation of metal, material loss is mainly during the blank blanking stage and a small amount of subsequent processing allowance. Compared with cutting processing, cold heading can greatly reduce material waste. For example, when manufacturing a complex-shaped cold-headed non-standard part, the material utilization rate can reach more than 80%, while the cutting process may only be 40% - 60%.
Precision controllability
After cold heading, the parts already have preliminary shape accuracy. Through the finishing process, the accuracy of the parts can be controlled to a very high level. For example, using a CNC grinder to grind cold-forged shaft parts can control the cylindricity within ±0.002mm to meet the assembly requirements of high-precision equipment.
(1) Automobile industry
engine parts
There are a large number of hardware cold heading non-standard parts in automobile engines. For example, the specially shaped piston pin is a key component connecting the piston and the connecting rod and needs to withstand high-frequency reciprocating motion and large impact loads. Cold heading processing can make the piston pin have good strength and toughness. After finishing, it can ensure its dimensional accuracy, ensure the precise fit between the piston and the connecting rod, and reduce the vibration and wear of the engine.
Chassis components
There are some non-standard shaped connecting bolts and nuts in the suspension system of the car chassis. These components need to have high strength and fatigue resistance to ensure the safety and comfort of the car while driving. The cold-forged chassis hardware can meet these requirements through appropriate heat treatment and finishing, and non-standard parts can be designed and produced according to the chassis structure of different car models.
Interior parts
Some decorative hardware in automobile interiors, such as specially shaped knobs, handles, etc., are also cold-headed non-standard parts. These components must have a certain degree of strength and durability while ensuring a beautiful appearance. Through cold heading and finishing, various hardware components can be manufactured to match the design style of automobile interiors.
(2) Electronic equipment
mobile phone parts
There are many tiny cold-forged non-standard hardware parts inside the mobile phone. For example, the head shape and size of the tiny screws used to fix the circuit board need to be designed according to the internal space and assembly requirements of the mobile phone. After these screws are formed by cold heading, they undergo precision finishing, such as surface treatment to prevent oxidation, ensuring that they will not loosen during long-term use and ensure the normal operation of the mobile phone.
computer parts
Cold heading non-standard parts are also used in computer hard drives, radiators and other components. For example, some high-precision shaft parts in hard disk drives can ensure their roundness and cylindricity through cold heading and finishing, so that the read-write head of the hard disk can accurately work on the disk, improving the efficiency of data storage and reading. reliability.
(3) Machinery manufacturing
Machine tool components
There are many key hardware cold heading non-standard parts in machine tools. For example, the screw rod of a machine tool is processed into a preliminary shape through cold heading, and then undergoes high-precision grinding and other finishing processes to make it highly precise. The accuracy of the screw directly affects the processing accuracy of the machine tool. Through cold heading and finishing, screws that meet the requirements of machine tools of different accuracy levels can be manufactured.
Automation equipment components
On the manipulator of the automated production line, there are some special-shaped connectors and joint parts that are cold-forged non-standard parts. These parts need to have good flexibility and strength. Through cold heading and finishing, high-precision hardware that meets the movement requirements of automated equipment can be manufactured to ensure the precise operation of the robot.
