külmetusekstrusioonitööriistad

Külmetusekstrusioonitööriistad refer to specialized tooling used in cold extrusion processes. Cold extrusion is a metal forming process where metal is forced through a die at or near room temperature. This method is used to produce a variety of parts, often with complex shapes and tight tolerances, and without significant heating of the workpiece.

The tools involved in cold extrusion must withstand very high pressures and stresses. They are typically made from hardened and tempered tool steels or other high-strength alloys to ensure durability and prevent deformation or failure during the extrusion cycle. The design of these tools is critical to achieving the desired part geometry and surface finish.

Key components of külmetusekstrusioonitööriistad include the die, which shapes the workpiece, and the punch or ram, which applies the force. The die often has a specific profile that the material flows through, reducing its cross-sectional area and increasing its length. The punch is responsible for pushing the material into or through the die cavity. Lubrication is also an essential consideration in cold extrusion tooling to reduce friction and wear between the tool and the workpiece. Specialized lubricants are applied to the workpiece and sometimes to the tooling itself.

The manufacturing of these tools requires precise machining and finishing techniques to achieve the required accuracy and surface quality. Surface treatments like nitriding or coating can also be applied to enhance wear resistance and extend tool life. The selection and maintenance of külmetusekstrusioonitööriistad are crucial for efficient and high-quality production in cold extrusion applications.
