Crimping Head Assembly for Automated Wire Harness Crimping Machines

Product Specifications

Technical details and manufacturing context for Crimping Head Assembly

Definition

The Crimping Head Assembly is a precision mechanical component within an Automated Wire Harness Crimping Machine. It is responsible for the critical task of applying controlled force to deform a metal terminal or connector around a stripped wire end, creating a secure, gas-tight, and electrically conductive connection. This assembly directly interfaces with the machine's feed system and control unit to execute the crimping cycle. The assembly typically consists of a frame, a ram or punch, a die set, and an actuation mechanism (hydraulic, pneumatic, or servo-electric). It is designed to accommodate various terminal sizes and wire gauges, with adjustable crimping height and force settings. The materials used, such as tool steel, carbide, and high-strength alloy steel, ensure durability and wear resistance. Key parameters include a crimping force range of 20–50 kN, a crimping height adjustment range of 0.5–3.0 mm, and a crimping precision of ±0.02 mm. The cycle rate can reach 60–120 cycles per minute, depending on the model. Operating pressure is specified as 0.5–0.8 MPa, and the operating temperature range is 5–50 °C. The assembly has an ingress protection rating of IP54–IP65 (IEC 60529) and is compatible with DIN 48083 die sets. The weight ranges from 8–15 kg. These values are reference ranges and must be verified for the specific model and application with the legal manufacturer or supplier. The assembly's performance directly affects the quality of the crimped connection, making proper selection, installation, and maintenance critical.

Working Principle

The assembly receives a terminal from the feed system and positions a stripped wire within it. A hydraulic, pneumatic, or servo-electric actuator drives a ram or punch, which forces the terminal's crimp wings into a precision die. This plastic deformation of the terminal material around the wire strands creates a permanent mechanical and electrical bond. The assembly then releases the finished crimp.

Frequently Asked Questions

What is the typical crimping force range for this assembly?

The reference range is 20–50 kN. However, the exact force required depends on the terminal size and wire gauge. Always verify the specific model's capabilities with the manufacturer.

Can the crimping height be adjusted?

Yes, the crimping height adjustment range is 0.5–3.0 mm, allowing accommodation of different terminal sizes. Adjustments should be made according to the manufacturer's instructions.

What is the operating temperature range?

The specified operating temperature range is 5–50 °C. Operating outside this range may degrade seals and lubricants, affecting performance.

Is the assembly compatible with standard dies?

The assembly is designed for compatibility with DIN 48083 die sets. However, always confirm compatibility with the specific die set and model before use.
