Copper parts and flange forming cold extrusion machine

The copper parts and flange forming cold extrusion machine developed and produced by China Jianlong Hydraulic Machinery is an efficient and precise metal forming equipment, which is specially used to make copper and copper alloys (such as brass, bronze), carbon steel or stainless steel flanges and other materials plastically deformed by high pressure at room temperature, so as to manufacture high-precision, high-strength, less cutting or no cutting parts. The following is an introduction to its core features and applications:

1. Core features

1.1 Cold extrusion process: At room temperature, ultra-high pressure (usually 500~3000 tons) is used to make the metal flow to fill the mold cavity, avoiding heating energy consumption and improving material utilization (up to more than 90%).

1.2 High rigidity structure: The closed frame or four-column design is adopted to ensure the stable operation of the equipment under high pressure and reduce the influence of elastic deformation on precision.

1.3 Precision forming: Suitable for complex geometric shapes (such as internal teeth, threads, special-shaped holes), with surface roughness up to Ra1.6 or less and dimensional tolerance ±0.03mm.

1.4 Energy saving and environmental protection: Compared with hot forging, it eliminates the heating process, has no oxide scale and smoke emission, and is in line with the trend of green manufacturing.

1.5 Automation compatibility: It can integrate feeders, manipulators and visual inspection systems to achieve fully automated production.

2. Technical advantages

2.1 Improved material performance: The cold working hardening effect improves the hardness and fatigue strength of parts (the hardness of copper parts can be increased by 20%~40%).

2.2 Cost savings: Reduce subsequent machining processes and reduce scrap rate.

2.3 Long mold life: Using tungsten steel (such as YG8) or powder metallurgy mold steel (such as ASP-23), the life can reach more than 1 million times.

3. Typical applications

3.1 Copper and copper alloy parts:

3.1.1 Electronics industry: connector terminals, conductive rings, heat sinks.

3.1.2 Plumbing industry: valve bodies, pipe joints, gears, etc.

3.2 Flange parts:

3.2.1 Pipeline system: high-pressure flange, sealing ring (carbon steel/stainless steel).

3.2.2 Automotive industry: bearing seat, differential flange, etc.

This type of equipment is particularly suitable for large-scale, high-precision parts production, and is an ideal choice for hardware, electronics, automotive and other industries.
