Cold extrusion hydraulic press

Cold extrusion hydraulic press is a hydraulically driven pressure equipment specially used for cold extrusion process. It has the characteristics of high pressure, high precision and strong controllability, and is suitable for cold plastic forming of metal parts. After years of research and development and production, Jianlong Hydraulic Technology has accumulated a large number of cold extrusion application technologies, applied to the field of hydraulic machinery, and served a large number of customers. It is also committed to working with different customers to promote the progress of technology and the improvement of quality and efficiency in the hydraulic press industry. The following is a brief introduction to the cold extrusion hydraulic press we have compiled for your reference when selecting a hydraulic press.

1. Equipment features

1.1 High pressure: Cold extrusion requires a huge deformation force (usually hundreds to thousands of tons), and the hydraulic press can stably output high pressure through the booster system.

1.2 Controllable speed: The working speed is adjustable (slow extrusion ensures that the material fully fills the mold, and fast return improves efficiency).

1.3 Accurate stroke: Use servo hydraulic or CNC system to control the stroke accuracy of the slider (±0.01mm level).

1.4 Rigid structure: frame or four-column machine body, strong anti-eccentric load capacity, ensuring mold centering.

2. Equipment classification and selection

2.1 According to structure:

2.1.1 Four-column: strong versatility, suitable for small and medium-sized parts (such as fasteners).

2.1.2 Frame: higher rigidity, suitable for large or asymmetric parts (such as automobile shafts).

2.1.3 Horizontal: used for lateral extrusion of long rod parts.

2.2 According to function:

2.2.1 Single-acting hydraulic press: basic extrusion function.

2.2.2 Double-acting hydraulic press: with inner and outer slides, suitable for composite extrusion (such as cup-rod composite parts).

3. Typical processes:

3.1 Forward extrusion/reverse extrusion: such as automobile piston pins and shell products.

3.2 Precision cold forging: such as gears and bearing rings.

3.3 Punching and extrusion composite: such as shaft parts with flanges.

4. Typical application areas

4.1 Automotive industry: piston pins, wheel hub bolts, transmission shaft parts.

4.2 Electronics and electrical appliances: terminal blocks, capacitor housings.

4.3 Military and aerospace: shells, rocket engine parts.

4.5 Daily hardware: screws, nuts, knives.
