Ultra-high pressure wire winding hydraulic press: the core power of precision extrusion and high-end forging

Recently, a 2,000-ton ultra-high-pressure steel wire winding servo precision extrusion integrated forming hydraulic press from Zhongshan Wanda Machinery was successfully loaded and shipped to the customer"s production line. This equipment is specially designed for one-time precision extrusion molding of base material shells such as pure aluminum and oxygen-free copper. With its high-strength body and servo precision pressure control system, it can stably achieve the integrated forming of the inner and outer walls of high-depth shells. Its smooth delivery not only marks another success for Wanda Machinery in the field of precision extrusion molding equipment, but also reflects the market"s urgent demand for high-quality, high-efficiency molding equipment.

In the field of precision extrusion molding, the core competitiveness of equipment lies in "stability" and "precision". The ultra-high-pressure steel wire winding technology used in the 2,000-ton hydraulic press is an important technological breakthrough in the field of heavy-duty hydraulic presses in recent years. This technology applies pre-tightening force to the frame by winding prestressed steel wires, which greatly improves the rigidity and fatigue strength of the frame, while effectively reducing the weight and volume of the equipment. With the servo precision control system, the equipment can accurately control pressure and displacement, and the no-load repeated displacement accuracy can reach ±0.02mm. It is this combination of high rigidity and high precision that allows deep-cavity shells made of pure aluminum, oxygen-free copper and other materials to be integrally formed with the inner and outer walls in one extrusion. The material utilization rate is high and the amount of subsequent processing is small, which provides a solid guarantee for the efficient mass production of shell parts.

If the 2,000-ton extrusion press is a powerful tool for precision forming, then the 8,000-ton ultra-high-pressure steel wire winding servo precision CNC forging hydraulic press is the key to determining the quality of motorcycle wheels. The quality gap between motorcycle wheels ultimately stems from the gap in forging strength. Ordinary cast wheels inevitably have defects such as pores and looseness inside, but forged wheels use a 10,000-ton hydraulic press to exert huge pressure on the solid aluminum billet, so that the metal grain structure is arranged in a continuous fiber shape, and the density is greatly increased. Test data shows that the strength of forged wheels under the same size is more than 30% higher than that of cast products, while the weight can be reduced by about 20%. Wanda Machinery"s 8,000-ton forging hydraulic press is deeply involved in the field of automobile and motorcycle parts forging, and the high-pressure forging conditions are stable and reliable. The equipment uses 6061 or 7075 aviation-grade aluminum alloy billets, which are repeatedly forged and formed under 8,000-ton pressure. The finished wheel hub is stronger and lighter in weight, conquering the core link of high-end forged wheel hub production in one fell swoop.

In fact, Wanda Machinery has built a series of ultra-high-pressure steel wire winding servo precision CNC hot and cold forging hydraulic presses covering 2000T, 3500T, 8000T and even larger tonnage. These equipment are widely used in precision cold forging, hot forging and extrusion forming processes of various round bars and plates such as stainless steel, IGBT copper base, aluminum alloy, ordinary carbon steel and so on. From military industry, aerospace to new energy, photovoltaics, and automobile and motorcycle parts, Wanda Machinery"s equipment has covered many key industries.

The company"s R&D and production capacity has reached 60,000T, and it has more than 60 invention patents, utility models, and software copyrights. It has participated in the drafting and formulation of 3 national standards and 8 mechanical industry standards. Currently, the order schedule for the wire winding hydraulic press series is tight and the production cycle is long. For customers who intend to deploy similar shell production lines and high-end forging production lines, it is imperative to negotiate orders in advance and seize market opportunities. Industrial forging, premium equipment; customization on demand, strong supply - Wanda Machinery is using its hard-core technical strength to help China"s manufacturing move to a higher level.
