220 ton four column double acting stretching hydraulic press

Advantages of double-acting stretching hydraulic press
High-precision control: The servo system can precisely control the tensile force, blank holder force, slider displacement and speed. The control accuracy of tensile force can reach within ±3%, and the displacement accuracy of the slider can reach ±0.03mm, which is conducive to the production of tensile parts with high dimensional accuracy and complex shapes, meeting the strict requirements of different industries for product quality.

High efficiency and energy saving: The servo system automatically adjusts the motor speed and the output flow of the hydraulic pump according to the actual working load, avoiding the overflow loss and throttling loss of traditional hydraulic presses when they are not in operation. Compared with ordinary hydraulic presses, the energy-saving effect can reach 30% - 50%, while shortening the working cycle time and improving production efficiency.

Application field
Automotive industry: Widely used in the stretching forming of automotive body panels, such as body door panels, engine hoods, trunk LIDS, etc. It can meet the high requirements of automotive body panels for dimensional accuracy, surface quality and shape complexity, and improve the overall quality and appearance quality of the automotive body.

Home appliance industry: It is used to produce the shells of various home appliances, such as refrigerator door bodies, washing machine outer drums, air conditioner shells, etc. It can achieve high-precision stretching forming, ensuring the dimensional accuracy and appearance flatness of the shell, and enhancing the aesthetic appeal and market competitiveness of the product.
Metal products processing: In industries such as metal tableware, kitchenware, and stainless steel products, it is used to stretch metal plates into various shaped products. It is capable of producing products with regular shapes and precise dimensions, meeting consumers' requirements for the quality and appearance of metal products.
