Sheet metal stretching machine

Description

400 tons tensile machine” usually refers to the nominal tensile force (maximum output force) of 400 tons of tensile equipment, mainly used for metal materials, plastics, rubber, composites, etc. for tensile loading, molding, processing or performance testing.or performance testing.Its core function is to produce plastic deformation or fracture of materials by applying controlled tensile force, which is widely used in industrial manufacturing, scientific research and testing.

Three beams and four columns design
Adopting steel plate welding frame, three beams (upper beam, slider, table) and four columns form a stable frame to ensure high rigidity and strong anti-deviation load capacity, suitable for long time high load transportation.
Hydraulic system configuration
Equipped with high-pressure hydraulic pump, hydraulic cylinder and control system, the piston movement is driven by hydraulic oil pressure to realize the precise stretching of metal plates.
The system pressure is usually 25MPa, and the effective stroke of the slider can reach 600mm, with an opening height of 1000mm, which can meet the processing requirements of different thickness of plates.
Automation and Intelligent Control
Integrated PLC programmable controller supports manual/automatic dual mode operation, adjustable working pressure, pressing speed and stroke range.
Some models are equipped with servo numerical control system, which realizes precise control of speed and stroke, and improves production efficiency.

Typical Application Scenarios
Automobile Manufacturing
Engine parts: stretch molding cylinder block, cylinder head, piston and other key parts to ensure sealing and high temperature resistance.
Transmission system: produce gearbox shells, transmission shafts, etc., and ensure the coaxiality of the parts through precise stretching.
Body structure parts: manufacture curved parts such as doors, roofs, etc. to enhance the strength and safety of the body.
Aerospace field
It is used for the stretch molding of large-scale integral wall plates, skins and other parts to meet the requirements of lightweight and high strength.
For example, the quenching and stretching process for 50-180mm thick plates relies on 400-ton equipment for residual stress relief.
Home Appliances and Kitchenware Industry
Stainless steel water tanks, sinks, washbasins and other deep-drawing products, through the 400-ton stretching machine to achieve a one-time molding, reducing the welding process
