The above-mentioned presses have well fulfilled the requirements for pressure processing of materials in the general industrial field, but for some special pressure processing, such as the pressure processing of extra-large-scale metal parts (head processing with a scale of tens of meters) is more difficult. The main problem is that there is no such a large ready-made hydraulic press in modern industry. Even if the construction of such a press is theoretically established and technically feasible, it is not feasible in terms of processing cost for the extremely large pressure processed parts that require a very limited number. It is necessary to manufacture a hydraulic press with such a huge scale; in addition, the energy for pressure processing in the current industrial presses comes from the prime mover, and the submersible static pressure differential hydraulic press proposed in this patent is reasonable for seawater static pressure. The use of seawater static pressure difference to realize the pressure processing method of materials also has the characteristics of using new marine energy and energy saving compared with traditional presses.

The invention relates to a diving static pressure difference raised mould type press machine. A material forming processing device for utilizing seawater static pressure to pressurize a material is simple in structure, is low in cost, requires no power source and can directly utilize the seawater pressure to perform processing. According to the invention, a driving device capable of utilizing the static pressure difference between seawater pressure and a low-pressure gas cylinder as executing element power source to process the material in the bottom of the sea can be used for processing an ultra-large workpiece. Compared with the present press machine, the diving static pressure difference raised mould type press machine has the advantages that the structure is simple, no external power source is required, and the size of the processed workpiece is not limited.
Description
technical field [0001] The invention relates to the field of marine engineering machinery processing and manufacturing, in particular to a submersible static pressure differential convex mode press. Background technique [0002] The 21st century is called the Ocean Century, and people are developing and utilizing marine resources more and more deeply. In the vast ocean, the deepest seawater can reach tens of thousands of meters, and the hydrostatic pressure corresponding to the water depth can reach thousands of engineering atmospheric pressures. Reasonable use of the static pressure generated by the vast ocean and water depth to realize material pressure processing is different from traditional methods. The obvious new technical characteristics of the surface atmosphere environment. [0003] The press is an important equipment for pressure processing such as material forming, and plays an important role in the processing of industrial products. The traditional presses mai...
