Description

technical field [0001] The invention relates to a metal plastic extrusion forming equipment, in particular to a main machine of the metal plastic extrusion forming equipment. Background technique [0002] Metal extrusion technology is a processing technology with less and no cutting pressure. It is an important branch of forging processing technology and an important part of advanced manufacturing technology. Compared with traditional manufacturing technology, it has the advantages of saving materials and energy, reducing processing procedures and equipment, improving production efficiency and product quality, and reducing production costs. However, due to the limitation of current equipment (mainly friction presses, mechanical presses, flat forging machines, etc., which cannot process parts with large deformation due to their low energy supply) and mold materials, this technology cannot be used. widely used. [0003] At present, there are many technical bottlenecks in the...

AI Technical Summary

Problems solved by technology

However, due to the limitation of current equipment (mainly friction presses, mechanical presses, flat forging machines, etc., which cannot process parts with large deformation due to their low energy supply) and mold materials, this technology cannot be used. widely used

[0003] At present, there are many technical bottlenecks in the application of precision forging technology and extrusion molding equipment at home and abroad, so that the technology cannot be fully developed

[0004] First, the energy supply is not large enough to meet the energy demand for the deformation of complex parts. Although the force (tonnage) of a single device is sufficient, the energy supplied is not enough, and multiple extrusions of multiple devices are required to meet the requirements. The geometric deformation of parts will inevitably lead to large investment in equipment and waste of resources, which will affect the widespread promotion and application of this technology. Therefore, general industrial and mining enterprises dare not enter

[0005] Second, the mold has no versatility and interchangeability, resulting in a product specification requiring a pair of molds, so that the equipment is only suitable for batch production, and the applicable area is narrow

[0006] Third, the extrusion processing production line is long, requiring multiple sets of equipment and 5 to 20 production workers, the production site is large, the working environment is harsh, and the production cost is high
