Non-ferrous metal science and technology research and development testing center is a comprehensive research institution focusing on the research, development, trial production and industrialization of new materials, new products, new processes, new technologies and new equipment of non-ferrous metals and their alloys. It aims to fully implement research and technological innovation in the field of non-ferrous metal industry, undertake daily tests of enterprises, and conduct process tests and new product development in aluminum processing. It is planned to cooperate with famous universities and scientific research institutions at home and abroad, take the road of scientific and technological innovation combined with Industry-University-Research, and carry out research and development in the frontier field of non-ferrous metal processing, so as to make it the most influential scientific research and testing institution in northwest China. R&D center consists of two parts: test room and test workshop.
The laboratory selects 35 sets of various testing instruments, including universal tensile testing machine, fracture toughness testing machine, fatigue testing machine and corrosion testing machine; The photoelectric direct reading spectrometer, X-ray fluorescence spectrometer, atomic absorption spectrometer, carbon-sulfur analyzer, oxygen-nitrogen-hydrogen analyzer, plasma emission spectrometer, electron probe, scanning electron microscope, transmission electron microscope, X-ray diffractometer, metallographic microscope and high temperature metallographic microscope will be introduced.
The test workshop selected melting and casting units, double-acting forward and backward extruders, heating furnaces, aging furnaces, surface treatment equipment, machining equipment and other equipment. And there are all kinds of oil, water and production accessories testing equipment. The task of this center is to produce dies, needles, extrusion pads and modules needed for forging 5 ~ 5~ 160MN aluminum and aluminum alloy extruder, and also undertake the equipment maintenance task of this enterprise. The design scale is 8000 sets/year (about 10400T).
The tool and mold manufacturing center consists of a hot working workshop and a cold working workshop. This design is a cold working workshop, that is, a mold workshop. Reserve the land for the mold hot processing workshop.
The main production equipment in the mold workshop includes mechanical processing equipment, electrical processing equipment, heat treatment equipment and riveting and welding equipment. In order to complete the production task and ensure the machining quality of the mold, the workshop chose the machining center, so that various processes can be completed on the same machine tool to ensure the pass accuracy; The key parts of the mold, such as the working area of the mold, are machined by EDM and CNC wire cutting machine. In order to improve the smoothness of the die hole, an extrusion honing machine is used.
