Abstract

A titanium thin plate vacuum hot-press orthopedic process, including a titanium thin plate swing process and a vacuum hot-press orthopedic process, the swing process includes: step 1, placing a tray on the tray bracket in the vacuum hot-press orthopedic furnace, and placing the tray on the tray Place the bottom plate, the bottom plate is covered with lining plates, and there are gaps between the lining plates; step 2, stack the titanium thin plates up and down on the lining plate, and a partition is provided between the upper and lower stacks of titanium thin plates, and the partitions are respectively and Place the liner between the upper and lower titanium sheets according to the method of step 1 to obtain the stack of titanium sheets; step 3, place the liner on the top of the titanium sheet stack according to the method of step 1, and place the pressing plate on the lining plate, the pressing plate Place briquettes on the top, leaving gaps between briquettes; step 4, arrange the cleaned and fully dried titanium chips around the stack of titanium sheets, and fix them with metal mesh to complete the placement process. The invention can realize high flatness and surface quality of the titanium thin plate, low-cost vacuum hot-pressing correction, and simultaneously solve the problems of surface oxidation and pollution.

Description

technical field [0001] The invention belongs to the field of non-ferrous metal processing, and in particular relates to a titanium thin plate vacuum hot-pressing orthopedic process. Background technique [0002] Titanium has the advantages of light weight, high strength, corrosion resistance, and non-magnetic properties. It is widely used in aerospace, marine, electronics, medical and other fields. Among them, titanium and titanium alloy sheets with a thickness of 0.1~3mm are the most widely used. With the development of technology, customers have higher and higher requirements for the flatness and surface quality of titanium and titanium alloy sheets. In the production process of titanium thin plate, it has to go through multiple processes such as hot rolling, cold rolling, heat treatment, and slitting. Titanium thin plate has different degrees of curvature and needs orthopedic treatment. However, due to the low elastic modulus, high resilience and high strength of titaniu...
