Abstract

The invention discloses a semi-automatic isometric angle extrusion testing device, belongs to the technical field of thermal machining and extrusion of materials and can be applied to an ECAE (equal channel angular extrusion) test of a Ti5553 alloy. The semi-automatic isometric angle extrusion testing device comprises an ejection rod, a lower die, an upper die, a sample baffle device, sample ejection screws, a guide post, a sample outlet channel, a sample baffle, a baffle screw post, screw post connecting rods, an upper-die and lower-die connecting bolt and nuts. According to the semi-automatic isometric angle extrusion testing device, a #-shape channel is formed by the sample baffle device, thereby greatly facilitating the feeding of samples; as the oblique planes of sample baffles are matched with the ejection rod, the sample surrounding device can be automatically reset during extrusion; the samples can be stably taken out by the sample ejection screws without detaching the upper die and the lower die.

Description

Technical field [0001] The invention relates to a semi-automatic equal channel angular extrusion experiment device, in particular to a device suitable for titanium alloy extrusion, belonging to the technical field of material hot processing extrusion. Background technique [0002] Since its inception in the 1950s, titanium alloys have received extensive attention from the materials industry and have shown great application prospects in the fields of aerospace, military, marine, shipbuilding, biomedicine, chemical and energy. In the titanium alloy family, Ti5553 alloy has the advantages of being less sensitive to segregation, excellent strength and high fracture toughness. It is especially suitable for manufacturing parts that must withstand huge stress, such as landing gear and engine parts. It is increasingly used in the aerospace industry. Favored. [0003] Ti5553 alloy itself is relatively soft and has poor erosion and wear properties, which is an important cause of damage to p...
