A horizontal fully automatic equal-diameter angular extrusion experimental device

Abstract

The invention provides a horizontal type full-automatic equal channel angular extrusion experiment device. The horizontal type full-automatic equal channel angular extrusion experiment device comprises an ejection rod, an upper die, a lower die, a separation device, a pushing-out device, a filling device, a rear cover, rear cover lower die connection bolts, upper and lower die connection bolts and nuts, a sample storing through hole of the upper die, a separation rod through hole, a pushing-out rod through hole, upper membrane countersinks, a through hole a, pushing-out push block lug bosses, a separation push block groove, a spring hole a of the lower die, a rear cover thread hole, shaft grooves, lower membrane countersinks, stud holes, an equal channel angular channel, a pushing-out push block groove, a filling support groove, a filling slide block groove and an extrusion channel. The horizontal type full-automatic equal channel angular extrusion experiment device has the advantages that the disadvantages of an existing ECAE experiment device or die are overcome, the impact on a sample de-molding process is small, and the integrality of a sample is guaranteed.

Description

technical field [0001] The invention relates to the technical field of thermal processing and extrusion of materials and the field of material experiment research, and is a horizontal fully automatic equal-diameter angular extrusion experiment device. [0002] technical background [0003] Titanium alloy has the advantages of high specific strength and strong corrosion resistance. Since its appearance in the 1950s, it has been widely used in many fields such as aerospace, military, ocean, ship, biomedicine, chemical industry and energy, and has become a new type with strong vitality. Key structural materials have very important application value and broad application prospects. The near-β-type Ti-5553 alloy is a new type of titanium alloy with high strength and high fracture toughness developed from the Russian alloy BT22F. Compared with Ti-1023 alloy, this alloy does not produce obvious compositional segregation, has the advantages of excellent strength and high fracture st...

AI Technical Summary

Problems solved by technology

However, the existing ECAE experimental devices or molds at home and abroad have the following disadvantages: (1) The rigidity and instability resistance of the ejector pin are not ideal, which may easily lead to unsuccessful extrusion; (2) It will cost a certain amount of time to load the sample and the ejector pin into the mold. (3) It is difficult to remove the sample from the mold, and it is necessary to disassemble the experimental device or mold, or knock the sample to take out the sample, which is easy to cause the sample Deformation, inconvenient for experimental research, and adverse effects on experimental results; (4) The degree of automation is low, requiring manual operation and control, and there are certain requirements for the technical level of experimenters, and experimental failures may occur due to improper operation

[0007] In summary, the existing ECAE experimental devices or dies cannot efficiently meet the experimental research on Ti5553 alloy extrusion.
