Installation method of automatic equal diameter angle extrusion equipment

Abstract

The invention relates to a full-automatic equal channel angular extruding equipment mounting method. The full-automatic equal channel angular extruding equipment mounting method comprises an ejector rod, an upper mold, a lower mold, a separating device, a pushing-off device, a filling device, a rear cover, a rear cover and lower mold connecting bolt, a bolt and a nut for connecting the upper mold and the lower mold, a sample placement through hole of the upper mold, a separating rod through hole, a pushing rod through hole, an upper membrane counter bore, a through hole a, a pushing block pushing-out boss, a pushing block separating groove, a spring hole a of the lower mold, a rear cover threaded hole, an axial groove, a lower membrane sink hole, a stud hole, an equal channel angular channel, a pushing block pushing-out groove, a filling support groove, a filling sliding block groove, and an extruding channel. The full-automatic equal channel angular extruding equipment mounting method has the advantage of overcoming the disadvantages of the existing ECAE (Equal Channel Angular Extrusion) experimental facility or the mold, the impact force is low in a sample demolding process, and the integrity of a sample is ensured.

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, is a fully automatic equal-diameter angular extrusion equipment installation method, and belongs to the field of machinery. Background technique [0002] 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. The key structural material has very important application value and broad application prospects; the near-β-type Ti-5553 alloy is a new type of high-strength and high-fracture-toughness titanium alloy developed from the Russian alloy BT22F; compared with Ti-1023 alloy , the alloy will not produce obvious compositional segregation, has the advantages of excellent stren...

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 the experimenters. Experimental failures may occur due to improper operation, and installation The method is also very particular, once the installation is wrong, it will be scrapped directly

[0006] In summary, the existing ECAE experimental devices or molds cannot efficiently meet the experimental research on Ti5553 alloy extrusion, and the installation method of the existing equipment is very critical, which is directly related to the quality of the final product
