Abstract

The invention belongs to the technical field of surgical knife machining die jigs, and particularly relates to a surgical knife handle welding clamp. According to the surgical knife handle welding clamp, rare earth elements are added, high-content Mg is adopted, a trace amount of Ti is added for refining the structure, and the mechanical performance of an alloy is improved. Cu can be used for forming a strengthening phase CuAl2 and can also be used for forming a high-temperature strengthening phase CuMgAl2 with Mg, and tenacity of the alloy is improved; the quenching sensitivity of the alloy can be improved through Zr, Mn and Cr, a fiber structure in the alloy can be maintained at a very high level through Mn and Zr, particles can be refined through Cr, and the fiber structure is retained; Mg2Si particles and grains can be refined through Cu and Fe, and Si atoms leave the grain boundary; atomic energy of lanthanide loses valence electrons, and a +3 valent stable compound can be formed; and through combination of Nd and Y, the temperature resistance is improved to a greater degree, and meanwhile plasticity and tenacity can be improved through Y.

Description

technical field [0001] The invention belongs to the technical field of mold fixtures for processing scalpels, and in particular relates to a welding fixture for a scalpel handle. Background technique [0002] A medical scalpel is a medical instrument used for cutting, often called a lancet, which is divided into a handle, a knife rod and a knife head, wherein one end of the knife rod is fixed in the installation groove of the knife handle, and the other end is connected to the knife head Solder connected. During processing, processing personnel are required to weld the scalpel one by one, which has low work efficiency and high labor intensity; and with the rapid development of medical devices, the requirements for the structure and performance of welding fixtures are getting higher and higher, and reasonable welding fixtures are beneficial Improves scalpel welding performance. Contents of the invention [0003] Purpose of the invention: In order to overcome the above pro...
