Processing technology for high-speed abrasion-resistant metal groove drums

Abstract

The invention relates to the technical field of critical components of bobbin winders, in particular to processing technology for high-speed abrasion-resistant metal groove drums. The processing technology for groove drums includes lathing an outer circle of an inner hole; drilling a positioning pin hole; milling a yarn guiding groove; polishing the yarn guiding groove; performing surface strengthening treatment; and realizing integral dynamic balance. The processing technology is characterized in that the yarn guiding groove is milled by a numerical control machining method, a semi-finished blank of a groove drum needs to be fixedly clamped before the yarn guiding groove is machined, and then is machined, and a numerical control machining programming process for milling the yarn guiding groove includes determining milling parameters at first; setting machining coordinates; selecting tools; machining the blank; carrying out cutting simulation; determining a correct tool position track; and selecting a proper postprocessor to output a machining program after machining simulation is proved to be correct. On the basis of research of design features and structural characteristics of the groove drum, the numerical control machining method is adopted, production efficiency is improved on the premise that machining quality is guaranteed, and batch production and matching of the groove drums and the bobbin winders are realized.

Description

technical field [0001] The invention relates to the technical field of key components of an automatic winder, in particular to a high-speed wear-resistant metal groove drum processing technology. Background technique [0002] The groove drums assembled on the 1332M and 1332MD type groove drum winders that are generally used in China are bakelite groove drums that are pressed by hard bakelite. The main manufacturers of bakelite tanks in my country include Qingdao Plastic No. 6 Factory, Wuxi Bakelite Parts Factory, and manufacturers in Dandong, Shanghai and other places. Bakelite tanks are cylindrical and conical, 2-turn and 2.5-turn common phenolic plastic tanks and anti-static phenolic plastic tanks. The Bakelite drum is cheap and the process is simple, but this drum has three disadvantages: 1) The wear resistance is very poor, and the friction of the yarn on the drum can easily cause the drum to wear and fail, so the service life of this drum is longer Short, about 2-3 ye...

AI Technical Summary

Problems solved by technology

The Bakelite drum is cheap and the process is simple, but this drum has three disadvantages: 1) The wear resistance is very poor, and the friction of the yarn on the drum can easily cause the drum to wear and fail, so the service life of this drum is longer Short, about 2-3 years; 2) Power consumption is large, because this kind of tank is a solid tank and has a large mass, so the energy consumption is large when starting, which is about twice that of aluminum alloy tanks; 3) Static electricity The effect is large, and the friction transmission of the groove drum has a great influence on the hairiness. The bakelite groove drum is prone to generate static electricity during the winding process, causing yarn fluffing, pilling, and breakage, which is not conducive to improving the quality of the yarn, especially in the winding of ramie yarn. When the high-speed rotary drum rubs against the yarn, strong static electricity is generated and is not easy to dissipate. When the static electricity on the drum is accumulated to a certain extent, it will interfere with the normal movement of the yarn, resulting in an increase in hairiness. The bobbin is poorly formed, and it will cause static electricity to catch fire in severe cases

[0004] At present, the high-speed wear-resistant metal groove drum is mainly monopolized by companies such as Japan MURATA, Japan MINO, Italy savio, Germany schlafhorst and other companies, and there are no mature products in China that are matched with automatic winders in batches.
