Mine hydraulic fittings jacket and ball core cold extrusion process

Mine hydraulic fittings mainly used for mine , tamping tract and other hydraulic systems . Due to security needs to be updated quickly , demand, be manufactured by machining , process is relatively simple, but relatively large pore size coat , causing supplies more traditional production process , and the production is low , it is necessary to change the conventional pipe joint mine production methods. Cold extrusion process with supplies ,  Hydraulic hose fittings high efficiency advantages. As a superior performance with little or no machining processes, both technically and economically practical value . In machinery, instrumentation , electrical appliances, light industry, aerospace, marine, military, and other industrial sectors has been widely used . With China's metal cold extrusion techniques and die industry, has been able to produce high- precision cold extrusion dies and equipment . Northwest Rubber plant commissioned by the C-13 core and jacket pipe joints were studied an extrusion extrusion extrusion process analysis and process analysis extrusion Figure 1.1 shown in Figure 1 , (a) for the tube connector Jacket (C-13) of the parts diagram , (b) φ9 mm inner diameter core tube fitting (JWT-13 × 2) part drawings . Technical requirements: heat 180HB ~ 210HB, surface passivation treatment , coating thickness of 0.008 mm ~ 0.015 mm.
