Cold extruder for machining sprayer shaft and machining process of sprayer shaft

Abstract

The invention discloses a cold extruder for machining a sprayer shaft. The cold extruder comprises an upper extrusion part, an extrusion table, a demolding part, a PLC control system, a hydraulic system and a guide support column; the upper extrusion part is supported by the guide support column; the upper extrusion part and the demolding part are driven by the hydraulic system to perform an extrusion motion along the guide support column; and the PLC control system controls the hydraulic system to work. The cold extruder is characterized in that the upper extrusion part includes an upper pressing head and an upper mold; the upper mold and the upper pressing head are detachably connected; a detachable lower mold is arranged on the extrusion table; a hole is formed in the bottom of the lower mold; the demolding part is provided with a hydraulic cylinder and a demolding rod driven by the hydraulic cylinder; and the demolding rod is positioned rightly below the hole of the lower mold. The cold extruder solves the problems of low machining efficiency and high machining cost in large-batch machining of shafts used by atomizing agents in the prior art.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a cold extrusion machine for processing a sprayer shaft and a processing technology for the sprayer shaft. Background technique [0002] attached figure 1 The middle is a typical structural diagram of the sprayer shaft. The diameter of the sprayer shaft decreases stepwise from the middle to both ends, the shoulder between the large diameter shaft and the small diameter shaft is excessive, and there are splines on the sprayer shaft Or gear structure, it is very difficult to adopt conventional processing methods, and the labor cost is very high. [0003] Usually the processing method of the shaft is turning. If you choose CNC lathe for processing, although the processing quality of CNC lathe is good, but the processing cost is high. For a shaft workpiece, it needs to be processed many times, and the amount of each turning is very limited. Later processing Splines are furth...
