Abstract

The invention discloses an oxide shell treatment device for a reverse extrusion machine, and relates to the field of machining. The oxide shell treatment device comprises a cleaning shaft and a cleaning ring, wherein a screw rod is arranged on the end part of the cleaning shaft, one end of the screw rod is fixed to the tail part of the cleaning shaft through an anti-rotation mechanism, and the screw rod and the cleaning shaft are coaxial; a press ring is arranged at the other end of the screw rod, the cleaning ring is arranged on the outer wall of the press ring, a location key axially extending is arranged between the press ring and the cleaning ring, and an annular projected step is arranged at the front end of the press ring; a gap is formed in the cleaning ring; and a fixed sleeve is arranged outside the cleaning shaft, the cleaning shaft is slidably connected in the fixed sleeve, a guide groove penetrating through the gap in the cleaning ring and forming smooth transition is formed in the periphery of the cleaning shaft, a notch penetrating through the gap is formed in the annular step, a scraping block is arranged at the inner side of the fixed sleeve, and one end of the scraping block is embedded into the guide groove. The device timely cleans up oxide shells accumulated in the gap, so that the cleaning ring normally shrinks and deforms in an extrusion barrel.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to an oxidation shell treatment device for a reverse extruder. Background technique [0002] In the production process of the reverse copper extrusion machine, after each extrusion, a tubular cast copper oxide peeling shell will be produced on the inner wall of the extrusion cylinder. Before the next extrusion, this layer of oxide shell must be cleaned, otherwise it will It will affect the quality of subsequent extrusion products. In the traditional oxide shell cleaning device, one is to fix a rigid cleaning pad on the cleaning shaft for cleaning. This structure has extremely high requirements on the coaxiality between the extrusion cylinder and the cleaning shaft, and its installation is very difficult, and after many times of use, due to wear and tear, the cleaning pad cannot completely clean the oxide shell in the extrusion cylinder, resulting in Product defects. And this ...
