Embodiment Construction

[0016] figure 1 Shown is a structure of an expanding ring-type fixed extrusion pad for an aluminum extrusion machine. The expansion ring type fixed extrusion pad includes a connecting body 2, a bolt 3, a ring pad 4, a spring 5, an expanding ring 6 and a cone pad 7 which are threaded on the extrusion rod 1; There is a spring inside, and the bolt connects the extrusion pad connecting body with the cone pad. The expansion ring is installed outside the extrusion pad connecting body. The inner cone surface of the expansion ring matches the cone surface of the cone pad, and the tail of the expansion ring matches the connecting body. ; The expansion ring is separated from the connecting body; the ring pad is installed between the extrusion rod and the expansion ring. The matching part between the middle hole of the connecting body and the cone pad is provided with a key 8 to prevent the rotation of the cone, and the key is fixed on the cone pad by a screw 9. Mounting holes 10 are s...

Abstract

A fixed expanding-ring pressing block for the squeezer of aluminium part is composed of main body with spring in its central hole, conic pad, screw bolt for connecting said conic pad with main body, expanding ring with front and back conic surface for maching with said conic pad, pressing rod, ring pad between pressing rod and expanding ring, etc.

Description

technical field [0001] The invention belongs to the field of extrusion processing of aluminum and aluminum alloys, and in particular relates to an expanding ring type fixed extrusion pad for an aluminum profile extruder. Background technique [0002] The extrusion gasket is one of the extremely important extrusion tools in the extrusion machine. When extruding, an extrusion gasket is set between the extrusion rod and the billet aluminum ingot to transmit the extrusion force and seal the extrusion cylinder, so as to avoid the reduction of strength due to the direct contact between the extrusion rod and the high-temperature billet, Prevent the entire extruded rod from being scrapped due to excessive wear and deformation caused by the direct fit between the extruded rod end and the extruded cylinder. In a traditional extrusion machine, generally 2 to 3 movable extrusion pads must be installed independently of the extrusion rod without any connection with the extrusion rod, and...
