Apparatus for continuous extrusion |
摘要 |
Apparatus for continuous extrusion has a rotatable wheel with an endless groove therein, a relatively stationary shoe member overlying part of the groove lengthwise, a portion of the shoe member projecting part way into the groove and being constituted at least partly by a die assembly which includes a separate and replaceable abutment member which projects into the groove to block it. The die assembly can have separate and replaceable components constituting a feed chamber, a die throat, and optionally a mandrel supported in the die throat for producing tubular extrusion products. Cooling of the die assembly is also envisaged.
