Abstract

The invention relates to the field of aluminum profile extruders, in particular to an anti-rotation device and an anti-rotation method for a cylinder barrel of a pushing oil cylinder of an extruder. The anti-rotation device comprises a mounting seat, a pushing oil cylinder assembly and a locking mechanism, wherein the pushing oil cylinder assembly is mounted on the mounting seat, the locking mechanism for locking the pushing oil cylinder assembly on the mounting seat are fixedly mounted on the mounting seat, the pushing oil cylinder assembly comprises the cylinder barrel, a piston rod, an inner copper sleeve, a front end cover, a front flange, a rear end cover, a rear flange, a piston and a rear end cover, one end of the cylinder barrel penetrates through the mounting seat, the cylinder barrel is detachably connected with the locking mechanism, and external threads are formed in two ends of the cylinder barrel. According to the anti-rotation device for the cylinder barrel of the pushing oil cylinder, four states of anti rotation of the cylinder barrel of the pushing oil cylinder are carried out by four locking mechanisms, so that the cylinder barrel of the pushing oil cylinder is prevented from rotating, the production quality of the aluminum alloy is improved, the situation that the cylinder barrel rotates to generate flaws is avoided, and the production stability is improved.

Description

technical field [0001] The invention relates to the field of aluminum profile extruders, in particular to an anti-rotation device and anti-rotation method for an extruder pushing an oil cylinder. Background technique [0002] When the cylinder barrel of the push cylinder in the aluminum profile extrusion machine is in normal use, the rotation of the cylinder barrel often affects the stability of production, which in turn makes the surface of the processed aluminum alloy have flaws.
