Novel discard shearing device of aluminum profile extruding machine

Abstract

The invention relates to a novel discard shearing device of an aluminum profile extruding machine. The novel discard shearing device comprises a shearing mechanism and a discard striking mechanism. The shearing mechanism is composed of a shearing telescopic cylinder, a shearing rod and a shear knife. The shear knife is installed at the bottom of the shearing rod in a swinging manner, is located at the position of an extrusion mold inlet of the extruding machine and is driven by the shearing telescopic cylinder to move up and down to conduct shearing. The shear knife is provided with a return mechanism. The discard striking mechanism is composed of a discard striking telescopic cylinder and a material push rod. The discard striking mechanism is installed on the shearing rod. After shearing is completed, the discard striking telescopic cylinder drives the material push rod downwards. A telescopic cylinder for secondarily driving the material push rod is formed by the discard striking telescopic cylinder on the shearing rod. When the novel discard shearing device is applied, it can be completed avoided that the shear knife of the shearing device can be pulled to a shearing face or an extrusion mold when retracted (returned), and in this way, flatness of the shearing face of an extruded profile can be effectively improved, the shearing precision can be improved and it can be avoided that the extrusion mold is damaged.

Description

technical field [0001] The invention relates to an aluminum profile extruding machine, in particular to a shearing device of the aluminum profile extruding machine. Background technique [0002] After the aluminum profile extrusion machine extrudes the profile, it is necessary to use a shearing device to shear the excess pressure after extrusion. The current shearing is mainly to push the shearing knife to stick to the extrusion die of the extrusion machine through the shearing rod. The entrance shears the remaining material of the extruded aluminum material rod, and since the shearing knife is fixed on the shearing rod, when the shearing knife of the shearing device retracts (returns), it is usually dragged to the The cut surface of the cut profile is even dragged to the extrusion die, which not only affects the flatness of the cut surface of the extruded profile, that is, affects the cutting accuracy, but may also damage the extrusion die.
