A sizing mechanism of aluminum rod hot shearing machine

Abstract

The invention relates to a sizing mechanism of aluminum bar hot shears. The sizing mechanism comprises a sizing rack (10.1). The sizing rack (10.1) is provided with a sizing frame (10.2) which can move forward and backward, a fixed support base (10.3) is arranged on the front side of the sizing frame (10.2), a sizing stop bar assembly (10.4) is hinged to the fixed support base (10.3), a cylinder frame (10.5) is arranged on the back side of the sizing frame (10.2) and provided with a cylinder base (10.6), a first cylinder (10.7) is hinged to the cylinder base (10.6), and the first cylinder (10.7) and the sizing stop bar assembly (10.4) are connected through a connecting rod mechanism (10.8). When the sizing stop bar assembly is collided by an aluminum bar, and a first connecting rod and a second connecting rod are located at dead point positions so that the sizing stop bar assembly in the sizing process can be effectively prevented from being deflected, and the positioning accuracy of aluminum bar sizing is greatly improved.

Description

technical field [0001] The invention relates to a length-setting mechanism of an aluminum rod hot shearing machine, which belongs to the technical field of aluminum profile production equipment. Background technique [0002] At present, the aluminum rod extrusion machine is mainly used to produce profiles of different specifications. At present, in the extrusion production of industrial aluminum profiles, the traditional manufacturing process is as follows: first, the aluminum ingot is melted and cast into a long aluminum rod with a length of about 6 meters to 8 meters, and then the long aluminum rod is sawed into short aluminum rods by a sawing machine , and then arrange and stack the short aluminum rods on the conveyor chain of the heating furnace, heat them into the furnace to the extrusion temperature, and finally send the short rods into the extruder manually to extrude the profile. In the existing manufacturing process, the sticking of long aluminum rods requires manu...

Problems solved by technology

[0004] 1. When the heating furnace transports the aluminum rod to the sizing mechanism, because the weight of the aluminum rod is relatively heavy and has a large inertia, the front end of the aluminum rod will generate a large impact force when it reaches the stopper. The strength is not enough to ensure the stability of the swing arm, so that there is a certain degree of rotation deviation of the swing arm, which affects the positioning accuracy of the aluminum rod;

[0005] 2. The sizing mechanism relies on the slider and the chute to cooperate. Because there is an inevitable gap between the slider and the chute, the slider of the sizing mechanism will vibrate when it slides and collides with the aluminum rod, which affects the positioning of the aluminum rod.
