Full-automatic aluminum bar hot shearing machine

Abstract

The invention provides a full-automatic aluminum bar hot shearing machine applied to the technical field of aluminum profile producing and machining. A machining framework (2) on a hot shearing machine base (1) of the full-automatic aluminum bar hot shearing machine is provided with an aluminum bar channel (3). A top plate (14) above the aluminum bar channel (3) is provided with a main oil cylinder (4). A moving cutter base (6) is connected with the main oil cylinder (4). A shearing cutter blade (28) is installed on the moving cutter base (6). A fixed cutter base (7) is arranged on the portion, below the aluminum bar channel (3), of the machining framework (2). According to the full-automatic aluminum bar hot shearing machine, hot shearing operation of machining long aluminum bars into short aluminum bars can be completed conveniently, fast and automatically, cut openings of the short aluminum bars machined in a hot shearing manner deform little and are smooth, bubbles will not be generated in the extruding process, the surface quality of aluminum profiles is high, labor intensity of operators is reduced comprehensively, and the aluminum profile machining efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of aluminum profile production and processing, and more specifically relates to a fully automatic aluminum rod hot shearing machine, and also relates to an aluminum rod hot shearing method. Background technique [0002] At present, in the extrusion production of industrial aluminum profiles, the traditional aluminum profile production and manufacturing process is as follows: firstly, 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 pieces by a sawing machine. aluminum rod. Then the short aluminum rods are arranged and stacked on the conveyor chain of the heating furnace, heated to the extrusion temperature in the furnace, and finally the short aluminum rods are manually sent into the extruder to extrude the profile. In the manufacturing process in the prior art, the saw rod of the long aluminum rod ...

AI Technical Summary

Problems solved by technology

In the manufacturing process of the prior art, the saw rod of the long aluminum rod needs to be manually operated, and the saw blade needs to be replaced regularly, and the saw dust affects the yield rate, resulting in an increase in production costs

The length of the short rod does not always meet the requirements of each set of extrusion dies, and if the length is not suitable, it will affect the production scheduling and yield

In response to these problems, a hydraulic cold shearing machine has been developed on the market. At room temperature, the aluminum rod is cut into short aluminum rods with a hydraulic shearing machine, and then the short aluminum rods are heated in a short rod heating furnace and extruded. This method overcomes the kerf loss and saw blade loss when sawing aluminum rods, but the fracture deformation of the aluminum rod is large and uneven during cold shearing, and bubbles are prone to appear on the surface of the profile during extrusion, which affects the quality of the profile
