Aluminum rod hot shear mechanism with high stability

Abstract

The invention relates to the field of aluminium profile processing equipment, and in particular discloses an aluminium bar hot-shearing mechanism having high stability. The aluminium bar hot-shearingmechanism having high stability comprises a lower shearing moving blade device used for cutting off an aluminium bar; an upper bar pressing device used for compressing the aluminium bar is arranged atone side of the lower shearing moving blade device; a fixed blade base is arranged below the upper bar pressing device; a lower bar supporting device used for supporting the aluminium bar from belowis arranged below the lower shearing moving blade device; and a channel for the aluminium bar to pass is arranged among the lower shearing moving blade device, the upper bar pressing device, the lowerbar supporting device and the fixed blade base. The stability of the scheme is high; and, due to a push cylinder away from the high temperature part of a hot shearer, and the upper bar pressing device and the lower bar supporting device in pure mechanical transmission, influence of adverse factors due to a high-temperature environment is obviously reduced.

Description

technical field [0001] The invention relates to the field of aluminum profile processing equipment, in particular to an aluminum rod hot shearing mechanism with high stability. Background technique [0002] Hot shear is a hot shear device, which is widely used in the field of metallurgy. For example, the die-casting of aluminum profiles requires the use of hot shears. When the hot shears cut the aluminum rod, the cutting edge of the material is from top to bottom. At this time, above the aluminum rod, it is necessary to set an upper pressing rod mechanism that can press the aluminum rod and move downward with the cutting edge at the same time, and an upper pressing mechanism that can support the aluminum rod from below and move downward with the cutting edge at the same time. The lower supporting rod mechanism that moves downward prevents the aluminum rod from tilting due to the lack of strong and stable support above and below the aluminum rod, resulting in uneven cutting e...

[0002] Hot shear is a hot shear device, which is widely used in the field of metallurgy. For example, the die-casting of aluminum profiles requires the use of hot shears. When the hot shears cut the aluminum rod, the cutting edge of the material is from top to bottom. At this time, above the aluminum rod, it is necessary to set an upper pressing rod mechanism that can press the aluminum rod and move downward with the cutting edge at the same time, and an upper pressing mechanism that can support the aluminum rod from below and move downward with the cutting edge at the same time. The lower supporting rod mechanism that moves downward avoids the aluminum rod from tilting due to the lack of strong and stable support above and below the aluminum rod, resulting in uneven cutting edge position of the aluminum rod

[0003] A hot shearing machine structure (CN2015204591301.1) and an aluminum rod hot shearing machine (201820911477.9) represented in the prior art documents both use a hydraulic cylinder and a top block connected to the hydraulic cylinder to realize pressing and supporting rods. function, although the structure is simple, there are still many problems in the process of use. For example, the existing structure of the rod pressing mechanism directly uses the upper oil cylinder to press the rod. Because the temperature of the aluminum rod to be sheared is very high, In order to reduce the stroke distance, the oil cylinder is often installed very close to the cutting edge of the high-temperature aluminum rod. The operating environment is harsh. The pressure rod structure of the oil cylinder is prone to oil leakage and jamming in the high-temperature and harsh environment. The poor stability of the structure will bring a lot of difficulties to the later maintenance work, and frequent maintenance work will also bring unnecessary safety hazards to the operators
