A kind of aluminum bar hot shear processing equipment

Abstract

The invention relates to the field of aluminum profile processing equipment, and in particular discloses aluminum bar hot shearing processing equipment. The aluminum bar hot shearing processing equipment comprises a roller conveyor belt for conveying aluminum bars. A lower shearing power device for cutting off the aluminum bars is arranged on one side of the advancing direction of the roller conveyor belt, an upper bar pressing device for compressing the aluminum bars is arranged on the side, close to the advancing direction of the roller conveyor belt, of the lower shearing power device, a fixed tool apron is arranged below the upper bar pressing device, a lower bar supporting device which supports the aluminum bars below is arranged below the lower shearing power device, and channels where the aluminum bars pass are arranged between the lower shearing power device and the upper bar pressing device and between the lower bar supporting device and the fixed tool apron. The aluminum barhot shearing processing equipment is characterized in that the lower shearing power device comprises a slicer which is connected to a push block which drives the slicer to move up and down, so that problems of easy oil leakage and jamming of oil cylinder pressure bar and supporting bar structures in a high-temperature severe environment in the prior art can be overcome well, the occupied space bya fixed size device can be reduced obviously, and a compact and efficient effective effect is achieved.

Description

technical field [0001] The invention relates to the field of aluminum profile processing equipment, in particular to a hot-shearing processing equipment for aluminum rods. 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 edge p...

[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] The sizing device on the existing aluminum rod shearing machine also uses an oil cylinder to drive the sizing head to rotate. Since the sizing head is impacted by the aluminum rod with a greater force, the impact force has a more direct effect on the oil cylinder. After working for a long time, it is easy to The oil cylinder is damaged and leaked, and the oil cylinder needs to work in a high-temperature environment for a long time, which further aggravates the risk of damage and oil leakage, which will also lead to a significant shortening of the service life of the sizing device

[0004] For example, a kind of aluminum rod hot shearing processing equipment structure (CN2015204591301.1) and a kind of aluminum rod hot shearing processing equipment (201820911477.9) represented in the prior art documents are both realized by a hydraulic cylinder and a jack block connected to the hydraulic cylinder. Although the structure is simple, there are still many problems in the use process. For example, the existing structure of the pressing rod mechanism directly uses the upper oil cylinder to press the rod. Because the aluminum to be hot-sheared The temperature of the rod 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 used oil cylinder is prone to oil leakage, Problems such as jamming and poor structural stability will bring many difficulties to the later maintenance work. Frequent maintenance work will also bring unnecessary safety hazards to operators
