Description

Technical Field

[0001] The present invention relates to the technical field of shearing machines, and in particular to a tail handle shearing machine which is easy to repair and maintain. Background Art

[0002] A shear is a mechanical device used to cut metal materials. During the rolling process, large-section ingots and billets become smaller and longer after rolling. To meet the requirements of subsequent processes and product dimensions, shearing is a necessary step in all steel production processes.

[0003] The shank shear is a device specifically designed for shearing specimen shanks. It is widely used in metallurgy, aviation, aerospace, quality inspection, universities, and the automotive industry. Its main function is to shear specimens with shanks to facilitate subsequent transportation, sample preparation, and analysis.

[0004] At present, the existing technology still has the following areas for improvement: the existing tail handle shearing machine requires manual installation of the sample, and the installation opening of the sample is usually small, and manual installation cannot reach the precise position. In addition, long-term repetitive operation will easily cause fatigue to the personnel, resulting in a slowdown in production speed. The parts of the existing equipment are usually exposed, which can easily lead to damage to the parts over a long period of time. The tool is operated by rotation, which is difficult to perform maintenance operations. The blanks after shearing also need to be manually moved. The weight of the blanks is heavy, which can easily cause injuries to people. Summary of the Invention
