Aluminum strip shearing device

Abstract

The utility model discloses an aluminum bar shearing device, and the utility model relates to the technical field of aluminum bar processing equipment. The aluminum bar shearing device first unfolds a measuring ruler, and slides a connecting sleeve and a positioning plate to corresponding positions, so that the aluminum bar passes through the inside of the aluminum bar through groove, and one end abuts against the positioning plate, thereby completing the positioning work of the shearing length of the aluminum bar, which is beneficial to improving the convenience of using the aluminum bar shearing device. When the measuring ruler fits the limit block, a second spring drives the limit piece to slide upward, so that the arc surface of the limit piece fits and extrude the measuring ruler, which plays a fixing role on the measuring ruler and avoids the sliding deviation of the measuring ruler, which is beneficial to improving the accuracy of the measurement work. After the aluminum bar is positioned, the extrusion block is driven to rotate by pressing the extrusion rod, so that the extrusion block extrudes downward and pushes the shearing block, thereby completing the shearing operation of the aluminum bar. Finally, the slider and the first spring are used to restore the shearing block to an initial state, which is beneficial to ensuring the flatness of the aluminum bar shearing and improving the work quality and work efficiency.
