Self-adjusting plate shearing machine

Abstract

The invention relates to the technical field of metal machining, and discloses a self-adjusting plate shearing machine. The self-adjusting plate shearing machine comprises a material pressing cylinder, a moving body and a gap cylinder are installed on one side of the material pressing cylinder, a material pressing rod is movably sleeved with the material pressing cylinder, a series connection pipe is fixedly connected to an outlet in the bottom end of the material pressing cylinder, a gap adjusting rod is movably sleeved with the gap cylinder, and a protruding block is fixedly connected to the center of the bottom of the left side of the gap cylinder. Through the designed material pressing cylinder, the series connection pipe and the gap cylinder, when the material pressing cylinder presses a plate, oil can be synchronously supplied to the gap cylinder through the downward pressing distance, so that the moving body with an upper blade can move proportionally according to the thickness of the plate, and the blade gap can be accurately and automatically adjusted according to the thickness of the plate; and meanwhile, through an designed adjusting lead screw, when the blade gap is self-adjusted, the adjusting lead screw can be influenced by movement of the moving body, and self-adjustment of the shearing angle of the upper blade is completed.

Description

Technical field [0001] The present invention relates to the field of metal processing, and is specifically a self-regulated shearing machine. Background technique [0002] The shearing machine is a machine that cuts a metal sheet from a demand, and the shear principle is mainly to form a shear force by fixing the lower blade and the active upper blade, thereby cutting the metal sheet. [0003] Among them, the metal plates of different thicknesses require the blade gap between the blade and the lower blade, and the shear angle is different. The blade gap required by the thick plate material is large, and the shear angle, this is to increase shear force, reduce The deformation of the small shear region, the ratio of the blade gap and the thickness of the sheet is about 0.08 mm: 1 mm, while the shear angle is between 0.5 degrees and 2 degrees, and the existing shear machine for the blade gap, shearing angle Adjustment, it is necessary to manually measure the thickness of the sheet, ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing shearing machine proposed in the background technology, the present invention provides a self-adjusting shearing machine, which can automatically detect the thickness of the plate for fixing the plate, self-adjust the gap between the cutters, and self-adjust the shearing angle. The advantage of adjustment solves the problem of manually measuring the thickness of the plate by the shearing machine in the above background technology to manually adjust the tool gap and shear angle
