Extensible portable plate shearing machine feeding table
Technical Field
The invention relates to the technical field of plate shearing machines, in particular to an extensible portable plate shearing machine feeding table.
Background
A plate shearing machine is a machine for shearing a plate by using a blade to do reciprocating linear motion relative to another blade. The metal plates with various thicknesses are applied with shearing force by a reasonable blade gap through a movable upper blade and a fixed lower blade, so that the plates are broken and separated according to the required size. A plate shearing machine belongs to one of forging and pressing machines and mainly plays a role in the metal processing industry.
For a traditional small pedal type plate shearing machine, a user needs to step on the traditional small pedal type plate shearing machine by a manual foot, then a hydraulic cylinder is started, a blade is pressed downwards to perform plate shearing operation, when the plate is sheared, a steel plate to be sheared needs to be placed at the front stage of the plate shearing machine, then the plate is sheared step by step, however, due to the fact that the length of the front stage of the plate shearing machine is limited, when a long steel plate needs to be sheared, the user needs to hold the steel plate by hand to prevent the steel plate from falling due to unstable gravity, the front end of the steel plate is placed in a suspended mode, and bending deformation of the steel plate can.
