Problems solved by technology

Although the structure of the centering crank slider mechanism is simple and the manufacturing cost is low, the speed curve of the centering crank slider mechanism is close to a sinusoidal curve. When driving the inclined blade cutter to shear the plate, the speed changes greatly at different positions, and the quality of the incision is not uniform. It is often necessary to increase the process to process the incision, which greatly increases the production cost; in addition, the centering crank slider mechanism has no quick return characteristics, and the shearing plate can be used with a short stroke

Abstract

The invention relates to a mechanical plate shearing machine, in particular to a mechanical plate shearing machine utilizing a swing guide rod mechanism. The structure is that a cover plate is fixedly installed at the upper end of a lateral support I and a lateral support II of the plate shearing machine. T-shaped supports are symmetrically installed at two ends on the lower side of the cover plate, the upper ends of the T-shaped supports are fixed with the cover plate, and the lower ends of the T-shaped supports are sleeved on two sides of a spindle in empty mode. Execution mechanisms are symmetrically installed on the spindle section between the lateral support I and one T-shaped support and between the lateral support II and the other T-shaped support. The mechanical plate shearing machine has the advantages of being novel in structure, convenient to modify, low in cost, safe, good in economy and safety and the like, thereby being a novel mechanical plate shearing machine integrating economy and practicability.

Description

technical field [0001] The mechanical shearing machine of the present invention relates to a mechanical shearing machine utilizing a swing guide rod mechanism. Background technique [0002] The current mechanical shearing machine uses a centering crank slider mechanism as an actuator, the main shaft drives the eccentric wheel to rotate, and the connecting rod drives the cutter to perform shearing motion. Although the structure of the centering crank slider mechanism is simple and the manufacturing cost is low, the speed curve of the centering crank slider mechanism is close to a sinusoidal curve. When driving the oblique blade cutter to shear the plate, the speed changes greatly at different positions, and the quality of the incision is not uniform. It is often necessary to increase the process to process the incision, thereby greatly increasing the production cost; in addition, the centering crank slider mechanism has no quick return characteristic, and the available stroke...
