Actuating mechanism of mechanical shearing machine

Abstract

The invention discloses an executing mechanism of a mechanical plate shearing machine and relates to the executing mechanism used on a mechanical plate shearing machine. The executing mechanism of the mechanical plate shearing machine is characterized in that eccentric wheels are symmetrically arranged on a main shaft between the side bracket of the plate shearing machine and the T-shaped frame; an eccentric wheel slot is machined on the inner part of a swinging block shell; the eccentric wheels are placed in the eccentric wheel slot and connected with the eccentric wheel slot in a sliding friction manner; two sealing covers are fixed at the two sides of the swinging block shell, respectively; arc-shaped main shaft slots are machined on the sealing covers; the main shaft slides in the arc-shaped shaft slots relative to the sealing covers; narrow ends of the sealing covers are hinged with the upper end of a connecting rod on the plate shearing machine; one end of a rotor I is fixed at the outer sides of the sealing covers; and the other ends of the rotator I are hinged with the lower end of the T-shaped frame on the plate shearing machine. The executing mechanism of the mechanical plate shearing machine has the characteristics of being novel in structure, simple to modify, low in cost, safe and reliable, good in economical efficiency and safety and the like, and therefore, the executing mechanism of the mechanical plate shearing machine is integrated with economical efficiency and practicability.

Description

technical field [0001] The actuator of the mechanical shearing machine described in the present invention relates to an actuator used on the mechanical shearing machine. 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 availa...

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
