Advantages and Disadvantages of the Rigid Clutch in Plate Shearing Machines

The working principle of plate shearing machine: is to convert circular motion into linear motion, by the main motor output, drive the flywheel, through the rigid clutch drive gear,

crankshaft (or eccentric gear), connecting rod operation, to achieve the linear motion of the slider, from the main motor to the connecting rod movement for circular motion.

The connecting rod and the slide block need to have circular motion and linear motion of the transfer point,

its design roughly have two kinds of mechanism, one is the ball type, one is the pin type (cylindrical), through this mechanism will be circular motion into the linear motion of the slide block.

The material pressure shearing machine, the plastic deformation, and get the required shape and precision,

so you must cooperate with a set of mould (upper die and lower die), the material placed in the meantime, the pressure on the machine,

make its deformation, and hours upon material caused by the force of reaction, the punch machine absorbed by the body.

Clearance noise of working mechanism. The crank connecting rod slider mechanism of punch press has three pairs of friction:

crankshaft journal and crankshaft tile; Crank neck and connecting rod big head bearing bush;

Connecting rod small head (ball head) and slider ball head seat. Due to manufacturing and assembly errors and work requirements,

there are inevitably gaps between them. When they move each other from free movement to contact movement, woodworking band saw is bound to bring strong impact.

This kind of noise has wide frequency band and strong high frequency part. The larger the gap, the higher the noise.

In addition, when the clearance is constant, the higher the stroke times of the slider, the higher the noise ratio.
