Description

Advantages

KNUCKLE JOINT PRESS is ideal for manufacturing high precision parts. Material saving compared to conventional machining process is 40% or More. Because of high surface finish & accuracy, these cold formed parts are in increasing demand.

General Features

KNUCKLE JOINT PRESS is ideal for forming operation where close tolerance is required. It is designed for operations requiring slow but high force at lower zone of the stroke, suited, therefore for coining, extruding, sizing, embossing and thick plat blanking. By virtue of the linkage system, the ram speed is very low as it approaches BDC. This feature enables forming of different shapes.

Bed Knockout Device

The Knockout Device is installed beneath bolster of bed for taking work pieces out of the tooling. It is activated by a driving rod, which is connected to the crank driving eccentric rolling shaft.

Slide

The Slide both upper and lower are single cast steel pieces hinged to upper link and lower link respectively through pins housed and profusely lubricated inside the slides. One pair of pneumatic cylinders counter balances the self weight of lower slide. The lower Slide is provided with knockout bar, generally one number. Unlike other presses, the slide adjustment mechanism is on the top—one fixed to side and the other is moved (Slides) horizontally either manually or through an electric motor drive.

Drive

The Shaft is made of Forged carbon Alloy Steel, Gear in Cast Steel and Pinion in forged alloy steel. All pins are of forged carbon alloy steel. Teeth are made helical for higher capacity presses. All bearing and contact surfaces are ground.

Slide Knuckle Joint Mechanism

Slide is connected to crank by two pieces of linked knuckle joints, its weight is offset by the adjustable pneumatic counter balancer. This mechanism is to transit the revolution of crank to drive the slide for the movement of up and down strokes.

Optimized slide movement with modified knuckle-joint drive.
High level of repetitive accuracy even with fluctuating material thicknesses and strengths
Reduced cutting impact because of system rigidity.
Long die service lives
Low impact noise and reduced noise levels.
