Over Crank Shearing Machine (Mechanical / Pneumatic Clutch)

FRAME

Rigid steel frame of Weldor Shears are optimally designed to avoid weak sections and is of interlocked design. The ram is guided throughout its length by accurate machined guideways ensuring proper clearance and clean cut.

CLUTCH, BRAKE & DRIVE

Revolving type Clutch & Brake with the Main Gear engages every time when foot pedal is pressed. Drive provided through V-Belt & all journals are fitted in Gun-Metal Bearings. Brake is adjustable and incorporated on end of Crank Shaft.

HOLD-DOWN SYSTEM

Hydraulic Hold down pads are actuated by Hydraulic power pack / cam operated hold down pads hold the sheet securely to avoid slipping and bowing resulting in clean square cut. Hold down units are provided with oversize pads to avoid impressions on sheet metal on request.

BLADES

Weldor Shears are provided with high quality single segment (HcHcr) Blades for longer tool life. Ease in assembling of knife reduces down-time. The shear blades are four edged.

LUBRICATION

All bearing parts and guide surfaces are lubricated through hand-operated lubrication system.

MECHANICAL BACKGAUGE

This is a standard equipment provided on all Weldor shears. Scale on the backgauge gives instantaneous reading of distance between shear and back gauge. Thus avoiding errors and maintenance encountered in electronic equipment.

FINGER GUARD

Fitted in front of hold-down for operator protection without obstructing viewing.
