WELDOR ENGINEERING PVT. LTD.

HYDRAULIC SHEARING MACHINE

"WELDOR" Hydraulic shearing machine with  variable rake angle have been designed an developed through structural analysis technique for continuous production , accuracy and repeatability.

1. FRAME : Rigid steel frame of WELDOR shears are optimally designed to avoid weak sections at load support and is interlocked design.  The table of frame is welded together with support of sheet plates. The table top surface is machined with provision of t-slot to facilitate front gaugestopper. Ram assembly is welded with steel plate support

2. RAKE ANGLE (VARIABLE) :  Rake angle selector switch is provided to vary the rake angle. It permits to shear higher thickness than its capacity. Thin sheet can be cut w/o distortion.

3. ROLLER GUIDES : The upper beam is guided by three point roller guides. A replaceable hardened liner is provided for minimum wear. It eliminates lubrication of guides.

4. HYDR. POWER PACK : Hydraulic system is mounted at top rear side of machine. Hydraulic components are of internationally reputed make like vickers, Dowty, Rexroth etc. Valves are mounted on a compact manifold block minimizing piping  and chance of leakage. For oiling  cooling sufficient size of oil reservoir is provided.

5.CYLINDERS: Cylinders are precisely honed and are fitted with hard chromed piston rod with best quality sealing elements. Cylinders are connected with upper beam(cutting beam) with spherical bearings for higher capacity. Two cylinders are working on differential pressure principle  for synchronization. This eliminates force on cutting  edge.

HYDR. HOLD DOWN : Hydraulic hold down pads hold the sheet securely to avoid slipping & bowing resulting in clean square cut. Hold down units are provided for better clamping while cutting narrow strips.

BLADE CLEARANCE : Blade clearance  can be adjusted manually by lever on each side of machine with calibration of clearance suitable for thickness.

MOTORIZED BACK GAUGE : Motorized back gauge is operated from front of machine by push button. Back gauge traveled distance is displayed on electronic counter. Next position can be preset and can run with auto stop arrangement.

BLADES : Weldor shears are provided with high quality, Single segment HC HCR blades for longer tool life. Ease in assembly of blade reduces down time. The blades are four edged.

OPERATIONS : Electric panel is provided at right side and push button pendent with swival arm is provided at right hand side for easy operation by operator.Pendent is provided with on-off push button , 3 phase indicator , forward reverse push button , For   back gauge operation. Inch push button for individual hold down function and emergency stop push button is provided,Foot  switch is provided to carry out shearing operation if foot switch is pressed hold down plungers come down & then upper beam starts shearing operation. If foot switch is released  at any point of shearing upper beam will return from the point.

FINGER GUARD : Fitted in front of hold down for operator' protection without obstructing viewing.
