SEMIAUTOMATIC BAND SAW MACHINE:     

pásová pila na kov Pegas 350x400 SHI-LR-F

Semiautomatic machine with hydraulic manipulation.
The machine is designed for cutting of material in vertical and angle cuts, angle cuts are possible to set fluently rom 45° left to 60° right. Change of angle using quick clamping handle.  The angles indicated on the digital display show the displacement of the turntable.
It is suitable for piece production and small series production. Thanks to its rugged construction it enables cutting of wide range of materials including stainless steels and tools steels as well as profiles and full materials.

Construction:

• The machine is  constructionaly  designed in that way, so that it corresponds to extreme  exertions in productive conditions.
• The arm is provides the necessary performance and accuracy of cutting. The arm is rotated by a shaft (joint), which is supported by adjustable conical bearings.
• Rapid traverse of the arm away from the cut
• The drive and tensioning pulleys are cast pieces.
• Working positions of the arm are controlled by the cam and microswitches of the upper and down position of the arm. In the end position microswitch is on, arm goes to selected up position.
• The vice is made of cast iron and the jaws allow a safe grip. The hydraulically controlled vice with short travel is situated in an adjustable dovetail groove. The adjustment is manual with a wheel and trapeze thread.  The vice jaw travels left-right with regard the angular cut; it is secured by a crank.
• The turntable provides enough space for supporting and gripping the material. The turning table has autoarresting every 15 grades ( the groove with the spring ). The angles indicated on the digital display show the displacement of the turntable.
• Model with STOP function – cutting : it enables to stop cutting by pressing STOP button at any time. The arm goes up with the running blade without stopping the machine and without opening the vice.
• Leading of blade in hard-metal plates.
• The sawing machine is equipped with an electromechanical device, which monitors the band tension and a limit switch, which secures the machine against slack band.
• The saw-band is equipped by a guard, which protects the operator from millings and cutting emulsion.  
• Mechanic tightening of the blade.
• The cleaning brush for perfect cleaning and function of blade.
• Drive of machine is solved by worm gear box with maintenanceless oil filling. Three-phases electromotor  with double winding, with  a frequency converter  for a fluent regulation of the blade speed from 20 to 100 m/min. Sturdy flange with shaft. Termoprotection of engine.
• The cooling system distributes cutting emulsion to the band guides.
• Robust base with a tank for chips.
• Indication of  blade tightening and opening of the cover
• Controlling 24 V
• The main switch is located on the front door. There is equipped with a safety button, which stops the saw. There is also a feed regulator and buttons, which control the various available movements, and digital display indicating displacement of the turntable.
• Maschine is equipped by hydraulic system that manipulates all functions of that maschine. It presses the arm to cut, pulls up the arm and opens and closes vices.

Basic equipment of machine:

• blade
• set of tools
• manual instructions

Operating cycle:
After manual adjustment of the jaws and the arm’s operational positions the operator starts the cycle with a switch on the control panel. The hydraulic cylinder of the vice grips the material and the saw starts working. The cutting speed of the arm is controlled by a throttle valve. After finishing the cutting, the arm reaches its top operational position and the band drive stops. The vice opens and the operator can handle the material.The control system monitors correct ten
