Description:
It is a highly efficient automatic hydraulically controlled band-saw with multiple material feed. The machine is designed for vertical and angular cuts. Angular cuts are fluently adjustable from 0 to +45 grades right in automatic mode and to +60° right in semiautomatic mode. It is suitable for serial production and thank to its robust construction enables to cut wide range of materials including stainless stells and tool steels both profiles and full materials.

Control system:

  • Machine is equipped with the control, programmable PLC MITSUBISHI FX5U. Blade drive is fully controlled by the frequency inverter MITSUBISHI.
  • The coloured touch screen MITSUBISHI GT 2104 enables easy communication with an operator. It shows working conditions (blade speed, moving to the cut, cutting parameters etc.)
  • The lenght and quantity are set by the control panel. Machine will optimize all next calculations itself. It is possible to set 15 different programms for quick lenghts setting.
  • Feeder drive: by hydraulics, magnetic tape and sensor.
  • Machine enables semi-automatic and automatic mode (all movements are controlled automatically).
  • Regulation of the shift speed (bow movement to the cut) is manual using a throttle valve laces beside the control panel. Automatical (safety) of the shift speed PEGAS BRP: Exceeding of set loading (in amperes) will stop the shift speed.
  • The controlling panel is on turning console. The panel is equiped with hardware button and digital display of the controlling system. The hardware buttons serves for controlling the of basic movements. The controlling panel is equipped with a safety button, which stops the saw, and another two buttons for turning it on. Buttons for machine movements handling are parts of high quality control keyboard.

Construction:

  • The machine is constructionaly designed in that way, so that it corresponds to standard exertions in productive conditions. That is why all carrying parts are made as cast-iron castings (solidity, absorbtion of vibrations and stops). Parts of arm, vice and turn table is cast iron.
  • The arm of the machine is made of cast iron and it is designed to ensure the power and the precision of the cut. Arm is 25 grades sloped, it increases the lifetime of blade.
  • Arm is placed in adjustable bearings.
  • Drive pulley and tighten pulley are both metal castings.
  • Upper working arm position controled by automatic stopper (DPP)
  • The down working position of the arm controlled by the microswitch. In the end position microswitch is on, arm goes to selected upper position.
  • The vice is welded. The jaw is made from steel. Jaw ensures the safe clamping of the material.
  • The hydraulically operating jaw vice with long travel is placed on linear leading.
  • Moving jaw of the vice is handled by long stroke hydraulic cylinder.
  • Very massive feeder moves using two sharpened bars and teflon cases.
  • There is a floating seating of the feeding vice in the feeder, it means that the feeding vice moves in perpendicular sense regarding the feeding sense. The stationary jaw of the feeding vice copies the possible roughness of feeded material and the worning out of mechanical parts of the feeder is eliminated.
  • The feeder moves the material to be cut to the main vice according to the set lenght that was adjusted by the operator in the controlling panel. The position of the feeder is indicated by electromagnetic sensor and measuring magnetic tape. For a perfect placing of a feeder , feeder moves to end positions by a slow velocity.
  • Indication of material in the feeder: optic sensor - it notices that there is a material in the feeder. If there is no material in the feeder, the signal reflects on the glass that is situated on movable jaw and it goes back to the sensor. The machine stops feeding and waits for another bar.
  • The feeder clamping vice is made from cast iron. Jaws ensure safe clamping of the material.
  • Hydraulic, long stroke cylinder of the feeder. Moving jaw of the vice is handled by long stroke hydraulic cylinder.
  • A turntable is massive welded. A turntable gives a big place for supportion of material and its perfect clamping.
  • Bow rotation to angular cuts is manualy as well as angle seting.
  • Angles (degrees are shown at the touch screen MITSUBISHI. Angle indication using incremental sensor and a magnetic tape.

Basic equipment of machine:

  • The blade leading in guides with hardmetal plates and leading bearings and along cast iron pulleys.
  • There is a guide situated on the firm beam on the drive side. On the tightening side there is the guide situated on the moving beam.
  • The guide beams of moving band guide is adjustable. Manual adjustment and fixing of the guide beams.
  • The saw-band is equipped with a guard, which protects the operator from millings and cutting emulsion.
  • Mechanic tightening of the blade.
  • Automatic indication of blade tension.
  • Passively driven cleaning brush for perfect cleaning and function of blade by roller.
  • Pulley drive the saw blade 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.
  • Cooling system for emulsion with liquid distribution to blade guides.
  • Massive base with a tank for chips. Base is designed for manipulation manipulation with machine by pallet truck and also by any hight lift truck.
  • Indication of blade tightening and opening of the cover.
  • Controlling 24 V.
  • Machine is equipped with hydraulic system which controles all functions of that maschine. It pushes the arm to cut, pulls up the arm, opens and closes vices, moving of feeder.

Basic accessories of machine:

  • Slide of cut pieces.
  • Band saw blade.
  • Set of spanners for common service.
  • Manual instructions in eletronic form (CD).

Operating cycle:
The machine automatically grips the material in the main vice and the feeder moves into a position determined by the processor (i.e. the required length of the cut and a constant added length); the feeder-vice’s jaw stays open. The arm moves into the cut; after cutting the material, it moves into the upper position. The feeder moves by the constant added length (exactly to a position determined by the processor) and the feeder jaw grips the material. The vice is released; the feeder moves the material into the zero position (by the required length). The main vice grips, the feeder-vice is released and the entire cycle is repeated.The operator only removes the sawn material.
