    Overview:

     The CNC metal band sawing machine series is suitable for sawing large quantities of materials of the same specifications, with stable performance and high efficiency; the man-machine interface replaces the traditional control panel mode, and the sawing parameters are digitally set. PLC programmable controller, flexible setting and changing sawing mode. Feeding positioning is controlled by grating ruler, positioning error is ± 0.2mm


    1. Main features and functions

     The machine tool is composed of the base part, the guide part, the main transmission system, the saw blade tensioning device, the feed positioning system, the hydraulic system, the electrical system, the protection device, the cooling system, etc .; through the cooperation of each part to execute a series of command actions to complete the material feed , Positioning and sawing.

    1.1 Base part

     The whole base is a box structure welded by A3 steel plate. The left side of the base is a hydraulic oil tank and the right side is a cooling water tank. After the base is welded, it is subjected to vibration aging treatment to remove the welding internal stress.

    1.2 Guiding part

     The guide part is divided into saw beam guide and saw blade guide part. The guide part of the saw beam is composed of two large-diameter uprights. It is guided by the lifting oil cylinder for sawing feeding and retreating. The reasonable structural layout makes the sawing guide more stable and more accurate. The saw blade guide is composed of a pair of guide arms and a guide head. The guide head twists the saw blade wound on the rim of the saw wheel into a perpendicular state to the worktable surface, so that the cutting material has a high degree of verticality.

    1.3 Main drive system

    The main transmission system consists of a worm gear reducer, a V-belt pulley, and a main motor. The worm gear is made of tin bronze material and is processed on a precision gear hobbing machine with a precision worm gear hob. After the worm is quenched, it is ground on a precision worm grinder, with a high surface finish and high precision. The box body adopts HT250 cast iron, with the special boring die to ensure the machining accuracy, and the worm gear has a long service life. The output end of the worm gear box is connected with the driving wheel, and the driven wheel is driven to rotate by the saw blade wound on the rim to perform rotary cutting.

    1.4 Saw blade tensioning device

     It consists of a tensioning handle, a tensioning screw tensioning carriage, a tensioning slider, a hollow adjusting screw, etc .; the tensioning screw can be used to tension and loosen the saw blade and replace the saw blade; through the hollow adjusting screw, Adjust the angle relationship between saw wheel and beam plate.

    1.5 Feeding positioning system

     The feeding positioning system consists of feeding bed, linear guide rail and roller. The positioning is controlled by grating ruler, and the positioning error is ± 0.2mm. When the sawing setting data is sent, the feeding is stopped and sawing is performed. One-time feeding stroke: 420mm

    1.6 Hydraulic system

     The hydraulic system is composed of hydraulic motor, pump, solenoid valve, speed control valve, oil cylinder, oil pipe and oil tank, etc., through the command output of the electrical system to complete the actions required for sawing.

    1.7 Electrical system

     The electrical system is composed of transformer, contactor, touch screen, PLC, relay, proximity switch, wire and switch. By inputting data and parameter settings in the touch screen, and cooperating with the hydraulic system, it can complete a series of required actions for sawing.

    1.8 Protection device

     The protection device is divided into safety protection and electrical system protection. The safety protection device includes saw wheel protective cover, belt wheel protective cover and other facilities. These facilities are personal safety protection facilities and cannot be removed at will. Electrical system protection includes main circuit overload protection, motor overload protection, and saw blade breakage shutdown protection.

    1.9 Cooling system

      The cooling system is divided into sawing cooling and hydraulic oil cooling. The cooling liquid is pumped to the cooling pipe through the cooling pump to cool the saw blade and wash the sawdust to make the sawing smoother. Hydraulic oil cooling The hydraulic oil flowing back through the oil return pipe passes through the cooler and then returns to the hydraulic oil tank, so that the oil temperature remains stable during the work and does not rise to ensure the normal and stable operation of the hydraulic system.

    2.0 Chip removal system

    Chip removal system: automatic chip removal system, iron chips are automatically discharged through the chip removal mechanism, which is convenient for users to clean the iron chips. The chip evacuation system uses a hydraulic motor to drive the rotating shaft for circular motion, and iron chips are discharged with the rotating shaft. Hydraulic control of chip removal speed, stepless speed regulation
