GZ4232 Technical Information

    GZ4232 is a new type of sawing machine specially developed for learning the German brand PEHAPAD single-column single-cylinder structure, combined with its professional 20-year R & D experience for the die steel cutting industry.

     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 adopts magnetic scale, positioning error is ± 0.2mm.

    1. Main features

    1. Single hydraulic cylinder design, combined with a large column and an auxiliary column to form a stable sawing structure.

    2. Stable cutting and high precision.

    3. The work clamp adopts hydraulic pressure, which is easy to operate.

    4 Digital display of work efficiency, simple and clear work process.

    5. The surface of the guide cylinder where the saw beam is installed is chrome plated + ground. The precision of the matching gap of the guide copper sleeve is matched with a precise small gap at the factory to ensure stable feeding during sawing.

    6. All hydraulic valves are equipped with Taiwan and other brands to ensure smooth cutting operation.

    7. The front protection also satisfies the prevention of emulsion splashing and overflowing to the workshop floor.

    8. The saw blade angle torsion device should meet the requirement that the front torsion bearing adopts a flexible structure, and the rear end uses a hard alloy rigid guide wheel, and has high precision to ensure that the saw blade runs smoothly during the cutting process.

    Second, the main structure

     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.


    2.1 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.

    2.2 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 a large-diameter column and an auxiliary square column. The lifting oil cylinder is used to guide the sawing feeding and retracting. 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.

    2.3 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.

    2.4 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.

    2.5 Feeding positioning system

     The feeding positioning system consists of a feeding bed, a cylindrical guide, a roller, and a special magnetic scale for the sawing machine. When the sawing setting data is sent, the feeding is stopped and sawing is performed. One-time feeding stroke: 420mm,

    2.6 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.

    2.7 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.

    2.8 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.

    2.9 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.
