The driving wheel and the driven wheel blade, saw blade cutting direction by the rail control rack control. By adjusting the rotation bearing the band saw blade adjusting straightening after sweeping cut the sawing away. By the hydraulic cylinder piston rod support rail control frame falling into sawing, sawing machine is equipped with a manual or hydraulic clamping and locking mechanism, and the hydraulic control valve switch.Physical construction： The main components of sawing machine with sitting; bed, column; the saw beam and the transmission mechanism; guide device; clamping; tensioning device; the feeding frame; hydraulic transmission systems; electric control system; lubrication and cooling system;Foundation： The box structure base is welded of steel plates, the bed, the column is fixed on the base cavity, the larger space, front left for the electric button control box, for electrical distribution box on the right side of the hydraulic oil tank, the steel plate welded, cavity is provided with a hydraulic station, hydraulic line, right side cutting coolant tank and pump the bottom four corners, foundation bolt.Lathe bed： The bed is cast iron, is fixed on the pedestal, column by column size, round column as a saw frame moving guide rail, is used to support the saw beam lifting movement, and ensure the accurate orientation, small cylindrical play a supporting role, so as to ensure the normal cutting blade. The middle clamping vise and manual feeding mechanism, have to undertake the work table finished parts connected vise clamping device for the front, left side of the clamping screw rod through the hydraulic clamping cylinder rod inner hole, turn the handwheel or press the button, the left jaw movement to the left or right.The saw beam and the transmission mechanism： Made of thick steel plate cutting and welding, good rigidity, the right side is fixed with a worm gear box, the gear box is fixedly connected with the driving wheel saw beam above, two synchronous rotation, the driven wheel and a saw blade tensioning position. Rotary motion by the main motor, belt pulley, worm by two speed drive for transfer to the driving wheel, driving wheel, saw blade driven by the driven wheel to achieve, saw blade speed is three (for sawing machines vary, some by adjusting the frequency converter speed regulation to realize the saw belt velocity).The saw blade guide device： Installed in the guide saw beam plate consists of left, right guiding arm and the guide head, left, right guiding arm can move along the dovetail (or the right guiding arm is fixed on the upright post cover), adjust the distance between the two guide arm than the size of the workpiece width about 40mm. The guide device is used to change the blade installation angle, the blade and table vertically, in order to ensure the accuracy of cutting, saw blade vibration is reduced, on the left and right guide arms are respectively provided with a set of guide wheels (rolling bearing) guide block and wear-resisting, guide blade back also wear-resistant alloy.Gripper mechanism： Right jaw is fixed on the bed, the clamping screw rod through hydraulic clamping cylinder bore, the left jaw to move along a guide rail connected by screw around, connection when left vice from the workpiece in 10-30MM. Hand control panel clamp or clamp pine by clamp, the clamp or loosen workpieces.Tensioning device： The tensioning device is composed of a slide seat, skateboard, wire rod, when the saw blade tension, torque wrench clockwise rotation tensioning saw blade, in the work of the state. Such as sawing machine in long time shutdown, torque wrench counterclockwise rotation of blade loosen, loosen the blade can be replaced after the new saw blade.Work： Hydraulic drive system consists of pump, valve, oil cylinder, oil tank, pipeline element and auxiliary hydraulic circuit components, completed the saw beam lifting in the electrical control, workpiece clamping. Stepless speed regulating valve can be implemented through the feed speed, the different material workpiece sawing need. The control circuit of electric control system of the electrical box, control box, junction box, a travel switch, an electromagnet etc., used to control the rotary, saw blade saw lifting beam, workpiece clamping, which according to certain procedures to achieve the normal cutting cycle. Lubrication system before driving to positions according to the machine lubrication (wire brush shaft, worm gear box, a driving bearing seat, the worm bearing, lifting cylinder shaft, sliding surface activity vise clamping screw rod) for refueling. The worm, worm and worm gear box 30, oil bath lubrication, injected by the upper part of the oil hole is worm gear box, box face with fairy oil standard, when the saw beam at the lowest position, the oil level should be located between the upper, lower oil standard. After a month trial should be oil, after every 3 to 6 months the oil 1 times, the worm wheel is arranged at the lower part of the oil drain plug. Blade drive installed in the gear box of the motor through a belt pulley, V-belt drive the worm and worm gear worm gear box, drive the active wheel rotation, and then drive the saw blade in the active and passive wheel rim around the cutting of rotary motion. The hydraulic system of saw blade feed movement consists of lifting hydraulic cylinder and speed control valve, control the saw beam down feed to control the speed of saw blade (stepless) movement. Saw blade chip brush to rotate in place, and with the saw blade saw the direction of rotation, and a cooling pump for cooling liquid cleaning, cleaning out scraps sawtooth. The cooling fluid on the right side cutting coolant tank base, driven by the water pump for the cooling liquid. By close (stop) button, clockwise rotation, the pump motor, gear pump, oil into the pipeline through the filter, adjusting the overflow valve and the system working pressure up to requirements. Whereas the button is pressed inwards, all motors stop working. Workpiece clamping press clamp button, solenoid valve, hydraulic oil into the left on the right clamp cylinder, hydraulic oil return tank, a left pliers to clamp workpiece. The saw beam down according to work by clamp, hydraulic oil through the electromagnetic valve into the lift cylinder rod chamber; rodless cavity hydraulic oil through the electromagnetic valve, a one-way control valve back to tank. The saw beam quickly drop by drop button, hydraulic through electromagnetic valve, oil into the lift cylinder rod chamber, without a rod cavity oil through the electromagnetic valve oil return tank. The saw beam to rise in the ascending button, the hydraulic oil into the lifting oil cylinder through the electromagnetic valve cavity without rod; a rod cavity oil passes through the electromagnetic valve oil return tank. Loosen clamp workpiece by loose button, the hydraulic oil into the clamping cylinder right through the electromagnetic valve; the hydraulic oil to electromagnetic valve back to tank, left jaw movement to the left work unclamp.The NC reconstruction of a common band sawing machine Sawing blanking length is achieved by adjusting gauge 14 and return to the relative position of the position switch, feeding quantity by the counter, each action is completed by a position switch detection. The sawing speed is controlled by the pressure regulating valve to adjust the supply pressure. Logical relationships between action by relay, driven by the power cylinder to complete, is controlled by the electromagnetic valve complete. For ordinary band sawing machine, due to changes in pressure, hydraulic oil temperature change and the lag of electromagnetic valve and relay are influencing sawing feeding precision, so the cutting precision, consistency batch feeding is not good. In addition, changes in the ordinary band saw cutting length, because of the need to adjust the feeding length scale, the operation is relatively cumbersome. Because of the differences of sawing materials, the best performance of saw blade, saw blade speed and sawing speed automatic adjustment. For example, when the blade bending reaches a certain valve system value, system will reduce speed adaptive or close the feed. It requires great changes, the original common band sawing machine foundation such as: change the original hydraulic unit, increasing blade bending monitor. Assembling a grating ruler position measurement in the original common sawing machine, liquid pressure system. Control system software function design, including bin, storage management and retrieval, saw a classification management, saw blade bending monitoring, material pressing, blade speed, sawing feed speed adaptive control. In order to meet does not change the original hydraulic system requirements, system to increase the ordinary solenoid valve position control module based on. Analog input and output module of the system, the saw cutting process monitoring has general significance, such as: sawing machine saw blade deformation as adding feedback, can be adaptively adjusts the sawing speed. Increase servo valve, on sawing process control of speed and position optimization can be. System management function to the material and the workpiece management more convenient. The Chinese interface and real-time graphical display, make the operation more friendly, more intuitive. Since the system uses standard PC, make the network management more convenient sawing.Control system： Closed loop position servo control system is relatively easy. Ordinary solenoid valve is only pass, broken two states, and has electromagnetic mechanical hysteresis. The temperature and pressure of hydraulic oil affect positioning feeding table, so the traditional control theory is difficult to deal with. In order to reach the target position closed before feeding cylinder hydraulic feed, the feeding cylinder is stopped just in the target location, is the key to the problem.Module adopts sampling interpolation and foresee the position control system combining control servo position (specific control omitted). While the ordinary electromagnetic valve cylinder position control module uses learning, preview control, through the system experience value and the current state, decided to close the feeding cylinder position, make the feeding cylinder just to reach the target position stop. Because the electromagnetic mechanical lag and inertia, pass through off to control feeding sliding 0.1mm almost impossible. In order to guarantee the minimum length of feeding and feeding precision, rear caliper feed slide back into the LK position, and then move forward to the predicted location of LT closed feeding electromagnetic valve. When the feeding cylinder motion stops after clamp. After the clamping in place before clamp release, front clamp release in place to start feeding. Feeding in place before the clamp. Before clamping in place after the clamp release. After the clamp pine in place began to retreat, to prepare for the next feed.
