The main structure of the machine tool:
The sawing machine is composed of bed bucket, saw frame, column, main transmission device, saw belt guide device, saw belt tensioning device, hydraulic system, cooling system, clamping device and other auxiliary parts.
1. Bed bucket:
The bed bucket is a plate weldment with a built-in coolant pool. The machine is mounted on the foot and foundation to bear the weight of the machine itself and the weight of the workpiece.
2. Saw frame:
Sawing frame is the basis of sawing machine, which is welded with high quality steel plate, and has sufficient rigidity after aging treatment after welding.
3. Column:
150 The main column, the saw frame and the bed bucket are connected by the column to make the up and down movement, which is the need to ensure the accuracy of the work; The column is equipped with a column sleeve as a guide mechanism for lifting movement.
4. Main transmission device:
The main transmission adopts worm gear transmission mode, which is composed of the main motor, worm gear box and saw wheel, mainly used to transfer torque, drive the band saw blade rotation, in order to achieve cutting movement, through the belt on the belt pulley, can be transformed to achieve three cutting speed, to apply to the cutting requirements of different materials of the workpiece.
5, sawing machine guide device:
Saw belt guide mechanism: composed of beam, guide arm, guide head, bearing, alloy base and tungsten steel alloy sheet, the band saw blade through the bearing of the guide head to twist the band saw blade and the work surface to maintain vertical; The alloy seat and tungsten steel alloy plate are tightly attached to the back and side of the band saw blade to reduce the friction of the band saw blade to a minimum; The guide arm is locked on the beam, and when cutting the workpiece of different widths, the guide arm can be moved to achieve the shortest distance between the left and right guide heads, so that the flexible band saw blade enhances the rigidity and obtains the appropriate flexibility.
6. Saw belt tensioning device:
Saw belt tension mechanism: composed of driven wheel, tension seat, hydraulic cylinder and slider, by manually rotating the screw to move the slider to drive the saw wheel to achieve the tension of the band saw blade, so that a certain pressure is formed between the band saw blade and the saw wheel rim, generating enough friction to drive the band saw blade for rotating motion.
7, cooling device and cleaning:
Cooling is indispensable in sawing, can play a cooling, lubrication role, play a role in protecting the band saw blade. The cleaning device is to take away the chip accumulation caused by the sawdust and extend the service life of the band saw.
8, clamping device structure:
Table clamping device: the working table is smooth and flat, and the workpiece must be placed on the working table for cutting, which is one of the main components to ensure the cutting accuracy; A set of clamping vise is installed on the workbench, and the fixed vise is installed on the right end face of the workbench. The active vise is promoted by the oil cylinder and moves left and right in the workbench chute to clamp the workpiece and ensure that the workpiece is fixed on the workbench during the cutting process.
