The main components of the sawing machine are the bottom seat; the bed, the column; the saw beam and the transmission mechanism; the guiding device; the workpiece clamping; the tensioning device; the feeding frame; the hydraulic transmission system; the electrical control system; the lubrication and cooling system;

1. Base

The base is a box-shaped structure welded by steel plates. The bed and columns are fixed on it. There is a large space in the inner cavity of the base. The front left side is the electrical button control box, and the right side is the electrical switchboard box. The middle is welded by steel plate. The hydraulic oil tank is equipped with a hydraulic pump station and hydraulic pipelines. The right side is a cooling cutting fluid tank and a water pump. There are anchor bolt holes at the four corners of the bottom.

2. Bed

The bed is made of cast iron and fixed on the base. The column is composed of a large and small cylinder. The large circular column is used as a guide rail for the saw frame to support the up and down movement of the saw beam and to ensure accurate guidance. The small cylinder plays an auxiliary role. Ensure the normal cutting of the saw blade. In the middle is a clamping vise and a manual feeding mechanism. The front of the vise is connected with a worktable for receiving finished parts. The clamping device on the left is for clamping the screw rod to pass through the inner hole of the hydraulic clamping cylinder rod, turn the handwheel or press Button to move the left jaw to left and right.

3. Saw beam and transmission mechanism

It is made of thick steel plate by cutting, forming and welding. It has strong rigidity. The worm gear box is fixed on the right rear side. The worm gear in the box is fixedly connected with the driving wheel on the saw beam. The two rotate synchronously. The left side is the driven wheel and the saw blade. Tension position. The rotary motion of the saw blade is driven by the main motor, belt pulley, and worm gear through two-stage transmission to the driving wheel, and then the driving wheel and the saw blade drive the passive wheel to achieve the saw blade running speed in three gears.

4. Saw blade guide device

The guide device installed on the saw beam support plate is composed of left and right guide arms and guide heads. Both the left and right guide arms can move along the dovetail (or the right guide arm is fixed on the column sleeve) to adjust the distance ratio between the two guide arms. The workpiece size is about 40mm wide. The guide device is used to change the installation angle of the saw blade so that the saw blade is perpendicular to the worktable. In order to ensure the cutting accuracy of the saw blade and reduce vibration, a set of guide wheels (rolling bearings) and wear-resistant guide blocks are installed on the left and right guide arms. Guide block of wear-resistant alloy.

5. Clamping mechanism

The right vise is fixed on the bed, the clamping screw passes through the inner hole of the hydraulic clamping cylinder, and the left vise is connected by the screw to move left and right along the guide rail, and is connected when the left vise is 10-30 mm away from the workpiece. Press the clamp on the control panel to clamp or loosen the work piece.

6. Tensioning device

The tensioning device is composed of a sliding plate seat, a sliding plate, a screw rod, etc. When the saw blade is to be tightened, the saw blade can be tightened by rotating it in a clockwise direction with a torque wrench, and it is in working condition. If the sawing machine is stopped for a long time, turn the torque wrench counterclockwise to loosen the saw blade. After loosening the saw blade, replace the saw blade with a new one.
