Mechanical Introduction of the Billet Cutting Saw machine

(1) The Saw Tooling Box of the circular Cut off saw

The saw box of the metal saw is fabricated using Q345-B material and undergoes aging treatment to eliminate internal stress. The four-row bearing hole processing technology is optimized, and the combined boring bar ensures precise hole positioning and dimensional accuracy when closing the box with the cover.

The gear features a no-backlash transmission structure, made of high-quality steel that has been quenched and ground to achieve level 6 accuracy. The input/output shafts and intermediate shafts are manufactured from high-quality hardened steel.

Precision bearings are used in the saw box, with INA needle roller bearings selected for specific applications and NSK or FAG products chosen for other bearings. The belt groove position remains fixed, while an unloading structure at the I-axis prevents bending or deformation, facilitating convenient loading/unloading operations as well as ensuring connection with the main motor.

Oil cooling lubrication is employed for both the main shaft and gear to maintain good rigidity, low temperature rise, and high precision within the entire rotating system. Furthermore, incorporating a no-backlash transmission structure inside the saw box reduces impact on teeth and support components, thereby enhancing service life while minimizing noise levels.

(2) The guide mechanism of the Circular saw for billet cutting

The guiding mechanism is composed of a drag plate, a pair of pre-tightened roller linear guide rail and an additional pressure unit. The pressure unit includes an oil cylinder, a wedge-shaped block and a guide rail.

When the gear box fast forward into the working time, the cylinder pushes the block to fix the flat guide rail tightly, so as to effectively transfer the cutting force acting on the saw blade to the frame, reduce the tipping moment generated on the main rail, and improve the working life of the guide mechanism;

During non-cutting working hours, the cylinder rod is withdrawn to reduce the load on the feed mechanism. The additional slide rail is at the same level as the lowest position, and can accommodate the largest diameter of the saw blade, on this basis, better transfer the cutting force to the frame to protect the guide rail

(3) The Main Transmission System of the saw machine

The Metal cutting saw machine is equipped with a powerful variable frequency motor. The spindle motor drives the spindle and saw blade to turn at high speed by belt and gear

(4)Slide feed device

The servo motor of the industrial saw is slowed down by the precision reducer and connected with the ball screw to drive the saw box to move forward and backward along the guide rail of the bed.

(5) The Machine Base of the metal saw

The bed base of the metal saw is the base component of the machine and is of thick plate welded construction and filled with concrete to increase rigidity. After aging treatment, it has high stability and is not easy to deform. The bed is equipped with two rolling guides to guide the movement of the saw box, thus providing good stability.

(6) The Saw blade guide/shock absorber

The cold cutting machine is equipped with three sets of guiding/damping devices, which are installed on both sides of the saw blade to ensure that there is no vibration when the blade enters and exits during sawing, and to prevent bending vibration during high-speed rotation. The friction plate is used as the liner.

(7) The Clamping Device

Each Circular saw blade is equipped with a set of clamps on both sides, including horizontal and vertical clamps and a clamp base for fastening the tube billet. These clamps are hydraulically fastened and also have an automatic separation function for quick exit of the saw blade, with a separation distance of 5mm.

(8) The Lift roller table at exit of the circular saw for cutting billet

At the discharge position near the edge of the saw, an adjustable height lifting roll of 140°V is provided and hydraulically controlled to ensure that the tube billet can pass through the clamping device without colliding with it.

(9) The Chip cleaning device for the circular saw for cutting steel

A micro-motor drives a brush to clean the sawtooth surface.

(10) The Chip Conveyor Chain (optional )

The chip is discharged from the sawing area through the magnetic structure

(11) The Fixed Measuring Device (optional)

The feeding trolley is installed on the base, and is driven by the servo reduction motor through the rack and pinion to move forward and backward on the base rail. The billet is clamped by the hydraulic clamping arm of the feeding trolley,In order to avoid the collision between the billet and the fixture when the car is fed, the base has the lifting function

(12) The Saw blade replacement device (Optional )

The saw blade replacement is placed next to the saw machine and consists of a cantilever hoist and electric hoist.
