 Product Introduction

1.The main components of the equipment

The high-speed metal circular sawing machine is mainly composed of the machine bed, the power head part, the feed system, the automatic feeding device, the clamping device, the distributing device, the hydraulic system, the electrical system, the spray cooling system, the automatic lubrication system, and the chain plate chip conveyor. , Cutting fluid cooling device, saw blade cleaning device, etc.

2.1. Machine base

It is welded by 16Mn super thick plates. Since the strength of steel is 3 times higher than that of cast iron, and the rigidity is 2.5 times higher than that of cast iron, the welded structure box can ensure greater rigidity, and has a compact structure and high strength. Also the appearance is beautiful.

2.2. Saw head
1) The saw head is mainly composed of gear box, pulleys, variable frequency motor, magnetic powder brake, screw guide rail and AC servo motor, etc.
2) The gearbox is cast with high-quality and high-strength ductile iron. The gears, ground and formed with high precision, are multi-stage transmission design of hard-toothed helical gears, having high precision and stable transmission. The magnetic powder brake and the unique gear backlash elimination mechanism can realize one-way zero gap transmission, greatly improves the service life of the saw blade. The bearings of the gearbox adopt high-precision bearings from NSK, IKO and other brands. The gearbox runs smoothly and has high transmission efficiency, which is the prerequisite for high-precision cutting.
3) Using frequency converter + frequency conversion motor to drive gearbox to realize stepless speed change of saw head spindle.
4) In order to reduce the inertia of the saw head to achieve the purpose of high-speed cutting, the saw head adopts the horizontal feeding method. Using high-rigidity and high-precision roller linear guide, using high-power AC servo motor to directly drive the grinding-grade ball screw for reciprocating motion, it has high precision and good rigidity.

2.3. Feeding system

The high-precision ball screw cutter power head is driven by a servo motor to perform a flat-cutting powerful feed, and the clamped work-piece is cut off with high precision and speed. This method is the current international advanced high-speed circular sawing machine feed and sawing method, which can more effectively ensure the stability, reliability and continuity of the sawing process.

2.4. Using GFC (Gripper Feed Carriage) feeding mechanism for feeding

It is guided by double guide rods with strong bearing capacity, and adopts high-power AC servo motor to directly drive the grinding-grade ball screw for linear reciprocating motion, with good rigidity and high precision.

The clamping mechanism is powered by a hydraulic cylinder, with sufficient clamping and high clamping accuracy.

The clamp of the GFC feeding mechanism can float up and down during the front and rear feeding process, which will not cause scraping interference between the material and the clamp, and prolong the service life of the clamp.

2.5. Clamping device

The main clamp is fixed on the bed and consists of a set of horizontal and a set of vertical clamps installed on the clamp base. It can provide horizontal and vertical clamping force to the material during the cutting process. The clamping power is provided by the hydraulic cylinder, and the two groups of clamping can act independently. Among them, the front and rear two sets of devices can be clamped and loosened at the same time, which more effectively ensures the reliability of clamping and the stability of the sawing process.

2.6. Hydraulic system

The functions of the hydraulic system include material lifting, material clamping, etc. For the convenience of maintenance, it is an external independent station using integrated installation. The structure is compact, safe and reliable.The clamping vises are equipped with pressure switches, and the next step will be taken when the pressure reaches the set value.
