Equipment composition profile:

The equipment is composed of a sawing tape saw, hydraulic system, a saw tape cooling lubricating device, a chip conveying device, a safety shield, an electrical and an automation control system, and the like.

3.1 Sawed Saw Machine

● The belt saw is composed of a base, a sawing, a saw wheel, a transmission portion, a feed system, a bed part, a tape tensioning mechanism, an arm and left and right guide wheel mechanisms.

● Base and sawing portion: The blade is welded and treated with a steel sheet and is treated back to the fire. Surface sandblasting treatment, precision machining, good structure design, beautiful appearance;

● Saw wheel section: It is made of imported hard aluminum plate (7075-T61) and is finished, and the rim is passed through a bag vulcanized rubber. It can reduce operation noise; the saw wheel is running with a smoothly equilibrium correction, turning smoothly and long life.

● Transmission section: Driven by the Datong Variable Motor, by the synchronous pulley structure, the power is transmitted to the active pulley, and the saw belt is high-speed operation. The transmission efficiency is high and stable. The speed is 500-2000m / min, the speed range is large, and can be adapted to the saw cut of a variety of grades of aluminum alloy;

● Feed system: The feed system is driven by hydraulic pressure, and the feed speed is 0-2 m / min, stepless speed regulation.

● Sawdow rises: use double tilt column and linear slide structure as a lifting orbit, two-stranded guidance on the saw tape drive side, and the saw band tightening side adopts a single-strand guide. The linear slide is HGW45 / HGW35.

● Bed section: The bed table is made of HT300. In addition to providing sufficient support for the material saw, there is also a set of hydraulic clamps for a set of fixed positions, thereby defining the sawing material stroke to ensure that the sawing is stable.

● Saw tensioning mechanism: Saw tensioning mechanism is driven by hydraulic driving, using the electrical connection pressure gauge to display tension value and have a broken band protection;

● Sawband guiding device: Use the left and right group of sawband guide. Each group of guide wheel attached 4 adjustable guide rollers, the wheel material is made of alloy structural steel (15CrMo), surface carburized quenching, hardness 50-55 hrc, is well wear-resistant, and the strip section is treated with grinding, ensuring the guide accuracy In addition, there is a tungsten steel ring in the saw back, which can provide sufficient support to the saw tape during sawing, and can reduce the efficacy of the saw tape vibration. The guide means is mounted on the fixed arm and the moving arm, designed to adjust the structure, the fixed army is designed as an integral, mounted on the slider, so that the 2 columns are connected under the base and the fixed army arm, form stable Frame structure to provide sufficient support to ensure that the sawing is frequently declining and can reduce vibration.
