    One. Main purpose and scope of application

    NST-5032 double-column horizontal band sawing machine learns the German brand PEHAPA double-column double-cylinder double-beam structure, combined with its professional 20 years of research and development experience, a new type of sawing machine specially developed for the mold steel cutting industry. And has obtained the national invention patent (patent number: ZL201510260342.1) scientific and reasonable structure, generous appearance, high cutting efficiency, long service life of the band saw blade, is ideal for large and medium-sized materials cutting equipment.

    Main features:

    1. Using hydraulic clamp structure, the workpiece enters the cutting position from the back of the sawing machine, and the clamp is used to fix the workpiece for sawing.

    2. The unique saw band guide clamping device is designed by itself to improve the working conditions of the saw band, extend the service life, and reduce noise to reduce environmental pollution.

    3. Double hydraulic cylinder design, combined with two large double columns to form a stable sawing structure.

    4. Centralized push button switch control panel

    two. main feature:

    1. The double-column and double-cylinder structure greatly prolongs the service life of the machine tool and the complete service life of the saw blade.

    2. Double hydraulic control sawing feed speed, stepless speed regulation, more stable during sawing.

    3. The linear speed of the saw blade adopts four-level speed regulation (26 41 55 79),

    4. Stable cutting and high precision.

    5. Hydraulic clamping is adopted for work clamping, which is convenient for operation.

    6. Feeding is manual feeding, without following rack.

    three. working environment

    1. The ambient temperature is higher than 0oC

    2. The relative humidity of the air is not more than 85% (equivalent humidity is 20 ± 5 oC)

Fives. Main mechanical structure

The company uses high-quality materials and precision machine tools for the critical parts of the machine tool, which are processed in strict accordance with the process specifications.

1. Transmission components

The worm gear is made of tin bronze material and is processed on a precision gear hobbing machine with a precision worm gear hob. After the worm is quenched, it is ground on a precision worm grinder, with a high surface finish and high precision. The box body adopts HT250 cast iron, with the special boring die to ensure the machining accuracy, and the worm gear has a long service life.

2. Upright

The hard chrome-plated surface is tightly ground and very wear-resistant. The guide sleeve is made of self-lubricating and wear-resistant material. No crawling phenomenon occurs during the work. The gap between the two is small, the rigidity is good, and the saw cut surface is perpendicular it is good.


3. Saw beam part

   The saw frame is welded with high-quality steel plate shock-absorbing structure and processed after aging treatment. The saw frame is mainly used to support the main transmission system, saw blade tensioning device, saw blade guide device and other components. This shock-absorbing structure is the first technology in the sawing machine industry. During the use of the sawing machine, the force of the two columns is greatly reduced, and the performance and service life of the sawing machine are doubled compared with similar sawing machines.

4. Hydraulic parts

The inner wall of the oil cylinder and the piston are plated with hard chrome, and the seal adopts a high-quality brand name, so there is no creeping leakage and high durability.

5. Electrical part

The wiring is neat, the structure is reasonable, and the heat dissipation is strong. The main electrical components are Chint products.
