How to operate the sawing machine —— Inspection method for correct operation of the sawing machine

Before maintaining and operating the band saw machine, the following items should be checked regularly. Next, I will tell you how to operate the sawing machine correctly, hoping to help you!

1, check the oil gauge position of the gear box and hydraulic box of the sawing machine;

2. Check the chip removal height of the steel brush, so that the steel brush just touches the bottom of the sawtooth. It should not be higher than the bottom of sawtooth, which will cause excessive wear of saw band or steel brush;

3. Check the position of the chip cleaning brush of the sawing machine, keep the tooth gap and iron filings clear, and adjust or replace the chip cleaning brush when necessary;

4, check whether the sawing machine cooling water altimeter needs to be added;

5. Check whether the saw belt of the sawing machine is in the correct position of the driving wheel, the driven wheel and the tungsten steel guide vane;

6, check the sawing machine tungsten steel oil pressure gauge pressure;

7, check the sawing machine saw belt tension adjustment valve;

8. Check the tension belt of the gear box of the sawing machine;

9. Before installing a new saw band, remove the iron filings from the flanges of the driving wheel and driven wheel of the sawing machine (iron filings may accumulate).

Mechanical classification

electric/power saw

The circular saw belt is tensioned on two saw wheels, and the saw wheels drive the saw belt to cut. Band saws are mainly vertical and horizontal. The saw frame of the vertical band saw machine is vertically arranged, and the workpiece moves when cutting, which is used to cut the curve outline of the sheet metal and the molded parts. Saw belts can also be replaced by file chains or abrasive belts for file dressing or polishing. The saw frame of the horizontal band sawing machine is horizontally or obliquely arranged, and it is fed in the vertical direction or in the direction of swinging around a fulcrum, and the band is generally twisted by 40? To keep the serrations perpendicular to the workpiece.

Horizontal band sawing machine is divided into scissors type, double column type and single column type. According to the use situation, it can be divided into manual (economical manual feeding and manual cutting) and automatic; According to the automation program using the controller, it can be divided into manual (semi-automatic manual feeding) and full automatic (automatic feeding and automatic cutting).

knee bolter

Circular saws, also known as circular saws, are divided into full-automatic and semi-automatic types. The circular saw blade performs rotary cutting motion and simultaneously performs feeding motion together with the saw box (see figure). Circular saw machine can be divided into horizontal (horizontal feed), vertical (vertical feed) and pendulum (swinging feed around a point) according to the feed direction of saw blade.

In addition, there are all kinds of special circular saws, such as shaking table sawing machine for cutting large casting risers; Combined sawing and drilling machine tool.

bow saw

The saw bow with the saw blade moves back and forth, and the saw frame swings around a little. The machine tool has simple structure and small volume, but its efficiency is low. There are two kinds of motion trajectories of the saw blade of the bow saw: straight line and circular arc.

When the circular arc moves, the saw bow swings around a small angle, so that each saw tooth has a large cutting amount, easy chip removal and high efficiency. This method is adopted by most new bow sawing machines.
