Column horizontal band sawing machine is mainly used to cut all kinds of ferrous and non-ferrous metals. It has the advantages of narrow cutting edge, material saving, energy saving, high cutting precision, easy operation and high production efficiency.

The machine tool is mainly composed of a host(Including: bed, main drive system, saw frame, working table and clamping mechanism, belt break protection device, knife setting device, etc.), a feeding device, a feeding device, a discharging device, a hydraulic system, an electrical system, a cooling and lubrication system, a pneumatic system, etc.

Working principle

After the PLC is connected to the power supply and the hydraulic pressure is started, set the required material length, material length correction, product length setting, product length correction and other parameters in the text display under the display setting flag. Turn the working mode manual/automatic selection knob SA10 automatically. Press the automatic start/stop button SB6, after starting automatic, the sawing machine will perform automatic cycle work.

The feeding trolley first returns to the feeding roller station No. 4 → detects the presence or absence of material at each station → the station No. 3 has a material → the cart moves back to the station No. 3 → the same material cylinder and the same material → the feeding car lifts up the material → feeding The trolley feeds the workpiece into the feed roller (two) → the trolley descends and falls → the feeding vise moves backward, clamps, and feeds (repeated twice to make the feed head and the front jaw of the feeding vise flat) → the feeding vise moves back to Feeding head setting position → feeding vise to clamp the material in advance → working vise to clamp the workpiece → sawing operation, water pump working, saw frame enters the feeding and cutting state → sawing material head is completed, the saw frame rises → feeding vise Loosen the workpiece and back to the set value of the finished length →feeding vise clamping, working vise loosening→feeding vise feeding→pushing the material head into the material head/material tail slide (the head and tail material output flap is controlled by manual intervention)→working vise clamping workpiece→ the saw wheel is running, the water pump is working, and the saw frame enters the state of feeding and sawing → the finished sawing is completed, the saw frame rises → the feeding vise releases the workpiece and moves back to the set length of the finished product → feeding vise clamping, working vise Loosen→feed vise feed→put the finished workpiece into the discharge and push area through the motorized discharge roller, the push cylinder pushes the workpiece into the feed frame... until the first group is sawed, (the sensor sends a signal) the second Group workpieces automatically enter the sawing cycle...

Using the control system with NA200PLC as the core, it realizes the automation and semi-automatic control of feeding, sawing, discharging and other processes, safe and reliable.
