Beam Drilling Machine

The combination production line consists of XT-SWZ1250 drilling line and XT-YJC1250 Band Saw, two pairs of infeed in and outfeed conveyors ,and one CNC control device and two side conveyors, along with electrical system, hydraulic system, air cooling and lubrication.

The combination line adopts Z form arrangement that the drilling line and the band saw are installed in parallel and connected by transverse conveyor. Each of the two infeed conveyors equips a NC feeder dolly with servo motor on the datum side and side push device to push the workpiece to the datum side; the drilling line equips an automatic transverse conveyor to upload workpiece; the outfeed conveyor equips roller to move the workpiece out of the process zone and to the transverse conveyor.

In the working process, the personal should lift the workpiece to the automatic transverse conveyor, after the workpiece is uploaded to the infeed conveyor from the transverse conveyor, the side push moves the workpiece to to the datum side, and the dolly moves the workpiece to the processing zone to drill, after the drilling, the roller moves the workpiece to the outfeed conveyor, the transverse conveyor which connects drilling line and band saw moves the workpiece from the outfeed of the drilling line to the infeed of the band saw to cut the workpiece, after the cutting the workpiece is downloaded to the outfeed, and the transverse conveyor of the band saw moves the workpiece out of the processing zone.

The process sequence is from drilling to cutting, the long workpiece which is meant to process into several pieces can be drilled integrally and then cut in to pieces. The transverse conveyor between two lines in Z form arrangement can can adjust the process speed. The Z form arrange let these two lines work both together and separately, when one of them is in maintaining the another line can work independently.
