IB/T 9931.2~1999
Horizontal bow sawing machine is a grass-fed series, suitable for single or batch production in the road manufacturing industries such as mountaineering, stone blasting, machinery, * vehicles, bridges, agricultural machinery, etc. It is mainly used for sawing ferrous metal materials, square materials, profile materials and pipe materials. The machine tool transmission system has a certain variable range. The machine tool has a stepless adjustable hydraulic feed system, which can realize constant pressure or constant feed. The machine can make right-angle sawing at 90 degrees to the material axis, and can also make bevel sawing at angles not 90 degrees to the material axis. When the workpiece size is small, it can also be made into beam sawing. The machine tool standard should meet the requirements of 9931.3 of Taiwan R Hall The machine tool is a V-level precision machine tool as specified in IB/T No. 71. The saw bow of the machine tool moves along the guide rail of its supporting member, and the supporting member swings and feeds along the supporting axis within a certain angle range with the horizontal direction.
4.2 Jinchen type sawing machinebzxZ.net
The machine has the same purpose and performance as the corresponding basic system (except for the bevel sawing function), and has an automatic operation cycle, which is more suitable for mass production
In addition to the structural characteristics of the corresponding series, the machine tool also has: u) automatic loading and unloading device
b) Automatic material filling device
Automatic fixed length device;
d) Automatic counting device;
CNC device can be installed as needed.
4.3 Vertical and horizontal bow sawing machine
Vertical horizontal bow sawing machine is a basic series. The machine tool has the same purpose and performance as the horizontal bow sawing machine, with good rigidity and is suitable for sawing large-sized materials. The machine tool's height meets the requirements of relevant standards. The saw of the machine tool is supported by a guide rail that moves horizontally, and the guide member moves vertically along the guide rail of the column. 4.4 Automatic column horizontal bow sawing machine | |tt||The machine has the same purpose and performance as the induction series (it is possible to have an angle sawing function). It should also be equipped with: automatic feeding, unloading and weighing;
b) Automatic material clamping device:
Moving fixed length device;
Mounting counting device:
It can be equipped with CNC equipment according to needs.
