What is the function of the saw card of the woodworking band saw machine?

The function of the saw blade automatic tensioning device of the woodworking sports car band saw machine is that when the woodworking band saw machine is sawing wood, heat is generated due to friction, or wood hardness is different, when sawdust is stuck on the edge of a joint or a saw wheel, the saw blade is automatically expanded and contracted, so that the tensioning force of the saw blade is kept balanced. If there is no automatic tensioning device, then the position of the upper saw wheel does not change at any time. At this moment, when the saw blade is elongated, the tensioning force will decrease. When it is light, the saw blade will swing, which will affect the quality of the saw blade. In serious cases, the saw blade will slip or fall off. When the saw blade shrinks, the tension increases, which will cause the saw blade to crack or break. Therefore, in order to solve the possibility of the above situation, band saw machines will have automatic saw blade tensioning device, which mainly plays a role in protecting the saw blade.

There is a device called saw card on the woodworking band saw machine. It is an important structure on the band saw. Its main function is to hold the saw blade so that the cutting part of the saw blade can keep linear motion when sawing wood. The saw blade is relatively thin and has small rigidity. If there is no saw card, the saw wheel will swing and damage the saw blade when running at high speed without controlling the saw blade.

Structure of saw card:

The saw card is generally made of two hard and wear-resistant wood boards, which are fixed on the machine base or lifting arm by bolts, and can be properly adjusted according to the width and thickness of the saw blade, so that the saw blade can smoothly cut wood without obvious gap. The saw card installed on the machine base is called the lower saw card, which is fixed when sawing. The upper saw card installed on the lifting arm of the saw card is called the upper saw card. When sawing wood, the height of the upper saw card can be adjusted at any time according to the height of the wood.
