Introduction to the material properties of straight knives

Most of the straight knives on the market are forged with carbide as the raw material. Cemented carbide, also known as tungsten steel, is made of high-quality tungsten carbide + cobalt powder mixed by formula ratio and sintered by pressing, with high hardness, high strength, high wear resistance, and high modulus of elasticity, belonging to the powder metallurgy industry. Cemented carbide is the "teeth" of modern industry, and cemented carbide tools play a fundamental role in promoting the development of the manufacturing industry.

Precautions when using straight tools

Before introducing the next relevant content, it should be especially reminded that the user should do a good job of protection before the blade installation to avoid unnecessary personal and property safety losses caused by falling blades.

straight knife blade installation

Before installing the blade, please carefully clean the dust, chips, and other debris on the rotating bearing mounting surface of the machine to keep the bearing mounting surface and the machine clean. In addition, before blade installation, please use your right index finger to carefully hook the blade and let the blade hover, then tap the blade body with a wooden hammer and listen to the sound from the blade body. Experience has shown that the blade body of the muffled sound has often been damaged by external impact cracks, damage, such blades should be immediately prohibited from use. Carefully check the quality of the machine and the blade before installing the blade to the machine, the correct installation steps are.

l Place the blade carefully and smoothly on the mounting surface of the bearing, and turn the bearing by hand to make it and the center of the blade automatically find the center alignment.

l Install the knife press block on the blade and align the bolt holes with the bolt holes on the bearing.

l Install the hexagonal bolt and fasten the screw with the hexagonal wrench to mount the blade firmly on the bearing.

l After the blade is installed, there should be no loosening and skewing.

Safety protection

After the installation of the blade, before starting the machine must be installed on the machine safety guards and other protective devices in place and play a real protective role, such as cutting foot machine on the blade studio surrounded by safety stopper, steel plate, rubber, and other protective layers. In addition, the machine's operating speed should be taken into account, and before official use, the machine needs to be test run to ensure that the accessories are solid.

Different machines have different running speed requirements, such as the working speed of the foot-cutting machine should be limited to 4500 rpm or less. The specific operation should be strictly in accordance with the instructions for the use of the machine to operate, it is strictly prohibited to exceed the speed limit running the cut machine!

After the blade is installed, to run empty for 5 minutes, and carefully observe and listen to the machine's operating conditions, absolutely no obvious loosening, vibration, and other abnormal sound phenomena exist. If abnormal phenomena occur, should immediately stop and ask professional maintenance personnel to check the cause of the fault, to confirm that the fault is completely eliminated before use. In the cutting process, please advance the items to be cut at an even speed, do not advance too rapidly and quickly. When the object and the blade have a violent collision, it will lead to blade damage and even serious safety accidents.
