The production process of saw blades is not as simple as you think. With the development of this tool and the continuous improvement of cutting materials, the requirements for the processing technology and manufacturing technology of saw blades are increasing, especially for new tools such as electric saw blades and pneumatic saw blades. The specific manufacturing requirements are more demanding. What are the main processing and manufacturing steps of a saw blade? For you to organize the nine important steps in the processing of saw blades: teeth opening, cutting, welding, dressing welding, toothed initial grinding, band saw trimming, raking or material, sharp tooth shape, grinding saw Back, etc., the specific introduction is as follows:
A. Open the tooth Before the saw blade is opened, the shape check of the saw blade should be done first.
B. Cut off According to the length and length of the saw blade required by the saw machine, the line is cut off and strives to be vertical. Truncated flat steel hoes and hoes are generally used, and it is best to use a truncator to cut off.
C. Welding At present, the welding of saw blades is mostly made by silver welding.
D. Initially renovating the weld. After the new saw blade is welded, when trimming, a piece of sleeper with a curved surface can be placed on the platform, and the saw joint is placed on the sleeper.
E. Tooth shape initial grinding The new saw blade uses a serrated machine to open the serrations. There are many burrs on the edges. To prevent the saw blade from being trimmed, the tooth shape should be initially ground.
F. Trimming of the saw blade The comprehensive inspection and dressing of the saw blade is carried out after the joint is trimmed. It includes horizontal trimming and proper tensioning, which is an important process.
G. The new saw blade is to be plucked or plucked after the initial shape of the tooth profile. The purpose is to widen the tooth tip and form a “saw road” so that the entire saw blade can pass through the cut. Wood, reducing frictional resistance.
H. Sharpening of the tooth tip The saw blade before the hopper is formed to form a uniform pitch.
J. Grinding saw back After the new saw blade is finished according to the above sequence, the edge burr of the saw back is also polished.
