The risks in the machinery industry need to be controlled and appropriate processes and methods, and establish and implement a perfect system. The woodworking multi-blade saw blade is a common processing tool in the wood industry. Because of its high-speed rotation, it often harms people and causes losses to the enterprise due to the improper operation of workers. So let's learn how to use the woodworking multi-blade saw blade more safely!
First of all, you need to know about the sawtooth. The sawtooth is composed of multiple teeth. The sawtooth is sharp and does not lack the number of teeth. Straightened teeth are the basic requirements for use, and continuous missing teeth are not allowed when missing teeth. In addition, when the saw board has cracks in the practical process, it should be stopped. In addition, the general manufacturer of the serrated end will block the crack hole, and it cannot be used if there is no crack hole. In particular, it cannot be used for multiple saws.
We can start the machine only after the sawtooth meets the above conditions. Before formally cutting wood into sawtooth, it is necessary to ensure that the rotation speed of sawtooth is normal. In addition, the wood shall not be shaken. If there are hardwood knots, the material needs to be supplied at a constant speed. The feeding system of the multi-plate saw is constant speed feeding, which can be avoided.
When the temperature of the saw tooth is too high, it needs to be cooled with cold water. When the rotation speed of the saw tooth with a diameter of more than 600mm reaches 2000 rpm, it needs to be cooled with water spray. After the operation, press the emergency stop button to turn off the main switch.
The multi-blade saw machine has simple operation, high processing efficiency, and the discharge standard is more and more popular with wood processing plants. However, the phenomenon of burning deformation often occurs in the daily use of woodworking multi-blade saw blades, especially in some new processing plants. Burning chips will not only increase the use cost of sawtooth, but also directly reduce the productivity by frequent replacement of sawtooth.
Cemented carbide is welded on the substrate of woodworking multi-blade saw blade, which is collectively referred to as scraper. The scraper is generally divided into internal scraper and external scraper. The internal scraper is used for hardwood cutting, the external scraper is used for wet wood cutting, and the scraper is used for edging or edging blade, but it cannot be generalized. Take Xiaolin's multi-piece serrations as an example. Generally, the number of design blades below 10 inches is 2-4, but the number of design blades above 12 inches is 4-8, and the number of internal and external blades is half. The trend of multi-piece serrations with scrapers is that foreign companies have invented multi-piece serrations with scrapers very early.
When cutting wet wood or hardwood, in order to obtain better cutting effect, it is necessary to reduce the porcelain pieces of sawdust paste, increase the chip removal capacity of the machine, reduce the number of times, and improve the durability. However, the scraper of the multi-blade saw with scraper is difficult to grind, and the general equipment cannot grind, and the price is relatively high.
In addition, when working by hand instead of using multiple saws, if the saw path is offset, it needs to be adjusted slowly. Pay attention not to bend the sawtooth hard to prevent danger. In the machine with protruding teeth, the operator and relevant personnel cannot operate in the direction of centrifugal force rotating towards the teeth, and the arm cannot cross the teeth for operation.
