The transmission mechanism and the outside of the saw blade are provided with protecting covers and are provided with a handle for a push-button switch. The utility model has the advantages of compact structure, small size, high efficiency, light weight and convenience for carrying.
Description
The utility model relates to the portable electric saw for woodworking of the thin flitch material of a kind of cuts sheet material that is used for, particularly bulk, belongs to timber machining tool class.
In modern furniture manufacturing and building decoration, use thin flitch material more and more, as glued board, fiberboard, laminating particieboard etc., traditional floor type electrically cutting tool, (as band saw, circular saw etc.) limit owing to itself and by the geometry of saw part and can not cut this type of material effectively, the thin flitch material of bulk can only be used the knife saw hand cut, and labour intensity is big, and production efficiency is low.
The purpose of this utility model is to provide a kind of compact conformation, and volume is little, and portable band is easy and simple to handle, and the efficient height is suitable for cutting the portable electric saw for woodworking that bulk approaches the flitch material.
The purpose of this utility model can reach by following measure: the transmission mechanism that the utility model has a cover to link to each other with motor, output at transmission mechanism is equipped with saw blade, guard shield is equipped with in transmission mechanism and saw blade outside, and saw blade one side is equipped with handle, and press button is housed on the handle.Above-mentioned motor, transmission mechanism, guard shield and handle all fix with supporting plate, and saw blade the place ahead has the bullport that the saw straight line is used.
Described transmission mechanism can be gear drive, Worm and worm-wheel gearing and chain wheel driving mechanism.
The utility model work engineering is as follows: the power of motor output drives the saw blade high speed rotating by power transmission shaft and carries out the material cutting after transmission mechanism slows down or commutates.During the sawmilling material, will be fixed by the saw part, and hold handle, the bullport in saw blade the place ahead is aimed at the straight line that will saw, and pinch press button, saw blade promptly begins to rotate.The hand push electric saw travels forward and can cut along line of cut.Release button switch, electric saw are stop motion.
The utlity model has following advantage:
This electric saw for woodworking can saw thickness at 4.5cm with the thin flitch material of bulks such as the glued board of interior virtually any size, plank, fiberboard, laminating particieboard, bakelite plate, plastic plate, poly (methyl methacrylate) plate.In the sheet material field, can replace handsaw substantially.
2. this electric saw for woodworking compact conformation, volume is little, and is in light weight, and weight has only 2.5～3.5kg.Therefore, the carpenter carries very convenient.
3. this electric saw for woodworking can adopt thin saw blade, so saw kerf is little, waste material not, and can significantly improve the fineness of cut surface.
4. this electric saw for woodworking cutting speed is manual 10～20 times, therefore can improve cutting efficiency greatly, and reduce labour intensity significantly.
5. this electric saw for woodworking handling safety, easy.
