Embodiment Construction

[0023] In the first embodiment, by total weight: glass fiber cloth is 20-35wt%, carbon fiber is 2-10wt%, epoxy resin is 30-60wt%, others are conventional curing agent, filler, diluent, infiltration agent etc. The specific steps are as follows: Cut the carbon fiber and glass fiber cloth into shape according to the required size, prepare several, first put one into the mold that is cleaned and coated with a release agent, and the wetting agent used for the mold is alkali such as hydrogen Sodium oxide, sodium carbonate, potassium hydroxide, etc. Then put the embedded parts (metal parts such as knife seat or lower knife seat and center positioning ring (shaft sleeve)) at the predetermined position; stir and mix epoxy resin, quartz sand and other fillers in another container. Conventional accelerator diluent ( Such as propylene oxide), etc., mix part of the mixture with curing agent such as amines of m-phenylenediamine and pour it into the mold to level it. Repeat the operations ...

Abstract

A combined saw blade is composed of saw blade matrix made of fibre reinforced thermosetting or reinforced thermoplastic plastics, cutter heads, and cutter seats consisting upper and lower units. Its advantages are high weight, exchangeable cutter, and no rust of saw blade matrix.

Description

technical field [0001] The invention relates to a saw blade, in particular to a composite saw blade, which can be used on a cutting machine to cut various materials, such as cutting stone, metal, plastic and the like. technical background [0002] There are many applications related to saw blades, such as CN2410098, 2168672, 2419025, 2400253, 2477342, 2468703, 2267146, etc., the contents of which are incorporated herein by reference. Saw blades generally comprise a disc-shaped metal substrate and teeth, with or without diamond coating and / or diamond bonded layers. In some applications, the sawtooth includes a cutter head and a cutter seat, and various methods are used to connect the cutter head to the saw blade substrate, such as CN2168672. However, a saw blade related to plastic has not been found; only CN2410098 discloses a saw blade for cutting wood, wherein a plastic layer is used to cover the metal saw blade substrate, and the purpose is only to...
