Description
Technical Field
The utility model belongs to the technical field of cutting tool and specifically relates to a biplate combination saw bit is related to.
Background
The saw blade used for the cutting tool in the current market mainly comprises three types, namely a resin grinding wheel cutting blade, a diamond saw blade and a hard alloy saw blade. The resin abrasive wheel cutting piece is mainly used for cutting metal materials, but cannot be used for cutting cement and stone materials, the cutting loss is fast, the service life is short, and the application range of the resin abrasive wheel cutting piece is limited. The diamond saw blade can only be used for cutting non-metal materials such as wood, cement, stone and the like, but can not be used for cutting metal materials, thereby limiting the application range of the diamond saw blade. The hard alloy saw blade is widely applied to the industries of road construction, home decoration, machining and the like.
In super thick saw bit field, because saw bit body thickness is too thick, generally be greater than 5mm, even 7mm, the width of its sawtooth (tool bit) that matches will be greater than 7mm, can not weld completely when the too thick tool bit leads to the sawtooth to weld on the saw bit body, current saw bit welding generally adopts high frequency welding, and high frequency welding is not applicable to super thick saw bit, especially be so to the super thick saw bit that saw bit body thickness is greater than 5mm, want the complete welding to reach the intensity standard, just need prolong welding time, and overlength welding time can modify the carbonization to the tool bit, seriously influence tool bit life. And the use amount of the prior ultra-thick saw blade is small, so that the production cost of the saw blade is far higher than that of the conventional saw blade, therefore, the dual-blade combined saw blade is designed, the two conventional saw blades are combined into the ultra-thick saw blade on the premise of not increasing the number of saw teeth, the problem of tool bit welding is solved, and the production cost is reduced.
Disclosure of Invention
The utility model aims to solve the problem that to the shortcoming among the above-mentioned prior art, put forward improvement scheme or alternative, especially a biplate combination saw bit.
In order to solve the above problem, the utility model discloses a scheme as follows: a biplate combination saw bit, characterized by, it is made up of A saw bit and B saw bit; the tooth space of the A blade is equal to that of the B blade; the blade A and the blade B are both provided with mounting holes and positioning holes; when the A blade and the B blade are combined through the positioning holes, the sawteeth on the A blade and the sawteeth on the B blade are arranged by staggering 1/2 teeth.
Furthermore, according to the above design scheme, the double-piece combined saw blade is characterized in that the A piece saw blade and the B piece saw blade are respectively provided with an independent silencing line.
Further, according to the design scheme, the double-piece combined saw blade is characterized in that the thickness of the saw blade bodies of the A saw blade and the B saw blade is 3.5 mm; the width of the saw teeth on the A saw blade and the B saw blade is more than or equal to the thickness of the saw blade body.
Furthermore, according to the above design scheme, the double-piece combined saw blade is characterized in that the A piece of saw blade and the B piece of saw blade are respectively and uniformly provided with three expansion grooves.
Furthermore, according to the above design scheme, the double-piece combined saw blade is characterized in that the positioning holes are symmetrically arranged on two sides of the mounting hole.
Furthermore, according to above-mentioned design the biplate combination saw bit, its characterized in that, the amortization line is snakelike amortization line, and the both ends of amortization line are equipped with circular through-hole.
The technical effects of the utility model are as follows: this application has designed a biplate combination saw bit, makes up into super thick saw bit with two conventional saw bits under the prerequisite that does not increase sawtooth quantity, has not only solved the difficult problem of tool bit welded and has still reduced manufacturing cost.
The utility model provides a saw bit body thickness of A piece saw bit and the B piece saw bit of biplate combination saw bit is 3.5mm, and the thickness sum of two saw bits equals super thick saw bit body thickness commonly used, but the width of sawtooth (tool bit) is little a lot of than the sawtooth width of former super thick saw bit, more is applicable to high frequency welding, and not only can not have welding strength not enough, and the problem of carbonization tool bit has still practiced thrift the weld time. The utility model provides a A piece saw bit and B piece saw bit's sawtooth total number equals the sawtooth quantity of former super thick saw bit, because the sawtooth width is far less than the sawtooth width of former super thick saw bit for when the high frequency welding of being more convenient for, can also reduction in production cost.
