Abstract
A tungsten steel welding tool special for tungsten steel PCBs (printed circuit boards) comprises a tungsten steel handle, a tungsten steel head and a tool head, wherein the tungsten steel handle is connected with the tungsten steel head through a silver soldering lug. The tungsten steel head and the tungsten handle are welded together by silver soldering, welding temperature ranges from 400 DEG C to 420 DEG C, performance of tungsten steel is not changed by the temperature, reusability is achieved, production cost is reduced, the tungsten steel welding tool is more advantageous than an integrally tungsten steel tool in price, rare metal-tungsten steel is saved, and production cost of factories is reduced.
Description
Technical field
The utility model relates to a kind of cutter, particularly a kind of wolfram steel welding wolfram steel type pcb board dedicated tool.
Background technology
For a long time, pcb board dedicated tool (milling cutter) mode of producing adopts always is traditional processing technology, and is unalterable, promptly uses the processing of whole wolfram steel bar, and is disposable use, can not use again.Therefore exist the waste resource, increase the deficiency of polluting, increasing aspects such as cost.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of wolfram steel welding wolfram steel type pcb board dedicated tool, and used waste and old wolfram steel milling cutter or brill are chewed recycling, can be processed into the different size of length according to different demands simultaneously.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: a kind of wolfram steel welding wolfram steel type pcb board dedicated tool, comprise the wolfram steel shank, and the wolfram steel head, cutter head, the wolfram steel shank is connected by the silver soldering sheet with the wolfram steel head.
The silver soldering temperature of described connection wolfram steel shank and wolfram steel head is 400 ℃-420 ℃.
The utility model device welds together wolfram steel head and wolfram steel shank by silver soldering, employed temperature is between 400 ℃ to 420 ℃ during welding, this temperature fails to change the performance of wolfram steel, reached the purpose that reuses simultaneously, reduced production cost, the whole relatively tungsten carbide tipped tool of price has more advantage.Save rare metal wolfram steel, reduced the production cost of factory.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the utility model structure drawing of device.
The specific embodiment
A kind of wolfram steel welding wolfram steel type pcb board dedicated tool comprises wolfram steel shank 1, wolfram steel head 2, and cutter head 3, wolfram steel shank 1 is connected by the silver soldering sheet with wolfram steel head 2.The silver soldering temperature that connects wolfram steel shank 1 and wolfram steel head 2 is 400 ℃-420 ℃.
The utility model device cutter total length remains unchanged: 38.30mm, and there is the head of wolfram steel head 2 to expect 14.0mm, 14.40mm, 13.50mm etc., its corresponding wolfram steel shank 1 handle material has 24.40mm, 24.0mm, 24.90mm etc.By silver soldering head and shank are welded together, employed temperature is that this temperature fails to change the performance of wolfram steel, has reached the purpose that reuses simultaneously between 400 ℃-420 ℃ during welding.
