Abstract
The invention provides a special tungsten steel-tungsten steel welded type cutter for PCBs (printed circuit boards), which comprises a tungsten steel handle part, a tungsten steel head part and a cutter bit, wherein the tungsten steel handle part and the tungsten steel head part are connected through a silver soldering terminal and the temperature of silver soldering for connecting the tungsten steel handle part and the tungsten steel head is 400-420 DEG C. According to the invention, the tungsten steel handle part and the tungsten steel head are welded through silver soldering at 400-420 DEG C, the performances of tungsten steel cannot be changed at the welding temperature being 400-420 DEG C, and further the aim of recycling can be reached and the cost is lowered; and the special tungsten steel-tungsten steel welded type cutter is superior to a cutter completely made of tungsten steel in price. Moreover, tungsten steel which is a rare metal is saved and the production cost of a plant is lowered.
Description
Technical field
The present invention 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 by this invention 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 present invention takes 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 through the silver soldering sheet with the wolfram steel head.
The silver soldering temperature of said connection wolfram steel shank and wolfram steel head is 400 ℃-420 ℃.
Apparatus of the present invention weld together wolfram steel head and wolfram steel shank through 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.Practice thrift rare metal wolfram steel, reduced the production cost of factory.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further:
Fig. 1 is apparatus of the present invention structure chart.
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 through 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 ℃.
Apparatus of the present invention 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.Through 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.
