Description
Technical field
The present invention relates to a kind of small-sized cutter quenching heating furnace.
Background technology
The movement of instrument and meter for automation factory production, amesdial, the part of the product such as dial gauge are, it is necessary to 1~2.2mm of substantial amounts of Φ
× 50~65mm high-speed reamers, three angular bits, drill gun etc..It is required that 62~65HRC of hardness after Q-tempering, flexibility≤
0.10mm, because cutter is small and elongated, cutting edge is thin, and mill amount is lacked, and once using high-temperature salt bath conventional quenching, (direct quenching is sleeved
Quenching), not only deforming can not be straightened greatly, and easily overheat, easy decarburization, and thermal treatment quality is unstable.Many unit application vacuum
Quenching, it is still unresolved to deform overproof old problem.
The content of the invention
The technical problem to be solved in the present invention is：Overcome deficiency in the prior art, there is provided one kind using and it is easy to operate,
Deflection is small, easily alignment, should not overheat and decarburization, the good small-sized cutter quenching heating furnace of thermal treatment quality stability.
The technical solution adopted for the present invention to solve the technical problems is：A kind of small-sized cutter quenching heating furnace, has
Furnace body is heated, the axial middle position of described heating furnace body is provided with air inlet pipe, and heating is stretched out at the both ends of air inlet pipe
Outside furnace body, one end of the air inlet pipe is connected by pipeline with cooling oil groove, and its other end is provided with thermocouple, in air inlet pipe
Between be provided with corundum furnace tube in opening position, corundum furnace tube is provided with scoop, refractory stove core is arranged with the outer surface of the air inlet pipe,
Heat-insulation layer is provided between refractory stove core and heating furnace body.
Further, the junction of described refractory stove core and air inlet pipe is provided with cavity, and electric heating element is provided with cavity.
Further, described refractory stove core both ends and the junction of heating furnace body madial wall are equipped with fire resisting flange.
Further, the both ends of described electric heating element and the junction of heating furnace body madial wall are equipped with corundum porcelain tube.
The beneficial effects of the invention are as follows：The present invention it is simple in construction, using with it is easy to operate, deflection is small, easily alignment, it is unsuitable
Overheat and decarburization, thermal treatment quality stability is good, works well, and is adapted to batch production.
