Abstract
The utility model relates to a nitriding furnace, in particular to an ion nitriding furnace temperature measuring device, and belongs to the technical field of heat treatment equipment. The nitriding furnace temperature measuring device comprises a furnace bottom plate, a furnace body and a thermocouple probe. A furnace cavity is formed by buckling the furnace body on the furnace bottom plate which is connected with a cathode plate through a bottom plate support, the thermocouple probe penetrates through the furnace bottom plate and the cathode plate and extends into the furnace cavity, and the thermocouple probe enters a furnace cavity section and is sleeved with a probe protective cover. The nitriding furnace can effectively obtain the actual temperature of a workpiece nitriding area, the temperature can be controlled conveniently, and a workpiece can be nitrogenized evenly.
Description
Technical field
The utility model relates to a kind of nitriding furnace, is specifically related to a kind of temperature-detecting device of ion nitriding furnace, belongs to the equipment for Heating Processing technical field.
Background technology
Bent axle is in carrying out the ion nitriding process, and nitriding temperature is topmost parameter, and it is to decide according to the material of part with to the technical requirements (being mainly hardness, antifatigue degree etc.) of part, and after temperature determines, the time determines with infiltration layer.Mostly existing electric thermo-couple temperature proofing unit is to pack into from the sidepiece of body of heater, and probe only can detect temperature peripheral in the middle of the nitrogenize district, and in stove temperature be exist anisothermal, in its trend, middle temperature is high; Outward, upper and lower temperature is low.The temperature digital of the temperature control instrument that we see is the detected temperatures of thermocouple probe location registration zone in stove, do not demonstrate the true temperature in crankshaft nitriding zone, cause centre and the two ends nitrogenize of the bent axle of inside and outside circle and whole bent axle inhomogeneous, mostly improved holding temperature compensates in the past, but result is unsatisfactory, is prone to distortion, expands.
The utility model content
According to above the deficiencies in the prior art, problem to be solved in the utility model is: a kind of nitriding furnace temperature-detecting device is provided, can effectively detects the actual temperature in workpiece nitrogenize zone, be convenient to temperature control, make the workpiece nitrogenize even.
Nitriding furnace temperature-detecting device described in the utility model, comprise furnace hearth plate, body of heater, thermocouple probe, body of heater is buckled on furnace hearth plate and forms furnace chamber, furnace hearth plate connects cathode disc by the chassis pillar, thermocouple probe gos deep into furnace chamber inside through furnace hearth plate and cathode disc, and thermocouple probe enters the furnace chamber section and is enclosed within probe jacket.
Thermocouple probe is inserted in furnace chamber by the bottom oven chassis, the temperature detected more approaches actual nitriding temperature, the thermocouple probes of group more than spacing arranges carry out temperature monitoring to the different heights in nitrogenize district, can effectively obtain the actual temperature in workpiece nitrogenize zone, be convenient to temperature and control, make the workpiece nitrogenize even; Probe jacket forms protection to thermocouple probe.
Described thermocouple probe is arranged in the centre circle position that the cathode disc workpiece is put, and workpiece divides inner ring, centre circle outer ring to be placed on cathode disc, and from isothermal curve, the temperature of centre circle can better be reacted actual nitriding temperature.
Described body of heater, furnace hearth plate are provided with refrigerating unit, refrigerating unit comprises the interbedded water courage, the interbedded water courage is arranged in body of heater, furnace hearth plate interlayer, water-in is set respectively on body of heater, furnace hearth plate, water outlet is connected with the interbedded water courage, strong, middle ,Ruo tri-tunnels water inlets that water-in arranges.Three tunnels water inlets liter, protect, be easy to complementary temperature control according to operation stage by strengthening or reducing its flow in cooling, the hot water produced in process of cooling can heat and after treatment for worker's bathing, water after heat loss obtains the refrigeration cycle utilization again, forms high-temperature water and arrives the low-carbon environment-friendly economic circulation pattern of high-temperature water to the heating heat radiation again
Described thermocouple probe gos deep into workpiece height 1/2 position.The temperature of this position of key monitoring, can effectively improve the crankshaft nitriding quality, makes nitrogenize even.
The centre circle that the thermocouple probe pitch arrangement is put at the cathode disc workpiece, carry out stereoscopic monitoring to end and the medium temperature of workpiece, effectively obtains nitrogenize district temperature, by this temperature is regulated and controled, effectively improves the crankshaft nitriding quality, makes crankshaft nitriding even.
The beneficial effect that the utility model compared with prior art had is:
The utility model can effectively obtain the actual temperature in workpiece nitrogenize zone, is convenient to temperature and controls, and makes the workpiece nitrogenize even; The three cooling water inlets in tunnel are easy to complementary temperature control, form the low-carbon environment-friendly economic circulation pattern of high-temperature water to water coolant.
