Description

Be applicable to the refrigerating unit of double frequency hard surfacing device
Technical field
The utility model relates to a kind of refrigerating unit that is applicable to double frequency hard surfacing device.
Background technology
Quenching technology is that steel is heated to the above a certain temperature of AC3 or AC1 point, keeps certain hour, then with suitable speed cooling obtain martensite and (or) thermal treatment process of bainite structure.The purpose of quenching is to improve hardness, intensity, wear resistance to satisfy the use properties of part.Quenching technology is most widely used, as instrument, measurer, mould, bearing, spring and automobile, tractor, diesel engine, machining lathe, pneumatic tool, roll etc.Quenching temperature is determined according to composition, tissue and the different performance requriementss of steel.Hypoeutectoid steel is AC3+(30~50 ℃); Eutectoid steel and hypereutectoid steel are AC1+(30~50 ℃).So both guarantee abundant austenitizing, kept the tiny of austenite crystal again.The quenching temperature of hypereutectoid steel generally is recommended as AC1+(30~50 ℃).In actual production, also according to circumstances suitably improve about 20 ℃.At this temperature range internal heating, it is organized as the austenite and the tiny equally distributed undissolved carbide of part of small grains.Outside the quenching after depolarization minority residual austenite, it is organized as equally distributed tiny carbide particle on the plate martensite matrix.Like this organize hardness height, wear resistance good, and fragility is less relatively.When in production practice, selecting the quenching temperature of workpiece, except observing above-mentioned rule, also to consider all multifactor influences such as chemical ingredients, technical requirements, size shape, original structure and heating installation, heat-eliminating medium of workpiece, Heating temperature is suitably adjusted.All finish structural transformation, carbide dissolving and austenitic homogenization of composition for each several part inside and outside making workpiece, just must be incubated certain hour at quenching temperature.Workpiece carries out the employed medium of quench cooled and is called quenching medium (or quenchant).The condition that the ideal quenchant should possess is to make workpiece can quench into martensite, unlikelyly again causes too big quenching stress.Quenchant commonly used has water, the aqueous solution, mineral oil, fused salt, molten alkali etc.Water is the stronger quenchant of cooling power.The source is wide, price is low, water is in the steam film stage, cools off soon inadequately, can form " soft spots "; Water is in boiling stage, cools off too soon, easily makes the martensitic transformation excessive velocities and produces very big internal stress, causes workpiece deformation even cracking.When water temperature raises, contain in the water and sneak into insoluble impurity (as oil, soap, mud etc.) in more gas or the water, all can significantly reduce its cooling power.Therefore water is applicable to that sectional dimension is little, the quench cooled of the carbon steel workpiece of simple shape.
The hard surfacing principle is that workpiece is placed in the inductor block of using the hollow copper tubing coiled, after feeding power frequency, intermediate frequency or high-frequency alternating current, the strong flux of polarization instantaneous variation in coil, heated materials such as metal are placed in coil, flux will connect whole heated material, the direction inner opposite with heating current at heated material produces very big eddy current, because the resistance in the heated material produces joule heating, the temperature of material self risen rapidly.Workpiece surface form same frequency induced current, piece surface is heated water spray cooling (or oil quenching) immediately after (800~1000 degree that can heat up in several seconds, heart portion is still near room temperature) rapidly, the workpiece surface layer is hardened.Frequency is selected in requirement according to thermal treatment and heat penetration, and the degree of depth of the high more heating of frequency is shallow more.Ratio-frequency heating generally is used for the heating of middle-size and small-size part, as fine module gear and medium and small axial workpiece etc.Heating in medium frequency generally is used for the gear heating of big axle class of diameter and big-and-middle modulus.The power frequency heating generally is used for the diathermanous of large-size part, for example the hard surfacing of the roll more than the diameter 300mm.
There is a good problem to study to be now, which kind of device realizes the hard surfacing of roll with, and obtain best effect.
Summary of the invention
The utility model provides and is to provide a kind of refrigerating unit that is applicable to double frequency hard surfacing device, thereby solves the surface-cooled problem that realizes roll.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of refrigerating unit that is applicable to double frequency hard surfacing device, it is connected with the pond in turn by pipeline, working shaft, control valve and water-jet 32, be with a telescopic water collector cover on the outside of described water-jet, described water-jet is by upper sealing plate, erecting frame, inwall, outer wall and following shrouding surround a sealed cavity, on described inwall all be distributed with spout hole, on described outer wall, waterpipe jointing is installed, on the described upper sealing plate erecting frame is installed, described telescopic water collector cover is superposeed successively by plural right cylinder and forms, inner becket that is provided with by the edge of right cylinder own between described two right cylinders and outer latch closure clamping form integral structure, the below of described telescopic water collector cover is provided with header tank, and by pipe connection, described header tank by pipe connection on the pond.
The hole heart of described spout hole is the intersection point of two groups of parallel lines, and the scope of the angle of cut θ of two groups of parallel lines is 60 ~ 90 °.
The utility model is simple in structure, and is easy to use, and cooling performance is obvious.
