The specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and in conjunction with the specific embodiment for the below.
Shown in Fig. 1,2,3,4, be common to the induction heating apparatus of Sand-Faced Metal Mould Casting production line, be connected in going out between foundry goods device and the swage sand shake-out device using of Iron Mould Coated Sand equipment, comprise roller-way conveyer frames 1 and the swage 2 and the heating component that support, be used for Iron Mould Coated Sand technique to the heating operation of swage, it is characterized in that: roller-way conveyer frames double track 3 inboards are provided with bearing 4, overlapping carrying roller foreign steamer 5 on the bearing 4, swage 2 is placed on the transmission track of roller-way conveyer frames 1, and is supported by carrying roller foreign steamer 5; The transmission track of roller-way conveyer frames 1 is provided with induction coil 6 big or small and that swage 2 is complementary, and induction coil 6 is fixing by bakelite lattice framing 7; Induction coil 6 outsides also are covered with arch shell 8, and arch shell 8 is fixedly connected with roller-way conveyer frames double track 3 with bakelite lattice framing 7 respectively, induction coil 6 draw coil interface 9 with and be connected with the major loop of induction power supply 10.
Roller-way conveyer frames double track 3 inboard set bearings are heat-resisting bearings; Induction coil is connected and fixed by stainless steel bolt and nut by bakelite lattice framing 7; Coil interface 9 is provided with power supply access port and cold water access port; The major loop of induction power supply 10 is provided with power switch cabinet 11, power supply frequency conversion and rectifier cabinet 12, capacitor group 13.
The induction heating apparatus that is common to the Sand-Faced Metal Mould Casting production line that the utility model provides, in diesel engine flywheel blank production process, the heat that at first uses iron liquid in the last round of production process to solidify to discharge improves the swage temperature, when detecting the swage temperature less than 220 ℃ ± 10 ℃ of technological requirement, when it passes through induction coil along the roller-way conveyer frames, with its stop; Introduce cooling water from the cold water access port of coil interface, coil interface is connected induction power supply, allows 1000HZ, 380V alternating current by induction coil, reaches the inside and outside and produce the intermediate frequency variation magnetic field around swage, and produce a large amount of eddy current in swage.Because the swage material resistance is larger, produces larger heat.The external magnetic field then goes back to inside by aluminum shell.Because the sheathing material magnetic resistance is little, resistance is little, does not produce larger heat.After the heating 30～50, a second swage temperature reaches 230 ℃ ± 5 ℃, finishes heating process; By the roller-way conveyer frames swage is transported to next station again, through the cooling of knockout station, the swage temperature will reach covers 220 ℃ ± 10 ℃ of the suitable temperatures that layer of sand solidifies.
Facts have proved that in a large number the induction heating apparatus that is common to the Sand-Faced Metal Mould Casting production line is a kind of easy and simple to handle, cost of labor is low, and production process is continuous, and energy consumption is low, swage be not easy in early days to lose efficacy and also be common to various model castings production swage fast, heater accurately.
After using the utility model technology, need not from production line the swage handling to be entered box-annealing furnace again, when detecting the swage temperature when low, start heater by the employee of knockout station and get final product, the arrangement personnel carry out swage and heat in addition.
Heating-up temperature can accurately be controlled at the curing situation that can accurately cover layer of sand in 230 ℃ ± 5 ℃ scopes, owes to solidify the pore class waste product that causes and descends more than 90% owing to cover the sand holes class waste product that the layer of sand overcuring causes and cover layer of sand.
Need not to use trolley type annealing furnace or the extremely low diesel combustion stove of the thermal efficiency of 160KW, the energy consumption of every heating one sections type only is: 0.30kwh again.Originally with the batch-type furnace average every type power consumption of actual production process 16.0kwh then.
Heat every sections type (being heated to 230 ℃ from common 150 ℃), only need about 40S, and the productive temp of production line be 30 types/hour, can not impact production.
The many-side of the induction heating method of Sand-Faced Metal Mould Casting production line and traditional heating method contrasts such as following table:
From upper table comparative analysis as seen, that the relative traditional heating device of the utility model has is simple to operate, cost, adaptable advantage, more accurate to the control of temperature simultaneously, adopt heater of the present utility model and method, isodose is got the swage heating, energy efficient 98%, the efficiency of heating surface improves 3 times, and because production process is uninterrupted, production capacity will improve greatly than traditional heating means.
