Abstract
The invention discloses a forging heating furnace of an automatic furnace temperature adjusting system. An induction coil is horizontally distributed in a hearth of a heating furnace body; a material pushing air cylinder is arranged on a working tabletop adjacent to the heating furnace body; an electric control cabinet is arranged in a worktable; a controller is arranged in the electric control cabinet; a temperature sensor is mounted at a blank outlet; the induction coil in the heating furnace body is used for heating a blank workpiece; the output end of the temperature sensor is connected with the input end of the controller; when the actual temperature of the workpiece is the same as the pre-set temperature, the controller sends out an unloading instruction and inputs the unloading instruction to an air cylinder; and a push rod of the air cylinder is used for pushing the blank workpiece out of the heating furnace. The blank discharging temperature is 1250+/-20 DEG C, and the heating furnace adopts a middle-frequency electromagnetic induction heating furnace. The heating furnace is internally provided with a heat dissipation device, and a temperature measuring instrument is mounted on an outer wall of the heating furnace.
Description
Technical field
The present invention relates to a kind of forge furnace of furnace temperature automatic regulating system, the slab temperature being to ensure that in heating furnace is
1250 ± 20 DEG C, it is particularly well-suited to forge use on induction heater.
Background technology
Currently, forging induction heater (below 1000kw) of middle low power, due to being simple to manufacture, cheap, is deeply subject to
The favor of China's forging industry, but forging induction heater in temperature cannot control well, blank enter in hot heating furnace,
Furnace temperature is too low or too high, and the slab temperature come out of the stove can be made not reach the requirement specified, thus bringing to follow-up machining
Strong influence, moreover, uniformly whether, after sending into heating furnace, blank local heating is supercool or overheated, it will lead for in-furnace temperature
Cause the section temperature of blank excessive, thus affecting the quality of product.
How to develop furnace temperature temperature in forging induction heater can control at 1250 ± 20 DEG C, and heating process is realized
Nobody automatically controls the target being those skilled in the art's sustained improvement and innovation.
Content of the invention
The task of the present invention be propose a kind of whole heating process nobody automatically control, substantially increase forging workpiece heating effect
A kind of forge furnace of the furnace temperature automatic regulating system of rate and reliability
The task of the present invention be done in such a way that it is characterized in that: horizontally disposed in the burner hearth of heating furnace body have induction coil, pushes away
On the work top of adjacent place that material cylinder is seated in heating furnace body, in workbench, it is placed with electrical control cubicles, putting in electrical control cubicles has
Controller, temperature sensing body is arranged at billet exit, by induction coil, blank workpiece is heated, temperature sensor in hot body of heater
Outfan be connected with the input of controller, when workpiece actual temperature with set temperature consistent when, controller sends and unloads
Material instructs and inputs to cylinder, and cylinder catch bar is released blank workpiece from heating furnace.Blank tapping temperature is 1250 ± 20
DEG C, described heating furnace uses intermediate frequency electromagnetic induction heater.Equipped with heat abstractor in heating furnace, heating furnace outer wall is provided with
Temperature measuring device.
The present invention has the effect that, the present invention adopts close loop negative feedback temperature control system, and heating process is realized unmanned
Automatically control, heat abstractor in good time dynamic control coolant rate, substantially increase the efficiency of heating surface of forging workpiece, and there is peace
Entirely reliable, easily realize the automatization in production line.
Brief description
Fig. 1 is heating furnace structure schematic diagram；Fig. 2 is the automatic regulating system control block of the present invention.
Drawing illustrates: 1, electrical control cubicles, 2, pusher cylinder, 3, heating furnace body, 4, induction coil, 5, billet exit.
Specific embodiment
Describe embodiment in conjunction with the figures above in detail, as shown in figure 1, horizontally disposed in the burner hearth of heating furnace body 3 have sensing
Coil 4, pusher cylinder 2 is seated on the work top of the adjacent place of heating furnace body 3, is placed with electrical control cubicles 1 in workbench, automatically controlled
Putting in cabinet has controller, is provided with temperature sensor at billet exit 5.
The technical program blank tapping temperature is 1250 ± 20 DEG C, and furnace temp adopts closed-loop feedback control system, heat
By induction coil, blank workpiece is heated in body of heater, the outfan of temperature sensor is connected with the input of controller, temperature passes
Sensor inputs to controller temperature signal in good time, carries out contrasting number deviation by controller, when actual temperature and the setting of workpiece
Temperature consistent when, (deviation is zero), controller sends discharging and instructs and input to pusher cylinder, and pusher cylinder catch bar is work
Part is released from heating furnace.
Described heating furnace uses intermediate frequency electromagnetic induction heater, equipped with heat abstractor in heating furnace, heats furnace outer wall
Temperature measuring device is installed, temperature measuring device can be controlled the unlatching of coolant valve in good time Temperature Feedback to controller by controller
Amount, thus controlling the temperature of heating furnace, rough forging to be heated is positioned in load coil, and intermediate frequency power supply is powered, sense
Answer after being passed through alternating current in coil, alternating magnetic field can produced about, the rough forging workpiece placed in its vicinity is being handed over
In the presence of varying magnetic field, electromotive force can be produced, so that the electronics in workpiece is flowed under the driving of this electromotive force and form faradic current
(vortex).Convert electrical energy into heat energy in the presence of resistance within the workpiece, so that workpiece itself is heated.Sensing heating is not against outside
Thermal source, does not require workpiece to contact with induction coil yet, but by the use of by heated work pieces itself as thermal source.Can be selected not according to frequency
Same heating means, have very high heating power, it is easy to accomplish the automatization in production line.
On the premise of ensureing heating quality, The faster the better for the firing rate of blank, and the technical program design requirement is: 75
Second/part, diameter 45 material, the heat time heating time of other diameter material adjust according to intermediate frequency power supply loading condition.
