The beneficial effects of the present invention are: when being higher than the reference upper level value according to the plate temperature value by the temperature control unit Controlling the coolant liquid machine accordingly reduces the liquid temperature value of the coolant liquid exported, can make the coolant liquid machine only in necessary situation The lower movement just to cool down, so as to achieve the purpose that automatic temperature-control to reduce energy consumption.
Detailed description of the invention
Other features of the invention and effect will be clearly presented in the embodiment referring to schema, in which:
Fig. 1 is a three-dimensional combination figure, illustrates one embodiment of the hollow sheet metal forming cooling device of the present invention;
Fig. 2 is the partial cutaway view of the line II-II in Fig. 1;And
Fig. 3 is a block schematic diagram.
Specific embodiment
Refering to fig. 1 and it is defeated along one to be suitable for cooling for Fig. 2, one embodiment of the hollow sheet metal forming cooling device of the present invention A hollow plate 10 for sending direction to convey, and include first cooling piece 1, one along the conveying direction be arranged at intervals at this 2, coolant liquid machines 3 of the second cooling piece of one cooling piece 1 and a temperature control unit 4.
Each cooling piece 1,2 include general plate-like ontology 11,21, be located at the ontology 11,21 along the conveying side To opposite end face respectively for inputting and exporting the feed inlet 12,22 and a discharge port 13,23, one of the hollow plate 10 It is a to run through the setting ontology 11,21 and be connected to the feed inlet 12,22 and the cooling feed track 14 of the discharge port 13,23,24, difference The ontology 11, two coolant inlets 15,25 of 21 top surface two opposite sides and two cooling liquid outlets 16,26 are opened in, and more A cooling liquid flowing channel for being set to the ontology 11,21 and the connection coolant inlet 15,25 and the cooling liquid outlet 16,26 17,27.The top surface court that the coolant inlet 15,25 of each cooling piece 1,2 is located at the ontology 11,21 is away from the coolant liquid machine 3 side, the cooling liquid outlet 16,26 of each cooling piece 1,2 are located at the top surface of the ontology 1,2 adjacent to the coolant liquid machine 3 Side.The hollow plate 10 sequentially passes through the cooling feed track 14,24 of first, second cooling piece 1,2 along the conveying direction, and has There is an interlude 101 between first, second cooling piece 1,2.It should be noted that each cooling piece 1,2 is cold But the quantity of liquid entrance 15,25 and the quantity of cooling liquid outlet 16,26 are also possible to one or three or more value.Each cooling The quantity of the cooling liquid flowing channel 17,27 of part 1,2 is also possible to one.
The coolant liquid machine 3 exports the coolant inlet 15,25 of a coolant liquid 31 to each cooling piece 1,2, and receives The recycling coolant liquid 32 to flow back from the cooling liquid outlet 16,26 of each cooling piece 1,2.Wherein, the coolant liquid 31 and should Recycling coolant liquid 32 by multiple Pipeline transports and is recovered between the coolant liquid machine 3 and each coldplate 1,2 respectively, and flowing side To as illustrated by the arrows in fig. 1.
Cooperate again refering to Fig. 3, which includes three temperature-sensitive stickers being intervally installed 41, one Reference temperature generation module 42 and a comparator 43.The temperature-sensitive sticker 41 is disposed adjacently in second cooling piece 2 Feed inlet 22, and receive the hollow plate 10 interlude 101 a plate temperature to export the plate temperature value for being relevant to the plate temperature Tpp.The reference temperature generation module 42 receive respectively one be relevant to the thickness of slab value of 10 thickness of hollow plate, one be relevant to this The velocity amplitude of the conveying speed of hollow plate 10 and one are relevant to the house temperature of environment temperature, and according to the thickness of slab value, the speed Value and the house temperature are to generate a reference upper level value THAn and reference lower limit value TL.Wherein, it is common in general hollow plate production In thickness of slab value between 2~10mm, velocity amplitude between 5~15m/min, that is to say, that the thickness of slab value difference under different working conditions There are up to 5 times of range, velocity amplitude difference also to have 3 times of range, therefore different working conditions is corresponding to different with reference to upper Limit value THAnd reference lower limit value TLSetting can more precisely reach energy-efficient effect.It should be noted that temperature-sensitive sticker 41 Quantity is also possible to one, two or four or more value.
The comparator 43 compares plate temperature value TppWith reference upper level value TH, and in plate temperature value TppHigher than the reference upper level Value THWhen, which controls a liquid temperature value of the coolant liquid machine 3 to reduce the coolant liquid 31.The comparator 43 Also compare plate temperature value TppWith reference lower limit value TL, in plate temperature value TppLower than reference lower limit value TLWhen, temperature control Unit 4 controls the coolant liquid machine 3 to increase the liquid temperature value.It should be noted that since each temperature-sensitive sticker 41 is exported Plate temperature value TppMay not be identical, thus the comparator 43 in carry out temperature value comparison before, optionally (such as each The setting position of temperature-sensitive sticker 41) to the plate temperature value TppA corresponding operation is executed to obtain an Equivalent Plate temperature value T’pp, reuse the effect plate temperature value T 'ppRespectively with reference upper level value THAnd reference lower limit value TLIt compares.
Via above explanation, above-described embodiment is had the advantage that
One, by the temperature control unit 4 according to plate temperature value TppHigher than reference upper level value THWhen control the coolant liquid Machine 3 accordingly reduces the liquid temperature value of the coolant liquid 31 exported, can make the coolant liquid machine 3 only in just carrying out if necessary The movement of cooling, so as to achieve the purpose that automatic temperature-control to reduce energy consumption.
Two, plate temperature value T is also compared by the temperature control unit 4ppWith reference lower limit value TL, and in plate temperature value Tpp Lower than reference lower limit value TLWhen, which controls the coolant liquid machine 3 to increase the liquid temperature value, to be avoided that The coolant liquid machine 3 operates in the low-temperature condition more to consume energy further to save the energy.
Three, the thickness of slab value, the velocity amplitude and the house temperature are received also accordingly to adjust this by the temperature control unit 4 Reference upper level value THAnd reference lower limit value TL, to can all play energy-efficient effect under different working conditions.
In conclusion apparatus of the present invention can reach the purpose of the present invention really.
The above, only the embodiment of the present invention, when cannot be limited the scope of implementation of the present invention with this, i.e., it is all according to Simple equivalent changes and modifications, all still belong to the scope of the present invention made by claims of the present invention and description.
