Description
Technical field
The utility model relates to a kind of oil-temperature control device, the oil-temperature control device of drawing oil during particularly a kind of metal is cold-formed.
Background technology
Bar is common metallic article.The machine-shaping of metallurgy industry metal finished product bar, generally can be divided into thermo forming and be hot rolling and cold-formed be two kinds of forms of cold-drawn.High-quality cold drawing of metal bar be the semi-finished metal bar that with drawbench the metal stock cold-drawn is become to meet dimensions, drawing oil is to be used in continuous Cold Drawing Process, reduces friction between drawbench mould and steel, the heat of reduction steel plastic yield generation, the grease of optimization surface quality of steel.Show as thickly at normal temperatures, along with decrease of temperature, it exists form progressively to be tending towards solid-state, can't flow.Make drawing oil performance the best use of, temperature must be controlled at 45 ℃ ± 1.5.
Drawing oil recycles.Oil well pump is had an effect the steel surface that liquid drawing oil in the fuel tank is transported to the mould import and export.The drawing oil sound of rain pattering is back to fuel tank to draw-off tray by oil guide pipe then.
Original drawing oil oil-temperature control device is in fuel tank, and an electrothermal tube heating is installed, and adopts conventional heating with full power method, and drawing oil is heated.Its method of operating is when drawbench send the machine of establishing by cable, starts the drawing oil heating arrangement, treats that the oil temperature in the fuel tank rises, and when drawing oil can flow, drawbench production could normally be carried out.There is certain drawback in this control method: (1) heat conductivility is poor, and heat time heating time is long.According to technological requirement, drawing oil must be heated to 45 ℃ ± 1.5 competence exertion the best use ofs.Make about 0.5M
3Drawing oil be heated to 45 ℃ from normal temperature, electrothermal tube heating with full power needs about 1 hour.When environment temperature is lower than below 10 ℃, when 0 ℃ of left and right sides, drawing oil is solidified as solid-state shape especially, electrothermal tube heats up and can only make grease dissolving among a small circle, make FCL drawing oil oil temperature rise to 45 ℃, need heating more than 3 hours, had a strong impact on the effective activity duration.(2) oily contaminated vapor is serious.Owing to have only an electrothermal tube heating in the fuel tank, the surface of contact of electrothermal tube and drawing oil is less, when the electrothermal tube heating with full power, the surface temperature of electrothermal tube can reach 800-1200 ℃, cause the fluid vaporization of electrothermal tube surface, form a large amount of volatility oil smoke and fill the air whole perform region, serious environment pollution, harm personnel health.(3) control method falls behind, and energy resource consumption is big.The startup of electrothermal tube and to stop be the moving switch control of armrest.Drawing oil is subjected to such environmental effects in performance cooling effect and reflux course, the oil temperature descends, and the fluid thickening need reheat, and therefore frequent transmission or not heat pipe power supply causes the waste of the manpower and the energy.
Summary of the invention
For addressing the above problem, the utility model provides a kind of oil-temperature control device, by preheating control module, heating power control module, the traditional total power manual control mode of temperature control unit replacement, avoid long, drawback such as oily contaminated vapor is serious, energy resource consumption is big heat time heating time, reach the purpose that drawing oil oil temperature is controlled at setting range automatically.
For achieving the above object, oil-temperature control device of the present utility model comprises power supply; Electric heater; Control the heating control apparatus of described electric heater heating; Be used to measure the oil temperature and transmit the temperature sensor that signal is given heating control apparatus; Described heating control apparatus comprises that control oil is heated to the heating power control module that preheats control module, the described electric heater heating power of control of design temperature, the temperature control unit of control oil temperature in the design temperature scope.
The described control module that preheats has the default described control module self-timing control device of start-up time that preheats.
Described electric heater is three electrothermal tubes that are evenly distributed in the fuel tank.
Oil-temperature control device of the present utility model also comprises detecting the mechanical temperature controller of cutting off the electricity supply automatically when temperature is higher than design temperature in the fuel tank.
Oil-temperature control device of the present utility model has realized that the drawing oil temperature controls automatically, and can arbitrarily set the time of preheating as required, has reduced production setup time.
Oil-temperature control device of the present utility model has been realized the drawing oil thermostatic control, has avoided the vaporization of drawing oil under the condition of high temperature, has guaranteed the environmental protection and the safety of production scene.
Description of drawings
Fig. 1 is the block scheme of oil-temperature control device of the present utility model.
Embodiment
Fig. 1 is the block scheme of oil-temperature control device of the present utility model, and as shown in the figure, oil-temperature control device comprises power supply 1, heating control apparatus 2, electric heater 3, temperature sensor 4.Described heating control apparatus 2 comprises and preheats control module 21, heating power control module 22, temperature control unit 23.
Heating power control module 22 is used to regulate the heating power of electric heater 3.
When temperature sensor 4 detected the drawing oil temperature and reaches 45+1.5 ℃ of the setting value upper limit, signal passed to heating power control module 22 through temperature control unit 23.Heating power control module 22 stops the heating of all electrothermal tubes of electric heater 5 at this moment, and the work that preheats control module 21 simultaneously stops.
When temperature sensor 4 detects the drawing oil temperature and reaches 45-1.5 ℃ of setting value lower limit, signal passes to heating power control module 22 through temperature control unit 23, wherein two electrothermal tubes that started electric heater 3 by heating power control module 22 carry out the underpower heating to drawing oil, the heat that loses in the fluid circulation is compensated, and heating power is 35%～40% of a rated power.When temperature sensor 4 detects the drawing oil temperature and reaches 45+1.5 ℃ of the setting value upper limit, stop heating again.
Behind end-of-job, when promptly temperature control unit 23 quit work, the self-timing control device that preheats control module 21 was started working, and prepared for produce next time.
Above the oil level in fuel tank, a mechanical temperature controller 5 is installed, its design temperature is a little more than the design temperature of thermostatically-controlled equipment, and design temperature is 75 ℃.Malfunctioning to prevent heating control apparatus 2, when mechanical temperature controller 5 detects in the fuel tank oil gas temperature and reaches 75 ℃ of design temperatures, cut off the power supply of this device automatically.Increase safety device, stopped hidden danger such as fluid high-temperature evaporation, burning.
