Description

A kind of photo-curing rapidform machine warm air heating system
Technical field
The utility model relates to photo-curing make-up machine field, particularly, relates to a kind of photo-curing rapidform machine warm air heating system.
Background technology
Rapid shaping technique is the data that a kind of principle that successively superposes based on material is obtained CAD 3D mathematical model slicing delamination, by the special equipment manufacturing technology of stack shaping successively.The photo-curing rapid shaping utilizes photosensitive resin quick-setting characteristic to grow up under the specific wavelength UV-irradiation.
The photo-curing rapidform machine generally comprises curing light source, beam condenser, light-beam scanner, the resin storage tank of splendid attire liquid photosensitive resin, its saddle of sending ultraviolet light and is dipped in the work supporting block in the resin liquid and drives the vertical movement device that work supporting block moves up and down.The ultraviolet light beam that curing light source sends forms the focal beam spot that projects resin liquid level on the work supporting block saddle through beam condenser and light-beam scanner, thereby the sensitization of resin liquid level is solidified, after workpiece solidifies one deck, need the layer thickness that under the drive of supporting plate, descends, on the surface of cured layer, be coated with the last layer resin then and carry out illumination curing again, make whole work-piece so repeatedly at last.
Obviously, in above-mentioned photocuring process, the making of workpiece is vertically to be displaced downwardly to down the accumulation that one deck finishes successively to form, it is very important to keep the thermostatic control of resin heated temperatures, it directly influences the dimensional accuracy of shaping workpiece in vertical direction, and deviation seriously can cause whole work-piece to be scrapped.
Usually there are two kinds of methods to be used for the photosensitive resin heating of photocurable quick shaping process.
A kind of is the heating plate snead process, and its principle is to go up heating plate all around at resin storage tank, and photosensitive resin is heated.This method is to utilize heating plate directly to be posted on resin storage tank all around resin to be heated, because these heating means cause resin temperature to present high graded outside low high, interior the hanging down, makes heating inhomogeneous.Make workpiece manufacturing process in, along with the decline of workbench, the temperature around the workpiece raises, variation of temperature directly influences the formed precision of each layer of workpiece, causes the distortion of workpiece.Secondly,, can cause this part resin to decompose, wear out for a long time, influence the service life of resin, cause use cost to raise owing to higher near the resin storage tank with the resin temperature of heating plate contact.
Another kind of oil conduction heating, its principle is to inject hot-air in the resin storage tank bottom, and photosensitive resin is heated.This method is to utilize oil to be rolled in resin to be heated around the resin storage tank, its phenomenon will with heating plate directly heat the same, occur equally resin heat inhomogeneous, and resin decomposition, the phenomenon that wears out.
The mode that heats by the continuous circulation of hot-air is subjected to the influence of environment temperature, and resin storage tank is when unpacking, and thermal balance will be broken.Mode heats the little molecular solvent evaporation of the resin of appearance and causes laser instrument to be polluted thus, has influence on the service life of scan mirror, directly causes maintenance cost to raise.
In addition, the resin heating that above-mentioned resin heating means are brought is inhomogeneous, and the evaporation of the little molecular solvent of resin is that existing method is difficult to realize easily resin evenly heating and heating-up temperature thermostatic control precision to the pollution of equipment.
The utility model content
The purpose of this utility model is, at the problems referred to above, proposes a kind of photo-curing rapidform machine warm air heating system, and is simple with implementation structure, temperature control is accurate, with low cost, installation and maintenance advantage easily.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of photo-curing rapidform machine warm air heating system comprises resin storage tank, incubator, heating box, firing equipment, and described resin storage tank embedding cloth is arranged in the incubator; In the middle of described resin storage tank and the incubator is air blanketing; The incubator bottom is provided with the heating box that communicates with it; Be provided with heating and temperature controlling device in the described heating box, the heat that described heating and temperature controlling device produces is passed to by heating box and gives the heating of resin storage tank outer wall in the incubator, and then the resin in the heating resin storage tank.
Further, described heating and temperature controlling device comprises: fan, electric heater, first sensor, first thermostatically-controlled equipment, second sensor, second thermostatically-controlled equipment, described first thermostatically-controlled equipment is electrically connected with first sensor and electric heater respectively, and described sensor is arranged in the heating box;
Resin surface is provided with second sensor in the described resin storage tank, and described second thermostatically-controlled equipment is electrically connected with second sensor and electric heater respectively, in order to effective monitoring resin surface temperature;
When the temperature inside the box of heating reaches first thermostatically-controlled equipment and sets temperature, first thermostatically-controlled equipment will cut off the power supply of heater, otherwise the power supply of heater will be controlled by second thermostatically-controlled equipment.
Described fan outlet blows warm braw to resin storage tank and the middle air blanketing of incubator, thereby photosensitive resin is carried out uniform heating over against the electric heater setting, makes the operating temperature of light-cured resin maintain a certain setting value.Thereby improve the formed precision of photocureable rapid shaping workpiece, saved the maintenance cost of equipment.
Beneficial effect
The utility model is simple and reasonable for structure, compact, by adopting the air blanketing in the middle of resin storage tank, incubator to fill warm braw, five methods that face heats to resin storage tank, realize resin heating and thermostatic control, overcome the prior art heating inhomogeneous, to the equipment pollution important disadvantages.The utility model is because during workpiece makes, temperature constant, and when making every decline one cured layer, the precision of moulding is not subjected to the influence that temperature is brought.Improve the formed precision of workpiece, and reduced the maintenance cost of equipment.
