Detailed description of the invention
And the present invention is described in detail in conjunction with the embodiments below with reference to the accompanying drawings.It should be noted that, when not conflicting, the feature in following embodiment and embodiment can combine mutually.
Fig. 1 is the flow chart of the production technology of 3D printing consumables ABS wire rod in the embodiment of the present invention, and as shown in Figure 1, the production technology of 3D printing consumables ABS wire rod comprises the following steps:
(1) get the raw materials ready.By weight, the ABS particle of 92 ~ 95 parts is mixed rear obtained ABS mixed material with the flexibilizer of 4 ~ 6 parts.ABS adopts model to be the ABS material of PA-757, and this kind of ABS material has high circulation, is conducive to the circularity accuracy guaranteeing plastic wire.By increasing flexibilizer in the feed, reducing ABS material fragility and improving shock resistance, can prevent from playing pimple, broken string when printing, improve print quality.
(2) material is dried.ABS mixed material is added the hopper 11 of extruder 1, at 82 ~ 87 DEG C of temperature, dry material 1.5-2 hour at hopper 11 pairs of ABS mixed materials of extruder 1.By carrying out baking material to ABS mixed material, remove the moisture in raw material, prevent bubble, affect print quality.
(3) extrude.ABS mixed material after oven dry enters in extruder 1 barrel 12, screw rod rotate and heater electrical heating effect under to heat up melting, melt enters extrusion die 13 extrusion plastic wire rod under the rotation forces of screw rod; Wherein, described barrel 12 is divided into the firstth district, the secondth district, the 3rd district and the 4th district successively along feedstock direction, following design temperature is heated to respectively to described firstth district, described secondth district, described 3rd district and described 4th district: 172 DEG C, 179 DEG C, 181 DEG C and 185 DEG C, described extrusion die 13 is heated to following design temperature: 168 DEG C ~ 172 DEG C, this temperature regulates according to actual conditions.The rotating speed of described screw rod is 50 ~ 60r/min, and the rotating speed of screw rod regulates according to actual conditions.Barrel is divided into four districts to carry out temperature control, the temperature in the firstth district is lower, preventing temperature to be passed to hopper feed opening makes the temperature of feed opening too high, feed opening being blocked, the temperature in the secondth district increases by 7 DEG C on the basis in the firstth district, and can improve melting effect, the temperature in the 3rd district and the 4th district slowly rises, the abundant melting of raw material can be made, improve melting effect; The temperature of extrusion die is lower, can go bail for and extrude the circularity of wire rod.More preferably, cooled by the charging aperture of cooling device to described barrel, prevent the temperature of hopper 11 feed opening too high, feed opening being blocked.
(4) cool.Plastic wire after extruding, first through naturally cooling, tentatively to lower the temperature, then entering tank 2 and cools.As shown in Figure 1, tank 2 becomes warm water tank 21 and cold rinse bank 22 by baffle for separating, by reservoir 24 for warm water tank 21 provides cooling water, water temperature in reservoir 24 is 40 DEG C ~ 45 DEG C, by cold water storage cistern 25 for cold rinse bank 22 provides cooling water, water temperature in cold water storage cistern 25 is 28 DEG C ~ 30 DEG C, is provided with guide roller 23 in warm water tank 21 and cold rinse bank 22.Wire rod, higher than the water surface, like this, after warm water cooling, is drawn the water surface and is carried out nature cooling by the height of the guide roller 23 of warm water tank 21 end.First through naturally cooling during cooling, then being cooled by warm water, then through naturally cooling, finally cooling in cold water, the plastic wire extruded from extrusion die can be made to avoid through quench, thus cause wire rod to be out of shape, affect circularity precision.
(5) dry.By hair dryer 3, cooled plastic wire is cooled, dry.
(6) detect and regulate.By the scope (1.75mm that measuring device 4 detects the circularity in plastic wire cross section, whether size reaches regulation, 3.0mm, error ± 0.03mm), if not, then by the rotating speed of adjusting screw(rod) and the rotating speed of hauling machine 5 to regulate the size of plastic wire, by regulating the temperature of described extrusion die 13 to regulate the circularity of plastic wire.Be specially to regulate the size of plastic wire by the rotating speed of adjusting screw(rod) and the rotating speed of hauling machine 5: when size is greater than setting, reduce the rotating speed of screw rod, increase the rotating speed of hauling machine 5; When size is less than setting, increase the rotating speed of screw rod, reduce the rotating speed of hauling machine 5.The temperature of described extrusion die 13 is regulated to be specially to regulate the circularity of plastic wire: when circularity is greater than setting, to reduce the temperature of described extrusion die 13.
(7) rolling.Dish is wound into by winder 6 by from hauling machine 5 qualified products out.
The circularity of the 3D printing consumables ABS wire rod obtained by above-mentioned production technology can reach ± 0.03mm, and circularity precision is high, and good stability.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.
