Abstract
The invention discloses a forming-agent-removing mesh-belt furnace which comprises a furnace pipe and a mesh belt. The two ends of the furnace pipe are connected with cover plates which are opened in the movement direction of the mesh belt. According to the forming-agent-removing mesh-belt furnace, the cover plates are movably connected at the two ends of the furnace pipe of the mesh-belt furnace, so that when a press blank enters or exits the furnace pipe, the cover plates are automatically opened and closed. The furnace pipe is sealed to block a leakage passage of protective gases to achieve the aim of reducing the use amount of the protective gases.
Description
Technical field
The present invention relates to a kind of de-forming agent meshbeltfurnace, belong to field of powder metallurgy.
Background technology
The de-forming agent heating furnace using is at present pressed compact is placed on guipure and sends in boiler tube, then passes into protective gas, for example hydrogen, nitrogen, argon gas and combination thereof.These protective gas form protective atmosphere by adding pressed compact and the isolate from outer air of hankering in burner hearth, avoid its oxidation by air.
But the two ends of boiler tube are openings, caused these protective gas to let out from the opening part at boiler tube two ends, thereby needed constantly in boiler tube, to pass into protective gas, caused waste.
Summary of the invention
Goal of the invention: the present invention proposes a kind of de-forming agent meshbeltfurnace, prevents that protective gas from letting out from boiler tube both ends open, reduced the cost of de-forming agent operation.
Technical scheme: the technical solution used in the present invention is a kind of de-forming agent meshbeltfurnace, comprises boiler tube and guipure, and the two ends of described boiler tube are all connected with cover plate, and described cover plate is opened along the guipure direction of motion.
As a further improvement on the present invention, described cover plate is flexibly connected with boiler tube, and this flexible connection is be rotationally connected or be slidably connected.
As another improvement of the present invention, also comprise by motor-operated driving wheel, described driving wheel outer rim is coated with rubber layer.
As of the present invention, further improve, described boiler tube has the warm area of four fixed temperatures, and progressively from room temperature, is heated to 880 degrees Celsius.
Beneficial effect: the present invention is by arranging the cover plate of flexible connection at meshbeltfurnace boiler tube two ends; make pressed compact when turnover boiler tube, automatically open and close cover plate; boiler tube is closed, and the leakage path of blocking-up protective gas, to reach the object of saving and protection gas use amount.Meanwhile, the present invention is provided with rubber layer in driving wheel outer rim, has increased the frictional force between driving wheel and guipure, prevents from skidding.Boiler tube has also been arranged to Three-section type heating, makes heating process more evenly fully.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiment is only not used in and limits the scope of the invention for the present invention is described, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the modification of various equivalents of the present invention.
Embodiment 1: as shown in Figure 1, de-forming agent meshbeltfurnace proposed by the invention comprises an engine 1, and the power of engine 1 output is through reductor 2 and drive chain 3 to rotate.Chain 3 one end are mounted in reductor 2 rotating shafts, and the other end is mounted on sprocket wheel 4.Sprocket wheel 4 is coaxial with driving wheel, two circles form, chain 3 is mounted on one of them circumference, on another circle, mounts guipure 6.Guipure 6 enters in boiler tube 8 through contact roller 5.In boiler tube 8 inside, be provided with along its length seven heat-generating units 12, these seven heat-generating units 12 are controlled separately separately, and the temperature that raises successively forms seven temperature ladders.Below each heat-generating units 12, be provided with corresponding support roller 9, guipure 6 is got back to sprocket wheel 4 places via support roller 9.
The improvements of the present embodiment are A and the B region in Fig. 1, and these two regions are positioned at the two ends of boiler tube 8, are also the main place that protective gas leaks occurs.Hinge 11 as shown in Figure 2, has been installed in a-quadrant on boiler tube 8.Cover plate 10 is also arranged on hinge 11, and cover plate 10, because the gravity of self overhangs below boiler tube 8 and perpendicular to guipure 6, has so just been blocked the leakage path of protective gas.Guipure 6, to the motion of Fig. 2 right side, is driving pressed compact also to move from left to right.When pressed compact contacts with cover plate 10, cover plate 10 under the promotion of pressed compact according to Fig. 2 in the direction of curved arrow upwards rotate.After pressed compact is away from cover plate 10, cover plate 10 resets under the effect of self gravitation, again blocks the leakage path of protective gas.In like manner, region B is also structure as same in Fig. 2.The pressed compact completing after de-forming agent leaves boiler tube 8 from the cover plate 10 of region B, and its process as hereinbefore, is pushed cover plate 10 open by pressed compact, then cover plate 10 automatic leakage path of closed protective gas again under Action of Gravity Field.
The rotation under motor 1 and reductor 2 drives of driving wheel 13 in Fig. 2, driving wheel 13 drives again guipure 6 motions simultaneously.Driving wheel 13 itself is metal material, and guipure 6 is also metal material, so very easily skids between driving wheel 13 and guipure 6, affects the work of meshbeltfurnace.As shown in Figure 3, the present embodiment, at the coated one deck rubber layer 14 of driving wheel 13 outer rims, utilizes the frictional force of rubber to prevent from skidding.
The boiler tube 8 of meshbeltfurnace, in the paper direction of Fig. 1, is divided into the warm area of four fixed temperatures from left to right, carrys out heat stepwise to 880 degree Celsius.As shown in Figure 4, be first heated to 80 ℃ and carry out preheating, and keep 10 hours at this temperature.Then be warming up to 350 ℃, and continue 10 hours at 350 ℃ of temperature.Because 350 ℃ higher than the decomposition temperature of paraffin, paraffin resolves into carbon dioxide and water vapour at this temperature.Then be warmed up to 550 ℃, at this temperature, keep 5 hours, rubber is decomposed.Finally be warmed up to 880 ℃, and at this temperature, keep 2 hours.880 ℃ higher than the decomposition temperature of 376.1 ℃ of stearic acid, and stearic acid resolves into carbon dioxide and water vapour at this temperature.
Embodiment 2: as shown in Figure 5, when pressed compact enters into after heat-generating units 12, cover plate 10 is by manually inserting from the indentation, there of boiler tube 8, and vertically stands on guipure 6 upper surfaces for the region A of the present embodiment and B structure, the leakage path of blocking-up protective gas.And after de-forming agent completes, pressed compact leaves boiler tube 8 from opposite side, also need manually to open cover plate 10, after leaving, again plugs again by pressed compact cover plate 10.Other parts of the present embodiment are identical with embodiment 1.
