Detailed description of the invention
Below in conjunction with embodiment, this utility model is described in further details:
As shown in Figure 1 to Figure 3, this utility model includes a strip cooler bin, and its cross section is " returning " font.Be provided through the cooling duct 1 of a strip in cooler bin from head to tail, one end of cooling duct 1 is hinged with seal cover board 3, and the other end is hinged with attachment strap 4, and wide high and the graphite jig being provided with diamond segment the size of cooling duct 1 adapts.The wall body of cooling duct 1 is connected with the outer wall of cooler bin and forms a cavity 2, the two ends of cooling duct 1 and the two ends of cooler bin and is sealed connected together, and makes this cavity 2 become closed structure.It is separately installed with water inlet pipe 7 and outlet pipe 6 at the two ends of cavity 2, and this cavity 2 is wrapped in cooling duct 1 periphery of inner wall.Coolant enters in cavity 2 from water inlet pipe 7, flows out from outlet pipe 6, the heat given out in simultaneously taking away cooling duct 1 after being full of whole cavity 2.
In use, utilize the instruments such as push rod, the graphite jig equipped with diamond cutter just sintered is cooled down in the dress delivery end of cooling duct 1 pushes cooling duct 1 successively.Several graphite jigs can be arranged successively in cooling duct 1 to cool down simultaneously.After being cooled to assigned temperature, recycling clip, take off the instruments such as hook graphite jig is taken out one by one.The sealed end of cooling duct 1 is also equipped with air inlet pipe 5, and the other end of air inlet pipe 5 is connected with protective gas generating means, and protective gas herein can be hydrogen, nitrogen or decomposed ammonia.Safety when using in view of equipment and Financial cost, preferential selection nitrogen is as protective gas.
The density of the protective gas owing to using in this utility model is below atmospheric density; protective gas is filled with in cooling duct 1 by the starting stage when; one end that should be higher in cooling duct 1 is passed through in cooling duct 1; so protective gas just can be gradually filled with cooling duct 1 from top to down; and will not mix with the air in cooling duct 1, it is ensured that the degree of purity of atmosphere in cooling duct 1.So, this utility model have employed the mode of a kind of inclination and placed on the ground by cooler bin, makes cooling duct 1 and horizontal plane at an angle, and the highest one end is the sealed end of cooling duct 1, and relatively low one end is the dress delivery end of cooling duct 1.In order to make placement that cooler bin tilts on the ground, at the sealed end of cooler bin, this utility model is mounted with that two longer supporting legs, dress delivery end install two shorter supporting legs.
Together with hinge is passed through with the lower edge of cooling duct 1 sealed end in the lower edge of seal cover board 3, seal cover board 3 can rotate the sealed end to cooling duct 1 around bearing pin and open and close.The upper edge of seal cover board 3 is also equipped with a bayonet unit 11, when seal cover board 3 is closed, seal cover board 3 and cooling duct 1 can be locked by this bayonet unit 11, it is also equipped with sealing gasket on seal cover board 3, ensure the sealing of cooling duct 1 sealed end, air inlet pipe 5 is arranged on higher sealed end simultaneously.Such design can reach the purpose making protective gas be gradually filled with whole cooling duct 1 from top to down.
The upper edge of attachment strap 4 fills the upper edge of delivery end and passes through together with a hinge with cooling duct 1, and attachment strap 4 can carry out rotating the dress delivery end to cooling duct 1 around this bearing pin and open and close.And the dress delivery end of cooling duct 1 is provided with a plane, attachment strap 4 can be placed in this plane closes cooling duct 1 and fills delivery end.Attachment strap 4 and cooling duct 1 can be made to fill between delivery end form a gap for protective gas discharge cooling duct 1 with jack-up attachment strap 4 when protective gas is full of whole cooling duct 1.And; when needs use reducibility gas as protective gas, the fuel gas such as such as hydrogen, the gas of spilling can be lighted at attachment strap 4; and the regulation valve regulating air inlet pipe 5 makes to form stable burned flame at gap, it is to avoid fuel gas is diffused in air and explodes after oxygen mix.
Being also equipped with one in the outside of the dress delivery end of cooling duct 1 and be available for the bracket that graphite jig is placed, graphite jig can be shifted onto in cooling duct 1 this bracket with push rod after having cooled down, facilitate workman to take graphite jig away by graphite jig.
Water inlet pipe 7 in this utility model is arranged on one end that cavity 2 is relatively low, and outlet pipe 6 is arranged on one end that cavity 2 is higher.Such design can make coolant be gradually filled with whole cavity 2 from bottom to top, and conveniently makes the coolant after absorption heat move upward along cavity 2 and discharge outside cavity 2.Water inlet pipe 7 is all connected with external water source with outlet pipe 6, and external water source herein includes the devices such as interconnective water pump, aqua storage tank, fin.Water pump is connected with water inlet pipe 7, for being filled with coolant in water route；Aqua storage tank is connected with outlet pipe 6, the coolant discharged in collecting water route；Fin is for reducing the temperature of coolant.
The stop valve 8 and vent valve 9, stop valve 8 and the vent valve 9 that are provided with connection outside air on outlet pipe 6 of the present utility model are installed in series, and stop valve 8 is arranged on the upstream of vent valve 9, and vent valve 9 is arranged on the peak in water route.The effect installing vent valve 9 has two aspects: the air in cavity 2 is discharged toward convenient when being passed through coolant in cavity 2 by the first in the starting stage；It two is outside a small amount of steam device for transferring coolant produced owing to being heated in the cyclic process of coolant.The effect installing stop valve 8 is to prevent coolant from overflowing from vent valve 9.Meanwhile, the low side of cooler bin is also equipped with an industrial temperature meter 10, can monitor the temperature in cooling duct 1 at any time, it is ensured that all graphite jigs and diamond segment are all cooled to assigned temperature.
In case of nitrogen is as protection gas below, illustrate work process of the present utility model:
The first step, closes stop valve 8, lock sealing cover plate 3, opens external water source power supply, makes coolant be filled with cavity 2 along water inlet pipe 7 internal, proves that whole cavity 2 be filled coolant after flowing out coolant in observing outlet pipe 6；Open the regulation valve of air inlet pipe 5 simultaneously, make nitrogen be filled with in cooling duct 1, be then placed at the gap of attachment strap 4 and cooling duct 1 with the small wooden of a burning, in proving cooling duct 1 after small wooden extinguishes, fill with nitrogen.
Second step, opening attachment strap 4, the graphite jig that promptly will be equipped with diamond segment with clip takes out in sintering machine, is placed on cooling duct 1 and fills on the bracket of delivery end, with push rod, graphite jig is pushed in cooling duct 1 by the dress delivery end of cooling duct 1 again, be then shut off attachment strap 4；Repeat said process until filling graphite jig in cooling duct 1.
3rd step, after observing that on industrial temperature meter 10, the temperature of display is less than 200 DEG C, close the regulation valve in air inlet pipe 5, wait 10 minutes again, open attachment strap 4 and seal cover board 3, stretch into push rod from the sealed end of cooling duct 1, graphite jig is released cooling duct 1 by filling delivery end, and piles up and neatly wait form removal.
4th step, repeats second step and the 3rd step, until the graphite jig that in sintering machine, all sintering complete is fully completed cooling procedure.
