Description
The utility model relates to the automatic threads feeding apparatus that adds rare earth in a kind of casting process in the motlten metal in crystallizer, belongs to the auxiliary device that is used to handle motlten metal.
Chinese patent ZL91203718.0 discloses a kind of wire feeder that steel pouring process adds rare earth that is used for, mainly by base plate, direct current generator, reductor, gear-box, rare-earth wires inlet tube, advance a velocity sensor, wire feed rolls, silk pressing wheel, regulator, wire leading pipe etc. and form, horizontal direction is equipped with two wire feed rolls at least, the silk pressing wheel is equipped with at the top respectively, and regulator is contained in silk pressing wheel top respectively.The wheeled pinch mechanism of one cover is only arranged on the wire feeder, can only feed a rare-earth wires, the difficult fusion of rare-earth wires mixes when the strand broad, and a series of physical-chemical reactions can not take place effectively, weaken the effect of rare earth on metallurgy, easily caused the inclined to one side plate of composition.When the rare-earth wires fracture of wire occurring, need to handle with the regular hour, cause rare earth in steel billet, to cut in and out, influence the steel billet performance, so that scrap.Adopt the pinch wheel wire feed of handling through annular knurl more than two pairs, rare-earth wires through its repeatedly rolling easily cause rare-earth wires to beat song, the card silk, thus under the effect of pinch wheel pulling force fracture of wire.
The purpose of this utility model provides a kind of simple in structure, and is convenient for installation and maintenance, feeds silk evenly, and the automatic threads feeding apparatus that functional reliability is high with the metallurgical effect of reinforced rare earth, improves slab quality.
The purpose of this utility model realizes by following measure.
A kind of automatic threads feeding apparatus, has base plate, casing, motor, decelerator, wire feed rolls, the silk pressing wheel, screw-down and conduit, casing, motor, decelerator all is installed on the base plate, be set in parallel on the same vertical guide before, back wire feed rolls and its top be installed on the screw-down before, one group of pinch mechanism of the common formation of back silk pressing wheel, the wire feed height respectively is provided with a conduit before and after the pinch mechanism, reductor is positioned at casing, reductor has two symmetrically arranged output axle heads to be stretched out by the both sides of casing respectively, respectively there is one group of pinch mechanism the casing both sides, the preceding wire feed rolls of pinch mechanism is installed on the output axle head of reductor, back wire feed rolls is directly installed on the casing by its rotating shaft, and back silk pressing wheel itself has velocity sensor.
Screw-down is made of cover plate, connecting rod, handle, tie-beam, guide rod and spring, cover plate is mounted on the casing top, the both sides, below are equipped with the guide rod that two verticals are provided with, be set with spring on it, tie-beam matches with guide rod by two pilot hole, being positioned at the middle connecting rod of two guide rods couples together tie-beam and cover plate, its upper end of stretching out cover plate is hinged with the handle that an articulated section is a cam, the forward and backward wired tie-beam both sides that are installed on a screw-down respectively by its rotating shaft of taking turns of every group of pinch mechanism.Control former and later two silk pressings of one group of pinch mechanism by a handle and take turns, adjust the elastic force of spring and can regulate its thrust, simple in structure, easy to operate.
The advantage that the utility model is compared with prior art had is: two covers pinch mechanism and feed silk simultaneously, feed silk evenly, particularly for wide strand, can guarantee that the rare earth composition mixes, strengthen the metallurgical effect of rare earth, when fracture of wire wherein, another root can be with double speed feeding, keep rare earth adding quantity constant, reliable operation, slab quality is improved.Every cover pinches and adopts two pairs of wheels to pinch in the mechanism, and a pair of is that initiatively a pair of is passive, and afterwards silk pressing wheel itself has velocity sensor, simple in structure, easy to maintenance, is difficult for fracture of wire or beats bent.Reductor and screw-down all are arranged in the casing, have reduced the fault that on-the-spot adverse circumstances cause, and have further improved functional reliability.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
Fig. 1 is the structural representation of the automatic threads feeding apparatus of the utility model.
Fig. 2 is the vertical view of Fig. 1.
As shown in Figure 1 and Figure 2, the automatic threads feeding apparatus of the utility model mainly is made of casing 1, reductor 2, preceding wire feed rolls 3, conduit 4, preceding silk pressing wheel 5, cover plate 6, connecting rod 7, handle 8, tie-beam 9, guide rod 10, spring 11, back silk pressing wheel 12, back wire feed rolls 13, motor 14 and base plate 15.Motor 14, reductor 2, casing 1 all are installed on the base plate 15, and reductor 2 is positioned at shell 1.Reductor 2 has two symmetrically arranged output axle heads, is stretched out by the both sides of casing 1 respectively.Casing 1 both sides respectively have one group to be installed on forward and backward silk pressing wheel 5,12 pinch mechanisms that constitute jointly on the screw-down by being set in parallel in forward and backward wire feed rolls 3,13 on the same vertical guide and its top.The preceding wire feed rolls 3 of pinch mechanism is installed on the output axle head of reductor 2, and back wire feed rolls 13 is directly installed on the casing 1 by its rotating shaft, and back silk pressing wheel 12 itself has velocity sensor.The wire feed height is provided with a conduit 4 before and after every group of pinch mechanism.Screw-down is made of cover plate 6, connecting rod 7, handle 8, tie-beam 9, guide rod 10 and spring 11.Cover plate 6 is connected and installed by bolt and is fixed in casing 1 top, the both sides, below are equipped with the guide rod 10 that two verticals are provided with, be set with spring 11 on it, tie-beam 9 matches with guide rod 10 by two pilot hole, being positioned at two guide rods, 10 middle connecting rods 7 couples together tie-beam 9 and cover plate 6, its upper end of stretching out cover plate 6 is hinged with the handle 8 that an articulated section is a cam, and the forward and backward silk pressing wheel 5,12 of every group of pinch mechanism is installed on tie-beam 9 both sides of a screw-down by its rotating shaft.
The automatic threads feeding apparatus of the utility model can be installed on suitable place by the installing hole on its base plate 15 with bolt according to field condition.Before dummy pipe 4, can set up elongate catheter to feeding the silk place as required.During work, lift handle 8, the gap between silk pressing wheel 5,12 and the wire feed rolls 3,13 becomes big, rare-earth wires passes between the front and back conduit 4 and forward and backward wire feed rolls 3,13 and forward and backward silk pressing wheel 5,12 of pinch mechanism, depress handle 8, the gap smaller between wire feed rolls and the silk pressing wheel is finished and is worn silk.The start-up control system, motor rotation, threads feeding apparatus is started working, and feeds silk simultaneously to 2 of crystallizer.Sensor on the back silk pressing wheel 12 is supplied with display and control system simultaneously with the feeding wire speed of measuring, and control system can change according to casting speed dynamically to be adjusted feeding wire speed, guarantees that rare earth adding quantity is accurate.In case rare-earth wires fracture of wire wherein, then the velocity sensor of this pinch mechanism is output as zero, and control system is controlled another set of pinch mechanism in view of the above and fed silk with double in original speed, to keep rare earth adding quantity constant.Warning system is reported to the police simultaneously, prompting staff handling failure.After fault was eliminated, threads feeding apparatus recovered permanent speed.
