The specific embodiment
Below in conjunction with accompanying drawing and enforcement automatic feeding mechanism of the present utility model is further specified.
Fig. 1 is a structure side view under the charging pumping board closed condition of the present utility model; Structure vertical view under Fig. 2 charging pumping board of the present utility model closed condition; Fig. 3 is a charging pumping board open mode mechanical side view of the present utility model; Fig. 4 renovates tip-up state mechanical side view for scarfing cinder of the present utility model; Fig. 5 is the partial enlarged drawing of Fig. 3 of the present utility model, and wherein thicker lines indicate the shape and the layout of ' C ' shape seal groove; Fig. 6 is the B-B cutaway view of Fig. 2 of the present utility model, is wherein mainly indicating the shape and the setting of ' C ' shape seal groove.
As shown in the figure, automatic feeding mechanism of the present utility model is connected on the device body of melting and heat preservation stove, and this mechanism includes hydraulic cylinder and feeding part that links to each other with hydraulic cylinder and scarfing cinder flip potion; Described scarfing cinder flip potion includes scarfing cinder cover base 13, scarfing cinder cover plate turning gear 11 and the pumping board support wheel 15 that is connected with device body 9 by with bolt, between device body 9 and scarfing cinder cover base 13, be provided with the refractory seals pad, generally adopt the thick heat-resisting cotton of 5mm more suitable.On scarfing cinder cover base 13, be stamped the scarfing cinder lid 8 of band C shape seal groove, one side of scarfing cinder lid 8 is connected with scarfing cinder plate turning gear 11, scarfing cinder plate turning gear 11 is to be that pipe and a diameter of 8mm is that 7mm steel axle links together with external diameter 12mm internal diameter, two ends at this steel axle are with screw thread respectively, and be furnished with screw, make things convenient for the dismounting of scarfing cinder lid 8.On scarfing cinder lid 8, be fixedly connected with the protective cover 7 that feeds intake; at the C shape seal groove of scarfing cinder lid 8 and feed intake and be provided with the pumping board 14 that can in C shape seal groove above 8 is covered in scarfing cinder, slide between the protective cover 7; end at pumping board 14 is provided with pumping board handle 5; with this handle scarfing cinder lid 8, pumping board 14 are opened in the lump when being beneficial to scarfing cinder, bring convenience to scarfing cinder.
Used thickness is that steel plate three faces of 4mm are welded into ' Contraband ' shape groove on scarfing cinder lid 8, is called C shape seal groove for convenience, leaves two screwed holes at this above scarfing cinder lid 8, is used for fixing the protective cover 7 that feeds intake.Slide in 14 of the pumping boards C shape seal grooves on scarfing cinder lid 8, there is the gap of 1mm on every limit on the left side of pumping board 14 and C shape groove, the right, the horizontal direction in front, and the vertical direction in the back of C shape seal groove then has the gap of 3-5mm.Also can smooth and easyly slide when deforming under hot conditions with assurance pumping board 14, described distortion mainly shows on the vertical aspect, and sealing mainly shows on the horizontal aspect.
By joint bolt 4 described hydraulic cylinder is connected with pumping board 14, gangbar clip slot and screw device 6 are fixed on above pumping board 14 front ends, apart from pumping board 14 front end 160mm, gangbar clip slot and screw device 6 gangbar clip slot wherein is one and is welded on a clip slot that forms on the pumping board by two block plates, and on clip slot, be provided with screw, skid off outside the clip slot to prevent the gangbar 3 that feeds intake of putting into clip slot.Described feeding part includes to feed intake and turns over groove 16, is provided with the chute 2 that feeds intake in the bottom of turning over groove 16 that feeds intake, and the gangbar that feeds intake 3 one ends are slidingly connected with the chute 2 that feeds intake, and the gangbar that feeds intake 3 other ends are connected/disconnect with pumping board 14 by gangbar clip slot and screw device 6.
Hydraulic cylinder is fixed on below the chute 2 that feeds intake, and the cylinder stroke is 300mm.The hydraulic cylinder movable end couples together pumping board 14 by joint bolt.When hydraulic cylinder extended, pumping board 14 stretched out, sealing dog-house and under the effect of the gangbar 3 that feeds intake, and putting down feeds intake turns over groove 16.In the hydraulic cylinder contraction process, the hydraulic cylinder stroke is during greater than 140mm, under the effect of the gangbar 3 that feeds intake, can dig feeds intake turns over groove 16, this moment material, i.e. magnesium ingot, the upper base of magnesium ingot be 60mm, go to the bottom to 69mm, highly be the trapezoid cross section of 88mm, its length is 575mm, and the effect that magnesium ingot is subjected to gravity slips into dog-house by the roller bearing 1 that feeds intake and enters in the melting and heat preservation furnace apparatus.
This automatic feeding mechanism adopts hydraulic braking, mechanical drive mode to carry out.The feeding mode of dog-house all adopts the mechanical interlock with the charging pumping board to carry out.Adopt screw to be connected at automatic feeding mechanism with the junction of device body 9 (referring to magnesium-alloy quantitative holding furnace equipment here), scarfing cinder lid 8 can freely be dug, pull down, and C shape sealing slot type sealing means is adopted in sealing.The feeding mode of dog-house adopts hydraulic pressure to pump the pumping board mode, and the logical moving gangbar 3 that feeds intake drives to feed intake and turn over groove 16 and finish the action that feeds intake, and the anglec of rotation maximum of turning over groove 16 of feeding intake can reach 45 and spend.
During scarfing cinder; need pull down joint bolt 4 pulls down the hydraulic cylinder link; turn on the bolt on interlock clip slot and the screw device 6; pulling down feeds intake connects moving bar 3; spin-up pumping board handle 5 then; clip slot and screw device 6, the protective cover 7 that feeds intake, 8 meetings of scarfing cinder cover plate link simultaneously in the lump by spin-up, expose square big mouthful above the scarfing cinder cover base 13, this mouth is breast hole.When scarfing cinder finishes; need cycle pumping board handle 5; link simultaneously clip slot and screw device 6, the protective cover 7 that feeds intake, scarfing cinder lid 8 can be rotated in the lump to the home position; cover scarfing cinder cover base 13; with joint bolt 4 with the contraposition of hydraulic cylinder link and link together; with the bolt that the gangbar 3 that feeds intake is put into interlock clip slot and screw device 6 and screwed, can normally feed intake this moment, whole charging realization PLC Automatic Control.
