Description

Steel pusher machine for continuously heating furnace

The utility model relates to a kind of pusher.

When metal carries out hot rolling production, generally all be to heat by process furnace, continuous furnace is wherein modal a kind of.And pusher is with carrying steel ingot or steel billet in the dealing continuous furnace.The kind of existing pusher is a lot, and spiral, rack-and-pinion, crank-linkage type and fluid pressure type are arranged.Their something in common is cut somebody's hair all reciprocating exactly.Be working stroke when pushing away steel, shift certain position onto after, must idle motion return, add new steel billet (ingot) then, carry out pushing away the second time steel again.Be interrupted so push away the steel working process, and steel rolling production is a kind of continuous production, need to supply continuously base, and existing pusher can not be accomplished.Simultaneously owing to the productivity that will inevitably influence rolling mill dead time of cutting somebody's hair when returning.

It is higher that the purpose of this utility model provides a kind of production efficiency, pushes away the continuous furnace pusher of steel continuously.

For achieving the above object, the utility model is taked following design: a kind of continuous furnace pusher, it comprises motor, deceleration device, steel billet slide rail and pedestal, described steel billet slide rail is installed on the described pedestal, it is characterized in that: it comprises that also a cover is above by drive sprocket, the transport unit that driven sprocket and chain are formed, guide groove and have pawling of liner more than two, described transport unit is connected with described deceleration device by the main drive shaft on the described drive sprocket, described guide groove is installed on the described pedestal, its position is lower than the vertex of described guide rail, described pawling is installed on the described chain by described liner, described when pawling with described chain movement to the pilled-in selvedge of chain, the described liner on it enters described guide groove.

A plurality of drive sprockets can be by same main drive shaft transmission in said structure, also can distinguish or driven by more than one motor and deceleration device in groups.

The liner that has on described the pawling can be formed with the guide wheel of pawling the side plate that fuses and be rotatably connected on the side plate by two, also can by side plate be connected that slide block on the side plate forms.

Described pawl and being connected of chain is that two ends by side plate are connected on the little axle of two adjacent described chains; Or be connected on by the side plate center hinge on the little axle of described chain; Can also be that front end by side plate is hinged on the little axle of described chain.

The utility model is owing to adopt the transport unit of being made up of sprocket wheel and chain, utilize chain heavy duty, low speed and can rotating characteristics, pawl more than two in installation on the chain, and by the guide groove and the upward liner of pawling, first is pawled when promoting steel billet in stove, and first pawls and second can carry out the steel billet cloth between pawling, and pawls when arriving prescribed position when first, automatically withdraw from pushing away steel, second pawls begins to push away steel in stove.Go round and begin again, realized pushing away continuously the purpose of steel.Especially proper extension chain dimension, and when a plurality of pawling is set, the quantity of each material loading increased, and the steel phenomenon do not occur encircleing, reduced the material loading number of times simultaneously, alleviated workman's work tensity.Not only can boost productivity, can also guarantee successive ordinary production.It can be applied in the steel-pushing apparatus of various medium and small shaped steel productions.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.

Fig. 1 is a structural representation of the present utility model

Fig. 2 is that the utility model pushes away the steel synoptic diagram

Fig. 5 is another embodiment that pawls and install

Fig. 6 is the 3rd embodiment that pawls and install

As shown in Figure 1, motor 1 drives deceleration device 2, and deceleration device 2 can be the master gear speed reduction unit, also can be the various speed reduction units that worm type of reduction gearing or belt, gear, worm and gear etc. cooperate.The output terminal of deceleration device 2 connects a main drive shaft 4 by shaft coupling 3.Main drive shaft 4 is installed on the pedestal 5 rotationally, and two steel billet slide rails 7 that lead to process furnace 6 also are installed on the pedestal 5.8, two drive sprockets 8 of fixedly connected two drive sprockets lay respectively at the both sides of two one slide rails 7 on main drive shaft 4, and drive two by two chains 9 and be connected rotationally on the pedestal 5 by driven axle respectively by movable sprocket 10 by 10, two of movable sprockets.Corresponding with the position of two chains 9, on pedestal 5 two pair cross-sections being installed is " ［］ " type guide groove 11.As shown in Figure 2, the inlet 12 of guide groove 11 is the trumpet type guide openings, and the outlet 13 of guide groove 11 has the inclined-plane otch.The vertex of guide groove 11 is lower than the vertex of slide rail 7, in order to opening steel billet 14 accessible motion on slide rail 7.Install five and pawl 15 on chain 9, pawling has liner 16(as shown in Figure 3, Figure 4 on 15), liner 16 comprises two blocks of side plates 17 and four guide wheels 18.Two blocks of side plates 17 can be on the chain 9 two in flakes, 15 be welded on going up in flakes with pawling as side plate 17.Also 15 and two side plates 17 of pawling can be made of one.Two pairs of guide wheels 18 are installed on the chainlet axle 19, and its distance is a standard chain pitch just in time.

In the foregoing description, if steel billet 14 is long, can be arranged side by side three cover quadruplets even more sprocket wheel transport unit, the guide groove and the device of pawling are also with its increase.Above-mentioned many covers sprocket wheel transport unit can drive a plurality of drive sprockets by a main drive shaft 4 and rotate, and synchronism is better like this.Also can one cover motor 1 and deceleration device 2 be set a cover sprocket wheel transport unit, its supporting capacity is stronger.Can also be divided into several groups more with overlapping the sprocket wheel transport unit, be connected with deceleration device 2 by separately motor 1 respectively.Guide groove 11 can be made respectively with slide rail 7, the making that also can fuse, and its shape also can change.According to cloth and push away steel spatial needs, pawling 15 can be 3,4 or more.The installation of liner 16 on chain 9 of pawling on 15 also can be adopted different forms.As shown in Figure 5, an end of side plate 17 is hinged on the chainlet axle 19, the other end does not connect.As shown in Figure 6, the middle part of side plate 17 is hinged on the chain rivet 19, two ends do not connect.This dual mode also can reach the purpose that pushes away steel, and other form can also be arranged.Guide wheel 18 can also be a slide block in addition, and its frictional coefficient more greatly.

As shown in Figure 2, when motor 1 drove the motion of deceleration device 2 drive sprocket transport units, pawling 15 moved to the chain pilled-in selvedge with chain 9, and the guide wheel 18 of pawling on 15 enters guide groove 11 by entry guide 12, and begins to promote steel billet 14, moves along slide rail 7.15 are subjected to the restriction of guide groove 11 owing to pawl, so can not cause arch steel phenomenon owing to unbalance stress with chain 9 vibrations.Pawl 15 when advancing to the outlet 13 of guide groove 11 when one in front, pawl and 15 withdraw from outlet 13 inclined-planes gradually and push away steel, and move to the slack list of chain with chain 9.Pawling for second 15 promotes first and pawls and second the steel billet 14 between pawling moves forward, and until with after the steel billet 14 of front contacts, just continues to push away steel in process furnace 6.Because two spaces of steel billet of pawling between 15 are very little, and 15 push away in the steel process cloth in the back, therefore can accomplish in process furnace, successively to push away steel in front pawling.
