Description
Technical field
The utility model relates to field of machining and machinebuilding technology, specifically Bearing Quenching Deformation control mechanism.
Background technology
Quenching strain is the key link of restriction workable efficiency and manufacturing cost always.Domestic equipment, from salt bath furnace early, till now common meshbeltfurnace and more advanced supporting roller furnace, has only reduced to a certain extent deflection, but all there is no special ellipse and the taper deformation that quenching process causes of effectively controlling.Take existing more advanced supporting roller furnace as example, adopted slope blanking, reduced falling that in dropping process, weight causes and pounded ovalizing deflection, but because of workpiece falling velocity or very fast, stress point is a bit (the B point shown in Fig. 2) on little lift guipure, still has no small ovalizing deflection; And because setting point is in the outer rim (the 4b point shown in Fig. 2) of little lifting, very short in the little lifting residence time, even at little lifting guipure, do not stop and directly splash on large lifting guipure, to tapering, cannot adjust.Because thermal treatment thinks in theory, in the former seconds that enter after oil, softer after workpiece heating, the larger strength of dropping is easy to produce oval, preferably falls to normal price; When cooling, different because of the speed of cooling of top and bottom, in good time turn-over, could control taper deformation.It is controlled that namely two-stage promotes on guipure cooling time, falls to being inverted to cooling time on cooling time and the little lifting guipure on large lifting guipure than controlled.
Utility model content
Technical assignment of the present utility model is for the deficiencies in the prior art, and a kind of effective Bearing Quenching Deformation control mechanism that controls oval and taper deformation is provided.
The utility model solves the technical scheme that its technical problem adopts:
Bearing Quenching Deformation control mechanism, comprise body of heater, quenching guipure, blanking swash plate, receiving hopper and lift, described blanking swash plate one end is connected with the quenching guipure of the inner place work piece of body of heater, the other end gos deep in receiving hopper, receiving hopper below is provided with little lift and large lift successively, its innovative point is, the straight plate of afterbody of blanking swash plate is designed to arc plate slowly, sets up the soft curtain that slows down simultaneously, away from arc plate end, setting up the soft curtain of backgauge at oiler place.
Further, the soft curtain of described backgauge is at least greater than the maximum length of large an of workpiece away from the distance of arc plate end.
Compared with prior art, the beneficial effect producing is in Bearing Quenching Deformation control of the present utility model mechanism:
The utility model is simple in structure, changes straight the afterbody of blanking swash plate plate into slowly arc plate, and at oiler place, sets up the soft curtain that slows down, and can effectively slow down the speed while dropping into receiving hopper under workpiece; Can control and under workpiece, drop on the position on little lift setting up the soft curtain of backgauge away from arc plate end, by controlling the taper deformation of further controlling workpiece cooling time of workpiece.
Accompanying drawing explanation
Accompanying drawing 1 is structure of the present utility model and workpiece whereabouts mode schematic diagram.
Accompanying drawing 2 is primary structure and workpiece whereabouts mode schematic diagram.
In figure, 1, body of heater, 2, quenching guipure, 3, workpiece, 4, blanking swash plate, 5, porthole, 6, receiving hopper, 7, little lift, 8, large lift, 9, the soft curtain that slows down, 10, arc plate, 11, the soft curtain of backgauge.
Embodiment
Below in conjunction with accompanying drawing 1,2, Bearing Quenching Deformation control of the present utility model mechanism is described in detail below.
As shown in Figure 2, the Bearing Quenching Deformation control mechanism of primary structure, comprise body of heater 1, quenching guipure 2, blanking swash plate 4, receiving hopper 6 and lift, described blanking swash plate 4 one end are connected with the quenching guipure 2 of the inner place work piece 3 of body of heater 1, the other end gos deep in receiving hopper 6, receiving hopper 6 belows are provided with little lift 7 and large lift 8 successively, again by reference to the accompanying drawings shown in 1, the design innovation point of Bearing Quenching Deformation control of the present utility model mechanism is, straight the afterbody of blanking swash plate 4 plate is designed to arc plate 10 slowly, at oiler place, set up the soft curtain 9 that slows down simultaneously, away from arc plate 10 ends, setting up the soft curtain 11 of backgauge.The soft curtain 11 of described backgauge is at least greater than the maximum length of a workpiece 3 large faces away from the distance of arc plate 10 ends.
By reference to the accompanying drawings 1,2, final purpose of the present utility model is effectively to control ellipse and the taper deformation of workpiece, for this reason, first the arc plate 10 that is evolvent type 200 millimeters of foldings of former blanking swash plate 4 afterbody, the track that workpiece 3 can be glided becomes gradually rail by the gradient downslide along blanking swash plate 4 and moves ahead into straight and even, the arc plate 10 of the strong rail formula of involute urve its objective is and makes workpiece 3 become gradually rail, reduces the shock-produced deformation of workpiece 3 and arc plate 10.It two is, at porthole 5 places, the sagging Stainless Steel Wires soft curtain 9 that slows down is installed, slow down and can replace and change lower than cooling pasta more than 200 millimeters when will work in soft curtain 9 bottoms, be less than 30 millimeters with arc plate 10 spacing, object is that workpiece 3 enters by the soft curtain 9 that slows down, to dab workpiece 3 after oil and slow down, and reduces the ovalizing deflection that shock-produced deformation causes.Its three be for reduce taper deformation, set up the soft curtain 11 of backgauge, control workpiece 3 vertically descend slowly and lightly to the point of A shown in Fig. 1 of little lift 7, control the guipure speed of little lift 7, make workpiece 3 facets cooling, when workpiece 3 turns over the guipure of falling large lift 8, can produce upset, on large lift 8, make again large face cooling, in process of cooling, can there is harmomegathus in size, by adjusting little lift 7 speed, control the time of workpiece 3 on little lift 7, make the harmomegathus on workpiece 3 two sides consistent.
The detailed process that workpiece falls is: at quenching guipure, 2 end places of returning are connect away workpiece 3 by blanking swash plate 4 at 1a point, then workpiece slides to 2a point for 3 times, through the arc plate 10 of blanking swash plate 4 afterbodys, slow down and become rail, at 3a point, continuing to become rail slides, to the soft curtain 11 of 4a point touching backgauge, workpiece 3 vertical drops, drop down onto 5a point and start to control the taper deformation of workpiece 3, and last workpiece 3 overturns at 6a point.
Its processing and fabricating of Bearing Quenching Deformation control of the present utility model mechanism is simple and convenient, and processing and fabricating shown in by specification accompanying drawing, except the technical characterictic described in specification sheets, is the known technology of those skilled in the art.
Although above-mentioned, by reference to the accompanying drawings embodiment of the present utility model is described; but the not restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still within protection domain of the present utility model.
