Abstract
The utility model discloses a swing table of a crankshaft sand box. A guide rod 1 and an air spring 2 of the swing table of the crankshaft sand box are fixedly arranged on a base plates 6 of the equipment; a stand 3 is arranged on the air spring 2 by the guide rod 1 and driven by the air spring 2 to do lifting motion; a sand box 4 is fixed on the stand by positioning blocks on two sides of the stand; and the air spring 2 plays the roles of a spring and a lifting execution mechanism.
Description
Technical field
The utility model relates to a kind of bent axle sandbox plain bumper of casting usefulness.
Background technology
Existing plain bumper mechanical part is made up of frame, cylinder, rubber spring, riser guide and vibrating motor, drive the elevating movement that the guide rail slide block is realized sandbox by cylinder during work, because track passes through bearings, cause the damage of bearing in the jolt ramming process easily, group often needs repairing.On vibration damping, it is rubber shock absorber that former design is adopted, and shock absorber, vibration damping not effect are bad, Equipment Foundations is required high.Plain bumper owing to add the flow unanimity that the shot machine can't guarantee each gaza's mouth, can't guarantee the jolt ramming effect of each shell mould unanimity in the jolt ramming process, cause indivedual shell moulds case that rises serious.The influence of fluctuations that the lifting of plain bumper is stressed is bigger, will work when system pressure is lower than 5.5 atmospheric pressure.
Summary of the invention
Task of the present utility model is the shortcoming at above-mentioned plain bumper structure, and a kind of novel bent axle sandbox plain bumper is provided.The technical solution of the utility model is achieved in that bent axle sandbox plain bumper of the present utility model, form by guide post, air spring, frame, sandbox, locating piece and base plate, guide post, air spring are fixed on the base plate, frame by guide post be installed in air spring above, sandbox is fixed on the frame by the locating piece on frame both sides.
Compared with prior art, the utlity model has following advantage and good effect: the utility model can be realized the linear adjustment of air spring stiffness by adjusting compressed-air actuated pressure, reach best jolt ramming effect, this plain bumper makes vibration more steady owing to have guide post and sandbox detent mechanism that sandbox can be become one with plain bumper simultaneously.Thereby improved the degree of packing of shot, the bent axle flash thickness is obviously reduced, the case waste product that rises is owing to original 0.5% drop to 0.01%.Thereby also improved the utilization rate of molten iron.Owing to there is not consumable accessory, improved the stability of equipment, alleviated the work of service worker.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Specific embodiments
Specific embodiment below in conjunction with accompanying drawing further specifies the utility model.(but not being) to restriction of the present utility model.
Fig. 1 is a structural representation of the present utility model.Referring to Fig. 1, it is made up of bent axle sandbox plain bumper of the present utility model guide post 1, air spring 2, frame 3, sandbox 4, locating piece 5 and base plate 6, guide post 1, air spring 2 are fixed on the base plate 6, frame 3 by guide post 1 be installed in air spring 2 above, sandbox 4 is fixed on the frame 3 by the locating piece 5 on frame both sides.
Bent axle sandbox plain bumper be installed in motor-driven roller-way below, realize the lifting of plain bumper by hand-operated direction valve control air spring, after plain bumper rises, the sandbox of filling it up with shot on the motor-driven rod road is lifted and is fixed by block.After putting in place, rise, realizes the consolidation of shot in the sandbox by the vibration of two vibrating motors in front and back.
