Description
Technical field
This utility model relates to metallic alloying Casting Equipment field, is specifically related to a kind of vibrating device casting platform.
Background technology
In production, Large Steel iron castings time, generally use hard sand mold, after mould assembling cast, cast case be placed on casting platform, wait foundry goods natural cooling.Liquid metal is during static cooled and solidified, and owing to foundry goods overall structure wall thickness variation is big, common process is all difficult to ensure that overall equilibrium cooling, and local is easily generated the defects such as crackle, shrinkage porosite, shrinkage cavity, slag inclusion, coarse grains.Particularly large-scale steel-casting, through Non-Destructive Testing, casting flaw is especially prominent, and soldering, finishing workload increase, and percent defective is higher, strengthens production cost.Be badly in need of now one can jolt ramming liquid, strengthen feeding, stir impurity, gas floats up to surface, and densification is gradually organized, and reduces the vibrating device of the casting platform of soldering reclamation work amount.
Utility model content
The purpose of this utility model be provide one can jolt ramming liquid, strengthen feeding, stir impurity, gas floats up to surface, and densification is gradually organized, reduce soldering reclamation work amount casting platform vibrating device.
The base case that this programme provides is: the vibrating device of casting platform, including frame, spring, chute, is arranged on the guide wheel below casting platform and eccentric motor；Frame includes vertical portion and horizontal component, and chute is fixedly connected on horizontal component, and spring one end is fixing with vertical portion to be connected, and eccentric motor is fixed on the horizontal component of frame, and the rotating shaft of eccentric motor is provided with connecting rod, and connecting rod is hinged with casting platform；The spring other end is fixing with casting platform to be connected, and guide wheel is positioned at chute.
Operation principle and the advantage of this programme are: first, after mould assembling is poured into a mould, are fixed on by cast case on casting platform.Owing to guide wheel is provided in casting below platform, and guide wheel is positioned at chute, and spring connects the vertical portion of casting platform and frame, and under the elastic force of spring, the vertical portion branch of casting platform and frame keeps spacing.Then eccentric motor is started, the rotating shaft of eccentric motor drives casting Platform Vibration by connecting rod, the frequency of vibration of eccentric motor can realize by selecting the motor of different rotating speeds, or by installing belt pulley additional, the frequency of vibration that eccentric motor is provided is 20-100 time/second, is as the criterion not destroying sand mold.
The spring being arranged on frame vertical portion is possible to prevent casting platform when vibration, occurs that casting platform strikes the situation of frame, and casting platform is after striking frame, due to the change of frequency of vibration, and the effect of inertia, the situation that sand mold is destroyed easily occurs.Spring serves cushioning effect, and when vibration, spring can coordinate eccentric motor, and without eccentric motor, spring can apply the power of auxiliary break-in so that be more prone to during casting platform break-in to casting platform during vibration break-in.
The vibrating device of this programme casting platform, make liquid metal during cooled and solidified, casting platform is applied little amplitude, high-frequency vibration, makes liquid metal in vibration processes, the branch of broken Dendritic TiC mushrooms out power core, reach crystal grain thinning, strengthen feeding, it is simple to gas, burning into sand emersion liquid level, improve Internal Quality of Cast, in making, heavy castings obtain the higher fine and close metallographic structure of mechanical performance, improve the disposable percentage of A-class goods of foundry goods, reduce soldering workload.
Preferred version one: based on the preferred version of scheme, spring is provided with at least two, and spring is each attached in frame vertical portion.On the one hand, multiple springs can increase elastic force, on the other hand, it is ensured that elastic force is applied to cast the central point of platform.
Preferred version two: based on the another preferred version of scheme: eccentric motor is frequency conversion motor.The frequency of frequency conversion motor is convenient to be controlled, and is adapted to different materials, different frequency of vibration, improves the versatility of device, fast and easy.
Preferred version three: the preferably preferred version of two: be provided with butter layer in chute, butter layer thickness is 0.2mm-0.5mm.Butter layer can reduce the friction between guide wheel and chute, improves the vibration efficiency of casting platform.
Accompanying drawing explanation
Fig. 1 is the structural representation of the vibrating device embodiment of this utility model casting platform.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Reference in Figure of description includes: frame 1, spring 2, chute 3, frequency conversion motor 5, connecting rod 6, casting platform 7.
Embodiment is the most as shown in Figure 1: the vibrating device of casting platform 7, including 1, two springs 2 of frame, chute 3, is hinged on the guide wheel below casting platform 7 and eccentric motor；Frame 1 includes vertical portion and horizontal component, chute 3 is welded on horizontal component, and one end of two springs 2 is all welded with vertical portion, and eccentric motor is bolted on the horizontal component of frame 1, being welded with connecting rod 6 in the rotating shaft of eccentric motor, connecting rod 6 is hinged with casting platform 7；The other end of two springs 2 all welds with casting platform 7, and guide wheel is positioned at chute 3；Motor is frequency conversion motor 5, is provided with butter layer in chute 3, and butter layer thickness is 0.2mm-0.5mm.
Time specifically used: first, after mould assembling is poured into a mould, cast case is fixed on casting platform 7.Owing to guide wheel is provided in casting below platform 7, and guide wheel is positioned at chute 3, and spring 2 connects the vertical portion of casting platform 7 and frame 1, and under the elastic force of spring 2, the vertical portion branch of casting platform 7 and frame 1 keeps spacing.Then eccentric motor is started, the rotating shaft of eccentric motor drives casting platform 7 to vibrate by connecting rod 6, the frequency of vibration of eccentric motor can realize by selecting the motor of different rotating speeds, or by installing belt pulley additional, the frequency of vibration that eccentric motor is provided is 20-100 time/second, is as the criterion not destroying sand mold.
