Abstract

The utility model relates to a large-sized vibrating table, which comprises a vibrating table, an excitation vibrating spring, an excitation vibrator, an anti-vibrating spring, a base and vibrating motors, wherein the anti-vibrating spring is arranged on the base and provided with the excitation vibrator; the two sides of the excitation vibrator are provided with the vibrating motors which are opposite in rotating direction when in running; the vibrating table is arranged above the excitation vibrator; and the vibrating table and the excitation vibrator are connected by the excitation vibrating spring. The large-sized vibrating table has higher excitation vibrating frequency and good sand-shakeout effect, and greatly improves vibrating environmental problem by adopting the double-layer vibration isolation design of the vibrating table and the excitation vibrator; the vibrating motors transmit the vibrational force to the vibrating table by the excitation vibrating spring, thus leading the vibration amplitude of the vibrating table to obtain resonance and amplification, further achieving energy-saving effect and prolonging the service life of the vibrating motors; only the vibrating table needs to bear vibration and impact of highly vibration strength, and the excitation vibrator only bears vibration with lower strength; and by adopting the structure of a supporting spring and an elastic damper, the vibration unbalancedness of the vibrating table is effectively reduced.

Description

Large vibration table

Technical field

The utility model relates to the equipment that foundry's sand is handled regeneration, the large, medium and small type casting mold knockout after specifically a kind of foundry hand moulding and the mechanization moulding cast, the large vibration table that molding sand is separated with sandbox, foundry goods.

Background technology

In the last few years, cast waste sand had caused serious pollution to environment, and simultaneously, the minimizing day by day of high-quality resource and the significantly raising of freight make recycling cast waste sand become the focus of lot of domestic and foreign foundry enterprise and founder author's concern.Along with the increasing of country to new forms of energy industry supporting dynamics, domestic wind power equipment and nuclear power generating equipment development of manufacturing are very fast, and great development has also appearred in the manufacturing of supporting for it wind-powered electricity generation and nuclear power generating equipment foundry goods.According to statistics, only just reach hundreds of families at present, therefore also stimulated the prosperity of relevant Casting Equipment for wind power equipment provides the enterprise of foundry goods.Large vibration table is as a kind of key equipment on the foundry production line, it mainly is the peeling that is used to adapt to heavy castings, what existing shake table generally adopted is the inertial oscillation platform, what the inertial oscillation platform adopted is the single-layer partiting polarization structure, it can produce strong vibration, impact when work, caused serious environmental problem and noise problem.And if large vibration table manufactures and designs improperly, technical merit, quality will be uneven, have in addition can't use, brought very big loss to the user.

Summary of the invention

The purpose of this utility model just is to provide a kind of large vibration table that is applicable to the knockout of large and medium-sized casting mold, and this shake table compact conformation is reasonable, use is reliable, less energy consumption.

The technical scheme that provides according to the utility model, described large vibration table involving vibrations platform, exciting vibration spring, excitor, shock-absorbing spring, base and vibrating motor, shock-absorbing spring is installed on the base, excitor is installed on the shock-absorbing spring, vibrating motor is installed in the both sides of excitor, and the direction of rotation the during running of both sides vibrating motor is opposite; Shake table is installed in excitor top, is connected by exciting vibration spring between shake table and the excitor.

As further improvement of the utility model, described vibrating motor has four, and per two vibrating motors adopt the Hooks coupling universal coupling series connection, are installed in respectively on the framework both ends of the surface of excitor.

As further improvement of the utility model, described shake table is assembled by at least one Turbogrid plates.

As further improvement of the utility model, the side lower surface of described shake table is equipped with support spring.

As further improvement of the utility model, elastic damper is installed also between described shake table and the excitor.

As further improvement of the utility model, the vibrating motor protective cover is installed on the described vibrating motor.

Utility model compared with prior art, advantage is:

1, adopted the double-layer vibration isolating design of shake table and excitor, the vibration environment problem that exists during work has obtained bigger improvement, helps the peeling of heavy castings simultaneously.

2, excited frequency is higher, knockout is effective, the inertia force that the broken knockout of casting mold produces when clashing into Turbogrid plates except dependence, also with the fatigue rupture under the dither, the micropore and the crackle that exist in the casting mold are constantly enlarged under the effect of dither ripple, come off until fragmentation.

3, vibrating motor passes to shake table by exciting vibration spring, makes the amplitude of shake table obtain the resonance amplification, has both reached energy-conservation effect, and less because of the excitor amplitude again, the vibration force that vibrating motor is born is less, has improved the service life of vibrating motor.

4, only shake table need bear the vibration and the impact of high oscillation intensity, and excitor only bears more low intensive vibration; Simultaneously, the impact load that casting mold and when bump vibration produce reduces greatly to the dynamic loading on basis behind exciting vibration spring and twice vibration damping of shock-absorbing spring.

5, adopt support spring and elastic damper structure, reduced the disequilibrium of shake table vibration effectively.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described further.

As shown in the figure, the utility model mainly is made up of shake table 1, exciting vibration spring 2, excitor 3, shock-absorbing spring 4, base 5 everything shaft couplings 6, vibrating motor 7, support spring 8, vibrating motor protective cover 9, elastic damper 10.

As shown in Figure 1, base 5 adopts bolt part to be fixed on ground or the workbench, shock-absorbing spring 4 is installed on the base 5, excitor 3 is installed on the shock-absorbing spring 4, vibrating motor 7 is installed in the both sides of excitor 3, and vibrating motor 7 has four, and per two vibrating motors 7 adopt Hooks coupling universal coupling 6 series connection, be installed in respectively on the framework both ends of the surface of excitor 3, the direction of rotation the when vibrating motor 7 of both sides turns round is opposite; Shake table 1 is installed in excitor 3 tops, is connected by exciting vibration spring 2 between shake table 1 and the excitor 3, and described shake table 1 is assembled by at least one Turbogrid plates 11, so that installation and transportation; Shake table 1 bottom is provided with time sand conveying device that is used to carry broken sand, returns the sand conveying device and can adopt back sand belt or jigging conveyer.

The side lower surface of described shake table 1 is equipped with support spring 8, and support spring 8 is supported on grade level or the support platform; Between described shake table 1 and the excitor 3 elastic damper 10 is installed also; Support spring 8 and elastic damper 10 synergies are played a supporting role when shake table 1 work, prevent that shake table from 1 surpassing width of cloth beat, have improved the anti-resonance vibration performance of shake table 1.
