Abstract
The invention discloses a rotary-type air drying apparatus of an investment casting shell, which comprises a motor, a support and a shell tray, the motor is used for driving a gear to rotate so that rotation power is generated, the motor drives a transmission gear to rotate, the transmission gear is engaged with a main gear and rotates by following the main gear, a coaxial secondary gear is arranged on a rotation shaft of the main gear, a rotary gear is engaged with the secondary gear, the rotary gear is fixed on the main gear, the support is fixed on the shaft of the rotary gear, and the shell tray is arranged on the support. The rotary-type air drying apparatus has the advantages of reasonable structure, safe and reliable usage, shell can be fully dried, and the shells with same batch have good consistency, labor intensity of workers can be mitigated, and production efficiency is increased.
Description
Technical field
The present invention relates to a kind of airing device, especially relate to a kind of rotary airing device of investment casting shell.
Background technology
Application number 200610017461.5 discloses a kind of technology for making magnesium-alloy fired mold casting type sheel, comprise: molding, model group tree, coat stucco, dewaxing, roasting technique process, the shell tapping temperature of controlling after roasting is 100-300 DEG C, in shell, add fire retardant to soak, infiltrating time is 3-5 minute, after drying, shell is encased in to temperature and is in the stove of 200-400 DEG C and dry, can be used for cast after coming out of the stove, wherein important step is exactly drying of shell and dries.
Application number 201210164493.3 discloses the purposes of a kind of carbonic hydroammonium in model casting, and described carbonic hydroammonium is as the curing agent of sodium silicate shell.Concrete using method: do, harden and dry in five steps at the coating of the every one deck of sodium silicate shell process for making shell, stucco, sky, making curing agent with carbonic hydroammonium, process for making shell hardening process technological parameter is: curing agent concentration: 15～20%; Hardening temperature: 20～25 DEG C; Firm time: 3～10min; Drying time: 30～45min.Its dry efficiency is very low.
Drying of investment casting shell, what current technology generally adopted is that fixing suspension type is dried, and it is omnibearing air-dry that its defect is that the fixing suspension of shell is unfavorable for, causes the shell degree of drying difference of diverse location, can affect intensity and the fineness of shell, thereby affect the quality of final products.On this basis, invented a kind of rotary shell airing device, in drying, shell can rotate along with airing machine, like this shell of diverse location can to drying under equal conditions, avoided drying inhomogeneous phenomenon.Reduced the cycle of drying simultaneously, promoted production efficiency, the quality of shell also improves owing to fully drying greatly.
Summary of the invention
For problems of the prior art, the object of this invention is to provide one can make formwork dry fully, and the shell uniformity of same batch is better.Meet the demand in market, alleviated labour intensity simultaneously, promoted production efficiency and the rotary airing device of the investment casting shell that reduces production costs.
In order to achieve the above object, the present invention is by the following technical solutions: the rotary airing device of investment casting shell, comprise motor, support, shell pallet, described motor produces rotary power for driven gear rotation, described motor band nutating gear rotation, described travelling gear interlock master gear rotates thereupon, the rotating shaft of described master gear is provided with a coaxial inferior gear, described time engaged gears has swing pinion, described swing pinion is fixed on master gear, on the axle of described swing pinion, be fixed with support, on described support, be equipped with shell pallet.Described swing pinion has four, and four described swing pinion models are identical.Described master gear is hollow wheel gear.
Rotary shell airing device proposed by the invention, rational in infrastructure, safe and reliable, can make fully formwork dry, the shell uniformity of same batch is better.And can alleviate labor strength, improve production efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the schematic diagram that is related to of each gear of the present invention.
In figure: 1, travelling gear 2, master gear 3, swing pinion 4, inferior gear 5, support 6, shell pallet 7, motor.
Detailed description of the invention
According to Figure of description and specific embodiment, the present invention is further explained below.
As depicted in figs. 1 and 2, the rotary airing device of investment casting shell, comprise motor 7, support 5, shell pallet 6, described motor 7 produces rotary power for driven gear rotation, described motor 7 is with nutating gear 1 to rotate, described travelling gear 1 interlock master gear 2 rotates thereupon, the rotating shaft of described master gear 2 is provided with a coaxial inferior gear 4, described time gear 4 is occluding with swing pinion 3, described swing pinion 3 is fixed on master gear 2, on the axle of described swing pinion 3, be fixed with support 5, on described support 5, be equipped with shell pallet 6, being applicable to dissimilar shell dries.Described swing pinion 3 has four, and four described swing pinion 3 models are identical.Described master gear 2 is hollow wheel gear.
Working method: motor 7 rotarily drives bottom master gear 2 and rotates, four groups of swing pinions 3 installing on large master gear 2 will rotate around the fixing inferior gear 4 in center, because inferior gear 4 and swing pinion 3 interlocks, so swing pinion 3 self also can rotate simultaneously.The support 5 and the shell pallet 6 that are arranged on swing pinion 3 will rotate, thereby realize the rotation of formwork in dry process.
Motor 7 adjustable speeds, dry the shell of technique to adapt to difference, in mobile air, hang or be positioned over shell on pallet and can realize and comprehensively drying fully.
