Detailed Description
The invention is further described below with reference to examples, but not to be construed as being limited thereto, and any number of modifications which can be made by anyone within the scope of the claims are also within the scope of the claims.
The invention relates to a method for shaking off high-temperature sand grains on a casting. Through the conveying vibration of conveyer to the foundry goods for the subassembly can vibrate the sand grain on the foundry goods when the conveying gets off, has avoided beating manually through the workman and has shaken off the sand grain on the foundry goods and lead to the problem that high temperature sand grain easily splashes and injures artificial safety hidden danger, thereby has realized the automation of sand grain and has shaken off, safe and reliable, efficient, great reduction workman's intensity of labour.
Preferably, the casting is conveyed and shaken to collect the sand dropped from the casting, so that the problem that the dropped sand splashes to hurt people is avoided.
Referring to fig. 1-8, the device for shaking off high-temperature sand grains on a casting comprises a base 1 and a conveying trough body 2. Base 1 is through four spring unit and conveying cell body 2 elastic connection, and wherein two spring unit are located base 1 and conveying cell body 2's one side, and two spring unit are located base 1 and conveying cell body 2's opposite side in addition. The conveying trough body 2 is internally provided with a conveying frame 3 which is obliquely arranged, and an excitation assembly is arranged above the conveying trough body 2 and used for generating vibration. And a driving component is arranged on one side of the vibration excitation component, and the driving end of the driving component is connected with the vibration excitation component. After the casting is arranged on the conveying frame 3, the conveying trough body 2 elastically mounted on the base 1 shakes through the vibration excitation assembly, and the conveying frame 3 is obliquely arranged, so that the casting can be automatically conveyed along the oblique direction when shaking along with the conveying trough body 2, sand grains on the casting can be effectively shaken off when shaking, the automatic shaking off of the sand grains is realized, safety, reliability and high efficiency are realized, and the labor intensity of workers is greatly reduced.
Specifically, the excitation assembly includes two rotating shafts 4 and two shielding plates 5. Wherein, the below of guard plate 5 is equipped with the connecting plate 18 of arranging perpendicularly with guard plate 5, is equipped with a plurality of vertical arrangement's reinforcing plate 19 on the outside of guard plate 5, and reinforcing plate 19 extends to on the connecting plate 18. Two guard plates 5 are installed respectively in the both sides of conveying cell body 2, and two rotation axis 4 all run through two guard plates 5 in proper order, and two rotation axis 4 pivoted are installed on the guard plate. One end of the rotating shaft 4 is connected with the driving end of the driving assembly, and the other end of the rotating shaft 4 is provided with an eccentric block. In addition, a first protection shell 20 is installed on the outer side of the protection plate 5 close to the eccentric block, and the eccentric block is located in the first protection shell 20 to prevent the eccentric block from being exposed, so that the safety performance of the equipment is improved, and the effect of protecting the eccentric block is also achieved. A second protective shell 21 is installed on the outer side of the protective plate 5 far away from the eccentric block, and the rotating shaft 4 penetrates through the second protective shell 21 and is rotatably installed on the second protective shell 21. When the eccentric block rotates, strong centrifugal force is generated, so that the conveying trough body 2 is driven to shake in the horizontal direction and the vertical direction.
Preferably, the rotating shaft 4 between the two protection plates 5 is sleeved with a protection sleeve 6, and the protection sleeve 6 is fixedly installed on the inner side of the protection plate 5. Through the sealing effect of the protective sleeve 6 on the rotating shaft 4, sand grains are prevented from splashing and striking on the rotating shaft 4 in the shaking process, and the rotating shaft 4 is protected.
Preferably, the two rotating shafts 4 are installed on the protection plate 5 in a staggered manner to enhance the shaking effect of the conveying trough body 2.
The drive assembly protects the drive motor 7 and the coupling 8. One end of the coupling 8 is connected with the driving end of the driving motor 7, and the other end of the coupling 8 is connected with the rotating shaft 4. The driving motor 7 drives the rotating shaft 4 to rotate through the coupler 8, and rotation of the eccentric wheel block is achieved.
The conveyance rack 3 of the present embodiment includes a left side support plate 9 and a right side support plate 10. The left support plate 9 is arranged at one end in the conveying trough body 2, and the right support plate 10 is arranged at the other end in the conveying trough body 2. A plurality of obliquely arranged steel bars 11 are installed between the left and right support plates 9 and 10. That is, the left support plate 9 is higher than the right support plate 10, and the steel bars 11 extend from the left support plate 9 toward the right support plate 10. A sand leakage gap 12 is arranged between two adjacent steel bars 11. When the casting is vibrated, it moves from left to right along the inclined bars 11 and during the vibration, shaked sand particles escape from the sand leakage apertures 12. A shakeout opening is formed in the base 1, a sand collecting cover 13 corresponding to the shakeout opening is arranged below the base 1, and a sand discharging interface 14 is arranged below the sand collecting cover 13. After being shaken off, the sand grains enter the sand grain collecting cover 13 through the sand falling opening to be collected, so that the fallen sand grains are prevented from splashing and hurting people.
The spring assembly includes a spring base 15, a spring platen 16 and four springs 17. Spring base 15 installs on the lateral wall of base 1, and spring clamp 16 installs on the lateral wall of conveying cell body 2, and four spring 17's one end is connected with spring base 15's up end, and four spring 17's the other end is connected with spring clamp 16's lower terminal surface, realizes base 1 and conveying cell body 2 elastic connection.
The working principle of the invention is as follows: placing the casting on a conveying frame 3 of the conveying trough body 2 and enabling the casting to be positioned on the higher side of the conveying frame 3; and starting the driving motor 7, wherein the driving motor 7 drives the eccentric wheel block to rotate through the coupler 8 and the rotating shaft 4. The eccentric wheel block generates stronger centrifugal force in the rotating process, so that the conveying trough body 2 and the casting in the conveying trough body 2 are driven to shake in the horizontal and vertical directions; and in the shaking process, sand grains on the casting can be effectively shaken off without manual cleaning. Because the conveying frame 3 is arranged obliquely, the castings can move to the end of the bottom of the conveying frame 3 along the surface of the conveying frame during shaking, and automatic transmission of the castings is realized. The sand shaken off from the casting enters the base 1 through the sand leakage gap 12 and falls into the sand collecting cover 13 from the sand falling opening of the base 1, so that the splashing of the falling sand is avoided. When the sand in the sand collecting cover 13 is more, the sand in the sand collecting cover 13 is removed through the sand discharging interface 14.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can make various changes and modifications without departing from the structure of the invention, which will not affect the effect of the invention and the practicability of the patent.
