Abstract

The utility model belongs to the precision-casting field and discloses a rotation-type braced chain conveyor line for drying a precision-casting shell of a hanger. The rotation-type braced chain conveyor line comprises a braced chain conveyor line, a lifting hook, a hanger and a shell, wherein the shell is connected at the lower end of the hanger; the hanger is connected to the lifting hook through a connecting rod and a connecting sleeve; the upper end of the connecting rod is hinged with the lower end of the lifting hook; the middle-upper part of the hanger is connected with an idler wheel; a plane bearing is arranged between the connecting sleeve and the hanger; a strip-shaped guide plate of the idler wheel is arranged at one side of the hanger and is arranged in parallel with the braced chain conveyor line; the side surfaces of the guide plate of the idler wheel are parallel to the central axis of the lifting hook; and the distance L between the side surfaces of the guide plate of the idler wheel and the central axis of the lifting hook is smaller than the radius of the idler wheel by 1-2mm. When the braced chain conveyor line is used for realizing transmission inside a drying chamber, the hanger and the shell rotate under the drive of the idler wheel by virtue of the friction of the idler wheel and the guide plate of the idler wheel, therefore, after the shell enters the drying chamber, the shell can be dried uniformly as all surfaces of the shell can be blown by air flow.

Description

The dry stretched wire pipeline of suspender rotary type fine casting shell

Technical field

The utility model belongs to the hot investment casting field, relates to the dry pipeline of a kind of precision casting shell.

Background technology

During batch process; The shell of hot investment casting generally is to hang over to send into hothouse on the stretched wire pipeline and carry out drying; Because the position of air-supply is generally fixed in the hothouse, hanging over shell on the stretched wire pipeline, to receive the direction that air-flow blows also be constant basically, and the shell that therefore hangs on the stretched wire pipeline blows more abundant with regard to the airflow on surface that exists; The airflow on surface that has blows inadequate situation, makes the shell uneven drying even.

The utility model content

The utility model provides a kind of simple in structure to the deficiency of prior art, can make suspender, shell in course of conveying, realize rotating, thereby makes the dry stretched wire pipeline of the evenly dry suspender rotary type fine casting shell of shell.

The utility model is realized technical goal through following technical proposals.

The dry stretched wire pipeline of suspender rotary type fine casting shell; It comprises stretched wire pipeline, suspension hook, suspender, shell; Shell is connected the suspender lower end; Its improvements are: said suspender is connected on the suspension hook through connecting rod, adapter sleeve, and the upper end of said connecting rod and the lower end of suspension hook are hinged, and the said central axis that is hinged is parallel with the guide rail of suspension hook position; Middle and upper part at suspender is provided with roller, and said roller is connected the middle and upper part of suspender, rotates synchronously with suspender; Said adapter sleeve is provided with macropore at last shoulder hole; Its upper surface is connected with the connecting rod lower surface, in the adapter sleeve shoulder hole, is provided with plane bearing, and the last rod end of suspender stretches in the adapter sleeve from adapter sleeve shoulder hole lower end; Pass the plane bearing endoporus, be connected with support plate; Be provided with the roller guide plate of strip in a side of suspender, said roller guide plate is arranged in parallel along the stretched wire pipeline, and its side is parallel with the suspension hook central axis, and the distance L of roller guide plate side and suspension hook central axis is less than roller radius 1～2mm.

The further technical scheme of the utility model is: said roller is connected the middle and upper part of suspender through key.

The utility model compared with prior art has following good effect:

1. simple in structure, be easy to realize.

2. when the stretched wire pipeline is carried, rely on the friction of roller and roller guide plate in hothouse, drive suspender, shell rotation by roller, shell is after getting into hothouse like this, and each surface can evenly receive blowing of air-flow, can make shell evenly dry.

The specific embodiment

Below according to accompanying drawing and combine embodiment that the utility model is described further.

The dry stretched wire pipeline of suspender rotary type fine casting shell shown in accompanying drawing 1, accompanying drawing 2, the accompanying drawing 3; It comprises stretched wire pipeline 1, suspension hook 2, suspender 4, shell 5; Shell 5 is connected suspender 4 lower ends; The improvement that the utility model is done is: suspender 4 is connected on the suspension hook 2 through connecting rod 6, adapter sleeve 7, and the lower end of the upper end of connecting rod 6 and suspension hook 2 is hinged, and the said central axis that is hinged is parallel with the guide rail of suspension hook 2 positions; Be provided with roller 8 in the middle and upper part of suspender 4, roller 8 is connected the middle and upper part of suspender 4, and in the present embodiment, roller 8 is connected the middle and upper part of suspender 4 through key, rotates synchronously with suspender 4; Adapter sleeve 7 is provided with macropore at last shoulder hole; Its upper surface is connected with connecting rod 6 lower surfaces, in adapter sleeve 7 shoulder holes, is provided with plane bearing 10, and the last rod end of suspender 4 stretches in the adapter sleeve 7 from adapter sleeve 7 shoulder hole lower ends; Pass plane bearing 10 endoporus, be connected with support plate 9.Owing to be provided with plane bearing 10, make suspender 4 can realize like a cork for 7 times rotating between suspender 4 and the adapter sleeve 7 at adapter sleeve.

Shown in accompanying drawing 1, accompanying drawing 2, be provided with the roller guide plate 3 of strip in a side of suspender 4, roller guide plate 3 is arranged in parallel along the stretched wire pipeline; Its side is parallel with suspension hook 2 central axis; The distance L of roller guide plate 3 sides and suspension hook 2 central axis is less than roller 8 radiuses 1～2mm, and under self gravitation effects such as suspender 4, shell 5, connecting rod 6 and adapter sleeve 7, roller 8 keeps in touch with roller guide plate 3 all the time like this; When stretched wire pipeline 1 is carried in hothouse; Rely on the friction of roller 8 and roller guide plate 3, drive suspenders 4, shell 5 rotations by roller 8, shell 5 is after getting into hothouse like this; Each surface can evenly receive blowing of air-flow, can make shell evenly dry.
