Abstract
The utility model relates to a compound plain bumper: shake on including rack, shock dynamo, air spring, the rack that shakes down, its characterized in that: the last rack that shakes shake under and still set up between the rack in the middle of rack and rubber spring, it shakes on, to shake down between rack and the middle rack with the round pin hub connection installs three removable toper support column on the rack, toper support column and the three toper of sand box bottom are supported and litter are matched, two shock dynamo set up both sides and symmetrical arrangement, rotatory in opposite directions at the last rack that shakes. Compared with the prior art, the utility model discloses can reduce the vibration to the basis, can guarantee again has certain vibrational force to the sand box, and required depth of foundation is shallow, and installation and debugging simultaneously are convenient, and task load is few.
Description
Technical field
The utility model relates to Technology of EPC field, is specifically related to a kind of compound plain bumper.
Background technology
Plain bumper is indispensable equipment during lost foam casting is produced, the plain bumper used in existing production generally comprise the stand that shakes, air spring, under to shake stand three parts, on to shake six vibrating motors stand being fixed with 4 clamping cylinders and arranging by an orientation, cylinder is used for the sandbox that is fixedly clamped, the exciting force of vibrating motor makes sandbox produce the vibration of X, Y, Z three-dimensional, air spring is used for connecting lower stage, lifting upper table surface and sandbox after inflation, sandbox is de-orbited, reduces the vibration to basis simultaneously.Under the stand that shakes be used for fixing air spring, the exciting force of whole system is passed to basis uniformly simultaneously.This structure existence foundation is dark, installation and debugging relative complex, noise large and can only produce the drawback of vibration in three directions.
Summary of the invention
For the above-mentioned defect that technology exists, the utility model provides a kind of compound plain bumper: comprise the stand 2 that shakes, vibration motor 3, air spring 7, under to shake stand 8, it is characterized in that: upper shake stand 2 and under shake between stand 8 middle stand 5 and rubber spring 4 be also set, under shake between stand 8 and middle stand 5 with pinned connection, on shake on stand three removable taper support posts 1 be installed, taper support post 1 matches with the taper support nest of three bottom sandbox; Two vibration motors 3 be arranged on the both sides of the stand 2 that shakes and be arranged symmetrically with, opposite direction rotating.Taper support post matches with the taper support nest of three bottom sandbox, sandbox is made to be quick condition, exciting force can be made effectively to pass to sandbox, the noise of vibration can be made again effectively to absorb, solve the noise problem brought after plain bumper clamping cylinder wearing and tearing in the past loosen.Two vibrating motors be arranged symmetrically with are primary oscillation source of plain bumper, two motor opposite direction rotatings, sandbox can be made to produce the acceleration of 1-2g, make sand density reach more than 1.6.The exciting force up and down that vibrating motor produces, through the superposition of rubber spring and air spring, makes the circular vibration shaken in stand generation Z-direction and horizontal plane.It is the characteristic of this plain bumper that the superposing of rubber spring, middle stand and air spring is designed, this design can reduce the vibration to basis, can ensure again have certain vibration force to sandbox, molding sand can be made effectively to be filled into the inner chamber of model, ensure that fillibility and compactibility; This kind of structure is shaken below stand and do not have vibrating motor (vibrating motor is only in the upper stand both sides that shake), therefore depth of foundation is shallow, and installation and debugging are simultaneously convenient, and task amount is few.Under to shake between stand and middle stand with pinned connection, can be used to the stroke adjusting air spring
.
Further, shake under between stand 8 and middle stand 5 and install stopping means 6 additional.
Further, three support columns 1 on the table top of the upper stand 2 that shakes by triangular arrangement.
Further, three support columns 1 are arranged by equilateral triangle on the table top of the upper stand 2 that shakes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
A kind of compound plain bumper: compound plain bumper, comprise the stand 2 that shakes, vibration motor 3, air spring 7, under to shake stand 8, upper shake stand 2 and under shake between stand 8 middle stand 5 and rubber spring 4 be also set, under shake between stand 8 and middle stand 5 with pinned connection, on shake on stand three removable taper support posts 1 be installed, taper support post 1 matches with the taper support nest of three bottom sandbox; Two vibration motors 3 be arranged on the both sides of the stand 2 that shakes and be arranged symmetrically with, opposite direction rotating.Under shake between stand 8 and middle stand 5 and install stopping means 6 additional.Three support columns 1 are arranged by equilateral triangle on the table top of the upper stand 2 that shakes.
Compound plain bumper shake on adopting stand, rubber spring, middle stand, air spring and under to shake horse structure.On shake stand adopt Plate Welding, the processing technology of post-weld annealed, effectively prevent distortion and the cracking of table top, on shake on stand three removable support columns and two vibrating motors be installed, support column matches with the supporting clutch of three bottom sandbox, sandbox is made to be quick condition, three support columns are arranged by certain angle on the upper table top that shakes, the cone angle of support column upper end and the design of material can make exciting force effectively pass to sandbox, the noise of vibration can be made again effectively to absorb, solve the noise problem brought after plain bumper clamping cylinder wearing and tearing in the past loosen.Two vibrating motors be arranged symmetrically with are primary oscillation source of plain bumper, two motor opposite direction rotatings, sandbox can be made to produce the acceleration of 1-2g, make sand density reach more than 1.6.The exciting force up and down that vibrating motor produces, through the superposition of rubber spring and air spring, makes the circular vibration shaken in stand generation Z-direction and horizontal plane.It is the characteristic of this plain bumper that the superposing of rubber spring, middle stand and air spring is designed, this design can reduce the vibration to basis, can ensure again have certain vibration force to sandbox, molding sand can be made effectively to be filled into the inner chamber of model, ensure that fillibility and compactibility; This kind of structure is shaken below stand and do not have vibrating motor, vibrating motor is only in the upper stand both sides that shake, and therefore depth of foundation is shallow, and installation and debugging are simultaneously convenient, and task amount is few.Under to shake between stand and middle stand with pinned connection, can be used to the stroke adjusting air spring.
