Description

Rolling mechanism for inner tub for washing machine

The present invention relates to the volume circle process equipment of bucket in the process equipment of washing machine inner tub, particularly metal.

General steel rolling mill is when rolling major diameter (＞Φ 300mm) bucket, usually adopt three rollings volume equipment, this equipment plastic force is big, but it is not high only to be suitable for required precision, the sheet material volume circle of thickness δ＞2mm is shaped, because roll is the rigidity light face of cylinder, therefore, it only is suitable for rolling of optic panel material, (the tablet processing volume circle of thickness δ=0.6mm) is unsuitable to this equipment, and it is impossible at all especially the tablet of processing too small hole flanging and convex-concave shape position being rolled up the circle processing for bucket in the stainless steel that resembles on the washing machine.

The object of the present invention is to provide a kind of thin tablet that is suitable for processing small holes and convex-concave shape position to roll up round equipment.

The technical solution used in the present invention is: rolling mechanism for inner tub for washing machine, it comprises frame and is provided with the charging workbench, electrical control cabinet, the axle head of motor links to each other with one of roll through the transmission mechanism transition, it is characterized in that: the end of charging workbench is provided with two rolls, the axle core of two rolls is parallel to workbench and the roller spacing is adjustable, and roll is that the rigid roller and the body of roll are concavo-convex, and the surface of another roll is the soft roller of elasticity.

As shown from the above technical solution, tablet along table feed to clamped between the roll, the dancer rools spacing further compresses tablet, tablet is pressed and is deformed along the rigidity roller surface, protuberance on the tablet is just corresponding to the recess that is provided with on the rigidity roll and by its containing, therefore, protuberance on the rigidity roll is pressed the optical plane position of grinding on the tablet, it is deformed, occur corresponding cancave cambered surface after the areal deformation of elasticity pressure release surface roll, when actuating unit drives roll rotation, be curled while tablet then advances, this shows that the present invention can guarantee to be provided with the volume circle processing of the tablet of protuberance and aperture.

The present invention is described in further detail below in conjunction with accompanying drawing.

Embodiment 1

Referring to Fig. 1,3,4, frame 2 is provided with charging workbench 1, workbench 1 below is provided with highly to be regulated and fixed mechanism, electrical control cabinet 6, the axle head of motor 5 is through transmission mechanism 7, reductor 4 links to each other with one of roll, the end of charging workbench 1 is provided with two

rolls

9,10, two

rolls

9,10 axle core and workbench 1 are parallel and the roller spacing is adjustable,

roll

9,10 the body of roll is concavo-convex cylinder, wherein roll 9 is a rigid roller, the projection face of roll 10 is the soft roller of elasticity with certain intensity, roll 10 is positioned at roll 9 belows, two

rolls

9,10 discharge end is provided with discharging guider 8, in fact guider 8 is a roll body free to rotate, it and two

rolls

9,10 also answer keeping parallelism, roll 10 is a drive roll, be that roll 10 links to each other with actuating unit, roll 10 belows are connected with displacement guiding mechanism 3, and this mechanism can adopt hydraulic pressure, pneumatic or mechanical device is realized, displacement guiding mechanism 3 reaches the purpose of supercharging volume circle by the process that changes two roll roller spacings, displacement guiding mechanism 3 links to each other with the two axial ends axle bed of roll 9, and therefore, the supporting base of roll 9 must be the supporting base of an activity, by shown in Figure 1, roll 9 is limited in the guide groove of its two axial ends and can goes up, move down.

Referring to Fig. 1,5, the projection face on the

roll

9,10 has several, generally selects 3～5 to be advisable, and all the other positions are recessed cylinders, and the width protruding, recessed cylinder on the

roll

9,10 is more corresponding than the protuberance on 1: 2～5, two

rolls

9,10, and recess is corresponding.Can guarantee that by above scheme interior tubbing sheet 11 volume bowlders are stressed evenly in order to avoid the negative effect that warping phenomenon brings occurs, can guarantee again that on the other hand tablet 11 has enough areas to lay boss to guarantee clean result.

The course of work of volume round belting: opening power, after starting knob, device is in duty, when tablet 11 reaches between the

roll

9,10, photoelectric sensor sends signal to cyclelog, cyclelog sends instruction to displacement guiding mechanism 3, roll 10 is risen be close to roll 9 and tablet 11 is clamped, under 9,10 pressure effects of roll, form the circular arc that coincide with roll 9 surface curvatures, at this moment roll 10 begins to rotate, tablet 11 feeding gradually, volume circle back tablet 11 is finished the volume circle under guider 8 guiding.

Referring to Fig. 6,7,

roll

9,10 is at the volume bowlder, and its epirelief cylinder is that three banded light face zones between aperture 11a and the protuberance 11b are rolled and ground the application of force on the tablet 11, thereby can not damage set aperture 11a and protuberance 11b, and can finish volume circle process smoothly.

Embodiment 2

Referring to Fig. 2, the shape at the concavo-convex position on the roll surface of

roll

9,10 is different with embodiment 1 with the layout general layout.Referring to Fig. 6,7, to washing machine inner tub, evenly be furnished with many aperture 11a on the staving, also be provided with protuberance 11b in addition, both distinguish the two sides of projection at tablet 11, it is shaped as the geometry of being convenient to process, as circle, ellipse, rounded square etc. to strengthen its clean result, recess that is provided with on the corresponding roll 9 and the protuberance 11b on the tablet 11 match, protuberance 11b during writing that surpasses all the others on the tablet 11 is contained by the recess on the roll 9, the protuberance of roll 9 is pressed the light face zone around the protuberance 11b that grinds tablet 11, thereby its writing that surpasses all the others is shaped.In addition, little round pool is set on the roll surface of roll 10, it can corresponding hold the flange of the aperture 11a microprotrusion on the tablet 11, this shows, the layout general layout and the shape of its upper recess and the protuberance 11b that waits to roll up on the round tablet 11 matched when the roll surface of roll 9 launched, small rut on the roll 10 just in time holds the flange of the microprotrusion of the aperture 11a on the tablet 11, and the aperture 11a on the roll surface expanded view of roll 10 and the tablet 11 arranges that general layout is identical, and all the other structures and principle are with embodiment 1.
