Description

Rolling mechanism for inner tub for washing machine

The present invention relates to the process equipment of washing machine inner tub, feature is the volume circle process equipment of bucket in the 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, its special feature is: 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.

By such scheme as can be known, 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.

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) links to each other with one of roll through transmission mechanism (7) reductor (4), the end of charging workbench (1) is provided with two rolls (9), (10), two rolls (9), (10) axle core is parallel with workbench (1) 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) below, 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) below is connected with displacement guiding mechanism (3), 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), 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, all the other positions are recessed cylinders, width ratio protruding, recessed cylinder on roll (9), (10) is that the protuberance on 1: 2～5, two rolls (9), (10) is corresponding, and recess is corresponding.Can guarantee that by above scheme interior tubbing sheet (11) volume bowlder is 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) arrives between roll (9), (10); Photoelectric sensor sends signal to cyclelog, cyclelog sends instruction to displacement guiding mechanism (3), make roll (10) rising be close to and tablet (11) is clamped with roll (9), under pressure effect between roll (9), (10), form the circular arc that coincide with roll (9) surface curvature, at this moment roll (10) begins to rotate, the volume circle is finished in tablet (11) feeding gradually, volume circle back tablet (11) under guider (8) guiding.

Referring to Fig. 6,7, roll (9), (10) are at the volume bowlder, its epirelief cylinder is to roll the stone roller application of force along three banded light face zones that tablet (11) is gone up between aperture (11a) and the protuberance (11b), 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 apertures (11a) on the staving, be provided with protuberance (11b) in addition, both distinguish the two sides of projection in tablet (11), it is shaped as the geometry of being convenient to process, as circle, oval, rounded squares etc. are to strengthen its clean result, the recess of setting gone up by corresponding roll (9) and the protuberance (11b) on the tablet (11) matches, protuberance (11b) on tablet during writing that surpasses all the others (11) is contained by the recess on the roll (9), the protruding gauge pressure of roll (9) is ground protuberance (11b) the light face zone on every side of tablet (11), thereby its writing that surpasses all the others is shaped.In addition, on the roll surface of roll (10) little round pool is set, it can correspondence holds the flange of aperture (11a) microprotrusion on the tablet (11), this shows, the layout general layout and the shape of its upper recess and the protuberance of waiting to roll up on the round tablet (11) (11b) 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), the roll surface expanded view of roll (10) arranges that with the aperture (11a) on the tablet (11) general layout is identical, and all the other structures and principle are with embodiment 1.
