Description
The present invention relates to a kind of cylinder and production technology thereof of washing machine.
Tumbling-box washing machine can be divided into muzzle-loading and roof-mounted two kinds, though the washing machine washing principle of these two kinds of patterns is identical, the structure of cylinder is completely different.At present, the cylinder of homemade front-loading washing machine adopts the polishing stainless steel plate through blanking, punching, roll-forming, it is installed in the washing machine is by the outstanding axle supporting of a list, only assemble by cylindrical shell and one sealing cover and a perforate cover, though moulding process is simple, but its strength and stiffness are poor, outstanding axle beam barrel lid particularly is housed, in heavy load, under the high rotating speed, be easy to generate the flexible deformation, influence concentricity, in moving the commentaries on classics, cause vibration easily, and the sealing property at perforate cover place is difficult to guarantee, influences clean result and washing machine performance, has shortened the service life of whole washing machine.
The object of the present invention is to provide a kind of strength and stiffness good, running is difficult for producing vibration under high rotating speed, heavy load, does not also have flexible deformation's top assembled tub of washing machine and production technology thereof.
Below in conjunction with drawings and Examples the present invention is described in detail.
Fig. 1 is the profilograph of top assembled tub of washing machine.
Fig. 2 is the left view of top assembled tub of washing machine.
1-cylindrical shell 2-doorframe 3-backing plate 4-spring 5-cover 6-arc-shaped door 7-knocker
The top assembled tub of washing machine profile is a right cylinder, and appearance and size is 0 440 * 270mm; Cylinder is made up of cylindrical shell (1), doorframe (2), backing plate (3), spring (4), cover (5), arc-shaped door (6) and knocker (7). Cylindrical shell (1) forms 360 ° the face of cylinder with doorframe (2), two ends form integral body by two sealing covers (5) and its crimping, have two arc-shaped doors (6), arc-shaped door (6) to tie on doorframe (2) through backing plate (3) and spring (4) hinge on the doorframe (2), two arc-shaped doors (6) are by knocker (7) locking in the running.
The production technology of top assembled tub of washing machine is as follows:
One, at first finishes the cold stamping shaped of following each part
1. cylindrical shell: cylindrical shell (1) is made by the thick 1Cr13 corrosion resistant plate of 0.6mm, be furnished with totally 1532 of the circular apertures of diameter 4mm on the barrel wall, these apertures are divided into two by three lifting muscle on the barrel, distance between Kong Yukong is 5mm, three lifting muscle are the cylinder boss of long 205mm, wide 65mm, cylinder boss exceeds cylinder inboard wall 20mm, and two ends are sphere.The aperture of cylindrical shell is by the outer punching out of introversion, and the lifting muscle behind the punching of cylindrical shell process, die mould, the drawing and forming, launches the long 1044mm that is by the deep-drawing technique moulding, and wide is 280mm, and the fan-shaped central angle of cylindrical shell is 265 °, and this part will be round as a ball with doorframe (2) undercut.
2. doorframe: doorframe (2) is made by the thick 1Cr13 corrosion resistant plate of 0.6mm, it also is a department of cylinder cylinder side surface, and fan-shaped central angle is 95 °, opening along drum shaft to the hole that 12 zero 5.3mm are arranged, these holes are in order to rivet with gemel backing plate (3), hinged two arc-shaped doors of backing plate.Doorframe is by launching long 382mm, and wide 280mm blanking after punching, opening, compression moulding, rolls into radius 220mm, and central angle is 95 ° a secter pat, and this part will be round as a ball with cylindrical shell (1) undercut.
3. cover: two covers (5) are two bottom surfaces of cylinder cylinder, are to be made by the thick 1Cr13 corrosion resistant plate of 0.6mm.The cover center is provided with the segment in order to the running in bearings supporting, and the segment radius is 95mm, and high 14mm also has on the cover in order to improve the rib of cylinder intensity.First pull and stretch segment behind cover (5) blanking and punching press rib, cylindrical leave the undercut surplus with cylindrical shell (1), doorframe (2) assembling.
4. arc-shaped door: two arc-shaped doors (6) all are to be made by the thick corrosion resistant plate of 0.8mm, their fan-shaped central angle is 37 ° 30 ', the aperture that punching out is from inside to outside all arranged on the door wall, hole diameter is 4mm, quantity is 20～26, the door on the hinge type crimping is arranged, the door through blanking, punching, die mould, the postforming of flexure hinge limit.
5. backing plate: backing plate (3) is made by the 1Cr13 corrosion resistant plate, appearance and size is 210 * 25mm, it is the aperture of 5.5mm that 6 diameters are arranged on it, and have a hinge crimping, the aperture that is 5.5mm by 6 diameters is positioned at backing plate riveting formulation on the doorframe (2), backing plate by the location connects two arc-shaped doors with the hinge form, and it is through blanking, punching press, flexure hinge limit aftershaping.
6. knocker: knocker (7) is made by the 1Cr13 corrosion resistant plate, and its appearance and size is 80 * 18mm, and first punching press profile then adopts the specific purpose tool crimping.
Two, carry out the moulding of partial groups component
Cylinder will be finished the partial groups synthesis type of following three parts after finishing each part cold stamping shaped:
1. the round as a ball moulding of undercut of cylindrical shell (1) and doorframe (2);
2. the assembled formation of arc-shaped door (6), knocker (7), spring (4);
3. backing plate (3) is located with the riveted joint of barrel.
Three, carry out the assembled formation of cylindrical shell and two covers
Adopt the senior frock process equipment of cylinder integral assembling moulding, turn down the undercut moulding several times.
Four, finishing combination arc-shaped door (6) adorns with the accent of doorframe (2)
After finishing above technical process, the cylinder moulding.
The present invention compares with the muzzle-loading cylinder, has the following advantages: 1. double supporting structure; 2. cylindrical shell concentricity height; 3. long service life. Because these cylinder two ends are the sealing cover, at two covers the ball bearing supporting is housed respectively, two shaft concentricity height, such cylinder not only strength and stiffness is good, two fulcrums are coaxial, and running is difficult for producing vibration under high rotating speed, heavy load, does not also have the flexible deformation, also need not the special disposal sealing problem, so prolonged the service life of whole washing machine.
