Abstract
After the selected stainless steel plate is punched and features that raised part and hem is manufactured in pressure equipment, the rolled and buckled barrel and the bottom are buckled to constitute the dewatering tub. Afternately, after punched, the rolled and buckled barrel is manufactured to produce the raised part before being buckled with the bottom to form the dewatering tub. The present invention has the obvious advantages of less manufacture steps, low investment in equipment and good versatility, and these favours lowering product cost and upgrade.
Description
The present invention relates to the shaping processing technology of stainless steel dewatering tub for washing machine.
Make the washing machine of dehydration barrel with working of plastics, staving shape injection mold and the equipment that depends on designed use.Because the special performance that stainless steel has, now successively adopted by washing machine producer, it is comparatively general to use stainless steel material to make the dehydration washtub on roller washing machine, the roller washing machine manufacturer gondola production line of most introduction is carried out the processing of stainless steel bucket, and its procedure comprises following order: selection → punching and blanking → volume circle → spot welding location and snapping (or welding) → pressed expansion type → connect with the fixing fastening that reaches of bucket end spot welding.The major defect that this processing technology exists in concrete enforcement is that round the fastening when connecting of volume needs fastening place spot welding assist location, in addition, staving fastened with the bucket end also needs the spot welding assist location when connecting, this process needs twice spot welding assist location, manufacturing procedure is many and complicated, and equipment investment is big.Volume circle back directly adopts welding manner to connect, and then needs task equipment, equally also can increase production cost of products.
The objective of the invention is to simplify the processing technology of stainless steel dewatering tub for washing machine, thereby reduce production costs.
One of the technical solution used in the present invention is: the manufacture method of stainless steel dewatering tub for washing machine, selected stainless steel bucket sheet material, it is characterized in that: staving sheet material is carried out punching and blanking by design specification, adopt press device to suppress concavo-convex position and hole flanging afterwards, and flange is carried out on the long limit of sheet material handle, the place fastens connection through the round crimp rear port, the circular staving and the bucket end that is rolled into is fastened mutually be connected into dehydration barrel.
The another kind of technical scheme that the present invention adopts is: the manufacture method of stainless steel dewatering tub for washing machine, the at first selected stainless steel materials that conforms to designing requirement, staving sheet material is carried out punching and blanking by design specification, rolling up circle handles afterwards with the connection of interface fastening, the round tank body and function press device of Xing Chenging carries out the rise type and the hole flanging processing at concavo-convex position thus, and upper and lower edge outward flanging become flange, the circular staving behind the type that rises becomes one with the mutual snapping in the bucket end.
According to the present invention, the assist location operation that does not need spot welding and so in the processing technology of stainless steel dewatering tub, process is simplified, thereby great deal of investment and operation process have been saved, make the processing cost of stainless steel dewatering tub significantly reduce, in addition, processing technology provided by the invention, have good versatility, be convenient to the update of product.

Embodiment 1
As shown in Figure 1, the manufacture method of stainless steel dewatering tub for washing machine, at first selected stainless steel bucket sheet material (10), staving sheet material (10) is carried out punching and blanking by design specification, aperture on it (11) is the usefulness of water supply and sewage circulation, the sheet material shape as shown in Figure 2, adopt press device to suppress relief members (12) on it afterwards, (13), and flange is carried out on two long limits of sheet material handle, as Fig. 3,4, shown in 5, afterwards through rolling up shape such as the Fig. 6 after justifying, the shape of its interface such as Fig. 7, fastening process such as Fig. 8, shown in 9, the flange that wherein at first carries out interface fastens connection again, structure such as Figure 10 of being shaped, 11, shown in 12, the dehydration after snapping is shaped mutually with the bucket end (20) with circular staving (10) is barrel-shaped as Figure 13.
As shown in Figure 3, concavo-convex position (12), (13) and hole (11) are corresponding concentrates in upper and lower three belt-like zones, the zone that forms thus between the doublet among Fig. 4 is banded light face, the specific arrangements of this concavo-convex position (12), (13) and hole (11) is in order to reserve banded light face so that match with roll on the volume circle equipment, it is step-like to be that roll also is designed to, the working face of roll was successfully ground from above-mentioned banded light face, thereby guarantee to roll up finishing of sired results preface.
Staving among Figure 13 (10) and the bucket end (20) are fastened and to be connected by the roller press flange that rolls; the general work process of roller press is at first (20) at the bottom of the bucket and staving (10) to be put together; rise mold mechanism by in the bucket radially with staving (10) with the bucket end (a 20) appropriate tensioner; and drive its rotation; the idler wheel mechanism of staving (10) outer setting radially moves the flange snapping place that is pressed against staving (10); and turn down snap action, thereby staving (10) and the bucket end (20) are combined as a whole.
Embodiment 2
Present embodiment and embodiment 1 there is no in essence different, just arranging of concavo-convex position (12), (13) and hole (11) do not required that strictness is distributed in three belt-like zones, in other words and do not require and on the sheet material of staving (10), reserve corresponding banded light face, surface design for the roll on the volume circle equipment becomes concavo-convex, shape after it launches and the same staving of layout (10) are gone up jog position (12), (13) and hole (11) match, and make can guarantee the sheet material that is suppressed with concavo-convex position (12), (13) and hole (11) is rolled up circle processing.
Embodiment 3
Carry out punching and blanking by layout shown in Figure 3, roll up circle afterwards and fasten, shown in Figure 16～22, the staving (10) after being shaped is processed concavo-convex position (12), (13) with the type equipment that rises, shape is finished staving (10) by roller press at last and is connected with the fastening of the bucket end (20) as shown in figure 10.The type equipment that rises in the present embodiment is comparatively complicated, and the processing cost of its inside and outside mould that rises is high slightly, but the circle of the volume in this method equipment topping roll is cylindrical roll body, and its cost is lower.
Said stainless steel is not limited to the stainless steel of indication on the metallography among the present invention, have antiseptic and rustproof characteristic as material, and have certain intensity and ductility, all be suitable for adopting the present invention, as the aluminium alloy with certain ductility is made bucket end staving and plastics are made bucket during the end, and the present invention is suitable equally.
