Abstract
Method for manufacturing an essentially cylindrical receptacle. Because it is difficult to transport such receptacles efficiently, it is proposed initially to manufacture a semifinished article consisting of a sleeve-shaped part provided with a protective layer at least on the inside, which part is readily stackable and, after the very efficient transportation thereof, can be deformed at a second location into a conventional cylindrical holder, with subsequent fitting of at least one base. In order to deform a sleeve-shaped wall into a cylindrical holder, with the fitting of at least the base, considerably less equipment is required than for the manufacture of a completely cylindrical receptacle.
Description
The present invention relates to by claim 1 a kind of method as described in the preamble.
French Patent (FRP) specification 2,343,656 has been narrated a kind of method of making hydrostatic column in two places.
In first place, make the sleeve shaped cone-shaped wall portion particularly that is equipped with a bottom.These conical semi-finished product cover mutually build up a pile, thereby improve conevying efficiency.After all, transport onesize and hydrostatic column intussusception mutually in fact is tantamount to transportation " air ", so cost of transportation is high.
According to the French Patent (FRP) specification, be for further processing in second place then, promptly outwards compacting is the smallest diameter portion at the place, bottom of conical sleeve at least.In this case, must handle especially at bottom section.Last embodiment proposition make the bottom only do distortion slightly also bottom conical sleeve part beveling shape nearby, thereby this part in fact constitutes the part of bottom.
The shortcoming of this method is that the container of making like this is different from the common container that is generally people's acceptance.Therefore, this class container still can't squeeze into the market.And when conical sleeve was deformed into cylindrical sleeve, the junction between bottom and the sleeve shaped wall bottom was subjected to sizable stress, had only the poorly sealed problem in bottom and wall portion that just can reveal in the use afterwards thereby in fact cause.
The objective of the invention is to overcome these shortcomings.
This purpose realizes by the characteristic of claim 1 with said method.According to the present invention, refilling upper bottom portion after the transportation and after sleeve shaped partly is deformed into final size, thereby making container with common outward appearance.Particularly nearby keep common outward appearance in the bottom.And hem seam or weld seam between bottom and the sleeve shaped part are not subjected to distortional stress, and therefore disadvantageous transportation and storage condition do not play influence to final products.At last, according to the present invention, sleeve shaped wall portion carries out surface treatment before transportation.
So just can carry out coating make sleeve shaped wall portion with blank before at least on a surface of blank handles.Plating coating is very favorable before making sleeve shaped wall portion, handles because can carry out coating this moment more on a large scale.Particularly, most of investment be used in paint or the equipment of other coating operation on.They relate to the production efficiency of coating material and must satisfy environment/engine request.Therefore this japanning order both can be used for that the blank that is used for making right cylindrical container, container cover and container bottom was carried out coating and had handled, and can carry out coating to the blank that is used for making above-mentioned sleeve shaped wall portion again and handle.Under this arrangement, can transport to equipment place to the long distance of the blank of handling through such coating ground with these blank making sleeve shaped parts.Obviously, if use welding to make the sleeve shaped wall portion of sealing,, then should not form coating at the free end of blank if coating is an impediment to welding.Stage forms a coating partly in the back.This coating can be a powder coat.
According to one embodiment of the present invention, sleeve shaped wall portion carries out antirust processing before transportation.This is only particularly important through the container of local coating to wall portion.Most of container all is this situation.If the whole youngster of container is coated, then just not necessarily to carry out antirust processing.Like this, just can store sleeve shaped wall portion and they are unlikely immediately and get rusty.
After grip cylindrical wall portion is deformed into the cylinder with net shape, can mix lid.Obviously, also can be unworthy of lid, but make a device,, load onto a demountable lid with this device by means of a for example clamping ring.
Realize with the available any known method of the prior art that is connected between the sleeve shaped wall bottom.
Sleeve shaped wall portion can be conical, also can be cylindrical.If sleeve shaped wall portion is cylindrical, in the transportation preferably the sleeve shaped wall portion some different-diameters be nested together mutually.Make these sleeve shaped wall portions obtain the essentially identical final wall of size portion through in various degree distortion then in second place.In this case, can make different cylindrical wall to the crooked also interlock of the blank of different length on the one hand, on the other hand, can make earlier after the same wall portion of not enough normal size and to make them stand in various degree distortion in first place, thereby the difform sleeve shaped wall portion that makes like this can be set with each other in transit.In this case, the diameter increase of cylindrical wall after the one or many deformation operation preferably is no more than 10%.Surprisingly, we find, if tolerance is done accurately, in certain volume, than the wall of sleeve shaped shown in second embodiment of the invention portion, can transport the columniform sleeve shaped wall portion that is designed to estable of bigger quantity.For can intussusception cone-shaped wall portion and make the unlikely mutual chucking of wall portion of phase intussusception simultaneously and be difficult to and separately can make a circumferential flange.They can be made in the outer or wall of wall.If the bottom is equipped with in cone-shaped wall portion, this circumferential flange must be made in free end outside nearby.If there is not the bottom, this circumferential flange just can be made in the free end inside nearby that has than minor diameter.The advantage of this latter event is that when being deformed into cylindrical wall, this circumferential flange can be eliminated later on.If the free end at wall portion maximum gauge is nearby made the exterior periphery flange, for the purpose of symmetry, be preferably in the circumferential flange that the other end nearby forms a correspondence when being deformed into cylindrical wall afterwards.When cone-shaped wall portion is deformed into cylindrical wall, also can form an interior circumferential flange.Particular importance when this point obtains the container of largest outer dimension at needs, at this moment, people make volume of a container big as far as possible as possible, but enough intensity must be arranged simultaneously, are meant the opposing extruding especially.
According to a preferred embodiment that is used for making interior circumferential flange, had the cone-shaped wall portion distortion of smooth wall originally and formed local interior circumferential flange.
The invention still further relates to the semi-finished product that this method of use is made, i.e. sleeve shaped wall portion.If the minimum diameter of cone-shaped wall portion is particularly littler by 10% than maximum gauge little 20%, then can obtain best sleeve effect.Block mutually when preventing intussusception, cone-shaped wall portion is preferably in the maximum gauge position and has done external flange.Also can form an inner flange at place, minimum diameter position.
The invention still further relates to the container made from above-mentioned sleeve shaped wall portion.At this moment, wall of a container is thick because distortion has change.This change is very little, preferably less than 5%.
The invention still further relates to the device that cone-shaped wall portion is deformed into cylindrical wall or cylindrical wall is deformed into the cylindrical wall of larger diameter.According to the present invention, this device comprises a wall portion support, an expander spare and the device that this expander spare shift-in is shifted out this wall portion.Obviously, after in the expander spare of the off working state immigration wall portion, this expander spare will move into the state that outwards moves, thereby make wall spare be deformed into desired shape.
By the accompanying drawing illustrated embodiment in detail the present invention is described in detail below.In the accompanying drawing:
Fig. 1 is the profile of cone-shaped wall of the present invention portion;
Fig. 2 represents to be nested in mutually together by some semi-finished product of Fig. 1 manufacturing;
Fig. 3 is the profile of another embodiment of cone-shaped wall portion;
Fig. 4 is nested in mutually together for some cone-shaped walls shown in Figure 3 portion;
The container of Fig. 5 for making with Fig. 4 cone-shaped wall portion;
Fig. 6 is nested in together mutually for making columniform some sleeve shaped wall portion, and;
Fig. 7 is for being deformed into cone-shaped wall portion the schematic representation of apparatus of cylindrical wall.
What semi-finished product shown in Figure 1 were total represents with label 1.Fig. 1 represents that also there is a circumferential flange 6 in cone-shaped wall portion and does not have the bottom.
Fig. 2 represents that this cone-shaped wall portion is nested in together mutually.Owing to have circumferential flange, therefore can prevent mutual chucking, because semi-finished product connect mutually by these circumferential flanges.Fig. 2 is clear to be expressed, because mutual intussusception, therefore the volume in the transportation greatly reduces.
Fig. 3 represents another embodiment of cone-shaped wall portion.This moment, this cone-shaped wall portion represented with 16.In this embodiment, the circumferential flange 17 of projection is inwardly arranged, can see clearly especially from Fig. 4, this flange is convenient to the intussusception of cone-shaped wall portion 16.The advantage of this embodiment is that when being deformed into cylindrical wall afterwards, circumferential flange 17 can be eliminated in distortion.Thereby do not see that cylindrical wall is to make from original cone-shaped wall portion.
Fig. 5 represents cone-shaped wall portion is deformed into that cylindrical wall refills upper bottom portion and the container that obtains.This container has nothing different with common container.
Fig. 6 represents to be configured to columniform some sleeve shaped wall portion and is nested in together mutually.These sleeve shaped wall portions represent with 3,4,5,13 and 18.Expression is too much in the distance map between these wall portions, wherein omitted many walls portion with broken line.In fact, the spacing between each wall spare has only several millimeters.
For instance, if 5 cylindrical shroud barrel spares are nested in mutually together, then external diameter is 571.5mm, and internal diameter is 539mm.At this moment, the sleeve shaped wall portion of ragged edge need not remake distortion, and the distortion of the sleeve shaped wall portion of the inside also limited, in above-mentioned example, for the wall thickness of 1mm, the distance between each container is 1.2mm.If select the distance between the adjacent sleeve shaped wall portion as 0.6mm as, wall thickness is elected 1mm as, then can stack 10 jacket casings in above-mentioned scope, and the distortion of minimum sleeve is no more than 6% of final size.From the viewpoint of production technology, under this class close tolerance, operation is fully no problem.Should see, like this,, can in unit volume, transport more sleeve shaped walls portion than the situation of the mutual intussusception of conical sleeve tubular wall spare.After all, under the situation of cone-shaped wall portion intussusception, always might tighten mutually, for fear of chucking, circumferential flange must be arranged, this transfers to have reduced again utilization of space.Using another advantage of cylindrical shroud tubular wall portion is that all wall portions all can be resisted against on the conveying arrangement, for example on the container.And under the situation of the mutual intussusception of cone-shaped wall portion, lowermost sleeve shaped wall portion has to support all other wall portions.
Fig. 7 shows that with label 20 letters one is used for enlarging the device of cone-shaped wall portion 1.This device comprises the support 21 that can place semi-finished product 1 on it.This support 21 can move up and down by means of jack 23.Like this, conical wall part 1 or cylindrical wall 4,5,13 or 18 can move on an expander cone.After inserting wherein, this expander cone outwards moves in the mode shown in the end, thereby forms cylindrical wall, loads onto bottom and lid then, just makes container shown in Figure 5.Simultaneously, before this or afterwards, can form each circumferential flange.Semi-finished product 1 all pass through antirust processing before transportation.Can remove this Rustproofing apparatus then.Obviously, also available any other known pipe expander of the prior art replaces this expander cone.
In the present invention's one exemplary embodiments, we find that for highly being the volumetric standard of 88cm, can use cone-shaped wall portion, the height that about 12 cone-shaped wall portions are nested in a time-out is 230cm.
If use cylindrical shroud tubular wall portion, estable reaches 20 cylindrical sleeves in less than the height of 200cm.This clearlys show can save big quantity space.Be that we find, use cone-shaped wall portion satisfactory under the situation of volumetric standard of 88cm at above-mentioned height, its maximum outside diameter is 585mm, and minimum diameter is 540mm.
Although top usefulness one preferred embodiment has illustrated the present invention, should point out, only otherwise deviate from scope of the present invention, can make all changes.The prior art of all assemblings and container handling all can combine with the present invention, and each claim obviously also is applicable to this combination.
