The specific embodiment
With reference to figure 5, there is shown an embodiment of improved automobile bodies assembly 161, the compartment assembly that specifically is used for light truck wherein adopts roll forming 1/4th plates 162 (being the end/side plate of integral type) that improved technology is made according to the present invention.Only show the end/side plate 162 on the right among Fig. 5, for illustrate clear for the purpose of, the end/side plate on the left side is removed, but will be appreciated that, in general the end/the side plate on the left side is the mirror image of the right end/side plate basically.
In compartment assembly 161, base plate 122 is made of a plurality of bottom parts, comprises main central floor panel part 131, and it extends longitudinally on whole length of base plate, but width is generally just taken turns the distance size between the cabin, thereby central floor panel part 131 is rectangle substantially in planar view.The both sides of base plate are finished by side edge bottom plate portion 131A again, each side edge bottom plate portion 131A mainly is made of forward and backward side floor section 132 and 133, they lay respectively at the front and back of wheel cabin opening 163, and (sidewardly) extension towards central floor panel part 131 along side direction from side plate or sidewall 127.
In this structural form of compartment assembly, side plate 127 and bottom parts 131A make as the single-piece roll forming plate 162 of an integral type, and it is known as the end/side plate of 1/4th plates or integral type here.In general the independently single-piece wheel cabin case 128 that is the single-piece punching press is fixed on the plate 162 with disk wheel cabin opening 163.In the present invention, the inside of this single plate 162 preferably is provided with shelf part 136, and it just in time is positioned at the top of wheel cabin opening 163, but below the top flute profile is strengthened rail 139.Shelf part 136 constitutes a roughly straight diapire 137, it be up and at the length upper edge of side plate 127 horizontal-extending, thereby can converge with the similar horizontal shelf that preferably is arranged in the header board 126 effectively.
For header board 126, it is the single-piece roll forming plate of an integral type preferably.
With regard to central floor panel 131, it preferably with sheet steel longitudinally roll forming become the single-piece of an integral type.The transversal surface of floor piece 131 constitutes by many almost parallels and along laterally spaced tongue or rib 141 (Fig. 6), is replacing middle trench between them or is caving in 142.
The upright side plate 127 that is made of the roll forming plate 162 of integral type is with the foil roll forming, thereby forming many strengthening ribs 135 therein, they extend longitudinally with the horizontal rack structure 136 and the groove shape head track 139 that are positioned at opening top, wheel cabin.The side edge bottom plate portion 131A that is made of the plate 162 of integral type also is a roll forming longitudinally, thereby preferably be provided with one or more outstanding strengthening rib or grooves 154 up, but also be provided with the outstanding fastening flange 156 in location that extends along its free edge downwards along its longitudinal extension.
With reference to figure 7, schematically show a kind of economy and manufacturing process efficiently among the figure, be used for side by side relationship two 1/4th plates 162 of roll forming simultaneously, these plates are along the vertical order roll forming of thin plate.
In this process, basically be to be drawn out the continuous roller 51 of wide flat metal (being steel) thin plate 54 on being bearing in support 53, then thin plate 54 is admitted to grooving machine 57, be used to produce the notch 58 of paired arrangement in this embodiment, they are inwardly outstanding from the thin plate both sides with predetermined spacing along thin plate.The thin plate 54 of having opened notch then enters in the milling train (rollingmill) 61, through some different rolling stages straight foil is reshaped there, make thin plate 62 distortion leave milling train 61 and have as shown in Figure 8 transversal surface, so finally can produce double-type 1/4th roughly the same or symmetrical plates with the spacing that limits along thin plate.
Straight metallic thin plate 54 in milling train 61 roll forming for as shown in Figure 8 shape to form a pair of adjacent and identical interior plate portion or bottom parts 131A, they laterally connect thereby are positioned at the both sides of longitudinal centerline or longitudinal plane of symmetry 113.These bottom parts 131A is connected to identical outer plate portion of shape or plate portion 127 again.Each plate portion 127 has along the strengthening rib 135 of the roll forming of roll forming thin plate longitudinal extension, shelf 137 and outer rail (being head track) 139.Bottom parts 131A and plate portion 127 remain roughly straight relation each other, and datum line 166 is positions that follow-up bending operation will take place.
Shown among this embodiment, adjacent bottom parts 131A links to each other by center rib or groove 181 (Fig. 9), its width of being determined by roof 182 is more a lot of greatly than the width of last adjacent rib of bottom parts 131A or groove 154.The width that central groove 181 is this have been increased makes it possible to line of centers 113 longitudinally to carry out follow-up vertically cut apart or cutting off, and the cut edge part at these line of centers 113 places is bent downwardly subsequently to form basically limit portion flange 156 as shown in phantom in Figure 9.These limit portion flanges 156 are associated with the rib or the groove 155 of gained, and described rib or groove 155 be the half-breadth groove normally, in order to cooperate with the half-breadth groove 146 that extends along roll forming central base sheet 131 edges, to form the structure shown in Fig. 6.This groove 146 also forms a limit portion flange 148, so flange 148 and 156 pairs are supported and can weld together.
The continuous thin plate 62 of roll forming is admitted in shutoff device 64 moulds like flying (flying die) afterwards leaving milling train 61 (Fig. 7), be out of shape there thin plate roughly along the line consistent with paired notch 58 by transverse cuts, to form the roll forming slab 162F that has cut off or cut.Slab 162F then is sent to bench board 171, and line of centers 113 is along its length vertically cut there, is two slab spare 162F so slab 162f is cut into, and they are identical but with the adjacent layout of mirror side direction basically.The slab spare 162F that has cut then is transported to and is shaped or rolling station 172, and its longitudinal edge promptly is out of shape gradually by the edge that the line of centers slot produces, forming the limit portion flange 156 of downward upset.The slab spare that has limit portion flange is then delivered to hole forming station 173 separately or together such as in the bicker, hole forming station 173 can be one by one or is acted on simultaneously on one or two slab spare 162F ', and at central formation wheel cabin opening 163, but also can form other any desired opening or notch.In general this shaping or punching press platform 173 can also carry out deburring to the end edge of slab, and the fastening flange in any desired location on wheel cabin opening and/or the slab end edge is formed or cuts.Slab 162F ' then is sent to one or more shaping platforms 174 one by one or simultaneously, there the fastening flange in the location of slab is carried out suitable reshaping such as bending or cold-working, makes flange laterally projecting with respect to corresponding plate portion.The formed slab that wherein has opening and flange then is transported to crooked platform 175 such as in bending or the wing press, make ground plate portion 131A and the roughly relative bending of 166 generations of plate portion 127, thereby make these parts so that roughly orthogonal relation is outstanding around the position.Then with roll forming and be that L shaped plate 162 is discharged from compression machine 175, handle to become the part that car floor are constructed with being connected assembling required planform then.
In the above in the process of being introduced, slab 162F ' preferably just was cut off and formed limit portion flange 156 in the above before punching press wheel cabin opening 163, because limit portion flange 156 can provide sizable booster action along the longitudinal edge of bottom parts, and this is very essential, because the wheel cabin opening 163 that punching press is come out extends laterally between its edge 164 and 165 (Fig. 5), wherein the position at edge 165 is tightly adjacent with this one side portion flange 156.
As a kind of improved form to roll forming section form shown in Fig. 8-9, the central groove 181 that has enlarged can substitute with the narrower but darker central groove 183 of a counter-rotating, as shown in Figure 10.The sidewall of groove 183 utilizes this structural form, in fact can longitudinally cut the roll forming slab, so can play the effect of the limit portion flange 156 of slab 162F ' effectively by the diapire 184 that removes groove 183.Diapire 184 can be removed with two cut-off wheels, and it can realize vertically cutting apart in the downstream of milling train 61, the upstream of shutoff device 64.Perhaps, diapire 184 can be removed by punching operation, and punch operation can be carried out at shaping platform 173, promptly when stamping out wheel cabin opening 163 diapire 184 punching presses is fallen.
For compartment assembly 161 shown in Figure 5, all crucial plates comprise that header board, 1/4th plates and central base sheet in fact can roll formings, thereby have economy aspect material usage, finished product compartment assembly weight, member manufacturing and the compartment assembling.Wheel cabin case 128 is unique main punch components, and these parts are welded on around the edge of wheel cabin opening 163 in a conventional manner, wherein take turns cabin opening 163 be arranged on the single-piece of integral type of roll forming at the bottom of/side plate 162 in.
For the roll forming plate of compartment assembly according to the present invention, will be appreciated that, the straight steel-sheet width that provides with web form corresponds essentially to the flattening width of paired production board, therefore in general needn't carry out deburring, thereby realize the minimum consumption of light sheet material thin plate or production board.In addition, the roll forming of crucial plate is avoided effectively or has been reduced the stretching (be reduced thickness) of thin plate in forming process at least greatly, therefore can use the thin steel plate of original depth to form plate, especially compare all the more soly with pressed sheet, and the whole thickness of last resulting roll forming plate is uniform basically.Can make the finished weight of plate reduce to minimum like this, reduce material cost, and can simplify desired machining tool greatly, make the use of machining tool have greater flexibility simultaneously with remarkable reduction facility installing cost.Actual design for milling train or roll forming machine, will be appreciated that the conventional art application that the roll forming machine designing institute relates to is that those of ordinary skill is known in the roll forming field, so we think it unnecessary roll forming machine is made further explanation and description.
With reference now to Figure 11-14,, there is shown compartment assembly 210 in accordance with another embodiment of the present invention.Many preferable configuration characteristics of being introduced above compartment assembly 210 has, but it can provide improved integral structure performance and economic benefit, because it can constitute base plate and left and right inner side wall plate in a single-piece side with two integral types/floor member assembling.Two plates are preferably used metal (being steel) thin plate roll forming, so just only need a kind of roll forming plate shape just passable.Then to the plate of roll forming carry out the post forming operation such as punching or compression molding to produce left and right plate, they can be assembled to constitute the floor and relative side plate of compartment assembly.
Compartment assembly 210 (Figure 11) is included in the floor that extends laterally between the relative upstanding side wallboard 212 or 211, two sidewall panelinies of base plate 212 because left and right configuration, in general mirror image each other substantially.In this structural form, floor 211 and sidewall paneling 212 are that single-piece side/floor member 215R and the 215L by two preformed integral types constitutes, they constitute the left and right side of compartment assembly respectively in the entire longitudinal length of compartment assembly, and preformed board 215R and 215L are except roughly the same the mirror image (being left and right plate) each other basically.
Right panel spare 215R shown in Figure 13 comprises bottom parts 216, and its turn of bilge by longitudinal extension or bight 218 link to each other with upright plate portion 217, so these two parts 216 form L shaped transversal surface with 217 with vertical substantially relation extension.When relative plate 215R and 215L were positioned in some traditional crossbeams (representing wherein with 219) and go up, bottom parts 216 was such as being fixed on the crossbeam by welding.
In the above in this preferred embodiment of being introduced, be half of overall width on floor 211 basically by the overall width of the bottom parts 216 that limits between limit portion flange 224 and the corner 218.
Referring now to the diagram of circuit among Figure 15-16, introduce in order to the plate 215R of formation compartment assembly 210 and the selection process method of 215L.
Basically be that continuous straight metal (being steel) thin plate 241 is delivered to grooving apparatus 242 from coiling, and form slit or notch 243 along thin plate with the predetermined distance that corresponds essentially to plate 215 length there, notch 243 from the thin plate edge 244 inwardly incision and its length enough in order to form head track 231.The notch in order to formation limit portion flange 224 also can be left in another edge of thin plate, but this there is no need usually.The thin plate 241 of having opened notch then is admitted in the multi-stage rolling mill 247 thin plate is out of shape gradually, makes the thin plate that leaves milling train have transverse shape as shown in Figure 12.State after this distortion, thin plate have rail 231 that extends along an one edge and the limit portion flange 224 that extends along another relative edge.
Strained continuous thin plate then is transported to and cuts off punching machine 248, aims at each notch 243 there thin plate is vertically cut off, thereby form straight but strained independently plate 215.
Then the identical plate to roll forming carries out the post forming control step, to form left plate and right panel, as shown in Figure 16.
More particularly, plate then is admitted to compression machine (press) 251R and 251L, in order to form wheel cabin opening 223 in plate.Because this opening is not positioned at the mid point of floor length direction usually, so must form different left and right plates.Compression machine 251R, 251L can also carry out other deburring operation usually, such as end edge at plate, and at end and opening part formation holding flange.Compression machine 251R, 251L can be separately or combine.
Then act on the plate, to form holding flange with follow-up shaping dies or compression machine 252R, 252L.
The plate that comes out from machine 252R, 252L then is sent to compression machine (being wing press) 253R, 253L, carries out bending or scrolling there forming corner 218, then floor and plate portion 216,217 vertical protrude L shaped.Plate 215R that is processed into and 215L discharge from compression machine 253R, 253L then.
Then double-type plate 215R can be arranged on a plurality of parallel crossbeams with relativeness with 215L, make relative limit portion flange 224 basically to supporting, as shown in Figure 11.The limit portion flange 224 that supports is welded together, and the bottom parts of plate is soldered or be fixed on the crossbeam with other method.In fact the limit portion flange 224 that supports is extended along the longitudinal centerline on floor.Limit portion flange 224 can form recess in the position corresponding to crossbeam, and perhaps crossbeam can be provided with the gap notch to hold limit portion flange.
For the bottom deck assembly that constitutes as stated above, the front of base plate can be sealed with any traditional header board, but preferably uses the header board of roll forming.
According to this embodiment of the present invention (Figure 11-14), plate 215R, 215L are the single-pieces of the integral type that mainly forms by roll forming with sheet metal, thereby only need a kind of roll forming structure, be configured as left and right plate substantially the same but mirror image each other with follow-up.
Though two plates preferably at line of centers by the limit portion flange that supports being connected, will be appreciated that the height that also can make left and right plate neighboring edge different slightly (rather than forming flanges), thereby overlappedly connect to form overlap joint.But, be connected with the top limit portion flange of introducing and compare, this connection mode is considered to a bit weaker.
Process shown in top Figure 15 that introduces and 16 obviously also is applicable to the side/floor 162 that forms the integral type as shown in Fig. 5.
The roll forming of the plate of introducing above is very favourable, because this makes it possible to use high-strength steel sheet, especially yield strength at 50,000 pounds/sq in to about 100, sheet steel in the 000 pound/sq in scope carries out the shaping processing of this plate more easily.Thereby high-strength steel sheet can be shaped more easily and be out of shape by roll forming and make plate have desired three-D profile, especially can adopt stretching or the moulding darker than common punching press, and when design, can utilize thinner material, so the 3D shape of stronger (promptly darker) can also be provided when making weight saving.
When form in the plate at roll forming big aperture efficiency such as above introduced wheel cabin opening the time, will be appreciated that, this opening can be in the position of milling train upstream in thin plate continuously punching form.The punch operation that this use flies mould or quiet mould (static die) can form an opening that spreads apart, and oversize opening just is with the follow-up distortion of balancing sheet in the rolling process.Yet, in general preferably after roll forming, form opening.
It is consistent with orthodox method to a great extent to utilize the improved plate of the present invention to carry out the compartment overall package, so we think it unnecessary and will further illustrate.
Though explanation has described preferred embodiments more of the present invention in detail for example, will be appreciated that the modification of disclosed device or modification comprise that rearranging also of parts all belongs within the scope of the present invention.
