Description
Technical field
The present invention relates to a kind of method of door-plate shaping for being used to make the door in particular for home appliances and one kind are logical
The door crossed methods described and obtained.
Background technology
It is known that when manufacturing refrigeration unit door, making sheet material blank be bent on two opposed edges, to form door
The foreboard of plate and two edges demarcated respectively by a front seamed edge and foreboard.The profile material obtained can be reinforced, its
Mode is, a flanging is formed separately by the extruding of forming tool at the upper and lower edge of the profile material, the flanging with preceding
Front seamed edge on plate both sides intersects.If foreboard is plane, front seamed edge is deployed at a right angle respectively.If foreboard is protuberance
, i.e., when with the cylinder curvature with vertical cylinder axis, then the angle typically larger than right angle deployed by front seamed edge, because
Oriented for side along along the thickness direction of door.If door must be with the protuberance of same curvature radius but with different width systems
Make, then the angle deployed by front seamed edge increases also with the increase of the width of door.The different angle must be also in shaping
Retrieved in instrument, the forming tool in order that flanging forming and be forced on foreboard and edge.Therefore, it is respectively necessary for difference
Instrument, so as to make different in width, protuberance and do not swell door-plate shaping, this make it that the manufacture of different gate-type samples is bothersome simultaneously
And it is expensive.
The content of the invention
The task of the present invention is, provides a kind of method for being used to shape door-plate, can be with cost advantages by this method
Also it may have any different in terms of ground manufacture door not in specie, the domes of the Men Qi foreboards and in terms of its width.
The task is solved by a kind of method for being used to shape door-plate, and methods described has following step：
A) sheet material blank is provided,
B) longitudinal direction extension, the first edge of division the middle edge along the first edge of door-plate is made in sheet material blank
Side shapes,
C) shape in door-plate the first front seamed edge, first front seamed edge makes foreboard and the first edge demarcate,
D) the first flanging forming is made on the top edge or lower edge of blank, the first front seamed edge of first flanging and door-plate
It is intersecting,
Front seamed edge is shaped in the style of the foreboard with different archings with identical cross section, in contrast to this, middle
Seamed edge is shaped in the style with different shaping foreboards with different cross sections.It therefore, it can independently use with style
Identical forming tool makes the first flanging forming, and which greatly reduces the cost for manufacturing different gate-type samples.
The method according to the invention as a result, edge is located at region between the first front seamed edge and the first middle seamed edge
Orientation can be changed according to the domes of foreboard.Because the width in this region can keep non-compared with the width of foreboard
Often small, so for the user for the home appliances being made, can hardly find out, the region is thickness exactly along door
Spend direction orientation or whether its orientation is somewhat different than the orientation.
Step b) and order c) are inessential for the method according to the invention.In practice, step b) is mostly in step
C) carried out before because the shaping of various different seamed edges in the way of being carried out from the edge of blank to centre ratio with along phase negative side
Mode to progress is simpler.
Not only the first front seamed edge but also the first middle seamed edge can be bent towards recessed inside door-plate so that edge is the
One that side of middle seamed edge forms a section, and the section is opposite with foreboard and can be used as gripping surface, so as at this
Door is caught in gripping surface and the door is pulled open.
In order to ensure the domes with foreboard are independently determined the region for being located at middle that side of seamed edge at edge
To, by the first middle edge skirt into angle in the style of the foreboard with strong arching should than with faint arching or
It is big in the style of the foreboard of not arching.
Flanging should be terminated between the first front seamed edge and the first middle seamed edge so that need not be examined when making flanging forming
The middle seamed edge of worry variable angle according to gate-type sample.
In practice, edge shapes on the both sides of blank, i.e. methods described preferably also comprises the steps：
B ') make at least one second edge along door-plate it is longitudinal direction extension, divide the middle seamed edge at the second edge
Shaping,
C ') the second front seamed edge is shaped, second front seamed edge makes the second edge of foreboard and door-plate demarcate,
D ') make the second flanging forming on the top edge or lower edge of blank, second flanging and door-plate second before rib
Intersect on side.
If only the door-plate shaping with fixed predetermined width and domes is made, single shaping work can be used
Tool, to make flanging forming, the flanging by foreboard whole width and extend continuously to side along upper by front seamed edge.
And in the range of the method according to the invention preferably, successive implementation steps d) and d '), so as to thus, it is possible to shape
Door-plate width independently use identical instrument, one be used for left folding while and one be used for right folding while.
Alternatively, can also simultaneously by means of two instruments that can adjust spacing to left folding while and implementation steps d) during right folding
And d ').
It particularly it may be necessary in wide gate-type sample, make the gap-closing between the first and second flangings, its side
Formula is, and then step d) and d '), make in the top edge of foreboard or the centre of lower edge by the first and second flanging coplanar connections
Flanging forming.
In order to be provided to door for the thickness needed for enough buffer actions, it might therefore be necessary to, make on edge
At least one correspondence seamed edge shaping, the correspondence seamed edge is oppositely bent relative to middle seamed edge.
Middle seamed edge should shape between front seamed edge and correspondence seamed edge.
Correspondence seamed edge can be uniformly horizontal with identical in the style of the foreboard with different archings as front seamed edge
Section shapes.
Preferably, a part for the grip groove that the formation of correspondence seamed edge extends on edge.
In addition, subject of the present invention is a kind of for home appliances, the door particularly for refrigerating appliance, the door has logical
Cross the door-plate of above method shaping.

Fig. 1 illustrates the blank 1 being made up of the steel plate of preferred japanning to overlook, and the blank can be according to according to the present invention's
Method is configured to door-plate.Blank 1 substantially have two linear edges of band rectangular shape, below according to after door-plate in family expenses device
Installation site in tool door is referred to as left hand edge 2 or right hand edge 3.The top edge and lower edge 4 or 5 of blank 1 divide in neighboring area 6
Not with the linear extension at a right angle of edge 2,3；In the central area at edge 4,5, elongated band 7 is respectively more than illusion, company
The straight line for connecing the neighboring area 6 at the edge 4 or 5 of correlation is protruded.The length at edge 2,3 and the length of band 7 can be with gate-types
Sample difference and change.
Various chain-dotted lines in Fig. 1 show the trend of bended edge, the bended edge in the manufacturing process of door-plate
Shaped in blank 1.Two in these lines with the line shown in 8 represent blank 1 after formed door-plate foreboard 9 that part
And door-plate in side is connected to border between the edge 10 on the foreboard 9.
Fig. 2 is exemplarily illustrated the possibility order of forming step, by the forming step by sheet material blank 1 obtain it is three-dimensional into
The door-plate of shape.In Fig. 2 a) to the forming step shown in f) it is roll forming stages, the roll forming stages are respectively in sheet material base
Symmetrically carried out in the left side of material 1 and right side, therefore, in Fig. 2 a) to the part for f) only showing sheet material blank 1 respectively.
Roll forming stages are carried out from the edge 2,3 of sheet material blank 1 to centre respectively.Therefore, Fig. 2 a) show to walk in the first rollforming
The cross section of blank 1 after rapid, by first roll forming stages, is close to the neighbouring shaping bending part 11 at edge 2, should
The recess for installing rear wall is formed on the back side for the door-plate being made after bending part.
Fig. 2 b) show cross section after another roll forming stages, to be formed directly by another roll forming stages
The trailing edge 12 at angle, the trailing edge can form the contact pin 13 extended on the back side in the door being made and side on the door-plate being made
Along the border between 10.
In Fig. 2 c) in add another obtuse-angulate seamed edge 14, the seamed edge as the trailing edge 12 towards blank 1, afterwards
It is recessed to form the surface 15 of the inner face of door-plate.
In Fig. 2 d) stage in, add the seamed edge 16 and seamed edge 17 at a generally normal angle that are protruded towards surface 15 into obtuse angle.
Make two other towards seamed edge (Fig. 2 e) in the middle of the recessed seamed edge in surface 15, one and (a figure of front seamed edge 19
After 2f) shaping, the edge 10 of door-plate is made, blank 1 keeps the indeformable region to form foreboard 9 between edge 10.Side
Grip groove 25 is formed between seamed edge 14,18 along 10, the section 26 parallel relative to foreboard 9 extends between seamed edge 17,18, made
The finger of user is securely positioned in when pulling the door open on the section.
Front seamed edge 19 shapes along line 8 so that top edge and the band 7 of the protrusion on lower edge 4,5 exceed foreboard 9 in side
Up to arrival edge 10 is in seamed edge 18, the planar section 20 of 19 gauges.
At this stage, foreboard 9 or plane.Whether the foreboard keeps plane or the door of protuberance whether is made
Plate, this is drawn by the shape of supporter 21, and the supporter is placed with onto surface 15 in the next step, to resist forming tool
Pressure support foreboard 9 and section 20, the forming tool then presses to foreboard 9 and section on the angle of door-plate from outside respectively
20, curve inwardly and thus make so as to the part for making band 7 flanging 22 that is pointed at a right angle relative to foreboard 9 and section 20 into
Shape, the flanging extends beyond front seamed edge 19 and thus reinforces the front seamed edge.Flanging 22 can be on all four angles of door-plate
Shaping in succession；Two flangings, its side can also be shaped simultaneously in side or up/down edge 2,3 or 4,5 adjacent angular
Formula is that two forming tools for being used to shape respectively flanging 22 are pacified with adapting to the width of foreboard 9 or the spacing of height respectively
Fill on the carrier and be extruded jointly.
Because for making width of the forming tool that flanging 22 shapes equally with foreboard 9 unrelated, especially having in door-plate
Following situations can be produced by having during wide style：Make on top on two angles of edge or lower edge 4,5 flanging 22 shape after, band 7
A part 23 it is not deformed and be in foreboard 9 in plane (see Fig. 2 h) in the centre of foreboard 21).
In another extrusion molding step, undeformed part 23 will be so far kept to be bent at a right angle with foreboard 9 so that
Shown in two flangings 22 (such as Fig. 2 h)) merge into continuous contact pin 24 from a section 20 towards opposed section.Thus, door-plate is obtained
Required rigidity is obtained, when the door-plate is arranged in refrigeration unit door and is foamed on the door, not produce the value of foreboard 21
Foaming process is carried out in the case of the deformation that must be noted.
Fig. 3 shows the transversal of the door-plate 28 of the door-plate 27 of the foreboard 9 with plane and the foreboard 9 with arching stackedly
Face.(cannot see that in figure 3) flanging 22 is on the left hand edge or right hand edge of the two door-plates 27,28 respectively by identical
Instrument shapes；Because the front seamed edge 19 on the left side of foreboard 9 and the right deploys same big angle respectively in two door-plates 27,28
Spend to amplify in α, such as Fig. 4 and show, these instruments can abut foreboard 9 and area in an identical manner on two door-plates 27,28
In section 20；The direction that only described instrument is extruded is slightly different for two door-plates 27,28.
Because the angle [alpha] in front seamed edge 19 is equal, the orientation at edge 20 is slightly different in two door-plates 27,28.
Different angle betas on middle seamed edge 18 that the different orientation passes through two door-plates 27,28, β ' are compensated so that two doors
The grasping section 26 extended in middle that side of seamed edge 18 of plate is parallel.As can be seen in figure 3, the horizontal stroke of two door-plates 27,28
In grasping section 26, that side is identical in section.In order to form slightly different angle beta, the β ' of two door-plates 27,28, it can use
Same rollforming instrument.
The upper left corner of door-plate that Fig. 5 shows to be made, the herein door-plate 28 of the foreboard 9 with arching.After showing to fragment
Wall 29 is arranged for being fixed in the contact pin 13 of that the corresponding side of bending part 11.The cover section 30 shown to same fragment is set
