Specific embodiment
As shown in Figure 1, form is that the workpiece portion of final part 1 and the also dowel 3 of skeleton 2 can by elasticity
The separation processing of the sheet metal plate of deformable material is generated, and final part 1 is connected with each other by the dowel 3 with skeleton 2.
Dowel 3 is left in the separation process of sheet metal plate.Final part 1 and skeleton 2 are therefore not fully each other
Separation.
The construction of dowel 3 can be seen in detail in from Fig. 2, wherein the workpiece after processing in Fig. 1 or the piece after processing
The situation in the upper left angle portion of material metal plate is shown with being amplified.Other dowels 3 in sheet metal plate after processing are about it
Construction for dowel principle shown in Fig. 2 it is consistent.
Dowel 3 is obtained by the material processing of sheet metal plate.Dowel is formed by two workpiece openings, described two works
Part opening is created to be separated from each other in sheet metal plate.Dowel 3 is assigned to most using its straight end 6,7 one side
One in whole part 1, and on the other hand it is assigned to skeleton 2.In region 8 between end 6,7, dowel 3, which has, wriggles
The construction of Yan.Region 8 includes V-shape 9, with leg 10,11, transitional region 12 that the leg is connected with each other and
There are also additional legs 13, and the additional leg is connected to the leg adjacent thereto of V-shape 9 by additional transitional region 14
Portion 11.With same its adjacent leg 11 and additional transitional region 14 of V-shape 9 together, additional leg 13 forms connection
Another V-shape 15 of muscle 3.
The transitional region 12 of V-shape 9 and the additional transitional region 14 of another V-shape 15 are in leg 10,11；11,13
Between extend respectively along a circular arc, the circular arc extends on substantially 250 ° of central angle.Leg 10,11 and also leg
11,13 an interior angle is formd, substantially 30 ° in instances.The transitional region 12 of V-shape 9 and another V-shape 15 it is attached
The transitional region 14 added has than the adjacent smaller cross section in leg 10,11,13.
Based on described design, sheet material gold of the dowel 3 made of the material for the sheet metal plate processed in processing
Belong to plate be parallel to Fig. 2 drawing extend plate plane in have elasticity, and thus form flexible supporting part.Because of dowel
The bending stiffness that 3 end 6,7 has the cross section bigger than the sinuous region 8 between end 6,7 and therefore more arrives, so
The sinuous region 8 of dowel 3 mainly acts in a elastomeric manner.
According to Fig. 1, each final part 1 simultaneously thus by four flexible supporting parts is attached to by four dowels 3
The skeleton 2 of the sheet metal plate of processing.Due to the elasticity of dowel 3, final part 1 can against the effect of restoring force and
Change its position relative to skeleton 2.
In Fig. 2, one of final part 1 is shown to be in initial position relative to skeleton 2.If final part 1
From original position be parallel to the sheet metal plate of processing where plate plane earth it is deflected if, then in final part 1 and bone
3 flexible deformation of dowel being arranged between frame 2, changes simultaneously between the leg 10,11,13 of V-shape 9 and another V-shape 15
Interior angle.Since the dowel 3 of flexible deformation resets to initial conditions, so automatic from the final part 1 that original position deflects
Ground is back to original position.The clearance degree that final part 1 is attached to skeleton 2 is determined by the width of defiber 16, described
Defiber is visible in fig. 2 between final part 1 and skeleton 2 to a certain extent.
It in the example shown, is the separation for being cut by laser and being punched to sheet metal plate according to the situation of Fig. 1
The result of processing.The order of processing is shown specifically in Fig. 3 to 5, wherein Fig. 3 and 4 shows the laser beam for laser cutting
And processed sheet metal plate one of movement routine along which relative to each other in the plate plane where sheet metal plate
Part, so that the final part in Fig. 1 shown in upper left side not fully be separated with skeleton 2.
The separation processing of sheet metal plate is punched lathe (combined punch laser in traditional combined laser
Machine it executes on) and is digitally controlled.The laser beam of sheet metal plate and the separation processing for sheet metal plate
Relative motion generate in the following manner, i.e., so that sheet metal plate relative to combined laser punching lathe by laser
The laser cutting head of Shu Zhixiang sheet metal plate is mobile.For this purpose, sheet metal plate is fixed to combined laser punching lathe
Common coordinate guiding piece, and be attached in the workpiece support of lathe and moved by means of coordinate guiding piece.This
In situation, sheet metal plate is kept by means of the clamping claw of coordinate guiding piece, wherein clamping claw is in the region of skeleton 2
Grasp sheet metal plate.
In the coordinate system of the digital controller of combined laser punching lathe, the instantaneous position of sheet metal plate is passed through
It is defined by the instantaneous position of coordinate guiding piece.Because coordinate guiding piece grasps in the region of skeleton 2 by means of clamping claw
Sheet metal plate, so the instantaneous position of coordinate guiding piece represents the instantaneous position of skeleton 2.That arranges in skeleton 2 is final
Part 1 instantaneous position by combined laser punching lathe digital controller by means of coordinate guiding piece or skeleton 2
Instantaneous position determine that while in view of the plan of distribution that is stored in digital controller, and final part 1 is in sheet material
Distribution on metal plate is determined by the plan of distribution.

In described mode, (being arranged in the lower left comer portion of the final part 1 at upper left place in Fig. 1) the is formed
Then two workpiece openings of four dowels 3 are partly generated, and the 4th dowel 3 is fully generated.Such as Fig. 1 institute
Show, laser beam eventually arrives at the first dowel 3.First dowel 3 is fully created by the generation of corresponding defiber 16；
The workpiece openings 5 for together forming the first dowel 3 with workpiece openings 4 are partly created.
The workpiece area for the workpiece openings that filling setting is shaped to dowel 3 is still connected to skeleton 2.It is this to be connected to workpiece
It is realized in region close to 3 ground of dowel.In Fig. 5, the workpiece area at dowel 3 is by dotted line mark frame.Due to filling work
The workpiece area of part opening and the continuous attachment of skeleton 2, do not have workpiece notch necessary in the process of sheet metal plate
It is removed.In fact, can be follow by the workpiece area of the contour line mark frame of workpiece openings for working sheet metal plate institute
Movement of the sheet metal plate of execution relative to the laser cutting head of combined laser punching lathe.This means that not time-consuming
Uninstall action is necessary, the sheet metal plate movement processed relative to the laser cutting head of combined laser punching lathe
It will not be hindered by free workpiece notch.
Finally, the remaining connection between the workpiece area and skeleton 2 of filling workpiece openings is removed.For this purpose, sheet material
The punching station that metal plate is moved into combined laser punching lathe fills the workpiece area and bone of workpiece openings there
All remaining connections between frame 2 are punched by means of corresponding blanking tool.
Now, metal sheet plate is shown in Fig. 1 with machining state.Final part 1 and skeleton 2 is not fully each other
Separation；The dowel 3 for being configured to flexible supporting part produces interim elastic connection between final part 1 and skeleton 2.
It is additional processing after the separation processing of sheet metal plate.In this case, in the separation of sheet metal plate
Generated final part 1 undergoes edge processing in process.
Additional processing also executes on the punching station of combined laser punching lathe.Here, the punching used in the recent period
Tool is replaced with forming tool, is replaced with rolling folder tool (roller pinching tool) 37 in this example.Rolling folder work
Tool 37 is included in forming rolls 38 shown in Fig. 6, the upper work being introduced on the punching station of combined laser punching lathe
On part holder.Attached bearing not shown in the figure, lower tool of the bearing in combined laser punching lathe are configured for forming rolls 38
It is installed on holder.
The forming rolls 38 of rolling folder tool 37 is provided with biconial press strip 39, and there are two tapers to shape for the biconial press strip tool
Surface 40,41.Taper shapes surface 40,41 relative to the central plane of biconial press strip 39 being represented by the dotted line in Fig. 6
Mirror symmetry.
In order to execute additional processing, sheet metal plate is opposite by means of the coordinate guiding piece of combined laser punching lathe
Rolling folder tool 37 in the punching station for being introduced in combined laser punching lathe is located in the processing according to Fig. 1
In state.Controllably, the sheet metal plate of processing is arranged in this case, in final part to be processed for digitlization
The central plane weight of the biconial press strip 39 of the longitudinal median plane and forming rolls 38 of the defiber 16 extended between 1 and skeleton 2
It closes.Forming rolls 38 is then lowered in the sheet metal plate of processing, and taper forming surface 41 is applied under pressure
Being added to will be on the edge of work 42 to be formed of processed final part 1.Sheet metal plate after processing followed by
The coordinate guiding piece of combined laser punching lathe is moved, so that being punched consolidating for the punching station of lathe in combined laser
The forming rolls 38 being rotatably mounted on fixed workpiece holder is rolled along the edge of work 42 to be formed of final part 1
It is dynamic, and slope/chamfering 43 (Fig. 6,7) is generated on final part 1 in doing so.Final part 1 is in such case
In on downside by rolling folder tool 37 unshowned bearing support.
By means of roll folder tool 37 additional processing start before processing sheet metal plate positioning and also
There is the movement for the sheet metal plate processed during the edge shaping on final part 1 to be punched lathe by combined laser
Digital controller controlled based on the data stored in the controls.However, these data do not consider processing
Unforeseen foozle in sheet metal plate, for example, final part 1 to be processed is relative to the unexpected of skeleton 2
Location of mistake, be being deformed to the relevant material of heat in the separation laser processing procedure due to sheet metal plate.Therefore, may be used
With it is envisioned that the sheet metal plate being processed to be appendedly relative to rolling folder tool 37 it is initial position after, defiber 16
The longitudinal median plane as defined by the edge of work 42 to be processed relative to rolling folder tool 37 forming rolls 38 on bipyramid
The central plane of shape press strip 39 is laterally offset from.
If forming rolls 38 is applied to final part 1 to be processed with taper forming surface 41 in this case
If the edge of work 42, then final part 1 is due to its bipyramid relative to the mobility of skeleton 2 and relative to forming rolls 38
Shape press strip 39 balances out the longitudinal median plane and forming rolls 38 for being initially present in defiber 16 by automatically to just
Biconial press strip 39 central plane between deviation.In a corresponding way, final part 1 is in forming rolls 38 along workpiece
It can be automatically adjusted during the rolling movement at edge 42 relative to forming rolls 38.
Due to the elasticity of dowel 3, final part 1 is from initial position relative to skeleton 2 (with final part 1
Automatic alignment relative to forming rolls 38 is associated) deflection be not permanent.In fact, the elasticity of dowel 3 means
After the edge of work 42 is shaped and after final part 1 is released pressure from forming rolls 38, final
Part 1, which is automatically moved, returns to its initial position.
The fact that in following situations be it is especially important, i.e., after the forming of the edge of work 42, final part 1
It is provided with slope on other edges of work, such as is initially provided on an edge of work perpendicular to the edge of work 42 tiltedly
Slope.If the edge of work also from start setting up into relative to skeleton 2 from desired position deviate and if if dowel 3
If automatically being deformed during final part 1 is to edge processing relevant automatic alignment, position inaccuracy
Uncontrolled chain will generate, this significantly affects the precision of the edge processing of final part 1.
After the completion that the edge of all final parts 1 processes, final part 1 and skeleton 2 must each other completely
Ground separation.For this purpose, dowel 3 be initially provided with respectively in its end 6,7 it is transversal between final part 1 and skeleton 2
Weaken structure in face.The procedure of processing also executes on the punching station of combined laser punching lathe.Forming tool 44 is this
It is used in situation comprising the forming punching of the hollow cylindrical in the upper tool retainer of combined laser punching lathe
Mould 45 and the workpiece support in the lower tool retainer of combined laser punching lathe.In that side towards workpiece
On, the wall of the forming dies 45 of hollow cylindrical is equipped with the slope to extend internally.Therefore, the forming dies 45 of hollow cylindrical
The edge acted on workpiece to be formed is formed to have trapezoidal cross section.
It is represented by the dotted line the parallel outer lateral surface of axis of the forming dies 45 of hollow cylindrical in fig. 8 in dowel
Upright projection on 3.Therefore, the diameter needles of the forming dies 45 of hollow cylindrical are smart to the size of dowel 3 to be processed
Really adjust.
By means of the coordinate guiding piece of combined laser punching lathe, the sheet metal plate of processing is processed final with edge
Part 1 positioned relative to forming tool 44 so that on the one hand the forming dies 45 of forming tool 44 on the other hand to
The dowel 3 of processing is mutually arranged realization as shown in Figure 8.
Then dowel 3 is applied and reducing forming dies 45 with its free end.In this way, dowel 3
The cross section decrease portion 46,47 being represented by the dotted line in fig. 8 is equipped at end 6,7.Due to the forming acted on dowel 3
The trapezoidal cross-section at the edge of punch die 45, so the cross section decrease portion 46,47 at dowel 3 has inclined surface 48,49, institute
It states inclined surface with respect to the horizontal plane and horizontal base-plates surface 50,51 oblique angles is arranged.
Finally, dowel 3 separates at cross section decrease portion 46,47 with final part 1 and skeleton 2.Separation can be with hand
It realizes dynamicly.However, it could be imagined that be using separating tool.For example, on the one hand dowel 3 and on the other hand final part
Connection between 1 and skeleton 2 can be in the region at 50,51 place of base-plates surface in the cross section decrease portion 46,47 of dowel 3
It is destroyed by means of laser beam.In each case, it is necessary to consider that the trace at most slightly of dowel 3 is in isolated process
In stay on final part 1.
With state as shown in Figure 1 on the contrary, multiple final parts also especially can be by means of shared elastic connection muscle
Be attached to skeleton and/or final part can be also especially connected with each other by one or more elastic connection muscle.For example, this
Processing situation is shown in FIG. 9.Final part that is not being completely separated each other and/or not being kept completely separate with skeleton is this
It is reappeared in situation by shade.
