Description
Background technology
When producing so-called flanged type path, form member by means of the combination of tensile load and compressive load, used to comprise decompressor and die unit or have so-called template that leads directly to sleeve pipe or the two-piece tool of tightening up plate.For this reason, member is positioned between decompressor and the die unit, is stamped then, and forms protruding collar shape edge around the formed hole on member one side through the material area of deep-draw and mobile member.Flanged type path---it is also referred to as the hole, metallic plate edge or the collar---can be used for various objectives, and for example as being used for the threaded pathway that screw connects, internal thread and/or external screw thread are arranged on the flanged type path for this reason.
Summary of the invention
The objective of the invention is to improve the generation of flanged type path at technological and economic aspect.
This purpose realizes through independent claims.
More how favourable design of the present invention illustrates in the dependent claims.
The present invention at first relates to a kind of equipment that is used on member, producing the flanged type path; Said equipment has with the interaction of position accurate way to produce the die unit and the decompressor of flanged type path; Wherein die unit can be arranged on first side of member and decompressor can relatively be arranged on second side of member, and wherein produces the flanged type path through going out material area from member and being connected to the surplus material zone of going out material area through formation.This member can be straight, the tubulose particularly processed by metallic plate or the part of abnormity, and the generation of flanged type path is particularly carried out on the straight section of this member.
An importance of the present invention is the hollow drift that decompressor comprises band drift recess; Said drift recess matees with the die segments of die unit by this way; Promptly; When existence between die unit and the decompressor relatively moved, die segments got into the drift recess, wherein goes out material area and is pushed into the drift recess.
During producing the flanged type path, the hollow drift---also is applicable to the another part of the holding device that is used for member here---and/or at least a portion of die unit relative to each other moves sometimes at least.This can be for example only through the hollow drift move, only at least a portion through die unit moves or the two moves and realizes through hollow drift and die unit.The accurate layout also limits the axis of operation that particularly overlaps with the longitudinal axis of die unit or decompressor on the position of hollow drift and die unit.In addition, during producing path, axis of operation overlaps with the central symmetry axes of formed path, and the member that is under this state is remained between die unit and the decompressor regularly.
Therefore, get into and do not mean that die segments must under any circumstance all be moved, on the contrary, die segments keeps not moving and the hollow drift moves along the direction towards die unit or die segments.The hollow drift can for example particularly move around by means of driven plunger by means of drive unit.In an advantageous manner, relatively moving between die unit and the decompressor realized in a stroke.Like what require among the present invention to protect, the different sections of hollow drift and die unit can interact between single stroke and make member can use all the intactly generations step by step in this stroke.Up to now, this can only realize in two or more strokes, perhaps uses relatively more expensive device or the device that is not suitable for producing in batches to realize.
In addition, in an advantageous manner, material area to be gone out can separate with member with accurate way very, is not particularly forming sharp edges or is not forming under the situation of any burr and/or chip.Up to now, often have sharp punching press edge on the edge in the hole in being formed on member, this can cause personnel to injure or damage other object in follow-up operating period to member.Utilize the equipment proposed, can on the flanged type path that is produced, form sharp outline, even but stubbed edge with reproducible mode.
The difference of a favourable remodeling of the object of the invention is to be arranged in such a way removable and contacts to produce the holding device of flanged type path with second side of member; Promptly; When producing the flanged type path, member is maintained between die unit and the holding device.Utilization abuts the holding device that is supported in the member on the die unit, and member can be firmly fixed (for example clamping) between holding device and die unit.
With preferred mode, holding device this means that slightly prior to hollow drift contact member member is fixed with cocksure mode during the processing that is shaped.Yet member for example sheet metal advantageously just not long ago was clamped between holding device and the die unit before the processing beginning that is shaped or in the processing beginning that is shaped.
After the generation of flanged type path finishes; Holding device still keeps second side contacts with member in an advantageous manner; Make that for example through the hollow drift is moved away under the situation of backward stroke that member is connected to operative strokes, member remains on the die unit and is drawn out from member fully up to hollow mould.This means, in an advantageous manner, can in robot, use, particularly when needs do not have self-balancing processing etc. like the production equipment that requires protection among the present invention.
In addition, propose can in the single stage, make the mode of material area drawing design decompressor and die unit.This makes can simplify the complete operation that produces the flanged type path.Therefore, can in a mobile stroke, realize two kinds of different-diameters providing by the die unit that is proposed.
Disadvantageously up to now be under the situation of the equipment that is used to produce the metallic plate path that is fit to practice, to need two stage method.In the phase I, the relevant section of pre-punching member and expansion member, then the phase I is the second stage that finally forms the metallic plate path.
This causes long circulation timei.In addition, two stage operation is owing to relate to automatic control and more complicated.
Especially, like what require among the present invention to protect, during producing the flanged type path, can remove the rotation mobile member of element to be moved or decompressor from.Up to now, for example made a try to simplify or shorten and produced the flanged type path by means of live spindle.Yet; In this case; Disadvantageously especially be, urge on the surface of member and with the mode of pressurization and heating soften point-to-pointly said component surface and subsequently the live spindle of drag down material on path, produce very sharp breach (interruption) or marginal texture.
In addition; Like what require among the present invention to protect; Advantageously design decompressor and die unit by this way; That is,, be used to produce the generation of accomplishing the flanged type path under the situation that direction that operating period of said flanged type path begins to move need not reverse at the moving meter of decompressor and/or die unit in the operating period that forms the flanged type path.Therefore, can carry out the generation operation quickly and with technical favourable mode.Especially, moving of hollow drift and/or die segments can be from beginning not have any interruption or execution continuously, in an operating procedure, to accomplish.This means and to realize higher cycle frequency.
In an advantageous manner, the hollow drift is taken in so that can in holding device, move.Therefore, in all stages of production operation or during the hollow drift moves, can fix member by means of holding device.Being moved further of equipment or member can directly be carried out after member upgrades at holding device.The mobile of hollow drift and holding device can mate with the processing sequence of expectation with the mode of the best independently of one another.This particularly by means of computer for example the higher level control module control or the adjusting device that for example are used to regulate production equipment realize.
The hollow drift of decompressor is prior to or subsequent to holding device and realizes.This means can be with variable mode Design and Machining order.Therefore, when producing the flanged type path, the hollow drift can be before or after the holding device contact member contact member.
Equally advantageously, die segments comprises the mould axle of the convexity that realizes for the mode with accurate cooperation is bonded in the drift recess.Especially, realize that the profile of mould axle and/or external dimensions make the mould axle for example to get into the drift recess with the mode that is slidingly matched relatively with the gap of expectation.Gap between the inwall of the outer wall of mould axle and hollow drift can be confirmed with accurate way by means of the design of hollow drift or mould axle in advance.This gap can for example be selected to different materials differently.This means that for all about member thickness and construction material, material area to be gone out can be gone out or cut from member with clean and carrot-free mode, therefore got rid of sharp edges, material peels off or burr.In addition, member can be with reliable and reproducible mode by punching press in advance or punching.Especially, can realize via rectangular each other member section when in cutaway view, observing at edge outstanding on first side of member.
The insertion depth of mould axle must be at least enough big; Making member in a stroke, dashed wears; In addition simultaneously, material to be out of shape is shaped in a corresponding way and produces up to path, and this makes needs the mould axle that certain minimum insertion depth is arranged in the drift recess.
Further advantageously, die unit has the support section that is used for first side of supporting member when producing the flanged type path.This means that die unit can serve as the supporting member that is used to be supported member above that.It is particularly advantageous during with member section relative with the contacted section of holding device on support pattern contact and the member when support section.Like this, member can be to be firmly fixed or the mode of clamping is maintained at its operating position when producing the flanged type path.
Support section is arranged so that it is particularly via the surface of annular first side with smooth mode contact member.In a corresponding way, holding device can be arranged so that said holding device also via second side of the surperficial contact member of annular, and first side of member and the contact surface general size of the annular on second side equate.Contact surface on the member normally smooth or straight because particularly the component forming of plate shape be make the contact surface of pairing of holding device and support section be designed to straight or smooth in case advantageously with member on contact surface carry out the surface and contact.
In addition, advantageously between support section and mould axle, realize die cavity.The structure of this die cavity and size can be confirmed with the mode of regulation in advance, particularly can realize that with recessed mode a said end is directed towards decompressor with respect to support section or with respect to an end of mould axle.This die cavity provides a free space, and the construction material that during producing the flanged type path, is shaped can deflect in the said space, and material perhaps to be formed is by deep-draw or be pressed into wherein.
In addition, advantageously have die cavity between support section and the die segments by this way, that is, during producing the flanged type path, towards the engaged at end of the directed hollow drift of die unit in annular gap.Therefore, near the material that exists the material area of punching press can be shaped by means of the interaction between area supported, die cavity and the hollow drift at least, thereby forms the flanged type path of expectation.
Together with the space that is provided for material to be formed; Therefore said die cavity also make when existing between hollow drift and the die unit when relatively moving, and the end of hollow drift or the sleeve-like wall section that for example limits the hollow drift of the drift recess that leads to the outside can get into die cavity.Therefore, die cavity must mate the outstanding edge and the space that is used for the entering part of hollow drift that makes wherein existence be used for the collar to be formed.Therefore, by means of the structure of volume that is provided and/or die cavity,, then also can confirm the height or the shape at the outstanding edge of the collar if the quantity of material that begins to be shaped is identical.Have at die cavity under the situation of less volume; That is to say; For example, exist between the wall of mould axle and die cavity under the situation in narrower gap, said wall further is positioned at the outside with respect to said mould axle radial arrangement and with respect to operative axis; The material that is shaped is stamped deeply or is pressed further into die cavity, so the collar is higherly outstanding on first side of member.Have at die cavity under the situation of big volume, it shows with opposite mode.The volume that is arranged for the die cavity of shaping also receives the size or the shape affects of the front portion of hollow drift.
Said die cavity is particularly realized with the shape of endless groove and with respect to operative axis with one heart.The wall of die cavity through the mould axle limits and being connected to area supported and limiting at radial outside along the section that extends away from the direction of decompressor through die unit at radially inner side with respect to operative axis.The inner radial wall of die cavity and outer wall are particularly particularly parallel with the mode of endless belt.Die cavity can be according to application and difference along the degree of depth of the direction of operative axis, and for example it can be wide enough so that also the moulding material zone keeps not contacting with the section of mould on this direction.
Transition from support section to the die cavity that connects particularly can realize via the radius that can limit in advance, so that can under the situation of the material of not tearing the transition position between straight section and the edge, form the outstanding edge of flanged type path.
What further propose is, the mould axle is designed to be provided for the area supported of first side of member, and said area supported at least roughly is arranged in the plane of the area supported that comprises support section.This means that member further was supported in the central area of path to be formed at least before actual punch process.Area supported is shaped so that particularly it can abut first member side of member with straight mode.By the surface of first side of the member of area supported supporting and the material area of going out subsequently or with so-called punching press or cut relevant.
As requiring the die unit of protection can be transform as the punch die that has core among the present invention, the mould axle forms said core, and support section further is arranged on the outside, is die cavity between the two.Utilization can obtain two kinds of different dies diameters with the hollow drift of prescribed manner and punch die coupling in an operative strokes.First effective diameter or internal diameter form via edge or its area supported of mould axle.Second effective diameter or external diameter are fixed through the edge of support section, and said edge is positioned at radially inner side with respect to operative axis.Said two diameters are used by hollow drift and the die unit that part relative to each other mobile or wherein in a stroke is engaged with each other.
According to as requiring a favourable modification of protection among the present invention, die cavity has shoulder, and this shoulder serves as the stopper section of the construction material that is used for during producing the flanged type path directly being shaped at die cavity during producing the flanged type path.Like this, especially, can form path qualification end or edge towards first of the member side-prominent end face, said end face becomes axially with respect to operative axis.The material of distortion is limited the stopper section, and this has improved crudy.As a result, path is more accurate on geometry, because the drawing depth of shaping operation is defined or limits.
Die cavity also can be designed to not be with shoulder, particularly is not with and presses the anvil member.Yet, in principle, shoulder can be set through the structure of die cavity make existence not with the shoulder of pressing the anvil member.
In an advantageous manner, the shoulder of die cavity forms through the interchangeable member that can insert die unit.Like this, interchangeable member for example sleeve shaped insert or press the anvil member to insert or to stay the outside with optional mode.In addition, the pressure anvil member of damage or wearing and tearing can easily be changed.In addition, can under the situation of a die unit, realize different stopper sections through inserting different pressure anvil members in each case.Suitable pressure anvil spare also can be inserted into die cavity or stay the die cavity outside with optional mode.
What further propose is that die cavity is provided with and is used to that die cavity is ventilated and/or the connection device of ventilation.Like this, can prevent contamination build-up or can blow away or sop up the foreign matter in the die unit zone by means of compressed air by means of negative pressure.Sopping up or be blown into air for example can realize by means of at least one pipeline of a side that is branched off into the die cavity below.
In a favourable remodeling of this production equipment, decompressor can design towards the mode that the free end of decompressor is discharged to go out material area.Even this means in hope and discharge forward under the situation of punching press material, can use as requiring the equipment of protection among the present invention.
In an advantageous manner, but the profile stray circle cylindrical form of decompressor and/or punch die tool unit.Like the functional of the equipment that requires protection among the present invention so be not limited to the substantial cylindrical outline or the interior profile of decompressor and/or die unit.
In addition; A kind of method that is used for producing at member the flanged type path is proposed; Wherein die unit and decompressor interact to produce the flanged type path with accurate way on the position; And die unit is arranged on first side of member and decompressor relatively is arranged on second side of member, and produces the flanged type path through going out material area from member and being connected to the surplus material zone of going out material area through formation.Like what require among the present invention to protect, go out material area and discharge by means of decompressor.Going out material area or so-called punching press material can discharge by means of a side that is particularly suitable for this purpose of two-piece tool in an advantageous manner, particularly because decompressor is typically connected to drive unit and/or other feeding unit.Decompressor or punch elements usually are actuated to just removable, and this make to discharge punching press material or temporarily is stored in this zone of instrument it relatively simpler.The connection of decompressor realizes via at least one corresponding connecting elements, can be on said connecting elements or therein the discharge of punching press material is set integrally and does not have any problem.Under the simplest situation, for example, only output pipe can be set, when in circulation, producing a plurality of path successively, to spread out of the punching press material of accumulation successively.The carrier of the punching press material for example principle of basis " promotes next " is sent in storage tank or the reservoir and can temporarily be stored in here.Can or empty storage tank in crucial stage to circulation timei of production method frequently then.As replacement, replace storage tank, can adopt continuous mode that the output of punching press material is perhaps exported each punching press material separately by means of output pipe.Also but sucking-off punching press material is perhaps discharged it forward by means of drift.
With preferred mode,, go out in the drift recess in the hollow drift that material area is pushed into decompressor when existing between die unit and the decompressor when relatively moving.For instrumental purpose wherein on member and its to function and required responsive especially zone, space, discharge that can integrated in an advantageous manner like this punching press material.The hollow drift is particularly suitable for this purpose, because the punching press material is pushed into its drift recess and further guides the punching press material, and in order further to guide the punching press material and to be exported, requires minimum addition thereto here.For example, the drift recess is extensible for this reason, and perhaps output pipe is removable is connected near the drift recess and with it.
The invention still further relates to a kind of instrument that is used to produce the flanged type path, said instrument has the equipment of realizing as in one of above-mentioned modification, requiring protection.Preceding text can be realized to the advantage that the two-piece tool of the correspondence that is used to produce the flanged type path is described like this.Especially, this instrument can be adapted at using in the Robotics or can being incorporated in the robot.Especially, this instrument connects compatible to certified connection standard, for example for known riveted joint, harden and close or stamping tool.Like this, for example, the system that exists as drift retainer and stripper can be used for for example riveting technology.For example, existing riveting die can be used as basic die body.This means and to reduce various modification and increase flexibility like the equipment that requires among the present invention to protect.Drift or hollow drift can be based on modified catalogue or standardized product settings.Especially, can select the instrument relevant to measure according to DIN with this processing.
The drive unit of the movable part of decompressor or hollow drift can for example be realized through the known drive unit that is used for the general system that is correlated with gas-liquid, pneumatic or electronic mode.

The specific embodiment
The counterpart member of replacement exemplary embodiment shown in Figure 5 has been used the Reference numeral identical with other accompanying drawing.
Fig. 1 shows as requiring the perspective view of instrument 1 that is used to produce the flanged type path of protection among the present invention, and it is member to be processed 2 dish type or straight metallic sheet material material with the size Expressing of dwindling that said instrument has at this.
Instrument 1 comprises decompressor 3 and nip side die unit 4, and member 2 is positioned at the assigned position between said decompressor and the die unit.The decompressor 3 that is formed with the substantial cylindrical profile comprise nose circle cylindrical sections and external diameter bigger be connected cylindrical sector 3a; The nose circle cylindrical sections has the hollow drift 7 that in holding device 8 (referring to Fig. 2 to 5), is directed, and the punching press material storage element 5 that has punching press material output pipe is connected to said cylindrical sector 3a.Punching press material storage element 5 can be connected to the more multizone (not shown) of instrument 1.Die unit 4 can also be incorporated on the section of pairing by means of jointing 6.
Fig. 2 shows the schematic cross sectional views like the indoor design of the instrument 1 that requires protection among the present invention, and wherein hollow drift 7 is being columniform on the outside and in decompressor 3, is being directed so that can move with respect to die unit 4 according to four-headed arrow P1.The holding device 8 of decompressor 3 remains on fixing position and it is pressed against on the die unit 4 especially for will be inserted into member 2 between decompressor 3 and the die unit 4 via the end face of said holding device contact section 8a.In this case, holding device 8 is installed with spring-loaded mode by means of elastic devices 9 (not shown more details).Hollow drift 7 is held device 8 and surrounds with protected mode, has the duct 8b that is used for taking in center on Page hollow drift 7 in the holding device 8.Hollow drift 7 merges to along the direction of die unit 4 via transition part 7a has less outside diameter d
3And engagement member 2 or pass in the zone of member during the processing that is shaped.
In order to produce the flanged type path, member 2 is put via first side of member or via its downside and is leaned against on the support region 13, and said support region 13 is realized and is arranged on the front of die unit 4 with annular and smooth mode.For the position of fixed component 2, contact area 8a is pressed against on the second relative side of member 2 or member and support region 13.For this reason, holding device slightly moves prior to the direction of hollow drift 7 along member 2.This is shown in Fig. 3, and according to Fig. 3, member 2 is clamped in the fixed position between decompressor 3 or holding device 8 and the die unit 4.
Flanged type path 19 is accomplished along all mobile back of the direction of die unit 4 at hollow drift 7.According to Fig. 5, the flanged type path 19 that in member 2, produces shows the outstanding edge on the downside 2a of member 2.Edge that forms by this way or dome convexity can be shaped via revising further under suitable situation, to form the bolt of screw threaded arrangement on the outside.Like this, bolt can be replaced (otherwise bolt will be sealed on or be pressed into) in an advantageous manner, and this obviously is located at the inner scheme in outstanding edge than the screw thread that is proposed and more saves cost.
After the processing that is shaped, hollow drift 7 moves back to corresponding to directly in the starting position (Fig. 5) according to the position before the shaping of the member 2 of Fig. 3 away from die unit once more.The punching press material 18 that during the generation of flanged type path, is pushed into punching press aperture 10 is to be remained on wherein and therefore to be removed from die unit 4 with hollow drift 7 by the mode of clamping slightly.If had some punching press material (not shown) owing to the punching operation of front in the punching press aperture 10, then these punching press material are promoted through moving further of the current punching press material 18 that is rushed out together.
Microscler outstanding mould axle 14 with cylindrical outer shape along decompressor 3 and die unit 4 vertically with respect to operation or combine axis S medially or in the middle of die unit 4 to be provided with, said mould axle is at its smooth area supported 14a in the face of having first member side that is used for member 2 on the end face of decompressor 3.Also at this member 2 of following side bearing of member 2, area supported 14a at least all is arranged in the plane that forms through support region 13 to area supported 14a.
The mode that mould axle 14 is fixed with the position is arranged in the die unit 4, and its outside diameter d
1Minimum degree ground or only slightly less than the inner diameter d in the front portion of drift endoporus 10
2Relatively moving as requiring the favourable shaping that can in single stage or stroke, realize and realize the flanged type path of protection in the present invention between hollow drift 7 and the die unit 4 do not exist sharp edges or burr in the zone of the hole 2b that particularly on member 2, goes out at this moment.
With particularly advantageous mode, the die unit 4 that is proposed has simple design, smaller wire (filigree), and therefore very firm.
In an advantageous manner, the outside diameter d of hollow drift 7
3Inner diameter d at its forefoot area internal ratio die cavity 15
4One times of the wall thickness D of the projecting edge of the shaping of little said flanged type path.In this case, die cavity 15 exists as the exterior domain and the uniform circular gap between the mould axle 14 of die unit 4 in an advantageous manner.
Die cavity 15 by means of at least one, particularly three ventilate and/or vent line 16 realizes that said pipeline 16 is evenly distributed on the circumference of die unit 4, be used to avoid or removal instrument 1 on pollutant.
Fig. 5 shows a modification like the die unit 4 that requires protection among the present invention, as with unique difference according to the device of Fig. 3 and 4, this die unit 4 has the pressure anvil 20 that inserts die cavity 15 and shoulder 21 is provided in die cavity 15.Be provided for the stop surface 20a of annular of the end of path 19 by shoulder 21.The edge that this means the qualification of path 19 is limited on the downside of member 2.
In principle, also can use to have and replace the so-called switchable die unit to opening structure rigidity or single-piece die unit 4.The advantage of this die unit is that two pre-punchings that as requiring protection among the present invention, can move and not have handover operation simultaneously separate with the processing that is shaped each other fully, and final power to be applied like this is less.It is so firm that this can make structure more expensively to a certain extent perhaps.In addition, processing separates will be merely " standard " single stage, because the relatively shorter return of the element that the work in-process requirement is moved moves, and therefore needs controlled drive unit, particularly electrically driven.
