Description

"Apparatus, method and tool for making a collar pass in a component"

State of the art

In the production of so-called Kragendurchzügen a component is formed by Zugdruckbelastung, with a

Two-piece tool is used, the one

Stamping device and a die unit or a

So-called form or recording plate with pull-through comprises. The component is for this purpose between the

Stamping device and the die unit positioned, then perforated and by deep drawing and displacement of

Material areas of the component to the resulting hole an elevated collar-like edge formed on a component side. The collar passage, which is also referred to as a sheet metal passage or collar, can serve different purposes, for example as a threaded passage for screwing, for which purpose an internal and / or external thread is introduced at the collar passage.

Purpose and advantages of the invention

Object of the present invention is the production of collar passages with regard to technical and

improve economic aspects. This object is solved by the independent claims.

In the dependent claims advantageous developments of the invention are shown.

The invention is initially based on a device for producing a collar pass on a component, with a die unit and a punch device, the exact position for the production of the collar passage

cooperate, wherein on a first component side the

Matrizeneinheit and opposite on a second

Component side, the punch device can be arranged, and wherein the production of the collar passage by punching a material region from the component and by reshaping of remaining material areas, which adjoin the punched-out material area, takes place. The component may be a flat, tubular or profile part, in particular made of sheet metal, wherein the production of the collar passage is made in particular on a flat portion of the component.

An essential aspect of the invention is that the stamping device has a hollow die with a

Stamp recess comprises, which is adapted to a die portion of the die unit such that the

Matrizenabschnitt at a relative movement of

Matrizeneinheit and the stamping device in the

Stamp depression dips, with the punched out

Material area pushes into the stamp recess.

In the production of the collar passage move

at least the hollow punch, possibly at times still another part of a holding arrangement for the component, and / or at least parts of the die unit relative to each other. This can be z. B. by the sole movement of the hollow punch, by the sole movement of at least parts of the die unit or by movement of both the hollow punch and the

Matrizeneinheit be realized. Due to the exact position Arrangement of the hollow punch and the die unit also defines a working axis, which in particular with a

Longitudinal axis of the die unit or the stamp device coincides. The working axis also falls in the

Producing the passage with a central axis of symmetry of the passage formed in the fixed held between the die unit and the punch device state of the component together.

The immersion therefore does not mean that the die section has to move in any case, but the die section remains stationary and the hollow die moves towards the die assembly or die section. The hollow die is in particular reciprocated via a drive, for example via a drive piston. The

Relative movement of the die unit and the punch device is advantageously carried out in one stroke. According to the invention, during the single stroke different sections of the hollow punch and the die unit cooperate so that the component in this one stroke completely with all

Sub-steps can be produced. So far, this could be done only in two or more strokes or with a comparatively

elaborate or not suitable for serial arrangement can be realized.

Furthermore, advantageously the auszustanzende

Material area are very precisely separated from the component, in particular without a sharp edge formation or without ridge and / or chip formation. So far occurs

sharp-edged punching edge on the formed hole edge in the component regularly on what injury to people or

Damage to other objects during subsequent handling can lead to the component. With the proposed device, a defined, reproducible,

form a uniform but not sharp-edged edge on the manufactured collar pass.

An advantageous modification of the subject invention is characterized in that a hold-down, which at the preparation of the collar passage with the second component side can be brought into abutment, is present such that the component is held in the manufacture of the collar passage between the die unit and the hold-down. With the hold-down, the against the at the

Matrizeneinheit supported component comes into abutment, the component between the hold-down and the die unit can be kept securely fixed, for example, clamped.

Preferably, the hold-down comes easily leading to

Hollow dies in contact with the component, which is an absolute

reliable retention of the component causes during forming. The component, for example, a sheet material, but is

advantageous only immediately or shortly before the start of

Forming process between the downholder and the

Clamping die unit.

After the end of the production of the collar passage, the hold-down advantageously remains on the second for so long

Component side in Appendix, that during a return stroke, which adjoins the working stroke, for example, by moving away the hollow punch from the component, the component remains on the die unit until the hollow punch is completely pulled out of the component. This is the invention

Manufacturing device advantageous for robot use, especially since no self-compensation or the like is necessary.

It is further proposed that the stamping device and the die unit are designed such that the stamping and forming of material regions is possible in one stage. This makes it possible to simplify the entire process of producing the collar pass. This will be in one

Movement stroke two provided with the proposed matrix unit different diameters effective.

So far it is disadvantageous that in arrangements for the

Manufacture of practicable sheet metal passages

two-step process is necessary. In a first stage is a pre-punching and a widening of the relevant Section of the component made, which is followed by a second stage, in which the final shaping of the sheet metal passage takes place.

This leads to longer cycle times. In addition, the

two-stage process control technology comparatively

complicated.

In particular, according to the invention in the manufacture of the

Kragendurchzuges be dispensed with a rotating movement component of a moving element or the stamp device. So far, for example, attempts by a

rotating mandrel to simplify the manufacture of the collar passage or shorten. But it is particularly disadvantageous that the rotating mandrel, which on a

Press component surface and softens these points under pressure and heat and then the material is pulled down, a very sharp-edged interruption or

Edge education at the passage arises.

It is also advantageous according to the invention that the

Stamping device and the die unit are configured such that a shaping of the component is completed during the manufacturing process of the collar passage, without reversing an initial during the manufacturing process of the collar passage

Movement direction of a moving element of

Stamping device and / or the die unit. Thus, the manufacturing process can be done faster and technically advantageous. In particular, a movement of the hollow punch and / or the Matrizenabschnitts uninterrupted or

continuously from start to finish in one work step. This allows higher clock frequencies to be achieved.

Advantageously, the hollow punch is within the

Hold-down movably received. Thus, in all phases of the manufacturing process or during the movement of the

Hollow stamp the component with the help of the blank holder

be held. The further movement of the device or the component can immediately after the lifting of the Hold down the component. The movement of the hollow punch and hold-down can be optimally adapted to the desired process sequence independently of one another. This is done in particular via a computer unit, for. B. a parent control unit, z. B. a tax or

Control device for regulating the production device.

The hollow punch of the stamp device is formed leading or trailing to the hold-down. Thus, the process flow can be made variable. The hollow punch can thus come into contact with the component during manufacture of the collar passage before or after the downholder contacts the component.

It is also advantageous that the die section comprises a raised die mandrel, which is designed for a precise fit into the punch recess. In particular, the outer shape and / or outer dimension of the die mandrel is formed so that the die mandrel into the die recess with a desired, for example

can dive relatively close game. The game

between an outer wall of the die mandrel and a

Inner wall of the hollow punch can be specified exactly on the formation of the hollow punch or the die mandrel. The game can z. B. can be chosen differently for different materials. This allows the punched out for all relevant component thicknesses and materials

Cut out or shear material area clean and burr-free out of the component, whereby sharp-edged edges, material breaks or burrs are excluded. The pre-punching or the

Punching the component can also be reliable and

be reproducible done. In particular, the protruding on the first component side edge with viewed in section at right angles to each other component sections

formable.

The immersion depth of the die mandrel must be at least so large that the component is punched through in a stroke and also the material to be deformed until the completion of the Durchzuges is reshaped accordingly, what a

Minimum immersion depth of the die mandrel in the

Stamp recess necessary.

It is further advantageous that the die unit has a support portion for supporting the first component side in the manufacture of the collar passage. Thus, the matrix unit can serve as a support for the component supporting it. In particular, it is advantageous if the support section abuttingly comes into contact with sections of the component which are opposite to the sections on the component which come into contact with the hold-down device. Thus, the component can be securely fixed or clamped held in its processing position in the production of the collar passage.

The support section is designed such that it comes into contact, in particular flat, with an annular surface on the first component side. Accordingly, the hold-down can be designed so that this also with a

annular surface on the second component side comes into abutment, wherein the annular contact surfaces on the first and the second component side are at least approximately equal. The contact surfaces on the component are usually flat or flat, since in particular plate-like components are reshaped, so that for an advantageous surface contact with the contact surfaces on the component and the mating contact surface of the blank holder and the support portion are flat or flat.

It is also advantageous that a Matrizenkavität is formed between the support portion and the die mandrel. The matrix cavity can be defined in shape and dimension

be given, in particular deepened relative to

Support section or to one end of the die mandrel

be formed, wherein the end is directed to the stamping device. The Matrizenkavität provides a free space in which material of the component, which in the

Production of the collar passage is reshaped, evade can or in which the material to be formed is deep drawn or pressed during the manufacture of the collar passage.

It is also advantageous that between the

Pad portion and the die portion, the Matrizenkavität is present such that in the manufacture of the

Kragendurchzuges a directed to Matrizeneinheit end of the hollow punch engages in the annular gap. That's how it works

adjacent to the punched material area existing

Material are formed by the interaction of at least bearing surface, Matrizenkavität and hollow dies so that the desired collar passage is formed.

In addition to providing a space for reshaping

Material allows the Matrizenkavität so that during the relative movement of the hollow die and die unit, the end of the hollow punch or z. B. a punch recess outside limiting sleeve-like wall portion of the

Hollow stamp in the Matrizenkavität can dive. The

Matrizenkavität must therefore be tuned so that there is room to form the protruding edge of the collar and the dipping part of the hollow punch. The height or shape of the protruding edge of the collar can therefore also be determined via the volume and / or the shape of the matrix cavity provided

to be determined, if one of an equal amount of

material to be formed. At a lower volume of Matrizenkavität, ie z. B. at a narrower gap between die mandrel and a radially to the working axis further outward wall of Matrizenkavität, the formed material is pushed deeper or further into the Matrizenkavität, the collar is characterized higher on the first component side over. Conversely, it behaves at one

larger volume of Matrizenkavität. The transformation

the available volume of the Matrizenkavität is also influenced by the size or shape of the front part of the hollow punch.

The Matrizenkavität is in particular ringnutförmig and

formed concentric to the working axis. The matrix cavity is limited to the working axis radially inwardly bounded by a wall of the die mandrel and bounded radially outwardly by a portion of the die unit, which adjoins the support surface and extending in the direction away from the stamping device. The radially inner and outer walls of the Matrizenkavität are in particular parallel

to each other, in particular ring-shaped strip. The depth of the Matrizenkavität in the direction of the working axis may vary depending on the application, for example, so large that the deformed material area in this direction

remains contact-free to die sections.

The transition from the rest section to the subsequent one

Matrizenkavität can be done in particular with a predeterminable radius in order to form the protruding edge of the collar passage without tearing material at the transition from the flat portion in the edge can.

It is further proposed that the die mandrel is configured to provide a bearing surface for the first component side of the

to provide, which is at least approximately in a plane with a support surface of the support portion. Thus, a further support of the component in a central

Area of the draft to be formed at least before the

actual punching achieved. The bearing surface is shaped in particular so that they are at the first

Create component side of the component surface. The surface of the first component side supported by the support surface belongs to the subsequently punched-out material region or the so-called stamped or sheet metal slug.

The matrix unit according to the invention can be described as a punching die with a core, wherein the die mandrel forms the core, with the intermediate Matrizenkavität further outward of the support portion is present. With the hollow punch defined on the punching die, two different die diameters can be effective in one working stroke. A first effective or inner diameter becomes with the edge of the die mandrel or its support surface educated. A second effective or outer diameter is defined by the radially inner edge of the support portion to the working axis. Both diameters come into play, in that the hollow die and the die unit move in a stroke relative to each other or parts of it dive into each other.

According to an advantageous variant of the invention, the Matrizenkavität on a paragraph, which in the

Production of the collar passage serves as a stop for a material of the component that in the manufacture of the

Kragendurchzuges is transformed into the Matrizenkavität inside. Thus, in particular a defined end of the passage or an axial axis to the working face of the first

Component side protruding edge are formed. The

Deformed material is limited by the stop, which increases the process quality. The draft is characterized geometrically determined because the depth of the forming process is defined or limited.

The Matrizenkavität can continue to be designed without paragraph especially without anvil component. In principle, however, the paragraph can be set up by the shape of the Matrizenkavität, so that a paragraph without anvil component is present.

Advantageously, the shoulder of the die cavity is formed by an insertable into the die assembly exchange component. For example, the replacement component, such as a sleeve-shaped insert or anvil member, may be selectively inserted or omitted. In addition, a can

damaged or worn anvil component easily

be replaced. Furthermore, at a

Matrizeneinheit different stops can be realized by each different Anvil components are used. A suitable anvil part can also be used in the Matrizenkavität optional or omitted.

It is further proposed that the Matrizenkavität with

Connecting means for aeration and / or venting of Matrizenkavität is provided. Thus, a dirt formation can be prevented or carried out a blow-off by compressed air or suction via negative pressure of interfering substances in the area of the die unit. The suction or blowing z. B. of air can be at least one below the

Matrizenkavität be realized laterally outgoing line.

In an advantageous modification of

Manufacturing device, the stamping device is designed such that the punched-out material area is ejected towards the free end of the stamping device out. Thus, the arrangement according to the invention can also be used in cases where the ejection of the punching nozzle forward is desired.

The contours of the stamp device and / or the

Matrizeneinheit can advantageously from a

deviate from cylindrical shape. The functionality of

inventive device is therefore not on a substantially cylindrical outer or inner contour of the

Stamp device and / or the Matrizeneinheit limited.

Next is a method for producing a

Kragendurchzuges proposed in a component, wherein a die unit and a stamping device for the

Production of the collar passage cooperate positionally accurate and on a first side of the component die unit and opposite to a second side of the component

Stamping device is arranged, and the collar passage by punching a material portion of the component and by forming of remaining material portions which adjoin the punched material region, is produced. According to the invention, the punched-out material region is removed via the stamp device. The punched out

Material area or the so-called stamped joint can

advantageously over that side of the two-part

Tool are dissipated, which is particularly suitable, since in particular usually the stamp device with a drive and / or other supply units connected is. As a rule, the stamp device or a stamp element is driven in a mobile manner, which is what it is

makes comparatively easy to dissipate the punching in this area of the tool or

temporarily. Because the connection of the stamping device is already realized with at least one corresponding connecting component, on or in the integrated, the discharge of the punching can be easily set up. In the simplest case, z. B. only one discharge line can be provided wegnachransportieren the nacheinender resulting punching slugs when a number of passes are produced in clockwise succession in succession. The transport of the stamped slugs can be transported, for example, according to the principle of "one pushes the next" in a memory or a reservoir and cached there. In a less

time-critical phase of the manufacturing process or from time to time, the memory can then be emptied.

Alternatively, instead of the memory via a discharge line continuously or each punching slug can be discharged individually. The punched slug can also be sucked off or ejected to the front with the help of the punch.

In the case of a relative movement of the die unit and the stamp device, the stamped-out material region is preferably inserted into a stamp recess in a hollow die of the

Pushed punch device. Thus, with regard to the area in which the tool acts on the component and which is particularly sensitive with regard to function and space requirement, the removal of the punched housing can be advantageously integrated. The hollow ram offers itself for this purpose, since in its stamp recess the punched slug is inserted, so that a continuation and discharge of the stamped from there makes the least additional measures necessary. The

Stamp depression can for example be extended or the discharge line can to the stamp recess

introduced and connected to it.

The invention also relates to a tool for producing a collar passage, with a device which according to a the above variants is formed. Thus, the advantages discussed above for a corresponding two-part tool for producing the collar passage can be achieved. In particular, the tool may be suitable for robots or may be accommodated on a robot. The tool is particularly connection compatible with regard to proven connection standards z. B. for known clinching, enforcing or. Punching tools. For example, as

Stamp holder and scraper existing systems for z. B. the clinching technology can be used. As Matrizengrundkörper can be used for example on existing Clinchmatrizen. This can reduce the variety of variants and increase the flexibility of the device according to the invention. The punch or the hollow punch can be provided on the basis of modified catalog or standard goods. In particular, the process-relevant tool dimensions can be selected according to DIN.

The drive of the movable part of the stamp device or of the hollow punch can be realized by known drive arrangements for related systems, for example

hydropneumatic, pneumatic or electric.

Representation of Figure 3 and 4, but after the production of a Kragendurchzuges.

Corresponding components of the alternative embodiment shown in Figure 5 were the same

Reference numerals used from the other figures.

Figure 1 shows in perspective an inventive tool 1 for producing a collar passage with a to

machining component 2, which is indicated here in reduced size here as a disk-shaped or flat sheet metal material.

The tool 1 comprises a punch device 3 and a bow-side die unit 4, between which the component 2 is positioned in a defined position. The stamping device 3 formed with an approximately cylindrical external shape comprises a front cylindrical section with a hollow punch 7 guided in a holding-down device 8 (see FIGS. 2 to 5) and a subsequent cylindrical section 3a with a larger outside diameter, against which a

Stamped waste storage 5 with a stamped waste discharge

followed. The stamped waste memory 5 can not with

be connected shown further areas of the tool 1. Likewise, the die unit 4 via a

Connecting portion 6 are received at a counter portion.

Figure 2 shows schematically and in section the internal structure of the tool 1 according to the invention with the outside cylindrical Hollow punch 7, which is guided in the punch device 3 relative to the die unit 4 according to the double arrow Pl movable. A hold-down 8 of the stamping device 3 is used

in particular, with its frontal

Contact section 8a introduced between the stamping device 3 and the die unit 4 component 2 in a

hold fixed position and press against the die unit 4. In this case, the hold-down 8 is spring-loaded by spring means 9, not shown. Of the

Hollow stamp 7 is surrounded protectively by the blank holder 8, wherein the central receptacle of the hollow punch 7 a

Bore 8b in the hold-8 is present. The hollow punch 7 merges in the direction of the die unit 4 with a transition 7a into a region which has a smaller diameter

Has outer diameter d3 and engages in the component 2 during forming or this punched.

The hollow ram 7 is internally provided with a punch bore 10 formed as stamp recess, wherein the

Stamp bore 10 is formed centrally in the hollow ram 7 over its entire length. At the rear to the punching waste storage 5 directed end of the hollow punch 7 opens the

Stamp bore 10 in a connecting line 11, via which a punched-out material region from the component 2 and a stamped joint 18 (see Figure 5) can be derived in a storage space 12. The memory space 12 or the

Butzenreservoir is rotational position-independent, because throughout formed circumferentially, and can be externally opened, for example, via a robot movement by means of a sliding outer collar 5a and closed again.

The component 2 is for the production of the collar pass with a first component side or underside on an annular and planar support portion 13 which is provided on the front side of the die unit 4. to

Fixing the position of the component 2 presses opposite to the support area 13 of the contact portion 8a against the component 2 and against the second component side. The hold-down is slightly leading to the hollow punch 7 in the direction of Component 2 moves. This is shown in FIG. 3, according to which the component 2 is clamped in a fixed position between the stamp device 3 or the blank holder 8 and the die unit 4.

Subsequently, the hollow punch 7 hits the component 2 driven and starts to press or punch. This creates a field of tension in the component 2 such. B. in known punching or cutting operations, so that after a penetration depth of the tip of the hollow punch 7 in the component 2 of about one third to half of the material thickness of

Component of the punching slug 18 is released from the component 2. A bending of the component at the beginning of the process takes place

advantageously almost not take place, since initially a pure punching operation is accomplished. A punching blow after the punching of the component is continued by the ongoing

Manufacturing process with the deep drawing or displacement of material of the component 2 in the produced

Collar passage 19 (Figure 5) additionally damped.

Over the entire movement of the hollow punch 7 in the direction of the die unit 4, the collar passage 19

completed. According to Figure 5 shows the produced

Kragendurchzug 19 in the component 2 a protruding edge on the bottom 2a of the component 2. The thus formed edge or dome can be further developed with a modification, if necessary, to a threaded bolt, in which the thread outside

is applied. So can be beneficial otherwise

be welded or pressed threaded bolt replaced, which is significantly more expensive than the

proposed solution with introduced on the protruding edge thread.

The hollow ram 7 moves back after deformation from the Matrizeneinheit in an initial position

(Figure 5), which corresponds to the position immediately before the forming of the component 2 according to Figure 3. The pushed in the manufacture of the collar passage in the punch bore 10

Punch 18 is held therein easily clamped and therefore taken away with the hollow die 7 of the die unit 4. Are already several Stempelbutzen (not shown) by previous punching operations in the punch bore 10th

present, these are pushed together by moving the currently punched Stempelbutzen 18 together.

Central or center of the die unit 4, based on a working or joining axis S in the longitudinal direction of the

Stamping device 3 and the die unit 4, an elongated projecting die mandrel 14 is formed with a cylindrical outer shape, which at its front side to

Stamping device 3 facing the end of a plane

Support surface 14a for the first component side of the component 2 has. The bearing surface 14a likewise supports the component 2 on the underside, wherein the bearing surface 14a lies at least almost in the plane formed by the bearing region 13.

The die mandrel 14 is fixed in position in the die unit 4 and is with its outer diameter di only minimally or slightly smaller than the inner diameter d2 in the front part of the punch bore 10. The relative movement of the hollow punch 7 and die unit 4 according to the invention is possible in one stage or in one stroke and allows the

advantageous embodiment of a collar passage, in particular without sharp edges or burrs on the component 2 in the region of a punched hole 2b.

Particularly advantageous, the proposed die unit 4 is simple in construction, relatively little filigree and thus very robust.

Advantageously, the outer diameter d3 of

Hollow punch 7 in its front region by a double wall thickness D of the formed projecting edge of

Collar passage smaller than an inner diameter d4 of a Matrizenkavität 15. The Matrizenkavität 15 is here

advantageous as a uniform annular gap between the outer region of the die unit 4 and the die mandrel 14

available . The Matrizenkavität 15 is over at least one in particular three distributed over the circumference of the die unit 4 ventilation and / or ventilation line (s) 16 to avoid or

Removal of dirt on the tool 1 is formed.

FIG. 5 shows a variant of the invention

Matrizeneinheit 4, which is the only difference to

Arrangement according to Figures 3 and 4, an anvil 20 which is inserted in the Matrizenkavität 15, and a shoulder 21 in the Matrizenkavität 15 provides. With the paragraph 21, an annular stop surface 20a for the front end of the passage 19 is provided. Thus, a defined edge formation of the passage 19 is defined on the underside of the component 2.

Basically, instead of the rigid or one-piece

Matrizeneinheit 4 also a so-called switchable

Matrix unit can be used in divided construction. This would have the advantage that the two processes of pre-punching and forming, according to the invention simultaneously and without

Switching process can occur, are completely separated from each other and so the applied end force is lower. This would be a little more elaborate or less robust

Make construction necessary. In addition, the process separation would only be "quasi" one-stage, since a comparatively short backward movement of a moving element in the process is necessary and thus a regulated drive is required, in particular an electric drive.
