Description

The invention relates to a device for joining two components with a stamping unit having a blank holder, an inner punch and an outer punch and a die arranged below the punch unit with an anvil axially displaceably arranged within the die in a joining direction, wherein the first component of the stamp unit and the second Facing component of the die facing and can be punched out during the joining by the interaction of male and female punches in the second component and the punched out material after production of the joint forming a recorded in the die slug, which by an axial displacement of the anvil in Direction of the stamp unit is ejected from the die.

Such a device is for Schneidclinchen example of the DE 10 2016 008 580 A1 known. The method described therein is used for forming-technical joining of art-identical materials without auxiliary joining part. In a combined process, a frictional and positive connection is produced by the indirect shear cutting of the low-ductility material on the matrix side and the back-flow of the cut-out hole through the die-side material. When Schneidclinchen the anvil is pushed against a spring down in the known method. When the stamp unit is subsequently moved back, the anvil elastically springs back and pushes the slug out of the die. The ejection of the Butzens is characterized temporally uncontrollable and it is a correspondingly high design effort necessary to ensure that the ejected from the die slugs is selectively dissipated and not fly around uncontrollably.

On this basis, the device described above is to be improved.

To solve the problem is provided in a generic device that a wedge or a lock slider, which has an effective in the joining direction stage in its longitudinal direction, serves as an adjusting means for the anvil, so that the anvil from a first lower position, in which he Joining the two components forms necessary Matrizenboden, in a second upper position axially over an edge of the matrices protruding pushed, and there is provided a positionable means for sucking the Butzens.

By this configuration, the ejection of the Butzens can be controlled, in particular by the anvil is displaced by the actuating means only when the suction device has been brought into position. The design effort is reduced because a suitably sized suction can be brought into its optimal position. A flying around the Butzens during ejection is thereby reliably prevented.

To move the anvil when clinching by means of a wedge or a stepped slider to adjust the penetration depth is from the EP 2 843 910 A2 known. For clinching the device described in this document is not suitable.

Preferably, the adjusting means is power-operated. A pneumatic or hydraulic cylinder and a servo motor can then be used for the displacement.

If the adjusting means is displaceable transversely to the joining direction, the joining forces in the housing surrounding the die can be absorbed, so that the drive for the actuating means need not be able to apply these forces.

Preferably, the die consists of at least two die segments, which are in particular preferably mounted in a surrounding, upwardly open jacket sleeve.

The clinching device consists essentially of the c-shaped bow 100 which in its upper section is a stamp unit 1 and in its lower section one in a housing 40 arranged die 2 with one inside the matrix 2 in a joining direction F axially displaceable arranged anvil 3 having. The stamp unit 1 consists of a three-part housing 1.2 whose lower part 1.9 on the upper part 1.10 can be screwed on. The inner part 1.8 is about several screws 1.7 with the upper part 1.10 screwed. In the case 1.2 are nested and arranged coaxially with each other a hold-down 1.5 an outside stamp 1.4 and an inner stamp 1.3 arranged. The outside stamp 1.4 can be opposite the inner stamp 1.3 in the vertical direction (in and against the joining direction F ) move. The outer stamp 1.4 gets from the hold down 1.5 Surrounded, facing the outer temple 1.4 in the vertical direction (in and against the joining direction F ) can move.

The matrix 2 consists of several die segments 2.1 . 2.2 in a housing 1.2 are arranged. Within the matrix 2 is the anvil 3 in the vertical direction (joining direction F ) arranged displaceably. The displacement of the anvil 3 via the adjusting means 4 as a wedge 4.1 is formed, and transverse to the joining direction F in the case 1.2 slidably arranged. About a compressed air cylinder 30 becomes the actuating means 4 postponed. The adjusting agent 4 can also be used as a stepped control slide 4.2 with a joining direction F acting stage 4.2.1 ( 11 ), thereby forming a lower and an upper position for the anvil 3 to be able to realize.

To connect the two components 10 . 20 For example, which are sheets, these are arranged so that the component 20 with the lower ductility of the die 2 and the other component 10 the stamp unit 1 assigned. To enforce insertion, the stamp unit 1 to the upper component 10 created and the lower component 20 lies on the matrix 2 at. Will the stamp unit 1 continued to drive, affects the components 10 . 20 that of the driven ram 6 applied joining force. The hold down 1.5 is doing in the case 1.2 the stamp unit 1 pushed in, while the outside stamp 1.4 and the inner stamp 1.3 continue in the direction of the components 10 . 20 to be driven. Upon reaching a certain force, the outer punch pushes 1.4 against the force of the compression spring 1.1 in the interior of the case 1.2 one, while the inner stamp 1.3 continue on the components 10 . 20 to drive and in the component 20 a hole 20.1 punched, then the clinching is made by moving further into the die 2 retracts. The punching the hole 20.1 resulting slugs 20.2 is in the matrix 2 held (cf. 8th ). In the stamp-side component 10 no hole is punched, but it is by the penetration of the material (instead of a Butzens) of the undercut in the hole 20.1 of the die-side component 20 educated. After completion of the joining process, the stamp unit 1 against the joining direction F moved back and set up 50 for sucking the Butzens 20.2 from her in 12 shown rest position in the in 13 Positioned functional analysis in position. Then the adjusting agent 4 by means of the pneumatic cylinder 30 moved to the left on the drawing so that the anvil 3 against the joining direction F is pushed either steadily or stepped up while the slug 20.2 ejects, then from the suction device 50 sucked off and disposed of in a manner not shown here.
