Definitions

  • the invention relates to a stamping unit for attaching markings to components, with a housing and possibly a console carrying the housing.
  • the embossing technique is used in industry, among other things, to identify components with numbers, letters, symbols, stamps and the like. This is often necessary to trace the origin of the production, the batch, etc. In particular, in automotive technology, it is important to determine the manufacturer of the corresponding component, for example, in recall actions or damage findings on motor vehicles.
  • stamps are stamped in or on the component using a stamp tool.
  • This embossing machines are used, for example, apply an embossing force of about 3 to 4 t at about 3 mm large markings to impress the label.
  • embossing pliers are used, which build very large, ie about 0.5 m high and higher, and require a correspondingly strong power drive.
  • Some embossing pliers have a scrollwork, with which the markings to be stamped can be progressively incrementally continued. This embossing process is also referred to as roll embossing.
  • embossing pliers have the disadvantage that a large amount of space on the component to be manufactured and marked is necessary because an embossing pliers requires a lot of space to attack the component can. For smaller sized components or complicated designs, this results in space problems.
  • the roll embossing can also be carried out in the form that the embossing wheel of the embossing unit has distributed at its periphery markings.
  • the embossing wheel moves with very high force over the embossing point of the component. Nevertheless, the embossing unit must still be moved away to the component and the component, so that here too, a large space requirement is necessary.
  • the object is achieved in that in the housing an axially displaceable and pivotable about its longitudinal axis drive shaft is arranged, which is connected at its one end under bias to a drive unit and at its other end has a pressing member, arranged on the housing a marking component exhibiting component is on which the component to be marked can be placed, wherein during the embossing process, the pressure part of the drive shaft with a certain contact pressure against the component to be marked and the marking means having component and pressed on this continuously along and is pivoting and having the identification means Component imprinting the marking in the component.
  • housing is to be understood as meaning both closed and open constructions which have the task of holding or guiding the drive shaft.
  • the axial displaceability of the drive shaft allows movement of the attached to one end of the drive shaft pressure member toward and away from a component to be identified. Furthermore, the pivotability of the drive shaft about its longitudinal axis allows a continuous, i. continuous rolling of the pressure on the component having the marking means on which a component to be marked is placed.
  • Markings are signatures, such as numbers, letters, symbols, stamps and the like to understand that are on or in a to be manufactured or already manufactured component or introduced.
  • the drive shaft is connected at its one end under bias to a drive unit, so that the contact pressure of the pressure wave is fixed to the identification means having component.
  • the housing Since the drive shaft can be made relatively short, the housing has a compact size.
  • the embossing unit so small that these in a clamping device, preferably a positioning device according to DE 20 2006 016 392 and / or a console according to the DE 20 2006 000 908 can be integrated without space problems occur.
  • a clamping device preferably a positioning device according to DE 20 2006 016 392 and / or a console according to the DE 20 2006 000 908 can be integrated without space problems occur.
  • For embossing itself are no other components, such as brackets, feeders, etc. necessary.
  • the component to be embossed is placed over the identifier-containing device, i. it can simply be placed on the component on the housing of the embossing unit.
  • the pressing part of the drive shaft is pressed with a certain contact pressure against the component to be marked and the identification means having component and pivoted on this continuously along.
  • the identification means imprints the marking from below into the component. Thereafter, the provided with the embossed component can also be easily removed again.
  • a stamping should be understood.
  • the invention results in a small compact embossing unit with a low height, which allows a low-power and accurate adjustment an embossing process for components to be marked.
  • the embossing unit can be arbitrarily placed in a manufacturing apparatus, e.g. a welding device, without moving the embossing unit, i. Feeding and driving away to the embossment, is required.
  • the embossing unit is thus always connected in a stationary manner to the production apparatus.
  • the embossing unit can be used because of its compactness even in tight spaces and complicated designs.
  • the identifier is having device designed as a punch holder.
  • the identification means comprises single-part or multi-part stamps, which have numbers, letters, symbols and / or the like, which are preferably formed raised and thus allow embossing.
  • the punch holder may have fixed, interchangeable or self-continuously adjustable or adjustable punches depending on the desired label.
  • the pressure member is arranged transversely to the longitudinal axis of the drive shaft and formed as a shaft, roller or roller. Because the pressure member is disposed directly at one end of the drive shaft and the punch holder in the immediate vicinity of the drive shaft on the housing, the pressure member is very short, so that the contact pressure is completely transferred to the component to be embossed. By defining the shape, width and length of the pressure member can be adjusted depending on the identification form and size of the embossing area.
  • the drive shaft is biased by means of a disc spring package known per se.
  • the bias of the drive shaft for example via a plate spring assembly associated adjusting nut.
  • the drive unit for the drive shaft consists of a drive motor and a transmission.
  • the drive motor may be a pneumatic motor, electric motor or the like, and the transmission may be a worm, gear, rack gear or the like. If If the pressure part is in the zero position before the embossing process, for example, the worm gear driven by the pneumatic motor moves the drive shaft in the axial direction, ie transversely to the punch plane, and then pivots the pressure part over the embossing area and completes the marking of the component. This embossing process takes place in a very short time, eg within 1 or 2 seconds or even fractions of a second.
  • the required pressure force can be kept relatively small with few Newtonmeter drive torque.
  • This relatively low drive energy or pressure force is also sufficient because the continuous, i. continuous rolling of the pressing member, each part of the overall marking, e.g. Number by digit, letter by letter, etc., one after the other.
  • control means are provided for switching on and off of the drive unit and for pivoting the drive shaft towards and away from the identification means having component.
  • control means preferably comprise at least one switching cam formed on the drive shaft and an associated proximity switch which detects the position of the drive shaft.
  • the housing is mounted on a console, a foot part, a hinge or the like, for example on a positioning device according to the DE 20 2006 016 392 and / or a console according to the EN 20 2006 000 908 ,
  • the embossing unit 1 according to the Fig. 1 to 5 has a housing 2, which is connected by way of example with a pivotable holder 3 by means not shown pins.
  • the holder 3 in turn is connected to a foot 4, optionally a bracket, a hinge or a positioning device, which, if necessary, via a Shimsplatte 5, for height positioning the embossing unit is attached to a base plate 6.
  • the embossing unit 1 can thus be placed on a base, not shown, for example, a mounting plate or welding device.
  • FIG. 5 shown view of the embossing unit 1 contains dashed lines, which are intended to illustrate the installation direction of the respective parts of the embossing unit 1. Furthermore, in the Fig. 1 to 4 in each case a component Z to be provided with a marking, that is to be embossed, is shown diagrammatically in dashed-dot-dashed lines.
  • an axially movable and pivotable about its longitudinal axis drive shaft 7 is used, on which at least two spaced ball bearings 8 and two spaced spacer rings 9 are arranged, which are introduced into a housing bore 10.
  • the lower protruding from the housing 2 section 11 of the drive shaft 7 is formed in cross section as a hexagon. This hexagonal section 11 leads with the interposition of a disc spring assembly 12 with an associated adjusting nut 13 in a transmission 14, e.g. a worm gear.
  • a switching cam 15 is fixed, which serves as a control means together with a proximity switch 16 which is fixed to a sensor holder 17.
  • the sensor holder 17 is attached to a holding part 18.
  • This holding part 18 receives in an opening 19 a drive motor 20, for example a pneumatic disk motor, which is mechanically connected to the gear 14.
  • the coupling of the drive shaft 7 with the motor-gear unit 14, 20 is effected in that the holding part 18 is screwed to the housing 2, for example.
  • the drive shaft 7 has at its upper end designed as a roller, shaft or roller short pressure member 21 which projects at right angles from a ball bearing 22 from the longitudinal axis of the drive shaft 7.
  • a pressure plate 23 is fixed, on which a component 24 having a marking means embodied as a punch holder is positioned.
  • the identification means 17 comprises single-part or multi-part stamps not shown in more detail, which have numbers, letters, symbols and / or the like which are raised.
  • the switching cam 15 can be brought into engagement with the proximity switch 16 serving as an initiator, which in turn initiates the switching on of a drive for triggering the embossing process and causes the drive to be switched off when the embossing process has been completed.
  • the pressing force of the drive shaft 7 for the pressure member 21 is generated by the plate spring assembly 12.
  • the press-on part 21 bears against the component Z to be marked, which is placed between the press-on part 21 and the component 24, a pressure is built up by the drive unit 15, 20 and the drive shaft 7 becomes linear, ie axially against that on the marking means
  • Component 24 placed component Z moves and pivots with the pressure member 21 on the embossing point on the component Z, so that the stamp of the marking means having component 24 form a signature in the component Z by their sublime training.
  • the drive shaft 7 moves with the pressure member 21 back to the zero position and provided with the marking component Z can be removed. Because the Embossing unit 1 is advantageously open at the top, the component Z can be easily removed after embossing without an additional positioning unit is necessary.
