Definitions

  • the object of the invention is a wedge drive for deflecting a vertical pressing force with a driver 1, a slide 2 and a slide holder 3.
  • a preferred object is a horizontal wedge drive.
  • Wedge drives are devices that are used in the automotive industry to machine body parts.
  • the metalworking of body parts and other parts is carried out today in industrial continuous processes. This means that the metal parts have to be manufactured, shaped, punched and machined in a continuous workflow.
  • a large number of different presses, punches and other devices for metalworking are frequently used here.
  • Tools specially made for the body parts and in which wedge drives are installed are used in these presses.
  • the wedge drives process the body parts at any point on the metal part.
  • the wedge drive deflects the vertical working direction into a horizontal working direction in order to be able to carry out lateral operations on body parts if necessary. During this processing, considerable forces act permanently on the wedge drives used.
  • Usual presses work with pressures from 100 t to over 2000 t.
  • wedge drives In a continuous machining process of the metal parts, these forces are permanently loaded on the wedge drives used.
  • the wedge drives must therefore be designed for such an application so that they can withstand these forces for as long as possible without any signs of wear and tear, and furthermore a reproducible, precisely fitting processing of the metal parts is made possible.
  • the slide 2 When the wedge drive is installed in a press, the slide 2 is installed in the lower part of a press tool.
  • the driver 1 is rigidly mounted on the upper part of the tool.
  • the driver 1 When the driver 1 is moved downward, it drives the slider 2, which is in the retracted position, over the slide guide 3 with the wedge bevel of the driver 1 when it sits on the slide 2.
  • the slide 2 When the tool is completely moved together, the slide 2 has reached its end position.
  • the slide is thus able to carry out certain operations such as punched holes on body parts by means of the deflected pressing force.
  • the upper part of the tool moves up and gives the slide 2, which is pulled back by a gas spring, the possibility to return to its original position. Thanks to the use of maintenance-free sliding elements, the slider is still able to transmit enormous press forces even after long running times.
  • the high pressures are absolutely necessary in the automotive industry for the production of body parts. They can vary depending on the thickness of the processed sheet.
  • DE 26 40 318 AI describes a wedge drive for diverting a vertical pressing force into a force acting at an angle for the forming process.
  • This wedge drive consists of a driving wedge on which a vertical force of a corresponding working press acts and a sliding wedge which transfers the force to the horizontal.
  • the driver wedge and the slide wedge either run over a rounded cooperating area or, in a further embodiment, over a roller.
  • Wedge drives known from the prior art have such great disadvantages that they have for the most part not been released for production by the automotive industry. It is therefore still necessary that such wedge drives as One-of-a-kind products must be manufactured. Such custom-made products are cost-intensive and can usually only be used in a special location for which they were designed. Spare parts have to be manufactured individually, so that this fact is also associated with great expenditure of time and money.
  • wedge drives known from the prior art are not able to achieve high press pressures and service lives, such as are required for forming sheet metal parts, for example.
  • the result of this is that, in general, the slides produced in the prior art are not used in sheet metal processing, but rather that one-off production takes place for each use of a wedge drive.
  • a wedge drive which is characterized in that the slide surfaces 8, in which the slide 2 is guided, are arranged in a prism shape and the slide return is carried out by means of a gas pressure spring 5 arranged in the slide 2.
  • gas pressure springs as slide return as an alternative to steel springs has the following advantages. High thrust forces are achieved so that the slide 2 is pushed into its initial position in any case, even if the slide is jammed. This prevents damage to the tool.
  • the use of gas pressure springs also guarantees a long service life, since the gas pressure springs have a considerably longer service life than the return springs made of steel used previously. Furthermore, the installation conditions when using gas pressure springs are so favorable that a compact design is possible and thus a
  • the gas pressure spring can be removed in the tool when installed. It is closed by a plug, which
  • Changing the slide return when the wedge drive is installed has the following advantages. Maintenance times are reduced to a minimum and damage to the wedge drive during installation and removal can be avoided.
  • the use of commercially available gas pressure springs reduces inventory at the end customer.
  • known wedge drives have an inserted spring return train, which is arranged sc, that it can only be changed by dismantling the entire cell drive and dismantling it.
  • a gas pressure spring can be changed in a fraction of the time otherwise required for the keel drives of the prior art.
  • wedge drives today require a service life of around 1 million strokes.
  • Steel springs generally allow a service life of between 250,000 and 300,000 strokes, but gas springs, with the appropriate installation, enable around 1 million strokes.
  • the maintenance work on wedge drives with retaining springs is about 4 times higher than the maintenance work on the wedge drive according to the invention, quite apart from the much more advantageous service life.
  • only the protective plate and the sealing plug have to be milled in order to remove the gas spring.
  • the entire device has to be dismantled and dismantled from the pressing tool, since the inside of the spring is located at a location that is not accessible from the outside.
  • a mounting plate 4 is arranged on the slide 2. This can preferably be removed using fastening screws that are accessible from the rear. This enables the punching and forming standards built on the mounting plate to be easily installed and removed even when the wedge drive is arranged in the tool. The construction of the punching standards is also easier and faster to accomplish on a separate right-angled mounting plate than on the slide 2 itself.
  • the mounting plate makes it possible, for example, to replace broken punching standards in the installed state under the press. This means that if, for example, a punch should break during part 1 production, it can be replaced quickly and easily by completely removing the mounting plate.
  • the wedge drives currently known from the prior art and available on the market are constructed in such a way that the entire wedge drive must be dismantled in any case, because the space in front of the punches is in any case so small that it is not sufficient To loosen screws and pins. A change under the press can therefore not take place, ie the entire press tool, which weighs about 40 t, must be removed from the press just to change the punch.
  • a mounting plate that can be individually adapted by the customer to the conditions in the tool is very well able to remedy the situation. This increases the area of application of the known
  • a cast shoulder 13 is arranged on the side of the slide guide 3 to compensate for the forces acting on the driver 1.
  • the press transfers the pressure to the driver 1, considerable forces occur on the driver.
  • the upper part of the driver 1 in the slide bed is intercepted by a massive cast shoulder 13 against the working pressure h. Due to its massive construction, the cast shoulder 13 is able to completely absorb horizontal forces that occur during the work process. So there is no thrust from the upper part to the lower part of the wedge drive and an exact tool guidance is guaranteed.
  • the cast-on solid cast shoulder is designed in such a way that it can fully absorb the shear forces occurring during the working stroke of the slide.
  • 13 sliding elements 6 are arranged on the shoulder. These sliding elements are preferably made of bronze with the appropriate solid lubricant. The use of these maintenance-free sliding elements increases the service life and reduces the maintenance costs of the wedge drive according to the invention to a minimum. These sliding elements can also be replaced without changing the entire wedge drive.
  • at least one measuring bore is arranged in the side flanges of the slide 2 as a reference and measuring point. The slide 2 is built completely over this bore so that it can be ideally measured and placed in the design drawing using CAD or manual methods. With this measuring hole, the build-up of standard parts on the work surface can easily be measured from the outside.
  • At least one keyway 15 is arranged in the mounting plate 4.
  • the introduction of such a keyway makes it possible for the thrust which arises in the case of punching and form normalies built up on one side to be transferred ideally to the slide 2. This means that the fastening screws only have to perform a pure holding function without being exposed to lateral thrust.
  • a damping element 11 is arranged on the slide 2 in order to intercept the retracting slide.
  • This damping element 11 is preferably made of rubber.
  • the wedge drive according to the invention furthermore has a slide guide 3 which is machined from all sides around it. This makes it possible to let the wedge drive rest on the tool, no matter which side. In this way, the wedge drive can be placed in particularly narrow tool areas against objects existing for constructional reasons, which would otherwise not be possible due to the imprecise external dimensions of the wedge drive.
  • the slide guide 3 in the upper region has two oppositely arranged w edge strips 9 which clasp the slide 2 so that it can only be moved in the working direction.
  • These heating strips 9 are preferably designed as sliding elements.
  • the guide surfaces overlap almost completely between the slide guide / slide and slide / driver. This is achieved in that the travel X of the slide 2 on the slide guide is greater than the travel Y of the slide 2 on the driver 1.
  • the angle between the 5 travel X and Y is 45 to 70 °, preferred 50-70 ° and particularly preferably 55-60 ° and the ratio between X and Y 1.5: 1.
  • the ratio of travel X to travel Y is particularly preferably at least 1.5: 1.
  • FIG. 1 shows a cross section of the wedge trie according to the invention.
  • the driver 1 has an upward screw flange with which it can be mounted on the upper part of a press tool.
  • a sliding element 6 is provided vertically to intercept the thrust generated by the driver slopes.
  • This driver surface which is fitted with a bronze sliding plate with solid lubricant, has an angle which is able to push the actual slide 2 forward.
  • the slide plate is seen upwards, i.e. in the direction of thrust, intercepted against a cast shoulder.
  • the slide 2 runs in the lower guide area on two prismatic sliding elements 8, which are also made of bronze with solid lubricant. These are deep in the central area and sloping upwards in the outer area.
  • the gas pressure spring is able, on the one hand, to use a sealing plug 16 which is screwed into the slide 2 from behind
  • a counterbore is provided for receiving a damping disc 11, which softens the retracting slide 2 against the slide guide 3
  • the surface of the driver 1 is made according to the driver plate in the upper part to the number of degrees, so that it can absorb the entire pressure to be transferred to the press.
  • the slope was designed so that the slide 2 to be driven is slightly slower than the driver 1 in the upper
  • a mounting plate 4 is mounted on the front of the slide 2. This was shouldered against lateral thrusts with the help of a T-shaped groove 17 (not shown).
  • the mounting plate 4 is screwed from behind with generously sized fastening screws, so that one
  • the slide guide 3 5 contains the counterpart to the lower guide of the slide 2, which follows two sliding plates 8 (not shown) arranged in prismatic form.
  • the upper slide guide takes place with the aid of two opposing heating strips 9 which clasp the slide 2 in such a way that it can only be moved in the working direction.
  • bronze sliding plates with solid lubricant are used. A surface was milled into the front of the slide guide 3, against which the gas pressure spring 5 is braced for returning the slide.
  • a massive cast shoulder 13, 5 which in turn is equipped with a sliding plate made of bronze with solid lubricant 6.
  • This shoulder 13 serves to absorb the thrust forces occurring during the work step, the driver 1 located in the upper part being supported against it.
  • the slide guide 3 is mounted with four generously dimensioned fastening screws in the lower part of the tool. All outer edges of the slide 2 have been completely machined so that all the outer surfaces for contacting or also for absorbing various thrust forces, which can occur depending on the working method, can be transferred 5 to the lower part of a tool.
  • At the back of the cast shoulder 13 there is a mounting hole which enables the gas pressure spring 13 to be removed through the shoulder.
  • the gas pressure spring 5 is completely relieved in the rest position of the slide and thus ensures that the slide damping, which intercepts the retracting slide 2 against the slide guide 3, only has to take over the actual swing of the slide 2.
  • the completely relieved gas pressure spring can be easily installed and removed through the mounting hole in the shoulder without the risk of spring preload pressing a holding element.
  • the mounting plate 4 on the front of the slider is used to build up the punching or forming standards.
