Definitions
- the invention relates to a method and a device for the production of die-cast parts, in particular of parts of aluminum or magnesium materials.
- the invention particularly relates the production of rims or wheels for the vehicle industry.
- Rims or wheels for vehicles, especially motor vehicles, are today after the low-pressure casting process made of aluminum materials. It acts These are usually simply controlled low-pressure casting machines with high manual Working interest. Every machine requires an operator who can handle both the high temperatures the molten metal and the exhaust gases of the casting process is exposed. The demolding of the cast parts is expensive.
- the manufacturer (Niederdruckgiesser) buys the required aluminum alloy in bar form and melts them in melting furnaces next to the low-pressure casting machine, i.e.
- the quality can also vary from machine to machine.
- Light metals in low-pressure casting consisting essentially of a crucible for keeping the melt hot, a mold arranged above the crucible as well as an emanating from the mold, the lid of the crucible protruding and protruding into the melt riser, which by pouring
- the metal consumed in the molded part is charged into the casting machine according to DE-C-3619525. It is characterized in that before each casting a metal block (Ingot) of a casting weight substantially corresponding mass in the gas space introduced above the bath level of the casting machine and before or after the Pulling or ejecting the casting introduced into the bath of the casting machine becomes.
- DE-C-195 38 243 discloses a method for producing a semi-molten one Thixogiess casting material in the thixogistic material, comprising an outer layer portion with dendrites around an outer periphery of a Main body section around, is subjected to a heat treatment to a semi-molten casting material with coexistent solid and liquid phases to create.
- the dendrites, resp. Dendrite fragments by elevation the temperature of the outer layer portion with respect to the main body portion in transformed spherical solid phases, and the outer layer portion in a semi-molten State brought.
- EP-A-710 515 describes a thixocasting process of wheels with a rheocast alloy and a device for this, in which a robot is used.
- the invention is therefore based on the object, a process for the preparation of To develop die cast parts, in particular of wheels or rims for vehicles, with which the disadvantages of the prior art can be overcome.
- a process for the preparation of To develop die cast parts, in particular of wheels or rims for vehicles with which the disadvantages of the prior art can be overcome.
- the environmental impact should be significantly reduced, in conjunction with improved working conditions.
- a die casting machine, handling equipment and control devices are integrated heaters, which are also a gradual Heating bolts of aluminum materials outside the die casting machine allow (possibly also of magnesium materials), which then without appreciable Contact the ambient air into the die casting machine.
- Another object of the invention is to provide a casting device according to claim 4 for carrying out the method.
- the casting equipment is considered automated Casting cell formed and has variable shapes and inserts of the forms, wherein ejector elements are provided which are at the same time functional elements.
- the casting cell includes a die casting machine 1 with a mold, a converter for the heating system 2, a monitor 3, a removal robot 5 for parts removal with a control unit 5, a loading robot 6 for Slugzu Entry with control unit. 7 and a spray robot 8 with control unit 9. Also provided are facilities mold temperature control 10, cooling stations 11 and 13, electrical, e.g. inductive heating units 12 for heating Slugs (bolts), a device for parts inspection ago a conveyor belt 16 for the discharge of non-quality parts and another Conveyor 15 for discharging the good parts. Provided are still a metal supply (Sluglager 17), an automatic cleaning station 18 and a manual cleaning station 20 for Giessmaschine, a balance 19 and a repair area 21st
- the die casting machine 1 are fed directly to slugs or bolts or portions previously were heated in the heating units 12. You can directly and under exclusion of air in the Giesshunt the die casting machine 1 are transferred.
- the Containers are closed with a lid so that the slugs are already heated in these be and upon reaching the desired temperature from the heating unit 12 to the casting chamber without Protective gas can be supplied.
- the container is provided with a lid which can be lifted off can be or is hinged to the container.
- the lid or the bottom of the container can also with a additional and closable opening for a pressure or vacuum emptying provided be.
- the container may be rather flat or tall and narrow.
- a complete Adaptation of the container to the shape of the material portion is not required, although a As low as possible air volume in the closed container is advantageous. In particular, should only a small air gap between the lid and the material surface (portion) be given. A achievable by shaping and weight of the lid tightness is usually sufficient. In semi-solid materials, the emptying of the container is simply over the edge of the container.
- the supply of the bolts also directly from a heated staging space / supply channel out, which may also be directly connected to the casting chamber can, if necessary, during the transfer, the temperature can be increased even more can.
- a heated staging space / supply channel out which may also be directly connected to the casting chamber can, if necessary, during the transfer, the temperature can be increased even more can.
- aluminum materials e.g. preferably an alloy no. A357 (Al-Si7Mg0.6) used to quench and outsource the cast parts with less Time required (T5 treatment).
- T5 treatment Time required
- the heating before casting takes place gradually. This can be divided into three areas. A high-power warming at the beginning, a "cooking" after reaching the thixotropic structure in the mantle area of the bolt and in a Homogenization for final setting of globulithic structure in the starting material.
- the individual bolts can also be "packaged" in foil before heating, preferably in an aluminum foil to avoid oxide formation, etc. Likewise Shielding gas can be used to prevent the oxide formation.
- the starting material of the slugs is a homogeneously distributed, fine-grained material Consider, which by the heating process a uniformly distributed, globular microstructure with Komfechen about 50-100 microns forms.
- the latter is for e.g. qualitatively high-quality wheels or rims, which are produced according to an SSM procedure should, required.
- the molds and casting tools have a modular structure, so cost-effective per type of wheel and simply exchangeable mold packages are given. A quick change for the respective shaping part of the forms is possible.
- the mold in the die casting machine 1 is e.g. two-part or three-part and variable use. Since the rim bed per wheel dimension remains unchanged, only two have Mold plates can be adapted to different front design. These can still Inserts that consist of a cheap and less high-strength material. Thus, the life of such inserts can be adapted to the required number of shots and only the basic form must be made of high-strength material.
- the mold plates can contain slide inserts, which in defined areas adjustable heights and widths in front design (depending on tire and rim dimensions) allow, so not for each dimension an extra shape is needed.
- the fixed mold frame 30 is connected in a conventional manner with the casting chamber 34.
- He also has part-specific core elements for holes in the hub 36 of the wheel 35, which can serve as ejector elements of the wheel 35 at the same time.
- no additional ejectors are needed, but functional parts are used which are already required for other tasks (here as a core element).
- the filling of the casting mold takes place from the hub 36 of the wheel 35 and between the hub surface and the gate 37 of the casting chamber 34 there is arranged as insert a filter 38 supported on the hub 36, which serves primarily to seal the oxide skins of the SSM to be pressed.
- the screen 38 is a stamped part made of aluminum or steel and perforated according to the hub surface.
- the bolts, not shown, are heated and supplied O 2 -arm.
- the filling in the mold cavity is wh obtainst dry, ie without lubricant. Due to the sieve can be dispensed with a shearing knife for the oxide skin of the bolt.
- Casting chamber 34 and casting piston of the die casting machine 1 are preferably made a ceramic material to avoid the use of lubricants and sprays to be able to.
- the moldings or slide 32 are with, not shown, drives and guides provided to ensure a retraction and extension of the moldings or slide 32.
- Corresponding counter-contours are formed in the movable mold frame 33.
- the surfaces for locking the slider 32 are preferably located on the or in the fixed mold frame 30 and more preferably in a line.
- the surfaces to Form centering are independent of the number of moldings or slide 32 formum secured.
- the molds or sliders 32 are suitable for the common range of wheel sizes (e.g. from 13 "to 22") and can be arranged in a single set of mold frames 30, 33 become.
