Definitions
- the invention relates to a method and a device for marking cast parts during the original molding process.
- the first group includes the solution known as a casting watch.
- a casting clock consists of three to five movable concentric rings on which are attached marks - usually numerals - for the calendar day, the month and the shift. The corresponding markings are aligned with a reference mark, making it possible to determine the time of the primary shaping with a resolution down to the layer.
- Such a pouring watch is e.g. described in DE 19958 123 A1.
- a second group of solutions form the direct markers by means of laser or mechanical tools, eg. B. with a needle punch.
- ECC 200 provided and can be identified.
- the applied code is flexibly adjustable. Solutions of this type are proposed in DE 101 53943 A1 or DE 19958123 A1.
- a third set of solutions for marking castings .5 during the forming process is based on a special, fixed cam plate, which is inserted into the mold prior to casting and leaves a one-dimensional impression in the casting.
- the method is based on a positive mold. With this procedure, a continuous marking of the castings is possible, as e.g. is proposed in DE 19925674 A1.
- the invention is therefore based on the object to develop a solution that allows a cost-effective, high-quality and on a wide range of applications within different casting technologies parked tamper-evident mark 30 of castings during the original molding process.
- the dependent claims 2 and 3 and 5 to 9 contain particularly advantageous embodiments of the method according to the invention and the device according to the invention.
- the essence of the method invention consists in the fact that with the direct marking of the castings directly during the casting process both a one-to-one marking and a secure protection against swapping of the workpieces is achieved.
- the method is based on the marking of the castings by means of a matrix code, which is imaged directly during the casting process as a negative mold on the casting.
- the matrix code can be generated by the production planning system of the casting plant, which then also controls the application of the matrix code to the casting. This is done by the process control by positionally variable mechanical means causes the generation of cams or spaces at defined locations of the casting by the fact that within the Gillerformober Assembly cavities for the then to be formed during the casting process on the casting surface cams or not.
- the device is arranged at a defined point of the mold in its surface.
- each individual bit of the code is represented by a position variable mechanical means, such as a displaceable plunger, which is retracted or extended depending on the code generated by the controller and thus during the casting process the formation of a corresponding code cam or a gap on the casting allows.
- the device for generating the matrix code in the form of cams or free spaces is integrated into a device for producing a lost casting mold or a lost casting mold part, for example a sand mold or a sand core so that the matrix code in the production of the lost mold or the lost mold part is introduced at a defined location in the wall of the lost mold or the lost mold part facing the casting of the melt.
- a device for producing a lost casting mold or a lost casting mold part for example a sand mold or a sand core so that the matrix code in the production of the lost mold or the lost mold part is introduced at a defined location in the wall of the lost mold or the lost mold part facing the casting of the melt.
- the device according to the invention for generating the matrix code in the form of cams or free spaces is arranged directly in the wall of the casting mold facing the melt, detachment of the casting by the use of an aluminum-repellent ceramic for the base body and the position-variable mechanical means of the device according to the invention additionally supported.
- the individual position-variable mechanical means can be controlled as marking elements via a flexible system for transmitting mechanical compressive and tensile forces, e.g. Bowden cables, flexible shafts or linkages, which can be generated pneumatically, hydraulically or electromechanically.
- a flexible system for transmitting mechanical compressive and tensile forces e.g. Bowden cables, flexible shafts or linkages, which can be generated pneumatically, hydraulically or electromechanically.
- An advantage of the control by such a flexible mechanical system is that the system for generating force not in the immediate vicinity of the mold, e.g. the mold, must be arranged. As a result, on the one hand reduces the thermal load and on the other reduces the size of the device for marking. The reduced size allows a more flexible use of the marking system on the mold.
- the control of the position-variable mechanical means always takes place only in the unfilled state of the mold, i. without contact to the liquid melt. This ensures that the "greasing" effect known from aluminum casting does not adversely affect the mobility of the variable position mechanical means or blocks the guides, and this effect is enhanced by the air trapped in the apparatus and expanding by the increase in temperature.
- the three-dimensional pattern of the code-bearing cams resulting from the arrangement of the position-variable mechanical means can be easily read in again by means of optical or mechanical methods. It is also possible to provide additional information during further processing of the casting To introduce pieces in this code, for example by removing cams or attaching additional cams by screwing in corresponding pins.
- FIG. 1 shows the plan view of an exemplary code field with cams produced according to the invention
- FIG. 2 the 3-D representation of the cast-off cams according to FIG. 1
- FIG. 3 the schematic representation of a mold with an associated device according to the invention for marking cast parts
- FIG. 4 a detail of a possible detailed construction of the device according to the invention for marking cast parts during the original process.
- Figure 1 shows a code field in which there are 25 molded cams and embody the matrix code containing the necessary marking information for the casting.
- the position-variable mechanical means are designed in the present example as longitudinally displaceable plunger 8.
- said 25 plungers were in a retracted position B within the body 12 of the device like.
- Figure 4 while 9 plunger 8 in the extended position A prevented the formation of cams.
- the upper cam row and the right cam slot serve to synchronize and align the code field.
- FIG. 2 shows the code field in its structure of cams and free spaces in a 3-D representation.
- the device according to the invention for marking cast parts it is possible, for example, to produce a matrix code on an area of approximately 30 ⁇ 30 mm, which corresponds approximately to the area of a classic casting clock, with which up to 2 25 , ie 33554432, different codings are produced can be.
- the cost of a marking device according to the invention are well below the cost of the solutions criticized in the prior art.
- FIG. 3 shows the schematic representation of a mold 6 with an associated device according to the invention for marking cast parts.
- the device according to the invention consists of a marking device 1, which is connected via a flexible power transmission system 2 with a system for generating force 3.
- the power generation system 3 can generate mechanical, hydraulic or pneumatic forces.
- the marking device 1 is arranged within the wall of a mold 6 so that the plunger 8 arranged in it come into contact with the melt 7 located in the mold, for example an aluminum melt, to produce the matrix code.
- the power generation system 3 is in turn controlled by a control system for setting the current mark 4. This in turn is connected to a higher level production planning system 5 and receives its control signals from it.
- the actual force-driven control of the marking device 1 which can be pneumatic, electromagnetic or hydraulic, from the mold 6 and thus from the range of the highest temperatures, i. the melt 7, can be removed.
- the actual control system for setting the current marking 4 does not come into contact with the melt 7 and its high temperatures.
- the division into marking device 1 and drive unit in the form of the force generation system 3 allows a more flexible assembly.
- the marking device has position-variable mechanical means designed as a ram 8 with sliding bodies 9 for guiding the ram 8 as well as connecting pieces 10.
- the connecting pieces 10 are connected to force transmission elements 11.
- the said elements are arranged in a base body 12 with guide, rounded edges and draft, which in turn has a rear stop plate 13.
- the entire marking device 1 or only the plunger 8 and the base body 12 are made of ceramic.
- ceramics were used for this purpose, which are repellent due to their surface finish aluminum, z. B. Monalite, and not wetted.
- the plunger 8 have a diameter of 2.8 mm at a stroke of 3 mm.
- the position B shows a plunger 8 in the retracted state, ie in the rear end position, which leads to the formation of a cam in the code field when filling the mold 6 with the melt 7.
- the coupling of the system for generating force 3 to the superimposed production planning system 5 takes place via an industrial-grade bus system.
