Definitions
- the invention relates to an adjustable calibration device according to the preamble of claim 1.
- Calibration devices are used, for example, to ensure the dimensioning of extruded endless profiles, for example pipes.
- a plastic melt is first prepared in an extruder, which is machined by an outlet nozzle, also called a molding tool.
- an outlet nozzle also called a molding tool.
- the desired dimensioning of the endless profile it passes through the aforementioned calibration device after the shaping, in which it is deformed or held with dimensional accuracy.
- This calibration device consists, for example, of a multiplicity of lamellae which are distributed over the circumference on the outside of the tube to be calibrated and are arranged at a distance from one another.
- This calibration device When viewed in the direction of production of the tube, a large number of such lamellar rings are arranged within a calibration station, the individual lamellas of the individual lamellar rings being spaced from one another. This makes it easy to adjust the individual lamellae of the individual ring relative to the Slats of the following wreath or the previous wreath possible.
- the slats can also be combined in segments into a slat block and carried by a holding or actuating structure.
- the holding structure in turn is usually connected in a housing in a radially adjustable manner.
- the assembly of the calibration device is, however, in some cases quite complex.
- the calibration body usually consists of a large number of components to be assembled during assembly, the overall production of which is complex and cost-intensive.
- the object of the present invention is to provide an adjustable calibration device of the type mentioned at the outset, which can be produced and assembled in a simple and inexpensive manner.
- the adjustable calibration basket comprises at least one mounting ring which, arranged in the circumferential direction, has a number of radially running bores corresponding to the number of segment bodies, in which the actuating devices are received.
- the mounting ring or rings are essentially designed to receive the segment bodies and that in addition to the mounting rings mentioned, a large number of further mounting elements is not required.
- the calibration basket is no longer formed as usual by a large number of housing parts. Instead, a large number of such housing parts are replaced by the mounting ring.
- the mounting ring is easy and inexpensive to manufacture.
- the actuating devices of the segment bodies can be easily inserted in the mounting ring.
- the actuating devices can be designed in the form of spindle drives, in which a nut moves a spindle radially outwards or inwards.
- the spindle drive can in turn be designed to be easy to assemble with a spindle sleeve and a spindle rod accommodated therein.
- the spindle sleeve can initially be inserted in the mounting ring or in a dedicated seat.
- the spindle rod can be inserted into the spindle sleeve afterwards.
- actuating devices can also be implemented in many other forms, for example by means of hydraulic or electrical drives.
- two mounting rings are arranged coaxially and axially spaced apart.
- Each segment body then comprises two holding and actuating devices, one of which is inserted into an associated opening of a mounting ring.
- the mounting rings can in turn be fastened to a common construction, for example an inner support and retaining ring, which fixes the mounting rings in relation to one another.
- a common construction for example an inner support and retaining ring, which fixes the mounting rings in relation to one another.
- the bracket and thus the majority of the housing would be formed from the two mounting rings and the inner support and retaining ring.
- a drive ring for adjusting the spindle drives is preferably arranged between the two mounting rings.
- Fig. 3 shows a cross section perpendicular to the longitudinal axis of a calibration basket according to the prior art and Figure 4 shows longitudinal sections through a calibration basket according to the axes A and C as shown in Figure 3.
- a conventional calibration basket is shown schematically in FIGS. 3 and 4 and is briefly explained below - only for later comparison purposes. For the rest, reference is made to DE 103 07 186 A, DE 103 15 125 A, DE 103 23 543 A and DE 103 24475 A for further information.
- the calibration basket 110 comprises 24 lamella segments which are arranged in an approximately tubular housing in the circumferential direction thereof and are held in a radially adjustable manner.
- a calibration device for different pipe diameters can be realized.
- only one diameter is realized with all segment packages.
- Each lamella segment has two actuating devices 112, which are spaced apart in the axial direction of the calibration device and are accommodated in the housing.
- the actuating devices 112 comprise a spindle sleeve and a spindle rod accommodated therein, which is clamped to the spindle sleeve by means of screws.
- a drive wheel 136 is arranged coaxially and rotatably between the two rows of actuating devices 112 (see FIG. 4).
- the drive wheel 136 has a toothing on the side and meshes with spindle nuts provided on the actuating devices for radial adjustment of the lamella segments.
- a disadvantage of this conventional construction is the large number of holding structures, namely in the present case a first holding ring 140, a second holding ring 142, a clamp-like inner holder 150 and and lateral holding ring 160. These elements together result with other elements result in the essentially tubular housing. This complex structure poses a certain challenge, particularly when assembling a calibration device. In addition, the production of the large number of different individual parts has proven to be particularly cost-intensive.
- the core component here are the two mounting rings 11, which in the present case each have 12 bores which serve to accommodate the actuating devices 12.
- lamella segments 24 (here six pieces) are arranged to form a calibration surface, namely in the circumferential direction, that is to say circularly, and at least partially overlapping. Due to the radial adjustment of the lamella segments 24, calibration openings with different diameters can be created.
- the lamella segments are each held adjustably with two mounting and actuation devices 12, the actuation devices 12 in the present case comprising a spindle rod 18 and a spindle sleeve 16, as in the prior art.
- the lamellar segments 24 are fastened radially on the inside on the spindle rod 18.
- the spindle rods 18 are accommodated in the respectively assigned spindle sleeves 16 and are not only fixable but also adjustable via an adjusting and adjusting screw 32.
- the spindle sleeve 18 has, at least in the lower part, an external thread which interacts with a spindle nut 22.
- a spindle nut 22 By turning the spindle nut 22, the spindle sleeve and thus the spindle rod and also the lamellar segments 24 are moved radially inwards or outwards.
- the spindle sleeve 16 is received and held in its own spindle seat 20, which in turn is inserted (eg screwed in) in the bores of the mounting ring.
- the actuating device is covered by a housing 30.
- An annular support and holder 26 is arranged radially within the spindle nuts 22.
- spindle nuts 22 are rotatably supported and held for each mounting ring 11. Overall, the spindle nuts 22 are thus fixed between the tubular support 26 and the respective mounting ring 11.
- the two of the mounting rings shown in section in Figure 1 are axially spaced and arranged coaxially to each other.
- the two mounting rings 11 are connected to the support and retaining ring 26 via screw connections, not shown.
- the support and retaining ring 26 thus also takes on the task of fixing the two mounting rings 11 to one another.
- a vacuum suction device is connected to the calibration device 10 in FIG. 2, but is only shown partially and schematically.
- a drive wheel 36 is arranged coaxially between the mounting rings and has teeth on its lateral edges. With these toothings, the drive wheel 36 meshes with the twelve spindle nuts arranged on the left in FIG. 2 and the 12 on the right in FIG. 2.
- all actuating devices 12 can be operated simultaneously in the same way and all spindles can be adjusted identically radially inwards or outwards.
- the calibration device essentially also has the two mounting rings, the drive wheel and the tubular support 26.
- recesses are also provided in the mounting rings 11. In addition, material can be saved with these recesses and the manufacturing costs can be further reduced.
