Abstract
Description
[0001] The invention relates to a deburring device.
[0002] The production and processing of components with complex geometries places high demands on manufacturing technology. Thin-walled, rotationally symmetrical structures, in particular, which are frequently found in packaging and closure technology, require special machining processes to ensure precise, high-quality surfaces and edges. A particular challenge is the post-processing of edge areas, such as deburring. For example, deep-drawn packaging components can have sharp edges or develop burrs due to cutting processes. Conventional deburring methods often reach their limits in these cases, as thin-walled components are often sensitive to mechanical stress.
[0003] Various approaches to edge processing are known in industrial practice, but these are often limited by technical constraints such as insufficient adaptability to component tolerances or a lack of process stability. At the same time, the demand is increasing for economical and efficient processes that can guarantee consistent quality even at high production volumes.
[0004] The present invention is based on the objective of providing a deburring device that enables the robust deburring of complex components in a simple and cost-effective manner.
[0005] The problem is solved according to the invention by the deburring device according to claim 1. Advantageous embodiments of the deburring device are specified in dependent claims 2 to 9.
[0006] Unless otherwise stated, the terms “radial” and “axial” refer to the rotational relative movement between the body and the cutting tool.
[0007] The invention relates to a deburring device for deburring at least one end edge of a rotationally hollow section of a body that is at least partially rotationally hollow. The deburring device comprises at least one cutting tool with a groove-shaped receiving area for receiving at least one region of the end section of the body, wherein the groove-shaped receiving area forms at least one cutting edge, at least partially, so that at least one edge of a wall of the rotationally hollow section can be deburred by a rotational relative movement between the body and the cutting tool when a region of the rotationally hollow section is positioned in the groove-shaped receiving area. The cutting tool is movably and resiliently mounted in a bearing direction parallel to an opening direction of the groove-shaped receiving area.
[0008] The opening direction of the groove-shaped receiving area can be aligned so that, when a region of the rotationally hollow section of the body is positioned in the groove-shaped receiving area of the cutting tool, it runs parallel to its axis of symmetry and the cutting tool is spring-mounted accordingly in this direction.
[0009] The rotational relative motion can be achieved, for example, around the axis of symmetry of the hollow-body section of the body. Alternatively, the rotational relative motion can be achieved, for example, by rotating the body itself.
[0010] The area of the end-faced rotationally hollow section of the body, which can be received by the groove-shaped receiving area of the cutting tool, can be either an end-faced area of the end-faced rotationally hollow section of the body or an area of the circumference of the end-faced rotationally hollow section.
[0011] The spring-loaded mounting ensures that the groove-shaped receiving area of the cutting tool is always guided at the front face of the body during rotational relative movement and length tolerances of the body, and is engaged there with at least one cutting edge for deburring purposes.
[0012] The section-hollow body can, for example, be a body that is essentially rotationally symmetrical in at least one end section and forms an internal cavity. This can be, for example, an essentially hollow cylindrical or hollow conical section. The entire body may also have an essentially hollow cylindrical or hollow conical shape.
[0013] Optionally, the body includes an end-face element that delimits the rotationally hollow section and closes off the internal cavity of the body on one side. The body can be deburred by the deburring device on a second end face opposite the delimiting element, or on a wall formed therein. The delimiting element can thus form a lid on the rotationally hollow section, with the cavity open on one side. For example, the body could be a bottle stopper, possibly for spirits.
[0014] The wall of the rotationally hollow section of the at least partially rotationally hollow body, which can be deburred by the deburring device, can be, for example, an inner side or inner wall, an outer side or outer wall and / or the end face or end wall of the body.
[0015] The body may be at least partially thin-walled, whereby thin-walled means that the wall thickness of the end-end, hollow-body section is small in relation to its diameter. For example, the wall thickness may be less than 1 / 50 of the diameter.
[0016] For example, a corresponding body in the rotationally hollow section has a diameter between 20 mm and 40 mm, for example 32.7 mm, with a wall thickness between 0.1 mm and 0.4 mm, for example 0.23 mm.
[0017] The groove-shaped receiving area can, for example, be U- or V-shaped.
[0018] The spring-loaded mounting of the cutting tool may be realized or be realizable by a fluid mounting, wherein the deburring device has at least one fluid channel through which fluid can flow to the cutting tool.
[0019] The cutting tool can be held in place by the flow pressure and / or dynamic pressure of the fluid along the bearing direction, whereby the cutting tool is movable along the bearing direction due to length tolerances of the body and the resulting forces acting on the cutting tool. At least when the cutting tool is displaced against the opening direction of the groove-shaped receiving area, the flow pressure and / or dynamic pressure can generate a spring force opposing the displacement.
[0020] If necessary, the flow pressure and / or dynamic pressure increases when the cutting tool is moved against the opening direction, which in turn causes an increase in the spring force.
[0021] Depending on the flow pressure and / or dynamic pressure, such a spring force can also act without any force being applied by the body, thus holding the cutting tool in a stop position along the bearing direction, for example.
[0022] The cutting tool may be pneumatically or hydraulically movable by adjusting the flow pressure and / or back pressure in the bearing direction. Furthermore, the engagement of the cutting edge with the body may be regulated by adjusting the pressure.
[0023] The deburring device may also have a fluid supply opening which is fluidically connected to the fluid channel. The fluid supply opening is designed for external fluid supply.
[0024] Advantageously, the fluid supply opening is equipped with an internal thread, so that a fluid line or a fluid adapter can be connected to the deburring device for the mechanical connection of a fluid line.
[0025] In an advantageous embodiment, the fluid bearing is not designed to be fluid-tight, allowing the fluid to flow through the fluid channel to the cutting tool during a deburring process and to escape at least partially to the outside. The fluid can escape to the outside, for example along the bearing direction, through leaks or play in the spring-loaded bearing of the cutting tool, and / or the deburring device includes fluid discharge openings designed to drain the fluid.
[0026] It is not excluded within the meaning of the invention that in an alternative embodiment the fluid bearing is essentially fluid-tight, with a prevailing static pressure being decisive for the spring bearing.
[0027] Fluid storage can be achieved or made possible by compressed air.
[0028] This means that compressed air is the fluid used for fluid storage.
[0029] The compressed air can have a pressure of, for example, 0.02 MPa to 2 MPa, such as 0.1 MPa.
[0030] Advantageously, the deburring device includes several cutting tools arranged along a circular path.
[0031] The cutting tools are each designed and aligned as described. Consequently, the groove-shaped recesses can at least partially form a circular path or be arranged on this circular path.
[0032] Essentially, the groove centers are located on the circular path, with the respective longitudinal profiles of the groove-shaped receptacles being essentially tangential to the circular path.
[0033] The center of the circular path can advantageously lie on the axis of rotation of the rotary relative motion between the body and the cutting tool.
[0034] Furthermore, the circular path can have the same diameter as the mean diameter of the hollow-body section of the body.
[0035] Advantageously, the cutting tools can be distributed at equal distances along the circular path.
[0036] In one embodiment, the deburring device comprises eight cutting tools arranged at equal intervals at an angle of 45° to each other on a circular path.
[0037] It may be provided that the groove-shaped receiving area of the cutting tool has a groove base and two laterally opposing groove flanks, wherein both the groove base and the two groove flanks form a cutting edge at least partially.
[0038] The cutting edges can be designed in such a way that they do not form a clearance angle.
[0039] The relevant sections of the groove flanks, each forming a cutting edge, can connect directly to the groove base, so that the cutting edges are realized without interruption at the transitions from the groove base to the groove flanks.
[0040] The cutting tool can therefore have a continuous cutting edge formed by the individual cutting edges, which, for example, runs in a U-shape, or it can have a separate cutting edge for each groove base and groove flank.
[0041] A continuous cutting edge or multiple cutting edges at the base of the groove and on both sides of the groove allow a rotationally hollow section of a body to be deburred simultaneously on its inner side or inner wall, on its outer side or outer wall and on its end face or end wall.
[0042] The minimum distance between the groove flanks, and thus potentially the width of the groove base, can be equal to or only slightly greater than the wall thickness of the end-faced, hollow-body section of the body. For example, the width of the groove base can be up to 0.1 mm, such as 0.01 mm, greater than the corresponding wall thickness.
[0043] The cutting edge at the base of the groove can run in a plane that spans between the radial and axial directions. The axial direction runs parallel to the opening direction of the groove-shaped receiving area and corresponds to the axis of rotation of the relative rotational movement.
[0044] Each cutting edge on a groove flank can also run in a plane that spans between the radial and axial directions.
[0045] The deburring device can comprise at least one locking element with at least one recess in which the cutting tool is arranged, wherein the cutting tool has at least one shaped element projecting at an angle to the bearing direction, so that the shaped element can be brought into contact with the locking element during a translational movement of the cutting tool in the bearing direction, thereby limiting the cutting tool in its translational degree of freedom in the bearing direction and securing it against movement out of the locking element.
[0046] The form element can, for example, protrude laterally from the cutting tool perpendicular to the bearing direction or perpendicular to the opening direction.
[0047] The cutting tool may comprise a substantially cuboid base body and an attached structure forming the groove-shaped receiving area. In this case, the forming element may be arranged on the base body.
[0048] For example, the shaped element can extend over the entire length of the cuboid base body. The shaped element can be positioned on a side of the base body facing away from the groove-shaped receiving area.
[0049] In the case of multiple cutting tools arranged on a circular path, the respective shaping elements can protrude laterally in a tangential and / or radial direction.
[0050] In one embodiment, the forming element has a substantially semicircular cross-section, with part of the semicircular surface of the forming element designed to abut the locking element. For example, the forming element can have a diameter of 0.05 mm to 2 mm, such as 0.2 mm.
[0051] The cutting tool may include a cutting tool groove located adjacent to the forming element on the tool body. This cutting tool groove can, for example, serve to drain fluid and prevent the cutting tool from jamming in the bearing direction.
[0052] In an advantageous embodiment, each cutting tool has two shaped elements arranged, for example, on opposite sides of the cutting tool, both of which are designed to rest against the locking element.
[0053] The locking element can, for example, be a substantially cylindrical disc. The recess is a through-opening.
[0054] At least when the form element is placed on the locking element, the section of the cutting tool encompassing the cutting edge, i.e., for example, a structure forming the groove-shaped receiving area, protrudes from the recess of the locking element, so that an area of the rotationally hollow section of the body can be brought into engagement with a cutting edge.
[0055] For example, the locking element can be mechanically connected to another component of the deburring device by means of screw connections.
[0056] The recess in the locking element may include axially extending grooves, which, in the case of fluid bearings, serve to drain fluid. Furthermore, this may also prevent or reduce malfunctions that could be caused by sharp edges of the cutting tool.
[0057] The locking element can fix the cutting tool, at least in the radial direction, insofar as the cutting tool rests against two radially opposite walls of the recess.
[0058] The radial direction refers to the rotational relative movement between the body and the cutting tool, or, when positioning a section of the hollow-body rotational part in the groove-shaped receiving area of the cutting tool, to the axis of rotation of this section of the body.
[0059] If necessary, the walls of the recess and the cutting tool may form radial play or a clearance fit. The cutting tool can then be brought into contact with the walls of the recess by minimal radial movement.
[0060] In the case of several cutting tools arranged on a circular path, the individual cutting tools can be fixed in a radial direction on the circular path by the locking element.
[0061] In an advantageous embodiment, a lateral boundary of at least one fluid channel is realized at least sectionally by the locking element.
[0062] "Lateral" here essentially means perpendicular to the flow direction of the fluid channel. If necessary, the boundary of the fluid channel formed by the retaining element is perpendicular to the flow direction.
[0063] The fluid channel can, for example, be formed by a fluid groove which is closed laterally by the locking element, thus ensuring a flow through the fluid groove in the longitudinal direction.
[0064] In the case of multiple cutting tools, for example, several star-shaped fluid channels can be present, with each fluid channel serving to supply fluid to a cutting tool. The fluid channels can guide the fluid radially outwards from a common central fluid supply line to the respective cutting tool, with the lateral boundary of the fluid channels being realized by a disc-shaped retaining element.
[0065] It is possible that the groove-shaped receiving area of the cutting tool has a centering device formed by at least two opposing insertion ramps which transition into the groove-shaped receiving area.
[0066] The insertion ramps can be realized by the lateral groove flanks of the groove-shaped receiving area.
[0067] The insertion ramps can compensate for runout tolerances of the rotationally hollow section of the body and force the body wall into engagement with the groove-shaped receiving area and its cutting edge or edges.
[0068] The body may be mechanically deformed, for example slightly bent, during this process. The forces acting upon it can support the deburring process.
[0069] The invention enables a deburring method for deburring at least one end edge of a rotationally hollow body section of a rotationally hollow body, in which a described deburring device is provided, a region of the rotationally hollow body section of the body is positioned in the groove-shaped receiving area of the cutting tool of the deburring device, and at least one body edge of a wall of the rotationally hollow body is guided along at least one cutting edge formed at least partially by the groove-shaped receiving area by a rotational relative movement between the body and the cutting tool and thus deburred.
[0070] The spring-loaded mounting of the cutting tool serves the purpose of supporting the cutting tool against a force acting on the cutting tool from the body and / or compensating for axial length tolerances of the body.
[0071] In the case of fluid bearings, fluid can be pumped through at least one fluid channel towards the cutting tool before and / or during the deburring process to ensure the spring effect. The spring force can also be adjusted by modifying the back pressure and / or flow pressure.
[0072] The partially hollow-rotational body can, for example, be a body that is essentially rotationally symmetrical in at least one end section and forms an internal cavity. This can, in particular, be a section that is essentially hollow cylindrical or hollow conical. The entire body may also have an essentially hollow cylindrical or hollow conical shape.
[0073] If necessary, the end-side hollow-body section of the body is pressed into the groove-shaped recess of the cutting tool by a distance of between 0.3 mm and 1 mm, for example 0.7 mm, and thus brought into engagement with the cutting edge.
[0074] The body may be moved into the deburring device by gravity and may also be brought into engagement with the cutting tool or its cutting edge(s) by gravity.
[0075] Furthermore, deburring can be achieved by simultaneously engaging several cutting tools. It is possible for the relative rotation to encompass such a large angle that the area to be deburred on the end-facing, hollow-shaped section of the body is successively guided along several cutting tools and thus deburred. For example, in a deburring device with eight cutting tools, the relative rotation can encompass an angle of rotation between 50° and 75°, such as 65°.
[0076] In an advantageous embodiment, the rotational relative motion is realized by a rotation of the body, optionally around the axis of rotation of the end-end hollow-body section of the body.
[0077] This process can be used to deburr bottle closures, such as those found on liquor bottles. The bottle closure is defined as a partially or fully hollow body. It may have been previously manufactured using a deep-drawing process. The bottle closure may be, or could be, fitted with a screw thread.
[0078] The invention is explained below with reference to the exemplary embodiments illustrated in the accompanying drawings. The invention is in no way limited by the purely schematic drawings, and it should be noted that the exemplary embodiments shown in the drawings are not limited to the dimensions depicted.
[0079] They show Fig. 1: a perspective view of a bottle cap as a body that is at least partially hollow in rotation; Fig. 2: a perspective view of a deburring device; Fig. 3: a top view of the deburring device; Fig. 4: A perspective view of the base plate of the deburring device from Fig. 2 and Fig. 3; Fig. 5: a sectional view of the base plate along the cutting line AA from Fig. 4; Fig. 6: A perspective view of the locking element of the deburring device of Fig. 2 and Fig. 3; Fig. 7: detail B from Fig. 6 in a top view; as well as Fig. 8: A perspective view of a cutting tool of the deburring device of Fig. 2 and Fig. 3.
[0080] Fig. Figure 1 shows a perspective view of a bottle cap 25 as a body 20 that is at least partially hollow in rotation, wherein the bottle cap 25 shown is equipped with a deburring device 1, as described in Fig. 2 and Fig. Figure 3 shows that the body 20 can be deburred at its rotationally hollow section 21. The body 20 has thin walls and a hollow cylindrical section 22 at its end, forming a rotationally hollow section 21. The body 20 also includes an end-face element 23 that delimits the rotationally hollow section 21 and closes off the internal cavity of the body 20 on one side. A ribbed structure 24 is incorporated into the wall of the rotationally hollow section 21.
[0081] In Fig. Figure 2 shows a deburring device 1 in a perspective view. The deburring device 1 comprises a substantially cuboid base plate 30 and a disc-shaped locking element 40, which is attached to the base plate 30 by means of four screw connections 47 arranged on a circular path. The base plate 30 also has a recess into which the locking element 40 is inserted, so that the base plate 30 and the locking element 40 are flush. The locking element 40 is fixed in its angular orientation with respect to the base plate 30 by centering pins 31, 32, the centering pins 31, 32 being each inserted into a centering opening 43, 44 of the locking element 40 for this purpose.The deburring device further comprises eight cutting tools 60 distributed along a circular path, which are arranged in respective recesses 41 of the locking element 40 and are thereby fixed in the radial and tangential directions with respect to the circular path. Each cutting tool 60 is resiliently mounted along the bearing direction 58 by a spring bearing 50 designed as a fluid bearing 51. The bearing direction 58 is axially aligned with respect to the circular path of the arrangement of the cutting tools 60. In addition, a fluid adapter 57 is arranged on the base plate 30, which serves for the fluid connection of a fluid line (not shown) through which, for example, compressed air can be supplied as a fluid to the fluid bearing 51. The end-end hollow cylindrical section 22 of the body 20 is made of... Fig. The part 1 can be deburred by the deburring device 1 shown here, by bringing the hollow cylindrical section 22 into partial engagement with the cutting tools 60 and guiding it along the cutting tools 60 or their cutting edges by a rotary relative movement. The spring-loaded bearing 50 can compensate for axially parallel length tolerances of the body 20 and support the cutting tools 60 against a force acting on the cutting tools 60 from the body 20.
[0082] Fig. Figure 3 shows a top view of the deburring device 1 of Fig. 2. The locking element 40 is attached to the base plate 30 by means of four screw connections 47. The locking element 40 is fixed in its angular orientation relative to the base plate 30 by centering pins 31, 32, the centering pins 31, 32 being inserted for this purpose into centering openings 43, 44 of the locking element 40. The deburring device 1 has a total of eight cutting tools 60, which are distributed at equal intervals along a circular path and each arranged in a recess 41 of the locking element 40. Furthermore, [the figure] shows Fig. 3, that the fluid adapter 57 is arranged on the base plate 30, which serves for the flow-related connection of a fluid line not shown for fluid supply.
[0083] In Fig. 4 is the base plate 30 of the deburring device 1 of Fig. 2 and Fig. Figure 3 shows a perspective view. It can be seen that the base plate 30 has a base plate recess 33 for receiving the locking element (not shown here). The base plate recess 33 also has four screw-in openings 34 through which the locking element can be attached to the base plate 30 by means of screw connections. Furthermore, the base plate 30 includes two centering pins 31, 32 and has eight star-shaped fluid channels 52, designed as fluid grooves 53, which can be laterally delimited by a lateral arrangement of the locking element. The angle between the adjacent fluid channels 52 is always the same. Fluid can be guided from a fluid supply line 54 to cutting tools (not shown here) via the fluid channels 52, thus creating a fluid bearing as a spring-loaded bearing for the cutting tools.The fluid supply line 54 is connected to a fluid supply opening 55 in terms of flow technology.
[0084] Fig. Figure 5 shows a sectional view of the base plate 30 along the section path AA. Fig. 4. The section passes through the base plate recess 33 and two fluid channels 53 designed as fluid grooves 52. The sectional view clearly shows that the fluid channels 52 are fluidically connected to the fluid supply opening 55 via the fluid supply line 54. An internal thread 56 is provided at the fluid supply opening 55, which serves to connect a fluid adapter (not shown here) and thus, if necessary, a fluid line (also not shown here) for supplying fluid.
[0085] In Fig. 6 is the locking element 40 of the deburring device 1 of Fig. 2 and Fig. Figure 3 shows a perspective view. The disc-shaped locking element 40 has four through-holes 46 for fastening to the base plate (not shown). The locking element 40 also includes two centering openings 43, 44 for determining its angular orientation and has a total of eight recesses 41 spaced equally apart along a circular path, designed to accommodate cutting tools (not shown). Centrally located on the circular shape of the locking element 40 is a locking element recess 45. This recess 45 serves to center the deburring device 1, e.g., above / below a spindle with a clamping option for the body 20, in order to ensure low positional tolerance of the body 20 relative to the deburring device 1 and thus guarantee successful deburring.
[0086] Fig. 7 shows detail B from Fig. 6 in a top view. Here, an example of a recess 41 for receiving a cutting tool is shown, wherein the shown shape of the recess 41 applies to all recesses 41 made of Fig. Figure 6 applies. The recess 41 is rectangular and has a recess groove 42 in each of its corners, which facilitates fluid drainage when the cutting tool is inserted and also prevents the cutting tool from jamming in the bearing direction. The bearing direction here runs perpendicular to the plane of the drawing.
[0087] In Fig. 8 is a cutting tool 60 of the deburring device 1 of Fig. 2 and Fig. Figure 3 is shown in a perspective view. The cutting tool 60 comprises a substantially cuboid base body 61 and a superstructure 62 arranged on it.
[0088] The assembly 62 comprises a groove-shaped receiving area 70, which is essentially U-shaped and is formed by a groove base 73 and two opposing groove flanks 71, 72. The first groove flank 71 forms a first cutting edge 74, while the second groove flank 72 forms a second cutting edge 75, and the groove base 73 forms a third cutting edge 76. Thus, a rotationally hollow section of a body can be deburred simultaneously on an end face, as well as on an inner and outer surface, by the engagement of the cutting edges 74, 75, 76. It should be noted that all three cutting edges 74, 75, 76 are only shown in a simplified form in the figure. The opening direction 90 of the groove-shaped receiving area 70 is indicated here by an arrow. Each of the groove flanks 71,72 of the groove-shaped receiving area 70 is followed by an insertion ramp 81,82, which forms a centering device 80.The centering device 80 allows a rotationally hollow section of a body to be deburred to be guided into the groove-shaped receiving area 70. Furthermore, two protruding shaped elements 83, 85 are arranged on the cutting tool 60, specifically on opposite sides of the base body 61. The shaped elements 83, 85 are designed to abut the locking element 40. Fig. 6 is set up to limit one translational degree of freedom of the cutting tool 60 along the bearing direction away from the base plate 30. Each of the form elements 83, 85 also has a cutting tool groove 84, 86 adjacent to it, which facilitates fluid drainage. Reference symbol list 1 Deburring device 20 bodies 21.
