Description

[0001] The invention relates to a quill slide for mounting in a multi-part tool in the form of a slide unit with an upper part and a retainer, wherein the quill slide comprises at least one quill. The invention further relates to a tool with at least two tool parts in the form of a slide unit with an upper part and a retainer, and with at least one such quill slide.

[0002] Quill slides are known in a wide variety of applications and designs. A quill serves to hold and move a machining tool, such as a punching tool, with movement occurring in the longitudinal direction, i.e., axially. This movement is effected by a quill driver. To prevent unintentional deflection of the quill, it typically runs in a quill holder. The quill driver and quill holder are usually permanently integrated into the tool or are components of it.

[0003] Pin slides are known, for example, from WO 2007 / 006 161 A1. This patent discloses a molding device for the production of V-engine blocks, particularly in a die-casting machine with a fixed and a movable mold half, wherein the movable mold half contains slides and ejectors, as well as pin slides arranged at an angle to each other and a support plate for supporting the pin slides, which are supported on a support surface that is received perpendicularly by a support plate and arranged relative to the pin slides. The slides and pin slides are actuated by two-way hydraulic cylinders.

[0004] DE 101 53 721 C5 discloses a casting tool for cylinder crankcases, which is constructed from at least two tool parts that, in the closed state, form a mold cavity in the shape of the crankcase. The tool has several slides for demolding cavities and bores. For creating the cylinder bores, the casting tool includes cylindrical quills. The quills can be part of a slide, i.e., in the form of quill slides, e.g., in V-engines, or rigidly fixed in the mold cavity, as, for example, in inline engines. The quills extend through the casting tool from a cylinder head-side wall to a crankshaft-side wall. Cylinder liners are mounted on the quills, which subsequently form at least part of the cylinder bore surfaces.

[0005] From DE 10 2006 016 078 A1, a die-casting mold is known as a component of a casting machine for producing V-shaped cylinder blocks for engines. The mold has quill slides on the ejector side, which in turn are arranged in a V-shape relative to each other. The quill slides are mechanically coupled to the ejector of the casting machine and can be adjusted by the ejector into the casting or injection position. A first mold part is coupled to the ejector on the machine side and, in the form of a mounting plate, has V-shaped guides for the quill slide shafts that are arranged relative to each other and converge towards the cavity of the mold. In the casting position, the head of the quill slide protrudes from these guides. In the ejection position, the heads of the quill slides are retracted into the guides. At the ends facing away from the cavity, the quill slide shafts have guide pins or...Drive components engage in guides of guide rails. The latter are attached to the machine-side ejector and adjustable together with it.

[0006] German patent DE 23 14 908 A discloses an auxiliary device for universal tool milling machines for planing shapes, dies, and electrodes for electrical discharge machining (EDM). The auxiliary device consists of a cast housing in which the work slide, with a swiveling tool holder, moves up and down in a prismatic guide. Alternatively, it has a long cylindrical bore in which a quill in the form of a piston rod performs the stroke movements, and the rotatable tool holder is provided at the lower end of the quill. To prevent the quill from rotating axially, a groove is machined along its entire length (coaxially), and it is guided by a wedge fixed in the housing. In this device, an actuating cylinder is provided on the upper cover, which secures the piston rod in the quill. A bearing point for the shaft projects from the bottom.

[0007] CH 597 959 A discloses a universal device on a fully automatic cam-controlled drilling machine equipped with a two-spindle drill head and an automatic rotary table or sliding table. The two-spindle drill head is mounted on its extendable spindle or quill. This drill head is equipped with two independently operable twist drills. It can also be equipped with other machining tools.

[0008] DE 30 18 445 A1 discloses a thread-cutting device with a drive shaft rotatably mounted in a frame, which is connected to a drive unit movable in opposite directions to move a tool holder for a tap along a helical path. The tool holder is located at the end of a work spindle, which engages with a quill via a lead nut and is rotaryally connected to the drive shaft via a gearbox. The quill is provided in a control head that is interchangeably mounted on the frame, and the lead nut is interchangeably arranged at the end of the work spindle opposite the tool holder. When changing to taps of different sizes, the interchangeable control head allows the lead nut and quill to be replaced with a control head for a different tap size.The control head thus features the quill into which the lead nut engages, which is attached to the upper end of the work spindle. The lead nut and quill form a screw connection with a predetermined pitch. The corresponding lead nut is then attached to the work spindle.

[0009] DE 35 00 003 A1 discloses a spindle drive component with a travel quill for machine tools, wherein the work spindle, including its bearings, is installed in a spindle bearing assembly on the working side of the travel quill. The work spindle is driven by the hollow shaft from the spindle gearbox, which is flanged to the other end of the quill. The travel quill is slidably mounted in a guide cylinder and is moved back and forth within the guide cylinder by its respective feed stroke. A feed motor is mounted on the cylinder, and the motorized feed of the travel quill is effected via a feed lead screw and a nut attached to the gearbox-side end of the quill.

[0010] From EP 0 437 688 A2, a quill with external teeth is also known, wherein a slide, moved up and down by means of an eccentric of a gear unit, with a rack-like toothing engages in a gear which in turn meshes with the toothing of the quill of a vertical spindle of a milling machine. This causes the quill to perform a continuous upward and downward stroke, so that the milling machine can be used as a polishing machine.

[0011] VDI Guideline No. 3386, "Wedge Drives in Large Stamping Tools," published by the Association of German Engineers (VDI) in Düsseldorf in November 1990 (pages 1 to 12), discloses wedge drives in large stamping tools. These wedge drive tools are used when an operation is not performed in the stroke direction of the press ram or when several operations in different directions are to be combined into a single operation. The wedge drive consists of a driver and a slide. The driver redirects the press force and movement to the slide, which performs the actual operation. The driver can also forcefully return the slide to its original position. However, this has the disadvantage that the wedge drive can be damaged if the slide jams. The most reliable way to return the slide to its original position is by spring force or pressure.For a driver used for non-forced slide retraction and where the slide is located in the hold-down, the driver is attached to the upper part. The hold-down must rest on at least three centering cones. The slide must be equipped with forced retraction. A driver for forced slide retraction can simultaneously function as a forced retractor. The connection between the driver and the upper part of the tool must be designed to incorporate a predetermined breaking point.

[0012] US 5,419,225 A discloses a punch comprising a punch body, a punch driver attached to the punch body, and a punch head provided on an upper section of the punch driver, which serves to move relative to the punch driver once the punch head is actuated by a firing pin. The punch further comprises a punch guide fitted into the punch body, a stripper plate arranged on a lower section of the punch guide, a stripper spring between the punch guide and a flanged section of the punch driver, and an elastically deformable damping element between an upper surface of the punch driver and a lower surface of the punch head.

[0013] US Patent 4,989,484 A discloses a punching arrangement for a stamping press, comprising an outer housing or sleeve with a punch slidably mounted therein, a spring for flexibly aligning the punch toward one end of the sleeve, and a removable stripper plate positioned on the sleeve around the working end of the punch. The punch is positively engaged with the sleeve at more than one point, and the stripper plate guides the punch to prevent rotation as well as lateral deflection. A retaining element, such as a ring, surrounds the stripper plate and can be manually actuated to allow the punch and stripper plate to be ejected by a spring.

[0014] DE 20 2009 002 418 U1 discloses a punching tool with a punch for forming a punched hole in a workpiece, a guide housing in which the punch is guided along a punching displacement movement, wherein the punch has a punching part and a head part which is connected to the punching part via a screw connection, wherein the length of the punch between a head end wall and a punching surface closing the end face of the punching part is adjustable via a screw depth of the screw connection, wherein a release element freely accessible from outside the guide housing is displaceable between a locking position in which the screw connection is blocked and a screw position in which the screw connection is released.

[0015] US Patent 4,440,052 A discloses a punching arrangement comprising a punch, a stripper spring assembly, and a punch guide for use in a high-speed punching machine, such as a high-speed turret punching machine. The punching machine includes a die, a punching assembly, a lower die, and a workpiece that is inserted between the punching assembly and the lower die. The die exerts a downward force on the punch. The punch is slidably mounted in a punch guide, which in turn is mounted in a lifting device that generates an upward reaction force as soon as the head of the unitary stripper spring assembly is acted upon by the die, to move the punch downward. The lifting device is provided with a suitable spring for lifting the punching assembly and lifting device away from the workpiece after the punching operation.

[0016] DE 20 2006 001 934 U1 discloses a punching device with a guide sleeve that is at least partially hollow cylindrical, in which a punch driver and a punch are each slidably guided. The punch driver and the punch are connected to each other at their end faces via corresponding threaded sections and their distance from each other is adjustable, the punch being arranged in the guide sleeve so as to be rotationally fixed and axially displaceable. The punch driver is also arranged in the guide sleeve in a defined axial position. It is associated with a releasable locking device to prevent rotation, the locking mechanism acting between the guide sleeve and the punch driver.The punch driver is secured in the guide sleeve by an O-ring. This O-ring, positioned within a corresponding annular groove on the inner circumference of the guide sleeve, allows for rotation and creates a slight detent. This detent can be released by applying slightly more force to both parts. Similarly, the punch has an axial longitudinal groove along its outer surface into which a guide pin engages. This guide pin is held in the guide sleeve by an interference fit. This design allows the punch to be moved only in the axial direction and prevents it from rotating.

[0017] From DE 197 53 549 A1 a wedge drive for deflecting a vertical pressing force is known, comprising a driver, a slide and a slide receptacle, wherein the driver has a prismatic guide, the travel distance Y of the slide on the driver is smaller than the travel distance X of the slide on the slide receptacle and wherein the angle between travel distance Y and travel distance X is 45 to 70°.

[0018] DE 20 2011 108 083 U1 discloses a device with a means for adjusting a guide clearance between a clamp-like device and at least one guide surface on a first part of the device, in which the clamp-like device engages this first part and a second part with a first surface and with a second surface on the second part, wherein the two parts are arranged adjacent to each other and are movable relative to each other. Two wedge-shaped or trapezoidal wear parts are provided between the two parts of the device, wherein these wear parts bear against surfaces arranged at an angle to each other on at least one of the two parts, and the two wear parts are arranged at a distance from each other between the two parts, connected to each other via an adjusting device, and adjustable relative to each other via this device, so that the at least one guide surface of the first part comes into contact with the clamp-like device.

[0019] DE 43 34 417 A1 discloses a press tool for punching holes, comprising a lower part, a device forming a hollow bore in the upper or lower part with the function of a female form, a cheek inserted between the lower and upper parts to hold a workpiece between the cheek and the female form against the lower part when the upper part is moved against the lower part, the cheek having an insert hole passing through it which is coaxial with and opposite the hollow bore, and a punch with a projecting tip which is inserted through the insert hole such that the projecting tip is coaxial with the hollow bore. The press tool further comprises a punch device for driving the punch against the workpiece to drive the projecting tip into the hollow bore with clearance and thereby perform the punching operation on the workpiece.A tubular elastic component is inserted into the insertion hole and receives the punch driven in under force, so that the component comes to lie between the punch and the inner wall of the insertion hole.

[0020] Thus, a wide variety of designs for quills and their associated quill receptacles are known. In the aforementioned prior art solutions, the quills are each secured by various elements within a tool that typically consists of several parts. In every case, a special design and machining of the elements of the respective tools that receive and surround the quill is required.

[0021] The present invention is therefore based on the objective of designing the quill slide in such a way that the machining of the tool or its upper part and hold-down is significantly reduced compared to the prior art, and thus the setup times for installing the quill slide in the tool or for replacing the quill slide are significantly reduced compared to the prior art.

[0022] The problem is solved for a quill slide according to the preamble of claim 1 in that the quill slide is designed as a quill slide unit comprising the quill, at least one quill driver attachable in a first tool part in the form of the upper part, at least one quill receptacle surrounding the quill and attachable in a second tool part in the form of the hold-down, and at least one device connecting the quill and quill driver, wherein the connecting device is at least one clamping element, wherein

[0023] The quill driver, quill, quill receptacle, and at least one connecting element in the form of at least one clamping element are connected to the quill slide unit, and wherein at least one anti-rotation device, engaging with or interlocking with the quill, is provided to prevent rotation of the quill, in order to effectively prevent rotation of the quill as it moves relative to the quill receptacle. For a tool with at least two tool parts in the form of a slide unit with an upper part and a hold-down, the problem is solved by providing a quill slide designed as a quill slide unit, as defined above, wherein the quill driver of the quill slide unit is attached to the first tool part in the form of the upper part, and the quill receptacle is attached to the second tool part in the form of the hold-down. Further developments of the invention are defined in the dependent claims.

[0024] This results in the quill slide being designed as a prefabricated quill slide unit, which is arranged and secured as a complete component within the multi-part tool. Accordingly, the at least two tool parts of the multi-part tool only need to be designed to accommodate the quill slide unit, i.e., the quill receptacle on the one hand and the quill driver on the other. The complete quill slide unit is installed as a single component in the first and second tool parts, so that the first tool part only includes a receptacle for the quill driver and the second tool part a receptacle for the quill receptacle. Advantageously, the quill driver and quill receptacle are also secured within their respective tool parts.Since no further measures are required, in particular no fine adjustments to the tool parts, quick and uncomplicated installation and removal of the quill slide unit into a tool or its tool parts is possible by providing the quill slide unit according to the invention.

[0025] Such a quill slide unit can be used in a wide variety of tools and in various mounting positions, making it highly versatile. Consequently, the costs of equipping a tool with a quill slide are reduced by using this quill slide unit, as no individual design of the quill slide unit is required. Instead, an assortment of differently sized quill slide units can be stocked and installed and used in any tool as needed. This results in a significant cost reduction compared to the individual design of a conventional quill slide.

[0026] At least one anti-rotation device, which engages the quill in a positive-locking manner or interlocks with it, is provided to prevent the quill slide from rotating. To create the anti-rotation device, it is particularly advantageous for the quill to be provided on its outer surface with at least one recess or groove, and for at least one locking element to engage or interlock in the recess or groove of the quill to be provided. The locking element can also be fixed in the quill receptacle. Such an anti-rotation device effectively prevents unintentional rotation of the quill during its up and down movement. This is particularly effective when the locking element engages or interlocks with the quill. Advantageously, the locking element is positively received in an opening of the quill receptacle and also engages the recess or groove of the quill in a positive-locking manner.The locking element engages positively in the recess or groove of the quill. Advantageously, the groove or recess formed in the quill extends not only circumferentially on the outside of the quill, but also longitudinally. This allows the locking element to simultaneously serve a holding function, preventing the quill from unintentionally falling out of the quill receptacle during its up-and-down movement. During axial movement, the quill slides up and down within the quill receptacle. Thus, a continuous relative movement occurs between the quill and the quill receptacle during movement or axial movement of the quill. Advantageously, a machining tool, such as a punching tool, is attached to the end of the quill to enable machining of a workpiece, for example, punching openings into it.

[0027] The quill driver and quill are connected by at least one clamping element. It is particularly advantageous if the clamping element can be attached to the quill driver, especially if it can be detachably attached, and engages a portion of the quill in a force-fit and / or form-fit manner. Furthermore, the positioning of the clamping element on the quill driver can be changed depending on the installation angle of the quill slide unit in the tool and the set or adjustable stroke of the quill. In particular, predetermined or fixed attachment points for attaching the clamping element to the quill driver can be provided. By providing at least one clamping element for connecting the quill driver and quill, not only can a simple and easy-to-assemble connection between the quill driver and quill be created, but manufacturing tolerances can also be easily compensated for.This is particularly possible when the clamping element is attached to the quill driver and engages the quill, or especially a groove or recess on its outer surface, in a force-fit and / or form-fit manner. The clamping element thus holds the quill driver and quill together in a force-fit and / or form-fit manner, enabling a joint axial movement of both components. If the quill driver is fixed in a first tool part of a tool, and this first tool part is moved, such as the upper part of a slide unit, then when this upper part, and consequently the quill driver, is moved, not only the quill driver but also the quill is moved up and down simultaneously. The quill moves relative to the quill receptacle within the quill receptacle, since the quill receptacle is advantageously fixed in the second tool part, especially a hold-down device of the slide unit.

[0028] To attach the clamping element to the quill driver, various fastening points can be provided, for example, in the form of a grid screw connection, i.e., by providing a number of adjacent holes into which fastening screws or other fasteners can engage to attach at least one clamping element to the quill driver. The ability to change the position of at least one clamping element on the quill driver thus makes it possible to adjust the positioning of the clamping element on the quill driver depending on the respective installation angle of the quill slide unit in the tool and on the set or adjustable stroke of the quill. As mentioned, the clamping element is attached to the quill driver at different fastening points to allow for this adjustment.

[0029] A further advantage is that the quill driver and the quill holders can be connected to the first and second tool parts at a wide variety of installation angles. This allows not only for approximately vertical and approximately horizontal installation positions, but also for any angular position between a vertical and a horizontal positioning of the quill slide unit and, consequently, of the quill driver and quill holder.

[0030] Furthermore, it is possible to continuously fix the quill driver and quill in a wide variety of positions between the initial and final positions of the quill. This allows for a multitude of installation options for the quill slide unit. At least one device can be provided to fix the quill driver and quill, engaging them and enabling the desired stepless fixing from the initial to the final position of the quill.

[0031] To explain the invention in more detail, an embodiment thereof will be described below with reference to the drawings. These show: Fig. 1 a perspective view of a tool with a first tool part in the form of an upper part and a second tool part in the form of a hold-down with a quill slide unit according to the invention built into it, Fig. 2 a side view of the quill slide unit according to Fig. 1, and Fig. 3 a longitudinal section view along line AA of the quill slide according to Fig. 2

[0032] Fig. Figure 1 shows a perspective view of a tool 1 in the form of a slide unit with a top part 10 and a hold-down device 11. Both are in the Fig. The embodiment shown in Figure 1 is only sketchily represented. The tool 1 serves to punch openings 20 into a workpiece 2. For this purpose, the tool 1 is equipped with a quill slide 3. This extends at an angle to the vertical. This is indicated by the angle α in Fig. 1 indicated, with the vertical line marked with reference numeral 4.

[0033] As seen in the partially cropped view in Fig. The quill slide 3, which can be further removed, is arranged both in the upper part 10 as the first tool part of the tool 1 and in the hold-down 11 as the second tool part of the tool 1. The quill slide 3 is designed as a quill slide unit, as shown in the Fig. 2 and Fig. 3 can be removed more easily. The quill slide unit is pre-assembled as a complete component and is installed as a unit in the tool 1. Part of the quill slide unit 3, namely a quill driver 30, is received and secured in the upper part 10 of the tool 1, and a quill receptacle 31 is received and secured in the hold-down 11. To receive the quill driver 30, the upper part 10 of the tool 1 is provided with a collar-shaped ring 102 projecting beyond its upper surface 100 and its lower surface 101. The quill driver 30 is received in this ring, bearing against a shoulder 103 projecting into the interior of the protruding collar-shaped ring 102. In this area, the quill driver 30 is connected to the upper part 10 and the shoulder 103, respectively, by means of fasteners 32. The fastener 32 can, for example, be a screw inserted into bores 33 or 34.34 of the quill driver 30 in a projecting end section 35 of this or through these bores 33, 34 into corresponding bores in paragraph 103 (in . Fig. (1 not shown) intervene and hold on.

[0034] The quill receptacle 31 is received in a sleeve-shaped section 110 of the hold-down device 11, as is also Fig. 1 can be removed. The quill receptacle 31 is supported in its upper area by a projecting section 36 on a corresponding shoulder 111 of the hold-down device 11, which is also shown in Fig. 1 is indicated. A quill 37 extends through the quill receptacle 31. At one end 38, it is connected to the quill driver 30 via clamping elements 5, 6. At its other, opposite end 39, it is provided on its front side with a machining tool 7, which is Fig. 1 is designed as a stamping tool.

[0035] During the punching or machining process of the workpiece 2 by the tool 1 or the quill slide unit 3, the quill 37 is moved forward and backward in the direction of its longitudinal axis, thus performing a desired number of strokes per unit of time.

[0036] How the Fig. 2 and Fig. To facilitate removal of the clamping elements 5 and 6, they are approximately C-shaped in side view. They have a wider section 50 or 60 and a narrower section 51 or 61. The clamping elements 5 and 6 are connected to the quill driver 30 via fasteners 8, either permanently or detachably, by means of the wider section 50 or 60. The fastener could be, for example, a screw or another detachable fastener. It is also possible to permanently connect the clamping elements 5 and 6 to the quill driver.

[0037] With their respective narrower sections 51 and 61, the two clamping elements 5 and 6 overlap or encircle a projecting section 130 of the quill 37. The narrower sections 51 and 61 of the two clamping elements 5 and 6 engage in a respective groove 131 of the quill 37, the groove 131 being bounded by the projecting section 130 or separating it from the rest of the quill 37. This can, in particular, Fig. 3 can be taken.

[0038] How Fig. As can be seen from section 2, the quill driver 30 has several adjacent bores 40, making it possible to position the clamping elements 5, 6 in different positions on the outside of the quill driver 30. This allows the clamping elements to be attached at several points on the outside of the quill driver in a predefined grid pattern. Depending on the installation angle and the stroke exerted by the quill 37, the clamping elements 5, 6 can be fastened in the appropriate bores 40 using screws or other detachable fasteners. The respective narrower sections 51, 61 of the clamping elements 5, 6 can be continuously positioned along the groove(s) 131. In each case, the respective narrower section 51 or 61 engages the clamping element 5, 6.61 engages in the respective groove 131 and is positively and / or force-fitted to the projecting section 130 of the quill 37, thereby holding the quill driver 30 and quill 37 firmly together. When the quill driver 30 is moved by raising and lowering the upper part 10 of the tool 1, the quill 37 is also moved and can perform the desired upward and downward movement, i.e., the desired stroke, in order to move within the groove 10. Fig. In the execution case shown, openings 20 can be punched into the workpiece 2.

[0039] The quill receptacle 31 is essentially sleeve-shaped and has sliding surfaces or sliding elements 41, 42 on its inner side. The sliding elements 41, 42 serve to guide the quill 37 during its upward and downward movement relative to the quill receptacle 31. To prevent twisting or rotation of the quill 37 within the quill receptacle 31, a locking element 9 is provided in a recess 43 of the quill receptacle 31. The locking element 9 also extends into the interior of the quill receptacle 31 to the outer side of the quill 37. This is particularly important Fig. 3. The quill 37 has a recess or longitudinal groove 132 in this area. The locking element 9 engages in this longitudinal groove 132. Since the locking element 9 engages positively in the longitudinal groove 132 of the quill 37 in the area of ​​contact and is also positively arranged or mounted in the recess 43 of the quill receptacle 31, twisting, i.e., unintentional rotation, of the quill 37 moving relative to the quill receptacle 31 can be effectively prevented.

[0040] What next? Fig.As can be seen from section 3, the longitudinal groove 132 does not extend continuously from one end of the quill 37 to its opposite end, but is limited in the longitudinal direction by the wall sections 133, 134 that define the ends of the longitudinal groove 132. This limitation of the longitudinal groove 132 by the wall sections 133, 134, in conjunction with the locking element 9, prevents the quill 37 from unintentionally falling out of the quill receptacle 31. This is achieved in particular by the wall section 133 in conjunction with the locking element 9.

[0041] The provision of the compact quill slide unit 3 with quill driver 30, quill receptacle 31, quill 37, and clamping elements 5, 6 connecting the quill driver and quill allows for quick and easy installation and removal of the quill slide unit 3 from the upper part 10 and the hold-down 11 of the tool 1. Furthermore, the quill driver 30 and quill 37 can be continuously fixed from the initial position to the final position of the quill 37, i.e., the starting and ending working positions of the moving quill 37. This enables a wide variety of installation options for the quill driver 30 and quill 37, or indeed for the entire quill slide unit 3.

[0042] In addition to the quill slide variants described above and shown in the exemplary embodiments, which are designed as quill slide units, numerous other configurations are possible. In these, the quill, quill driver, and quill receptacle are connected by these connecting elements to form a compact unit, which can then be installed in and removed from a tool. The quill slide unit can thus be used in a wide variety of tools, not only in stamping tools as described above, but in any other tool where a quill is required.
