Description

The invention relates to a tool slide.

Tool slides, which are also called wedge drives, are known.

Wedge drives are used in tools in metalworking, e.g. used in forming presses. Associated with these wedge drives are usually facilities or tools that allow punching or otherwise deforming. A conventional wedge drive has an upper guide part comprising a slider element and a slider guide element and a lower guide part comprising a driver element and vice versa. The wedge drives are moved by the slider guide element by a drive applying a generally vertical pressing force. On the part of the driver element wedge drives are mounted in the tool or the press on a base plate on which the workpiece to be machined is placed directly or via a corresponding support device.

From the DE 26 40 318 B2 is known a wedge drive for redirecting a vertical pressing force in an angularly acting force for the forming process. This wedge drive consists of a drive wedge, on which acts a vertical force of a corresponding work press, and a slide wedge, which transmits the force in the horizontal. The driver wedge and the slide wedge run either over a rounded cooperating region or, in another embodiment, over a roller.

From the DE 24 39 217 A1 a wedge press with a prism-shaped wedge guide is known, wherein the contact surfaces are roof-shaped or channel-like and with the roof or gutter extending over the entire pressure-receiving width of the wedge.

From the DE 23 29 324 B2 is a wedge press with a device for preventing unwanted movements of the wedge with a prism-shaped wedge guide known.

Usually, overhead wedge drives used in the body industry consist of a driver, a slider, and a slider receiver. On the top of the slider recording acts a vertical force that pushes the slider recording down. The driver is firmly anchored in the tool, so that when pressing on the slide holder, the slide anchored in the slide holder is pushed in any direction outside the vertical working direction.

Frequently, overhead wedge drives are used. In this design, the slider depends in his leadership movable in the slide holder. The driver sits rigidly in the lower part and specifies the working direction of the slider. During the downward stroke of the press, the spring-loaded slider sets on the driver and is pushed by the continuing slide holder over the driver surface in the working direction.

The known from this prior art wedge drives have disadvantages, so that the slide used often have short lives and are exposed due to their structural design high wear. Therefore, they often need to be replaced after a short period of time because they show signs of wear, so that an exact Redirecting the vertical pressing forces is no longer possible, which leads to unacceptable tolerances in metalworking.

From the DE 197 53 549 C2 is known a wedge drive, which is produced in a continuous industrial production process and should have long service lives. For the guidance of the slide in the slide holder angle brackets are present, which are formed of bronze and have attached in the angle bar sliding elements made of graphite. In general, this wedge drive for deflecting a vertical pressing force with a driver, a slider and a slider receiving equipped, the driver has a prismatic guide and the travel of the slider on the driver is shorter than the travel of the slider on the slider recording and the ratio of the paths to each other is at least 1 to 1.5 and the angle α between the traverse paths is 50 ° to 70 °. In such a slider, the driver element has a prismatic surface, wherein the flanks of the prismatic surface are formed sloping outwardly. In addition, this wedge drive has forced return brackets on two opposite sides in respective grooves of the slider element and the driver element. In this way, in the case of a breakage of the slider element in its starting position retrieving spring element ensures a return of the slider element at spring break and thereby to avoid tearing out of screwed punching elements. The slider element is attached to the slider guide member via the angle brackets and retaining screws and can be moved along the angle strips relative to the slider guide element.

From the US 5,101,705 A Another wedge drive is known in which the slider element hangs on angle strips or means which is attached to the slider guide element. In this case, it is necessary that the adjacent plates or elements required for fastening be precisely ground in order to guarantee the running clearance required between slide element and slider guide element. In this wedge drive as well as in the other known wedge drives, in which slide guide element and slide element are interconnected via angle strips and screws, is disadvantageous that all tensile forces are introduced into the screws, which in particular at the moment by an extension of the screws or takes place of the surrounding material, the running clearance of the mutually moving slider guide elements and slide elements is impaired. This subsequently leads to a poorer stability, since the wear is particularly increased due to the bracing of the tool in this area. In addition, it proves to be disadvantageous that the slider element can not extend laterally when heated, since it is narrowed by the angle strips in this regard. This can also lead to increased wear of the tool.

From the EP 1 197 319 A1 a wedge drive is known in which the slider element and the slider guide element are held together by means of guide clips. As a result, it should not be necessary to exactly grind additional angle strips or other devices connecting these two elements in order to guarantee a required running clearance. In addition, the running clearance is not affected even when heating the wedge drive or the tool, since not only manufacturing tolerances, but also occurring expansions of the material can be absorbed by the connection via a guide bracket. The stability of the wedge drive is therefore no longer impaired or shortened. Despite the omission of a grinding can be a high running accuracy be achieved. The guide brackets engage in this form-fitting manner in the slider guide element, whereby the slide member depends on the guide guide elements on the slide guide element via this positive engagement. As a result, it is not necessary to provide a grip on the slider guide element via screws, which are on the one hand wear-prone and on the other hand can cause an already mentioned impairment of the running clearance when heated.

From the DE 10 2007 045 703 A1 is known a wedge drive with slide holder, wherein between the slider element and the slider element receiving a dovetail-like or prism guide means is provided. In this document it is stated that the approximately vertical approach of a press tool, which is referred to as a working stroke, which is located in its rearward position slider element touches the rigidly positioned driver element and is supported by this supported on its pointing in the direction of skew. The movable sliding element is thus driven only driven by the press tool and controlled forward or outward to perform the punching or forming work can. In the rear stroke, in which the press tool has exceeded its lower suction point and its two parts move apart again, usually the movable slide member is pushed back by means of a suitably designed resilient element to its original position, after which the process can be restarted. It is stated that the retraction force required for retrieving the slider element is usually between 2% and 10% of the actual working force and the weight of the slider element. For the size of the pressing force here are the dimensions of the pressure-transmitting surfaces referred to as sliding surfaces be determining the respective inclinations of linear guides in the slider element receiving and tilting of the driver element and the interaction of the surfaces and inclinations and the structure of the slider element itself. The pressures to be transmitted are usually between <100 kN up to several 10,000 kN.

Furthermore, it is stated that the linear guide in the slide element holder is intended to guide the movable slide element without play and in the process must endure high press forces and realize long service life. As a tolerance of the running accuracy of the movable slide element, a tolerance of 0.02 mm is specified.

As already stated in the prior art, such wedge drives or slides consist of a slide assembly, which in turn consists of a driver, a slide part and a slide bed. In this case, the slide part is fastened with retaining elements on the slide bed, wherein the slide part between the driver and slide bed is slidably suspended. Corresponding bevels on slide bed and driver are arranged inclined in opposite directions, so that the slide member "pushed out" when moving together slide valve and driver between the two parts. Since, as already stated, in this case act very large forces, a corresponding guide must be provided.

The known guides here are the cover strip guide, the guide with guide clips, the guide with guide columns and the dovetail guide ( DE 10 2007 045 703 A1 ).

The majority of these guides are attached to the outer surface of the slider. It must be noted that the power transmission and the leadership are not optimal.

On the one hand, the main slide guide on the sliding surfaces must be carried out thereby offset inwards, so that less power transmission is possible. In addition, often results in a high space requirement and it could be found deformations by initiating operating forces (work and withdrawal forces).

In the known dovetail guide has the disadvantage that this relatively often the game must be reworked, which means that the slide must be completely uninstalled. Even with all other sliders, the assembly and disassembly is very complex and expensive. On the one hand, this can only be carried out to the rear in the entire slider body, with large masses having to be moved in close alignment with the aid of a crane, especially in the case of large sliders, due to the high weight of the slider body and the greatly limited installation space. In the case of clip-type slides, lateral installation space must be provided for assembly and disassembly, so that an optimized position of the slides is not guaranteed for certain applications.

From the DE 10 2012 014 546 A1 a wedge drive is known, wherein the wedge drive is to have a sliding element holder, a movable slide carriage and a driver and is formed with sliding surfaces between the slide carriage and the driver element, wherein at least one sliding surface a clamping device should be present, the pressing force adjustable during assembly of the Working tool simulated to produce a backlash between the at least one slide carriage and the at least one slider receptacle. According to this document, a high tolerance accuracy is to be achieved, namely when mounted in the tool slide upper part comprising the slide carriage and the slider element recording on the one hand and the driver on-03292PWOEP dererseits, this being achieved in that when the working tool is mounted on the slide, ie when the working tool, such as a punch, is attached to the slider, the slides are held together with the simulated pressing force.

From the WO2009 / 039895 A1 a tool slide according to the preamble of claim 1 is known. The object of the invention is to provide a slider guide, which has optimized space and power transmission properties with improved assembly capability.

The object is achieved with a tool slide with the features of claim 1.

Advantageous developments are characterized in the subclaims.

According to the slider guide between slider body and slide bed is designed as a prismatic guide or flat guide, wherein also a guide bar with prismatic or dovetailed cross-section is mounted in a groove with a corresponding cross-section and the web overlapping sliding elements of the respective other corresponding slide member. In addition to the prism-shaped or dovetail-shaped embodiment, the guide play is adjustable according to the invention by the interaction of at least two oblique surfaces between a sliding element and the slide bed which supports this. For this purpose, a separate sliding element can also be provided.

Specifically, this guide is applied to a known slider assembly consisting of driver, slider member and slider bed, the slider member being slidably supported in the slider bed. Between the driver and the slide part sliding pairings are arranged.

In an advantageous development, the setting of the guide clearance by means of a separate component is at least secured, possibly also made. This member is mechanically applied in a direction of adjustment to the sliding member and / or the sliding members having the inclined surface or the inclined surfaces. In this case, on the one hand, the component may represent a distance between a fixed part of the slider body and / or slider bed, on the one hand, and the adjustable sliding surface, specified for the adjustment made.

In addition, according to the invention, the component itself may be wedge-shaped or wedge-shaped with a bevel, which cooperates with a corresponding inclined surface of the sliding surface to be adjusted, the sliding surface displaced. In this case, an actuating means is provided for the component, with which the component in a simple manner from the outside, the sliding surface actuated, can be adjusted. This is in particular an adjusting screw, with which the component, this moving, can be acted upon relative to the sliding surface.

The sliding element is wedge-shaped with a bevel. This bevel is in this case formed on the groove-side short surface of an L-shaped sliding element, wherein the groove with a corresponding wedge-like surface, in particular a corresponding oblique surface is formed.

Here, both sliding elements or only one sliding element may have the slope. By moving the sliding element along the direction of the slope (usually in the longitudinal direction of the elongated sliding strips), the guide clearance between the slide bed and the slider body is changed.

The L-shaped sliding element may in this case also be formed of individual sliding elements, which are L-shaped relative to one another, but this increases the assembly effort.

In particular, in the case in which both sliding elements have the slope, an adjustment of the slide bed to the slider body can be achieved by oppositely moving the sliding strips or sliding elements.

The invention relates to a tool slide, in particular wedge drive, at least comprising a slide bed and a slide part, wherein the slide part is slidably disposed on the slide bed with a prism guide and a groove and a protruding into the groove web are provided, wherein between the web and the groove at least one Sliding element is provided, wherein a detachable from the slide part driver is present and between the slide part and the driver in the attached state also a prismatic guide consists of inclined elements of the slider body and corresponding inclined surfaces of the driver, wherein between the slide bed and the slider body a prism guide or flat guide such is formed, that sliding elements of the slider bed and corresponding sliding elements of the slider body are arranged with respect to an x-axis inclined at a prism guide or perpendicular to a flat guide, wherein the Slide member towards the groove has a wedge-like, tapered surface, with which it rests on a corresponding surface of the groove wall and the corresponding groove wall has a corresponding wedge-like chamfer, so that an axial displacement of the sliding element according to a longitudinal axis direction reduces a gap between the web and sliding member or increased.

The invention further relates to a tool slide, wherein the sliding elements are L-shaped sliding strips or sliding plates, which have the groove center facing surfaces with which they define a space between them and the slider body towards sliding surfaces are formed, being symmetrical to the vertical axis of the Guide member or the guide web upwardly into the groove extends, wherein the guide web has elongated surfaces, with which it is formed adjacent to the surfaces of the L-shaped slide strips.

In addition, the invention relates to a tool slide, wherein the guide body is formed as an elongated rail or web-like component, wherein the web is prismatic or dovetail widening in the projecting into the groove portion, wherein a guide prism or a dovetail guide is formed, which in the groove superimposed, wherein the web is mounted with prismatic surfaces on corresponding surfaces of the sliding strips in the groove.

The invention also relates to a tool slide, wherein a fitting piece is present, which is inserted between a wall of the slide bed and a wall of the sliding element and holds a defined position of the sliding element.

Furthermore, the invention relates to a tool slide, wherein the fitting piece is arranged with a screw on the slide bed or the sliding member.

In addition, the invention relates to a tool slide, wherein the fitting piece has at least one wedge-shaped inclined surface which corresponds with an inclined surface of the slide bed or an inclined surface of the sliding element as a wedge drive for displacing the sliding element.

The invention also relates to a tool slide, in which the fitting has wedge-like inclined surfaces which correspond both to an inclined surface of the slide bed and with an inclined surface of the sliding element as a wedge drive for moving the sliding member.

Furthermore, the invention relates to a tool slide, wherein arranged for adjusting the guide clearance, the fitting piece between an edge or surface of the axially located in front of or behind the slide strip slide bed. This edge or surface is spaced from an end face of the sliding strip.

The invention further relates to a tool slide, wherein the fitting piece to hold it in place, with a fixing part the edge or surface of the slide bed over protrudes, especially in the region of a heel formed for this purpose and is fixed there by means of a screw, both passes through the fitting and now the material of the slide bed is screwed, whereby the axial distance between the edge and the edge is fixed.

In one embodiment of the invention, the fitting piece is arranged between the edges, wherein the fitting piece is movably arranged between the edges and the overhanging region and the step are spaced, so that by screwing the screw, the fitting piece is arranged in the area between the edges pressed into, wherein the Gleitleistenseitige edge or surface of the fitting is provided with a bevel such that the fitting is formed widening and / or the edge of the slide strip is provided with a corresponding slope such that when you push the fitting into the area between the edges of the slide bar is moved, whereby the guide play is reduced.

An inventive tool slide 1 has a slide bed 2, a slider body 3 and a driver. 4

The slide part 3 is arranged hanging on the slide bed 2 in the case shown, wherein the slide part 3 can be lifted by the driver 4. The driver 4 is usually arranged in a first (in the case shown the lower) mold half, while the slide part 3 via the slide bed 2 at a corresponding second (upper) mold half (not shown) is arranged.

The slide bed 2 is approximately box-shaped and has an elongated rectangular groove 5, wherein in addition to the elongated rectangular groove 5 screw holes 6 for receiving corresponding screws (not shown) are provided. The groove 5 and the adjacent, the groove defining surfaces 7 form a bearing surface for L-shaped slide strips 8, which rest on the surfaces 7 and hineinerstrecken with an L-leg 9 in the groove 5.

The L-shaped wear strips 8 have mounting holes 10 for screwing mounting screws for placement in the screw holes 6. The L-shaped wear strips 8 have the Nutmitte facing diverging surfaces 11, with which they define a prismatic space between them.

To the groove 5 laterally delimiting walls 19 toward and adjacent to these L-legs 9 have sliding surfaces 22. The surfaces 22 extend relative to the thickness of the L-leg 9 between the Nutseitenwandung 19 along the longitudinal extent of the L-shaped wear strips 8 obliquely so that the L-legs 9 are wedge-shaped or wedge-shaped. This bevel or wedge shape runs at an angle of 1 ° to 5 °. The Nutseitenwandungen 19 are formed in a corresponding manner with respect to the longitudinal extent bevel, so that a displacement of the slide strips 8 according to the longitudinal direction, the surfaces 11 moves more or less towards Nutmitte.

Towards the slider body 3, the L-shaped slide strips have sliding surfaces 12, which are planar and perpendicular to an X-axis 13 shown.

The slider body 3 has sliding surfaces or sliding strips 14 which correspond to the surfaces 12 and are designed as sliding partners to the L-shaped slide strips 8.

Symmetrically to the vertical axis extends between the sliding strips 14, a guide web 15, which is designed in particular as a guide prism or dovetail, up into the groove 5 in. The guide prism 15 has elongated prismatic surfaces 16, with which it rests against the surfaces 11 of the L-shaped slide strips 8.

Facing the driver, the slider body 3 has further slide strips 17, which are arranged obliquely with respect to the X-axis 13 and correspond with prismatic guide surfaces 18 of the driver 4. The strips 17 form, as they are connected to the slider body, lift-off sliding strips, which are brought along when moving together of the upper tool part and the lower tool part in operative connection with the surfaces 18.

Since the guide surfaces of the L-shaped slide strips 8 and the corresponding surfaces 12 of the strips 14 are arranged vertically with respect to the X-axis 13 and are also arranged perpendicular to the guide prism 15, one speaks in this embodiment of a so-called flat guide.

The obliquely corresponding sliding elements 17, 18 between the slider body and driver form a so-called prism guide.

In a further advantageous embodiment ( Fig. 2 , like parts are provided with the same reference numerals), the tool slide 1 also consists of a slide bed 2 and a slider body 3 (the driver 4 is not shown).

The slide part 3 is arranged hanging on the slide bed 2 in the case shown, wherein the slide part 3 can be lifted by the driver 4. The slide bed 2 is approximately box-shaped and has an elongated groove 5. The Nutseitenwandungen 19 extending from the groove bottom, converge and thus form a dovetail groove. The groove 5 bounding surfaces 7 converge with each other. On the surfaces 7 are L-shaped sliding strips 8, which extend with a narrow, short L-leg 9 into the groove. The L-shaped sliding strips have to the surfaces 7 towards contact surfaces 11 and the slider body 3 toward sliding surfaces 12, which are planar and obliquely divergent with respect to a vertical axis. These surfaces 12 slide on corresponding sliding surfaces 14 of the slider body. 3

The sliding surfaces 14 of the slider body 3 are accordingly formed roof-shaped inclined, with respect to the vertical axis centrally centrally symmetrically arranged the guide bar 15 or dovetailed part of the guide web 15 of the slider body is located on the short L-shaped legs 9 of the slide strips 8 prismatic Surfaces 16 are formed adjacent. The surfaces 16 and 14 close the approximately the same angle as the surfaces 9, 12 and are in the example shown approximately perpendicular to each other.

Since an exact fit and guidance of the tool slide, in particular between the slide bed and the slider body is necessary, the leadership of the slider body in the slide bed must be adjustable or the slide strips 8 and the prism 15 must be adjusted to each other.

For this purpose are ( Fig. 3 to 6 ), the mounting holes 10 in the wear strips 8 as elongated holes so that they are along the mounting screws 20 and thus along an adjustment direction 21 slidably.

The displacement of the slide strips 8 along the direction 21 does not change any existing gaps or gaps between the surfaces of the slide strips 8 and the L-leg 9 and the guide prism 15. Relative to the longitudinal extension and the directions 21, therefore, run the contact surfaces 22nd the L-leg 9 of the L-shaped slide strips analogous to the first embodiment 8 wedge-like or wedge-shaped. This means that they change their thickness relative to the longitudinal extent. The slope has, for example, a slope of 1-5 degrees.

The oblique contact surfaces 22 on the L-legs 9 of the L-shaped sliding strips 8 are directed to corresponding corresponding surfaces 19 of the groove 5.

A displacement along the direction 21 thus causes, due to the inclined surfaces 22, 19, the distance between the surfaces 11 of the L-leg 9 and the surfaces 16 of the guide web 15 or guide prism 15 is reduced or eliminated. In this case, both both slide strips 8 and only one slide bar 8 can be moved.

Since this at the same time on an approximation of the wear strips or removal of the wear strips in the transverse direction, ie the direction 23, causes, however, the slots 10 would have to be designed so that a floating mounting is also possible in the direction 23 around the screws 20 around.

In order to adapt the slide strips 8 to the guide prism 15 and thus also to adapt the exact position of the slider body in the slide bed, for example, from a stop position of the screws 20 in the slots 10 (FIGS. Fig. 5 ) the setting can be made.

To set an appropriate setting of the leadership game from the outside ( Fig. 10 . 11 ), a fitting 40 is provided according to the invention. The fitting 40 is disposed between an edge or surface 41 of the axially located in front of or behind the slide strip 8 slide bed 2 and this edge or surface 41 spaced from an end face 42 of the slide bar 8. In order to hold the fitting 40 in place, the fitting overhangs the edge or surface 41 to the slide bed 2 with a fixing part 43, in particular in the region of a heel 44 formed for this purpose, and is there fixed by means of a screw 45, both the fitting 40 passes through and is screwed into the material of the slide bed 2. The axial distance between the edge 41 and the edge 42 can thus be determined, so that the position of the screws 20 is fixed within the slots 10. To set different distances depending on the setting position between the screws 20 and the slots 10, the fittings between the edges 41, 42 may have different widths.

This means that after adjusting and fixing the slide bar 8 via the screws 20, which rest in the slots 10, to secure this setting, a matching fitting 40 is used.

In a further advantageous embodiment of the invention ( Fig. 12 ), the fitting piece is also disposed between the edges 41, 42, but is movably arranged between the edges 41, 42 in that the overhanging portion 43 and the Level 44 are spaced apart from each other so that by screwing in the screw 55, the fitting 40 seen from the outside can be pushed deeper into the area between the edges 41, 42. In addition, the sliding strip-side edge or surface 46 of the fitting 40 is provided with a bevel such that the fitting 40 widens outwardly. The edge 42 of the sliding strip 8 is provided with a corresponding slope such that when pushing in the fitting 40 in the area between the edges 41, 42, the slide bar 8 is moved in the direction of the arrow 47. Preferably, the direction 47 is also the direction with which the guide play is reduced. As a result, by screwing the screw 45 in the slide bed 2, the fitting 40 are screwed into the area between the edges 41, 42 and thus the slide bar 8 are moved accordingly in one direction to less guide play. The advantage here is that by screwing the fitting piece from the outside, which is relatively easy to accomplish, the adjustment or adjustment of the guide clearance is easily possible.

Of course, it is also possible to form the slider bed facing edge 48 of the fitting 40 with the corresponding slope and accordingly the edge 41 on the slide bed with a corresponding slope, which acts in the same way as the first embodiment form.

In particular, in an oblique installation of the sliding strips 8, the screws 45 are reset from the outside against damage behind the outer surface of the slide bed 2 and still achieve good, especially with an angle key or the like tools.

In a further advantageous embodiment ( Fig. 7 to 10 ) follows the adjustment in another way. In this embodiment If necessary, the surfaces 19 of the groove 5 and the slider bed 2 and / or the surface 22, which faces the wall 19, formed with a slope.Wenn both surfaces 19, 22 are formed obliquely, the formation of the slopes is such that it is in the same direction, ie the surfaces diverge from one another or converge and define a wedge-shaped gap between them.

In order to adjust the distance between the sliding surface 11 and a mounted between the sliding surfaces 11 prism 15 with sliding surfaces 16, a corresponding wedge-shaped fitting is used in this embodiment, which either an inclined surface 64 to the wall 22 or an inclined surface 65 depending on the design Wall 19 out or two inclined surfaces 64, 65 to sloping walls 19, 22 out has. Accordingly, this wedge bears against these walls 19, 22 and extends between the sliding strip 8 and the groove 5.

If this wedge 60 is moved in or out in accordance with a direction of movement 61 in the gap between the surfaces 19, 22, the slide bar 8 is moved either entirely in the direction of a groove center 62 or in each case moves the directions 23 away from it.

In order to move the wedge-shaped fitting piece or the wedge 60 into and out of the gap, the wedge 60 has an offset 63, which is arranged on the wedge such that the free end of the cap 63 is in the region of the material of Slider and here in particular in the area of the slide bed 2 is located. The cranked portion 63 is penetrated by a screw 66 which is rotatably mounted in the bend 63. This screw 66 acts with its screw head or with a corresponding device the cranked region 63, so that screwing the screw 66 into the slide bed 2 (FIG. Fig. 8 ) moves the wedge into the gap between the surfaces 19, 22 and unscrewing the screw moves the wedge 60 out again.

In a further embodiment, the screw 66 is not screwed into the slide, in particular in the slide bed 2, but directly in the sliding plates 8, which ultimately leads to the same result when screwing in and out.

In the invention it is advantageous that a simple, but very reliable and robust adjustment with good accessibility is achieved even in very tight installation situations by the externally adjustable and sliding wear strips, not adjusting the entire slide must be dismantled, but adjusting the fitting pieces with the appropriate screws sufficient for this.
In the invention it is also advantageous that a very compact, but also very stable guidance of the slider body 3 in the slide bed 2 is achieved by the adjustable wear strips and their L-shaped form on the one hand and the prismatic guide prism 15 on the other side and also in a simple The smallest tolerances are adjustable.
