Definitions
- the invention relates to a lower tool for a bending machine, in particular Gesenkbie- machine, comprising at least one Reibredu Vietnamese silicates to reduce the friction between the bottom of the lower tool and a tool holder.
- the forming or bending tools are optimally aligned to tool holders of the bending machine for the respective forming operation and can optionally be clamped or clamped against unintentional displacement during the bending process.
- wel che allow a smooth exchange especially in sub-tools.
- Under tools generally have an elongated body, which has on its upper side designed for the respective forming operation Gesenkform.
- a derar term lower tool has on its underside usually on a tool shank, wel holes used for receiving in a guide groove of a tool holder.
- Object of the present invention was to overcomes the disadvantages of the prior art and len a lower tool with a Reibredu Vietnamese silicate available to set, by means of which a user is able to make a tool change relatively simple, inexpensive, safe and fast.
- the device according to the invention relates to a lower tool for a bending machine, in particular special die bending machine, which comprises a longitudinally extended base body and at least one therein received or formed Reibredu Vietnamesesvorraum.
- the main body has on its underside a tool shank and can in the transverse direction distrschultem, which are arranged set back relative to the tool shank have.
- the at least one Reibredu Vietnamese dissemiconductor is on the underside of the Grundkör pers to reduce frictional force between the underside and the tool holder during a displacement of the sub-train in the longitudinal direction designed such that a Ge gravity of the lower tool on the tool holder under application of a pre-tension in the direction of gravity a relative the weight force resulting lower resulting normal force of the lower tool on the tool holder causes.
- the present invention is based on the finding that a reduction of the wear of the lower tool and / or the tool holder does not necessarily have to take place in complete detachment of the lower tool or the tool holder from the tool holder.
- a Ver push force is referred to as the force which is required for displacement of the lower tool on or within the tool holder in the longitudinal direction.
- the amount of frictional force normally acts in the opposite direction of the direction of displacement. For a displacement of the tool, the displacement force must be greater than the frictional force.
- the at least one Reibredu Vietnamese dissemiconductors device is arranged in a, preferably in each case provided for receiving space of the lower tool of the art, that the Reibredu Vietnamese dissemiconductors device relative to the adjacent or surrounding bottom at least in one direction, preferably in the direction of Weight force, is designed to be movable. It is possible for each Reibredu Vietnamese dissemiconductor provide a separate receiving space in the lower tool or to arrange several Reibredu Vietnamese dissvorraumen in a common receiving space.
- the receiving space can be designed, for example, as a milling pocket within the lower tool in such a way that a complete reception of the Reibredu Vietnamese Vietnamese diss, in particular a sliding element, sliding wedge or a Rohe, is possible.
- the extension of the receiving space in the longitudinal direction of the substation can be selected in such a way that an at least partial displacement or movement of the Reibredu Vietnamese direction within the receiving space is possible depending on the execution of the Reibredu Vietnamese.
- the positioning of the receiving space in the tool shank of the lower tool and / or in the tool shank of the Un terwerkmaschines a formation of the Reibredu Vietnamese device can be avoided as a disturbing contour in the case of tool clamping. Thus, a good application of force tool clamping can be guaranteed on the lower tool.
- the use of an automated change system for example by means of a robot, is facilitated.
- the Reibredu Vietnamese distals device comprises an adjustable Federele element for adjusting the height of the biasing force.
- the adjustable spring element can be formed, for example, as a leaf spring, plate spring, screw benfeder or as a resilient plastic body or the like. It has proved to be advantageous that one side of the spring element is supported on the lower tool and clamps a sliding element, a sliding wedge and / or a tube in the direction of the weighting force of the lower tool or in the direction of loading with a predefinable spring force. It may be advantageous in certain threads, if the maximum spring force of the spring element is greater than the weight of the lower tool. In this case, he has to measure the expert in accordance with the present geometric conditions to achieve an opti male interpretation of the adjustability of the spring element.
- the spring force can be determined very easily via an externally adjustable Auflagerein.
- the adjustability of, for example, a coil spring can be changed by a rotary device for adjusting the spring force.
- the ability to adjust the amount of biasing force allows the skilled person to realize faster set-up speeds, as well as to significantly reduce damage to the lower tool or the tool holder.
- Another advantage is that several Reibredutations devices can have different biasing forces, which can be specifically taken into account the geometric conditions of the lower tool and the distribution of the weight.
- the biasing force is at least 20% of the weight of the lower tool.
- the wear sensor can be designed as an optical and / or mechanical sensor and should have the most direct visual or contact connection to the sliding element, the sliding wedge, the roller, and / or their optional covering.
- the wear sensor allows detection of the remaining available covering and / or the strength, which are made detectable for example by suitable markings for the sensor. It can be avoided in this way any damage to the lower tool and / or the tool holder by timely replacement of the sliding element, wedge, the roller and / or the covering become. This increases safety and allows defined working or maintenance intervals.
- connected to the wear sensor wireless transmission device for transmitting the wear data to the Anlagensteu tion is formed in the lower tool and / or the tool holder.
- a fixing agent here e.g. relatively simple running screws for fixing the sliding element or a sliding wedge in the Reibredu Vietnamesesvorraum be used.
- clamping or locking elements such as an openable flap with a passage for example, a roller or a sliding wedge on the bottom are conceivable.
- the fi xierstoff can be designed to permit at least partial movement of the Gleitele element, wedge or role in the loading and / or catching direction.
- the at least one Reibredu Vietnamese distalgestingsvorraum is aligned in the loading direction aligned and / or in the transverse direction on both sides of the lower tool is.
- the service life of the Reibredudictions device can be extended and prevent excessive wear of a sliding element.
- the Reibredu Vietnamese, Vietnamese, растение has a, preferably elastic, coating in at least loading direction for contacting the Malawibergernah meober Design.
- the use of such a coating allows a specific coordination of required strength and / or frictional properties, such as a defined coefficient of friction m.
- the appropriate choice of the pad and its pad thickness can serve to optimize the elastic properties with respect to the effect of the biasing force.
- the coating may e.g. be designed as a resilient material, such as rubber, and possibly at the same time develop an effect as previously mentioned spring element. This can bring particular advantages when the sliding element of the Reibredu Vietnamese Device is designed as a role.
- such a coating when needed or reaching a minimum strength can be relatively easily replaced, which in turn brings significant cost and time advantages.
- plastics such as PTFE, PEEK and the like.
- the Reibredu Vietnamese spatula is designed as a sliding element, wherein the coefficient of friction of the sliding element relative to the Tool holder has a lower coefficient of friction m2 than the coefficient of friction of the lower tool relative to the tool holder m ⁇ .
- Such a sliding member and the application of the biasing force he allows a transfer of a large part of the weight of the lower tool over, for example, a low-friction surface of the sliding member.
- the frictional force in a displacement in the longitudinal direction can be significantly reduced.
- damage to the lower tool and / or the tool holder can be effectively avoided, since the wear in the friction is at least partially, preferably completely, carried by the sliding member.
- the condition mi> m 2 has proven to be particularly advantageous.
- Such Gleitele elements may have a flat, but also curved, bearing surface in the direction horrauf acquisition.
- the sliding element may have a covering on the underside in the direction of the work tool receiving, or else be formed in one piece.
- the sliding element is made of a metal be and is provided on the sliding surface with a coating which for the desired frictional properties, in particular the coefficient of friction m 2 , provides.
- a sliding element can be designed to be movable in part within the receiving space, partially along the longitudinal direction, and in a particular embodiment also as a sliding wedge.
- the sliding element and / or the lining of the sliding element has bevelled and / or rounded edges.
- This measure can significantly reduce the risk of jamming during displacement of the lower tool and contributes to a protection of the lower tool and the tool holder.
- the coefficient of friction of the sliding wedge relative to the wedging planes should have a clotting Geren friction coefficient than the coefficient of friction of the sliding wedge against the mea- tion m 2 .
- the operation of such a sliding wedge substantially corresponds to the previously described sliding element.
- the biasing force can be applied analogously to the sliding element on the sliding wedge, whereby a significant proportion of the weight can be transmitted from the at least one sliding wedge on the tool holder.
- the condition mi> m 2 > p 3 has proven to be particularly advantageous since, in the limiting case, the lower tool is guided flat upwards along the wedge during displacement in the longitudinal direction and may even lose contact with the tool holder. In this way, a direct contact of the lower tool to the tool holder can be passed. The damage to the lower tool and / or the tool holder is thereby avoided that a relatively cheap and easily replaceable sliding wedge or lining of the sliding wedge carries the wear.
- a roller axis ent long the wedging planes is designed to be movable and limited the receiving space in the longitudinal direction by a stop and the coefficient of friction of the roller axis with respect to the wedging planes has a lower coefficient of friction m 4 than the coefficient of friction of the roller relative to the tool holder m 2 and the coefficient of friction of the roller opposite the tool acceptance is m 2 higher than the coefficient of friction of the lower tool relative to the Malawiauf exception mi.
- the locally higher surface pressure of the roller relative to the lower tool due to the smaller ren support cross-section allows a consistently good contact of the Reibredu Vietnamesesvorrich- device for tool holder. It is analogous to the above-described idea of the sliding wedge and / or the sliding element that the biasing force of the friction reduction device results in that the weight of the lower tool is at least partially transmitted from the roller to the tool holder. It has surprisingly been found that a spring-elastic coating of the role, which can make up a proportion of about 10 to about 80% of the radius of the roll, can exert an effect as a spring element. The spring-elastic guided roller can thus apply the required biasing force and remains static, ie stationary state by the weight in the middle of the receiving space. An unintentional displacement of the lower tool is therefore excluded.
- the receiving space is in the loading direction of the tool holder pioneering in the longitudinal direction designed such that a rest position of the roller or roller axis is seen easily.
- the receiving space is dimensioned sufficiently large di that a deflection of the roller along the longitudinal direction can take place.
- the choice of friction conditions with a ratio of m 2 >mi> m 4 can cause the roller to always return to the rest position in the static case.
- suitable choice of material and / or friction coefficients and / or elastic properties of the roll or the loading lags can be achieved that in a displacement of the lower die in the longitudinal direction, a slipping of the lower die on the roll.
- the weight of the lower tool is thus transmitted via the roller axes at least partially on the role.
- the rollers can contribute to facilitated displacement in the longitudinal direction by the comparatively low rolling resistance.
- in the longitudinal direction of the stop of the receiving space is also formed as a role to prevent jamming of the roller or roller axis. Due to the oblique or oblique position of the wedging planes in the longitudinal direction relative to the bottom or the tool receiving surface, it may even come to a complete relief of Kon contact areas of the lower tool, whereby the reduction of the resulting Nor malkraft of the lower tool on the tool train recording is done, so to speak complete.
- the water case may occur when the lower tool is supported along the inclined wedging planes when displaced in the longitudinal direction on the roller axes and thereby a lifting of the lower tool is achieved in the limiting case.
- Upon reaching the desired position in the longitudinal direction by means of the tool holder can by the very low friction forces and the low coefficient of friction m 4 of the roller axis against the wedging planes a kind of self-centering the Reibredu Vietnamesesvorraum done. This also contributes to the elastic trained the role or the lining, which cause corresponding restoring forces.
- the roller axle can be secured against falling out from below by means of a fixing means, which can be eg a flap or a rail. In the manner described can be used ver very advantageous and easy a movable in the loading and / or longitudinal direction roller to adjust the biasing force and to avoid damage to the lower tool and / or the tool holder.
- the skilled person is responsible for selecting the angle of the wedging planes.
- the wedging planes can be executed as straight, continuously rising surfaces, also as a kind of circular segment, in order to simplify the self-centering of the sliding wedge or the roller.
