Definitions

  • the invention relates to tweezers which have two legs in a manner known per se, each of which is connected to one another at one of its ends and can be brought together for temporary engagement by the action of a manual closing pressure.
  • Tweezers of this type have been known for a long time and in many designs, e.g. in DE GM 85 31 382, CH 376 064 and EP 0 849 048.
  • Such tweezers essentially consist of two legs, usually made of steel, which are connected at one end by welding, soldering or riveting.
  • the force required to close tweezers i.e. the minimum manual closing pressure, sufficient to ensure that the tweezers are properly gripped, must not be so high that the operation is tiring. In other words, the tweezers must not be too “soft” or "hard”.
  • the tweezers suggested in the above-mentioned document are made from a thin sheet of metal from which profiled tweezer legs are formed, e.g. can be joined together by seam or spot welding. This means that sheet metal made of a material such as steel must be used, which can be processed in this way.
  • Tweezers are made of light metal, yet have the essential mechanical properties of the well-known forged tweezers and were easy and economical to manufacture.
  • a first object of the invention is therefore to provide tweezers made of light metal with the mechanical properties essential for forged tweezers.
  • a second task is to provide a method for the economical production of such light metal tweezers.
  • a pair of pliers for handling compact disks (CDs) is described, which is made of spring steel, plastic, aluminum, copper, brass or composite material and grip a CD both on the outer edge and on the edges of a central opening can.
  • the leg ends are not closed, as is the case when using tweezers.
  • Pliers of this type therefore inevitably differ both in the mechanical properties and in the shape of tweezers.
  • the shaft and the jaw-shaped tool are made of aluminum or aluminum alloy and are coated with aluminum nitride
  • the invention relates to a pair of tweezers of the type defined in the input section, ie with two legs, each with one end are in connection with one another and can be brought together for temporary and reversible engagement at their other ends by the action of a manual closing pressure, and is characterized in that the tweezers essentially consist of preferably extruded light metal and are formed in one piece
  • the term "in one piece" in connection with tweezers is intended to mean that the light metal of the two legs is completely homogeneous even in the area of their common apex area, i.e. is neither a mechanical nor a connection produced by welding, let alone soldering or gluing.
  • the tweezers according to the invention exist in other words from a single integral workpiece (ie not like forged tweezers from two interconnected parts) and normally has no additional functional parts. The use of additional spring elements should thus be excluded, especially since the spring elasticity of a pair of tweezers according to the invention is completely sufficient in itself.
  • Essentially consisting of light metal here means that the tweezers consist of light metal in all essential parts. However, this does not rule out the use of top coat, decorations, plastic coatings or coverings, for example for electrical insulation, or the like
  • the closing pressure of a pair of tweezers according to the invention should generally be at least about 120 g, preferably at least about 150 g and typically at least about 200 g.
  • the manual minimum pressure that must be exerted on a pair of tweezers is referred to here. in order to bring the "lower” ends of the legs, which are distant from one another, into contact with one another but do not yet exert any additional pressure for grasping an object.
  • the "upper” or “proximal” end of the legs is the apex region which forms the transition between the legs and accordingly the "lower” end denotes the opposite end or "distal" end to the apex area.
  • the closing pressure is also an expression of the resilience or resilience of the tweezer legs and should not occur under normal conditions, even if the tweezers are used for practically any length of time not significantly change
  • the qualification of numerical data by "about” should indicate here and below a permissible deviation of ⁇ 15% from the specified value.
  • the closing pressure can be determined relatively easily with an accuracy sufficient for the purposes of the invention, e.g. by means of a letter scale and observing the value of the difference between the tweezer's own weight and the load which is required to bring the distal ends of the tweezer legs into contact with one another
  • the manual pressure used to grasp an object is usually several times higher than the closing pressure. Accordingly, it is essential for the functionality of a pair of tweezers according to the invention that they have any direct, ie. can withstand manual pressure that can be achieved without tools or aids without permanent deformation.
  • This method for producing a one-piece light metal tweezers represents a further embodiment of the invention and is characterized by the provision of a light metal extruded profile with a cross-sectional shape that approximately corresponds to the tweezers to be produced and the dismantling of the profile at least approximately transversely to its longitudinal (or axial) direction in a plurality of tweezers or tweezer moldings.
  • the determination "at least approximately transversely to the longitudinal direction” should include a deviation of up to approximately 15 ° (corresponding to an intersection angle of up to approximately 75 ° or a deviation of 1/6)
  • a closed profile is used for this. This can be separated at an angle before or after the cross cutting at the lower end to form claws.
  • a light metal extruded profile with a cross-sectional shape that corresponds at least approximately to the shape of a pair of tweezers represents a further embodiment of the invention.
  • Such a profile is preferably designed as a closed profile, ie it describes a space that is closed in the radial direction, meaning “radial” a direction running perpendicular to the axial or longitudinal direction (e.g. the extrusion direction of an extruded profile) of the extruded profile.
  • the longitudinal direction of a pair of tweezers according to the invention runs from their upper end to their lower end.
  • extruded profile here is a semi-finished product with a defined cross-sectional profile and any length ⁇ obtained, as can be obtained by extrusion or extrusion.
  • the extruded profile according to the invention essentially consists of a light metal composition which is known to those skilled in the art as being suitable for producing extruded profiles or can be recognized by them as being suitable for this purpose
  • extruded profile material as a semi-finished product for the production of tweezers according to the invention is a preferred feature primarily for reasons of economy.
  • profiles according to the invention can be obtained by various shaping methods, such as drawing or pressing, in principle - but at normally prohibitive manufacturing costs - light metal tweezers according to the invention can also be produced individually, for example by casting, by drop forging or other one-off processes, so that the Production via light metal profiles is preferred for economic reasons functional is not necessarily critical, as long as the properties of the metal structure obtained are comparable to those of an extruded and / or extruded profile.
  • tweezers can be simplified in an almost dramatic manner according to the invention. Whereas prior to the invention for the production of tweezers with the essential properties of forged tweezers, numerous manufacturing steps were required which practically excluded an essentially automatic production, the production is reduced to the provision of a single semi-finished product, the extruded profile according to the invention, and its disassembly into one Variety of tweezers. Both can be largely automated and practically completely automated when using closed profile material, as will be explained in more detail below.
  • tweezers according to the invention have a material reinforcement or thickening in the apex area and / or near the lower leg ends in accordance with a preferred embodiment for controlling the essential mechanical tweezer properties (i.e. a sufficiently high closing pressure and high resistance to permanent deformation)
  • thickening is understood to mean an enlargement of the "normal" thickness of the legs of the tweezers in some areas. Typically, these areas are at least 20% thicker than the normal thickness of the legs.
  • the "normal" thickness of the legs is the reference thickness in predominant part of the legs between the lower end of the tweezers (working end) and the upper end of the tweezers (apex area). Thickening of the legs is usually limited to a maximum of about a third (33%) of the entire length of the tweezers, is located in the vicinity of the lower end of the tweezers and is practically the same shape on both legs.
  • the legs of a pair of tweezers according to the invention can be known per se at their lower ends, at which they can be brought into engagement with one another Be claw-like and / or tapered.
  • the legs generally have a prismatic and preferably approximately rectangular cross-section in the area between their ends, the height of which corresponds to the normal thickness of the legs and the width of which is at least twice greater than the normal thickness 20% thickened and mostly formed on the inside as a rounded surface.
  • this is not critical if the microstructure, in particular crystallinity, of the light metal used ensures a sufficient closing pressure even without thickening of the material.
  • a possible thickening of the legs is usually in the bottom third of the legs, i.e.
  • the thickening of the legs is dimensioned such that they are in contact with one another in the case of manual pressure which could lead to permanent deformation of the legs. This increases the resistance to deformation up to the range of forces or pressures that lead to cold material deformation of the light metal, which is of course far above the maximum manually exerted pressures.
  • FIG. 1 is a side view of tweezers according to the invention or the light metal profile from which it is made;
  • FIGS. 2 to 5 show some examples of modifications to the crest area of tweezers according to the invention, and
  • FIG. 6 shows an example of a preferred extruded profile according to the invention
  • FIG. 1 shows the semi-schematically illustrated side view of the tweezers 10 or the light metal profile, from which the tweezers have been produced by cutting or tearing the profile at least approximately perpendicular to the longitudinal direction of the profile to form a sequence of profile pieces, preferably with at least approximately the same width is
  • the legs 12, 14 extend from their claw-like ends 121, 141 to the apex region 13, in which they merge into one another continuously.
  • the apex region 13 can be designed as a thickening in that its thickness at the cross section of the longitudinal axis of the tweezer 10 running through the apex S is at least 20% thicker than the thickness of the legs 12, 14 which merge into the apex region 13
  • the inner surface I of the apex region 13 marked with the transfer number 130 is curved in the shape of an arc or semicircle; the shape of the outer surface can be chosen to be similar or different, as long as a sufficient thickness of the apex region 13 is ensured in the apex region.
  • the ends 121, 141 can be further machined into another desired shape, for example to form beveled, pointed or beveled ends, but this is not considered essential for the invention.
  • the legs 12, 14 can be provided near the claw-like ends 121, 141 or near the apex region 13 with thickenings 171, 172 and 151, 152 in order to limit the deformation of the tweezers 10 when exposed to excessive manual actuation pressures and thereby a practical one to achieve any resistance to permanent deformation
  • the legs 22, 24 merge one into the other in an apex region 23 which runs at an acute angle to the apex S, the inner surface I again being arcuate or approximately semicircular.
  • this is also a preferred and not a critical condition, since an embodiment of a pair of tweezers according to the invention as shown in FIG. 3 is also possible, in which the legs 32, 24 merge into one another in an apex region 33, the apex S and the inner surface I of each run at an acute angle to each other
  • the embodiment of the crown region 43 shown in FIG. 4 shows a further example of a pair of tweezers according to the invention, in which the legs 42, 44, which merge into one another in the crown region 43, have depressions at the transition to the inner surface I, as they do to set the desired closing pressure - tweezers according to the invention can be used.
  • the generally arcuate embodiment of the apex region 53 shown in FIG. 5 is not shown thickened at the transition of the legs 52, 54 for the purpose of explanation. Such execution is normally not preferred and should be secured (in a manner not shown) by means of a thickening in the lower leg area against deformation of the tweezers.
  • Such a design of the upper end of the tweezers requires an extruded light metal profile - ie it must not be formed by bending, as this normally leads to a considerable weakening of the metal structure.
  • an extruded profile has a homogeneous structure. Appropriate extrusion processes can sometimes increase the strength of the metal structure.
  • FIG. 6 shows the cross section of an extruded profile 60 with an upper end 61 thickened to approximately 300% (thickening factor 3) and with two legs 62, 64 which thickened in the vicinity of the lower leg ends 65, 67 to approximately 200% (thickening factor 2) are.
  • the longitudinal (or axial) direction of the extruded profile 60 runs perpendicular to the plane of the drawing, the transverse (or radial) directions lie in the plane of the drawing
  • the extruded profile 60 is a closed profile, i.e. it comprises a space 63 which is closed on all sides in the radial directions. Accordingly, the lower profile end 69 is also closed and, in order to produce the finished tweezers, not only has to be disassembled into a plurality of tweezers or tweezer moldings by transverse separation (radial parting plane), but also before or after the cross separation also in the axial direction.
  • the closed extruded profile 60 shown in FIG. 6 is formed at the lower end 69 in such a way that not only the closed profile is opened by a separation in the plane of separation indicated by the dash-dotted lines T and extending in the axial direction, but at the same time an expedient shape of the lower ends of the tweezers 65, 67 is formed, which are at a distance A from one another ("open") in the idle state and which have gripping surfaces 651, 671.
  • a pair of tweezers according to the invention formed from the profile 60 by transverse and long separation remains Between the gripping surfaces 651, 671 there is a wedge-shaped space which, when the closing pressure is reached, is initially closed only at its lower end and closes progressively only with increasing manual pressure.
  • This is a known means in known tweezers with a claw-shaped end, in order to achieve a good gripping and holding effect for an object gripped with the tweezers, for example a hair.
  • the angle ⁇ of the separating surface indicated by the lines T is approximately 20 ° when the extruded profile 60 of FIG. 6 is executed, but can be changed within wide limits, for example between 10 ° and 80 °. An angular range of approximately 15-30 ° is preferred for many purposes.
  • the distance D between the thickenings 66, 6S used according to a preferred embodiment in the lower third of the legs is practically the same as the distance A at the lower end 69 of the profile 60 and thus practically the same Distance between the gripping surfaces 651, 671 of a pair of tweezers made from the profile 60 in the idle state, ie with gripping surfaces spaced apart from one another by a distance.
  • a typical pair of tweezers made from a profile of the type shown in FIG. 6 has an overall length of approximately 90, a leg thickness of approximately 2 mm, a leg width of approximately 6 mm, a closing pressure of approximately 200 g and a weight of 2. 5 g.
  • a general range of dimensions lies between half of the values just mentioned and their double.
  • a forged steel tweezers of known type with comparable dimensions and essential properties weigh at least about 6, but typically 8 - 9 g.
  • light metal is understood to mean metals with typical densities below about 4 g / ml, such as in particular aluminum and magnesium and alloys of these light metals with one another and / or with other alloy constituents.
  • the exact composition is not critical in that
  • compositions required for the production of extruded profiles in particular extrusion and extrusion processes.
  • Special examples are commercially available alloys, which mainly contain Al and -Or Mg and mostly also Si and possibly other alloy components.
  • Such alloys are, for example, the light metal alloys corresponding to DI 174S, as are available under the type designations F1, F21, F28, F31 etc., as well as those under the brand names Avional and Perunal available alloys.
  • Advantages of light metal tweezers according to the invention lie not only in the reduced density and mass compared to conventional forged tweezers made of steel and the significantly simplified production from extruded profile material, but also in the fact that the surface design of articles made of light metals, such as in particular aluminum or aluminum alloys, is possible due to the possible oxidation processes. Ren is particularly diverse and is advantageous in terms of both the color options and the surface properties (e.g. thanks to the hardness of aluminum oxide).
  • the invention provides tweezers consisting essentially of light metal, preferably aluminum or extruded aluminum alloys, with two legs, each of which forms an apex region at one end and can be reversibly brought together for temporary engagement at the other ends by the action of a manual closing pressure
  • Tweezers are made of preferably extruded light metal, are made in one piece, and have the essential mechanical properties of forged tweezers, namely a sufficiently high closing pressure, a good grip and holding effect for objects that are detected with the tweezers, and one that is practical under normal use unlimited resistance to deformation.
  • a preferably closed extruded profile with an approximately tweezer-shaped cross section can be used to produce the tweezers, which enables a considerably simplified production
