Description

1 TARIFF A lightweight connection compatible with standard drive devices. EMPLOYEE TECHNICAL FIELD The invention relates to a fastener with a hole. PREVIOUS TECHNIQUE 10 Fasteners are mechanical components used to hold different parts together. Widely used in many industrial fields, particularly automotive and construction. It is used. Axial rotation is achieved by applying torque to the fastener during the assembly of the parts. This process is carried out by either using the external hexagonal or internal drive of the connecting element. This is done using appropriate sockets, kits, or similar actuating devices. However In fasteners with external or internal drive forms, contacting clamping devices There is a certain tolerance between the surfaces. Due to this tolerance, tightening and loosening takes 20 minutes. The torque applied during these operations usually covers a smaller portion of the contact surface rather than the entire contact surface. and is transmitted through limited areas. In fasteners with external or internal drive types, contacting the clamping devices. There is a certain gap between the surfaces due to manufacturing tolerances. This 25 the torque applied during opening, tightening and loosening operations, instead of the entire surface This results in transmission through more limited contact areas. Non-contact The surface areas do not provide any functional contribution and remain unused during assembly. The material in these areas is excessive for the fastener. This causes it to have weight. 30 In studies aimed at reducing weight, these often non-functional areas are targeted. New designs are being developed by extracting and removing waste materials. In this context, discarded materials are being used. This is reduced from the external geometry of the fastening element. However, this approach is design-wise... This leads to restrictions, and weight reduction is limited to around 25% in most cases. 35 It remains. 2 In weight reduction designs, changes are made to the shape of the fastener. The applied torque causes deformations and loss of the original geometry. This can happen. This situation negatively affects the rigidity and structural integrity of the fastener. It can have an impact. On the other hand, the connector was developed for use only with special drive devices. While changes in the form of the elements result in greater material savings, The fact that assembly operations can only be performed with these special tools; the supply process This makes things more difficult and leads to additional costs. Consequently, weight is a factor in fasteners that can be driven with standard clamping devices. The reduction remains limited; designs compatible with specific drivetrains are operational and This creates new economic constraints. In the known state of the art, fasteners generally feature symmetrical mirroring. 15 extensions (or extensions) created with the principle of having equal geometric repetition in both directions (ears) are used. In these designs, an equal number of contacts are used in the tightening and loosening directions. There is a point where equal torque transmission is aimed for in these directions. However, assembly The tightening torque required to achieve the locking force during this process is determined by the elastic properties of the system. Due to interactions and friction conditions, it is higher than the loosening torque. 20 These high torque values ​​are applied if there are a sufficient number of tubes with sufficient surface area. If there are no contact areas, it will cause stripping between the drive device and the connecting element. This can happen. This situation leads to local plastic deformations in the contact areas and By preventing torque transmission, it makes tightening or loosening the fastener impossible. 25 This enables the assembly process to be carried out safely and functionally. It is not possible to complete it. In the known state of the art, the connection is usually designed to prevent the stripping problem. The element has the same geometric shape as the region where torque is applied and has a wider contact area. 30 Special drive devices are used to provide the surface. Alternatively, sufficient key The elevation of this area is being increased in order to create a contact area. However, these... This leads to the use of extra material in the fastener and consequently an increase in weight. It opens. 35 In conclusion, all the problems mentioned above necessitate an innovation in the relevant technical field. It has made it mandatory. 3 A BRIEF DESCRIPTION OF THE INVENTION The present invention aims to eliminate the aforementioned disadvantages and contribute to the relevant technical field. It is related to a fastener, with the aim of bringing new advantages. One purpose of the invention is to achieve the desired torque and / or clamping force during assembly. where the stripping problem does not occur and thus the necessary locking for a secure connection is achieved. a shaft-mounted connecting element that makes it possible to create the connections required. to reveal. Another purpose of the invention is to provide a special actuator for tightening and loosening operations during assembly. Compatible with standard hexagonal head drills without the need for an adapter. The goal is to create a connecting element that can function in this way. Another aim of the invention is to create a lightweight and high-performance 15 in line with current industrial trends. Unlike traditional fasteners, it supports the use of durable components. The goal is to create a nut-type fastener with a special shape. Another aim of the invention is to have an equal number of wrenches in the tightening and loosening directions compared to the known technique. In contrast to torque transmission via the point and area of ​​contact, there are 20 different situations. As such, more torque is applied to the key contact points in the tightening direction compared to the loosening direction. The goal is to create a connecting element that enables transmission. Another aim of the invention is to eliminate the problem that negatively affects assembly performance when torque is applied. In cases where the areas affected by the resulting axial rotational forces are insufficient, 25 The aim is to provide a solution to the stripping problem that arises. In this context, before stripping occurs, providing sufficient contact area and less contact compared to traditional hexagonal head designs. A connecting element with a point has been introduced. Another aim of the invention is to create a design that differs from traditional hexagonal forms, with 30 Created without symmetrical mirroring, and with contact areas connected by concave arcs. thanks to a structure to which it is connected, the amount of material is significantly reduced, therefore The goal is to develop a lighter fastening element. Another objective of the invention is to ensure that the fastener is 35 during tightening and loosening operations. The reduction in material in this form leads to deformation in the key contact geometry and The aim is to prevent the loss of form. In this context, the rigidity of the form is preserved. 4 The drainage system, unlike traditional designs, is located in the center of the connection element. It was realized based on the characteristic boundary geometry. Accordingly, in a prismatic structure And thanks to this drainage system, which is created in a way that avoids axial symmetry, higher Material savings are achieved in proportions, and the total weight is reduced. Another purpose of the invention is to improve the shaping production applied within the scope of the cold forging process. The goal is to create a fastening element that conforms to these methods. All the purposes mentioned above and those that will emerge from the detailed explanation below. The present invention relates to a fastening element with a hole. This is called 10 According to the innovation, it can be assembled with substandard corner drive devices and its weight is reduced. at least two units, each containing at least one of the following: a disassembly contact surface and a tightening contact surface. the inclusion of a contact area and the number of clamping contact surfaces mentioned, the mentioned disassembly The number of contact surfaces is greater than the number of surfaces.

Thus, easy integration into externally threaded structures is ensured, simplifying the assembly process. It is being simplified. A characteristic feature of a possible design of the invention is that the aforementioned hole is threaded. Thus, 20 Connections can be made using threaded structures such as bolts. A characteristic feature of a possible design of the invention is that the number of contact areas is four. Thus, the rigidity and deformation resistance of the connecting element are ensured during torque transmission. Weight can be reduced while maintaining the same level of protection. 25 A feature of a possible design of the invention is that the two contact areas are each only a single clamp. It contains a contact surface. Thus, disassembly is done without a contact surface, in the disassembly direction. Material reduction is possible, resulting in weight savings. A feature of a possible design of the invention is that both contact areas are both clamping contact surfaces. It also contains a disassembly contact surface. Thus, the fastener can be used in both directions. It enhances assembly safety by providing balanced torque transmission. A characteristic feature of a possible configuration of the invention is that there are four squeezing contact surfaces. 35 Thus, the high torques generated during the tightening process are spread over a wider area. The risk of stripping is reduced, thanks to the traditional six-compression contact surface connection. The weight can be reduced depending on the components. A characteristic feature of a possible design of the invention is that the disassembly contact surfaces are two. Thus, sufficient contact is provided for the loosening process while the conventional six-point disassembly contact 5 unnecessary material usage, such as in fasteners with a surface It is being blocked. A characteristic feature of a possible design of the invention is the radius value between the contact areas. a first arc, a second arc, a third arc, and a fourth arc, decreasing in order. 10 It has a curved shape. Thus, material usage is optimized and weight is reduced. While the reduction is complete, structural integrity is preserved. The characteristic of a possible construction of the invention is the first curve mentioned, the second curve mentioned. the curve, at least one of the aforementioned third curve and the aforementioned fourth curve is concave 15 It is a spring. Thus, deformation is optimized by optimizing the stress distribution in the transition regions. The risk is reduced and the weight is decreased by creating voids. A feature of a possible design of the invention is the connection element of the drive apparatus. After installation, the first curve, second curve, third curve, and fourth curves are driven. 20 at least one of the following resulting from the removal of material from the section between the apparatus It contains a void. Thus, the total weight of the fastener is reduced during production. Costs are being reduced.

DETAILED DESCRIPTION OF THE INVENTION 15 In this detailed description, the subject of the invention, the fastener (1), is only to better explain the subject. It is explained with examples that do not create any limiting effect on understanding. Figure 1 shows a representative isometric view of the connecting element (1) that is the subject of the invention. 20 The present invention overcomes the aforementioned disadvantages in the prior art. Lightweight and high-strength components are coming and becoming one of the industrial trends. a new generation with a special form developed to be the counterpart in fasteners It is related to the fastener (1). Although the fastener (1) is essentially a nut, the torque 25 female fittings such as plugs, sleeves, couplings, etc., that operate by being applied and have similar functionality. It is obvious that they may also have members. As shown in Figure 2, the connecting element (1) can contain at least one flange (80). The circumference of the flange (80) is similar to conventional hexagonal flange fittings (1), It is the part that has the widest diameter. In addition, with regard to the aforementioned flange (80), 30 The flange angle located on the upper surface of the nut is between 3° and 10°. Preferably this. The angle is between 5° and 7°. Furthermore, this flange angle is compatible with conventional hexagonal flange connections. It is lower in terms of flange (80) in its (1) elements. Thus, cold forming to facilitate production during the process and to adjust the nut height To facilitate this, an optimum flange angle value was obtained. 35 7 The connecting element (1) has an asymmetrical form. In other words, geometrically It was created without symmetric mirroring. Here, "without symmetric mirroring" The expression means that the form of the connecting element (1) is symmetrical along the axis of both sides not created by copying from one side, but instead possessing different geometric characteristics This design approach is based on the material used in the connecting element (1). reducing the amount and at the same time optimizing torque resistance It provides. The connecting element (1) is a device that allows at least two actuators (T) to apply force. It contains several contact areas (10). In the preferred configuration, the contact areas (10) are shown in Figure 10. There are four of them, as shown in 3. These contact zones (10) are axially formed during assembly. It is designed not to deform under rotational force. Drive The apparatus (T) torques the outer surface of the connecting element (1) through the contact areas (10). by applying the element to be rotated in the tightening direction (I) or the loosening direction (II). In practice, the drive device (T) is a standard hexagonal wrench 15 This is possible (See Figure 6). The aforementioned contact areas (10) are applied in the tightening direction (I) by means of the drive apparatus (T). the transmission of the axial rotation force created by the torque to the connecting element (1) providing, the drive apparatus (T) used, i.e., the substandard corner boring machine, with its surfaces 20 It contains at least one squeezing contact surface (11) in contact. In the preferred configuration, The squeezing contact surface (11) is four in number, located in each contact area (10). The dimensional dimensions of the clamping contact surfaces (11) are based on the main standard of the fasteners (1). “ISO 898-1 - Mechanical properties of fasteners made of carbon steel and alloy steel Part 25 1: Bolts, screws and studs with specified property classes — Coarse thread and fine pitch The highest fastening element (1) defined within the scope of "thread" has a strength class of 12.9. corresponding to its strength values ​​and “ISO 898-7 - Mechanical properties of fasteners Part 7: Torsional testing and minimum torques for bolts and screws with nominal Minimum fracture torques given within the scope of the "diameters 1 mm to 10 mm" standard are 30. It is determined according to the sufficient key contact areas that will provide. The most important factors affecting the performance of fasteners under assembly conditions (1) To reach the locking load, which is one of the parameters, the load applied during the tightening process... The magnitude of the axial rotational force generated in the contact areas (10) with the torque is important. 35 Contact areas (10) cause the fastener (1) to lose its functionality during tightening. axial rotation force generated at the highest torque values ​​causing this 8 even when applied, resistance to abrasion in the aforementioned contact areas (10) It has been optimized to provide this. To provide the locking load required for the assembly of the fasteners (1) The applied tightening torque reduces the elasticity between the assembly parts and fasteners (1) 5 Due to the interaction and friction conditions, loosening of the connecting element (1) It is higher than the required removal torque. Therefore, the fastener (1) For the transmission of the loosening torque to the fastener (1) to be applied for loosening A smaller contact surface (10) is sufficient compared to squeezing in direction (II). In the contact area (10), the axial torque created by the applied torque in the loosening direction Standard used to ensure that the rotational force is transmitted to the connecting element (1) At least one disassembly contact surface in contact with the surfaces of the hexagonal boring machine (12) It is located. In accordance with the information stated in the paragraph above, the aforementioned dismantling The contact surface (12) is two in the preferred configuration. In other words, Figures 8 and 15 As can be seen in Figure 9, only two of the four contact areas (10) have disassembly contact. while there is a surface (12) in each contact area (10) the squeezing contact surface (11) This prevents a stripping problem during the loosening process. without incident, the connecting element (1) is securely screwed to the element to which it is screwed It can be disassembled. Disassembly contact surfaces (12) in the contact areas (10) 20 There are. That is, the disassembly contact surfaces (12) axial rotation in the disassembly direction (II) to distribute the force evenly to the key-holding surfaces, not side by side, They are located in the mutually contact zones (10). In the preferred application, two clamping contacts 25 are placed between the two disassembly contact surfaces (12). There is a surface (11). Thus, the forces to be applied to the connecting element (1) are more By ensuring balanced and stable transmission, it prevents potential slippage. Therefore, two of the four contact zones (10) are passed. (10) containing only the clamping contact surface (11) and the disassembly contact surface in these areas (12) With the reduction of the material to be formed, material use has decreased and 30 The weight has been reduced. As can be seen from above, as in Figure 9, the mounting of the connecting element (1) in areas that do not come into contact with the key, in a way that will not negatively affect its performance The weight of the fastener (1) was reduced by reducing the material. In this context, 35 discharges are located between two opposing contact surfaces (10) and are bounded by concave arcs. are gaps (60). 9 The height of these gaps (60) is equal to the key holding height of the connecting element (1) It is designed to be the same. This can be seen in Figure 7. The gap (60), drive After the apparatus (T) is attached to the connecting element (1), the drive of the connecting element (1) The parts of the drive apparatus (T) other than the contact areas (10) that come into contact with the apparatus (T) It is formed between them. To make it more understandable, the gap (60) is the connection element (1) 5 its form, in a way that does not cause a loss of rigidity and strength, between two contacts It is created by reducing the material between region (10) and the connecting element (1) It helps to reduce its weight. As a result of the voids (60) it contains, the connecting element (1) is 10 respectively, as shown in Figure 4. a first curve (20), a second curve (30), a third curve (40) that makes it asymmetric and includes a fourth curve (50). That is, four contact zones (10) are connected to each other. the first curve (20), the second curve (30), the third curve (40) and the fourth curve mentioned respectively They are connected by means of the curve (50). Therefore, the mentioned curves (mentioned The curves referred to are the first curve (20), the second curve (30), the third curve (40) and the fourth curve 15 (50) is located between two contact zones (10). The curves are concave arcs. It is shaped and has a radius value. Since there are four curves, there are also four spaces. (60) is available. As a result, the contact areas (10) are a straight line as in the current technique. They are connected not by lines, but by curves. In other words, to reduce the use of material in the fastener (1) To create the mentioned curves, voids (60) are created by removing material. The radius values ​​of the curves from the first curve (20) to the fourth curve (50) are shown in Figure 2. As can be seen, it is getting smaller. This creates an asymmetrical form. The gradual reduction in the radius values ​​of the curves, material usage and connection 25 It creates a balance between the rigidity of the element (1). In this way, the connection element (1) maintaining structural strength while reducing weight and optimum material use This is possible. In addition, this allows for 4 contact points instead of 6 contact points (10). The use of region (10) is possible. The connecting element (1) has at least one hole (70) in the central region. The hole (70) The inner wall has a toothed structure as shown in Figure 5. The mentioned hole (70) is toothed Thanks to its structure, the fastener (1) can be attached to a male fastener such as a shaft and / or bolt. It can be mounted. The hole (70) can also be in a lobular structure. Here, the lobular By structure, we mean the radial 35 between the central axis of the hole (70) and the inner surface that limits the hole. the distance is not constant circumferentially, meaning the cross-section of the hole is non-circular, It has a contour with a variable radius. Considering the general form of the discharge zones (60), the formation of sharp edges To prevent this, transition zones are structured with arc profiles. Another In other words, a certain radius value between the contact zones (10) and the discharges (60). It is located. In addition, the space between the aforementioned gaps (60) and the hole in the center (70) and Material thickness defining the inner and outer geometric boundaries of the fastening element (1), clamping and optimized to prevent stripping problems from occurring during loosening operations. The depth of the gaps (60) and the hole (70) where the connecting element (1) will be used has been determined. 10 in accordance with metric measurements and ensuring maximum material efficiency. It is determined. The dimensions of the form of the connecting element (1) are chosen in accordance with different metric values. The design can be revised according to the required key widths. Connection In order to increase the usability of the element (1), each geometric feature in its form and 15 The size is determined based on a specific ratio coefficient according to the key width measurement. It is scaled. The flange diameter in the said connection element (1) is the desired seating. This is determined according to the surface area requirements of the bearing surface. In this way... Connection security is increased by reducing the risk of the connection loosening. The characteristic external form of the fastener (1) conforming to the invention is determined by the cold forging method and This has been determined in accordance with the shaping techniques used within this method. In this way, in applications where reduced weight fasteners (1) are needed, The subject of fasteners (1) can be produced in high volumes, quickly and efficiently. It is becoming. 25 In light of all these explanations, the connecting element (1) subject to the invention is as follows: It is used to: provide the locking load required during assembly. The applied tightening torque creates an elastic gap between the fastener (1) and the assembly components. Due to interactions and friction conditions, the torque value required for disassembly is 30 It is high. Therefore, of the four contact areas (10) located in the connecting element (1) only two of them have a disassembly contact surface that serves to transmit torque in the disassembly direction (II). (12) are located (see Figure 2). The contact areas on the left and right sides in Figure 2 are (10) Since it contains only clamping contact surfaces (11) specific to the clamping direction (I), in these areas Material reduction has been achieved. In addition, the contact areas (10) are connected to each other by 35 in the connecting transition areas, four to achieve material reduction without reducing strength There are (60) gaps. These gaps (60) are respectively the first curve (20), the second curve 11 (30), forming the third curve (40) and the fourth curve (50), connecting It contributes to reducing the total weight of element (1). Finally, the hole (70) located in the center of the connecting element (1) of the connecting element (1) It enables connection with threaded elements. During assembly, a 5 is made through the hole (70). It is passed through a bolt-like fastener (1). Then the wrench is tightened in the tightening direction (I) When rotated, force is transmitted to the clamping contact surfaces (11) of the fastener (1) tightening is ensured; by turning in the direction of removal (II), the removal contact surfaces are made. (12) By applying force, the connecting element (1) can be safely removed. Therefore, the connecting element in question (1) of the invention is the conventional discharge form. conversely, axially symmetric, created by referencing the characteristic main boundaries of the form. non-existent gaps (60) and four contact zones (10) and only two of them With the presence of the disassembly contact surface (12), the strength of the connecting element (1) Much higher weight gains can be achieved without reducing the weight. Thanks to this, 15 By eliminating unnecessary materials, the weight is reduced by at least 30%. This is achieved and costs are reduced due to the use of less raw materials. In conclusion, it is a high-strength material that can be mounted with substandard corner drive devices (T). A significantly reduced weight connecting element (1) has been developed. 20 The scope of protection of the invention is specified in the claims attached hereto, and these details are strictly adhered to. The explanation cannot be limited to those given for illustrative purposes. Because a technically skilled person... the person, without deviating from the main theme of the invention, in light of what has been described above, similar It is clear that this can lead to the emergence of new structures. 25 12 REFERENCE NUMBERS GIVEN IN THE FIGURE 1 Fastener Contact Zone 11 Squeezing Contact Surface 5 12 Removal Contact Surface First Arch Second Arc 40 Third Arc 50 Fourth Arc 10 60 Spaces 70 Holes 80 Flanges (I) Clamping Direction (II) Removal Direction 15 (T) Drive Device
