1 TARIFF IN-MOLD MARKING SYSTEM FOR SUSPENSION BELLOWS AND THIS MARKING METHOD WITH SYSTEM TECHNICAL AREA 5 The invention is an elastic tube suspension element that operates with compressed air. In suspension bellows, permanent information markings are applied to the product using embossed molding. its application based on this principle, especially what is called "sheet metal model marking", This relates to the marking method carried out with beehive and sheet metal logo components. PREVIOUS TECHNIQUE The suspension bellows are made of rubber, textile cord and steel reinforcement rings. it is formed, the vehicle chassis is positioned between the axle and the compressed air inside. It is known that it fulfills its load-bearing and vibration-damping functions thanks to this. Air is pumped into the bellows via a compressor, and as the air pressure increases, the conveying speed increases. the capacity increases and the pressure automatically adjusts according to road conditions and load status. Manual adjustment is also included in the divided state of the technology. Marking on suspension bellows is important for product identification, traceability, Marking is critical in terms of quality control and meeting legal requirements. within the scope of the manufacturer's name or logo, part number, production date, lot or serial number 20 The serial number and origin data are printed onto the bellows during production. In the case of the technology being divided, the most common approach for marking is mold embossing. In this method, a pantograph, which is the working principle of the mold, is used. tracing the tracing motion by mechanically tracing the contour on the template Transfer to the cutting end via the copying mechanism and thus the mold (100) 25 b0r is formed by engraving the logo and letter geometry on the surface (00). The logos and text processed on the c0haz 0le 0le are transferred to the bellows during vulcanization and The marking is made permanent (Figures 1a and 1b). Vulcanization process Placement of rubber and reinforcement layers inside the mold, closing the mold, pressure and ensuring cross-linking of the rubber by holding it under a certain temperature for a specified period of time 30 It consists of the stages of opening the mold and removing the product. This In this way, the brand name processed on the mold is permanently printed on the bellows. The previous technical problem, detailed above, is related to the increasing customer portfolio. b0rl0kte every brand and customer cross number needs to produce separate brand parts 2 Increased costs, processing times and storage space requirements, in addition to The increasing demand for raw materials prolongs the supply process.

Sheet metal logo (300), sleeve (200) no bolt or holder needed an angle defined by a 2° section that provides self-locking without being heard Thanks to geometry, stability is achieved inside the casing during suspension bellows production. It is designed to remain in place. 15 The target of the sheet metal logo (200) used in the trademark system subject to the application This characteristic is described as having "no memory" of temperature changes. It is the ability to return to its original form after the applied force is removed. The goal is to prevent any shape changes from occurring after printing during production. Production during the expansion of the suspension bellows inside the brand part (100) 20 The resulting upward and downward resistance makes it suitable to move the sheet metal logo (300) with a load. to create 0ken, sheet metal logo (300) angled geometry0s0 to fit tightly into the sleeve 0ç0ne and It ensures that it remains fixed to the wall it rests against. Within the scope of the invention... As a result of the trials carried out, ST c0ns0 sheets were used in the production of the sheet metal logo (300). and the targeted yield could not be obtained with DKP c0ns0 sheets; tempered steel C75 25 The targeted technical effect has been achieved with the material. In thickness tests, 0.5 mm, 0.7 mm and 1 mm options were tested and the 0.7 mm thickness, as defined above, was preferred. It was chosen because it was found to be optimal in providing the functions. The sheet metal logo (300) used in the trademark system subject to the application, any b0r without the need for a bolt or retainer, the image on the sleeve (200) is 30 In order to enable self-locking between the slots (210) in the form of 2° b0r kes0m 0le is designed. In this way, during the production of the suspension bellows, d0key Working vulcanization molds (Fig. 6), sheet metal logo (300) logoing process without falling off. It can be realized. The mentioned slots (210) are part (100) of the housing. It contains a space towards the inside, and the sheet metal logo (300) corresponds to these spaces. There are incoming edge protrusions (310). When determining the angle of the sheet metal logo (300), 5° and horizontal lines in the marking area on the bellows during 7° cutting tests and the visual quality is negatively affected, a smooth structure is not formed It was observed that in section 2° (a), the visual quality was found to be optimal, and this 5 The value has been preferred. As shown in Figure 1, the trademark subject to the application stable positioning of the sheet metal logo (300) used in the casing (200) to ensure that the sheet metal logo (300) has at least one angular geometry at one end It is defined. In this context, the angle shown as “a” in Figure 5 is the end of the sheet metal logo (300). Express the amount of deviation of the bending geometry created in the region with respect to the vertical direction. 10 and is set to 2° and the sheet metal logo (300) into the sleeve housing (210) It is determined in such a way as to create a tight fit during installation. In Figure 1, the angle indicated by “b” defines the angle of the bend in question, The bend created in the end region of the sheet metal logo (300) is more than the nom0nal d0k bend It shows that it is structured in such a way that it will be closed. In this context, the angle “a” is expressed as 15. The amount of deviation is such that the angle "b" is 2° less than 90°, i.e., 88° (b). This corresponds to the creation of the sheet metal logo (300) end region of the sleeve (200) pressed into the sockets (210) with the support surface0 elastic rebound and wedge effect00 without using any bolt or retainer, spontaneously inside the sleeve (200). It is ensured that it remains stable without changing its position during locking and production. 20 The method related to the use of the marking system in question, the hive (200) and positioning of the sheet metal logo (300) on the brand part (100), sheet metal logo (300) Keeping stable throughout production and marking during the vulcanization process It is based on the principle of transferring it onto the suspension bellows. Accordingly, In the method, first of all, the sheet metal logo (300) will be placed on the brand part (100). The area defining the casing (200) brand part (100) surface is being machined on the lathe. and sheet metal housing is cut to precise dimensions by wire erosion to form the sleeve (200). After that, the customer logo and cross numbers were laser-etched at a depth of approximately 0.28 mm. The processed sheet metal logo (300), the slots (210) inside the casing (200) and the sheet metal logo The edge protrusions (310) on (300) are aligned so that they meet each other, 30 The beehive (200) is placed inside. During this placement, the tip of the sheet metal logo (300) Angular geometry corresponding to the 2° (a) deviation and 88° (b) angle defined in the region. through sheet metal logo (300) sleeve (200) inner slots (210) elastic rebound and The wedge effect is pressed down and the sheet metal logo (300) is attached to any bolt or holder. 6 It is able to lock itself without needing any additional force. Subsequently, the suspension... The rubber and reinforcement layers to be used in bellows production are the brand part's (100) is placed inside the mold (Figure 6) and closed, then The bellows structure is formed by applying high pressure and temperature under vulcanization conditions. The shaping of the suspension bellows is ensured during vulcanization. The upward and downward resistance caused by the expansion causes the sheet metal logo (300) to move. Although it creates a load, the angled geometry of the sheet metal logo (300) and the edge of the socket (210) Thanks to the interaction of the protrusion (310), the sheet metal logo (300) remains stable inside the sleeve (200). and does not change place. During this process, the customer defined on the sheet metal logo (300) logo and cross numbers, brand part (100) surface marking 10 It is transferred from the region to the suspension bellows surface in the form of relief. After vulcanization is complete, the mold is opened and the marking is made permanent. The suspension bellows, formed as is, are removed from the mold. Subsequently, different customers... logo and / or different cross number 0ç0n marking 0çer0ğ0n0n değ0şt0r0lmes0 If necessary, the casing (200) is protected on the brand part (100) and only sheet metal 15 logo (300) removed from hive (200) and new logo and / or cross number included b0r another sheet metal logo (300) same alignment and self-locking principle beehive (200) It is placed inside and production continues in this way. The trademark system that is the subject of the application aims to respond more quickly to the ever-increasing trademark demands. The rotation is being made, space and shelf requirements in the 0st0fleme area are being reduced, and the pantograph 20 The mandatory radius corner limitation caused by the tool tip radius is eliminated. By removing the existing logo and laser processing, the customer's logo is obtained in a similar way, and the logo quality is improved. It is being increased. In addition, the need for raw material purchases is significantly reduced. Example Compared to producing 100 molds for 100 different brands, the sheet metal that is the subject of our invention... In the model branding approach, this cost is seen to be reduced to 1 / 10. 25 If damage occurs to the sheet metal logo (300), all brand parts (100) will be replaced. only the replacement of the sheet metal logo (300) part will extend the service life of the sleeve (200). It is being extended, the same customer and the same product have different cross numbers. when single b0r sleeve (200) 0le different sheet metal logos (300) are produced molds can be made and customer agreement completed, shells (200) 30 without being scrapped It can be reused as a brand part (100). No, it is done with the sheet metal logo (300) inside the hive (200). This Therefore, the part that needs to be changed is the sheet metal logo (300).
