[0002] During the manufacturing and installation of bridges, it is an important process step to mark the name and direction of the bridge. Traditional bridge name and direction marking tools usually use a fixed lower mold and an upper mold to form the required text or pattern on the bridge surface by closing the upper and lower molds. However, this traditional tool has many shortcomings.

[0003] Firstly, traditional embossing tools need to design and manufacture corresponding lower moulds according to different bridge name and direction identification requirements, which not only increases the manufacturing cost, but also requires a lot of time and manpower to replace the lower mould each time, seriously affecting the production efficiency; secondly, during the embossing process of traditional embossing tools, the contact between the lower mould and the bridge surface is often uneven, which can easily cause the bridge to deform during the embossing process, thereby affecting the clarity and aesthetics of the identification; in addition, when the bridge name or direction identification to be embossed is more complex or there are more of them, traditional embossing tools often cannot meet the requirements. This is because complex identification requires a more complex lower mould design, and a large number of identifications require frequent replacement of the lower mould, further reducing production efficiency.

One end of the second telescopic rod 9 passes through and is slidably connected to the inside of the first telescopic rod 8. The left and right ends of the strong spring 10 are fixedly sleeved on the first telescopic rod 8 and the second telescopic rod 9. When the aluminum plate is subjected to the downward pressure of the I-shaped embossing die 17, the paved fine sand 3 can evenly support the aluminum plate. When the font logo protruding at the lower end of the I-shaped embossing die 17 further presses the aluminum plate downward to deform it, due to the gaps between the fine sand 3, it will flow by itself after being subjected to a certain pressure, thereby making an indentation matching the pressure, and then through the fine sand The adaptive characteristic of the sand 3 when subjected to stress can not only provide a perfect support effect for the aluminum plate and prevent excessive deformation, but also, compared with the traditional embossing method, the device does not need to replace the lower mold accordingly for the I-shaped embossing mold 17 with different contents, which not only improves the embossing efficiency and reduces the workload, but also reduces the production and expenditure of the lower mold, and ideally reduces the embossing cost. Furthermore, when there are many logos such as the name of the bridge, the gap between the fine sand 3 is not enough to make corresponding changes through operations such as flow and compaction, that is, when the pressure is greater than the elastic force of the strong spring 10, the fine sand 3 will push the sealing plate 5 to slide towards the inside of the transfer slot 4, so that part of it can be The fine sand 3 enters the interior of the transfer trough 4, thereby reducing the blocking effect of the fine sand 3 on the aluminum plate, so that the I-shaped embossing mold 17 can reach a certain depth standard when embossing the aluminum plate, thereby ensuring the production quality of the product and the feasibility of this solution. In addition, compared with the traditional sliding limit design, this solution not only supports and limits the sealing plate 5 through the cooperation of the uniquely shaped T-shaped piece 6 and the slide groove 7, but also when the sealing plate 5 slides inward, the fine sand 3 entering the transfer trough 4 will not enter the slide groove 7, thereby avoiding the wear of the fine sand 3 on the precision structure when entering the gap, improving the service life of the device, and ensuring the rationality of the structural design.

[0021] See also Figure 3An electric push rod 11 is fixedly installed in the middle position of the inner wall of the transfer tank 4. There is a certain gap between the output end of the electric push rod 11 and the sealing plate 5. Finally, the sealing plate 5 that may not be reset can be pushed to the opening of the transfer tank 4 by opening the electric push rod 11, thereby ensuring the flow change ability of the fine sand 3 itself when making simple markings.

[0022] See also Figure 2 A soft thin pad 12 is placed on the upper end of the fine sand 3 inside the sand trough 2, and the upper end surface of the soft thin pad 12 is flush with the upper end of the sand trough 2. The soft thin pad 12 can not only prevent the fine sand 3 in the sand trough 2 from overflowing, but also prevent the fine sand 3 from causing dents and other scratches on the aluminum plate when the pressure is high, thereby ensuring the rationality of the structure. The soft thin pad 12 has a certain deformation performance, and can make corresponding deformation to the convex mark at the lower end of the I-shaped embossing die 17 in cooperation with the fine sand 3, thereby avoiding the influence on the pressed character groove.

[0023] See also Figure 4 A hydraulic cylinder 13 is fixedly installed at the middle of the upper end of the embossing machine frame 1, and the lower end of the hydraulic cylinder 13 penetrates the embossing machine frame 1 and is fixedly installed with a lifting platform 14. Guide rods 15 are fixedly installed at the four corners of the embossing machine frame 1. The four corners of the lifting platform 14 penetrate and are slidably connected to the outside of the guide rod 15. The lower end of the lifting platform 14 is fixedly connected with a slide rail 16 near the left and right sides. A detachable I-shaped embossing mold 17 is slidably installed between the inside of the slide rail 16, and the rear end of the slide rail 16 is fixedly connected There is a baffle 18, and the I-shaped embossing die 17 is adapted to the size of the sand trough 2. First, the I-shaped embossing die 17 is installed inside the slide rail 16. Through the setting of the baffle 18, the I-shaped embossing die 17 is installed so that it can be against the baffle 18. It is convenient and quick to load and unload different I-shaped embossing die 17. At this time, the I-shaped embossing die 17 corresponds to the sand trough 2. By starting the hydraulic cylinder 13, the lifting platform 14 is driven to lower the I-shaped embossing die 17, so that the aluminum plate placed on the upper end of the sand trough 2 and the fine sand 3 is embossed.

[0024] Working principle: First, install the I-shaped embossing die 17 into the interior of the slide rail 16. Through the setting of the baffle 18, when the I-shaped embossing die 17 is installed, it can be pressed against the baffle 18. It is convenient and quick to load and unload different I-shaped embossing die 17. At this time, the I-shaped embossing die 17 corresponds to the sand trough 2. By starting the hydraulic cylinder 13, the lifting platform 14 is driven to lower the I-shaped embossing die 17, so that the aluminum plate placed on the upper end of the sand trough 2 and the fine sand 3 is embossed. When the aluminum plate is subjected to the downward pressure of the I-shaped embossing die 17, the fine sand 3 treated by paving can evenly support the aluminum plate. When the protruding font logo at the lower end of the die 17 further presses down the aluminum plate to deform it, the fine sand 3 will flow by itself after being subjected to a certain pressure due to the gaps between them, thereby making an indentation matching the pressure. The self-adaptive characteristics of the fine sand 3 under force can not only provide a perfect support effect for the aluminum plate to prevent excessive deformation, but also, compared with the traditional embossing method, the device does not need to replace the lower mold according to the I-shaped embossing mold 17 of different contents, which not only improves the embossing efficiency and reduces the workload, but also can reduce the production and expenditure of the lower mold, which is more reasonable. The cost of embossing is reduced. Furthermore, when there are many marks such as the name of the bridge, the gaps between the fine sand 3 are not enough to make corresponding changes through operations such as flow and compaction, that is, when the pressure is greater than the elastic force of the strong spring 10, the fine sand 3 will push the sealing plate 5 to slide into the transfer groove 4, so that part of the fine sand 3 can enter the interior of the transfer groove 4, thereby reducing the blocking effect of the fine sand 3 on the aluminum plate, so that the I-shaped embossing mold 17 can reach a certain depth standard when embossing the aluminum plate, ensuring the production quality of the product and the feasibility of this solution. In addition, compared with the traditional sliding limit The present invention adopts a positioning design, in which the cooperation of the uniquely shaped T-piece 6 and the slide groove 7 not only supports and limits the sealing plate 5, but also the fine sand 3 entering the transfer groove 4 will not enter the slide groove 7 when the sealing plate 5 slides inwards, thereby avoiding the wear of the precision structure caused by the fine sand 3 when entering the gap, improving the service life of the device, and ensuring the rationality of the structural design. Finally, the sealing plate 5 that may not be reset can be pushed to the opening of the transfer groove 4 by opening the electric push rod 11, thereby ensuring the flow change ability of the fine sand 3 itself when making simple markings.
