Description

Technical Field

[0001] This utility model belongs to the field of hot pressing mold technology, specifically relating to a hot pressing mold for high-strength steel deck. Background Technology

[0002] In the processing of medium-thickness high-strength steel products, hot pressing is widely used to effectively improve the material's plasticity and reduce internal stress and cracking risk. Compared to cold pressing, hot pressing can significantly improve the plasticity of high-strength steel at high temperatures, making it easier to form complex shapes and effectively reducing the risk of cracking caused by internal stress concentration.

[0003] However, in actual production, to meet the diverse production needs of deck products, multiple sets of molds of different specifications are required. Each set of molds requires design, manufacturing, and debugging, which takes a long time and makes it difficult for companies to respond quickly to market changes. In addition, the manufacture and use of multiple sets of molds not only significantly increases the initial investment, but also raises long-term maintenance costs, directly driving up product production costs. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength steel deck hot pressing mold to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength steel deck hot pressing mold, comprising: a punch, a die below the punch, a pressure plate on one side of the punch and die, the pressure plate being "Z"-shaped, T-bolts and hexagonal nuts connecting the punch and pressure plate to the upper worktable of the hydraulic press and the die and pressure plate to the lower worktable of the hydraulic press, hexagonal head bolts installed on the side wall of the die, and lifting pins cast into the die.

[0006] Preferably, the lower surface of the punch protrudes outward, and the upper surface of the die is recessed inward, with the punch and die having correspondingly matched shapes;

[0007] The sidewall of the punch is equipped with a first punch insert and a second punch insert, and both the first punch insert and the second punch insert are connected to the punch with hexagon socket screws.

[0008] The punch has a first positioning plate installed on its side wall, and the die has a second positioning plate installed on its side wall.

[0009] Through the above technical solution:

[0010] In use, the deck to be formed is placed in an industrial resistance furnace and heated to the specific temperature required by the process. From the time the deck is taken out of the furnace to the time it is placed in the hot press mold and the mold is closed, the entire process must be completed within 50 seconds to ensure that the deck is formed at the optimal temperature. Separate the upper and lower worktables of the hydraulic press, place the heated deck to be formed smoothly on the upper surface of the die, start the hydraulic press, and make the upper worktable of the hydraulic press begin to descend. The upper worktable descends until the punch and die are completely closed, and the pressure is held at this position for 5 minutes. The forming process of the deck is completed by the squeezing action of the punch and die.

[0011] Adjust the pressure of the hydraulic press to zero, so that the upper worktable of the hydraulic press begins to move upward, the punch and die separate, the platen that has been pressed is removed, and the hydraulic press is turned off.

[0012] Depending on the forming structure requirements of different products, the first punch insert and the second punch insert can be flexibly replaced. Both punch inserts are equipped with threaded holes and internal hexagon screws for easy and quick replacement, ensuring the versatility and adaptability of the mold.

[0013] Repeat the above steps to complete the forming work for different batches or different specifications of decks.

[0014] The lifting pin is pre-cast into the mold to facilitate lifting operations during production and improve production efficiency; both the punch and die are designed with weight-reducing holes, which effectively reduce the weight of the mold and reduce energy consumption while ensuring the strength of the mold; the pressure plate is Z-shaped, with a simple structure and firm fixation, which can effectively reduce the difficulty of mold assembly and improve the convenience and stability of mold installation; and the side wall of the die assists in positioning, ensuring the precise positioning and stability of the mold during the forming process.

[0015] In summary, quick-change inserts enable rapid mold adjustments; weight-reducing hole design optimizes mold weight; pressure plate structure ensures stability; and the application of positioning plates improves positioning accuracy. These innovative designs endow molds with high efficiency, versatility, and ease of operation, effectively improving production efficiency and product quality, making flexible molds an inevitable choice for industrial production. With its replaceable insert design, flexible molds can quickly adapt to various product shapes, significantly shortening the mold manufacturing cycle and substantially reducing production costs. Simultaneously, combined with hot pressing technology, the molding process can be controlled, improving product quality consistency and reducing material waste and energy consumption. Furthermore, its convenient replacement method further improves production efficiency and reduces long-term operating costs, making it a highly efficient and economical hot pressing solution.

[0016] The pressure plate has an annular mounting groove on its side wall where T-bolts are installed. Multiple receiving grooves are formed around the side wall of the mounting groove. An annular plate is provided inside the mounting groove. A spring connects the mounting groove and the annular plate. Multiple limiting components are installed on the side wall of the annular plate.

[0017] Preferably, the limiting component includes a through groove and a pin, the through groove being formed on the side wall of the annular plate, the pin passing through the through groove, and the pin being adapted to the receiving groove.

[0018] Through the above technical solution:

[0019] In use, after installing the T-bolt onto the pressure plate, pull the annular plate upwards, moving it along the guide groove until the annular plate is higher than the top of the T-bolt. Next, sequentially move each pin towards the end closest to the T-bolt. This action allows the pin to pass through the through-slot of the annular plate and eventually contact the top of the T-bolt. Once the pin is in place, its top presses against the top of the T-bolt. At this point, the spring, through its own elasticity, generates a tendency to pull the annular plate further into the mounting groove. This tendency increases the contact pressure between the pin and the T-bolt, effectively preventing the T-bolt from loosening or falling off under external force or vibration. The engagement of the pin and the T-bolt, along with the additional pressure provided by the spring, together constitute a reliable limiting mechanism, ensuring the T-bolt remains stable during mold operation. This design not only prevents accidental T-bolt detachment but also enhances the stability of the entire structure, ensuring the mold functions normally under high pressure and high temperature environments.

[0020] When the ring plate and pin are not needed for limiting, the spring will pull the ring plate back into the mounting groove using its own elasticity. At this time, the pin will also move and eventually be located in the receiving groove. This design realizes the storage function of the pin and ring plate, avoiding them occupying extra space when not in use, making the entire mold structure more compact and orderly.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] (1) This utility model achieves high efficiency, versatility, and ease of operation by quickly replacing the punch insert, combining a weight-reducing hole design, a simple and robust "Z"-shaped pressure plate, and an auxiliary positioning plate. In the operation process, the deck is heated and quickly placed on the concave mold to complete the mold closure. The mold design not only ensures the consistency of molding quality but also reduces energy consumption and production costs through weight-reducing holes and optimized structure. Its rapid adjustment and stable performance make it an efficient and economical hot pressing solution, suitable for various product specifications, and effectively improves production efficiency and product quality.

[0023] (2) This utility model prevents bolts from falling off by setting up an annular plate and a pin. In use, after installing the T-bolt, pull up the annular plate to a height above the bolt, and move the pin to make it contact the bolt. The spring pulls the annular plate, increasing the pressure between the pin and the bolt to prevent loosening. The cooperation between the pin and the bolt and the spring pressure ensure that the bolt is stable and that the mold works stably. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figures 1-6 As shown, this utility model provides the following technical solution: a high-strength steel deck hot pressing mold, comprising: a punch 1, a die 2 disposed below the punch 1, a pressure plate 8 disposed on one side of the punch 1 and the die 2, the pressure plate 8 being "Z" shaped, T-bolts 9 and hexagonal nuts 10 connecting the punch 1 and the pressure plate 8 to the upper worktable of the hydraulic press, and the die 2 and the pressure plate 8 to the lower worktable of the hydraulic press, hexagonal head bolts 11 being installed on the side wall of the die 2, and lifting pins 12 being poured into the die 2.

[0036] Furthermore, the lower surface of the punch 1 protrudes outward, while the upper surface of the die 2 is recessed inward, with the punch 1 and die 2 having corresponding shapes that are compatible.

[0037] The side wall of the punch 1 is equipped with a first punch insert 5 and a second punch insert 6. Both the first punch insert 5 and the second punch insert 6 are connected to the punch 1 with internal hex screws 7.

[0038] The side wall of the punch 1 is equipped with a first positioning plate 3, and the side wall of the die 2 is equipped with a second positioning plate 4.

[0039] Through the above technical solution:

[0040] In use, the deck to be formed is placed in an industrial resistance furnace and heated to the specific temperature required by the process. From the time the deck is taken out of the furnace to the time it is placed in the hot press mold and the mold is closed, the entire process must be completed within 50 seconds to ensure that the deck is formed at the optimal temperature. Separate the upper and lower worktables of the hydraulic press, place the heated deck to be formed smoothly on the upper surface of the concave mold 2, start the hydraulic press, and make the upper worktable of the hydraulic press begin to descend. The upper worktable descends until the punch 1 and the concave mold 2 are completely closed, and hold the pressure at this position for 5 minutes. The forming process of the deck is completed by the squeezing action of the punch 1 and the concave mold 2.

[0041] Adjust the pressure of the hydraulic press to zero, so that the upper worktable of the hydraulic press begins to move upward, the punch 1 and the die 2 separate, remove the deck that has been pressed, and turn off the hydraulic press.

[0042] Depending on the forming structure requirements of different products, the first punch insert 5 and the second punch insert 6 can be flexibly replaced. Both punch inserts are equipped with threaded holes and internal hexagon screws 7, which facilitates quick replacement and ensures the versatility and adaptability of the mold.

[0043] Repeat the above steps to complete the forming work for different batches or different specifications of decks.

[0044] The lifting pin 12 is pre-cast into the mold to facilitate lifting operations during production and improve production efficiency; both the punch 1 and the die 2 are designed with weight-reducing holes, which effectively reduce the weight of the mold and reduce energy consumption while ensuring the strength of the mold; the pressure plate 8 is Z-shaped, with a simple structure and firm fixation, which can effectively reduce the difficulty of mold assembly and improve the convenience and stability of mold installation; and the side wall of the die 2 assists in positioning, ensuring the accurate positioning and stability of the mold during the forming process.

[0045] In summary, quick-change inserts enable rapid mold adjustments; the weight-reducing hole design optimizes mold weight; the pressure plate 8 structure ensures stability; and the application of positioning plates improves positioning accuracy. These innovative designs endow the mold with high efficiency, versatility, and ease of operation, effectively improving production efficiency and product quality, making flexible molds an inevitable choice for industrial production. With its replaceable insert design, flexible molds can quickly adapt to various product shapes, significantly shortening the mold manufacturing cycle and substantially reducing production costs. Simultaneously, combined with hot pressing technology, the molding process can be controlled, improving product quality consistency and reducing material waste and energy consumption. Furthermore, its convenient replacement method further improves production efficiency and reduces long-term operating costs, making it a highly efficient and economical hot pressing molding solution.

[0046] Please see Figure 1 and Figures 7-9 As shown, the side wall of the pressure plate 8 where the T-bolt 9 is installed has an annular mounting groove 13. The side wall of the mounting groove 13 has multiple receiving grooves 18. An annular plate 14 is provided in the mounting groove 13. A spring 15 is connected between the mounting groove 13 and the annular plate 14. Multiple limiting components are installed on the side wall of the annular plate 14.

[0047] Furthermore, the limiting component includes a through groove 16 and a pin 17. The through groove 16 is formed on the side wall of the annular plate 14, and the pin 17 passes through the through groove 16 and is adapted to the receiving groove 18.

[0048] Through the above technical solution:

[0049] In use, after installing the T-bolt 9 onto the pressure plate 8, pull the annular plate 14 upwards, moving it along the guide of the mounting groove 13 until the position of the annular plate 14 is higher than the top of the T-bolt 9. Next, sequentially move each pin 17 towards the end closest to the T-bolt 9. This action causes the pin 17 to pass through the through slot 16 of the annular plate 14 and finally contact the top of the T-bolt 9. When the pin 17 is in place, its top presses against the top of the T-bolt 9. At this time, the spring 15, through its own elasticity, generates a tendency to pull the annular plate 14 into the mounting groove 13. This tendency increases the contact pressure between the pin 17 and the T-bolt 9, effectively preventing the T-bolt 9 from loosening or falling off under external force or vibration. The cooperation between the pin 17 and the T-bolt 9, along with the additional pressure provided by the spring 15, together constitute a reliable limiting mechanism, ensuring that the T-bolt 9 remains stable during mold operation. This design not only prevents the T-bolt 9 from accidentally falling off, but also enhances the stability of the entire structure, ensuring that the mold can work normally under high pressure and high temperature.

[0050] When the annular plate 14 and pin 17 are not needed for limiting, the spring 15 will pull the annular plate 14 back into the mounting groove 13 by its own elastic force. At this time, the pin 17 will also move and eventually be located in the receiving groove 18. This design realizes the storage function of the pin 17 and the annular plate 14, avoiding them occupying extra space when not in use, making the entire mold structure more compact and orderly.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
