Description

Technical Field

[0001] This utility model relates to the field of flange manufacturing technology, specifically a high-efficiency double-disc friction press. Background Technology

[0002] Flanges are key components in piping systems used for connection, sealing, and support. Their manufacturing process must take into account material properties and processing precision requirements. The quality of flanges directly affects the safety and sealing of the piping system. Therefore, the manufacturing process must strictly follow industry specifications and technical standards.

[0003] In the existing design, the friction discs contact the flywheel simultaneously, and the flywheel is driven to rotate by the rotation of the two sets of friction discs. However, the contact area of ​​the two sets of friction discs is limited. Once slippage occurs, the flywheel cannot be driven to rotate, thus affecting the forging efficiency of the workpiece.

[0004] To overcome the above-mentioned defects, the prior art (Chinese patent publication number: CN117103747A, publication date: 2023-11-24) discloses a friction press, including a support plate, a support column, a motor, a first friction disc, a flywheel, a first screw, a threaded sleeve, a forging hammer, and a forging seat. The support column is symmetrically fixedly arranged on the lower surface of the support plate. A first fixed plate and a second fixed plate are respectively fixedly arranged on both sides of the upper surface of the support plate. A first rotating shaft is rotatably arranged on the opposite side of the first fixed plate and the two first rotating shafts are fixedly connected to the first friction disc at opposite ends. The motor is fixedly installed on the side of the first fixed plate, and the output end of the motor is fixedly connected to one end of the first rotating shaft. The first screw is vertically rotatably arranged in the middle of the support plate, and the lower end of the first screw is threadedly connected to the threaded sleeve. This friction press increases the contact area between the friction disc and the flywheel, avoids slippage between the friction disc and the flywheel, and allows the forging hammer to be disassembled and replaced, thus improving processing efficiency.

[0005] While the above design can solve the aforementioned problems, the workpiece needs to be manually removed after processing, which makes the equipment very inconvenient to use and reduces processing efficiency. It cannot efficiently and quickly process flanges. At the same time, the existing design does not provide sufficient protection for processing personnel during processing. If no protection is provided, flying iron filings during processing can cause injury to workers. Utility Model Content

[0006] The purpose of this utility model is to provide a high-efficiency double-disc friction press to solve the problem mentioned in the background art that the workpiece needs to be manually removed after processing, which makes the use of the equipment very inconvenient and reduces processing efficiency. It is also impossible to process flanges efficiently and quickly. At the same time, the existing design does not provide enough protection for the processing personnel during processing. If the iron filings that fly during processing are not protected, they will cause injury to the workers.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency double-disc friction press, comprising a support and stabilizing frame and a lower support plate. A drive rotary motor is installed on the top of the support and stabilizing frame. A rotational elastic mechanism for ejecting the workpiece is installed on the outer surface of the output end of the drive rotary motor. The rotational elastic mechanism includes a double-disc wheel rod, which is fixedly installed on the outer surface of the output end of the drive rotary motor. A through-mounting groove is provided on the upper surface of the lower support plate, and a meshing transmission mechanism for moving the protective sliding plate upward is installed inside the through-mounting groove.

[0008] Furthermore, the meshing transmission mechanism includes a first meshing rack, which is fixedly installed on the front and rear sides of the pressing rod. A central transmission gear is installed inside the through mounting groove, and the downward trajectory of the first meshing rack is in contact with the outer surface of the central transmission gear.

[0009] Furthermore, an auxiliary sliding frame is installed on the upper surface of the lower support plate, and a protective sliding plate is installed inside the auxiliary sliding frame. A second meshing rack is installed on the lower surface of the protective sliding plate, and the second meshing rack meshes with the intermediate transmission gear.

[0010] Furthermore, a driven disk is installed inside the top of the support and stabilizing frame, and a lower support plate is installed inside the support and stabilizing frame. A rotating fitting groove is opened on the upper surface of the lower support plate, and an L-shaped rotating rod is installed inside the rotating fitting groove. A pressing rod is installed on the lower surface of the center position of the driven disk, and two abutting rods are installed on the outer surface of the pressing rod.

[0011] Furthermore, an L-shaped rotating rod is installed on the inner surface of the rotating fitting inner groove, and the downward trajectory of the two side abutting rods abuts against the end of the L-shaped rotating rod. A spring lifting member is installed on the top of the L-shaped rotating rod, and the rotation trajectory of the spring lifting member passes through a circular hole opened at the top of the rotating fitting inner groove.

[0012] Furthermore, a hollow connecting rod is installed on the upper surface of the lower support plate, and the installation position of the hollow connecting rod corresponds to the downward movement trajectory of the pressing rod. Two sets of the two side contact rods, L-shaped rotating rods and spring lifting parts are symmetrically installed about the center point of the lower support plate, and the L-shaped rotating rod is rotatably installed inside the rotating fitting groove.

[0013] Furthermore, the protective sliding plate and the second meshing rack are designed as a single unit, and the sliding trajectory of the protective sliding plate corresponds to the installation position of the hollow connecting rod. The outer surface of the first meshing rack contacts the outer surface of the central transmission gear to form a meshing structure, and the side of the protective sliding plate contacts the inner surface of the auxiliary sliding frame to form a sliding structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When the lower pressing rod and the hollow docking rod are docked by connecting the driven disc, the two side abutting rods will abut against the side of the L-shaped rotating rod to make it rotate, ensuring that the spring lifting part abuts against the lower surface of the workpiece. After the processing is completed, the elasticity of the spring lifting part will automatically push the finished product out. This design eliminates the need to manually remove the workpiece after processing, improves the processing efficiency of the equipment, and enables efficient and fast processing of flanges. Furthermore, when the pressing rod and the hollow docking rod are docked, the first meshing rack will lift the second meshing rack through the central transmission gear, so that the through-mounted inner groove will completely shield the outside of the hollow docking rod. This design makes the equipment more protective for processing personnel and prevents iron filings from flying. Furthermore, the top opening shape of the rotating fitting inner groove corresponds to the top disc design of the spring lifting component. This design makes the equipment more intelligent and faster to use, and ensures that the lifting operation of the workpiece is more stable. Attached Figure Description

[0017] 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.

[0018] Example 1: Please refer to Figure 2 , Figure 3 and Figure 4 This utility model provides the following technical solution: a high-efficiency double-disc friction press, including a support and stabilizing frame 1 and a lower support plate 7. A drive rotary motor 2 is installed on the top of the support and stabilizing frame 1. A rotating elastic mechanism for ejecting the workpiece is installed on the outer surface of the output end of the drive rotary motor 2. The rotating elastic mechanism includes a double-disc wheel rod 3, such as... Figure 3 As shown, the double disc wheel rod 3 is fixedly installed on the outer surface of the output end of the drive rotary motor 2, and the upper surface of the lower support plate 7 is provided with a through mounting groove 13, and the inside of the through mounting groove 13 is equipped with a meshing transmission mechanism for moving the protective sliding plate 14 upward.

[0019] like Figure 2 , Figure 3 and Figure 4 The technical solution shown addresses the problem of inconvenient and inefficient operation of flanges due to the need for manual removal of the workpiece after processing, which hinders efficient and rapid flange processing. It discloses the following: a driven disc 4 is installed inside the top of the support frame 1, and a lower support plate 7 is installed inside the support frame 1. The upper surface of the lower support plate 7 has a rotating engagement groove 9, and an L-shaped rotating rod 11 is installed inside the rotating engagement groove 9. A pressing rod 5 is installed on the lower surface of the driven disc 4 at its center, and two abutment rods 6 are installed on the outer surface of the pressing rod 5. The inner surface of the rotating engagement groove 9 is equipped with the L-shaped rotating rod 11, and the downward trajectory of the two abutment rods 6 abuts against the end of the L-shaped rotating rod 11. Figure 4 As shown, a spring lifting member 12 is installed on the top of the L-shaped rotating rod 11, and the rotation trajectory of the spring lifting member 12 passes through a circular hole opened on the top of the rotating fitting inner groove 9. A hollow connecting rod 8 is installed on the upper surface of the lower support plate 7, and the installation position of the hollow connecting rod 8 corresponds to the downward movement trajectory of the downward pressing rod 5. Two sets of abutment rods 6, L-shaped rotating rod 11 and spring lifting member 12 are symmetrically installed on the left and right sides about the center point of the lower support plate 7, and the L-shaped rotating rod 11 is rotatably installed inside the rotating fitting inner groove 9.

[0020] When processing of the workpiece is required, the drive rotary motor 2, which is fixedly installed on the side of the support and stabilizing frame 1, is directly started to rotate. At this time, the drive rotary motor 2 will synchronously drive the double disc wheel rod 3, which is fixedly installed on the outer surface of its output end, to rotate. During this process, the driven disc 4 will be synchronously driven with the pressing rod 5, which is fixedly installed at the center of the lower surface. During the downward stable movement of the pressing rod 5, the two abutment rods 6 fixedly installed on the outer surface of the pressing rod 5 will be synchronously driven. Figure 4 As shown, during the downward movement of the two side contact rods 6, they will contact the side of the L-shaped rotating rod 11. Since the two sides of the L-shaped rotating rod 11 are rotatably installed inside the rotating fitting groove 9 opened on the inner surface of the lower support plate 7, the top of the L-shaped rotating rod 11 will be correspondingly lifted. The lifting operation of the L-shaped rotating rod 11 will squeeze the spring lifting member 12 fixedly installed at the top and completely fit it with the bottom surface of the workpiece. Due to the contact between the two side contact rods 6 and the L-shaped rotating rod 11, the contact effect of the spring lifting member 12 is more stable. After the workpiece is processed, the spring lifting member 12 releases elastic potential energy to lift the processed workpiece. This design makes the use of the equipment more intelligent and labor-saving.

[0021] Example 2: Figure 1 , Figure 5 , Figure 6 and Figure 7 The technical solution shown addresses the problem of insufficient protection for workers during machining operations, where flying iron filings can cause injury without proper protection. It discloses a meshing transmission mechanism including a first meshing rack 10, fixedly mounted on the front and rear sides of the downward pressing rod 5. A central transmission gear 16 is installed inside the through-groove 13, and the downward trajectory of the first meshing rack 10 contacts the outer surface of the central transmission gear 16. Figure 5As shown, an auxiliary sliding frame 15 is installed on the upper surface of the lower support plate 7, and a protective sliding plate 14 is installed inside the auxiliary sliding frame 15. A second meshing rack 17 is installed on the lower surface of the protective sliding plate 14, and the second meshing rack 17 meshes with the intermediate transmission gear 16. The protective sliding plate 14 and the second meshing rack 17 are designed as a single piece, and the sliding trajectory of the protective sliding plate 14 corresponds to the installation position of the hollow connecting rod 8. The outer surface of the first meshing rack 10 contacts the outer surface of the intermediate transmission gear 16 to form a meshing structure, and the side of the protective sliding plate 14 contacts the inner surface of the auxiliary sliding frame 15 to form a sliding structure.

[0022] As the pressing rod 5 moves downward, the first meshing racks 10 fixedly installed on both sides of the pressing rod 5 will slide down synchronously until the pressing rod 5 enters the hollow connecting rod 8 installed on the upper surface of the lower support plate 7. At this time, the outer surface of the first meshing rack 10 will contact the central transmission gear 16 rotatably installed inside the through-mounted inner groove 13 and drive it. After being driven by the meshing motion, the central transmission gear 16 will rotate continuously. In the rotation of the central transmission gear 16, the second meshing rack 17, which is in contact with the outer surface, will mesh again and drive it. Figure 6 As shown, since the top of the second meshing rack 17 is fixedly installed on the lower surface of the protective sliding plate 14, the protective sliding plate 14 will be driven to slide vertically upward. During the movement of the protective sliding plate 14, it will move along the inside of the auxiliary sliding frame 15 fixedly installed on the top of the support and stabilizing frame 1 to limit and fit until the pressing rod 5 and the hollow docking rod 8 are stably fitted and docked. At this time, the protective sliding plate 14 slides to the limit position and the fixed position of the protective sliding plate 14 will complete the internal shielding and protection of the outside of the hollow docking rod 8. This design makes the use of the equipment safer.
