Description

Technical Field

[0001] This utility model relates to the field of press technology, specifically a safety-type open fixed-table press. Background Technology

[0002] A press is a mechanical device that uses a specific power source (such as mechanical transmission, hydraulic or pneumatic systems) to generate pressure and apply external force to a workpiece to achieve processing such as forming, punching, stretching, and straightening. It is widely used in industrial manufacturing and is one of the core pieces of equipment in metal processing, plastic molding, automobile manufacturing, aerospace and other fields. Open-type fixed-table presses are a common type of mechanical press. Due to their open structure, flexible operation and low cost, they are widely used in small and medium-sized metal stamping processing scenarios. When the press is working, the waste generated during processing falls from the corresponding hole in the middle of the platform and slides out from the front end of the platform, avoiding the accumulation of waste on the platform which is difficult to clean. However, most metal workpieces generate a certain amount of debris in addition to waste during processing. If the debris accumulates on the platform for a long time, it will also affect the processing of the workpiece. Moreover, the debris is small in size and cannot be cleaned up.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application number 202322822149.5, application date 2023-10-20) provides an open-type fixed-table press, including a press body, a base fixedly installed at the bottom of the press body, and an open-type fixed table assembled on the outside of the press body. A pressure mechanism corresponding to the position of the open-type fixed table is provided at the top of the press body. This open-type fixed-table press, through the combined use of a storage box, a fan, a spray pipe, and an electric telescopic column, allows the press to complete the processing of the workpiece above the open-type fixed table. After the workpiece is processed, the electric telescopic column can operate and drive the spray pipe through its drive shaft to move, lifting the spray pipe to a position corresponding to the top of the open-type fixed table. Simultaneously, the fan operates and generates an air jet, which enters the spray pipe and is ejected through the spray hole, blowing away residual debris on the open-type fixed table into the storage box for storage, ensuring the cleanliness of the open-type fixed table and avoiding affecting the processing of subsequent workpieces.

[0004] The hardness varies in different parts of the billet. During forging, the areas with lower hardness will deform first, while the deformation degree of the areas with higher hardness is inconsistent with that of the areas with lower hardness. Stress concentration is likely to occur at the transition points between the two. When the stress exceeds the material's strength limit, it will cause the material to break and form debris. During use, the above-mentioned device cannot effectively reduce debris splashing, which may cause debris to hit the operator, reducing the operator's personal safety. At the same time, the debris will enter the press, accelerating the wear of the press and reducing its service life. Utility Model Content

[0005] The purpose of this invention is to provide a safe open-type fixed-table press to solve the problems mentioned in the background art, such as the inability to effectively reduce debris splashing, which causes debris to hit the operator and reduce the operator's personal safety, and the fact that debris can enter the press, accelerate the wear of the press, and reduce the service life of the press.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a safety-type open-type fixed-table press, comprising a frame, a worktable fixedly connected to the lower front end of the frame, and a motor fixedly connected to the upper rear end of the frame, with a rotating shaft fixedly connected to the output end of the motor, the rotating shaft being rotatably disposed inside the frame; a limit rod fixedly connected to one end of the frame surface near the worktable, the limit rod being slidably connected to a stamping assembly, and a sliding rod connected inside the frame via a reciprocating sliding structure, the sliding rod being slidably connected to a protective plate; a cylinder fixedly connected to the surface of the rotating shaft, the cylinder being rotatably disposed inside the frame, and one end of a connecting rod being slidably connected to the surface of the cylinder, the other end of the connecting rod being slidably connected to the stamping assembly.

[0007] Preferably, a fixing block is fixedly connected to the lower end of the frame, and a drive shaft is rotatably installed inside the fixing block, and belts are sleeved and connected to both the surface of the drive shaft and the surface of the rotating shaft.

[0008] Preferably, a sliding shaft is rotatably provided inside the worktable, and bevel gears are fixedly connected to both the surface of the sliding shaft and the surface of the transmission shaft, and a support frame is fixedly connected to the surface of the sliding shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This safety-type open fixed-table press adopts a novel structural design, the specific details of which are as follows: (1) The safety type open fixed table press can effectively block the generated splashes through the protective plate and sliding rod, prevent them from injuring the operators, reduce the risk of accidental injury, and ensure personnel safety. In addition, the protective plate can block external debris and dust from entering the press, reduce the erosion of the press by environmental factors, and maintain the stable performance of the equipment.

[0014] Furthermore, it prevents dust from entering the transmission components, reduces wear, extends the service life of the equipment, and also makes it easier for staff to clean and tidy up the surrounding environment of the equipment.

[0015] (2) This safety-type open fixed table press, through the set lubricant tank and connecting pipe, can make the lubricant cover all surfaces and corners of the mold, ensuring that the entire mold is uniformly lubricated. At the same time, it can effectively reduce the friction coefficient between the mold and the billet, reduce wear, extend the service life of the mold, and improve the forging quality.

[0016] Furthermore, it allows the lubricant to penetrate better into the tiny gaps and surface texture of the mold, enhancing the lubrication effect and ensuring good lubrication conditions throughout the forging process.

[0017] (3) The safety type open fixed table press improves the stability of the device during operation by setting the frame and fixed block, and can prevent the equipment from deforming due to force, enhance the connection between each component and the frame, and at the same time ensure the straightness and verticality of the slide movement, so that the inner flange of the forging has higher dimensional accuracy and reduces the scrap rate.

[0026] 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.

[0027] Example 1: The frame 1, cylinder 4, and sliding rod 11 improve the stability of the device during operation and prevent deformation of the equipment due to stress. Figures 1-3 As shown: It includes a frame 1, a worktable 10 is fixedly connected to the lower front end of the frame 1, and a motor 2 is fixedly connected to the upper rear end of the frame 1. The output end of the motor 2 is fixedly connected to a rotating shaft 3, and the rotating shaft 3 is rotatably disposed inside the frame 1. A limit rod 7 is fixedly connected to one end of the surface of the frame 1 near the worktable 10, and a stamping assembly 6 is slidably connected through the limit rod 7. A sliding rod 11 is connected inside the frame 1 through a reciprocating sliding structure, and a protective plate 12 is slidably connected through the sliding rod 11. A cylinder 4 is fixedly connected to the surface of the rotating shaft 3, and the cylinder 4 is rotatably disposed inside the frame 1. One end of a connecting rod 5 is slidably connected to the surface of the cylinder 4, and the other end of the connecting rod 5 is slidably connected to the stamping assembly 6.

[0028] Workers install a mold compatible with the inner flange forging process on workbench 10, ensuring the mold is accurately positioned and securely fixed to prevent displacement during the forging process (e.g., Figure 1 As shown), this is the operator starting the motor 2. The motor 2 drives the output shaft 3 to rotate inside the frame 1, and the shaft 3 drives the cylinder 4 on the surface to rotate inside the frame 1. At the same time, as the cylinder 4 rotates, it drives the connecting rod 5 to slide, causing the connecting rod 5 to drive the lower stamping assembly 6 to slide on the surface of the limit rod 7, thus forging the flange at the upper end of the worktable 10 (as shown). Figure 2 and Figure 3As shown), the protective plate 12 on the surface of the workbench 10 can prevent operators from coming into contact with dangerous areas (such as...) during equipment operation. Figure 4 As shown), at the same time, the lubricant inside the lubricant tank 22 is evenly sprayed onto the processing area through the connecting pipe 23 to ensure that the entire mold is evenly lubricated (as shown). Figure 7 As shown in the figure, this ensures the straightness and perpendicularity of the slider movement, resulting in higher dimensional accuracy of the forged inner flange and reducing the scrap rate.

[0029] In Example 2, unlike Example 1, the transmission shaft 9, support frame 15, and moving rod 16 effectively block the splashing debris, preventing injury to operators. Figures 3-5 As shown: A fixed block 8 is fixedly connected to the lower end of the frame 1, and a transmission shaft 9 is rotatably installed inside the fixed block 8. Belts are sleeved and connected to both the surface of the transmission shaft 9 and the surface of the rotating shaft 3. A sliding shaft 14 is rotatably installed inside the worktable 10, and bevel gears 13 are fixedly connected to both the surface of the sliding shaft 14 and the surface of the transmission shaft 9. A support frame 15 is fixedly connected to the surface of the sliding shaft 14. The reciprocating sliding structure includes a support frame 15 fixedly connected to the surface of the sliding shaft 14. One end of a moving rod 16 is slidably connected to the surface of the support frame 15, and a protective plate 12 is slidably connected to the other end of the moving rod 16. The protective plate 12 is slidably installed on the upper end of the worktable 10.

[0030] Belts are fitted onto both the surface of the rotating shaft 3 and the surface of the transmission shaft 9. Through belt drive, the rotating shaft 3 drives the transmission shaft 9 to rotate within the fixed block 8 (e.g., ...). Figure 3 As shown), bevel gears 13 are installed on the surfaces of the drive shaft 9 and the sliding shaft 14, so that when the drive shaft 9 is working, it drives the sliding shaft 14 to rotate inside the worktable 10. As the sliding shaft 14 drives the support frame 15 to rotate at the lower end of the worktable 10, the support frame 15 drives the moving rod 16 on its surface to slide, so that the moving rod 16 drives the protective plate 12 at the other end to slide on the surface of the sliding rod 11 (as shown). Figure 4 and Figure 5 As shown, the protective plate 12 can effectively block these splashes, prevent them from injuring operators, reduce the risk of accidental injury, and ensure personnel safety. In addition, the protective plate 12 can block external debris and dust from entering the press, reduce the erosion of the press by environmental factors, maintain the stability of equipment performance, and facilitate the cleaning of debris generated by the staff.

[0031] In Example 3, unlike Example 2, the sliding sleeve 21, protrusion 18, and fixing bracket 20 ensure that the lubricant covers all surfaces and corners of the mold, guaranteeing uniform lubrication of the entire mold. Figures 6-7As shown: A movable shaft 19 is rotatably connected to the upper left side of the frame 1, and a fixed frame 20 is fixedly connected to the surface of the movable shaft 19. A sliding sleeve 21 is slidably connected to the surface of the fixed frame 20. A connecting shaft 17 is rotatably connected to the upper left side of the frame 1, and belts are sleeved and connected to both the surface of the connecting shaft 17 and the surface of the transmission shaft 9. A protrusion 18 is fixedly connected to the surface of the connecting shaft 17, and the protrusion 18 is slidably disposed on the surface of the sliding sleeve 21. A lubricant tank 22 is fixedly connected to the lower left side of the frame 1, and a connecting pipe 23 is fixedly connected to the upper surface of the lubricant tank 22. The connecting pipe 23 is fixedly connected to the lower end of the movable shaft 19.

[0032] A belt is fitted onto both the surface of the connecting shaft 17 and the surface of the drive shaft 9. Through belt drive, the connecting shaft 17 causes the end protrusion 18 to slide on the surface of the sliding sleeve 21 (e.g., ...). Figure 6 As shown), and as the protrusion 18 slides on the surface of the sliding sleeve 21, the sliding sleeve 21 slides on the surface of the fixed frame 20. Through the friction between the sliding sleeve 21 and the fixed frame 20, the protrusion 18 drives the moving shaft 19 to reciprocate on the outside of the frame 1 (as shown). Figure 7 As shown in the figure, the lubricant inside the lubricant tank 22 is evenly sprayed into the processing area through the connecting pipe 23, ensuring that the entire mold is evenly lubricated. At the same time, it effectively reduces the coefficient of friction between the mold and the blank, reduces wear, extends the service life of the mold, and improves the forging quality.

[0033] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] 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.
