Description

Technical Field

[0001] The utility model relates to the technical field of safety protection of hydraulic presses, and in particular to a safety supporting device for hydraulic presses. Background Art

[0002] An oil press, also known as a hydraulic press, is a device that uses liquid pressure to transmit force and drive the hydraulic cylinder to produce mechanical movement. The oil press uses liquid to transmit pressure to generate force and drive mechanical movement. The hydraulic pump delivers hydraulic oil to the hydraulic cylinder, and the piston generates force to drive mechanical movement. The incompressibility of the hydraulic fluid ensures that the force transmission is more accurate and stable, making it suitable for many applications that require high precision and high force, such as plastic molding, metal pressing, rolling and other processes. Since the oil press mainly drives the pressure head to perform pressing and processing operations on the workpiece during operation, it is necessary to perform pressing and installation work.

[0003] In the related art, during the use of the hydraulic press, a safety shield is generally installed on the outside of the pressing table to cover the moving parts of the hydraulic press to prevent the operator from accidentally touching or entering the dangerous area, reduce the occurrence of accidental injuries, and ensure that the safety of the hydraulic press is sufficient to support production and processing, so that it can be used.

[0004] However, during the current use of the hydraulic press, due to the way of installing protective covers around the moving parts of the hydraulic press, the staff are required to frequently move the safety protective covers to perform safety protection work, which makes the use of the hydraulic press safety protection more cumbersome, and position displacement is prone to occur during frequent movements, and even causes unexpected movement of the pressure head, affecting the convenience and safety of the use and processing of the hydraulic press.

[0032] Reference Figure 1-Figure 4 In a preferred embodiment, the follower protection mechanism includes a follower seat 4, which is fixedly connected to both sides of the front side of the pressure head 3, and the interior of the follower seat 4 is rotatably connected to a force-applying rod 5 through an axle pin, and a fixed seat 6 is fixedly connected to both sides of the top of the press platform 1, and the interior of the fixed seat 6 is rotatably connected to a force-bearing rod 7 movably connected to the force-applying rod 5 through an axle pin, and a protection rod 8 is fixedly connected to the inner side of the force-bearing rod 7, and a protection plate 9 located at the rear side of the protection rod 8 is fixedly connected to the front side of the top of the press platform 1, and a magnetic follower mechanism is movably connected to the rear side of the protection plate 9. When the oil cylinder 2 drives the pressure head 3 to move downward to cooperate with the external mold to press the workpiece, the follower seat 4 uses the moving force of the pressure head 3 to apply a disengagement to the force-bearing rod 7 through the force-applying rod 5 to tilt forward, so that the force-bearing rod 7 The rod 7 pushes the protective rod 8 to move outward, and the protective rod 8 cooperates with the protective plate 9 to form a protective fence outside the working pressure head 3. The magnetic following mechanism includes a following plate 10, a magnetic strip 11 and an observation port 12. The following plate 10 is movably connected to the rear side of the protective plate 9, and the magnetic strip 11 is embedded and connected to both sides of the front side of the following plate 10. The front side of the magnetic strip 11 is magnetically connected to the rear side of the protective plate 9.

When the protective plate 9 is used in conjunction with the protective rod 8, it can follow the movement and lifting of the fixed seat 6, and perform adaptive following work on the protection range and opening and closing of the protective plate 9, so as to avoid the situation where the protective plate 9 is difficult to adapt to the working protection requirements of the pressure head 3 when in use, thereby improving the protection flexibility and adaptability of the protective plate 9.

[0033] Reference Figure 3-Figure 3In a preferred embodiment, a stop opening 13 is provided on the rear side of the follower plate 10, and a stop frame 14 is movably connected to the top of the stop opening 13, and the front side of the stop frame 14 is fixedly connected to the rear side of the protective plate 9. When the follower plate 10 is used in conjunction with the protective plate 9, a blocking and limiting operation can be performed between the protective plate 9 and the follower plate 10 to avoid the follower plate 10 being separated from the protective plate 9 when in use, thereby improving the working stability of the follower plate 10. A connecting groove 15 is provided on the outer side of the force-applying rod 5, and a connecting seat 16 is movably connected to the inside of the connecting groove 15. The outer side of the connecting seat 16 is fixedly connected to the inner side of the force-bearing rod 7. When the force-applying rod 5 is used in conjunction with the force-bearing rod 7, a movably connected operation can be performed between the force-applying rod 5 and the force-bearing rod 7 to avoid the force-applying rod 5 being separated from the force-bearing rod 7 when working, thereby improving the connection effect between the force-applying rod 5 and the force-bearing rod 7.

[0034] Reference Figure 3 In a preferred embodiment, a magnetic disk 17 is embedded and connected at the bottom of the inner side of the inner wall of the connecting groove 15, and a rear magnetic suction cup 18 is embedded and connected on the inner side of the connecting seat 16. The magnetic suction cup 18 is magnetically connected to the magnetic disk 17. When the connecting seat 16 is used in conjunction with the force-applying rod 5 and the force-bearing rod 7, a force-applying effect can be achieved through a magnetic suction connection between the connecting seat 16, the force-applying rod 5 and the force-bearing rod 7, thereby avoiding the situation where it is difficult to apply force to the force-bearing rod 7 when the force-applying rod 5 is used, thereby improving the force-applying effect of the force-applying rod 5 on the force-bearing rod 7. Both sides of the top of the pressing platform 1 are fixedly connected to a limiting seat 19, which is located on the rear side of the fixed seat 6. The front side of the limiting seat 19 contacts the rear side of the force-bearing rod 7. When the force-applying rod 5 is used in conjunction with the force-bearing rod 7, the movable direction of the force-bearing rod 7 can be limited, thereby avoiding the situation where the force-bearing rod 7 moves toward the bottom of the pressing head 3 when working, thereby improving the activity limiting effect of the force-bearing rod 7.

[0035] Reference Figure 3 In a preferred embodiment, a contact seat 20 is installed inside the fixed seat 6, the bottom of the contact seat 20 is fixedly connected to the top of the pressure platform 1, the rear side of the contact seat 20 is fixedly connected to the front side of the limit seat 19, and the top of the contact seat 20 contacts the bottom of the force-bearing rod 7. When the force-applying rod 5 applies force to the force-bearing rod 7, the force-bearing rod 7 can drive the protective rod 8 to move excessively when the force-bearing rod 7 is working, thereby improving the working stability of the force-bearing rod 7. An opening 21 is provided at the bottom of the force-applying rod 5, and the top of the opening 21 is connected to the bottom of the connecting groove 15. The opening 21 is used in conjunction with the connecting groove 15 and the connecting seat 16. When the connecting groove 15 is used in conjunction with the connecting seat 16, a sewage discharge space can be provided for the connecting groove 15 to avoid the situation where dirt particles enter the connecting groove 15 and are difficult to be discharged from the connecting groove 15, resulting in obstruction of the connection seat 16, thereby improving the working smoothness of the connection seat 16.

[0036] Specifically, the working process or working principle of the hydraulic press safety support device is as follows: when in use, after the pressing mold is installed on the top of the pressing head 3, according to the actual pressing opening and closing range of the pressing head 3, the handheld follower plate 10 drives the magnetic strip 11 to move upward, so that the top of the follower plate 10 and the downward movement position of the pressing head 3 move to, in preparation for the subsequent magnetic strip 11 to contact and magnetically attract the follower seat 4. When the oil cylinder 2 starts to drive the pressing head 3 to move downward, the follower seat 4 follows the pressing head 3 to move downward and applies a downward force source to the force rod 5. In this process, the force rod 5 applies force to the force rod 7 through the connecting seat 16, the magnetic disk 17 and the magnetic suction cup 18. After the force rod 7 is subjected to force, it drives the protective rod 8 to move toward the front side of the pressing head 3. At this time, the limiting seat 19 cooperates with the contact seat 20 to perform contact limiting work on the active tilting direction and tilting angle of the force-bearing rod 7, so that the force-bearing rod 7 is parallel to the pressing platform 1 after being tilted by the force, so that the protective rod 8 cooperates with the protective plate 9 to form a protective fence on the front side of the pressing head 3. At the same time, as the force-applying rod 5 applies force to the force-bearing rod 7 through the following seat 4, the force-bearing rod 7 lies flat on the top of the contact seat 20, and the magnetic disk 17 is separated from the magnetic suction cup 18 by the force-applying rod 5 following the downward force of the pressing head 3 through the following seat 4. At the same time, the connecting seat 16 moves inside the connecting groove 15 to perform sliding connection work between the force-applying rod 5 and the force-bearing rod 7. When the oil cylinder 2 drives the pressing head 3 to move downward to the pressing position, the front side of the following plate 10 The magnetic strip 11 contacts the follower seat 4, and is magnetically connected with the pressure head 3 through the follower seat 4 and the follower plate 10. When the oil cylinder 2 drives the pressure head 3 to move upward and reset, the follower plate 10 cooperates with the follower seat 4 to follow the pressure head 3 to move upward through the magnetic strip 11 to perform magnetic following adaptive following work on the protection range of the protective plate 9. At the same time, the retaining frame 14 moves inside the stall 13 to perform active connection and blocking and limiting work between the follower plate 10 and the protective plate 9. At this time, the follower seat 4 follows the pressure head 3 to move upward and drive the force rod 5 to reset. As the force rod 5 moves upward, the connecting seat 16 moves inside the connecting groove 15, so that the force rod 5 applies an upward flipping reset force to the force-bearing rod 7. When the force rod 5 After the force rod 7 is driven to reset by the connecting column, the magnetic disk 17 contacts the magnetic suction cup 18 again, and the magnetic connection between the force rod 5 and the force rod 7 is performed through the connecting seat 16, so as to prepare for the subsequent force rod 5 to push the protection rod 8 through the force rod 7 to cooperate with the protection plate 9 to form a protection fence on the front side of the pressure head 3, and repeatedly follow the movement of the pressure head 3 to form a retractable pressure head 3 pressing protection fence on the front side of the pressure head 3. When the connecting seat 16 is used in conjunction with the force rod 5 and the force rod 7 through the connecting groove 15, the dirt particles entering the connecting groove 15 are discharged from the connecting groove 15 through the opening 21 when the force rod 5 moves. The use of the follower plate 10 needs to be selectively used according to the actual pressing processing requirements.

[0037] It should be noted that the oil cylinder 2 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they are not described in detail.
