[0026] Please also read Figures 1 to 5 , a hydraulic press slider anti-falling structure provided in the embodiment of the present application is now described. The hydraulic press slider anti-falling structure includes a movable hanging plate 100, a fixing seat 200 and a limit assembly. Among them:

[0027] The movable hanging plate 100 has a vertically connected horizontal plate portion 101 and a vertical plate 102. The movable hanging plate 100 is connected to the slider 401 of the hydraulic press through the horizontal plate portion 101 and makes the vertical plate parallel to the sliding direction of the slider 401. The movable hanging plate 100 also has a first connection hole 103 that penetrates the vertical plate. The fixed seat 200 is connected to the top beam 402 of the hydraulic press and forms the partition portions 201 arranged at intervals. The position of the fixed seat 200 corresponds to the movable hanging plate 100 and enables the vertical plate 102 to extend into the interval between adjacent partition portions 201 during the process of rising with the slider 401. The fixed seat 200 also has a second connection hole 202 that penetrates the partition portion 201. The limiting assembly includes a pin shaft 301 and a driving mechanism that is transmission-connected to the pin shaft 301. The pin shaft 301 can be driven by the driving mechanism and extend into the first connection hole 103 and the second connection hole 202.

[0028] According to the above structure provided in the present embodiment, in the anti-fall structure of the slider for the hydraulic press provided in the present embodiment, the movable hanging plate 100 is connected to the slider 401 of the hydraulic press through the horizontal plate and the vertical plate is parallel to the sliding direction of the slider 401, the fixed seat 200 is connected to the top beam 402 of the hydraulic press and has spaced partition parts 201. Since the position of the fixed seat 200 corresponds to the movable hanging plate 100, when the slider 401 rises, the vertical plate 102 of the movable hanging plate 100 connected to the slider 401 can rise with the slider 401 and extend into the interval between adjacent partition parts 201. When the pin shaft 301 in the limiting assembly is inserted into the first connecting hole 103 set on the vertical plate 102 and the second connecting hole 202 set on the partition part 201 under the action of the driving mechanism, the slider 401 can be firmly hung and the slider 401 can be restricted from falling, which has an anti-fall effect far superior to the prior art. In addition, the anti-fall structure of the slider for the hydraulic press provided in the present application is simple and ingenious, and can be easily installed on most existing hydraulic presses, and has a very wide range of applications.

[0029] In another embodiment of the present application, please refer to Figures 1 to 5 , the first connection hole 103 extends into a long hole along the sliding direction of the slider 401. According to the above structure provided in this embodiment, since the position of the slider 401 when stopped cannot be precisely maintained at the same position, the first connection hole 103 is set as a long hole so that the pin 301 can more easily correspond to the first connection hole 103 and pass through the first connection hole 103, which has a good adaptability effect and can also well achieve the technical effect of limiting the slider 401 from falling.

[0030] In another embodiment of the present application, please refer to Figures 1 to 5, the central axes of the first connection hole 103 and the second connection hole 202 are perpendicular to the sliding direction of the slider 401. According to the above structure provided in this embodiment, the first connection hole 103 and the second connection hole 202 are perpendicular to the sliding direction of the slider 401, so that when the pin 301 extends into the first connection hole 103 and the second connection hole 202, the pin 301 can be perpendicular to the sliding direction of the slider 401, thereby maximizing the load capacity of the pin 301, thereby further achieving the technical effect of stably supporting the slider 401 and preventing the slider 401 from falling.

[0031] In another embodiment of the present application, please refer to Figures 1 to 5 The limit assembly also includes a sliding bearing 302 coaxially arranged in the second connection hole 202 and used for sliding connection with the pin 301. According to the above structure provided in this embodiment, by arranging the sliding bearing 302 in the second connection hole 202, the friction coefficient between the pin 301 and the second connection hole 202 can be effectively reduced, thereby effectively reducing the wear of the pin 301 in the process of extending into the second connection hole 202, which is conducive to improving the service life of the anti-fall structure of the slider for the hydraulic press provided in this embodiment.

[0032] In another embodiment of the present application, please refer to Figures 1 to 5 The driving mechanism includes a hydraulic cylinder seat 303 connected to the top beam 402 and a hydraulic cylinder 304 installed on the hydraulic cylinder seat 303. The pin 301 is connected to the power output end of the hydraulic cylinder 304 and driven by the hydraulic cylinder 304. According to the above structure provided in this embodiment, the hydraulic cylinder 304 can stably drive the pin 301 to move along its own axial direction, which is conducive to more smoothly extending into the first connecting hole 103 and the second connecting hole 202, thereby achieving the anti-falling effect of the anti-falling structure of the slider for the hydraulic press in this embodiment. In addition, in this embodiment, the hydraulic cylinder 304 is connected to the top beam 402 through the hydraulic cylinder seat 303, and has good connection stability.

[0033] In another embodiment of the present application, please refer to Figures 1 to 5 The driving mechanism further includes a support 305 connected to the side wall of the top beam 402, and the hydraulic cylinder seat 303 is connected to the top beam 402 through the support 305. According to the above structure provided in this embodiment, the hydraulic cylinder seat 303 is connected to the top beam 402 through the support 305, which has better installation stability on the one hand, and can also flexibly adjust the installation position through the support 305 on the other hand, so as to better adapt to the sliding path of the slider 401, and achieve a better technical effect of preventing the slider 401 from falling.

[0034] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
